Unaudited Pro Forma Information
The following presents certain unaudited pro forma condensed combined statements of income (loss) for the three month periods ended March 31, 2025, June 30, 2025, September 30, 2025, December 31, 2025, March 31, 2026 and June 30, 2026, and for the year ended December 31, 2025, and other unaudited pro forma non-GAAP information for the same periods. The pro forma financial information is based upon the combined historical financial statements of Allegiant Travel Company, ("Allegiant") and Sun Country Airlines Holdings, LLC, (“Sun Country”), after giving effect to Allegiant’s acquisition of all the issued and outstanding shares of Sun Country by means of a merger (the “Merger”). The combined pro forma information includes adjustments prepared in accordance with Article 11 of Regulation S-X to illustrate the effects of the Merger as if it had occurred on January 1, 2025, the beginning of the earliest period presented.
On September 4, 2025, the Company completed the sale of Sunseeker Resort (“Sunseeker”). In addition to the adjustments arising from the Merger described above, the combined pro forma information includes adjustments to illustrate the effects of the sale of Sunseeker Resort as if it had occurred on January 1, 2025, the beginning of the earliest period presented.
Management believes pro forma combined operating results for prior periods are useful for the purpose of comparing our actual or expected future operating results, as it provides a relevant baseline for identifying trends in the overall operating performance of our business. Management also believes the recalculation of certain operating statistics, unit metrics and certain non-GAAP measures on a pro forma basis to be useful in a review of our operating results.
The Sun Country Transaction Accounting Adjustments in the unaudited pro forma condensed combined statements of income (loss) reflect the preliminary allocation of the purchase price to the acquired assets and liabilities based upon estimates of fair values. These adjustments have been tax effected using an assumed blended effective tax rate for each period. These adjustments are provisional and subject to further adjustment through May 13, 2027 as additional information becomes available, additional analyses are performed and as warranted by changes in current conditions and future expectations. Differences between these preliminary estimates and the final acquisition accounting may occur and these differences could have a material impact on the unaudited pro forma condensed combined financial information and the combined company’s future results of operations.
The Sun Country Reclassification Adjustments in the unaudited pro forma condensed combined statements of income (loss) reflect the reclassification of historically reported amounts to conform to Allegiant presentation. Differences from previously filed pro forma information reflects the impact of permissible measurement period adjustments and certain immaterial line item reclassifications to better conform presentation.
The Sunseeker Transaction Accounting Adjustments in the unaudited pro forma condensed combined statements of income (loss) reflect the removal of profit and loss attributable to Sunseeker Resort after the January 1, 2025 (assumed) date of disposition. There were no material impacts to profit and loss on the date of the sale of the Resort.
The unaudited pro forma condensed combined financial information is presented for informational purposes only. Such information is not necessarily indicative of the operating results that actually would have been achieved if the Merger had been consummated on the dates indicated or that the combined company may achieve in future periods. Specifically, the unaudited pro forma condensed combined financial information does not include any projected synergies expected to be achieved as a result of the Merger or any associated costs that may be incurred to achieve any projected synergies. The unaudited pro forma condensed combined financial information also excludes future costs associated with any integration activities that may result from the Merger, to the extent those costs are not included in the post-acquisition periods.
