The delisting became effective ten days after the Form 25 was filed.

Explanatory Note

As previously disclosed, on August 29, 2025, Spirit Aviation Holdings, Inc. (the “Company”) and certain of its controlled affiliates (such affiliates, together with the Company, the “Debtors”) filed voluntary petitions (the “Chapter 11 Cases”) in the U.S. Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”) seeking relief under chapter 11 of title 11 of the U.S. Code (the “Bankruptcy Code”). The Chapter 11 Cases are being jointly administered under Case No. 25-11897 (SHL). Each Debtor continues to operate its business as a “debtor-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and the orders of the Bankruptcy Court.

Item 1.01. Entry into a Material Definitive Agreement

DIP Credit Agreement

In connection with the Chapter 11 Cases, on October 31, 2025, the Bankruptcy Court entered a final order (the “Final DIP Order”) approving Spirit Airlines, LLC, as borrower (the “DIP Borrower”), and certain subsidiaries of the Company from time to time party thereto as guarantors, entering into that certain Superpriority Priming Debtor-in-Possession Credit Agreement (the “DIP Credit Agreement”), dated October 14, 2025, with the lenders from time to time party thereto (the “DIP Lenders”) and Wilmington Trust, National Association, as administrative agent and collateral agent. In connection with entry of the Final DIP Order, the Bankruptcy Court approved certain amendments to the terms by which holders of Prepetition Notes were eligible to receive Roll-Up Loans, including reducing the maximum amount of Roll-Up Loans eligible to be exchanged in connection with the subsequent fundings of New Money Loans under the DIP Credit Agreement..

Pursuant to the DIP Credit Agreement, the DIP Lenders have agreed, upon the terms and conditions set forth therein, to make available to the Company up to $475,000,000 in aggregate principal amount of term loans (the “DIP Facility”). Under the DIP Facility, (i) $200,000,00 in new money term loans (the “Initial New Money DIP Loans”) has been funded under the Interim and Final DIP Orders and (ii) subject to the terms and conditions set forth in the Final DIP Order and the DIP Credit Agreement, up to $275,000,000 in additional new money term loans (the “Additional New Money DIP Loans”; and together with the Initial New Money DIP Loans, the “New Money DIP Loans”) will be made available on certain subsequent dates, including up to $75,000,000 on November 7, 2025, $100,000,000 on December 13, 2025, and $100,000,000 on a subsequent date to be determined as set forth in the Final DIP Order and the DIP Credit Agreement. DIP Lenders that provide New Money DIP Loans shall be entitled to “roll up” a portion of their outstanding PIK Toggle Senior Secured Notes due 2030 (the “Prepetition Notes”) in amounts, and on the terms and conditions, set forth in the Final DIP Order and the DIP Credit Agreement (the “Roll-Up Loans”). New Money Loans will bear interest at a rate equal to, at the Debtors’ option, (i) the Base Rate (subject to a 4% floor) plus 7% per annum or (ii) Term SOFR (subject to a 3% floor) plus 8% per annum. Roll-Up Loans will not bear interest; provided that if the Prepetition Notes and/or the separate tranche of Roll-Up Loans attributable to subsequent borrowings are determined to be oversecured under section 506(b) of the Bankruptcy Code, interest will accrue on the Roll-Up Loans retroactive to the applicable borrowing date in the manner described in the DIP Credit Agreement. The scheduled maturity date of the DIP Facility is July 14, 2026.

The foregoing description of the DIP Credit Agreement and the DIP Facility does not purport to be complete and is qualified in its entirety by reference to the full text of the DIP Credit Agreement and the Final DIP Order, which are incorporated herein by reference.

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, statements regarding the Company’s expectations with respect to operating in the normal course, statements regarding the Company's proposed transformation plan, the Chapter 11 process. 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; objections to the Company’s restructuring process or other pleadings filed that could protract Chapter 11; risks associated with Company proposed transformation plan; risks associated with third-party motions in Chapter 11; Court rulings in the Chapter 11 and the outcome of Chapter 11 in general; employee attrition and the Company’s ability to retain senior management and other key personnel due to the distractions and uncertainties; risks associated with the trading of Company common stock in over-the-counter markets, the impact of litigation and regulatory proceedings; 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 March 31, 2025 and June 30, 2025. Furthermore, such forward-looking statements speak only as of the date of this Current Report. 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.

Cautionary Note Regarding the Chapter 11 Case

The Company cautions that trading in the Common Stock during the pendency of the Chapter 11 Case is highly speculative and poses substantial risks. Trading prices for the Common Stock may bear little or no relationship to the actual recovery, if any, by holders of the Common Stock in the Chapter 11 Case. The Company expects that holders of the Common Stock could experience a significant or complete loss on their investment, depending on the outcome of the Chapter 11 Case.
