Closing Price (as reflected on Nasdaq.com) immediately preceding the Effective Date; or (ii) the average Nasdaq Official Closing Price

completed a series of transactions that resulted in the combination (the &#8220;<b>Business Combination</b>&#8221;) of ACAB with Abpro
Corporation pursuant to the previously announced Business Combination Agreement, dated December 11, 2023, amended by an amendment dated

at the special meeting of the shareholders of ACAB held on November 7, 2024 (the &#8220;<b>Special Meeting</b>&#8221;). On November 12,

Statement/Prospectus</b>&#8221;), Merger Sub merged with and into Abpro Corporation, with Abpro Corporation surviving the merger as a
wholly owned subsidiary of ACAB, and ACAB changed its name to Abpro Holdings, Inc. As consideration for the Business Combination, New
Abpro issued to or reserved for Abpro Corporation shareholders an aggregate of approximately 50,000,000 shares of Common Stock, consisting
of 39,123,200 shares of Common Stock issued to Abpro Corporation shareholders, and 10,872,400 shares of Common Stock reserved for issuance
in connection with certain Abpro Corporation rollover RSUs and stock options (collectively, the &#8220;<b>Merger Consideration</b>&#8221;).
In addition, New Abpro issued an aggregate of 3,367,401 shares of Common Stock to the PIPE investors in connection with the PIPE Offering,
an aggregate of 1,282,852 Vendor Shares to various vendors in connection with the Closing, and Sponsor forfeited and New Abpro cancelled

Securityholders named in this prospectus or their permitted transferees, may resell from time to time up to 31,785,312 shares of Common
Stock and 13,850,000 Placement Warrants. We are registering the offer and sale of these securities to satisfy certain registration rights
we have granted. The Selling Securityholders may offer, sell or distribute all or a portion of the securities hereby registered publicly
or through private transactions at prevailing market prices or at negotiated prices. We will not receive any of the proceeds from such
sales of our Common Stock or Placement Warrants, except with respect to amounts received by us upon the exercise of the Placement Warrants.
We will bear all costs, expenses and fees in connection with the registration of these securities, including with regard to compliance
with state securities or &#8220;blue sky&#8221; laws. The Selling Securityholders will bear all commissions and discounts, if any, attributable
to their sale of Common Stock or Warrants. See section entitled &#8220;<i>Plan of Distribution</i>&#8221; beginning on page&#160;150 of

that the warrant holders will exercise their Warrants, and therefore the amount of cash proceeds that we would receive is, among other
things, dependent upon the market price of our Common Stock. If the market price for our Common Stock is less than the exercise price
of $11.50, subject to adjustment as described herein, we believe such holders will be unlikely to exercise their Warrants, as applicable,

a substantial percentage of our public float and of our outstanding Common Stock. The number of shares being registered in this prospectus
(which include shares issuable upon exercise of the Warrants and shares issuable pursuant to the SEPA) represents approximately 117.0%
of the total Common Stock outstanding as of December 23, 2024, which was 51,815,765 shares of Common Stock. In addition, the securities
beneficially owned by the Sponsor represent approximately 6.7% of the total Common Stock outstanding, and this holder will have the ability
to sell all of its shares pursuant to the registration statement of which this prospectus forms a part so long as it is available for
use and the six month lockup period has expired. The sale of the securities being registered in this prospectus, or the perception in
the market that such sales may occur, could result in a significant decline in the public trading price of our Common Stock.</p><div>

by the Selling Securityholders for nominal consideration or purchased for prices considerably below the Business Combination price and
the current market price of the Common Stock. Even though the current market price is significantly below the price at the time of the
ACAB IPO, certain Selling Securityholders have an incentive to sell because they will still profit on sales due to the lower price at
which they acquired their shares as compared to the public investors. In particular, the Sponsor may experience a positive rate of return
on the securities it purchased due to the differences in the purchase prices described above, to the extent they acquired such securities
for less than the relevant trading price, and the public securityholders may not experience a similar rate of return on the securities
they purchased due to the differences in the purchase prices described above. Based on the last reported sale price of Common Stock referenced
below, shares acquired for less than such last reported sale price, the Selling Securityholders may experience potential profit up to
$1.49 per share.</p><div>

company dedicated to developing next-generation antibody therapeutics with the goal of improving the lives of patients with severe and
life-threatening diseases. New Abpro is focused on novel antibody constructs for immuno-oncology and ophthalmology. By leveraging its
proprietary DiversImmune&#174; and MultiMab<sup>TM</sup> antibody discovery and engineering platforms, New Abpro is developing a pipeline

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">On November 13, 2024, ACAB
completed a series of transactions that resulted in the combination (the &#8220;<b>Business Combination</b>&#8221;) of ACAB with Abpro
Corporation pursuant to the previously announced Business Combination Agreement, dated December 11, 2023, amended by an amendment dated
September 4, 2024 (the &#8220;<b>BCA</b>&#8221;), by and among ACAB, Abpro Merger Sub Corp., a Delaware corporation and a wholly owned
subsidiary of ACAB (&#8220;<b>Merger Sub</b>&#8221;), and Abpro Corporation (the &#8220;<b>Closing</b>&#8221;), following the approval
at the special meeting of the shareholders of ACAB held on November 7, 2024 (the &#8220;<b>Special Meeting</b>&#8221;). On November 12,
2024, pursuant to the BCA, and as described in greater detail in the Company&#8217;s final prospectus and definitive proxy statement,
which was filed with the U.S. Securities and Exchange Commission (the &#8220;<b>SEC</b>&#8221;) on October 18, 2024 (the &#8220;<b>Proxy
Statement/Prospectus</b>&#8221;), Merger Sub merged with and into Abpro Corporation, with Abpro Corporation surviving the merger as a
wholly owned subsidiary of ACAB, and ACAB changed its name to Abpro Holdings, Inc. As consideration for the Business Combination, New
Abpro issued to or reserved for Abpro Corporation shareholders an aggregate of approximately 50,000,000 shares of Common Stock, consisting
of 39,123,200 shares of Common Stock issued to Abpro Corporation shareholders, and 10,872,400 shares of Common Stock reserved for issuance
in connection with certain Abpro Corporation rollover RSUs and stock options (collectively, the &#8220;<b>Merger Consideration</b>&#8221;).
In addition, New Abpro issued an aggregate of 3,367,401 shares of Common Stock to the PIPE investors in connection with the PIPE Offering,
an aggregate of 1,282,852 Vendor Shares to various vendors in connection with the Closing, and Sponsor forfeited and New Abpro cancelled
966,442 shares of Common Stock.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Simultaneous with the Closing,
New Abpro also completed its previously announced private investment in public equity, issuing 1,122,467 shares of Common Stock and 2,244,934
Incentive Shares in the PIPE Offering, which raised $7.0 million in net proceeds.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&#160;</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Our Common Stock and our Public
Warrants are listed on the Nasdaq Global Market under the symbols &#8220;ABP&#8221; and &#8220;ABPWW,&#8221; respectively. On December
20, 2024, the closing price of our Common Stock was $2.07 and the closing price for our Public Warrants was $0.10.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">There is no assurance that
the holders of the Warrants will elect to exercise any or all of the Warrants, which could impact our liquidity position. To the extent
that the Warrants are exercised on a &#8220;cashless basis,&#8221; the amount of cash we would receive from the exercise of the Warrants
will decrease. We believe the likelihood that Warrant holders will exercise their Warrants, and therefore the amount of cash proceeds
that we would receive is, among other things, dependent upon the market price of our Common Stock. If the market price for our Common
Stock is less than the applicable exercise price of $11.50, subject to adjustment as described herein, we believe such holders will be
unlikely to exercise their Warrants. Based on our current operating plan, our existing cash and cash equivalents, together with the proceeds
from the Business Combination and the PIPE Offering, will be insufficient to meet our anticipated cash needs for working capital, financial

a lack of financing commitments to meet cash requirements, and is subject to our ability to generate a profit or obtain appropriate financing
from outside sources, including obtaining additional funding from the sale of our securities or obtaining loans from third parties where
possible. We will need to raise additional capital to fund our operations and drug development. We cannot assure you that we will be
able to raise additional capital on commercially reasonable terms or at all. The perception that we may not be able to continue as a
going concern may materially limit our ability to raise additional funds through the issuance of new debt or equity securities or otherwise
and no assurance can be given that sufficient funding will be available when needed to allow us to continue as a going concern. This
perception may also make it more difficult to operate our business due to concerns about our ability to meet our contractual obligations.
If we cannot continue as a going concern, we may have to liquidate our assets and may receive less than the value at which those assets
are carried on our financial statements, and it is likely that our stockholders may lose some or all of their investment in us.</p><div>

$11.7&#160;million, respectively. Substantially all of our losses have resulted from expenses incurred in connection with our collaboration
agreements, research and development programs and from general and administrative costs associated with our operations. We continue to

trials are long, expensive and unpredictable processes that can be subject to extensive delays. We cannot guarantee that any clinical
trials will be conducted as planned or completed on schedule, if at all. It may take several years and require significant expenditures
to complete the preclinical studies and clinical trials necessary to commercialize a product candidate, and delays or failure are inherently
unpredictable and can occur at any stage. We may also be required to conduct additional clinical trials or other testing of our product
candidates beyond the trials and testing that we contemplate, which may lead to us incurring additional unplanned costs or result in
delays in clinical development. In addition, we may be required to redesign or otherwise modify our plans with respect to an ongoing
or planned clinical trial, and changing the design of a clinical trial can be expensive and time consuming. An unfavorable outcome in
one or more trials would be a major setback for our product candidates and for us. An unfavorable outcome in one or more trials may require
us to delay, reduce the scope of or eliminate one or more product development programs, which could have a material adverse effect on
our business, financial position, results of operations and future growth prospects.</p><div>

in early stages of development, and we are subject to the risks of failure inherent in the development of product candidates based on
novel technologies. We believe that we are at a sufficiently mature development stage with both lead candidates that given adequate funding
and, in the case of ABP-102, continued successful collaboration with Celltrion, these programs would be able to enter clinical trials
in 2026 (in the case of ABP-102 and ABP-201). However, there can be no guarantee that both or either will do so, and to date, we have
not yet had any discussions with the U.S. Food and Drug Administration (the &#8220;FDA&#8221;) regarding the clinical trial design for
our lead product candidates. We have never generated any revenue from product sales, and have not obtained regulatory approval for any
of our product candidates. Accordingly, you should consider our prospects in light of the costs, uncertainties, delays, and difficulties
frequently encountered by preclinical stage biopharmaceutical companies such as ours. We currently do not expect to generate any near-term
revenue other than from certain milestone payments under the collaboration agreements relating to our two lead antibodies. We do not
expect to generate any revenue from product sales for the foreseeable future, and we expect to continue to incur significant operating
losses for the foreseeable future due to the cost of research and development, preclinical studies and clinical trials, and the regulatory
approval process for our product candidates. We expect our net losses to increase substantially as we enter into clinical development
of our lead programs. However, the amount of our future losses is uncertain. Our ability to achieve profitability, if ever, will depend
on, among other things, our, and our existing or future partners, successfully developing product candidates, obtaining regulatory approvals
to market and commercialize product candidates, achieving contractual milestones under our collaboration agreements, manufacturing any
approved products on commercially reasonable terms, realizing royalties on any approved products under our collaboration agreements,
establishing a sales and marketing organization or suitable third-party alternatives for any approved product and raising sufficient
funds to finance business activities. If we, and our existing or future partners, are unable to develop our technologies and commercialize
one or more of our product candidates or if sales revenue from any product candidate that receives approval is insufficient, we will
not achieve profitability, which will have a material and adverse effect on our business, financial condition, results of operations
and prospects. Any predictions you make about our future success or viability may not be as accurate as they could be if we had a history
of successfully developing and commercializing pharmaceutical products.</p><div>

half-life resulting in reduced dosing required. For example, when administered in a human, we may find that our product candidates perform
differently than in preclinical studies. We currently have only limited preclinical data, and no conclusive evidence, to suggest that
we can introduce these favorable properties into any of our product candidates. We may spend substantial funds attempting to introduce
these properties and may never succeed in doing so. In addition, certain of our product candidates may demonstrate different chemical
and pharmacological properties in patients than they do in laboratory studies. Although certain of our product candidates have successful
results in animal studies, they may not demonstrate the same chemical and pharmacological properties in humans and may interact with
human biological systems in unforeseen, ineffective or harmful ways. As a result, we may never succeed in developing a marketable product,

antibody-based therapeutics, which may increase the complexity, uncertainty and length of the regulatory approval process for our product
candidates. For example, the FDA may require us to provide additional data to support our regulatory applications. We and our existing
or future partners may never receive approval to market and commercialize any product candidate. Even if we or an existing or future
partner obtains regulatory approval, the approval may be for targets, disease indications or patient populations that are not as broad
as we intended or desired or may require labeling that includes significant use or distribution restrictions or safety warnings. We or
an existing or future partner may be subject to post-marketing testing requirements to maintain regulatory approval. If any of our product
candidates prove to be ineffective, unsafe or commercially unviable, our entire pipeline could have little, if any, value, which could
require us to change our focus, approach to antibody development and reengineer the antibody. Any of these events could have a material

relinquish rights to some of our technologies or product candidates that we would otherwise pursue on our own. We do not expect to realize
revenue from sales of products or royalties from licensed products in the foreseeable future, if at all, and unless and until our product
candidates are clinically tested, approved for commercialization and successfully marketed. To date, we have primarily financed our operations
through the sale of debt and equity securities and payments received under our collaboration agreements. We will be required to seek
additional funding in the future and currently intend to do so through additional collaborations, public or private equity offerings
or debt financings, credit or loan facilities or a combination of one or more of these funding sources. Our ability to raise additional
funds will depend on financial, economic and other factors, many of which are beyond our control. Additional funds may not be available
to us on acceptable terms or at all. If we raise additional funds by issuing equity securities, our stockholders will suffer dilution
and the terms of any financing may adversely affect the rights of our stockholders. In addition, as a condition to providing additional
funds to us, future investors may demand, and may be granted, rights superior to those of existing stockholders. Debt financing, if available,
is likely to involve restrictive covenants limiting our flexibility in conducting future business activities, and, in the event of insolvency,
debt holders would be repaid before holders of our equity securities received any distribution of our corporate assets.</p><div>

consider strategic transactions, such as additional collaborations, acquisitions of companies, asset purchases, joint ventures and&#160;out-&#160;or&#160;in-licensing&#160;of

including with major biotechnology or biopharmaceutical companies or hospitals. The competition for partners is intense, and the negotiation
process is time-consuming and complex. Any new collaboration may be on terms that are not optimal for us, and we may not be able to maintain
any new collaboration if, for example, development or approval of a product candidate is delayed, sales of an approved product candidate
do not meet expectations or the partner terminates the collaboration. Any such collaboration, or other strategic transaction, may require
us to incur&#160;non-recurring&#160;or other charges, increase our near- and long-term expenditures and pose significant integration
or implementation challenges or disrupt our management or business. These transactions would entail numerous operational and financial
risks, including:</p><div>

of drugs and therapeutic biologics is highly competitive. We compete with a variety of multinational biopharmaceutical companies and
specialized biotechnology companies, as well as technology being developed at universities and other research institutions. Our competitors
are often larger and better funded. Our competitors have developed, are developing or will develop product candidates and processes competitive
with our product candidates and processes. Competitive therapeutic treatments include those that have already been approved and accepted
by the medical community and any new treatments that are currently in development or that enter the market. We believe that a significant
number of products are currently under development, and may become commercially available in the future, for the treatment of conditions
for which we may try to develop product candidates. There is intense and rapidly evolving competition in the biotechnology, biopharmaceutical
and antibody and immunoregulatory therapeutics fields. We believe that while our&#160;<i>DiversImmune<sup>&#174;</sup></i>&#160;and&#160;<i>MultiMab<sup>TM</sup></i>&#160;platforms,
their associated intellectual property, the characteristics of our antibody product candidates in development, and our scientific and
technical&#160;know-how&#160;give us a competitive advantage in this space, competition from many sources remains. Given the number of
competitors, we strive to differentiate ourselves from them and contrast the perceived advantages of our technologies and product candidates.
There is a risk that some of our competitors will take issue with our positioning and make allegations regarding our company or our business
practices. Any such allegations could divert management&#8217;s attention, which could have an adverse effect on our business.</p><div>

containment measures. Political, economic and regulatory developments may further complicate pricing negotiations, and pricing negotiations
may continue after reimbursement has been obtained. Reference pricing used by various European Union member states and parallel distribution,
or arbitrage between&#160;low-priced&#160;and high-priced member states, can further reduce prices. In some countries, we or future partners

companies are generally uncertain because they involve complex legal and factual considerations and have, in recent years, been the subject
of much legislation and litigation. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights
are highly uncertain. The standards applied by the United States Patent and Trademark Office, or USPTO, and foreign patent offices in
granting patents are not always applied uniformly or predictably. For example, there is no uniform worldwide policy regarding patentable
subject matter or the scope of claims allowable in patents. In addition, changes in either the patent laws or interpretation of the patent
laws in the United States and other countries may diminish the value of our owned or&#160;in-licensed&#160;patents or narrow the scope
of our patent protection. Publications of discoveries in scientific literature often lag behind the actual discoveries and patent applications
in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore,
we cannot know with certainty whether we or our licensors were the first to make the inventions claimed in our owned or&#160;in-licensed&#160;patents
or pending applications, or that we or our licensors were the first to file for patent protection of such inventions. There is no assurance
that all potentially relevant prior art relating to our owned or&#160;in-licensed&#160;patents and patent applications has been found.
We may be unaware of prior art that could be used to invalidate an issued patent or prevent our owned or&#160;in-licensed&#160;pending

or the issuance of a patent is not conclusive as to its ownership, inventorship, scope, patentability, validity, or enforceability, and
patents and patent applications may be challenged in the courts in the patent office in the Unites States and abroad. For example, we
or our licensors may be subject to a third-party&#160;pre-issuance&#160;submission of prior art to the USPTO or become involved in opposition,
derivation, reexamination, inter partes review, post-grant review, or interference proceedings, declaratory judgment actions or counterclaims
challenging our owned or&#160;in-licensed&#160;patent rights or the rights of others. An adverse determination in any such submission,
proceeding, or litigation could prevent the issuance of, reduce the scope of, invalidate, or render unenforceable our owned or&#160;in-licensed&#160;patent
rights, limit our ability to stop others from using or commercializing similar or identical platforms and products, allow third parties
to compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing
third-party patent rights. In addition, if the breadth or strength of protection provided by our owned or&#160;in-licensed patents and
patent applications is threatened, it could dissuade companies from collaborating with us to license, develop, or commercialize current
or future platforms or product candidates. Any of the foregoing could have a material adverse effect on our business, financial condition,

ABP-110 from the National Cancer Institute, or NCI, a division of the National Institutes of Health, or NIH. As a result, the U.S. government
may have certain rights, including&#160;so-called&#160;march-in&#160;rights, to such patent rights and any products or technology developed
from such patent rights. When new technologies are developed with U.S. government funding, the U.S. government generally obtains certain
rights in any resulting patents, including a&#160;non-exclusive&#160;license authorizing the U.S. government to use the invention for&#160;non-commercial&#160;purposes.
These rights may permit the U.S. government to disclose our confidential information to third parties and to exercise&#160;march-in&#160;rights
to use or allow third parties to use our licensed technology. The U.S. government can exercise its&#160;march-in&#160;rights if it determines
that action is necessary because we fail to achieve the practical application of government-funded technology, because action is necessary
to alleviate health or safety needs, to meet requirements of federal regulations, or to give preference to U.S. industry. In addition,
our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in the United
States. Any exercise by the U.S. government of such rights could harm our competitive position, business, financial condition, results
of operations, and prospects.</p><div>

to impose, various development, commercialization, funding, milestone, royalty, diligence, sublicensing, insurance, patent prosecution

MSK. MSK has demanded payments totaling approximately $1.2&#160;million. We have contacted MSK about possible settlement and have responded
to a counterproposal received from MSK in February 2024, and are continuing discussions. See &#8220;<i>Legal Proceedings</i>&#8221; for

Our breach of this license agreement or breach of any other license agreement, or the use of intellectual property licensed to us in

maintained, enforced, and defended in a manner consistent with the best interests of our business. If our licensors fail to prosecute,
maintain, enforce, and defend such patents, or lose rights to those patents or patent applications, the rights we have licensed may be

while we cannot currently determine the amount of the royalty obligations we would be required to pay on sales of future products, if
any, the amounts may be significant. The amount of our future royalty obligations will depend on the technology and intellectual property

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Patents have a limited lifespan.
In the United States, the standard expiration of a patent is generally 20 years after it is filed. Various extensions may be available.
However, the life of a patent and the protection it affords is limited. As a result, our owned and&#160;in-licensed&#160;patent portfolio
may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours. For example,
given the large amount of time required for the research, development, testing and regulatory review of new product candidates, patents
protecting such candidates might expire before or shortly after such candidates are commercialized. In the United States, the Drug Price
Competition and Patent Term Restoration Act of 1984 permits a patent term extension of up to five years beyond the normal expiration
of the patent, which is limited to the approved indication (or any additional indications approved during the period of extension). Additionally,
a patent term extension cannot extend the remaining term of a patent beyond 14 years from the date of product approval, only one patent
may be extended and only those claims covering the approved drug, a method for using it, or a method for manufacturing it may be extended.
However, the applicable authorities, including the FDA and the USPTO in the United States, and any equivalent regulatory authority in
other countries, may not agree with our assessment of whether such extensions are available, and may refuse to grant extensions to our
patents, or may grant more limited extensions than we request. An extension may not be granted or may be limited because of, for example
a failure to exercise due diligence during the testing phase or regulatory review process, failing to apply within applicable deadlines,
failing to apply prior to expiration of relevant patents, or otherwise failing to satisfy applicable requirements. If this occurs, our
competitors may be able to take advantage of our investment in development and clinical trials by referencing our clinical and preclinical
data and launch their product earlier than might otherwise be the case, which could have a material adverse effect on our business, financial
condition, results of operations and prospects.</p><div>

laws or interpretation of the patent laws in the United States could increase the uncertainties and costs surrounding the prosecution
of patent applications and the enforcement or defense of issued patents. The United States has recently enacted and implemented wide-ranging
patent reform legislation. On September&#160;16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law,
which could increase the uncertainties and costs surrounding the prosecution of our owned or&#160;in-licensed&#160;patent applications
and the enforcement or defense of our owned or&#160;in-licensed&#160;issued patents. The Leahy-Smith Act includes a number of significant
changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted, redefine prior art, may
affect patent litigation and switch the U.S. patent system from a&#160;&#8220;first-to-invent&#8221;&#160;system to a&#160;&#8220;first-to-file&#8221;&#160;system.
Under a&#160;first-to-file&#160;system, assuming the other requirements for patentability are met, the first inventor to file a patent
application generally will be entitled to the patent on an invention regardless of whether another inventor had made the invention earlier.
These provisions also allow third-party submission of prior art to the USPTO during patent prosecution and set forth additional procedures
to challenge the validity of a patent by the USPTO administered post grant proceedings, including derivation, reexamination, inter partes
review, post-grant review, and interference proceedings. The USPTO developed additional regulations and procedures to govern administration
of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and, in particular, the&#160;first-to-file&#160;provisions,
only became effective on March&#160;16, 2013. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the
operation of our business. The Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution
of our owned or&#160;in-licensed&#160;patent applications and the enforcement or defense of our issued owned or&#160;in-licensed&#160;patents,
all of which could have a material adverse effect on our business, financial condition, results of operations and prospects.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The U.S. Supreme Court has
ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or
weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our and our licensors&#8217;
ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once
obtained. The recent decision by the Supreme Court in Association for Molecular Pathology v. Myriad Genetics, Inc. precludes claims directed
to a nucleic acid having a stated nucleotide sequence that is identical to a sequence found in nature and that is unmodified. This decision
has yet to be clearly interpreted by other courts and by the USPTO. We cannot assure you that the interpretations of this decision or
that subsequent rulings will not adversely impact our owned or&#160;in-licensed&#160;patents or patent applications. Depending on decisions
by the U.S. Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways
that would weaken our and our licensors&#8217; ability to obtain new patents or to enforce our existing owned or&#160;in-licensed&#160;patents
and patents that we might obtain or&#160;in-license&#160;in the future. Similarly, changes in patent law and regulations in other countries
or jurisdictions or changes in the governmental bodies that enforce them or changes in how the relevant governmental authority enforces
patent laws or regulations may have a material adverse effect on our and our licensors&#8217; ability to obtain new patents or to protect
and enforce our owned or&#160;in-licensed&#160;patents or that we may obtain or&#160;in-license&#160;in the future.</p><div>

protection, particularly those relating to biotechnology, which could make it difficult for us to stop the infringement of our owned

generally. Proceedings to enforce our owned or&#160;in-licensed&#160;intellectual property and proprietary rights in foreign jurisdictions

may find it necessary to pursue claims or initiate lawsuits to protect or enforce our owned or&#160;in-licensed&#160;patent or other
intellectual property rights. The cost to us in defending or initiating any litigation or other proceeding relating to our owned or&#160;in-licensed&#160;patent
or other intellectual property rights, even if resolved in our favor, could be substantial, and any litigation or other proceeding would
divert our management&#8217;s attention. Such litigation or proceedings could materially increase our operating losses and reduce the
resources available for development activities or any future sales, marketing or distribution activities. Some of our competitors may
be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources.
Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could delay our research and development
efforts and materially limit our ability to continue our operations. Furthermore, because of the substantial amount of discovery required
in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by
disclosure during this type of litigation. In addition, there could be public announcements of the results of hearings, motions or other
interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a material
adverse effect on the price of our common stock.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">If we or our licensors were
to initiate legal proceedings against a third party to enforce a patent covering one of our product candidates or our technology, the
defendant could counterclaim that such patent is invalid or unenforceable. In patent litigation in the United States, defendant counterclaims
alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of
several statutory requirements, for example, lack of novelty, indefiniteness, lack of written description, obviousness or&#160;non-enablement.&#160;Grounds
for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information
from the USPTO, or made a misleading statement, during prosecution. The outcome following legal assertions of invalidity and unenforceability
during patent litigation is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no
invalidating prior art, of which we or our licensors and the patent examiner were unaware during prosecution. If a defendant were to
prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection
on one or more of our product candidates or certain aspects of our platform technology. Such a loss of patent protection could have a
material adverse effect on our business, financial condition, results of operations and prospects. Patents and other intellectual property
rights also will not protect our product candidates and technologies if competitors or third parties design around such product candidates
and technologies without legally infringing, misappropriating or violating our owned or&#160;in-licensed&#160;patents or other intellectual
property rights.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Because the antibody landscape
is still evolving, it is difficult to conclusively assess our freedom to operate without infringing, misappropriating or violating third-party
rights. There are numerous companies that have pending patent applications and issued patents broadly covering antibodies generally or
covering antibodies directed against the same targets as, or targets similar to, those we are pursuing. Our competitive position may
materially suffer if patents issued to third parties or other third-party intellectual property rights cover our current or future technologies
or product candidates or elements thereof, or our manufacture or uses relevant to our development plans. In such cases, we may not be
in a position to develop or commercialize current or future technologies or product candidates unless we successfully pursue litigation
to nullify or invalidate the third-party intellectual property right concerned, or enter into a license agreement with the intellectual
property right holder, if available on commercially reasonable terms. There may be issued patents of which we are not aware, held by
third parties that, if found to be valid and enforceable, could be alleged to be infringed by our current or future technologies or product
candidates. There also may be pending patent applications of which we are not aware that may result in issued patents, which could be
alleged to be infringed by our current or future technologies or product candidates. If such an infringement claim should be brought
and be successful, we may be required to pay substantial damages, be forced to abandon our current or future technologies or product
candidates or seek a license from any patent holders. No assurances can be given that a license will be available on commercially reasonable
terms, if at all.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">It is also possible that
we have failed to identify relevant third-party patents or applications. For example, U.S. applications filed before November&#160;29,
2000 and certain U.S. applications filed after that date that will not be filed outside the U.S. remain confidential until patents issue.
Patent applications in the United States and elsewhere are published approximately 18 months after the earliest filing for which priority
is claimed, with such earliest filing date being commonly referred to as the priority date. Therefore, patent applications covering our
product candidates or platform technologies could have been filed by others without our knowledge. Additionally, pending patent applications
that have been published can, subject to certain limitations, be later amended in a manner that could cover our platforms, our product
candidates or the use of our technologies. Third-party intellectual property right holders may also actively bring infringement, misappropriation
or violation claims against us. We cannot guarantee that we will be able to successfully settle or otherwise resolve such claims. If
we are unable to successfully settle future claims on terms acceptable to us, we may be required to engage in or continue costly, unpredictable
and time-consuming litigation and may be prevented from or experience substantial delays in marketing our product candidates. If we fail
in any such dispute, in addition to being forced to pay damages, we may be temporarily or permanently prohibited from commercializing
any of our current or future technologies or product candidates that are held to be infringing, misappropriating or violating. We might,
if possible, also be forced to redesign current or future technologies or product candidates so that we no longer infringe, misappropriate
or violate the third-party intellectual property rights. Any of these events, even if we were ultimately to prevail, could require us
to divert substantial financial and management resources that we would otherwise be able to devote to our business, which could have
a material adverse effect on our business, financial condition, results of operations and prospects.</p><div>

confidential and unpatented&#160;know-how,&#160;important to the maintenance of our competitive position. However, trade secrets and&#160;know-how&#160;can
be difficult to protect. We protect trade secrets and confidential and unpatented&#160;know-how,&#160;in part, by entering into&#160;non-disclosure&#160;and
confidentiality agreements with parties who have access to such knowledge, such as our employees, corporate collaborators, outside scientific
collaborators, CROs, contract manufacturers, consultants, advisors and other third parties. We also enter into confidentiality and invention
or patent assignment agreements with our employees and consultants that obligate them to maintain confidentiality and assign their inventions
to us. Despite these efforts, any of these parties may breach such agreements and disclose our proprietary information, including our
trade secrets, and we may not be able to obtain adequate remedies for such breaches. We may also become involved in inventorship disputes
relating to inventions and patents developed by our employees or consultants under such agreements. Enforcing a claim that a party illegally
disclosed or misappropriated a trade secret, or securing title to an employee-or consultant-developed invention if a dispute arises,
is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts in the United States and certain
foreign jurisdictions are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained
or independently developed by a competitor, we would have no right to prevent them from using that technology or information to compete
with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would

early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials. Product candidates
in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical

approval, recordkeeping, reporting, labeling, storage, packaging, advertising and promotion, pricing, marketing and distribution of drugs
and therapeutic biologics. Rigorous preclinical testing and clinical trials and an extensive regulatory approval process are required
to be successfully completed in the U.S. and in many foreign jurisdictions before a new drug or therapeutic biologic can be marketed.
Satisfaction of these and other regulatory requirements is costly, time consuming, uncertain and subject to unanticipated delays. It
is possible that none of the product candidates we may develop will obtain the regulatory approvals necessary for us or our existing

obtain regulatory approvals, including approval by the FDA. The time required to obtain FDA and other approvals is unpredictable but
typically takes many years following the commencement of clinical trials, depending upon the type, complexity and novelty of the product
candidate. The standards that the FDA and its foreign counterparts use when regulating us require judgment and can change, which makes
it difficult to predict with certainty how they will be applied. Any analysis we perform of data from preclinical and clinical activities
is subject to confirmation and interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. We
may also encounter unexpected delays or increased costs due to new government regulations, for example, from future legislation or administrative
action, or from changes in FDA policy during the period of product development, clinical trials and FDA regulatory review. It is impossible

filing for orphan drug designation if and where available for our product candidates. Under the Orphan Drug Act, the FDA may grant orphan
drug designation to a drug or biologic intended to treat a rare disease or condition, which is defined as one occurring in a patient
population of fewer than 200,000 in the United States, or a patient population greater than 200,000 in the United States where there
is no reasonable expectation that the cost of developing the drug or biologic will be recovered from sales in the United States. In the
United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical
trial costs, tax advantages and&#160;user-fee&#160;exemptions. In addition, if a product that has orphan drug designation subsequently
receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan drug exclusivity,
which means that the FDA may not approve any other applications, including a full NDA or BLA, to market the same drug or biologic for
the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan
drug exclusivity or where the original manufacturer is unable to assure sufficient product quantity.</p><div>

for our lead product candidates&#160;ABP-102&#160;and&#160;ABP-201.&#160;However, while we may seek orphan drug designations for our
product candidates, we may never receive such designations. In addition, orphan drug designation neither shortens the development time
or regulatory review time of a drug, nor gives the drug any advantage in the regulatory review or approval process. Even if we obtain
such designations, we may not be the first to obtain regulatory approval of a product candidate for the orphan-designated indication
due to the uncertainties associated with developing pharmaceutical products. We may also fail to meet requirements to maintain orphan
drug designation while developing&#160;ABP-102&#160;and&#160;ABP-201.&#160;In addition, exclusive marketing rights in the United States
may be limited if we decide to seek approval for an indication broader than the orphan-designated indication or may be lost if the FDA
later determines that the request for designation was materially defective or if we are unable to assure sufficient quantities of the
product to meet the needs of patients with the orphan-designated disease or condition. Further, even if we obtain orphan drug exclusivity
for a product, that exclusivity may not effectively protect the product from competition because different drugs with different active
moieties may receive and be approved for the same condition, and only the first applicant to receive approval will receive the benefits
of marketing exclusivity. Even after an orphan-designated product is approved, the FDA can subsequently approve a later drug with the
same active moiety for the same condition if the FDA concludes that the later drug is clinically superior if it is shown to be safer,
more effective or makes a major contribution to patient care.</p><div>

provisions of the Federal Food, Drug, and Cosmetic Act (the &#8220;FDCA&#8221;), and the FDA&#8217;s implementing regulations, the FDA
may grant accelerated approval to a product designed to treat a serious or life-threatening condition that provides meaningful therapeutic
advantage over available therapies and demonstrates an effect on a surrogate endpoint or intermediate clinical endpoint that is reasonably
likely to predict clinical benefit. The FDA considers a clinical benefit to be a positive therapeutic effect that is clinically meaningful
in the context of a given disease. For the purposes of accelerated approval, a surrogate endpoint is a marker, such as a laboratory measurement,
radiographic image, physical sign, or other measure that is thought to predict clinical benefit, but is not itself a measure of clinical
benefit. An intermediate clinical endpoint is a clinical endpoint that can be measured earlier than an effect on irreversible morbidity
or mortality that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit. The accelerated
approval development pathway may be used in cases in which the advantage of a new drug over available therapy may not be a direct therapeutic
advantage, but is a clinically important improvement from a patient and public health perspective. If granted, accelerated approval is
contingent on the sponsor&#8217;s agreement to conduct, in a diligent manner, additional post-approval confirmatory studies to verify
and describe the drug&#8217;s clinical profile or risks and benefits for accelerated approval. The FDA may require that any such confirmatory
study be initiated or substantially underway prior to the submission of an application for accelerated approval. If such post-approval
studies fail to confirm the drug&#8217;s clinical profile or risks and benefits, the FDA may withdraw its approval of the drug.</p><div>

have been judicial, Congressional and executive challenges to certain aspects of the ACA. On June&#160;17, 2021, the U.S. Supreme Court
dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality
of the ACA. Prior to the Supreme Court&#8217;s decision, President Biden issued an executive order to initiate a special enrollment period
from February&#160;15, 2021 through August&#160;15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace.
The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit
access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements,
and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear
how other healthcare reform measures of the Biden administration or other efforts, if any, to challenge, repeal or replace the ACA will
impact our business. Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. The Budget
Control Act of 2011 and subsequent legislation, among other things, created measures for spending reductions that resulted in aggregate
reductions of Medicare payments to providers up to 2% per fiscal year, which, due to subsequent legislative amendments, will remain in
effect through 2030 unless additional Congressional action is taken.</p><div>

for Medicare Part D beneficiaries, the imposition of new manufacturer financial liability on most drugs in Medicare Part D, permitting
the U.S. government to negotiate Medicare Part B and Part D pricing for certain high-cost drugs and biologics without generic or biosimilar
competition, requiring companies to pay rebates to Medicare for drug prices that increase faster than inflation, and delaying the rebate
rule that would require pass through of pharmacy benefit manager rebates to beneficiaries. In August 2023, the government selected the
first 10 drugs to be put through the Medicare drug price negotiation program, which is currently subject to several constitutional challenges.
The outcomes of these challenges on the IRA, and the effect of the IRA on our business and the healthcare industry in general, are not

and reform government program reimbursement methodologies for drugs. The U.S. Department of Health and Hman Services (&#8220;HHS&#8221;)

the U.S. pharmaceutical industry. The ACA, among other things, subjected therapeutic biologics to potential competition by lower-cost
biosimilars, addressed a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated
for drugs and therapeutic biologics that are inhaled, infused, instilled, implanted or injected, increased the minimum Medicaid rebates
owed by manufacturers under the Medicaid Drug Rebate Program, extended the rebate program to individuals enrolled in Medicaid managed

of the ACA have yet to be fully implemented and certain provisions have been subject to judicial and Congressional challenges, as well
as efforts by the Trump Administration to repeal or replace certain aspects of the ACA. For example, since January 2017, President Trump
has signed two executive orders and other directives designed to delay, circumvent, or loosen certain requirements mandated by the ACA.
Concurrently, Congress has considered legislation that would repeal or repeal and replace all or part of the ACA. On December&#160;20,
2017, Congress passed The Tax Cuts and Jobs Act, which includes a provision repealing the individual mandate under the ACA, effective
January&#160;1, 2019. We continue to evaluate how the ACA and recent efforts to repeal and replace or limit the implementation of the
ACA will impact our business.</p><div>

changes have been proposed and adopted in the United States since the ACA was enacted. On August&#160;2, 2011, the Budget Control Act
of 2011 among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked
with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required
goals, thereby triggering the legislation&#8217;s automatic reduction to several government programs. This includes aggregate reductions
of Medicare payments to providers of 2% per fiscal year. These reductions went into effect on April&#160;1, 2013 and, due to subsequent
legislative amendments to the statute, will remain in effect through 2024 unless additional Congressional action is taken. On January&#160;2,
2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several
types of providers. Additionally, there has been heightened governmental scrutiny recently over the manner in which manufacturers set
prices for their marketed products. For example, there have been several recent Congressional inquiries and proposed and enacted federal
and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing
and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. These new laws and initiatives
may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on our future
customers and accordingly, our financial operations.</p><div>

treatments will be available from third-party payors, such as government authorities, private health insurers, and health maintenance
organizations. Patients who are prescribed medications for the treatment of their conditions generally rely on third-party payors to
reimburse all or part of the costs associated with their prescription drugs. Coverage and adequate reimbursement from government healthcare
programs, such as Medicare and Medicaid, and private health insurers are critical to new product acceptance. Patients are unlikely to
use our future product candidates unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost
of our product candidates.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Cost-containment is a priority
in the U.S. healthcare industry and elsewhere. As a result, government authorities and other third-party payors have attempted to control
costs by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring
that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products.
Third-party payors also may request additional clinical evidence beyond the data required to obtain marketing approval, requiring a company
to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of its product. We
cannot be sure that coverage and adequate reimbursement will be available for any product that we commercialize and, if reimbursement
is available, that the level of reimbursement will be adequate. Coverage and reimbursement may impact the demand for, or the price of,
any product candidate for which we obtain marketing approval. If coverage and reimbursement are not available or are available only at
limited levels, we may not be able to successfully commercialize any product candidate for which we obtain marketing approval.</p><div>

that govern regulatory approvals, pricing and reimbursement for new drugs and therapeutic biologics vary widely from country to country.
Some countries require approval of the sale price of a drug or therapeutic biologic before it can be marketed. In many countries, the
pricing review period begins after marketing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains
subject to continuing governmental control even after initial approval is granted. As a result, we might obtain regulatory approval for
a product in a particular country, but then be subject to price regulations that delay our commercial launch of the product, possibly
for lengthy time periods and negatively impact the revenues we are able to generate from the sale of the product in that country. Adverse
pricing limitations may hinder our ability to recoup our investment in one or more product candidates, even if our product candidates
obtain regulatory approval.</p><div>

We will adopt a Code of Business Conduct and Ethics, which will be effective upon the Closing of the Business Combination, and expect

compliance with the FCPA and other anti-corruption laws applicable to our business throughout the world. However, we cannot assure you
that our employees and third-party intermediaries will comply with this code or such anti-corruption laws. Noncompliance with anti-corruption

other collateral consequences. If any subpoenas, investigations, or other enforcement actions are launched, or governmental or other
sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations and
financial condition could be materially harmed. In addition, responding to any action will likely result in a materially significant
diversion of management&#8217;s attention and resources and significant defense and compliance costs and other professional fees. In
certain cases, enforcement authorities may even cause us to appoint an independent compliance monitor which can result in added costs
and administrative burdens.</p><div>

Accounting Oversight Board (the &#8220;PCAOB&#8221;) and the securities exchanges, impose additional reporting and other obligations on
public companies. Compliance with public company requirements will increase costs and make certain activities more time-consuming. A number
of those requirements have and will require us to carry out activities we have not done previously. For example, we have created new Board
committees and will adopt new internal controls and disclosure controls and procedures. In addition, expenses associated with SEC reporting
requirements will be incurred. Furthermore, if any issues in complying with those requirements are identified, we could incur additional
costs rectifying those issues, and the existence of those issues could adversely affect our reputation or investor perceptions of us.
It may also be more expensive to obtain director and officer liability insurance. Risks associated with our status as a public company
may make it more difficult to attract and retain qualified persons to serve on the Board or as executive officers. The additional reporting
and other obligations imposed by these rules and regulations will increase legal and financial compliance costs and the costs of related
legal, accounting and administrative activities. These increased costs will require us to divert a significant amount of money that could
otherwise be used to expand the business and achieve strategic objectives. Advocacy efforts by stockholders and third parties may also
prompt additional changes in governance and reporting requirements, which could further increase costs.</p><div>

laws. Their limited experience in dealing with the increasingly complex laws pertaining to public companies could be a significant disadvantage
in that it is likely that an increasing amount of their time may be devoted to these activities which will result in less time being devoted
to the management and growth of the combined company. We may not have adequate personnel with the appropriate level of knowledge, experience,

The development and implementation of the standards and controls necessary for the combined company to achieve the level of accounting

the Warrants, it is possible that we may not receive cash upon their exercise since the Warrants may be exercised on a cashless basis.
A cashless exercise allows warrant holders to convert the warrants into shares of our Common Stock without the need for a cash payment.
Instead of paying cash upon exercise, the Warrant holder would receive a reduced number of shares based on a predetermined formula. As
a result, the number of shares issued through a cashless exercise will be lower than if the Warrants were exercised on a cash basis, which
could impact the cash proceeds we receive from the exercise of such warrants.</p><div>

equity-linked and debt financing. In addition, from time to time, we may evaluate acquisitions and other strategic opportunities. If we
elect to pursue any such investments, we may fund them with internally generated funds, bank financing, the issuance of other debt or
equity or a combination thereof. There is no assurance that any such financing or funding would be available to us on acceptable terms
or at all. Sales of securities registered under the registration statement to which this prospectus forms a part could lower the market
price of our Common Stock and warrants. We do not believe this would harm our chances of raising capital, but could affect the sale price

(with any shares unused for such purpose to be retained by such party), and (iii) forfeit the remainder of any Series A Common Stock and
Series B Common Stock held by Sponsor (or 966,441 Series A shares and 1 Series B shares). It was also agreed in the Sponsor Share Letter
that the Sponsor will transfer 200,000 shares to one of ACAB&#8217;s financial advisors for the services provided prior to the merger
date. The transfer of 983,333 shares of ACAB Series A Common Stock to Abpro Bio was reflected in the pro forma condensed financial statements
as a part of the recapitalization in conjunction with the Business Combination and this transfer has no financial impact. As it relates
to 983,333 shares transferred to Abpro, the corresponding issuance costs will be recorded at the date these shares are transferred to
third-party investors against non-redemption or capital commitments. If the 983,333 shares of Series A common stock held by Abpro and
291,667 shares held by the Sponsor are transferred to third-party investors in conjunction with their capital commitments, the maximum
related costs to be recorded to additional paid-in capital will be in the amount of approximately $14.3 million (based on the fair value
of the ACAB&#8217;s common stock shares of $11.20 per share at September 30, 2024) with the corresponding decrease in the paid-in-capital.</p><div>

by the Business Combination Agreement are expected to be used for general corporate purposes. Further, the unaudited pro forma condensed
combined financial information does not purport to project the future operating results or financial position of the Post-Combination
Company following the consummation of the Business Combination. The unaudited pro forma adjustments represent management&#8217;s estimates
based on information available as of the date of these unaudited pro forma condensed combined financial information and are subject to
change as additional information becomes available and analyses are performed. ACAB and Abpro have not had any historical relationship
prior to the transactions discussed in this proxy statement/prospectus. Accordingly, no pro forma adjustments were required to eliminate
activities between the companies.</p><div>

which have been transferred to ACAB&#8217;s directors and Apeiron, and 600,601 Series A common stock shares issued to the Sponsor in extinguishment
of $2,000,000 advances by the Sponsor to ACAB. The one share of Series B common stock held by ACAB&#8217;s sponsor was reduced to zero,
due to the share&#8217;s forfeiture under the terms of the Sponsor Share Letter. The Series A common stock shares held by ACAB&#8217;s
sponsor of 7,200,000 were reduced by 966,441 forfeited shares, 983,333 shares transferred to ABI, 983,333 shares transferred to Abpro,
and 200,000 shares transferred to one of ACAB&#8217;s financial advisors under the terms of the Sponsor Share Letter. As it relates to
983,333 shares transferred to Abpro, the corresponding shares were excluded from the shares outstanding since these shares are held by
New Abpro. The 983,333 shares held by Abpro will be included in the shares outstanding on the date these shares are transferred to third-party
investors against non-redemption or capital commitments. In addition, on April 4, 2023, ACAB and the Sponsor entered into agreements with
several unaffiliated third parties in exchange for them agreeing not to redeem certain public shares of ACAB at the special meeting called
by the Company (the &#8220;Meeting&#8221;) to approve an extension of time for the Company to consummate an initial business combination
(the &#8220;Charter Amendment Proposal&#8221;). In exchange for the foregoing commitments not to redeem such shares, the Sponsor has agreed
to transfer to such investors an aggregate of 825,225 shares of ACAB held by the Sponsor immediately following consummation of an initial
business combination if they continued to hold such Non-Redeemed Shares through the Meeting. As such, at the Closing Date of the Business
Combination, 825,225 shares held by the Sponsor were transferred to the investors. Also, on April&#160;10, 2024, the Sponsor entered into
a subscription agreement with Polar Multi-Strategy Master Fund (&#8220;Polar&#8221;), pursuant to which Polar provided the capital contribution
to the Sponsor in the amount of $360,000&#160;in exchange for&#160;1&#160;share of the Company&#8217;s Series A common stock held by the
Sponsor for each $1&#160;invested by the Investor as of the closing of the Merger. As such, at the Closing Date of the Business Combination,
360,000 shares held by the Sponsor were forfeited and the corresponding number of New Abpro common stock shares were issued to Polar.</p><div>

The actual adjustments may materially differ from the pro forma adjustments that appear in this prospectus. The fair value of the combined Company's position under the Forward Purchase Agreement was calculated using the Monte Carlo simulation, based on the following assumptions: The Company&#8217;s stock price of $11.20 per share as of September 30, 2024, the risk-free rate of 4.73%, the term of three months, and the expected volatility of 100%. The net asset arising from the Forward Purchase Agreement totaled $940,000.

dedicated to developing next-generation antibody therapeutics with the goal of improving the lives of patients with severe and life-threatening
diseases. We are focused on novel antibody constructs for immuno-oncology and ophthalmology. By leveraging our proprietary DiversImmune&#174;
and MultiMabTM antibody discovery and engineering platforms, we are developing a pipeline of antibodies, both independently and through
collaborations with global pharmaceutical and research institutions.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Our two lead product candidates,
ABP-102 and ABP-201, feature our next generation tetravalent antibody format, or TetraBi antibody format, which binds to two different
targets with two distinct binding sites per target. ABP-102 is designed to redirect a patient&#8217;s immune system to fight cancer by
engaging T cells through co-targeting human epidermal growth factor receptor 2, or HER2, and cluster of differentiation 3, or CD3, T-cell
co-receptor. We plan initially to develop ABP-102 for difficult to treat HER2+ solid tumors, focusing on orphan indications. ABP-201 is
designed to block blood vessel formation and normalize damaged vessels through co-targeting vascular endothelial growth factor, or VEGF,
and angiopoietin-2, or ANG-2. We plan to develop ABP-201 to treat vascular disease of the eye, focusing on wet age-related macular degeneration
(Wet AMD). We intend to follow these two lead product candidates with a broad pipeline of CD3-targeting T-cell engagers based on the differentiated
format of ABP-102. We expect to initiate clinical trials for ABP-102 and ABP-201 in 2026.</p><div>

global markets caused by political instability and conflicts, such as the ongoing conflicts in the Ukraine, and Israel, and economic challenges
have led to market disruptions, including significant volatility in commodity prices, credit and capital market instability and supply
chain interruptions, which have caused record inflation globally. Our business, financial condition, and results of operations could be
materially and adversely affected by further negative impacts on the global economy and capital markets resulting from these global economic
conditions, particularly if such conditions are prolonged or worsen. Although, to date, our results of operations have not been materially
impacted by these global economic and geopolitical conditions, it is impossible to predict the extent to which our operations may be impacted
in the short and long term. The extent and duration of these market disruptions, whether as a result of the military conflict between
Russia and Ukraine, the effects of the Russian sanctions, the conflict between Israel and Hamas, geopolitical tensions, record inflation,
or otherwise, are impossible to predict. Any such disruptions may also magnify the impact of other risks described or incorporated by

increased by $0.2 million during the nine months ended September 30, 2024 as compared to the nine months ended September 30, 2023, due
to the revenue earned from the research and development services performed for Celltrion related to ABP-102 development. No such research
and development services revenue was earned during the nine months ended September 30, 2023. Our ability to generate product revenues
in the future will depend almost entirely on our ability to successfully develop, obtain regulatory approval for, and then successfully
commercialize a drug candidate, or enter into collaborations that provide for payments to us.</p><div>

Combination with ACAB, the Company has financed its operations primarily through the sale of equity securities and issuance of promissory
notes and, to a lesser extent, through the revenue from collaboration arrangements. Since its inception, the Company has incurred significant
recurring losses, including a net loss of $3.9 million and $7.9 million for the nine months ended September 30, 2024, and 2023, respectively.
As of September 30, 2024, the Company had an accumulated deficit of $109.5 million. The Company expects to incur operating losses in the
foreseeable future.</p><div>

concern within one year after the original issuance date of our annual financial statements. The Company is planning to raise additional
capital through equity or debt financing to meet its operating cash needs. The Company has based this estimate on assumptions that may
prove to be wrong, and the Company could exhaust its available capital resources sooner than it expects. There can be no assurance that
any required future funding can be successfully completed on a timely basis or terms acceptable to the Company.</p><div>

awards is estimated based on the simplified method for grants to employees and is based on the contractual term for non-employee awards.
The risk- free interest rate assumption is based on observed interest rates appropriate for the terms of the awards. The dividend yield
assumption is based on history and expectation of paying no dividends.</p><div>

our next generation tetravalent antibody format, or TetraBi antibody format, which binds to two different targets with two distinct binding
sites per target.&#160;ABP-102&#160;is designed to redirect a patient&#8217;s immune system to fight cancer by engaging T cells through&#160;co-targeting&#160;human
epidermal growth factor receptor 2, or HER2, and cluster of differentiation 3, or CD3,&#160;T-cell&#160;co-receptor.&#160;We plan initially
to develop&#160;ABP-102&#160;for difficult to treat HER2+ solid tumors, focusing on orphan indications.&#160;ABP-201&#160;is designed
to block blood vessel formation and normalize damaged vessels through&#160;co-targeting&#160;vascular endothelial growth factor, or VEGF,
and&#160;angiopoietin-2,&#160;or&#160;ANG-2.&#160;We plan to develop&#160;ABP-201&#160;to treat vascular disease of the eye, focusing
on wet&#160;age-related&#160;macular degeneration (Wet AMD). We intend to follow these two lead product candidates with a broad pipeline
of&#160;CD3-targeting&#160;T-cell&#160;engagers based on the differentiated format of&#160;ABP-102.&#160;We expect to initiate clinical

format of&#160;ABP-102&#160;provides a potentially transformative approach to immuno-oncology. The TetraBi antibody format features two
affinity-tuned binding sites, and thus bivalent binding for the tumor antigen, creating a stronger connection to the tumor cell compared
to monovalent binding. In addition, the placement of the CD3 binding domain in the middle, or hinge region, of the TetraBi antibody format
results in a therapeutic candidate that, in preclinical studies, selectively activates T cells only in the presence of tumor cells. We
have designed&#160;ABP-102&#160;with the goal of a favorable safety profile and potential for an enhanced therapeutic window.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">ABP-201&#160;is a different
TetraBi antibody format, designed to simultaneously inhibit VEGF and&#160;ANG-2&#160;for the potential treatment of vascular diseases
of the eye, including diabetic macular edema, or DME, and wet&#160;age-related&#160;macular degeneration, or Wet AMD. In both DME and
Wet AMD, blood vessels form abnormally and leak fluid, resulting in vision loss. Whereas VEGF drives new blood vessel formation,&#160;ANG-2&#160;acts
to destabilize blood vessels and contributes to vessel leakage. The current standard of care for DME and Wet AMD includes intravitreal
injections of VEGF-targeted agents, including Eylea (aflibercept), Lucentis (ranibizumab), and Avastin (bevacizumab, used&#160;off-label).&#160;However,
these drugs require eye injections every one to two months and are only effective in a subset of patients, many of whom eventually develop
resistance. Because&#160;ABP-201&#160;has a high binding capacity, with a total of four binding sites per molecule, we believe&#160;ABP-201&#160;could
be administered less frequently than current agents. Recently, the VEGF and&#160;ANG-2&#160;co-targeting&#160;agent Vabysmo (faricimab),
was approved by the FDA, and clinical trial results showed a dose-dependent improvement in best-corrected visual acuity relative to Lucentis,
providing strong support for this approach. In 2022, the combined worldwide sales of Eylea and Lucentis exceeded $10.5&#160;billion according
to company filings. Through our AbMed subsidiary, we have in-licensed certain intellectual property rights relating to ABP-201 from MedImmune
(now AstraZeneca), and are in breach of the terms of our license agreement with MedImmune/AstraZeneca.</p><div>

proteins produced by B cell immune responses to counter threats including infectious entities such as viruses, bacteria, and fungi. Antibodies
can be raised against antigens seen by the immune system as&#160;&#8220;non-self,&#8221;&#160;and therefore antibodies against human proteins
are often raised using a variety of immunization strategies in mice or other animals. The resulting antibodies can then be used as building
blocks to develop therapeutics for molecular targets, including proteins overexpressed on the surface of cancer cells. Because they recognize
their target antigens with high affinity and high specificity, and because they are natural elements of the immune system, antibodies
have been used effectively as drugs for over 30 years. Monoclonal antibodies are the largest and most rapidly growing class of therapeutic
proteins and have become a mainstay of therapeutic options for patients with cancer, autoimmune disorders, and other diseases. As of June&#160;30,
2022, 162 antibody therapies have been approved by at least one regulatory agency in the world, including 122 approvals in the United
States.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">An immunoglobulin G, or IgG,
is the most common type of antibody and comprises two identical heavy chains and two identical light chains, which assemble to form a&#160;Y-shaped&#160;molecule,
as depicted in the following graphic. The bottom tail of the &#8220;Y&#8221; is called the fragment crystallizable, or Fc, region, and
is structurally constant across entire classes of antibodies. The Fc region of an antibody interacts with a variety of receptors on immune
cells and is also responsible for the long circulating half-life of an antibody. The tips of the &#8220;Y&#8221; are called the fragment
variable, or Fv, regions, and contain the antigen-binding sites. A natural antibody recognizes a single target antigen and is therefore
&#8220;monospecific.&#8221; Because it features two identical binding sites, however, it is &#8220;bivalent&#8221; for that target. Bivalency
is a critical feature of natural antibodies. Just as it is much easier to hang from a bar with two arms rather than one, bivalent binding
has been shown in preclinical studies to provide a much stronger connection to the target antigen than would be possible with monovalent
binding.</p><div>

technology platforms: our<i>&#160;DiversImmune<sup>&#174;</sup></i>&#160;platform, which we use to generate therapeutic &#8220;building
blocks,&#8221; which are high affinity and high specificity antibodies with functional activity against therapeutic targets; and our<i>&#160;MultiMab<sup>TM</sup></i>&#160;platform,
which we use to construct therapeutic product candidates by assembling the building blocks into different combinations of&#160;bi-&#160;and
multi-specific antibodies. Together, these platforms support our strategy of building a broad pipeline of next generation antibody therapeutics

was built to address a key bottleneck in the antibody therapeutics industry: the ability to rapidly generate high affinity and high specificity
antibodies against virtually any target of interest. Although<i>&#160;in vitro</i>&#160;methods, such as phage and yeast display, have
been developed to mimic the immune system, these methods typically rely on collections of antibodies from unimmunized donors and as a
result generally yield relatively low affinity antibodies. Improving these antibodies through affinity maturation (<i>i.e.</i>, mutation
and selection) is often a lengthy process and is not always successful. In contrast, the adaptive immune system of a mouse has a&#160;built-in&#160;mechanism
called somatic hypermutation that improves the affinity of antibodies up to one thousand times, yielding high affinity and high specificity
antibodies suitable for therapeutic development.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The greatest challenge with
mouse-based methods, however, lies in generating a strong and diverse immune response to the target of interest. The mammalian immune
system has a mechanism called tolerance that prevents it from making antibodies against proteins that are perceived as &#8220;self.&#8221;
Thus, to generate a strong immune response against a target that is difficult to access, either because the target is not particularly
immunogenic, or capable of producing an immune response, or because the target, a human protein, is very similar to the corresponding
mouse protein, it is necessary to &#8220;break tolerance.&#8221; A key component of our<i>&#160;DiversImmune<sup>&#174;</sup></i>&#160;platform
is our genetically engineered hyperimmune mouse which seeks to solve this problem in two ways. First, the mouse has been genetically engineered
so that more of its antibody-generating B cells survive and proliferate than in a&#160;non-engineered&#160;mouse. This results in a larger
and more diverse collection of high affinity antibodies. Second, the mouse has a hyperactive immune system in which its tolerance to self-antigens
has been &#8220;broken.&#8221; This enables us to generate a diverse array of antibodies against a wide range of targets, including targets
that are very similar between mouse and human.</p><div>

Bivalent binding, or binding with two points of contact, takes advantage of the concept of avidity, specifically that multipoint connections are much stronger than single point connections. In order to maximize efficacy, we build bivalent binding into our therapeutic product candidates where increased strength of binding is desirable. For example,&#160;ABP-102&#160;features two identical binding sites for HER2, rather than one. This enables the molecule to bind tightly to HER2+ tumor cells, forming a strong immunological synapse, or&#160;cell-to-cell&#160;interaction, between the tumor cell and the cytotoxic T cell. We believe this is critical to generating a strong and sustained immune response and differentiates&#160;ABP-102&#160;from other&#160;T-cell&#160;engaging bispecific antibodies that only feature a single binding site for the tumor-specific antigen.</span></td></tr>

To take advantage of these natural functions, we build Fc regions into all our therapeutic product candidates. For example, ABP-102 features a human IgG1 Fc region that promotes a long circulating half-life, and has been further engineered to reduce or eliminate antibody-dependent cell-mediated cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC) to reduce potentially harmful side-effects associated with inflammation and cytokine release.

both product candidates are symmetrical, with two identical heavy chains and two identical light chains. Many bispecific antibody formats

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">One of the most promising
strategies in cancer therapy is to direct cytotoxic T cells to kill tumor cells. This can be achieved using dual-targeting antibodies,
which bind simultaneously to a tumor-specific antigen on a tumor cell and to CD3 on a T cell, bringing these cells into close proximity
and causing the T cell to kill the tumor cell. First-generation bispecific antibodies were called Bispecific&#160;T-cell&#160;Engagers,
or BiTEs, and contained two Fv regions, one for the tumor antigen and one for CD3. Because they do not contain an Fc region, BiTEs have
very short circulating half-lives, requiring patients to wear an infusion pump for continuous intravenous administration. Second-generation
bispecific antibodies contain an Fc region, but typically have only one binding site for the tumor antigen. This results in weaker binding
to the tumor cell than could be achieved with the corresponding bivalent antibody.</p><div>

format improves upon both first-and second-generation bispecific&#160;T-cell&#160;engaging antibodies, as summarized in the following
table. First,&#160;unlike first-generation bispecific antibodies, our TetraBi antibodies contain an Fc region, which provides enhanced
stability and a longer circulating half-life for potentially more convenient dosing. Second, unlike second-generation antibodies, our
TetraBi antibodies have two binding sites for the tumor antigen, rather than one. Bivalent binding promotes maximal efficacy via an avidity-based
binding effect for the tumor associated antigen, allowing for the establishment of strong connections between the T cell and the tumor
cell, leading to sustained activation through clustering of the T cell receptor complex in the presence of high antigen densities. By
placing the&#160;CD3-binding&#160;domain in the hinge region of the molecule, the TetraBi antibody format has been shown in preclinical
studies to exhibit monovalent-like interaction with CD3. This is important in preventing TetraBi antibodies from activating T cells in
the absence of tumor cells, which could lead to undesirable toxicities such as cytokine release syndrome, or CRS, a potentially life-threatening
toxicity associated with T cell targeted therapies. Finally, unlike second-generation antibodies, our TetraBi antibodies contain two identical
heavy chains and two identical light chains. This allows for easy manufacturing, as there is no possibility of mispairing between two
different heavy chains.</p><div>

therapy</b></p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">T cells can also be directed
to kill tumor cells by genetically modifying them to express a chimeric antigen receptor, or CAR. A CAR is a synthetic receptor in which
an Fv domain of an antibody that recognizes a tumor-specific antigen is linked to a portion of the&#160;T-cell&#160;receptor, typically&#160;CD3-zeta,&#160;as
well as one or more costimulatory domains. T cells expressing a CAR, or CAR T cells, bind to and subsequently kill tumor cells expressing
the appropriate antigen. CAR T therapy has demonstrated efficacy in liquid tumors and as of 2023, six CAR T therapeutics have garnered
FDA approval, including agents targeting hematological malignancies such as lymphomas, leukemias, and multiple myeloma. However, there
are currently no approvals in solid tumor indications. Unlike antibody therapy, CAR T therapy is a complex, multi-step process. After
a patient&#8217;s white blood cells are collected, T cells are isolated and activated. They are then genetically engineered to express
the CAR. The CAR T cells then need to be grown for several weeks before being infused back into the patient. Prior to infusion, however,
patients have to undergo chemotherapy to deplete immune cells, providing an opportunity for the CAR T cells to engraft in the patient.
Despite the effectiveness of this approach, there are several challenges to the widespread adoption of CAR T therapy. The process of engineering
CAR T cells is technically challenging, time-consuming, and expensive. In addition, there are significant toxicities associated with CAR
T therapy, including CRS. Although patients receiving CAR T therapy are often treated for CRS while undergoing therapy, treatments for
CRS, namely administration of immuno-suppressive agents, can also reduce the efficacy of the therapy.</p><div>

any advantages of TetraBi antibodies in a clinical trial, and TetraBi antibodies have not yest received marketing approval, we believe
our next-generation&#160;CD3-targeted&#160;T-cell&#160;engagers have several advantages over CAR T therapies. Like CAR T therapy, we are
redirecting cytotoxic T cells to fight cancer. Unlike CAR T therapy, however, potential treatment with our TetraBi antibodies should be
straightforward and convenient for patients. They will not be required to travel large distances to&#160;state-of-the-art&#160;cancer
centers, but may instead be treated by simple intravenous infusion in local clinics. They will not be required to wait weeks for their
T cells to undergo a lengthy and complex modification process, and they will not need to undergo chemotherapy to deplete their immune
cells. It will also be potentially much easier to manage toxicities by altering the dose of the antibody. Finally, our TetraBi antibody
therapy is expected to be less expensive, reducing obstacles associated with payment and reimbursement.</p><div>

a TetraBi antibody targeting HER2 and CD3. It is an affinity-tuned, Fc engineered dual-targeting antibody with a human IgG1-like structure.&#160;ABP-102&#160;features
two binding sites for bivalent binding to cells expressing HER2, and two binding sites for CD3 in a format that promotes functional monovalency
during cell binding. We believe this structure provides greater potential for clinical applications compared with other HER2-directed&#160;T-cell-engaging&#160;bispecific
antibodies that have only one binding site for the tumor-specific antigen (<i>i.e.</i>, HER2), allowing for an avidity-enhanced effect.&#160;ABP-102&#160;is
designed to redirect T cells to tumor cells that are overexpressing HER2 at high or intermediate levels. In preclinical studies, we have
shown that&#160;ABP-102&#160;selectivity promotes T cell activation, cytokine release and cytotoxicity in the presence of HER2-high and
intermediate expressing cells, including HER2+ breast, ovarian, and gastric cancer cell lines. We have also observed reduced or no cytotoxic
activity against cell lines expressing low/endogenous levels of HER2. This feature provides the opportunity for an improved therapeutic
window to attack tumor cells while reducing systemic toxicity by promoting&#160;&#8220;on-target,&#160;on-tumor&#8221;&#160;effects, with
reduced potential for&#160;&#8220;on-target,&#160;off-tumor&#8221;&#160;toxicity toward endogenous tissues. We plan to initiate clinical
trials of&#160;ABP-102&#160;in the first half of 2026 with our partner Celltrion, focusing on HER2+ breast and gastric cancers.</p><div>

common cancer in women in the United States, except for skin cancers. It is about 30% (or 1 in 3) of all new female cancers each year.
The American Cancer Society&#8217;s estimates for breast cancer in the United States for 2023 are: About 297,790 new cases of invasive
breast cancer will be diagnosed in women. About 55,720 new cases of ductal carcinoma in situ (DCIS) will be diagnosed. About 43,700 women
will die from breast cancer. Breast cancer is the second leading cause of cancer death in women (only lung cancer kills more women each
year). The chance that a woman will die from breast cancer is about 1 in 39 (about 2.5%). The American Cancer Society&#8217;s estimates
for stomach cancer (also known as gastric cancer) in the United States for 2023 are approximately 26,500 new cases (15,930 in men and
10,570 in women) and approximately 11,130 deaths (6,690 men and 4,440 women). Stomach cancer accounts for about 1.5% of all new cancers
diagnosed in the United States each year, according to the American Cancer Society.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">ABP-102&#160;is a TetraBi
antibody that is designed to bind simultaneously to HER2 overexpressed on a tumor cell and CD3 on a T cell, thereby bringing the two cells
into close proximity and promoting&#160;T-cell&#160;activation that leads to killing of the tumor cell.&#160;ABP-102&#160;is a differentiated
therapeutic in that it is able to selectively target HER2-high and intermediate expressing cells, with reduced activity on&#160;HER2-low&#160;or
negative cells, an engineered design feature to promote safety for endogenous HER2-expressing tissues. The TetraBi antibody format of&#160;ABP-102&#160;is
intended to improve on the clinical efficacy of HER2 targeted therapy by inducing infiltration of T cells into HER2+ tumors. In addition
to HER2+ breast cancer,&#160;ABP-102&#160;can potentially target any solid tumor in which HER2 is overexpressed, including HER2+ gastric,
esophageal, endometrial, ovarian, colorectal, lung, pancreatic, cervical, gallbladder, and bladder cancers, as well as HER2+ pediatric
indications including osteosarcoma. By targeting both HER2 and CD3,&#160;ABP-102&#160;may overcome many of the limitations of single-targeting
agents. For instance, agents targeting HER2 alone, such as Herceptin, face problems with drug resistance, often caused by alterations
in the HER2 signaling pathway or other related&#160;pro-proliferative&#160;pathways.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">ABP-102&#160;works by a different
mechanism, engaging cytotoxic T cells to kill the tumor cells rather than blocking the function of HER2. As such, we believe that&#160;ABP-102&#160;could
lead to more durable responses in patients, with reduced risk of drug resistance. Furthermore,&#160;ABP-102&#160;possesses an advanced
TetraBi antibody format, unlike that of competing agents that only feature a single binding site for HER2. Having two binding sites for
HER2 enables higher binding potential and selectivity for tumor cells, which may result in greater potency and an improved therapeutic
index. In addition, this dual binding may provide access to a broader patient population, including patients that express intermediate
levels of HER2.</p><div>

both safe and effective, it must only activate T cells when HER2+ tumor cells are present. The key safety risk for&#160;T-cell&#160;engaging
therapies is CRS, in which T cells and other white blood cells become activated, leading to the over-production of&#160;pro-inflammatory&#160;cytokines.
This can cause high fever, swelling, redness, extreme fatigue, nausea, and, in rare cases, death. The&#160;ABP-102&#160;Fc region is engineered
to have reduced binding to Fc receptors and C1q, thereby making T cell engagement the definitive mechanism of action. By positioning the&#160;CD3-binding&#160;domain
near the hinge region of the molecule, it selectively activates T cells only in the presence of HER2+ tumor cells. Thus, when&#160;ABP-102&#160;is
added to T cells or PBMCs alone, the T cells do not release&#160;pro-inflammatory&#160;cytokines like TNFa,&#160;IL-6,&#160;IL-2and&#160;IFNg.
When HER2+ tumor cells are introduced, however,&#160;ABP-102&#160;causes potent activation of the T cells, along with cytokine release
reflecting T cell activation. This strong dependency on HER2 for T cell engagement may result in a beneficial therapeutic index for&#160;ABP-102,&#160;enabling
a dose to be found that is both safe and effective. In addition, HER2 is expressed at lower levels in some tissues of the human body,
including heart and lung tissues. Therefore, we have engineered&#160;ABP-102&#160;to promote selectivity for T cell activation and killing
of HER2-high and intermediate target cells, which is a key differentiating feature.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Through our majority-owned
subsidiary, AbMed Corporation, we are developing&#160;ABP-201&#160;for potential indications in ophthalmology, including DME and Wet AMD.
DME is an eye condition brought on by diabetes in which blood vessels form abnormally and leak fluid into the macula of the eye, resulting
in blurred vision and, in extreme cases, blindness. Wet AMD is similarly a severe eye condition caused by the growth and leakage of abnormal
blood vessels under the retina and macula of the eye, causing the macula to bulge or lift up from its normally flat position, thus distorting
or destroying central vision. VEGF is a clinically validated target in both DME and Wet AMD, where Eylea and Lucentis are approved and
in widespread use. As depicted in the following chart, VEGF and&#160;ANG-2&#160;act in concert to promote angiogenesis. In normal blood
vessel development,&#160;ANG-2&#160;plays a role in destabilizing mature blood vessels, creating an environment in which vessel branching
can occur. VEGF then promotes the sprouting of new blood vessels. In DME and Wet AMD, however, excessive destabilization of blood vessels
by&#160;ANG-2&#160;contributes to vessel leakage, or edema. In addition, upregulation of&#160;ANG-2&#160;is the primary mechanism of resistance
to VEGF inhibition. We believe that effective control of angiogenesis and inhibition of vessel leakage requires simultaneous inhibition
of both pathways.</p><div>

cause of DME and Wet AMD is not completely understood, both VEGF and&#160;ANG-2&#160;play central roles in new blood vessel growth&#8212;a
hallmark common to both ocular diseases. Several biological therapies have been developed to inhibit VEGF by binding to and sequestering
the protein. The current&#160;standard-of-care&#160;includes Lucentis, a recombinant humanized monoclonal antibody fragment that binds
VEGF, and Eylea, a recombinant fusion protein containing portions of the human VEGF receptor. Another VEGF antibody is Avastin, a recombinant
human monoclonal antibody which is approved for the treatment of several cancer indications and is used&#160;off-label&#160;for the treatment
of DME and wet AMD.</p><div>

for the treatment of DME in 2012, the use of intravitreal injections was less common in North America and laser photocoagulation, or the
use of light to coagulate tissue, was the primary treatment. Prior to the Lucentis DME approval, several treatments including Avastin
and Macugen (pegaptanib sodium injection) were used&#160;off-label.&#160;Macugen received&#160;FDA-approval&#160;for the treatment of

and&#160;ANG-2&#160;is to add an&#160;ANG-2&#160;inhibitor to an approved VEGF inhibitor. The shortcoming of this approach is that the
two agents are not physically linked and as a result will accumulate differently and be cleared from the eye at different rates. It is
therefore difficult to ensure that both targets are inhibited in the same place at the same time. In contrast to this dual agent approach,
other investigational agents, including&#160;ABP-201,&#160;use a single-agent dual-targeting antibody to ensure that both targets are
engaged at the same time. Clinical trial results with Vabysmo, a bispecific antibody&#160;co-targeting&#160;VEGF and&#160;ANG-2,&#160;showed
a dose-dependent improvement in best-corrected visual acuity relative to Lucentis, providing strong support for this approach. Importantly,
our single agent approach may have regulatory advantages over the dual agent approach given that the necessary efficacy endpoints for
approval could include&#160;non-inferiority&#160;in contrast with superiority to current&#160;standard-of-care.&#160;The dosing regimens
of current DME and AMD drugs, specifically Lucentis and Eylea, are characterized by relatively frequent injections, initially every month
followed by every other month. The frequency of injection is determined by a combination of the potency of the drug and its clearance
rate from the eye. Large molecules generally clear slower than smaller molecules, and&#160;ABP-201&#160;is approximately twice the size
of Eylea and approximately four times the size of Lucentis.&#160;ABP-201&#160;also has a higher binding capacity than either Eylea or
Lucentis, with two binding sites for VEGF and two binding sites for&#160;ANG-2.&#160;As such, we believe that&#160;ABP-201&#160;will require
less frequent dosing, providing a significant advantage in the commercial setting. In addition, as increased signaling by&#160;ANG-2&#160;in
response to anti-VEGF therapy is one of the primary mechanisms of resistance to VEGF inhibitors, we anticipate that&#160;ABP-201&#160;will
not suffer from drug resistance to the same extent as drugs that target VEGF alone.</p><div>

neovascularization model,&#160;ABP-201&#160;administered intravitreally resulted in comparable reductions in vascular leakage and vascular

The area ablated then heals (becomes revascularized) spontaneously by the formation of neovascular &#8220;lesions.&#8221; Anti-angiogenic
agents can then be assessed by how much they can delay this healing, as measured by how well they can reduce vascular leakage and neovascular
lesion size.</p><div>

in intraocular pressure (IOP) increases comparable to vehicle control (left panel above). Additionally, ocular examinations (OE) to evaluate
ocular surface morphology, anterior segment and posterior segment inflammation, cataract formation, and retinal changes were performed.
The OE scores can range from 0, indicating no abnormalities, to 48, indicating a maximum number of maximally severe abnormalities. Other
than a mild increase in OE score of 5 at day 1 post-injection, which returned to 0 for the duration of the study, the OE scores were identical
to that of the vehicle control. Taken together, the lack of increases in IOP and OE scores suggests that&#160;ABP-201&#160;is well-tolerated.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The vitreous humor in the
human eye is approximately 4 ml. Given the small volume of the vitreous humor, agents injected intravitreally must be able to be sufficiently
concentrated so as to be injected in small enough volumes to not produce significant increases in IOP. Excessive increases in IOP resulting
in ocular hypertension is associated with a variety of adverse events such as ocular inflammation, glaucoma, and retinal detachment. As
such,&#160;ABP-201&#160;formulation efforts have achieved a 100 mg/ml concentration with acceptable biophysical characteristics, especially
viscosity. We believe that this concentration will allow us to administer efficacious dose levels of&#160;ABP-201&#160;in small enough
volumes to avoid toxic increases in IOP. Even so, preliminary evidence suggests that higher concentrations are achievable.</p><div>

designed to bind bivalently to GPC3 on HCC cells and CD3 on cytotoxic T cells, bringing these two cell types into close proximity and
triggering sustained&#160;T-cell&#160;activation and tumor cell killing. GPC3 is an onco-fetal antigen that is only expressed during fetal
development and on HCC cells, making it an ideal tumor antigen target.&#8195;GPC3 expression is also prognostic of poor overall survival
in HCC, suggesting that&#160;ABP-110&#160;may be most effective in the patients at highest risk and most in need of novel therapeutic
interventions. Targeting this patient population may provide for a relatively rapid path to approval given the unmet medical need in HCC.</p><div>

to data published by the Word Health Organization, the COVID pandemic has resulted in over 771&#160;million confirmed cases and over 6&#160;million
deaths have been reported globally. While vaccination efforts have made tremendous strides in bringing the pandemic under control, vaccination
is contraindicated in some individuals, such as the immunocompromised. For these patients, there are no currently available prophylactic
therapies. The only therapies available are Nirmatrelvir/ritonavir, molnupiravir, and remdesivir. While these are effective therapies,
their toxicities preclude them from being used as prophylactics. Monoclonal antibodies are ideal molecules to serve as prophylactic therapies
as they can effectively neutralize the&#160;SARS-CoV-2&#160;virus and have a proven safety profile and can be engineered to extend their
half-lives. However, all antibody therapies and prophylactics to date have become ineffective due to&#160;SARS-CoV-2&#160;viral mutation.
In response to the global pandemic, Abpro sought to develop COVID antibodies targeting highly conserved (resistant to mutation) areas
of the virus with highly potent neutralizing antibodies engineered to have extended half-lives to allow for dosing intervals of greater
than six months, through collaborations with third parties in the form of in-license agreements. Several candidate molecules were evaluated
through different stages of development. The most advanced molecule was developed through GMP manufacturing and evaluated in a clinical
trial. However, the clinical trial was not successful. Since the health threats from the COVID pandemic have now decreased, Abpro is not
planning to focus on this area at this time.</p><div>

Amounts that may be paid by third party collaborators, for example upfronts, milestones and/or royalty payments from territorial commercialization
partners, are also subject to a 50/50 split. Following commercial approval of&#160;ABP-102,&#160;we have agreed to reimburse Celltrion
250% of its direct and certain indirect costs and expenses incurred through first commercial sale. Celltrion is entitled to offset amounts
otherwise due to us under the agreement until our share of these costs has been paid back; provided that we are entitled to a minimum
25% of profit from commercial sales and from third party collaborators regardless of the amount of unreimbursed development costs outstanding
(and then 50% once the reimbursement has been made in full). In addition, we are entitled to up to over $1.75&#160;billion in development

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The term of individual patents
depends upon the legal term for patents in the countries in which they are obtained. In most countries, including the United States, the
patent term is 20&#160;years from the earliest filing date of a&#160;non-provisional&#160;patent application. In the United States, a
patent&#8217;s term may be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the USPTO in
examining and granting a patent, or may be shortened if a patent is terminally disclaimed over an earlier filed&#160;co-owned&#160;patent.
The term of a patent that covers a drug or biological product may also be eligible for patent term extension when FDA approval is granted,
provided statutory and regulatory requirements are met. However, as to the FDA component, the restoration period cannot be longer than
five years and the total patent term including the restoration period must not exceed 14 years following the FDA approval. Additionally,
only one patent may be extended, and only those claims covering the approved drug, a method for using it, or a method for manufacturing
it may be extended. The duration of foreign patents varies in accordance with provisions of applicable local law, but typically is also
20 years from the earliest effective filing date. In the future, if and when our product candidates receive approval by the FDA or foreign
regulatory authorities, we expect to apply for patent term extensions on issued patents covering those products, depending upon the length
of the clinical studies for each product and other factors. There can be no assurance that any of our pending patent applications will
issue or that we will benefit from any patent term extension or favorable adjustments to the terms of any of our patents. The FDA and
the USPTO in the United States, and any equivalent regulatory authority in other countries, may not agree with our assessment of whether
such extensions are available, and may refuse to grant extensions to our patents, or may grant more limited extensions than we request.
An extension may also not be granted because of, for example, a failure to exercise due diligence during the testing phase or regulatory
review process, failing to apply within applicable deadlines, failing to apply prior to the expiration of relevant patents, or otherwise
failing to satisfy applicable requirements. The actual protection afforded by a patent varies on a&#160;product-by-product&#160;basis,
from&#160;country-to-country,&#160;and depends upon many factors, including the type of patent, the scope of its coverage, the availability
of regulatory-related extensions, the availability of legal remedies in a particular country, and the validity and enforceability of the
patent. In addition to patents, we rely upon unpatented trade secrets and&#160;know-how&#160;and continuing technological innovation to
develop and maintain our competitive position. We seek to protect our proprietary information, in part, by executing confidentiality agreements
with our collaborators and scientific advisors, and&#160;non-competition,&#160;non-solicitation,&#160;confidentiality and invention assignment
agreements with our employees and consultants. We also have or intend to implement executed agreements requiring assignment of inventions
with selected scientific advisors and collaborators. These confidentiality agreements are designed to protect our proprietary information
and, in the case of invention assignment agreements, to grant us ownership of technologies that are developed through a relationship with
a third party. However, these agreements may be breached, and we may not have adequate remedies for any breach, with a third party. In
addition, our trade secrets may otherwise become known or be independently discovered by competitors. To the extent that our commercial
partners, collaborators, employees and consultants use intellectual property owned by others in their work for use, disputes may arise
as to the rights in related or resulting&#160;know-how&#160;and inventions.</p><div>

is identified for development, it enters the preclinical or nonclinical testing stage. Nonclinical tests include laboratory evaluations
of product chemistry, toxicity, and formulation, as well as animal studies. An IND sponsor must submit the results of the nonclinical
tests, together with manufacturing information and analytical data, to the FDA as part of the IND. Some nonclinical testing may continue
even after the IND is submitted. In addition to including the results of the nonclinical studies, the IND will also include a protocol
detailing, among other things, the objectives of the clinical trial, the parameters to be used in monitoring safety, and the effectiveness
criteria to be evaluated if the first phase lends itself to an efficacy determination. The IND automatically becomes effective 30 days
after receipt by the FDA, unless the FDA, within the&#160;30-day&#160;time period, places the IND on clinical hold. In such a case, the
IND sponsor and the FDA must resolve any outstanding concerns before clinical trials can begin. A clinical hold may occur at any time
during the life of an IND and may affect one or more specific studies or all studies conducted under the IND.</p><div>

conducted under the supervision of one or more qualified investigators in accordance with GCPs. They must be conducted under protocols
detailing the objectives of the trial, dosing procedures, research subject selection and exclusion criteria, and the safety and effectiveness
criteria to be evaluated. Each protocol, and any subsequent material amendment to the protocol, must be submitted to the FDA as part of
the IND, and progress reports detailing the status of the clinical trials must be submitted to the FDA annually. Sponsors also must report
to the FDA serious and unexpected suspected adverse reactions in a timely manner, any clinically important increase in the rate of a serious
suspected adverse reaction over that listed in the protocol or investigation brochure or any findings from other studies or animal or<i>&#160;in
vitro</i>&#160;testing that suggest a significant risk in humans exposed to the product candidate. An IRB at each institution participating
in the clinical trial must review and approve the protocol before a clinical trial commences at that institution and must also approve
the information regarding the trial and the informed consent form that must be provided to each research subject or the subject&#8217;s
legal representative, monitor the study until completed and otherwise comply with IRB regulations. There are also requirements governing
the reporting of ongoing clinical trials and completed clinical trial results to public registries.</p><div>

study that adequately meets regulatory agency requirements for the evaluation of a product candidate&#8217;s efficacy and safety such
that it can be used to justify the approval of the product. Generally, pivotal studies are also Phase 3 studies but may be Phase 2 studies
if the trial design provides a reliable assessment of clinical benefit, particularly in situations where there is an unmet medical need.
Human clinical trials are inherently uncertain, and Phase 1, Phase 2, and Phase 3 testing may not be successfully completed. The FDA or
the sponsor may suspend a clinical trial at any time for a variety of reasons, including a finding that the research subjects or patients
are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution
if the clinical trial is not being conducted in accordance with the IRB&#8217;s requirements or if the product candidate has been associated
with unexpected serious harm to patients.</p><div>

a new product candidate, sponsors are given opportunities to meet with the FDA at certain points; specifically, prior to the submission
of an IND, at the end of Phase 2 and before a BLA or New Drug Application, or NDA, is submitted. Meetings at other times may be requested.
These meetings can provide an opportunity for the sponsor to share information about the data gathered to date and for the FDA to provide

sponsors usually complete additional animal safety studies, develop additional information about the chemistry and physical characteristics
of the product candidate, and finalize a process for manufacturing commercial quantities of the product candidate in accordance with cGMP
requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and the manufacturer
must develop methods for testing the quality, purity, and potency of the product candidate. To help reduce the risk of the introduction
of adventitious agents with use of biological products, the PHSA emphasizes the importance of manufacturing control for products whose
attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing quality batches of the product
candidate and, among other criteria, the sponsor must develop methods for testing the identity, strength, quality, potency, and purity
of the final biological product. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted

nonclinical studies, and clinical trials, along with descriptions of the manufacturing process, analytical tests and other control mechanisms,
proposed labeling, and other relevant information are submitted to the FDA as part of a BLA requesting approval to market the product.
Under the Prescription Drug User Fee Act, or PDUFA, as amended, each BLA must be accompanied by a significant user fee. The FDA adjusts
the PDUFA user fees on an annual basis. PDUFA also imposes an annual product fee for products and an annual establishment fee on facilities
used to manufacture prescription biological or drug products. Fee waivers or reductions are available in certain circumstances, such as
where a waiver is necessary to protect the public health, where the fee would present a significant barrier to innovation, or where the
applicant is a small business submitting its first human therapeutic application for review.</p><div>

of the application, the FDA reviews a BLA submitted to determine if it is substantially complete before the agency accepts it for filing.
The FDA may refuse to accept for filing any BLA that it deems incomplete or not properly reviewable at the time of submission, and may
request additional information. In this event, the BLA must be resubmitted with the additional information. The resubmitted application
also is subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an&#160;in-depth&#160;substantive
review of the BLA. The FDA reviews the BLA to determine, among other things, whether the proposed product is safe, potent, and/or effective
for its intended use, and has an acceptable purity profile and whether the product is being manufactured in accordance with cGMP. The
FDA may refer applications for novel products or products that present difficult questions of safety or efficacy to an advisory committee,
typically a panel that includes clinicians and other experts, for review, evaluation, and a recommendation as to whether the application
should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such
recommendations carefully when making decisions.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">During the product approval
process, the FDA also will determine whether a Risk Evaluation and Mitigation Strategy, or REMS, plan is necessary to assure the safe
use of the product. If the FDA concludes a REMS plan is needed, the sponsor of the BLA must submit a proposed REMS plan. The FDA will
not approve a BLA without a REMS plan, if required. The FDA has authority to require a REMS plan to ensure that the benefits of a drug
or therapeutic biologic outweigh the risks. Before approving a BLA, the FDA will inspect the facilities at which the product is manufactured.
The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP
requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving
a BLA, the FDA will typically inspect one or more clinical sites to assure that the clinical trials were conducted in compliance with
IND trial requirements and GCP requirements. To assure cGMP and GCP compliance, an applicant must incur significant expenditure of time,
money, and effort in the areas of training, record keeping, production, and quality control. Notwithstanding the submission of relevant
data and information, the FDA may ultimately decide that the BLA does not satisfy its regulatory criteria for approval and deny approval.
Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently than we interpret the same data.
If the agency decides not to approve the BLA in its present form, the FDA will issue a complete response letter that describes all of
the specific deficiencies in the BLA identified by the FDA. The deficiencies identified may be minor, for example, requiring labeling
changes, or major, for example, requiring additional clinical trials. Additionally, the complete response letter may include recommended
actions that the applicant might take to place the application in a condition for approval. If a complete response letter is issued, the
applicant may either resubmit the BLA, addressing all of the deficiencies identified in the letter, or withdraw the application. Even
if a product receives regulatory approval, the approval may be significantly limited to specific indications and dosages or the indications
for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain
contraindications, warnings, or precautions be included in the product labeling. The FDA may impose restrictions and conditions on product
distribution, prescribing, or dispensing in the form of a risk management plan, or otherwise limit the scope of any approval.</p><div>

After the FDA grants Orphan Drug Designation, the generic identity of the drug and its potential orphan use are disclosed publicly by
the FDA. Orphan Drug Designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.
The first BLA applicant to receive FDA approval for a particular active ingredient to treat a particular disease with FDA Orphan Drug
Designation is entitled to a seven-year exclusive marketing period in the United States for that product, for that indication. During
the seven-year exclusivity period, the FDA may not approve any other applications to market the same drug for the same disease, except
in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity. Orphan drug exclusivity
does not prevent the FDA from approving a different drug for the same disease or condition, or the same drug for a different disease or
condition. Among the other benefits of Orphan Drug Designation are tax credits for certain research and a waiver of the BLA application

the necessary approvals by the comparable foreign regulatory authorities before it can commence clinical trials or marketing of the product
in those countries or jurisdictions. The approval process ultimately varies between countries and jurisdictions and can involve additional
product testing and additional administrative review periods. The time required to obtain approval in other countries and jurisdictions
might differ from and be longer than that required to obtain FDA approval. Regulatory approval in one country or jurisdiction does not
ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country or jurisdiction may negatively
impact the regulatory process in others.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">In the United States and markets
in other countries, patients who are prescribed treatments for their conditions and providers performing the prescribed services generally
rely on third-party payors to reimburse all or part of the associated healthcare costs. Significant uncertainty exists as to the coverage
and reimbursement status of products approved by the FDA and other government authorities. Thus, even if a product candidate is approved,
sales of the product will depend, in part, on the extent to which third-party payors, including government health programs in the United
States such as Medicare and Medicaid, commercial health insurers and managed care organizations, provide coverage, and establish adequate
reimbursement levels for, the product. The process for determining whether a payor will provide coverage for a product may be separate
from the process for setting the price or reimbursement rate that the payor will pay for the product once coverage is approved. Third-party
payors are increasingly challenging the prices charged, examining the medical necessity, and reviewing the cost-effectiveness of medical
products and services and imposing controls to manage costs. Third-party payors may limit coverage to specific products on an approved
list, also known as a formulary, which might not include all of the approved products for a particular indication.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">&#160;</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">In order to secure coverage
and reimbursement for any product that might be approved for sale, a company may need to conduct expensive pharmacoeconomic studies in
order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the costs required to obtain FDA or other
comparable marketing approvals. Nonetheless, product candidates may not be considered medically necessary or cost effective. A decision
by a third-party payor not to cover a product candidate could reduce physician utilization once the product is approved and have a material
adverse effect on sales, results of operations and financial condition. Additionally, a payor&#8217;s decision to provide coverage for
a product does not imply that an adequate reimbursement rate will be approved. Further, one payor&#8217;s determination to provide coverage
for a drug product does not assure that other payors will also provide coverage and reimbursement for the product, and the level of coverage
and reimbursement can differ significantly from payor to payor.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">&#160;</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The containment of healthcare
costs also has become a priority of federal, state and foreign governments and other third-party payors, and the prices of drugs have
been a focus in this effort. Governments have shown significant interest in implementing cost-containment programs, including price controls,
restrictions on reimbursement, and requirements for substitution of generic products. Adoption of price controls and cost-containment
measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit a company&#8217;s
revenue generated from the sale of any approved products. Coverage policies and third-party reimbursement rates may change at any time.
Even if favorable coverage and reimbursement status is attained for one or more products for which a company or its collaborators receive
marketing approval, less favorable coverage policies and reimbursement rates may be implemented in the future.</p><div>

ensuring adequate coverage and payment for a product also involves challenges. Pricing of prescription pharmaceuticals is subject to governmental
control in many countries. Pricing negotiations with governmental authorities can extend well beyond the receipt of regulatory marketing
approval for a product and may require a clinical trial that compares the cost effectiveness of a product to other available therapies.
The conduct of such a clinical trial could be expensive and result in delays in commercialization.</p><div>

increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program; extended the Medicaid Drug Rebate
program to utilization of prescriptions of individuals enrolled in Medicaid managed care organizations; subjected manufacturers to new
annual fees and taxes for certain branded prescription drugs; created a new Medicare Part D coverage gap discount program, in which manufacturers
must agree to offer 50% (increased to 70% as of January&#160;1, 2019 and further revised, effective January&#160;1, 2025 under the IRA),&#160;point-of-sale&#160;discounts

