Exhibit 99.1

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The Transactions. On

January 11, 2026, Sun Country Airlines Holdings, Inc. (“Sun Country”), Allegiant Travel Company (“Allegiant”), and two wholly owned subsidiaries of Allegiant, Mirage Merger Sub, Inc. and Sawdust Merger Sub, LLC, entered into an Agreement and Plan

of Merger (the “Merger Agreement”). The Merger Agreement provided, among other things, for the acquisition of Sun Country by Allegiant through two mergers: (i) first, Mirage Merger Sub, Inc. would merge with and into Sun Country, with Sun Country

surviving as a direct, wholly owned subsidiary of Allegiant (the “First Merger”); and (ii) second, immediately after the first merger, Sun Country would merge with and into Sawdust Merger Sub, LLC (“Merger Sub II”), with Merger Sub II surviving as

a direct, wholly owned subsidiary of Allegiant (the “Second Merger” and, together with the First Merger, the “Mergers”). The Mergers were completed on May 13, 2026 (the “Closing Date”). See Note 1 to the unaudited pro forma condensed combined

financial information.

Merger Consideration.

For a description of the Merger Consideration, as defined below, in connection with the transactions, see Note 1 to the unaudited pro forma condensed combined financial information.

Treatment of Sun Country

Equity Awards. For a description of the treatment of Sun Country equity awards in connection with the transactions, see Note 1 to the unaudited pro forma condensed combined financial information.

Pro forma financial

information. The following unaudited pro forma condensed combined statements of income (loss) (referred to as the “pro forma income statements”) for

the three months ended March 31, 2026, and for the year ended December 31, 2025, which combine the historical consolidated statements of income of Allegiant and Sun Country, after giving effect to the transactions and other adjustments (as

described in the notes to the unaudited pro forma condensed combined financial information) as if they occurred on January 1, 2025. The unaudited pro forma condensed combined statement of financial position (referred to as the “pro forma balance

sheet”) as of March 31, 2026, which combines the historical condensed consolidated statements of financial position of Allegiant and Sun Country, after giving effect to the transactions and other adjustments (as described in the notes to the

unaudited pro forma condensed combined financial information) as if they had occurred on March 31, 2026. The pro forma income statements and pro forma balance sheet are collectively referred to as the “pro forma financial information”.

The pro forma financial information was prepared for illustrative and informational purposes only, in accordance with Regulation S-X

Article 11, to demonstrate the estimated effects of the transactions and adjustments (referred to as “transaction accounting adjustments”), such as (i) the alignment of Sun Country’s statement of operations and financial position amounts to

Allegiant’s presentation, (ii) adjustments based upon preliminary estimates of the fair value of assets to be acquired and liabilities to be assumed, (iii) transaction costs expected to be incurred by Allegiant, and (iv) the associated income tax

impacts of recognizing these adjustments. The pro forma financial information was prepared using the acquisition method of accounting in accordance with U.S. Generally Accepted Accounting Principles (GAAP) with Allegiant identified as the

accounting acquirer. The transaction accounting adjustments do not reflect any potential costs that may be incurred or benefits to be realized in connection with the Mergers, such as synergies, cost savings, innovation, and operational

efficiencies; as well as potential post-merger costs, such as restructuring and integration charges.

The pro forma financial information is based on various adjustments and assumptions and is not necessarily indicative of what the

combined statements of income or financial position would have actually been had the transaction accounting been completed as of the dates indicated above. Further, the pro forma financial information does not purport to project the future

financial position or results of operations of the combined company after the transactions, which may differ materially and adversely from the pro forma financial information.

