Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Basis of Presentation Basis of Presentation
The accompanying unaudited condensed consolidated financial statements include the accounts of Spirit Aviation Holdings, Inc. (“Spirit”) and its consolidated subsidiaries. The term "Company" is used to refer to (a) Spirit and its consolidated subsidiaries for periods on or after the Emergence Date (as defined below) and (b) Spirit Airlines, Inc. ("Spirit Airlines") and its consolidated subsidiaries for periods prior to the Emergence Date.

These unaudited condensed consolidated financial statements reflect all normal recurring adjustments that management believes are necessary to fairly present the financial position, results of operations and cash flows of the Company for the respective periods presented. Certain information and footnote disclosures normally included in the audited annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission for Form 10-Q. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited financial statements of the Company and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2024 filed with the Securities and Exchange Commission on March 3, 2025.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect both the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates. In addition, the classifications of certain prior year amounts have been adjusted in the Company's Condensed Consolidated Financial Statements and these Notes to conform to current year classifications.

The interim results reflected in the unaudited condensed consolidated financial statements are not necessarily indicative of the results that may be expected for other interim periods or for the full year. The air transportation business is subject to significant seasonal fluctuations as demand is generally greater in the second and third quarters of each year. The air transportation business is volatile and highly affected by economic cycles and trends.

On November 18, 2024, (the “Petition Date”), Spirit Airlines commenced a voluntary case (the “Chapter 11 Case”) 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”), and, on November 25, 2024, certain of Spirit Airlines' subsidiaries (together with Spirit Airlines, the “Company Parties”) also filed voluntary petitions seeking relief under Chapter 11 of the Bankruptcy Code and joined the Chapter 11 Case (collectively, the “Chapter 11 Cases”). On February 20, 2025, the Bankruptcy Court entered an order (the "Confirmation Order") confirming the First Amended Joint Chapter 11 Plan of Reorganization of Spirit Airlines, Inc. and Its Debtor Affiliates (the “Plan”). On March 12, 2025 (the “Emergence Date” or "Effective Date"), the Company Parties emerged from the Chapter 11 Cases in accordance with the Plan. Refer to Note 3, Emergence from Voluntary Reorganization under Chapter 11, for additional information.

Between the Petition Date and the Emergence Date, the Company Parties operated as debtors-in-possession under the supervision of the Bankruptcy Court. The effect of the Company’s emergence from bankruptcy has been applied to the financial statements as of close of business on March 12, 2025. As used herein, the following terms refer to the Company and its operations:

"Predecessor"The Company, prior to the Emergence Date
"Current Predecessor Period"The Company's operations, January 1, 2025 – March 12, 2025
"Prior Predecessor Quarter"The Company's operations, April 1, 2024 - June 30, 2024
"Successor"The Company, after the Emergence Date
"Successor Period"The Company's operations, March 13, 2025 - June 30, 2025
"Current Successor Quarter"The Company's operations, April 1, 2025 - June 30, 2025

In accordance with ASC 852, with the application of fresh start accounting to the Successor Period, the Company allocated its reorganization value to its individual assets and liabilities based on their estimated fair value in conformity with FASB ASC Topic 820 - Fair Value Measurements and FASB ASC Topic 805 - Business Combinations. Accordingly, the Successor Period's condensed consolidated financial statements after March 12, 2025 are not comparable with the Predecessor's condensed consolidated financial statements as of or prior to that date. The Effective Date fair values of certain of the Successor’s assets and liabilities differ from their recorded values as reflected on the historical balance sheet of the Predecessor.
Refer to Note 3, Emergence from Voluntary Reorganization under Chapter 11 and Note 4, Fresh Start Accounting, for additional information.

All estimates, assumptions, valuations and financial projections related to fresh start accounting, including the fair value adjustments, the enterprise value and equity value projections, are inherently subject to significant uncertainties and the resolution of contingencies beyond the Company's control. Accordingly, no assurances can be provided that the estimates, assumptions, valuations or financial projections will be realized, and actual results could vary materially. For information about the use of estimates relating to fresh start accounting, refer to Note 4, Fresh Start Accounting.

During the Current Predecessor Period, the Predecessor applied ASC 852 in preparing the unaudited financial statements, which requires distinguishing transactions associated with the reorganization separate from activities related to the ongoing operations of the business. Accordingly, pre-petition liabilities that could have been impacted by the Chapter 11 Cases were classified as liabilities subject to compromise. Additionally, certain expenses, realized gains and losses and provisions for losses that were realized or incurred during and directly related to the Chapter 11 Cases, including fresh start valuation adjustments and gains on liabilities subject to compromise were recorded as reorganization items, net in the condensed consolidated statements of operations in the Current Predecessor Period.

Due to the lack of comparability with historical financials, the Company’s unaudited financial statements and related footnotes are presented with a “black line” that separates the Predecessor and Successor periods to emphasize the lack of comparability between amounts presented as of and after March 12, 2025 (the “Fresh Start Reporting Date”) and amounts presented for all prior periods. The Successor’s financial results for future periods following the application of fresh start accounting will be different from historical trends and the differences may be material. Refer to Note 4, Fresh Start Accounting, for additional information.

The Company evaluates events that occur after the balance sheet date, but before the financial statements are issued for potential recognition or disclosure.

Going Concern

On March 12, 2025, the Company emerged from the Chapter 11 Cases in accordance with the Plan. As part of the reorganization, the Company successfully restructured certain of its debt obligations, established new financing arrangements, and issued new equity securities consisting of new common stock and new warrants. However, the Company has continued to be affected by adverse market conditions, including elevated domestic capacity and continued weak demand for domestic leisure travel in the second quarter of 2025, resulting in a challenging pricing environment. As a result, the Company continues to experience challenges and uncertainties in its business operations and expects these trends to continue for at least the remainder of 2025.

The Company has already taken certain measures to address these challenges, including the implementation of network and product enhancements, including its Premium Economy travel option, consummation of sale-leaseback transactions related to certain of its owned spare engines, and other discretionary cost reduction strategies, including the pilot furloughs announced in July 2025. After considering the measures taken, minimum liquidity covenants in the Company’s debt obligations and credit card processing agreement require financial results to improve at a rate faster than what the Company is currently anticipating. As a result, the Company plans to take additional liquidity enhancing measures, which may include the sale or other monetization of certain aircraft and real estate, the sale of excess airport gate capacity, elimination of certain fixed costs and other transactions to raise additional liquidity. The Company is in discussions with various stakeholders related to some of these future initiatives. The Company is also in discussions with representatives of its credit card processor, which has requested additional collateral to renew its credit card processing agreement, which expires on December 31, 2025. The level of collateral required to be posted could result in a material reduction of unrestricted cash. While it is the Company’s goal to execute on these initiatives, there can be no assurance that such initiatives will be successful.

If these initiatives are unsuccessful, management believes it is probable that the Company will be unable to comply with the minimum liquidity covenants under the Company’s debt obligations and credit card processing agreement at some point in the next 12 months, which would result in an event of default (in the case of the Exit Revolving Credit Facility, if there are amounts drawn and outstanding under the Exit Revolving Credit Facility at that time), which could cause the maturity of the Company's debt obligations to be accelerated. Because of the uncertainty of successfully completing the initiatives to comply with the minimum liquidity covenants and of the outcome of discussions with Company stakeholders, management has concluded there is substantial doubt as to the Company’s ability to continue as a going concern within 12 months from the date these financial statements are issued.

The Company’s condensed consolidated financial statements have been prepared assuming that it will continue to operate as a going concern, which contemplates the continuity of operations, realization of assets and liquidation of liabilities in the normal course of business, and does not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from uncertainty related to its ability to continue as a going concern.

Reorganization Items [Abstract]  
Emergence from Voluntary Reorganization under Chapter 11 Emergence from Voluntary Reorganization under Chapter 11
On the Petition Date, Spirit Airlines commenced the Chapter 11 Case under the Bankruptcy Code in the Bankruptcy Court, and, on November 25, 2024, certain of Spirit Airlines' subsidiaries also filed voluntary petitions seeking relief under Chapter 11 of the Bankruptcy Code and joined the Chapter 11 Cases. On February 20, 2025, the Bankruptcy Court entered the Confirmation Order confirming the Plan. On the Emergence Date, the Company Parties emerged from the Chapter 11 Cases in accordance with the Plan. From the Petition Date to the Emergence Date, the Company Parties operated their businesses as debtors-in-possession under the jurisdiction of the Bankruptcy Court in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.

Plan of Reorganization

On the Emergence Date, all conditions precedent to the effectiveness of the Plan were either satisfied or waived, and the Company Parties emerged from the Chapter 11 Cases. In accordance with the Plan and effective as of the Emergence Date:

Cancellation of Senior Secured Notes and Convertible Notes. The then-outstanding Senior Secured Notes (Class 4 Claims) and Convertible Notes (Class 5 Claims) were canceled and terminated. Refer to Note 15, Debt and Other Obligations, for additional information.

Exit Secured Notes. Certain subsidiaries of Spirit issued $840.0 million of senior secured notes due 2030 (the “Exit Secured Notes”), at an interest rate of (x) 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, (y) if elected by the Company in advance of each quarterly interest period, at 11.00% per annum payable in cash, to certain creditors in the Chapter 11 Cases. Refer to Note 15, Debt and Other Obligations, for additional information.

Exit Revolving Credit Facility. Spirit and certain of its subsidiaries entered into Amended and Restated Credit and Guaranty Agreement with the lenders of the revolving credit facility due in 2026 (“Exit RCF” or "Exit Revolving Credit Facility") that provides revolving credit loans and letters of credit in an aggregated amount equal to $275.0 million and an uncommitted incremental revolving credit facility up to $25.0 million. The commitment of $275.0 million will be reduced to $250.0 million on September 30, 2026. Concurrently, Spirit Airlines paid the then-
outstanding Revolving Credit Facility of $300.0 million (Class 3 Claims) in full. Refer to Note 15, Debt and Other Obligations, for additional information.

