On the Emergence Date, the Company entered into an Amended and Restated Credit and Guaranty Agreement with the lenders under its former revolving credit facility due in 2026. This agreement modified certain terms and conditions of the existing facility, resulting in a new revolving credit facility of up to $300.0 million (the “Exit Revolving Credit Facility”). Concurrently, Spirit Airlines repaid in full the outstanding balance of $300.0 million under the former revolving credit facility due in 2026.

The Exit Revolving Credit Facility is comprised of (i) commitments by the Exit RCF Lenders to provide revolving credit loans and letters of credit in an aggregate amount equal to $275.0 million (the “Exit RCF Commitments”) and (ii) an uncommitted incremental revolving credit facility in an aggregate amount up to $25.0 million. The Exit Revolving Credit Facility constitutes Spirit Airlines' senior secured obligations and is guaranteed by each of Spirit Airlines' direct and indirect subsidiaries. In addition, in connection with the Corporate Reorganization, Spirit became a guarantor under the Exit Revolving Credit Agreement. On August 21, 2025, Spirit borrowed the entire available amount of $275.0 million under the Revolving Credit Facility. Borrowings under the Revolving Credit Facility will mature on March 12, 2028. As of September 30, 2025, the amounts drawn under the Exit Revolving Credit Facility are included within liabilities subject to compromise on the Company's condensed consolidated balance sheets.

The Exit Revolving Credit Facility is secured by first-priority and second-priority security interests and liens on certain of Spirit Airlines' and its subsidiaries’ assets, including, among other things, (i) certain take-off and landing rights at LaGuardia Airport, (ii) certain eligible aircraft spare parts and ground support equipment and (iii) certain aircraft, spare engines and flight simulators. The revolving loans borrowed under the Exit Revolving Credit Facility will bear interest at a variable rate per

The Exit Revolving Credit Facility contains customary covenants that, among other things, restrict Spirit Airlines' ability and the ability of its subsidiaries to, among other things, make restricted payments, incur additional indebtedness, create certain liens on the collateral, sell or otherwise dispose of the collateral, engage in certain transactions with affiliates and consolidate, merge, sell or otherwise dispose of all or substantially all of Spirit Airlines' and its subsidiaries’ assets. The Exit Revolving Credit Facility also requires the Company to, among other things, maintain (i) so long as any loans or letters of credit are outstanding under the Exit Revolving Credit Facility, unrestricted cash, cash equivalents, short-term investment securities and unused commitments available under all revolving credit facilities (including the Exit Revolving Credit Facility) aggregating not less than $500.0 million, of which no more than $300.0 million may be derived from unused commitments under the Exit Revolving Credit Facility, (ii) a minimum ratio of the borrowing base of the collateral under the Exit Revolving Credit Facility to outstanding obligations under the Exit Revolving Credit Facility of not less than 1.0 to 1.0 (if the Company does not meet the minimum collateral coverage ratio, it must either provide additional collateral to secure its obligations under the Exit Revolving Credit Facility or repay the loans thereunder by an amount necessary to maintain compliance with the collateral coverage ratio), and (iii) the pledged take-off and landing rights of the Company at LaGuardia Airport, a specified number of spare engines and the Company's spare parts (subject to certain exceptions) in the collateral under the Exit Revolving Credit Facility so long as any loans or letters of credit are outstanding under the Existing Revolving Credit Facility.

In connection with the Company's 2025 Chapter 11 Cases, the Exit Revolving Credit Facility has been reclassified to liabilities subject to compromise in the Company's condensed consolidated balance sheet as of September 30, 2025. As of the Petition Date, the Company ceased making principal and interest payments, and ceased accruing interest expense in relation to long-term debt reclassified as liabilities subject to compromise. However, had interest continued to accrue on this obligation under its original terms, the additional interest expense for the three months ended September 30, 2025 would have been $1.9 million for the Exit Revolving Credit Facilities.

On the Effective Date, certain subsidiaries of Spirit Airlines (the “Co-Issuers”) issued $840.0 million in aggregate principal amount of PIK toggle senior secured notes due 2030 (the “2030 Notes" or the “Exit Secured Notes”). The 2030 Notes were issued in a private offering to “qualified institutional buyers” (as defined in Rule 144A under the Securities Act) and to institutional “accredited investors” (as defined in Regulation D of the Securities Act) and outside the United States to non-U.S. persons pursuant to Regulation S. The 2030 Notes are the Co-Issuers’ senior secured obligations and are guaranteed on a senior secured basis by Spirit Airlines and each of its direct and indirect subsidiaries existing on the Effective Date or subsequently acquired and/or formed subsidiaries. In addition, in connection with the Corporate Reorganization, Spirit became a guarantor of the 2030 Notes. The 2030 Notes are secured by second-priority liens on certain Exit Revolving Credit Facility priority collateral (including the collateral under the Exit Revolving Credit Facility described in Note 16 above), and a first-priority lien on all other collateral. The 2030 Notes will mature on March 12, 2030, subject to earlier repurchase or redemption in accordance with the terms of the Indenture (as defined below). The 2030 Notes bear interest, at the option of Spirit Airlines, (i) at 12.00% per annum, of which 8.00% per annum shall be payable in cash and 4.00% per annum shall be payable in-kind or (ii) at 11.00% per annum payable in cash, in each case, in arrears on a quarterly basis. Interest is calculated on the basis of a 360-day year composed of twelve 30-day months.