The pro forma financial information reflects transaction accounting adjustments that Allegiant believes are necessary to present

fairly the pro forma income statements and pro forma balance sheet following the completion of the transactions as of and for the periods indicated above. As of the date of this filing, the necessary valuations to arrive at the required final

estimates of the fair value and the related allocation of purchase price to acquired assets and liabilities have not been finalized, nor have all adjustments necessary to conform Sun Country’s accounting policies to those of Allegiant been

identified. The value of Allegiant’s Common Stock distributed as of the Closing Date has been determined based on the market price of Allegiant’s Common Stock on the Closing Date. The pro forma adjustments are preliminary and are subject to change

as additional information becomes available and as additional analysis is performed. The final purchase price allocation and measurement of Merger Consideration may be materially different than that reflected herein.

The pro forma financial information should be read in conjunction with the accompanying notes. In addition, the pro forma financial

information was based on, and should be read in conjunction with, the following historical consolidated financial statements and accompanying notes:

The audited consolidated financial statements of Allegiant as of and for the year ended December 31, 2025 and the related notes, as included in

Allegiant’s Annual Report on Form 10-K as filed with the SEC on February 26, 2026;

The audited consolidated financial statements of Sun Country as of and for the year ended December 31, 2025 and the related notes, as included in

Sun Country’s Annual Report on Form 10-K as filed with the SEC on February 12, 2026;

The unaudited condensed consolidated financial statements of Allegiant as of and for the three months ended March 31, 2026 and the related notes, as

included in Allegiant’s Quarterly Report on Form 10-Q as filed with the SEC on May 6, 2026; and

The unaudited condensed consolidated financial statements of Sun Country as of and for the three months ended March 31, 2026 and the related notes,

as included in Sun Country’s Quarterly Report on Form 10-Q as filed with the SEC on May 1, 2026.

ALLEGIANT TRAVEL COMPANY

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

(in thousands, except per share amounts)

Note 1 – Description of the Mergers

On May 13, 2026, as part of the First Merger, Mirage Merger Sub, Inc. was merged with and into Sun Country, with Sun Country

surviving as a wholly owned subsidiary of Allegiant. Immediately after the First Merger, Sun Country merged with and into Merger Sub II as part of the Second Merger, with Merger Sub II surviving as a wholly owned subsidiary of Allegiant.

Pursuant to the terms and conditions of the Merger Agreement, at the effective time of the First Merger (the “Effective Time”), each

share of Sun Country common stock, par value $0.01 per share (“Sun Country Common Stock”), was converted into the right to receive $4.10 in cash, without interest (the “Cash Consideration”) and 0.1557 (the “Merger Exchange Ratio”) shares of

Allegiant common stock, par value $0.001 per share (“Allegiant Common Stock”) (the “Stock Consideration” and, together with the Cash Consideration, the “Merger Consideration”).

Treatment of Sun Country Equity Awards

Pursuant to the terms and conditions of the Merger Agreement, effective as of immediately prior to the consummation of the First

Merger (the “First Effective Time”), by virtue of the Mergers:

All outstanding stock options to purchase a share of Sun Country Common Stock granted pursuant to any equity award plans of Sun Country (“Sun Country Equity Award

Plans”) (each a “Sun Country Stock Option”), regardless of exercise price, were automatically converted into stock options to purchase Allegiant Common Stock (each an “Allegiant Stock Option”) immediately before the closing, with no action

required by the holder (the “Converted Options” and each a “Converted Option”). Each Converted Option covers a proportionately adjusted number of shares of Allegiant Common Stock based on a ratio as determined under the Merger Agreement of

approximately 0.2057 Allegiant Stock Option for one Sun Country Stock Option, has a proportionately adjusted exercise price, and is otherwise subject to the same terms and conditions as the Sun Country Stock Option;

Unless otherwise agreed with the holder of the award, each outstanding award of restricted stock units denominated in Sun Country Common Stock subject to time-based

vesting restrictions (each a “Sun Country RSU Award”) granted pursuant to the Sun Country Equity Award Plans was assumed by Allegiant and converted into an Allegiant restricted stock unit award  (each an “Allegiant RSU Award”) denominated

in Allegiant Common Stock, based on a ratio as determined under the Merger Agreement of approximately 0.2057 Allegiant RSU Awards for one Sun Country RSU Award. The Allegiant RSU Awards otherwise have the same terms and conditions as the