Termination of the Debtor-in-Possession Financing. The $300.0 million senior secured superpriority debtor-in-possession facility (the “DIP Facility”) that the Company Parties previously entered into was fully repaid and subsequently terminated. Refer to Note 15, Debt and Other Obligations, for additional information.

Common Stock and Warrants. Spirit issued 16,067,305 shares of a single class of common stock (the “Common Stock”) and 24,255,256 warrants to purchase shares of Common Stock (the “Warrants”) to certain creditors in the Chapter 11 Cases, as further described in Note 8, Equity, and certain adjustments set forth in the Plan.

Cancellation of Prior Equity Securities. All common stock, unvested equity awards, any outstanding PSP loan warrants and all other equity interests in Spirit Airlines that were outstanding immediately prior to the Emergence Date were terminated and canceled. Refer to Note 8, Equity, for additional information.

Settlement of Claims and Fees. General Administrative Claims, Professional Fee Claims, and fees payable to U.S. Trustee were or will be paid in full.

Unimpaired Claims. Other Secured Claims and Other Priority Claims were paid or will be paid in full in the ordinary course, were reinstated, or otherwise rendered unimpaired. General Unsecured Claims were reinstated or otherwise rendered unimpaired.

Election of Directors. Spirit appointed new members to its board of directors, and the directors of Spirit Airlines stepped down.

Charter and Bylaws. Pursuant to the Plan, Spirit amended and restated its certificate of incorporation (the “Charter”) and bylaws (the “Bylaws”), each of which became effective on the Effective Date.

Holding Company Reorganization. The Company completed a corporate reorganization (the “Corporate Reorganization”) pursuant to which Spirit became the new parent company, with Spirit Airlines becoming a wholly owned subsidiary of Spirit and converting from a Delaware corporation to a Delaware limited liability company. Spirit became the successor issuer to Spirit Airlines for SEC reporting purposes pursuant to Rule 15d-5 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The costs of efforts to restructure the Company’s capital, prior to and during the Chapter 11 Cases, along with all other costs incurred in connection with the Chapter 11 Cases, have been material.

Reorganization Items

Any expenses and losses incurred or realized as of or subsequent to the Petition Date through the Emergence Date and as a direct result of the Chapter 11 Cases are recorded within reorganization (gain) expense on the Company's condensed consolidated statements of operations. For the Current Predecessor Period, the Company recorded $421.5 million of reorganization gain which consisted of the following items (in millions):
Predecessor
Reorganization (Gain) ExpensePeriod from 1/1/25 through 3/12/25
Loss on Equity Rights Offering ("ERO") distribution and backstop issuance$115.8

Reorganization (Gain) Expense, net$(421.5)


Special Charges, Non-Operating

Expenses incurred prior to the Petition date or after the Emergence Date in relation to the Chapter 11 Cases are recorded within special charges, non-operating on the Company's condensed consolidated statements of operations. During the Current Successor Quarter, the Successor Period and the Current Predecessor Period the Company recorded charges of $11.0 million, $12.4 million and $5.5 million, respectively. Charges incurred during the Successor periods primarily related to post-emergence restructuring related expenses, including professional fees, other related costs, and termination and retention expenses. Charges incurred during the Current Predecessor Period primarily consisted of professional and other fees. Refer to Note 7, Special Charges (Credits) for additional information.

Fresh Start Accounting

On the Emergence Date, the Company qualified for and adopted fresh start accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic No. 852 – Reorganizations (ASC 852), which specifies the accounting and financial reporting requirements for entities reorganizing through Chapter 11 bankruptcy proceedings. The application of fresh start accounting resulted in a new basis of accounting and the Company becoming a new entity for financial reporting purposes. As a result of the implementation of the Plan and the application of fresh start accounting, these unaudited condensed consolidated financial statements after the Emergence Date are not comparable to the financial statements before that date and the historical financial statements on or before the Emergence Date are not a reliable indicator of its financial condition and results of operations for any period after the Company’s adoption of fresh start accounting. Refer to Note 4, Fresh Start Accounting for additional information.

NYSE American Listing

In connection with the Company's emergence from bankruptcy and consistent with its contractual obligations, the Company applied to list its common stock for listing on the NYSE American stock exchange. Trading began on April 29, 2025, under the symbol FLYY.
Fresh Start Accounting
Adoption of Fresh Start Accounting

In connection with the emergence from bankruptcy and in accordance with ASC 852, the Company qualified for and adopted fresh start accounting on the Emergence Date because (1) the holders of the then-existing common shares of the Predecessor received less than 50% of the Common Stock shares of the Successor outstanding upon emergence and (2) the reorganization value of the Predecessor’s assets immediately prior to confirmation of the Plan of $8,720 million was less than the total of all post-petition liabilities and allowed claims of $9,819 million.

In accordance with ASC 852, upon adoption of fresh start accounting, the reorganization value derived from the enterprise value as disclosed in the Plan was allocated to the Company’s assets and liabilities based on their fair values in accordance with FASB ASC Topic No. 805 - Business Combinations (ASC 805) and FASB ASC Topic No. 820 - Fair Value Measurements (ASC 820), with limited exceptions (such as deferred taxes). The amount of deferred income taxes recorded due to the fair value adjustments to assets and liabilities was determined in accordance with FASB ASC Topic No. 740 - Income Taxes.

With the application of fresh start accounting, the Company allocated its reorganization value to its individual assets and liabilities based on their estimated fair value. Accordingly, the condensed consolidated financial statements after March 12, 2025 are not comparable with the condensed consolidated financial statements as of or prior to that date. The Effective Date fair values of the Successor’s assets and liabilities differ materially from their recorded values as reflected on the historical balance sheet of the Predecessor.
Reorganization Value

The reorganization value represents the fair value of the Successor’s total assets before considering certain liabilities and is intended to approximate the amount a willing buyer would pay for the Successor’s assets immediately after restructuring. The Plan confirmed by the Bankruptcy Court estimated a range of enterprise values between $6.1 billion and $6.8 billion.

The following table reconciles the enterprise value to the reorganization value of Successor’s assets that has been allocated to the Company’s individual assets as of the Fresh Start Reporting Date (in millions):
Fresh Start Reporting Date
Enterprise Value$6,450 
Plus: Excess cash and cash equivalents508 
Plus: Non-operating assets447 
Plus: Current and other liabilities (excluding debt)1,315 
Reorganization Value$8,720 


Analyses

Management's advisors determined the enterprise and corresponding equity value of the Successor using various valuation methods, including (i) discounted cash flow analysis (“DCF”), (ii) public comparable analysis and (iii) precedent transaction analysis. The use of each approach provides corroboration for the other approaches.

DCF Analysis. The DCF analysis is an enterprise valuation methodology that estimates the value of an asset or business by calculating the present value of expected future cash flows to be generated by that asset or business plus a present value of the estimated terminal value of that asset or business. Management's advisor’s DCF analysis used estimated debt-free, after-tax free cash flows through 2028. These cash flows were then discounted at a range of estimated weighted average costs of capital (“Discount Rate”) for Spirit. The Discount Rate reflects the estimated blended rate of return that would be expected by debt and equity investors to invest in Spirit's businesses based on a target capital structure. The enterprise value was determined by calculating the present value of Spirit’s unlevered after-tax free cash flows plus an estimate for the value of Spirit beyond the period covered by the projections reviewed known as the terminal value.

Selected Publicly Traded Companies Analysis. The selected publicly traded companies analysis is based on the enterprise values of selected publicly traded companies that have operating and financial characteristics comparable in certain respects to Spirit. For example, such characteristics may include similar industry, size, and scale of operations, operating margins, growth rates, and geographical exposure. Under this methodology, certain financial multiples that measure financial performance and value are calculated for each selected company and then applied to Spirit’s financials to imply an enterprise value for Spirit. Management advisor used, among other measures, enterprise value (defined as market value of equity, plus book value of debt and book value of preferred stock and minority interests, less cash, subject to adjustments for underfunded obligations and other items where appropriate) for each selected company as a multiple of such company’s publicly available consensus projected EBITDAR for fiscal years 2025 and 2026. Although the selected companies were used for comparison purposes, no selected publicly traded company is either identical or directly comparable to Spirit or its businesses. Accordingly, management advisor’s comparison of selected publicly traded companies to Spirit and its businesses, and its analysis of the results of such comparisons, was not purely mathematical, but instead involved considerations and judgments concerning differences in operating and financial characteristics and other factors that could affect the relative values of the selected publicly traded companies and Spirit. The selection of appropriate companies for this analysis is a matter of judgment and subject to limitations due to sample size and the public availability of meaningful market-based information.

Selected Transaction Analysis. The selected transactions analysis is based on the implied enterprise values of companies and assets involved in publicly disclosed merger and acquisition transactions for which the targets had operating and financial characteristics comparable in certain respects to Spirit. Under this methodology, the enterprise value of each such target is determined by an analysis of the consideration paid and the net debt assumed in the merger or acquisition transaction. The enterprise value is then compared to a selected financial metric, in this case, EBITDAR for Spirit, respectively, for fiscal years 2025 and 2026, to determine an enterprise value multiple. In this analysis, the EBITDAR enterprise value multiples were utilized to determine a range of implied enterprise value for Spirit.
The enterprise value and corresponding equity value are dependent upon achieving the future financial results set forth in the Company's valuations, as well as the realization of certain other assumptions. All estimates, assumptions, valuations and financial projections, including the fair value adjustments, the enterprise value and equity value projections, are inherently subject to significant uncertainties and the resolution of contingencies beyond the Company's control. Accordingly, the Company cannot provide assurances that the estimates, assumptions, valuations or financial projections will be realized, and actual results could vary materially.

Valuation Process

The reorganization value was allocated to the Successor's single reporting segment using the discounted cash flow approach. The reorganization value was then allocated to the Successor’s identifiable assets and liabilities using the fair value principle as contemplated in ASC 820. The specific approach, or approaches, used to allocate reorganization value by asset class are noted below.