Medicaid or the ACA. It is unclear how other healthcare reform measures of the Biden administration or other efforts, if any, to challenge,

2016, President Obama signed the 21st Century Cures Act, or Cures Act, into law. Among other provisions, the Cures Act reauthorized the
existing priority review voucher program for certain drugs intended to treat rare pediatric diseases until 2020; created a new priority
review voucher program for drug applications determined to be material national security threat medical countermeasure applications; revised
the FDCA to streamline review of combination product applications; required the FDA to evaluate the potential use of &#8220;real world
evidence&#8221; to help support approval of new indications for approved drugs; provided a new &#8220;limited population&#8221; approval
pathway for antibiotic and antifungal drugs intended to treat serious or life-threatening infections; and authorized the FDA to designate
a drug as a &#8220;regenerative advanced therapy,&#8221; thereby making it eligible for certain expedited review and approval designations.</p><div>

could have an adverse effect on anticipated revenue from product candidates that we may successfully develop and for which we may obtain
regulatory approval and may affect our overall financial condition and ability to develop products. If we, or any third parties we may
engage, are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or such
third parties are not able to maintain regulatory compliance, our current or any future product candidates we may develop may lose any
regulatory approval that may have been obtained and we may not achieve or sustain profitability.</p><div>

with those rules&#160;and all relevant securities and other laws and regulations regarding the independence of directors. The Nasdaq listing
standards generally define an &#8220;independent director&#8221; as a person, other than an executive officer of a company or any other
individual having a relationship which, in the opinion of the issuer&#8217;s board of directors, would interfere with the exercise of
independent judgment in carrying out the responsibilities of a director.</p><div>

committees of the Board that address risks inherent in their respective areas of oversight. In particular, our Board will be responsible
for monitoring and assessing strategic risk exposure and our audit committee will have the responsibility to consider and discuss the
combined company&#8217;s major financial risk exposures and the steps its management will take to monitor and control such exposures,
including guidelines and policies to govern the process by which risk assessment and management is undertaken. The audit committee will
also monitor compliance with legal and regulatory requirements. Our compensation committee will also assess and monitor whether our compensation
plans, policies and programs comply with applicable legal and regulatory requirements. Our nominating and corporate governance committee
will monitor the effectiveness of our governance guidelines and provide oversight with respect to corporate governance.</p><div>

adopted a Clawback Policy (the &#8220;Clawback Policy&#8221;). Under the policy, in the event New Abpro is required to prepare an accounting
restatement due to material noncompliance of New Abpro with any financial reporting requirement under the U.S. federal securities laws,
the Board will take, in its discretion, such action it deems necessary to recover from its executive officers who received incentive-based
compensation, based on performance in a year for which New Abpro is required to prepare restated financial statements, the excess of what
would have been paid to the executive officer under the accounting restatement. This applies during a lookback period of three years,
and the amounts to be reclaimed are as determined by the Board in its sole discretion. For purposes of the Clawback Policy, an executive
officer is any of New Abpro&#8217;s officers who are required, or who have been required during the immediately preceding three calendar
years, to file reports pursuant to Section 16 of the Exchange Act as well as New Abpro&#8217;s Chief Legal Officer, if not included. This
policy may, in certain circumstances, be applied to other current or former employees whose actions or omissions contributed to the circumstances
requiring the restatement and also involved willful misconduct or a willful violation of any of New Abpro&#8217;s rules. Additionally,
if the Board determines that detrimental conduct has occurred that results in a material adverse impact, any incentive compensation paid
during the prior year may be subject to clawback. Incentive compensation excludes base salary and other compensation but includes equity
compensation and bonuses.</p><div>

Incentive Plan is to enhance New Abpro&#8217;s ability to attract, retain and motivate persons who make (or are expected to make) important
contributions by providing these individuals with equity ownership opportunities and/or equity-linked compensatory opportunities. Equity
awards and equity-linked compensatory opportunities are intended to motivate high levels of performance and align the interests of directors,
employees and consultants with those of stockholders by giving directors, employees and consultants the perspective of an owner with an
equity or equity-linked stake in our company and providing a means of recognizing their contributions to New Abpro&#8217;s success. Our
Board believes that equity ownership opportunities and/or equity-linked compensatory opportunities are necessary to remain competitive
in its industry and are essential to recruiting and retaining the highly qualified employees who help us meet our goals.</p><div>

denominated in shares of New Abpro Common Stock under the New Abpro Incentive Plan immediately prior to, the consummation of the Business
Combination, plus an annual increase on the first day of each fiscal year beginning in 2026 and ending in 2034, equal to the lesser of
(A) five (5%) percent of the shares outstanding on the last day of the immediately preceding fiscal year and (B) such smaller number of
shares as determined by the Board or the Committee (as defined below). Shares subject to an award under the New Abpro Incentive Plan that
are forfeited, cancelled, expired, unexercised or are settled in cash under the New Abpro Incentive Plan will again become available for
awards under the New Abpro Incentive Plan. Shares of Common Stock that are tendered or exchanged by a participant or withheld by New Abpro
as payment in connection with any award under the New Abpro Incentive Plan, as well as any shares exchanged by a participant or withheld
by New Abpro or any subsidiary thereof to satisfy tax withholding obligations related to any full value award, will become available for
subsequent awards under the New Abpro Incentive Plan. Shares, if any, that are tendered or exchanged by a participant or withheld by New
Abpro as full or partial payment in connection with the exercise of any option or SAR under the New Abpro Incentive Plan or the payment
of any tax withholding obligation related thereto or not issued by New Abpro in connection with the stock settlement of any SAR will be
added to the aggregate number of shares available for awards under the New Abpro Incentive Plan. Shares, if any, underlying awards that
are granted in assumption of, or in substitution for, outstanding awards previously granted by an entity acquired by New Abpro or with
which New Abpro combines will not be counted against the aggregate number of shares available for awards under the New Abpro Incentive
Plan.</p><div>

summary under current law of the principal United States federal income tax consequences related to awards under the New Abpro Incentive
Plan. This summary deals with the general federal income tax principles that apply and is provided only for general information. Some
kinds of taxes, such as state, local and foreign income taxes, and federal employment taxes, are not discussed. This summary is not intended

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"><i>Non-Qualified Stock Options</i>.
If an optionee is granted an NSO under the New Abpro Incentive Plan, the optionee should not have taxable income on the grant of the option.
Generally, the optionee should recognize ordinary income at the time of exercise in an amount equal to the fair market value of the shares
acquired on the date of exercise, less the exercise price paid for the shares. The optionee&#8217;s basis in our common stock for purposes
of determining gain or loss on a subsequent sale or disposition of such shares generally will be the fair market value of our common stock
on the date the optionee exercises such option. Any subsequent gain or loss will be taxable as a long-term or short-term capital gain
or loss. We or our subsidiaries or affiliates generally should be entitled to a federal income tax deduction at the time and for the same
amount as the optionee recognizes ordinary income.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"><i>Incentive Stock Options</i>.
A participant receiving ISOs should not recognize taxable income upon grant or at the time of exercise. However, the excess of the fair
market value of the shares of our common stock received over the option exercise price is an item of tax preference income potentially
subject to the alternative minimum tax. If stock acquired upon exercise of an ISO is held for a minimum of two years from the date of
grant and one year from the date of exercise and otherwise satisfies the ISO requirements, the gain or loss (in an amount equal to the
difference between the fair market value on the date of disposition and the exercise price) upon disposition of the stock will be treated
as a long-term capital gain or loss, and we will not be entitled to any deduction. If the holding period requirements are not met, the
ISO will be treated as one that does not meet the requirements of the Code for ISOs and the participant will recognize ordinary income
at the time of the disposition equal to the excess of the amount realized over the exercise price, but not more than the excess of the
fair market value of the shares on the date the ISO is exercised over the exercise price, with any remaining gain or loss being treated
as capital gain or capital loss. We and our subsidiaries or affiliates generally are not entitled to a federal income tax deduction upon
either the exercise of an ISO or upon disposition of the shares acquired pursuant to such exercise, except to the extent that the participant
recognizes ordinary income on disposition of the shares.</p><div>

federal income tax consequences of other awards authorized under the New Abpro Incentive Plan generally follow certain basic patterns:
SARs are taxed and deductible in substantially the same manner as NSOs; nontransferable restricted stock subject to a substantial risk
of forfeiture results in income recognition equal to the excess of the fair market value over the price paid, if any, only at the time
the restrictions lapse (unless the recipient elects to accelerate recognition as of the date of grant through a Section 83(b) election
under the Code); RSUs, dividend equivalents and other stock or cash based awards are generally subject to tax at the time of (unless the
recipient elects to accelerate recognition as of the date of grant through a Section 83(b) election under the Code); RSUs, dividend equivalents

the Board to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote
on specific issuances. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions, future financings
and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third
party from seeking to acquire, a majority of the outstanding voting stock. Additionally, the issuance of preferred stock may adversely
affect the holders of common stock by restricting dividends on the common stock, diluting the voting power of the common stock or subordinating
the liquidation rights of the common stock. As a result of these or other factors, the issuance of preferred stock could have an adverse
impact on the market price of the Common Stock.</p><div>

days after the Closing and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until
the expiration of the Public Warrants in accordance with the provisions of the Warrant Agreement. Notwithstanding the above, if shares
of Common Stock are, at the time of any exercise of a Public Warrant, not listed on a national securities exchange such that they satisfy
the definition of a &#8220;covered security&#8221; under Section&#160;18(b)(1) of the Securities Act, New Abpro may, at its option, require
holders of Public Warrants who exercise their warrants to do so on a &#8220;cashless basis&#8221; in accordance with Section&#160;3(a)(9)
of the Securities Act and, in the event New Abpro so elects, it will not be required to file or maintain in effect a registration statement,
but will use its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption
is not available. In such event, each holder would pay the exercise price by surrendering the Public Warrants for that number of shares
of Common Stock equal to the quotient obtained by dividing (x)&#160;the product of the number of shares of Common Stock underlying the
Public Warrants, multiplied by the excess of the &#8220;fair market value&#8221; (defined below) less the exercise price of the Public
Warrants by (y)&#160;the fair market value. The &#8220;fair market value&#8221; means the volume weighted average price of the shares

above was established to prevent a redemption call unless there is at the time of the call a significant premium to the Public Warrant
exercise price. If the foregoing conditions are satisfied and New Abpro issues a notice of redemption of the Public Warrants, each warrant
holder will be entitled to exercise his, her or its warrant prior to the scheduled redemption date. However, the price of shares of New
Abpro common stock may fall below the $18.00 redemption trigger price (as adjusted for stock splits, stock capitalizations, reorganizations,

Warrants for redemption as described above, its management will have the option to require any holder that wishes to exercise its Public
Warrant to do so on a &#8220;cashless basis.&#8221; In determining whether to require all holders to exercise their warrants on a &#8220;cashless
basis,&#8221; New Abpro&#8217;s management will consider, among other factors, New Abpro&#8217;s cash position, the number of warrants
that are outstanding and the dilutive effect on New Abpro&#8217;s stockholders of issuing the maximum number of shares of P Common Stock
issuable upon the exercise of its Public Warrants. If New Abpro&#8217;s management takes advantage of this option, all holders of Public
Warrants would pay the exercise price by surrendering their warrants for that number of shares of Common Stock equal to the quotient obtained
by dividing (x)&#160;the product of the number of shares of Common Stock underlying the Public Warrants, multiplied by the excess of the
&#8220;fair market value&#8221; of Common Stock over the exercise price of the Public Warrants by (y)&#160;the fair market value. The
&#8220;fair market value&#8221; will mean the average last reported sale price of shares of Common Stock for the ten trading days ending
on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. If New Abpro&#8217;s
management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of
shares of Common Stock to be received upon exercise of the Public Warrants, including the &#8220;fair market value&#8221; in such case.
Requiring a cashless exercise in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a
warrant redemption. If New Abpro calls the Public Warrants for redemption and management does not take advantage of this option, the Sponsor
and its permitted transferees would still be entitled to exercise their Placement Warrants for cash or on a cashless basis using the same
formula described above that other warrant holders would have been required to use had all warrant holders been required to exercise their
warrants on a cashless basis, as described in more detail below.</p><div>

Common Stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of New Abpro
as an entirety or substantially as an entirety in connection with which New Abpro is dissolved, the holders of the warrants will thereafter

their warrants immediately prior to such event. If less than 70% of the consideration receivable by the holders of Common Stock in such
a transaction is payable in the form of Common Stock in the successor entity that is listed for trading on a national securities exchange
or is quoted in an established&#160;over-the-counter&#160;market, or is to be so listed for trading or quoted immediately following such
event, and if the registered holder of the warrant properly exercises the warrant within thirty days following public disclosure of such
transaction, the warrant exercise price will be reduced as specified in the warrant agreement based on the Black-Scholes value (as defined
in the warrant agreement) of the warrant. The purpose of such exercise price reduction is to provide additional value to holders of the
warrants when an extraordinary transaction occurs during the exercise period of the warrants pursuant to which the holders of the warrants
otherwise do not receive the full potential value of the warrants in order to determine and realize the option value component of the
warrant. This formula is to compensate the warrant holder for the loss of the option value portion of the warrant due to the requirement
that the warrant holder exercise the warrant within 30&#160;days of the event. The Black-Scholes model is an accepted pricing model for
estimating fair market value where no quoted market price for an instrument is available.</p><div>

all such Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. To prevent having
to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations,
the Charter and Bylaws will further provide that the federal district courts of the United States of America will be the exclusive forum
for resolving any complaint asserting a cause or causes of action arising under the Securities Act, including all causes of action asserted
against any defendant to such complaint. For the avoidance of doubt, this provision is intended to benefit and may be enforced by New
Abpro, its officers and directors, the underwriters to any offering giving rise to such complaint, and any other professional entity whose
profession gives authority to a statement made by that person or entity and who has prepared or certified any part of the documents underlying
this offering. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless
seek to bring a claim in a venue other than those designated in the exclusive forum provisions. In such instance, New Abpro would expect
to vigorously assert the validity and enforceability of the exclusive forum provisions of the Charter and the Bylaws.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">These exclusive forum provisions
may limit a stockholder&#8217;s ability to bring a claim in a judicial forum that it finds favorable for disputes with New Abpro or its
directors, officers, or other employees and may discourage these types of lawsuits. Furthermore, the enforceability of similar choice
of forum provisions in other companies&#8217; certificates of incorporation or bylaws has been challenged in legal proceedings, and it
is possible that a court could find these types of provisions to be inapplicable or unenforceable. We note that investors cannot waive
compliance with the federal securities laws and the rules and regulations thereunder.</p><div>

not discuss all aspects of U.S. federal income taxation that may be important to particular investors in light of their individual circumstances,
including investors subject to special tax rules (<i>e.g.</i>, financial institutions, insurance companies, broker-dealers, dealers or
traders in securities, tax-exempt organizations, taxpayers that have elected mark-to-market accounting, S corporations, regulated investment
companies, real estate investment trusts, passive foreign investment companies, controlled foreign corporations, U.S. Holders (as defined
below) that will hold Common Stock or Warrants as part of a straddle, hedge, conversion, or other integrated transaction for U.S. federal
income tax purposes, expatriates or former long-term residents of the United States, or investors that have a functional currency other
than the U.S. dollar), all of whom may be subject to tax rules that differ materially from those summarized below. This summary does not
discuss other U.S. federal tax consequences (<i>e.g.</i>, estate or gift tax), any state, local, or non-U.S. tax considerations, or the
Medicare tax or alternative minimum tax. In addition, this summary is limited to investors that will hold our securities as &#8220;capital

gain or loss and will be long-term capital gain or loss if the U.S. Holder&#8217;s holding period for the Common Stock so disposed of
exceeds one year. The amount of gain or loss recognized will generally be equal to the difference between (1) the sum of the amount of

will generally be an amount equal to the sum of the U.S. Holder&#8217;s acquisition cost of the Warrant and the exercise price of such

cashless exercise of a Warrant are not clear under current tax law. A cashless exercise may be nontaxable, either because the exercise

a U.S. Holder&#8217;s initial tax basis in the Common Stock received generally should equal the holder&#8217;s adjusted tax basis in the
Warrant. If the cashless exercise were treated as not being a realization event, it is unclear whether a U.S. Holder&#8217;s holding period
for the Common Stock would commence on the date of exercise of the Warrant or the day following the date of exercise of the Warrant; in
either case, the holding period would not include the period during which the U.S. Holder held the Warrant. If, instead, the cashless

cashless exercise of a Warrant could be treated in part as a taxable exchange in which gain or loss is recognized. In such event, a U.S.
Holder could be deemed to have surrendered a portion of the Warrants being exercised having a value equal to the exercise price of such
Warrants in satisfaction of such exercise price. Although not free from doubt, such U.S. Holder generally should recognize capital gain
or loss in an amount equal to the difference between the fair market value of the Warrants deemed surrendered to satisfy the exercise
price and the U.S. Holder&#8217;s adjusted tax basis in such Warrants. In this case, a U.S. Holder&#8217;s initial tax basis in the Common

is unclear whether a U.S. Holder&#8217;s holding period for the Common Stock would commence on the date of exercise of the Warrant or
the day following the date of exercise of the Warrant; in either case, the holding period would not include the period during which the
U.S. Holder held the Warrant. Due to the uncertainty and absence of authority on the U.S. federal income tax treatment of a cashless exercise,

consult their tax advisors regarding the tax consequences of a cashless exercise.</p><div>

such Non-U.S. Holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification

provide for an adjustment to the number of Common Stock for which the Warrant may be exercised or to the exercise price of the Warrant
in certain events, as discussed in the section of this prospectus captioned &#8220;<i>Description of Securities&#8201;&#8212;&#8201;Warrants</i>.&#8221;
An adjustment which has the effect of preventing dilution generally should not be a taxable event. Nevertheless, a Non-U.S. Holder of
Warrants would be treated as receiving a constructive distribution from us if, for example, the adjustment increases the holder&#8217;s
proportionate interest in our assets or earnings and profits (e.g., through an increase in the number of Common Stock that would be obtained
upon exercise) as a result of a distribution of cash to the holders of our Common Stock which is taxable to such holders as a distribution.
A Non-U.S. Holder would be subject to U.S. federal income tax withholding as described above under &#8220;<i>Non-U.S. Holders&#8201;&#8212;&#8201;Taxation
of Distributions</i>&#8221; under that section in the same manner as if such Non-U.S. Holder received a cash distribution from us on Common

Treasury Regulations and administrative guidance promulgated thereunder commonly referred as the &#8220;Foreign Account Tax Compliance
Act&#8221; (&#8220;FATCA&#8221;) generally impose withholding at a rate of 30% in certain circumstances
on dividends (including constructive dividends) in respect of our securities which are held by or through certain foreign financial institutions
(including investment funds), unless any such institution (1) enters into, and complies with, an agreement with the IRS to report, on
an annual basis, information with respect to interests in, and accounts maintained by, the institution that are owned by certain U.S.
persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments, or (2)
if required under an intergovernmental agreement between the United States and an applicable foreign country, reports such information
to its local tax authority, which will exchange such information with the U.S. authorities. An intergovernmental agreement between the
United States and an applicable foreign country may modify these requirements. Accordingly, the entity through which our securities are
held will affect the determination of whether such withholding is required. Similarly, dividends in respect of our securities held by
an investor that is a non-financial non-U.S. entity that does not qualify under certain exceptions will generally be subject to withholding
at a rate of 30%, unless such entity either (1) certifies to us or the applicable withholding agent that such entity does not have any
&#8220;substantial United States owners&#8221; or (2) provides certain information regarding the entity&#8217;s &#8220;substantial United
States owners,&#8221; which will in turn be provided to the U.S. Department of Treasury. Withholding under FATCA was scheduled to apply
to payments of gross proceeds from the sale or other disposition of property that produces U.S.-source interest or dividends, however,
the IRS released proposed regulations that, if finalized in their proposed form, would eliminate the obligation to withhold on such gross
proceeds. Although these proposed Treasury Regulations are not final, taxpayers generally may rely on them until final Treasury Regulations
are issued. Prospective investors should consult their tax advisors regarding the possible implications of FATCA on their investment in
our securities.</p><div>

in order to avoid information reporting and backup withholding requirements. The certification procedures required to claim a reduced
rate of withholding under a treaty generally will satisfy the certification requirements necessary to avoid the backup withholding as
well. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed
as a credit against such holder&#8217;s U.S. federal income tax liability and may entitle such holder to a refund, provided that the required
information is timely furnished to the IRS.</p><div>

Codification (&#8220;ASC&#8221;) Topic 205-40 &#8220;Presentation of Financial Statements&#8212;Going Concern,&#8221; management has determined
the future viability of the Company is largely dependent on its ability to raise additional capital to finance its operations. The Company
expects to seek additional funding through equity and debt financings, collaboration agreements and research grants. Although the Company
has been successful in raising capital in the past, there is no assurance that it will be successful in obtaining such additional financing
on terms acceptable to the Company, if at all. If the Company is unable to obtain funding, the Company could be forced to delay, reduce
or eliminate its research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect
its business prospects.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Accordingly, based on the considerations discussed above, management
has concluded there is substantial doubt as to the Company&#8217;s ability to continue as a going concern within one year after the date
the condensed consolidated financial statements are issued. If adequate funds are not available, the Company may require initiating steps
to slow cash burn, extending the cash runway until financing can be secured. The unaudited condensed consolidated financial statements
do not include any adjustments with respect to the carrying amounts of assets and liabilities and their classification that might result
from the outcome of this uncertainty.</p>

is imposed on the repurchasing corporation itself, not its shareholders from which shares are repurchased. The amount of the excise tax

However, for purposes of calculating
the excise tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair
market value of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department
of the Treasury (the &#8220;Treasury&#8221;) has been given authority to provide regulations and other guidance to carry out and prevent
the abuse or avoidance of the excise tax.</span></p>

redemption or other repurchase that occurs after December&#160;31, 2022, in connection with a Business Combination, extension vote or
otherwise, may be subject to the excise tax. Whether and to what extent the Company would be subject to the excise tax in connection
with a Business Combination, extension vote or otherwise would depend on a number of factors, including (i)&#160;the fair market value
of the redemptions and repurchases in connection with a Business Combination, extension or otherwise, (ii)&#160;the structure of a Business
Combination, (iii)&#160;the nature and amount of any &#8220;PIPE&#8221; or other equity issuances in connection with a Business Combination
(or otherwise issued not in connection with a Business Combination but issued within the same taxable year of a Business Combination)
and (iv)&#160;the content of regulations and other guidance from the Treasury. In addition, because the excise tax would be payable by
the Company and not by the redeeming holder, the mechanics of any required payment of the excise tax have not been determined. The foregoing
could cause a reduction in the cash available on hand to complete a Business Combination and impact the Company&#8217;s ability to complete
a Business Combination.</span></p>

such extended transition period which means that when a standard is issued or revised and it has different application dates for public

ASC 740 identifies usage of an effective annual tax rate for purposes of an interim provision, it does allow for estimating individual
elements in the current period if they are significant, unusual or infrequent. Computing the effective tax rate for the Company is complicated
due to the potential impact of the timing of any Business Combination expenses and the actual interest income that will be recognized
during the year. The Company has taken a position as to the calculation of income tax expense in a current period based on ASC 740-270-25-3
which states, &#8220;If an entity is unable to estimate a part of its ordinary income (or loss) or the related tax (benefit) but is otherwise
able to make a reasonable estimate, the tax (or benefit) applicable to the item that cannot be estimated shall be reported in the interim
period in which the item is reported.&#8221; The Company believes its calculation to be a reliable estimate and allows it to properly
take into account the usual elements that can impact its annualized book income and its impact on the effective tax rate. As such, the
Company is computing its taxable income (loss) and associated income tax provision based on actual results through September 30, 2024.</span></p></ix:continuation>

740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise&#8217;s financial statements and prescribes
a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected

by taxing authorities. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim

the derivative instrument is initially recorded at fair value on the grant date and re-valued at each reporting date, with changes in
the fair value reported in the statements of operations. The classification of derivative instruments, including whether such instruments
should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative assets and liabilities are
classified in the balance sheet as current or non-current based on whether or not net-cash settlement or conversion of the instruments
could be required within 12 months of the balance sheet date. The Company accounted for the warrants issued in connection with the Initial
Public Offering and the private placement as equity under the guidance at FASB ASC Topic 815.</p></ix:continuation>

&#8220;Compensation<b><i>&#8212;</i></b>Stock Compensation,&#8221; guidance to account for its share-based compensation. It defines a
fair value-based method of accounting for an employee share option or similar equity instrument. The Company recognizes all forms of share-based
payments, including share option grants, warrants and restricted share grants, at their fair value on the grant date, which are based
on the estimated number of awards that are ultimately expected to vest. Share-based payments, excluding restricted shares, are valued
using a Black-Scholes option pricing model. Grants of share-based payment awards issued to nonemployees for services rendered have been
recorded at the fair value of the share-based payment, which is the more readily determinable value. The grants are amortized on a straight-line
basis over the requisite service periods, which is generally the vesting period. If an award is granted, but vesting does not occur, any
previously recognized compensation cost is reversed in the period related to the termination of service. Share-based compensation expenses
are included in costs and operating expenses depending on the nature of the services provided in the statements of operations.</p></ix:continuation>

to deposits into the trust account maintained for the benefit of the Company&#8217;s public stockholders of the lesser of (a) $30,000

vote, elect to extend the business combination deadline on a monthly basis by an additional six months through September&#160;19, 2024.
The Company entered into a business combination agreement with a business combination target on December&#160;11, 2023 however, the completion
of this transaction is subject to the conditions noted above. These matters raise substantial doubt about the Company&#8217;s ability
to continue as a going concern. Management&#8217;s plans with regard to these matters are also described in Note 1. The financial statements
do not include any adjustments that may be necessary should the Company be unable to continue as a going concern.</p><div>

If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could
include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead
expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at

all forms of share-based payments, including share option grants, warrants and restricted share grants, at their fair value on the
grant date, which are based on the estimated number of awards that are ultimately expected to vest. Share-based payments, excluding
restricted shares, are valued using a Black-Scholes option pricing model. Grants of share-based payment awards issued to
nonemployees for services rendered have been recorded at the fair value of the share-based payment, which is the more readily
determinable value. The grants are amortized on a straight-line basis over the requisite service periods, which is generally the
vesting period. If an award is granted, but vesting does not occur, any previously recognized compensation cost is reversed in the
period related to the termination of service. Share-based compensation expenses are included in costs and operating expenses
depending on the nature of the services provided in the statements of operations.</p></ix:continuation>

the two-class method to compute basic and diluted net loss per share attributable to common stockholders when shares meet the definition
of participating securities. Series A, Series B, Series C, Series D, Series E and Series F (see Note 9) meet the definition of participating
securities. The two-class method determines net income loss per common share for each class of common and participating securities according
to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income available
to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to
share in the earnings as if all income for the period had been distributed. During periods of loss, there is no allocation required under
the two-class method due to there being no distributed earnings for the period coupled with the fact that the Company&#8217;s Series A,
Series B, Series C, Series D, Series E and Series F do not contain a contractual right to absorb losses. Thus, all undistributed losses

share attributable to common stockholders is computed by dividing net loss attributable to common stockholders by the weighted-average
number of common shares outstanding during the period without consideration of potentially dilutive common stock. Diluted net loss per
share attributable to common stockholders reflects the potential dilution that could occur if securities or other contracts to issue common
stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the
Company unless inclusion of such shares would be anti-dilutive. As the Company has incurred losses for the nine months ended September
30, 2024 and 2023, basic and diluted net loss per share is the same for each period.</p><div>

a reportable segment&#8217;s expenses. This ASU requires that a public entity that has a single reportable segment provide all the disclosures
required by the amendments in this ASU and all existing segment disclosures in Topic 280. Additionally, this ASU requires disclosures
of significant segment expenses provided to the Chief Operating Decision Maker (&#8220;CODM&#8221;) and included in reported measures of
segment profit and loss. Disclosure of the title and position of the CODM is required. This ASU requires interim and annual disclosures
about a reportable segment&#8217;s profit or loss and assets. Furthermore, this ASU requires disclosure of other segment items by reportable
segment including a description of its composition. This ASU is effective for fiscal years beginning after December 15, 2023, and interim
periods within fiscal years beginning after December 15, 2024, on a retrospective basis. The disclosures will be implemented as required
for the year-ended December 31, 2024. The Company is currently evaluating the impact of adopting this standard on its financial statements.</p><div>

Corporation and Subsidiary (the &#8220;Company&#8221;) as of December&#160;31, 2023 and 2022, the related consolidated statements of operations,
convertible preferred stock and stockholders&#8217; deficit and cash flows for the years then ended, and the related notes to the consolidated
financial statements (collectively, the &#8220;financial statements&#8221;). In our opinion, the financial statements present fairly,

its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.</p><div>

the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company has incurred net losses
since its inception, and has negative cash flows from operations and will need additional funding to complete planned development efforts.
This raises substantial doubt about the Company&#8217;s ability to continue as a going concern. Management&#8217;s plans in regard to
these matters also are described in Note 1. The financial statements do not include any adjustments that might result from the outcome
of this uncertainty.</p><div>

of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control

included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation

will be converted into the right to receive the number of shares of newly issued ACAB Series A Common Stock (the &#8220;ACAB New Common

events, considered in the aggregate, that raise substantial doubt abouts its ability to continue as a going concern within one year after
the date that the consolidated financial statements are available to be issued. Through December&#160;31, 2023, the Company has funded
its operations mainly through equity and debt financing and to a lesser extent, payments received in connection with collaboration and
license agreements.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.25in; text-align: justify">Since inception, the Company has incurred recurring losses, including
a net loss of $11,706 and $17,215 for the years ended December&#160;31, 2023 and 2022, respectively. The Company had an accumulated deficit
of $105,571 as of December&#160;31, 2023. The Company expects to incur operating losses for the foreseeable future. On October&#160;18,
2023, the Company entered into a promissory note agreement with Abpro Bio International, Inc. (&#8220;ABI&#8221;), a significant investor
in the Company&#8217;s Series E and F convertible preferred stock (See Note 9), to receive up to $6,000. The Company received $3,315 through
the date of issuance of these consolidated financial statements under this promissory note, including $1,442 during the year ended December&#160;31,

to raise additional capital to finance its operations. The Company expects to seek additional funding through equity and debt financings,
collaboration agreements and research grants. Although the Company has been successful in raising capital in the past, there is no assurance
that it will be successful in obtaining such additional financing on terms acceptable to the Company, if at all. If the Company is unable
to obtain funding, the Company could be forced to delay, reduce or eliminate its research and development programs, product portfolio
expansion or commercialization efforts, which could adversely affect its business prospects.</p><div>

has concluded there is substantial doubt as to the Company&#8217;s ability to continue as a going concern within one year after the date
the consolidated financial statements are issued. The Company plans to continue to fundraise, as well as seek alternate revenues from
collaboration and license agreements. If adequate funds are not available, the Company may require initiating steps to slow cash burn,
extending the cash runway until financing can be secured. The consolidated financial statements do not include any adjustments with respect
to the carrying amounts of assets and liabilities and their classification that might result from the outcome of this uncertainty.</p><div>

conformity with U.S. GAAP requires management to make estimates and judgments that affect the amounts reported in the consolidated

these consolidated financial statements include stock-based compensation expense, fair value of common stock, revenue allocated to
various performance obligations under license and collaboration agreements, pre-clinical and clinical accrued expenses, discount
rates in relation to lease right-of-use assets and liabilities, valuation and realizability of deferred tax assets and the ability
to continue as a going concern. On an ongoing basis, the Company evaluates its estimates, judgments, and methodologies. The Company
bases its estimates on historical experience and on various other assumptions believed to be reasonable. Due to the inherent
uncertainty involved in making estimates, actual results could differ materially from those estimates.</p><div>

employees at the location at the time due to COVID. Accordingly, the Company recorded the estimated amount in accounts payable, and subsequently
engaged in discussion with Mabwell about the invoiced amount and its validity. The Company continues to dispute the amount and its contractual

that the entity expects to receive in exchange for those goods or services.&#160;To determine revenue recognition for arrangements
the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i)&#160;identify the
contract(s) with a customer; (ii)&#160;identify the performance obligations in the contract; (iii)&#160;determine the transaction
price; (iv)&#160;allocate the transaction price to the performance obligations in the contract; and (v)&#160;recognize revenue when
(or as) the Company satisfies a performance obligation.&#160;The Company only applies the five-step model to contracts when it is
probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the
customer.&#160;At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the
goods or services promised within each contract and determines those that are performance obligations, and assesses whether each
promised good or service is distinct.&#160;The Company then recognizes as revenue the amount of the transaction price that is
allocated to the respective performance obligation when (or as) the performance obligation is satisfied.</p><div>

the Company&#8217;s proposed products, an evaluation or benchmark of the Company&#8217;s competition, the current business climate in

common stock, and as such, volatility is estimated using historical volatilities of similar public entities. The peer group was

amount of historical information regarding the volatility of its own stock price becomes available. The expected term of the awards
is estimated based on the simplified method for grants to employees and is based on the contractual term for non-employee awards.
The risk-free interest rate assumption is based on observed interest rates appropriate for the terms of the awards. The dividend
yield assumption is based on history and expectation of paying no dividends.</p><div>

compute basic and diluted net loss per share attributable to common stockholders when shares meet the definition of participating
securities. The two-class method determines net loss per common share for each class of common and participating securities
according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires
income available to common stockholders for the period to be allocated between common and participating securities based upon their
respective rights to share in the earnings as if all income for the period had been distributed. During periods of loss, there is no
allocation required under the two-class method due to there being no distributed earnings for the period coupled with the fact that
the Company&#8217;s Series A, Series B, Series C, Series D, Series E and Series F (see Note 10) do not contain a contractual right
to absorb losses. Thus, all undistributed losses were allocated entirely to the Company&#8217;s outstanding common stock.</p><div>

by dividing net loss attributable to common stockholders by the weighted-average number of common stock outstanding during the period

potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock
or resulted in the issuance of common stock that then shared in the earnings of the Company unless inclusion of such shares would be anti-dilutive.
As the Company has incurred losses for the years ended December&#160;31, 2023 and 2022, basic and diluted net loss per share is the same
for each period.</p><div>

pursuant to a settlement agreement entered into with this vendor on January&#160;23, 2023. Under the settlement agreement, the Company
agreed to pay a total of $1,644 to the vendor, with $600 due 5 business days after the settlement effective date and ten monthly installments,
approximately $104 of each, starting in February 2023. This settlement amount was included in the accounts payable in the consolidated

Company&#8217;s 2014 Stock Incentive Plan (the &#8220;2014 Plan&#8221;) provides for the Company to sell or issue restricted common stock,
or to grant incentive stock options or nonqualified stock options for the purchase of common stock, to employees, members of the Board
and consultants of the Company. The 2014 Plan is administered by the Board, or at the discretion of the Board, by a committee of the
Board. Stock options granted to employees and directors typically vest over four years. Stock options granted to non-employees typically
vest immediately at the grant date. The maximum contractual term of the stock options is ten years. In March 2022, the 2014 Plan was
amended to reserve an additional 1,000,000 shares of common stock. As amended, a total of 6,534,395 shares of common stock may be issued
under the 2014 Plan. As of December&#160;31, 2023, there were 695,921 shares available for future grants.</span></p><div>

Company regularly assesses the need for a valuation allowance against its deferred tax assets. In making that assessment, the Company
considers both positive and negative evidence related to the likelihood of realization of the deferred tax assets to determine, based
on the weight of available evidence, whether it is more-likely-than-not that some or all of the deferred tax assets will not be realized.
In assessing the realizability of deferred tax assets, the Company considers taxable income in prior carryback years, as permitted under
the tax law, forecasted taxable earnings, tax planning strategies, and the expected timing of the reversal of temporary differences.
This determination requires significant judgment, including assumptions about future taxable income that are based on historical and
projected information and is performed on a jurisdiction-by-jurisdiction basis.</span></p><div>

Company continues to maintain a valuation allowance against its deferred tax assets. During the years ended December&#160;31, 2023 and
2022, management assessed the positive and negative evidence in its operations, and concluded that it is more likely than not that its
deferred tax assets as of December&#160;31, 2023 and 2022 will not be realized given the Company&#8217;s history of operating losses.
The valuation allowance against deferred tax assets increased by approximately $3,540 and $4,965 during 2023 and 2022, respectively.</span></p><div>

December&#160;22, 2017, the Tax Cuts and Jobs Act (the &#8220;Act&#8221;) was enacted. Under the Act, research and development expenditures
incurred for tax years beginning after December&#160;31, 2021 must be capitalized and amortized ratably over five or fifteen years for
tax purposes, depending on if the research activities are conducted in the U.S. or outside the U.S., respectively. Effective January&#160;1,
2022, the Company has complied with the mandatory capitalization and amortization of research and experimentation expenditures. For the
year ended December&#160;31, 2023, the Company capitalized $4,416 and received $1,850 of amortization deductions related to such Section&#160;174
expenditures, which on a tax effected basis represent $3,183 of the deferred tax assets shown in capitalized research expenses in the
components of deferred tax assets and liabilities table above. For the year ended December&#160;31, 2022, the Company capitalized $9,790

calculation of the Company&#8217;s tax liabilities involves dealing with uncertainties in the application of complex tax regulations
in a multitude of jurisdictions. The Company recognizes liabilities for uncertain tax positions based on a two-step process. First, management
determines whether it is more likely than not that the tax positions will be sustained on audit, including resolution of related appeals
or litigation processes, based on their technical merits. Second, management measures the tax benefit of those positions as the largest
amount that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. While the Company believes
that it has appropriate support for the positions taken on its tax returns, the Company regularly assesses the potential outcome of examinations
by tax authorities in determining the adequacy of its provision for income taxes. As of December&#160;31, 2023 and 2022, the Company
did not have any uncertain tax positions.</span></p><div>

by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.</p><div>

designees in connection with Closing, (y) 825,225 shares of which were transferred to ACAB's designees in connection with Closing,
and (z) 2,881,667 shares retained by the Sponsor, (B) 50,000 shares of Common Stock issued to Apeiron Investment Group Ltd. at a value
of $7.25 per share, and (C) 250,000 shares of Common Stock transferred from the Sponsor to former directors of ACAB for no additional
consideration on October 25, 2021, (xii) an aggregate of 9,498,900 shares of Common Stock issued as Merger Consideration (defined below)
to officers and directors of the Company at a value of $10.00 per share, (xiii) up to 10,102,000 shares of Common Stock issuable pursuant
to the Standby Equity Purchase Agreement (the "
SEPA
") with YA II PN, Ltd. ("
Yorkville
"), which represents
the number of shares of Common Stock representing the Exchange Cap (as defined in the SEPA), including 297,160 shares of Common Stock
issued to Yorkville as commitment shares pursuant to the terms of the SEPA (the "
Commitment Shares
"); and (b) the
selling warrant holders named in this prospectus (including their permitted transferees, donees, pledgees and other successors-in-interest)
(collectively, the "
Selling Warrantholders
" and, together with the Selling Shareholders and including their permitted
transferees, the "
Selling Securityholders
") of up to an aggregate of 13,850,000 Placement Warrants.
As of the Effective Date,
as defined in the SEPA, there were 50,535,272 shares of Common Stock outstanding, and therefore the Exchange Cap would be 10,102,000
shares of Common Stock. Thus we are registering the maximum amount that we could register without obtaining approval of stockholders
in accordance with Nasdaq's "minimum price rule." However, if the Company desires to issue more than 10,102,000 shares
of Common Stock at an average price per share that does not equal or exceed $4.31 (which represents the lower of (i) the Nasdaq Official
Closing Price (as reflected on Nasdaq.com) immediately preceding the Effective Date; or (ii) the average Nasdaq Official Closing Price
for the five trading days immediately preceding the Effective Date), it would be required to obtain stockholder approval under the Nasdaq
listing rules.
On November 13, 2024, ACAB
completed a series of transactions that resulted in the combination (the "
Business Combination
") of ACAB with Abpro
Corporation pursuant to the previously announced Business Combination Agreement, dated December 11, 2023, amended by an amendment dated
September 4, 2024 (the "
BCA
"), by and among ACAB, Abpro Merger Sub Corp., a Delaware corporation and a wholly owned
subsidiary of ACAB ("
Merger Sub
"), and Abpro Corporation (the "
Closing
"), following the approval
at the special meeting of the shareholders of ACAB held on November 7, 2024 (the "
Special Meeting
"). On November 12,
2024, pursuant to the BCA, and as described in greater detail in the Company's final prospectus and definitive proxy statement,
which was filed with the U.S. Securities and Exchange Commission (the "
SEC
") on October 18, 2024 (the "
Proxy
Statement/Prospectus
"), Merger Sub merged with and into Abpro Corporation, with Abpro Corporation surviving the merger as a
wholly owned subsidiary of ACAB, and ACAB changed its name to Abpro Holdings, Inc. As consideration for the Business Combination, New
Abpro issued to or reserved for Abpro Corporation shareholders an aggregate of approximately 50,000,000 shares of Common Stock, consisting
of 39,123,200 shares of Common Stock issued to Abpro Corporation shareholders, and 10,872,400 shares of Common Stock reserved for issuance
in connection with certain Abpro Corporation rollover RSUs and stock options (collectively, the "
Merger Consideration
").
In addition, New Abpro issued an aggregate of 3,367,401 shares of Common Stock to the PIPE investors in connection with the PIPE Offering,
an aggregate of 1,282,852 Vendor Shares to various vendors in connection with the Closing, and Sponsor forfeited and New Abpro cancelled
966,442 shares of Common Stock.
Simultaneous with the Closing,
New Abpro also completed its previously announced private investment in public equity, issuing 1,122,467 shares of Common Stock and 2,244,934
Incentive Shares in the PIPE Offering, which raised $7.0 million in gross proceeds.
As described herein, the Selling
Securityholders named in this prospectus or their permitted transferees, may resell from time to time up to 31,785,312 shares of Common
Stock and 13,850,000 Placement Warrants. We are registering the offer and sale of these securities to satisfy certain registration rights
we have granted. The Selling Securityholders may offer, sell or distribute all or a portion of the securities hereby registered publicly
or through private transactions at prevailing market prices or at negotiated prices. We will not receive any of the proceeds from such
sales of our Common Stock or Placement Warrants, except with respect to amounts received by us upon the exercise of the Placement Warrants.
We will bear all costs, expenses and fees in connection with the registration of these securities, including with regard to compliance
with state securities or "blue sky" laws. The Selling Securityholders will bear all commissions and discounts, if any, attributable
to their sale of Common Stock or Warrants. See section entitled "
Plan of Distribution
" beginning on page 150 of
this prospectus.
We believe the likelihood
that the warrant holders will exercise their Warrants, and therefore the amount of cash proceeds that we would receive is, among other
things, dependent upon the market price of our Common Stock. If the market price for our Common Stock is less than the exercise price
of $11.50, subject to adjustment as described herein, we believe such holders will be unlikely to exercise their Warrants, as applicable,
For additional information, see "
Risks Related to an Investment in Our Securities
."
The Common Stock being registered for resale in this prospectus represent
a substantial percentage of our public float and of our outstanding Common Stock. The number of shares being registered in this prospectus
(which include shares issuable upon exercise of the Warrants and shares issuable pursuant to the SEPA) represents approximately 117.0%
of the total Common Stock outstanding as of December 23, 2024, which was 51,815,765 shares of Common Stock. In addition, the securities
beneficially owned by the Sponsor represent approximately 6.7% of the total Common Stock outstanding, and this holder will have the ability
to sell all of its shares pursuant to the registration statement of which this prospectus forms a part so long as it is available for
use and the six month lockup period has expired. The sale of the securities being registered in this prospectus, or the perception in
the market that such sales may occur, could result in a significant decline in the public trading price of our Common Stock.
In addition, some of the shares being registered for resale were acquired
by the Selling Securityholders for nominal consideration or purchased for prices considerably below the Business Combination price and
the current market price of the Common Stock. Even though the current market price is significantly below the price at the time of the
ACAB IPO, certain Selling Securityholders have an incentive to sell because they will still profit on sales due to the lower price at
which they acquired their shares as compared to the public investors. In particular, the Sponsor may experience a positive rate of return
on the securities it purchased due to the differences in the purchase prices described above, to the extent they acquired such securities
for less than the relevant trading price, and the public securityholders may not experience a similar rate of return on the securities
they purchased due to the differences in the purchase prices described above. Based on the last reported sale price of Common Stock referenced
below, shares acquired for less than such last reported sale price, the Selling Securityholders may experience potential profit up to
$1.49 per share.
Our Common Stock and our Public
Warrants are listed on the Nasdaq Global Market under the symbols "ABP" and "ABPWW," respectively. On December
20, 2024, the closing price of our Common Stock was $2.07 and the closing price for our Public Warrants was $0.10.
We are an "emerging
growth company" as defined under the federal securities laws and, as such, have elected to comply with certain reduced public company
reporting requirements.
Investing in our Common
Stock and Warrants is highly speculative and involves a high degree of risk. See the section entitled
"Risk Factors
"
beginning on page 7 of this prospectus.
Neither the Securities
and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the accuracy
or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

ABOUT THIS PROSPECTUS
This prospectus is part of
a registration statement that we filed with the SEC using a "shelf" registration process. By using a shelf registration statement,
the Selling Securityholders may sell up to 31,785,312 shares of Common Stock and up to 13,850,000 Warrants from time to time in one or
more offerings as described in this prospectus. We will not receive any proceeds from the sale of Common Stock or Warrants by the Selling
Securityholders. This prospectus also relates to the issuance by up to 28,850,000 shares of Common Stock upon the exercise of Warrants.
We will receive the proceeds from any exercise of the Warrants for cash.
We may also file a prospectus

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This prospectus contains
forward-looking statements, including statements about the anticipated benefits of the Business Combination, and the financial conditions,
results of operations, earnings outlook and prospects of New Abpro and other statements about the period following the consummation of
the Business Combination. Forward-looking statements appear in a number of places in this prospectus including, without limitation, in
the sections titled "
New Abpro's Management's Discussion and Analysis of Financial Condition and Results of Operations
"
and "
Business of New Abpro
." In addition, any statements that refer to projections, forecasts or other characterizations
of future events or circumstances, including any underlying assumptions, are forward-looking statements. Forward-looking statements are
typically identified by words such as "plan," "believe," "expect," "anticipate," "intend,"
"outlook," "estimate," "forecast," "project," "continue," "could,"
"may," "might," "possible," "potential," "predict," "should,"
"would" and other similar words and expressions, but the absence of these words does not mean that a statement is not forward-looking.
The forward-looking statements
are based on the current expectations of the management of New Abpro and are inherently subject to uncertainties and changes in circumstances
and their potential effects and speak only as of the date of such statement. There can be no assurance that future developments will
be those that have been anticipated.
All subsequent written and
oral forward-looking statements concerning the Business Combination or other matters addressed in this prospectus and attributable to
New Abpro or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred
to in this prospectus. Except to the extent required by applicable law or regulation, New Abpro undertakes no obligation to update these
forward-looking statements to reflect events or circumstances after the date of this prospectus or to reflect the occurrence of unanticipated
events.
v
PROSPECTUS SUMMARY
This summary highlights
certain information appearing elsewhere in this prospectus. Because it is only a summary, it does not contain all of the information
that you should consider before investing in our Securities and it is qualified in its entirety by, and should be read in conjunction
with, the more detailed information appearing elsewhere in this prospectus. Before you decide to invest in our Securities, you should
read the entire prospectus carefully, including "Risk Factors" and the financial statements of New Abpro and related notes
thereto included elsewhere in this prospectus.
The Company
New Abpro is a biotechnology
company dedicated to developing next-generation antibody therapeutics with the goal of improving the lives of patients with severe and
life-threatening diseases. New Abpro is focused on novel antibody constructs for immuno-oncology and ophthalmology. By leveraging its
proprietary DiversImmune® and MultiMab
TM
antibody discovery and engineering platforms, New Abpro is developing a pipeline
of next-generation antibodies, both independently and through collaborations with global pharmaceutical and research institutions.
The Background
On November 13, 2024, ACAB
completed a series of transactions that resulted in the combination (the "
Business Combination
") of ACAB with Abpro
Corporation pursuant to the previously announced Business Combination Agreement, dated December 11, 2023, amended by an amendment dated
September 4, 2024 (the "
BCA
"), by and among ACAB, Abpro Merger Sub Corp., a Delaware corporation and a wholly owned
subsidiary of ACAB ("
Merger Sub
"), and Abpro Corporation (the "
Closing
"), following the approval
at the special meeting of the shareholders of ACAB held on November 7, 2024 (the "
Special Meeting
"). On November 12,
2024, pursuant to the BCA, and as described in greater detail in the Company's final prospectus and definitive proxy statement,
which was filed with the U.S. Securities and Exchange Commission (the "
SEC
") on October 18, 2024 (the "
Proxy
Statement/Prospectus
"), Merger Sub merged with and into Abpro Corporation, with Abpro Corporation surviving the merger as a
wholly owned subsidiary of ACAB, and ACAB changed its name to Abpro Holdings, Inc. As consideration for the Business Combination, New
Abpro issued to or reserved for Abpro Corporation shareholders an aggregate of approximately 50,000,000 shares of Common Stock, consisting
of 39,123,200 shares of Common Stock issued to Abpro Corporation shareholders, and 10,872,400 shares of Common Stock reserved for issuance
in connection with certain Abpro Corporation rollover RSUs and stock options (collectively, the "
Merger Consideration
").
In addition, New Abpro issued an aggregate of 3,367,401 shares of Common Stock to the PIPE investors in connection with the PIPE Offering,
an aggregate of 1,282,852 Vendor Shares to various vendors in connection with the Closing, and Sponsor forfeited and New Abpro cancelled
966,442 shares of Common Stock.
Simultaneous with the Closing,
New Abpro also completed its previously announced private investment in public equity, issuing 1,122,467 shares of Common Stock and 2,244,934
Incentive Shares in the PIPE Offering, which raised $7.0 million in net proceeds.
Our Common Stock and our Public
Warrants are listed on the Nasdaq Global Market under the symbols "ABP" and "ABPWW," respectively. On December
20, 2024, the closing price of our Common Stock was $2.07 and the closing price for our Public Warrants was $0.10.
There is no assurance that
the holders of the Warrants will elect to exercise any or all of the Warrants, which could impact our liquidity position. To the extent
that the Warrants are exercised on a "cashless basis," the amount of cash we would receive from the exercise of the Warrants
will decrease. We believe the likelihood that Warrant holders will exercise their Warrants, and therefore the amount of cash proceeds
that we would receive is, among other things, dependent upon the market price of our Common Stock. If the market price for our Common
Stock is less than the applicable exercise price of $11.50, subject to adjustment as described herein, we believe such holders will be
unlikely to exercise their Warrants. Based on our current operating plan, our existing cash and cash equivalents, together with the proceeds
from the Business Combination and the PIPE Offering, will be insufficient to meet our anticipated cash needs for working capital, financial
liabilities and capital expenditures for the next 12 months from the date of this filing. To finance our operations beyond that point,
we would need to raise additional capital, which cannot be assured. The Company does not believe this offering will have a significant
impact on our ability to raise additional financing, although it may impact the per share price and shares issued in any capital raise.
1
The Common Stock being registered for resale in this prospectus represent
a substantial percentage of our public float and of our outstanding Common Stock. The number of shares being registered in this prospectus
(which include shares issuable upon exercise of the Warrants and shares issuable pursuant to the SEPA) represents approximately 117.0%
of the total Common Stock outstanding as of December 23, 2024, which was 51,815,765 shares of Common Stock. In addition, the securities
beneficially owned by the Sponsor represent approximately 6.7% of the total Common Stock outstanding, and the Sponsor will have the ability
to sell all of its shares pursuant to the registration statement of which this prospectus forms a part so long as it is available for
use and the 12 month lockup has expired. The sale of the securities being registered in this prospectus, or the perception in the market
that such sales may occur, could result in a significant decline in the public trading price of our Common Stock.
The rights of holders of
our Common Stock and Warrants are governed by our second amended and restated certificate of incorporation (the "
Charter
")
and our amended and restated bylaws (the "
Bylaws
") and the General Corporation Law of the State of Delaware (the "
DGCL
"),
and in the case of the Warrants, the Public Warrant Agreement, dated January 13, 2022, by and between ACAB and Continental Stock Transfer &
Trust Company (the "
Public Warrant Agreement
") and the Private Warrant Agreement, dated January 13, 2022, by and between
ACAB and Continental Stock Transfer & Trust Company (the "
Private Warrant Agreement
"). See the section entitled
"
Description of Capital Stock
."
Implications of Being an Emerging Growth Company
We are an "emerging
growth company" as defined in Section 2(a) of the Securities Act of 1933, as amended (the "Securities Act"),
as modified by the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"). As an emerging growth company, we may benefit
from specified reduced disclosure and other requirements that are otherwise applicable generally to public companies. These provisions
include:
●
presentation
of only two years of audited financial statements and only two years of related management's discussion and analysis of financial
condition and results of operations in this prospectus;
●
reduced
disclosure about our executive compensation arrangements;
●
no
non-binding stockholder advisory votes on executive compensation or golden parachute arrangements;
●
exemption
from any requirement of the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the
auditor's report providing additional information about the audit and the financial statements (i.e., an auditor discussion and
analysis); and
●
exemption
from the auditor attestation requirement in the assessment of our internal control over financial reporting.
We may benefit from these
exemptions until we cease to be an emerging growth company. We will cease to be an emerging growth company upon the earliest of: (a)
the last day of the fiscal year in which we have total annual gross revenues of $1.235 billion or more; (b) the last day of the fiscal
year following the fifth anniversary of the date of the completion of the ACAB IPO; (c) the date on which we have issued more than $1
billion in nonconvertible debt during the previous three years; or (d) the date on which we are deemed to be a "large accelerated"
filer under the Securities Exchange Act of 1934, as amended (the "
Exchange Act
"). We may choose to benefit from
some but not all of these reduced disclosure obligations in future filings. If we do, the information that we provide stockholders may
be different than you might get from other public companies in which you hold stock.
2
Summary Risk Factors
You should consider all the
information contained in this prospectus before making a decision to invest in our Securities. In particular, you should consider the
risk factors described under "
Risk Factors
" beginning on page 7. Such risks include, but are not limited to, the
following risks with respect to the Company subsequent to the Business Combination:
Risks Related to Our Business
and Industry
●
Our
management has concluded that uncertainties around our ability to raise additional capital raise substantial doubt about our ability
to continue as a going concern, including drug development;
●
Drug
development is a highly uncertain undertaking and involves a substantial degree of risk;
●
Our
product candidates are in early stages of development and have never been tested in a human subject. Our product candidates may fail
in development or suffer delays that materially and adversely affect their commercial viability;
●
The
market may not be receptive to our product candidates based on our novel therapeutic modality, and we may not generate any revenue from
the sale or licensing of product candidates;
●
We
will need substantial additional funds to advance development of our product candidates, and we cannot guarantee that we will have sufficient
funds available in the future to develop and commercialize our current or future product candidates;
●
Through
our AbMed subsidiary, we have in-licensed certain intellectual property rights relating to ABP-201 from MedImmune
Limited, or MedImmune (now AstraZeneca), and are in breach of the terms of our license agreement with MedImmune/AstraZeneca;
●
We
have entered, and may in the future seek to enter, into collaborations with third parties for the development and commercialization of
our product candidates. If such collaborations are not successful, we may not be able to capitalize on the market potential of our product
candidates;
●
If
our partners cease development efforts under our existing or future collaborations, or if any of those agreements is terminated, these
collaborations may fail to lead to commercial products, and we may never receive milestone payments or future royalties under these agreements;
●
If
third parties on which we intend to rely on to conduct certain preclinical studies, or any future clinical trials, do not perform as
contractually required, fail to satisfy regulatory or legal requirements or miss expected deadlines, our development program could be
delayed with material and adverse effects on our business, financial condition, results of operations and prospects;
●
Because
we may rely on third-party manufacturing and supply partners for preclinical and clinical development materials, our supply may become
limited or interrupted or may not be of satisfactory quantity or quality;
●
We
face competition from entities that have developed or may develop product candidates for the treatment of the diseases that we are initially
targeting, including companies developing novel treatments and technology platforms;
●
Any
inability to attract and retain qualified key management, technical personnel and employees would impair our ability to implement our
business plan; and
●
Litigation
and legal proceedings may substantially increase our costs and harm our business.