Sun Country RSU Awards, including any double‑trigger vesting protections;

Unless otherwise agreed with the holder of the award, each outstanding restricted stock unit award denominated in Sun Country Common Stock subject to

performance-based vesting restrictions (each a “Sun Country PRSU Award”) granted pursuant to the Sun Country Equity Award Plans was assumed by Allegiant and converted into an Allegiant time-based restricted stock unit award (each an

“Allegiant PRSU Award”) denominated in Allegiant Common Stock, based on a ratio as determined under the Merger Agreement of approximately 0.2057 Allegiant PRSU Awards for one Sun Country PRSU Award and converted based on an average

performance factor of 125%. The Allegiant PRSU Awards have the same terms and conditions as the Sun Country PRSU Awards, including any double‑trigger vesting protections, provided that there are no longer any performance-based vesting

conditions, and the Allegiant PRSU Awards are time-vesting awards eligible to vest on the last day of the performance period applicable to the Sun Country PRSU Award; and

With respect to non-employee Sun Country board members and former employees/service providers to Sun Country, each Sun Country Equity Award held by such individuals

(each a “Non-Employee Sun Country Equity Award”) was fully vested (to the extent not yet vested), cancelled and converted into the right to receive Merger Consideration.

Treatment of Sun Country Warrant

Pursuant to the Warrant to Purchase Shares, dated as of December 13, 2019, as amended, by and between Amazon.com NV Investment

Holdings LLC (“Amazon Holder”) and Sun Country (the “Sun Country Warrant”), Sun Country issued warrants to Amazon Holder to purchase an aggregate of up to 9,482,606 shares of Sun Country Common Stock at an exercise price of approximately $15.17 per

share.

Pursuant to the terms of the Sun Country Warrant, any unvested warrant shares of the Sun Country Warrant became fully vested and

immediately exercisable immediately prior to the consummation of the Mergers. The Sun Country Warrant was exercised as of immediately prior to the consummation of the Mergers on a net issuance exercise basis, and Amazon Holder received Merger

Consideration of $12.3 million in form of Allegiant’s Common Stock  and $3.9 million in form of Cash Consideration as a result of the exercise of the Sun Country Warrant.

Accordingly, the stock issuance and cash consideration issued in respect of the Sun Country Warrant is included in the preliminary

consideration transferred. The expected loss on the settlement of the Sun Country Warrant is also reflected in the pro forma financial information.

Change-in-Control Payments

In conjunction with the Mergers, Allegiant is required to make certain change-in-control, retention and termination payments to

employees of Sun Country (“Change-in-Control Payments”). Included in the Change-in-Control Payments are the payments below which are treated as post-combination expense of Allegiant.

Retention bonuses of $9.4 million, of which $5.4 million has vested and paid following the Closing Date, and an additional $4.0 million will be paid 90 days after

the Closing Date;

Pro-rated annual incentive bonuses of $2.7 million to be paid within 30 days after the Closing Date;

Change-in-control bonuses of $0.8 million, subject to continued employment through the payment date and are expected to be paid after the Closing Date on each

applicable payment date.

Dispatcher bonuses of $2.0 million to eligible employees, and subject to the achievement of certain milestones, are estimated to be paid two years after the Closing

Date.

Severance payable to Sun Country’s officers

Certain officers of Sun Country were terminated as a result of the Mergers. In accordance with the preexisting terms outlined in

their employment or separation agreements, which included provisions that require certain cash payments and accelerated vesting of equity-based awards upon both a change of control event and a subsequent termination (“dual-trigger arrangements”),

these officers were entitled to cash severance payments of $5.3 million which are recognized as post-combination expense by Allegiant.

Settlement of Tax receivable liability

In connection with the Mergers, Allegiant did not legally assume Sun Country’s outstanding tax receivable liability; however, Allegiant settled such

liability in cash for $80.5 million on the Closing Date. As the settlement was made for the benefit of Sun Country, the amount has been included as a component of the preliminary consideration transferred.