To determine fair value adjustments as of the Effective Date, the Company engaged third-party valuation specialists to conduct an analysis of the condensed consolidated balance sheets to determine the fair values of each balance. The most significant fair value adjustments were made to property and equipment, operating lease right-of-use assets and operating lease liabilities, assets held-for-sale, airport take-off and landing rights or "slots", and debt as discussed below.

Property and Equipment

The depreciable lives of the Company's assets were not changed as a result of the adoption of fresh start accounting.

Aircraft and Engines. The aircraft and engines were valued as of the emergence date, using a market approach. Multiple third-party valuation resources (including appraisals of specific aircraft/engines) were consulted and relied upon for estimates of recent half-life and maintenance adjusted ranges for all of the aircraft and engines.

Real Property. The fair values of real property locations were estimated using the sales comparison (market) approach and cost approach. As part of the valuation process, information was obtained on the Successor’s current usage, building type, year built, and cost history for properties. In determining the fair value for real property assets, functional and economic obsolescence was considered and taken as an adjustment at the asset level.

Personal Property. The fair values of the Company’s other personal property (non-aircraft/engines) were estimated using either the cost or market approach. For most personal property categories, a cost approach was utilized relying on purchase year, historic costs, and industry/equipment-based inflation factors to determine replacement cost new of the assets. Readily available market transaction data was used and adjusted for current market conditions for asset categories with active secondary markets such as heavy trucks and computer equipment. In both approaches, consideration was made for the effects of physical deterioration as well as functional and economic obsolescence in determining estimates of fair value.

Operating Right-of-Use Assets and Operating Lease Liabilities

The fair value of operating lease liabilities and the related right-of-use assets was evaluated using the income approach, which is measured as the present value of the remaining lease payments, as if the lease were a new lease as of the Fresh Start Reporting Date. When available, the Company uses the rate implicit in the lease to discount lease payments to present value. However, the Company's leases generally do not provide a readily determinable implicit rate. Therefore, the Company estimates the incremental borrowing rate to discount lease payments based on information available at lease commencement. The Successor used publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates. Additionally, each lease was evaluated for off-market terms as of the Fresh Start Accounting Reporting Date, and the related adjustments were recorded to the right of use asset on the Company's condensed consolidated balance sheets.

Airport Take-Off and Landing Rights or Slots

The fair value of the Company’s 22 airport take-off and landing rights (the “Slots”) at the LaGuardia Airport (“LGA”), a slot-controlled airport, was estimated using a market approach or sales-comparison approach. Specifically, the LGA Slots were valued using observable transaction data for historical sales of other airport take-off and landing rights at LGA. The data was reviewed to estimate a fair value price per Slot, which was applied to the Company’s LGA Slots.
Asset Held-for-Sale

Assets held for sale within the Company's condensed consolidated balance sheets, includes 21 aircraft planned for future sales. These aircraft are not being utilized within the operation and are available for immediate sale as of the Fresh Start reporting date and have been valued at the expected net sale prices (fair value less costs to sell) based upon the executed agreement.

Debt

As of the Emergence Date, Spirit had 35 individual debt instruments comprised of Exit Secured Notes, 4 publicly-traded Enhanced Equipment Trust Certificates ("EETCs"), 22 Fixed Aircraft loans, and 3 Payroll Support Program Agreements. The Company used an income approach, where future cash flows are discounted to present value using a discount rate selected by considering benchmark credit spreads and yield to maturities, to arrive at the estimated fair value for each debt instrument mentioned.

Exit Secured Notes. Upon Emergence, the Company issued $840 million of Exit Secured Notes, which began trading on March 18, 2025 at 92.50% of par. The Company used a discounted cash flow approach to determine the fair value of the Exit Secured Notes on the Emergence Date.

Enhanced Equipment Trust Certificates (EETC). The Company used publicly available trading prices as of the Emergence Date, ranging from 87.32% to 92.85% to determine the fair value of the EETCs.

Fixed-rate Aircraft Loans. Spirit has 22 individual Aircraft Loans issued to finance the purchase of specific aircraft. The Company used a discounted cash flow approach to determine the fair value of the Aircraft Loans. Since each of these loans is fully collateralized with first liens on the related aircraft, the Company applied a notching method to its current credit rating and utilized a credit rating of BB in the valuation of these debt instruments. The Company concluded that the fair value of the Aircraft Loans ranged from 95.61% to 99.84% of par, depending on the loan, as of the Fresh Start accounting Reporting Date.

Payroll Support Program ("PSP"). The Payroll Support Program ("PSP"), under the Coronavirus Aid, Relief, and Economic Security (CARES) Act provided payroll support to passenger and cargo air carriers and certain contractors for the continuation of payment of employee wages, salaries, and benefits. The PSP loans were valued using a discounted cash flow approach based on a CCC- rating based on an estimated yield leveraging federal reserve economic data ("FRED") and other observable yields as of the Emergence Date.

Condensed Consolidated Successor Balance Sheet

The adjustments included in the following fresh start condensed consolidated balance sheet as of March 12, 2025 reflect the effects of the transactions contemplated by the Plan and executed by the Successor on the Fresh Start Reporting Date (reflected in the column Reorganization Adjustments), and fair value and other required accounting adjustments resulting from the adoption of fresh start accounting (reflected in the column Fresh Start Adjustments).

Reorganizations [Abstract]  
Fresh Start Accounting Emergence from Voluntary Reorganization under Chapter 11
On the Petition Date, Spirit Airlines commenced the Chapter 11 Case under the Bankruptcy Code in the Bankruptcy Court, and, on November 25, 2024, certain of Spirit Airlines' subsidiaries also filed voluntary petitions seeking relief under Chapter 11 of the Bankruptcy Code and joined the Chapter 11 Cases. On February 20, 2025, the Bankruptcy Court entered the Confirmation Order confirming the Plan. On the Emergence Date, the Company Parties emerged from the Chapter 11 Cases in accordance with the Plan. From the Petition Date to the Emergence Date, the Company Parties operated their businesses as debtors-in-possession under the jurisdiction of the Bankruptcy Court in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.

Plan of Reorganization

On the Emergence Date, all conditions precedent to the effectiveness of the Plan were either satisfied or waived, and the Company Parties emerged from the Chapter 11 Cases. In accordance with the Plan and effective as of the Emergence Date:

Cancellation of Senior Secured Notes and Convertible Notes. The then-outstanding Senior Secured Notes (Class 4 Claims) and Convertible Notes (Class 5 Claims) were canceled and terminated. Refer to Note 15, Debt and Other Obligations, for additional information.

Exit Secured Notes. Certain subsidiaries of Spirit issued $840.0 million of senior secured notes due 2030 (the “Exit Secured Notes”), at an interest rate of (x) 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, (y) if elected by the Company in advance of each quarterly interest period, at 11.00% per annum payable in cash, to certain creditors in the Chapter 11 Cases. Refer to Note 15, Debt and Other Obligations, for additional information.

Exit Revolving Credit Facility. Spirit and certain of its subsidiaries entered into Amended and Restated Credit and Guaranty Agreement with the lenders of the revolving credit facility due in 2026 (“Exit RCF” or "Exit Revolving Credit Facility") that provides revolving credit loans and letters of credit in an aggregated amount equal to $275.0 million and an uncommitted incremental revolving credit facility up to $25.0 million. The commitment of $275.0 million will be reduced to $250.0 million on September 30, 2026. Concurrently, Spirit Airlines paid the then-
outstanding Revolving Credit Facility of $300.0 million (Class 3 Claims) in full. Refer to Note 15, Debt and Other Obligations, for additional information.

Termination of the Debtor-in-Possession Financing. The $300.0 million senior secured superpriority debtor-in-possession facility (the “DIP Facility”) that the Company Parties previously entered into was fully repaid and subsequently terminated. Refer to Note 15, Debt and Other Obligations, for additional information.

Common Stock and Warrants. Spirit issued 16,067,305 shares of a single class of common stock (the “Common Stock”) and 24,255,256 warrants to purchase shares of Common Stock (the “Warrants”) to certain creditors in the Chapter 11 Cases, as further described in Note 8, Equity, and certain adjustments set forth in the Plan.

Cancellation of Prior Equity Securities. All common stock, unvested equity awards, any outstanding PSP loan warrants and all other equity interests in Spirit Airlines that were outstanding immediately prior to the Emergence Date were terminated and canceled. Refer to Note 8, Equity, for additional information.

Settlement of Claims and Fees. General Administrative Claims, Professional Fee Claims, and fees payable to U.S. Trustee were or will be paid in full.

Unimpaired Claims. Other Secured Claims and Other Priority Claims were paid or will be paid in full in the ordinary course, were reinstated, or otherwise rendered unimpaired. General Unsecured Claims were reinstated or otherwise rendered unimpaired.

Election of Directors. Spirit appointed new members to its board of directors, and the directors of Spirit Airlines stepped down.

Charter and Bylaws. Pursuant to the Plan, Spirit amended and restated its certificate of incorporation (the “Charter”) and bylaws (the “Bylaws”), each of which became effective on the Effective Date.

Holding Company Reorganization. The Company completed a corporate reorganization (the “Corporate Reorganization”) pursuant to which Spirit became the new parent company, with Spirit Airlines becoming a wholly owned subsidiary of Spirit and converting from a Delaware corporation to a Delaware limited liability company. Spirit became the successor issuer to Spirit Airlines for SEC reporting purposes pursuant to Rule 15d-5 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The costs of efforts to restructure the Company’s capital, prior to and during the Chapter 11 Cases, along with all other costs incurred in connection with the Chapter 11 Cases, have been material.

