Item 7.01 Regulation FD Disclosure.

Monthly Operating Report

As previously disclosed, on August 29, 2025, Spirit Aviation Holdings, Inc. (“the Company”) and its subsidiaries (such subsidiaries, each a “Debtor,” collectively) filed voluntary petitions for relief under chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”). The Debtors’ chapter 11 cases (the “Chapter 11 Cases”) are being jointly administered for procedural purposes only under case number 25-11897 (SHL).

On November 18, 2025, the Company filed its monthly operating report for the months ended August 31, 2025 and September 30, 2025 (the “Monthly Operating Report”) with the Bankruptcy Court. The Monthly Operating Report is attached hereto as Exhibit 99.1 and is incorporated herein by reference. This current report (including the exhibits hereto or any information included therein) shall not be deemed an admission as to the materiality of any information required to be disclosed solely by reason of Regulation FD.

Additional information about the Chapter 11 Cases, and copies of all documents publicly filed in the Chapter 11 Cases (including the Monthly Operating Report), can be accessed free of charge at https://dm.epiq11.com/SpiritAirlines.

The information included in this Current Report on Form 8-K under Item 7.01 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”), or otherwise subject to liabilities of that Section, unless the registrant specifically states that the information is to be considered “filed” under the Exchange Act or incorporates it by reference into a filing under the Exchange Act or the Securities Act of 1933, as amended.

Cautionary Statement Regarding Financial and Operating Data

The Company cautions investors and potential investors not to place undue reliance upon the information contained in the Monthly Operating Report, which was not prepared for the purpose of providing the basis for an investment decision relating to any of the Debtors’ securities. In particular, the Debtors’ proposed Plan contemplates that holders of the Company’s equity securities will receive no recovery of value from their investment. The Monthly Operating Report is limited in scope, covers a limited time period, and has been prepared solely for the purpose of complying with the reporting requirements applicable in the Chapter 11 Cases. The Monthly Operating Report was not audited or reviewed by independent accountants, is in a format prescribed by applicable bankruptcy laws and regulations, and is subject to future adjustment and reconciliation. Therefore, the Monthly Operating Report does not necessarily contain all information required in filings pursuant to the Exchange Act, or may present such information differently from such requirements. There can be no assurance that, from the perspective of an investor or potential investor in the Debtors’ securities, the Monthly Operating Report is complete. The Monthly Operating Report also contains information for periods which are shorter or otherwise different from those required in the Company’s reports pursuant to the Exchange Act, and such information might not be indicative of the Company’s financial condition or operating results for the period that would be reflected in the Company’s financial statements or in its reports pursuant to the Exchange Act. Results set forth in the Monthly Operating Report should not be viewed as indicative of future results.

Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K (this “Current Report”) contains various forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) which are subject to the “safe harbor” created by those sections. Forward-looking statements are based on our management's beliefs and assumptions and on information currently available to our management. All statements other than statements of historical facts are “forward-looking statements” for purposes of these provisions. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “could,” “would,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “project,” “predict,” “potential,” and similar expressions intended to identify forward-looking statements. Forward-looking statements include, but are not limited to, the Consent Solicitation, the Proposed Amendments and the Chapter 11 Cases. Forward-looking statements are subject to risks, uncertainties and other important factors that could cause actual results and the timing of certain events to differ materially from future results expressed or implied by such forward-looking statements. Factors include, among others, risks attendant to the bankruptcy process, including the Company's ability to obtain court approval from the Court with respect to motions or other requests made to the Court throughout the course of Chapter 11; the effects of Chapter 11, including increased legal and other professional costs necessary to execute the Company's restructuring process, on the Company's liquidity (including the availability of operating capital during the pendency of Chapter 11); the effects of Chapter 11 on the interests of various constituents and financial stakeholders; the length of time that the Company will operate under Chapter 11 protection and the continued availability of operating capital during the pendency of Chapter 11; employee attrition and the Company's ability to retain senior management and other key personnel due to the distractions and uncertainties; and other factors discussed in the Company's Annual Report on Form 10-K and subsequent quarterly reports on Form 10-Q filed with the SEC and other factors, as described in the Company's filings with the Securities and Exchange Commission, including the detailed factors discussed under the heading "Risk Factors" in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2024, as supplemented in the Company's Quarterly Report on Form 10-Q for the fiscal quarters ended June 30, 2025 and September 30, 2025. Furthermore, such forward-looking statements speak only as of the date of this release. Except as required by law, we undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements. Risks or uncertainties (i) that are not currently known to us, (ii) that we currently deem to be immaterial, or (iii) that could apply to any company, could also materially adversely affect our business, financial condition, or future results. Additional information concerning certain factors is contained in the Company's Securities and Exchange Commission filings, including but not limited to the Company's Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K.
