  duty of loyalty to the corporation or its stockholders, (ii)&nbsp;for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii)&nbsp;pursuant to Section&nbsp;174 of the DGCL (providing for
  liability of directors for unlawful payment of dividends or unlawful stock purchases or redemptions), or (iv)&nbsp;for any transaction from which the director derived an improper personal benefit. The Registrant&#146;s amended and restated

  whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was a director, officer, employee or agent of such corporation, or is or was serving
  at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorney&#146;s fees), judgments, fines and amounts paid in settlement actually and
  reasonably incurred by such person in connection with such action, suit or proceeding, provided such director, officer, employee or agent acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the
  corporation&#146;s best interests and, with respect to any criminal actions or proceedings, had no reasonable cause to believe that his or her conduct was unlawful. A Delaware corporation may indemnify directors and/or officers in an action or suit
  by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the director or officer is adjudged to be liable to the corporation. Where a director or officer is successful
  on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him or her against the expenses which such director or officer actually and reasonably incurred. </P>

  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 of 1933 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 of 1933 and will be governed by the final
  adjudication of such issue. </P>

  INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

  Lumentum Holdings Inc. (the "
  Registrant
  ") hereby incorporates by reference into this Registration Statement the
  following documents previously filed with the Commission:
  (1) The Registrant's Annual Report on
  Form
  10-K
  for the fiscal year ended June 29, 2024, filed with the Commission on August 21, 2024 (the "
  Annual Report
  ");
  (2) All other reports of the Registrant filed pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the
  "
  Exchange Act
  ") since the end of the fiscal year covered by the Annual Report (other than the portions of these documents not deemed to be filed); and
  (3) The Registrant's Registration Statement on Form 10, initially filed with the Commission on February 26, 2015, as amended,
  including the description of Registrant's common stock contained therein, and any amendment or report filed for the for the purpose of updating such description.
  All documents filed by the Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act on or after the date of this
  Registration Statement and prior to the filing of a post-effective amendment to this Registration Statement that indicates that all securities offered have been sold or that deregisters all securities then remaining unsold shall be deemed to be
  incorporated by reference in this Registration Statement and to be part hereof from the date of filing of such documents;
  provided
  ,
  however
  , that documents or information deemed to have been furnished and not filed in accordance with
  the rules of the Commission shall not be deemed incorporated by reference into this Registration Statement.
  Any statement contained in a
  document incorporated or deemed to be incorporated by reference herein shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein or in any subsequently filed document
  which also is or is deemed to be incorporated by reference herein modifies or supersedes such statement. Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration
  Statement.
  Item 4. Description of Securities.
  Not applicable.
  Item 5. Interests of
  Named Experts and Counsel.
  Not applicable.
  Item 6. Indemnification of Directors and Officers.
  Reference is made to Section 102(b)(7) of the Delaware General Corporation Law (the "
  DGCL
  "), which permits a
  corporation in its certificate of incorporation or an amendment thereto to eliminate or limit the personal liability of a director for violations of the director's fiduciary duty, except (i) for any breach of the director's fiduciary
  duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the DGCL (providing for
  liability of directors for unlawful payment of dividends or unlawful stock purchases or redemptions), or (iv) for any transaction from which the director derived an improper personal benefit. The Registrant's amended and restated
  certificate of incorporation contains the provisions permitted by Section 102(b)(7) of the DGCL.
  Reference is made to
  Section 145 of the DGCL, which provides that a corporation may indemnify any persons, including directors and officers, who are, or are threatened to be made, parties to any threatened, pending or completed legal action, suit or proceeding,
  whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was a director, officer, employee or agent of such corporation, or is or was serving
  at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorney's fees), judgments, fines and amounts paid in settlement actually and
  reasonably incurred by such person in connection with such action, suit or proceeding, provided such director, officer, employee or agent acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the
  corporation's best interests and, with respect to any criminal actions or proceedings, had no reasonable cause to believe that his or her conduct was unlawful. A Delaware corporation may indemnify directors and/or officers in an action or suit
  by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the director or officer is adjudged to be liable to the corporation. Where a director or officer is successful
  on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him or her against the expenses which such director or officer actually and reasonably incurred.
  The Registrant's bylaws provide indemnification of directors and officers to the
  fullest extent permitted by applicable law. The Registrant has obtained liability insurance for each director and officer for certain losses arising from claims or charges made against them while acting in their capacities as the Registrant's
  directors or officers. The Registrant has entered into indemnification agreements with each of its executive officers and directors. These agreements provide that, subject to limited exceptions and among other things, the Registrant will indemnify
  each of its executive officers and directors to the fullest extent permitted by law and advance expenses to each indemnitee in connection with any proceeding in which a right to indemnification is available.

  Item 9. 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 a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table, as
  applicable, in the effective registration statement; and
  (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 paragraphs (A)(1)(i) and (A)(1)(ii) 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 Exchange Act of 1934 that are incorporated by reference in this 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.
  B. The undersigned Registrant
  hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and,
  where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement 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.
  C. Insofar as indemnification for liabilities arising under the Securities Act of 1933 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 of 1933 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 of 1933 and will be governed by the final
  adjudication of such issue.
  S
  IGNATURES
  Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe

  State of California, on the 14