Risks Related to Intellectual
Property

RISK FACTORS
You should carefully consider
all the following risk factors, together with all of the other information included or incorporated by reference in this prospectus,
including the consolidated financial statements and the accompanying notes and matters addressed in the section titled "Cautionary
Note Regarding Forward-Looking Statements," in evaluating an investment in the Common Stock or Warrants. The following risk factors
apply to the business and operations of New Abpro and its consolidated subsidiaries. The occurrence of one or more of the events or circumstances
described in these risk factors, alone or in combination with other events or circumstances, may adversely affect the ability to realize
the anticipated benefits of the Business Combination and may have an adverse effect on the business, cash flows, financial condition
and results of operations of New Abpro following the consummation of the Business Combination. We may face additional risks and uncertainties
that are not presently known to us or that we currently deem immaterial, which may also impair our business, cash flows, financial condition
and results of operations.
Risks Related to Our Business and Industry
Our management has concluded that uncertainties
around our ability to raise additional capital raise substantial doubt about our ability to continue as a going concern, including drug
development. We will require additional financing to fund our future operations. Any failure to obtain additional capital when needed
on acceptable terms, or at all, could force us to delay, limit, reduce or terminate our operations.
We have concluded that we
do not have sufficient cash to fund our operations and drug development and to meet our obligations as they become due within one year
from the date that our consolidated financial statements are issued and as a result, there is substantial doubt about our ability to
continue as a going concern. Our ability to continue as a going concern is an issue raised as a result of ongoing operating losses and
a lack of financing commitments to meet cash requirements, and is subject to our ability to generate a profit or obtain appropriate financing
from outside sources, including obtaining additional funding from the sale of our securities or obtaining loans from third parties where
possible. We will need to raise additional capital to fund our operations and drug development. We cannot assure you that we will be
able to raise additional capital on commercially reasonable terms or at all. The perception that we may not be able to continue as a
going concern may materially limit our ability to raise additional funds through the issuance of new debt or equity securities or otherwise
and no assurance can be given that sufficient funding will be available when needed to allow us to continue as a going concern. This
perception may also make it more difficult to operate our business due to concerns about our ability to meet our contractual obligations.
If we cannot continue as a going concern, we may have to liquidate our assets and may receive less than the value at which those assets
are carried on our financial statements, and it is likely that our stockholders may lose some or all of their investment in us.
Drug development is a highly uncertain
undertaking and involves a substantial degree of risk. We are a preclinical stage biopharmaceutical company with a history of losses,
expect to continue to incur significant losses for the foreseeable future and may never achieve or maintain profitability, which could
result in a decline in the market value of our common stock.
Pharmaceutical and biopharmaceutical
product development is a highly speculative undertaking and involves a substantial degree of risk. We are a preclinical stage biopharmaceutical
company with a history of losses. Since our inception, we have devoted our resources to the development of antibody product candidates,
our technologies and our
DiversImmune
®
and
MultiMab
TM
platforms. We are not
profitable and have had significant operating losses since our inception. As of September 30, 2024, we had an accumulated deficit of $109.5
million. For the nine months ended September 30, 2024 and the year ended December 31, 2023, our net loss was $3.9 million and
$11.7 million, respectively. Substantially all of our losses have resulted from expenses incurred in connection with our collaboration
agreements, research and development programs and from general and administrative costs associated with our operations. We continue to
incur significant research and development ("R&D") and other expenses related to ongoing operations and expect to incur
losses for the foreseeable future.
Preclinical studies and clinical
trials are long, expensive and unpredictable processes that can be subject to extensive delays. We cannot guarantee that any clinical
trials will be conducted as planned or completed on schedule, if at all. It may take several years and require significant expenditures
to complete the preclinical studies and clinical trials necessary to commercialize a product candidate, and delays or failure are inherently
unpredictable and can occur at any stage. We may also be required to conduct additional clinical trials or other testing of our product
candidates beyond the trials and testing that we contemplate, which may lead to us incurring additional unplanned costs or result in
delays in clinical development. In addition, we may be required to redesign or otherwise modify our plans with respect to an ongoing
or planned clinical trial, and changing the design of a clinical trial can be expensive and time consuming. An unfavorable outcome in
one or more trials would be a major setback for our product candidates and for us. An unfavorable outcome in one or more trials may require
us to delay, reduce the scope of or eliminate one or more product development programs, which could have a material adverse effect on
our business, financial position, results of operations and future growth prospects.
7
Our product candidates are
in early stages of development, and we are subject to the risks of failure inherent in the development of product candidates based on
novel technologies. We believe that we are at a sufficiently mature development stage with both lead candidates that given adequate funding
and, in the case of ABP-102, continued successful collaboration with Celltrion, these programs would be able to enter clinical trials
in 2026 (in the case of ABP-102 and ABP-201). However, there can be no guarantee that both or either will do so, and to date, we have
not yet had any discussions with the U.S. Food and Drug Administration (the "FDA") regarding the clinical trial design for
our lead product candidates. We have never generated any revenue from product sales, and have not obtained regulatory approval for any
of our product candidates. Accordingly, you should consider our prospects in light of the costs, uncertainties, delays, and difficulties
frequently encountered by preclinical stage biopharmaceutical companies such as ours. We currently do not expect to generate any near-term
revenue other than from certain milestone payments under the collaboration agreements relating to our two lead antibodies. We do not
expect to generate any revenue from product sales for the foreseeable future, and we expect to continue to incur significant operating
losses for the foreseeable future due to the cost of research and development, preclinical studies and clinical trials, and the regulatory
approval process for our product candidates. We expect our net losses to increase substantially as we enter into clinical development
of our lead programs. However, the amount of our future losses is uncertain. Our ability to achieve profitability, if ever, will depend
on, among other things, our, and our existing or future partners, successfully developing product candidates, obtaining regulatory approvals
to market and commercialize product candidates, achieving contractual milestones under our collaboration agreements, manufacturing any
approved products on commercially reasonable terms, realizing royalties on any approved products under our collaboration agreements,
establishing a sales and marketing organization or suitable third-party alternatives for any approved product and raising sufficient
funds to finance business activities. If we, and our existing or future partners, are unable to develop our technologies and commercialize
one or more of our product candidates or if sales revenue from any product candidate that receives approval is insufficient, we will
not achieve profitability, which will have a material and adverse effect on our business, financial condition, results of operations
and prospects. Any predictions you make about our future success or viability may not be as accurate as they could be if we had a history
of successfully developing and commercializing pharmaceutical products.
Our product candidates are in early stages
of development and have never been tested in a human subject. Our product candidates may fail in development or suffer delays that materially
and adversely affect their commercial viability.
We have no products on the
market and all of our product candidates, including ABP-102, for the potential treatment of breast and gastric cancers, and ABP-201, for the
potential treatment of wet age-related macular degeneration (Wet AMD) and diabetic macular edema (DME), have not yet entered
clinical trials. In particular, none of our product candidates has ever been tested in a human subject. Our ability to achieve and sustain
profitability depends on obtaining regulatory approvals for and successfully commercializing our product candidates, either alone or
with third parties. Before obtaining regulatory approval for the commercial distribution of our product candidates, we or an existing
or future partner must conduct extensive preclinical studies and clinical trials to demonstrate the safety and efficacy in humans of
our product candidates.
We may not have the financial resources to continue
development of, or to modify existing or enter into new collaborations for, a product candidate if we experience any issues that delay
or prevent regulatory approval of, or our ability to commercialize, product candidates, including:
●
negative
or inconclusive results from our clinical trials or the clinical trials of others for product candidates similar to ours, leading to
a decision or requirement to conduct additional preclinical studies or clinical trials or abandon a program;
●
product-related
side effects experienced by participants in our clinical trials or by individuals using drugs or therapeutic antibodies similar to our
product candidates;
●
delays
in submitting investigational new drug applications (each an "IND") or comparable foreign applications or delays or failure
in obtaining the necessary approvals from regulators to commence a clinical trial, or a suspension or termination of a clinical trial
once commenced;
●
conditions
imposed by the FDA, or comparable foreign authorities regarding the scope or design of our clinical trials;
●
delays
in enrolling research subjects in clinical trials;
●
high drop-out rates
of research subjects;
●
inadequate
supply or quality of product candidate components or materials or other supplies necessary for the conduct of our clinical trials;
●
greater
than anticipated clinical trial costs;
●
poor
effectiveness of our product candidates during clinical trials;
8
●
unfavorable
FDA or other regulatory agency inspection and review of a clinical trial site;
●
failure
of our third-party contractors or investigators to comply with regulatory requirements or otherwise meet their contractual obligations
in a timely manner, or at all; and
●
delays
and changes in regulatory requirements, policy and guidelines, including the imposition of additional regulatory oversight around clinical
testing generally or with respect to our technology in particular; or
●
varying
interpretations of data by the FDA and similar foreign regulatory agencies.
Our approach to the discovery and development
of our antibodies using our DiversImmune
®
and MultiMab
TM
may not result in a marketable therapeutic
antibody product.
The scientific research that
forms the basis of our efforts to discover product candidates based on our
DiversImmune
®
and
MultiMab
TM
platforms
is ongoing. Further, the scientific evidence to support the feasibility of developing therapeutic antibodies based on our platforms is
both preliminary and limited. We may not be correct in our assumptions about the superiority of our platforms to competing technologies.
If our
DiversImmune
®
and
MultiMab
TM
platforms are not able to develop next-generation
approved antibody constructs that are effective against clinically validated targets at the necessary speed or scale, it could have a
material and adverse effect on our business, financial condition, results of operations and prospects.
Our next-generation bispecific antibodies
may not demonstrate the therapeutic effects of, or benefits at least comparable to, monospecific antibodies that we anticipate once tested
in humans.
None of our product candidates
have been tested in humans. We may ultimately discover that our product candidates do not possess certain properties that we believe
are helpful for therapeutic effectiveness, including strong binding for increased efficacy and increased binding sites for increased
potency, and safety, including reduced immunogenicity and optimized binding domain position, or dosing, including a longer circulating
half-life resulting in reduced dosing required. For example, when administered in a human, we may find that our product candidates perform
differently than in preclinical studies. We currently have only limited preclinical data, and no conclusive evidence, to suggest that
we can introduce these favorable properties into any of our product candidates. We may spend substantial funds attempting to introduce
these properties and may never succeed in doing so. In addition, certain of our product candidates may demonstrate different chemical
and pharmacological properties in patients than they do in laboratory studies. Although certain of our product candidates have successful
results in animal studies, they may not demonstrate the same chemical and pharmacological properties in humans and may interact with
human biological systems in unforeseen, ineffective or harmful ways. As a result, we may never succeed in developing a marketable product,
we may not become profitable and the value of our common stock will decline.
Further, we are aware of
only nine bispecific antibodies that have been approved by the FDA. As such, we believe the FDA has limited early experience with bispecific
antibody-based therapeutics, which may increase the complexity, uncertainty and length of the regulatory approval process for our product
candidates. For example, the FDA may require us to provide additional data to support our regulatory applications. We and our existing
or future partners may never receive approval to market and commercialize any product candidate. Even if we or an existing or future
partner obtains regulatory approval, the approval may be for targets, disease indications or patient populations that are not as broad
as we intended or desired or may require labeling that includes significant use or distribution restrictions or safety warnings. We or
an existing or future partner may be subject to post-marketing testing requirements to maintain regulatory approval. If any of our product
candidates prove to be ineffective, unsafe or commercially unviable, our entire pipeline could have little, if any, value, which could
require us to change our focus, approach to antibody development and reengineer the antibody. Any of these events could have a material
and adverse effect on our business, financial condition, results of operations and prospects.
9
The market may not be receptive to our
product candidates based on our novel therapeutic modality, and we may not generate any revenue from the sale or licensing of product
candidates.
Even if regulatory approval
is obtained for a product candidate, we may not generate or sustain revenue from sales of the product due to factors such as whether
the product can be sold at a competitive cost and otherwise accepted in the market. The antibodies we are developing use relatively new
technologies. Market participants with significant influence over acceptance of new treatments, such as physicians and third-party payors,
may not adopt a product or treatment based on our platforms and technologies, and we may not be able to convince the medical community
and third-party payors to accept and use, or to provide favorable reimbursement for, any product candidates developed by us or our existing
or future partners. Market acceptance of our product candidates will depend on, among other factors:
●
the
timing of our receipt of any marketing and commercialization approvals;
●
the
terms of any approvals and the countries in which approvals are obtained;
●
the
safety and efficacy of our product candidates;
●
the
prevalence and severity of any adverse side effects associated with our product candidates;
●
the
limitations or warnings contained in any labeling approved by the FDA or other regulatory authority;
●
the
relative convenience and ease of administration of our product candidates;
●
the
willingness of patients to accept any new methods of administration;
●
the
success of our physician education programs;
●
the
availability of adequate government and third-party payor reimbursement;
●
the
pricing of our products, particularly as compared to alternative treatments; and
●
the
availability of alternative effective treatments for the disease indications our product candidates are intended to treat and the relative
risks, benefits and costs of those treatments.
If any product candidate we commercialize fails
to achieve market acceptance, it could have a material and adverse effect on our business, financial condition, results of operations
and prospects.
We will need substantial additional funds
to advance development of our product candidates, and we cannot guarantee that we will have sufficient funds available in the future
to develop and commercialize our current or future product candidates.
The development of biopharmaceutical
product candidates is capital-intensive. If our product candidates enter and advance through preclinical studies and clinical trials,
we will need substantial additional funds to expand our development, regulatory, manufacturing, marketing and sales capabilities. We
have used substantial funds to develop our technology and product candidates and will require significant additional funds to conduct
further research and development and preclinical testing and clinical trials of our product candidates, to seek regulatory approvals
for our product candidates and to manufacture and market products, if any, that are approved for commercial sale. In addition, we expect
to incur additional costs associated with operating as a public company.
Because the length of time
and activities associated with successful research and development of our product candidates is highly uncertain, we are unable to estimate
the actual funds we will require for development and any approved marketing and commercialization activities. The timing and amount of
our operating expenditures will depend largely on:
●
the
timing and progress of preclinical and clinical development activities;
●
the
number and scope of preclinical and clinical programs we decide to pursue;
10
●
the
progress of the development efforts of parties with whom we have entered or may in the future enter into collaboration and research and
development agreements;
●
the
timing and amount of milestone or royalty payments we may receive under collaboration agreements;
●
our
ability to maintain our current licenses and research and development programs and to establish new collaborations;
●
the
costs involved in obtaining, maintaining, enforcing and defending patents and other intellectual property rights;
●
the
cost and timing of regulatory approvals; and
●
our
efforts to enhance operational systems and hire additional personnel, including personnel to support development of our product candidates
and satisfy our obligations as a public company.
If we are unable to obtain
funding on a timely basis or on acceptable terms, we may have to delay, reduce or terminate our research and development programs and
preclinical studies or clinical trials, if any, limit strategic opportunities or undergo reductions in our workforce or other corporate
restructuring activities. We also could be required to seek funds through arrangements with partners or others that may require us to
relinquish rights to some of our technologies or product candidates that we would otherwise pursue on our own. We do not expect to realize
revenue from sales of products or royalties from licensed products in the foreseeable future, if at all, and unless and until our product
candidates are clinically tested, approved for commercialization and successfully marketed. To date, we have primarily financed our operations
through the sale of debt and equity securities and payments received under our collaboration agreements. We will be required to seek
additional funding in the future and currently intend to do so through additional collaborations, public or private equity offerings
or debt financings, credit or loan facilities or a combination of one or more of these funding sources. Our ability to raise additional
funds will depend on financial, economic and other factors, many of which are beyond our control. Additional funds may not be available
to us on acceptable terms or at all. If we raise additional funds by issuing equity securities, our stockholders will suffer dilution
and the terms of any financing may adversely affect the rights of our stockholders. In addition, as a condition to providing additional
funds to us, future investors may demand, and may be granted, rights superior to those of existing stockholders. Debt financing, if available,
is likely to involve restrictive covenants limiting our flexibility in conducting future business activities, and, in the event of insolvency,
debt holders would be repaid before holders of our equity securities received any distribution of our corporate assets.
We may expend our limited resources to
pursue a particular product candidate and fail to capitalize on product candidates that may be more profitable or for which there is
a greater likelihood of success.
Because we have limited financial
and managerial resources, we focus on specific product candidates. As a result, we may forgo or delay pursuit of opportunities with other
product candidates that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize
on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs
and product candidates for specific indications may not yield any commercially viable product candidates. If we do not accurately evaluate
the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate
through partnership, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain
sole development and commercialization rights to such product candidate.
Through our AbMed subsidiary, we have in-licensed certain
intellectual property rights relating to ABP-201 from MedImmune Limited, or MedImmune (now AstraZeneca), and are in breach
of the terms of our license agreement with MedImmune/AstraZeneca.
The
license agreement with MedImmune/AstraZeneca provides for a research plan with target dates for an IND application (July 2021) and Phase
II commencement (December 2022), These target dates were not met, which gives MedImmune/AstraZeneca a termination right. We communicated
with Medimmune/AstraZeneca in September 2021 regarding the development timeline, but no further discussion has been held. We continue
to provide annual development reports to MedImmune/AstraZeneca, most recently in January 2024.
11
We do not expect a material
impact on our business if MedImmune/AstraZeneca terminates this agreement. This license was originally entered into in connection with
the development of ABP-200, which we are no longer developing. We believe that we do not need the intellectual property licensed under
that agreement for the development and eventual commercialization of ABP-201 or any of our other programs. The risks described elsewhere
pertaining to our patents and other intellectual property rights also apply to the intellectual property rights that we license from
third parties, and any failure by us or our licensors to obtain, maintain, defend and enforce these rights could have a material adverse
effect on our business.
We have entered, and may in the future
seek to enter, into collaborations with third parties for the development and commercialization of our product candidates. If such collaborations
are not successful, we may not be able to capitalize on the market potential of our product candidates.
ABP-102 is being developed
and commercialized through a worldwide strategic partnership with Celltrion Inc. ("
Celltrion
") (KRX:068270), a leading
Korean biopharmaceutical company headquartered in Incheon, South Korea. ABP-201 is being developed and commercialized through
a territorial partnership with Abpro Bio International, Inc. ("
Abpro Bio
"), a subsidiary of Abpro Bio Co. Ltd (KOSDAQ:195990),
a company headquartered in Daegu, South Korea. ABP-150 is being developed under a collaboration agreement with Nanjing Chia
Tai Tianqing Pharmaceutical Co., Ltd ("
NJCTTQ
"), headquartered in Nanjing, China.
We will continue to explore
strategic and geographic-oriented partnerships that provide us with near-term economic benefits where we retain product rights to key
strategic markets. More generally, we may also seek out third-party partners, such as biotech companies, pharmaceutical companies and
distributors, for marketing, distribution, development, licensing or broader arrangements to complement our own capabilities.
Our ability to generate revenues
from our existing collaborations for licensing and co-development of our product candidates and any future similar arrangements,
will depend on our ability to successfully develop the product candidates and receive necessary product approvals for commercialization
in the agreed territories. We have limited ability to control the actions of our joint development and any other third-party partners,
and successful product development will depend to some extent on such third parties to perform the functions assigned to them in our
contracts.
Collaborations involving
our product candidates currently pose, and will continue to pose, the following risks to us:
●
third
parties have significant discretion in determining the efforts and resources that they will apply to these collaborations;
●
third
parties may not pursue development and commercialization of our product candidates or may elect not to continue or renew development
or commercialization programs based on preclinical study or clinical trial results, changes in strategic focus or available funding,
or external factors such as an acquisition that diverts resources or creates competing priorities;
●
third
parties may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a product
candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing;
●
third
parties could independently develop, or develop with other third parties, products that compete directly or indirectly with our product
candidate if the partners believe that competitive products are more likely to be successfully developed or can be commercialized under
terms that are more economically attractive than ours;
●
third
parties with marketing and distribution rights to one or more products may not commit sufficient resources to the marketing and distribution
of such product or products;
12
●
third
parties may not properly maintain, enforce or defend our intellectual property rights or may use our proprietary information in such
a way as to invite litigation or other legal proceedings that could jeopardize, invalidate or render unenforceable our intellectual property
or proprietary information or expose us to litigation, other legal proceedings or potential liability;
●
third
parties may infringe, misappropriate or violate the intellectual property rights of others, which may expose us to litigation, other
legal proceedings and potential liability;
●
third
parties may engage in misconduct, including non-compliance with regulatory requirements, that may result in governmental investigations
or other actions or lawsuits against us or the third party;
●
disputes
may arise between our third-party collaborators and our company that result in the delay or termination of the research, development
or commercialization of our product candidate or that result in costly litigation or arbitration that diverts management attention and
resources; and
●
collaborations
may be terminated and, if terminated, may result in a need for additional capital to pursue further development or commercialization
of the applicable product candidates.
Collaboration agreements
may not lead to development or commercialization of our product candidates in the most efficient manner or at all. If a partner of ours
were to be involved in a business combination, the continued pursuit and emphasis on our product development or commercialization program
could be delayed, diminished or terminated. Any failure of our existing and any future collaborations would negatively affect our business
plans and strategy for our product candidate pipeline, which could have a material and adverse effect on our business, financial condition,
results of operations and prospects.
If our partners cease development efforts
under our existing or future collaborations, or if any of those agreements is terminated, these collaborations may fail to lead to commercial
products, and we may never receive milestone payments or future royalties under these agreements.
A portion of our future revenue
and cash resources is expected to be derived from our license and collaboration agreements. Revenue from these collaborations depends
upon continuation of the collaborations, reimbursement of development costs, the achievement of milestones and royalties, if any, derived
from future products developed from our research. If we are unable to successfully advance the development of our product candidates
or achieve milestones, revenue and cash resources from milestone payments under our collaboration agreements will be substantially less
than expected.
In addition, to the extent
that any of our existing or future partners were to terminate a collaboration agreement, we may be forced to independently develop these
product candidates, including funding preclinical studies or clinical trials, assuming marketing and distribution costs and maintaining,
enforcing and defending intellectual property rights, or, in certain instances, abandon product candidates altogether, any of which could
result in a change to our business plan and a material and adverse effect on our business, financial condition, results of operations
and prospects.
We may not successfully engage in strategic
transactions, including any additional collaborations we seek, which could adversely affect our ability to develop and commercialize
product candidates, impact our cash position, increase our expense, and present significant distractions to our management.
From time to time, we may
consider strategic transactions, such as additional collaborations, acquisitions of companies, asset purchases, joint ventures and out- or in-licensing of
product candidates or technologies. In particular, we will evaluate and, if strategically attractive, seek to enter into additional collaborations,
including with major biotechnology or biopharmaceutical companies or hospitals. The competition for partners is intense, and the negotiation
process is time-consuming and complex. Any new collaboration may be on terms that are not optimal for us, and we may not be able to maintain
any new collaboration if, for example, development or approval of a product candidate is delayed, sales of an approved product candidate
do not meet expectations or the partner terminates the collaboration. Any such collaboration, or other strategic transaction, may require
us to incur non-recurring or other charges, increase our near- and long-term expenditures and pose significant integration
or implementation challenges or disrupt our management or business. These transactions would entail numerous operational and financial
risks, including:
●
exposure
to unknown liabilities;
●
disruption
of our business and diversion of our management's time and attention in order to manage a collaboration or develop acquired products,
product candidates or technologies;
13
●
incurrence
of substantial debt or dilutive issuances of equity securities to pay transaction consideration or costs;
●
higher
than expected collaboration, acquisition or integration costs, write-downs of assets or goodwill or impairment charges, increased amortization
expenses;
●
difficulty
and cost in facilitating the collaboration or combining the operations and personnel of any acquired business;
●
impairment
of relationships with key suppliers, manufacturers or customers of any acquired business due to changes in management and ownership;
and
●
the
inability to retain key employees of any acquired business.
Accordingly, although there
can be no assurance that we will undertake or successfully complete any transactions of the nature described above, any transactions
that we do complete may be subject to the foregoing or other risks and have a material and adverse effect on our business, financial
condition, results of operations and prospects. Conversely, any failure to enter any additional collaboration or other strategic transaction
that would be beneficial to us could delay the development and potential commercialization of our product candidates and have a negative
impact on the competitiveness of any product candidate that reaches market.
We may acquire assets or form strategic
alliances in the future, and we may not realize the benefits of such acquisitions.
We may acquire additional
technologies and assets, form strategic alliances or create joint ventures with third parties that we believe will complement or augment
our existing business. If we acquire assets with promising markets or technologies, we may not be able to realize the benefit of acquiring
such assets if we are unable to successfully integrate them with our existing technologies. We may encounter numerous difficulties in
developing, manufacturing and marketing any new products resulting from a strategic alliance or acquisition that delay or prevent us
from realizing their expected benefits or enhancing our business. We cannot assure you that, following any such acquisition, we will
achieve the expected synergies to justify the transaction.
If third parties on which we intend to
rely on to conduct certain preclinical studies, or any future clinical trials, do not perform as contractually required, fail to satisfy
regulatory or legal requirements or miss expected deadlines, our development program could be delayed with material and adverse effects
on our business, financial condition, results of operations and prospects.
We intend to rely on third-party
clinical investigators, contract research organizations ("CROs"), clinical data management organizations and consultants
to design, conduct, supervise and monitor certain preclinical studies of our product candidates and will do the same for any clinical
trials. Because we intend to rely on these third parties and will not have the ability to conduct certain preclinical studies or clinical
trials independently, we will have less control over the timing, quality and other aspects of such preclinical studies and clinical trials
than we would have had we conducted them on our own. These investigators, CROs and consultants will not be our employees and we will
have limited control over the amount of time and resources that they dedicate to our programs. These third parties may have contractual
relationships with other entities, some of which may be our competitors, which may draw time and resources from our programs. The third
parties with which we may contract might not be diligent, careful or timely in conducting our preclinical studies or clinical trials,
resulting in the preclinical studies or clinical trials being delayed or unsuccessful.
14
If we cannot contract with
acceptable third parties on commercially reasonable terms, or at all, or if these third parties do not carry out their contractual duties,
satisfy legal and regulatory requirements for the conduct of preclinical studies or clinical trials or meet expected deadlines, our clinical
development programs could be delayed and otherwise adversely affected. In all events, we will be responsible for ensuring that each
of our preclinical studies and clinical trials are conducted in accordance with the general investigational plan and protocols for the
trial. The FDA requires preclinical studies to be conducted in accordance with good laboratory practices, or GLPs, and clinical trials
to be conducted in accordance with good clinical practices ("GCPs"), including for designing, conducting, recording and reporting
the results of preclinical studies and clinical trials to ensure that data and reported results are credible and accurate and that the
rights, integrity and confidentiality of clinical trial participants are protected. Our reliance on third parties that we do not control
will not relieve us of these responsibilities and requirements. Any adverse development or delay in our clinical trials could have a
material and adverse effect on our business, financial condition, results of operations and prospects.
Because we may rely on third-party manufacturing
and supply partners for preclinical and clinical development materials, our supply may become limited or interrupted or may not be of
satisfactory quantity or quality.
We produce only small-scale
quantities of our antibodies and reagents for characterization, in vivo and in vitro assessment. We may rely on third-party contract
manufacturers to manufacture our preclinical and clinical trial product supplies. We do not currently own manufacturing facilities for
producing such supplies. There can be no assurance that our preclinical or clinical development product supplies will not be limited
or interrupted, or will be of satisfactory quality or continue to be available at acceptable prices. In particular, any replacement of
our manufacturers could require significant effort and expertise because there may be a limited number of qualified replacements.
The manufacturing process
for a product candidate is subject to FDA and foreign regulatory authority review. Suppliers and manufacturers must meet applicable manufacturing
requirements and undergo rigorous facility and process validation tests required by regulatory authorities in order to comply with regulatory
standards, such as current Good Manufacturing Practices ("cGMPs"). In the event that any of our manufacturers fails to comply
with such requirements or to perform its obligations to us in relation to quality, timing or otherwise, or if our supply of components
or other materials becomes limited or interrupted for other reasons, we may be forced to manufacture the materials ourselves, for which
we currently do not have the capabilities or resources, or enter into an agreement with another third party, which we may not be able
to do on reasonable terms, if at all. In some cases, the technical skills or technology required to manufacture our product candidates
may be unique or proprietary to the original manufacturer and we may have difficulty transferring such skills or technology to another
third party and a feasible alternative may not exist. These factors would increase our reliance on such manufacturer or require us to
obtain a license from such manufacturer in order to have another third party manufacture our product candidates. If we are required to
change manufacturers for any reason, we will be required to verify that the new manufacturer maintains facilities and procedures that
comply with quality standards and with all applicable regulations and guidelines. The delays associated with the verification of a new
manufacturer could negatively affect our ability to develop product candidates in a timely manner or within budget.
We expect to rely on third-party
manufacturers if we receive regulatory approval for any product candidate. To the extent that we have existing, or enter into future,
manufacturing arrangements with third parties, we will depend on these third parties to perform their obligations in a timely manner
consistent with contractual and regulatory requirements, including those related to quality control and assurance. If we are unable to
obtain or maintain third-party manufacturing for product candidates, or to do so on commercially reasonable terms, we may not be able
to develop and commercialize our product candidates successfully. Our or a third party's failure to execute on our manufacturing
requirements and comply with cGMPs could adversely affect our business in a number of ways, including:
●
an
inability to initiate or continue clinical trials of product candidates under development;
●
delay
in submitting regulatory applications, or receiving regulatory approvals, for product candidates;
●
loss
of the cooperation of an existing or future partner;
15
●
subjecting
third-party manufacturing facilities or our manufacturing facilities to additional inspections by regulatory authorities;
●
requirements
to cease distribution or to recall batches of our product candidates; and
●
in
the event of approval to market and commercialize a product candidate, an inability to meet commercial demands for our products.
Our third-party manufacturers may be unable
to successfully scale manufacturing of our product candidates in sufficient quality and quantity, which would delay or prevent us from
developing our product candidates and commercializing approved products, if any.
In order to conduct clinical
trials, we will need to manufacture large quantities of our product candidates. We may use third parties for our manufacturing needs.
Our manufacturing partners may be unable to successfully increase the manufacturing capacity for any of our product candidates in a timely
or cost-effective manner, or at all. In addition, quality issues may arise during scale-up activities. If our manufacturing
partners are unable to successfully scale the manufacture of our product candidates in sufficient quality and quantity, the development,
testing, and clinical trials of that product candidate may be delayed or infeasible, and regulatory approval or commercial launch of
any resulting product may be delayed or not obtained, which could significantly harm our business.
If the market opportunities for our product
candidates are smaller than we believe they are, our future product revenues may be adversely affected and our business may suffer.
Our understanding of both
the number of people who suffer from HER2+ breast and gastric cancers or other tumors that can be treated with VEGF inhibitors, is based
on estimates. These estimates may prove to be incorrect and new studies may reduce the estimated incidence or prevalence of these diseases.
The number of patients in the United States, Europe, or elsewhere may turn out to be lower than expected, may not be otherwise amenable
to treatment with our product candidates or patients may become increasingly difficult to identify and access, all of which would adversely
affect our business, financial condition, results of operations and prospects.
Further, there are several
factors that could contribute to making the actual number of patients who receive our potential product candidates less than the potentially
addressable market. These include the lack of widespread availability of, and limited reimbursement for, new therapies in many underdeveloped
markets.
We face competition from entities that
have developed or may develop product candidates for the treatment of the diseases that we are initially targeting, including companies
developing novel treatments and technology platforms. If these companies develop technologies or product candidates more rapidly than
we do or their technologies are more effective, our ability to develop and successfully commercialize product candidates may be adversely
affected.
The development and commercialization
of drugs and therapeutic biologics is highly competitive. We compete with a variety of multinational biopharmaceutical companies and
specialized biotechnology companies, as well as technology being developed at universities and other research institutions. Our competitors
are often larger and better funded. Our competitors have developed, are developing or will develop product candidates and processes competitive
with our product candidates and processes. Competitive therapeutic treatments include those that have already been approved and accepted
by the medical community and any new treatments that are currently in development or that enter the market. We believe that a significant
number of products are currently under development, and may become commercially available in the future, for the treatment of conditions
for which we may try to develop product candidates. There is intense and rapidly evolving competition in the biotechnology, biopharmaceutical
and antibody and immunoregulatory therapeutics fields. We believe that while our
DiversImmune
®
and
MultiMab
TM
platforms,
their associated intellectual property, the characteristics of our antibody product candidates in development, and our scientific and
technical know-how give us a competitive advantage in this space, competition from many sources remains. Given the number of
competitors, we strive to differentiate ourselves from them and contrast the perceived advantages of our technologies and product candidates.
There is a risk that some of our competitors will take issue with our positioning and make allegations regarding our company or our business
practices. Any such allegations could divert management's attention, which could have an adverse effect on our business.
16
We are aware of several companies
that are developing antibodies for the treatment of cancer and autoimmune diseases. Many of these companies are well-capitalized and,
in contrast to us, have significant clinical experience, and may include our existing or future partners. In addition, these companies
compete with us in recruiting scientific and managerial talent. Our success will partially depend on our ability to develop and protect
antibodies that are safer and more effective than competing products. Our commercial opportunity and success will be reduced or eliminated
if competing products that are safer, more effective, or less expensive than the antibodies we develop.
We expect to compete with
antibody developers, such as AnaptysBio, Inc., Bristol-Myers Squibb Company, Genmab A/S, Ichnos Glenmark Innovation, Janux Therapeutics,
Regeneron Pharmaceuticals, Inc., Roche AG, and Xencor Inc. If our lead product candidates are approved, they will compete with a range
of treatments that are either in development or currently marketed. For example, some of our product candidates will compete against traditional
cancer therapies, such as chemotherapy, as well as immune-based treatments for cancer, such as CAR T and TCR therapies, developed or currently
marketed by Bellicum Pharmaceuticals, Inc., Bluebird bio, Inc., Bristol-Myers Squibb Company, Cellectis S.A., Gilead Sciences, Inc., Novartis
AG, Precigen, Inc., AstraZeneca and Genentech, Inc. (a member of the Roche Group, or Genentech/Roche).
Many of our competitors have
significantly greater financial, technical, manufacturing, marketing, sales and supply resources or experience than we do. If we successfully
obtain approval for any product candidate, we will face competition based on many different factors, including the safety and effectiveness
of our products, the ease with which our products can be administered and the extent to which patients accept relatively new routes of
administration, the timing and scope of regulatory approvals for these products, the availability and cost of manufacturing, marketing
and sales capabilities, price, reimbursement coverage and patent position. Competing products could present superior treatment alternatives,
including by being more effective, safer, less expensive or marketed and sold more effectively than any products we may develop. Competitive
products may make any products we develop obsolete or noncompetitive before we recover the expense of developing and commercializing
our product candidates. Such competitors could also recruit our employees, which could negatively impact our level of expertise and our
ability to execute our business plan.
Any inability to attract and retain qualified
key management, technical personnel and employees would impair our ability to implement our business plan.
Our success largely depends on the continued service of key management,
advisors and other specialized personnel, including Ian Chan, our chief executive officer and co-founder, and Robert Markelewicz,
our chief medical officer. We have entered into written employment agreement with Ian Chan and have an offer letter with Robert Markelewicz.
 The loss of one or more members of our executive team, management team or other key employees or advisors could delay our research
and development programs and have a material and adverse effect on our business, financial condition, results of operations and prospects.
The relationships that our
key managers have cultivated within our industry make us particularly dependent upon their continued employment with us. We are dependent
on the continued service of our technical personnel because of the highly technical nature of our product candidates and technologies
and the specialized nature of the regulatory approval process. Because our management team and key employees are not obligated to provide
us with continued service, they could terminate their employment with us at any time without penalty. Our future success will depend
in large part on our continued ability to attract and retain other highly qualified scientific, technical and management personnel, as
well as personnel with expertise in clinical testing, manufacturing, governmental regulation and commercialization. We face competition
for personnel from other companies, universities, public and private research institutions, government entities and other organizations.
As of December 23, 2024,
we had 6 full-time employees, one full-time contractor, one part-time contractor, and 7 furloughed employees. Our focus on the development
of our product candidates will require adequate staffing. We may need to hire and retain new employees to execute our future clinical
development and manufacturing plans. We cannot provide assurance that we will be able to hire and/or retain adequate staffing levels to
develop our product candidates or run our operations and/ or to accomplish all of our objectives.
17
We may experience difficulties in managing
our growth and expanding our operations.
We have limited experience
in product development and have not begun clinical trials for any of our product candidates. As our product candidates enter and advance
through preclinical studies and any clinical trials, we will need to expand our development, regulatory and manufacturing capabilities
or contract with other organizations to provide these capabilities for us. We may also experience difficulties in the discovery and development
of new antibody product candidates using our
DiversImmune
®
and
MultiMab
TM
platforms
if we are unable to meet demand as we grow our operations. In the future, we also expect to have to manage additional relationships with
collaborators, suppliers and other organizations. Our ability to manage our operations and future growth will require us to continue
to improve our operational, financial and management controls, reporting systems and procedures. We may not be able to implement improvements
to our management information and control systems in an efficient or timely manner and may discover deficiencies in existing systems
and controls.
If any of our product candidates is approved
for marketing and commercialization and we are unable to develop sales, marketing and distribution capabilities on our own or enter into
agreements with third parties to perform these functions on acceptable terms, we will be unable to commercialize successfully any such
future products.
We currently have no sales,
marketing or distribution capabilities or experience. If any of our product candidates is approved, we will need to develop internal
sales, marketing and distribution capabilities to commercialize such products, which would be expensive and time-consuming, or enter
into partnerships with third parties to perform these services. If we decide to market our products directly, we will need to commit
significant financial and managerial resources to develop a marketing and sales force with technical expertise and supporting distribution,
administration and compliance capabilities. If we rely on third parties with such capabilities to market our products or decide to co-promote products
with partners, we will need to establish and maintain marketing and distribution arrangements with third parties, and there can be no
assurance that we will be able to enter into such arrangements on acceptable terms or at all. In entering into third-party marketing
or distribution arrangements, any revenue we receive will depend upon the efforts of the third parties and there can be no assurance
that such third parties will establish adequate sales and distribution capabilities or be successful in gaining market acceptance of
any approved product. If we are not successful in commercializing any product approved in the future, either on our own or through third
parties, our business, financial condition, results of operations and prospects could be materially and adversely affected.
Our future growth may depend, in part,
on our ability to operate in foreign markets, where we would be subject to additional regulatory burdens and other risks and uncertainties.
Our future growth may depend,
in part, on our ability to develop and commercialize our product candidates in foreign markets for which we may rely on partnership with
third parties. We are not permitted to market or promote any of our product candidates before we receive regulatory approval from the
applicable regulatory authority in that foreign market, and we may never receive such regulatory approval for any of our product candidates.
To obtain separate regulatory approval in many other countries, we must comply with numerous and varying regulatory requirements of such
countries regarding safety and efficacy and governing, among other things, clinical trials and commercial sales, pricing and distribution
of our product candidates, and we cannot predict success in these jurisdictions. If we obtain approval of our product candidates and
ultimately commercialize our product candidates in foreign markets, we would be subject to the risks and uncertainties, including the
burden of complying with complex and changing foreign regulatory, tax, accounting and legal requirements and the reduced protection of
intellectual property rights in some foreign countries.
Price controls imposed in foreign markets
may adversely affect our future profitability.
In some countries, particularly
member states of the European Union, the pricing of prescription drugs is subject to governmental control. In these countries, pricing
negotiations with governmental authorities can take considerable time after receipt of marketing approval for a product. In addition,
there can be considerable pressure by governments and other stakeholders on prices and reimbursement levels, including as part of cost
containment measures. Political, economic and regulatory developments may further complicate pricing negotiations, and pricing negotiations
may continue after reimbursement has been obtained. Reference pricing used by various European Union member states and parallel distribution,
or arbitrage between low-priced and high-priced member states, can further reduce prices. In some countries, we or future partners
may be required to conduct a clinical trial or other studies that compare the cost-effectiveness of our antibody product candidates to
other available therapies in order to obtain or maintain reimbursement or pricing approval. Publication of discounts by third-party payors
or authorities may lead to further pressure on the prices or reimbursement levels within the country of publication and other countries.
If reimbursement of any product candidate approved for marketing is unavailable or limited in scope or amount, or if pricing is set at
unsatisfactory levels, our business, financial condition, results of operations or prospects could be materially and adversely affected.
18
If any of our product candidates receives
marketing approval and we or others later identify undesirable side effects caused by the product candidate, our ability to market and
derive revenue from the product candidates could be compromised.
Undesirable side effects
caused by our product candidates could cause regulatory authorities to interrupt, delay or halt clinical trials and could result in a
more restrictive label or the delay or denial of regulatory approval by the FDA or other regulatory authorities. While we have not yet
initiated clinical trials for any of our product candidates, it is likely that there may be side effects associated with their use. Results
of our trials could reveal a high and unacceptable severity and prevalence of these or other side effects. In such an event, our trials
could be suspended or terminated and the FDA or comparable foreign regulatory authorities could order us to cease further development
of or deny approval of our product candidates for any or all targeted indications. Such side effects could also affect patient recruitment
or the ability of enrolled patients to complete the trial or result in potential product liability claims. Any of these occurrences may
materially and adversely affect our business, financial condition, results of operations and prospects.
Further, clinical trials
by their nature utilize a sample of the potential patient population. With a limited number of patients and limited duration of exposure,
rare and severe side effects of our product candidates may only be uncovered with a significantly larger number of patients exposed to
the product candidate.
In the event that any of
our product candidates receive regulatory approval and we or others identify undesirable side effects caused by one of our products,
any of the following adverse events could occur, which could result in the loss of significant revenue to us and materially and adversely
affect our results of operations and business:
●
regulatory
authorities may withdraw their approval of the product or seize the product;
●
we
may be required to recall the product or change the way the product is administered to patients;
●
additional
restrictions may be imposed on the marketing of the particular product or the manufacturing processes for the product or any component
thereof;
●
we
may be subject to fines, injunctions or the imposition of civil or criminal penalties;
●
regulatory
authorities may require the addition of labeling statements, such as a "black box" warning or a contraindication;
●
we
may be required to create a medication guide outlining the risks of such side effects for distribution to patients;
●
we
could be sued and held liable for harm caused to patients;
●
the
product may become less competitive; and
●
our
reputation may suffer.
Litigation and legal proceedings may substantially
increase our costs and harm our business.
We have been, are, and may
in the future become, party to lawsuits and legal proceedings including, without limitation, actions and proceedings in the ordinary
course of business relating to our collaboration partners, directors, officers, stockholders, intellectual property rights, employment
matters and the safety or efficacy of our products, which will cause us to incur legal fees and other costs related thereto, including
potential expenses for the reimbursement of legal fees of officers and directors under indemnification obligations. See "
Legal
Proceedings
."
19
The expense of defending
against such litigation and legal proceedings may be significant and there can be no assurance that we will be successful in any defense.
Further, the amount of time that may be required to resolve such lawsuits or legal proceedings is unpredictable, and these actions may
divert management's attention from the day-to-day operations of our business, which could adversely affect our business,
results of operations, and cash flows. Our insurance carriers may deny coverage, may be inadequately capitalized to pay on valid claims,
or our policy limits may be inadequate to fully satisfy any damage awards or settlements. If this were to happen, the payment of any
such awards could have a material adverse effect on our consolidated operations, cash flows and financial position. Additionally, any
such claims, whether or not successful, could damage our reputation and business. Litigation and legal proceedings are subject to inherent
uncertainties, and an adverse result in such matters that may arise from time to time could have a material adverse effect on our business,
results of operations, and financial condition.
Our business entails a significant risk
of product liability and our ability to obtain sufficient insurance coverage could have a material and adverse effect on our business,
financial condition, results of operations and prospects.
As we move into conducting
clinical trials of our product candidates, we will be exposed to significant product liability risks inherent in the development, testing,
manufacturing and marketing of antibody treatments. Product liability claims could delay or prevent completion of our development programs.
If we succeed in marketing products, such claims could result in an FDA investigation of the safety and effectiveness of our products,
our manufacturing processes and facilities or our marketing programs and potentially a recall of our products or more serious enforcement
action, limitations on the approved indications for which they may be used or suspension or withdrawal of approvals. Regardless of the
merits or eventual outcome, liability claims may also result in decreased demand for our products, injury to our reputation, costs to
defend the related litigation, a diversion of management's time and our resources, substantial monetary awards to trial participants
or patients and a decline in our stock price. We currently do not have product liability insurance and will need to obtain such insurance
prior to marketing any of our product candidates. Any insurance we have or may obtain may not provide sufficient coverage against potential
liabilities. Furthermore, clinical trial and product liability insurance is becoming increasingly expensive. As a result, our partners
or we may be unable to obtain sufficient insurance at a reasonable cost to protect us against losses caused by product liability claims
that could have a material and adverse effect on our business, financial condition, results of operations and prospects.
Our employees, principal investigators,
consultants and commercial partners may engage in misconduct or other improper activities, including noncompliance with regulatory standards
and requirements.
We are exposed to the risk
of fraud, waste, abuse or other misconduct by our employees, principal investigators, consultants and commercial partners. Misconduct
by employees could include intentional failures to comply with FDA regulations, provide accurate information to the FDA, comply with
manufacturing standards we may establish, comply with federal and state healthcare fraud and abuse laws and regulations, report financial
information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in
the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other wasteful
or abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion,
sales commission, customer incentive programs and other business arrangements. Such misconduct could also involve the improper use of
information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation.
It is not always possible to identify and deter misconduct, and the precautions we take to detect and prevent this activity may not be
effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or
lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and
we are not successful in defending ourselves or asserting our rights, those actions could have a material and adverse effect on our business,
financial condition, results of operations and prospects, including the imposition of significant criminal, civil, and administrative
fines or other sanctions, such as monetary penalties, damages, fines, disgorgement, individual imprisonment, exclusion from participation
in government funded healthcare programs, such as Medicare and Medicaid, integrity obligations, reputational harm, and the curtailment
or restructuring of our operations.
20
Our internal computer systems, or those
of CROs or other contractors or consultants we currently use or may use in the future, may fail or suffer security breaches, which could
result in a material disruption of our product development programs.
Our internal computer systems
and those of CROs and other contractors and consultants we use or may use in the future, may be vulnerable to damage from computer viruses,
unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. Such events could cause interruptions
of our operations. For instance, the loss of preclinical data or data from any future clinical trial involving our product candidates
could result in delays in our development and regulatory filing efforts and significantly increase our costs. To the extent that any
disruption or security breach were to result in a loss of, or damage to, our data, or inappropriate disclosure of confidential or proprietary
information, we could incur liability and the development of our product candidates could be delayed.
Our information technology systems could
face serious disruptions that could adversely affect our business.
Our information technology
and other internal infrastructure systems, including corporate firewalls, servers, leased lines and connection to the Internet, face
the risk of systemic failure that could disrupt our operations. A significant disruption in the availability of our information technology
and other internal infrastructure systems could cause interruptions and delays in our research and development work.
If we do not comply with laws regulating
the protection of the environment and health and human safety, our business could be adversely affected.
Our research, development
and manufacturing involve the use of hazardous materials and various chemicals. We maintain quantities of various flammable and toxic
chemicals in our facilities that are required for our research, development and manufacturing activities. We are subject to federal,
state and local laws and regulations governing the use, manufacture, storage, handling and disposal of these hazardous materials. We
believe our procedures for storing, handling and disposing these materials in our facilities comply with the relevant guidelines of the
Commonwealth of Massachusetts and the Occupational Safety and Health Administration of the U.S. Department of Labor. Although we believe
that our safety procedures for handling and disposing of these materials comply with the standards mandated by applicable regulations,
the risk of accidental contamination or injury from these materials cannot be eliminated. If an accident occurs, we could be held liable
for resulting damages, which could be substantial. We are also subject to numerous environmental, health and workplace safety laws and
regulations, including those governing laboratory procedures, exposure to blood-borne pathogens and the handling of animals and biohazardous
materials. Although we maintain workers' compensation insurance to cover us for costs and expenses we may incur due to injuries
to our employees resulting from the use of these materials, this insurance may not provide adequate coverage against potential liabilities.
We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our
storage or disposal of biological or hazardous materials. Additional federal, state and local laws and regulations affecting our operations
may be adopted in the future. We may incur substantial costs to comply with, and substantial fines or penalties if we violate, any of
these laws or regulations.
Our current operations are concentrated
across two locations in close proximity, and we or the third parties upon whom we depend may be adversely affected by natural disasters
and we may not be adequately protected from a serious disaster.
Our current operations are
concentrated across two locations in close proximity outside of Boston, Massachusetts. Any unplanned event, such as flood, fire, explosion,
extreme weather condition, medical epidemics, power shortage, telecommunication failure or other natural or manmade accidents or incidents
that result in us being unable to fully utilize our facilities, or the manufacturing facilities of our third-party contract manufacturers,
may have a material and adverse effect on our ability to operate our business, particularly on a daily basis, and have significant negative
consequences on our financial and operating conditions. Loss of access to these facilities may result in increased costs, delays in the
development of our product candidates or interruption of our business operations. Natural disasters such as snowstorms or hurricanes
could further disrupt our operations, and have a material and adverse effect on our business, financial condition, results of operations
and prospects. If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion
of our headquarters, that damaged critical infrastructure, such as our research facilities or the manufacturing facilities of our third-party
contract manufacturers, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible, for us to continue
our business for a substantial period of time. We do not currently have disaster recovery and business continuity plans in place and
this may have adverse consequences in the event of a serious disaster or similar event. As a result, we may incur substantial expenses,
which could have a material adverse effect on our business. As part of our risk management policy, we maintain insurance coverage at
levels that we believe are appropriate for our business. However, in the event of an accident or incident at these facilities, we cannot
assure you that the amounts of insurance will be sufficient to satisfy any damages and losses. If our facilities, or the manufacturing
facilities of our third-party contract manufacturers, are unable to operate because of an accident or incident or for any other reason,
even for a short period of time, any or all of our research and development programs may be harmed. Any business interruption may have
a material and adverse effect on our business, financial condition, results of operations and prospects.
21
Risks Related to our Intellectual Property
If we are unable to obtain or protect intellectual
property rights related to our technology and current or future product candidates, or if our intellectual property rights are inadequate,
we may not be able to compete effectively.
Our success depends in part
on our ability to obtain and maintain protection with respect to our owned and in-licensed intellectual property and proprietary
technology. We rely on patents and other forms of intellectual property rights, including in-licenses of intellectual property
rights of others, to protect our current or future platforms, product candidates, methods used to manufacture our current or future product
candidates and methods for treating patients using our current or future product candidates.
We cannot predict whether
any future patent applications will result in the issuance of patents that effectively protect any of our product candidates or will
effectively prevent others from commercializing competitive products.
We also rely on our ability
to preserve our trade secrets, to prevent third parties from infringing, misappropriating or violating our proprietary rights and to
operate without infringing, misappropriating or violating the proprietary rights of others. The patent prosecution process is expensive,
complex and time-consuming, and we may not be able to file, prosecute, maintain, enforce or license all necessary or desirable patents
and patent applications at a reasonable cost or in a timely manner.
It is also possible that
we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection.
The patent applications that we own or in-license may fail to result in issued patents, and, even if they do issue as patents,
such patents may not cover our current or future technologies or product candidates in the United States or in other countries or provide
sufficient protection from competitors. In addition, the coverage claimed in a patent application can be significantly reduced before
the patent is issued and its scope can be reinterpreted after issuance. There is no assurance that all of the potentially relevant prior
art relating to our owned or in-licensed patents and patent applications has been found, which can invalidate a patent or prevent
a patent from issuing from a pending application. Even if patents do successfully issue and even if such patents cover our current or
any future technologies or product candidates, third parties may challenge their validity, enforceability or scope, which may result
in such patents being narrowed, invalidated or held unenforceable. Any successful challenge to these patents or any other patents owned
by or licensed to us could deprive us of rights necessary for the successful commercialization of any current or future technologies
or product candidates that we may develop.
If patent applications we
own or have in-licensed with respect to our development programs and current or future technologies or product candidates fail
to issue, if their breadth or strength of protection is threatened, or if they fail to provide meaningful exclusivity, it could dissuade
companies from collaborating with us to develop current or future technologies or product candidates, and threaten our ability to commercialize
current or future products. Any such outcome could have a material adverse effect on our business, financial condition, results of operations
and prospects.
22
The patent positions of biopharmaceutical
companies are generally uncertain because they involve complex legal and factual considerations and have, in recent years, been the subject
of much legislation and litigation. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights
are highly uncertain. The standards applied by the United States Patent and Trademark Office, or USPTO, and foreign patent offices in
granting patents are not always applied uniformly or predictably. For example, there is no uniform worldwide policy regarding patentable
subject matter or the scope of claims allowable in patents. In addition, changes in either the patent laws or interpretation of the patent
laws in the United States and other countries may diminish the value of our owned or in-licensed patents or narrow the scope
of our patent protection. Publications of discoveries in scientific literature often lag behind the actual discoveries and patent applications
in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore,
we cannot know with certainty whether we or our licensors were the first to make the inventions claimed in our owned or in-licensed patents
or pending applications, or that we or our licensors were the first to file for patent protection of such inventions. There is no assurance
that all potentially relevant prior art relating to our owned or in-licensed patents and patent applications has been found.
We may be unaware of prior art that could be used to invalidate an issued patent or prevent our owned or in-licensed pending
patent applications from issuing as patents.
The filing of a patent application
or the issuance of a patent is not conclusive as to its ownership, inventorship, scope, patentability, validity, or enforceability, and
patents and patent applications may be challenged in the courts in the patent office in the Unites States and abroad. For example, we
or our licensors may be subject to a third-party pre-issuance submission of prior art to the USPTO or become involved in opposition,
derivation, reexamination, inter partes review, post-grant review, or interference proceedings, declaratory judgment actions or counterclaims
challenging our owned or in-licensed patent rights or the rights of others. An adverse determination in any such submission,
proceeding, or litigation could prevent the issuance of, reduce the scope of, invalidate, or render unenforceable our owned or in-licensed patent
rights, limit our ability to stop others from using or commercializing similar or identical platforms and products, allow third parties
to compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing
third-party patent rights. In addition, if the breadth or strength of protection provided by our owned or in-licensed patents and
patent applications is threatened, it could dissuade companies from collaborating with us to license, develop, or commercialize current
or future platforms or product candidates. Any of the foregoing could have a material adverse effect on our business, financial condition,
results of operations and prospects.
Any failure to obtain or
any loss of patent protection could have a material adverse impact on our business, financial condition, results of operations and prospects.
We may be unable to prevent competitors from entering the market with a product that is similar to or the same as our current or future
product candidates.
Moreover, some of our owned
and in-licensed patents and patent applications may in the future be co-owned with third parties. If we are unable
to obtain an exclusive license to any such third-party co-owners' interest in such patents or patent application, such co-owners may
be able to license their rights to other third parties, including our competitors, and our competitors could market competing products
and technology. In addition, we may need the cooperation of any such co-owners of our patents in order to enforce such patents
against third parties, and such cooperation may not be provided to us. Any of the foregoing could have a material adverse effect on our
competitive position, business, financial conditions, results of operations, and prospects.
Furthermore, our owned and in-licensed patents
may be subject to a reservation of rights by one or more third parties. For example, we in-license certain patent rights covering
ABP-110 from the National Cancer Institute, or NCI, a division of the National Institutes of Health, or NIH. As a result, the U.S. government
may have certain rights, including so-called march-in rights, to such patent rights and any products or technology developed
from such patent rights. When new technologies are developed with U.S. government funding, the U.S. government generally obtains certain
rights in any resulting patents, including a non-exclusive license authorizing the U.S. government to use the invention for non-commercial purposes.
These rights may permit the U.S. government to disclose our confidential information to third parties and to exercise march-in rights
to use or allow third parties to use our licensed technology. The U.S. government can exercise its march-in rights if it determines
that action is necessary because we fail to achieve the practical application of government-funded technology, because action is necessary
to alleviate health or safety needs, to meet requirements of federal regulations, or to give preference to U.S. industry. In addition,
our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in the United
States. Any exercise by the U.S. government of such rights could harm our competitive position, business, financial condition, results
of operations, and prospects.
23
If we fail to comply with our obligations
under any license, collaboration or other intellectual property related agreements, we may be required to pay damages and could lose
intellectual property rights that are necessary for developing, commercializing and protecting our current or future technologies or
product candidates or we could lose certain rights to grant sublicenses.
We are heavily reliant upon
licenses to certain patent rights and proprietary technology from third parties that are important or necessary to the development of
our technologies and product candidates. Our current license agreements impose, and any future license agreements we enter into are likely
to impose, various development, commercialization, funding, milestone, royalty, diligence, sublicensing, insurance, patent prosecution
and enforcement and/or other obligations on us. We previously were party to an Exclusive License Agreement with Memorial Sloan Kettering
Cancer Center ("MSK"), which was terminated by MSK in September 2023 for our failure to fulfil our payment obligations to
MSK. MSK has demanded payments totaling approximately $1.2 million. We have contacted MSK about possible settlement and have responded
to a counterproposal received from MSK in February 2024, and are continuing discussions. See "
Legal Proceedings
" for
more information. We are in breach of our obligations under our license agreement with MedImmune/AstraZeneca. See " —
Through
our AbMed subsidiary, we have in-licensed certain intellectual property rights relating to ABP-201 from MedImmune
Limited, or MedImmune (now AstraZeneca), and are in breach of the terms of our license agreement with MedImmune/AstraZeneca
."
Our breach of this license agreement or breach of any other license agreement, or the use of intellectual property licensed to us in
an unauthorized manner, may require us to pay damages and the licensor may have the right to terminate the license, which could result
in us being unable to develop, manufacture and sell products that are covered by the licensed technology or enable a competitor to gain
access to the licensed technology. In certain circumstances, our licensed patent rights are subject to our reimbursing our licensors
for their patent prosecution and maintenance costs.
Furthermore, we may not have
the right to control the preparation, filing, prosecution, maintenance, enforcement, and defense of patents and patent applications that
we license from third parties. For example, pursuant to each of our intellectual property licenses with MedImmune, and NCI, our licensors
retain control of preparation, filing, prosecution, and maintenance, and, in certain circumstances, enforcement and defense of the patents
and patent applications. Therefore, we cannot be certain that these patents and patent applications will be prepared, filed, prosecuted,
maintained, enforced, and defended in a manner consistent with the best interests of our business. If our licensors fail to prosecute,
maintain, enforce, and defend such patents, or lose rights to those patents or patent applications, the rights we have licensed may be
reduced or eliminated, and our right to develop and commercialize any of our products or product candidates that are subject of such
licensed rights could be materially adversely affected.
Moreover, our licensors may
own or control intellectual property that has not been licensed to us and, as a result, we may be subject to claims, regardless of their
merit, that we are infringing, misappropriating or otherwise violating the licensor's intellectual property rights. In addition,
while we cannot currently determine the amount of the royalty obligations we would be required to pay on sales of future products, if
any, the amounts may be significant. The amount of our future royalty obligations will depend on the technology and intellectual property
we use in products that we successfully develop and commercialize, if any. Therefore, even if we successfully develop and commercialize
products, we may be unable to achieve or maintain profitability.
In addition, the agreements
under which we currently license intellectual property or technology from third parties are complex, and certain provisions in such agreements
may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow
what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be
our financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business,
financial condition, results of operations, and prospects. Moreover, if disputes over intellectual property that we have licensed prevent
or impair our ability to maintain our current licensing arrangements on commercially acceptable terms, we may be unable to successfully
develop and commercialize the affected product candidates, which could have a material adverse effect on our business, financial conditions,
results of operations, and prospects.
24
Patent terms may be inadequate to protect
our competitive position on our current or future technologies or product candidates for an adequate amount of time.
Patents have a limited lifespan.
In the United States, the standard expiration of a patent is generally 20 years after it is filed. Various extensions may be available.
However, the life of a patent and the protection it affords is limited. As a result, our owned and in-licensed patent portfolio
may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours. For example,
given the large amount of time required for the research, development, testing and regulatory review of new product candidates, patents
protecting such candidates might expire before or shortly after such candidates are commercialized. In the United States, the Drug Price
Competition and Patent Term Restoration Act of 1984 permits a patent term extension of up to five years beyond the normal expiration
of the patent, which is limited to the approved indication (or any additional indications approved during the period of extension). Additionally,
a patent term extension cannot extend the remaining term of a patent beyond 14 years from the date of product approval, only one patent
may be extended and only those claims covering the approved drug, a method for using it, or a method for manufacturing it may be extended.
However, the applicable authorities, including the FDA and the USPTO in the United States, and any equivalent regulatory authority in
other countries, may not agree with our assessment of whether such extensions are available, and may refuse to grant extensions to our
patents, or may grant more limited extensions than we request. An extension may not be granted or may be limited because of, for example
a failure to exercise due diligence during the testing phase or regulatory review process, failing to apply within applicable deadlines,
failing to apply prior to expiration of relevant patents, or otherwise failing to satisfy applicable requirements. If this occurs, our
competitors may be able to take advantage of our investment in development and clinical trials by referencing our clinical and preclinical
data and launch their product earlier than might otherwise be the case, which could have a material adverse effect on our business, financial
condition, results of operations and prospects.
Changes in U.S. patent law or the patent
law of other countries or jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our
current or any future technologies or product candidates.
Changes in either the patent
laws or interpretation of the patent laws in the United States could increase the uncertainties and costs surrounding the prosecution
of patent applications and the enforcement or defense of issued patents. The United States has recently enacted and implemented wide-ranging
patent reform legislation. On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law,
which could increase the uncertainties and costs surrounding the prosecution of our owned or in-licensed patent applications
and the enforcement or defense of our owned or in-licensed issued patents. The Leahy-Smith Act includes a number of significant
changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted, redefine prior art, may
affect patent litigation and switch the U.S. patent system from a "first-to-invent" system to a "first-to-file" system.
Under a first-to-file system, assuming the other requirements for patentability are met, the first inventor to file a patent
application generally will be entitled to the patent on an invention regardless of whether another inventor had made the invention earlier.
These provisions also allow third-party submission of prior art to the USPTO during patent prosecution and set forth additional procedures
to challenge the validity of a patent by the USPTO administered post grant proceedings, including derivation, reexamination, inter partes
review, post-grant review, and interference proceedings. The USPTO developed additional regulations and procedures to govern administration
of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and, in particular, the first-to-file provisions,
only became effective on March 16, 2013. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the
operation of our business. The Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution
of our owned or in-licensed patent applications and the enforcement or defense of our issued owned or in-licensed patents,
all of which could have a material adverse effect on our business, financial condition, results of operations and prospects.
The U.S. Supreme Court has
ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or
weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our and our licensors'
ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once
obtained. The recent decision by the Supreme Court in Association for Molecular Pathology v. Myriad Genetics, Inc. precludes claims directed
to a nucleic acid having a stated nucleotide sequence that is identical to a sequence found in nature and that is unmodified. This decision
has yet to be clearly interpreted by other courts and by the USPTO. We cannot assure you that the interpretations of this decision or
that subsequent rulings will not adversely impact our owned or in-licensed patents or patent applications. Depending on decisions
by the U.S. Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways
that would weaken our and our licensors' ability to obtain new patents or to enforce our existing owned or in-licensed patents
and patents that we might obtain or in-license in the future. Similarly, changes in patent law and regulations in other countries
or jurisdictions or changes in the governmental bodies that enforce them or changes in how the relevant governmental authority enforces
patent laws or regulations may have a material adverse effect on our and our licensors' ability to obtain new patents or to protect
and enforce our owned or in-licensed patents or that we may obtain or in-license in the future.
25
Other companies or organizations may challenge
our or our licensors' patent rights or may assert patent rights that prevent us from developing and commercializing our current
or future products.
Bispecific antibodies are
a relatively new scientific field. As the field of antibody and immunoregulatory therapeutics matures, patent applications are being
processed by national patent offices around the world. There is uncertainty about which patents will issue, and, if they do, as to when,
to whom, and with what claims. In addition, third parties may attempt to invalidate our or our licensors' intellectual property
rights. Even if such rights are not directly challenged, disputes could lead to the weakening of our or our licensors' intellectual
property rights. Our defense against any attempt by third parties to circumvent or invalidate our intellectual property rights could
be costly to us, could require significant time and attention of our management and could have a material and adverse effect on our business,
financial condition, results of operations and prospects or our ability to successfully compete.
There are many issued and
pending patents that claim aspects of our current or future product candidates and modifications that we may need to apply to our current
or future product candidates. There are also many issued patents that claim antibodies or portions of antibodies that may be relevant
for products we wish to develop. Thus, it is possible that one or more third parties will hold patent rights to which we will need a
license, which may not be available on reasonable terms or at all. If those third parties refuse to grant us a license to such patent
rights on reasonable terms or at all, we may be required to expend significant time and resources to redesign our technology, product
candidates, or the methods for manufacturing them or to develop or license replacement technology, all of which may not be feasible on
a technical or commercial basis. If we are unable to do so, we may not be able to market such technology or product candidates or perform
research and development or other activities covered by these patents, which could have a material adverse effect on our business, financial
condition, results of operations and prospects.
We may not be able to protect our intellectual
property rights throughout the world, which could negatively impact our business.
Filing, prosecuting and defending
patents on current or future technologies or product candidates in all countries throughout the world would be prohibitively expensive.
Competitors or other third parties may use our technologies in jurisdictions where we have not obtained patent protection to develop
their own products and, further, may export otherwise infringing products to territories where we have patent protection or licenses
but enforcement is not as strong as that in the United States. These products may compete with our products, and our patents or other
intellectual property rights may not be effective or sufficient to prevent them from competing.
Additionally, the laws of
some foreign jurisdictions do not protect intellectual property rights to the same extent as the laws in the United States, and many
companies have encountered significant difficulties in protecting and defending such rights in such jurisdictions. The legal systems
of certain countries, including certain developing countries, do not favor the enforcement of patents and other intellectual property
protection, particularly those relating to biotechnology, which could make it difficult for us to stop the infringement of our owned
and in-licensed patents or the marketing of competing products in violation of our intellectual property and proprietary rights
generally. Proceedings to enforce our owned or in-licensed intellectual property and proprietary rights in foreign jurisdictions
could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our owned or in-licensed patents
at risk of being invalidated or interpreted narrowly, could put our owned or in-licensed patent applications at risk of not
issuing, and could provoke third parties to assert claims against us or our licensors. We or our licensors may not prevail in any lawsuits
that we or our licensors initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly,
our and our licensors' efforts to enforce such intellectual property and proprietary rights around the world may be inadequate
to obtain a significant commercial advantage from the intellectual property that we develop or in-license.
Many countries have compulsory
licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the
enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited
remedies, which could materially diminish the value of its patents. If we or any of our licensors are forced to grant a license to third
parties with respect to any patents relevant to our business, our competitive position in the relevant jurisdiction may be impaired and
our business, financial condition, results of operations and prospects may be materially adversely affected.
26
Third parties may initiate legal proceedings
alleging that we are infringing, misappropriating or violating their intellectual property rights, the outcome of which would be uncertain
and could have a material adverse impact on the success of our business.
Our commercial success depends,
in part, upon our ability and the ability of our current or future collaborators to develop, manufacture, market and sell our current
or any future product candidates and use our proprietary technologies without infringing, misappropriating or violating the proprietary
and intellectual property rights of third parties. The biotechnology and pharmaceutical industries are characterized by extensive and
complex litigation regarding patents and other intellectual property rights.
We or our licensors, or any
future strategic partners may be party to, or be threatened with, adversarial proceedings or litigation regarding intellectual property
rights with respect to our current or any future product candidates and technologies, including derivation, reexamination, inter partes
review, post-grant review, or interference proceedings before the USPTO and similar proceedings in jurisdictions outside of the United
States such as opposition proceedings. In some instances, we may be required to indemnify our licensors for the costs associated with
any such adversarial proceedings or litigation. For example, our majority-owned subsidiary, AbMed Corporation, is obligated under the
Collaboration and License Agreement with MedImmune to indemnify and hold harmless MedImmune for damages arising from intellectual property
infringement by us resulting from exercise of the license from MedImmune. Third parties may assert infringement claims against us, our
licensors or our strategic partners based on existing patents or patents that may be granted in the future, regardless of their merit.
There is a risk that third parties may choose to engage in litigation with us, our licensors or our strategic partners to enforce or
to otherwise assert their patent rights. Even if we believe such claims are without merit, a court of competent jurisdiction could hold
that these third-party patents are valid, enforceable and infringed, which could have a material adverse impact on our ability to commercialize
our current or any future platforms or product candidates. In order to successfully challenge the validity of any such U.S. patent in
federal court, we would need to overcome a presumption of validity. As this burden is a high one requiring us to present clear and convincing
evidence as to the invalidity of any such U.S. patent claim, there is no assurance that a court of competent jurisdiction would invalidate
the claims of any such U.S. patent.
If we or our licensors, or
any future strategic partners are found to infringe, misappropriate or violate a third-party patent or other intellectual property rights,
we could be required to pay damages, including treble damages and attorney's fees, if we are found to have willfully infringed.
In addition, we or our licensors, or any future strategic partners may choose to seek, or be required to seek, a license from a third
party, which may not be available on commercially reasonable terms, if at all. Even if a license can be obtained on commercially reasonable
terms, the rights may be non-exclusive, which could give our competitors access to the same technology or intellectual property
rights licensed to us, and it could require us to make substantial licensing and royalty payments. We also could be forced, including
by court order, to cease developing, manufacturing and commercializing the infringing platforms or product candidates. Any of the foregoing
could have a material adverse effect on our ability to generate revenue or achieve profitability and possibly prevent us from generating
revenue sufficient to sustain our operations.
In addition, we or our licensors
may find it necessary to pursue claims or initiate lawsuits to protect or enforce our owned or in-licensed patent or other
intellectual property rights. The cost to us in defending or initiating any litigation or other proceeding relating to our owned or in-licensed patent
or other intellectual property rights, even if resolved in our favor, could be substantial, and any litigation or other proceeding would
divert our management's attention. Such litigation or proceedings could materially increase our operating losses and reduce the
resources available for development activities or any future sales, marketing or distribution activities. Some of our competitors may
be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources.
Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could delay our research and development
efforts and materially limit our ability to continue our operations. Furthermore, because of the substantial amount of discovery required
in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by
disclosure during this type of litigation. In addition, there could be public announcements of the results of hearings, motions or other
interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a material
adverse effect on the price of our common stock.
27
If we or our licensors were
to initiate legal proceedings against a third party to enforce a patent covering one of our product candidates or our technology, the
defendant could counterclaim that such patent is invalid or unenforceable. In patent litigation in the United States, defendant counterclaims
alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of
several statutory requirements, for example, lack of novelty, indefiniteness, lack of written description, obviousness or non-enablement. Grounds
for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information
from the USPTO, or made a misleading statement, during prosecution. The outcome following legal assertions of invalidity and unenforceability
during patent litigation is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no
invalidating prior art, of which we or our licensors and the patent examiner were unaware during prosecution. If a defendant were to
prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection
on one or more of our product candidates or certain aspects of our platform technology. Such a loss of patent protection could have a
material adverse effect on our business, financial condition, results of operations and prospects. Patents and other intellectual property
rights also will not protect our product candidates and technologies if competitors or third parties design around such product candidates
and technologies without legally infringing, misappropriating or violating our owned or in-licensed patents or other intellectual
property rights.
Intellectual property rights of third parties
could adversely affect our ability to commercialize our current or future technologies or product candidates, and we might be required
to litigate or obtain licenses from third parties in order to develop or market our current or future technologies or product candidates,
which may not be available on commercially reasonable terms or at all.
Because the antibody landscape
is still evolving, it is difficult to conclusively assess our freedom to operate without infringing, misappropriating or violating third-party
rights. There are numerous companies that have pending patent applications and issued patents broadly covering antibodies generally or
covering antibodies directed against the same targets as, or targets similar to, those we are pursuing. Our competitive position may
materially suffer if patents issued to third parties or other third-party intellectual property rights cover our current or future technologies
or product candidates or elements thereof, or our manufacture or uses relevant to our development plans. In such cases, we may not be
in a position to develop or commercialize current or future technologies or product candidates unless we successfully pursue litigation
to nullify or invalidate the third-party intellectual property right concerned, or enter into a license agreement with the intellectual
property right holder, if available on commercially reasonable terms. There may be issued patents of which we are not aware, held by
third parties that, if found to be valid and enforceable, could be alleged to be infringed by our current or future technologies or product
candidates. There also may be pending patent applications of which we are not aware that may result in issued patents, which could be
alleged to be infringed by our current or future technologies or product candidates. If such an infringement claim should be brought
and be successful, we may be required to pay substantial damages, be forced to abandon our current or future technologies or product
candidates or seek a license from any patent holders. No assurances can be given that a license will be available on commercially reasonable
terms, if at all.
It is also possible that
we have failed to identify relevant third-party patents or applications. For example, U.S. applications filed before November 29,
2000 and certain U.S. applications filed after that date that will not be filed outside the U.S. remain confidential until patents issue.
Patent applications in the United States and elsewhere are published approximately 18 months after the earliest filing for which priority
is claimed, with such earliest filing date being commonly referred to as the priority date. Therefore, patent applications covering our
product candidates or platform technologies could have been filed by others without our knowledge. Additionally, pending patent applications
that have been published can, subject to certain limitations, be later amended in a manner that could cover our platforms, our product
candidates or the use of our technologies. Third-party intellectual property right holders may also actively bring infringement, misappropriation
or violation claims against us. We cannot guarantee that we will be able to successfully settle or otherwise resolve such claims. If
we are unable to successfully settle future claims on terms acceptable to us, we may be required to engage in or continue costly, unpredictable
and time-consuming litigation and may be prevented from or experience substantial delays in marketing our product candidates. If we fail
in any such dispute, in addition to being forced to pay damages, we may be temporarily or permanently prohibited from commercializing
any of our current or future technologies or product candidates that are held to be infringing, misappropriating or violating. We might,
if possible, also be forced to redesign current or future technologies or product candidates so that we no longer infringe, misappropriate
or violate the third-party intellectual property rights. Any of these events, even if we were ultimately to prevail, could require us
to divert substantial financial and management resources that we would otherwise be able to devote to our business, which could have
a material adverse effect on our business, financial condition, results of operations and prospects.
28
If we are unable to protect the confidentiality
of our trade secrets, our business and competitive position would be harmed.
In addition to seeking patent
protection for certain aspects of our current or future technologies and product candidates, we also consider trade secrets, including
confidential and unpatented know-how, important to the maintenance of our competitive position. However, trade secrets and know-how can
be difficult to protect. We protect trade secrets and confidential and unpatented know-how, in part, by entering into non-disclosure and
confidentiality agreements with parties who have access to such knowledge, such as our employees, corporate collaborators, outside scientific
collaborators, CROs, contract manufacturers, consultants, advisors and other third parties. We also enter into confidentiality and invention
or patent assignment agreements with our employees and consultants that obligate them to maintain confidentiality and assign their inventions
to us. Despite these efforts, any of these parties may breach such agreements and disclose our proprietary information, including our
trade secrets, and we may not be able to obtain adequate remedies for such breaches. We may also become involved in inventorship disputes
relating to inventions and patents developed by our employees or consultants under such agreements. Enforcing a claim that a party illegally
disclosed or misappropriated a trade secret, or securing title to an employee-or consultant-developed invention if a dispute arises,
is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts in the United States and certain
foreign jurisdictions are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained
or independently developed by a competitor, we would have no right to prevent them from using that technology or information to compete
with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would
be materially and adversely harmed.
We may be subject to claims that we or
our employees or consultants have wrongfully used or disclosed alleged trade secrets or other proprietary information of our employees'
or consultants' former employers or their clients.
Many of our employees were
previously employed at universities or biotechnology or biopharmaceutical companies, including our competitors or potential competitors.
We may be subject to claims that these employees or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary
information of their former employers. Litigation may be necessary to defend against these claims. If we fail in defending such claims,
in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel or may be enjoined from using
such intellectual property, and would likely divert significant resources from our core business, including distracting our technical
and management personnel from their normal responsibilities. A loss of key research personnel or their work product could limit our ability
to commercialize, or prevent us from commercializing, our current or future technologies or product candidates, which could materially
harm our business. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a
distraction to management.
Obtaining and maintaining our patent protection
depends on compliance with various procedural, document submission, fee payment and other requirements imposed by government patent agencies,
and our patent protection could be reduced or eliminated for non-compliance with these requirements.
Periodic maintenance fees,
renewal fees, annuity fees and various other government fees on patents and/or applications will be due to be paid to the USPTO and various
government patent agencies outside of the United States over the lifetime of our owned and in-licensed patents and/or applications
and any patent rights we may own or in-license in the future. The USPTO and various non-U.S. government patent agencies
require compliance with several procedural, documentary, fee payment and other similar provisions during the patent application process.
We employ reputable law firms and other professionals to help us comply, and we are also dependent on our licensors to take the necessary
action to comply with these requirements with respect to our in-licensed intellectual property. In many cases, an inadvertent
lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules. There are situations, however,
in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete
loss of patent rights in the relevant jurisdiction. In such an event, potential competitors might be able to enter the market with similar
or identical products or platforms, which could have a material adverse effect on our business, financial condition, results of operations
and prospects.
29
If our trademarks and trade names are not
adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely
affected.
Our trademarks or trade names
may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. We may not be able to protect
our rights to these trademarks and trade names or may be forced to stop using these names, which we need for name recognition by potential
partners or customers in our markets of interest. If we are unable to establish name recognition based on our trademarks and trade names,
we may not be able to compete effectively and our business may be materially adversely affected.
Intellectual property rights do not necessarily
address all potential threats to our business.
The degree of future protection
afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not adequately
protect our business. The following examples are illustrative:
●
others
may be able to make compounds or formulations that are similar to our product candidates, but that are not covered by the claims of any
patents, should they issue, that we own, license or control;
●
we
or any strategic partners might not have been the first to make the inventions covered by the issued patents or pending patent applications
that we own, license or control;
●
we
or our licensors might not have been the first to file patent applications covering certain of our owned and in-licensed inventions;
●
others
may independently develop similar or alternative technologies or duplicate any of our technologies without infringing, misappropriating
or violating our owned or in-licensed intellectual property rights;
●
it
is possible that our owned or in-licensed pending patent applications will not lead to issued patents;
●
issued
patents that we own, in-license or control may not provide us with any competitive advantages, or may be narrowed or held invalid
or unenforceable, including as a result of legal challenges;
●
our
competitors might conduct research and development activities in the United States and other countries that provide a safe harbor from
patent infringement claims for certain research and development activities, as well as in countries where we do not have patent rights
and then use the information learned from such activities to develop competitive products for sale in our major commercial markets;
●
we
may not develop additional proprietary platforms that are patentable;
●
we
may choose not to file a patent in order to maintain certain trade secrets or know-how, and a third party may subsequently
file a patent covering such trade secrets or know-how; and
●
the
patents of others may have an adverse effect on our business.
Should any of these events
occur, they could have a material adverse effect on our business, financial condition, results of operations and prospects.

Risks Related to Government Regulation
Clinical development involves a lengthy and expensive process
with an uncertain outcome, and results of earlier studies and trials may not be predictive of future trial results.
All of our product candidates
are in preclinical development and their risk of failure is high. It is impossible to predict when or if any of our product candidates
will prove effective and safe in humans or will receive regulatory approval. Before obtaining marketing approval from regulatory authorities
for the sale of any product candidate, we must complete preclinical studies and then conduct extensive clinical trials to demonstrate
the safety and efficacy of our product candidates in humans. Clinical testing is expensive and can take many years to complete, and its
outcome is inherently uncertain. Failure can occur at any time during the development process. The results of preclinical studies and
early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials. Product candidates
in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical
studies and initial clinical trials. A number of companies in the pharmaceutical industry have suffered significant setbacks in advanced
clinical trials due to lack of efficacy or safety profiles, notwithstanding promising results in earlier trials.
We expect to commence clinical
trials of our two lead product candidates, ABP-102 for the treatment of breast and gastric cancers, and ABP-201 for
the treatment of wet age-related macular degeneration (Wet AMD) and diabetic macular edema (DME) in 2026. Commencing these
clinical trials is subject to finalizing the trial design and filing an IND or similar filing with the FDA or similar foreign regulatory
authority. Even after we file our IND or comparable submissions in other jurisdictions, the FDA or other regulatory authorities could
disagree that we have satisfied their requirements to commence our clinical trials or disagree with our study design, which may require
us to complete additional preclinical studies or amend our protocols or impose stricter conditions on the commencement of clinical trials.
We may experience delays
in completing our preclinical studies and initiating or completing clinical trials of our product candidates. We do not know whether
planned preclinical studies and clinical trials will be completed on schedule or at all, or whether planned clinical trials will begin
on time, need to be redesigned, enroll patients on time or be completed on schedule, if at all. Our development programs may be delayed
for a variety of reasons, including delays related to:
●
the
FDA or other regulatory authorities requiring us to submit additional data or imposing other requirements before permitting us to initiate
a clinical trial;
●
obtaining
regulatory approval to commence a clinical trial;
●
reaching
agreement on acceptable terms with prospective CROs and clinical trial sites, the terms of which can be subject to extensive negotiation
and may vary significantly among different CROs and clinical trial sites;
●
obtaining
institutional review board, or IRB, approval at each clinical trial site;
●
recruiting
suitable patients to participate in a clinical trial;
●
having
patients complete a clinical trial or return for post-treatment follow-up;
●
clinical
trial sites deviating from trial protocol or dropping out of a trial;
●
adding
new clinical trial sites; or
●
manufacturing
sufficient quantities of our product candidates for use in clinical trials.
Patient enrollment, a significant
factor in the timing of clinical trials, is affected by many factors including the size and nature of the patient population, the proximity
of patients to clinical sites, the eligibility criteria for the trial, the design of the clinical trial, the severity of the disease
under investigation, our payments for conducting clinical trials, competing clinical trials and clinicians' and patients'
perceptions as to the potential advantages of the product candidate being studied in relation to other available therapies, including
any new drugs or therapeutic biologics that may be approved for the indications we are investigating. Especially because our product
candidates may initially target indications that may be characterized as orphan markets, the clinical trial timeline for the regulatory
process could be prolonged if sufficient patients cannot be enrolled in a timely manner. Furthermore, we expect to rely on our partners,
CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials and while we expect to enter into agreements
governing their committed activities, we have limited influence over their actual performance.
31
We could encounter delays
if prescribing physicians encounter unresolved ethical issues associated with enrolling patients in clinical trials of our product candidates
in lieu of prescribing existing treatments that have established safety and efficacy profiles. Further, a clinical trial may be suspended
or terminated by us, our partners, the IRBs of the institutions in which such trials are being conducted, the Data Safety Monitoring
Board for such trial or by the FDA or other regulatory authorities due to a number of factors, including failure to conduct the clinical
trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site
by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects,
failure to demonstrate a benefit from using a drug or therapeutic biologic, changes in governmental regulations or administrative actions
or lack of adequate funding to continue the clinical trial. If we experience delays in the completion of, or termination of, any clinical
trial of our product candidates, the commercial prospects of our product candidates will be harmed, and our ability to generate product
revenues from any of these product candidates will be delayed. In addition, any delays in completing our clinical trials will increase
our costs, slow down our product development and approval process and jeopardize our ability to commence product sales and generate revenues.
Any of these occurrences may materially and adversely affect our business, financial condition, results of operations and prospects.
In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately
lead to the denial of regulatory approval of our product candidates.
We may be unable to obtain U.S. or foreign regulatory approval
and, as a result, be unable to commercialize our product candidates, resulting in substantial harm to our business.
We cannot commercialize a
product until the appropriate regulatory authorities have reviewed and approved the product candidate. Our product candidates are subject
to extensive governmental regulations relating to, among other things, research, testing, development, manufacturing, safety, efficacy,
approval, recordkeeping, reporting, labeling, storage, packaging, advertising and promotion, pricing, marketing and distribution of drugs
and therapeutic biologics. Rigorous preclinical testing and clinical trials and an extensive regulatory approval process are required
to be successfully completed in the U.S. and in many foreign jurisdictions before a new drug or therapeutic biologic can be marketed.
Satisfaction of these and other regulatory requirements is costly, time consuming, uncertain and subject to unanticipated delays. It
is possible that none of the product candidates we may develop will obtain the regulatory approvals necessary for us or our existing
or future partners to begin selling them. We have very limited experience in conducting and managing the clinical trials necessary to
obtain regulatory approvals, including approval by the FDA. The time required to obtain FDA and other approvals is unpredictable but
typically takes many years following the commencement of clinical trials, depending upon the type, complexity and novelty of the product
candidate. The standards that the FDA and its foreign counterparts use when regulating us require judgment and can change, which makes
it difficult to predict with certainty how they will be applied. Any analysis we perform of data from preclinical and clinical activities
is subject to confirmation and interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. We
may also encounter unexpected delays or increased costs due to new government regulations, for example, from future legislation or administrative
action, or from changes in FDA policy during the period of product development, clinical trials and FDA regulatory review. It is impossible
to predict whether legislative changes will be enacted, or whether FDA or foreign regulations, guidance or interpretations will be changed,
or what the impact of such changes, if any, may be.
We believe the FDA has limited
early experience with bispecific antibody-based therapeutics, which may increase the complexity, uncertainty and length of the regulatory
approval process for our product candidates. For example, the FDA may require us to provide additional data to support our regulatory
applications, including Biologics License Applications ("BLAs"). In addition, because there may be approved treatments for
some of the diseases for which we may seek approval, in order to receive regulatory approval, we may need to demonstrate through clinical
trials that the product candidates we develop to treat these diseases, if any, are not only safe and effective, but safer or more effective
than existing products.
Any delay or failure in obtaining
required approvals could have a material and adverse effect on our ability to generate revenues from the particular product candidate
for which we are seeking approval. Furthermore, any regulatory approval to market a product may be subject to limitations on the approved
uses for which we may market the product or the labeling or other restrictions.
32
We are also subject to numerous
foreign regulatory requirements governing, among other things, the conduct of clinical trials, manufacturing and marketing authorization,
pricing and third-party reimbursement. The foreign regulatory approval process varies among countries and may include all of the risks
associated with FDA approval described above as well as risks attributable to the satisfaction of local regulations in foreign jurisdictions.
Moreover, the time required to obtain approval may differ from that required to obtain FDA approval. Approval by the FDA does not ensure
approval by regulatory authorities outside the United States and vice versa.
We may in the future conduct clinical trials
for current or future product candidates outside the United States, and the FDA and comparable foreign regulatory authorities may not
accept data from such trials.
We may in the future choose
to conduct one or more clinical trials outside the United States. The acceptance of study data from clinical trials conducted outside
the United States or another jurisdiction by the FDA or comparable foreign regulatory authority may be subject to certain conditions
or may not be accepted at all. In cases where data from foreign clinical trials are intended to serve as the sole basis for marketing
approval in the United States, the FDA will generally not approve the application on the basis of foreign data alone unless (i) the
data are applicable to the U.S. population and U.S. medical practice; (ii) the trials were performed by clinical investigators of
recognized competence and pursuant to GCP regulations; and (iii) the data may be considered valid without the need for an on-site inspection
by the FDA, or if the FDA considers such inspection to be necessary, the FDA is able to validate the data through an on-site inspection
or other appropriate means. In addition, even where the foreign study data are not intended to serve as the sole basis for approval,
the FDA will not accept the data as support for an application for marketing approval unless the study is well-designed and well-conducted
in accordance with GCP and the FDA is able to validate the data from the study through an onsite inspection, if deemed necessary. Many
foreign regulatory authorities have similar approval requirements. In addition, such foreign trials would be subject to the applicable
local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any comparable foreign
regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or
any comparable foreign regulatory authority does not accept such data, it would result in the need for additional trials, which could
be costly and time-consuming, and which may result in current or future product candidates that we may develop not receiving approval
for commercialization in the applicable jurisdiction.
Further, conducting clinical
trials in foreign countries, as we may do for our product candidates, presents additional risks that may delay completion of our clinical
trials. These risks include the failure of enrolled patients in foreign countries to adhere to clinical protocol as a result of differences
in healthcare services or cultural customs, managing additional administrative burdens associated with foreign regulatory schemes, as
well as political and economic risks relevant to such foreign countries.
Even if we receive regulatory approval
for any of our product candidates, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result
in significant additional expense. Additionally, our product candidates, if approved, could be subject to labeling and other restrictions
and market withdrawal and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated
problems with our products.
Any regulatory approvals
that we or our existing or future partners obtain for our product candidates may also be subject to limitations on the approved indicated
uses for which a product may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing
testing, including "Phase 4" clinical trials, and surveillance to monitor the safety and efficacy of the product candidate.
In addition, if the FDA or a comparable foreign regulatory authority approves any of our product candidates, the manufacturing processes,
labeling, packaging, distribution, adverse event reporting, storage, import, export, advertising, promotion and recordkeeping for the
product will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other
post-marketing information and reports, registration, as well as continued compliance with cGMPs and GCPs for any clinical trials that
we conduct post-approval. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity
or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may
result in, among other things:
●
restrictions
on the marketing or manufacturing of the product, withdrawal of the product from the market or voluntary or mandatory product recalls;
●
fines,
warning letters or holds on clinical trials;
33
●
refusal
by the FDA to approve pending applications or supplements to approved applications filed by us or our strategic partners;
●
suspension
or revocation of product license approvals;
●
product
seizure or detention or refusal to permit the import or export of products; and;
●
injunctions
or the imposition of civil or criminal penalties.
The FDA's policies
may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product
candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative
action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption
of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we
may have obtained and we may not achieve or sustain profitability, which would adversely affect our business.
We may fail to obtain and maintain orphan drug designation from
the FDA for our current and future product candidates, as applicable.
Our strategy may include
filing for orphan drug designation if and where available for our product candidates. Under the Orphan Drug Act, the FDA may grant orphan
drug designation to a drug or biologic intended to treat a rare disease or condition, which is defined as one occurring in a patient
population of fewer than 200,000 in the United States, or a patient population greater than 200,000 in the United States where there
is no reasonable expectation that the cost of developing the drug or biologic will be recovered from sales in the United States. In the
United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical
trial costs, tax advantages and user-fee exemptions. In addition, if a product that has orphan drug designation subsequently
receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan drug exclusivity,
which means that the FDA may not approve any other applications, including a full NDA or BLA, to market the same drug or biologic for
the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan
drug exclusivity or where the original manufacturer is unable to assure sufficient product quantity.
We may pursue orphan designations
for our lead product candidates ABP-102 and ABP-201. However, while we may seek orphan drug designations for our
product candidates, we may never receive such designations. In addition, orphan drug designation neither shortens the development time
or regulatory review time of a drug, nor gives the drug any advantage in the regulatory review or approval process. Even if we obtain
such designations, we may not be the first to obtain regulatory approval of a product candidate for the orphan-designated indication
due to the uncertainties associated with developing pharmaceutical products. We may also fail to meet requirements to maintain orphan
drug designation while developing ABP-102 and ABP-201. In addition, exclusive marketing rights in the United States
may be limited if we decide to seek approval for an indication broader than the orphan-designated indication or may be lost if the FDA
later determines that the request for designation was materially defective or if we are unable to assure sufficient quantities of the
product to meet the needs of patients with the orphan-designated disease or condition. Further, even if we obtain orphan drug exclusivity
for a product, that exclusivity may not effectively protect the product from competition because different drugs with different active
moieties may receive and be approved for the same condition, and only the first applicant to receive approval will receive the benefits
of marketing exclusivity. Even after an orphan-designated product is approved, the FDA can subsequently approve a later drug with the
same active moiety for the same condition if the FDA concludes that the later drug is clinically superior if it is shown to be safer,
more effective or makes a major contribution to patient care.
34
We may attempt to secure approval from the FDA through the use
of accelerated approval pathways. If unable to obtain approval under an accelerated pathway, we may be required to conduct additional
preclinical studies or clinical trials which could increase the expense of obtaining, reduce the likelihood of obtaining and/or delay
the timing of obtaining, necessary marketing approvals. Even if we receive accelerated approval from the FDA, if our confirmatory trials
do not verify clinical benefit, or if we do not comply with rigorous post-marketing requirements, the FDA may seek to withdraw accelerated
approval.
We may seek an accelerated
approval development pathway for our product candidates, including ABP-102 and ABP-201. Under the accelerated approval
provisions of the Federal Food, Drug, and Cosmetic Act (the "FDCA"), and the FDA's implementing regulations, the FDA
may grant accelerated approval to a product designed to treat a serious or life-threatening condition that provides meaningful therapeutic
advantage over available therapies and demonstrates an effect on a surrogate endpoint or intermediate clinical endpoint that is reasonably
likely to predict clinical benefit. The FDA considers a clinical benefit to be a positive therapeutic effect that is clinically meaningful
in the context of a given disease. For the purposes of accelerated approval, a surrogate endpoint is a marker, such as a laboratory measurement,
radiographic image, physical sign, or other measure that is thought to predict clinical benefit, but is not itself a measure of clinical
benefit. An intermediate clinical endpoint is a clinical endpoint that can be measured earlier than an effect on irreversible morbidity
or mortality that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit. The accelerated
approval development pathway may be used in cases in which the advantage of a new drug over available therapy may not be a direct therapeutic
advantage, but is a clinically important improvement from a patient and public health perspective. If granted, accelerated approval is
contingent on the sponsor's agreement to conduct, in a diligent manner, additional post-approval confirmatory studies to verify
and describe the drug's clinical profile or risks and benefits for accelerated approval. The FDA may require that any such confirmatory
study be initiated or substantially underway prior to the submission of an application for accelerated approval. If such post-approval
studies fail to confirm the drug's clinical profile or risks and benefits, the FDA may withdraw its approval of the drug.
If we choose to pursue accelerated
approval, we intend to seek feedback from the FDA or will otherwise evaluate our ability to seek and receive such accelerated approval.
There can be no assurance that, after our evaluation of the feedback from the FDA or other factors, we will decide to pursue or submit
a BLA for accelerated approval or any other form of expedited development, review or approval. Furthermore, if we submit an application
for accelerated approval, there can be no assurance that such application will be accepted or that approval will be granted on a timely
basis, or at all. The FDA also could require us to conduct further studies or trials prior to considering our application or granting
approval of any type. We might not be able to fulfill the FDA's requirements in a timely manner, which would cause delays, or approval
might not be granted because our submission is deemed incomplete by the FDA. A failure to obtain accelerated approval or any other form
of expedited development, review or approval for a product candidate would result in a longer time period to commercialize such product
candidate, could increase the cost of development of such product candidate and could harm our competitive position in the marketplace.
Even if we receive accelerated
approval from the FDA, we will be subject to rigorous post-marketing requirements, including the completion of confirmatory post-market
clinical trial(s) to verify the clinical benefit of the product, and submission to the FDA of all promotional materials prior to their
dissemination. The FDA could seek to withdraw accelerated approval for multiple reasons, including if we fail to conduct any required
post-market study with due diligence, a post-market study does not confirm the predicted clinical benefit, other evidence shows that
the product is not safe or effective under the conditions of use, or we disseminate promotional materials that are found by the FDA to
be false and misleading.
Healthcare legislative reform measures may have a material adverse
effect on our business and results of operations.
In the United States, there
have been a number of legislative and regulatory changes to the health care system that could impact our ability to sell our products
profitably. In particular, in 2010, the Patient Protection and Affordable Care Act, or the ACA, was enacted, which, among other things,
addressed a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that
are inhaled, infused, instilled, implanted or injected; increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid
Drug Rebate Program; extended the Medicaid Drug Rebate program to utilization of prescriptions of individuals enrolled in Medicaid managed
care organizations; subjected manufacturers to new annual fees and taxes for certain branded prescription drugs; created a new Medicare
Part D coverage gap discount program, in which manufacturers must agree to offer 50% (increased to 70% pursuant to the Bipartisan Budget
Act of 2018, effective as of January 1, 2019) point-of-sale discounts off negotiated prices of applicable brand drugs
to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer's outpatient drugs to be covered
under Medicare Part D; and provided incentives to programs that increase the federal government's comparative effectiveness research.
35
Since its enactment, there
have been judicial, Congressional and executive challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court
dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality
of the ACA. Prior to the Supreme Court's decision, President Biden issued an executive order to initiate a special enrollment period
from February 15, 2021 through August 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace.
The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit
access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements,
and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear
how other healthcare reform measures of the Biden administration or other efforts, if any, to challenge, repeal or replace the ACA will
impact our business. Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. The Budget
Control Act of 2011 and subsequent legislation, among other things, created measures for spending reductions that resulted in aggregate
reductions of Medicare payments to providers up to 2% per fiscal year, which, due to subsequent legislative amendments, will remain in
effect through 2030 unless additional Congressional action is taken.
In August 2022, the Inflation
Reduction Act of 2022, or the IRA, was signed into law. The IRA includes several provisions that may impact our business, depending on
how various aspects of the IRA are implemented. Provisions that may impact our business include a $2,000 out-of-pocket cap
for Medicare Part D beneficiaries, the imposition of new manufacturer financial liability on most drugs in Medicare Part D, permitting
the U.S. government to negotiate Medicare Part B and Part D pricing for certain high-cost drugs and biologics without generic or biosimilar
competition, requiring companies to pay rebates to Medicare for drug prices that increase faster than inflation, and delaying the rebate
rule that would require pass through of pharmacy benefit manager rebates to beneficiaries. In August 2023, the government selected the
first 10 drugs to be put through the Medicare drug price negotiation program, which is currently subject to several constitutional challenges.
The outcomes of these challenges on the IRA, and the effect of the IRA on our business and the healthcare industry in general, are not
yet known.
There has been increasing
legislative and enforcement interest in the United States with respect to product pricing practices. Specifically, there have been several
recent U.S. Congressional inquiries and proposed federal and state legislation designed to, among other things, bring more transparency
to product pricing, reduce the cost of products under Medicare, review the relationship between pricing and manufacturer patient programs,
and reform government program reimbursement methodologies for drugs. The U.S. Department of Health and Hman Services ("HHS")
has already started the process of soliciting feedback on some of these measures and, at the same time, is immediately implementing others
under its existing authority. It is unclear what effect such legislative and enforcement interest may have on prescription devices.
We expect that these and
other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional downward
pressure on the price that we receive for any marketed product, which could have an adverse effect on patients for our product candidates.
Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private
payers.
There have been, and likely
will continue to be, legislative and regulatory proposals at the foreign, federal and state levels in the U.S. directed at broadening
the availability of healthcare and containing or lowering the cost of healthcare. The implementation of cost containment measures or
other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our products. Such
reforms could have an adverse effect on anticipated revenue from products that we may successfully develop and for which we may obtain
regulatory marketing authorization and may affect our overall financial condition and ability to develop product candidates. If we or
any third parties we may engage are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or
policies, or if we or such third parties are not able to maintain regulatory compliance, our current or any future product candidates
we may develop may lose any regulatory marketing authorization that may have been obtained and we may not achieve or sustain profitability.
36
In the United States, there
have been and continue to be a number of legislative initiatives to contain healthcare costs. For example, in March 2010, the ACA was
enacted, which substantially changed the way health care is financed by both governmental and private insurers, and significantly impacted
the U.S. pharmaceutical industry. The ACA, among other things, subjected therapeutic biologics to potential competition by lower-cost
biosimilars, addressed a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated
for drugs and therapeutic biologics that are inhaled, infused, instilled, implanted or injected, increased the minimum Medicaid rebates
owed by manufacturers under the Medicaid Drug Rebate Program, extended the rebate program to individuals enrolled in Medicaid managed
care organizations, established annual fees and taxes on manufacturers of certain branded prescription drugs and therapeutic biologics
and added a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% point-of-sale discounts
off negotiated prices of applicable brand drugs and therapeutic biologics to eligible beneficiaries during their coverage gap period
as a condition for the manufacturer's outpatient drugs and therapeutic biologics to be covered under Medicare Part D.
However, some provisions
of the ACA have yet to be fully implemented and certain provisions have been subject to judicial and Congressional challenges, as well
as efforts by the Trump Administration to repeal or replace certain aspects of the ACA. For example, since January 2017, President Trump
has signed two executive orders and other directives designed to delay, circumvent, or loosen certain requirements mandated by the ACA.
Concurrently, Congress has considered legislation that would repeal or repeal and replace all or part of the ACA. On December 20,
2017, Congress passed The Tax Cuts and Jobs Act, which includes a provision repealing the individual mandate under the ACA, effective
January 1, 2019. We continue to evaluate how the ACA and recent efforts to repeal and replace or limit the implementation of the
ACA will impact our business.
In addition, other legislative
changes have been proposed and adopted in the United States since the ACA was enacted. On August 2, 2011, the Budget Control Act
of 2011 among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked
with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required
goals, thereby triggering the legislation's automatic reduction to several government programs. This includes aggregate reductions
of Medicare payments to providers of 2% per fiscal year. These reductions went into effect on April 1, 2013 and, due to subsequent
legislative amendments to the statute, will remain in effect through 2024 unless additional Congressional action is taken. On January 2,
2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several
types of providers. Additionally, there has been heightened governmental scrutiny recently over the manner in which manufacturers set
prices for their marketed products. For example, there have been several recent Congressional inquiries and proposed and enacted federal
and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing
and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. These new laws and initiatives
may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on our future
customers and accordingly, our financial operations.
Further, on December 13,
2016, President Obama signed the 21st Century Cures Act (the "Cures Act"), into law. Among other provisions, the Cures Act
reauthorized the existing priority review voucher program for certain drugs intended to treat rare pediatric diseases until 2020; created
a new priority review voucher program for drug applications determined to be material national security threat medical countermeasure
applications; revised the FDCA to streamline review of combination product applications; required FDA to evaluate the potential use of
"real world evidence" to help support approval of new indications for approved drugs; provided a new "limited population"
approval pathway for antibiotic and antifungal drugs intended to treat serious or life-threatening infections; and authorized FDA to
designate a drug as a "regenerative advanced therapy," thereby making it eligible for certain expedited review and approval
designations.
We expect that additional
state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state
governments will pay for healthcare products and services, which could result in reduced demand for our product candidates or additional
pricing pressures.
37
If we or existing or future partners, manufacturers
or service providers fail to comply with healthcare laws and regulations, we or they could be subject to enforcement actions, which could
affect our ability to develop, market and sell our products and may harm our reputation.
Healthcare providers, physicians
and third-party payors, among others, will play a primary role in the prescription and recommendation of any product candidates for which
we obtain marketing approval. Our future arrangements with third-party payors and customers, among others, may expose us to broadly applicable
fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships
through which we market, sell and distribute our product candidates for which we obtain marketing approval. Restrictions under applicable
federal and state healthcare laws and regulations, include the following:
●
the
federal Anti-Kickback Statute, which prohibits, among other things, a person or entity from knowingly and willfully soliciting, offering,
paying, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an
individual for, or the purchase, lease order, arranging for or recommendation of, any good, facility, item or service, for which payment
may be made, in whole or in part, by a federal healthcare program, such as Medicare or Medicaid. A person or entity does not need to
have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. Violation of the federal
Anti-Kickback Statue carries criminal penalties and fines as well as administrative sanctions under the Civil Money Penalties Law. In
addition, a violation of the Anti-Kickback Statute can form the basis for a violation of the federal False Claims Act;
●
the
federal civil and criminal false claims laws, including the federal False Claims Act, and civil monetary penalties laws that impose criminal
and civil penalties, including through civil whistleblower or qui tam actions, against individuals or entities for knowingly presenting,
or causing to be presented, to the federal government, claims for payment that are false or fraudulent or making a false statement to
avoid, decrease or conceal an obligation to pay money to the federal government. In addition, the government may assert that a claim
including items and services resulting from a referral made in violation of the federal Anti-Kickback Statute constitutes a false or
fraudulent claim for purposes of the federal False Claims Act;
●
the
U.S. federal Health Insurance Portability and Accountability Act of 1996 ("HIPAA"), which imposes criminal and civil liability
for executing a scheme to defraud any healthcare benefit program, or knowingly and willfully falsifying, concealing or covering up a
material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or
services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific
intent to violate it in order to have committed a violation;
●
HIPAA,
as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 ("HITECH"), and its implementing
regulations, including the Final Omnibus Rule published in January 2013, which impose obligations on certain covered entity healthcare
providers, health plans, and healthcare clearinghouse as well as their business associates that perform certain services involving the
use or disclosure of individually identifiable health information, including mandatory contractual terms, with respect to safeguarding
the privacy, security, and transmission of individually identifiable health information, and require notification to affected individuals
and regulatory authorities of certain breaches of security of individually identifiable health information;
●
the
federal false statements statute, which prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making
any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services;
●
the
federal transparency requirements known as the federal Physician Payments Sunshine Act, created as part of ACA, which requires certain
manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicare or the Children's
Health Insurance Program to report annually to CMS information related to payments and other transfers of value made by that entity to
physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members;
and
38
●
the
analogous local, state and foreign laws and regulations, such as state anti-kickback and false claims laws that may apply to healthcare
items or services reimbursed by third-party payors, including private insurers; local, state and foreign transparency laws that require
manufacturers to report information related to payments and transfers of value to other health care providers and health care entities,
or marketing expenditures; state laws that require pharmaceutical companies to register certain employees engaged in marketing activities
in the location and comply with the pharmaceutical industry's voluntary compliance guidelines and the relevant compliance guidance
promulgated by the federal government; and state and foreign laws governing the privacy and security of health information in certain
circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance
efforts.
Ensuring that our future
business arrangements with third parties comply with applicable healthcare laws and regulations could involve substantial costs. If our
operations are found to be in violation of any such requirements, we may be subject to penalties, including criminal and significant
civil monetary penalties, damages, fines, individual imprisonment, disgorgement, contractual damages, reputational harm, exclusion from
participation in government healthcare programs, integrity obligations, injunctions, recall or seizure of products, total or partial
suspension of production, denial or withdrawal of pre-marketing product approvals, private qui tam actions brought by individual
whistleblowers in the name of the government, refusal to allow us to enter into supply contracts, including government contracts, and
the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results
of operations. Although effective compliance programs can mitigate the risk of investigation and prosecution for violations of these
laws, these risks cannot be entirely eliminated. Any action against us for an alleged or suspected violation could cause us to incur
significant legal expenses and could divert our management's attention from the operation of our business, even if our defense
is successful. In addition, achieving and sustaining compliance with applicable laws and regulations may be costly to us in terms of
money, time and resources.
If we fail to comply with U.S. and foreign
regulatory requirements, regulatory authorities could limit or withdraw any marketing or commercialization approvals we may receive and
subject us to other penalties that could materially harm our business.
Even if we receive marketing
and commercialization approval of a product candidate, we will be subject to continuing regulatory requirements, including in relation
to adverse patient experiences with the product and clinical results that are reported after a product is made commercially available,
both in the United States and any foreign jurisdiction in which we seek regulatory approval. The FDA has significant post-market authority,
including the authority to require labeling changes based on new safety information and to require post-market studies or clinical trials
to evaluate safety risks related to the use of a product or to require withdrawal of the product from the market. The FDA also has the
authority to require a Risk Evaluation and Mitigation Strategy (a "REMS"), after approval, which may impose further requirements
or restrictions on the distribution or use of an approved drug or therapeutic biologic. The manufacturer and manufacturing facilities
we use to make a future product, if any, will also be subject to periodic review and inspection by the FDA and other regulatory agencies,
including for continued compliance with cGMP requirements. The discovery of any new or previously unknown problems with our third-party
manufacturers, manufacturing processes or facilities may result in restrictions on the product, manufacturer or facility, including withdrawal
of the product from the market. We intend to rely on third-party manufacturers and we will not have control over compliance with applicable
rules and regulations by such manufacturers. Any product promotion and advertising will also be subject to regulatory requirements and
continuing regulatory review. If we or our existing or future partners, manufacturers or service providers fail to comply with applicable
continuing regulatory requirements in the U.S. or foreign jurisdictions in which we seek to market our products, we or they may be subject
to, among other things, fines, warning letters, holds on clinical trials, delay of approval or refusal by the FDA to approve pending
applications or supplements to approved applications, suspension or withdrawal of regulatory approval, product recalls and seizures,
administrative detention of products, refusal to permit the import or export of products, operating restrictions, injunction, civil penalties
and criminal prosecution.
39
Even if we are able to commercialize any
product candidate, such product candidate may become subject to unfavorable pricing regulations or third-party coverage and reimbursement
policies, which would harm our business.
Our ability to commercialize
any products successfully will depend, in part, on the extent to which coverage and adequate reimbursement for these products and related
treatments will be available from third-party payors, such as government authorities, private health insurers, and health maintenance
organizations. Patients who are prescribed medications for the treatment of their conditions generally rely on third-party payors to
reimburse all or part of the costs associated with their prescription drugs. Coverage and adequate reimbursement from government healthcare
programs, such as Medicare and Medicaid, and private health insurers are critical to new product acceptance. Patients are unlikely to
use our future product candidates unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost
of our product candidates.
Cost-containment is a priority
in the U.S. healthcare industry and elsewhere. As a result, government authorities and other third-party payors have attempted to control
costs by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring
that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products.
Third-party payors also may request additional clinical evidence beyond the data required to obtain marketing approval, requiring a company
to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of its product. We
cannot be sure that coverage and adequate reimbursement will be available for any product that we commercialize and, if reimbursement
is available, that the level of reimbursement will be adequate. Coverage and reimbursement may impact the demand for, or the price of,
any product candidate for which we obtain marketing approval. If coverage and reimbursement are not available or are available only at
limited levels, we may not be able to successfully commercialize any product candidate for which we obtain marketing approval.
Additionally, the regulations
that govern regulatory approvals, pricing and reimbursement for new drugs and therapeutic biologics vary widely from country to country.
Some countries require approval of the sale price of a drug or therapeutic biologic before it can be marketed. In many countries, the
pricing review period begins after marketing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains
subject to continuing governmental control even after initial approval is granted. As a result, we might obtain regulatory approval for
a product in a particular country, but then be subject to price regulations that delay our commercial launch of the product, possibly
for lengthy time periods and negatively impact the revenues we are able to generate from the sale of the product in that country. Adverse
pricing limitations may hinder our ability to recoup our investment in one or more product candidates, even if our product candidates
obtain regulatory approval.
We are subject to U.S. and foreign anti-corruption
and anti-money laundering laws with respect to our operations and non-compliance with such laws can subject us to criminal
and/or civil liability and harm our business.
We are subject to the U.S.
Foreign Corrupt Practices Act of 1977, as amended (the "FCPA"), the U.S. domestic bribery statute contained in 18 U.S.C.
§ 201, the U.S. Travel Act, the USA PATRIOT Act, and possibly other state and national anti-bribery and anti-money laundering laws
in countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees,
agents, third-party intermediaries, joint venture partners and collaborators from authorizing, promising, offering, or providing, directly
or indirectly, improper payments or benefits to recipients in the public or private sector. We interact with officials and employees
of
government agencies and government-affiliated hospitals, universities, and other organizations. In addition, we may engage
third-party intermediaries to promote our clinical research activities abroad and/or to obtain necessary permits, licenses, and other
regulatory approvals. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees,
representatives, contractors, partners, and agents, even if we do not explicitly authorize or have actual knowledge of such activities.
We will adopt a Code of Business Conduct and Ethics, which will be effective upon the Closing of the Business Combination, and expect
to prepare and implement policies and procedures to ensure compliance with such code. The Code of Business Conduct and Ethics mandates
compliance with the FCPA and other anti-corruption laws applicable to our business throughout the world. However, we cannot assure you
that our employees and third-party intermediaries will comply with this code or such anti-corruption laws. Noncompliance with anti-corruption
and anti-money laundering laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, other
enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension
and/or debarment from contracting with certain persons, the loss of export privileges, reputational harm, adverse media coverage, and
other collateral consequences. If any subpoenas, investigations, or other enforcement actions are launched, or governmental or other
sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations and
financial condition could be materially harmed. In addition, responding to any action will likely result in a materially significant
diversion of management's attention and resources and significant defense and compliance costs and other professional fees. In
certain cases, enforcement authorities may even cause us to appoint an independent compliance monitor which can result in added costs
and administrative burdens.
40
Comprehensive tax reform bills could adversely affect our business
and financial condition.
The U.S. government is in
the process of enacting comprehensive tax legislation that includes significant changes to the taxation of business entities. These changes
include, among others, (i) a permanent reduction to the corporate income tax rate, (ii) a partial limitation on the deductibility
of business interest expense, (iii) a shift of the U.S. taxation of multinational corporations from a tax on worldwide income to
a territorial system (along with certain rules designed to prevent erosion of the U.S. income tax base) and (iv) a one-time tax
on accumulated offshore earnings held in cash and illiquid assets, with the latter taxed at a lower rate. Notwithstanding the reduction
in the corporate income tax rate, the overall impact of this tax reform is uncertain, and our business and financial condition could
be adversely affected. This proxy statement/prospectus does not discuss any such tax legislation or the manner in which it might affect
purchasers of our common stock. We urge our stockholders to consult with their legal and tax advisors with respect to any such legislation
and the potential tax consequences of investing in our common stock.
Our ability to utilize our net operating
loss carryforwards and certain other tax attributes may be limited.
Under Sections 382 and 383
of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an "ownership change" (generally defined as
a greater than 50 percentage points change (by value) in the ownership of its equity over a rolling three-year period), the corporation's
ability to use its pre-change net operating loss carryforwards and certain other pre-change tax attributes to offset
its post-change income and taxes may be limited.
We may have experienced such
ownership changes in the past, and we may experience ownership changes in the future, some of which are outside of our control. As of
December 31, 2023, we had federal net operating loss carryforwards of approximately $74.9 million, and our ability to utilize
those net operating loss carryforwards could be limited by an "ownership change" as described above, which could result in
increased tax liability to our company.
Risks Related to Our Organization and Structure
Our Charter and the Bylaws provide that
the Court of Chancery of the State of Delaware is the sole and exclusive forum for substantially all disputes between us and our stockholders,
which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers,
or employees.
Our Charter and the Bylaws
provide that, unless we consent in writing to the selection of an alternative forum, the (a) Court of Chancery (the "Chancery
Court") of the State of Delaware (or, in the event that the Chancery Court does not have jurisdiction, the federal district court
for the District of Delaware or other state courts of the State of Delaware) shall, to the fullest extent permitted by law, be the sole
and exclusive forum for: (i) any derivative action, suit or proceeding brought on our behalf; (ii) any action, suit or proceeding
asserting a claim of breach of fiduciary duty owed by any of our directors, officers, or stockholders to us or to our stockholders; (iii) any
action, suit or proceeding asserting a claim arising pursuant to the DGCL, the Charter or the Bylaws; or (iv) any action, suit or
proceeding asserting a claim governed by the internal affairs doctrine; and (b) subject to the foregoing, the federal district courts
of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising
under the Securities Act. Notwithstanding the foregoing, such forum selection provisions shall not apply to suits brought to enforce
any liability or duty created by the Exchange Act or any other claim for which the federal courts of the United States have exclusive
jurisdiction. The exclusive forum provision may increase the costs for a stockholder to bring a claim or limit a stockholder's
ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees,
which may discourage such lawsuits against us and our directors, officers, and other employees. Alternatively, if a court were to find
the choice of forum provision contained in the Charter to be inapplicable or unenforceable in an action, we may incur additional costs
associated with resolving such action in other jurisdictions, which could harm our business, results of operations, and financial condition.
41
Additionally, Section 22
of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability
created by the Securities Act or the rules and regulations thereunder. As noted above, our Charter and the Bylaws provide that the federal
district courts of the United States of America shall have jurisdiction over any action arising under the Securities Act. Accordingly,
there is uncertainty as to whether a court would enforce such provision. Our stockholders will not be deemed to have waived our compliance
with the federal securities laws and the rules and regulations thereunder.
Anti-takeover provisions in our governing
documents and under Delaware law could make an acquisition of us more difficult, limit attempts by our stockholders to replace or remove
our current management and limit the market price of our common stock.
The Charter, the Bylaws and
Delaware law contain provisions that could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed
undesirable by our Board. Among other things, the Charter and/or Bylaws include the following provisions:
●
a
staggered board, which means that our Board is classified into three classes of directors with staggered three-year terms and directors
are only able to be removed from office for cause;
●
limitations
on convening special stockholder meetings, which could make it difficult for our stockholders to adopt desired governance changes;
●
a
prohibition on stockholder action by written consent, which means that our stockholders will only be able to take action at a meeting
of stockholders and will not be able to take action by written consent for any matter;
●
a
forum selection clause, which means certain litigation against us can only be brought in Delaware;
●
the
authorization of undesignated preferred stock, the terms of which may be established and shares of which may be issued without further
action by our stockholders; and
●
advance
notice procedures, which apply for stockholders to nominate candidates for election as directors or to bring matters before an annual
meeting of stockholders.
These provisions, alone or
together, could delay or prevent hostile takeovers and changes in control or changes in our management. As a Delaware corporation, we
are also subject to provisions of Delaware law, including Section 203 of the DGCL, which prevents interested stockholders, such
as certain stockholders holding more than 15% of our outstanding common stock, from engaging in certain business combinations unless
(i) prior to the time such stockholder became an interested stockholder, the board of directors approved the transaction that resulted
in such stockholder becoming an interested stockholder, (ii) upon consummation of the transaction that resulted in such stockholder
becoming an interested stockholder, the interested stockholder owned at least 85% of the common stock, or (iii) following board
approval, such business combination receives the approval of the holders of at least two-thirds of our outstanding common stock
not held by such interested stockholder at an annual or special meeting of stockholders.
Any provision of the Charter,
the Bylaws or Delaware law that has the effect of delaying, preventing or deterring a change in control could limit the opportunity for
our stockholders to receive a premium for their shares of our common stock and could also affect the price that some investors are willing
to pay for our common stock.
Our management team may not successfully or efficiently manage
its transition to being a public company.
As a public company, we have
incurred new obligations relating to our reporting, procedures, and internal controls. These new obligations and attendant scrutiny will
require investments of significant time and energy from our executives and could divert their attention away from the day-to-day
management of our business, which in turn could adversely affect our financial condition or operating results.
The members of our management
team have extensive experience leading complex organizations. However, they have limited experience managing a publicly traded company,
interacting with public company investors, and complying with the increasingly complex laws, rules and regulations that specifically
govern public companies.
42
We will incur significant increased expenses
and administrative burdens as a public company, which could have an adverse effect on its business, financial condition and results of
operations.
As a result of the consummation
of the Business Combination, we face increased legal, accounting, administrative and other costs and expenses as a public company that
we did not incur as a private company. The Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act"), including the
requirements of Section 404, as well as rules and regulations subsequently implemented by the SEC, the Dodd-Frank Wall Street Reform
and Consumer Protection Act of 2010 and the rules and regulations promulgated and to be promulgated thereunder, Public Company
Accounting Oversight Board (the "PCAOB") and the securities exchanges, impose additional reporting and other obligations on
public companies. Compliance with public company requirements will increase costs and make certain activities more time-consuming. A number
of those requirements have and will require us to carry out activities we have not done previously. For example, we have created new Board
committees and will adopt new internal controls and disclosure controls and procedures. In addition, expenses associated with SEC reporting
requirements will be incurred. Furthermore, if any issues in complying with those requirements are identified, we could incur additional
costs rectifying those issues, and the existence of those issues could adversely affect our reputation or investor perceptions of us.
It may also be more expensive to obtain director and officer liability insurance. Risks associated with our status as a public company
may make it more difficult to attract and retain qualified persons to serve on the Board or as executive officers. The additional reporting
and other obligations imposed by these rules and regulations will increase legal and financial compliance costs and the costs of related
legal, accounting and administrative activities. These increased costs will require us to divert a significant amount of money that could
otherwise be used to expand the business and achieve strategic objectives. Advocacy efforts by stockholders and third parties may also
prompt additional changes in governance and reporting requirements, which could further increase costs.
In addition, the need to establish
the corporate infrastructure demanded of a public company may also divert management's attention from implementing our business
strategy, which could prevent us from improving our business, results of operations and financial condition. We have made, and will continue
to make, changes to our internal control over financial reporting, including IT controls, and procedures for financial reporting and accounting
systems to meet our reporting obligations as a public company. However, the measures we take may not be sufficient to satisfy our obligations
as a public company. If we do not continue to develop and implement the right processes and tools to manage our changing enterprise and
maintain our culture, our ability to compete successfully and achieve our business objectives could be impaired, which could negatively
impact our business, financial condition and results of operations. In addition, we cannot predict or estimate the amount of additional
costs we may incur to comply with these requirements. We anticipate that these costs will materially increase our general and administrative
expenses.
We have concluded that our disclosure controls
and procedures were not effective as of December 31, 2023. If we are unable to develop and maintain an effective system of internal
control over financial reporting, we may not be able to accurately report our financial results in a timely manner, which may adversely
affect investor confidence in us and materially and adversely affect our business and operating results.
We concluded that our internal
control over financial reporting was ineffective as of December 31, 2023 because a material weakness existed in our internal control
over financial reporting. Management identified errors related to the completeness and accuracy of financial data, relating to unrecorded
liabilities as of December 31, 2023. These errors were corrected prior to the issuance of the consolidated financial statements for
the year ended December 31, 2023.
Effective internal controls
are necessary for us to provide reliable financial reports and prevent fraud. We continue to evaluate steps to improve our internal control
over financial reporting. These remediation measures may be time consuming and costly, and there is no assurance that these initiatives
will ultimately have the intended effects.
43
A material weakness in internal
control over financial reporting is a deficiency, or a combination of deficiencies, such that there is a reasonable possibility that a
material misstatement of our annual or interim financial statements will not be prevented, or detected and corrected on a timely basis.
If we identify any material weaknesses in internal control over financial reporting, any such material weakness could limit our ability
to prevent or detect a misstatement of our accounts or disclosures that could result in a material misstatement of our annual or interim
financial statements. In such case, we may be unable to maintain compliance with securities law requirements regarding timely filing of
periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting
and our stock price may decline as a result. We cannot assure you that the measures we have taken to date, or any measures we may take
in the future, will be sufficient to avoid potential future material weaknesses.
To address this material weakness,
management has devoted, and plans to continue to devote, significant effort and resources to the remediation and improvement of its internal
controls over financial reporting, including the addition of qualified accounting personnel in charge of period-end close procedures,
accrued liability estimates, and improvement of internal communications within the Company as it relates to the impact of new and outstanding
contractual arrangements. We can offer no assurance that these initiatives will ultimately have the intended effects.
Our disclosure controls and procedures may
not prevent or detect all errors or acts of fraud.
We designed our disclosure
controls and procedures to reasonably assure that information we must disclose in reports we file or submit under the Exchange Act is
accumulated and communicated to management, and recorded, processed, summarized and reported within the time periods specified in the
rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how
well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. These
inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple
error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people
or by an unauthorized override of the controls.
44
Changes in accounting rules and regulations,
or interpretations thereof, could result in unfavorable accounting charges or require us to change our compensation policies.
Accounting methods and policies
for public companies are subject to review, interpretation and guidance from our independent registered accounting firm and relevant accounting
authorities, including the SEC. Changes to accounting methods or policies, or interpretations thereof, may require us to reclassify, restate
or otherwise change or revise our consolidated financial statements.
We will need to improve our operational
and financial systems to support our expected growth, increasingly complex business arrangements, and rules governing revenue and expense
recognition and any inability to do so will adversely affect our billing and reporting.
To manage the expected growth
of our operations and increasing complexity, we will need to improve our operational and financial systems, procedures, and controls and
continue to increase systems automation to reduce reliance on manual operations. Any inability to do so will affect our manufacturing
operations, customer billing and reporting. Our current and planned systems, procedures and controls may not be adequate to support our
complex arrangements and the rules governing revenue and expense recognition for our future operations and expected growth. Delays or
problems associated with any improvement or expansion of our operational and financial systems and controls could adversely affect our
relationships with our customers, cause harm to our reputation and brand and could also result in errors in our financial and other reporting.
We expect that complying with these rules and regulations will substantially increase our legal and financial compliance costs and will
make some activities more time-consuming and costly. These increased costs will increase our net loss and we cannot predict or estimate
the amount or timing of additional costs we may incur to respond to these requirements.
Our management has limited experience in
operating a U.S.-listed public company.
Our management has limited
experience in the management of a U.S.-listed public company. Our management team may not successfully or effectively manage our transition
to a U.S.-listed public company that will be subject to significant regulatory oversight and reporting obligations under federal securities
laws. Their limited experience in dealing with the increasingly complex laws pertaining to public companies could be a significant disadvantage
in that it is likely that an increasing amount of their time may be devoted to these activities which will result in less time being devoted
to the management and growth of the combined company. We may not have adequate personnel with the appropriate level of knowledge, experience,
and training in the accounting policies, practices or internal controls over financial reporting required of U.S.-listed public companies.
The development and implementation of the standards and controls necessary for the combined company to achieve the level of accounting
standards required of a public company listed on a public exchange in the United States may require costs greater than expected.
It is possible that we will be required to expand our employee base and hire additional employees to support our operations as a public
company, which will increase our operating costs in future periods.
We are an "emerging growth company,"
and our reduced SEC reporting requirements may make our shares less attractive to investors.
We are an "emerging
growth company" as defined in the Jumpstart Our Business Startups Act of 2012 ("JOBS Act"). We will remain
an "emerging growth company" until the earliest to occur of (i) the last day of the fiscal year (a) following
the fifth anniversary of the of the date of the completion of the ACAB IPO, (b) in which we have total annual gross revenue of at
least $1.235 billion or (c) in which we are deemed to be a large accelerated filer, which means the market value of our Common
Stock held by non-affiliates exceeds $700 million as of the last business day of our prior second fiscal quarter, and (ii) the
date on which we issued more than $1.0 billion in non-convertible debt during the prior three-year period. We intend to take advantage
of exemptions from various reporting requirements that are applicable to most other public companies, such as an exemption from the provisions
of Section 404(b) of the Sarbanes-Oxley Act requiring our independent registered public accounting firm provide an attestation
report on the effectiveness of our internal control over financial reporting and reduced disclosure obligations regarding executive compensation
in our periodic reports and proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation
and shareholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our shares
less attractive because we intend to rely on certain of these exemptions and benefits under the JOBS Act. If some investors find our shares
less attractive as a result, there may be a less active, liquid and/or orderly trading market for our shares and the market price and
trading volume of our shares may be more volatile and decline significantly.
45
Risks Related to an Investment in of Our Securities
An active market for our securities may not develop, which would
adversely affect the liquidity and price of our securities.
The price of our securities
may vary significantly due to factors specific to us as well as to general market or economic conditions. Furthermore, an active trading
market for our securities may never develop or, if developed, it may not be sustained. You may be unable to sell your securities unless
a market can be established and sustained.
Our failure to meet Nasdaq's continued listing requirements
could result in a delisting of our shares.
If we fail to satisfy Nasdaq's
continued listing requirements, such as the corporate governance requirements or the minimum closing bid price requirement, Nasdaq may
take steps to delist our shares. Such a delisting would likely have a negative effect on the price of our shares and would impair your
ability to sell or purchase our shares when you wish to do so. In the event of a delisting, we can provide no assurance that any action
taken by us to restore compliance with listing requirements would allow our shares to become listed again, stabilize the market price
or improve the liquidity of our shares, prevent our shares from dropping below Nasdaq's minimum bid price requirement or prevent
future non-compliance with Nasdaq's listing requirements.
If Nasdaq delists our securities
from trading on its exchange and we are not able to list our securities on another national securities exchange, we expect our securities
could be quoted on an over-the-counter market. If this were to occur, we could face significant material adverse consequences, including:
●
a limited availability of market quotations for our securities;
●
reduced liquidity for our securities;
●
a determination that our Common Stock is "penny stock" which will require brokers trading in the Common Stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for our securities;
●
a limited amount of news and analyst coverage; and
●
a decreased ability to issue additional securities or obtain additional financing in the future.
The Common Stock being registered in this
prospectus represent a substantial percentage of our public float and of our outstanding Common Stock, and the sale of such shares could
cause the market price of Common Stock to decline significantly.
This
prospectus also relates to the offer and resale from time to time, upon the expiration of lock-up agreements, if applicable, by the Selling
Securityholders of (a) of up to an aggregate of 31,785,312 shares of Common Stock, consisting of (i) an aggregate of 1,122,467
shares of Common Stock, issued in the PIPE Offering to the PIPE Investors pursuant to the terms of individual subscription agreements,
in connection with the Business Combination at $10.00 per share, (ii) an aggregate of 2,244,934 shares of Common Stock issued to
the PIPE Investors as incentive shares for participating in the PIPE Offering for no additional consideration, (iii) 350,000 shares of