Reorganization Items

Any expenses and losses incurred or realized as of or subsequent to the Petition Date through the Emergence Date and as a direct result of the Chapter 11 Cases are recorded within reorganization (gain) expense on the Company's condensed consolidated statements of operations. For the Current Predecessor Period, the Company recorded $421.5 million of reorganization gain which consisted of the following items (in millions):
Predecessor
Reorganization (Gain) ExpensePeriod from 1/1/25 through 3/12/25
Loss on Equity Rights Offering ("ERO") distribution and backstop issuance$115.8

Reorganization (Gain) Expense, net$(421.5)


Special Charges, Non-Operating

Expenses incurred prior to the Petition date or after the Emergence Date in relation to the Chapter 11 Cases are recorded within special charges, non-operating on the Company's condensed consolidated statements of operations. During the Current Successor Quarter, the Successor Period and the Current Predecessor Period the Company recorded charges of $11.0 million, $12.4 million and $5.5 million, respectively. Charges incurred during the Successor periods primarily related to post-emergence restructuring related expenses, including professional fees, other related costs, and termination and retention expenses. Charges incurred during the Current Predecessor Period primarily consisted of professional and other fees. Refer to Note 7, Special Charges (Credits) for additional information.

Fresh Start Accounting

On the Emergence Date, the Company qualified for and adopted fresh start accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic No. 852 – Reorganizations (ASC 852), which specifies the accounting and financial reporting requirements for entities reorganizing through Chapter 11 bankruptcy proceedings. The application of fresh start accounting resulted in a new basis of accounting and the Company becoming a new entity for financial reporting purposes. As a result of the implementation of the Plan and the application of fresh start accounting, these unaudited condensed consolidated financial statements after the Emergence Date are not comparable to the financial statements before that date and the historical financial statements on or before the Emergence Date are not a reliable indicator of its financial condition and results of operations for any period after the Company’s adoption of fresh start accounting. Refer to Note 4, Fresh Start Accounting for additional information.

NYSE American Listing

In connection with the Company's emergence from bankruptcy and consistent with its contractual obligations, the Company applied to list its common stock for listing on the NYSE American stock exchange. Trading began on April 29, 2025, under the symbol FLYY.
Fresh Start Accounting
Adoption of Fresh Start Accounting

In connection with the emergence from bankruptcy and in accordance with ASC 852, the Company qualified for and adopted fresh start accounting on the Emergence Date because (1) the holders of the then-existing common shares of the Predecessor received less than 50% of the Common Stock shares of the Successor outstanding upon emergence and (2) the reorganization value of the Predecessor’s assets immediately prior to confirmation of the Plan of $8,720 million was less than the total of all post-petition liabilities and allowed claims of $9,819 million.

In accordance with ASC 852, upon adoption of fresh start accounting, the reorganization value derived from the enterprise value as disclosed in the Plan was allocated to the Company’s assets and liabilities based on their fair values in accordance with FASB ASC Topic No. 805 - Business Combinations (ASC 805) and FASB ASC Topic No. 820 - Fair Value Measurements (ASC 820), with limited exceptions (such as deferred taxes). The amount of deferred income taxes recorded due to the fair value adjustments to assets and liabilities was determined in accordance with FASB ASC Topic No. 740 - Income Taxes.

With the application of fresh start accounting, the Company allocated its reorganization value to its individual assets and liabilities based on their estimated fair value. Accordingly, the condensed consolidated financial statements after March 12, 2025 are not comparable with the condensed consolidated financial statements as of or prior to that date. The Effective Date fair values of the Successor’s assets and liabilities differ materially from their recorded values as reflected on the historical balance sheet of the Predecessor.
Reorganization Value

The reorganization value represents the fair value of the Successor’s total assets before considering certain liabilities and is intended to approximate the amount a willing buyer would pay for the Successor’s assets immediately after restructuring. The Plan confirmed by the Bankruptcy Court estimated a range of enterprise values between $6.1 billion and $6.8 billion.

The following table reconciles the enterprise value to the reorganization value of Successor’s assets that has been allocated to the Company’s individual assets as of the Fresh Start Reporting Date (in millions):
Fresh Start Reporting Date
Enterprise Value$6,450 
Plus: Excess cash and cash equivalents508 
Plus: Non-operating assets447

Analyses

Management's advisors determined the enterprise and corresponding equity value of the Successor using various valuation methods, including (i) discounted cash flow analysis (“DCF”), (ii) public comparable analysis and (iii) precedent transaction analysis. The use of each approach provides corroboration for the other approaches.

DCF Analysis. The DCF analysis is an enterprise valuation methodology that estimates the value of an asset or business by calculating the present value of expected future cash flows to be generated by that asset or business plus a present value of the estimated terminal value of that asset or business. Management's advisor’s DCF analysis used estimated debt-free, after-tax free cash flows through 2028. These cash flows were then discounted at a range of estimated weighted average costs of capital (“Discount Rate”) for Spirit. The Discount Rate reflects the estimated blended rate of return that would be expected by debt and equity investors to invest in Spirit's businesses based on a target capital structure. The enterprise value was determined by calculating the present value of Spirit’s unlevered after-tax free cash flows plus an estimate for the value of Spirit beyond the period covered by the projections reviewed known as the terminal value.

Selected Publicly Traded Companies Analysis. The selected publicly traded companies analysis is based on the enterprise values of selected publicly traded companies that have operating and financial characteristics comparable in certain respects to Spirit. For example, such characteristics may include similar industry, size, and scale of operations, operating margins, growth rates, and geographical exposure. Under this methodology, certain financial multiples that measure financial performance and value are calculated for each selected company and then applied to Spirit’s financials to imply an enterprise value for Spirit. Management advisor used, among other measures, enterprise value (defined as market value of equity, plus book value of debt and book value of preferred stock and minority interests, less cash, subject to adjustments for underfunded obligations and other items where appropriate) for each selected company as a multiple of such company’s publicly available consensus projected EBITDAR for fiscal years 2025 and 2026. Although the selected companies were used for comparison purposes, no selected publicly traded company is either identical or directly comparable to Spirit or its businesses. Accordingly, management advisor’s comparison of selected publicly traded companies to Spirit and its businesses, and its analysis of the results of such comparisons, was not purely mathematical, but instead involved considerations and judgments concerning differences in operating and financial characteristics and other factors that could affect the relative values of the selected publicly traded companies and Spirit. The selection of appropriate companies for this analysis is a matter of judgment and subject to limitations due to sample size and the public availability of meaningful market-based information.

Selected Transaction Analysis. The selected transactions analysis is based on the implied enterprise values of companies and assets involved in publicly disclosed merger and acquisition transactions for which the targets had operating and financial characteristics comparable in certain respects to Spirit. Under this methodology, the enterprise value of each such target is determined by an analysis of the consideration paid and the net debt assumed in the merger or acquisition transaction. The enterprise value is then compared to a selected financial metric, in this case, EBITDAR for Spirit, respectively, for fiscal years 2025 and 2026, to determine an enterprise value multiple. In this analysis, the EBITDAR enterprise value multiples were utilized to determine a range of implied enterprise value for Spirit.
The enterprise value and corresponding equity value are dependent upon achieving the future financial results set forth in the Company's valuations, as well as the realization of certain other assumptions. All estimates, assumptions, valuations and financial projections, including the fair value adjustments, the enterprise value and equity value projections, are inherently subject to significant uncertainties and the resolution of contingencies beyond the Company's control. Accordingly, the Company cannot provide assurances that the estimates, assumptions, valuations or financial projections will be realized, and actual results could vary materially.

Valuation Process

The reorganization value was allocated to the Successor's single reporting segment using the discounted cash flow approach. The reorganization value was then allocated to the Successor’s identifiable assets and liabilities using the fair value principle as contemplated in ASC 820. The specific approach, or approaches, used to allocate reorganization value by asset class are noted below.

To determine fair value adjustments as of the Effective Date, the Company engaged third-party valuation specialists to conduct an analysis of the condensed consolidated balance sheets to determine the fair values of each balance. The most significant fair value adjustments were made to property and equipment, operating lease right-of-use assets and operating lease liabilities, assets held-for-sale, airport take-off and landing rights or "slots", and debt as discussed below.

Property and Equipment

The depreciable lives of the Company's assets were not changed as a result of the adoption of fresh start accounting.

Aircraft and Engines. The aircraft and engines were valued as of the emergence date, using a market approach. Multiple third-party valuation resources (including appraisals of specific aircraft/engines) were consulted and relied upon for estimates of recent half-life and maintenance adjusted ranges for all of the aircraft and engines.

Real Property. The fair values of real property locations were estimated using the sales comparison (market) approach and cost approach. As part of the valuation process, information was obtained on the Successor’s current usage, building type, year built, and cost history for properties. In determining the fair value for real property assets, functional and economic obsolescence was considered and taken as an adjustment at the asset level.

Personal Property. The fair values of the Company’s other personal property (non-aircraft/engines) were estimated using either the cost or market approach. For most personal property categories, a cost approach was utilized relying on purchase year, historic costs, and industry/equipment-based inflation factors to determine replacement cost new of the assets. Readily available market transaction data was used and adjusted for current market conditions for asset categories with active secondary markets such as heavy trucks and computer equipment. In both approaches, consideration was made for the effects of physical deterioration as well as functional and economic obsolescence in determining estimates of fair value.

Operating Right-of-Use Assets and Operating Lease Liabilities

The fair value of operating lease liabilities and the related right-of-use assets was evaluated using the income approach, which is measured as the present value of the remaining lease payments, as if the lease were a new lease as of the Fresh Start Reporting Date. When available, the Company uses the rate implicit in the lease to discount lease payments to present value. However, the Company's leases generally do not provide a readily determinable implicit rate. Therefore, the Company estimates the incremental borrowing rate to discount lease payments based on information available at lease commencement. The Successor used publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates. Additionally, each lease was evaluated for off-market terms as of the Fresh Start Accounting Reporting Date, and the related adjustments were recorded to the right of use asset on the Company's condensed consolidated balance sheets.

Airport Take-Off and Landing Rights or Slots

The fair value of the Company’s 22 airport take-off and landing rights (the “Slots”) at the LaGuardia Airport (“LGA”), a slot-controlled airport, was estimated using a market approach or sales-comparison approach. Specifically, the LGA Slots were valued using observable transaction data for historical sales of other airport take-off and landing rights at LGA. The data was reviewed to estimate a fair value price per Slot, which was applied to the Company’s LGA Slots.
Asset Held-for-Sale

Assets held for sale within the Company's condensed consolidated balance sheets, includes 21 aircraft planned for future sales. These aircraft are not being utilized within the operation and are available for immediate sale as of the Fresh Start reporting date and have been valued at the expected net sale prices (fair value less costs to sell) based upon the executed agreement.