Note 2 – Basis of Presentation

The pro forma financial information was prepared in accordance with Article 11 of Regulation S-X. The historical consolidated

financial statements of Allegiant and the historical consolidated financial statements of Sun Country were prepared in accordance with U.S. GAAP and presented in U.S. dollars.

The unaudited pro forma condensed combined balance sheet as of March 31, 2026, gives effect to the Mergers as if they had been

completed on March 31, 2026, and combines the condensed consolidated balance sheet of Allegiant as of March 31, 2026 with the condensed consolidated balance sheet of Sun Country as of March 31, 2026.

The unaudited pro forma condensed combined statements of income for

the three months ended March 31, 2026, and for the year ended December 31, 2025 gives effect to the Mergers as if they had been completed on January 1, 2025. The unaudited pro forma condensed combined statement of income for the three months

ended March 31, 2026, and for the year ended December 31, 2025 combines the condensed consolidated statement of income of Allegiant for the three months ended

March 31, 2026, and for the year ended December 31, 2025 and the condensed consolidated statement of operations of Sun Country for the three months ended March

31, 2026, and for the year ended December 31, 2025.

Additionally, as discussed in Note 3, certain reclassifications were made to conform the historical presentation of Sun Country

consolidated financial statements to that of Allegiant’s financial statement presentation. The accounting policies used in the preparation of the pro forma financial information are those set out in Allegiant’s audited financial statements for the

year ended December 31, 2025. Management conducted a preliminary evaluation of accounting policies used by Sun Country compared to accounting policies used by Allegiant and identified an accounting policy difference related to the recognition of

maintenance expenses, which is primarily attributed to airframe heavy maintenance, as discussed in Note 5. Allegiant has historically deferred these costs and recognized them over the life of the applicable property and equipment, while Sun Country

has historically expensed airframe heavy maintenance amounts as incurred and capitalized engine overhauls under the built-in overhaul method. Management also identified an accounting policy difference related to the classification of investments,

as Allegiant classifies investments with maturities greater than one year as long-term, while Sun Country historically classified available-for-sale investments, which are held to support current operations, as short-term, as discussed in Note 5.

Management did not identify any other material differences in the companies’ accounting policies. Since the completion of the Mergers, Allegiant is conducting a comprehensive review of Sun Country’s accounting policies, and as a result of that

review, Allegiant may identify differences, which may differ materially from the information presented herein.

The pro forma financial information reflects the pro forma

effect of the Mergers using the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations (“ASC 805”), with Allegiant as the accounting acquirer, using

the fair value concepts defined in ASC Topic 820, Fair Value Measurement, and is based on the historical financial statements of Allegiant and Sun Country. Refer to Note 4 for additional information regarding the accounting treatment of the Mergers and preliminary purchase price allocation.

The pro forma financial information is presented for informational purposes only and are not necessarily indicative of the operating

results or financial position that would have been achieved had the Mergers been consummated on the dates indicated or that the combined company may achieve in future periods. The pro forma financial information does not reflect any anticipated

synergies or dis-synergies, operating efficiencies or cost savings that may result from the Mergers, or any integration costs that may be incurred. The transaction accounting adjustments represent management’s best estimates and are based upon

currently available information and certain assumptions that management believes are reasonable and supportable. As the pro forma financial information has been prepared based on these assumptions, the final amounts recorded may differ materially

from the information presented herein.

Certain amounts included herein have been subject to rounding adjustments. Accordingly, amounts shown as totals in certain tables

may not be the arithmetic aggregation of the amounts that precede them.

Note 3 –Reclassification Adjustments

Reclassification adjustments have been made to conform Sun Country’s historical financial statement presentation to Allegiant’s

financial statement presentation in the unaudited pro forma condensed combined balance sheet and the unaudited pro forma condensed combined statement of income.