fees at a value of $10.00 per share, (vii) 360,000 shares of Common Stock issued to Polar Multi-Strategy Master Fund at a value of $10.00
per share in satisfaction of an outstanding loan, (viii) 200,000 shares to Cohen at a value of $10.00 per share, (ix) 600,601 shares of
Common Stock issued to the Sponsor in satisfaction of a working capital note issued to ACAB for aggregate consideration of approximately
$2.0 million, or approximately $3.33 per share, and (x) 600,000 shares of Common Stock issued to Mr. Chan, New Abpro's Chief Executive
Officer, in satisfaction of an approximately $2.0 million promissory note of Abpro Corporation, at a value of $3.33 per share, (xi) an
aggregate of 5,973,558 shares of Common Stock that were originally issued as ACAB's Series B common stock that were subsequently
converted into ACAB's Series A common stock on April 18, 2023, consisting of (A) 5,673,558 shares of Common Stock originally
issued to the Sponsor at a value of $0.0035 per share, comprised of (w) 983,333 shares of which were transferred to Abpro Bio International,
Inc. ("
Abpro Bio
") in connection with Closing, (x) 983,333 shares of which were transferred to Abpro Corporation's
designees in connection with Closing, (y) 825,225 shares of which were transferred to ACAB's designees in connection with Closing,
and (z) 2,881,667 shares retained by the Sponsor, (B) 50,000 shares of Common Stock issued to Apeiron Investment Group Ltd. at a value
of $7.25 per share, and (C) 250,000 shares of Common Stock transferred from the Sponsor to former directors of ACAB for no additional
consideration on October 25, 2021, (xii) an aggregate of 9,498,900 shares of Common Stock issued as Merger Consideration (defined below)
to officers and directors of the Company at a value of $10.00 per share, (xiii) up to 10,102,000 shares of Common Stock issuable pursuant
to the SEPA with Yorkville, which represents the number of shares of Common Stock representing the Exchange Cap (as defined in the SEPA),
including 297,160 shares of Common Stock issued to Yorkville as commitment shares pursuant to the terms of the SEPA (the "Commitment
Shares"); and (b) the Selling Warrantholders named in this prospectus of up to an aggregate of 13,850,000 Placement Warrants.
The Common Stock being registered
for resale in this prospectus represent a substantial percentage of our public float and of our outstanding Common Stock. The number of
shares being registered in this prospectus (which include shares issuable upon exercise of the Warrants and shares issuable pursuant to
the SEPA) represents approximately 117.0% of the total Common Stock outstanding as of December 23, 2024, which was 51,815,765 shares of
Common Stock. In addition, the securities beneficially owned by the Sponsor represent approximately 6.7% of the total Common Stock outstanding,
and this holder will have the ability to sell all of its shares pursuant to the registration statement of which this prospectus forms
a part so long as it is available for use upon expiration of the six month lockup period. The sale of the securities being registered
in this prospectus, or the perception in the market that such sales may occur, could result in a significant decline in the public trading
price of our Common Stock.
46
In addition, some of the shares
being registered for resale were acquired by the Selling Securityholders for nominal consideration or purchased for prices considerably
below the current market price of the Common Stock. Even though the current market price is significantly below the price at the time
of the ACAB IPO, certain Selling Securityholders have an incentive to sell because they will still profit on sales due to the lower price
at which they acquired their shares as compared to the public investors. In particular, the Sponsor may experience a positive rate of
return on the securities they purchased due to the differences in the purchase prices described above, to the extent they acquired such
securities for less than the relevant trading price, and the public securityholders may not experience a similar rate of return on the
securities they purchased due to the differences in the purchase prices described above. Based on the last reported sale price of Common
Stock of $2.07 on December 20, 2024, shares acquired for less than such last reported sale price, the Selling Securityholders may experience
potential profit up to $2.07 per share.
The market price of our Common Stock may
decline following the Business Combination.
The market price of our Common
Stock may decline following the Business Combination for a number of reasons including if:
●
investors react negatively to the prospects of our business;
●
the effect of the Business Combination on our business and prospects is not consistent with the expectations of financial or industry analysts; or
●
we do not achieve the perceived benefits of the Business Combination as rapidly or to the extent anticipated by financial or industry analysts.
If securities or industry analysts do not
publish research or reports about our business or publish negative reports about our business, our share price and trading volume could
decline.
The trading market for our
shares will depend on the research and reports that securities or industry analysts publish about us or our business. Currently, we do
not have any analyst coverage and may not obtain analyst coverage in the future. In the event we obtains analyst coverage, we will not
have any control over such analysts. If one or more of the analysts who cover us downgrade our shares or change their opinion of our shares,
the share price would likely decline. If one or more of these analysts cease coverage of us or we or fail to regularly publish reports
on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.
Our Common Share price may decline and you
could lose all or part of your investment as a result.
The trading price of our Common
Stock is likely to be volatile. The stock market recently has experienced extreme volatility. This volatility often has been unrelated
or disproportionate to the operating performance of particular companies. You may not be able to resell your Common Stock at an attractive
price due to a number of factors such as those listed in "—
Risks Related to Our Business and Industry
"
and the following:
●
results of operations that vary from the expectations of securities analysts and investors;
●
results of operations that vary from our competitors;
●
changes in expectations as to our future financial performance, including financial estimates and investment recommendations by securities analysts and investors;
●
declines in the market prices of stocks generally;
●
strategic actions by us or our competitors;
●
announcements by us or our competitors of significant contracts, acquisitions, joint ventures, other strategic relationships or capital commitments;
47
●
announcements of estimates by third parties of actual or anticipated changes in the size of our customer base or the level of customer engagement;
●
any significant change in our management;
●
changes in general economic or market conditions or trends in our industry or markets;
●
changes in business or regulatory conditions, including new laws or regulations or new interpretations of existing laws or regulations applicable to our business;
●
additional securities being sold or issued into the market by us or any of the existing shareholders or the anticipation of such sales, including if we issue shares to satisfy restricted stock unit related tax obligations or if existing shareholders sell shares into the market when applicable "lock-up" periods end;
●
investor perceptions of the investment opportunity associated with our Common Stock relative to other investment alternatives;
●
the public's response to press releases or other public announcements by us or third parties, including our filings with the SEC;
●
litigation involving us, our industry, or both, or investigations by regulators into our operations or those of our competitors;
●
guidance, if any, that we provide to the public, any changes in this guidance or our failure to meet this guidance;
●
the development and sustainability of an active trading market for our Common Stock;
●
the market's reaction to our reduced disclosure and other requirements as a result of being an "emerging growth company" under the Jumpstart Our Business Startups Act (the "JOBS Act");
●
the size of our public float;
●
actions by institutional or activist shareholders;
●
developments in new legislation and pending lawsuits or regulatory actions, including interim or final rulings by judicial or regulatory bodies;
●
changes in senior management or key personnel;
●
changes in accounting standards, policies, guidelines, interpretations or principles; and
●
other events or factors, including those resulting from pandemics, natural disasters, war, acts of terrorism or responses to these events.
These broad market and industry
fluctuations may adversely affect the market price of our Common Stock, regardless of our actual operating performance. In addition, price
volatility may be greater if the public float and trading volume of our Common Stock is low. In the past, following periods of market
volatility, shareholders have instituted securities class action litigation. If we are involved in securities litigation, it could have
a substantial cost and divert resources and the attention of executive management from our business regardless of the outcome of such
litigation.
48
Concentration of ownership among existing
executive officers, directors and their affiliates, including the investment funds they represent, may prevent new investors from influencing
significant corporate decisions.
Our executive officers, directors
and their affiliates, including the investment funds they represent, as a group beneficially own approximately 18.1% of New Abpro's
Common Stock. As a result, these stockholders will be able to exercise a significant level of control over all matters requiring stockholder
approval, including the election of directors, amendment of the Charter and approval of significant corporate transactions. This control
could have the effect of delaying or preventing a change of control of our company or changes in management and will make the approval
of certain transactions difficult or impossible without the support of these stockholders.
Because there are no current plans to pay
cash dividends on our Common Stock for the foreseeable future, you may not receive any return on investment unless you sell your Common
Stock at a price greater than what you paid for it.
We intend to retain future
earnings, if any, for future operations, expansion and debt repayment, and there are no current plans to pay any cash dividends for the
foreseeable future. The declaration, amount and payment of any future dividends on our Common Stock will be at the sole discretion of
our Board. Our Board may take into account general and economic conditions, our financial condition and results of operations, our available
cash and current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions, implications of
the payment of dividends by us to our shareholders or by our subsidiaries to us and such other factors as our Board may deem relevant.
As a result, you may not receive any return on an investment in our Common Stock unless you sell your Common Stock for a price greater
than that which you paid for it.
Our shareholders may experience dilution in the future.
The percentage of our Common
Stock owned by current shareholders may be diluted in the future because of equity issuances for acquisitions, capital market transactions
or otherwise, including, without limitation, equity awards that we may grant to our directors, officers and employees, exercise of our
warrants. Such issuances may have a dilutive effect on our earnings per share, which could adversely affect the market price of our Common
Stock.
If securities or industry analysts do not
publish research or reports about our business, if they change their recommendations regarding our Common Stock or if our operating results
do not meet their expectations, our Common Stock price and trading volume could decline.
The trading market for our
Common Stock will depend in part on the research and reports that securities or industry analysts publish about us or our businesses.
If no securities or industry analysts commence coverage of us, the trading price for our Common Stock could be negatively impacted. In
the event securities or industry analysts initiate coverage, if one or more of the analysts who cover us downgrade our securities or publish
unfavorable research about its businesses, or if our operating results do not meet analyst expectations, the trading price of our Common
Stock would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for
our Common Stock could decrease, which might cause our Common Share price and trading volume to decline.
Future sales, or the perception of future
sales, by us or our shareholders in the public market could cause the market price for our Common Stock to decline.
The sale of our Common Stock
in the public market, or the perception that such sales could occur, could harm the prevailing market price of our Common Stock. These
sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future
at a time and at a price that it deems appropriate.
In connection with the Business
Combination, pursuant to the Abpro Lock-Up Agreements, certain Abpro stockholders agreed that they will not, during the period
beginning at the Effective Time and continuing to and including the date that is one (1) year after the date of the Effective Time,
subject to earlier release conditions, directly or indirectly, offer, sell, contract to sell, pledge, grant any option to purchase, make
any short sale or otherwise dispose of any shares of Common Stock, or any options or warrants to purchase any shares of Common Stock,
or any securities convertible into, exchangeable for or that represent the right to receive shares of Common Stock, or any interest in
any of the foregoing (in each case, subject to certain exceptions set forth in the Abpro Lock-Up Agreements). The 600,601 Additional
Sponsor Shares issued to the Sponsor at Closing pursuant to Amendment No. 1 to the Business Combination Agreement are not subject to the
Abpro Lock-Up Agreements.
49
Upon the expiration or waiver
of the lock-ups described above, shares held by certain of our stockholders will be eligible for resale, subject to, in the
case of certain stockholders, volume, manner of sale and other limitations under Rule 144. In addition, pursuant to the Registration Rights
Agreement, the Selling Securityholders, by exercising their registration rights and selling a large number of shares, pursuant to the
registration statement of which this prospectus forms a part, could cause the prevailing market price of our Common Stock to decline.
The shares covered by registration rights represent approximately 15% of our outstanding common stock.
The sale of the securities being registered pursuant
to the registration statement of which this prospectus forms a part, or the perception in the market that such shales may occur, could
result in a significant decline in the market price of shares of our Common Stock. These factors could also make it more difficult for
us to raise additional funds through future offerings of our shares of Common Stock or other securities.
In addition, the shares of
our Common Stock reserved for future issuance under the New Abpro Incentive Plan will become eligible for sale in the public market once
those shares are issued, subject to provisions relating to various vesting agreements, lock-up agreements and, in some cases,
limitations on volume and manner of sale applicable to affiliates under Rule 144, as applicable. The number of shares reserved for future
issuance under the New Abpro Incentive Plan is 6,240,773 shares of Common Stock. In addition, the New Abpro Incentive Plan includes an
evergreen feature that will allow our Board, in its sole discretion, to reserve additional shares of Common Stock for future issuance
under the New Abpro Incentive Plan each calendar year, Beginning January 1, 2026 and ending on and including January 1, 2034 equal to
the lesser of 5% of the shares of Common Stock outstanding on the final day of the immediately preceding calendar year and a smaller number
of shares determined by the Board. We expect to file one or more registration statements on Form S-8 under the Securities Act
to register shares of our Common Stock or securities convertible into or exchangeable for shares of our Common Stock issued pursuant to
the New Abpro Incentive Plan. Any such Form S-8 registration statements will automatically become effective upon filing. Accordingly,
shares registered under such registration statements will be available for sale in the open market.
In the future, we may also
issue its securities in connection with investments or acquisitions. The amount of Common Stock issued in connection with an investment
or acquisition could constitute a material portion of the then-outstanding Common Stock. Any issuance of additional securities in connection
with investments or acquisitions may result in additional dilution to our shareholders.
Sales of our Common Stock, or the perception
of such sales, pursuant to the registration statement of which this prospectus forms a part may have negative pressure on the public trading
price of our Common Stock.
The Selling Securityholders
will determine the timing, pricing and rate at which they sell the shares being registered for resale on the registration statement of
which this prospectus forms a part into the public market. Significant sales of Common Stock pursuant to the registration statement of
which this prospectus forms a part may have negative pressure on the public trading price of our Common Stock. The number of shares being
registered in this prospectus (which include shares issuable upon exercise of the Warrants and shares issuable pursuant to the SEPA) represents
approximately 117.0% of the total Common Stock outstanding as of December 23, 2024, which was 51,815,765 shares of Common Stock. Also,
even though the current trading price is significantly below the Company's initial public offering price, based on the closing price
of our Common Stock on December 20, 2024, certain private investors may have an incentive to sell their shares, because they will still
profit on sales due to the lower prices at which they purchased their shares as compared to the public investors.
On December 20, 2024, the
closing price of the Common Stock was $2.07 per share. The initial public offering price of our units was $10.00 per unit, with each unit
consisting of one Common Share and one half of one Public Warrant to purchase one Common Share at an exercise price of $11.50 per share.
50
While certain Selling Securityholders
may experience a positive rate of return based on the current trading price of our Common Stock, public securityholders may not experience
a similar rate of return on the securities they purchased due to differences in the purchase prices and the current trading price of our
Common Stock. Based on the closing price of the Common Stock on December 20, 2024, which was $2.07 per share, and assuming the resale
by the Selling Securityholders of all 31,785,312 shares of Common Stock being registered on the registration statement of which this prospectus
forms a part, the Selling Securityholders could earn approximately $65.8 million in aggregate proceeds from the resale of such shares.
The PIPE Shares were purchased at an effective price of $10.00 per share, however, incentive shares transferred to such PIPE Investor
may meaningfully lower the per share price the PIPE Investor paid for his shares to approximately $3.33 (assuming the PIPE Investor had
retained all Incentive Shares). The Founder Shares were purchased for an aggregate price of $25,000, or $0.0035 per share, and, therefore,
based on the closing price of the Common Stock on December 20, 2024, holders of such shares would earn an aggregate profit of approximately
$11.7 million from the resale of such shares. The 350,000 shares of Common Stock issued to Pillsbury Winthrop Shaw Pittman LLC in consideration
for legal services provided to ACAB were issued at a value of $10.00 per share. The 600,000 shares of Common Stock issued to Cantor in
satisfaction of Cantor's deferred underwriting fee from the ACAB IPO were issued at a value of $10.00 per share. The 100,000 shares
of Common Stock issued to Roth Capital Partners, LLC for advisory services were issued at a value of $10.00 per share, the 32,852 shares
of Common Stock issued to Brookline Capital, in partial satisfaction of financial advisory fees were issued at a value of $10.00 per share,
the 360,000 shares of Common Stock issued to Polar Multi-Strategy Master Fund for satisfaction of a loan were issued at a value of $10.00,
and the 200,000 shares to J.V.B. Financial Group, LLC for advisory services were issued at a value of $10.00 per share. The 600,601 shares
of Common Stock issued to the Sponsor in satisfaction of a working capital note issued to ACAB for aggregate consideration of approximately
$2.0 million, were issued at a value of approximately $3.33 per share. The 600,000 shares of Common Stock issued to Mr. Chan, in satisfaction
of an approximately $2.0 million promissory note of Abpro Corporation were issued at a value of $3.33 per share. The 5,973,558 shares
of Common Stock that were originally issued as ACAB's Series B common stock that were subsequently converted into ACAB's Series
A common stock on April 18, 2023 were issued at a value of $0.0035 per share. The 50,000 shares of Common Stock issued to Apeiron
Investment Group Ltd. were issued at a value of $7.25 per share, and the 250,000 shares of Common Stock transferred from the Sponsor to
former directors of ACAB on October 25, 2021, was for no additional consideration. The of 9,498,900 shares of Common Stock issued as Merger
Consideration (defined below) to officers and directors of the Company were issued at a value of $10.00 per share.
The 50,000,000 shares of Common
Stock held by the Company Owners and registered herein were received as merger consideration shares in connection with the Business Combination
at approximately $10.00 per share and are subject to the 12-month lock-up restrictions described herein. The 13,850,000 shares of Common
Stock issuable upon exercise of the Placement Warrants will be issued at a price of $11.50 per share (the exercise price of the Placement
Warrants) and, therefore, based on the closing price of the Common Stock on December 20, 2024, such holders would not earn any profit
from the resale of such shares.
The unaudited pro forma financial information
included herein is not indicative of what our actual financial position or results of operations would have been.
The unaudited pro forma financial
information included herein is presented for illustrative purposes only and is not necessarily indicative of what our actual financial
position or results of operations would have been had the Business Combination been completed on the dates indicated.
There is no guarantee that the warrants
will ever be in the money; they may expire worthless or the terms of warrants may be amended.
The exercise price for the
warrants is $11.50 per ordinary share. There is no guarantee that the Public Warrants will ever be in the money prior to their expiration,
and as such, the warrants may expire worthless.
In addition, our warrants
were issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent,
and ACAB. The warrant agreement provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity
or correct any defective provision, but requires the approval by the holders of at least 50% of the then-outstanding Public Warrants to
make any change that adversely affects the interests of the registered holders of Public Warrants. Accordingly, we may amend the terms
of the Public Warrants in a manner adverse to a holder if holders of at least 50% of the then-outstanding Public Warrants approve of such
amendment. Although our ability to amend the terms of the Public Warrants with the consent of at least 50% of the then-outstanding Public
Warrants is unlimited, examples of such amendments could be amendments to, among other things, increase the exercise price of the warrants,
convert the warrants into cash or stock (at a ratio different than initially provided), shorten the exercise period or decrease the number
of shares of our Common Stock purchasable upon exercise of a warrant.
51
Our Warrant Agreement designates the courts
of the State of New York or the United States District Court for the Southern District of New York as the sole and exclusive
forum for certain types of actions and proceedings that may be initiated by holders of our warrants, which could limit the ability of
warrant holders to obtain a favorable judicial forum for disputes with us.
Our Warrant Agreement provides
that, subject to applicable law, (i) any action, proceeding or claim against Pono arising out of or relating in any way to the warrant
agreement, including under the Securities Act, will be brought and enforced in the courts of the State of New York or the United States
District Court for the Southern District of New York, and (ii) that we irrevocably submit to such jurisdiction, which jurisdiction
shall be the exclusive forum for any such action, proceeding or claim. We will waive any objection to such exclusive jurisdiction and
that such courts represent an inconvenient forum.
Notwithstanding the foregoing,
these provisions of the warrant agreement will not apply to suits brought to enforce any liability or duty created by the Exchange Act
or any other claim for which the federal district courts of the United States of America are the sole and exclusive forum. Any person
or entity purchasing or otherwise acquiring any interest in any of our warrants shall be deemed to have notice of and to have consented
to the forum provisions in our warrant agreement. If any action, the subject matter of which is within the scope the forum provisions
of the warrant agreement, is filed in a court other than a court of the State of New York or the United States District Court
for the Southern District of New York (a "foreign action") in the name of any holder of our warrants, such holder shall
be deemed to have consented to: (x) the personal jurisdiction of the state and federal courts located in the State of New York
in connection with any action brought in any such court to enforce the forum provisions (an "enforcement action"), and (y) having
service of process made upon such warrant holder in any such enforcement action by service upon such warrant holder's counsel in
the foreign action as agent for such warrant holder.
This choice-of-forum provision
may limit a warrant holder's ability to bring a claim in a judicial forum that we find favorable for disputes with us, which may
discourage such lawsuits. Alternatively, if a court were to find this provision of our warrant agreement inapplicable or unenforceable
with respect to one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving
such matters in other jurisdictions, which could materially and adversely affect our business, financial condition and results of operations
and result in a diversion of the time and resources of our management and Board.
We may redeem unexpired warrants prior to
their exercise at a time that is disadvantageous to warrantholders, thereby making their warrants worthless.
We have the ability to redeem
outstanding warrants at any time after they become exercisable and prior to their expiration, at a price of $0.01 per warrant, provided
that the last sales price of the Common Stock has been at least $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations,
recapitalizations and the like) for any 20 trading days within the 30 trading-day period ending on the third business day prior
to the date on which we give notice of such redemption and provided certain other conditions are met. Redemption of the outstanding warrants
could force warrantholders (i) to exercise their warrants and pay the exercise price therefor at a time when it may be disadvantageous
for them to do so, (ii) to sell their warrants at the then-current market price when they might otherwise wish to hold their warrants
or (iii) to accept the nominal redemption price which, at the time the outstanding warrants are called for redemption, is likely
to be substantially less than the market value of their warrants. None of the Placement Warrants will be redeemable by us so long as they
are held by the Sponsor or its permitted transferees.
There may be sales of a substantial amount
of our Common Stock after the Business Combination by current stockholders, and these sales could cause the price of our Common Stock
to fall.
Future sales of the Common
Stock may cause the market price of its securities to drop significantly, even if its business is doing well.
ACAB entered into a registration
rights agreement in connection with the IPO, pursuant to which the holders of Founder Shares, Placement Warrants and any units the Sponsor
or ACAB's officers, directors or their affiliates may be issued in payment of working capital loans made to ACAB (and all underlying
securities), are entitled to registration rights pursuant to a Registration Rights Agreement dated January 13, 2022, by and among ACAB,
the Sponsor and certain other securityholders of ACAB. The holders of a majority of these securities are entitled to make up to three
demands that we register such securities. The holders of a majority of the units issued in payment of working capital loans made to us
(or underlying securities) can elect to exercise these registration rights at any time. In addition, the holders have certain "piggy-back"
registration rights. We will bear the expenses incurred in connection with the filing of any such registration statements.
52
Upon the effectiveness of
this registration statement we are filing pursuant to the registration rights agreement, these parties may sell large amounts of our Common
Stock in the open market or in privately negotiated transactions, which could have the effect of increasing the volatility in our Common
Stock share price or putting significant downward pressure on the price of our Common Stock.
Sales of substantial amounts
of our Common Stock in the public, or the perception that such sales will occur, could adversely affect the market price of our Common
Stock and make it difficult for us to raise funds through securities offerings in the future.
Future resales of our Common Stock may cause
the market price of our securities to drop significantly, even if our business is doing well.
In connection with the Business
Combination, pursuant to the Abpro Lock-Up Agreements, certain Abpro stockholders agreed that they will not, during the period
beginning at the immediately prior to the Closing (the "Effective Time") and continuing to and including the date that is
one (1) year after the date of the Effective Time, subject to earlier release conditions, directly or indirectly, offer, sell, contract
to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any shares of Common Stock, or any options
or warrants to purchase any shares of Common Stock, or any securities convertible into, exchangeable for or that represent the right to
receive shares of Common Stock, or any interest in any of the foregoing (in each case, subject to certain exceptions set forth in the
Abpro Lock-Up Agreements). However, the 600,601 Additional Sponsor Shares issued to the Sponsor at closing pursuant to Amendment
No. 1 to the Business Combination Agreement are not subject to the Abpro Lock-Up Agreements.
The Sponsor is subject to
a lock-up pursuant to a letter agreement, entered into at the time of the IPO, among ACAB, the Sponsor and the other parties thereto,
pursuant to which the Sponsor is subject to a lock-up beginning on the Closing and end the earliest of: (a) 12-months from the Closing,
(b) the date we consummate a liquidation, merger, share exchange or other similar transaction with an unaffiliated third party that
results in all of our shareholders having the right to exchange their Common Stock for cash, securities or other property and (c) the
date on which the closing sale price of our Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends,
reorganizations and recapitalizations and the like) for any twenty (20) trading days within any thirty (30) trading day period
commencing at least one hundred and fifty (150) days after the Closing.
However, following the expiration
of such lock-ups, the Sponsor and the holders of Lock-Up Shares will not be restricted from selling our Common Stock held by them, other
than by applicable securities laws. As such, sales of a substantial number of Common Stock in the public market could occur at any time.
These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market
price of our Common Stock.
The shares held by Sponsor
and the Lock-Up Shareholders may be sold after the expiration of their applicable lock-up periods. As restrictions on resale end and registration
statements are available for use, the sale or possibility of sale of these shares could have the effect of increasing the volatility in
our Common Stock share price or the market price of our Common Stock could decline if the holders of currently restricted shares sell
them or are perceived by the market as intending to sell them.
Our Warrants may not be exercised at all
or may be exercised on a cashless basis and we may not receive any cash proceeds from the exercise of the Warrants.
The exercise price of the
Warrants may be higher than the prevailing market price of the underlying Common Stock. The exercise price of the Warrants is subject
to market conditions and may not be advantageous if the prevailing market price of the underlying Common Stock is lower than the exercise
price. The cash proceeds associated with the exercise of Warrants to purchase our Common Stock are contingent upon our stock price. The
value of our Common Stock will fluctuate and may not align with the exercise price of the warrants at any given time. If the Warrants
are "out of the money," meaning the exercise price is higher than the market price of our common stock, there is a high likelihood
that Warrant holders may choose not to exercise their Warrants. As a result, we may not receive any proceeds from the exercise of the
Warrants.
53
Furthermore, with regard to
the Warrants, it is possible that we may not receive cash upon their exercise since the Warrants may be exercised on a cashless basis.
A cashless exercise allows warrant holders to convert the warrants into shares of our Common Stock without the need for a cash payment.
Instead of paying cash upon exercise, the Warrant holder would receive a reduced number of shares based on a predetermined formula. As
a result, the number of shares issued through a cashless exercise will be lower than if the Warrants were exercised on a cash basis, which
could impact the cash proceeds we receive from the exercise of such warrants.
The Warrants may only be exercised
for cash provided there is then an effective registration statement registering the Common Stock issuable upon the exercise of such Warrants.
If there is not a then-effective registration statement, then such warrants may be exercised on a "cashless basis," pursuant
to an available exemption from registration under the Securities Act.
We may from time to time need additional
financing to fund operations and to expand our business, including to pursue acquisitions and other strategic opportunities.
As a result of the Business
Combination, we received net proceeds of approximately $2.3 million, net of transaction costs related to the Business Combination of approximately
$7.1 million.
We intend to fund our current
working capital needs in the ordinary course of business and to continue to expand our business with our existing cash and cash equivalents,
and cash flows from operating activities. However, we may from time to time need additional financing to fund operations and to expand
our business. We may, from time to time, explore additional financing sources to lower our cost of capital, which could include equity,
equity-linked and debt financing. In addition, from time to time, we may evaluate acquisitions and other strategic opportunities. If we
elect to pursue any such investments, we may fund them with internally generated funds, bank financing, the issuance of other debt or
equity or a combination thereof. There is no assurance that any such financing or funding would be available to us on acceptable terms
or at all. Sales of securities registered under the registration statement to which this prospectus forms a part could lower the market
price of our Common Stock and warrants. We do not believe this would harm our chances of raising capital, but could affect the sale price
and number of securities we need to issue.
There is no assurance that
the holders of the Warrants will elect to exercise any or all of the Warrants, which could impact our liquidity position. To the extent
that the Warrants are exercised on a "cashless basis," the amount of cash we would receive from the exercise of the Warrants
will decrease. We believe the likelihood that Warrant holders will exercise their Warrants, and therefore the amount of cash proceeds
that we would receive is, among other things, dependent upon the market price of our Common Stock. If the market price for our Common
Stock is less than the applicable exercise price of $11.50, subject to adjustment as described herein, we believe such holders will be
unlikely to exercise their Warrants.
54
USE OF PROCEEDS
All of the securities offered
by the Selling Securityholders pursuant to this prospectus will be sold by the Selling Securityholders for their respective accounts.
The Company will not receive any of the proceeds from these sales.
The Company will receive up
to an aggregate of approximately $331.8 million from the exercise of the Warrants, assuming the exercise in full of all of the
Warrants for cash. The Company expects to use the net proceeds from the exercise such warrants for other general corporate purposes. There
is no assurance that the holders of the Warrants will elect to exercise any or all of such warrants. To the extent that warrants are exercised
on a "cashless basis," the amount of cash we would receive from the exercise of such warrants will decrease. See "
Description
of Capital Stock
" for additional information regarding the warrants.
There is no assurance that
the holders of the Warrants will elect to exercise any or all of the Warrants, which could impact our liquidity position. We believe the
likelihood that Warrant holders will exercise their Warrants, and therefore the amount of cash proceeds that we would receive is, among
other things, dependent upon the market price of our Common Stock. If the market price for our Common Stock is less than the applicable
exercise price of $11.50, subject to adjustment as described herein, we believe such holders will be unlikely to exercise their Warrants.
The Selling Securityholders
will pay any underwriting fees, discounts and selling commissions incurred by such Selling Securityholders in disposing of their Common
Stock. Pursuant to the Registration Rights Agreement, the Company will bear all other costs, fees and expenses incurred in effecting
the registration of the Common Stock covered by this prospectus, including, without limitation, all registration and filing fees, Nasdaq
listing fees and fees and expenses of counsel and independent registered public accountants.

Description of the Business Combination
On November 12, 2024, ACAB
and Abpro completed a series of transactions that resulted in the combination (the "Closing" of the "Business Combination")
of ACAB with Abpro Corporation, a Delaware corporation ("Abpro Corporation"), pursuant to the previously announced Business
Combination Agreement, dated December 11, 2023, amended by an amendment dated September 4, 2024 (the "BCA"), by and among
ACAB, Abpro Merger Sub Corp., a Delaware corporation and a wholly owned subsidiary of ACAB ("Merger Sub"), and Abpro Corporation,
following the approval at the special meeting of the shareholders of ACAB held on November 7, 2024 (the "Special Meeting").
On November 12, 2024, pursuant to the BCA, and as described in greater detail in the Company's final prospectus and definitive proxy
statement, which was filed with the U.S. Securities and Exchange Commission (the "SEC") on October 18, 2024 (the "Proxy
Statement/Prospectus"), Merger Sub merged with and into Abpro Corporation, with Abpro Corporation surviving the merger as a wholly
owned subsidiary of ACAB, and ACAB changed its name to Abpro Holdings, Inc. ("New Abpro"). As consideration for the Business
Combination, New Abpro issued to or reserved for Abpro Corporation shareholders an aggregate of approximately 50,000,000 shares of New
Abpro common stock, par value $0.0001 per share (the "Common Stock"), consisting of 39,123,200 shares of Common Stock issued
to Abpro Corporation shareholders, and 10,872,400 shares of Common Stock reserved for issuance in connection with certain Abpro Corporation
rollover RSUs and stock options (collectively, the "Merger Consideration"). In addition, New Abpro issued an aggregate of
3,367,401 shares of Common Stock to the PIPE investors (as described below), an aggregate of 1,282,852 shares of Common Stock to vendors
in connection with the Closing, and Atlantic Coastal Acquisition Management II LLC (the "Sponsor") forfeited and New Abpro
cancelled 966,442 shares of Common Stock (further described below).
Under the Second Amended Articles
of Incorporation of ACAB dated November 12, 2024, each of the outstanding shares of ACAB Series A Common Stock and the outstanding share
of ACAB Class B Common Stock was exchanged into one share of Common Stock.
Abpro's 61,099 outstanding
common stock warrants expired upon the consummation of the Business Combination.
In connection with the Special
Meeting, ACAB shareholders holding 330,276 shares of ACAB's Series A common stock (the "Public Shares") (after giving
effect to the share repurchases by Yorkville as described below) exercised their right to redeem their shares for a pro rata portion of
the funds in ACAB's trust account (the "Trust Account"). Prior to the Closing approximately $3,752,627 (approximately
$11.36 per Public Share) was removed from the Trust Account to pay such holders.
Following the Closing, Abpro's
stockholders shall be issued up to 14,500,000 additional shares of the Post- Combination Company common stock ("Earnout Shares")
if, within five calendar years after the closing of the Business Combination, the volume weighted average price of shares of Series A
Common Stock on Nasdaq, or any other national securities exchange on which the shares of Series A Common Stock are then traded ("VWAP")
meets or exceeds three-tier target prices defined in the agreement, as follows:
a) one-third of the total
Earnout Shares, if, the VWAP is greater than or equal to $13.00 over any 20 trading days within any consecutive 30 trading day period
(the "First Share Target")
57
b) one-third of the total
Earnout Shares, if, the VWAP is greater than or equal to $15.00 over any 20 trading days within any consecutive 30 trading day period
(the "Second Share Target")
c) one-third of the total
Earnout Shares, if, the VWAP is greater than or equal to $18.00 over any 20 trading days within any consecutive 30 trading day period
(the "Third Share Target").
If following the Closing,
a Change of Control (as defined in the Business Combination Agreement) occurs on or before the five year anniversary of the Closing Date,
then if (i) the per share value of the consideration to be received by stockholders in connection with the Change of Control exceeds $13.00
per share and the First Share Target has not been previously achieved, then the First Share Target will be deemed to have been achieved,
(ii) the per share value of the consideration to be received by stockholders exceeds $15.00 per share and the Second Share Target has
not been previously achieved, then the Second Share Target will be deemed to have been achieved, and (iii) the per share value of the
consideration to be received by stockholders exceeds $18.00 per share and the Third Share Target has not been previously achieved, then
the Third Share Target will be deemed to have been achieved. Any Contingency Consideration that is not deemed to be earned in connection
with the Change of Control shall be forfeited by the stockholders for no consideration.
These shares are contingently
issuable upon the achievement of the set market performance targets. Considering the underlying contingent consideration to be transferred
are common stocks, and as such is indexed to the Post-Combination Company's own stock and classified in stockholders' equity
in the statement of financial position, we deemed the contingent payments under the earnout provisions to qualify for the scope exception
in Accounting Standards Codification ("ASC") 815-10-15-74(a). As a result, the contingent consideration obligation will be
recognized when the contingency is resolved, and the consideration is paid or becomes payable and has no impact on the pro forma condensed
financial statements.
Concurrently with the execution
of the BCA, Abpro and Abpro Bio International, Inc. ("Abpro Bio"), an Abpro stockholder, entered into an agreement (the "Sponsor
Share Letter"), pursuant to which Sponsor agreed to, at the Closing Date, (i) retain 2,950,000 shares of Series A Common Stock of
ACAB, (ii) retain 291,667 shares, and transfer 983,333 shares to Abpro and 983,333 of the shares Abpro Bio ("Promote Shares"),
for such parties to use to obtain non-redemption commitments from SPAC stockholders or other capital for SPAC or the Surviving Corporation
(with any shares unused for such purpose to be retained by such party), and (iii) forfeit the remainder of any Series A Common Stock and
Series B Common Stock held by Sponsor (or 966,441 Series A shares and 1 Series B shares). It was also agreed in the Sponsor Share Letter
that the Sponsor will transfer 200,000 shares to one of ACAB's financial advisors for the services provided prior to the merger
date. The transfer of 983,333 shares of ACAB Series A Common Stock to Abpro Bio was reflected in the pro forma condensed financial statements
as a part of the recapitalization in conjunction with the Business Combination and this transfer has no financial impact. As it relates
to 983,333 shares transferred to Abpro, the corresponding issuance costs will be recorded at the date these shares are transferred to
third-party investors against non-redemption or capital commitments. If the 983,333 shares of Series A common stock held by Abpro and
291,667 shares held by the Sponsor are transferred to third-party investors in conjunction with their capital commitments, the maximum
related costs to be recorded to additional paid-in capital will be in the amount of approximately $14.3 million (based on the fair value
of the ACAB's common stock shares of $11.20 per share at September 30, 2024) with the corresponding decrease in the paid-in-capital.
Under the terms of the BCA,
at the Closing of the Business Combination, the Sponsor received 600,601 shares of common stock of New Abpro in exchange for the extinguishment
of $2,000,000 advances to ACAB by the Sponsor.
Other Related Events in Connection with the
Business Combination
Other related events that
took place in connection with the Business Combination are summarized below:
●
In connection with the Closing, the PIPE Investors (defined below) received 3,367,401 shares of New Abpro under the PIPE Subscription Agreements (defined below). On August 22, 2024, ACAB entered into subscription agreements with Abpro Bio and Celltrion Inc. ("Celltrion" and together with Abpro Bio, the "PIPE Investors") (the "PIPE Subscription Agreements"). Pursuant to the PIPE Subscription Agreements, at the Closing of the Business Combination, Abpro Bio purchased 622,467 newly-issued shares of New Abpro at a price of $10.00 per share, for an aggregate purchase price of $6,225,670 of which $4,225,663 was through the extinguishment of the balance due to Abpro Bio under the promissory note agreement between Abpro and Abpro Bio, and the remainder of $2,000,007 in cash. In addition, Abpro Bio received an aggregate of 1,244,934 Company Incentive Shares. Celltrion purchased 500,000 newly issued shares of New Abpro common stock, at the closing of the Business Combination, at a price of $10.00 per share, for an aggregate purchase price of $5,000,000. In addition, Celltrion was granted an aggregate of 1,000,000 Company Incentive Shares.
58
●
On November 7, 2024, ACAB and Abpro entered into a Confirmation of
an OTC Equity Prepaid Forward Transaction (the "Forward Purchase Agreement") with YA II PN, LTD ("Yorkville").
In connection with the Closing, and pursuant to the terms of the Forward Purchase Agreement, prior to the Closing Date, Yorkville purchased
100,000 shares from third parties ("Recycled Shares"), pursuant to the pricing date notice dated November 12, 2024. At the
Closing of the Business Combination, in accordance with the terms of the Forward Purchase Agreement, Yorkville received approximately
$1.1 million (the "Prepayment Amount") from the Trust Account, equal to $11.36 per Recycled Share (the "Initial Price").
●
In connection with the Closing, approximately $2 million of promissory note liabilities of Abpro were converted into 600,000 New Abpro common stock shares.
Accounting for the Business Combination
Notwithstanding the legal
form of the Business Combination pursuant to the Business Combination Agreement, the Business Combination is accounted for as a reverse
recapitalization in accordance with US GAAP. Under this method of accounting, ACAB is treated as the acquired company and Abpro is treated
as the acquirer for financial reporting purposes. Accordingly, for accounting purposes, the financial statements of the Post-Combination
Company represent a continuation of the financial statements of Abpro, with the Business Combination treated as the equivalent of Abpro
issuing stock for the net assets of ACAB, accompanied by a recapitalization. The net assets of ACAB are stated at historical cost, with
no goodwill or other intangible assets recorded. Operations prior to the Business Combination are those of Abpro. Abpro has been determined
to be the accounting acquirer based on an evaluation of the following facts and circumstances:
●
the Post-Combination Company Board consists of five directors, four of whom were designated by Abpro and one of whom were designated by ACAB;
●
Abpro's existing senior management team comprises the senior management of the Combined Company; and
●
Abpro's operations prior to the Business Combination comprise the ongoing operations of the Post-Combination Company as ACAB had minimal operations pre-combination.
Basis of Pro Forma Presentation
The unaudited pro forma condensed
combined financial information has been prepared in accordance with Article 11 of Regulation S-X. The adjustments in the unaudited pro
forma condensed combined financial information have been identified and presented to provide relevant information necessary for an illustrative
understanding of the Post-Combination Company upon consummation of the Business Combination in accordance with GAAP.
Assumptions and estimates
underlying the unaudited pro forma adjustments set forth in the unaudited pro forma condensed combined financial information are described
in the accompanying notes. The unaudited pro forma condensed combined financial information has been presented for illustrative purposes
only and is not necessarily indicative of the operating results and financial position that would have been achieved had the Business
Combination occurred on the dates indicated, and does not reflect adjustments for any anticipated synergies, operating efficiencies, tax
savings or cost savings. Any cash proceeds remaining after the consummation of the Business Combination and the other events contemplated
by the Business Combination Agreement are expected to be used for general corporate purposes. Further, the unaudited pro forma condensed
combined financial information does not purport to project the future operating results or financial position of the Post-Combination
Company following the consummation of the Business Combination. The unaudited pro forma adjustments represent management's estimates
based on information available as of the date of these unaudited pro forma condensed combined financial information and are subject to
change as additional information becomes available and analyses are performed. ACAB and Abpro have not had any historical relationship
prior to the transactions discussed in this proxy statement/prospectus. Accordingly, no pro forma adjustments were required to eliminate
activities between the companies.

The shares held by the ACAB
Initial Stockholders include 7,200,000 Series A common stock shares held by ACAB's sponsor, 300,000 Series A common stock shares
which have been transferred to ACAB's directors and Apeiron, and 600,601 Series A common stock shares issued to the Sponsor in extinguishment
of $2,000,000 advances by the Sponsor to ACAB. The one share of Series B common stock held by ACAB's sponsor was reduced to zero,
due to the share's forfeiture under the terms of the Sponsor Share Letter. The Series A common stock shares held by ACAB's
sponsor of 7,200,000 were reduced by 966,441 forfeited shares, 983,333 shares transferred to ABI, 983,333 shares transferred to Abpro,
and 200,000 shares transferred to one of ACAB's financial advisors under the terms of the Sponsor Share Letter. As it relates to
983,333 shares transferred to Abpro, the corresponding shares were excluded from the shares outstanding since these shares are held by
New Abpro. The 983,333 shares held by Abpro will be included in the shares outstanding on the date these shares are transferred to third-party
investors against non-redemption or capital commitments. In addition, on April 4, 2023, ACAB and the Sponsor entered into agreements with
several unaffiliated third parties in exchange for them agreeing not to redeem certain public shares of ACAB at the special meeting called
by the Company (the "Meeting") to approve an extension of time for the Company to consummate an initial business combination
(the "Charter Amendment Proposal"). In exchange for the foregoing commitments not to redeem such shares, the Sponsor has agreed
to transfer to such investors an aggregate of 825,225 shares of ACAB held by the Sponsor immediately following consummation of an initial
business combination if they continued to hold such Non-Redeemed Shares through the Meeting. As such, at the Closing Date of the Business
Combination, 825,225 shares held by the Sponsor were transferred to the investors. Also, on April 10, 2024, the Sponsor entered into
a subscription agreement with Polar Multi-Strategy Master Fund ("Polar"), pursuant to which Polar provided the capital contribution
to the Sponsor in the amount of $360,000 in exchange for 1 share of the Company's Series A common stock held by the
Sponsor for each $1 invested by the Investor as of the closing of the Merger. As such, at the Closing Date of the Business Combination,
360,000 shares held by the Sponsor were forfeited and the corresponding number of New Abpro common stock shares were issued to Polar.
Following the Closing, the
Abpro stockholders will have the right to receive the Contingent Consideration upon the occurrence of certain triggering events. Because
the Contingent Consideration is contingently issuable based upon the price of Post- Combination Company common stock reaching certain
thresholds that have not yet been achieved, the pro forma Post-Combination Company common stock issued and outstanding immediately after
the Business Combination excludes the Contingent Consideration.
The following table summarizes
the total New Abpro shares issuable to Abpro in connection with the Business Combination.

Company equity with an aggregate value equal to approximately $500 million, comprised of (i) 39,123,200 shares of Post-Combination Company
common stock, (ii) 10,872,400 shares of Post-Combination Company common stock issuable upon the exercise of options and vesting of restricted
stock units, and (iii) 14,500,000 shares of Post-Combination Company common stock issuable upon the Earnout provisions if and when achieved,
each multiplied by the deemed value of $10.00 per share.

Transaction Accounting Adjustments to Unaudited
Pro Forma Condensed Combined Balance Sheet as of September 30, 2024
The transaction accounting
adjustments included in the unaudited pro forma condensed combined balance sheet as of September 30, 2024 are as follows:
(1)
Reflects the liquidation
    and reclassification of cash and marketable securities held in the Trust Account that becomes available for general use by the
    Post-Combination Company following the Business Combination. In addition, in connection with the special meeting of stockholders of
    ACAB on November 7, 2024 related to the approval of the Merger, stockholders holding 330,276 shares of ACAB Series A Common Stock
    (net of 100,000 shares repurchased by Yorkville, as discussed below) issued in the Initial Public Offering of ACAB exercised their
    right to redeem their shares for a pro rata portion of the funds in the Trust Account. Pursuant to the terms of the Forward Purchase
    Agreement, prior to the closing of the Business Combination, Yorkville repurchased 100,000 Series A Common Stock shares from holders
    that previously elected to redeem their shares during the redemption period ("Recycled Shares"). As a result,
    approximately $3.8 million (approximately $11.36 per share) was removed from the Trust Account to pay such holders.
(2)
Reflects the transfer of ACAB's Series A Common Stock subject to possible redemptions as of September 30, 2024 to permanent equity.
(3)
Reflects the consideration of approximately $6.4 million from the common stock shares issued under the PIPE Subscription Agreements, net of $4.2 million settlement of the balance due to ABI under Abpro's promissory note agreement and $0.6 million of issuance costs.
(4)
Reflects the exchange of all Abpro preferred stock (Series A preferred, Series B preferred, and Series C preferred, Series D preferred, Series E preferred, Series F preferred) into Post-Combination Company Common stock pursuant to the conversion rate for such shares of Abpro preferred stock effective immediately prior to the Closing.
(5)
Reflects the preliminary estimated payment of direct and incremental transaction costs incurred prior to or concurrent with the Business Combination of approximately $4.2 million (exclusive of the deferred underwriters' discount discussed below) which were to be cash settled upon the Closing in accordance with the Business Combination Agreement. Transaction costs include legal, accounting, financial advisory and other professional fees related to the Business Combination. Of the total cash transaction costs of approximately $4.2 million, approximately $2.4 million are expected to be incurred by Abpro and charged to additional paid-in capital and approximately $1.8 million are to be incurred by ACAB and charged to expenses through accumulated deficit.
(6)
Reflects the settlement
    of $10.5 million deferred payable settled through issuance of 600,000 shares to Cantor, cash payment of $210,000 and forgiveness
    of the remaining balance. The fair value of the shares was $6.7 million (based on the market value of $11.20 per share as of September 30,
    2024) and the excess of $3,570,000 is accounted for as the recovery of accumulated deficit (since the initial accretion to the mezzanine
    reduced the accumulated deficit). For more information regarding the Cantor deferred underwriting fees, see
"Certain Relationships
    and Related Party Transactions—ACAB — Deferred Underwriting Fee."
(7)
Reflects the recapitalization of Abpro equity as a result of the exchange of Abpro common stock for the Post-Combination Company Common Stock and the exchange of Series A common stock and Series B common stock of ACAB into common stock shares.
(8)
Reflects the elimination of ACAB's accumulated deficit to additional paid-in capital.
(9)
Represents approximately $7.6 million of non-cash transaction costs attributable to the payments in 350,000 shares of the Post-combination Company's common stock shares for legal services, 232,852 shares of common stock shares for financial advisory fees, and 100,000 shares of Series A common stock shares for capital advisory services rendered to ACAB in connection with the Merger and payable upon the consummation of the Merger (based on the market value of $11.20 per share as of September 30, 2024).
(10)
Reflects the issuance of 600,601 of the Post-combination Company's common stock shares to the Sponsor in exchange for the extinguishment of $2.0 million of the working capital note provided by the Sponsor.
(11)
Reflects repayment of $2.1 million in related party loan liabilities outstanding at September 30, 2024, including approximately $2 million in related party loans with an Abpro executive settled through the issuance of 600,000 shares at Closing, and $0.1 million in cash.
(12)
Reflect the Prepayment Amount to Yorkville and the fair value of the Forward Purchase Agreement asset. Pursuant to the terms of the Forward Purchase Agreement, on the Closing Date, Yorkville received approximately $1.1 million Prepayment Amount equal to $11.36 per Recycled Share (the "Initial Price"). Based on information available as of the date of this prospectus, certain assumptions, and preliminary accounting analyses that management believes are reasonable under the circumstances, the Forward Purchase Agreement is expected to be accounted for at fair value and result in an asset at the Closing Date. The actual adjustments may materially differ from the pro forma adjustments that appear in this prospectus. The fair value of the combined Company's position under the Forward Purchase Agreement was calculated using the Monte Carlo simulation, based on the following assumptions: The Company's stock price of $11.20 per share as of September 30, 2024, the risk-free rate of 4.73%, the term of three months, and the expected volatility of 100%. The net asset arising from the Forward Purchase Agreement totaled $940,000. The difference between the fair value of the Forward Purchase Agreement asset of $940,000 and the prepayment amount of $1,134,000 was expensed at the Closing Date.
(13)
Reflects the redemption of ACAB Series A Common Stock shares in connection with the special meeting of stockholders of ACAB on September 19, 2024, when the stockholders holding 126,122 shares of ACAB Series A Common Stock issued in the Initial Public Offering of ACAB exercised their right to redeem their shares for a pro rata portion of the funds in the Trust Account. As a result, this adjustment reflects approximately $1.4 million (approximately $11.27 per share after removal of interest available to pay taxes) payment to the redeeming shareholders in October 2024.
(14)
Reflects the elimination of ACAB's receivable and Abpro's payable related to intercompany advances.

follows:
(1)
Reflects an adjustment to eliminate interest income related to the Trust Account, including elimination of the related income tax expenses.

This adjustment is non-recurring in nature and is not expected to have a continuing effect on future period statements of operations.

Notes to Unaudited Pro Forma Condensed Combined
Financial Statements
1. Basis of Presentation
The Business Combination is
accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, ACAB is treated as the "acquired"
company for financial reporting purposes. Accordingly, for accounting purposes, the financial statements of the Post-Combination Company
represent a continuation of the financial statements of Abpro, and the Business Combination is treated as the equivalent of Abpro issuing
stock for the net assets of ACAB, accompanied by a recapitalization. The net assets of ACAB are stated at historical cost, with no goodwill
or other intangible assets recorded. Operations prior to the Business Combination are those of Abpro.
The unaudited pro forma condensed
combined balance sheet as of September 30, 2024, combines the historical balance sheet of ACAB as of September 30, 2024, and the historical
balance sheet of Abpro as of September 30, 2024, on a pro forma basis as if the Business Combination and the other related events in connection
with the Business Combination Agreement had been consummated on September 30, 2024. The unaudited pro forma condensed combined statement
of operations for the nine months ended September 30, 2024, combines the historical statements of operations of ACAB for the nine months
ended September 30, 2024, and the historical statements of operations of Abpro for the nine months ended September 30, 2024 on a pro forma
basis as if the Business Combination, the other events contemplated by the Business Combination Agreement and the other related events
in connection with the Business Combination had been consummated on January 1, 2023, the beginning of the earliest period presented. The
unaudited pro forma condensed combined statement of operations for the year ended December 31, 2023, combines the historical statements
of operations of ACAB for the year ended December 31, 2023, and the historical statements of operations of Abpro for the year ended December
31, 2023 on a pro forma basis as if the Business Combination and other related events in connection with the Business Combination had
been consummated on January 1, 2023, the beginning of the earliest period presented.
The unaudited pro forma condensed
combined financial information and accompanying notes have been derived from and should be read in conjunction with:
●
the historical unaudited condensed consolidated financial statements of ACAB as of and for the three and nine months ended September 30, 2024, and the related notes, which are included in ACAB's Quarterly Report on Form 10-Q filed with the SEC on November 26, 2024 (the "ACAB 10-Q");
●
the historical audited consolidated financial statements of ACAB as of and for the year ended December 31, 2023, and the related notes, which are included in ACAB's Annual Report on Form 10-K/A filed with the SEC on April 1, 2024 (the "ACAB 10-K/A");
65
●
the historical unaudited condensed consolidated financial statements of Abpro as of and for the nine months ended September 30, 2024, and the related notes included in this prospectus; and
●
the Post-Combination Company Board consists of five directors, four of whom were designated by Abpro and one of whom were designated by ACAB;
●
Abpro's existing senior management team comprises the senior management of the Combined Company;
●
the historical audited consolidated financial statements of Abpro as of and for the year ended December 31, 2023, and the related notes; and
●
other information relating to ACAB and Abpro contained in this Prospectus, including the Business Combination Agreement and the description of certain terms thereof.
The unaudited pro forma condensed
combined financial information should also be read together with the sections of the ACAB 10-K/A and the ACAB 10-Q entitled "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and the section of this Prospectus entitled "Management's
Discussion and Analysis of Financial Condition and Results of Operations," as well as other financial information included elsewhere
in this Prospectus.
Management has made significant
estimates and assumptions in its determination of the pro forma adjustments. As the unaudited pro forma condensed combined financial information
has been prepared based on these preliminary estimates, the final amounts recorded may differ materially from the information presented.
The pro forma adjustments
are based on information available as of the date of this proxy statement/prospectus and certain assumptions and methodologies that management
believes are reasonable under the circumstances. The unaudited condensed pro forma adjustments, which are described in these notes, may
be revised as additional information becomes available and is evaluated. Therefore, the actual adjustments may materially differ from
the pro forma adjustments that appear in this proxy statement/prospectus. Management considers this basis of presentation to be reasonable
under the circumstances.
One-time direct and incremental
transaction costs anticipated to be incurred by Abpro prior to, or concurrent with, the Closing are reflected in the unaudited pro forma
condensed combined balance sheet as a direct reduction to the Post-Combination Company's additional paid-in capital. Since the Business
Combination is expected to be accounted for as a reverse merger and recapitalization of Abpro into ACAB, the costs incurred by ACAB to
consummate the merger are expensed as incurred.
2. Transaction Accounting Adjustments to Unaudited
Pro Forma Condensed Combined Financial Information
The unaudited pro forma condensed
combined financial information has been prepared in accordance with Article 11 of Regulation S-X. The adjustments in the unaudited pro
forma condensed combined financial information have been identified and presented to provide relevant information necessary for an illustrative
understanding of Abpro upon consummation of the Business Combination in accordance with GAAP. Assumptions and estimates underlying the
unaudited pro forma adjustments set forth in the unaudited pro forma condensed combined financial information are described in the accompanying
notes to the pro forma schedules.
66
3. Loss per Share
Represents the net loss per
share calculated using the historical shares of ACAB Common Stock outstanding, and the issuance of additional shares in connection with
the Business Combination and other related events, assuming all shares were outstanding since January 1, 2023. As the Business Combination
and other related events are being reflected as if they had occurred at the beginning of the period presented, the calculation of weighted
average shares outstanding for basic and diluted net loss per share assumes that the shares issuable in connection with the Business Combination
have been outstanding for the entire period presented. The stock options, restricted stock units and warrants were excluded in the earnings
per share calculation as they would be anti-dilutive.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF NEW ABPRO
The following
discussion and analysis summarizes the significant factors affecting the consolidated operating results, financial condition, liquidity,
and cash flows of our company as of and for the periods presented below. The following discussion and analysis of our financial condition
and results of operations should be read together with our consolidated financial statements and the related notes and other financial

available to, our management. Actual results and timing of selected events could differ materially from those discussed or implied by
the forward-looking statements as a result of various factors, including those discussed below and detailed elsewhere in this proxy statement/prospectus,
particularly in the sections entitled "Risk Factors" and "Forward-Looking Statements; Summary Risk Factors; Market,
Ranking and Other Industry Data."
Unless otherwise indicated
or the context otherwise requires, references in this section to "Abpro," "we," "us," "our,"
"the Company," and other similar terms refer to Abpro Corporation and its subsidiaries prior to the Business Combination and
to Abpro Holdings, Inc. following the consummation of the Business Combination on November 13, 2024.
Overview
We are a biotechnology company
dedicated to developing next-generation antibody therapeutics with the goal of improving the lives of patients with severe and life-threatening
diseases. We are focused on novel antibody constructs for immuno-oncology and ophthalmology. By leveraging our proprietary DiversImmune®
and MultiMabTM antibody discovery and engineering platforms, we are developing a pipeline of antibodies, both independently and through
collaborations with global pharmaceutical and research institutions.
Our two lead product candidates,
ABP-102 and ABP-201, feature our next generation tetravalent antibody format, or TetraBi antibody format, which binds to two different
targets with two distinct binding sites per target. ABP-102 is designed to redirect a patient's immune system to fight cancer by
engaging T cells through co-targeting human epidermal growth factor receptor 2, or HER2, and cluster of differentiation 3, or CD3, T-cell
co-receptor. We plan initially to develop ABP-102 for difficult to treat HER2+ solid tumors, focusing on orphan indications. ABP-201 is
designed to block blood vessel formation and normalize damaged vessels through co-targeting vascular endothelial growth factor, or VEGF,
and angiopoietin-2, or ANG-2. We plan to develop ABP-201 to treat vascular disease of the eye, focusing on wet age-related macular degeneration
(Wet AMD). We intend to follow these two lead product candidates with a broad pipeline of CD3-targeting T-cell engagers based on the differentiated
format of ABP-102. We expect to initiate clinical trials for ABP-102 and ABP-201 in 2026.
69
Recent Developments
On November 13, 2024 (the
"Closing Date"), we consummated a business combination pursuant to the terms of the Business Combination Agreement, dated
as of December 11, 2023 (the "Business Combination Agreement") by and among the Company, Atlantic Coastal Acquisition Corp.
II, a Delaware corporation ("ACAB") and Abpro Merger Sub Corp., a Delaware corporation ("Merger Sub"). Pursuant
to the Business Combination Agreement, on the Closing Date, (i) ACAB changed its name to "Abpro Holdings, Inc.," and (ii) Merger
Sub merged with and into the Company, with the Company as the surviving company in the Business Combination. After giving effect to the
Business Combination, the Company became a wholly owned subsidiary of ACAB.
Impact of Macroeconomic Events
Economic uncertainty in various
global markets caused by political instability and conflicts, such as the ongoing conflicts in the Ukraine, and Israel, and economic challenges
have led to market disruptions, including significant volatility in commodity prices, credit and capital market instability and supply
chain interruptions, which have caused record inflation globally. Our business, financial condition, and results of operations could be
materially and adversely affected by further negative impacts on the global economy and capital markets resulting from these global economic
conditions, particularly if such conditions are prolonged or worsen. Although, to date, our results of operations have not been materially
impacted by these global economic and geopolitical conditions, it is impossible to predict the extent to which our operations may be impacted
in the short and long term. The extent and duration of these market disruptions, whether as a result of the military conflict between
Russia and Ukraine, the effects of the Russian sanctions, the conflict between Israel and Hamas, geopolitical tensions, record inflation,
or otherwise, are impossible to predict. Any such disruptions may also magnify the impact of other risks described or incorporated by
reference in this prospectus.

Revenue
We did not generate any material
collaboration or royalty revenue during the nine months ended September 30, 2024 and 2023. Our research and development services revenue
increased by $0.2 million during the nine months ended September 30, 2024 as compared to the nine months ended September 30, 2023, due
to the revenue earned from the research and development services performed for Celltrion related to ABP-102 development. No such research
and development services revenue was earned during the nine months ended September 30, 2023. Our ability to generate product revenues
in the future will depend almost entirely on our ability to successfully develop, obtain regulatory approval for, and then successfully
commercialize a drug candidate, or enter into collaborations that provide for payments to us.

Operating Expenses
Research and Development Expenses
Research and development expenses
consist primarily of salaries, payroll taxes, employee benefits and stock- based compensation for those individuals involved in research
and development efforts, as well as consulting expenses, third-party research and development expenses, laboratory supplies and clinical
materials. The following tables summarize our research and development expenses by product candidate and program for the nine months ended

Research and development expenses
decreased by $0.6 million for the nine months ended September 30, 2024, as compared to the nine months ended September 30, 2023 primarily
due to the decrease in expenses associated with the SARS-CoV-2 neutralizing antibody program, partially offset by an increase in expenses
associated with the development of ABP-102. The overall decrease in expenses was a result of the Company's reduction in research
and development personnel and the use of consulting services.
General and Administrative Expenses
General and administrative
expenses consist primarily of compensation and benefits to our personnel, including the costs related to our management services agreements,
directors, and senior advisors; professional service fees, including accounting and legal services and other consulting services. General
and administrative expenses remained consistent for the nine months ended September 30, 2024, as compared to the nine months ended September
30, 2023, as the increases in salaries, wages, and accounting service expenses were offset by a decrease in legal, consulting, and travel
expenses.
Other Income, Net
Other income, net increased
to $3.3 million in income for the nine months ended September 30, 2024, from $45 thousand in income for the nine months ended September
30, 2023. This change is primarily due to the reversal of the approximately $3.5 million liability to one of the Company's research
and development providers as this provider informed the Company, as they are not pursuing collection on this liability.

Revenue
The collaboration revenue
decreased during the year ended December 31, 2023 compared to the prior period by $1.9 million. This decrease was primarily
driven by the revenue of $1.9 million recognized under the collaboration agreement with Celltrion related to ABP-102 in
2022. We did not generate any material revenue during the year ended December 31, 2023. Our ability to generate product revenues
in the future will depend almost entirely on our ability to successfully develop, obtain regulatory approval for, and then successfully
commercialize a drug candidate, or enter into collaborations that provide for payments to us.

Research and development expenses
decreased by $5.5 million for the year ended December 31, 2023 as compared to the year ended December 31, 2022 primarily
due to:
●
A decrease of $4.5 million in expenses associated with the research programs for the development of SARS-CoV-2 neutralizing antibodies responsible for COVID
●
A decrease of $0.8 million in milestone payments. In 2022 the Company made payments under the exclusive license agreement with Memorial Sloan Kettering Cancer Center ("MSK") for the research and development of ABP-100. The MSK License Agreement was terminated in September 2023.
In response to the global
pandemic, Abpro prioritized the development of therapeutic COVID-neutralizing antibodies through an internal discovery program and through
collaborations with third parties in the form of in- license agreements. Several candidate molecules were evaluated through
different stages of development. The most advanced molecule was developed through GMP manufacturing and evaluated in a clinical trial,
which represented a significant portion of the Research and development expenses above. However, the clinical trial was not successful.
Since the health threats from the COVID pandemic have now decreased, Abpro is not planning to focus on this area at this time.
General and Administrative Expenses
General and administrative
expenses consist primarily of compensation and benefits to our personnel, including the costs related to our management services agreements,
directors, and senior advisors; professional service fees, including accounting and legal services and other consulting services. General
and administrative expenses decreased by $1.4 million for the year ended December 31, 2023 as compared to the year ended December 31,
2022 primarily due to the decrease in stock-based compensation in connection with the issuance of options for consulting services in 2022
with the fair value of $1.7 million that were fully vested at the issuance date. The decrease was offset by an increase of $0.4 million
in accounting and audit fees.
Other Income (Expenses), Net
Other income (expenses), net
increased by $240 thousand, to $40 thousand in income for the year ended December 31, 2023 from ($200) thousand in expenses
for the year ended December 31, 2022. This change is primarily due to $225 thousand in interest expenses attributable to interest
accrued on unpaid vendor invoices incurred during the year ended December 31, 2022.

Liquidity, Capital Resources and Going Concern
Through the date of the Business
Combination with ACAB, the Company has financed its operations primarily through the sale of equity securities and issuance of promissory
notes and, to a lesser extent, through the revenue from collaboration arrangements. Since its inception, the Company has incurred significant
recurring losses, including a net loss of $3.9 million and $7.9 million for the nine months ended September 30, 2024, and 2023, respectively.
As of September 30, 2024, the Company had an accumulated deficit of $109.5 million. The Company expects to incur operating losses in the
foreseeable future.
While the Company completed
the Business Combination in November 2024, cash and cash equivalents will be insufficient to fund our operations, including clinical trial
expenses and capital expenditure requirements, for at least the next 12 months from the issuance date of our consolidated financial statements
as of September 30, 2024. We have concluded that these circumstances raise substantial doubt about our ability to continue as a going
concern within one year after the original issuance date of our annual financial statements. The Company is planning to raise additional
capital through equity or debt financing to meet its operating cash needs. The Company has based this estimate on assumptions that may
prove to be wrong, and the Company could exhaust its available capital resources sooner than it expects. There can be no assurance that
any required future funding can be successfully completed on a timely basis or terms acceptable to the Company.
On October 18, 2023, the Company
entered into a promissory note agreement with Abpro Bio International, Inc. ("ABI") to fund up to $6 million. The Company
received $5.2 million through the date of this filing.
On April 18, 2024, the Company
entered into a promissory note agreement with one of its executives to receive, as amended, up to $2.2 million in funding. The Company
received $2.0 million through the date of this filing.
On August 16, 2024, an executive
at ACAB provided a $103 loan to the Company and the Company agreed to repay a total of $206 at the earlier of i) November 20, 2024, and
ii) the closing of the Business Combination. On November 21, 2024, the note was amended and the liability to the ACAB executive was cancelled.
According to the terms of the amended note, the Company will repay the principal amount of $103.
On October 7, 2024, the Company
entered into an additional promissory note with ABI ("the 2024 ABI Note") to receive up to $1.0 million from ABI in weekly
installments of $250. The note accrues 10% interest and matures 5 business days after receipt of the proceeds under the PIPE Subscription
Agreements. The Company received $1.0 million under this note as of the Closing Date, and the balance of $1.0 million was repaid in connection
with the Closing.
In connection with the Closing
of the Business Combination, the Company received approximately $2,300.
Future Funding Requirements
The Company expects its expenses
to increase in connection with its ongoing activities, particularly as it advances the preclinical activities and clinical trials of its
product candidates. In addition, subsequent to the Closing of the merger, the Company expects to incur additional costs associated with
operating as a public company. The timing and amount of the Company's operating expenditures will depend largely on:
●
the
scope, number, initiation, progress, timing, costs, design, duration, any potential delays, and results of clinical trials and nonclinical
studies for the Company's current or future product candidates, particularly the planned Phase 1/2 clinical trial for ABP-102,
focusing on HER2+ breast and gastric cancers, as well as Phase 1 clinical trials for ABP-201 for the treatment of Wet AMD;
●
the
clinical development plans the Company establishes for its product candidates;
●
the
number and characteristics of product candidates and programs that the Company develops or may in-license;
73
●
the
outcome, timing and cost of regulatory reviews, approvals or other actions to meet regulatory requirements established by the FDA and
comparable foreign regulatory authorities, including the potential for the FDA or comparable foreign regulatory authorities to require
that the Company perform more studies for its product candidates than those that the Company currently expects;
●
the
Company's ability to obtain marketing approval for its product candidates;
●
the
cost of filing, prosecuting, defending and enforcing the Company's patent claims and other intellectual property rights covering
its product candidates, including any such patent claims and intellectual property rights that the Company has licensed pursuant to the
terms of its license agreement;
●
the
Company's ability to maintain, expand and defend the scope of its intellectual property portfolio, including the cost of defending
intellectual property disputes, including patent infringement actions brought by third parties against the Company or its product candidates;
●
the
cost and timing of completion of commercial-scale outsourced manufacturing activities with respect to the Company's product candidates;
●
the
Company's ability to establish and maintain licensing, collaboration or similar arrangements on favorable terms and whether and
to what extent the Company retains development or commercialization responsibilities under any new licensing, collaboration or similar
arrangement;
●
the
cost of establishing sales, marketing and distribution capabilities for any product candidates for which the Company may receive regulatory
approval in regions where the Company chooses to commercialize its products on its own;
●
the
success of any other business, product or technology that the Company acquires or in which the Company invests;
●
the
costs of acquiring, licensing or investing in businesses, product candidates and technologies;
●
the
Company's need and ability to hire additional management and scientific and medical personnel;
●
the
costs to operate as a public company in the United States, including the need to implement additional financial and reporting systems
and other internal systems and infrastructure for the Company's business;
●
market
acceptance of the Company's product candidates, to the extent any are approved for commercial sale; and;
●
the
effect of competing technological and market developments.
Until such time, if ever,
as the Company can generate substantial product revenue, the Company expects to finance its cash needs through a combination of equity
offerings, debt financings, collaborations, strategic alliances, and marketing, distribution or licensing arrangements with third parties.
To the extent that the Company raises additional capital through the sale of equity or convertible debt securities, the ownership interest
of the Company may be materially diluted, and the terms of such securities could include liquidation or other preferences that adversely
affect the rights of the Company's stockholders and the rights of the stockholders of the combined organization following the Closing
of the merger. Debt financing and preferred equity financing, if available, may involve agreements that include restrictive covenants
that limit the Company's ability to take specified actions, such as incurring additional debt, making capital expenditures or declaring
dividends. If the Company raises funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements
with third parties, the Company may have to relinquish valuable rights to its technologies, future revenue streams, research programs
or product candidates or grant licenses on terms that may not be favorable to the Company. If the Company is unable to raise additional
funds through equity or debt financings or other arrangements when needed, the Company may be required to delay, scale back or discontinue
the development and commercialization of one or more of its product candidates or delay its pursuit of potential in-licenses or acquisitions.

Net cash used in operating
activities for the nine months ended September 30, 2024, decreased by $0.1 million as compared to the nine months ended September 30,
2023. The decrease was primarily driven by the $0.1 million net changes in operating assets and liabilities mainly attributed to a decrease
in accounts payable and accrued expenses due to repayment with limited spending and an increase in accounts receivable due to timing of
payments under the collaboration agreement with Celltrion.
Net cash used in investing
activities decreased by $48 thousand for the nine months ended September 30, 2024, as compared to the nine months ended September 30,
2023. The Company purchased laboratory equipment during the nine months ended September 30, 2023. No property and equipment was purchased
during the nine months ended September 30, 2024.
Net cash provided by financing
activities increased by $4.7 million for the nine months ended September 30, 2024, as compared to the nine months ended September 30,
2023. During the nine months ended September 30, 2024, the Company received proceeds of $4.9 million from promissory notes with related
parties compared to $0 received during the nine months ended September 30, 2023. The proceeds from the promissory notes were partially
offset by $0.4 million in offering costs payments related to the Business Combination with ACAB.

Net cash used in operating
activities for the year ended December 31, 2023 decreased by $1.5 million as compared to the year ended December 31, 2022.
The decrease was primarily driven by the decrease in the research and development expenses of approximately $5.5 million, offset
by the decrease in share-based compensation of $1.7 million and $2.2 million net changes in operating assets and liabilities
mainly attributed to a decrease in accounts payable due to repayment with limited spending and an increase in accounts receivables due
to receipt of outstanding AR from a collaboration agreement.
Net cash used in investing
activities decreased by $17 thousand for the year ended December 31, 2023 as compared to the year of 2022. The Company purchased
the lab equipment for $48 thousand during the year ended December 31, 2023 and capitalized $65 thousand in patent costs
during the year ended December 31, 2022.
Net cash provided by financing
activities decreased by $8.9 million for the year ended December 31, 2023 as compared to the year ended December 31, 2022.
During the year ended December 31, 2023 the Company received proceeds of $1.4 million from a promissory note with ABI as compared
to proceeds of $10 million received from the issuance of Series F Preferred Stock in 2022. In addition, the Company paid $0.4 million
in offering costs in connection with the Business Combination during the year ended December 31, 2023.
Critical Accounting Policies and Estimates
This discussion and analysis
of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance
with US GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the
reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial
statements, as well as the reported expenses and net loss incurred during the reporting periods. Our estimates are based on our historical
experience and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making
judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ
from these estimates under different assumptions or conditions.
Our significant accounting
policies are described below. We believe that the accounting policies are critical for fully understanding and evaluating our financial
condition and results of operations.
75
Share-Based Compensation
The Company accounts for share-based
payments in accordance with Accounting Standard Codification Topic 718, Compensation—Stock Compensation ("ASC 718").
Under ASC 718, the Company measures, and records compensation expenses related to share-based payment awards (to employees and non-employees)
based on the grant date fair value using the Black-Scholes option-pricing model. The Company recognizes forfeitures related to employee
share-based payments when they occur. Forfeited share-based awards are recorded as a reduction to stock compensation expense.
The determination of the fair
value of share-based payment awards utilizing the Black-Scholes model is affected by the stock price and a number of assumptions, including
expected volatility, expected term, risk-free interest rate and expected dividends.
In determining the exercise
prices of options granted, the Company's Board has considered the fair value of the common stock as of the measurement date. The
fair value of the common stock has been determined by the Board at each award grant date based upon a variety of factors, including the
results obtained from an independent third-party valuation, the Company's financial position and historical financial performance,
the status of technological developments within the Company's proposed products, an evaluation or benchmark of the Company's
competition, the current business climate in the marketplace, the illiquid nature of the common stock, arm's length sales of the
Company's capital stock, including convertible preferred stock, the effect of the rights and preferences of the preferred stockholders,
and then prospects of a liquidity event, among others.
The Company does not have
a history of market prices of its common stock, and as such, volatility is estimated using historical volatilities of similar public entities.
The peer group was developed based on companies in the biotechnology industry. The Company will continue to apply this process until a
sufficient amount of historical information regarding the volatility of its own stock price becomes available. The expected term of the
awards is estimated based on the simplified method for grants to employees and is based on the contractual term for non-employee awards.
The risk- free interest rate assumption is based on observed interest rates appropriate for the terms of the awards. The dividend yield
assumption is based on history and expectation of paying no dividends.
Convertible Preferred Stock
The Company accounts for its
convertible preferred stock in accordance with the guidance in ASC Topic 480, "Distinguishing Liabilities from Equity" ("ASC
480"). Preferred stock subject to mandatory redemption (if any) is classified as a liability instrument and is measured at fair
value. Conditionally redeemable common stock (including preferred stock that features redemption rights that are either within the control
of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company's control) is classified
as temporary equity.
Emerging Growth Company Status
Section 102(b)(1) of
the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until
private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class
of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS
Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth
companies but any such election to opt out is irrevocable. Abpro has elected not to opt out of such extended transition period, which
means that when a standard is issued or revised and it has different application dates for public or private companies, New Abpro, as
an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This
may make comparison of New Abpro's financial statements with another public company, which is neither an emerging growth company
nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential
differences in accounting standards used.
New Abpro will remain an emerging
growth company until the earlier of (a) the last day of the fiscal year in which we have total annual gross revenues of $1.235 billion
or more; (b) the last day of the fiscal year following the fifth anniversary of the date of the completion of the initial public
offering of ACAB; (c) the date on which it has issued more than $1 billion in nonconvertible debt during the previous three years;
or (d) the date on which it is deemed to be a large accelerated filer under the rules of the SEC, which means the market value of
our common stock that is held by non-affiliates exceeds $700 million as of the prior second fiscal quarter end. For so
long as we remain an emerging growth company, it is permitted and intends to rely on exemptions from certain disclosure.

Overview
We are a biotechnology company
dedicated to developing next-generation antibody therapeutics with the goal of improving the lives of patients with severe and life-threatening
diseases. We are focused on novel antibody constructs for immuno-oncology and ophthalmology. By leveraging our proprietary
DiversImmune
®
and
MultiMab
TM
antibody
discovery and engineering platforms, we are developing a pipeline of next-generation antibodies, both independently and through collaborations
with global pharmaceutical and research institutions. Our two lead product candidates, ABP-102 and ABP-201, feature
our next generation tetravalent antibody format, or TetraBi antibody format, which binds to two different targets with two distinct binding
sites per target. ABP-102 is designed to redirect a patient's immune system to fight cancer by engaging T cells through co-targeting human
epidermal growth factor receptor 2, or HER2, and cluster of differentiation 3, or CD3, T-cell co-receptor. We plan initially
to develop ABP-102 for difficult to treat HER2+ solid tumors, focusing on orphan indications. ABP-201 is designed
to block blood vessel formation and normalize damaged vessels through co-targeting vascular endothelial growth factor, or VEGF,
and angiopoietin-2, or ANG-2. We plan to develop ABP-201 to treat vascular disease of the eye, focusing
on wet age-related macular degeneration (Wet AMD). We intend to follow these two lead product candidates with a broad pipeline
of CD3-targeting T-cell engagers based on the differentiated format of ABP-102. We expect to initiate clinical
trials for ABP-102 in the first half of 2026 and in the second half of 2026 for ABP-201.
ABP-102 is being developed
and commercialized through a worldwide strategic partnership with Celltrion Inc. ("Celltrion") (KRX:068270), a leading Korean
biopharmaceutical company headquartered in Incheon, South Korea, under a Collaboration Agreement entered into in September 2022 and amended
in October 2024. We received an initial milestone payment of $2.0 million from Celltrion in connection with this agreement. In addition,
we are eligible for net sales milestone payments of up to $1.75 billion and development milestone payments of up to $4.0 million
under that agreement. In 2022, we also received an equity investment in our Series F preferred stock of $2.0 million from Celltrion.
ABP-201 is being developed
and commercialized through a territorial partnership with Abpro Bio International, Inc. ("Abpro Bio"), a subsidiary of Abpro
Bio Co. Ltd (KOSDAQ:195990), a company formerly named Ugint Co Ltd with diversified holdings in precision machine tools, equipment and
biotechnology headquartered in Daegu, South Korea, under a collaboration and license agreement entered into in January 2020 that granted
Abpro Bio exclusive development and commercialization rights in the People's Republic of China, Japan, South Korea, Southeast Asia

DiversImmune
®
is
our antibody discovery platform that rapidly generates a diverse collection of proprietary antibodies against both clinically validated
and novel targets that have been traditionally difficult to access. This provides us with high affinity and high specificity antibody
building blocks with drug-like properties that we then use to engineer novel therapeutics.
MultiMab
TM
is
our engineering platform that provides us with the flexibility to combine these antibody building blocks in different combinations and
orientations to rapidly create "fit for purpose" novel full-length multi-specific antibody constructs. Our antibody constructs,
including our TetraBi antibody format, can potentially benefit patients with the goal of improved efficacy, better safety profiles, and
more convenient dosing regimens relative to current standard-of-care therapies. Furthermore, in contrast to single-format bispecific
antibody platforms that are only able to provide a single solution to different biological problems, our platform enables us to design
a diverse suite of full-length multi-specific antibody formats to address new problems in medicine. Our approach is designed to result
in therapeutic candidates with differentiated characteristics, including potentially stronger binding affinity, improved safety, more
convenient dosing regimens and streamlined manufacturing processes.
ABP-102: Next generation T-cell engager targeting
HER2 and CD3 for HER2+ solid tumors
ABP-102
Key Characteristics of ABP-102
●
Dual-arm affinity-tuned construct for
selective killing and cytokine release on HER2-high target cells, with reduced killing and cytokine release on HER2-low target cells
to reduce "on-target, off-tumor" toxicity
●
Bivalent HER2 binding to promote more selective
HER2-high target cell engagement
●
TetraBiTM IgG-[L]-scFv format with functionally
monovalent CD3 binding at the hinge region to prevent T cell activation in the absence of tumor cells
●
Cross-reactivity to human and cynomolgus CD3
for toxicity assessment
●
Engineered for reduced Fc receptor engagement
●
Symmetrical structure with natural antibody
features for efficient manufacturing and a potentially improved dosing profile
Our lead product candidate, ABP-102, is
a next generation immuno-oncology TetraBi antibody targeting HER2 and CD3 being developed for the treatment of HER2+ solid tumors, including
breast and gastric cancers. ABP-102 features bivalent HER2 binding sites and is engineered through affinity tuning to selectively
target tumor cells expressing high and intermediate levels of HER2, with reduced activity on cells expressing low-to-negative levels
of HER2. ABP-102 also features an affinity-tuned CD3 binding domain to provide enhanced potential for safety. ABP-102 harnesses
the power of the immune system by redirecting and activating cytotoxic T cells to attack tumor tissue. ABP-102 may provide an
improved therapeutic window to attack tumor cells while reducing systemic toxicity by promoting "on-target, on-tumor" effects,
with reduced potential for "on-target, off-tumor" toxicity toward endogenous tissues.
In preclinical in vitro studies, ABP-102 has
demonstrated selectivity in both cytokine secretion and cytotoxicity with HER2-high and intermediate breast, ovarian, and gastric cancer
cell lines, including those that are resistant to Herceptin (trastuzumab), with reduced activity on HER2-low and negligible
activity on HER2-negative cell lines. We plan to initiate a Phase 1/2 clinical trial of ABP-102 with our partner Celltrion in
the first half of 2026, focusing on HER2+ breast and gastric cancers.
We believe ABP-102 is
an improvement over currently approved HER2-targeting agents such as Herceptin, Perjeta (pertuzumab), and Kadcyla (T-DM1), as
well as other HER2-targeting agents currently in development, because it relies on the redirection of cytotoxic T cells to selectively
target and eliminate tumor cells, while sparing endogenous HER2-expressing cells. Current HER2-directed therapies, which are designed
either to block HER2 function or deliver toxic payloads to the tumor, are only effective in a subset of HER2+ patients, cause undesirable
side effects, and are limited by the onset of drug resistance.
78
It is management's belief
that ABP-102 has the potential to provide longer lasting or even curative results in a broader set of patients than are currently
addressed by HER2-directed therapies. The Global HER2+ market is forecast to grow to $12.1 billion by 2030, at a CAGR of 1.5%, according
to Research and Markets.
We believe the TetraBi antibody
format of ABP-102 provides a potentially transformative approach to immuno-oncology. The TetraBi antibody format features two
affinity-tuned binding sites, and thus bivalent binding for the tumor antigen, creating a stronger connection to the tumor cell compared
to monovalent binding. In addition, the placement of the CD3 binding domain in the middle, or hinge region, of the TetraBi antibody format
results in a therapeutic candidate that, in preclinical studies, selectively activates T cells only in the presence of tumor cells. We
have designed ABP-102 with the goal of a favorable safety profile and potential for an enhanced therapeutic window.
We are leveraging the TetraBi
antibody format of ABP-102 to pursue a broad pipeline of immuno-oncology agents that target highly expressed antigens on a diverse
range of tumor types, as depicted in the following chart. Our platform of T cell engagers has the potential to translate into an industry-leading
pipeline of therapeutic agents with the goal of improving the treatment of patients.

ABP-201: Ligand trap targeting VEGF and ANG-2 for
vascular diseases of the eye
ABP-201
Key characteristics of ABP-201
●
Dual inhibition of VEGF and ANG-2 to
block angiogenesis
●
Four high-affinity binding sites for increased
potential potency
●
Dual targeting in single molecule
●
Natural antibody structure for potentially improved
dosing
●
Symmetrical structure for efficient manufacturing
ABP-201 is a different
TetraBi antibody format, designed to simultaneously inhibit VEGF and ANG-2 for the potential treatment of vascular diseases
of the eye, including diabetic macular edema, or DME, and wet age-related macular degeneration, or Wet AMD. In both DME and
Wet AMD, blood vessels form abnormally and leak fluid, resulting in vision loss. Whereas VEGF drives new blood vessel formation, ANG-2 acts
to destabilize blood vessels and contributes to vessel leakage. The current standard of care for DME and Wet AMD includes intravitreal
injections of VEGF-targeted agents, including Eylea (aflibercept), Lucentis (ranibizumab), and Avastin (bevacizumab, used off-label). However,
these drugs require eye injections every one to two months and are only effective in a subset of patients, many of whom eventually develop
resistance. Because ABP-201 has a high binding capacity, with a total of four binding sites per molecule, we believe ABP-201 could
be administered less frequently than current agents. Recently, the VEGF and ANG-2 co-targeting agent Vabysmo (faricimab),
was approved by the FDA, and clinical trial results showed a dose-dependent improvement in best-corrected visual acuity relative to Lucentis,
providing strong support for this approach. In 2022, the combined worldwide sales of Eylea and Lucentis exceeded $10.5 billion according
to company filings. Through our AbMed subsidiary, we have in-licensed certain intellectual property rights relating to ABP-201 from MedImmune
(now AstraZeneca), and are in breach of the terms of our license agreement with MedImmune/AstraZeneca.
Clinical Development Plan
We plan to conduct a Phase
1, multiple-ascending dose evaluation of the safety and initial efficacy of ABP-201 in patients with wet age-related macular
degeneration (Wet AMD). Following the identification of the maximum tolerated dose (MTD) or the safety and tolerability of the maximum
administered dose (MAD), a larger randomized phase 2 study is planned.
We have an experienced leadership
team with significant industry know-how and deep experience in antibody discovery and development, biomarker discovery and validation,
clinical development and regulatory approval, partnerships, operations, and corporate finance. Our leadership team has broad industry
experience from working at pharmaceutical and Biotech companies, including Celgene, NantWorks, Frequency Therapeutics and Moderna. We
also have a group of scientific advisors comprised of leaders in our industry across various disciplines, including Robert Langer, PhD,
David H. Koch, Professor at MIT and a co-founder of Moderna; Laurie Glimcher, MD, President and CEO of the Dana-Farber Cancer
Institute; Ron Levy, MD, Professor and Chief, Division of Oncology, Stanford School of Medicine; George Tsokos, MD, Professor of Medicine,
Beth Israel Deaconess Medical Center; Dr. Shiv Pillai, PhD, Professor of Medicine, Harvard Medical School and Massachusetts General
Hospital and Steven Schnittman, MD, PhD, who previously served as Medical Branch Chief of the AIDS division at the National Institutes
of Health and Vice President, Global Clinical Research at Bristol Myers Squibb. Dr. Langer is a member of our board of directors,
and the other advisors serve on our Scientific Advisory Board.

Our Pipeline
Our
DiversImmune
®
and
MultiMab
TM
platforms
and licensing strategy have generated a pipeline of next-generation antibody product candidates, as reflected in the following table:
ABP-201 is held through
our majority-owned subsidiary AbMed Corporation, or AbMed. AstraZeneca (formerly MedImmune) owns a minority stake in AbMed and, with respect
to Asia, the Middle East and certain other countries, ABP-201 is being developed and commercialized through a territorial partnership
with Abpro Bio, with our company retaining rights in the rest of the world. ABP-102 is being developed and commercialized through
our world-wide strategic partnership with Celltrion. We hold world-wide exclusive rights to ABP-110 under a patent license granted
by the National Cancer Institute, or NCI, a division of the NIH. ABP-150 is being developed under a collaboration agreement
with Nanjing Chia Tai Tianqing Pharmaceutical Co., Ltd ("NJCTTQ"), pursuant to which NJCTTQ has exclusive commercialization
rights in China and Thailand and we retain commercialization rights in the rest of the world.
Our Strategy
Our mission is to develop
next-generation antibody therapeutics with the goal of improving the lives of patients with severe and life-threatening diseases. Traditionally,
creating antibodies against targets and validating them as potential therapies has been time consuming and labor-intensive. We believe
that our proprietary antibody platforms and approach overcome these limitations, however, we have yet to (i) produce antibodies on
a scale needed for clinical trials or commercialization or (ii) evaluate any of our product candidates in a patient. By leveraging
the speed, quality, and target-access of our
DiversImmune
®
platform, we have generated a proprietary collection
of antibody building blocks that enable us to establish our own pipeline of next-generation antibody product candidates. We believe our
ability to leverage our
MultiMab
TM
platform to design novel bi-and multi-specific antibody constructs
with natural, antibody-like structures presents a significant opportunity to unleash the immune system's natural ability to fight
disease and to elicit responses from broader patient populations.
Our key strategies to achieve
this mission are:
●
Aggressively
advance our lead product candidates, ABP-102 and ABP-201, into the clinic
. We plan to initiate a Phase 1/2 clinical
trial of ABP-102 in the first half of 2026, focusing on HER2+ breast and gastric cancers. Additionally, we are planning to
advance ABP-201 into Phase 1 clinical trials also in the second half of 2026 for the treatment of Wet AMD. We believe that
the development of our lead antibody product candidates, if successful, will generate substantial value and provide us with differentiated
products to pursue in large markets with significant unmet medical needs. IND-enabling studies are underway for both lead product
candidates in preparation for final GLP toxicity studies and GMP manufacturing for filing the IND and we will request Pre-IND meetings
beforehand with the FDA when appropriate.
●
Rapidly
follow ABP-102 with a broad pipeline of CD3-targeting T-cell engagers and leverage this approach to other immune
cell targets
. We are building on the optimized format of ABP-102 to aggressively develop a suite of immuno-oncology agents
that redirect T cells to a diverse range of liquid and solid tumors. ABP-110, targeting GPC3 on hepatocellular carcinoma, and ABP-150, targeting
Claudin 18.2 on gastric cancer, are currently in preclinical development. We may also use this "pipeline in a format" strategy
with other immune cell targets, including CD137 and CD47.
81
●
Leverage our
DiversImmune
®
and
MultiMab
TM
platforms to grow our pipeline of antibody product candidates
. We plan to continue investing in our
DiversImmune
®
and
MultiMab
TM
platforms to maintain our competitive advantage. We will continue to expand our collection of high affinity and high specificity antibody building blocks against both clinically validated and novel therapeutic targets, and apply our "fit for purpose" antibody engineering approach to construct novel multi-valent, multi-specific therapeutic product candidates. We will continue to build on the success of existing immuno-oncology or cell therapies that use the power of T cells to fight cancer, such as chimeric antigen receptor T-cell, or CAR T, therapy, but will focus on simpler, more accessible, and less expensive approaches that provide a universal solution for large populations of cancer patients.
●
Continue to explore and execute strategic collaborations
. In addition to the development and commercialization collaborations we have entered into with Celltrion and Abpro Bio, we entered into a collaboration agreement in January 2019 with NJCTTQ, a pharmaceutical company specializing in research and development, production and commercialization of drugs for cardiovascular diseases, tumors, perioperative care, gastrointestinal disorders and urologic diseases headquartered in Nanjing, China, for the development of novel bispecific antibody therapies for immuno-oncology, including potentially best in class T-cell engagers. Under that agreement, we are jointly developing ABP-150, a T-cell engager designed to fight cancer through co-targeting CD3 and Claudin 18.2. NJCTTQ has exclusive commercialization rights in China and Thailand and we retain commercialization rights in the rest of the world. We will continue to explore strategic and geographic-oriented partnerships that provide us with near-term economic benefits where we retain product rights to key strategic markets.
●
Build a leading fully integrated discovery-to-commercial antibody therapeutics company
. We have assembled an experienced scientific and business team, and have built robust discovery and antibody engineering platforms that allow us to create a broad pipeline of novel product candidates. As we advance our product candidates into clinical development, we intend to complement our discovery and development strengths with clinical expertise and commercial capabilities to build a fully integrated company.
Introduction to Monoclonal and Dual-Targeting Antibodies
Antibodies are large and diversified
proteins produced by B cell immune responses to counter threats including infectious entities such as viruses, bacteria, and fungi. Antibodies
can be raised against antigens seen by the immune system as "non-self," and therefore antibodies against human proteins
are often raised using a variety of immunization strategies in mice or other animals. The resulting antibodies can then be used as building
blocks to develop therapeutics for molecular targets, including proteins overexpressed on the surface of cancer cells. Because they recognize
their target antigens with high affinity and high specificity, and because they are natural elements of the immune system, antibodies
have been used effectively as drugs for over 30 years. Monoclonal antibodies are the largest and most rapidly growing class of therapeutic
proteins and have become a mainstay of therapeutic options for patients with cancer, autoimmune disorders, and other diseases. As of June 30,
2022, 162 antibody therapies have been approved by at least one regulatory agency in the world, including 122 approvals in the United
States.
An immunoglobulin G, or IgG,
is the most common type of antibody and comprises two identical heavy chains and two identical light chains, which assemble to form a Y-shaped molecule,
as depicted in the following graphic. The bottom tail of the "Y" is called the fragment crystallizable, or Fc, region, and
is structurally constant across entire classes of antibodies. The Fc region of an antibody interacts with a variety of receptors on immune
cells and is also responsible for the long circulating half-life of an antibody. The tips of the "Y" are called the fragment
variable, or Fv, regions, and contain the antigen-binding sites. A natural antibody recognizes a single target antigen and is therefore
"monospecific." Because it features two identical binding sites, however, it is "bivalent" for that target. Bivalency
is a critical feature of natural antibodies. Just as it is much easier to hang from a bar with two arms rather than one, bivalent binding
has been shown in preclinical studies to provide a much stronger connection to the target antigen than would be possible with monovalent
binding.
Although natural antibodies
recognize a single target, they can be engineered in different ways to bind two or more targets, resulting in a bispecific or multispecific
antibody. While there are many different types of dual-targeting antibodies, several mechanisms of action can be implemented for a bispecific
construct, including dual binding, cross-linking, and cell-cell bridging, as depicted in the following graphics.