Debt

As of the Emergence Date, Spirit had 35 individual debt instruments comprised of Exit Secured Notes, 4 publicly-traded Enhanced Equipment Trust Certificates ("EETCs"), 22 Fixed Aircraft loans, and 3 Payroll Support Program Agreements. The Company used an income approach, where future cash flows are discounted to present value using a discount rate selected by considering benchmark credit spreads and yield to maturities, to arrive at the estimated fair value for each debt instrument mentioned.

Exit Secured Notes. Upon Emergence, the Company issued $840 million of Exit Secured Notes, which began trading on March 18, 2025 at 92.50% of par. The Company used a discounted cash flow approach to determine the fair value of the Exit Secured Notes on the Emergence Date.

Enhanced Equipment Trust Certificates (EETC). The Company used publicly available trading prices as of the Emergence Date, ranging from 87.32% to 92.85% to determine the fair value of the EETCs.

Fixed-rate Aircraft Loans. Spirit has 22 individual Aircraft Loans issued to finance the purchase of specific aircraft. The Company used a discounted cash flow approach to determine the fair value of the Aircraft Loans. Since each of these loans is fully collateralized with first liens on the related aircraft, the Company applied a notching method to its current credit rating and utilized a credit rating of BB in the valuation of these debt instruments. The Company concluded that the fair value of the Aircraft Loans ranged from 95.61% to 99.84% of par, depending on the loan, as of the Fresh Start accounting Reporting Date.

Payroll Support Program ("PSP"). The Payroll Support Program ("PSP"), under the Coronavirus Aid, Relief, and Economic Security (CARES) Act provided payroll support to passenger and cargo air carriers and certain contractors for the continuation of payment of employee wages, salaries, and benefits. The PSP loans were valued using a discounted cash flow approach based on a CCC- rating based on an estimated yield leveraging federal reserve economic data ("FRED") and other observable yields as of the Emergence Date.

Revenue from Contract with Customer [Abstract]  
Revenue Revenue
    
Operating revenues are comprised of passenger revenues and other revenues. Passenger revenues are primarily comprised of fares and related ancillary items such as bags, seats and other travel-related fees. Other revenues primarily consist of the marketing component of the sale of loyalty points to the Company's credit card partner and commissions revenue from the sale of various items, such as hotels and rental cars.

Passenger revenues are generally recognized once the related flight departs. Accordingly, the value of tickets and non-fare revenues sold in advance of travel is included under the Company's current liabilities as “air traffic liability,” or “ATL,” until the related air travel is provided. As of June 30, 2025 and December 31, 2024, the Company had ATL balances of $407.5 million and $436.8 million, respectively. Substantially all of the Company's ATL is expected to be recognized within 12 months of the respective balance sheet date.

Loyalty Programs

The Company operates the Spirit Saver$ Club®, which is a subscription-based loyalty program that allows members access to exclusive, extra-low fares, as well as discounted prices on bags and seats, shortcut boarding and security, and exclusive offers on hotels, rental cars and other travel necessities. The Company also operates the Free Spirit loyalty program, which attracts members and partners and builds customer loyalty for the Company by offering a variety of awards, benefits and services. Free Spirit loyalty program members earn and accrue points for dollars spent on Spirit for flights and other non-fare services, as well as services from non-air partners such as retail merchants, hotels or car rental companies. Customers can also earn points based on their spending with the Company's co-branded credit card company with which the Company has an agreement to sell points. The Company's co-branded credit card agreement provides for joint marketing pursuant to which cardholders earn points by making purchases using co-branded cards. Points earned and accrued by Free Spirit loyalty program members can be redeemed for travel awards such as free (other than taxes and government-imposed fees), discounted or upgraded travel. The Company's agreement with the administrator of the Free Spirit affinity credit card program expires on December 31, 2028.
The Company defers the amount of award travel obligations as part of loyalty deferred revenue within ATL on the Company's condensed consolidated balance sheets and recognizes loyalty travel awards in passenger revenues as points are used for travel or expire unused.

Loss (Gain) on Disposal Loss (Gain) on Disposal
During the three months ended June 30, 2025 and the Successor Period, the Company recorded a net gain of $0.3 million within loss (gain) on disposal of assets in the condensed consolidated statements of operations. This net gain included a $2.9 million gain recorded as a result of one aircraft sale leaseback transaction related to a new aircraft delivery completed during the second quarter of 2025. The gain was partially offset by a $1.7 million loss resulting from an adjustment to previously recorded impairment charges recorded in the fourth quarter of 2024, reflecting a change in estimated costs to sell associated with the Company’s aircraft sale and purchase agreement with GAT entered into on October 29, 2024, as well as $0.9 million in losses related to the write-off of obsolete assets and other adjustments.

During the Current Predecessor Period, the Company recorded a loss of $11.7 million within loss (gain) on disposal of assets in the condensed consolidated statements of operations. This loss included an $18.5 million adjustment to previously recorded impairment charges in the fourth quarter of 2024, reflecting a change in estimated costs to sell associated with the Company’s aircraft sale and purchase agreement with GA Telesis, LLC ("GAT") entered into on October 29, 2024, as well as $0.4 million in losses, related to the write-off of obsolete assets and other adjustments. These losses were partially offset by a $6.4 million gain recorded as a result of two aircraft sale leaseback transactions related to new aircraft deliveries completed during the Current Predecessor Period and a $0.9 million net gain true-up recorded related to the sale of A319 airframes and engines sold in 2024.

Cancellation of Prior Equity Securities

In accordance with the Plan, on the Effective Date, all equity securities in Spirit Airlines outstanding prior to the Effective Date, including Spirit Airlines' common stock, par value $0.0001 per share (the “Old Common Stock”), were canceled, released, and extinguished, and of no further force or effect and without any need for a holder of Old Common Stock to take further action with respect thereto. Furthermore, all of Spirit Airlines' equity award agreements under any incentive plan, and the awards granted pursuant thereto, were extinguished, canceled, and discharged and have no further force or effect.

Issuance of Spirit Equity Securities

On the Effective Date, in connection with the Company Parties' emergence from bankruptcy and in reliance on the exemption from the registration requirements of the Securities Act provided by Section 1145 of the Bankruptcy Code, Spirit issued 7,618,664 shares of Common Stock and 5,203,899 Warrants to equitize the $410.0 million of then-outstanding Senior Secured Notes and $385.0 million of then-outstanding Convertible Notes.

In addition, on the Effective Date, in connection with the Company’s emergence from bankruptcy and in reliance on the exemption from registration requirements of the Securities Act provided by Section 4(a)(2) of the Securities Act or Regulation S under the Securities Act, based in part on representations made by these certain parties to the Backstop Commitment Agreement, Spirit issued 678,587 shares of Common Stock and 5,670,853 Warrants to specified parties to the Backstop Commitment Agreement dated November 18, 2024. An aggregate of 3,849,442 of such shares of Common Stock and such Warrants were issued for aggregate consideration of $53,892,188.

On December 30, 2024, the Company launched an equity rights offering (the “ERO”) of equity securities of the reorganized Company in an aggregate amount of $350.0 million at a purchase price of $14.00 per share. The final expiration
date for the Equity Rights Offering occurred on February 20, 2025. On the Effective Date, in connection with the Company Parties' emergence from bankruptcy and in reliance on the exemption from the registration requirements of the Securities Act provided by Section 1145 of the Bankruptcy Code, Spirit closed the ERO, issuing 7,770,054 shares of Common Stock and 13,380,504 Warrants to ERO participants, for aggregate consideration of $296,107,812. Refer to Note 3, Emergence from Voluntary Reorganization under Chapter 11, for additional information.

The Common Stock and the Warrants are described further below under “—Common Stock” and “—Warrants,” respectively.
Registration Rights Agreement

On the Effective Date, holders of the Common Stock who were party to its Backstop Commitment Agreement became party to the Registration Rights Agreement and are entitled to rights with respect to the registration of certain of their shares of Common Stock under the Securities Act.
Warrants

In connection with the Company's emergence from bankruptcy, on the Effective Date, Spirit entered into two warrant agreements with Equiniti Trust Company, LLC as warrant agent (the “Warrant Agreements”) pursuant to which Spirit issued an aggregate of 24,255,256 Warrants for the Common Stock to certain specified investors, consisting of 3,617,385 Warrants issued under a Tranche 1 Warrant Agreement ("the Tranche 1 Warrants") and 20,637,871 Warrants issued under a Tranche 2 Warrant Agreement (the "Tranche 2 Warrants") pursuant to the Plan. Each Warrant entitles the holder to purchase one share of Common Stock for a nominal exercise price of $0.0001 per Warrant. During the six months ended June 30, 2025, 9.8 million Warrants were exercised and converted into shares of the Company's Common Stock.

Duration and Exercise Price. Each Warrant has an initial exercise price equal to $0.0001 per share of Common Stock. The Tranche 1 Warrants were immediately exercisable, and the Tranche 2 Warrants are exercisable at any time after the date on which the Common Stock is first listed on a securities exchange, which occurred on April 29, 2025. All Warrants may be exercised at any time until such Warrants are exercised in full. The exercise price and number of shares issuable upon exercise are subject to appropriate proportional adjustment in the event of certain dividends, subdivisions or combinations of the Company's Common Stock, or similar events affecting the Company's Common Stock and the exercise price.

Exercisability. A holder may not exercise any portion of its Warrants to the extent that the holder, together with its affiliates and any other persons acting as a group together with any such persons, would own more than 9.9% of the number of shares of Common Stock outstanding immediately after exercise (the “Beneficial Ownership Limitation”) calculated in accordance with Section 13(d) of the Exchange Act. Upon not less than sixty-one (61) days advance written notice to the Company at any time or from time to time, a holder in its sole discretion, may exempt itself from the Beneficial Ownership Limitation. However, under any circumstance, a holder may not exercise the Warrant if such exercise would cause such holder’s beneficial ownership (as defined by Section 13(d) of the Exchange Act) of the Common Stock to exceed 19.9% of its total issued and outstanding Common Stock.

