Amendment Description This Amendment No. 1 on Form 10-K/A (this “Amendment”) amends our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, that was filed with the Securities and Exchange Commission (the “SEC”) on March 3, 2025 (the “Form 10-K”). We are filing this Amendment to provide the information required by Part III of Form 10-K previously omitted from the Form 10-K in accordance with General Instruction G.(3) to Form 10-K. Accordingly, Items 10, 11, 12, 13 and 14 of Part III of the Form 10-K are replaced in their entirety with the information provided herein. We are filing this Form 10-K/A to include Part III information in our Form 10-K because we will not file a definitive proxy statement containing such information within 120 days after the end of the fiscal year covered by the Form 10-K. In addition, this Form 10-K/A deletes the reference on the cover of the Form 10-K to the incorporation by reference of portions of our proxy statement into Part III of the Form 10-K. As previously disclosed, on November 18, 2024, Spirit Airlines, Inc. (“Former Spirit”), and subsequently on November 25, 2024, its subsidiaries (collectively with Former Spirit, the “Debtors”), filed a voluntary petition for relief under chapter 11 of title 11 of the United States Code in the United States Bankruptcy Court of the Southern District of New York. The Debtors filed a pre-arranged chapter 11 plan of reorganization and related disclosure statement (collectively, the “Plan of Reorganization”). On March 12, 2025, the Debtors satisfied the remaining conditions precedent to consummation of the Plan of Reorganization, the Plan of Reorganization became effective in accordance with its terms and the Debtors emerged from Chapter 11. In connection with the satisfaction of the conditions to effectiveness as set forth in the Confirmation Order and in the Plan of Reorganization, Former Spirit completed a corporate reorganization pursuant to which Spirit Aviation Holdings, Inc., a Delaware corporation (the “Company”) became the new parent company of the Debtors, with Former Spirit becoming a wholly owned subsidiary of Spirit and converted from a Delaware corporation to a Delaware limited liability company. The Company is the successor registrant to Former Spirit. This Amendment also amends Item 15 of Part IV of the Form 10-K solely to include as exhibits the new certifications required by Rule 13a-14(a) under the Securities Exchange Act of 1934, as amended. Because no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. We are not including the certifications under Section 906 of the Sarbanes-Oxley Act of 2002 as no financial statements are being filed with this Amendment. Except as expressly stated, this Amendment does not reflect events occurring after the filing of the Form 10-K or modify or update in any way any of the other items or disclosures contained in the Form 10-K, including, without limitation, the consolidated financial statements and the related footnotes. Accordingly, this Amendment should be read in conjunction with the Form 10-K and the Company’s other filings with the SEC subsequent to the filing of the Form 10-K.