Our Platforms
Our approach consists of two
technology platforms: our
DiversImmune
®
platform, which we use to generate therapeutic "building
blocks," which are high affinity and high specificity antibodies with functional activity against therapeutic targets; and our
MultiMab
TM
platform,
which we use to construct therapeutic product candidates by assembling the building blocks into different combinations of bi- and
multi-specific antibodies. Together, these platforms support our strategy of building a broad pipeline of next generation antibody therapeutics
that are designed to address a wide range of human diseases.
DiversImmune
®
: Our antibody discovery platform
Our
DiversImmune
®
platform
was built to address a key bottleneck in the antibody therapeutics industry: the ability to rapidly generate high affinity and high specificity
antibodies against virtually any target of interest. Although
in vitro
methods, such as phage and yeast display, have
been developed to mimic the immune system, these methods typically rely on collections of antibodies from unimmunized donors and as a
result generally yield relatively low affinity antibodies. Improving these antibodies through affinity maturation (
i.e.
, mutation
and selection) is often a lengthy process and is not always successful. In contrast, the adaptive immune system of a mouse has a built-in mechanism
called somatic hypermutation that improves the affinity of antibodies up to one thousand times, yielding high affinity and high specificity
antibodies suitable for therapeutic development.
The greatest challenge with
mouse-based methods, however, lies in generating a strong and diverse immune response to the target of interest. The mammalian immune
system has a mechanism called tolerance that prevents it from making antibodies against proteins that are perceived as "self."
Thus, to generate a strong immune response against a target that is difficult to access, either because the target is not particularly
immunogenic, or capable of producing an immune response, or because the target, a human protein, is very similar to the corresponding
mouse protein, it is necessary to "break tolerance." A key component of our
DiversImmune
®
platform
is our genetically engineered hyperimmune mouse which seeks to solve this problem in two ways. First, the mouse has been genetically engineered
so that more of its antibody-generating B cells survive and proliferate than in a non-engineered mouse. This results in a larger
and more diverse collection of high affinity antibodies. Second, the mouse has a hyperactive immune system in which its tolerance to self-antigens
has been "broken." This enables us to generate a diverse array of antibodies against a wide range of targets, including targets
that are very similar between mouse and human.
The
DiversImmune
®
platform
comprises three key steps, all focused on generating a diverse collection of high quality antibodies:
1.
Immunization
. We have developed an integrated collection of immunization methods, termed Raptor, which includes purified proteins, engineered cells, viral-like particles, and DNA. These methods all work in concert with the goal to elicit a strong and diverse immune response.
2.
Diversification
. We have developed hyperimmune mouse, along with a variety of co-stimulation methods, to optimize the immune response to each target and yield a diverse collection of antibodies that recognize different epitopes, or binding regions, on the same target protein. This is a critical component of our discovery process as we believe it greatly increases the probability of identifying antibodies with the desired functional properties necessary for therapeutic development.
3.
Optimization
. We have streamlined the processes of humanization and optimization so that we can rapidly advance antibodies with the desired functional properties to fully developed building blocks. These building blocks can then be assembled into novel therapeutic product candidates using our
MultiMab
TM
platform.
To date, our
DiversImmune
®
platform
has been used to generate antibodies for pharmaceutical and biotechnology companies. We are now using this platform internally to create
what management believe to be an industry-leading collection of building blocks to support a growing pipeline of therapeutic product candidates.
84
MultiMab
TM
: Our antibody engineering
platform
Our
MultiMab
TM
platform
enables us to build a diverse array of bi-and multi-specific antibody formats, allowing us to optimize the format of our product
candidates. Because biology is diverse and complex, there is no "one size fits all" solution to engineering multi-specific
antibodies. Instead, different problems call for different solutions. We draw from a suite of different antibody formats to choose the
one that we believe best suits the disease and mechanism we are targeting. Despite having multiple formats from which to choose, our formats
typically contain two key features:
1.
Bivalent binding
. Bivalent binding, or binding with two points of contact, takes advantage of the concept of avidity, specifically that multipoint connections are much stronger than single point connections. In order to maximize efficacy, we build bivalent binding into our therapeutic product candidates where increased strength of binding is desirable. For example, ABP-102 features two identical binding sites for HER2, rather than one. This enables the molecule to bind tightly to HER2+ tumor cells, forming a strong immunological synapse, or cell-to-cell interaction, between the tumor cell and the cytotoxic T cell. We believe this is critical to generating a strong and sustained immune response and differentiates ABP-102 from other T-cell engaging bispecific antibodies that only feature a single binding site for the tumor-specific antigen.
2.
Fc region
. The Fc region of an antibody interacts with various receptors on immune cells to control both the immune response to antibody binding and the circulating half-life of an antibody. To take advantage of these natural functions, we build Fc regions into all our therapeutic product candidates. For example, ABP-102 features a human IgG1 Fc region that promotes a long circulating half-life, and has been further engineered to reduce or eliminate antibody-dependent cell-mediated cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC) to reduce potentially harmful side-effects associated with inflammation and cytokine release. Similarly, ABP-201 features an Fc region that results in greater stability and, due to its size, a longer ocular half-life, potentially enabling more convenient dosing for patients.
Both of our lead product candidates, ABP-102 and ABP-201, are
TetraBi antibodies that feature two high affinity binding sites for each of their targets and Fc regions for longer half-lives. In addition,
both product candidates are symmetrical, with two identical heavy chains and two identical light chains. Many bispecific antibody formats
are asymmetrical, featuring two different heavy chains. This creates the possibility of chain mispairing, which complicates the manufacturing
process as it is necessary to rigorously characterize each batch and minimize the presence of mispaired species. With our TetraBi antibody
format, this allows for straightforward manufacturing, as there is no possibility of chain mispairing.
MultiMab

85
Key advantages of our antibody technology platforms
We believe our
DiversImmune
®
and
MultiMab
TM
platforms
overcome several significant limitations associated with competing antibody technologies and have the following key competitive advantages:
●
Superior target access
. By breaking immune tolerance, our
DiversImmune
®
platform enables us to generate high quality antibodies against traditionally difficult-to-target proteins, providing access to new therapeutic targets.
●
Superior speed of antibody discovery
. By generating a wide diversity of high quality antibodies against a single target, our
DiversImmune
®
platform accelerates the discovery phase by increasing the probability of identifying high quality antibodies with the appropriate function. This speed allows us to rapidly scale and build a broad portfolio of functional building blocks to address disease-specific challenges that are not currently met by existing therapeutics or products. However, any product candidate developed with our platforms will still be subject to clinical trial requirements prior to approval, and we cannot accelerate clinical trials.
●
Superior flexibility in engineering novel therapeutics
. By providing access to a diverse array of bi- and multi-specific antibody formats, our
MultiMab
TM
platform enables us to rapidly test a broad range of solutions, shortening the timeline for lead selection and increasing the chance of finding an optimal format that meets key performance specifications.
B cell cloning platform
In addition to our
MultiMab
TM
platform
we have developed a B cell cloning platform that enables us to isolate potently neutralizing antibodies to SARS-CoV-2, RSV,
and other viruses recognizing conserved viral epitopes resistant to mutational escape.
Our Immuno-Oncology Strategy For T Cell Engagement
One of the most promising
strategies in cancer therapy is to direct cytotoxic T cells to kill tumor cells. This can be achieved using dual-targeting antibodies,
which bind simultaneously to a tumor-specific antigen on a tumor cell and to CD3 on a T cell, bringing these cells into close proximity
and causing the T cell to kill the tumor cell. First-generation bispecific antibodies were called Bispecific T-cell Engagers,
or BiTEs, and contained two Fv regions, one for the tumor antigen and one for CD3. Because they do not contain an Fc region, BiTEs have
very short circulating half-lives, requiring patients to wear an infusion pump for continuous intravenous administration. Second-generation
bispecific antibodies contain an Fc region, but typically have only one binding site for the tumor antigen. This results in weaker binding
to the tumor cell than could be achieved with the corresponding bivalent antibody.
86
Key features of the TetraBi antibody format for T-cell engagement
Abpro's TetraBi antibody
format improves upon both first-and second-generation bispecific T-cell engaging antibodies, as summarized in the following
table. First, unlike first-generation bispecific antibodies, our TetraBi antibodies contain an Fc region, which provides enhanced
stability and a longer circulating half-life for potentially more convenient dosing. Second, unlike second-generation antibodies, our
TetraBi antibodies have two binding sites for the tumor antigen, rather than one. Bivalent binding promotes maximal efficacy via an avidity-based
binding effect for the tumor associated antigen, allowing for the establishment of strong connections between the T cell and the tumor
cell, leading to sustained activation through clustering of the T cell receptor complex in the presence of high antigen densities. By
placing the CD3-binding domain in the hinge region of the molecule, the TetraBi antibody format has been shown in preclinical
studies to exhibit monovalent-like interaction with CD3. This is important in preventing TetraBi antibodies from activating T cells in
the absence of tumor cells, which could lead to undesirable toxicities such as cytokine release syndrome, or CRS, a potentially life-threatening
toxicity associated with T cell targeted therapies. Finally, unlike second-generation antibodies, our TetraBi antibodies contain two identical
heavy chains and two identical light chains. This allows for easy manufacturing, as there is no possibility of mispairing between two
different heavy chains.
Key advantages of our TetraBi antibody format
Our lead product candidate, ABP-102, illustrates
the key advantages of this format. ABP-102 is bivalent for HER2, providing stronger binding to tumor cells than could be achieved
with first- and second-generation formats that are monovalent for HER2. ABP-102 has been shown in preclinical mouse studies
not to activate T cells in the absence of tumor cells, but induce T cells to kill tumor cells in a HER2-dependent manner.
87
We believe the TetraBi antibody
format of our ABP-102 product candidate offers several significant competitive advantages over other bispecific antibody formats
and other approaches to T-cell-based therapy:
●
Bivalent binding
. By including two binding sites for the tumor antigen, our antibodies are designed to form a much stronger connection to tumor cells than competitor molecules that feature only a single binding site.
●
Potentially better dosing through inclusion of an Fc region
. By including an Fc region, our TetraBi antibodies are designed to have long circulating half-lives, enabling potentially more convenient dosing for patients.
●
Controlled immune effector function through Fc engineering
. By introducing defined mutations into the Fc region, we are potentially able to diminish or eliminate Fc-mediated interactions that can contribute to unwanted side effects such as CRS.
●
Lower immunogenicity
. By closely resembling human antibodies with natural amino acid sequences, our TetraBi antibodies may have a reduced risk of being immunogenic, or capable of producing an undesirable immune response, which could otherwise lead to decreased efficacy.
●
Streamlined manufacturing
. By building symmetrical molecules with two identical heavy chains and two identical light chains, our molecules are designed to eliminate complications arising from potential chain mispairing.
Advantages of TetraBi antibodies over CAR T
therapy
T cells can also be directed
to kill tumor cells by genetically modifying them to express a chimeric antigen receptor, or CAR. A CAR is a synthetic receptor in which
an Fv domain of an antibody that recognizes a tumor-specific antigen is linked to a portion of the T-cell receptor, typically CD3-zeta, as
well as one or more costimulatory domains. T cells expressing a CAR, or CAR T cells, bind to and subsequently kill tumor cells expressing
the appropriate antigen. CAR T therapy has demonstrated efficacy in liquid tumors and as of 2023, six CAR T therapeutics have garnered
FDA approval, including agents targeting hematological malignancies such as lymphomas, leukemias, and multiple myeloma. However, there
are currently no approvals in solid tumor indications. Unlike antibody therapy, CAR T therapy is a complex, multi-step process. After
a patient's white blood cells are collected, T cells are isolated and activated. They are then genetically engineered to express
the CAR. The CAR T cells then need to be grown for several weeks before being infused back into the patient. Prior to infusion, however,
patients have to undergo chemotherapy to deplete immune cells, providing an opportunity for the CAR T cells to engraft in the patient.
Despite the effectiveness of this approach, there are several challenges to the widespread adoption of CAR T therapy. The process of engineering
CAR T cells is technically challenging, time-consuming, and expensive. In addition, there are significant toxicities associated with CAR
T therapy, including CRS. Although patients receiving CAR T therapy are often treated for CRS while undergoing therapy, treatments for
CRS, namely administration of immuno-suppressive agents, can also reduce the efficacy of the therapy.
While we have yet to observe
any advantages of TetraBi antibodies in a clinical trial, and TetraBi antibodies have not yest received marketing approval, we believe
our next-generation CD3-targeted T-cell engagers have several advantages over CAR T therapies. Like CAR T therapy, we are
redirecting cytotoxic T cells to fight cancer. Unlike CAR T therapy, however, potential treatment with our TetraBi antibodies should be
straightforward and convenient for patients. They will not be required to travel large distances to state-of-the-art cancer
centers, but may instead be treated by simple intravenous infusion in local clinics. They will not be required to wait weeks for their
T cells to undergo a lengthy and complex modification process, and they will not need to undergo chemotherapy to deplete their immune
cells. It will also be potentially much easier to manage toxicities by altering the dose of the antibody. Finally, our TetraBi antibody
therapy is expected to be less expensive, reducing obstacles associated with payment and reimbursement.

(Prescient & Strategic Intelligence).
Our Product Candidates
ABP-102 for HER2+ breast and gastric cancers
Our lead product candidate, ABP-102, is
a TetraBi antibody targeting HER2 and CD3. It is an affinity-tuned, Fc engineered dual-targeting antibody with a human IgG1-like structure. ABP-102 features
two binding sites for bivalent binding to cells expressing HER2, and two binding sites for CD3 in a format that promotes functional monovalency
during cell binding. We believe this structure provides greater potential for clinical applications compared with other HER2-directed T-cell-engaging bispecific
antibodies that have only one binding site for the tumor-specific antigen (
i.e.
, HER2), allowing for an avidity-enhanced effect. ABP-102 is
designed to redirect T cells to tumor cells that are overexpressing HER2 at high or intermediate levels. In preclinical studies, we have
shown that ABP-102 selectivity promotes T cell activation, cytokine release and cytotoxicity in the presence of HER2-high and
intermediate expressing cells, including HER2+ breast, ovarian, and gastric cancer cell lines. We have also observed reduced or no cytotoxic
activity against cell lines expressing low/endogenous levels of HER2. This feature provides the opportunity for an improved therapeutic
window to attack tumor cells while reducing systemic toxicity by promoting "on-target, on-tumor" effects, with
reduced potential for "on-target, off-tumor" toxicity toward endogenous tissues. We plan to initiate clinical
trials of ABP-102 in the first half of 2026 with our partner Celltrion, focusing on HER2+ breast and gastric cancers.
Background and market opportunity for HER2+ breast and gastric cancers
Breast cancer is the most
common cancer in women in the United States, except for skin cancers. It is about 30% (or 1 in 3) of all new female cancers each year.
The American Cancer Society's estimates for breast cancer in the United States for 2023 are: About 297,790 new cases of invasive
breast cancer will be diagnosed in women. About 55,720 new cases of ductal carcinoma in situ (DCIS) will be diagnosed. About 43,700 women
will die from breast cancer. Breast cancer is the second leading cause of cancer death in women (only lung cancer kills more women each
year). The chance that a woman will die from breast cancer is about 1 in 39 (about 2.5%). The American Cancer Society's estimates
for stomach cancer (also known as gastric cancer) in the United States for 2023 are approximately 26,500 new cases (15,930 in men and
10,570 in women) and approximately 11,130 deaths (6,690 men and 4,440 women). Stomach cancer accounts for about 1.5% of all new cancers
diagnosed in the United States each year, according to the American Cancer Society.

Potential competitive advantages of ABP-102 versus approved
anti-HER2 therapies
Current HER2-directed therapies
have demonstrated increased chemical off target toxicity (e.g., TKIs and ADCs) and/or reduced efficacy from drug resistance or limited
potency requiring combination with chemotherapy (i.e., mAbs), especially in the relapsed and refractory disease population. ABP-102 seeks
to overcome these challenges as a single-agent therapy that potently engages the patient's natural immune system without toxic chemicals
to directly target and destroy the tumor.
Potential benefits of ABP-102 in immuno-oncology
ABP-102 is a TetraBi
antibody that is designed to bind simultaneously to HER2 overexpressed on a tumor cell and CD3 on a T cell, thereby bringing the two cells
into close proximity and promoting T-cell activation that leads to killing of the tumor cell. ABP-102 is a differentiated
therapeutic in that it is able to selectively target HER2-high and intermediate expressing cells, with reduced activity on HER2-low or
negative cells, an engineered design feature to promote safety for endogenous HER2-expressing tissues. The TetraBi antibody format of ABP-102 is
intended to improve on the clinical efficacy of HER2 targeted therapy by inducing infiltration of T cells into HER2+ tumors. In addition
to HER2+ breast cancer, ABP-102 can potentially target any solid tumor in which HER2 is overexpressed, including HER2+ gastric,
esophageal, endometrial, ovarian, colorectal, lung, pancreatic, cervical, gallbladder, and bladder cancers, as well as HER2+ pediatric
indications including osteosarcoma. By targeting both HER2 and CD3, ABP-102 may overcome many of the limitations of single-targeting
agents. For instance, agents targeting HER2 alone, such as Herceptin, face problems with drug resistance, often caused by alterations
in the HER2 signaling pathway or other related pro-proliferative pathways.
ABP-102 works by a different
mechanism, engaging cytotoxic T cells to kill the tumor cells rather than blocking the function of HER2. As such, we believe that ABP-102 could
lead to more durable responses in patients, with reduced risk of drug resistance. Furthermore, ABP-102 possesses an advanced
TetraBi antibody format, unlike that of competing agents that only feature a single binding site for HER2. Having two binding sites for
HER2 enables higher binding potential and selectivity for tumor cells, which may result in greater potency and an improved therapeutic
index. In addition, this dual binding may provide access to a broader patient population, including patients that express intermediate
levels of HER2.
ABP-102
immune-mediated
HER2+ tumor cell death
90
Preclinical data
For ABP-102 to be
both safe and effective, it must only activate T cells when HER2+ tumor cells are present. The key safety risk for T-cell engaging
therapies is CRS, in which T cells and other white blood cells become activated, leading to the over-production of pro-inflammatory cytokines.
This can cause high fever, swelling, redness, extreme fatigue, nausea, and, in rare cases, death. The ABP-102 Fc region is engineered
to have reduced binding to Fc receptors and C1q, thereby making T cell engagement the definitive mechanism of action. By positioning the CD3-binding domain
near the hinge region of the molecule, it selectively activates T cells only in the presence of HER2+ tumor cells. Thus, when ABP-102 is
added to T cells or PBMCs alone, the T cells do not release pro-inflammatory cytokines like TNFa, IL-6, IL-2and IFNg.
When HER2+ tumor cells are introduced, however, ABP-102 causes potent activation of the T cells, along with cytokine release
reflecting T cell activation. This strong dependency on HER2 for T cell engagement may result in a beneficial therapeutic index for ABP-102, enabling
a dose to be found that is both safe and effective. In addition, HER2 is expressed at lower levels in some tissues of the human body,
including heart and lung tissues. Therefore, we have engineered ABP-102 to promote selectivity for T cell activation and killing
of HER2-high and intermediate target cells, which is a key differentiating feature.
In preclinical in vitro studies, ABP-102 has
shown strong antitumor activity that is dependent on the presence of CD3-positive T cells, a key component of cellular immunity
within human peripheral blood mononuclear cells, or PBMCs. PBMCs consist of monocytes and lymphocytes, which are white blood cells made
up of T cells, B cells, and natural killer, or NK cells.
We have tested ABP-102 for
cytotoxicity on a wide variety of cell lines with a broad range of HER2 surface expression levels, from high to intermediate to low, as
determined by flow cytometry with trastuzumab biosimilar antibody (Figure 1). These cell lines include HER2-high expressing cell lines
such as SKBR-3, BT-474, and NCI-N87, and also HCC1954 breast cancer cells, which are HER2+, but resistant to
Herceptin. ABP-102a, b, and c lead candidate affinity-tuned constructs were all able to kill all cell lines expressing high-to-intermediate HER2
levels at a similar dose range for maximum cytotoxicity to the parental HER2 x CD3 TetraBi construct with unmodified HER2 and CD3 affinity. MDA-MB-453 cells
are reported to be HER2 intermediate in the literature, and this was similar in our flow cytometry assessment; ABP-102 similarly
shows killing of that cell line as well. However, in contrast to the HER2 x CD3 parental TetraBi antibody, ABP-102a, b, and
c have reduced activity on HER2 low-to-negative cells, including the ZR-75-1, MCF-7, HT55, JIMT-1 cell
lines, in which erbb2/HER2 gene expression is not amplified.
In these studies, ABP-102a, b
and c exhibited selective cytotoxicity in the presence of human PBMCs that was dependent on HER2 expression level, with preferential killing
of HER2-high expressing cell lines and reduced activity on HER2-low cell lines. This selectivity for targeting of HER2-high
expressing cells may help to widen the therapeutic window of a T cell engager with less potential for toxicity toward tissues expressing
endogenous levels of HER2.
Figure 1. ABP-102 is effective in
vitro against a range of cancer cell lines expressing high and intermediate HER2 levels, but shows reduced activity on HER2 low to negative
cell lines.
Figure 1 legend
:
Cell lines were harvested with Accutase followed
by staining with 1 ug/mL trastuzumab biosimilar antibody, followed by staining with anti-human IgG-PE secondary antibody. Flow
cytometry data were collected using a BD FACSCelesta and analyzed in FlowJo software as quantified by median fluorescence intensity (MFI).
For cytotoxicity analysis, PBMCs were added at a 10:1 E:T ratio (100,000 PBMCs: 10,000 seeded target cells) and incubated with antibodies
for 42 hours, at which time cytotoxicity was quantified using the CellTiterGlo2.0 protocol for each cell line. Lead clones ABP-102a, b,
and c are shown as compared to a positive control (non-affinity tuned CD3 x HER2 parental TetraBi), as well as a comparator
molecule (HER2 x CD3 monovalent heterodimer). An isotype control bispecific antibody with an intact CD3 binding arm was used as a negative
control.
91
To determine whether T cell
activation differences account for the observed differential activity on HER2-high and intermediate cells, we assessed culture supernatants
for cytokine release (Figure 2). Similar cytotoxicity is observed with ABP-102a, b, and c on the HER2-high (SKBR-3) cell
line, with a modest reduction in cytokine release compared to the HER2 x CD3 parental control TetraBi molecule. However, when using cell
lines with HER2-low expression (MCF-7) as target cells, we observe less cytotoxicity with ABP-102a, b, and
c as compared to the HER2 x CD3 parental control TetraBi molecule. On HER2-low expressing cells, we also observe a markedly
reduced cytokine release profile, reflecting reduced activation of T cells as compared to the HER2 x CD3 parental control TetraBi molecule.
This data demonstrates the
selectivity of our ABP-102 candidate lead molecules, a feature which should help to promote cytotoxicity for HER2 overexpressing
cells while potentiating an environment for durable T cell responses, while also mitigating risks to endogenous HER2-expressing tissues
including the heart and lungs.
Figure 2. ABP-102 exhibits selectivity
for HER2 overexpressing cells through differential activation of T cell cytotoxicity and cytokine release against HER2-high (SKBR-3) and HER2-low (MCF-7) cell
lines.
Figure 2 legend:
PBMCs were added at a 10:1 E:T ratio and incubated
for 42 hours, at which time cytotoxicity was quantified using the CellTiterGlo2.0 protocol. Cytokine release was detected in supernatants
diluted 1:5 in assay buffer before addition to a sensitive multiplexed bead-based assay for quantification of IL-2, IFNg, TNFa,
and IL-6 (R&D Systems/Biotechne), with detection and quantification on a MagPix system (Luminex).
ABP-102 lead candidates
are currently under evaluation with HER2-high and HER2-low expressing cell line xenograft tumor models in mice, with human PBMCs
as effector cells. Final selection of a lead molecule will be based on cumulative in vitro data and anti-tumor efficacy in the HER2 tumor
in vivo models. Expression cell lines are currently in development for production of ABP-102a, b, and c, with plans in place
for CMC activities ahead of GLP toxicology studies and clinical trials.
92
Clinical development of ABP-102
In collaboration with Celltrion,
we plan to initiate first-in-human Phase 1/2 clinical trials with ABP-102 in the first half of 2026 in HER2+ solid
tumors, including breast and gastric cancer as well as orphan drug indications.
ABP-201 for DME and Wet AMD
Our second lead product candidate, ABP-201, is
a different TetraBi antibody that simultaneously targets VEGF and ANG-2. ABP-201 binds with very high, or subnanomolar,
affinity to ANG-2 and most of the major isoforms of VEGF, including VEGF165, VEGF189, and VEGF121. Due to its TetraBi antibody
format, ABP-201 features two binding sites for each of VEGF and ANG-2, which distinguishes it from bispecific antibodies
that feature only a single binding site for each target. ABP-201 is formulated for intravitreal injection and is designed to
function as a "ligand trap," removing both VEGF and ANG-2 from the eye.
Through our majority-owned
subsidiary, AbMed Corporation, we are developing ABP-201 for potential indications in ophthalmology, including DME and Wet AMD.
DME is an eye condition brought on by diabetes in which blood vessels form abnormally and leak fluid into the macula of the eye, resulting
in blurred vision and, in extreme cases, blindness. Wet AMD is similarly a severe eye condition caused by the growth and leakage of abnormal
blood vessels under the retina and macula of the eye, causing the macula to bulge or lift up from its normally flat position, thus distorting
or destroying central vision. VEGF is a clinically validated target in both DME and Wet AMD, where Eylea and Lucentis are approved and
in widespread use. As depicted in the following chart, VEGF and ANG-2 act in concert to promote angiogenesis. In normal blood
vessel development, ANG-2 plays a role in destabilizing mature blood vessels, creating an environment in which vessel branching
can occur. VEGF then promotes the sprouting of new blood vessels. In DME and Wet AMD, however, excessive destabilization of blood vessels
by ANG-2 contributes to vessel leakage, or edema. In addition, upregulation of ANG-2 is the primary mechanism of resistance
to VEGF inhibition. We believe that effective control of angiogenesis and inhibition of vessel leakage requires simultaneous inhibition
of both pathways.
Current treatment options for DME
Although the underlying molecular
cause of DME and Wet AMD is not completely understood, both VEGF and ANG-2 play central roles in new blood vessel growth—a
hallmark common to both ocular diseases. Several biological therapies have been developed to inhibit VEGF by binding to and sequestering
the protein. The current standard-of-care includes Lucentis, a recombinant humanized monoclonal antibody fragment that binds
VEGF, and Eylea, a recombinant fusion protein containing portions of the human VEGF receptor. Another VEGF antibody is Avastin, a recombinant
human monoclonal antibody which is approved for the treatment of several cancer indications and is used off-label for the treatment
of DME and wet AMD.
Before the approval of Lucentis
for the treatment of DME in 2012, the use of intravitreal injections was less common in North America and laser photocoagulation, or the
use of light to coagulate tissue, was the primary treatment. Prior to the Lucentis DME approval, several treatments including Avastin
and Macugen (pegaptanib sodium injection) were used off-label. Macugen received FDA-approval for the treatment of
Wet AMD in 2004.
Additional products were approved
and launched in 2014, namely Eylea, Ozurdex (dexamethasone intravitreal implant), and Iluvien (fluocinolone acetonide intravitreal implant),
as well as the approval in 2022 of Vabysmo. According to estimates by Future Market Insights, intravitreal injections control a large
market share of the treatment used in DME patients. In 2021, over 94% of DME patients were utilizing anti-VEGF intravitreal injections
and implants, according to the same source.
93
Current treatment options for Wet AMD
Lucentis, Eylea, and Vabysmo
were initially FDA-approved for the treatment of Wet AMD and DME. Avastin is used off-label for the treatment of Wet
AMD. Because anti-VEGF treatments do not appear to cause regression of new blood vessels, current therapies require regular intraocular
injections, typically as often as seven times per year, and real-world studies indicate that less than 20% of patients treated with anti-VEGF
biologics improve their visual acuity by 15 or more letters.
Due to frequent injections,
anti-VEGF treatments have been associated with subretinal fibrosis, or the formation of excess connective tissue under the retina, as
well as retinal scarring in some patients. We believe a more effective therapy that requires less frequent dosing would address the deficiencies
of current therapy and be rapidly adopted as the new standard of care for the treatment of the disease.
Background and market opportunity for DME and Wet AMD
DME is a leading cause of
blindness among the working age population in most developed countries. DME is one of the major complications of diabetes and studies
show that DME patients utilize significantly higher healthcare resources than non-DME diabetic patients. The growing incidences
of diabetes across the globe should further increase the burden of DME. As of 2022, nearly 422 million people worldwide have diabetes,
and the number is expected to grow to 592 million within the next 20 years, according to Future Market Insights. North America is projected
to be the largest market in terms of value and accounted for over 60% of total market revenue in 2021, according to the same source.
AMD is a progressive disease
that results in a gradual loss of vision as people age. Approximately up to 10% of total cases of AMD represent an advanced form of the
disease called Wet AMD, which is a severe eye condition that results in blurred vision and can lead to significant vision loss or blindness
due to abnormal blood vessel formation in the eye. Although Wet AMD represents only 10% of AMD, it is responsible for 90% of AMD-related severe
vision loss. Wet AMD is a leading cause of vision loss, with approximately 200,000 cases of Wet AMD diagnosed per year in North America,
according to ResearchAndMarkets.com.
In 2022, Eylea and Lucentis,
the leading approved biologics for the treatment of DME and Wet AMD accounted for over $10.4 billion in worldwide sales according
to company filings. It is important to note that the first biosimilar for Lucentis was approved in the third quarter of 2022.
Potential ABP-201 Competitive Advantages
Unlike Eylea and Lucentis, ABP-201 seeks
to inhibit both VEGF and ANG-2. Unlike Vabysmo, ABP-201 has two binding sites for VEGF and ANG-2, designed
to more effectively trap each ligand. ABP-201 also has a longer half-life in the eye than Eylea, which contributes to pharmacological
durability.
Clinical Development Plan for Wet AMD
We plan to conduct a Phase
1, multiple-ascending dose evaluation of the safety and initial efficacy of ABP-201 in patients with wet age-related macular
degeneration (Wet AMD). Following the identification of the maximum tolerated dose (MTD) or the safety and tolerability of the maximum
administered dose (MAD), a larger randomized phase 2 study is planned.
94
Potential benefits of ABP-201 in ophthalmology
One way to co-inhibit VEGF
and ANG-2 is to add an ANG-2 inhibitor to an approved VEGF inhibitor. The shortcoming of this approach is that the
two agents are not physically linked and as a result will accumulate differently and be cleared from the eye at different rates. It is
therefore difficult to ensure that both targets are inhibited in the same place at the same time. In contrast to this dual agent approach,
other investigational agents, including ABP-201, use a single-agent dual-targeting antibody to ensure that both targets are
engaged at the same time. Clinical trial results with Vabysmo, a bispecific antibody co-targeting VEGF and ANG-2, showed
a dose-dependent improvement in best-corrected visual acuity relative to Lucentis, providing strong support for this approach. Importantly,
our single agent approach may have regulatory advantages over the dual agent approach given that the necessary efficacy endpoints for
approval could include non-inferiority in contrast with superiority to current standard-of-care. The dosing regimens
of current DME and AMD drugs, specifically Lucentis and Eylea, are characterized by relatively frequent injections, initially every month
followed by every other month. The frequency of injection is determined by a combination of the potency of the drug and its clearance
rate from the eye. Large molecules generally clear slower than smaller molecules, and ABP-201 is approximately twice the size
of Eylea and approximately four times the size of Lucentis. ABP-201 also has a higher binding capacity than either Eylea or
Lucentis, with two binding sites for VEGF and two binding sites for ANG-2. As such, we believe that ABP-201 will require
less frequent dosing, providing a significant advantage in the commercial setting. In addition, as increased signaling by ANG-2 in
response to anti-VEGF therapy is one of the primary mechanisms of resistance to VEGF inhibitors, we anticipate that ABP-201 will
not suffer from drug resistance to the same extent as drugs that target VEGF alone.
In a rat laser-induced choroidal
neovascularization model, ABP-201 administered intravitreally resulted in comparable reductions in vascular leakage and vascular
lesion volume as Eylea. In this model, a laser is used to ablate blood vessels in the choroid (the vascular layer underlying the retina).
The area ablated then heals (becomes revascularized) spontaneously by the formation of neovascular "lesions." Anti-angiogenic
agents can then be assessed by how much they can delay this healing, as measured by how well they can reduce vascular leakage and neovascular
lesion size.

Study with Intravitreally-injected Abpro Test Article ABP201 in Brown Norway Rats, December 20, 2023.
Pharmacological durability
is desired in agents administered intravitreally injection given the risk of injection-associated inflammation and the uncomfortable nature
of the injection. A major contributing factor to pharmacological durability is half-life.
Administration of ABP-201 resulted
in significantly reduced vascular leakage and neovascular lesion volume compared to a vehicle control and comparable to Eylea.
A major concern for all intravitreally-administered
agents is the potential for inflammation, either caused by the agent or the injection procedure. Given that intravitreal injection itself
is associated with the potential for ocular inflammation among other toxicities, increasing the pharmacological durability of such agents
is critical in minimizing the potential for such toxicities. As such, ABP-201 is engineered to both maximize half-life in the
eye and to reduce any Fc receptor-mediated inflammatory responses. In preclinical PK models, ABP-201 displays a favorable ocular
half-life compared to Faricimab (RG7716/Vabysmo) or Eylea (aflibercept). In addition, ABP-201 is well tolerated in rabbit toxicity
studies.

C Study Following Intravitreal (IVT) Delivery of a Novel Compound in Rabbit, April 27, 2021.
Administration of ABP-201 results
in intraocular pressure (IOP) increases comparable to vehicle control (left panel above). Additionally, ocular examinations (OE) to evaluate
ocular surface morphology, anterior segment and posterior segment inflammation, cataract formation, and retinal changes were performed.
The OE scores can range from 0, indicating no abnormalities, to 48, indicating a maximum number of maximally severe abnormalities. Other
than a mild increase in OE score of 5 at day 1 post-injection, which returned to 0 for the duration of the study, the OE scores were identical
to that of the vehicle control. Taken together, the lack of increases in IOP and OE scores suggests that ABP-201 is well-tolerated.
The vitreous humor in the
human eye is approximately 4 ml. Given the small volume of the vitreous humor, agents injected intravitreally must be able to be sufficiently
concentrated so as to be injected in small enough volumes to not produce significant increases in IOP. Excessive increases in IOP resulting
in ocular hypertension is associated with a variety of adverse events such as ocular inflammation, glaucoma, and retinal detachment. As
such, ABP-201 formulation efforts have achieved a 100 mg/ml concentration with acceptable biophysical characteristics, especially
viscosity. We believe that this concentration will allow us to administer efficacious dose levels of ABP-201 in small enough
volumes to avoid toxic increases in IOP. Even so, preliminary evidence suggests that higher concentrations are achievable.

Other programs
Additional TetraBi antibody T-cell engagers
Building on the CD3-directed TetraBi
antibody format of ABP-102, we are using our
DiversImmune
®
and
MultiMab
TM
platforms
to develop a broad pipeline of immuno-oncology agents that target highly expressed antigens on a diverse range of tumor types.
ABP-110
ABP-110 is a TetraBi
antibody targeting GPC3 and CD3 for the potential treatment of hepatocellular carcinoma, or HCC, the major form of liver cancer. ABP-110 is
designed to bind bivalently to GPC3 on HCC cells and CD3 on cytotoxic T cells, bringing these two cell types into close proximity and
triggering sustained T-cell activation and tumor cell killing. GPC3 is an onco-fetal antigen that is only expressed during fetal
development and on HCC cells, making it an ideal tumor antigen target. GPC3 expression is also prognostic of poor overall survival
in HCC, suggesting that ABP-110 may be most effective in the patients at highest risk and most in need of novel therapeutic
interventions. Targeting this patient population may provide for a relatively rapid path to approval given the unmet medical need in HCC.
Source: Abpro internal data.
We have generated three lead
candidates that have displayed potent T cell-mediated killing of GPC3-positive tumor cells. The next steps are to assess the pharmacokinetics
and in vivo efficacy in preclinical GPC3-positive tumor models. We expect to initiate clinical trials for ABP-110 in the first
half of 2027. According to SNS Insider, the global liver cancer therapeutics market is projected to reach $12.9 billion by 2030.
ABP-150
ABP-150 is a TetraBi
antibody targeting claudin 18.2 and CD3 for the potential treatment of gastric cancers. Like our other T cell engagers, ABP-150 is
designed to bind bivalently to claudin 18.2 on gastric cancer cells and to CD3 on cytotoxic T cells, leading to T cell-mediated killing
of gastric tumor cells. Claudin 18.2 is exclusively expressed on gastric tissue, a tissue with a high physiological turnover rate, making
it tolerant of even moderate acute toxicity without unacceptable or chronic toxic effects.

Preclinically, ABP-150 shows
potent killing in in vitro T cell-mediated killing assays. In both mouse syngeneic tumor models using human CD3-transgenic mice
and human tumor xenograft models using human peripheral blood mononuclear cells as a source of T cells, ABP-150 shows potent
efficacy. As ABP-150 cross-reacts with mouse claudin 18.2, but not mouse CD3, we demonstrated in a human CD3-transgenic mouse
toxicity model that ABP-150 is well tolerated, with little impact on body weight, appetite (food consumption) or body temperature. IL-6, a
key cytokine for the initiation of cytokine release syndrome, saw little increase over vehicle (placebo) control. The next steps are to
evaluate toxicity in a non-human primate model. We expect to initiate clinical trials for ABP-150 in the first half
of 2027. According to Data Bridge Market Research, the global gastric cancer market is projected to reach $13.1 billion by 2029.

SARS-CoV-2 neutralizing antibody program
As of October 2023, according
to data published by the Word Health Organization, the COVID pandemic has resulted in over 771 million confirmed cases and over 6 million
deaths have been reported globally. While vaccination efforts have made tremendous strides in bringing the pandemic under control, vaccination
is contraindicated in some individuals, such as the immunocompromised. For these patients, there are no currently available prophylactic
therapies. The only therapies available are Nirmatrelvir/ritonavir, molnupiravir, and remdesivir. While these are effective therapies,
their toxicities preclude them from being used as prophylactics. Monoclonal antibodies are ideal molecules to serve as prophylactic therapies
as they can effectively neutralize the SARS-CoV-2 virus and have a proven safety profile and can be engineered to extend their
half-lives. However, all antibody therapies and prophylactics to date have become ineffective due to SARS-CoV-2 viral mutation.
In response to the global pandemic, Abpro sought to develop COVID antibodies targeting highly conserved (resistant to mutation) areas
of the virus with highly potent neutralizing antibodies engineered to have extended half-lives to allow for dosing intervals of greater
than six months, through collaborations with third parties in the form of in-license agreements. Several candidate molecules were evaluated
through different stages of development. The most advanced molecule was developed through GMP manufacturing and evaluated in a clinical
trial. However, the clinical trial was not successful. Since the health threats from the COVID pandemic have now decreased, Abpro is not
planning to focus on this area at this time.
Our Collaborations
We are developing next generation
antibodies both independently and in collaboration with leading global biopharmaceutical companies and non-profit and government
research institutions. We in-license some of the technology that we use in the ABP-110 and ABP-201 molecules.
In-licensing agreements
We in-license rights
to intellectual property relevant or potentially relevant to our development and commercialization plans in the ordinary course of business.
We have in-licensed rights to certain intellectual property from the National Institutes of Health, or NIH, and from AstraZeneca
(formerly Medimmune).
National Institutes of Health—ABP-110
In September 2017 we entered
into a patent license agreement effective as of August 1, 2017 with the National Cancer Institute, or NCI, a division of the NIH,
pursuant to which we received an exclusive, worldwide license, with the right to sublicense (subject to certain conditions), under certain
patent rights to make, have made, use, have used, sell, have sold, offer to sell and import products covered by the licensed patents in
the field of using certain monoclonal antibodies as monospecific or bispecific antibodies for the treatment of liver cancer. The license
was amended in May 2020 and October 2023 and the field of use was narrowed to the development and commercialization of a bispecific antibody
for the treatment of GPC-3 expressing liver cancer using a particular moiety for targeting GPC3 and the timeline for development
and commercialization was extended. We agreed to pay NCI a $25,000 issuance fee in connection with the October 2023 amendment to the patent
license agreement. Under the amended patent license agreement, we will be obligated to pay a $25,000 minimum annual royalty, creditable
against any earned royalties, and to pay royalties of a single digit percentage based on net sales of licensed products. We also agreed
to pay up to an aggregate of approximately $16.0 million of benchmark royalties, which are payable upon achieving certain clinical,
regulatory and commercial milestones. We also agreed to pay sublicense royalties ranging from a mid-single digit percentage
to a low-double digit percentage based on the fair value of the consideration we receive from any sublicensees. The royalty
term expires on a licensed patent-to-licensed patent and country-by-country basis upon the earlier of (i) the
date an application in the licensed patents has been abandoned, (ii) the date a licensed patent expires or (iii) the date a
licensed patent has been held invalid or unenforceable by a court of competent jurisdiction or administrative agency. Unless earlier terminated,
our agreement with NCI will expire upon expiration of all licensed patent rights. NCI may terminate our agreement upon the occurrence
of specified bankruptcy events for us or if we are in material default or breach of the agreement and do not cure within a specified notice
and cure period. NCI may terminate the agreement if necessary to meet the public use requirement specified by federal regulations and
we are not reasonably satisfying such requirements. We may also terminate the agreement as to any licenses in any country or territory
upon 60 days written notice. Upon expiration or termination of the agreement, we are required to return to NCI or destroy all licensed
products and other materials in the licensed patents.
99
Our license is subject to
the reserved rights of NCI and the U.S. government. Additionally, all licensed products used or sold in the United States are required
to be manufactured substantially within the United States.
AstraZeneca
In August 2016, we entered
into a collaboration and license agreement through our majority-owned subsidiary, AbMed Corporation, or AbMed, and MedImmune (now AstraZeneca),
pursuant to which MedImmune granted AbMed an exclusive, worldwide, royalty-bearing, sublicensable (subject to certain conditions) license
under specified patent rights and know-how to make, use, sell certain of its proprietary ANG-2/VEGF-H1RK bispecific
antibodies. We hold 82% of the capital stock of AbMed, and MedImmune (now AstraZeneca) holds the remainder. We are responsible for the
operational activities of AbMed, and bear all costs necessary to operate AbMed. Our chief executive officer, Ian Chan, is also the chief
executive officer of AbMed and oversees the business strategy and operations of AbMed.
Under the agreement, AbMed
agreed to pay milestone and royalty payments, including up to $244.0 million in milestone payments, which are comprised of $14.0 million
upon meeting certain clinical development milestones, $80.0 million upon achieving certain regulatory events and $150.0 million
upon meeting certain worldwide commercial sales thresholds; and tiered high-single digit to low teens percentage royalties based on annualized
net sales of each product commercialized from our collaboration on a country-by-country basis.
Unless earlier terminated
in accordance with its terms, the agreement with AbMed and AstraZeneca remains in effect on a country-by-country basis until
the later of (i) the expiration of patent claims that cover the licensed product in a country, (ii) 10 years after the first commercial
sale of a licensed product in a country, and (iii) the expiration of regulatory exclusivity for a licensed product in a country.
AbMed could be required to redeem AstraZeneca's equity stake in certain circumstances. We are in breach of the terms of our license
agreement with AstraZeneca. See "Risk Factors — Risks Relating to Abpro's Business and Industry — Through our
AbMed subsidiary, we have in-licensed certain intellectual property rights relating to ABP-201 from MedImmune Limited,
or MedImmune (now AstraZeneca), and are in breach of the terms of our license agreement with MedImmune/AstraZeneca." AstraZeneca
may terminate our agreement on the basis of this breach, or upon the occurrence of specified bankruptcy events for us or if we are in
material default or breach of the agreement and do not cure within a specified notice and cure period. We may also terminate the agreement
upon 90 days written notice.
In November 2016, we entered
into an amendment to this agreement pursuant to which Medimmune granted us a non-exclusive sublicense to certain additional
intellectual property rights held by Medimmune under an agreement with EMD Millipore Corporation and the know-how included under
the agreement was amended. In August 2017, we entered into a side letter with MedImmune to clarify our agreement regarding the timing
of our required contribution to AbMed and the issuance of MedImmune's equity stake. The agreement was further amended in November
2017, March 2018 and December 2019 to modify the dates for the achievement of certain development and commercialization milestones and
AbMed agreed to use commercially reasonable efforts to reach these development and commercialization milestones within specified timeframes.
Partnerships
Celltrion
ABP-102 is being developed
and commercialized through a worldwide strategic partnership with Celltrion Inc. ("Celltrion") (KRX:068270), a leading Korean
biopharmaceutical company headquartered in Incheon, South Korea, under a Collaboration Agreement entered into in September 2022 and amended
in October 2024. We received an initial milestone payment of $2.0 million from Celltrion in connection with this agreement. We also
received an equity investment in our Series F preferred stock of $2.0 million from Celltrion.
100
We agreed to form a joint
steering committee to oversee the collaboration that includes representatives from both our company and Celltrion. Celltrion agreed to
use commercially reasonable efforts to develop and commercialize a licensed product, including the achievement of certain milestones by
certain dates.
Under the Collaboration Agreement,
our company is responsible for certain in vitro pre-clinical work, and Celltrion is responsible for in vivo preclinical work,
CMC, clinical development and commercialization on a worldwide basis. All costs and expenses for future development and commercialization
of the molecule are required to be paid initially by Celltrion. The proceeds from commercialization are subject to a 50/50 profit split.
Amounts that may be paid by third party collaborators, for example upfronts, milestones and/or royalty payments from territorial commercialization
partners, are also subject to a 50/50 split. Following commercial approval of ABP-102, we have agreed to reimburse Celltrion
250% of its direct and certain indirect costs and expenses incurred through first commercial sale. Celltrion is entitled to offset amounts
otherwise due to us under the agreement until our share of these costs has been paid back; provided that we are entitled to a minimum
25% of profit from commercial sales and from third party collaborators regardless of the amount of unreimbursed development costs outstanding
(and then 50% once the reimbursement has been made in full). In addition, we are entitled to up to over $1.75 billion in development
and sales milestones. We are responsible for world-wide patent prosecution, with Celltrion reimbursing 50% of our out-of-pocket costs.
Unless earlier terminated,
our agreement with Celltrion will remain in effect so long as ABP-102 is being developed or commercialized anywhere in the world.
Either party may terminate our agreement upon the occurrence of specified bankruptcy events relating to the other party. We may terminate
the agreement if Celltrion is in material default or breach of the agreement and does not cure within a specified notice and cure period.
Celltrion may also terminate the agreement upon 180 days written notice.
Abpro Bio
ABP-201 is being developed
and commercialized through a territorial partnership with Abpro Bio International, Inc. ("Abpro Bio"), a subsidiary of Abpro
Bio Co. Ltd (KOSDAQ:195990), a company formerly named Ugint Co Ltd. with diversified holdings in precision machine tools, equipment and
biotechnology headquartered in Daegu, South Korea granting Abpro Bio exclusive development and commercialization rights under a Collaboration
and License agreement entered into in January 2020, in the People's Republic of China, Japan, South Korea, Southeast Asia (which
for the purposes hereof means Philippines, Indonesia, Taiwan, Pakistan, India, Vietnam, Laos, Cambodia, Thailand, Myanmar and West Malaysia),
the Middle East (which for the purposes hereof means Bahrain, Cyprus, Egypt, Iraq, Israel, Jordan, Kuwait, Lebanon, Northern Cyprus, Oman,
Palestine, Qatar, Saudi Arabia, Syria, Turkey, United Arab Emirates and Yemen), and the Commonwealth of Independent States (CIS) (which
for the purposes hereof means Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Moldova, Russia,
Tajikistan, Turkmenistan, Ukraine and Uzbekistan).
Our company, through our majority
owned subsidiary, AbMed Corporation received an equity investment of $30 million from Abpro Bio in connection with this agreement.
Under the Collaboration and License Agreement, we granted Abpro Bio an exclusive, royalty-bearing sublicenseable (subject to certain restrictions)
license under specified patent rights and know-how to make, use, sell certain proprietary ANG-2/VEGF-H1RK bispecific
antibodies in China, Japan, South Korea and certain other countries in South East Asia, the Middle East and the Commonwealth of Independent
States (CIS).
We agreed to form a joint
steering committee to oversee the collaboration that includes representatives from both AbMed Corporation and Abpro Bio. Abpro Bio agreed
to use commercially reasonable efforts to develop and commercialize a licensed product, including the achievement of certain milestones
by certain dates. Under the agreement, Abpro Bio agreed to pay us a double-digit percentage royalty in the low teens, tiered based on
cumulative net sales by Abpro Bio, its affiliates or sublicensees beginning with the first commercial sale of a licensed product in its
territory. We are also entitled to payments totaling approximately $540 million subject to the satisfaction of certain development
and sales milestones. We are responsible for patent prosecution and Abpro Bio has agreed to reimburse us for patent costs in its licensed
territory. Unless earlier terminated in accordance with its terms, the agreement with Abpro Bio remains in effect on a country-by-country basis
until the later of (i) the expiration of patent claims that cover the licensed product in a country, (ii) 10 years after the first
commercial sale of a licensed product in a country, and (iii) the expiration of regulatory exclusivity for a licensed product in
a country. We may terminate the agreement upon the occurrence of specified bankruptcy events relating to Abpro Bio or if Abpro Bio is
in material default or breach of the agreement and does not cure within a specified notice and cure period. Abpro Bio may also terminate
the agreement upon 90 days written notice.
101
NJCTTQ
We entered into a collaboration
agreement in January 2019 with NJCTTQ, a pharmaceutical company specializing in research and development, production and commercialization
of drugs for cardiovascular diseases, tumors, perioperative care, gastrointestinal disorders and urologic diseases headquartered in Nanjing,
China.
We agreed to form a joint
steering committee to oversee the collaboration that includes representatives from both our company and NJCTTQ. NJCTTQ paid a technology
access fee to us and agreed to reimburse our preclinical research and development costs for the selected program up to CMC stage. Under
the agreement, CMC development costs and GLP toxicology costs are shared equally, with each party thereafter being responsible for its
own development and commercialization costs in its territory, with the NJCTTQ territory being China and Thailand and our company retaining
rights to the rest of the world. The parties agreed to pay reciprocal royalties, with each of them paying the other party low single-digit
royalties, tiered based on net sales per calendar year in its territory. In addition, NJCTTQ agreed to pay us milestones based on commercial
approval and sales in its territory of up to $405 million and we agreed to pay NJCTTQ a milestone based on commercial approval in
our territory of $5 million. ABP-150 is being developed under this agreement.
Unless earlier terminated
in accordance with its terms, the initial term of this agreement is five years from its effective date, with automatic renewals for an
additional five years unless objected to in writing by a party at least six months prior to expiration of the initial term. If no joint
development program gets to clinical stage within the first five years of the collaboration, then the agreement by its terms will not
be renewed after expiration. Either party has the right to terminate in the case of material default or breach of the agreement by the
other party not cured within a specified period, in which case the parties' rights and obligations under the agreement are terminated,
except for rights accrued prior to termination and customary survival clauses. If the agreement is terminated other than for cause, the
territorial rights and payment obligations of each party relating to the development and commercialization of a licensed product in its
territory survive such termination.
The agreement remains unrenewed
at this time after the expiration of its initial term. However, notwithstanding the agreement's expiration, the low single-digit
royalties and the $5 million milestone payable to NJCTTQ based on commercial approval in our territory, as described above, will continue
to apply.
Manufacturing
We produce small-scale quantities
of our antibodies and reagents for characterization,
in vitro
and
in vivo
preclinical assessment of
product candidates at our Woburn, Massachusetts research and development facilities. We do not have, and we do not currently plan to acquire
or develop, the infrastructure, facilities or capabilities to manufacture current Good Manufacturing Practices, or cGMP, bulk drug substance
or filled drug product for use in human clinical trials. We intend to utilize third-party manufacturers such as contract manufacturing
organizations, or CMOs, to produce, test and release cGMP bulk drug substance and drug product for our planned clinical trials. We expect
to continue to rely on such third parties to manufacture clinical trial material for the foreseeable future.
Competition
The biotechnology and biopharmaceutical
industries, and the immuno-oncology and ophthalmology subsectors, are characterized by rapid evolution of technologies, fierce competition
and strong defense of intellectual property. Any product candidates that we successfully develop and commercialize will have to compete
with existing therapies and new therapies that may become available in the future. While we believe that our proprietary
DiversImmune
®
and
MultiMab
TM
platforms,
along with our scientific expertise in the field of biologics and immuno-oncology, provide us with competitive advantages, a wide variety
of institutions, including large biopharmaceutical companies, specialty biotechnology companies, academic research departments and public
and private research institutions, are actively developing potentially competitive products and technologies. Our competitors generally
fall within the following categories:
●
Antibody developers
. Such as Adimab Inc., AnaptysBio, Inc., Bristol-Myers Squibb Company, Glenmark Pharmaceuticals, Inc., Jounce Therapeutics, Inc., MorphoSys AG, Precigen, Inc. and Regeneron Pharmaceuticals, Inc.
102
●
Immune-based treatments for cancer, such as CAR T and TCR therapies
. Such as Bellicum Pharmaceuticals, Inc., Bluebird bio, Inc., Bristol-Myers Squibb Company, Cellectis S.A., Gilead Sciences, Inc., Novartis AG, Precigen, Inc., AstraZeneca and Genentech, Inc. (a member of the Roche Group, or Genentech/Roche).
●
Treatments for Ophthalmology related indications
. Such as Allergan plc, Genentech/Roche, Novartis International AG, and Regeneron Pharmaceuticals, Inc.
Many of our competitors, either
alone or with strategic partners, have substantially greater financial, technical and human resources than we do. Accordingly, our competitors
may be more successful than us in obtaining approval for treatments and achieving widespread market acceptance, rendering our treatments
obsolete or non-competitive.
Accelerated merger and acquisition
activity in the biotechnology and pharmaceutical industries may result in even more resources being concentrated among a smaller number
of our competitors. These companies also compete with us in recruiting and retaining qualified scientific and management personnel, establishing
clinical study sites and patient registration for clinical studies and acquiring technologies complementary to, or necessary for, our
programs. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements
with large and established companies.
Our commercial opportunity
could be substantially limited in the event that our competitors develop and commercialize products that are more effective, safer, less
toxic, more convenient or less expensive than our comparable products. Competitors may also obtain regulatory approvals before us, resulting
in our competitors building a strong market position in advance of our products' entry, if any. We believe the factors determining
the success of our product pipeline will be the efficacy, safety and convenience of our product candidates.
Intellectual Property
Our commercial success will
depend significantly on our and our licensors' ability to obtain and maintain patent and other proprietary protection for our product
candidates and the other technology, inventions and improvements we consider important to our business, defend any patents we obtain or in-license, preserve
the confidentiality of our trade secrets and operate without infringing the patents and proprietary rights of third parties. Our policy
is to seek to protect our proprietary and intellectual property position by, among other methods, filing and in-licensing U.S.,
international (under Patent Cooperation Treaty, or PCT) and foreign patent applications related to our product candidates and other proprietary
technology, inventions and improvements that we consider are important to the development and implementation of our business. We also
rely on trade secrets, know-how and continuing technological innovation to develop and maintain our proprietary and intellectual
property position.
ABP-102
As of December 31, 2023,
we own two patent families that cover compositions of matter, methods of use, and methods of manufacture for our ABP-102 product
candidate, a bispecific HER2 and CD3 binding antibody. The first and second families each consist of one pending international Patent
Cooperation Treaty ("PCT") patent application. Any patents resulting from these applications would be expected to expire in
2042, excluding any patent term adjustments and/or extensions.
ABP-110
As of December 31, 2023,
we have licensed one patent family from the US Department of Health and Human Services that covers compositions of matter, methods of
use, and methods of manufacture related to our ABP-110 product candidate, a tetravalent bispecific glypican-3 (GPC3)
and CD3 binding antibody. This family includes one issued patent in the United States and issued patents in China, Japan, South Korea,
and Singapore. The patents in this family are expected to expire in 2033, excluding any patent term adjustments and/or extensions.
103
ABP-150
As of December 31, 2023,
we own one patent family that covers compositions of matter, methods of use, and methods of manufacture for our ABP-150 product
candidate, a bispecific Claudin18.2 and CD3 binding antibody. This family includes applications that are currently pending in the United
States, China, Europe, Japan, South Korea, and Thailand. The patents in this family are expected to expire in 2041, excluding any patent
term adjustments and/or extensions.
ABP-201
As of December 31, 2023,
we own one patent family that covers compositions of matter, methods of use, and methods of manufacture for our ABP-201 product
candidate, which binds to both angiopoietin-2, or ANG-2, and vascular endothelial growth factor, or VEGF. This family
includes a pending international PCT application and pending applications in the United States, China, Europe, Japan, and South Korea.
Any patents resulting from that application would be expected to expire in 2042, excluding any patent term adjustments and/or extensions.
Through our majority-owned
subsidiary AbMed Corporation, we have also exclusively licensed from MedImmune/AstraZeneca certain intellectual property originally entered
in connection with ABP-200, which we are no longer developing. As of December 31, 2023, we have licensed three patent families from
MedImmune/AstraZeneca comprised of pending and/or issued U.S. and foreign patents and applications. The patents in these families are
not expected to cover ABP-201 and/or are expected to expire before commercialization of ABP-201, excluding any patent term adjustments
and/or extensions. We believe that we do not need the intellectual property licensed under this agreement for the development and eventual
commercialization of ABP-201 or any of our other programs.
As of December 31, 2023,
one of these licensed patent families includes three issued U.S. patents, and issued patents in Australia, Brazil, China, Hong Kong, Japan,
Mexico, Russia, South Korea, as well as pending applications in Europe and India. The patents in this family are expected to expire in
2025, excluding any patent term adjustments and/or extensions.
As of December 31, 2023,
the second family of these licensed patent families includes two issued patents in the United States and issued patents in Australia,
China, Japan, and South Korea, as well as pending applications in Canada, Europe, Hong Kong, and Israel. Any patents resulting from that
application would be expected to expire in 2037, excluding any patent term adjustments and/or extensions.
As of December 31, 2023,
the third family of these licensed patents includes two issued patents in the United States, and issued patents in Australia, China, Europe,
Hong Kong, Japan, and South Korea, as well as pending applications in Australia, Canada, Europe, Hong Kong, and Israel. Any patents resulting
from that application would be expected to expire in 2037, excluding any patent term adjustments and/or extensions.
104
Regulatory framework
The term of individual patents
depends upon the legal term for patents in the countries in which they are obtained. In most countries, including the United States, the
patent term is 20 years from the earliest filing date of a non-provisional patent application. In the United States, a
patent's term may be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the USPTO in
examining and granting a patent, or may be shortened if a patent is terminally disclaimed over an earlier filed co-owned patent.
The term of a patent that covers a drug or biological product may also be eligible for patent term extension when FDA approval is granted,
provided statutory and regulatory requirements are met. However, as to the FDA component, the restoration period cannot be longer than
five years and the total patent term including the restoration period must not exceed 14 years following the FDA approval. Additionally,
only one patent may be extended, and only those claims covering the approved drug, a method for using it, or a method for manufacturing
it may be extended. The duration of foreign patents varies in accordance with provisions of applicable local law, but typically is also
20 years from the earliest effective filing date. In the future, if and when our product candidates receive approval by the FDA or foreign
regulatory authorities, we expect to apply for patent term extensions on issued patents covering those products, depending upon the length
of the clinical studies for each product and other factors. There can be no assurance that any of our pending patent applications will
issue or that we will benefit from any patent term extension or favorable adjustments to the terms of any of our patents. The FDA and
the USPTO in the United States, and any equivalent regulatory authority in other countries, may not agree with our assessment of whether
such extensions are available, and may refuse to grant extensions to our patents, or may grant more limited extensions than we request.
An extension may also not be granted because of, for example, a failure to exercise due diligence during the testing phase or regulatory
review process, failing to apply within applicable deadlines, failing to apply prior to the expiration of relevant patents, or otherwise
failing to satisfy applicable requirements. The actual protection afforded by a patent varies on a product-by-product basis,
from country-to-country, and depends upon many factors, including the type of patent, the scope of its coverage, the availability
of regulatory-related extensions, the availability of legal remedies in a particular country, and the validity and enforceability of the
patent. In addition to patents, we rely upon unpatented trade secrets and know-how and continuing technological innovation to
develop and maintain our competitive position. We seek to protect our proprietary information, in part, by executing confidentiality agreements
with our collaborators and scientific advisors, and non-competition, non-solicitation, confidentiality and invention assignment
agreements with our employees and consultants. We also have or intend to implement executed agreements requiring assignment of inventions
with selected scientific advisors and collaborators. These confidentiality agreements are designed to protect our proprietary information
and, in the case of invention assignment agreements, to grant us ownership of technologies that are developed through a relationship with
a third party. However, these agreements may be breached, and we may not have adequate remedies for any breach, with a third party. In
addition, our trade secrets may otherwise become known or be independently discovered by competitors. To the extent that our commercial
partners, collaborators, employees and consultants use intellectual property owned by others in their work for use, disputes may arise
as to the rights in related or resulting know-how and inventions.
We also seek to preserve the
integrity and confidentiality of our proprietary technology and processes by maintaining physical security of our premises and physical
and electronic security of our information technology systems. Although we have confidence in these individuals, organizations, and systems,
agreements or security measures may be breached and we may not have adequate remedies for any breach. To the extent that our employees,
contractors, consultants, collaborators, and advisors use intellectual property owned by others in their work for us, disputes may arise
as to the rights in related or resulting know-how and inventions. For more information regarding the risks related to our intellectual
property, proprietary technology, inventions, improvements, platforms and product candidates, please see the section entitled "
Risk
Factors — Risks Related to Intellectual Property.
"
Government regulation and product approval
Governmental authorities in
the United States, at the federal, state, and local level, and other countries extensively regulate, among other things, the research,
development, testing, manufacture, labeling, packaging, promotion, storage, advertising, distribution, marketing, and export and import
of products such as those we are developing. Our therapeutic product candidates must be approved by the FDA through the Biologics License
Application, or BLA, process before they may be legally marketed in the United States and will be subject to similar requirements in other
countries prior to marketing in those countries. The process of obtaining regulatory approvals and the subsequent compliance with applicable
federal, state, local, and foreign statutes and regulations require the expenditure of substantial time and financial resources.
U.S. Government regulation
In the United States, the
FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and, in the case of therapeutic biologics, the Public Health
Service Act, or PHSA, and implementing regulations of each. Failure to comply with the applicable U.S. requirements at any time during
the product development or approval process, or after approval, may subject an applicant to administrative or judicial sanctions, any
of which could have a material adverse effect on us. These sanctions could include:
●
refusal to approve pending applications;
●
withdrawal of an approval;
105
●
imposition of a clinical hold;
●
warning or untitled letters;
●
seizures or administrative detention of product;
●
total or partial suspension of production or distribution; or
●
injunctions, fines, disgorgement, or civil or criminal penalties.
BLA approval process
The process required by the
FDA before a therapeutic biologic may be marketed in the United States generally involves the following:
●
completion of nonclinical laboratory tests, animal studies and formulation studies conducted according to Good Laboratory Practices, or GLPs, and other applicable regulations;
●
submission to the FDA of an IND, which must become effective before human clinical trials may begin, and applicable institutional review boards (IRBs)/ ethics committee approvals;
●
performance of adequate and well-controlled human clinical trials according to Good Clinical Practices, or GCPs, to establish the safety and efficacy of the product candidate for its intended use;
●
submission to the FDA of a BLA;
●
satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the product candidate is produced to assess readiness for commercial manufacturing and conformance to the manufacturing-related elements of the application, to conduct a data integrity audit, and to assess compliance with cGMPs to assure that the facilities, methods, and controls are adequate to preserve the product candidate's identity, strength, quality, and purity;
●
satisfactory completion of an FDA inspection at selected clinical research sites, the contract research organization if the monitoring of the study was outsourced, and/or inspection of the Sponsor organization to assess GCP compliance may also be required and;
●
FDA review and approval of the BLA.
Once a biopharmaceutical candidate
is identified for development, it enters the preclinical or nonclinical testing stage. Nonclinical tests include laboratory evaluations
of product chemistry, toxicity, and formulation, as well as animal studies. An IND sponsor must submit the results of the nonclinical
tests, together with manufacturing information and analytical data, to the FDA as part of the IND. Some nonclinical testing may continue
even after the IND is submitted. In addition to including the results of the nonclinical studies, the IND will also include a protocol
detailing, among other things, the objectives of the clinical trial, the parameters to be used in monitoring safety, and the effectiveness
criteria to be evaluated if the first phase lends itself to an efficacy determination. The IND automatically becomes effective 30 days
after receipt by the FDA, unless the FDA, within the 30-day time period, places the IND on clinical hold. In such a case, the
IND sponsor and the FDA must resolve any outstanding concerns before clinical trials can begin. A clinical hold may occur at any time
during the life of an IND and may affect one or more specific studies or all studies conducted under the IND.
106
All clinical trials must be
conducted under the supervision of one or more qualified investigators in accordance with GCPs. They must be conducted under protocols
detailing the objectives of the trial, dosing procedures, research subject selection and exclusion criteria, and the safety and effectiveness
criteria to be evaluated. Each protocol, and any subsequent material amendment to the protocol, must be submitted to the FDA as part of
the IND, and progress reports detailing the status of the clinical trials must be submitted to the FDA annually. Sponsors also must report
to the FDA serious and unexpected suspected adverse reactions in a timely manner, any clinically important increase in the rate of a serious
suspected adverse reaction over that listed in the protocol or investigation brochure or any findings from other studies or animal or
in
vitro
testing that suggest a significant risk in humans exposed to the product candidate. An IRB at each institution participating
in the clinical trial must review and approve the protocol before a clinical trial commences at that institution and must also approve
the information regarding the trial and the informed consent form that must be provided to each research subject or the subject's
legal representative, monitor the study until completed and otherwise comply with IRB regulations. There are also requirements governing
the reporting of ongoing clinical trials and completed clinical trial results to public registries.
Human clinical trials are
typically conducted in three sequential phases that may overlap or be combined.
●
Phase 1
—The product candidate is initially introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution, and elimination. In the case of some therapeutic candidates for severe or life-threatening diseases, such as cancer, especially when the product candidate may be inherently too toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.
●
Phase 2
—Clinical trials are performed on a limited patient population intended to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage.
●
Phase 3
—Clinical trials are undertaken to further evaluate dosage, clinical efficacy, and safety in an expanded patient population at geographically dispersed clinical study sites. These studies are intended to establish the overall risk-benefit ratio of the product and provide an adequate basis for product labeling.
A pivotal study is a clinical
study that adequately meets regulatory agency requirements for the evaluation of a product candidate's efficacy and safety such
that it can be used to justify the approval of the product. Generally, pivotal studies are also Phase 3 studies but may be Phase 2 studies
if the trial design provides a reliable assessment of clinical benefit, particularly in situations where there is an unmet medical need.
Human clinical trials are inherently uncertain, and Phase 1, Phase 2, and Phase 3 testing may not be successfully completed. The FDA or
the sponsor may suspend a clinical trial at any time for a variety of reasons, including a finding that the research subjects or patients
are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution
if the clinical trial is not being conducted in accordance with the IRB's requirements or if the product candidate has been associated
with unexpected serious harm to patients.
During the development of
a new product candidate, sponsors are given opportunities to meet with the FDA at certain points; specifically, prior to the submission
of an IND, at the end of Phase 2 and before a BLA or New Drug Application, or NDA, is submitted. Meetings at other times may be requested.
These meetings can provide an opportunity for the sponsor to share information about the data gathered to date and for the FDA to provide
advice on the next phase of development.
Post-approval trials, sometimes
referred to as "Phase 4" clinical trials, may be conducted after initial marketing approval. These trials are used to gain
additional experience from the treatment of patients in the intended therapeutic indication. In certain instances, FDA may mandate the
performance of such "Phase 4" clinical trials.
Concurrent with clinical trials,
sponsors usually complete additional animal safety studies, develop additional information about the chemistry and physical characteristics
of the product candidate, and finalize a process for manufacturing commercial quantities of the product candidate in accordance with cGMP
requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and the manufacturer
must develop methods for testing the quality, purity, and potency of the product candidate. To help reduce the risk of the introduction
of adventitious agents with use of biological products, the PHSA emphasizes the importance of manufacturing control for products whose
attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing quality batches of the product
candidate and, among other criteria, the sponsor must develop methods for testing the identity, strength, quality, potency, and purity
of the final biological product. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted
to demonstrate that the biological product candidate does not undergo unacceptable deterioration over its shelf life. Additionally, appropriate
packaging must be selected and tested and stability studies must be conducted to demonstrate that the product candidate does not undergo
unacceptable deterioration over its proposed shelf-life.
107
The results of product development,
nonclinical studies, and clinical trials, along with descriptions of the manufacturing process, analytical tests and other control mechanisms,
proposed labeling, and other relevant information are submitted to the FDA as part of a BLA requesting approval to market the product.
Under the Prescription Drug User Fee Act, or PDUFA, as amended, each BLA must be accompanied by a significant user fee. The FDA adjusts
the PDUFA user fees on an annual basis. PDUFA also imposes an annual product fee for products and an annual establishment fee on facilities
used to manufacture prescription biological or drug products. Fee waivers or reductions are available in certain circumstances, such as
where a waiver is necessary to protect the public health, where the fee would present a significant barrier to innovation, or where the
applicant is a small business submitting its first human therapeutic application for review.
Within 60 days following submission
of the application, the FDA reviews a BLA submitted to determine if it is substantially complete before the agency accepts it for filing.
The FDA may refuse to accept for filing any BLA that it deems incomplete or not properly reviewable at the time of submission, and may
request additional information. In this event, the BLA must be resubmitted with the additional information. The resubmitted application
also is subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive
review of the BLA. The FDA reviews the BLA to determine, among other things, whether the proposed product is safe, potent, and/or effective
for its intended use, and has an acceptable purity profile and whether the product is being manufactured in accordance with cGMP. The
FDA may refer applications for novel products or products that present difficult questions of safety or efficacy to an advisory committee,
typically a panel that includes clinicians and other experts, for review, evaluation, and a recommendation as to whether the application
should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such
recommendations carefully when making decisions.
During the product approval
process, the FDA also will determine whether a Risk Evaluation and Mitigation Strategy, or REMS, plan is necessary to assure the safe
use of the product. If the FDA concludes a REMS plan is needed, the sponsor of the BLA must submit a proposed REMS plan. The FDA will
not approve a BLA without a REMS plan, if required. The FDA has authority to require a REMS plan to ensure that the benefits of a drug
or therapeutic biologic outweigh the risks. Before approving a BLA, the FDA will inspect the facilities at which the product is manufactured.
The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP
requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving
a BLA, the FDA will typically inspect one or more clinical sites to assure that the clinical trials were conducted in compliance with
IND trial requirements and GCP requirements. To assure cGMP and GCP compliance, an applicant must incur significant expenditure of time,
money, and effort in the areas of training, record keeping, production, and quality control. Notwithstanding the submission of relevant
data and information, the FDA may ultimately decide that the BLA does not satisfy its regulatory criteria for approval and deny approval.
Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently than we interpret the same data.
If the agency decides not to approve the BLA in its present form, the FDA will issue a complete response letter that describes all of
the specific deficiencies in the BLA identified by the FDA. The deficiencies identified may be minor, for example, requiring labeling
changes, or major, for example, requiring additional clinical trials. Additionally, the complete response letter may include recommended
actions that the applicant might take to place the application in a condition for approval. If a complete response letter is issued, the
applicant may either resubmit the BLA, addressing all of the deficiencies identified in the letter, or withdraw the application. Even
if a product receives regulatory approval, the approval may be significantly limited to specific indications and dosages or the indications
for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain
contraindications, warnings, or precautions be included in the product labeling. The FDA may impose restrictions and conditions on product
distribution, prescribing, or dispensing in the form of a risk management plan, or otherwise limit the scope of any approval.
108
Post-approval requirements
Once an approval is granted,
the FDA may withdraw the approval if compliance with regulatory requirements is not maintained or if problems occur after the product
candidate reaches the market. Later discovery of previously unknown problems with a product candidate may result in restrictions on the
product candidate or even complete withdrawal of the product candidate from the market. After approval, some types of changes to the approved
product candidate, such as adding new indications, manufacturing changes, and additional labeling claims, are subject to further FDA review
and approval. In addition, the FDA may under some circumstances require testing and surveillance programs to monitor the effect of approved
therapeutic candidates that have been commercialized, and the FDA under some circumstances has the power to prevent or limit further marketing
of a product candidate based on the results of these post-marketing programs.
Any therapeutic candidates
manufactured or distributed by us pursuant to FDA approvals are subject to continuing regulation by the FDA, including, among other things:
●
record-keeping requirements;
●
reporting of adverse experiences with the product candidate;
●
providing the FDA with updated safety and efficacy information;
●
product sampling and distribution requirements;
●
notifying the FDA and gaining its approval of specified manufacturing or labeling changes; and
●
complying with FDA promotion and advertising requirements, which include, among other things, standards for direct-to-consumer advertising, restrictions on promoting products for uses or in patient populations that are not described in the product's approved labeling, limitations on industry-sponsored scientific and educational activities and requirements for promotional activities involving the internet.
Therapeutic manufacturers
and other entities involved in the manufacture and distribution of approved therapeutic products are required to register their establishments
with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and some state agencies for compliance
with cGMPs and other laws. The FDA periodically inspects manufacturing facilities to assess compliance with cGMP, which imposes extensive
procedural, substantive, and record-keeping requirements. In addition, changes to the manufacturing process are strictly regulated, and,
depending on the significance of the change, may require FDA approval before being implemented. FDA regulations would also require investigation
and correction of any deviations from cGMP and impose reporting and documentation requirements upon us and any third-party manufacturers
that we may decide to use if our product candidates are approved. Accordingly, manufacturers must continue to expend time, money, and
effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance.
The Orphan Drug Act
Under the Orphan Drug Act,
the FDA may grant Orphan Drug Designation to drugs intended to treat a rare disease or condition — generally a disease or condition
that affects fewer than 200,000 individuals in the United States. Orphan Drug Designation must be requested before submitting a BLA.
After the FDA grants Orphan Drug Designation, the generic identity of the drug and its potential orphan use are disclosed publicly by
the FDA. Orphan Drug Designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.
The first BLA applicant to receive FDA approval for a particular active ingredient to treat a particular disease with FDA Orphan Drug
Designation is entitled to a seven-year exclusive marketing period in the United States for that product, for that indication. During
the seven-year exclusivity period, the FDA may not approve any other applications to market the same drug for the same disease, except
in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity. Orphan drug exclusivity
does not prevent the FDA from approving a different drug for the same disease or condition, or the same drug for a different disease or
condition. Among the other benefits of Orphan Drug Designation are tax credits for certain research and a waiver of the BLA application
user fee.
109
New legislation and regulations
From time to time, legislation
is drafted, introduced, and passed in Congress that could significantly change the statutory provisions governing the testing, approval,
manufacturing, and marketing of products regulated by the FDA. In addition to new legislation, FDA regulations, guidance documents, and
policies are often revised or interpreted by the agency in ways that may significantly affect our business and our products. It is impossible
to predict whether further new legislation will be enacted or FDA regulations, guidance documents, policies, or interpretations changed
or what the effect of such changes, if any, may be.
Review and approval of drug products outside the United States
In order to market any drug
product outside of the United States, a company must also comply with numerous and varying regulatory requirements of other countries
and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorization,
commercial sales, and distribution of drug products. Whether or not it obtains FDA approval for a product, the company would need to obtain
the necessary approvals by the comparable foreign regulatory authorities before it can commence clinical trials or marketing of the product
in those countries or jurisdictions. The approval process ultimately varies between countries and jurisdictions and can involve additional
product testing and additional administrative review periods. The time required to obtain approval in other countries and jurisdictions
might differ from and be longer than that required to obtain FDA approval. Regulatory approval in one country or jurisdiction does not
ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country or jurisdiction may negatively
impact the regulatory process in others.
Pharmaceutical coverage, pricing and reimbursement
In the United States and markets
in other countries, patients who are prescribed treatments for their conditions and providers performing the prescribed services generally
rely on third-party payors to reimburse all or part of the associated healthcare costs. Significant uncertainty exists as to the coverage
and reimbursement status of products approved by the FDA and other government authorities. Thus, even if a product candidate is approved,
sales of the product will depend, in part, on the extent to which third-party payors, including government health programs in the United
States such as Medicare and Medicaid, commercial health insurers and managed care organizations, provide coverage, and establish adequate
reimbursement levels for, the product. The process for determining whether a payor will provide coverage for a product may be separate
from the process for setting the price or reimbursement rate that the payor will pay for the product once coverage is approved. Third-party
payors are increasingly challenging the prices charged, examining the medical necessity, and reviewing the cost-effectiveness of medical
products and services and imposing controls to manage costs. Third-party payors may limit coverage to specific products on an approved
list, also known as a formulary, which might not include all of the approved products for a particular indication.
In order to secure coverage
and reimbursement for any product that might be approved for sale, a company may need to conduct expensive pharmacoeconomic studies in
order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the costs required to obtain FDA or other
comparable marketing approvals. Nonetheless, product candidates may not be considered medically necessary or cost effective. A decision
by a third-party payor not to cover a product candidate could reduce physician utilization once the product is approved and have a material
adverse effect on sales, results of operations and financial condition. Additionally, a payor's decision to provide coverage for
a product does not imply that an adequate reimbursement rate will be approved. Further, one payor's determination to provide coverage
for a drug product does not assure that other payors will also provide coverage and reimbursement for the product, and the level of coverage
and reimbursement can differ significantly from payor to payor.
The containment of healthcare
costs also has become a priority of federal, state and foreign governments and other third-party payors, and the prices of drugs have
been a focus in this effort. Governments have shown significant interest in implementing cost-containment programs, including price controls,
restrictions on reimbursement, and requirements for substitution of generic products. Adoption of price controls and cost-containment
measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit a company's
revenue generated from the sale of any approved products. Coverage policies and third-party reimbursement rates may change at any time.
Even if favorable coverage and reimbursement status is attained for one or more products for which a company or its collaborators receive
marketing approval, less favorable coverage policies and reimbursement rates may be implemented in the future.
110
Outside the United States,
ensuring adequate coverage and payment for a product also involves challenges. Pricing of prescription pharmaceuticals is subject to governmental
control in many countries. Pricing negotiations with governmental authorities can extend well beyond the receipt of regulatory marketing
approval for a product and may require a clinical trial that compares the cost effectiveness of a product to other available therapies.
The conduct of such a clinical trial could be expensive and result in delays in commercialization.
Healthcare law and regulation
Healthcare providers and third-party
payors play a primary role in the recommendation and prescription of drug products that are granted marketing approval. Arrangements with
providers, consultants, third-party payors, and customers are subject to broadly applicable fraud and abuse, anti-kickback, false claims
laws, reporting of payments to physicians and teaching physicians, patient privacy laws and regulations, and other healthcare laws and
regulations that may constrain business and/or financial arrangements. Restrictions under applicable federal and state healthcare laws
and regulations include the following:
●
the federal Anti-Kickback Statute, which prohibits, among other things, a person or entity from knowingly and willfully soliciting, offering, paying, receiving, or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, lease, order, arrange for or recommendation of, any good, facility, item or service, for which payment may be made, in whole or in part, by a federal healthcare program such as Medicare or Medicaid. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. Violation of the federal Anti-Kickback Statue carries criminal penalties and fines as well as administrative sanctions under the Civil Money Penalties Law. In addition, a violation of the Anti-Kickback Statute can form the basis for a violation of the federal False Claims Act;
●
federal civil and criminal false claims laws, including the civil False Claims Act, and civil monetary penalties laws, which prohibit an individual or entity from, among other things, knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false, fictitious, or fraudulent or knowingly making, using, or causing to made or used a false record or statement to avoid, decrease, or conceal an obligation to pay money to the federal government;
●
the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program, or knowingly and willingly falsifying, concealing, or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items, or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;
●
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, and their respective implementing regulations, including the Final Omnibus Rule published in January 2013, which impose obligations on certain covered entity healthcare providers, health plans, and healthcare clearinghouses as well as their business associates that perform certain services involving the use or disclosure of individually identifiable health information, including mandatory contractual terms, with respect to safeguarding the privacy, security, and transmission of individually identifiable health information, and require notification to affected individuals and regulatory authorities of certain breaches of security of individually identifiable health information;
●
the federal false statements statute, which prohibits knowingly and willfully falsifying, concealing, or covering up a material fact, or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items, or services;
111
●
the federal transparency requirements known as the federal Physician Payments Sunshine Act, created by the Patient Protection and Affordable Care Act, as amended by the Health Care Education Reconciliation Act, or the ACA, which requires certain manufacturers of drugs, devices, biologics, and medical supplies for which payment is available under Medicare, Medicaid, or the Children's Health Insurance Program to report annually to the Centers for Medicare & Medicaid Services, or CMS, information related to payments and other transfers of value made to physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members; and
●
analogous local, state, and foreign laws and regulations, such as state anti-kickback and false claims laws that may apply to healthcare items or services that are reimbursed by third-party payors, including private insurers; local, state, and foreign transparency laws that require manufacturers to report information related to payments and transfers of value to other health care providers and health care entities, or marketing expenditures; state laws that require pharmaceutical companies to register certain employees engaged in marketing activities in the locale and comply with the pharmaceutical industry's voluntary compliance guidelines or relevant compliance guidance promulgated by the federal government; and state and foreign laws that govern the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.
If our operations are found
to be in violation of any such requirements, we may be subject to sanctions, including criminal fines, significant civil monetary penalties,
individual imprisonment, disgorgement, contractual damages, reputational harm, exclusion from participation in government healthcare programs,
integrity obligations, injunctions, recall or seizure of products, total or partial suspension of production, denial or withdrawal of pre-marketing product
approvals, private qui tam actions brought by individual whistleblowers in the name of the government, refusal to allow us to enter into
supply contracts, including government contracts, and the curtailment or restructuring of our operations, any of which could adversely
affect our ability to operate our business and our results of operations. Although effective compliance programs can mitigate the risk
of investigation and prosecution for violations of these laws, these risks cannot be entirely eliminated. Any action against us for an
alleged or suspected violation could cause us to incur significant legal expenses and could divert our management's attention from
the operation of our business, even if our defense is successful. In addition, achieving and sustaining compliance with applicable laws
and regulations may be costly to us in terms of money, time and resources.
Healthcare reform
In both the United States
and certain foreign jurisdictions, there have been a number of legislative and regulatory changes to the health care system that could
impact our ability to sell our products profitably. In particular, in 2010, the ACA was enacted, which, among other things, addressed
a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs and biologics;
increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program; extended the Medicaid Drug Rebate
program to utilization of prescriptions of individuals enrolled in Medicaid managed care organizations; subjected manufacturers to new
annual fees and taxes for certain branded prescription drugs; created a new Medicare Part D coverage gap discount program, in which manufacturers
must agree to offer 50% (increased to 70% as of January 1, 2019 and further revised, effective January 1, 2025 under the IRA), point-of-sale discounts
off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer's
outpatient drugs to be covered under Medicare Part D; and provided incentives to programs that increase the federal government's
comparative effectiveness research. Effective January 1, 2025, certain provisions of the Inflation Reduction Act of 2022 will reduce
Medicare Part D beneficiaries' annual out-of-pocket maximum from $7,050 to $2,000, thereby effectively eliminating the
coverage gap.
112
Since its enactment, there
have been numerous judicial, administrative, executive and legislative challenges to certain aspects of the ACA. On June 17, 2021,
the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on
the constitutionality of the ACA. Prior to the Supreme Court's decision, President Biden issued an executive order to initiate a
special enrollment period from February 15, 2021 through August 15, 2021 for purposes of obtaining health insurance coverage
through the ACA marketplace. The executive order also instructed certain governmental agencies to review and reconsider their existing
policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs
that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through
Medicaid or the ACA. It is unclear how other healthcare reform measures of the Biden administration or other efforts, if any, to challenge,
repeal or replace the ACA will impact our business.
Other legislative changes
have been proposed and adopted in the United States since the ACA was enacted:
●
In August 2011, the Budget Control Act of 2011 and subsequent legislation, among other things, created measures for spending reductions by Congress, including a reduction of Medicare payments to providers up to 2% per fiscal year, and, due to subsequent legislative amendments, this will remain in effect through 2030 unless additional Congressional action is taken.
●
The U.S. American Taxpayer Relief Act of 2012 was signed into law in 2013, which among other things, further reduced Medicare payments to several types of providers.
●
On May 30, 2018, the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA permission under the FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result of the Right to Try Act.
●
The Further Consolidated Appropriations Act, signed into law in 2019, repealed the Cadillac tax, the health insurance provider tax, and the medical device excise tax. It is impossible to determine whether similar taxes could be instituted in the future.
There has been increasing
legislative and enforcement interest in the United States with respect to product pricing practices. Specifically, there have been several
recent U.S. Congressional inquiries and proposed federal and state legislation designed to, among other things, bring more transparency
to drug pricing, reduce the cost of therapies under Medicare, review the relationship between pricing and manufacturer patient programs,
and reform government program reimbursement methodologies for drug products. The HHS has already started the process of soliciting feedback
on some of these measures and, at the same time, is immediately implementing others under its existing authority. It is unclear what effect
such legislative and enforcement interest may have on our product candidates.
Further, on December 13,
2016, President Obama signed the 21st Century Cures Act, or Cures Act, into law. Among other provisions, the Cures Act reauthorized the
existing priority review voucher program for certain drugs intended to treat rare pediatric diseases until 2020; created a new priority
review voucher program for drug applications determined to be material national security threat medical countermeasure applications; revised
the FDCA to streamline review of combination product applications; required the FDA to evaluate the potential use of "real world
evidence" to help support approval of new indications for approved drugs; provided a new "limited population" approval
pathway for antibiotic and antifungal drugs intended to treat serious or life-threatening infections; and authorized the FDA to designate
a drug as a "regenerative advanced therapy," thereby making it eligible for certain expedited review and approval designations.
We expect that these and other
healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional downward
pressure on the price that we receive for any approved product, which could have an adverse effect on customers for our product candidates.
Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payers.
There have been, and likely
will continue to be, legislative and regulatory proposals at the foreign, federal and state levels in the U.S. directed at broadening
the availability of healthcare and containing or lowering the cost of healthcare. The implementation of cost containment measures or other
healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our products. Such reforms
could have an adverse effect on anticipated revenue from product candidates that we may successfully develop and for which we may obtain
regulatory approval and may affect our overall financial condition and ability to develop products. If we, or any third parties we may
engage, are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or such
third parties are not able to maintain regulatory compliance, our current or any future product candidates we may develop may lose any
regulatory approval that may have been obtained and we may not achieve or sustain profitability.
113
Employees
As of October 1, 2024,
we have 15 full-time employees and one part-time employee; 12 of whom are primarily engaged in research and development activities and
6 of whom have an M.D. or Ph.D. degree. None of our employees are represented by a labor union or covered by a collective bargaining agreement.
Facilities
We occupy approximately 13,974
square feet of office and laboratory space in Woburn, Massachusetts, under a lease that expires on September 30, 2025, which we use
for our corporate headquarters as well as certain of our research and development activities. We occupy approximately 2,800 square feet
of office and laboratory space in Burlington, Massachusetts, under a lease that expires on April 30, 2025, which we use primarily
for research and development activities.
Legal Proceedings
From time to time, we may
become involved in litigation relating to claims arising from the ordinary course of business. Our management believes that there are
currently no claims or actions pending against us, the ultimate disposition of which would have a material adverse effect on our results
of operations, financial condition or cash flows.
In January 2023, we entered
into a settlement agreement with Parexel International (IRL) Limited relating to payment obligations arising out of a clinical trial performed
by Parexel, which was co-financed by our company and Mabwell (Shanghai) Bioscience Co., Ltd. (SHA: 688062), a biopharmaceutical
company headquartered in Shanghai, China ("Mabwell"). Our company made some but not all installment payments due under the
settlement agreement and Parexel filed a complaint in Superior Court in Middlesex County, Massachusetts in April 2023. Parexel subsequently
amended the complaint twice and filed a motion for default judgment in September 2023 seeking contractual damages of approximately $640,000
plus additional damages under Massachusetts Chapter 93A for deceptive business practices. A hearing on the motion was held on January 9,
2024. The court asked for additional submissions by January 16, 2024 and indicated that a ruling would follow thereafter. On January 26,
2024, the court entered a judgment in the case awarding Parexel a total of approximately $700,000 and rejecting Parexel's claim
under Chapter 93A.
In March 2017, we entered
into an Exclusive License Agreement with Memorial Sloan Kettering Cancer Center ("MSK"), which was subsequently amended by
Amendment No. 1 to Exclusive License Agreement dated March 31, 2017, Amendment No. 2 to Exclusive License Agreement dated
March 31, 2018, and Amendment No. 3 to Exclusive License Agreement dated December 31, 2019 (collectively, the "Exclusive
MSK License Agreement"). In June 2023, we received a notice of breach from MSK followed by a notice of termination in September
2023, pursuant to which MSK demanded payments totaling at least $1,060,404.91 in principal and $169,173.45 in interest. We do not dispute
the payment obligations under the Exclusive MSK License Agreement and have not made the payment to preserve cash. As of October 2024,
we are working to finalize a settlement agreement including a cash component significantly less than the face amount of the obligation.
On August 12, 2024, our landlord filed a Summary Process (Eviction) Summons and Complaint with the District Court in Woburn, Massachusetts
relating to our Cummings Park premises. On November 25, 2024, the Summons was dismissed by the landlord.
We are unable to predict the
ultimate outcome of these matters, the timing of any final decisions of various agencies or courts, or the impact on our results of operations,
financial condition or cash flows.