Cashless Exercise. The Warrants may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the holder shall be entitled to receive upon such exercise (either in whole or in part) the net number of shares of Common Stock determined according to a formula set forth in the Warrant Agreements.

Fractional Shares. No fractional shares of Common Stock will be issued upon the exercise of the Warrants and no cash will be distributed in lieu of the issuance of such fractional shares. If more than one Warrant is presented for exercise in full at the same time by the same holder, the full number of shares of Common Stock that will be issuable upon the exercise thereof shall be computed on the basis of the aggregate number of shares of Common Stock purchasable on exercise of the Warrants so presented. If any fraction of a share of Common Stock or other security deliverable upon proper exercise of the Warrant (a "Warrant Share") would, except pursuant to the Warrant, be issuable on the exercise of any Warrants (or specified portion thereof), as applicable, such Warrant Share shall be rounded up to the next highest whole number.

Transferability. Subject to applicable laws, a Warrant may be transferred at the option of the holder upon surrender of the Warrant to Spirit together with the appropriate instruments of transfer and funds sufficient to pay any transfer taxes payable upon such transfer.
Trading Market. There is no trading market available for the Warrants on any securities exchange or nationally recognized trading system. Spirit does not intend to list the Warrants on any securities exchange or nationally recognized trading system.

Rights as a Stockholder. Except as otherwise provided in the Warrants or by virtue of such holder’s ownership of shares of Common Stock, the holders of the Warrants do not have the rights or privileges of holders of the Company's Common Stock, including any voting rights, until they exercise their Warrants.

Fundamental Transaction. In the event of a fundamental transaction, as described in the Warrants and generally including any reorganization, recapitalization or reclassification of the shares of Common Stock, the sale, transfer or other disposition of all or substantially all of its properties or assets, the Spirit's consolidation or merger with or into another person, the holders of the Warrants will be entitled to receive upon exercise of the Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Warrants immediately prior to such fundamental transaction.

Rights to Dividends and Distributions on Common Stock. Holders of the Tranche 1 Warrants are entitled to dividends and other distributions on Common Stock that such holder would have received had the Warrants been exercised. Such distributions to holders of Tranche 1 Warrants will be made simultaneously with the distribution to holders of Common Stock. Tranche 2 Warrants are not entitled to dividends and other distributions on Common Stock.

In addition, the Tranche 2 Warrant Agreement provides that the shares of Common Stock issuable upon exercise of Tranche 2 Warrants shall be subject to the limitations on ownership by non-U.S. citizens as set forth in the Charter (as defined below).

Exchange Rights of Holders of Tranche 2 Warrants. Holders of Tranche 2 Warrants may exchange such Tranche 2 Warrants for Tranche 1 Warrants in accordance with the Warrant Agreements.

Accounting Policy. The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480, Distinguishing Liabilities from Equity (ASC 480) and ASC 815, Derivatives and Hedging (ASC 815). The assessment considers whether the warrants (i) are freestanding financial instruments pursuant to ASC 480, (ii) meet the definition of a liability pursuant to ASC 480, and (iii) meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company's own stock and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding. For warrants that meet all criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital, on the condensed consolidated statements of stockholders’ deficit at the time of issuance.

The Company concluded that the Warrant Agreements are classified as equity, recorded at fair value upon issuance within the Company’s condensed consolidated balance sheets. On the Emergence Date, the Warrants were valued based on the derived Successor Equity Value detailed in Note 4, Fresh Start Accounting, at issuance. Equity-classified contracts are initially measured and recorded at fair value; subsequent changes in fair value are not recognized as long as the contract continues to be classified as equity. The Company recorded $441.7 million, net of issuance costs, in additional paid-in-capital ("APIC"), related to the fair value of the warrants issued.

Common Stock
Pursuant to the Plan, Spirit amended and restated its certificate of incorporation (the “Charter”) and bylaws (the “Bylaws”), each of which became effective on the Effective Date.
The Charter authorizes Spirit to issue up to 400,000,000 shares of Common Stock.
Dividend Rights. Subject to the rights of holders of any series of then outstanding preferred stock and the limitations under the Delaware General Corporation Law ("DGCL"), each holder of Common Stock has equal rights of participation in the dividends in cash, stock, or property of Spirit, when, as and if the Board declare such dividends from time to time out of assets or funds legally available.

Voting Rights. Each holder of the Company's Common Stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. The holders of Common Stock exclusively possess all voting
power; provided, however, that as except as otherwise required by law, holders of Common Stock are not entitled to vote on any amendment to the Charter (or on any amendment to a certificate of designations of any series of preferred stock) that alters or changes the powers, preferences, rights or other terms of one or more outstanding series of preferred stock if the holders of such affected series of preferred stock are entitled to vote, either separately or together with the holders of one or more other such series, on such amendment pursuant to the Charter (or pursuant to a certificate of designations of any series of preferred stock) or pursuant to the DGCL. Spirit's stockholders are not entitled to cumulative voting.

Liquidation. Subject to the rights of holders of any series of then outstanding preferred stock, each holder of Common Stock has equal rights to receive the assets and funds of Spirit available for distribution to stockholders in the event of any liquidation, dissolution, or winding up of the affairs of Spirit, whether voluntary or involuntary.

Rights and Preferences. Holders of Common Stock have no preemptive, conversion, subscription or other rights, and there are no redemption or sinking fund provisions applicable to Common Stock. The rights, preferences and privileges of the holders of Common Stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of Spirit's preferred stock that Spirit may designate in the future.

Limited Voting by Foreign Owners. To comply with restrictions imposed by federal law on foreign ownership of U.S. airlines, the Charter restricts voting of shares of its capital stock by non-U.S. citizens. The restrictions imposed by federal law currently require that no more than 25% of Spirit's voting stock be voted, directly or indirectly, by persons who are not U.S. citizens, and that its president and at least two-thirds of the members of the Board and senior management be U.S. citizens. The Charter provides that no shares of its capital stock may be voted by or at the direction of non-U.S. citizens unless such shares are registered on a separate stock record, which it refers to as the foreign stock record. The Charter further provides that no shares of its capital stock will be registered on the foreign stock record if the amount so registered would exceed the foreign ownership restrictions imposed by federal law.

Leases [Abstract]  
Leases Leases
The Company leases aircraft, engines, airport terminals, maintenance and training facilities, aircraft hangars, commercial real estate, and office and computer equipment, among other items. Certain of these leases include provisions for variable lease payments which are based on several factors, including, but not limited to, relative leased square footage, enplaned passengers, and airports’ annual operating budgets. Due to the variable nature of the rates, these leases are not recorded on the Company's condensed consolidated balance sheets as a right-of-use asset and lease liability. Lease terms are generally 4 years to 18 years for aircraft and up to 99 years for other leased equipment and property.
During the six months ended June 30, 2025, the Company took delivery of three aircraft under sale leaseback transactions and one under direct operating lease. In addition, earlier in the third quarter of 2025, the Company completed sale leaseback transactions involving 14 previously owned spare engines.
As of June 30, 2025, the Company had a fleet consisting of 215 A320 family aircraft. As of June 30, 2025, the Company had 148 aircraft financed under operating leases with lease term expirations between 2026 and 2043. In addition, the Company owned 49 aircraft, of which none were unencumbered, as of June 30, 2025. The Company also had 18 aircraft that would have been deemed finance leases resulting in failed sale leaseback transactions. The related finance obligation is recorded within long-term debt in the Company's condensed consolidated balance sheets. Refer to Note 15, Debt and Other Obligations for additional information. The related asset is recorded within flight equipment in the Company's condensed consolidated balance sheets. As of June 30, 2025, the Company also had 5 spare engines financed under operating leases with lease term expiration dates ranging from 2025 to 2033 and owned 32 spare engines, of which none were unencumbered, as of June 30, 2025.

Aircraft rent expense consists of monthly lease rents for aircraft and spare engines under the terms of the Company's aircraft and spare engine lease agreements recognized on a straight-line basis. Supplemental rent, recorded within aircraft rent expense, is primarily made up of probable and estimable return condition obligations and lease return cost adjustments related to lease modifications and aircraft and engines purchased off lease.

Under the terms of the lease agreements, the Company will continue to operate and maintain the aircraft. Payments under the majority of the lease agreements are fixed for the term of the lease. The lease agreements contain standard termination events, including termination upon a breach of the Company's obligations to make rental payments and upon any other material breach of the Company's obligations under the leases, and standard maintenance and return condition provisions. These return provisions are evaluated at inception of the lease and throughout the lease terms and are accounted for as either fixed or variable lease payments (depending on the nature of the lease return condition) when it is probable that such amounts will be incurred. When determining probability and estimated cost of lease return obligations, there are various other factors that need to be considered, such as the contractual terms of the lease, the ability to swap engines or other aircraft components, current condition of the aircraft, the age of the aircraft at lease expiration, utilization of engines and other components, the extent of repairs needed at return, return locations, current configuration of the aircraft and cost of repairs and materials at the time of return. Management assesses the factors listed above and the need to accrue lease return costs throughout the lease as facts and circumstances warrant an assessment. The Company expects lease return costs will increase as individual aircraft lease
agreements approach their respective termination dates and the Company begins to accrue the estimated cost of return conditions for the corresponding aircraft. Upon a termination of the lease due to a breach by the Company, the Company would be liable for standard contractual damages, possibly including damages suffered by the lessor in connection with remarketing the aircraft or while the aircraft is not leased to another party.

As of June 30, 2025, the Company's finance lease obligations primarily related to the lease of office equipment. Payments under these finance lease agreements are generally fixed for terms of five years. Finance lease assets are recorded within property and equipment and the related liabilities are recorded within long-term debt and finance leases in the Company's condensed consolidated balance sheets.
The following table provides details of the Successor's future minimum lease payments under finance lease liabilities and operating lease liabilities recorded on the Company's condensed consolidated balance sheets as of June 30, 2025. The table does not include commitments that are contingent on events or other factors that are currently uncertain or unknown.

