ALLEGIANT TRAVEL COMPANY ANNOUNCES LAUNCH OF TENDER OFFER AND CONSENT SOLICITATION FOR ITS 7.250% SENIOR SECURED NOTES DUE 2027

LAS VEGAS, June 9, 2026 /PRNewswire/ — Allegiant Travel Company (NASDAQ: ALGT) (the “Company,” “we,” “us,” or “our”) announced today that it is commencing a tender offer (the “Tender Offer”) to purchase for cash any and all of its outstanding $403,009,000 remaining aggregate principal amount of 7.250% Senior Secured Notes Due 2027 (the “Notes”). In connection with the Tender Offer, the Company is also seeking consents (the “Consent Solicitation”) to proposed amendments (the “Proposed Amendments”) to the Indenture, dated as of August 17, 2022 (the “Indenture”), which governs the Notes, that would eliminate most of the restrictive covenants and certain events of default applicable to the Notes, and amend certain other provisions applicable to the Notes.

Information related to the Notes and other information relating to the Tender Offer and Consent Solicitation are listed in the table below. The terms and conditions of the Tender Offer and Consent Solicitation are described in greater detail in the Offer to Purchase and Consent Solicitation Statement, dated June 9, 2026 (the “Statement”), which holders of the Notes (each a “Holder” and collectively the “Holders”) should carefully read before making any decision with respect to the Tender Offer and Consent Solicitation.

Holders who validly tender their Notes and thereby deliver their consents at or prior to 5:00 p.m., New York City time, on June 23, 2026, unless extended or earlier terminated by the Company (the “Early Tender Deadline”) will be eligible to receive total consideration (the “Total Consideration”) of $1,005.00 per $1,000 principal amount of Notes, which includes the consideration for the Notes validly tendered (and not validly withdrawn), pursuant to the Statement, of $955.00 per $1,000 principal amount of such Notes (the “Tender Offer Consideration”) and the early tender premium of $50.00 per $1,000 principal amount of such Notes (the “Early Tender Premium”). Holders must validly tender and not validly withdraw their Notes, and have their Notes accepted for purchase in the Tender Offer, at or prior to the Early Tender Deadline in order to be eligible to receive the Total Consideration. A Holder cannot deliver a consent with respect to the Notes without tendering its corresponding Notes or tender its Notes without delivering a corresponding consent. Holders of Notes who tender their Notes will be deemed by virtue of such tender to have delivered their consent to the Proposed Amendments.

Holders who validly tender their Notes after the Early Tender Deadline, but at or prior to 5:00 p.m., New York City time, on July 9, 2026, unless extended or earlier terminated by the Company (such time and date as the same may be extended or earlier terminated, the “Expiration Time”) will be eligible to receive only the Tender Offer Consideration, plus accrued and unpaid interest, for such Notes if such Notes are accepted for purchase, and will not be entitled to the Early Tender Premium.

Upon the terms and subject to the conditions described in the Statement, the Company reserves the right, but is under no obligation, at any point after the Early Tender Deadline and at or before the Expiration Time, to accept for purchase any Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Deadline (the settlement date of such purchase, the “Initial Settlement Date”). The Initial Settlement Date, if the Company chooses to exercise its option to have an Initial Settlement Date, for the Tender Offer will be determined at the Company’s option and will be a business day the Company chooses after both the Early Tender Deadline and the satisfaction or waiver of the conditions to consummation of the Tender Offer and the Consent Solicitation, and is currently expected to be June 24, 2026 unless extended by the Company. Upon the terms and subject to the conditions described in the Statement, Notes validly tendered after the Early Tender Deadline but at or before the Expiration Time, will be accepted for purchase promptly after the Expiration Time. If the Company elects not to have an Initial Settlement Date, it will purchase all Notes validly tendered and not withdrawn, if it purchases any at all, on the Final Settlement Date.

Holders whose Notes are accepted for purchase pursuant to the Tender Offer will receive accrued and unpaid interest from the last interest payment date on such purchased Notes up to, but not including, the date on which such Notes are purchased.

With respect to any Notes not purchased in the Tender Offer, the Company may choose, but has no obligation, to satisfy and discharge the Indenture by sending a notice of redemption to the Trustee under the Indenture for the redemption of all outstanding Notes on August 15, 2026, at a price equal to 100.00% of the aggregate principal amount of the Notes to be redeemed, plus accrued and unpaid interest up to, but not including, the date of redemption.

Tendered Notes may be withdrawn, and consents thereby revoked, at any time at or before the Early Tender Deadline. Holders who tender their Notes after the Early Tender Deadline, but on or prior to the Expiration Time, may not withdraw their tendered Notes, except in certain limited circumstances where additional withdrawal rights are required by law. A valid withdrawal of tendered Notes will constitute the concurrent valid revocation of such Holder’s related consent.

If the Company receives the written consent of the Holders of at least a majority in principal amount of the outstanding Notes to the Proposed Amendments, the Company will promptly after the Early Tender Deadline execute a supplement to the Indenture (the “Supplemental Indenture”) in order to effect the Proposed Amendments. The Supplemental Indenture will become effective on the Initial Settlement Date or, if there is no Initial Settlement Date, on the Final Settlement Date. The Supplemental Indenture is described in greater detail in the Statement.

The Tender Offer and Consent Solicitation are conditioned upon the satisfaction of certain conditions, including the Company successfully completing a debt financing as described in the Statement. Subject to applicable law, the Company may also extend, amend or terminate the Tender Offer and Consent Solicitation at any time before the Expiration Time in its sole discretion.

The Company has retained Barclays Capital Inc. to act as dealer-manager and solicitation agent for the Tender Offer and Consent Solicitation. Global Bondholder Services Corporation will act as the Information Agent and the Tender Agent for the Tender Offer and Consent Solicitation. Questions regarding the Tender Offer and Consent Solicitation should be directed to Barclays Capital Inc. at (212) 528-7581 (collect) or (800) 438-3242 (toll-free).