Non-Employee Directors
Anthony D. Eisenberg
has served as a director of New Abpro since the Business Combination. Prior to the Business Combination, Mr. Eisenberg served
as ACAB's Chief Strategy Officer and served as a director of ACAB since January 2022. Mr. Eisenberg also served as Chief Strategy
Officer and a director of ACA I from February 2021 to October 2023. Since 2013, Mr. Eisenberg has managed Tappan Street, a multi-strategy
family office with expertise in environmental, social and corporate governance principles and private market investments. Since March
2020, Mr. Eisenberg has also served on the board of advisors of Komma, a mobility company targeting the urban mobility vehicle market.
From 2013 to 2019, Mr. Eisenberg served on the board of advisors of Michigan Income Principal-Protected Growth Fund, an impact investing
fund in partnership with the State of Michigan and the US Department of Treasury and led the firm's development activities. Mr.
Eisenberg began his career in politics working in the Office of U.S. Senator Debbie Stabenow, Patton Boggs and the D.C. based research
group Marwood Group, prior to his principal investing career, which began at the hedge fund Christofferson Robb & Company. Mr. Eisenberg
holds an M.B.A. in Finance from Georgetown University-The McDonough School of Business, a J.D. from the University of Michigan Law School
and a B.B.A. in Finance and Political Science from the University of Miami. We believe Mr. Eisenberg's experience in public policy
and expertise in private market investments makes him well-qualified to serve on our Board.
Soo Young Lee

drug division of Celltrion Inc., a leading Korean biopharmaceutical company, since April 2022. From January 2019 to March 2022, Mr. Lee

detection, diagnosis, and treatment, since April 2022. Mr. Lee earned a master's degree from Hanyang University in biochemical engineering,
and he earned a Ph.D. from Inha University in biochemical engineering. We believe that Mr. Lee's experience in drug development,
and his previous service on the board of directors of a pharmaceutical company, qualify him to serve as a member of the board of directors.
Ian McDonald

served as a director of New Abpro since the Business Combination. Mr. McDonald has also served as the Chief Executive Officer and as a
director of Bright Minds Biociences Inc. since 2017. Previously, he served on the management team at a TSX-listed gold mining company,

of dollars in capital. Mr. McDonald has served as a member of the Board of Directors of several TSX Venture Exchange, Canadian Securities
Exchange-listed and private companies. Mr. McDonald has a B.A. in Business from Arizona State University. We believe Mr. McDonald's
experience as an executive and board member of a publicly traded company and in the bioscience industry makes him well-qualified to serve
on our board of directors.
Family Relationships
There are no family relationships
among any of our directors or executive officers.
Board Composition
Our business and affairs are
organized under the direction of our Board. The Board consists of five members upon consummation of the Business Combination. The primary
responsibilities of the Board is to provide oversight, strategic guidance, counseling, and direction to our management. The Board will
meet on a regular basis and additionally as required.
116
In accordance with our Charter,
our Board is divided into three classes, Class I, Class II and Class III, with members of each class serving staggered
three-year terms. The directors are assigned to the following classes:
●
Class I consists of Mr. McDonald, whose term will expire at our 2025 annual meeting of stockholders;
●
Class II consists of Mr. Eisenberg and Mr. Lee, whose terms will expire at our 2026 annual meeting of stockholders; and
●
Class III consists of Mr. Chan and Mr. Suk, whose terms will expire at our 2027 annual meeting of stockholders.
At each annual meeting of
stockholders to be held after the initial classification, the successors to directors whose terms then expire will be elected to serve
from the time of election and qualification until the third annual meeting following their election and until their successors are duly
elected and qualified. This classification of our Board may have the effect of delaying or preventing changes in our control or management.
Director Independence
As a result of our Common
Stock being listed on the Nasdaq, we adhere to the listing rules of the Nasdaq in affirmatively determining whether a director is
independent. Our Board has consulted, and will consult, with its counsel to ensure that the Board's determinations are consistent
with those rules and all relevant securities and other laws and regulations regarding the independence of directors. The Nasdaq listing
standards generally define an "independent director" as a person, other than an executive officer of a company or any other
individual having a relationship which, in the opinion of the issuer's board of directors, would interfere with the exercise of
independent judgment in carrying out the responsibilities of a director.
Each of the directors other
than Mr. Chan and Mr. Suk qualify as independent directors as defined under the listing rules of the Nasdaq, and our board
consists of a majority of independent directors, as defined under the rules of the SEC and Nasdaq Listing Rules relating to
director independence requirements. In addition, we are subject to the rules of the SEC and Nasdaq relating to the membership, qualifications,
and operations of the audit committee, the compensation committee, and the nominating and corporate governance committee, as discussed
below.
Board Oversight of Risk
One of the key functions of
our Board will be informed oversight of its risk management process. The Board does not anticipate having a standing risk management committee,
but rather anticipates administering this oversight function directly through the Board as a whole, as well as through various standing
committees of the Board that address risks inherent in their respective areas of oversight. In particular, our Board will be responsible
for monitoring and assessing strategic risk exposure and our audit committee will have the responsibility to consider and discuss the
combined company's major financial risk exposures and the steps its management will take to monitor and control such exposures,
including guidelines and policies to govern the process by which risk assessment and management is undertaken. The audit committee will
also monitor compliance with legal and regulatory requirements. Our compensation committee will also assess and monitor whether our compensation
plans, policies and programs comply with applicable legal and regulatory requirements. Our nominating and corporate governance committee
will monitor the effectiveness of our governance guidelines and provide oversight with respect to corporate governance.
Committees of the Board
Our Board established an audit
committee, a compensation committee and a nominating and corporate governance committee. Our Board adopted a written charter for each
of these committees, which complies with the applicable requirements of current Nasdaq Listing Rules. Copies of the charters for each
committee are available on the investor relations portion of New Abpro's website. The composition and function of each committee
will comply with all applicable requirements of the Sarbanes-Oxley Act and all applicable SEC rules and regulations.
117
Audit Committee
The members of the audit committee
are Mr. Eisenberg, Mr. McDonald, and Mr. Lee, with Mr. Eisenberg serving as chair. Our Board has determined that each of the members of
the audit committee will be an "independent director" as defined by, and meet the other requirements of the Nasdaq Listing
Rules applicable to members of an audit committee and Rule 10A-3(b)(i) under the Exchange Act, including that each member
of the audit committee can read and understand fundamental financial statements in accordance with Nasdaq audit committee requirements.
In arriving at this determination, the Board examined each audit committee member's scope of experience and the nature of their
prior and current employment. The audit committee will meet on at least a quarterly basis. Both the combined company's independent
registered public accounting firm and management intend to periodically meet privately with our audit committee.
The primary purpose of the
audit committee is to discharge the responsibilities of the Board with respect to our accounting, financial, and other reporting and internal
control practices and to oversee our independent registered accounting firm. Specific responsibilities of our audit committee include:

●
establishing policies for the hiring of employees and former employees of the independent registered public accounting firm.
Audit Committee Financial
Expert
Our Board has determined that
Mr. Eisenberg qualifies as an "audit committee financial expert" as such term is defined in Item 407(d)(5) of Regulation S-K
and meets the financial sophistication requirements of the Nasdaq Listing Rules. In making this determination, our Board considered Mr.
Eisenberg's formal education, training, and previous experience in financial roles.
Compensation Committee
The members of the compensation
committee are Mr. Eisenberg, Mr. McDonald, and Mr. Lee, with Mr. Eisenberg serving as chair. Our Board has determined that each of the
members will be an "independent director" as defined by the Nasdaq Listing Rules applicable to members of a compensation
committee. The Board has determined that each of the members of the compensation committee is a non-employee director, as defined in Rule 16b-3
promulgated under the Exchange Act and satisfy the independence requirements of the Nasdaq. The compensation committee will meet from
time to time to consider matters for which approval by the committee is desirable or is required by law.
Specific responsibilities
of our compensation committee include:
●
reviewing the performance of the Chief Executive Officer and executive management;

assisting the Board in developing and evaluating potential candidates for executive positions (including Chief Executive Officer);
●
reviewing and approving goals and objectives relevant to the Chief Executive Officer and other executive officer compensation, evaluating the Chief Executive Officer's and other executive officers' performance in light of these corporate goals and objectives, and setting Chief Executive Officer and other executive officer compensation levels consistent with its evaluation and New Abpro's philosophy;
●
approving the salaries, bonuses and other compensation for all executive officers;
119
●
reviewing and approving compensation packages for new corporate officers and termination packages for corporate officers as requested by management;
●

Nominating and Corporate
Governance Committee
The members of the nominating
and corporate governance committee are Mr. Eisenberg, Mr. McDonald, and Mr. Lee, with Mr. Eisenberg serving as chair. The Board determined
that each of the members will be an "independent director" as defined by the Nasdaq Listing Rules applicable to members
of a nominating committee. The nominating and corporate governance committee will meet from time to time to consider matters for which
approval by the committee is desirable or is required by law.
120
Specific responsibilities of our nominating and
corporate governance committee include:
●
developing and recommending to the Board the criteria for appointment as a director;
●
identifying, considering, recruiting and recommending candidates to fill new positions on the Board;
●
reviewing candidates recommended by stockholders;
●
conducting the appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates; and
●
recommending director nominees for approval by the Board and election by the stockholders at the next annual meeting.
The nominating and corporate
governance committee will recommend to the board of directors candidates for nomination for election at the annual meeting of the stockholders.
In identifying and evaluating potential candidates, the nominating and corporate governance committee will consider several factors, including,
without limitation, high personal and professional integrity, strong ethics and values, the ability to make mature business judgments,
experience in corporate management such as serving as an officer or former officer of a publicly held company, experience as a board member
of another publicly held company, professional and academic experience relevant to our business, leadership skills, experience in finance
and accounting, or executive compensation practices, whether candidate has the time required for preparation, participation and attendance
at board of directors meetings and committee meetings, if applicable, independence, and the ability to represent the best interests of
New Abpro's stockholders.
Code of Ethics
We have adopted a code of
ethics that applies to all of our directors, officers and employees in accordance with applicable federal securities laws. A copy of our
code of ethics is available on its website. We also intend to post on its website all disclosures that are required by law or the listing
standards of Nasdaq concerning any amendments to, or waivers from, any provision of the code of ethics rather than by filing a Current
Report on Form 8-K.
Clawback Policy
Effective October 2023 ACAB
adopted a Clawback Policy (the "Clawback Policy"). Under the policy, in the event New Abpro is required to prepare an accounting
restatement due to material noncompliance of New Abpro with any financial reporting requirement under the U.S. federal securities laws,
the Board will take, in its discretion, such action it deems necessary to recover from its executive officers who received incentive-based
compensation, based on performance in a year for which New Abpro is required to prepare restated financial statements, the excess of what
would have been paid to the executive officer under the accounting restatement. This applies during a lookback period of three years,
and the amounts to be reclaimed are as determined by the Board in its sole discretion. For purposes of the Clawback Policy, an executive
officer is any of New Abpro's officers who are required, or who have been required during the immediately preceding three calendar
years, to file reports pursuant to Section 16 of the Exchange Act as well as New Abpro's Chief Legal Officer, if not included. This
policy may, in certain circumstances, be applied to other current or former employees whose actions or omissions contributed to the circumstances
requiring the restatement and also involved willful misconduct or a willful violation of any of New Abpro's rules. Additionally,
if the Board determines that detrimental conduct has occurred that results in a material adverse impact, any incentive compensation paid
during the prior year may be subject to clawback. Incentive compensation excludes base salary and other compensation but includes equity
compensation and bonuses.
In October 2022, the SEC adopted
new Rule 10D-1 under the Exchange Act, which requires national securities exchanges, including Nasdaq, to establish listing standards
relating to executive officer incentive compensation clawback and disclosure rules. In February 2023, Nasdaq released its final version
of the proposed listing standards, which require listed companies to adopt, no later than December 1, 2023, clawback policies providing
for the recovery of erroneously awarded incentive-based compensation.
121
Compensation Committee
Interlocks and Insider Participation
None of our executive officers
currently serves, and in the past year has not served, as a member of the compensation committee of any entity that has one or more executive
officers serving on our Board.
Shareholder and Interested
Party Communications
Stockholders and interested
parties may communicate with our Board, any committee chairperson or the non-management directors as a group by writing to the board or
committee chairperson in care of Abpro Holdings, Inc., 68 Cummings Park Drive, Woburn MA 01801. Each communication will be forwarded,
depending on the subject matter, to the Board, the appropriate committee chairperson or all non-management directors.
Limitations of Liability
and Indemnification of Directors and Officers
Our Charter limits a directors'
liability to the fullest extent permitted under the DGCL. The DGCL provides that directors of a corporation will not be personally liable
for monetary damages for breach of their fiduciary duties as directors, except for liability:
●
for any transaction from which the director derives an improper personal benefit;
●
for any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;
●
for any unlawful payment of dividends or redemption of shares; or
●
for any breach of a director's duty of loyalty to the corporation or its stockholders.
If the DGCL is amended to
authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of the directors will
be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.
Delaware law and the Bylaws
provide that New Abpro will, in certain situations, indemnify its directors and officers and may indemnify other employees and other agents,
to the fullest extent permitted by law. Any indemnified person is also entitled, subject to certain limitations, to advancement, direct
payment, or reimbursement of reasonable expenses (including attorneys' fees and disbursements) in advance of the final disposition
of the proceeding.
In addition, New Abpro will
enter into separate indemnification agreements with its directors and officers. These agreements, among other things, require New Abpro
to indemnify its directors and officers for certain expenses, including attorneys' fees, judgments, fines, and settlement amounts
incurred by a director or officer in any action or proceeding arising out of their services as one of its directors or officers or any
other company or enterprise to which the person provides services at its request.
New Abpro plans to maintain
a directors' and officers' insurance policy pursuant to which its directors and officers are insured against liability for
actions taken in their capacities as directors and officers. We believe these provisions in the Charter and the Bylaws and these indemnification
agreements are necessary to attract and retain qualified persons as directors and officers.
Insofar as indemnification
for liabilities arising under the Securities Act may be permitted to directors, officers, or control persons, in the opinion of the SEC,
such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

The compensation of our NEOs
generally consists of base salary, annual cash bonus opportunities, long term incentive compensation in the form of equity awards and
other benefits, as described below.
Base Salary
The base salary payable to
each NEO is intended to provide a fixed component of compensation reflecting the executive's skill set, experience, role, responsibilities,

reviewed (and, if applicable, adjusted) from time to time by Abpro's board of directors.
Bonus
The NEOs are eligible for
a performance-based cash bonus opportunity. Each executive's target bonus is set annually by Abpro's compensation committee.
Long Term Equity Incentives
Abpro's equity-based

Executive Compensation Arrangements
Abpro entered into an employment

to the next Anniversary.
The Chan Employment Agreement
provides for a base salary of $500,000 ("Base Salary"), subject to annual review by Abpro's compensation committee,

is eligible to receive severance consisting of six months of continued base compensation, provided that he sign a separation agreement
and release prepared by Abpro, and provided that he sign a confidentiality, non-compete and non-solicitation agreement,
which contains (i) customary confidentiality provisions, (ii) a non-compete covenant for one year post-termination
of employment, and (iii) non-solicit covenants relating to employees and customers for 24 months and 18 months post-termination
of employment, respectively. The offer letter defines "cause" as (i) poor work performance, as determined by Abpro, (ii)
misconduct, as determined by Abpro, or (iii) any conduct that Abpro deems materially harmful to its business, interests, or reputation.
Christian Zapf
On November 5, 2020, Abpro
provided Christian Zapf with an offer letter setting forth the terms and conditions of his employment as Senior Vice President of Corporate
Development and General Counsel, which provides for a base salary of $325,000, a discretionary bonus with a specified annual target amount
of 35% of his annual base salary, and eligibility to participate in employee benefit programs established by Abpro. Mr. Zapf was granted
180,000 stock options as consideration for entering into Abpro's Employee Non-Solicitation, Non-Competition, Confidentiality and
Assignment Agreement, which contains (i) customary invention assignment and confidentiality provisions and (ii) non-compete and non-solicit
covenants for one year post-termination of employment. Mr. Zapf resigned from his position as Senior Vice President of Corporate Development
and General Counsel of Abpro effective September 23, 2024, prior to the Closing of the Business Combination.

Non- Employee Director Compensation
ACAB
None of ACAB's officers
or directors received any cash compensation for services rendered to ACAB. ACAB provided reimbursement to its non-employee directors
for their reasonable expenses incurred in attending meetings of the ACAB board of directors and its committees. We intend to approve and
implement a compensation program for our non-employee directors.

Abpro
Annual compensation for Abpro's non-employee directors
is composed of cash and stock-based equity compensation. Cash compensation paid to our non-employee directors consists of an
annual retainer.

Summary of the New Abpro Incentive Plan
General
The purpose of the New Abpro
Incentive Plan is to enhance New Abpro's ability to attract, retain and motivate persons who make (or are expected to make) important
contributions by providing these individuals with equity ownership opportunities and/or equity-linked compensatory opportunities. Equity
awards and equity-linked compensatory opportunities are intended to motivate high levels of performance and align the interests of directors,
employees and consultants with those of stockholders by giving directors, employees and consultants the perspective of an owner with an
equity or equity-linked stake in our company and providing a means of recognizing their contributions to New Abpro's success. Our
Board believes that equity ownership opportunities and/or equity-linked compensatory opportunities are necessary to remain competitive
in its industry and are essential to recruiting and retaining the highly qualified employees who help us meet our goals.
Shares of Common Stock Available for Issuance
The New Abpro Incentive Plan
provides for an aggregate of 6,240,773 shares of Common Stock to be reserved for future issuance (the "Initial Share Limit")
plus shares subject to outstanding equity awards granted under Abpro's prior incentive plan that were converted into equity awards
denominated in shares of New Abpro Common Stock under the New Abpro Incentive Plan immediately prior to, the consummation of the Business
Combination, plus an annual increase on the first day of each fiscal year beginning in 2026 and ending in 2034, equal to the lesser of
(A) five (5%) percent of the shares outstanding on the last day of the immediately preceding fiscal year and (B) such smaller number of
shares as determined by the Board or the Committee (as defined below). Shares subject to an award under the New Abpro Incentive Plan that
are forfeited, cancelled, expired, unexercised or are settled in cash under the New Abpro Incentive Plan will again become available for
awards under the New Abpro Incentive Plan. Shares of Common Stock that are tendered or exchanged by a participant or withheld by New Abpro
as payment in connection with any award under the New Abpro Incentive Plan, as well as any shares exchanged by a participant or withheld
by New Abpro or any subsidiary thereof to satisfy tax withholding obligations related to any full value award, will become available for
subsequent awards under the New Abpro Incentive Plan. Shares, if any, that are tendered or exchanged by a participant or withheld by New
Abpro as full or partial payment in connection with the exercise of any option or SAR under the New Abpro Incentive Plan or the payment
of any tax withholding obligation related thereto or not issued by New Abpro in connection with the stock settlement of any SAR will be
added to the aggregate number of shares available for awards under the New Abpro Incentive Plan. Shares, if any, underlying awards that
are granted in assumption of, or in substitution for, outstanding awards previously granted by an entity acquired by New Abpro or with
which New Abpro combines will not be counted against the aggregate number of shares available for awards under the New Abpro Incentive
Plan.
127
Annual Director Limits
A non-employee director of
New Abpro may not be granted awards in respect of such service as a non-employee director under the New Abpro Incentive Plan during any
calendar year that, when aggregated with such non-employee director's cash fees received with respect to such calendar year, exceed
$750,000 in total value; provided, however, that the non-employee directors who are considered independent (under the rules of the Nasdaq
or other securities exchange on which Common Stock is traded) may make exceptions to this limit for a non-executive chair of the Board,
if any, in which case the non-employee director receiving such additional compensation may not participate in the decision to award such
compensation.
Administration
The New Abpro Incentive Plan
will be administered by a committee of at least two people as the Board may appoint, or if no such committee has been appointed by the
Board (the "Committee"). The Committee may interpret the New Abpro Incentive Plan and may prescribe, amend and rescind rules
and make all other determinations necessary or desirable for the administration of the New Abpro Incentive Plan.
The New Abpro Incentive Plan
permits the Committee to select the eligible recipients who will receive awards, to determine the terms and conditions of those awards,
including but not limited to the exercise price or other purchase price of an award, the number of shares of Common Stock or cash or other
property subject to an award, the term of an award and the vesting schedule applicable to an award, and to amend the terms and conditions
of outstanding awards. All decisions made by the Committee pursuant to the provisions of the New Abpro Incentive Plan will be final, conclusive
and binding on all persons.
Eligible Participants
Each of the directors, officers,
employees, consultants, and advisors (or prospective directors, officers, employees, consultants and advisors) of Board or any of its
affiliates are eligible to participate in the New Abpro Incentive Plan, provided that they have been selected by the Committee to receive
awards under the New Abpro Incentive Plan.
Types of Awards
The New Abpro Incentive Plan
provides for the issuance of stock options (including non-statutory stock options and incentive stock options), stock appreciation rights
(referred to as "SARs"), restricted stock, restricted stock units (referred to as "RSUs"), stock bonuses, and
performance compensation awards to directors, officers, employees, consultants, and advisors of New Abpro or its affiliates.
RSUs and Restricted Stock
RSUs and restricted stock
in respect of Common Stock may be granted under the New Abpro Incentive Plan. The Committee will determine the purchase price, vesting
schedule and performance objectives, if any, applicable to the grant of RSUs and restricted stock. If the restrictions, performance objectives
or other conditions determined by the Committee are not satisfied, the RSUs and restricted stock will be forfeited. Subject to the provisions
of the New Abpro Incentive Plan and the applicable individual award agreement, the Committee may provide for the lapse of restrictions
in installments or the acceleration or waiver of restrictions (in whole or part) under certain circumstances as set forth in the applicable
individual award agreement, including the attainment of certain performance goals, a participant's termination of employment or
service under certain circumstances or a participant's death or disability. The rights of holders of RSUs and restricted stock upon
a termination of employment or service will be set forth in individual award agreements.
Unless the applicable award
agreement provides otherwise, participants with restricted stock will generally have all of the rights of a stockholder during the restricted
period, including the right to vote and receive dividends declared with respect to such restricted stock, provided, that any dividends
declared during the restricted period with respect to such restricted stock will only become payable if the underlying restricted stock
vests. During the restricted period, participants with RSUs will generally not have any rights of a stockholder, but, if the applicable
individual award agreement so provides, may be credited with dividend equivalent rights that will be paid at the time that shares in respect
of the related RSUs are delivered to the participant.
128
Options
Options to acquire Common
Stock may be granted under the New Abpro Incentive Plan. Options may be in the form of non-qualified options or "incentive stock
options" within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended, as set forth in the applicable individual
option award agreement. The maximum number of shares that may be granted pursuant to options intended to be incentive stock options under
the New Abpro Incentive Plan is equal to the Initial Share Limit (subject to adjustment in accordance with the terms of the New Abpro
Incentive Plan). The exercise price of all options granted under the New Abpro Incentive Plan will be determined by the Committee, but
in no event may the exercise price be less than 100% of the fair market value of the underlying shares of Common Stock on the date of
grant (other than options granted in substitution or previously granted awards, as defined in the New Abpro Incentive Plan). The maximum
term of all options granted under the New Abpro Incentive Plan will be determined by the Committee, but may not exceed 10 years. Each
option will vest and become exercisable (including in the event of the optionee's termination of employment or service) at such
time and subject to such terms and conditions as determined by the Committee and set forth in the applicable individual option agreement..
Stock Appreciation Rights
SARs may be granted under
the New Abpro Incentive Plan either alone or in conjunction with all or part of any option granted under the New Abpro Incentive Plan.
A SAR granted under the New Abpro Incentive Plan entitles its holder to receive, at the time of exercise, an amount per share equal to
the excess of the fair market value (at the date of exercise) of a share of Common Stock over the base price of the SAR. A SAR granted
in conjunction with all or part of an option under the New Abpro Incentive Plan entitles its holder to receive, at the time of exercise
of the SAR and surrender of the related option, an amount per share equal to the excess of the fair market value (at the date of exercise)
of a share of Common Stock over the exercise price of the related option. Each SAR will be granted with a base price that is not less
than 100% of the fair market value of the related shares of Common Stock on the date of grant (other than SARs granted in substitution
of previously granted awards). The maximum term of all SARs granted under the New Abpro Incentive Plan will be determined by the Committee,
but may not exceed 10 years. The Committee may determine to settle the exercise of a SAR in Common Stock, cash, or any combination thereof.
Each SAR will vest and become
exercisable (including in the event of the SAR holder's termination of employment or service under certain circumstances) at such
time and subject to such terms and conditions as determined by the Committee and set forth in in the applicable individual SAR agreement.
SARs granted in conjunction with all or part of an option will be exercisable at such times and subject to all of the terms and conditions
applicable to the related option.
Stock Bonuses and Cash Awards
The Committee may issue unrestricted
shares of Common Stock or other awards denominated in Common Stock, either alone or in tandem with other awards, in such amounts as the
Committee may determine in its sole discretion from time to time. Each stock bonus award will be evidenced by an award agreement setting
forth the terms and conditions of such awards.
Performance Goals
The Committee may grant equity-based
awards and incentives under the New Abpro Incentive Plan that are subject to the achievement of performance objectives selected by the
Committee in its sole discretion, including, without limitation, one or more of the following business criteria: (i) net earnings or net

on a net or gross basis); (iv) gross profit or gross profit growth; (v) operating profit (before or after taxes); (vi) return measures
(including, but not limited to, return on assets, capital, invested capital, equity, or sales); (vii) cash flow (including, but not limited
to, operating cash flow, free cash flow, net cash provided by operations and cash flow return on capital); (viii) financing and other
capital raising transactions (including, but not limited to, sales of New Abpro's equity or debt securities); (ix) earnings before
or after taxes, interest, depreciation and/or amortization; (x) gross or operating margins; (xi) productivity ratios; (xii) share price
(including, but not limited to, growth measures and total stockholder return); (xiii) expense targets; (xiv) margins; (xv) productivity

(xxix) cost targets; (xxx) reductions and savings; (xxxi) productivity and efficiencies; (xxxii) strategic partnerships or transactions;
and (xxxiii) personal targets, goals or completion of projects.
129
Any one (1) or more of the
performance criteria may be used on an absolute or relative basis to measure the performance of New Abpro and/or one or more affiliates
as a whole or any business unit(s) of New Abpro and/or one or more affiliates or any combination thereof, as the Committee may deem appropriate,
or any of the above performance criteria may be compared to the performance of a selected group of comparison or peer companies, or a
published or special index that the Board, in its sole discretion, deems appropriate, or as compared to various stock market indices.
The Committee also has the authority to provide for accelerated vesting of any award based on the achievement of performance goals pursuant
to the performance criteria. Any performance criteria that are financial metrics, may be determined in accordance with GAAP or may be
adjusted when established to include or exclude any items otherwise includable or excludable under GAAP.
Equitable Adjustments
In the event of (i) any dividend
(other than ordinary cash dividends) or other distribution (whether in the form of cash, Common Stock, other securities or other property),
recapitalization, stock split, reverse stock split, reorganization, merger, amalgamation, consolidation, spin-off, split-up, split-off,
combination, repurchase or exchange of shares of Common Stock or other securities of New Abpro, issuance of warrants or other rights to
acquire Common Stock or other securities of New Abpro, or other similar corporate transaction or event (including, without limitation,
a change in control (as defined below)) that affects Common Stock, or (ii) unusual or infrequently occurring events (including, without
limitation, a change in control) affecting New Abpro, any affiliate, or the financial statements of New Abpro or any affiliate, or changes
in applicable rules, rulings, regulations or other requirements of any governmental body or securities exchange or inter-dealer quotation
system, accounting principles or law, such that in either case an adjustment is determined by the Committee in its sole discretion to
be necessary or appropriate to prevent the dilution or enlargement of the benefits intended to be made available under the New Abpro Incentive
Plan, then the Committee shall make any such adjustments in such manner as it may deem equitable, including without limitation any or
all of the following: (a) adjusting any or all of (A) the number of shares of Common Stock or other securities of New Abpro (or number
and kind of other securities or other property) that may be delivered in respect of awards or with respect to which awards may be granted
under the New Abpro Incentive Plan, and (B) the terms of any outstanding award, including, without limitation, (1) the number of shares
of Common Stock or other securities of New Abpro (or number and kind of other securities or other property) subject to outstanding awards
or to which outstanding awards relate, (2) the exercise price with respect to any award or (3) any applicable performance measures (including,
without limitation, performance criteria and performance goals); (b) providing for a substitution or assumption of awards in a manner
that substantially preserves the applicable terms of such awards; (c) accelerating the exercisability or vesting of, lapse of restrictions
on, or termination of, awards or providing for a period of time for exercise prior to the occurrence of such event; (d) modifying the
terms of awards to add events, conditions or circumstances (including termination of employment within a specified period after a change
in control) upon which the exercisability or vesting of or lapse of restrictions thereon will accelerate; (e) deeming any performance
measures (including, without limitation, performance criteria and performance goals) satisfied at target, maximum or actual performance
through closing or such other level determined by the Committee in its sole discretion, or providing for the performance measures to continue
(as is or as adjusted by the Committee) after closing; (f) providing that for a period prior to the change in control determined by the
Committee in its sole discretion, any options or SARs that would not otherwise become exercisable prior to the change in control will
be exercisable as to all shares of Common Stock subject thereto (but any such exercise will be contingent upon and subject to the occurrence
of the change in control and if the change in control does not take place after giving such notice for any reason whatsoever, the exercise
will be null and void) and that any options or SARs not exercised prior to the consummation of the change in control will terminate and
be of no further force and effect as of the consummation of the change in control; and (g) canceling any one or more outstanding awards
and causing to be paid to the holders thereof, in cash, Common Stock, other securities or other property, or any combination thereof,
the value of such awards.
130
Change in Control
For purposes of the New Abpro
Incentive Plan, a "change in control" means, in summary, the first to occur of any of the following events: (i) one person
or group of persons becomes the beneficial owner, directly or indirectly, of more than 50% of the combined voting power of the then issued
and outstanding securities of New Abpro, whether pursuant to a sale of securities, merger or otherwise, (ii) during any period of not
more than two (2) consecutive years, individuals who constitute the Board as of the beginning of the period cease for any reason to constitute
at least a majority of the Board or (iii) the consummation of a sale, transfer or other disposition of all or substantially all of the
business and assets of New Abpro, whether by sale of assets, merger or otherwise (determined on a consolidated basis), to one person or
group of persons.
Tax Withholding
Each participant will be required
to make arrangements satisfactory to the Committee regarding payment of an amount up to the maximum statutory rates in the participant's
applicable jurisdictions with respect to any award granted under the New Abpro Incentive Plan, as determined by New Abpro. New Abpro has
the right, to the extent permitted by law, to deduct any such taxes from any payment of any kind otherwise due to the participant. With
the approval of the Committee, the participant may satisfy the foregoing requirement by either electing to have New Abpro withhold from
delivery of shares of Common Stock, cash or other property, as applicable, or by delivering already owned unrestricted shares of Common
Stock, in each case, having a value not exceeding the applicable taxes to be withheld and applied to the tax obligations. New Abpro may
also use any other method of obtaining the necessary payment or proceeds, as permitted by law, to satisfy its withholding obligation with
respect to any award.
Amendment and Termination of the Plan
The New Abpro Incentive Plan
provides the Board with authority to amend, alter or terminate the New Abpro Incentive Plan, but no such action may impair the rights
of any participant with respect to outstanding awards without the participant's consent. The Committee may amend an award, prospectively
or retroactively, but no such amendment may materially impair the rights of any participant without the participant's consent. Stockholder
approval of any such action will be obtained if required to comply with applicable law.
Plan Term
The New Abpro Incentive Plan
will terminate on November 7, 2034, although awards
granted before that time will remain outstanding in accordance with their terms.
Following the consummation
of the Business Combination, New Abpro intends to file with the SEC a registration statement on Form S-8 covering the shares of Common
Stock issuable under the New Abpro Incentive Plan.
Material U.S. Federal Income Tax Consequences
The following is a general
summary under current law of the principal United States federal income tax consequences related to awards under the New Abpro Incentive
Plan. This summary deals with the general federal income tax principles that apply and is provided only for general information. Some
kinds of taxes, such as state, local and foreign income taxes, and federal employment taxes, are not discussed. This summary is not intended
as tax advice to participants, who should consult their own tax advisors.
Non-Qualified Stock Options
.
If an optionee is granted an NSO under the New Abpro Incentive Plan, the optionee should not have taxable income on the grant of the option.
Generally, the optionee should recognize ordinary income at the time of exercise in an amount equal to the fair market value of the shares
acquired on the date of exercise, less the exercise price paid for the shares. The optionee's basis in our common stock for purposes
of determining gain or loss on a subsequent sale or disposition of such shares generally will be the fair market value of our common stock
on the date the optionee exercises such option. Any subsequent gain or loss will be taxable as a long-term or short-term capital gain
or loss. We or our subsidiaries or affiliates generally should be entitled to a federal income tax deduction at the time and for the same
amount as the optionee recognizes ordinary income.
131
Incentive Stock Options
.
A participant receiving ISOs should not recognize taxable income upon grant or at the time of exercise. However, the excess of the fair
market value of the shares of our common stock received over the option exercise price is an item of tax preference income potentially
subject to the alternative minimum tax. If stock acquired upon exercise of an ISO is held for a minimum of two years from the date of
grant and one year from the date of exercise and otherwise satisfies the ISO requirements, the gain or loss (in an amount equal to the
difference between the fair market value on the date of disposition and the exercise price) upon disposition of the stock will be treated
as a long-term capital gain or loss, and we will not be entitled to any deduction. If the holding period requirements are not met, the
ISO will be treated as one that does not meet the requirements of the Code for ISOs and the participant will recognize ordinary income
at the time of the disposition equal to the excess of the amount realized over the exercise price, but not more than the excess of the
fair market value of the shares on the date the ISO is exercised over the exercise price, with any remaining gain or loss being treated
as capital gain or capital loss. We and our subsidiaries or affiliates generally are not entitled to a federal income tax deduction upon
either the exercise of an ISO or upon disposition of the shares acquired pursuant to such exercise, except to the extent that the participant
recognizes ordinary income on disposition of the shares.
Other Awards
. The current
federal income tax consequences of other awards authorized under the New Abpro Incentive Plan generally follow certain basic patterns:
SARs are taxed and deductible in substantially the same manner as NSOs; nontransferable restricted stock subject to a substantial risk
of forfeiture results in income recognition equal to the excess of the fair market value over the price paid, if any, only at the time
the restrictions lapse (unless the recipient elects to accelerate recognition as of the date of grant through a Section 83(b) election
under the Code); RSUs, dividend equivalents and other stock or cash based awards are generally subject to tax at the time of (unless the
recipient elects to accelerate recognition as of the date of grant through a Section 83(b) election under the Code); RSUs, dividend equivalents
and other stock or cash based awards are generally subject to tax at the time of payment. We and our subsidiaries or affiliates generally
should be entitled to a federal income tax deduction at the time and for the same amount as the optionee recognizes ordinary income.
Section 409A of the Code
Certain types of awards under
the New Abpro Incentive Plan may constitute, or provide for, a deferral of compensation subject to Section 409A of the Code. Unless certain
requirements set forth in Section 409A of the Code are complied with, holders of such awards may be taxed earlier than would otherwise
be the case (e.g., at the time of vesting instead of the time of payment) and may be subject to an additional 20% penalty tax (and, potentially,
certain interest, penalties and additional state taxes). To the extent applicable, the New Abpro Incentive Plan and awards granted under
the New Abpro Incentive Plan are intended to be structured and interpreted in a manner intended to either comply with or be exempt from
Section 409A of the Code and the Department of Treasury regulations and other interpretive guidance that may be issued under Section 409A
of the Code. To the extent determined necessary or appropriate by the plan administrator, the New Abpro Incentive Plan and applicable
award agreements may be amended to further comply with Section 409A of the Code or to exempt the applicable awards from Section 409A of
the Code.
New Plan Benefits
The benefits or amounts that
may be received or allocated to participants under the New Abpro Incentive Plan will be determined at the discretion of the plan administrator
and are not currently determinable.
Form S-8
When permitted by SEC rules,
we intend to file with the SEC a registration statement on Form S-8 covering the Common Stock of New Abpro issuable
under the New Abpro Incentive Plan.

to rollover RSUs and options of Abpro Corporation and 6,240,773 shares of Common Stock reserved for future issuance under the New Abpro

Founder Shares
In October 2021, the Sponsor
purchased 7,187,500 Founder Shares for an aggregate purchase price of $25,000, or approximately $0.0035 per share. Due to the underwriters'
election to partially exercise their overallotment option, 3,750 shares were forfeited. In October 2021, the Sponsor transferred 50,000
Founder Shares to each of Ms. Lord, Mr. Kahlon, Mr. Stanwood, Mr. Dove and Mr. Schiano, ACAB's independent
directors. The number of Founder Shares issued was determined based on the expectation that such Founder Shares would represent approximately
20% of the outstanding shares upon completion of the ACAB IPO. On January 13, 2022, ACAB effectuated a 1.044-for-1 stock
split, resulting in an aggregate of 7,503,750 founder shares outstanding and held by the Initial Stockholders.
On April 18, 2023, the
Sponsor, ACAB's independent directors, and Apeiron Investment Group Ltd (collectively, the "Series B Holders") voluntarily
converted 7,499,999 shares of Series B common stock of ACAB they held as of such date into 7,499,999 shares of Series A common stock of
the Company (the "Conversion") in accordance with the charter amendment. With respect to shares of Series A common stock that
they received as result of the Conversion, the Series B Holders (i) agreed that they would not vote such stock until after the closing
of a business combination and (ii) acknowledged that such stock would not be entitled to any distribution from ACAB's trust account.
On December 15, 2023, ACAB held a special meeting of stockholders to approve a charter amendment proposal to further extend the date by
which ACAB must consummate a business combination to September 19, 2024 (subject to additional approval by the ACAB Board (as defined
below)). On December 13, 2023, holders of an aggregate of 2,768,301 shares of Series A common stock exercised, and did not reverse, their
right to redeem their shares, and as a result, such holders received a payment of approximately $10.68 per share redeemed. On September
19, 2024, at a special meeting of the stockholders, the stockholders approved a proposal to amend ACAB's Certificate of Incorporation
to extend the date by which ACAB must complete its initial business combination from September 19, 2024 to October 19, 2024 and to allow
ACAB, without another stockholder vote, to elect to extend the October 19, 2024 termination date by resolution of ACAB's board of
directors, if requested by the Sponsor, until November 19, 2024, unless the Closing shall have occurred prior thereto.
On September 19, 2024, holders
of an aggregate of 126,122 shares of Series A common stock exercised, and did not reverse, their right to redeem their shares, and as
a result, such holders received a payment of approximately $11.29 per share redeemed. As a result of the conversion and the results of
the stockholder meetings described above, ACAB has an aggregate of 8,041,268 shares of Series A common stock outstanding and one (1) share

of 13,850,000 Placement Warrants at a price of $1.00 per warrant ($13,850,000 in the aggregate) in a private placement that occurred simultaneously
with the closing of the ACAB IPO. Each Placement Warrant entitled the holder thereof to purchase one share of ACAB's Series A common
stock at a price of $11.50 per share. The Placement Warrants (including the Series A common stock issuable upon exercise thereof) may
not, subject to certain limited exceptions, be transferred, assigned or sold by the holder.
136
Registration Rights
The holders of Founder Shares,
Placement Warrants and any units the Sponsor or our officers, directors or their affiliates may be issued in payment of working capital
loans made to us (and all underlying securities), are entitled to registration rights pursuant to a Registration Rights Agreement dated
January 13, 2022, by and among ACAB, the Sponsor and certain other securityholders of ACAB. The holders of a majority of these securities
are entitled to make up to three demands that we register such securities. The holders of a majority of the units issued in payment of
working capital loans made to us (or underlying securities) can elect to exercise these registration rights at any time after we consummate
a business combination. In addition, the holders have certain "piggy-back" registration rights with respect to registration
statements filed subsequent to our consummation of a business combination. We will bear the expenses incurred in connection with the filing
of any such registration statements.
Director and Officer Reimbursement
No compensation of any kind,
including any finder's fee, reimbursement, consulting fee or monies in respect of any payment of a loan, was paid by ACAB to the
Sponsor, officers and directors, or any of their respective affiliates, prior to, or in connection with any services rendered in order
to effectuate, the consummation of the Business Combination, other than the repayment of any loans from the Sponsor, officers and directors
for working capital purposes and reimbursement of any out-of-pocket expenses incurred in connection with activities on ACAB's
behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. ACAB did not have
a policy that prohibited the Sponsor, executive officers or directors, or any of their respective affiliates, from negotiating for the
reimbursement of out-of-pocket expenses by a target business. ACAB's audit committee reviewed on a quarterly basis all
payments that were made to the Sponsor, officers, directors or ACAB or their respective affiliates and determined which expenses and the
amount of expenses that would be reimbursed. There was no cap or ceiling on the reimbursement of out-of-pocket expenses incurred
by such persons in connection with activities on ACAB's behalf.
Related Party Notes
In October 2021, the Sponsor
agreed to loan ACAB an aggregate of up to $250,000 to cover expenses related to the ACAB IPO pursuant to a promissory note (the "2021
Note"). The 2021 Note was non-interest bearing and payable upon the completion of the ACAB IPO. The outstanding borrowings
under the 2021 Note in the amount of $149,539 were repaid on February 22, 2022.
On October 14, 2023
and November 14, 2023, ACAB issued unsecured promissory notes (the "Extension Promissory Notes") to the Sponsor in the
aggregate principal amounts of $80,000 and $80,000, respectively, in connection with monthly extensions of the deadline to consummate

with the Business Combination.
137
Expense Advance Agreement
On May 30, 2024, ACAB and
the Sponsor entered into an expense advancement agreement (the "Expense Advancement Agreement"), pursuant to which the Sponsor
agreed to advance to ACAB up to $600,000 in the aggregate, including previous amounts advanced from the Sponsor to ACAB, on an interest-free
basis as may be necessary to cover working capital expenses, fund certain redemptions of the ACAB's common stock and cover costs

Series B common stock held by it. At Closing, the Sponsor forfeited 966,442 shares of Common Stock pursuant to the Sponsor Letter Agreement.
Deferred Underwriting Fee
On January 8, 2024, ACAB and Cantor entered into the Fee Reduction
Agreement, pursuant to which Cantor has agreed to settle $10,290,000 of the deferred underwriting fees payable, resulting in a remainder
of $6,000,000 of deferred underwriting fees payable (the "Reduced Deferred Fee") by the Company to Cantor upon the Closing.
The Reduced Deferred Fee was paid at Closing to Cantor in the form of 600,000 shares of Common Stock. The Fee Reduction Agreement only
applied to the consummation of the Business Combination with Abpro.
138
Polar Subscription Agreement
On April 10, 2024, ACAB, Polar
Multi-Strategy Master Fund ("Polar"), and the Sponsor entered into a subscription agreement (the "Polar Subscription
Agreement") pursuant to which Polar agreed to provide a capital contribution to the Sponsor in an aggregate amount of up to $360,000
(the "Capital Contribution") in exchange for 1 share of ACAB's Series A common stock held by the Sponsor for each $1
invested by Polar as of the closing of ACAB's initial business combination, provided that the obligation to make capital contributions
would terminate on November 19, 2024 (the date by which ACAB must consummate its initial business combination). Funds invested by Polar
pursuant to the Polar Subscription Agreement would in turn will be loaned by the Sponsor to ACAB on an interest-free basis (the "SPAC
Loan") in order to fund ACAB's working capital needs and other expenses in connection with the Business Combination. As of
June 30, 2024, Polar funded $345,051 of the Capital Contribution to the Sponsor.
Upon the consummation of the
Business Combination, ACAB paid to the Sponsor the principal amount outstanding under the SPAC Loan. In addition, Polar received from
the Sponsor 360,000 shares of Common Stock, an amount equal to the Capital Contribution, which represented 1 share of Common Stock for
each $10 invested by Polar as of the Closing Date.
Other Material Interests Relating to the Business Combination
ACAB's directors and
officers will be eligible for continued indemnification and continued coverage under ACAB's directors' and officers'
liability insurance for six years after the Closing Date pursuant to the Business Combination Agreement.
Procedures with Respect to Review and Approval of Related Person
Transactions
Our Code of Business Conduct
and Ethics requires us to avoid, wherever possible, all related party transactions that could result in actual or potential conflicts
of interests, except under guidelines approved by the Board (or the audit committee). Related-party transactions are defined as transactions
in which (1) the aggregate amount involved will or may be expected to exceed $120,000 in any calendar year, (2) we or any of
our subsidiaries is a participant, and (3) any (a) executive officer, director or nominee for election as a director, (b) greater
than 5% beneficial owner of our shares of common stock, or (c) immediate family member of the persons referred to in clauses (a) and
(b), has or will have a direct or indirect material interest (other than solely as a result of being a director or a less than 10% beneficial
owner of another entity). A conflict of interest situation can arise when a person takes actions or has interests that may make it difficult
to perform his or her work objectively and effectively. Conflicts of interest may also arise if a person, or a member of his or her family,
receives improper personal benefits as a result of his or her position.
Our audit committee, pursuant
to its written charter, is responsible for reviewing and approving related-party transactions to the extent we enter into such transactions.
The audit committee will consider all relevant factors when determining whether to approve a related party transaction, including whether
the related party transaction is on terms no less favorable to us than terms generally available from an unaffiliated third-party under
the same or similar circumstances and the extent of the related party's interest in the transaction. No director may participate
in the approval of any transaction in which he is a related party, but that director is required to provide the audit committee with all
material information concerning the transaction. We also require each of our directors and executive officers to complete a directors'
and officers' questionnaire that elicits information about related party transactions.
These procedures are intended
to determine whether any such related party transaction impairs the independence of a director or presents a conflict of interest on the
part of a director, employee or officer.
To further minimize conflicts
of interest, we have agreed not to consummate an initial business combination with an entity that is affiliated with any of the Sponsor
or our officers or directors including (i) an entity that is either a portfolio company of, or has otherwise received a material
financial investment from, any private equity fund or investment company (or an affiliate thereof) that is affiliated with any of the
foregoing, (ii) an entity in which any of the foregoing or their affiliates are currently passive investors, (iii) an entity
in which any of the foregoing or their affiliates are currently officers or directors, or (iv) an entity in which any of the foregoing
or their affiliates are currently invested through an investment vehicle controlled by them, unless we have obtained an opinion from an
independent investment banking firm, or another independent entity that commonly renders valuation opinions on the type of target business
we are seeking to acquire, and the approval of a majority of our disinterested independent directors that the business combination is
fair to our unaffiliated stockholders from a financial point of view. Furthermore, no finder's fees, reimbursements, consulting
fee, monies in respect of any payment of a loan or other compensation will be paid by us to the Sponsor, our officers or directors, or
any of their respective affiliates, for services rendered to us prior to, or in connection with any services rendered in order to effectuate,
the consummation of our initial business combination (regardless of the type of transaction that it is), other than the repayment of any
loans from the Sponsor, officers and directors for working capital purposes and reimbursement of any out-of-pocket expenses
incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable
business combinations.
139
DESCRIPTION OF CAPITAL
STOCK
The following summary is not
intended to be a complete summary of the rights and preferences of such securities, and is qualified by reference to the Charter and Bylaws,
copies of which are filed as exhibits to the registration statement of which this prospectus forms a part. We urge you to read the Charter
and Bylaws in their entirety for a complete description of the rights and preferences of our securities following the consummation of
the Business Combination.
Authorized Capitalization
New Abpro's authorized
capital stock consists of 110,000,000 shares of common stock, par value $0.0001 per share, and 1,000,000 shares of preferred stock, par
value $0.0001 per share. As of the date of this prospectus, there are 51,815,765 shares of Common Stock issued and outstanding. No shares
of preferred stock are issued and outstanding. Unless the Board determines otherwise, New Abpro will issue all shares of its capital stock
in uncertificated form.
Common Stock
Voting rights.
Holders
of shares of Common Stock are entitled to one (1) vote for each share of common stock held as of the record date on all matters submitted
to a vote of stockholders, provided, however, that, except as otherwise required in the Charter or by applicable law, the holders of Common
Stock will not be entitled to vote on any amendment to our Charter that relates solely to the terms of one or more outstanding series
of preferred stock if the holders of such affected series are entitled, either separately or together with the holders of one or more
other such series, to vote thereon pursuant to our Charter (including any certificate of designation relating to any series of preferred
stock) or pursuant to the DGCL.
Dividend rights.
Subject
to applicable law and the rights and preferences of the holders of any outstanding series of New Abpro preferred stock, and to the other
provisions of the Charter, the holders of Common Stock shall be entitled to the payment of dividends on the common stock in cash, in property
or in shares of New Abpro when, as and if declared thereon by the Board from time to time out of assets or funds of New Abpro legally
available therefor.
Rights upon liquidation.
Subject
to the rights of holders of preferred stock, upon New Abpro's liquidation, dissolution or winding up and after payment in full of
all amounts required to be paid to creditors and to any future holders of preferred stock having liquidation preferences, if any, the
holders of Common Stock will be entitled to receive pro rata New Abpro's remaining assets available for distribution.
Post-Combination Company Preferred Stock
Under the terms of the Charter,
the Board is authorized to direct us to issue shares of preferred stock in one or more series without stockholder approval. The Board
has the discretion to determine the rights, powers, preferences, privileges and restrictions, including voting rights, dividend rights,
conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock.
140
The purpose of authorizing
the Board to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote
on specific issuances. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions, future financings
and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third
party from seeking to acquire, a majority of the outstanding voting stock. Additionally, the issuance of preferred stock may adversely
affect the holders of common stock by restricting dividends on the common stock, diluting the voting power of the common stock or subordinating
the liquidation rights of the common stock. As a result of these or other factors, the issuance of preferred stock could have an adverse
impact on the market price of the Common Stock.
Warrants
Public Warrants
There is currently outstanding
an aggregate of 15,000,000 Public Warrants, which entitle the holder to acquire Common Stock. Each whole warrant will entitle the registered
holder to purchase one share of Common Stock at an exercise price of $11.50 per share. A holder may exercise its warrants only for a whole
number of shares of Common Stock. This means only a whole warrant may be exercised at a given time by a warrant holder. The warrants will
expire at 5:00 p.m., New York City time, on the earlier to occur of five (5) years after the completion of the Business Combination or
redemption.
New Abpro will not be obligated
to deliver any shares of Common Stock pursuant to the exercise of a Public Warrant and will have no obligation to settle such warrant
exercise unless a registration statement under the Securities Act covering the issuance of the shares of Common Stock issuable upon exercise
of the Public Warrants is then effective and a current prospectus relating thereto is available, subject to New Abpro satisfying its obligations
described below with respect to registration, or a valid exemption from registration is available, including in connection with a cashless
exercise. No Public Warrant will be exercisable for cash or on a cashless basis, and New Abpro will not be obligated to issue any shares
to holders seeking to exercise their warrants, unless the issuance of the shares upon such exercise is registered or qualified under the
securities laws of the state of the exercising holder, or an exemption from registration is available. In the event that the conditions
in the two immediately preceding sentences are not satisfied with respect to a Public Warrant, the holder of such warrant will not be
entitled to exercise such warrant and such warrant may have no value and expire worthless.
As soon as practicable, but
in no event later than twenty (20) business days after the Closing, New Abpro will use its commercially reasonable efforts to file with
the SEC a registration statement covering the issuance, under the Securities Act, of the shares of Common Stock issuable upon exercise
of the Public Warrants, and will use commercially reasonable efforts to cause the same to become effective within sixty (60) business
days after the Closing and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until
the expiration of the Public Warrants in accordance with the provisions of the Warrant Agreement. Notwithstanding the above, if shares
of Common Stock are, at the time of any exercise of a Public Warrant, not listed on a national securities exchange such that they satisfy
the definition of a "covered security" under Section 18(b)(1) of the Securities Act, New Abpro may, at its option, require
holders of Public Warrants who exercise their warrants to do so on a "cashless basis" in accordance with Section 3(a)(9)
of the Securities Act and, in the event New Abpro so elects, it will not be required to file or maintain in effect a registration statement,
but will use its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption
is not available. In such event, each holder would pay the exercise price by surrendering the Public Warrants for that number of shares
of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the
Public Warrants, multiplied by the excess of the "fair market value" (defined below) less the exercise price of the Public
Warrants by (y) the fair market value. The "fair market value" means the volume weighted average price of the shares
of Common Stock for the 10 trading days ending on the trading day prior to the date on which the notice of exercise is received by the
warrant agent.
141
Redemption of Public Warrants
Once the warrants become exercisable,
New Abpro may redeem the outstanding warrants (except as described herein with respect to the Placement Warrants):
●
in whole and not in part;
●
at a price of $0.01 per warrant;
●
upon not less than 30 days' prior written notice of redemption (the "30-day redemption period") to each warrant holder; and
●
if, and only if, the last reported sale price of the Common Stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending three business days before New Abpro sends the notice of redemption to the warrant holders.
New Abpro will not redeem
the Public Warrants as described above unless a registration statement under the Securities Act covering the issuance of the shares of
Common Stock issuable upon exercise of the Public Warrants is then effective and a current prospectus relating to those shares of Common
Stock is available throughout the 30-day redemption period. If and when the Public Warrants become redeemable, New Abpro may
exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state
securities laws.
The redemption criterion discussed
above was established to prevent a redemption call unless there is at the time of the call a significant premium to the Public Warrant
exercise price. If the foregoing conditions are satisfied and New Abpro issues a notice of redemption of the Public Warrants, each warrant
holder will be entitled to exercise his, her or its warrant prior to the scheduled redemption date. However, the price of shares of New
Abpro common stock may fall below the $18.00 redemption trigger price (as adjusted for stock splits, stock capitalizations, reorganizations,
recapitalizations and the like) as well as the $11.50 Public Warrant exercise price after the redemption notice is issued.
If New Abpro calls the Public
Warrants for redemption as described above, its management will have the option to require any holder that wishes to exercise its Public
Warrant to do so on a "cashless basis." In determining whether to require all holders to exercise their warrants on a "cashless
basis," New Abpro's management will consider, among other factors, New Abpro's cash position, the number of warrants
that are outstanding and the dilutive effect on New Abpro's stockholders of issuing the maximum number of shares of P Common Stock
issuable upon the exercise of its Public Warrants. If New Abpro's management takes advantage of this option, all holders of Public
Warrants would pay the exercise price by surrendering their warrants for that number of shares of Common Stock equal to the quotient obtained
by dividing (x) the product of the number of shares of Common Stock underlying the Public Warrants, multiplied by the excess of the
"fair market value" of Common Stock over the exercise price of the Public Warrants by (y) the fair market value. The
"fair market value" will mean the average last reported sale price of shares of Common Stock for the ten trading days ending
on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. If New Abpro's
management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of
shares of Common Stock to be received upon exercise of the Public Warrants, including the "fair market value" in such case.
Requiring a cashless exercise in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a
warrant redemption. If New Abpro calls the Public Warrants for redemption and management does not take advantage of this option, the Sponsor
and its permitted transferees would still be entitled to exercise their Placement Warrants for cash or on a cashless basis using the same
formula described above that other warrant holders would have been required to use had all warrant holders been required to exercise their
warrants on a cashless basis, as described in more detail below.
A holder of a warrant may
notify New Abpro in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise
such warrant, to the extent that after giving effect to such exercise, such person (together with such person's affiliates), to
the warrant agent's actual knowledge, would beneficially own in excess of 9.8% (or such other amount as a holder may specify) of
Common Stock outstanding immediately after giving effect to such exercise.
142
Anti-Dilution Adjustments
If the number of outstanding
shares of Common Stock is increased by a share capitalization payable in shares of Common Stock, or by a split-up of common
stock or other similar event, then, on the effective date of such share capitalization, split-up or similar event, the number
of shares of Common Stock issuable on exercise of each warrant will be increased in proportion to such increase in the outstanding shares
of common stock. A rights offering to holders of common stock entitling holders to purchase Common Stock at a price less than the fair
market value will be deemed a share capitalization of a number of shares of Common Stock equal to the product of  (i) the
number of shares of Common Stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights
offering that are convertible into or exercisable for Common Stock) and (ii) the quotient of  (x) the price per share
of Common Stock paid in such rights offering and (y) the fair market value. For these purposes (i) if the rights offering is
for securities convertible into or exercisable for shares of Common Stock, in determining the price payable for Common Stock, there will
be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion
and (ii) fair market value means the VWAP of shares of Common Stock as reported during the ten (10) trading day period ending
on the trading day prior to the first date on which New Abpro common stock trades on the applicable exchange or in the applicable market,
regular way, without the right to receive such rights.
In addition, if New Abpro,
at any time while the warrants are outstanding and unexpired, pays a dividend or makes a distribution in cash, securities or other assets
to the holders of Common Stock on account of such Common Stock (or other securities into which the warrants are convertible), other than
(a) as described above, or (b) certain ordinary cash dividends.
If the number of outstanding
shares of Common Stock is decreased by a consolidation, combination, reverse share split or reclassification of Common Stock or other
similar event, then, on the effective date of such consolidation, combination, reverse share split, reclassification or similar event,
the number of shares of Common Stock issuable on exercise of each warrant will be decreased in proportion to such decrease in outstanding
share of Common Stock.
Whenever the number of shares
of Common Stock purchasable upon the exercise of the warrants is adjusted, as described above, the warrant exercise price will be adjusted
by multiplying the warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the
number of shares of Common Stock purchasable upon the exercise of the warrants immediately prior to such adjustment, and (y) the
denominator of which will be the number of shares of Common Stock so purchasable immediately thereafter.
In the case of any reclassification
or reorganization of the outstanding Common Stock (other than those described above or that solely affects the par value of such Common
Stock), or in the case of any merger or consolidation of New Abpro with or into another corporation (other than a consolidation or merger
in which New Abpro is the continuing corporation and that does not result in any reclassification or reorganization of the outstanding
Common Stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of New Abpro
as an entirety or substantially as an entirety in connection with which New Abpro is dissolved, the holders of the warrants will thereafter
have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the warrants and in lieu of Common
Stock immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares
of Common Stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation,
or upon a dissolution following any such sale or transfer, that the holder of the warrants would have received if such holder had exercised
their warrants immediately prior to such event. If less than 70% of the consideration receivable by the holders of Common Stock in such
a transaction is payable in the form of Common Stock in the successor entity that is listed for trading on a national securities exchange
or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such
event, and if the registered holder of the warrant properly exercises the warrant within thirty days following public disclosure of such
transaction, the warrant exercise price will be reduced as specified in the warrant agreement based on the Black-Scholes value (as defined
in the warrant agreement) of the warrant. The purpose of such exercise price reduction is to provide additional value to holders of the
warrants when an extraordinary transaction occurs during the exercise period of the warrants pursuant to which the holders of the warrants
otherwise do not receive the full potential value of the warrants in order to determine and realize the option value component of the
warrant. This formula is to compensate the warrant holder for the loss of the option value portion of the warrant due to the requirement
that the warrant holder exercise the warrant within 30 days of the event. The Black-Scholes model is an accepted pricing model for
estimating fair market value where no quoted market price for an instrument is available.
143
The warrants will be issued
in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and New Abpro.
The warrant agreement provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or
correct any defective provision, and that all other modifications or amendments will require the vote or written consent of the holders
of at least 50% of the then outstanding Public Warrants, and, solely with respect to any amendment to the terms of the Placement Warrants,
a majority of the then outstanding Placement Warrants. You should review a copy of the warrant agreement, which is filed as an exhibit
to the registration statement pertaining to our initial public offering, for a complete description of the terms and conditions applicable
to the warrants.
The warrant holders do not
have the rights or privileges of holders of common stock and any voting rights until they exercise their warrants and receive Common Stock.
After the issuance of Common Stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record
on all matters to be voted on by stockholders.
No fractional shares will
be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest
in a share, New Abpro will, upon exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to
the warrant holder.
Private Placement Warrants
There are currently 13,850,000
Placement Warrants outstanding. The Placement Warrants (including the shares of Common Stock issuable upon exercise of the Placement Warrants)
will not be transferable, assignable or salable until thirty (30) days after the Closing (except in limited circumstances) and they will
not be redeemable by New Abpro so long as they are held by the Sponsor or its permitted transferees. The founders, or their permitted
transferees, have the option to exercise the Placement Warrants for cash or on a cashless basis. Otherwise, the Placement Warrants have
terms and provisions that are identical to the Public Warrants. If the Placement Warrants are held by holders other than the Sponsor or
its permitted transferees, the Placement Warrants will be redeemable by New Abpro in all redemption scenarios and exercisable by the holders
on the same basis as the Public Warrants.
If holders of the Placement
Warrants elect to exercise them on a cashless basis, they would pay the exercise price by surrendering his, her or its warrants for that
number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock
underlying the Placement Warrants, multiplied by the excess of the "fair market value" (defined below) less the exercise price
of the Placement Warrants by (y) the fair market value. For these purposes, the "fair market value" shall mean the average
last reported sale price of the shares of Common Stock for the ten (10) trading days ending on the third trading day prior to the date
on which the notice of warrant exercise is sent to the warrant agent. Even during such periods of time when insiders will be permitted
to sell Post-Combination Company securities, an insider cannot trade in Post-Combination Company securities if he or she is in possession
of material non-public information. Accordingly, unlike public stockholders who could exercise their Public Warrants and sell
the shares of Common Stock received upon such exercise freely in the open market in order to recoup the cost of such exercise, the insiders
could be significantly restricted from selling such securities.
Anti-Takeover Provisions of the Charter and the Bylaws
The Charter and the Bylaws
contain provisions that may delay, defer or discourage another party from acquiring control of us. We expect that these provisions, which
are summarized below, will discourage coercive takeover practices or inadequate takeover bids. These provisions are also designed to encourage
persons seeking to acquire control of us to first negotiate with the Board, which may result in an improvement of the terms of any such
acquisition in favor of the stockholders. However, they also give the Board the power to discourage acquisitions that some stockholders
may favor.
Authorized but Unissued Shares
The authorized but unissued
shares of Common Stock and preferred stock are available for future issuance without stockholder approval, subject to any limitations
imposed by the listing standards of Nasdaq. These additional shares may be used for a variety of corporate finance transactions, acquisitions
and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could make more difficult
or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.
Classified Board of Directors
The Charter provides that
the Board will be divided into three classes of directors, with the classes to be as nearly equal in number as possible, and with each
director serving a three-year term. As a result, approximately one-half of the Board will be elected each year. The classification
of directors will have the effect of making it more difficult for stockholders to change the composition of the Board.
144
Stockholder Action; Special Meetings of Stockholders
The Charter will provide that
stockholders may not take action by written consent, but may only take action at annual or special meetings of stockholders. As a result,
a holder controlling a majority of New Abpro capital stock would not be able to amend New Abpro's bylaws or remove directors without
holding a meeting of stockholders called in accordance with New Abpro's bylaws. Further, the Bylaws will provide that only the chairperson
of the Board, a majority of the Board or the Chief Executive Officer of New Abpro may call special meetings of stockholders, thus prohibiting
a stockholder from calling a special meeting. These provisions might delay the ability of stockholders to force consideration of a proposal
or for stockholders controlling a majority of New Abpro capital stock to take any action, including the removal of directors.
Advance Notice Requirements for Stockholder Proposals and Director
Nominations
In addition, the Bylaws will
establish an advance notice procedure for stockholder proposals to be brought before an annual meeting or special meeting of stockholders.
Generally, in order for any matter to be "properly brought" before a meeting, the matter must be (a) specified in a notice
of meeting given by or at the direction of the Board, (b) if not specified in a notice of meeting, otherwise brought before the meeting
by the Board or the chairperson of the meeting, or (c) otherwise properly brought before the meeting by a stockholder present in
person who (1) was a stockholder at the time of giving the notice, (2) is entitled to vote at the meeting, and (3) has
complied with the advance notice procedures specified in New Abpro's bylaws or properly made such proposal in accordance with Rule 14a-8 under
the Exchange Act and the rules and regulations thereunder, which proposal has been included in the proxy statement for the annual meeting.
Further, for business to be properly brought before an annual meeting by a stockholder, the stockholder must (a) provide Timely Notice
(as defined below) thereof in writing and in proper form to the secretary and (b) provide any updates or supplements to such notice
at the times and in the forms required by the Bylaws. To be timely, a stockholder's notice must be delivered to, or mailed and received
at, New Abpro's principal executive offices not less than ninety (90) days nor more than one hundred twenty (120) days prior
to the one-year anniversary of the preceding year's annual meeting;
provided, however
, that if the date of
the annual meeting is more than thirty (30) days before or more than sixty (60) days after such anniversary date, notice by the stockholder
to be timely must be so delivered, or mailed and received, not later than the 90th day prior to such annual meeting or, if later, the
10th day following the day on which public disclosure of the date of such annual meeting was first made (such notice within such time
periods, "Timely Notice").
Stockholders at an annual
meeting or special meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting
by or at the direction of the Board or by a qualified stockholder of record on the record date for the meeting, who is entitled to vote
at the meeting and who has delivered timely written notice in proper form to New Abpro's secretary of the stockholder's intention
to bring such business before the meeting. These provisions could have the effect of delaying stockholder actions that are favored by
the holders of a majority of the outstanding voting securities until the next stockholder meeting.
No Cumulative Voting
Under the DGCL, there is no
right to vote cumulatively (which allows stockholders to cast all of the votes such stockholder is entitled to for a single nominee for
a board of directors rather than only being able to vote the number of shares such stockholder holds for or against each nominee) unless
expressly authorized in the certificate of incorporation. The Charter does not authorize cumulative voting.
Amendment of Charter or Bylaws
Our Bylaws may be amended
or repealed by a majority vote of the Board or by the holders of at least 66 2/3% of the voting power of all of the then-outstanding shares
entitled to vote generally in the election of directors, voting together as a single class. The affirmative vote of a majority of the
Board and at least 66 2/3% in voting power of the outstanding shares entitled to vote thereon would be required to amend certain provisions
of the Charter.
Limitations on Liability and Indemnification of Officers and Directors
The Charter and Bylaws provide
indemnification and advancement of expenses for New Abpro's directors and officers to the fullest extent permitted by the DGCL,
subject to certain limited exceptions. New Abpro has entered into indemnification agreements with each of its directors and officers.
In some cases, the provisions of those indemnification agreements may be broader than the specific indemnification provisions contained
under Delaware law. In addition, as permitted by Delaware law, the Charter and Bylaws include provisions that eliminate the personal liability
of directors for monetary damages resulting from breaches of certain fiduciary duties as a director. The effect of this provision is to
restrict New Abpro's rights and the rights of New Abpro's stockholders in derivative suits to recover monetary damages against
a director for breach of fiduciary duties as a director.
These provisions may be held
not to be enforceable for violations of the federal securities laws of the United States.
145
Dissenters' Rights of Appraisal and Payment
Under the DGCL, with certain
exceptions, New Abpro's stockholders will have appraisal rights in connection with a merger or consolidation of New Abpro. Pursuant
to Section 262 of the DGCL, stockholders who properly demand and perfect appraisal rights in connection with such merger or consolidation
will have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery.
Stockholders' Derivative Actions
Under the DGCL, any of New
Abpro's stockholders may bring an action in the company's name to procure a judgment in its favor, also known as a derivative
action, provided that the stockholder bringing the action is a holder of New Abpro's shares at the time of the transaction to which
the action relates.
Forum Selection
The Charter and Bylaws provide
that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for the following types of actions or proceedings
under Delaware statutory or common law: (i) any derivative action or proceeding brought on behalf of New Abpro; (ii) any action
or proceeding asserting a claim of breach of a fiduciary duty owed by any of New Abpro's current or former directors, officers,
or other employees to New Abpro or its stockholders; (iii) any action or proceeding asserting a claim against New Abpro or any of
its current or former directors, officers, or other employees, arising out of or pursuant to any provision of the Delaware General Corporation
Law, the Charter or the Bylaws; (iv) any action or proceeding to interpret, apply, enforce, or determine the validity of the Charter
or the Bylaws; (v) any action or proceeding as to which the DGCL confers jurisdiction to the Court of Chancery of the State of Delaware;
and (vi) any action asserting a claim against New Abpro or any of its directors, officers, or other employees governed by the internal
affairs doctrine, in all cases to the fullest extent permitted by law and subject to the court's having personal jurisdiction over
the indispensable parties named as defendants. These provisions would not apply to suits brought to enforce a duty or liability created
by the Exchange Act. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over
all such Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. To prevent having
to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations,
the Charter and Bylaws will further provide that the federal district courts of the United States of America will be the exclusive forum
for resolving any complaint asserting a cause or causes of action arising under the Securities Act, including all causes of action asserted
against any defendant to such complaint. For the avoidance of doubt, this provision is intended to benefit and may be enforced by New
Abpro, its officers and directors, the underwriters to any offering giving rise to such complaint, and any other professional entity whose
profession gives authority to a statement made by that person or entity and who has prepared or certified any part of the documents underlying
this offering. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless
seek to bring a claim in a venue other than those designated in the exclusive forum provisions. In such instance, New Abpro would expect
to vigorously assert the validity and enforceability of the exclusive forum provisions of the Charter and the Bylaws.
These exclusive forum provisions
may limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with New Abpro or its
directors, officers, or other employees and may discourage these types of lawsuits. Furthermore, the enforceability of similar choice
of forum provisions in other companies' certificates of incorporation or bylaws has been challenged in legal proceedings, and it
is possible that a court could find these types of provisions to be inapplicable or unenforceable. We note that investors cannot waive
compliance with the federal securities laws and the rules and regulations thereunder.
Transfer Agent and Registrar
The transfer agent and registrar
for our Common Stock is Continental Stock Transfer & Trust Company.
Trading Symbol and Market
Our Common Stock and our Public
Warrants are listed on the Nasdaq Global Market under the symbols "ABP" and "ABPWW," respectively.

PLAN OF DISTRIBUTION
Each Selling Securityholder
of the securities and any of their pledgees, assignees and successors-in- interest may, from time to time, sell any or all of their securities
covered hereby on the principal trading market for such securities or any other stock exchange, market or trading facility on which the
securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Securityholder may use any
one or more of the following methods when selling securities:
●
ordinary brokerage transactions and transactions in which the broker-dealer solicits Subscribers;
●
block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;
●
purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
●
an exchange distribution in accordance with the rules of the applicable exchange;
●
privately negotiated transactions;
●
settlement of short sales;
●
in transactions through broker-dealers that agree with the Selling Securityholders to sell a specified number of such securities at a stipulated price per security;
●
through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;
●
a combination of any such methods of sale; or
●
any other method permitted pursuant to applicable law.
The Selling Securityholders
may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than
under this prospectus.
Broker-dealers engaged by
the Selling Securityholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts
from the Selling Securityholders (or, if any broker-dealer acts as agent for the Subscriber of securities, from the Subscriber) in amounts
to be negotiated, but except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a
customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown
in compliance with FINRA IM-2440.
150
In connection with the sale
of the securities or interests therein, the Selling Securityholders may enter into hedging transactions with broker-dealers or other financial
institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling
Securityholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the
securities to broker-dealers that in turn may sell these securities. The Selling Securityholders may also enter into option or other transactions
with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer
or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution
may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).
The Selling Securityholders
and any broker-dealers or agents that are involved in selling the securities may be deemed to be "underwriters" within the
meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents
and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities
Act. Each Selling Securityholder has informed the Company that it does not have any written or oral agreement or understanding, directly
or indirectly, with any person to distribute the securities.
The Company is required to
pay certain fees and expenses incurred incident to the registration of the securities. The Company has agreed to indemnify the Selling
Securityholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.
We agreed to keep this prospectus
effective until the earlier of (i) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities
Act or any other rule of similar effect, (ii) they may be sold pursuant to Rule 144 without volume or manner-of-sale restrictions;
or (iii) it has been two years from the Closing Date. The resale securities will be sold only through registered or licensed brokers
or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may
not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification
requirement is available and is complied with.
Under applicable rules and
regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market
making activities with respect to the Common Stock for the applicable restricted period, as defined in Regulation M, prior to the commencement
of the distribution. In addition, the Selling Securityholders will be subject to applicable provisions of the Exchange Act and the rules and
regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the Common Stock by the Selling Securityholders
or any other person. We will make copies of this prospectus available to the Selling Securityholders and have informed them of the need
to deliver a copy of this prospectus to each Subscriber at or prior to the time of the sale (including by compliance with Rule 172
under the Securities Act).
151
UNITED STATES FEDERAL
INCOME TAX CONSIDERATIONS
The following discussion is
a summary of certain material U.S. federal income tax considerations generally applicable to the ownership and disposition of our Common
Stock and Warrants, which we refer to collectively as our securities. This summary is based upon U.S. federal income tax law as of the
date of this prospectus, which is subject to change or differing interpretations, possibly with retroactive effect. This summary does
not discuss all aspects of U.S. federal income taxation that may be important to particular investors in light of their individual circumstances,
including investors subject to special tax rules (
e.g.
, financial institutions, insurance companies, broker-dealers, dealers or
traders in securities, tax-exempt organizations, taxpayers that have elected mark-to-market accounting, S corporations, regulated investment
companies, real estate investment trusts, passive foreign investment companies, controlled foreign corporations, U.S. Holders (as defined
below) that will hold Common Stock or Warrants as part of a straddle, hedge, conversion, or other integrated transaction for U.S. federal
income tax purposes, expatriates or former long-term residents of the United States, or investors that have a functional currency other
than the U.S. dollar), all of whom may be subject to tax rules that differ materially from those summarized below. This summary does not
discuss other U.S. federal tax consequences (
e.g.
, estate or gift tax), any state, local, or non-U.S. tax considerations, or the
Medicare tax or alternative minimum tax. In addition, this summary is limited to investors that will hold our securities as "capital
assets" (generally, property held for investment) under the Internal Revenue Code of 1986, as amended
(the "Code") and that acquire our Common Stock and Warrants for cash pursuant to this prospectus. No ruling from the Internal
Revenue Service, (the "IRS") has been or will be sought regarding any matter discussed herein. No assurance can be given that
the IRS would not assert, or that a court would not sustain a position contrary to, any of the tax aspects set forth below.
For purposes of this summary,
a "U.S. Holder" is a beneficial holder of securities who or that, for U.S. federal income tax purposes is:
●
an individual who is a United States citizen or resident of the United States;
●
a corporation (or other entity taxable as a corporation) created in, or organized under the law of, the United States or any state or political subdivision thereof;
●
an estate the income of which is includible in gross income for United States federal income tax purposes regardless of its source; or
●
a trust (A) the administration of which is subject to the primary supervision of a United States court and which has one or more United States persons (within the meaning of the Code) who have the authority to control all substantial decisions of the trust or (B) that has in effect a valid election under applicable Treasury regulations to be treated as a United States person.
A "Non-U.S. Holder"
is a beneficial holder of securities who or that is neither a U.S. Holder nor a partnership for U.S. federal income tax purposes.
If a partnership (including
an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our securities, the tax treatment of a partner,
member, or other beneficial owner in such partnership will generally depend upon the status of the partner, member, or other beneficial
owner, the activities of the partnership, and certain determinations made at the partner, member, or other beneficial owner level. If
you are a partner, member, or other beneficial owner of a partnership holding our securities, you are urged to consult your tax advisor
regarding the tax consequences of the ownership and disposition of our securities.
THIS DISCUSSION OF U.S. FEDERAL
INCOME TAX CONSIDERATIONS IS FOR GENERAL INFORMATION PURPOSES ONLY AND IS NOT TAX ADVICE. PROSPECTIVE HOLDERS SHOULD CONSULT THEIR TAX
ADVISORS CONCERNING THE U.S. FEDERAL INCOME TAX CONSEQUENCES TO THEM OF OWNING AND DISPOSING OF OUR SECURITIES, AS WELL AS THE APPLICATION
OF ANY, STATE, LOCAL AND NON-U.S. INCOME, ESTATE, AND OTHER TAX CONSIDERATIONS.
U.S. Holders
Taxation of Distributions
If we pay distributions or
make constructive distributions (other than certain distributions of our stock or rights to acquire our stock) to U.S. Holders of shares
of our Common Stock, such distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from
our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of our
current and accumulated earnings and profits will constitute a return of capital that will be applied against and reduce (but not below
zero) the U.S. Holder's adjusted tax basis in our Common Stock. Any remaining excess will be treated as gain realized on the sale
or other disposition of the Common Stock and will be treated as described under "
U.S. Holders — Gain or Loss
on Sale, Taxable Exchange or Other Taxable Disposition of Common Stock
" below.
Dividends we pay to a U.S.
Holder that is a taxable corporation will generally qualify for the dividends received deduction if the requisite holding period is satisfied.
With certain exceptions (including dividends treated as investment income for purposes of investment interest deduction limitations),
and provided certain holding period requirements are met, dividends we pay to a non-corporate U.S. Holder will generally constitute "qualified
dividends" that will be subject to tax at the preferential tax rate accorded to long-term capital gains. If the holding period requirements
are not satisfied, a corporation may not be able to qualify for the dividends received deduction and would have taxable income equal to
the entire dividend amount, and non-corporate holders may be subject to tax on such dividend at ordinary income tax rates instead of the
preferential rates that apply to qualified dividend income.
152
Gain or Loss on Sale, Taxable Exchange
or Other Taxable Disposition of Common Stock
A U.S. Holder generally will
recognize gain or loss on the sale, taxable exchange or other taxable disposition of our Common Stock. Any such gain or loss will be capital
gain or loss and will be long-term capital gain or loss if the U.S. Holder's holding period for the Common Stock so disposed of
exceeds one year. The amount of gain or loss recognized will generally be equal to the difference between (1) the sum of the amount of
cash and the fair market value of any property received in such disposition and (2) the U.S. Holder's adjusted tax basis in its
Common Stock disposed. A U.S. Holder's adjusted tax basis in its Common Stock will generally equal the U.S. Holder's acquisition
cost for such Common Stock (or, in the case of Common Stock received upon exercise of a Warrant, the U.S. Holder's initial basis
for such Common Stock, as discussed below), less any prior distributions treated as a return of capital. The deductibility of capital
losses is subject to limitations. Long-term capital gains recognized by non-corporate U.S. Holders are generally eligible for reduced
rates of tax. If the U.S. Holder's holding period for the Common Stock so disposed of is one year or less, any gain on a sale or
other taxable disposition of the shares would be subject to short-term capital gain treatment and would be taxed at ordinary income tax
rates. The deductibility of capital losses is subject to limitations.
Exercise of a Warrant
Except as discussed below
with respect to the cashless exercise of a Warrant, a U.S. Holder generally will not recognize taxable gain or loss upon the exercise
of a Warrant for cash. The U.S. Holder's initial tax basis in the share of our Common Stock received upon exercise of the Warrant
will generally be an amount equal to the sum of the U.S. Holder's acquisition cost of the Warrant and the exercise price of such
Warrant. It is unclear whether a U.S. Holder's holding period for the Common Stock received upon exercise of the Warrant would commence
on the date of exercise of the Warrant or the day following the date of exercise of the Warrant; however, in either case the holding period
will not include the period during which the U.S. Holder held the Warrants.
The tax consequences of a
cashless exercise of a Warrant are not clear under current tax law. A cashless exercise may be nontaxable, either because the exercise
is not a realization event or because the exercise is treated as a recapitalization for U.S. federal income tax purposes. In either situation,
a U.S. Holder's initial tax basis in the Common Stock received generally should equal the holder's adjusted tax basis in the
Warrant. If the cashless exercise were treated as not being a realization event, it is unclear whether a U.S. Holder's holding period
for the Common Stock would commence on the date of exercise of the Warrant or the day following the date of exercise of the Warrant; in
either case, the holding period would not include the period during which the U.S. Holder held the Warrant. If, instead, the cashless
exercise were treated as a recapitalization, the holding period of the Common Stock generally would include the holding period of the
Warrant.
It is also possible that a
cashless exercise of a Warrant could be treated in part as a taxable exchange in which gain or loss is recognized. In such event, a U.S.
Holder could be deemed to have surrendered a portion of the Warrants being exercised having a value equal to the exercise price of such
Warrants in satisfaction of such exercise price. Although not free from doubt, such U.S. Holder generally should recognize capital gain
or loss in an amount equal to the difference between the fair market value of the Warrants deemed surrendered to satisfy the exercise
price and the U.S. Holder's adjusted tax basis in such Warrants. In this case, a U.S. Holder's initial tax basis in the Common
Stock received would equal the sum of the exercise price and the U.S. holder's adjusted tax basis in the Warrants exercised. It
is unclear whether a U.S. Holder's holding period for the Common Stock would commence on the date of exercise of the Warrant or
the day following the date of exercise of the Warrant; in either case, the holding period would not include the period during which the
U.S. Holder held the Warrant. Due to the uncertainty and absence of authority on the U.S. federal income tax treatment of a cashless exercise,
including when a U.S. Holder's holding period would commence with respect to the Common Stock received, U.S. Holders are urged to
consult their tax advisors regarding the tax consequences of a cashless exercise.
Sale, Exchange, Redemption or Expiration
of a Warrant
Upon a sale, exchange (other
than by exercise), redemption (other than a redemption for Common Stock), or expiration of a Warrant, a U.S. Holder will recognize taxable
gain or loss in an amount equal to the difference between (1) the amount realized upon such disposition or expiration and (2) the U.S.
Holder's adjusted tax basis in the Warrant. A U.S. Holder's adjusted tax basis in its Warrants will generally equal the U.S.
Holder's acquisition cost, increased by the amount of any constructive distributions included in income by such U.S. Holder (as
described below under "
U.S. Holders — Possible Constructive Distributions
"). Such gain or loss
generally will be treated as long-term capital gain or loss if the Warrant is held by the U.S. Holder for more than one year at the time
of such disposition or expiration. If a Warrant is allowed to lapse unexercised, a U.S. Holder will generally recognize a capital loss
equal to such holder's adjusted tax basis in the Warrant. The deductibility of capital losses is subject to certain limitations.
153
A redemption of Warrants for
Common Stock described in this prospectus under "
Description of Securities — Warrants
" should be
treated as a "recapitalization" for U.S. federal income tax purposes. Accordingly, you should not recognize any gain or loss
on the redemption of Warrants for shares of our Common Stock. Your aggregate initial tax basis in the Common Stock received in the redemption
should equal your aggregate adjusted tax basis in your Warrants redeemed and your holding period for the Common Stock received in redemption
of your Warrants should include your holding period for your surrendered Warrants. However, there is some uncertainty regarding this tax
treatment and, accordingly, U.S. Holders should consult their tax advisors regarding the tax consequences of a redemption of Warrants
for Common Stock.
Possible Constructive Distributions
The terms of each Warrant
provide for an adjustment to the number of Common Stock for which the Warrant may be exercised or to the exercise price of the Warrant
in certain events, as discussed in the section of this prospectus captioned "
Description of Securities — Warrants
."
An adjustment which has the effect of preventing dilution generally should not be a taxable event. Nevertheless, a U.S. Holder of Warrants
would be treated as receiving a constructive distribution from us if, for example, the adjustment increases the holder's proportionate
interest in our assets or earnings and profits (e.g., through an increase in the number of shares of Common Stock that would be obtained
upon exercise) as a result of a distribution of cash to the holders of shares of our Common Stock which is taxable to such holders as
a distribution. Such constructive distribution would be subject to tax as described above under "
U.S. Holders — Taxation
of Distributions
" in the same manner as if such U.S. Holder received a cash distribution from us on Common Stock equal to the
fair market value of such increased interest.
Information Reporting and Backup Withholding
In general, information reporting
requirements may apply to dividends paid to a U.S. Holder and to the proceeds of the sale or other disposition of our Common Stock and
Warrants, unless the U.S. Holder is an exempt recipient. Backup withholding may apply to such payments if the U.S. Holder fails to provide
a taxpayer identification number, a certification of exempt status or has been notified by the IRS that it is subject to backup withholding
(and such notification has not been withdrawn).
Backup withholding is not
an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a credit against a U.S. Holder's U.S.
federal income tax liability and may entitle such holder to a refund, provided the required information is timely furnished to the IRS.
Non-U.S. Holders
Taxation of Distributions
In general, any distributions
(including constructive distributions) we make to a Non-U.S. Holder of shares of our Common Stock, to the extent paid out of our current
or accumulated earnings and profits (as determined under U.S. federal income tax principles), will constitute dividends for U.S. federal
income tax purposes and, provided such dividends are not effectively connected with the Non-U.S. Holder's conduct of a trade or
business within the United States, we will be required to withhold tax from the gross amount of the dividend at a rate of 30%, unless
such Non-U.S. Holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification
of its eligibility for such reduced rate (usually on an IRS Form W-8BEN or W-8BEN-E, as applicable). In the case of any constructive dividend
(as described below under "
Non-U.S. Holders — Possible Constructive Distributions
"), it is possible
that this tax would be withheld from any amount owed to a Non-U.S. Holder by the applicable withholding agent, including cash distributions
on other property or sale proceeds from Warrants or other property subsequently paid or credited to such holder. Any distribution not
constituting a dividend will be treated first as reducing (but not below zero) the Non-U.S. Holder's adjusted tax basis in its Common
Stock and, to the extent such distribution exceeds the Non-U.S. Holder's adjusted tax basis, as gain realized from the sale or other
disposition of the Common Stock, which will be treated as described under "
Non-U.S. Holders — Gain on Sale, Taxable Exchange
or Other Taxable Disposition of Common Stock and Warrants
" below. In addition, if we determine that we are likely to be classified
as a "United States real property holding corporation" (see "
Non-U.S. Holders — Gain on Sale,
Exchange or Other Taxable Disposition of Common Stock and Warrants
" below), we will withhold 15% of any distribution that exceeds
our current and accumulated earnings and profits.
Dividends we pay to a Non-U.S.
Holder that are effectively connected with such Non-U.S. Holder's conduct of a trade or business within the United States (or if
a tax treaty applies are attributable to a U.S. permanent establishment or fixed base maintained by the Non-U.S. Holder) will generally
not be subject to U.S. withholding tax, provided such Non-U.S. Holder complies with certain certification and disclosure requirements
(generally by providing an IRS Form W-8ECI). Instead, such dividends generally will be subject to U.S. federal income tax, net of certain
deductions, at the same graduated individual or corporate rates applicable to U.S. Holders. If the Non-U.S. Holder is a corporation, dividends
that are effectively connected income may also be subject to a "branch profits tax" at a rate of 30% (or such lower rate as
may be specified by an applicable income tax treaty).
154
Exercise of a Warrant
The U.S. federal income tax
treatment of a Non-U.S. Holder's exercise of a Warrant will generally correspond to the U.S. federal income tax treatment of the
exercise of a Warrant by a U.S. Holder, as described under "
U.S. Holders — Exercise of a Warrant
"
above, although to the extent a cashless exercise results in a taxable exchange, the tax consequences to the Non-U.S. Holder would be
the same as those described below in "
Non-U.S. Holders — Gain on Sale, Exchange or Other Taxable Disposition
of Common Stock and Warrants
."
Redemption of Warrants for Common Stock
A redemption of Warrants for
Common Stock described in this prospectus under "
Description of Securities — Warrants
" should be
treated as a "recapitalization" for U.S. federal income tax purposes. Accordingly, you should not recognize any gain or loss
on the redemption of Warrants for shares of our Common Stock. Your aggregate initial tax basis in the Common Stock received in the redemption
should equal your aggregate adjusted tax basis in your Warrants redeemed and your holding period for the Common Stock received in redemption
of your Warrants should include your holding period for your surrendered Warrants. However, there is some uncertainty regarding this tax
treatment and, accordingly, Non-U.S. Holders should consult their tax advisors regarding the tax consequences of a redemption of Warrants
for Common Stock.
Gain on Sale, Exchange or Other Taxable
Disposition of Common Stock and Warrants
A Non-U.S. Holder generally
will not be subject to U.S. federal income or withholding tax in respect of gain recognized on a sale, taxable exchange or other taxable
disposition of our Common Stock or Warrants or an expiration or redemption of our Warrants, unless:
●
the gain is effectively connected with the conduct of a trade or business by the Non-U.S. Holder within the United States (and, if an applicable tax treaty so requires, is attributable to a U.S. permanent establishment or fixed base maintained by the Non-U.S. Holder);
●
the Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of disposition and certain other conditions are met; or
●
we are or have been a "United States real property holding corporation" for U.S. federal income tax purposes at any time during the shorter of the five-year period ending on the date of disposition or the period that the Non-U.S. Holder held our Common Stock or Warrants and, in the case where shares of our Common Stock are regularly traded on an established securities market, the Non-U.S. Holder has owned, directly or constructively, more than 5% of our common stock at any time within the shorter of the five-year period preceding the disposition or such Non-U.S. Holder's holding period for the shares of our common stock. There can be no assurance that our Common Stock will be treated as regularly traded on an established securities market for this purpose.
Gain described in the first
bullet point above will be subject to tax at generally applicable U.S. federal income tax rates as if the Non-U.S. Holder were a U.S.
resident. Any gains described in the first bullet point above of a Non-U.S. Holder that is a foreign corporation may also be subject to
an additional "branch profits tax" at a 30% rate (or lower applicable treaty rate). Gain described in the second bullet point
above will generally be subject to a flat 30% U.S. federal income tax. Non-U.S. Holders are urged to consult their tax advisors regarding
possible eligibility for benefits under income tax treaties.
If the third bullet point
above applies to a Non-U.S. Holder and applicable exceptions are not available, gain recognized by such holder on the sale, exchange or
other disposition of our Common Stock or Warrants will be subject to tax at generally applicable U.S. federal income tax rates. In addition,
a buyer of our Common Stock or Warrants from such holder may be required to withhold U.S. income tax at a rate of 15% of the amount realized
upon such disposition. Non-U.S. Holders are urged to consult their tax advisors regarding the application of these rules.
155
Possible Constructive Distributions
The terms of each Warrant
provide for an adjustment to the number of Common Stock for which the Warrant may be exercised or to the exercise price of the Warrant
in certain events, as discussed in the section of this prospectus captioned "
Description of Securities — Warrants
."
An adjustment which has the effect of preventing dilution generally should not be a taxable event. Nevertheless, a Non-U.S. Holder of
Warrants would be treated as receiving a constructive distribution from us if, for example, the adjustment increases the holder's
proportionate interest in our assets or earnings and profits (e.g., through an increase in the number of Common Stock that would be obtained
upon exercise) as a result of a distribution of cash to the holders of our Common Stock which is taxable to such holders as a distribution.
A Non-U.S. Holder would be subject to U.S. federal income tax withholding as described above under "
Non-U.S. Holders — Taxation
of Distributions
" under that section in the same manner as if such Non-U.S. Holder received a cash distribution from us on Common
Stock equal to the fair market value of such increased interest.
Foreign Account Tax Compliance Act
Provisions of the Code and
Treasury Regulations and administrative guidance promulgated thereunder commonly referred as the "Foreign Account Tax Compliance
Act" ("FATCA") generally impose withholding at a rate of 30% in certain circumstances
on dividends (including constructive dividends) in respect of our securities which are held by or through certain foreign financial institutions
(including investment funds), unless any such institution (1) enters into, and complies with, an agreement with the IRS to report, on
an annual basis, information with respect to interests in, and accounts maintained by, the institution that are owned by certain U.S.
persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments, or (2)
if required under an intergovernmental agreement between the United States and an applicable foreign country, reports such information
to its local tax authority, which will exchange such information with the U.S. authorities. An intergovernmental agreement between the
United States and an applicable foreign country may modify these requirements. Accordingly, the entity through which our securities are
held will affect the determination of whether such withholding is required. Similarly, dividends in respect of our securities held by
an investor that is a non-financial non-U.S. entity that does not qualify under certain exceptions will generally be subject to withholding
at a rate of 30%, unless such entity either (1) certifies to us or the applicable withholding agent that such entity does not have any
"substantial United States owners" or (2) provides certain information regarding the entity's "substantial United
States owners," which will in turn be provided to the U.S. Department of Treasury. Withholding under FATCA was scheduled to apply
to payments of gross proceeds from the sale or other disposition of property that produces U.S.-source interest or dividends, however,
the IRS released proposed regulations that, if finalized in their proposed form, would eliminate the obligation to withhold on such gross
proceeds. Although these proposed Treasury Regulations are not final, taxpayers generally may rely on them until final Treasury Regulations
are issued. Prospective investors should consult their tax advisors regarding the possible implications of FATCA on their investment in
our securities.
Information Reporting and Backup Withholding
Information returns will be
filed with the IRS in connection with payments of dividends and the proceeds from a sale or other disposition of our shares of Common
Stock and Warrants. A Non-U.S. Holder may have to comply with certification procedures to establish that it is not a United States person
in order to avoid information reporting and backup withholding requirements. The certification procedures required to claim a reduced
rate of withholding under a treaty generally will satisfy the certification requirements necessary to avoid the backup withholding as
well. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed
as a credit against such holder's U.S. federal income tax liability and may entitle such holder to a refund, provided that the required
information is timely furnished to the IRS.