Aircraft-Related Commitments and Financing Arrangements

The Company’s contractual purchase commitments consist primarily of aircraft and engine acquisitions through manufacturers and aircraft leasing companies.

As of June 30, 2025, the Company's total firm aircraft orders consisted of 52 A320 family aircraft with Airbus, including A320neos and A321neos, with deliveries expected from 2029 through 2031. As of June 30, 2025, the Company did not have financing commitments in place for the 52 Airbus aircraft on firm order. The contractual purchase amounts for all aircraft orders from Airbus as of June 30, 2025 are included within the purchase commitments below.

During the third quarter of 2021, the Company entered into an Engine Purchase Support Agreement that requires the Company to purchase a certain number of spare engines in order to maintain a contractual ratio of spare engines to aircraft in the fleet. As of June 30, 2025, the Company is committed to purchase 16 PW1100G-JM spare engines, with deliveries through 2031.

As of June 30, 2025, purchase commitments for the Company's aircraft and engine orders, including estimated amounts for contractual price escalations and pre-delivery payments, were expected to be $18.0 million for the remainder of 2025, $12.3 million in 2026, $183.0 million in 2027, $297.8 million in 2028, $1,124.3 million in 2029 and $1,857.8 million in 2030 and beyond.

During the third quarter of 2019, the United States announced its decision to levy tariffs on certain imports from the European Union, including commercial aircraft and related parts. These tariffs include aircraft and other parts that the Company is already contractually obligated to purchase including those reflected above. In June 2021, the United States Trade Representative announced that the United States and European Union had agreed to suspend reciprocal tariffs on large civilian aircraft for up to five years, pending discussions to resolve their trade dispute. This suspension was withdrawn by the United States on April 2, 2025, and aircraft and parts from the European Union were subject to the same tariffs as other imports.
On July 28, 2025, the United States and the European Union agreed on the terms of a new tariff agreement, under which tariffs on large civilian aircraft and components would again be suspended and returned to zero.

The current U.S. Administration continues to negotiate tariffs with various countries which may lead to expanding the scope of tariffs and significantly increasing the rates on goods imported into the United States. In response, foreign governments have imposed, and are expected to impose, retaliatory tariff measures against the United States.

These or additional changes in U.S. or international trade policies, along with continued uncertainty surrounding such policies, could lead to further weakened business conditions for the transportation industry, which may adversely impact the Company's operations through increased supply chain challenges, commodity price volatility and a decline in discretionary spending and consumer confidence, among others. The Company continues to monitor the situation.

In addition to the Airbus Purchase Agreement, as of June 30, 2025, the Company had agreements in place for 36 A320neos and A321neos to be financed through direct leases with a third-party lessor with deliveries scheduled in 2027 and 2028. As of June 30, 2025, aircraft rent commitments for future aircraft deliveries to be financed under direct leases from third-party lessors were expected to be none for the remainder of 2025, none in 2026, approximately $63.5 million in 2027, $162.3 million in 2028, $210.3 million in 2029 and $2,087.3 million in 2030 and beyond.
Interest commitments related to the secured debt financing of 67 aircraft as of June 30, 2025 were $44.1 million for the remainder of 2025, $80.3 million in 2026, $69.0 million in 2027, $50.1 million in 2028, $35.3 million in 2029 and $106.6 million in 2030 and beyond. As of June 30, 2025, interest commitments related to the Company's unsecured term loans were $1.7 million for the remainder of 2025, $3.4 million in 2026, $3.4 million in 2027, $3.4 million in 2028, $3.4 million in 2029, and $3.7 million in 2030 and beyond. As of June 30, 2025, interest commitments related to the Company's Exit Secured Notes were $34.5 million for the remainder of 2025 $70.5 million in 2026, $73.3 million in 2027, $76.3 million in 2028, $79.4 million in 2029, and $24.2 million in 2030 and beyond. For principal commitments related to the Company's debt financing, refer to Note 15, Debt and Other Obligations.
Other Commitments
The Company is contractually obligated to pay the following minimum guaranteed payments for its reservation system and other miscellaneous subscriptions and services as of June 30, 2025: $26.6 million for the remainder of 2025, $40.4 million in 2026, $33.1 million in 2027, $7.1 million in 2028, $1.9 million in 2029 and $3.7 million in 2030 and thereafter. The Company's reservation system contract expires in 2028.
Other Contractual Arrangements
On July 25, 2023, RTX Corporation, the parent company of Pratt & Whitney, announced that it had determined that a rare condition in the powdered metal used to manufacture certain engine parts will require accelerated inspection of the PW 1100G-JM geared turbo fan (“GTF”) fleet, which powers the Company's A320neo family of aircraft. As a result, the Company removed GTF engines from service and grounded some of its A320neo aircraft for inspection requirements.

On June 4, 2025, the Company entered into an agreement (the “Agreement”) with International Aero Engines, LLC ("IAE"), an affiliate of Pratt & Whitney, pursuant to which IAE will provide the Company with a monthly credit, subject to certain conditions, as compensation for each of the Company's aircraft unavailable for operational service due to GTF engine issues from January 1, 2025 through December 31, 2025. The credits are accounted for as vendor consideration in accordance with ASC 705-20 and are recognized as a reduction of the purchase price of the goods or services acquired from IAE during the period, which may include the purchase of maintenance, spare engines and short-term rentals of spare engines, based on an allocation that corresponds to the Company’s progress towards earning the credits.

As of June 30, 2025, Pratt & Whitney issued the Company $72.4 million in credits related to the aircraft on ground ("AOG") days through June 30, 2025. During the three months ended June 30, 2025, the Company recorded $38.1 million of credits as a reduction in the cost basis of assets purchased from IAE within flight equipment and deferred heavy maintenance, net on the Company's condensed consolidated balance sheets and $14.3 million in credits on the Company's condensed consolidated statements of operations within maintenance, materials and repairs and aircraft rent expenses. In addition, during the three months ended June 30, 2025, the Successor Period, and the Current Predecessor Period, the Company recognized lower depreciation and amortization expense of $6.0 million, $7.2 million, and $6.1 million, respectively, related to credits recognized, under the 2024 and 2025 Agreements with IAE, as a reduction of the cost basis of assets purchased from IAE recorded within the Company's condensed consolidated statements of operations.
The difference remaining between the amount of credits Pratt & Whitney issued and the amount the Company has recognized will be recognized in the future as reductions in the cost basis of goods and services purchased from Pratt & Whitney. The temporary removal of GTF engines from service is expected to continue through at least 2026.
 
Litigation and Assessments
The Company is subject to commercial litigation claims and to administrative and regulatory proceedings and reviews that may be asserted or maintained from time to time. The Company believes the ultimate outcome of such lawsuits, proceedings and reviews will not, individually or in the aggregate, have a material adverse effect on its financial position, liquidity or results of operations. In making a determination regarding accruals, using available information, the Company evaluates the likelihood of an unfavorable outcome in legal or regulatory proceedings and assessments to which the Company is a party and records a loss contingency when it is probable a liability has been incurred and the amount of the loss can be reasonably estimated. These subjective determinations are based on the status of such legal or regulatory proceedings, the merits of the Company's defenses, and consultation with legal counsel. Actual outcomes of these legal and regulatory proceedings may materially differ from the Company's current estimates. It is possible that the resolution of one or more of the legal matters currently pending or threatened could result in losses material to the Company's condensed consolidated results of operations, liquidity or financial condition.
Following an audit by the Internal Revenue Service ("IRS") related to the collection of federal excise taxes on optional passenger seat selection charges covering the period of the second quarter of 2018 through the fourth quarter of 2020, on March 31, 2022, the Company was assessed $34.9 million. On July 19, 2022, the assessment was reduced to $27.5 million. The Company believes it has defenses available and has informed the IRS that it is challenging the assessment. The Company believes a loss in this matter is not probable and has not recognized a loss contingency.
Credit Card Processing Arrangements
The Company has agreements with organizations that process credit card transactions arising from the purchase of air travel, baggage charges and other ancillary services by customers. As is standard in the airline industry, the Company's contractual arrangements with credit card processors permit them, under certain circumstances, to retain a holdback or other collateral, when future air travel and other future services are purchased via credit card transactions. The required holdback is the portion of the Company's overall credit card sales that its credit card processors hold to cover refunds to customers if the Company fails to fulfill its flight obligations.
Except as described below, the Company's credit card processors do not require the Company to maintain cash collateral, provided that the Company satisfies certain liquidity and other financial covenants. Failure to meet these covenants would provide the processors with the right to put in place a holdback resulting in a commensurate reduction of unrestricted cash. As of June 30, 2025 and December 31, 2024, the Company's credit card processors were holding back no remittances.
The maximum potential exposure to cash holdbacks by the Company's credit card processors, based upon advance ticket sales and Spirit Saver$ Club® memberships as of June 30, 2025 and December 31, 2024, was $491.6 million and $469.2 million, respectively.
On July 2, 2024, the Company entered into a letter agreement that modified its existing primary credit card processing agreement to, among other things, extend the term until December 31, 2025, including automatic extensions for two successive one-year terms. However, the renewal of the agreement is subject to the right of either party to opt out of any extension term by written notice to the other within a specified period of time prior to the commencement of any extension term. Based on the terms of the agreement, in July 2024, the Company deposited $200.0 million into a deposit account and deposited $50.0 million into a restricted account. The $200.0 million deposited into the deposit account is considered a compensating balance arrangement that does not legally restrict the Company's use of this cash. As such, the balance of the deposit account is included in cash and cash equivalents within the Company's condensed consolidated balance sheets, and the $50.0 million in the restricted account is included in restricted cash within the Company's condensed consolidated balance sheets going forward. As of June 30, 2025 and 2024, the Company was in compliance with the liquidity and other financial covenants in this credit card processing agreement.
Additionally, the Company provided a $25.0 million deposit to a credit card processor recorded within deposits and other current assets in its condensed consolidated balance sheets.

