(1)  Pursuant to Rule 416 under the Securities Act of 1933, as amended (the "Securities Act"), this Registration Statement registers an indeterminable number of additional shares of common stock which may become issuable under the Plan as a result of any future anti-dilution adjustment in accordance with the terms of the Plan or upon a stock split, stock dividend or similar transaction.
(2)  As described in the Explanatory Note on page 2 of this Registration Statement,  the number of shares of Common Stock being registered represent the 2,550,298 additional shares of AAON, Inc., a Nevada corporation (the "Company") common stock, $0.004 par value per share ("Common Stock"), approved by the Company's stockholders on May 15, 2018 for issuance under the AAON, Inc. 2016 Long-Term Incentive Plan, as amended.
(3)  Estimated solely for the purpose of calculating the amount of registration fee, in accordance with Securities Act Rule 457(c) and (h), based on the average of the high and low price per share of Common Stock on July 31, 2018, as reported on the NASDAQ Stock Market LLC.
Explanatory Note
This Registration Statement on Form S-8 is filed by AAON, Inc., a Nevada corporation (the "Company" or the "Registrant"), relating to 2,550,298 additional shares of the Company's common stock, par value $0.004 per share (the "Common Stock"), authorized for issuance under the AAON, Inc. 2016 Long-Term Incentive Plan, as amended (the "Plan"), which shares of Common Stock are in addition to the 3,839,702 shares of Common Stock registered on the Company's Registration Statement on Form S-8 filed with the Securities and Exchange Commission (the "Commission") on August 3, 2016 (Commission File No. 333-212863) (the "Prior Registration Statement").
On April 3, 2018, the Company filed with the Commission a definitive proxy statement that included proposals to, among other things, increase the number of shares available for issuance under the Plan by 2,550,298 shares of Common Stock. The proposal to increase the number of shares available for issuance under the Plan was approved by the Company's stockholders on May 15, 2018.
This Registration Statement relates to securities of the same class as that to which the Prior Registration Statement relates and is submitted in accordance with General Instruction E to Form S-8 regarding Registration of Additional Securities. Pursuant to General Instruction E to Form S-8, the contents of the Prior Registration Statement are incorporated herein by reference and made part of this Registration Statement, except as amended hereby.

This Registration Statement incorporates herein by reference the following documents which have been filed with the Commission by the Registrant:
(a)
The Company's Annual Report on Form 10-K, for the year ended December 31, 2017, filed with the Commission on February 27, 2018 (Commission File No. 000-18953);

(c)
The description of the Company's common stock which is contained under the caption "Description of Securities", in the Company's Registration Statement on Form S-1 as filed with the Commission on May 29, 1990, as such description was amended by Exhibit 1 to the Company's Current Report on Form 8-K filed with the Commission on March 24, 1994, and any other amendment or report filed with the Commission 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 after the initial filing of this Registration Statement and prior to the filing of a post-effective amendment to this Registration Statement which indicates that all securities offered have been sold or which de-registers all securities remaining unsold, shall be deemed to be incorporated by reference into this Registration Statement and to be a part hereof from the date of filing of such documents. Any statement contained herein or 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 document which is or is deemed to be incorporated by reference herein modifies or supersedes such statement.

Item 8.  Exhibits.
See the attached Exhibit Index on the page immediately following the signature pages hereto, which is incorporated herein by reference.

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;
(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 this 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 this registration statement or any material change to such information in this registration statement;
provided, however,
that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this registration statement.
(2)    That, for the purpose of determining any liability under the Securities Act, 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, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (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 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 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.
