Item 2.02.    Results of Operations and Financial Condition.
On July 16, 2024, Spirit Airlines, Inc. (the "Company" or "Spirit") provided an update to investors (the "Investor Update") announcing certain preliminary estimates and guidance for the second quarter 2024. The Company’s unaudited interim consolidated financial statements for the second quarter 2024 are not yet complete and results for second quarter 2024 may vary from these preliminary estimates upon completion of closing procedures and finalization of the unaudited interim unconsolidated financial statements.
Non-GAAP financial measures that reflect adjustments from historical financial data prepared under GAAP, including adjustments for special items, are included in the Investor Update as supplemental disclosures because the Company believes they are useful indicators of the Company's operating performance for comparative purposes. These non-GAAP financial measures are well recognized performance measurements in the airline industry that are frequently used by investors, securities analysts and other interested parties in comparing the operating performance of companies in the airline industry. The non-GAAP financial measures provided have limitations as an analytical tool. Because of these limitations, non-GAAP financial measures should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP. The Company has also provided in the Investor Update reconciliations of these non-GAAP financial measures to the appropriate GAAP financial measures.
A copy of the Investor Update is attached hereto as Exhibit 99.1 and is incorporated by reference into this Item 2.02. The information contained in Item 2.02 of this Current Report on Form 8-K and Exhibit 99.1 attached hereto is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”). It may only be incorporated by reference in another filing under the Exchange Act or the Securities Act of 1933, as amended (the "Securities Act"), if such subsequent filing specifically references the information furnished pursuant to Item 2.02 of this report.
Item 7.01.    Regulation FD Disclosure.
On July 16, 2024, the Company posted a copy of the Investor Update providing certain preliminary estimates and guidance for the second quarter 2024 (as described in Item 2.02 above) and full year 2024 guidance and other items on its investor relations website at https://ir.spirit.com. A copy of the Investor Update is furnished pursuant to this Item 7.01 as Exhibit 99.1 to this Current Report on Form 8-K and incorporated by reference herein in its entirety. The guidance provided therein is only an estimate of what the Company believes is realizable as of the date of the Investor Update. Investors are encouraged to read the Investor Update. The Company reserves the right to discontinue availability of the Investor Update from its website at any time.
Pursuant to General Instruction B.2. to Form 8-K, the information set forth in this Current Report on Form 8-K, including Exhibit 99.1 shall not be deemed "filed" for purposes of Section 18 of the Exchange Act or otherwise subject to the liabilities thereof, nor shall it be incorporated by reference into future filings by the Company under the Exchange Act or under the Securities Act, except to the extent specifically provided in any such filing. Additionally, the submission of the information set forth in this Item 7.01 is not deemed an admission as to the materiality of any information in this Current Report on Form 8-K that is required to be disclosed solely by Regulation FD.