Atlantic Coastal Acquisition Corp. II. as of December 31, 2023 and 2022 and for the years ended December 31, 2022 and 2023 have been audited
by Marcum LLP, independent registered public accounting firm, as set forth in their report thereon appearing elsewhere in this proxy statement/prospectus,
and are included in reliance on such report given on the authority of such firm as an expert in accounting and auditing.
The consolidated financial
statements of Abpro Corporation as of December 31, 2023 and 2022, and for each of the two years in the period ended December 31, 2023,
included in the Proxy Statement of Atlantic Coastal Acquisition Corp. II, which is referred to and made part of this proxy statement/prospectus
and Registration Statement, have been audited by Wolf & Company, P.C., independent registered public accounting firm, as set forth
in their report appearing elsewhere herein, and are included in reliance upon such report given on the authority of such firm as experts
in accounting and auditing.
LEGAL MATTERS
The validity of the securities
offered by this prospectus has been passed upon for us by Nelson Mullins Riley & Scarborough LLP, Washington, DC.
CHANGE IN REGISTRANT'S CERTIFYING ACCOUNTANT
Effective December 9, 2024,
the Company dismissed Marcum LLP ("Marcum") as its independent registered public accounting firm. On December 9, 2024, the
Company engaged Wolf & Company, P.C. ("Wolf") as Marcum's replacement. The decision to change independent registered
public accounting firms was made with the recommendation and approval of the Audit Committee of the Company.
Marcum's audit reports
on the Company's consolidated financial statements as of and for the fiscal years ended December 31, 2023 and December 31, 2022
did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to audit scope or accounting principles,
except that such reports expressed substantial doubt regarding the Company's ability to continue as a going concern.
During the fiscal years ended
December 31, 2023 and 2022, and the subsequent interim period through the date of this prospectus, there were no disagreements, as that
term is defined in Item 304(a)(1)(iv) of Regulation S-K, between the Company and Marcum on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to Marcum's satisfaction, would
have caused Marcum to make reference to such disagreements in its audit reports.
During the fiscal years ended
December 31, 2023 and 2022, and the subsequent interim period through the date of this prospectus, there were no reportable events within
the meaning of Item 304(a)(1)(v) of Regulation S-K, except for the following material weaknesses which the Company identified in its internal
control over financial reporting: failure to timely file tax returns, utilizing cash withdrawn from the trust account for tax obligations
for operating purposes, and over-accrual of expenses.
During the fiscal years ended
December 31, 2023 and 2022, and the subsequent interim period through the date of this prospectus, neither the Company nor anyone acting
on our behalf of the Company consulted Wolf with respect to either (i) the application of accounting principles to a specified transaction,
either completed or proposed; or the type of audit opinion that might be rendered on the Company's consolidated financial statements,
and no written report or oral advice was provided to the Company by Wolf that Wolf concluded was an important factor considered by the
Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject
of a disagreement, as that term is described in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation
S-K, or a reportable event, as that term is defined in Item 304(a) (1)(v) of Regulation S-K.
The Company delivered a copy
of this disclosure to Marcum and requested that they furnish the Company a letter addressed to the SEC stating whether they agree with
the above statements. In their letter to the SEC dated December 9, 2024, attached as Exhibit 16.1 to the registration statement of which
this prospectus forms a part, Marcum states that they agree with the statements above concerning their firm.

SEPTEMBER

(UNAUDITED)
NOTE
1 — ORGANIZATION AND PLAN OF BUSINESS OPERATIONS
Atlantic Coastal Acquisition Corp. II ("ACAB", now known
as Abpro Holdings, Inc., "Abpro") (the "Company") is a blank check company incorporated in Delaware on May 20,
2021. The Company was formed for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization
or other similar business combination with one or more businesses (a "Business Combination"). The Company is an early stage
and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.
Business
Combination
On November 12, 2024, ACAB and Abpro completed a series
of transactions that resulted in the combination (the "Closing" of the "Business Combination") of ACAB with Abpro
Corporation, a Delaware corporation ("Abpro Corporation"), pursuant to the previously announced Business Combination Agreement,
dated December 11, 2023, amended by an amendment dated September 4, 2024 (the "BCA"), by and among ACAB, Abpro Merger Sub
Corp., a Delaware corporation and a wholly owned subsidiary of ACAB ("Merger Sub"), and Abpro Corporation, following the approval
at the special meeting of the shareholders of ACAB held on November 7, 2024 (the "Special Meeting"). On November 12, 2024,
pursuant to the BCA, and as described in greater detail in the Company's final prospectus and definitive proxy statement, which
was filed with the U.S. Securities and Exchange Commission (the "SEC") on October 18, 2024 (the "Proxy Statement/Prospectus"),
Merger Sub merged with and into Abpro Corporation, with Abpro Corporation surviving the merger as a wholly owned subsidiary of ACAB, and
ACAB changed its name to Abpro Holdings, Inc. ("New Abpro"). As consideration for the Business Combination, New Abpro issued
to or reserved for Abpro Corporation shareholders an aggregate of approximately
50,000,000
shares of New Abpro common stock, par value
$
0.0001
per share (the "Common Stock"), consisting of
39,413,500
shares of Common Stock issued to Abpro Corporation shareholders,
and
10,586,500
shares of Common Stock reserved for issuance in connection with certain Abpro Corporation rollover RSUs and stock options
(collectively, the "Merger Consideration"). In addition, New Abpro issued an aggregate of
3,367,401
shares of Common Stock
to the PIPE investors (as described below), an aggregate of
1,250,000
shares of Common Stock to vendors in connection with the Closing,
and Atlantic Coastal Acquisition Management II LLC (the "Sponsor") forfeited and New Abpro cancelled
966,442
shares of Common
Stock (further described below).
Under the Second Amended Articles of Incorporation
of ACAB dated November 12, 2024, each of the outstanding shares of ACAB Series A Common Stock and the outstanding share of ACAB Class
B Common Stock was exchanged into one share of Common Stock.
Unless otherwise defined herein, capitalized terms
used in this Quarterly Report on Form 10-Q have the same meaning as set forth in the Proxy Statement/Prospectus.
In connection with the Special Meeting, ACAB shareholders
holding
330,276
shares of ACAB's Series A common stock (the "Public Shares") (after giving effect to the share repurchases
by Yorkville as described below) exercised their right to redeem their shares for a pro rata portion of the funds in ACAB's trust
account (the "Trust Account"). Prior to the Closing approximately $
3,752,627
(approximately $
11.36
per Public Share) was removed
from the Trust Account to pay such holders.
Following the Closing, Abpro's stockholders
shall be issued up to
14,500,000
additional shares of the Post-Combination Company common stock ("Earnout Shares") if, within
five calendar years after the closing of the Business Combination, the volume weighted average price of shares of Series A Common Stock
on Nasdaq, or any other national securities exchange on which the shares of Series A Common Stock are then traded ("VWAP")
meets or exceeds three-tier target prices defined in the agreement, as follows:
a)
one-third of the total Earnout Shares, if, the VWAP is greater
than or equal to $
13.00
over any
20
trading days within any consecutive
30
trading day period (the "First Share Target")
b)
one-third of the total Earnout Shares, if, the VWAP is greater
than or equal to $
15.00
over any
20
trading days within any consecutive
30
trading day period (the "Second Share Target")
c)
one-third of the total Earnout Shares, if, the VWAP is greater
than or equal to $
18.00
over any
20
trading days within any consecutive
30
trading day period (the "Third Share Target").

NOTES
TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER

(UNAUDITED)
These shares are contingently issuable upon the
achievement of the set market performance targets. Considering the underlying contingent consideration to be transferred are common stocks,
and as such is indexed to the Post-Combination Company's own stock and classified in stockholders' equity in the statement
of financial position, we deemed the contingent payments under the earnout provisions to qualify for the scope exception in Accounting
Standards Codification ("ASC") 815-10-15-74(a). As a result, the contingent consideration obligation will be recognized when
the contingency is resolved, and the consideration is paid or becomes payable and has no impact on the pro forma condensed financial statements.
Abpro's
61,009
outstanding common stock warrants
expired upon the consummation of the Business Combination.
Concurrently with the execution of the BCA, Abpro
and Abpro Bio International, Inc. ("Abpro Bio"), an Abpro stockholder, entered into an agreement (the "Sponsor Share
Letter"), pursuant to which Sponsor agreed to, at the Closing Date, (i) retain
2,950,000
shares of Series A Common Stock of ACAB,
(ii) retain
291,667
shares, and transfer
983,333
shares to Abpro and
983,333
of the shares Abpro Bio ("Promote Shares"), for
such parties to use to obtain non-redemption commitments from SPAC stockholders or other capital for SPAC or the Surviving Corporation
(with any shares unused for such purpose to be retained by such party), and (iii) forfeit the remainder of any Series A Common Stock and
Series B Common Stock held by Sponsor (or
966,441
Series A shares and
1
Series B shares). It was also agreed in the Sponsor Share Letter
that the Sponsor will transfer
200,000
shares to one of ACAB's financial advisors for the services provided prior to the merger
date. The transfer of
983,333
shares of ACAB Series A Common Stock to Abpro Bio was reflected in the pro forma condensed financial statements
as a part of the recapitalization in conjunction with the Business Combination and this transfer has no financial impact. As it relates
to
983,333
shares transferred to Abpro, the corresponding issuance costs will be recorded at the date these shares are transferred to
third-party investors against non-redemption or capital commitments. If the
983,333
shares of Series A common stock held by Abpro and
291,667
shares held by the Sponsor are transferred to third-party investors in conjunction with their capital commitments, the maximum
related costs to be recorded to additional paid-in capital will be in the amount of approximately $
14.3
million (based on the fair value
of ACAB's common stock shares of $
11.20
per share at September 30, 2024) with the corresponding decrease in the paid-in-capital.
Under the terms of the BCA, at the Closing of
the Business Combination, the Sponsor received
600,601
shares of common stock of New Abpro in exchange for the extinguishment of $
2,000,000
advances to ACAB by the Sponsor.
On November 14, 2024, pursuant to the previously
disclosed Standby Equity Purchase Agreement ("SEPA") dated October 30, 2024 with YA II PN, LTD., New Abpro delivered a Convertible
Promissory Note to Yorkville ("Yorkville Note") for $
3,000,000
, and received net proceeds of $
2,755,000
. The Yorkville Note
has a maturity of November 13, 2025, incurs interest at a rate of
0
% (or
18
% upon the occurrence of an uncured Event of Default), and
is redeemable at the option of New Abpro if the VWAP of New Abpro's Common Stock is less than $
11.50
. Yorkville has a right to convert
any portion of the Yorkville Note at any time at a conversion price per share equal to the lower of (i)
94
% of the lowest daily VWAP during
the previous
5
consecutive trading days and (ii) $
11.50
, which may be adjusted downward upon payment of stock dividend, stock split or
reclassification, or if New Abpro issues Common Stock for no consideration or at a price lower than the then-effective Fixed Price (as
defined in the Yorkville Note).
Business Prior to the Business Combination
As of September 30, 2024, the Company had not
yet commenced any operations. All activity for the period May 20, 2021 (inception) through September 30, 2024 relates to the Company's
formation, the initial public offering (the "Initial Public Offering"), which is described below, and subsequent to the Initial
Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after
the completion of a Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income
from the proceeds derived from the Initial Public Offering.
The registration statement for the Company's
Initial Public Offering was declared effective on January 13, 2022. On January 19, 2022, the Company consummated the Initial
Public Offering of
30,000,000
units (the "Units" and, with respect to the shares of Series A common stock included in the
Units being offered, the "Public Shares"), which includes the partial exercise by the underwriters of its over-allotment option
in the amount of
3,900,000
Units at $
10.00
per Unit, generating gross proceeds of $
300,000,000
, which is described in Note 3.
Simultaneously with the closing of the Initial
Public Offering, the Company consummated the sale of
13,850,000
warrants (each, a "Private Placement Warrant" and, collectively,
the "Private Placement Warrants") at a price of $
1.00
per Private Placement Warrant in a private placement to Atlantic Coastal
Acquisition Management II LLC (the "Sponsor"), generating gross proceeds of $
13,850,000
, which is described in Note 4.

Following the closing of the Initial Public Offering
on January 19, 2022, an amount of $
306,000,000
($
10.20
per Unit) from the net proceeds of the sale of the Units in the Initial Public
Offering and the sale of the Private Placement Warrants was placed in a trust account (the "Trust Account"), to be invested
in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended
(the "Investment Company Act"), with a maturity of
185
days or less, or in any open-ended investment company that holds itself
out as a money market fund meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the
earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the funds in the Trust Account to the
Company's stockholders.
The
Company had

If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations
except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem
the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including
interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations (less up
to $
100,000
of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will
completely extinguish public stockholders' rights as stockholders (including the right to receive further liquidating distributions,
if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company's
remaining stockholders and the Company's board of directors, dissolve and liquidate, subject in each case to the Company's
obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption
rights or liquidating distributions with respect to the Company's warrants, which will expire worthless if the Company fails to
complete a Business Combination within the Combination Period. On April 18, 2023, the company held the Meeting to approve an extension
of time for the Company to consummate a Business Combination from April 19, 2023 to October 19, 2023, subject to additional
Extension(s) up to December 19, 2023 upon election by the Sponsor. The extension was approved and a result
26,564,308
shares
of the Company's Series A common stock were redeemed at approximately $
10.41
per share.
On
April 18, 2023, the Sponsor, the Company's independent directors, and Apeiron Investment Group Ltd (collectively, the "Series
B Holders") voluntarily converted
7,499,999
shares of Series B common stock of the Company they held as of such date into
7,499,999
shares of Series A common stock of the Company (the "Conversion") in accordance with the amended and restated certificate
of incorporation, as amended. With respect to shares of Series A common stock that they received as result of the Conversion, the Series
B Holders (i) agreed that they would not vote such stock until after the closing of a Business Combination and (ii) acknowledged
that such stock would not be entitled to any distribution from the Company's trust account. As a result of the Conversion and the
results of the Meeting described above, the Company has an aggregate of
10,935,691
shares of Series A common stock outstanding and
1
share of Series B common stock (held by the Sponsor) outstanding.
On
October 14, 2023 and November 14, 2023, the Company issued non-interest bearing, unsecured promissory notes in the aggregate
principal amount of $
80,000
, respectively, (the "Notes") to the Sponsor. The $
80,000
of proceeds was deposited into
the Company's trust account in order to extend the amount of time that the Company has available to complete a Business Combination.
Upon the closing of a Business Combination by the Company, the Sponsor may elect to either receive repayment under the Notes or to convert
all or a portion of the amount loaned under the Notes into Series A common stock of the Company at a price equal to $
10.20
per
share. In the event that the Company does not complete a Business Combination, the amounts loaned under the Notes will be repaid to the
Sponsor only from funds held outside the Trust Account or will be forfeited, eliminated, or otherwise forgiven.
On
October 14, 2023, by resolution of the board of directors of the Company, the Company extended the expiration date of the Combination
Period from October 19, 2023 to November 19, 2023.
On
November 14, 2023, by resolution of the board of directors of the Company, the Company extended the expiration date of the Combination

(UNAUDITED)
On December 15, 2023, the company held the
Meeting to approve an extension of time for the Company to consummate a Business Combination from December 19, 2023 to March 19,
2024, subject to deposits into the trust account maintained for the benefit of the Company's public stockholders the lesser of (a)
$
30,000
or (b) $
0.045

Business Combination by the Extended Date, the Company may, without another stockholder vote, elect to extend the Extended Date on a monthly
basis up to six times by an additional one month each time thereafter, until September 19, 2024. The extension was approved and a
result
2,768,301
public shares of Series A common stock exercised and did not reverse, their right to redeem their Public Shares in connection
with the vote upon the Charter Amendment Proposal. As a result of the foregoing, those holders will receive a payment of approximately
$
10.68
per share redeemed. This resulted in $
29,728,990
being withdrawn from the trust account and paid to redeeming stockholders. The
payment to the redeeming stockholders was processed in January 2024, as such $
29,728,990
has been removed from Series A common stock subject
to redemption and recorded as common stock to be redeemed.
On
January 21, 2024, the Company received a partial waiver from an underwriter from the initial public offering that was entitled to a portion

of the underwriter fee in exchange
for
600,000
of common stock in the post-merger Company.
On
January 22, 2024, the Company issued a press release announcing that it filed a Registration Statement on Form S-4 with the Securities
and Exchange Commission ("SEC") on January 19, 2024 in connection with the previously announced Merger.

Going
Concern and Liquidity
At September 30, 2024, the Company had $
13,597
in its operating bank accounts and a working capital deficit of $
7,480,594
.
In connection with the Company's assessment
of going concern considerations in accordance with the Financial Accounting Standards Board's ("FASB") Accounting Standards
Codification ("ASC") Topic 205-40 "Presentation of Financial Statements—Going Concern," management has determined
the future viability of the Company is largely dependent on its ability to raise additional capital to finance its operations. The Company
expects to seek additional funding through equity and debt financings, collaboration agreements and research grants. Although the Company
has been successful in raising capital in the past, there is no assurance that it will be successful in obtaining such additional financing
on terms acceptable to the Company, if at all. If the Company is unable to obtain funding, the Company could be forced to delay, reduce
or eliminate its research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect
its business prospects.
Accordingly, based on the considerations discussed above, management
has concluded there is substantial doubt as to the Company's ability to continue as a going concern within one year after the date
the condensed consolidated financial statements are issued. If adequate funds are not available, the Company may require initiating steps
to slow cash burn, extending the cash runway until financing can be secured. The unaudited condensed consolidated financial statements
do not include any adjustments with respect to the carrying amounts of assets and liabilities and their classification that might result
from the outcome of this uncertainty.
Risks
and Uncertainties
The
impact of current conflicts around the globe, including Russia's invasion of Ukraine and the Israel-Hamas war, and related sanctions,
on the world economy is not determinable as of the date of these financial statements, and the specific impact on the Company's
financial condition, results of operations, and cash flows is also not determinable as of the date of these financial statements.
Inflation
Reduction Act of 2022
On
August 16, 2022, the Inflation Reduction Act of 2022 (the "IR Act") was signed into federal law. The IR Act provides
for, among other things, a new U.S. federal
1
% excise tax on certain repurchases of stock by publicly traded U.S. domestic corporations
and certain U.S. domestic subsidiaries of publicly traded foreign corporations occurring on or after January 1, 2023. The excise tax
is imposed on the repurchasing corporation itself, not its shareholders from which shares are repurchased. The amount of the excise tax
is generally
1
% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating
the excise tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair
market value of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department
of the Treasury (the "Treasury") has been given authority to provide regulations and other guidance to carry out and prevent
the abuse or avoidance of the excise tax.
Any
redemption or other repurchase that occurs after December 31, 2022, in connection with a Business Combination, extension vote or
otherwise, may be subject to the excise tax. Whether and to what extent the Company would be subject to the excise tax in connection
with a Business Combination, extension vote or otherwise would depend on a number of factors, including (i) the fair market value
of the redemptions and repurchases in connection with a Business Combination, extension or otherwise, (ii) the structure of a Business
Combination, (iii) the nature and amount of any "PIPE" or other equity issuances in connection with a Business Combination
(or otherwise issued not in connection with a Business Combination but issued within the same taxable year of a Business Combination)
and (iv) the content of regulations and other guidance from the Treasury. In addition, because the excise tax would be payable by
the Company and not by the redeeming holder, the mechanics of any required payment of the excise tax have not been determined. The foregoing
could cause a reduction in the cash available on hand to complete a Business Combination and impact the Company's ability to complete
a Business Combination.
During the second quarter, the IRS issued final regulations with respect
to the timing and payment of the excise tax. Pursuant to those regulations, the Company would need to file a return and remit payment
for any liability incurred during the period from January 1, 2023 to December 31, 2023 on or before October 31, 2024. The Company
has filed the excise tax return and has engaged the IRS in determining a payment plan for the balance.

NOTE
2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis
of Presentation
The
accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally
accepted in the United States of America ("U.S. GAAP") for interim financial information and in accordance with the instructions
to Form 10-Q and Article 8 of Regulation S-X of the SEC. Certain information or footnote disclosures normally included in financial statements
prepared in accordance with U.S. GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial
reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position,
results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed consolidated financial statements
include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position,
operating results and cash flows for the periods presented.
The
accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company's Annual
Report on Form 10-K as filed with the SEC on March 29, 2024. The interim results for the three and nine months ended September
30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024 or for any future
periods.
Emerging
Growth Company
The
Company is an "emerging growth company," as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart
Our Business Startups Act of 2012 (the "JOBS Act"), and it may take advantage of certain exemptions from various reporting
requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not
being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley
Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from
the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments
not previously approved.
Further,
Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial
accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective
or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting
standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements
that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of
such extended transition period which means that when a standard is issued or revised and it has different application dates for public
or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies
adopt the new or revised standard. This may make comparison of the Company's financial statements with another public company which
is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult
or impossible because of the potential differences in accounting standards used.
Use
of Estimates
The
preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires the Company's management
to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses
during the reporting period.
Making
estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of
a condition, situation or set of circumstances that existed at the date of the unaudited condensed consolidated financial statements,
which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly,
the actual results could differ significantly from those estimates.
Principles
of Consolidation
The
accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary.
All significant intercompany balances and transactions have been eliminated in consolidation.

To
mitigate the risk of us being deemed to have been operating as an unregistered investment company (including under the subjective test

the U.S. government securities or money market funds held in the Trust Account and thereafter to hold all funds in the Trust Account
in cash (which may include demand deposit accounts) until the earlier of consummation of our Business Combination or liquidation.
Series
A Common Stock Subject to Possible Redemption
The
Company accounts for its Series A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480, "Distinguishing
Liabilities from Equity." Series A Common stock subject to mandatory redemption is classified as a liability instrument and is
measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that is either
within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company's
control) is classified as temporary equity. At all other times, common stock is classified as a component of stockholders' equity.
The Company's Series A common stock feature certain redemption rights that are considered to be outside of the Company's
control and subject to occurrence of uncertain future events. Accordingly, at September 30, 2024 and December 31, 2023, Series A
common stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders'
deficit section of the Company's unaudited condensed consolidated balance sheet.
The
Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable Series A common
stock to equal the redemption value at the end of each reporting period. Increases or decreases in the carrying amount of redeemable
Series A common Stock are affected by charges against additional paid-in capital and accumulated deficit.

of September 30, 2024 and December 31, 2023, there were
no
deferred offering costs recorded in the accompanying condensed consolidated
balance sheets respectively.
Concentration
of Credit Risk
Financial
instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution,
which, at times, may exceed the Federal Deposit Insurance Corporation coverage of $
250,000
. The Company has not experienced losses on
this account and management believes the Company is not exposed to significant risks on such account.
Income
Taxes
The
Company accounts for income taxes under ASC 740, "Income Taxes." ASC 740 requires the recognition of deferred tax assets
and liabilities for both the expected impact of differences between the unaudited condensed financial statements and tax basis of
assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carryforwards. ASC 740
additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax
assets will not be realized. As of September 30, 2024 and December 31, 2023, the Company's deferred tax
asset had
a full valuation allowance recorded against it. Our effective tax rate was
8.99
% and
186.87
% for the three months ended September
30, 2024 and 2023, respectively, and
3.48
% and
27.88
% for the nine months ended September 30, 2024 and 2023, respectively. The
effective tax rate differs from the statutory tax rate of
21
% for the three and nine months ended September 30, 2024 and 2023, due
to changes in the valuation allowance on the deferred tax assets, a prior year true up and non-deductible M&A costs.
While
ASC 740 identifies usage of an effective annual tax rate for purposes of an interim provision, it does allow for estimating individual
elements in the current period if they are significant, unusual or infrequent. Computing the effective tax rate for the Company is complicated
due to the potential impact of the timing of any Business Combination expenses and the actual interest income that will be recognized
during the year. The Company has taken a position as to the calculation of income tax expense in a current period based on ASC 740-270-25-3
which states, "If an entity is unable to estimate a part of its ordinary income (or loss) or the related tax (benefit) but is otherwise
able to make a reasonable estimate, the tax (or benefit) applicable to the item that cannot be estimated shall be reported in the interim
period in which the item is reported." The Company believes its calculation to be a reliable estimate and allows it to properly
take into account the usual elements that can impact its annualized book income and its impact on the effective tax rate. As such, the
Company is computing its taxable income (loss) and associated income tax provision based on actual results through September 30, 2024.
ASC
740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements and prescribes
a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected
to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination
by taxing authorities. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim
period, disclosure and transition.
The
Company recognizes accrued interest and penalties related to income taxes and unrecognized tax benefits as income tax expense. There
were
no
unrecognized tax benefits as of September 30, 2024 and December 31, 2023. During the three and nine months ended September
30, 2024, the Company's provision for income taxes include a $
3,224
true up for interest and penalties. The Company is currently
not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

The
Company has identified the United States as its only "major" tax jurisdiction. The Company is subject to income taxation
by major taxing authorities since inception. These examinations may include questioning the timing and amount of deductions, the nexus
of income among various tax jurisdictions and compliance with federal and state tax laws. The Company's management does not expect
that the total amount of unrecognized tax benefits will materially change over the next twelve months.
Net
(Loss) Income per Common Share
The
Company complies with accounting and disclosure requirements of FASB ASC Topic 260, "Earnings Per Share". Net (loss) income
per common stock is computed by dividing net (loss) income by the weighted average number of common stock outstanding for the period.
Accretion associated with the redeemable shares of Series A common stock is excluded from earnings per share as the redemption value
approximates fair value.
The
calculation of diluted (loss) income per share does not consider the effect of the warrants issued in connection with the (i) Initial
Public Offering, and (ii) the private placement since the exercise of the warrants is contingent upon the occurrence of future events.
The warrants are exercisable to purchase
28,850,000
Series A common stock in the aggregate. As of September 30, 2024 and 2023, the Company
did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into common stock and then
share in the earnings of the Company. As a result, diluted net (loss) income per common stock is the same as basic net (loss) income
per common stock for the periods presented.
The
following table reflects the calculation of basic and diluted net (loss) income per common stock (in dollars, except per share amounts):

Derivative Financial Instruments
The Company evaluated its financial
statements to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with
FASB ASC Topic 815, "Derivatives and Hedging." For derivative financial instruments that are accounted for as liabilities,
the derivative instrument is initially recorded at fair value on the grant date and re-valued at each reporting date, with changes in
the fair value reported in the statements of operations. The classification of derivative instruments, including whether such instruments
should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative assets and liabilities are
classified in the balance sheet as current or non-current based on whether or not net-cash settlement or conversion of the instruments
could be required within 12 months of the balance sheet date. The Company accounted for the warrants issued in connection with the Initial
Public Offering and the private placement as equity under the guidance at FASB ASC Topic 815.
Warrants
We account for warrants as either equity-classified
or liability-classified instruments based on an assessment of the warrant's specific terms and applicable authoritative guidance
in ASC 480 and ASC 815, "Derivatives and Hedging". The assessment considers whether the warrants are freestanding financial
instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements
for equity classification under ASC 815, including whether the warrants are indexed to our own ordinary shares, among other conditions
for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance
and as of each subsequent reporting period date while the warrants are outstanding. Based on our assessment of the guidance, our warrants
meet the criteria for equity classification and are recorded within stockholders' equity.
Share-based Compensation
The Company adopted ASC Topic 718,
"Compensation
—
Stock Compensation," guidance to account for its share-based compensation. It defines a
fair value-based method of accounting for an employee share option or similar equity instrument. The Company recognizes all forms of share-based
payments, including share option grants, warrants and restricted share grants, at their fair value on the grant date, which are based
on the estimated number of awards that are ultimately expected to vest. Share-based payments, excluding restricted shares, are valued
using a Black-Scholes option pricing model. Grants of share-based payment awards issued to nonemployees for services rendered have been
recorded at the fair value of the share-based payment, which is the more readily determinable value. The grants are amortized on a straight-line
basis over the requisite service periods, which is generally the vesting period. If an award is granted, but vesting does not occur, any
previously recognized compensation cost is reversed in the period related to the termination of service. Share-based compensation expenses
are included in costs and operating expenses depending on the nature of the services provided in the statements of operations.
Recent Accounting Standards
In December 2023, the FASB issued ASU
No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"), which will require the
Company to disclose specified additional information in its income tax rate reconciliation and provide additional information for reconciling
items that meet a quantitative threshold. ASU 2023-09 will also require the Company to disaggregate its income taxes paid disclosure by
federal, state and foreign taxes, with further disaggregation required for significant individual jurisdictions. ASU 2023-09 will become
effective for Annual periods beginning after December 15, 2024. The adoption of ASU 2023-09 will not have a material impact on the
Company's financial statements.
Management does not believe that any
other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company's
financial statements.

NOTE 3. INITIAL PUBLIC OFFERING
Pursuant to the Initial Public Offering,
the Company sold
30,000,000
Units, which include the partial exercise by the underwriters of their over-allotment option in the amount
of
3,900,000
units, at a purchase price of $
10.00
per Unit.
Each Unit consists of one share of the Company's Series A common stock
and one-half of one redeemable warrant ("Public Warrant").
Each Public Warrant entitles the holder to purchase
one
share of
Series A common stock at an exercise price of $
11.50
per whole share (see Note 7).
NOTE 4. PRIVATE PLACEMENT
Simultaneously with the closing of
the Initial Public Offering, the Sponsor purchased an aggregate of
13,850,000
Private Placement Warrants at a price of $
1.00
per Private
Placement Warrant, for an aggregate purchase price of $
13,850,000
, in a private placement. Each Private Placement Warrant is exercisable
to purchase one Series A common stock at a price of $
11.50
per share, subject to adjustments (see Note 7). A portion of the proceeds from
the Private Placement Warrants was added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does
not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Warrants will be
used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will
expire worthless.
NOTE 5. RELATED PARTY TRANSACTIONS
Founder Shares
On October 25, 2021, the Sponsor
paid $
25,000
to cover certain offering costs of the Company in consideration for
7,187,500
shares of Series B common stock (the "Founder
Shares").
On January 13, 2022, the Company effectuated a 1.044-for-1 stock split, resulting in an aggregate of
7,503,750
Founder Shares outstanding (see Note 7).
Due to the underwriters' election to partially exercise their overallotment option,
3,750
shares were forfeited.
The Sponsor, founders, executive officers
and directors have agreed, subject to certain limited exceptions, not to transfer, assign or sell any of the Founder Shares until one
year after the completion of a Business Combination that results in all of the Company's stockholders having the right to exchange
their Series A common stock for cash, securities, or other property (except with respect to permitted transferees). Notwithstanding
the foregoing, (x) if the last reported sale price of the Series A common stock equals or exceeds $
12.00
per share (as adjusted for
stock splits, stock dividends, reorganizations, recapitalizations and the like) for any
20
trading days within any
30
-trading day
period commencing at least
150
days after a Business Combination, or (y) the date on which the Company completes a liquidation, merger,
capital stock exchange or other similar transaction that results in all of the Company's stockholders having the right to exchange
their shares of common stock for cash, securities or other property, then such securities will be released from these restrictions. Any
permitted transferees would be subject to the same restrictions and other agreements of the founders with respect to any Founder Shares.
On October 25, 2021, the Sponsor
transferred
250,000
Founder Shares to five director nominees (
50,000
shares to each director nominee) for no consideration, to serve in
his or her capacity as an independent director of the Company. The Company assigned the number of shares of Series B common stock of the
Company, par value $
0.0001
per share. The transfer of the Founders Shares to five director nominees is within the scope of FASB ASC
Topic 718, "Compensation-Stock Compensation" ("ASC 718"). Under ASC 718, stock-based compensation associated with
equity-classified awards is measured at fair value upon the grant date and expensed when earned. Shares granted to these directors are
forfeited if their status as director is terminated for any reason prior to the date of a Business Combination and, as such, there
has been no stock-based compensation expense recognized in the accompanying financial statements.
On December 1, 2021, the Company
and Apeiron Investment Group Ltd. ("Apeiron") entered into an Agreement to which Apeiron will serve as an advisor to the Company
in connection with identifying one or more businesses with which the Company may effectuate a Business Combination. As consideration for
Apeiron's willingness to provide the service set forth in the Agreement, the Sponsor shall pay or transfer to Apeiron (or its designee)
on behalf of the Company anon-refundable fee in the form of
50,000
shares of the Company's Series B common stock ("Fee
Shares"). The transfer of the Founder Shares to Apeiron is not directly related to or in connection with the Initial Public Offering
and not within the scope of offering costs as defined in Note 2. The transfer of the Fee Shares is in the scope of FASB ASC Topic 718,
"Compensation-Stock Compensation" ("ASC 718"). Under ASC 718, stock-based compensation associated with equity-classified
awards is measured at fair value upon the grant date. The fair value of the
50,000
Fee Shares granted to Apeiron was $
362,500
or $
7.25
per share. The Founders Shares were granted subject to a performance condition (i.e., the closing date of the Initial Public Offering).
Compensation expense related to the Founders Shares is recognized only when the performance condition is probable of occurrence under
the applicable accounting literature in this circumstance. As of December 31, 2022, the Company recognized $
362,500
in the operations
as stock-based compensation expense as the Company determined that the performance condition has been met at the date of issuance/closing
of the Initial Public Offering.
On August 16, 2024, ACAB advanced Abpro $
103,000
in connection with a promissory note ("August note") entered into between
Abpro and Shahraab Ahmad on August 16, 2024 for expenses related to the Business Combination, whereas Shahraab Ahmad would receive repayment

Capital Loans. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust
Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans.
Up to $
1,500,000
of such Working Capital Loans may be convertible into additional warrants of the post-Business Combination entity
at a price of $
1.00
per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants. Prior
to the completion of the Business Combination, the Company does not expect to seek loans from parties other than the Sponsor or its
affiliates as the Company does not believe third parties will be willing to loan such funds and provide a waiver against any and all rights
to seek access to funds in the Trust Account. There are

, respectively, (the
"Extension Promissory Notes") to the Sponsor. The $
80,000
of cash proceeds was deposited into the Company's trust
account in order to extend the amount of time that the Company has available to complete a Business Combination. Upon the closing of a
Business Combination by the Company, the Sponsor may elect to either receive repayment under the Notes or to convert all or a portion
of the amount loaned under the Extension Promissory Notes into Series A common stock of the Company at a price equal to $
10.20
per
share. In the event that the Company does not complete a Business Combination, the amounts loaned under the Extension Promissory Notes
will be repaid to the Sponsor only from funds held outside the Trust Account or will be forfeited, eliminated, or otherwise forgiven.
As of September 30, 2024 and December 31, 2023, the Company owed $
160,000

shares were subject to forfeiture to the extent that the underwriters' over-allotment
option was not exercised in full or in part so that the Initial Stockholders will own
20
% of the Company's issued and outstanding
common stock after the Initial Public Offering (assuming Initial Stockholders do not purchase any Public Shares in the Initial Public
Offering). On January 13, 2022, the Company effectuated a
1.044-for-1

Holders of Series A common stock and
Series B common stock will vote together as a single class on all other matters submitted to a vote of stockholders, except as required
by law.
The shares of Series B common stock
will automatically convert into shares of Series A common stock concurrently or immediately following the consummation of a Business Combination,
on a one-for-one basis, subject to adjustment as provided herein. In the case that additional shares of Series A common stock, or equity-linked
securities, are issued or deemed issued in connection with a Business Combination, the number of shares of Series A common stock issuable
upon conversion of all Founder Shares will equal, in the aggregate,
20
% of the total number of shares of Series A common stock outstanding
after such conversion (after giving effect to any redemption of shares of Series A common stock by Public Stockholders), including the
total number of shares of Series A common stock, or deemed issued or issuable upon conversion or exercise of any equity-linked securities
or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of a Business Combination, excluding
any shares of Series A common stock or equity-linked securities exercisable for or convertible into shares of Series A common stock issued,
or to be issued, to any seller in a Combination and any Private Placement Warrants issued to the Sponsor, officers, or directors upon
conversion of Working Capital Loans, provided that such conversion of Founder Shares will never occur on a less than
one-for-one
basis.
Warrants —
As of
September 30, 2024 and December 31, 2023, there are
15,000,000
outstanding Public Warrants. Public Warrants may only be exercised
for a whole number of shares. No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will become
exercisable on the later of (a) 30 days after the consummation of a Business Combination or (b) 12 months from the closing of the Initial
Public Offering, provided in each case that there is an effective registration statement under the Securities Act covering the Series
A common stock issuable upon exercise of the warrants and a current prospectus relating to them is available (or the Company permits holders
to exercise their warrants on a cashless basis under the circumstances specified in the public warrant agreement) and such shares are
registered, qualified, or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder. The
Public Warrants will expire five years from the consummation of a Business Combination or earlier upon redemption or liquidation.
The Company will not be obligated to
deliver any Series A common stock pursuant to the exercise of a Public Warrant and will have no obligation to settle such Public Warrant
exercise unless a registration statement under the Securities Act covering the issuance of the Series A common stock issuable upon exercise
of the Public Warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations
with respect to registration. No warrant will be exercisable, and the Company will not be obligated to issue shares of Series A common
stock upon exercise of a warrant unless Series A common stock issuable upon such warrant exercise has been registered, qualified or deemed
to be exempt under the securities laws of the state of residence of the registered holder of the warrants.
The Company has agreed that as soon
as practicable, but in no event later than
20
business days after the closing of a Business Combination, it will use its commercially
reasonable efforts to file with the SEC a registration statement covering the issuance, under the Securities Act, of the Series A common
stock issuable upon exercise of the warrants. The Company will use its commercially reasonable efforts to cause the same to become effective
within
60
business days after the closing of a Business Combination and to maintain the effectiveness of such registration statement,
and a current prospectus relating thereto, until the expiration of the warrants in accordance with the provisions of the warrant agreement.
If any such registration statement has not been declared effective by the 60th business day following the closing of a Business Combination,
holders of the warrants will have the right, during the period beginning on the 61st business day after the closing of a Business Combination
and ending upon such registration statement being declared effective by the SEC, and during any other period when the Company fails to
have maintained an effective registration statement covering the issuance of the shares of Series A common stock issuable upon exercise
of the warrants, to exercise such warrants on a "cashless basis." Notwithstanding the above, if the shares of Series A common
stock are, at the time of any exercise of a warrant, not listed on a national securities exchange such that they satisfy the definition
of a "covered security" under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders
of Public Warrants who exercise their warrants to do so on a "cashless basis" in accordance with Section 3(a)(9) of the
Securities Act and, in the event the Company so elect, the Company will not be required to file or maintain in effect a registration statement,
but will use its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption
is not available.

Once the warrants become exercisable,
the Company may redeem the Public Warrants:
●
in
whole and not in part;
●
at
a price of $
0.01
per warrant;
●
upon
not less than 30 days' prior written notice of redemption given after the warrants become exercisable to each warrant holder;
and
●
if,
and only if, the reported last sale price of the Series A common stock equals or exceeds $
18.00
per share (as adjusted for stock
splits, stock dividends, reorganizations, recapitalizations and the like) for any
20
trading days within a
30
-trading day period
commencing once the warrants become exercisable and ending three business days before the Company sends the notice of redemption to the
warrant holders.
If and when the warrants become redeemable
by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for
sale under all applicable state securities laws.
If the Company calls the Public Warrants
for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a "cashless
basis," as described in the warrant agreement. The exercise price and number of shares of Series A common stock issuable upon exercise
of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization,
merger or consolidation. However, except as described below, the warrants will not be adjusted for issuance of Series A common stock at
a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the warrants. If the Company
is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account,
holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the
Company's assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.
In addition, if (x) the Company
issues additional shares of Series A common stock or equity-linked securities, for capital raising purposes in connection with the closing
of a Business Combination at an issue price or effective issue price of less than $
9.20
per share of Series A common stock (with such
issue price or effective issue price to be determined in good faith by the Company's board of directors, and, in the case of any
such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or its affiliates,
as applicable, prior to such issuance) (the "Newly Issued Price"), (y) the aggregate gross proceeds from such issuances represent
more than
60
% of the total equity proceeds, and interest thereon, available for the funding of a Business Combination on the date of the
completion of a Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Company's
Series A common stock during the
20
trading day period starting on the trading day after the day on which the Company completes a Business
Combination (such price, the "Market Value") is below $
9.20
per share, the exercise price of the warrants will be adjusted
(to the nearest cent) to be equal to
115
% of the greater of the Market Value and the Newly Issued Price, and the $
18.00
per share redemption
trigger price will be adjusted (to the nearest cent) to be equal to
180
% of the greater of the Market Value and the Newly Issued Price.
As of September 30, 2024 and December 31,
2023, there were
13,850,000
Private Placement Warrants, The Private Placement Warrants are identical to the Public Warrants underlying
the Units sold in the Initial Public Offering, except that the Private Placement Warrants (including the Series A common stock issuable
upon the exercise of the Private Placement Warrants) are not transferable, assignable or salable until 30 days after the completion of
a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants are exercisable on a cashless
basis and are non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement
Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be
redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.
NOTE 8. FAIR VALUE MEASUREMENTS
The Company
follows guidance in ASC 820 for its financial assets and liabilities that are re-measured and reported at fair value at each
reporting period, and non-financial assets and liabilities that are re-measured and reported at fair value at least annually.

The fair value of the Company's
financial assets and liabilities reflects management's estimate of amounts that the Company would have received in connection with
the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants
at the measurement date. In connection the with measuring the fair value of its assets and liabilities, the Company seeks to maximize
the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal
assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify
assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities:
Level 1:
Quoted
prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions
for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
Level 2:
Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar
assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.
Level 3:
Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability.
NOTE 9 — SUBSEQUENT EVENTS
The Company evaluated subsequent events
and transactions that occurred after the balance sheet date up to the date that the unaudited condensed consolidated financial statements
were issued. Based upon this review the Company did not identify any subsequent events, other than below, that would have required adjustment
or disclosure in the unaudited condensed consolidated financial statements.

dated December 11, 2023, amended by an amendment dated September 4, 2024, by and among ACAB, Abpro Merger Sub Corp., a Delaware corporation
and a wholly owned subsidiary of ACAB, and Abpro Corporation, following the approval at the special meeting of the shareholders of ACAB
held on November 7, 2024. On November 12, 2024, pursuant to the BCA, and as described in greater detail in the Company's final prospectus
and definitive proxy statement, which was filed with the SEC on October 18, 2024, Merger Sub merged with and into Abpro Corporation, with
Abpro Corporation surviving the merger as a wholly owned subsidiary of ACAB, and ACAB changed its name to Abpro Holdings, Inc. As consideration
for the Business Combination, New Abpro issued to or reserved for Abpro Corporation shareholders an aggregate of approximately
50,000,000
shares of New Abpro common stock, par value $
0.0001
per share, consisting of
39,413,500
shares of Common Stock issued to Abpro Corporation
shareholders, and
10,586,500
shares of Common Stock reserved for issuance in connection with certain Abpro Corporation rollover RSUs and

shares of Common Stock to the PIPE investors (as described below),
an aggregate of
1,250,000
shares of Common Stock to vendors in connection with the Closing, and Atlantic Coastal Acquisition Management
II LLC forfeited and New Abpro cancelled
966,442
shares of Common Stock.
Under the Second Amended Articles of Incorporation
of ACAB dated November 12, 2024, each of the outstanding shares of ACAB Series A Common Stock and the outstanding share of ACAB Class
B Common Stock was exchanged into one share of Common Stock.
Unless otherwise defined herein, capitalized terms
used in this Quarterly Report on Form 10-Q have the same meaning as set forth in the Proxy Statement/Prospectus.
In connection with the Special Meeting, ACAB shareholders
holding
330,276
shares of ACAB's Series A common stock (the "Public Shares") (after giving effect to the share repurchases
by Yorkville as described below) exercised their right to redeem their shares for a pro rata portion of the funds in ACAB's trust
account. Prior to the Closing approximately $
3,752,627
(approximately $
11.36
per Public Share) was removed from the Trust Account to pay
such holders.
Following the Closing, Abpro's stockholders
shall be issued up to
14,500,000
additional shares of the Post- Combination Company common stock if, within five calendar years after
the closing of the Business Combination, the volume weighted average price of shares of Series A Common Stock on Nasdaq, or any other
national securities exchange on which the shares of Series A Common Stock are then traded ("VWAP") meets or exceeds three-tier
target prices defined in the agreement, as follows:
a)
one-third of the total Earnout Shares, if, the VWAP is greater
than or equal to $
13.00
over any
20
trading days within any consecutive
30
trading day period (the "First Share Target")
b)
one-third of the total Earnout Shares, if, the VWAP is greater

trading day period (the "Second Share Target")
c)
one-third of the total Earnout Shares, if, the VWAP is greater
than or equal to $
18.00
over any
20
trading days within any consecutive
30
trading day period (the "Third Share Target").
These shares are contingently issuable upon the
achievement of the set market performance targets. Considering the underlying contingent consideration to be transferred are common stocks,
and as such is indexed to the Post-Combination Company's own stock and classified in stockholders' equity in the statement
of financial position, we deemed the contingent payments under the earnout provisions to qualify for the scope exception in Accounting
Standards Codification ("ASC") 815-10-15-74(a). As a result, the contingent consideration obligation will be recognized when
the contingency is resolved, and the consideration is paid or becomes payable and has no impact on the pro forma condensed financial statements.

Date,
(i) retain 2,950,000 shares of Series A Common Stock of ACAB, (ii) retain 291,667 shares, and transfer 983,333 shares to Abpro and

It was also
agreed in the Sponsor Share Letter that the Sponsor will transfer
200,000
shares to one of ACAB's financial advisors for the services
provided prior to the merger date. The transfer of
983,333
shares of ACAB Series A Common Stock to Abpro Bio was reflected in the pro

has no financial impact. As it relates to
983,333
shares transferred to Abpro, the corresponding issuance costs will be recorded at the
date these shares are transferred to third-party investors against non-redemption or capital commitments. If the
983,333
shares of Series
A common stock held by Abpro and
291,667
shares held by the Sponsor are transferred to third-party investors in conjunction with their
capital commitments, the maximum related costs to be recorded to additional paid-in capital will be in the amount of approximately $
14.3
million (based on the fair value of ACAB's common stock shares of $
11.20

Combination stockholders holding a total of

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING
FIRM
To the Stockholders and Board of Directors of
Atlantic Coastal Acquisition Corp. II
Opinion on the Financial Statements
We have audited the accompanying balance sheets of Atlantic Coastal
Acquisition Corp. II (the "Company") as of December 31, 2023 and 2022, the related statements of operations, stockholders'
deficit and cash flows for each of the two years in the period ended December 31, 2023, and the related notes (collectively referred
to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the
financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each
of the two years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United
States of America.
Explanatory Paragraph – Going Concern
The accompanying financial statements have been
prepared assuming that the Company will continue as a going concern. As described in Note 1 to the financial statements, the Company
is a Special Purpose Acquisition Corporation that was formed for the purpose of completing a merger, capital stock exchange, asset acquisition,
stock purchase, reorganization or other similar business combination with one or more businesses on or before April 19, 2024, subject
to deposits into the trust account maintained for the benefit of the Company's public stockholders of the lesser of (a) $30,000
or (b) $0.045 for each Public Share that is not redeemed in connection with the Meeting, or the Company may, without another stockholder
vote, elect to extend the business combination deadline on a monthly basis by an additional six months through September 19, 2024.
The Company entered into a business combination agreement with a business combination target on December 11, 2023 however, the completion
of this transaction is subject to the conditions noted above. These matters raise substantial doubt about the Company's ability
to continue as a going concern. Management's plans with regard to these matters are also described in Note 1. The financial statements
do not include any adjustments that may be necessary should the Company be unable to continue as a going concern.
Basis for Opinion
These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public
accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to
be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations
of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB.
Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are
free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an
audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control
over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control
over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material
misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures
included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation
of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

NOTE 1 — ORGANIZATION
AND PLAN OF BUSINESS OPERATIONS
Atlantic Coastal Acquisition Corp. II (the
"Company") is a blank check company incorporated in Delaware on May 20, 2021. The Company was formed for the purpose
of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination
with one or more businesses (the "Business Combination"). On November 30, 2023 the Company formed Abpro Merger Sub Corp. ("Merger
Sub"), a wholly owned subsidiary of the Company.
The Company is not limited to a particular
industry or sector for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company and,
as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.
As of December 31, 2023, the
Company had not yet commenced any operations. All activity for the period May 20, 2021 (inception) through December 31,
2023 relates to the Company's formation, the initial public offering (the "Initial Public Offering"), which is
described below, and subsequent to the Initial Public Offering, identifying a target company for a Business Combination. The Company
will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company will
generate non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering.
The registration statement for the Company's
Initial Public Offering was declared effective on January 13, 2022. On January 19, 2022, the Company consummated the Initial
Public Offering of
30,000,000
units (the "Units" and, with respect to the shares of Series A common stock included in the
Units being offered, the "Public Shares"), which includes the partial exercise by the underwriters of its over-allotment option
in the amount of
3,900,000
Units at $
10.00
per Unit, generating gross proceeds of $
300,000,000
, which is described in Note 3.
Simultaneously with the closing of the Initial
Public Offering, the Company consummated the sale of
13,850,000
warrants (each, a "Private Placement Warrant" and, collectively,
the "Private Placement Warrants") at a price of $
1.00
per Private Placement Warrant in a private placement to Atlantic Coastal
Acquisition Management II LLC (the "Sponsor"), generating gross proceeds of $
13,850,000
, which is described in Note 4.
Transaction costs amounted to $
17,204,107
,
consisting of $
5,760,000
of underwriting fees (net of $
240,000
reimbursed by the underwriters), $
10,500,000
of deferred underwriting fees,
and $
944,107
of other offering costs.
Following the closing of the Initial
Public Offering on January 19, 2022, an amount of $
306,000,000
($
10.20
per Unit) from the net proceeds of the sale of the Units
in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (the "Trust
Account"), to be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the
Investment Company Act of 1940, as amended (the "Investment Company Act"), with a maturity of
185
days or less, or in
any open-ended investment company that holds itself out as a money market fund meeting the conditions of Rule 2a-7 of the Investment
Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or
(ii) the distribution of the funds in the Trust Account to the Company's stockholders, as described below.
To mitigate the risk of us being deemed to
have been operating as an unregistered investment company (including under the subjective test of Section 3(a)(1)(A) of the Investment
Company Act), the Company instructed the Trustee in December 29, 2023 to liquidate the U.S. government securities or money market funds
held in the Trust Account and thereafter to hold all funds in the Trust Account in cash (which may include demand deposit accounts) until
the earlier of consummation of our Business Combination or liquidation.
F-
32
While the
Company's management has broad discretion with respect to the specific application of the cash held outside of the Trust
Account substantially all of the net proceeds from the Initial Public Offering and the sale of the Private Placement Warrants, which
are placed in the Trust Account are intended to be applied generally toward completing a Business Combination. There is no assurance
that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial
Business Combinations with one or more operating businesses or assets with a fair market value equal to at least
80
% of the net
assets held in the Trust Account (as defined below) (less any deferred underwriting commissions and taxes payable on interest earned
on the Trust Account) at the time of the signing a definitive agreement to enter a Business Combination. The Company will only
complete a Business Combination if the post-Business Combination company owns or acquires
50
% or more of the outstanding voting
securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register
as an investment company under the Investment Company Act.
The Company will provide its holders of the
outstanding Public Shares (the "public stockholders") with the opportunity to redeem all or a portion of their Public Shares
upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business
Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business
Combination or conduct a tender offer will be made by the Company, solely in its discretion. The public stockholders will be entitled
to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $
10.20
per Public
Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its
tax obligations). There will be no redemption rights upon the completion of a Business Combination with respect to the Company's
warrants.
The Company will proceed with a Business Combination
only if the Company has net tangible assets of at least $
5,000,001
either prior to or upon such consummation of a Business Combination
and, if the Company seeks stockholder approval, a majority of the shares voted are voted in favor of the Business Combination. If a stockholder
vote is not required by law and the Company does not decide to hold a stockholder vote for business or other reasons, the Company will,
pursuant to its Amended and Restated Certificate of Incorporation (the "Amended and Restated Certificate of Incorporation"),
conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission ("SEC") and file
tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is
required by law, or the Company decides to obtain stockholder approval for business or other reasons, the Company will offer to redeem
shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company
seeks stockholder approval in connection with a Business Combination, the holders of the Company's shares prior to the Initial Public
Offering (the "Initial Stockholders") have agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares
purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each public stockholder
may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or do not vote at all.
Notwithstanding the above, if the Company
seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Amended
and Restated Certificate of Incorporation provides that a public stockholder, together with any affiliate of such stockholder or any other
person with whom such stockholder is acting in concert or as a "group" (as defined under Section 13 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), will be restricted from redeeming its shares with respect to more
than an aggregate of
15
% or more of the Public Shares, without the prior consent of the Company.
The Initial Stockholders have agreed (a)
to waive their redemption rights with respect to their Founder Shares and Public Shares held by them in connection with the
completion of a Business Combination, (b) to waive their liquidation rights with respect to the Founder Shares if the Company fails
to complete a Business Combination prior to September 19, 2024 and (c) not to propose an amendment to the Amended and Restated
Certificate of Incorporation (i) to modify the substance or timing of the Company's obligation to allow redemption in
connection with the Company's Initial Business Combination or to redeem
100
% of its Public Shares if the Company does not
complete a Business Combination or (ii) with respect to any other provision relating to stockholders' rights or
pre-initial business combination activity, unless the Company provides the public stockholders with the opportunity to redeem their
Public Shares in conjunction with any such amendment.
F-
33
The Company had
15
months from the closing of the Initial Public Offering to complete a Business Combination (the "Combination Period"). If
the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all
operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days
thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the
Trust Account including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its
tax obligations (less up to $
100,000
of interest to pay dissolution expenses), divided by the number of then outstanding Public
Shares, which redemption will completely extinguish public stockholders' rights as stockholders (including the right to
receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption,
subject to the approval of the Company's remaining stockholders and the Company's board of directors, dissolve and
liquidate, subject in each case to the Company's obligations under Delaware law to provide for claims of creditors and the
requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the
Company's warrants, which will expire worthless if the Company fails to complete a Business Combination within the Combination
Period.
On April 18, 2023, the company held the
Meeting to approve an extension of time for the Company to consummate an initial business combination from April 19, 2023 to October 19,
2023, subject to additional Extension(s) up to December 19, 2023 upon election by the Sponsor. The extension was approved and a result
26,564,308
shares of the Company's Series A common stock were redeemed at approximately $
10.41
per share.
On April 18, 2023, the Sponsor, the Company's
independent directors, and Apeiron Investment Group Ltd (collectively, the "Series B Holders") voluntarily converted
7,499,999
shares of Series B Common Stock of the Company they held as of such date into
7,499,999
shares of Series A common stock of the Company
(the "Conversion") in accordance with the amended and restated certificate of incorporation, as amended. With respect to shares
of Series A common stock that they received as result of the Conversion, the Series B Holders (i) agreed that they would not vote
such stock until after the closing of a business combination and (ii) acknowledged that such stock would not be entitled to any distribution
from the Company's trust account. As a result of the Conversion and the results of the Meeting described above, the Company has
an aggregate of
10,935,691
shares of Series A common stock outstanding and
1
share of Series B Common Stock (held by the Sponsor) outstanding.
On October 14, 2023 and November 14,
2023, the Company issued non-interest bearing, unsecured promissory notes in the aggregate principal amount of $
80,000
, respectively,
(the "Notes") to the Sponsor. The $
80,000
was deposited into the Company's trust account in order to extend the amount
of time that the Company has available to complete a business combination. Upon the closing of a business combination by the Company,
the Sponsor may elect to either receive repayment under the Notes or to convert all or a portion of the amount loaned under the Notes
into Series A common stock of the Company at a price equal to $
10.20
per share. In the event that the Company does not complete a business
combination, the amounts loaned under the Notes will be repaid to the Sponsor only from funds held outside the Trust Account or will
be forfeited, eliminated, or otherwise forgiven.
On October 14, 2023, by resolution of
the board of directors of the Company, the Company extended the expiration date of the Business Combination Period from October 19,
2023 to November 19, 2023.
On November 14, 2023, by resolution of
the board of directors of the Company, the Company extended the expiration date of the Business Combination Period from November 19,
2023 to December 19, 2023.
On
December 11, 2023, the Company, Abpro Merger Sub Corp., a Delaware corporation, and Abpro Corporation, a Delaware corporation,
entered into a business combination agreement (the "Business Combination Agreement"). Please see the Form 8-K filed on
December 12, 2023 for more information on the terms of the Business Combination Agreement, which contains customary
representations and warranties, covenants, closing conditions, termination provisions and other terms relating to the Merger.
F-
34
On December 15, 2023, the company held
the Meeting to approve an extension of time for the Company to consummate an initial business combination from December 19, 2023
to March 19, 2024, subject to deposits into the trust account maintained for the benefit of the Company's public stockholders
the lesser of (a) $
30,000
or (b) $
0.045
for each Public Share that is not redeemed in connection with the Meeting. If the Company has
not consummated a Business Combination by the Extended Date, the Company may, without another stockholder vote, elect to extend the Extended
Date on a monthly basis up to six times by an additional one month each time thereafter, until September 19, 2024. The extension
was approved and a result
2,768,301
public shares of Series A common stock exercised and did not reverse, their right to redeem their
public shares in connection with the vote upon the Charter Amendment Proposal. As a result of the foregoing, those holders will receive
a payment of approximately $
10.68
per share redeemed. This resulted in $
29,728,990
being withdrawn from the trust account and paid to
redeeming stockholders. The payment to the redeeming stockholders was processed in January 2024, as such $
29,728,990
has been removed
form Series A common stock subject to redemption and recorded as common stock to be redeemed.
The Initial Stockholders have agreed to waive
their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination
Period. However, if the Initial Stockholders acquire Public Shares in or after the Initial Public Offering, such Public Shares will be
entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination
Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account
in the event the Company does not complete a Business Combination within in the Combination Period and, in such event, such amounts will
be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the
event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than
the Initial Public Offering price per Unit ($
10.00
).
In order to protect the amounts held in
the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party for services
rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a
transaction agreement, reduce the amount of funds in the Trust Account to below (1) $
10.20
per Public Share or (2) such lesser
amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the
value of the trust assets, in each case net of the interest which may be withdrawn to pay our taxes. This liability will not apply
with respect to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and
except as to any claims under the Company's indemnity of the underwriters of the Initial Public Offering against certain
liabilities, including liabilities under the Securities Act of 1933, as amended (the "Securities Act"). Moreover, in the
event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent
of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to
indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (except the
Company's independent registered public accounting firm), prospective target businesses or other entities with which the
Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies
held in the Trust Account. There is no assurance that the Company's plans to consummate the Business Combination will be
successful or successful within the Combination Period. The consolidated financial statements do not include any adjustments that
might result from the outcome of this uncertainty.
Going Concern
At December 31, 2023, the Company had
$
264,538
in its operating bank accounts and a working capital deficit of $
5,394,929
.
Until the consummation of a Business Combination,
the Company will be using the funds not held in the Trust Account for identifying and evaluating prospective acquisition candidates, performing
due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire,
and structuring, negotiating and consummating the Business Combination.
F-
35
The Company has incurred and expects to continue
to incur significant costs in pursuit of its acquisition plans. The Company will need to raise additional capital through loans or additional
investments from its Sponsor, shareholders, officers, directors, or third parties. The Company's officers, directors and Sponsor
may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their
sole discretion, to meet the Company's working capital needs. Accordingly, the Company may not be able to obtain additional financing.
If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could
include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead
expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at
all. If the Company is unable to complete the Business Combination because it does not have sufficient funds available, the Company will
be forced to cease operations and liquidate the Trust Account. These conditions raise substantial doubt about the Company's ability
to continue as a going concern one year from the date that these consolidated financial statements are issued.
In connection with the Company's
assessment of going concern considerations in accordance with the Financial Accounting Standards Board's ("FASB")
Accounting Standards Codification ("ASC") Topic 205-40 "Presentation of Financial Statements—Going
Concern," the Company has until April 19, 2024, 2023, to consummate a Business Combination. If a Business Combination is not
consummated by this date there will be a mandatory liquidation and subsequent dissolution of the Company. Although the Company
intends to consummate a Business Combination on or before April 19, 2024, it is uncertain that the Company will be able to
consummate a Business Combination by this time. Management has determined that the liquidity condition, coupled with the mandatory
liquidation, should a Business Combination not occur, and potential subsequent dissolution raise substantial doubt about the
Company's ability to continue as a going concern. The Company's plan is to complete a business combination on or prior
to April 19, 2024, however it is uncertain that the Company will be able to consummate a Business Combination by this time. No
adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after April
19, 2024.
Risks and Uncertainties
Management continues to evaluate the
impact of the COVID-19 pandemic and has concluded that while it is reasonably possible that the virus could have a negative effect
on the Company's financial position, results of its operations and/or search for a target company, close of the Initial Public
Offering, and/or search for a target company, the specific impact is not readily determinable as of the date of these financial
statements. The consolidated financial statements do not include any adjustments that might result from the outcome of this
uncertainty.
The impact of current conflicts around the
globe, including Russia's invasion of Ukraine and the Israel-Hamas war, and related sanctions, on the world economy is not determinable
as of the date of these financial statements, and the specific impact on the Company's financial condition, results of operations,
and cash flows is also not determinable as of the date of these financial statements.
Inflation Reduction Act of 2022
On August 16, 2022, the Inflation Reduction
Act of 2022 (the "IR Act") was signed into federal law. The IR Act provides for, among other things, a new U.S. federal
1
%
excise tax on certain repurchases of stock by publicly traded U.S. domestic corporations and certain U.S. domestic subsidiaries of
publicly traded foreign corporations occurring on or after
January 1, 2023
. The excise tax is imposed on the repurchasing corporation
itself, not its shareholders from which shares are repurchased. The amount of the excise tax is generally 1% of the fair market value
of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise tax, repurchasing corporations
are permitted to net the fair market value of certain new stock issuances against the fair market value of stock repurchases during the
same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department of the Treasury (the "Treasury")
has been given authority to provide regulations and other guidance to carry out and prevent the abuse or avoidance of the excise tax.
F-
36
Any redemption or other repurchase that occurs
after December 31, 2022, in connection with a Business Combination, extension vote or otherwise, may be subject to the excise tax.
Whether and to what extent the Company would be subject to the excise tax in connection with a Business Combination, extension vote or
otherwise would depend on a number of factors, including (i) the fair market value of the redemptions and repurchases in connection
with the Business Combination, extension or otherwise, (ii) the structure of a Business Combination, (iii) the nature and amount
of any "PIPE" or other equity issuances in connection with a Business Combination (or otherwise issued not in connection with
a Business Combination but issued within the same taxable year of a Business Combination) and (iv) the content of regulations and
other guidance from the Treasury. In addition, because the excise tax would be payable by the Company and not by the redeeming holder,
the mechanics of any required payment of the excise tax have not been determined. The foregoing could cause a reduction in the cash available
on hand to complete a Business Combination and impact the Company's ability to complete a Business Combination.
On April 18, 2023 and December 13,
2023, the Company's stockholders redeemed
26,564,308
Series Class A shares for a total of $
276,471,460
and redeemed
2,768,301
Series Class
A shares for a total of $
29,728,990
, respectively. The Company evaluated the classification and accounting of the stock redemption under
ASC 450, "Contingencies". ASC 450 states that when a loss contingency exists the likelihood that the future events will confirm
the loss or impairment of an asset or the incurrence of a liability can range from probable to remote. A contingent liability must be
reviewed at each reporting period to determine appropriate treatment. The Company evaluated the current status and probability of completing
a Business Combination as of December 31, 2023 and determined that a contingent liability should be calculated and recorded. As of
December 31, 2023, the Company recorded $
3,062,004
of excise tax liability calculated as 1% of shares redeemed.
NOTE 2 — SUMMARY OF
SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
The accompanying financial statements are
presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the United States of America
("U.S. GAAP") and pursuant to the accounting and disclosure rules and regulations of the SEC.
Emerging Growth Company
The Company is an "emerging growth company,"
as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the "JOBS
Act"), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies
that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public
accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive
compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote
on executive compensation and stockholder approval of any golden parachute payments not previously approved.
Further, Section 102(b)(1) of the
JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until
private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a
class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting
standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the
requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected
not to opt out of such extended transition period which means that when a standard is issued or revised and it has different
application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard
at the time private companies adopt the new or revised standard. This may make comparison of the Company's financial
statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted
out of using the extended transition period difficult or impossible because of the potential differences in accounting standards
used.
F-
37
Use of Estimates
The preparation of the consolidated financial
statements in conformity with U.S. GAAP requires the Company's management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements
and the reported amounts of revenues and expenses during the reporting period.
Making estimates requires management to exercise
significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances
that existed at the date of the consolidated financial statements, which management considered in formulating its estimate, could change
in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.
Principles of Consolidation
The accompanying consolidated financial statements
include the accounts of the Company and its wholly owned subsidiary. All significant intercompany balances and transactions have been
eliminated in consolidation.
Cash and Cash Equivalents
The Company considers all short-term investments
with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents
as of December 31, 2023 and 2022. The Company had $
264,538
and $
392,446
in cash at December 31, 2023 and 2022, respectively.
Cash and Marketable Securities Held
in Trust Account
At December 31, 2023 and 2022, all of
the Company's investments held in the Trust Account are invested in cash and money market funds invested primarily in United States
Treasuries and are classified as trading securities, respectively. Trading securities are presented on the consolidated balance sheet
at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of investments held in the
Trust Account are included in interest earned on marketable securities held in Trust Account in the accompanying statements of operations.
The estimated fair values of investments held in Trust Account are determined using available market information.
To mitigate the risk of us being deemed to
have been operating as an unregistered investment company (including under the subjective test of Section 3(a)(1)(A) of the Investment
Company Act), the Company instructed the Trustee in December 29, 2023 to liquidate the U.S. government securities or money market funds
held in the Trust Account and thereafter to hold all funds in the Trust Account in cash (which may include demand deposit accounts) until
the earlier of consummation of our Business Combination or liquidation.
Series A Common Stock Subject to Possible
Redemption
The Company accounts for its Series A common
stock subject to possible redemption in accordance with the guidance in ASC Topic 480, "Distinguishing Liabilities from Equity."
Series A Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally
redeemable common stock (including common stock that features redemption rights that is either within the control of the holder or subject
to redemption upon the occurrence of uncertain events not solely within the Company's control) is classified as temporary equity.
At all other times, common stock is classified as a component of stockholders' equity. The Company's Series A common stock
feature certain redemption rights that are considered to be outside of the Company's control and subject to occurrence of uncertain
future events. Accordingly, at December 31, 2023 and 2022, Series A common stock subject to possible redemption is presented at redemption
value as temporary equity, outside of the stockholders' deficit section of the Company's consolidated balance sheet.
F-
38
The Company recognizes
changes in redemption value immediately as they occur and adjusts the carrying value of redeemable Series A common stock to equal the
redemption value at the end of each reporting period. Increases or decreases in the carrying amount of redeemable Series A common Stock
are affected by charges against additional paid-in capital and accumulated deficit.
As of December 31, 2023 and 2022, the
Series A common stock reflected in the consolidated balance sheet are reconciled in the following table:

Deferred Offering Costs
The Company complies with the
requirements of the ASC 340-10-S99-1  and SEC Staff Accounting Bulletin ("SAB") Topic 5A—"Expenses
of Offering". Offering costs consist principally of professional and registration fees incurred through the balance sheet date
that are related to the Initial Public Offering. Offering costs are allocated based on the relative value of the Public and Private
Warrants to the proceeds received from the Public Shares sold in the Initial Public Offering. Offering costs allocated to the Public
Shares are charged to temporary equity and offering costs allocated to the Public and Private Warrants are charged to
stockholder's equity. As of January 19, 2022, offering costs in the aggregate of $17,204,107, of which an aggregate of
$16,699,058 have been charged to temporary equity and an aggregate of $505,049 have been charged to stockholders' equity.
As of December 31, 2023 and 2022, there
were no deferred offering costs recorded in the accompanying consolidated balance sheets respectively.
Concentration of Credit Risk
Financial instruments that potentially subject
the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal
Deposit Insurance Corporation coverage of $
250,000
. The Company has not experienced losses on this account and management believes the
Company is not exposed to significant risks on such account.
F-
39
Income Taxes
The Company accounts
for income taxes under ASC 740, "Income Taxes." ASC 740, requires the recognition of deferred tax assets and liabilities
for both the expected impact of differences between the financial statements and tax basis of assets and liabilities and for the expected
future tax benefit to be derived from tax loss and tax credit carryforwards. ASC 740 additionally requires a valuation allowance to be
established when it is more likely than not that all or a portion of deferred tax assets will not be realized. As of December 31,
2023 and 2022, the Company's deferred tax asset had a full valuation allowance recorded against it.
ASC 740 also
clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements and prescribes a
recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or
expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be
sustained upon examination by taxing authorities. ASC 740 also provides guidance on derecognition, classification, interest and
penalties, accounting in interim period, disclosure and transition. The Company recognizes accrued interest and penalties related to
unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and
penalties as of December 31, 2023 and 2022. The Company is currently not aware of any issues under review that could result in
significant payments, accruals or material deviation from its position.
The Company has identified the United
States as its only "major" tax jurisdiction. The Company is subject to income taxation by major taxing authorities since
inception. These examinations may include questioning the timing and amount of deductions, the nexus of income among various tax
jurisdictions and compliance with federal and state tax laws. The Company's management does not expect that the total amount
of unrecognized tax benefits will materially change over the next twelve months.
Net Income per Common Share
The Company complies with accounting and disclosure
requirements of FASB ASC Topic 260, "Earnings Per Share". Net income per common stock is computed by dividing net income by
the weighted average number of common stock outstanding for the period. Accretion associated with the redeemable shares of Series A common
stock is excluded from earnings per share as the redemption value approximates fair value.
The calculation of diluted income per share
does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, and (ii) the private
placement since the exercise of the warrants is contingent upon the occurrence of future events. The warrants are exercisable to purchase
28,850,000
Series A common stock in the aggregate. As of December 31, 2023 and 2022, the Company did not have any dilutive securities
or other contracts that could, potentially, be exercised or converted into common stock and then share in the earnings of the Company.
As a result, diluted net loss per common stock is the same as basic net income per common stock for the periods presented.

Fair Value of Financial Instruments
The fair value of the Company's assets
and liabilities, which qualify as financial instruments under ASC Topic 820, "Fair Value Measurement," approximates the carrying
amounts represented in the accompanying consolidated balance sheet, primarily due to their short-term nature.
Derivative Financial Instruments
The Company evaluated its financial
statements to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance
with FASB ASC Topic 815, "Derivatives and Hedging." For derivative financial instruments that are accounted for as
liabilities, the derivative instrument is initially recorded at fair value on the grant date and re-valued at each reporting date,
with changes in the fair value reported in the statements of operations. The classification of derivative instruments, including
whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period.
Derivative assets and liabilities are classified in the balance sheet as current or
non-current based on whether or not
net-cash settlement or conversion of the instruments could be required within 12 months of the balance sheet date. The Company
accounted for the warrants issued in connection with the Initial Public Offering and the private placement as equity under the
guidance at FASB ASC Topic 815.
Warrants
We account for warrants as either
equity-classified or liability-classified instruments based on an assessment of the warrant's specific terms and applicable
authoritative guidance in ASC 480 and ASC 815, "Derivatives a nd Hedging". The assessment considers whether the warrants
are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the
warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to our own
ordinary shares, among other conditions for equity classification. This assessment, which requires the use of professional judgment,
is conducted at the time of warrant issuance and as of each subsequent reporting period date while the warrants are outstanding.
Based on our assessment of the guidance, our warrants meet the criteria for equity classification and are recorded within
stockholders' equity.
F-
41
Share-based Compensation
The Company adopted ASC Topic 718,
"Compensation
—
Stock Compensation," guidance to account for its share-based compensation. It
defines a fair value-based method of accounting for an employee share option or similar equity instrument. The Company recognizes
all forms of share-based payments, including share option grants, warrants and restricted share grants, at their fair value on the
grant date, which are based on the estimated number of awards that are ultimately expected to vest. Share-based payments, excluding
restricted shares, are valued using a Black-Scholes option pricing model. Grants of share-based payment awards issued to
nonemployees for services rendered have been recorded at the fair value of the share-based payment, which is the more readily
determinable value. The grants are amortized on a straight-line basis over the requisite service periods, which is generally the
vesting period. If an award is granted, but vesting does not occur, any previously recognized compensation cost is reversed in the
period related to the termination of service. Share-based compensation expenses are included in costs and operating expenses
depending on the nature of the services provided in the statements of operations.
Recent Accounting Standards
In December 2023, the FASB issued ASU No.
2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"), which will require the Company
to disclose specified additional information in its income tax rate reconciliation and provide additional information for reconciling
items that meet a quantitative threshold. ASU 2023-09 will also require the Company to disaggregate its income taxes paid disclosure by
federal, state and foreign taxes, with further disaggregation required for significant individual jurisdictions. ASU 2023-09 will become
effective for Annual periods beginning after December 15, 2024. The Company is still reviewing the impact of ASU 2023-09.
In August 2020, the
FASB issued Accounting Standards Updated ("ASU") No. 2020-06, "Debt—Debt with Conversion and Other
Options (Subtopic470-20)and Derivatives and Hedging—Contracts in Entity's Own Equity(Subtopic 815-40):Accounting
for Convertible Instruments and Contracts in an Entity's Own Equity"("ASU 2020-06"),which simplifies
accounting for convertible instruments by removing major separation models required under current GAAP. ASU 2020-06 removes
certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, and it also
simplifies the diluted earnings per share calculation in certain areas. ASU 2020-06 is effective for fiscal years beginning
after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted. We are currently
assessing the impact, if any, that ASU 2020-06 would have on our financial position, results of operations or cash flows.
In June 2016, the FASB issued Accounting
Standards Update ("ASU") 2016-13–Financial Instruments – Credit Losses (Topic 326): Measurement of Credit
Losses on Financial Instruments ("ASU 2016-13"). This update requires financial assets measured at amortized cost
basis to be presented at the net amount expected to be collected. The measurement of expected credit losses is based on relevant
information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that
affect the collectability of the reported amount. Since June 2016, the FASB issued clarifying updates to the new standard including
changing the effective date for smaller reporting companies. The guidance is effective for fiscal years beginning after
December 15, 2022, and interim periods within those fiscal years, with early adoption permitted. The Company adopted ASU
2016-13 on January 1, 2023. The adoption of ASU2016-13 did not have a material impact on its financial statements.
Management does not believe that any other
recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company's
financial statements.
NOTE 3 — INITIAL
PUBLIC OFFERING
Pursuant to the Initial Public Offering,
the Company sold
30,000,000
Units, which include the partial exercise by the underwriters of their over-allotment option in the amount
of
3,900,000
units, at a purchase price of $
10.00
per Unit.
Each Unit consists of one share of the Company's Series A common stock
and one-half of one redeemable warrant ("Public Warrant").
Each Public Warrant entitles the holder to purchase
one
share
of Series A common stock at an exercise price of $
11.50
per whole share (see Note 7).
F-
42
NOTE 4 — PRIVATE
PLACEMENT
Simultaneously with the closing of the Initial
Public Offering, the Sponsor purchased an aggregate of
13,850,000
Private Placement Warrants at a price of $
1.00
per Private Placement
Warrant, for an aggregate purchase price of $
13,850,000
, in a private placement. Each Private Placement Warrant is exercisable to purchase
one Series A common stock at a price of $
11.50
per share, subject to adjustments (see Note 7). A portion of the proceeds from the Private
Placement Warrants was added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete
a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Warrants will be used to fund
the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless.
NOTE 5 — RELATED
PARTY TRANSACTIONS
Founder Shares
On October 25, 2021, the Sponsor
paid $
25,000
to cover certain offering costs of the Company in consideration for
7,187,500
shares of Series B common stock (the
"Founder Shares"). On January 13, 2022, the Company effectuated a
1.044-for-1
stock split, resulting in
an aggregate of
7,503,750
Founder Shares outstanding (see Note 7). Due to the underwriters' election to partially exercise
their overallotment option,
3,750
shares were forfeited.
The Sponsor,
founders, executive officers and directors have agreed, subject to certain limited exceptions, not to transfer, assign or sell any
of the Founder Shares until
one year
after the completion of a Business Combination that results in all of the Company's
stockholders having the right to exchange their Series A common stock for cash, securities, or other property (except with
respect to permitted transferees). Notwithstanding the foregoing, (x) if the last reported sale price of the Series A common
stock equals or exceeds $
12.00
per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the
like) for any

days after a Business Combination,
or (y) the date on which the Company completes a liquidation, merger, capital stock exchange or other similar transaction that
results in all of the Company's stockholders having the right to exchange their shares of common stock for cash, securities or
other property, then such securities will be released from these restrictions. Any permitted transferees would be subject to the
same restrictions and other agreements of the founders with respect to any Founder Shares.
On October 25,
2021, the Sponsor transferred
250,000
Founder Shares to five director nominees (
50,000
shares to each director nominee) for no consideration,
to serve in his or her capacity as an independent director of the Company. The Company assigned the number of shares of Series B common
stock of the Company, par value $
0.0001
per share. The transfer of the Founders Shares to five director nominees is within the scope
of FASB ASC Topic 718, "Compensation-Stock Compensation" ("ASC 718"). Under ASC 718, stock-based compensation
associated with equity-classified awards is measured at fair value upon the grant date and expensed when earned. Shares granted to these
directors are forfeited if their status as director is terminated for any reason prior to the date of the initial Business Combination and,
as such, there has been no stock-based compensation expense recognized in the accompanying financial statements.
On December 1,
2021, the Company and Apeiron Investment Group Ltd. ("Apeiron") entered into an Agreement to which Apeiron will serve as
an advisor to the Company in connection with identifying one or more businesses with which the Company may effectuate its Initial
Business Combination. As consideration for Apeiron's willingness to provide the service set forth in the Agreement, the
Sponsor shall pay or transfer to Apeiron (or its designee) on behalf of the Company a non-refundable fee in the form of
50,000
shares of the Company's Series B common stock ("Fee Shares"). The transfer of the Founder Shares to Apeiron is not
directly related to or in connection with the Initial Public Offering and not within the scope of offering costs as defined in Note
2. The transfer of the Fee Shares is in the scope of FASB ASC Topic 718, "Compensation-Stock Compensation" ("ASC
718"). Under ASC 718, stock-based compensation associated with equity-classified awards is measured at fair value upon the
grant date. The fair value of the
50,000
Fee Shares granted to Apeiron was $
362,500
or $
7.25
per share. The Founders Shares
were granted subject to a performance condition (i.e., the closing date of the Initial Public Offering). Compensation expense
related to the Founders Shares is recognized only when the performance condition is probable of occurrence under the applicable
accounting literature in this circumstance. As of December 31, 2022, the Company recognized $
362,500
in the operations as
stock-based compensation expense as the Company determined that the performance condition has been met at the date of
issuance/closing of the Initial Public Offering.

Promissory Note — Related Party
On October 25, 2021, the Sponsor
issued an unsecured promissory note to the Company (the "Promissory Note"), pursuant to which the Company may borrow up
to an aggregate principal amount of $
250,000
. The Promissory Note is non-interest bearing and is payable on the earlier of
April 30, 2022, or the consummation of the Initial Public Offering. As of December 31, 2023 and 2022, the Company has
no
outstanding balance under the Promissory Note, respectively.
Related Party Loans
In order to finance transaction costs in connection
with a Business Combination, the Sponsor has committed to advance the Company up to $
1,750,000
to fund the expenses relating to investigating
and selecting a target business and other working capital requirements after the Initial Public Offering and prior to the Initial Business
Combination. In addition, our Sponsor, or certain of our officers and directors or their affiliates may, but are not obligated to, loan
us additional funds as may be required. If the Company consummated an Initial Business Combination, the Company would repay the Working
Capital Loans. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust
Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans.
The final terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans.
Up to $
1,500,000
of such Working Capital Loans may be convertible into additional warrants of the post-Business Combination entity at
a price of $
1.00
per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants. Prior to
the completion of the Initial Business Combination, the Company does not expect to seek loans from parties other than the Sponsor or its
affiliates as the Company does not believe third parties will be willing to loan such funds and provide a waiver against any and all rights
to seek access to funds in the Trust Account. There are no Working Capital Loans outstanding as of December 31, 2023 and 2022.
Extension Promissory Notes — Related
Party
On October 14, 2023 and
November 14, 2023, the Company issued non-interest bearing, unsecured promissory notes in the principal amount of $
80,000
,
respectively, (the "Extension Promissory Notes") to the Sponsor. The $
80,000
was deposited into the Company's
trust account in order to extend the amount of time that the Company has available to complete a business combination. Upon the
closing of a business combination by the Company, the Sponsor may elect to either receive repayment under the Notes or to convert
all or a portion of the amount loaned under the Notes into Series A common stock of the Company at a price equal to $
10.20
per
share. In the event that the Company does not complete a business combination, the amounts loaned under the Notes will be repaid to
the Sponsor only from funds held outside the Trust Account or will be forfeited, eliminated, or otherwise forgiven. As of
December 31, 2023, the Company owed $
160,000
due under the Extension Promissory Notes with no further borrowings available.
On December 18, 2023, the Company amended
the Extension Promissory Notes to remove the Sponsor's right to convert the note into Series A common stock at a price equal to
$
10.20
per share.
Advance from Related Party
On December 8, 2023, December 11,
2023, and December 12, 2023, the Sponsor advanced the Company $
10,000
, $
1,630,000
, and $
15,000

Registration Rights
Pursuant to a registration rights
agreement entered into on January 13, 2022, the holders of the Founder Shares, Private Placement Warrants, and any Private
Placement Warrants that may be issued upon conversion of the Working Capital Loans (and any Series A common stock issuable upon the
exercise of the Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans and conversion
of Founder Shares) will be entitled to registration rights. The holders of these securities will be entitled to make up to three

"piggy-back" registration rights with respect to registration statements filed subsequent to the completion of a
Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the
Securities Act. However, the registration rights agreement provides that the Company will not be required to effect or permit any
registration or cause any registration statement to become effective until termination of the applicable lock-up period. The
registration rights agreement does not contain liquidated damages or other cash settlement provisions resulting from delays in
registering the Company's securities. The Company will bear the expenses incurred in connection with the filing of any such
registration statements.
Underwriting Agreement
The underwriters were entitled to a cash underwriting
discount of $
0.20
per Unit, or $
6,000,000
in the aggregate, paid on the closing of the Initial Public Offering. In addition, the underwriters
are entitled to a deferred fee of $
0.35
per Unit, or $
10,500,000
in the aggregate. The deferred fee will become payable to the underwriter
from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms
of the underwriting agreement.
Advisors
On January 7, 2022, the Company and Farvahar
Capital ("Farvahar") entered into an agreement under which Farvahar served as an advisor to the Company in connection with
the Initial Public Offering. Farvahar was engaged to represent the Company's interests only and is independent of the underwriters.
The underwriters reimbursed the Company for the fees payable to Farvahar in respect of the provision of such advisory services. The Company
agreed to pay Farvahar a fee of
0.08
% of the gross proceeds of the Initial Public Offering, including any exercise of the underwriters'
over-allotment option with respect to the Initial Public Offering or $
240,000
in the aggregate. Farvahar did not act as an underwriter
in connection with the Initial Public Offering; it did not identify or solicit potential investors in the Initial Public Offering. As
of December 31, 2022, the Company received the reimbursement from the underwriters and paid Farvahar.
Capital Market Advisor
On April 11, 2023, the Company entered
into a services agreement with an advisor. The Advisor will provide advisory services as it pertains to a business combination. Upon the
closing of a business combination the advisor will be paid a fee for their services. All consideration is to be paid simultaneously with
the closing of the business combination.

On or about April 4, 2023, the
Company and Atlantic Coastal Acquisition Management II LLC (the "Sponsor"), entered into agreements
("Non-Redemption Agreements") with several unaffiliated third parties in exchange for them agreeing not to redeem an

shares of the Company held by the Sponsor immediately following
consummation of an initial business combination if they continued to hold such Non-Redeemed Shares through the Meeting.

F-
47
The shares of Series B common stock will
automatically convert into shares of Series A common stock concurrently or immediately following the consummation of an Initial
Business Combination, on a one-for-one basis, subject to adjustment as provided herein. In the case that additional shares of Series
A common stock, or equity-linked securities, are issued or deemed issued in connection with the Initial Business Combination, the
number of shares of Series A common stock issuable upon conversion of all Founder Shares will equal, in the aggregate,
20
% of the
total number of shares of Series A common stock outstanding after such conversion (after giving effect to any redemption of shares
of Series A common stock by Public Stockholders), including the total number of shares of Series A common stock, or deemed issued or
issuable upon conversion or exercise of any equity-linked securities or rights issued or deemed issued, by the Company in connection
with or in relation to the consummation of the Initial Business Combination, excluding any shares of Series A common stock or
equity-linked securities exercisable for or convertible into shares of Series A common stock issued, or to be issued, to any seller
in the Initial Business Combination and any Private Placement Warrants issued to the Sponsor, officers, or directors upon conversion
of Working Capital Loans, provided that such conversion of Founder Shares will never occur on a less than
one-for-one basis.
Warrants —
As of December 31,
2023 and 2022, there are
15,000,000
outstanding Public Warrants. Public Warrants may only be exercised for a whole number of shares.
No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will become exercisable on the later of
(a)
30
days after the consummation of a Business Combination or (b)
12
months from the closing of the Initial Public Offering, provided
in each case that there is an effective registration statement under the Securities Act covering the Series A common stock issuable upon
exercise of the warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their warrants
on a cashless basis under the circumstances specified in the public warrant agreement) and such shares are registered, qualified, or
exempt from registration under the securities, or blue sky, laws of the state of residence of the holder. The Public Warrants will expire
five years from the consummation of a Business Combination or earlier upon redemption or liquidation.
The Company will not be obligated to deliver
any Series A common stock pursuant to the exercise of a Public Warrant and will have no obligation to settle such Public Warrant exercise
unless a registration statement under the Securities Act covering the issuance of the Series A common stock issuable upon exercise of
the Public Warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations
with respect to registration. No warrant will be exercisable, and the Company will not be obligated to issue shares of Series A common
stock upon exercise of a warrant unless Series A common stock issuable upon such warrant exercise has been registered, qualified or deemed
to be exempt under the securities laws of the state of residence of the registered holder of the warrants.
The Company has agreed that as soon as practicable,
but in no event later than 20 business days after the closing of a Business Combination, it will use its commercially reasonable efforts
to file with the SEC a registration statement covering the issuance, under the Securities Act, of the Series A common stock issuable upon
exercise of the warrants. The Company will use its commercially reasonable efforts to cause the same to become effective within
60
business
days after the closing of a Business Combination and to maintain the effectiveness of such registration statement, and a current prospectus
relating thereto, until the expiration of the warrants in accordance with the provisions of the warrant agreement. If any such registration
statement has not been declared effective by the
60
th business day following the closing of a Business Combination, holders of the warrants
will have the right, during the period beginning on the 61st business day after the closing of a Business Combination and ending upon
such registration statement being declared effective by the SEC, and during any other period when the Company fails to have maintained
an effective registration statement covering the issuance of the shares of Series A common stock issuable upon exercise of the warrants,
to exercise such warrants on a "cashless basis." Notwithstanding the above, if the shares of Series A common stock are, at
the time of any exercise of a warrant, not listed on a national securities exchange such that they satisfy the definition of a "covered
security" under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants
who exercise their warrants to do so on a "cashless basis" in accordance with Section 3(a)(9) of the Securities Act and,
in the event the Company so elect, the Company will not be required to file or maintain in effect a registration statement, but will use
its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not
available.
Once the warrants become exercisable, the
Company may redeem the Public Warrants:
●
in whole and not in part;
●
at a price of $
0.01
per warrant;
F-
48
●
upon not less than
30 days
' prior written notice of redemption given after the warrants become exercisable to each warrant holder; and
●
if, and only if, the reported last sale price of the Series A common stock equals or exceeds $
18.00
per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any
20
trading days within a
30
-trading day period commencing once the warrants become exercisable and ending three business days before the Company sends the notice of redemption to the warrant holders.
If and when the warrants become redeemable
by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for
sale under all applicable state securities laws.
If the Company calls the Public Warrants for
redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a "cashless
basis," as described in the warrant agreement. The exercise price and number of shares of Series A common stock issuable upon exercise
of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization,
merger or consolidation. However, except as described below, the warrants will not be adjusted for issuance of Series A common stock at
a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the warrants. If the Company
is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account,
holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the
Company's assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.
In addition, if (x) the Company issues
additional shares of Series A common stock or equity-linked securities, for capital raising purposes in connection with the closing of
a Business Combination at an issue price or effective issue price of less than $
9.20
per share of Series A common stock (with such issue
price or effective issue price to be determined in good faith by the Company's board of directors, and, in the case of any such
issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or its affiliates, as applicable,
prior to such issuance) (the "Newly Issued Price"), (y) the aggregate gross proceeds from such issuances represent more than
60
% of the total equity proceeds, and interest thereon, available for the funding of a Business Combination on the date of the completion
of a Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Company's Series A
common stock during the
20
trading day period starting on the trading day after the day on which the Company completes a Business Combination
(such price, the "Market Value") is below $
9.20
per share, the exercise price of the warrants will be adjusted (to the nearest
cent) to be equal to
115
% of the greater of the Market Value and the Newly Issued Price, and the $
18.00
per share redemption trigger price
will be adjusted (to the nearest cent) to be equal to
180
% of the greater of the Market Value and the Newly Issued Price.
As of December 31, 2023 and 2022,
there are
13,850,000
Private Placement Warrants, The Private Placement Warrants are identical to the Public Warrants underlying the
Units sold in the Initial Public Offering, except that the Private Placement Warrants (including the Series A common stock issuable
upon the exercise of the Private Placement Warrants) are not transferable, assignable or salable until
30
days after the completion
of an Initial Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants are
exercisable on a cashless basis and are non-redeemable so long as they are held by the initial purchasers or their permitted
transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees,
the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public
Warrants.

