- 5 - M. Clawback Agreement. In accordance with the Company’s clawback policy, Executive hereby agrees to reimburse the Company for all or any portion of any bonuses or incentive or equity-based compensation if the Compensation Committee in good faith determines: (a) the payment or grant was based on the achievement of certain financial results that were subsequently the subject of a material financial restatement (other than as a result of a change in accounting principles) and a lower payment or award would have occurred based upon the restated financial results; or (b) the Executive engaged in fraud or intentional misconduct related to the Company or its business. In each such instance, the Company will, to the extent practicable and allowable under applicable law, require reimbursement of any bonus or incentive or equity based compensation awarded or effect the cancellation of any unvested or deferred stock awards previously granted to the Executive in the amount by which the Executive’s bonus or incentive or equity based compensation for the relevant period exceeded the lower payment that would have been made based on the restated financial results, or such other amount as determined by the Compensation Committee, provided that the Company will not be entitled to recover bonuses or incentive or equity based compensation paid more than three years prior to the date the applicable restatement is disclosed. N. PSPs Limitations on Compensation. Notwithstanding anything herein to the contrary, in no event shall any cash or stock-based compensation under this Agreement (whether upon payment, grant, vesting or accelerated vesting) exceed the limitations imposed upon the Company by virtue of accepting support from the U.S. Treasury under the PSPs so long as those restrictions remain in effect. In the event of any such restriction, the parties agree to use good faith to negotiate an arrangement to provide the same value of compensation to Executive at a later time or on other terms but in compliance with the PSPs.

Notwithstanding anything herein to the contrary, the acceleration of vesting of Restricted Stock, continued payment of salary after termination and other post-termination benefits shall be available to Executive under Items 6A, 6C and 6D in each case, if and only if Executive has executed and delivered to the Company a release in the form attached hereto as Exhibit A or in such other form agreed to by the parties and only so long as Executive has not revoked such general release. 5. Term. The initial term of this Agreement shall commence as of the date hereof (the “Effective Date”) and shall continue until December 31, 2026. The term of the Agreement shall expire on such date absent a renewal signed by both parties. 6. Termination: A.

In the event of Executive’s termination of employment as a result of death or such a disability: (i) Executive shall continue to receive his full base salary and related fringe benefits for a period of one (1) year after the date of termination as a result of death or disability (and even if such one-year period might extend beyond the remaining term of this Agreement); and (ii) the vesting of all outstanding stock

- 6 - options, restricted stock grants and stock appreciation rights held by Executive at the time shall be accelerated but only to the extent granted prior to the date of death or disability. B.

At the option of the Company, Executive shall immediately cease performing his duties hereunder upon receipt of the notice. If terminated without Cause pursuant to this paragraph C: (i) Executive shall continue to receive his full base salary and fringe benefits for the remaining term of this Agreement (but in no event for less than six (6) months following Executive’s termination and in no event for a shorter period than the number of months of severance pay Executive has accrued under the Company’s severance pay policy); and (ii) the vesting of all outstanding stock options, restricted stock grants and stock appreciation rights held by Executive at the time shall be accelerated but only to the extent granted prior to the date of termination and only to the extent such shares would have vested within one (1) year after the date of termination. D. Executive may terminate this Agreement immediately for “Good Reason”. For purposes of this Agreement, Good Reason shall be defined as (i) failure of the Company to make any payment or provide any benefit to Executive hereunder, which failure is not cured within thirty (30) days after the Company’s receipt of written notice of such default, or (ii) a material diminution of Executive’s duties and responsibilities or his title without Executive’s consent, or (iii) the principal location at which Executive is to perform his duties is relocated to a place more than fifty (50) miles from Las Vegas, Nevada (provided Executive is required to live in the Las Vegas area).

In the event of a termination for Cause, all then unvested stock options, restricted stock grants and stock appreciation rights held by Executive shall be immediately forfeited. F.

Remedies Not Exclusive. The rights, remedies and benefits herein expressly specified are cumulative and not exclusive of any rights, remedies or benefits which any party may otherwise have. 17. Invalid Provisions. The invalidity of any one or more of the clauses or words contained in this Agreement shall not affect the reasonable enforceability of the remaining provisions of this Agreement, all of which are inserted herein conditionally upon being valid in law; and in the event that one or more of the words or clauses contained herein shall be invalid, this instrument shall be construed as if such invalid words or clauses had not been inserted or, alternatively, said words or clauses shall be reasonably limited to the extent that the applicable court interpreting the provisions of this Agreement considers to be reasonable. 18.

Miscellaneous. This Agreement shall be construed under and governed by the laws of the State of Nevada other than its conflicts of laws principles. This Agreement contains the complete understanding of the parties with respect to the subject matter of this Agreement and supersedes all other prior agreements, understandings and negotiations relating to the same subject matter. This Agreement may only be modified by a written instrument signed by each of the parties hereto. No provisions of this Agreement will be interpreted in favor of, or against, any of the parties hereto by reason of the extent to which any such party or its counsel participated in the drafting thereof or by reason of the extent to which any such provision is inconsistent with any prior draft hereof or thereof. Failure to require strict compliance with any term or provision of this Agreement shall not constitute a waiver of a party’s right to insist upon strict compliance with each and every provision of this Agreement. No waiver of any terms and conditions of this Agreement shall be deemed to be a waiver of any subsequent breach of that or any other term of condition. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original, but all of which together shall constitute one and same instrument. The provisions of Item 3 (the last paragraph), 6H, 7, 8, 9, 11 and 14 through 21 shall survive the termination of this Agreement and Executive’s employment with the Company. This Agreement may be executed by any party by delivery of a facsimile signature, which signature shall have the same force as an original signature. Any party which delivers a facsimile signature shall promptly thereafter deliver an originally executed signature to the other party; provided, however, that the failure to deliver an original signature page shall not affect the validity of any signature delivered by facsimile. The paragraph headings contained in this Agreement are for reference only and shall not be deemed to impart substantive meeting to any provision of this Agreement. Each party has had the opportunity to be represented by counsel of its choice in negotiating this Agreement. This Agreement shall therefore be deemed to have been negotiated and prepared at the joint request and direction of the parties, at arm’s length, with the advice and participation of counsel, and shall be interpreted in accordance with its terms and without favor to any party.