Unaudited Pro Forma Condensed Combined Balance Sheet as of March 31, 2026

The following table presents a summary of reclassification adjustments to conform Sun Country’s historical condensed consolidated balance sheet

information for the three months ended March 31, 2026 with Allegiant’s historical condensed consolidated balance sheet presentation for the three months ended March 31, 2026 (in thousands):

Note 4 – Accounting Treatment and Preliminary Purchase Price Allocation

Under ASC 805, all assets acquired and liabilities assumed in a business combination are recognized and measured at their

acquisition date fair values, and transaction costs associated with the business combination are expensed as incurred. The excess of preliminary consideration transferred over the estimated fair value of identifiable assets acquired and liabilities

assumed, if any, is allocated to goodwill.

The preliminary consideration transferred calculated in accordance with ASC 805 is based on the Merger Consideration, as delineated

in the Merger Agreement, and other items, as applicable.

In accordance with ASC 805, Allegiant has assigned fair value to

assets acquired and liabilities assumed using best estimates and assumptions as of the Closing Date. The determination of the estimated fair value of assets acquired requires significant judgment and often involves the use of various estimates

and assumptions. To determine the preliminary estimate of fair values of assets acquired and liabilities assumed, management used benchmark studies in addition to the historical unaudited balance sheet of Sun Country as of March 31, 2026,

collectively with the consequential tax effects of the Mergers.

The estimated fair values and purchase price allocation are preliminary and a final determination of the fair value of assets

acquired, including any property and equipment, identifiable intangible assets, and liabilities assumed as of the acquisition date will be performed within one year of the Closing Date. Since the pro forma financial information has been prepared

based on preliminary fair values, the final amounts may differ materially from the information presented herein.

A net loss cannot be diluted. When a company is in a net loss position, basic and diluted loss per share are the same. The 8.45

million shares of Allegiant Common Stock to be issued in connection with the Mergers and 0.42 million shares of Allegiant Common Stock expected to be issued in connection with the acceleration of Sun Country’s equity awards, which includes the Sun

Country RSU Awards, Sun Country PRSU Awards, and Sun Country Stock Options, and the 0.15 million shares of Allegiant Common Stock expected to be issued to Amazon Holder as part of the settlement of the Sun Country Warrant are assumed to be

outstanding for the entirety of the period presented.

The computation of pro forma diluted weighted-average shares outstanding for the year ended December 31, 2025, excludes

approximately 0.1 million shares that would have resulted from the conversion of Allegiant’s 2014 Employee Stock Purchase Plan (“ESPP”), unvested Allegiant RSU Awards, and Allegiant equity awards issued to replace Sun Country equity awards under

the treasury stock method because the effect would have been anti-dilutive. Upon Allegiant generating net income in future years, the denominator of a diluted earnings per share calculation will include both the weighted average number of shares

outstanding and the number of common stock equivalents, if the inclusion of such common stock equivalents would be dilutive.

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).  Requests for documentation should be directed to Global Bondholder Services Corporation at (855) 654-2014 (toll-free), (212) 430-3774 (banks and brokers) or contact@gbsc-usa.com.

This press release does not constitute a notice of redemption with respect to the Notes.

This press release is not an offer to buy any securities and does not constitute a solicitation of consents of Holders and shall not be deemed an offer to buy or a

solicitation of consents with respect to any other securities of the Company. The Tender Offer and Consent Solicitation will be made solely pursuant to the Offer to Purchase and Consent Solicitation Statement and the accompanying Consent and Letter

of Transmittal.  All statements herein regarding the terms of the Tender Offer and Consent Solicitation, the Proposed Amendments, the Supplemental Indenture and the Indenture are qualified in their entirety by reference to the text of the Offer to

Purchase and Consent Solicitation Statement and the accompanying Consent and Letter of Transmittal, the Supplemental Indenture and the Indenture. The completion of the Tender Offer and the Consent Solicitation and the execution of the Supplemental

Indenture are subject to the conditions set forth in the Offer to Purchase and Consent Solicitation Statement. There can be no assurance that either of the Tender Offer or the Consent Solicitation will be consummated.