As of December 31, 2023 and 2022, the
Company did not have any U.S. federal and state net operating loss carryovers available to offset future taxable income.
In assessing the realization of the deferred
tax assets, management considers whether it is more likely than not that some portion of all of the deferred tax assets will not be realized.
The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which
temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred
tax liabilities, projected future taxable income and tax planning strategies in making this assessment. After consideration of all of
the information available, management believes that significant uncertainty exists with respect to future realization of the deferred
tax assets and has therefore established a full valuation allowance. For the year ended December 31, 2023 and 2022, the change in
the valuation allowance was $
298,330
and $
388,575
, respectively.

NOTE 9 — FAIR
VALUE MEASUREMENTS
The Company follows the guidance in ASC 820
for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period, and non-financial
assets and liabilities that are re-measured and reported at fair value at least annually.
The fair value of the Company's financial
assets and liabilities reflects management's estimate of amounts that the Company would have received in connection with the sale
of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the
measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of
observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions
about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities
based on the observable inputs and unobservable inputs used in order to value the assets and liabilities:
Level 1:
Quoted prices in active markets for identical assets or liabilities.
An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency
and volume to provide pricing in formation on an ongoing basis.
Level 2:
Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.
Level 3:
Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability.
The following table presents information about
the Company's assets that are measured at fair value on a recurring basis at December 31, 2023, and indicates the fair value
hierarchy of the valuation inputs the Company utilized to determine such fair value:

NOTE 10 — SUBSEQUENT
EVENTS
The Company evaluated subsequent events and
transactions that occurred after the balance sheet date up to the date that the consolidated financial statements were issued. Based upon
this review the Company did not identify any subsequent events that would have required adjustment or disclosure in the consolidated financial
statements.
On January 11, 2024, the Company
entered into an amended services agreement with and advisor, that was origin ally entered into on April 11 2023. The advisor will

disclosed on December 11, 2023 and as contemplated in the Business Combination Agreement, dated as of December 11, 2023, by

Organization
                                            and Description of the Business
Nature of
Operations
Abpro Corporation
(the "Company") founded in 2004, was incorporated under the laws of the State of Delaware. The Company is headquartered in
Woburn, Massachusetts.
The Company is a
biotechnology company dedicated to developing next-generation antibody therapeutics to improve the lives of patients with severe and life-threatening
diseases. The Company is focused on the development of novel antibodies using its proprietary discovery and engineering platforms, primarily
in the areas of immuno-oncology, ophthalmology and infectious disease.
Risks and Uncertainties
The Company is subject
to risks and uncertainties common to early-stage companies in the biotechnology industry, including, but not limited to, development by
competitors of more advanced or effective therapies, dependence on key executives, protection of and dependence on proprietary technology,
compliance with government regulations and ability to secure additional capital to fund operations. Programs currently under development
will require significant additional research and development efforts, including preclinical and clinical testing and regulatory approval
prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel and infrastructure, and
extensive compliance-reporting capabilities. Even if the Company's product development efforts are successful, it is uncertain when,
if ever, the Company will realize significant revenue from product sales.
Business Combination
Agreement
On November 13, 2024 (the "Closing
Date"), the Company consummated a business combination (the "Closing" of the "Business Combination") pursuant
to the terms of the Business Combination Agreement, dated as of December 11, 2023 (the "Business Combination Agreement") by
and among the Company, Atlantic Coastal Acquisition Corp. II, a Delaware corporation ("ACAB") and Abpro Merger Sub Corp.,
a Delaware corporation ("Merger Sub"). Pursuant to the Business Combination Agreement, on the Closing Date, (i) ACAB changed
its name to "Abpro Holdings, Inc.," ("New Abpro") and (ii) Merger Sub merged with and into the Company, with
the Company as the surviving company in the Business Combination. After giving effect to the Business Combination, the Company became
a wholly owned subsidiary of ACAB. Shares of New Abpro commenced trading on the Nasdaq Capital Market on November 14, 2024.
Immediately prior to the effective
time of the Business Combination, the Company's Preferred Shares that were issued and outstanding were converted into shares of
the New Abpro's common stock. As a result of the Business Combination, among other things, each share of the Company's common
stock, par value $0.001 per share, was converted into the right to receive the number of shares of newly issued ACAB Series A Common Stock
(the "ACAB New Common Shares"), par value $0.0001 per share, calculated based on the Exchange Ratio as set forth in the Business
Combination Agreement. The Company's common stock was exchanged for 39,123,200 shares of ACAB New Common Shares at the Closing Date.
Following the Closing, the Company's stockholders
shall be issued up to 14,500,000 additional shares of the Post-Combination Company common stock ("Earnout Shares") if, within
five calendar years after the closing of the Business Combination, the volume weighted average price of shares of Series A Common Stock
on Nasdaq, or any other national securities exchange on which the shares of Series A Common Stock are then traded ("VWAP")
meets or exceeds three-tier target prices defined in the agreement, as follows:
a)
one-third of the total Earnout Shares, if, the VWAP is greater
than or equal to $13.00 over any 20 trading days within any consecutive 30 trading day period (the "First Share Target")
b)
one-third of the total Earnout Shares, if, the VWAP is greater
than or equal to $15.00 over any 20 trading days within any consecutive 30 trading day period (the "Second Share Target")
c)
one-third of the total Earnout Shares, if, the VWAP is greater
than or equal to $18.00 over any 20 trading days within any consecutive 30 trading day period (the "Third Share Target").
If following the Closing, a Change of Control (as defined in the Business
Combination Agreement) occurs on or before the five year anniversary of the Closing Date, then if (i) the per share value of the consideration
to be received by stockholders in connection with the Change of Control exceeds $13.00 per share and the First Share Target has not been
previously achieved, then the First Share Target will be deemed to have been achieved, (ii) the per share value of the consideration to
be received by stockholders exceeds $15.00 per share and the Second Share Target has not been previously achieved, then the Second Share
Target will be deemed to have been achieved, and (iii) the per share value of the consideration to be received by stockholders exceeds
$18.00 per share and the Third Share Target has not been previously achieved, then the Third Share Target will be deemed to have been
achieved. Any Contingency Consideration that is not deemed to be earned in connection with the Change of Control shall be forfeited by
the stockholders for no consideration.
Pursuant to the terms of the Business
Combination Agreement, 600,601 shares of Series A common stock of New Abpro were issued at Closing to ACAB's sponsor, Atlantic Coastal
Management II LLC (the "Sponsor") in lieu of repayment of $2,000,000 of Unpaid SPAC Expenses (as defined in the Business Combination
Agreement) owed to the Sponsor as a result of advances made by the Sponsor to ACAB.
In connection with the Closing, ACAB's
articles of incorporation were amended to designate two classes of shares; preferred and common shares.

or advisor (the "NRA Investors"). Pursuant to such Non-Redemption Agreement, each NRA Investor agreed to rescind
or reverse any previously submitted redemption demand of the common stock of the Company held or to be acquired by such NRA Investor (the
"NRA Investor Shares") up to 124,352 shares of common stock in the aggregate.
At the Closing Date,
the NRA Investors reversed redemption demands with respect to 11,043 Series A Common stock shares. Pursuant to the Non-Redemption Agreement,
upon consummation of the Business Combination, ACAB shall pay or cause to be paid to the NRA Investors a payment in respect of their respective
NRA Investor Shares from cash released from the trust account established in connection with ACAB's initial public offering equal
to the number of NRA Investor Shares multiplied by the redemption price, minus the number of NRA Investor Shares multiplied by $9.00.
As such, New Abpro shall pay to the NRA Investors $26, based on the redemption price of $11.36 at the Closing Date.
Standby Equity
Purchase Agreement
On October 30,
2024, the Company and ACAB entered into a Standby Equity Purchase Agreement (the "SEPA") with YA II PN, Ltd. ("Yorkville").
Pre-Paid Advances
Subject to the satisfaction of the
conditions set forth in the SEPA, Yorkville shall advance to the post-combination Company the aggregate principal amount of $5,000 (the "Pre-Paid Advance"),
which shall be evidenced by convertible promissory notes (each a "SEPA Promissory Note"). On November 14, 2024, New Abpro
received the first Pre-Paid Advance and entered into the Yorkville Note (defined below). The second Pre-Paid Advance shall be
in a principal amount of $2,000 and advanced on the later of (i) the second trading day after the initial registration statement
filed pursuant to the Registration Rights Agreement (as defined below) becomes effective and (ii) the second trading day after the

has been obtained. At each Pre-Advance Closing, Yorkville shall advance to the post-combination Company the principal amount
of the Pre-Paid Advance, less a discount in an amount equal to 8% of the principal amount of the Pre-Paid Advance netted
from the purchase price due and structured as an original issue discount, in immediately available funds to an account designated by the
post-combination Company in writing, and the post-combination Company shall deliver a SEPA Promissory Note having a principal amount equal
to the full amount of such Pre-Paid Advance, duly executed on behalf of the post-combination Company.

57
On November 14, 2024, pursuant to the SEPA, New Abpro entered into
a Convertible Promissory Note ("Yorkville Note") for $3,000,000, and received net proceeds of $2,755,000. The Yorkville Note

any portion of the Yorkville Note at any time at a conversion price equal to the lower of $11.50, 94% of the daily VWAP during the previous
5 consecutive trading days, which may be adjusted downward upon payment of stock dividend, stock split or reclassification, or if New
Abpro issues Common Stock for no consideration or at a price lower than the then-effective Fixed Price (as defined in the Yorkville Note).
Advances
Upon the Closing of the Business Combination, the post-combination
Company has the right, but not the obligation, to issue shares of its common stock pursuant to the SEPA to Yorkville ("Advance Shares",
and such issuance and sale, an "Advance") and Yorkville shall subscribe for and purchase from the post-combination Company
such Advance Shares, through written notice by the post-combination Company to Yorkville ("Advance Notice"), provided (i) no
balance is outstanding under a SEPA Promissory Note, or (ii) if there is a balance outstanding under a SEPA Promissory Note, an Amortization
Event (as defined in the SEPA Promissory Note), has occurred in accordance with and subject to the terms of the SEPA. The post-combination
Company has the discretion to select the number of Advance Shares, not to exceed the Maximum Advance Amount (as defined below), that it
desires to issue and sell to Yorkville in each Advance Notice. If any amount remains outstanding under any SEPA Promissory Note, without
the prior written consent of Yorkville, the post-combination Company may only (other than with respect to a deemed Advance Notice pursuant
to an Investor Notice (described below)) submit an Advance Notice (A) if an Amortization Event has occurred and the obligation of the
post-combination Company to make monthly prepayments under the SEPA Promissory Note has not ceased, and (B) Yorkville pays the aggregate
purchase price owed to the post-combination Company from such Advance by offsetting the amount of the Advance Proceeds against an equal
amount outstanding under the subject SEPA Promissory Note, subject to the terms and conditions of the SEPA.
For as long as there
is an outstanding balance under a SEPA Promissory Note, Yorkville has the right, but not the obligation, by delivery to the post-combination
Company of Investor Notices (as defined in the SEPA), to cause an Advance Notice to be deemed delivered by Yorkville, which triggers the
issuance and sale of Advance Shares to Yorkville, subject to terms and conditions as specified in the SEPA.
"Maximum Advance Amount" means (A) in respect of each
Advance Notice delivered by the Company under the applicable provisions of the SEPA, an amount equal to one hundred percent (100%) of
the average of the daily traded amount of its shares of common stock during the five consecutive trading days immediately preceding an
Advance Notice, and (B) in respect of each Advance Notice deemed delivered by the Company pursuant to an Investor Notice, the amount
selected by Yorkville in such Investor Notice, which amount shall not exceed the limitations set forth in Section 3.02 of the SEPA,
including, among other things, (i) that all shares of the post-combination Company's common stock beneficially owned by Yorkville
and its affiliates shall not exceed 4.99% of the then outstanding voting power of the Company or number of shares of the Company's
common stock, (ii) that the aggregate number of shares issued and sold to Yorkville by the Company under the SEPA shall not exceed the
amount registered in respect of the transaction contemplated by the SEPA under the Registration Statement (as defined below) then in effect
and (iii) that the aggregate number of shares of common stock issued pursuant to the Pre-Paid Advances (including the aggregation with
the issuance of common stock under other Advances) cannot exceed 19.9% of the common stock of the post-combination Company outstanding
as of the effective date of the SEPA (the "Exchange Cap"). The Exchange Cap shall not be applicable if: (a) the post-combination
Company's stockholders have approved the issuance of common stock in excess of the Exchange Cap in accordance with the applicable
rules of Nasdaq Stock Market LLC ("Nasdaq") or (b) the average price of all sales of common stock under the SEPA equals or
exceed the lower of (i) the Nasdaq official closing price immediately preceding the effective date of the SEPA; or (ii) the average Nasdaq
official closing price for the five trading days immediately preceding the effective date. The SEPA contemplates purchase by Yorkville
of up to $50 million in aggregate gross purchase price for newly issued shares of the post-combination Company common stock.
The purchase price
for the Advance Shares shall be the price per Advance Share obtained by multiplying the Market Price (i) by 96% in respect of an
Advance Notice delivered by the Company with an Option 1 Pricing Period (defined by reference to VWAP on the trading day the Advance Notice
is submitted), (ii) 97% in respect of an Advance Notice with an Option 2 Pricing Period (defined by reference to the lowest daily VWAP
on three consecutive trading days commencing on the Advance Notice Date), or (iii) in the case of any Advance Notice delivered pursuant
to an Investor Notice, equal to the Conversion Price (as defined in the SEPA Promissory Note).

Registration
Rights Agreement
ACAB, Abpro and Yorkville also entered into a registration rights agreement
(the "Registration Rights Agreement"), dated October 30, 2024, pursuant to which the ACAB agreed to file with the Securities
and Exchange Commission a registration statement covering the resale of the applicable registrable securities under the Registration Rights
Agreement, including the Company's shares of common stock issuable to Yorkville under the SEPA. The SEPA, Registration Rights Agreement,
and the SEPA Promissory Note, and the documents executed in connection therewith, are referred to herein collectively as the "Financing
Agreements."
Forward Purchase Agreement
On November 7,
2024, ACAB and the Company entered into a Confirmation of an OTC Equity Prepaid Forward Transaction (the "Forward Purchase Agreement"
or "Transaction")) with Yorkville (the "Seller") to which a maximum of up to 500,000 Shares (as defined below)
(the "Maximum Number of Shares") will be subject. For purposes of the Forward Purchase Agreement, (i) ACAB is referred
to as the "Counterparty" prior to the consummation of the Business Combination, while New Abpro is referred to as the "Counterparty"
after the consummation of the Business Combination and (ii) "Shares" means shares of the Series A common stock, par value
$0.0001 per share, of the Company prior to the closing of the Business Combination ("ACAB Shares"), and, after the closing
of the Business Combination, shares of common stock, par value $0.0001 per share, of New Abpro ("New Abpro Shares"). At the
Closing Date, the Seller purchased 100,000 shares from third parties ("Recycled Shares"), pursuant to the pricing date notice
dated November 12, 2024. Pursuant to the terms of the Forward Purchase Agreement, on the Closing Date, the Seller paid approximately $1,100
(the "Prepayment Amount") equal to $11.36 per Recycled Share (the "Initial Price").
The number of Recycled
Shares subject to the Forward Purchase Agreement (being in no event more than the Maximum Number of Shares, the "Number of Shares")
is subject to reduction following a termination of the Forward Purchase Agreement with respect to such shares as described under "Optional
Early Termination" in the Forward Purchase Agreement.
The reset price (the
"Reset Price") will initially be $10.00. The Reset Price will be subject to reset on a weekly basis commencing with the first
full week following the Closing Date, to be the lowest of (a) the then current Reset Price, (b) $10.00 and (c) the VWAP Price
of the Shares of the last 3 trading days in such week; provided, that in the event of a Dilutive Offering by the Counterparty, the Reset
Price will also be reduced to equal the effective price per share in such Dilutive Offering immediately upon the occurrence of such Dilutive
Offering. Furthermore, in the event that the Counterparty engages in a stock split, a reverse stock split or pays dividends in the form
of Shares, the Reset Price shall be adjusted to reflect the effect thereof.
From time to time
and on any date following the Trade Date (any such date, an "OET Date") and subject to the terms and conditions in the Forward
Purchase Agreement, the Seller may, in its absolute discretion, terminate the Transaction in whole or in part by providing written notice
to the Counterparty (the "OET Notice"), by no later than the next Payment Date following the OET Date, (which will specify
the quantity by which the Number of Shares will be reduced (such quantity, the "Terminated Shares")). The effect of an OET
Notice will be to reduce the Number of Shares by the number of Terminated Shares specified in such OET Notice with effect as of the related
OET Date. As of each OET Date, the Counterparty will be entitled to an amount from the Seller, and the Seller will pay to the Counterparty
an amount, equal to the product of (x) the number of Terminated Shares and (y) the Reset Price in respect of such OET Date.
The payment date may be changed within a month at the mutual agreement of the parties.
The
"Valuation Date" is the earliest to occur of (a) the date that is 3 months after the Closing Date and (b) the date
specified by the Seller in a written notice to be delivered to the Counterparty at the Seller's discretion (which Valuation Date
will not be earlier than the day such notice is effective) after the occurrence of any of (x) a VWAP Trigger Event, (y) a Delisting
Event or (z) unless otherwise specified therein, upon any Additional Termination Event (defined below). The Valuation Date notice
will become effective immediately upon its delivery from the Seller to the Counterparty in accordance with the Forward Purchase Agreement.
Each of the following constitute an Additional Termination Event; (a) The Business Combination Agreement is terminated pursuant to its
terms prior to the closing of the Business Combination; and (b) If it is, or, as a consequence of a change in law, regulation or interpretation,
it becomes or will become, unlawful for the Seller to perform any of its obligations contemplated by the Transaction.
On the Cash Settlement
Payment Date, which is the tenth local business day immediately following the last day of the Valuation Period, the Seller will remit
to the Counterparty a cash amount (the "Settlement Amount") equal to (i) the Number of Shares as of the Valuation Date,
multiplied by (ii) the difference of (a) the volume weighted daily VWAP Price over the Valuation Period, less (b) $0.50, and
the Seller will not otherwise be required to return to the Counterparty any of the Prepayment Amount. In the event that the difference
of (a) the volume weighted daily VWAP Price over the Valuation Period, less (b) $0.50, is equal to or less than $0, then the Settlement
Amount shall be $0.
F-
59
The Seller has agreed
to waive any redemption rights with respect to any Recycled Shares in connection with the Business Combination only during the term of
the Forward Purchase Agreement. Such waiver may reduce the number of Shares redeemed in connection with the Business Combination, and
such reduction could alter the perception of the potential strength of the Business Combination.
Severance Agreement
On November 21, 2024, the Company entered
into a severance agreement with an executive of the post-combination Company (the "Severance Agreement"). Pursuant to the
terms of the Severance Agreement, the Company made a severance payment of $221 upon execution of the agreement. The Severance Agreement
supersedes and extinguishes all other agreements between the executive and the Company including, but not limited to, the ACAB Executive
Note (see Note 8).
Going Concern
The Company is required
to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt abouts its ability to continue
as a going concern within one year after the date that the condensed consolidated financial statements are available to be issued. Through
September 30, 2024, the Company has funded its operations mainly through equity and debt financings, and to a lesser extent, payments
received in connection with collaboration and license agreements.
Since inception,
the Company has incurred recurring losses. The Company's net losses totaled $3,897 and $7,887 for the nine months ended September
30, 2024 and 2023, respectively. The Company had an accumulated deficit of $109,468 as of September 30, 2024. The Company expects to incur
operating losses for the foreseeable future.
On
October 18, 2023, the Company entered into a promissory note agreement with
ABI, a significant investor in the Company's
Series E and F convertible preferred stock (See Note 8), to receive up to $6,000. The Company received $5,225 through the date of issuance
of these condensed consolidated financial statements under this promissory note, including $2,783 during the nine months ended September
30, 2024 (see Note 8 for terms and conditions).
On April 18, 2024, the Company entered
into a promissory note agreement with one of its executives (See Note 8 for terms and conditions) to receive, as amended, up to $2,158
in funding. The Company received $1,997 through the date of issuance of these unaudited condensed consolidated financial statements under
this promissory note, including $1,991 during the nine months ended September 30, 2024.
On
August 16, 2024, an executive at ACAB agreed to loan the Company $103 and the Company agreed to repay a total of $206 at the earlier
of i) November 20, 2024, and ii) the closing of the Business Combination.
On November 21, 2024, the ACAB Executive Note was
amended and the liability to the ACAB executive was cancelled. According to the terms of the amended note, the Company will repay
the principal amount of $103. See Note 8.
On
October 7, 2024, the Company entered into an additional promissory note with ABI ("the 2024 ABI Note") to receive up to $1,000
from ABI in weekly installment of $250. The note accrues 10% interest and matures 5 business days after receipt of the proceeds under
the PIPE Subscription Agreements.
The Company received $1,000 under this note as of the Closing Date, and the balance of $1,000
was repaid in connection with the Closing.
In connection with
the Closing of the Business Combination, the Company received approximately $2,300.
The future viability
of the Company is largely dependent on its ability to raise additional capital to finance its operations. The Company expects to seek
additional funding through equity and debt financings, collaboration agreements and research grants. Although the Company has been successful
in raising capital in the past, there is no assurance that it will be successful in obtaining such additional financing on terms acceptable
to the Company, if at all. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or eliminate its research
and development programs, product portfolio expansion or commercialization efforts, which could adversely affect its business prospects.
Accordingly, based
on the considerations discussed above, management has concluded there is substantial doubt as to the Company's ability to continue
as a going concern within one year after the date the condensed consolidated financial statements are issued. The Company plans to continue
to fundraise, as well as seek alternate revenues from collaboration and license agreements. If adequate funds are not available, the Company
may require initiating steps to slow cash burn, extending the cash runway until financing can be secured. The unaudited condensed consolidated
financial statements do not include any adjustments with respect to the carrying amounts of assets and liabilities and their classification
that might result from the outcome of this uncertainty.

Summary of Significant
                                            Accounting Policies
For the nine months ended September 30,
2024, there have been no changes to the significant accounting policies as disclosed in Note 2 to the Consolidated Financial Statements
included in the Company's consolidated financial statements for the year ended December 31, 2023.
Basis of Presentation
The condensed consolidated
financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S.
GAAP") and the applicable rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Certain information
or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant
to the rules and regulations of the SEC for interim financial reporting. These financial statements should be read in conjunction with
the Company's audited financial statements for the year ended December 31, 2023. The accompanying unaudited condensed financial
statements include all adjustments that are of a normal recurring nature and necessary for the fair presentation of the results for the
interim periods presented. Results for interim periods are not necessarily indicative of results to be expected for the full year.
The accompanying
condensed consolidated financial statements include all of the accounts of the Company and its subsidiary, AbMed Corporation ("AbMed").
All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates
The preparation
of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the
amounts reported in the consolidated financial statements and accompanying notes. Significant estimates in these consolidated financial
statements include stock-based compensation expense, fair value of common stock, revenue allocated to various performance obligations
under license and collaboration agreements, pre-clinical and clinical accrued expenses, discount rates in relation to lease right-of-use assets
and liabilities, valuation and realizability of deferred tax assets and the ability to continue as a going concern. On an ongoing basis,
the Company evaluates its estimates, judgments, and methodologies. The Company bases its estimates on historical experience and on various
other assumptions believed to be reasonable. Due to the inherent uncertainty involved in making estimates, actual results could differ
materially from those estimates.
In March 2022, the
Company received an invoice from Mabwell (Shanghai) Bioscience Co., Ltd. ("Mabwell") for approximately $3,500 in connection
with the manufacturing of certain clinical material for the Company. The Company recorded the estimated amount in accounts payable based
on the information available at the time, and subsequently engaged in discussion with Mabwell about the invoiced amount and its validity.
The Company continued to dispute the amount and its contractual basis because the parties had neither finalized nor executed a clinical
trial manufacturing agreement. In July 2024, the Company received communication from Mabwell that they will not be pursuing the collection
of the originally invoiced amount. Accordingly, during the nine months ended September 30, 2024, the Company reversed the liability and
recognized approximately $3,500 of other income.
Deferred Offering
Costs
Deferred offering
costs consist of legal, accounting, underwriting fees and other costs that are directly related to the Business Combination. These costs
will be accounted for as a reduction of proceeds received at the Closing Date. As of September 30, 2024 and December 31, 2023, the Company
had deferred offering costs of $1,817 and $878.
Non-controlling
Interest
The Company holds
an 82% ownership interest in its consolidated subsidiary, AbMed. Non-controlling interest represents the portion of net book value in
AbMed that is not owned by the Company and is reported as a component in stockholders' equity on the condensed consolidated balance
sheets. The Company bears all the operating costs of AbMed. Upon an event of default by the Company or upon a liquidation of AbMed, the
non-controlling interest holder has the right to put its interest in AbMed to the Company. The amount to be paid under the redemption
option is equal to $2.00 per share for each preferred share of AbMed stock held by the non-controlling interest holder plus all accrued
and unpaid dividends thereon. The Company has not allocated any losses to the noncontrolling interests given that the preferred shares
held by the non-controlling interest holder have no contractual obligations to share in the losses of AbMed. There were no operating activities
in AbMed during the nine months ended September 30, 2024 and 2023.
F-
61
Net Loss Per
Share
The Company follows
the two-class method to compute basic and diluted net loss per share attributable to common stockholders when shares meet the definition
of participating securities. Series A, Series B, Series C, Series D, Series E and Series F (see Note 9) meet the definition of participating
securities. The two-class method determines net income loss per common share for each class of common and participating securities according
to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income available
to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to
share in the earnings as if all income for the period had been distributed. During periods of loss, there is no allocation required under
the two-class method due to there being no distributed earnings for the period coupled with the fact that the Company's Series A,
Series B, Series C, Series D, Series E and Series F do not contain a contractual right to absorb losses. Thus, all undistributed losses
were allocated entirely to the Company's outstanding common stock for all periods presented.
Basic net loss per
share attributable to common stockholders is computed by dividing net loss attributable to common stockholders by the weighted-average
number of common shares outstanding during the period without consideration of potentially dilutive common stock. Diluted net loss per
share attributable to common stockholders reflects the potential dilution that could occur if securities or other contracts to issue common
stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the
Company unless inclusion of such shares would be anti-dilutive. As the Company has incurred losses for the nine months ended September
30, 2024 and 2023, basic and diluted net loss per share is the same for each period.
The following table
presents the potentially dilutive shares that were excluded from the computation of diluted net loss per share of common stock attributable
to common stockholders, because their effect was anti-dilutive:

Segment Reporting
The Company conducts
its business activities and reports financial results as one operating segment and one reportable segment, which is consistent with the
Company structure and the way the Company operates its business.
Recently Issued Accounting
Pronouncements
In December 2023, the Financial
Accounting Standards Board ("FASB") issued ASU 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures,"
that addresses requests for improved income tax disclosures from investors that use the financial statements to make capital allocation
decisions. Public entities must adopt the new guidance for fiscal years beginning after December 15, 2024. The amendments in this ASU
must be applied on a retrospective basis to all prior periods presented in the financial statements and early adoption is permitted. The
Company is currently evaluating the potential impact that the adoption of this standard will have on its financial statements.
F-
62
In November 2023, FASB issued Accounting
Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures to improve
disclosure requirements about reportable segments and address requests from investors for additional, more detailed information about
a reportable segment's expenses. This ASU requires that a public entity that has a single reportable segment provide all the disclosures
required by the amendments in this ASU and all existing segment disclosures in Topic 280. Additionally, this ASU requires disclosures
of significant segment expenses provided to the Chief Operating Decision Maker ("CODM") and included in reported measures of
segment profit and loss. Disclosure of the title and position of the CODM is required. This ASU requires interim and annual disclosures
about a reportable segment's profit or loss and assets. Furthermore, this ASU requires disclosure of other segment items by reportable
segment including a description of its composition. This ASU is effective for fiscal years beginning after December 15, 2023, and interim
periods within fiscal years beginning after December 15, 2024, on a retrospective basis. The disclosures will be implemented as required
for the year-ended December 31, 2024. The Company is currently evaluating the impact of adopting this standard on its financial statements.
On November 4, 2024, the FASB issued ASU
2024-03, Accounting Standards Update 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic
220-40): Disaggregation of Income Statement Expenses to improve financial reporting by requiring that public business entities disclose
additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods.
The amendments in this ASU do not change or remove current expense disclosure requirements; however, the amendments affect where such
information appears in the notes to financial statements because entities are required to include certain current disclosures in the same
tabular format disclosure as the other disaggregation requirements in the amendments. This ASU is effective for annual reporting periods
beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company
is currently evaluating the potential impact that the adoption of this standard will have on its financial statements.
Management does not believe that any
additional recently issued, but not yet effective, accounting standards, if currently adopted, would have a material impact on the Company's
unaudited condensed financial statements.

License and Collaboration Agreements
NJCTTQ Collaboration
Agreement
In
January 2019, the Company entered into a collaboration agreement with Nanjing Chia Tai Tianquing Pharmaceutical Co., Ltd. ("NJCTTQ")
to research, develop and commercialize two anti-Claudin 18.2 lead antibodies (the "NJCTTQ agreement"). Under the NJCTTQ agreement,
the Company granted a non-exclusive, non-sublicensable research license and an exclusive, sublicensable license to NJCTTQ within the People's
Republic of China and Thailand (the "NJCTTQ Territory").
The initial term of this agreement was 5 years, which could
be automatically renewed for another 5 years. If no collaboration project reached the clinical stage within the first 5 years of the NJCTTQ
agreement, then this agreement would not have been renewed. The agreement expired in January 2024.
The Company is eligible
to receive up to an aggregate of $405,000 of non-refundable milestone payments from NJCTTQ upon achieving certain development, regulatory
approval, and commercialization and sales milestones for each unique licensed antibody or product in NJCTTQ Territory. The Company agreed
to pay NJCTTQ up to an aggregate of $5,000 in nonrefundable amounts upon achieving of a regulatory milestone in the Company's territory,
which includes all other countries other than the NJCTTQ Territory. No
milestones have been reached
through the expiration of this agreement in January 2024, no products were sold by NJCTTQ, and no related revenue amounts have been recorded
in the accompanying consolidated financial statements.
The
Company and NJCTTQ agreed to pay reciprocal royalties, with each of them paying the other party low single-digit royalties, tiered based
on net sales per calendar year in its territory.
The agreement remains unrenewed as of September
30, 2024 after the expiration of its initial term. However, notwithstanding the agreement's expiration, the low single-digit royalties
and the $5,000
regulatory
milestone payable to NJCTTQ based on commercial approval
in
the Company's
territory, as described above, will continue to apply.
Through
September
30, 2024
,
no products were sold by NJCTTQ or the Company under the NJCTTQ agreement and no
regulatory milestones were achieved by the Company in the Company's territory.
ABP-100 Collaboration
and License Agreement
In
December 2019, the Company entered into an exclusive collaboration and license agreement with a related party, ABI (the "ABP-100
agreement"). Under the ABP-100 agreement, the Company granted ABI the license to develop and commercialize products and services
based on the Company's Her2-hu-OKT3 bispecific antibody ("ABP-100") within the territories of People's Republic
of China, Japan, South Korea, Southeast Asia, the Middle East and the Commonwealth of Independent States, as defined in the agreement.
Unless earlier terminated, the ABP-100 agreement, will expire upon the satisfaction of all obligations under the agreement following the
expiration of the last royalty payment obligation. Either party may terminate the agreement in the event of any uncured material breach
by the other party.
The license granted under the ABP-100 agreement was a sub-license from Memorial Sloan Kettering Cancer Center
("MSK") pursuant to MSK License Agreement (see Note 6). This agreement was terminated due to the termination of the MSK License
Agreement in September 2023.
F-
64
Under
the ABP-100 agreement, ABI agreed to use commercially reasonable efforts to reach certain development and commercial milestones for at
least one licensed product or licensed service within specified timeframes. ABI is committed to pay the Company running royalties on net
sales of any licensed products or services from the mid-single digit percentages to the low double-digit percentage, and the guaranteed
annual minimum royalties of $30 starting on the first anniversary of the effective date of the agreement (which annual minimum royalties
may be credited against the running royalties on net sales of any licensed products or services). Through the termination of this agreement
in September 2023,
no products were sold by ABI under the ABP-100 agreement.
During
the nine months ended September 30, 2024 and 2023, the Company earned $0 and $23 in minimum royalty payments, included in royalty revenue.
As of both September 30, 2024 and December 31, 2023, the accounts receivable were $53, associated with the minimum royalties
under
this agreement.
In addition to the
royalty payments, the Company could receive up to $498,000 in milestone payments per licensed product or licensed service upon the achievement
of specified research and development and sales milestone events. No milestones have been reached through the termination of this agreement
in September 2023.
The Company was also
entitled to research funding fees for costs incurred by the Company for certain sponsored research activities and the reimbursement of
60% of the costs of certain product development directed activities, as outlined in the agreement. During the nine months ended September
30, 2024 and 2023, the Company did not earn any research funding fees.
Further, the Company
was to be reimbursed for patent costs for all documented out of pocket associated with the preparation, filing, prosecution and maintenance
of patent rights in the license territory. The Company did not receive any reimbursements of patent costs during the nine months ended
September 30, 2024 and 2023.
ABP-201 Collaboration
and License Agreement
In January 2020,
the Company's consolidated subsidiary, Abmed, entered into a collaboration and license agreement with ABI (the "ABP-201 Agreement"),
pursuant to which the Company granted to ABI an exclusive, royalty-bearing, license under specified patent rights to make, use and sell
certain of its proprietary ANG-2/VEGF-HIRK bispecific antibodies within the licensed territory comprising People's Republic of China,
Japan, South Korea, Southeast Asia, the Middle East and the Commonwealth of Independent States. Unless earlier terminated in accordance
with its terms, the agreement remains in effect on a country-by-country basis until the expiration of the last royalty term in such country.
Under the ABP-201
agreement, ABI agreed to use commercially reasonable efforts to reach certain development and commercialization milestones for such bispecific
antibodies within specified territories and timeframes. ABI is committed to pay the Company up to $56,500 in milestone payments upon achieving
certain research and development events, up to $485,000 in milestone payments based on annual net sales per each licensed product, and
a double-digit percentage royalty in the low teens, tiered based on cumulative net sales by ABI, its affiliates or sublicensees beginning
with the first commercial sale of a licensed product in its territory. No
milestones have been reached
through September 30, 2024, no products were sold by ABI, and no related revenue amounts have been recorded in the accompanying consolidated
financial statements.
Celltrion Collaboration
and License Agreement
In
September 2022, the Company entered into an exclusive collaboration and license agreement with Celltrion, Inc. (the "Original Celltrion
Agreement"), a company organized and existing under the laws of South Korea ("Celltrion"). The Company and Celltrion
entered into an amendment to the agreement on August 14, 2024 in connection with the execution of the Celltrion Subscription Agreement
(the "Amended Celltrion Agreement"). The amendment is subject to termination by the Company or Celltrion if (i) the share
purchase under the Celltrion Subscription Agreement is not completed, or (ii) the Celltrion Subscription Agreement is terminated pursuant
to Section 7 of the Celltrion Subscription Agreement. Under the Amended Celltrion Agreement, the Company granted to Celltrion a worldwide
exclusive license under specified patent rights to develop, make, have made, import, export, use, have used, sell and have sold certain
of its proprietary ABP-102 bispecific antibodies.
The License Agreement also provides that
the Company is to perform certain preclinical in vitro studies. The License Agreement will remain in effect for so long as ABP-102 is
being developed or commercialized anywhere in the world. Celltrion may terminate the license agreement at any time by providing six
months prior written notice to the Company.
F-

Celltrion
is committed to pay the Company up to $10,000 under the Original Celltrion Agreement and $6,000 under the Amended Celltrion Agreement
in milestone payments upon granting the license and achieving certain research and development events, up to $1,750,000 in milestone payments
based on annual net sales per each licensed product. The proceeds from commercialization are subject to a 50/50 profit split. Amounts
that may be paid by third-party collaborators, for example upfronts, milestones and/or royalty payments from territorial commercialization
partners, are also subject to a 50/50 split. Following commercial approval of ABP-102, the Company has agreed to reimburse Celltrion 87.5%
under the Original Celltrion Agreement and 250% under the Amended Celltrion Agreement of its direct and certain indirect costs and expenses
incurred through first commercial sale. Under the Original Celltrion Agreement, Celltrion is entitled to offset amounts otherwise due
to us under the agreement until our share of these costs has been paid back; provided that the Company is entitled to a minimum 25% (or
50% under the Amended Celltrion Agreement) of profit from commercial sales and from third-party collaborators regardless of the amount
of unreimbursed development costs outstanding (and then 50% once the reimbursement has been made in full).
The
first milestone of $2,000 was achieved upon granting the license at the collaboration effective date, as defined in the Celltrion Agreement,
in December 2022 and received in January 2023. The Company allocated $64 to the initial obligation to perform in vitro testing for the
research and development services and the remaining $1,936 to the license of the Company's intellectual property, bundled with the
associated know-how.
The Company's initial obligation
to
perform in vitro testing for the research and development services
represents a distinct
performance obligation. The revenue for this performance obligation was be recognized on a straight-line based over the term of the studies.
During the nine months ended September 30, 2024 and 2023, the Company recognized $0 and $52, respectively, in connection with this performance
obligation, included in collaboration revenue. As of both September 30, 2024 and December 31, 2023, there was no deferred revenue associated
with the performance obligation.
Milestone
Payments.
The Company is entitled to development milestones under the Celltrion
Agreement and certain regulatory milestone payments which are paid upon receipt of regulatory approvals. Except for the first milestone
of $2,000 achieved in 2022, no other milestone payments were earned through September 30, 2024. The Company evaluated whether the
remaining milestones are considered probable of being reached and determined that their achievement is highly dependent on factors outside
of the Company's control. Therefore, these payments have been fully constrained and are not included in the transaction price. At
the end of each subsequent reporting period, the Company will re-evaluate the probability of achievement of each milestone and any related
constraint, and if necessary, adjust its estimate of the overall transaction price. Any such adjustments will be recorded on a cumulative
catch-up basis, which would affect the reported amount of collaboration revenues in the period of adjustment.
Profit
Splits.
As the license is deemed to be the predominant item to which profit
splits relate, the Company will recognize revenue when the related sales or third-party collaborator income occur. No profit
split revenue has been recognized from inception through September 30, 2024.

Commitments and Contingencies
Litigation
The Company, from
time to time, is subject to legal proceedings and claims that arise in the ordinary course of business. Resolution of any such matter
could have a material adverse effect on the results of operations and financial condition. The Company considers all claims on a periodic
basis and based on known facts assesses whether potential losses are considered reasonably possible, probable and estimable. Based upon
this assessment, the Company then evaluates disclosure requirements and whether to accrue for such claims in its condensed consolidated
financial statements.
The Company records
a provision for a contingent liability when it is both probable that a loss has been incurred and the amount of the loss can be reasonably
estimated.
On August 12, 2024, the Company's
landlord filed a court summons for eviction based on the Company's failure to make payments pursuant to one of its lease agreement.
According to the summons, the landlord is claiming the full amount of rental payments over the term of the lease. As of September 30,
2024, the Company owed $186 to the landlord in late rent. This amount was included in accounts payable in the condensed consolidated financial
statements as of September 30, 2024. On October 21, 2024, the Company paid the landlord $100 for late rent and maintenance expenses. A
court date was scheduled for November 14, 2024, and has been subsequently postponed to November 21, 2024. On November 20, 2024, the Company
paid the landlord $115 and on November 25, 2024, the court summons for eviction was dismissed by the landlord.
On September 12,
2023, a CRO vendor filed a lawsuit against the Company based on the Company's failure to make certain installments pursuant to a
settlement agreement entered into with this vendor on January 23, 2023. Under the settlement agreement, the Company agreed to pay a total
of $1,644 to the vendor, with $600 due 5 business days after the settlement effective date and ten monthly installments, approximately
$104 each, starting in February 2023. The Company made the upfront payment and the first four monthly installments for a total of $1,016
but failed to make the monthly installment payments due after May 2023. On January 24, 2024, the Company received the endorsement on motion
for default judgment which requested the Company to pay approximately $700 to the CRO vendor. During the nine months ended September 30,
2024, the Company accrued an additional $60 in interest, included in the interest expense. During the nine month ended September 30, 2024,
the Company made an $11 payment to CRO. As of September 30, 2024 and December 31, 2023, the outstanding balance under this settlement
agreement was $726 and $751, respectively. These amounts were included in accounts payable and accrued expenses in the condensed consolidated

lawsuit from a CRO vendor above, the Company accrued $325 and $379 as of September 30, 2024 and December 31, 2023, respectively, related
to disputed invoices with vendors.
In June 2023, the
Company received a notice of breach from MSK followed by a notice of termination in September 2023, pursuant to which MSK demanded payments
totaling $1,230 for the services performed under the MSK License Agreement (see Note 6). The corresponding liability is included in accounts
payable and accrued expenses in the consolidated financial statements as of both September 30, 2024 and December 31, 2023.
The MedImmune License
Agreement (see Note 6) provides for a research plan with target dates for an IND application (July 2021) and Phase II commencement (December
2022). These target dates were not met, which gives MedImmune (now AstraZeneca) a termination right. The Company continues to provide
annual development reports to MedImmune/AstraZeneca, most recently in January 2024. The Company does not expect a material impact on our
business if MedImmune/AstraZeneca terminates this agreement. This license was originally entered into in connection with the development
of ABP-200, which the Company is no longer developing. The Company believed that it does not need the intellectual property licensed under
that agreement for the development and eventual commercialization of ABP-201 or any of its other programs.

or otherwise of the Company with a publicly-traded special purpose acquisition company with gross proceeds of at least $30,000 from the
sale of its equity securities, or by vote of the holders of a majority of the then outstanding shares of one of the classes (Series A,
Series B, Series C, Series D, Series E or Series F Preferred Stock), voting each as a single class on an as-converted basis.
Voting

Report of Independent Registered Public Accounting
Firm
To the Stockholders and the Board of Directors of Abpro Corporation:
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Abpro
Corporation and Subsidiary (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of operations,
convertible preferred stock and stockholders' deficit and cash flows for the years then ended, and the related notes to the consolidated
financial statements (collectively, the "financial statements"). In our opinion, the financial statements present fairly,
in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and
its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.
Emphasis of a Matter Regarding Going Concern
The accompanying financial statements have been prepared assuming that
the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company has incurred net losses
since its inception, and has negative cash flows from operations and will need additional funding to complete planned development efforts.
This raises substantial doubt about the Company's ability to continue as a going concern. Management's plans in regard to
these matters also are described in Note 1. The financial statements do not include any adjustments that might result from the outcome
of this uncertainty.
Basis for Opinion
These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public
accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to
be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of
the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB.
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free
of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit
of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control
over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control
over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material
misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures
included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation
of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
/s/ Wolf & Company, P.C.
We have served as the Company's auditor since 2023.

ABPRO CORPORATION AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Amounts in thousands, except share and per
share data)
1.
Organization and Description of the Business
Nature of Operations
Abpro Corporation (the "Company") founded in 2004, was
incorporated under the laws of the State of Delaware. The Company is headquartered in Woburn, Massachusetts.
The Company is a biotechnology company dedicated to developing next-generation
antibody therapeutics to improve the lives of patients with severe and life-threatening diseases. The Company is focused on the development
of novel antibodies using its proprietary discovery and engineering platforms, primarily in the areas of immuno-oncology, ophthalmology
and infectious disease.
Risks and Uncertainties
The Company is subject to risks and uncertainties common to early-stage
companies in the biotechnology industry, including, but not limited to, development by competitors of more advanced or effective therapies,
dependence on key executives, protection of and dependence on proprietary technology, compliance with government regulations and ability
to secure additional capital to fund operations. Programs currently under development will require significant additional research and
development efforts, including preclinical and clinical testing and regulatory approval prior to commercialization. These efforts require
significant amounts of additional capital, adequate personnel and infrastructure, and extensive compliance-reporting capabilities. Even
if the Company's product development efforts are successful, it is uncertain when, if ever, the Company will realize significant
revenue from product sales.
Business Combination Agreement
On December 11, 2023, the Company entered into a business combination
agreement (the "Business Combination Agreement") with Atlantic Coastal Acquisition Corp. II, a Delaware corporation ("ACAB")
and Abpro Merger Sub Corp., a Delaware corporation ("Merger Sub"). Pursuant to the Business Combination Agreement, on the
Closing of the Business Combination, the Company will merge with and into Merger Sub, a newly formed, wholly-owned direct subsidiary of
ACAB, (the "Business Combination"), with the Company surviving the Business Combination as a wholly-owned direct subsidiary of
ACAB (the "Surviving Company"). In connection with the consummation of the Business Combination, ACAB will change its corporate
name to "Abpro Holdings, Inc."
Immediately prior to the effective time of the Business Combination,
the Company's Preferred Shares that are issued and outstanding will be converted into shares of the Company's common stock.
As a result of the Business Combination, among other things, each share of the Company's common stock, par value $0.001 per share,
will be converted into the right to receive the number of shares of newly issued ACAB Series A Common Stock (the "ACAB New Common
Shares"), par value $0.0001 per share, calculated based on the Exchange Ratio as set forth in the Business Combination Agreement.
"Exchange Ratio" is defined in the Business Combination Agreement as the Equity Value Per Share of each respective share of
the Company, divided by (b) $10.00, where "Equity Value Per Share" means (a) the Equity Value of $725,000, divided by
(b) the Fully Diluted Company Capitalization. Pursuant to the Business Combination Agreement, 22.5 million of the ACAB New Common
Shares to be issued to the Company's shareholders will be reduced from 72.5 million shares of the Merger Consideration and
equally divided among the Sponsor, the Company and Abpro Bio Co., Ltd. for each such party to use in the PIPE Financing or to obtain capital
for ACAB or the Surviving Company. Consummation of the transactions contemplated by the Business Combination Agreement are subject to
satisfaction or waiver of customary conditions of the respective parties, including receipt of required regulatory approvals, receipt
of approval from shareholders of ACAB and the Company for consummation of the Business Combination and certain other actions related thereto
by our shareholders.
F-
81
The Business Combination Agreement may be
terminated under certain circumstances prior to the Closing, including, but not limited to, (i) by mutual written consent of
ACAB and the Company, (ii) by the Company if ACAB breaches its representations, warranties or covenants such that the
conditions set forth in the Business Combination Agreement would not be satisfied, and such party fails to cure such breach (other
than for certain limited exceptions), (iii) by ACAB if the Company breaches its representations, warranties or covenants such that
the conditions set forth in the Business Combination Agreement would not be satisfied, and such party fails to cure such breach
(other than for certain limited exceptions), (iv) by either ACAB or the Company if the Business Combination is not consummated by
June 1, 2024, (v) by either ACAB or the Company if any governmental entity issues an order or taken any other action
permanently enjoining, restraining or otherwise prohibiting the Business Combination and such order or other action has become final
and non-appealable, (vi) by either ACAB or the Company if certain required approvals are not obtained from the ACAB
stockholders after the conclusion of a special meeting of ACAB's stockholders held for such purpose at which such shareholders
voted on such approvals and (vii) by ACAB, if the Company does not deliver to ACAB the required Company Stockholder Written
Consent prior to the Company Stockholder Written Consent Deadline as defined in the Business Combination Agreement.
If the Business Combination Agreement is validly terminated, none of
the parties to the Business Combination Agreement will have any liability or any further obligation under the Business Combination Agreement,
other than customary confidentiality obligations, except in the case of Willful Breach or fraud.
Going Concern
The Company is required to evaluate whether there are conditions or
events, considered in the aggregate, that raise substantial doubt abouts its ability to continue as a going concern within one year after
the date that the consolidated financial statements are available to be issued. Through December 31, 2023, the Company has funded
its operations mainly through equity and debt financing and to a lesser extent, payments received in connection with collaboration and
license agreements.
Since inception, the Company has incurred recurring losses, including
a net loss of $11,706 and $17,215 for the years ended December 31, 2023 and 2022, respectively. The Company had an accumulated deficit
of $105,571 as of December 31, 2023. The Company expects to incur operating losses for the foreseeable future. On October 18,
2023, the Company entered into a promissory note agreement with Abpro Bio International, Inc. ("ABI"), a significant investor
in the Company's Series E and F convertible preferred stock (See Note 9), to receive up to $6,000. The Company received $3,315 through
the date of issuance of these consolidated financial statements under this promissory note, including $1,442 during the year ended December 31,
2023 (see Note 9 for terms and conditions).
The future viability of the Company is largely dependent on its ability
to raise additional capital to finance its operations. The Company expects to seek additional funding through equity and debt financings,
collaboration agreements and research grants. Although the Company has been successful in raising capital in the past, there is no assurance
that it will be successful in obtaining such additional financing on terms acceptable to the Company, if at all. If the Company is unable
to obtain funding, the Company could be forced to delay, reduce or eliminate its research and development programs, product portfolio
expansion or commercialization efforts, which could adversely affect its business prospects.
Accordingly, based on the considerations discussed above, management
has concluded there is substantial doubt as to the Company's ability to continue as a going concern within one year after the date
the consolidated financial statements are issued. The Company plans to continue to fundraise, as well as seek alternate revenues from
collaboration and license agreements. If adequate funds are not available, the Company may require initiating steps to slow cash burn,
extending the cash runway until financing can be secured. The consolidated financial statements do not include any adjustments with respect
to the carrying amounts of assets and liabilities and their classification that might result from the outcome of this uncertainty.

Summary of Significant Accounting Policies
Basis of Presentation
The consolidated financial statements have been prepared in accordance
with accounting principles generally accepted in the United States of America ("U.S. GAAP") and the applicable rules and regulations
of the U.S. Securities and Exchange Commission ("SEC"). The accompanying consolidated financial statements include all of
the accounts of the Company and its subsidiary, AbMed Corporation ("AbMed"). All intercompany balances and transactions have
been eliminated in consolidation.
Use of Estimates
The preparation of consolidated financial statements in
conformity with U.S. GAAP requires management to make estimates and judgments that affect the amounts reported in the consolidated
financial statements and accompanying notes. Actual results could differ materially from those estimates. Significant estimates in
these consolidated financial statements include stock-based compensation expense, fair value of common stock, revenue allocated to
various performance obligations under license and collaboration agreements, pre-clinical and clinical accrued expenses, discount
rates in relation to lease right-of-use assets and liabilities, valuation and realizability of deferred tax assets and the ability
to continue as a going concern. On an ongoing basis, the Company evaluates its estimates, judgments, and methodologies. The Company
bases its estimates on historical experience and on various other assumptions believed to be reasonable. Due to the inherent
uncertainty involved in making estimates, actual results could differ materially from those estimates.
In March 2022, the Company received an invoice from Mabwell (Shanghai)
Bioscience Co., Ltd. ("Mabwell") for approximately $3.5 million in connection with the manufacturing of certain clinical material
for the Company. The material was received during a period of time where the Company could not verify what was received as there was no
employees at the location at the time due to COVID. Accordingly, the Company recorded the estimated amount in accounts payable, and subsequently
engaged in discussion with Mabwell about the invoiced amount and its validity. The Company continues to dispute the amount and its contractual
basis as the parties neither finalized nor executed a clinical trial manufacturing agreement.
Cash
Financial instruments that potentially subject the Company to concentrations
of credit risk consist primarily of cash. The Company maintains its cash in bank deposit accounts, which, at times, may exceed federally
insured limits. As of December 31, 2023 and 2022, the Company has not experienced a loss on its accounts for which it exceeds federally
insured deposit limits.
Restricted Cash
The restricted cash balance is related to a balance provided as a collateral
associated with the letter of credit for one of the Company's facility leases (Note 7 — Leases) and is reported as
a long-term asset in the consolidated balance sheets. The following tables reconcile cash and restricted cash to amounts shown in the
consolidated statements of cash flows:

Accounts receivable
Accounts receivable are stated at the amount management expects
to collect from outstanding balances under its license and collaboration arrangements. Prior to January 1, 2023, the Company
assessed the need for an allowance for potentially uncollectible accounts receivable considering historical write-off experience and
any specific risks identified in customer collection matters. Based on the assessment, the Company determined that no amount for
allowance for doubtful accounts was required as of December 31, 2022.
F-
83
Effective January 1, 2023, the Company adopted Accounting Standards
Codification ("ASC") Topic 326 Financial Instruments–Credit Losses ("ASC 326"), which requires measurement
and recognition of expected credit losses for financial assets. The Company records receivables net of any allowances for doubtful accounts
for current expected credit losses under its license and collaboration arrangements. An allowance for doubtful accounts is determined
based on the financial condition and creditworthiness of customers as well as the economic factors and trends expected to affect future
collections. Any allowance would reduce the accounts receivable to the amount that is expected to be collected. As of December 31,
2023, the Company determined that no amount for allowance for doubtful accounts was required.
Deferred Offering Costs
Deferred offering costs consist of legal, accounting, underwriting
fees and other costs that are directly related to the Business Combination. These costs will be accounted for as a reduction of proceeds
received upon completion of the closing of the Business Combination. As of December 31, 2023 and 2022, the Company had deferred offering
costs of $878 and $0.
Property and Equipment
Property and equipment are stated at cost, less accumulated depreciation.
Repairs and maintenance charges that do not increase the useful life of the assets are charged to operations as incurred.
Depreciation on property and equipment is calculated using the straight-line
method over the estimated useful lives as follows:
Classification
Estimated Useful Life
(in years)
Computer hardware and software
3 - 5
Lab equipment
3 - 5
Furniture and fixtures
5 - 7
Leasehold improvements
Shorter of useful life or lease term
Leases
The Company accounts for leases in accordance with ASC Topic 842,
Leases
("ASC
842"). Under ASC 842, the Company assesses its contracts at inception to determine whether the contract contains a lease,
including evaluation of whether the contract conveys the right to control an explicitly or implicitly identified asset for a period
of time. As a lessee, the Company records a right-of-use asset and a lease liability in its consolidated balance sheets for all
leases with terms longer than 12 months. Leases are classified as either finance or operating, with classification affecting the
pattern of expense recognition in the consolidated statement of operations.
The Company recognizes operating lease right-of-use
("ROU") assets and operating lease liabilities in the consolidated balance sheets. ROU assets represent the
Company's right to use an underlying asset during the lease term and lease liabilities represent the Company's
obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at commencement date based
on the net present value of fixed lease payments over the lease term. The Company's lease term includes options to extend or
terminate the lease when it is reasonably certain that it will exercise that option. ROU assets also include any advance lease
payments made and are net of any lease incentives. As most of the Company's operating leases do not provide an implicit rate,
the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present
value of lease payments. The incremental borrowing rate is the rate of interest that the Company would expect to pay to borrow over
a similar term, and on a collateralized basis, an amount equal to the lease payments in a similar economic environment.
The Company enters into lease agreements for the use of
laboratory and office space, and laboratory equipment, under both operating and finance leases. Operating leases are included in
Right-of-use asset – operating lease, and Operating lease liability – current and Operating lease liability –
noncurrent in the consolidated balance sheets. Finance leases are included in Property and Equipment, net, Finance lease liability
– current and Finance lease liability – noncurrent in the consolidated balance sheets.
F-
84
Patents
The Company incurs costs related to patent license fees and patent
applications. These payments are capitalized when the Company believes that there is a high likelihood that the patent will be issued
and there will be future economic benefit associated with the patent. These costs are amortized from the date of the patent application
on a straight-line basis over the estimated useful life of 20 years, which is the legal life of the patent. All costs associated with
abandoned patents applications are expensed.
Impairment of Long-lived Assets
The Company periodically evaluates its long-lived assets for potential
impairment. Potential impairment is assessed when there is evidence that events or changes in circumstances indicate that the carrying
amount of an asset may not be recovered. Recoverability of these assets is based on undiscounted expected future cash flows from the assets,
considering a number of factors, including past operating results, budgets and economic projections, market trends, and product development
cycles. An impairment of the carrying value of each asset is assessed when the undiscounted expected future cash flows derived from the
asset are less than its carrying value. The impairment loss would be measured as the excess of the carrying value of the impaired asset
over its fair value. No impairment charges were recorded for the years ended December 31, 2023 and 2022.
Revenue Recognition
The Company recognizes revenue in accordance with the guidance of
Revenue
From Contracts With Customers
, Accounting Standards Codification Topic 606 ("ASC 606"). Under ASC 606, the Company
recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration
that the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements
the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the
contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction
price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when
(or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is
probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the
customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the
goods or services promised within each contract and determines those that are performance obligations, and assesses whether each
promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is
allocated to the respective performance obligation when (or as) the performance obligation is satisfied.
License and collaboration revenues
The Company's license and collaboration revenues have been
generated primarily through collaborative research, development, manufacturing and commercialization agreements. The terms of these
agreements generally include the license of intellectual property and associated know-how and the provision of other  goods and
services. Payments to the Company under these arrangements typically include one or more of the following: non-refundable, up-front
license fees; milestone payments; and royalties on future product sales.
F-
85
License of Intellectual Property
. If a license to the Company's
intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company
recognizes revenue allocated to the license when the license is transferred to the customer and the customer is able to use and benefit
from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined
performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if
over time, the appropriate method of measuring progress for purposes of recognizing revenue associated with the bundled performance obligation.
Milestone Payments.
At the inception of each arrangement
that includes milestone payments based upon the achievement of specified clinical development, regulatory and/or sales milestones,
the Company evaluates whether the milestones are considered probable of being achieved and estimates the amount to be included in
the transaction price. If it is probable that a significant revenue reversal would not occur, the associated milestone amount is
included in the transaction price. Milestone payments that are dependent on factors outside of the Company's control, such as
regulatory approvals, are not considered probable of being achieved until those approvals are received. These payments are fully
constrained and therefore are not included in the transaction price. At the end of each reporting period, the Company re-evaluates
the probability of achievement of each milestone and any related constraint and, if necessary, adjusts its estimate of the overall
transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect the reported amount of
license and collaboration revenues in the period of adjustment.
Royalties.
For arrangements that include sales-based
royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which
the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the
performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).
Research and Development Expenses
The Company's research and development expenses consist primarily
of salaries, payroll taxes, employee benefits and stock-based compensation charges for those individuals involved in research and development
efforts, as well as consulting expenses, third-party research and development expenses, laboratory supplies and clinical materials. Research
and development expenses are charged to expense as incurred. Payments made prior to the receipt of goods or services to be used in research
and development are capitalized until the goods or services are received.
Income Taxes
Income taxes are accounted for under the asset and liability
method, as required by FASB ASC Topic 740,
Income Taxes
("ASC 740"). The Company provides for federal, and state
income taxes currently payable. Deferred tax assets and liabilities are recognized for the future tax consequences attributed to
temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax
bases as well as for tax loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted income
tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or
settled.
The effect of a change in income tax rates is recognized as
income or expense in the period that includes the enactment date. The Company files income tax returns in the U.S. federal
jurisdiction and various state jurisdictions.
The Company recognizes the effect of income tax positions only if
those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that
is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change
in judgment occurs. The Company recognizes interest and/or penalties related to uncertain tax positions in income tax expense. There
were no uncertain tax positions as of December 31, 2023 and 2022.
F-
86
Share-Based Compensation
The Company accounts for share-based payments in accordance with
Accounting Standard Codification Topic 718,
Compensation—Stock Compensation
("ASC 718"). Under ASC 718, the
Company measures, and records compensation expense related to share-based payment awards (to employees and non-employees) based on
the grant date fair value using the Black-Scholes option-pricing model. The Company recognizes forfeitures related to employee
share-based payments when they occur. Forfeited share-based awards are recorded as a reduction to share-based compensation
expense.
The determination of the fair value of share-based payment awards utilizing
the Black-Scholes model is affected by the stock price and a number of assumptions, including expected volatility, expected term, risk-free
interest rate and expected dividends.
In determining the exercise prices of options granted, the Company's
Board has considered the fair value of the common stock as of the measurement date. The fair value of the common stock has been determined
by the Board at each award grant date based upon a variety of factors, including the results obtained from an independent third-party
valuation, the Company's financial position and historical financial performance, the status of technological developments within
the Company's proposed products, an evaluation or benchmark of the Company's competition, the current business climate in
the marketplace, the illiquid nature of the common stock, arm's length sales of the Company's capital stock, including convertible
preferred stock, the effect of the rights and preferences of the preferred stockholders, and then prospects of a liquidity event, among
others.
The Company does not have a history of market prices of its
common stock, and as such, volatility is estimated using historical volatilities of similar public entities. The peer group was
developed based on companies in the biotechnology industry. The Company will continue to apply this process until a sufficient
amount of historical information regarding the volatility of its own stock price becomes available. The expected term of the awards
is estimated based on the simplified method for grants to employees and is based on the contractual term for non-employee awards.
The risk-free interest rate assumption is based on observed interest rates appropriate for the terms of the awards. The dividend
yield assumption is based on history and expectation of paying no dividends.
Convertible Preferred Stock
The Company accounts for its convertible preferred stock in accordance
with the guidance in ASC Topic 480, "Distinguishing Liabilities from Equity" ("ASC 480"). Preferred stock subject
to mandatory redemption (if any) is classified as a liability instrument and is measured at fair value. Conditionally redeemable common
stock (including preferred stock that features redemption rights that are either within the control of the holder or subject to redemption
upon the occurrence of uncertain events not solely within the Company's control) is classified as temporary equity (see Note 10).
Non-controlling Interest
The Company holds an 82% ownership interest in its consolidated
subsidiary, AbMed. Non-controlling interest represents the portion of net book value in AbMed that is not owned by the Company and
is reported as a component in stockholders' equity in the consolidated balance sheets. The Company bears all the operating
costs of AbMed. Upon an event of default by the Company or upon a liquidation of AbMed, the non-controlling interest holder has the
right to put its interest in AbMed to the Company. The amount to be paid under the redemption option is equal to $2.00 per share for
each preferred share of AbMed stock held by the non-controlling interest holder plus all accrued and unpaid dividends thereon. The
Company has not allocated any losses to the noncontrolling interests given that the preferred shares held by the non-controlling
interest holder have no contractual obligations to share in the losses of AbMed. There were no operating activities in AbMed for the
years ended December 31, 2023 and 2022.
F-
87
Net Loss Per Share
The Company follows the two-class method to
compute basic and diluted net loss per share attributable to common stockholders when shares meet the definition of participating
securities. The two-class method determines net loss per common share for each class of common and participating securities
according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires
income available to common stockholders for the period to be allocated between common and participating securities based upon their
respective rights to share in the earnings as if all income for the period had been distributed. During periods of loss, there is no
allocation required under the two-class method due to there being no distributed earnings for the period coupled with the fact that
the Company's Series A, Series B, Series C, Series D, Series E and Series F (see Note 10) do not contain a contractual right
to absorb losses. Thus, all undistributed losses were allocated entirely to the Company's outstanding common stock.
Basic net loss per share attributable to common stockholders is computed
by dividing net loss attributable to common stockholders by the weighted-average number of common stock outstanding during the period
without consideration of potentially dilutive common stock. Diluted net loss per share attributable to common stockholders reflects the
potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock
or resulted in the issuance of common stock that then shared in the earnings of the Company unless inclusion of such shares would be anti-dilutive.
As the Company has incurred losses for the years ended December 31, 2023 and 2022, basic and diluted net loss per share is the same
for each period.
The following table presents the potentially dilutive shares that were
excluded from the computation of diluted net loss per share of common stock attributable to common stockholders, because their effect
was anti-dilutive:

Segment Reporting
The Company conducts its business activities and reports financial
results as one operating segment and one reportable segment, which is consistent with the Company structure and the way the Company operates
its business.
Recently Adopted Accounting Pronouncements
In June 2016, the FASB issued Accounting Standards Update
No. 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments. ASU 2016-13 requires
measurement and recognition of expected credit losses for financial assets. In April 2019, the FASB issued clarification to ASU
2016-13 within ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses. ASC 326 is effective for
fiscal years beginning after December 15, 2022. The Company adopted this standard on January 1, 2023, which had no
material impact on the Company's consolidated financial statements.

License and Collaboration Agreements
NJCTTQ
Collaboration Agreement
In
January 2019, the Company entered into a collaboration agreement with Nanjing Chia Tai Tianqing Pharmaceutical Co., Ltd. ("NJCTTQ")
to research, develop and commercialize two anti-Claudin 18.2 lead antibodies (the "NJCTTQ agreement"). Under the NJCTTQ agreement,
the Company granted a non-exclusive, non-sublicensable research license and an exclusive, sublicensable license to NJCTTQ within the
People's Republic of China and Thailand (the "NJCTTQ Territory"). The initial term of this agreement was 5 years, which
could be automatically renewed for another 5 years. If no collaboration project reached the clinical stage within the first 5 years of
the NJCTTQ agreement, then this agreement would not be renewed. The agreement expired in January 2024.
The
Company is eligible to receive up to an aggregate of $405,000 of non-refundable milestone payments from NJCTTQ upon achieving certain
development, regulatory approval, and commercialization and sales milestones for each unique licensed antibody or product in NJCTTQ Territory.
The Company agreed to pay NJCTTQ up to an aggregate of $5,000 in nonrefundable amounts upon achieving of a regulatory milestone in the
Company's territory, which includes all other countries other than the NJCTTQ Territory. No milestones have been reached through
December 31, 2023, no products were sold by NJCTTQ, and no related revenue amounts have been recorded in the accompanying consolidated
financial statements. No regulatory milestones were achieved by the Company in the Company's territory through December 31,
2023.
F-
89
The
Company and NJCTTQ agreed to pay reciprocal royalties, with each of them paying the other party low single-digit royalties, tiered based
on net sales per calendar year in its territory. Through December 31, 2023, no products were sold by NJCTTQ or the Company under
the NJCTTQ agreement.
ABP-100
Collaboration and License Agreement
In
December 2019, the Company entered into an exclusive collaboration and license agreement with a related party, ABI (the
"ABP-100 agreement"). Under the ABP-100 agreement, the Company granted ABI the license to develop and commercialize
products and services based on the Company's Her2-hu-OKT3 bispecific antibody ("ABP-100") within the territories
of People's Republic of China, Japan, South Korea, Southeast Asia, the Middle East and the Commonwealth of Independent States,
as defined in the agreement. Unless earlier terminated, the ABP-100 agreement, will expire upon the satisfaction of all obligations
under the agreement following the expiration of the last royalty payment obligation. Either party may terminate the agreement in the
event of any uncured material breach by the other party. The license granted under the ABP-100 agreement was a sub-license from
Memorial Sloan Kettering Cancer Center ("MSK") pursuant to MSK License Agreement (see Note 6). This agreement was
terminated due to the termination of the MSK License Agreement in September 2023.
Under
the ABP-100 agreement, ABI agreed to use commercially reasonable efforts to reach certain development and commercial milestones for at
least one licensed product or licensed service within specified timeframes. ABI is committed to pay the Company running royalties on
net sales of any licensed products or services from the mid-single digit percentages to the low double-digit percentage, and the guaranteed
annual minimum royalties of $30 starting on the first anniversary of the effective date of the agreement (which annual minimum royalties
may be credited against the running royalties on net sales of any licensed products or services). Through the termination of this agreement
in September 2023, no products were sold by ABI under the ABP-100 agreement. During the years ended December 31, 2023 and 2022,
the Company earned $23 and $30, respectively, in minimum royalty payments, included in royalty revenue. As of December 31, 2023
and 2022, the accounts receivable were $53 and $30, respectively, associated with the minimum royalties under this agreement.
In
addition to the royalty payments, the Company may receive up to $498,000 in milestone payments per licensed product or licensed service
upon the achievement of specified research and development and sales milestone events. No milestones have been reached through the termination
of this agreement in September 2023.
The
Company is also entitled to research funding fees for costs incurred by the Company for certain sponsored research activities and the
reimbursement of 60% of the costs of certain product development directed activities, as outlined in the agreement. During the years
ended December 31, 2023 and 2022, the Company did not earn any research funding fees.
Further,
the Company is to be reimbursed for patent costs for all documented out of pocket associated with the preparation, filing, prosecution
and maintenance of patent rights in the license territory. During the years ended December 31, 2023 and 2022, the Company received $0
and $15, respectively, in reimbursements of patent costs included in collaboration revenue.
ABP-201
Collaboration and License Agreement
In
January 2020, the Company's consolidated subsidiary, Abmed, entered into a collaboration and license agreement with ABI (the "ABP-201
Agreement"), pursuant to which the Company granted to ABI an exclusive, royalty-bearing, license under specified patent rights
to make, use and sell certain of its proprietary ANG-2/VEGF-HIRK bispecific antibodies within the licensed territory comprising People's
Republic of China, Japan, South Korea, Southeast Asia, the Middle East and the Commonwealth of Independent States. Unless earlier terminated
in accordance with its terms, the agreement remains in effect on a country-by-country basis until the expiration of the last royalty
term in such country.
F-
90
Under
the ABP-201 agreement, ABI agreed to use commercially reasonable efforts to reach certain development and commercialization milestones
for such bispecific antibodies within specified territories and timeframes. ABI is committed to pay the Company up to $56,500 in milestone
payments upon achieving certain research and development events, up to $485,000 in milestone payments based on annual net sales per each
licensed product, and a double-digit percentage royalty in the low teens, tiered based on cumulative net sales by ABI, its affiliates
or sublicensees beginning with the first commercial sale of a licensed product in its territory. No milestones have been reached through
December 31, 2023, no products were sold by ABI, and no related revenue amounts have been recorded in the accompanying consolidated
financial statements.
The
Company is also to be reimbursed for patent costs for all documented out of pocket associated with the preparation, filing, prosecution
and maintenance of patent rights in the license territory. During the years ended December 31, 2023 and 2022, the Company earned
$32 and $48, respectively, in reimbursements of patent costs included in collaboration revenue. As of December 31, 2023 and 2022,
the accounts receivable were $32 and $0, respectively, associated with the patent cost reimbursement under this agreement.
Celltrion
Collaboration and License Agreement
In
September 2022, the Company entered into an exclusive collaboration and license agreement with Celltrion, Inc. (the "Celltrion
Agreement"), a company organized and existing under the laws of South Korea ("Celltrion"). Under this agreement, the
Company granted to Celltrion a worldwide exclusive license under specified patent rights to develop, make, have made, import, export,
use, have used, sell and have sold certain of its proprietary ABP-102 bispecific antibodies. The License Agreement also provides that
the Company is to perform certain preclinical in vitro studies. The License Agreement will remain in effect for so long as ABP-102 is
being developed or commercialized anywhere in the world. Celltrion may terminate the license agreement at any time by providing six
months prior written notice to the Company.
Celltrion
is committed to pay the Company up to $10,000 in milestone payments upon granting the license and achieving certain research and development
events, up to $1,750,000 in milestone payments based on annual net sales per each licensed product. The proceeds from commercialization
are subject to a 50/50 profit split. Amounts that may be paid by third-party collaborators, for example upfronts, milestones and/or royalty
payments from territorial commercialization partners, are also subject to a 50/50 split. Following commercial approval of ABP-102, the
Company has agreed to reimburse Celltrion 87.5% of its direct and certain indirect costs and expenses incurred through first commercial
sale. Celltrion is entitled to offset amounts otherwise due to us under the agreement until our share of these costs has been paid back;
provided that the Company is entitled to a minimum 25% of profit from commercial sales and from third-party collaborators regardless
of the amount of unreimbursed development costs outstanding (and then 50% once the reimbursement has been made in full).
The
first milestone of $2,000 was achieved upon granting the license at the collaboration effective date, as defined in the Celltrion Agreement,
in December 2022 and was received in January 2023. The Company allocated $64 to the initial obligation to perform in vitro testing for
the research and development services and the remaining $1,936 to the license of the Company's intellectual property, bundled with
the associated know-how, which was recognized in revenue during the year ended December 31, 2022.
The
Company's initial obligation to perform in vitro testing for the research and development services represents a distinct performance
obligation. The revenue for this performance obligation will be recognized on a straight-line based over the term of the studies. The
related deferred revenue was $0 and $64 as of December 31, 2023 and 2022, respectively. During the years ended December 31,
2023 and 2022, the Company recognized $64 and $0, respectively, in connection with this performance obligation, included in collaboration
revenue.
F-
91
The
Company is also to be reimbursed for 50% of all documented out of pocket patent costs associated with the preparation, filing, prosecution
and maintenance of patent rights in the license territory. During the years ended December 31, 2023 and 2022, the Company earned
$3 and $0, respectively, in reimbursements of patent costs included in collaboration revenue. As of December 31, 2023 and 2022,
the accounts receivable were $3 and $0, respectively, associated with the patent cost reimbursement under this agreement.
Milestone
Payments.
The Company is entitled to development milestones under the Celltrion Agreement and certain regulatory milestone payments
which are paid upon receipt of regulatory approvals. Except for the first milestone of $2,000 achieved in 2022, no other milestone
payments were earned through December 31, 2023. The Company evaluated whether the remaining milestones are considered probable of
being reached and determined that their achievement is highly dependent on factors outside of the Company's control. Therefore,
these payments have been fully constrained and are not included in the transaction price. At the end of each subsequent reporting period,
the Company will re-evaluate the probability of achievement of each milestone and any related constraint, and if necessary, adjust its
estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect the reported
amount of collaboration revenues in the period of adjustment.
Profit
Splits.
As the license is deemed to be the predominant item to which profit splits relate, the Company will recognize revenue
when the related sales or third-party collaborator income occur. No profit split revenue was recognized through December 31,
2023.

Commitments and Contingencies
Litigation
The
Company, from time to time, is subject to legal proceedings and claims that arise in the ordinary course of business. Resolution of any
such matter could have a material adverse effect on the results of operations and financial condition. The Company considers all claims
on a periodic basis and based on known facts assesses whether potential losses are considered reasonably possible, probable and estimable.
Based upon this assessment, the Company then evaluates disclosure requirements and whether to accrue for such claims in its consolidated
financial statements.
The
Company records a provision for a contingent liability when it is both probable that a loss has been incurred and the amount of the loss
can be reasonably estimated.
On
September 12, 2023, a CRO vendor filed a lawsuit against the Company based on the Company's failure to make certain installments
pursuant to a settlement agreement entered into with this vendor on January 23, 2023. Under the settlement agreement, the Company
agreed to pay a total of $1,644 to the vendor, with $600 due 5 business days after the settlement effective date and ten monthly installments,
approximately $104 of each, starting in February 2023. This settlement amount was included in the accounts payable in the consolidated
financial statements as of December 31, 2022. The Company made the upfront payment and the first four monthly installments for a
total of $1,016 but failed to make the monthly installment payments due after May 2023. On January 24, 2024, the Company received
the endorsement on motion for default judgment which requested the Company to pay approximately $700 to the CRO vendor. This amount was
included in the accounts payable in the consolidated financial statements as of December 31, 2023.
In
addition to the lawsuit from CRO vendor above, the Company accrued $379 and $348 as of December 31, 2023 and 2022, respectively,
for disputed invoices with vendors.
In
June 2023, the Company received a notice of breach from MSK followed by a notice of termination in September 2023, pursuant to which
MSK demanded payments totaling $1,230 for the services performed under the MSK License Agreement (see Note 6) and is included in accounts
payable and accrued expenses in the consolidated financial statements as of December 31, 2023.
The
MedImmune License Agreement (see Note 6) provides for a research plan with target dates for an IND application (July 2021) and Phase
II commencement (December 2022). These target dates were not met, which gives MedImmune (now AstraZeneca) a termination right. The Company
continues to provide annual development reports to MedImmune/AstraZeneca, most recently in January 2024. The Company does not expect
a material impact on our business if MedImmune/AstraZeneca terminates this agreement. This license was originally entered into in connection
with the development of ABP-200, which the Company is no longer developing. The Company believes that it is not using and does not expect
to use the intellectual property rights licensed thereunder in connection with the development and eventual commercialization of ABP-201
if such development efforts are successful.

classes (Series A, Series B, Series C, Series D, Series E or Series F Preferred Stock), voting each as a single class on an as-converted
basis.
Voting
Each
holder of Preferred Stock is entitled to the number of votes equal to the number of shares of common stock into which the Preferred Stock
could be converted as of the record date. Except as otherwise specified in the Certificate of Incorporation, the holders of Preferred
Stock and the holders of common stock vote as a single class on all matters submitted to a vote of stockholders, and not as separate
classes. Series A, Series B, Series C, and Series D stockholders are collectively entitled to one elect one director. In addition, four
directors may be elected by the majority of the common stock held by the founders of the Company.
Redemption
Rights
At
any time after January 1, 2019, and at the election of the holders of at least a majority of the then outstanding shares of Series
A, the Company shall redeem all of Series A elected by the outstanding shares of Series A that have not been previously converted into
common stock. The Company is to redeem the shares of Series A by paying in cash an amount per share equal to the original issue price
for such Series A of $93.23 per share, plus all declared and unpaid dividends in three equal annual installments.
The
Convertible Preferred Stock is redeemable upon a change in control. The occurrence of a change in control shall be deemed a Liquidation
Event and the holders of shares of Convertible Preferred Stock then outstanding will be entitled to the same rights outlined in the Liquidation
Preference section below. The deemed Liquidation Event was defined as (i) the acquisition of the Company by another entity by means
of any transaction or series of related transactions to which the Company is party (including, without limitation, any stock acquisition,
reorganization, merger or consolidation but excluding any bona fide sale of stock solely for capital raising purposes) other than a transaction
or series of transactions in which the holders of the voting securities of the Company outstanding immediately prior to such transaction
continue to retain, immediately after such transaction or series of transactions, as a result of shares in the Company held by such holders
prior to such transaction, at least a majority of the total voting power represented by the outstanding voting securities of the Company
or such surviving entity; or (ii) a sale, lease, transfer, exchange, exclusive license or other description of all or substantially
all of the assets of the Company and its subsidiaries taken as a whole by means of any transaction or series of related transactions.
As such, the Convertible Preferred Stock is classified as temporary equity in the consolidated financial statements.
Liquidation
Preference
In
the event of any liquidation, dissolution or winding up of the Company, either voluntary or involuntary, the holders of the Series F,
Series E and Series D are entitled to receive, prior and in preference to any distribution to the holders of the common stock or any
other series of Preferred Stock, an amount per share for each share of Series F, Series E and Series D held by them equal to the sum
of original issue price, and all declared but unpaid dividends (if any). After the payment or setting aside for payments to the Series
F, Series E and Series D, the event of any liquidation, dissolution or winding up of the Company or other liquidation event, either voluntary
and involuntary, the holders of the Series C are entitled to receive, prior and in preference to any distribution to the holders of the
common stock, Series A, or Series B, an amount per share for each share of Series C held by them equal to the sum of original issue price
and all declared but unpaid dividends (if any).

After
the payment or setting aside for payment to the holders of Series F, Series E and Series D, and Series C, in the event of any liquidation,
dissolution or winding up of the Company or other liquidation event, either voluntary or involuntary, the holders of the Series A and
Series B are entitled to receive, prior and in preference to any distribution to the holders of the common stock, an amount per share
for each share of Series A or Series B, held by them equal to the sum of original issue price and all declared but unpaid dividends (if
any).
After
the payment or setting aside for payment to the holders of the Preferred Stock, in the event of any liquidation, dissolution or winding
up of the Company or other liquidation event, either voluntary and involuntary, the holders of the common stock are entitled to receive
remaining assets of the Company legally available for distribution on a pro rata basis.

The
Company regularly assesses the need for a valuation allowance against its deferred tax assets. In making that assessment, the Company
considers both positive and negative evidence related to the likelihood of realization of the deferred tax assets to determine, based
on the weight of available evidence, whether it is more-likely-than-not that some or all of the deferred tax assets will not be realized.
In assessing the realizability of deferred tax assets, the Company considers taxable income in prior carryback years, as permitted under
the tax law, forecasted taxable earnings, tax planning strategies, and the expected timing of the reversal of temporary differences.
This determination requires significant judgment, including assumptions about future taxable income that are based on historical and
projected information and is performed on a jurisdiction-by-jurisdiction basis.
The
Company continues to maintain a valuation allowance against its deferred tax assets. During the years ended December 31, 2023 and
2022, management assessed the positive and negative evidence in its operations, and concluded that it is more likely than not that its
deferred tax assets as of December 31, 2023 and 2022 will not be realized given the Company's history of operating losses.
The valuation allowance against deferred tax assets increased by approximately $3,540 and $4,965 during 2023 and 2022, respectively.

On
December 22, 2017, the Tax Cuts and Jobs Act (the "Act") was enacted. Under the Act, research and development expenditures
incurred for tax years beginning after December 31, 2021 must be capitalized and amortized ratably over five or fifteen years for
tax purposes, depending on if the research activities are conducted in the U.S. or outside the U.S., respectively. Effective January 1,
2022, the Company has complied with the mandatory capitalization and amortization of research and experimentation expenditures. For the
year ended December 31, 2023, the Company capitalized $4,416 and received $1,850 of amortization deductions related to such Section 174
expenditures, which on a tax effected basis represent $3,183 of the deferred tax assets shown in capitalized research expenses in the
components of deferred tax assets and liabilities table above. For the year ended December 31, 2022, the Company capitalized $9,790
and received $704 of amortization deductions related to such Section 174 expenditures, which on a tax effected basis represent $2,482
of the deferred tax assets shown in capitalized research and development costs in the components of deferred tax assets and liabilities
table above.
As
of December 31, 2023, the Company had federal net operating losses of $74,871, which may be available to offset future federal income
tax liabilities. As a result of the Act, for U.S. federal income tax purposes, net operating losses generated after December 31,
2017 can be carried forward indefinitely, but are limited to 80% utilization against future taxable income each year. The Company's
federal net operating losses incurred prior to 2018, $22,999, expire through 2037, while its federal net operating losses incurred in
2018 and onwards, $51,872, can be carried forward indefinitely.
As of December 31, 2022, the Company had federal net operating losses
of $66,409, which may be available to offset future federal income tax liabilities.
As
of December 31, 2023 and 2022, the Company had post-apportioned Massachusetts net operating losses of $71,356 and $63,042, respectively,
that can generally be carried forward 20 years and will expire at various dates through 2043.
As of December 31, 2023, the Company
had $1,483 and $708 of federal and state research and development credits, respectively, which will expire at various dates through 2043.
As of December 31, 2022, the Company had $1,185 and $571 of federal and state research and development credits, respectively, which
will expire at various dates through 2042.
Pursuant to Internal Revenue Code Sections 382 and 383, annual use of the Company's
net operating losses and other carryforward tax attributes may be limited in the event a cumulative change in ownership of more than
50% that occurs within a three-year period. The Company has not completed an ownership change analysis pursuant to IRS Section 382.
If ownership changes have occurred or occur in the future, the amount of remaining tax attribute carryforwards available to offset taxable
income and income tax expense in future years may be restricted or eliminated. If eliminated, the related asset would be removed from
deferred tax assets with a corresponding reduction in the valuation allowance.
The
calculation of the Company's tax liabilities involves dealing with uncertainties in the application of complex tax regulations
in a multitude of jurisdictions. The Company recognizes liabilities for uncertain tax positions based on a two-step process. First, management
determines whether it is more likely than not that the tax positions will be sustained on audit, including resolution of related appeals
or litigation processes, based on their technical merits. Second, management measures the tax benefit of those positions as the largest
amount that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. While the Company believes
that it has appropriate support for the positions taken on its tax returns, the Company regularly assesses the potential outcome of examinations
by tax authorities in determining the adequacy of its provision for income taxes. As of December 31, 2023 and 2022, the Company
did not have any uncertain tax positions.
The
Company's policy is to recognize interest and penalties related to unrecognized tax benefits on the income tax expense line in
the accompanying consolidated statement of operations and any accrued interest and penalties on the related tax liability line in the
consolidated balance sheets. As of December 31, 2023 and 2022, no accrued interest or penalties are included on the related tax
liability line in the consolidated balance sheets.
The
Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions. There are currently no pending income
tax examinations. To the extent the Company has tax attribute carryforwards, the tax years in which the attribute was generated may still
be adjusted upon examination by the Internal Revenue Service and state tax authorities to the extent the tax attributes are utilized
in a future period.

Item 14. Indemnification of Directors and Officers
Indemnification of Directors and Officers
Section 145 of the DGCL provides,
generally, that a corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to
any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent
of the corporation against all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person
in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed
to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable
cause to believe his or her conduct was unlawful. A corporation may similarly indemnify such person for expenses actually and reasonably
incurred by such person in connection with the defense or settlement of any action or suit by or in the right of the corporation, provided
that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the
corporation, and, in the case of claims, issues and matters as to which such person shall have been adjudged liable to the corporation,
provided that a court shall have determined, upon application, that, despite the adjudication of liability but in view of all of the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.
In accordance with Section
102(b)(7) of the DGCL, the Charter provides that a director will not be personally liable to New Abpro or New Abpro's stockholders
for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty
of loyalty to New Abpro or New Abpro's stockholders, (ii) for acts of bad faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal
benefit. No such provision shall eliminate or limit the liability of a director for any act or omission occurring prior to the date when
such provision became effective. Accordingly, these provisions will have no effect on the availability of equitable remedies such as an
injunction or rescission based on a director's breach of his or her duty of care.
The Charter provides that
New Abpro will indemnify its present and former directors and officers to the fullest extent permitted by the DGCL and that such indemnification
will not be exclusive of any other rights to which those seeking indemnification may have or hereafter acquire under law, the ACAB charter,
the Bylaws, an agreement, a vote of stockholders or disinterested directors, or otherwise.
New Abpro has entered into
indemnification agreements with each of its current directors and executive officers. These agreements require New Abpro to indemnify
these individuals to the fullest extent permitted under Delaware law against liabilities that may arise by reason of their service to
New Abpro, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified. New Abpro
also intends to enter into indemnification agreements with future directors and executive officers.

On November 14, 2024, pursuant to the SEPA, New Abpro entered into
a Convertible Promissory Note ("Yorkville Note") for $3,000,000, and received net proceeds of $2,755,000. The Yorkville Note
has a maturity of November 13, 2025, incurs interest at a rate of 0% (or 18% upon the occurrence of an uncured Event of Default), and
is redeemable at the option of New Abpro if the VWAP of the Common Stock is less than $11.50. New Abpro has a right to convert any portion
of the Yorkville Note at any time at a conversion price equal to the lower of $11.50, 94% of the daily VWAP during the previous 5 consecutive
trading days, which may be adjusted downward upon payment of stock dividend, stock split or reclassification, or if New Abpro issues Common
Stock for no consideration or at a price lower than the then-effective Fixed Price (as defined in the Yorkville Note).
Upon the Closing of the Business Combination, the Company has the right,
but not the obligation, to issue shares of its Common Stock pursuant to the SEPA to Yorkville ("Advance Shares", and such
issuance and sale, an "Advance") and Yorkville shall subscribe for and purchase from the Company such Advance Shares, through
written notice by the Company to Yorkville ("Advance Notice"), provided (i) no balance is outstanding under a Promissory Note,
or (ii) if there is a balance outstanding under a Promissory Note, an Amortization Event (as defined in the Promissory Note), has occurred
in accordance with and subject to the terms of the Promissory Note. The Company has the discretion to select the number of Advance Shares,
not to exceed the Maximum Advance Amount (as defined in the SEPA), that it desires to issue and sell to Yorkville in each Advance Notice.
If any amount remains outstanding under any Promissory Note, without the prior written consent of Yorkville, the Company may only (other
than with respect to a deemed Advance Notice pursuant to an Investor Notice (described in the SEPA)) submit an Advance Notice (A) if an
Amortization Event has occurred and the obligation of the Company to make monthly prepayments under the Promissory Note has not ceased,
and (B) Yorkville pays the aggregate purchase price owed to the Company from such Advance by offsetting the amount of the Advance Proceeds
against an equal amount outstanding under the subject Promissory Note, subject to the terms and conditions of the SEPA.
"Maximum Advance Amount" means (A) in respect of each Advance
Notice delivered by the Company under the applicable provisions of the SEPA, an amount equal to one hundred percent (100%) of the average
of the daily traded amount of its shares of common stock during the five consecutive trading days immediately preceding an Advance Notice,
and (B) in respect of each Advance Notice deemed delivered by the Company pursuant to an Investor Notice, the amount selected by Yorkville
in such Investor Notice, which amount shall not exceed the limitations set forth in Section 3.02 of the SEPA, including, among other things,
(i) that all shares of the Company's Common Stock then beneficially owned by Yorkville and its affiliates shall not exceed 4.99%
of the then outstanding voting power of the Company or number of shares of the Company's Common Stock, (ii) that the aggregate number
of shares issued and sold to Yorkville by the Company pursuant to Advance Notices under the SEPA shall not exceed the amount registered
in respect of the transaction contemplated by the SEPA under the Registration Statement (as defined below) then in effect and (iii) that
the aggregate number of shares of Common Stock issued pursuant to the SEPA and the Pre-Paid Advance cannot exceed 19.9% of the Common
Stock of the Company outstanding as of the effective date of the SEPA (the "Exchange Cap"). The Exchange Cap shall not be
applicable if: (a) the Company's stockholders have approved the issuance of Common Stock in excess of the Exchange Cap in accordance
with the applicable rules of Nasdaq Stock Market LLC ("Nasdaq") or (b) the average price of all sales of Common Stock under
the SEPA equals or exceed the lower of (i) the Nasdaq official closing price immediately preceding the effective date of the SEPA; or
(ii) the average Nasdaq official closing price for the five trading days immediately preceding the effective date. The SEPA contemplates
purchase by Yorkville of up to $50 million in aggregate gross purchase price for newly issued shares of the Company Common Stock.
The purchase price for the
Advance Shares shall be the price per Advance Share obtained by multiplying the Market Price (i) by 96% in respect of an Advance Notice
delivered by the Company with an Option 1 Pricing Period (defined by reference to VWAP on the trading day the Advance Notice is submitted,
starting at 9:00 a.m. New York City time or, if submitted after 9:00 a.m. New York City time, at the time the investor confirms receipt),
(ii) 97% in respect of an Advance Notice with an Option 2 Pricing Period (defined by reference to the lowest daily VWAP on three consecutive
trading days commencing on the Advance Notice Date), or (iii) in the case of any Advance Notice delivered pursuant to an Investor Notice,
equal to the Conversion Price (as defined in the Promissory Note).
In the SEPA, Yorkville represented
to the Company, among other things, that it is an "accredited investor" (as such term is defined in Rule 501(a) of Regulation
D under the Securities Act). The securities issuable in connection with the SEPA are being issued and sold by the Company to Yorkville
in reliance upon the exemption from the registration requirements of the Securities Act afforded by Section 4(a)(2) of the Securities
Act.

Certain
information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not

Undertakings
(a)
The undersigned registrant hereby undertakes:
(1) To file, during any period in which
offers or sales are being made, a post-effective amendment to this registration statement:
(i) To include any prospectus required
by Section 10(a)(3) of the Securities Act of 1933;
(ii) To reflect in the prospectus
any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof)
which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding
the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed
that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the
form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent
no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement.
(iii) To include any material information
with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information
in the registration statement.
Provided, however,
that: provided, however,
that: Paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section
13 or Section 15(d) of the Securities and Exchange Act of 1934, as amended (the "Exchange Act"), that are incorporated by
reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration
statement.
(2) That, for the purpose of determining
any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide
offering thereof.
(3) To remove from registration
by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(4) That, for the purpose of determining
liability under the Securities Act to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration
statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance
on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness.
Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made
in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration
statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was
made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately
prior to such date of first use.
(5) That, for the purpose of determining
liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:
The undersigned registrant undertakes
that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting
method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following
communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to
such purchaser:
(i) Any preliminary prospectus or
prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
(ii) Any free writing prospectus
relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
(iii) The portion of any other free
writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided
by or on behalf of the undersigned registrant; and
(iv) Any other communication that
is an offer in the offering made by the undersigned registrant to the purchaser.
Insofar as indemnification
for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant
to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director,
officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification
by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
