EXPLANATORY NOTE

This Amendment to Form 10-K (the “Amendment”) amends the Annual Report on Form 10-K of Allegiant Travel Company for the fiscal year ended December 31, 2023, originally filed with the Securities and Exchange Commission (“SEC”) on February 29, 2024 (the “Original Filing”). We are filing this Amendment to correct the inadvertent omission of a statement in Item 9B, paragraph (b) and the inadvertent omission of Exhibit 97.1 from Item 15 in the Original Filing. In connection with the filing of this Amendment and pursuant to the rules of the SEC, we are including with this Amendment certain new certifications by our principal executive officer and principal financial officer. Accordingly, Item 15 of Part IV has also been amended to reflect the filing of these new certifications.

Except as described above, no other changes have been made to the Original Filing. The Original Filing continues to speak as of the date of the Original Filing, and we have not updated the disclosures contained therein to reflect any events which occurred at a date subsequent to the filing of the Original Filing other than as expressly indicated in this Amendment. In this Amendment, unless the context indicates otherwise, the terms “Company,” “we,” “us,” and “our” refer to Allegiant Travel Company. Other defined terms used in this Amendment but not defined herein shall have the meaning specified for such terms in the Original Filing.

EX-97.1

Exhibit 97.1

Allegiant Travel Company

Policy Relating to

Recovery of Erroneously Awarded Compensation

This Policy has been adopted by the Board of Directors of Allegiant Travel Company (the “Company”) effective as of December 1, 2023. With respect to compensation paid to executive officers after October 2, 2023, this Policy shall supersede the Company’s Executive Compensation Recoupment Policy adopted by the Board on April 26, 2016 (the “Prior Policy”). The Prior Policy shall remain in effect for compensation paid to executive officers prior to October 2, 2023.

(1) The Company will recover reasonably promptly the amount of “erroneously awarded incentive-based compensation” (as defined below) in the event that the Company is required to prepare an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period.

(2) The Company’s recovery policy applies to all incentive-based compensation received by a person: 

(A) After beginning service as an executive officer; 

(B) Who served as an executive officer at any time during the performance period for that incentive-based compensation; and

(C) During the three completed fiscal years immediately preceding the date that the Company is required to prepare an accounting restatement as described in paragraph (1) of this Policy. The Company’s obligation to recover erroneously awarded compensation is not dependent on if or when the restated financial statements are filed.

(3) For purposes of determining the relevant recovery period, the date that the Company is required to prepare an accounting restatement as described in paragraph (1) of this Policy is the earlier to occur of:

(A) The date the Company’s Board of Directors, a committee of the Board of Directors, or the officer or officers of the Company authorized to take such action if Board action is not required, concludes, or reasonably should have concluded, that the Company is required to prepare an accounting restatement as described in paragraph (1) of this Policy; or

(B) The date a court, regulator, or other legally authorized body directs the Company to prepare an accounting restatement as described in paragraph (1) of this Policy.

(4) The amount of incentive-based compensation that is subject to the Company’s recovery policy (“erroneously awarded compensation”) is the amount of incentive-based compensation received that exceeds the amount of incentive-based compensation that otherwise would have been received had it been determined based on the restated amounts, and must be computed without regard to any taxes paid. For incentive-based compensation based on stock price or total shareholder return, where the amount of erroneously awarded compensation is not subject to mathematical recalculation directly from the information in an accounting restatement:

(A) The amount shall be based on a reasonable estimate of the effect of the accounting restatement on the stock price or total shareholder return upon which the incentive-based compensation was received; and

(B) The Company shall maintain documentation of the determination of that reasonable estimate and provide such documentation to the Nasdaq Stock Exchange (“Nasdaq”).

(5) The Company shall recover erroneously awarded compensation in compliance with this recovery policy except to the extent that the conditions of paragraphs (A), (B) or (C) below are met, and the Company’s Compensation Committee, or in the absence of such a committee, a majority of the independent directors serving on the Board, has made a determination that recovery would be impracticable.

(A) The direct expense paid to a third party to assist in enforcing the Policy would exceed the amount to be recovered. Before concluding that it would be impracticable to recover any amount of erroneously awarded compensation based on expense of enforcement, the Company

must make a reasonable attempt to recover such erroneously awarded compensation, document such reasonable attempt(s) to recover and provide that documentation to Nasdaq.

(B) Recovery would violate home country law where that law was adopted prior to November 28, 2022. Before concluding that it would be impracticable to recover any amount of erroneously awarded compensation based on violation of home country law, the Company must obtain an opinion of home country counsel, acceptable to Nasdaq, that recovery would result in such a violation, and must provide such opinion to Nasdaq.

(C) Recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and regulations thereunder.

(6) The Company shall be prohibited from indemnifying any executive officer or former executive officer against the loss of erroneously awarded compensation.

(7) Unless the context otherwise requires, the following definitions apply for purposes of this Policy:

Executive Officer. An executive officer is the Company’s chief executive officer, president, principal financial officer, principal accounting officer (or if there is no such accounting officer, the controller), any vice-president of the Company in charge of a principal business unit, division, or function (such as sales, administration, or finance), any other officer who performs a policy-making function, or any other person who performs similar policy-making functions for the Company. Policy-making function is not intended to include policy-making functions that are not significant. Identification of an executive officer for purposes of this Policy would include at a minimum executive officers identified in the Company’s proxy statement.

Financial Reporting Measures. Financial reporting measures are measures that are determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, and any measures that are derived wholly or in part from such measures. Stock price and total shareholder return are also financial reporting measures. A financial reporting measure need not be presented within the financial statements or included in a filing with the Commission.

Incentive-Based Compensation. Incentive-based compensation is any compensation that is granted, earned, or vested based wholly or in part upon the attainment of a financial reporting measure.

Received. Incentive-based compensation is deemed received in the Company’s fiscal period during which the financial reporting measure specified in the incentive-based compensation award is attained, even if the payment or grant of the incentive-based compensation occurs after the end of that period.

(8)This Policy is effective as of December 1, 2023. The Company shall comply with this Policy for all incentive-based compensation received (as such term is defined above) by executive officers on or after October 2, 2023. The Company shall provide the disclosures required by the applicable Nasdaq rules and in the applicable filings with the Securities and Exchange Commission on or after October 2, 2023. Notwithstanding the foregoing, the Company is only required to apply the recovery policy to incentive-based compensation received on or after October 2, 2023.