At any time after March 12, 2027 but on or prior to March 12, 2028, Spirit Airlines may redeem the 2030 Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the 2030 Notes redeemed, plus accrued and unpaid interest to the redemption date, plus a 6.0% premium. Thereafter, Spirit Airlines may redeem the 2030 Notes in whole or in part, at par, plus accrued and unpaid interest to the redemption date.

after the consummation of certain transactions involving acquisitions by a publicly traded airline, the Co-Issuers may redeem the 2030 Notes at their option, in whole, at a redemption price equal to 100% of the principal amount of the 2030 Notes redeemed, plus accrued and unpaid interest to the redemption date, plus an amount equal to the lesser of (A) a 4.0% premium and (B) the then-applicable redemption premium.

The 2030 Notes and guarantees were issued pursuant to an indenture by and among Spirit Airlines, the Co-Issuers, the subsidiary guarantors and Wilmington Trust, National Association, as trustee (the “Trustee”) and collateral custodian, referred to herein as the Indenture. The Indenture contains customary covenants that, among other things, restrict Spirit Airlines' ability and the ability of its subsidiaries to, among other things, make restricted payments, incur additional indebtedness, create certain liens on the collateral, sell or otherwise dispose of the collateral, engage in certain transactions with affiliates and consolidate, merge, sell or otherwise dispose of all or substantially all of Spirit Airlines' and its subsidiaries’ assets. In addition, the Indenture requires that Spirit Airlines maintain unrestricted cash, cash equivalents, short-term investment securities and unused commitments available under all revolving credit facilities (including the Exit Revolving Credit Facility) aggregating not less than $450.0 million, of which no more than $300.0 million may be derived from unused commitments under the Exit Revolving Credit Facility.

In connection with the Company's 2025 Chapter 11 Cases, the Exit Secured Notes have been reclassified to liabilities subject to compromise in the Company's condensed consolidated balance sheet as of September 30, 2025. As of the Petition Date, the Company ceased making principal and interest payments, and ceased accruing interest expense in relation to long-term debt reclassified as liabilities subject to compromise. However, had interest continued to accrue on this obligation under its original terms, the additional interest expense for the three months ended September 30, 2025 would have been $26.1 million for the exit secured notes.

On March 31, 2025, the Company completed a private offering of Class B(R) Pass Through Certificates, Series 2025-1B(R) (the “Class B(R) Certificates”), in the aggregate face amount of $215 million, the proceeds of which were used to acquire new equipment notes to be issued by the Company. During the second quarter of 2025, the Company used the proceeds from the issuance to repay $43.0 million outstanding related to its existing “Series B” equipment notes issued under the 2017-1 pass through certificates, pay transaction fees, and for general corporate purposes.

The Class B(R) Certificates will represent an interest in the assets of a pass through trust (the “Class B(R) Trust”), which will hold certain newly issued equipment notes, designated as “Series B(R)” to be issued by the Company (the “Series B(R) Equipment Notes”). The Series B(R) Equipment Notes are secured by 27 Airbus A320 family aircraft originally delivered new to the Company between October 2015 and October 2018.

The Series B(R) Equipment Notes will have an interest rate of 11.00% per annum. The interest on the issued and outstanding Series B(R) Equipment Notes is payable semi-annually, and principal payments on the issued and outstanding Series B(R) Equipment Notes are scheduled for payment in certain years, and interest and principal payments on the Series B(R) Equipment Notes will be distributed to holders of the Class B(R) Certificates on each April 1 and October 1, commencing October 1, 2025, and the final distribution of the outstanding principal amount of the Series B(R) Equipment Notes to holders of the Class B(R) Certificates is expected on February 15, 2030. The Class B(R) Certificates will rank junior to the outstanding pass through certificates that were previously issued under each of the Spirit Airlines Series 2015-1 (Class A) and Series 2017-1 (Class AA and Class A) pass through certificates.

On December 23, 2024, in connection with the 2024 Bankruptcy, the Company entered into a Superpriority Secured Debtor-In-Possession Term Loan Credit and Note Purchase Agreement, (the “2024 Bankruptcy DIP Credit Agreement”), with Wilmington Savings Fund Society, FSB, as administrative agent and collateral agent (the “Agent”) and the creditors from time to time party thereto (collectively, the “2024 Bankruptcy DIP Creditors”).

As of September 30, 2025, the 2024 Bankruptcy DIP Facility was fully repaid and terminated in connection with the Company’s emergence from the 2024 Bankruptcy. As of December 31, 2024, the outstanding 2024 Bankruptcy DIP term loan was included in current maturities of long-term debt, net of unamortized discounts, and finance leases on the Company’s condensed consolidated balance sheets.