- 17 - Exhibit A Form of Release THIS RELEASE (the “Release”) is entered into between Xxxx Xxxxxx (“Executive”) and Allegiant Travel Company, a Nevada corporation (the “Company”), for the benefit of the Company. The entering into and non-revocation of this Release is a condition to Executive’s right to receive certain payments under Items 6A, 6C and 6D of the Employment Agreement entered into by and between Executive and the Company, effective as of December 1, 2022 (the “Employment Agreement”). Capitalized terms used and not defined herein shall have the meaning provided in the Employment Agreement. Accordingly, Executive and the Company agree as follows. 1. In consideration for the compensation and other benefits provided to Executive under Items 6A, 6C and 6D (as applicable) of the Employment Agreement to which Executive would not otherwise be entitled, Executive represents and agrees, as follows: (a) Executive, for himself, his heirs, administrators, representatives, executors, successors and assigns (collectively “Releasors”), hereby irrevocably and unconditionally releases, acquits and forever discharges and agrees not to sue the Company or any of its subsidiaries, divisions, affiliates and related entities and its current and former directors, officers, shareholders, trustees, employees, consultants, independent contractors, representatives, agents, servants, successors and assigns and all persons acting by, through or under or in concert with any of them (collectively “Releasees”), from all claims, rights and liabilities up to and including the date of this Release arising from or relating to Executive’s employment with, or termination of employment from, the Company, under the Employment Agreement and from any and all charges, complaints, claims, liabilities, obligations, promises, agreements, controversies, damages, actions, causes of actions, suits, rights, demands, costs, losses, debts and expenses of any nature whatsoever, known or unknown, suspected or unsuspected and any claims of wrongful discharge, breach of contract, implied contract, promissory estoppel, defamation, slander, libel, tortious conduct, employment discrimination or claims under any federal, state or local statute, law, order or ordinance, including any rights or claims arising under Title VII of the Civil Rights Act of 1964, as amended, the Age Discrimination in Employment Act of 1967, as amended, 29 U.S.C. § 621 et seq. (“ADEA”), or any other federal, state or municipal ordinance. Nothing contained herein shall restrict the parties’ rights to enforce the terms of this Release. (b) To the maximum extent permitted by law, Executive agrees that he has not filed, nor will he ever file, a lawsuit asserting any claims which are released by this Release. (c) Notwithstanding the foregoing, this Release specifically excludes (i) any unpaid compensation or benefits accrued through the date of Executive’s termination of employment, (ii) Executive’s rights and the Company’s obligations under Items 6A, 6C and 6D (as applicable) of the Employment Agreement, (iii) claims for unemployment benefits, (iv) Executive’s vested account balance, if any, in the Company’s 401(k) plan, and (v) Executive’s right, if any, to elect continued group health coverage for himself and his eligible family members under Part 6 of Title I of ERISA. Nothing contained in this Release shall release Executive from

- 18 - his obligations, including any obligations to abide by restrictive covenants under the Employment Agreement or any other agreement that continue or are to be performed following termination of employment. (d) The parties agree that this Release shall not affect the rights and responsibilities of the US Equal Employment Opportunity Commission (hereinafter “EEOC”) to enforce ADEA and other laws. In addition, the parties agree that this Release shall not be used to justify interfering with Executive’s protected right to file a charge or participate in an investigation or proceeding conducted by the EEOC. The parties further agree that Executive knowingly and voluntarily waives all rights or claims (that arose prior to Executive’s execution of this Release) the Releasors may have against the Releasees, or any of them, to receive any benefit or remedial relief (including, but not limited to, reinstatement, back pay, front pay, damages, attorneys’ fees, experts’ fees) as a consequence of any investigation or proceeding conducted by the EEOC. 2. Executive acknowledges that the Company has specifically advised him of the right to seek the advice of an attorney concerning the terms and conditions of this Release. Executive further acknowledges that he has been furnished with a copy of this Release, and he has been afforded twenty-one (21) days in which to consider the terms and conditions set forth above prior to this Release. By executing this Release, Executive affirmatively states that he has had sufficient and reasonable time to review this Release and to consult with an attorney concerning his legal rights prior to the final execution of this Release. Executive further agrees that he has carefully read this Release and fully understands its terms. Executive understands that he may revoke this Release within seven (7) days after signing this Release. Revocation of this Release must be made in writing and must be received by [●] at [●] within the time period set forth above. 3. This Release will be governed by and construed in accordance with the laws of the state of Nevada, without giving effect to any choice of law or conflicting provision or rule (whether of the state of Nevada or any other jurisdiction) that would cause the laws of any jurisdiction other than the state of Nevada to be applied. In furtherance of the foregoing, the internal law of the state of Nevada will control the interpretation and construction of this agreement, even if under such jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply. The provisions of this Release are severable, and if any part or portion of it is found to be unenforceable, the other paragraphs shall remain fully valid and enforceable. This Release shall become effective and enforceable on the eighth day following its execution by Executive, provided he does not exercise his right of revocation as described above. If Executive fails to sign and deliver this Release or revokes his signature, this Release will be without force or effect, and Executive shall not be entitled to those payments or benefits under Items 6A, 6C or 6D of the Employment Agreement, as applicable, which are conditioned upon the execution of this Release.