During the Current Predecessor Period, the Company furloughed approximately 200 pilots to align with its projected flight volume for 2025 and recorded $0.9 million in expenses related to these furloughs. These expenses were recorded within salaries, wages and benefits on the Company's condensed consolidated statements of operations. In addition, as part of the Company's ongoing efforts to optimize and enhance efficiencies, it made the decision to eliminate approximately 200 positions from various departments. The Company recorded $1.8 million in expenses related to these efforts during the Current Predecessor Period. These expenses were recorded within salaries, wages and benefits on the Company’s condensed consolidated statements of operations.

Furthermore, to continue our ongoing efforts to optimize and enhance efficiencies, in July 2025, the Company announced that it will downgrade approximately 140 Captains to First Officers and furlough approximately 270 pilots, effective October 1, 2025 and November 1, 2025, respectively to align with its projected flight volume for 2026.

Fair Value Disclosures [Abstract]  
Fair Value Measurements Fair Value Measurements
Under ASC 820, "Fair Value Measurements and Disclosures," disclosures relating to how fair value is determined for assets and liabilities are required, and a hierarchy for which these assets and liabilities must be grouped is established, based on significant levels of inputs, as follows:
Level 1—Quoted prices in active markets for identical assets or liabilities.
Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes several valuation techniques in order to assess the fair value of the Company’s financial assets and liabilities.
Long-Lived Assets Impairment Analysis
The Company records impairment charges on long-lived assets used in operations when events and circumstances indicate that the assets may be impaired, the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets, and the net book value of the assets exceeds their estimated fair value.
The Company has determined that indicators of potential impairment, including negative cash flows, were present as of June 30, 2025. These indicators prompted the Company to perform a recoverability analysis on its assets to assess whether any impairment losses should be recognized. In estimating the undiscounted future cash flows, the Company uses certain assumptions, including, but not limited to, the estimated, undiscounted future cash flows expected to be generated by these assets, estimates of length of service the asset will be used in the Company’s operations and estimated salvage values. The Company assessed whether any impairment of its long-lived assets existed as of June 30, 2025 and has determined that the assets are recoverable.
The Company’s assumptions about future conditions important to its assessment of potential impairment of its long-lived assets are subject to uncertainty, and the Company will continue to monitor these conditions in future periods as new information becomes available and will update its analyses accordingly.
Indefinite-Lived Intangible Assets

With the adoption of fresh start accounting, the Company recorded $83.5 million of indefinite-lived intangible assets within intangible assets on the Company's condensed consolidated balance sheet as of the Fresh Start Reporting Date. The Company's indefinite-lived intangible assets are related to landing and take-off rights and authorizations (Slots) at the LaGuardia Airport (“LGA”).

These indefinite-lived intangible assets are assessed for impairment annually in September, or more frequently if events or circumstances indicate that the fair values of indefinite-lived intangible assets may be lower than their carrying values. As of June 30, 2025, the Company has not identified any such events or circumstances that would indicate the fair value of the LGA Slots is below their carrying value. Indefinite-lived intangible assets are assessed for impairment by initially performing a qualitative assessment. The Company primarily relies on a quantitative approach to assess impairment, using fair value estimates provided annually by an independent third-party specialist. The specialist applies a market approach to determine fair value, which relies on recent slot transaction data, market lease rates, and input from industry participants and regulatory agencies. Slot values are further adjusted based on factors such as time-of-day, peak demand, and qualitative considerations. These valuations reflect market participant assumptions and are used to determine whether it is more likely than not that the fair value of the Slots is less than their carrying amount.
Long-Term Debt
The estimated fair value of the Company's term loan debt agreements and revolving credit facility have been determined to be Level 3, as certain inputs used to determine the fair value of these agreements are unobservable. The Company utilizes a discounted cash flow method to estimate the fair value of the Level 3 long-term debt. The estimated fair value of the Company's Exit Secured Notes and publicly and non-publicly held EETC debt agreements has been determined to be Level 2, as the Company utilizes quoted market prices in markets with low trading volumes to estimate the fair value of its Level 2 long-term debt.
    The carrying amounts and estimated fair values of the Company's long-term debt at June 30, 2025 and December 31, 2024 were as follows (in millions):

Cash and Cash Equivalents

Cash and cash equivalents at June 30, 2025 and December 31, 2024 were comprised of liquid money market funds and cash and are categorized as Level 1 instruments. The Company maintains cash with various high-quality financial institutions.
Restricted Cash

Restricted cash is comprised of cash held in accounts subject to account control agreements or otherwise pledged as collateral against the Company's letters of credit and is categorized as a Level 1 instrument. In addition, as of June 30, 2025, the Company had $48.7 million in standby letters of credit secured by $49.6 million of restricted cash, of which $44.4 million were issued letters of credit. The Company also had $50.0 million of restricted cash held in an account subject to a control agreement under its credit card processing agreement, $46.5 million of restricted cash held in accounts subject to control agreements to be used for the payment of interest and fees on the Exit Secured Notes and $6.0 million in pledged cash pursuant to its corporate credit cards.

Assets Held for Sale
The Company's assets held for sale as of June 30, 2025 primarily consisted of the 21 A320ceo and A321ceo aircraft planned for future sales. Currently, these aircraft are not being utilized within the operation and are available for immediate sale. The assets are measured at the lower of the carrying amount or fair value, less cost to sell and a loss is recognized for any initial adjustment of the asset’s carrying amount to fair value, less cost to sell. Such valuations include estimations of fair values and incremental direct costs to transact a sale. The fair values were determined using Level 3 fair value inputs primarily based on the agreed upon sales price for each aircraft.
    Assets and liabilities measured at gross fair value on a recurring basis are summarized below (in millions):

Debt and Other Obligations Debt and Other Obligations
Exit Revolving Credit Facility

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. As of June 30, 2025, the Exit Revolving Credit Facility was undrawn and had available capacity of $275.0 million. The Company’s uses of the proceeds of the Exit Revolving Credit Facility shall include, among other items, working capital and other general corporate needs of the Company and its subsidiaries.

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 Exit Revolving Credit Facility will mature on March 12, 2028. The revolving loans borrowed under the Exit Revolving Credit Facility will bear interest at a variable rate per annum equal to the Company's choice of (i) Adjusted Term SOFR plus 3.25% per annum or (ii) Alternate Base Rate plus 2.25% per annum. The commitment amount of $275.0 million will be reduced to $250.0 million on September 30, 2026.
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.

Exit Secured Notes

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 15 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.

On or before March 12, 2027, the 2030 Notes are redeemable by the Co-Issuers, in whole or in part, at a redemption price equal to 100.00% of the principal amount of the 2030 Notes redeemed, plus a “make-whole” premium, plus accrued and unpaid interest, if any, to the date of redemption.

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.

Notwithstanding the foregoing, (x) at any time on or prior to the date that is ninety (90) days after the Effective Date, 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 8.0% premium and (y) upon or 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 Corporate Reorganization, Spirit entered into a supplemental indenture, by and among the Co-Issuers, Spirit and the Trustee, to the Indenture pursuant to which Spirit guaranteed the 2030 Notes.

EETC

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.

DIP Credit Agreement and Facility

On December 23, 2024, in connection with the Chapter 11 Cases, the Company entered into a Superpriority Secured Debtor In Possession Term Loan Credit and Note Purchase Agreement, (the “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 “DIP Creditors”).

Under the DIP Credit Agreement, the DIP Creditors provided an aggregate principal amount of $300.0 million (excluding fees of $9.0 million, which were paid in kind in the form of additional principal) in financing in the form of a senior secured debtor-in-possession facility (the “DIP Facility”).

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

Liabilities Subject to Compromise

The Company's 8.00% senior secured notes, convertible notes due 2025 and convertible notes due 2026, as of the Petition Date, had been classified as “Liabilities Subject to Compromise” on the Company's consolidated balance sheets. Upon emergence from bankruptcy, the liabilities subject to compromise of $1.6 billion were canceled and the applicable agreements governing such obligations were terminated. Refer to Note 3, Emergence from Voluntary Reorganization under Chapter 11, for additional information.

Segment Reporting [Abstract]  
Operating Segments and Related Disclosures Operating Segments and Related Disclosures
The Company operates in a single reportable segment that provides air transportation to passengers. The Company’s Chief Operating Decision Maker (“CODM”) regularly evaluates the Company’s condensed consolidated operating income (loss) to make decisions regarding resource allocation and performance assessment. Additionally, significant segment expenses provided to the CODM align with those shown in the condensed consolidated statement of operations.

Income Tax (Benefit) Expense$(4,100)$17,870 
Effective Rate1.57 %19.84 %

The income tax benefit of $4.0 million and $4.1 million for the three months ended June 30, 2025 and for the Successor Period from March 13, 2025 through June 30, 2025, respectively, is based on the Company's annualized effective rate (“AETR”). For the Successor Period, the Company estimates its AETR for continuing operations in recording its interim income tax provision for the various jurisdictions in which it operates. The tax effects of statutory rate changes, significant unusual or infrequently occurring items, and certain changes in the assessment of the realizability of deferred tax assets are excluded from the determination of the Company's estimated AETR, as such, items are recognized as discrete items in the quarter in which they occur.
The income tax expense of $17.9 million for the Predecessor Period was determined based on actual results for the Predecessor Period ended March 12, 2025, including those resulting from fresh start accounting. Any changes to its deferred tax assets and liabilities for the Predecessor Period (whether resulting from Reorganization Adjustments, Fresh Start Adjustments or otherwise) were partially offset with a corresponding adjustment to its valuation allowance.
In the Chapter 11 Cases, the cancellation of debt income (“CODI”) realized upon emergence from bankruptcy is excludable from taxable income, but results in a reduction of tax attributes in accordance with the attribute reduction and ordering rules of Section 108 of the Internal Revenue Code. The amount of the Company's CODI is estimated to be $478.1 million and will be taken completely against, and therefore will reduce, its NOL carryforwards. After taking into account the CODI, the remaining federal NOL carryforward is estimated to be approximately $1.8 billion and all federal NOL carryforwards do not expire. The reductions in NOL carryforwards for the CODI are expected to be fully offset by a corresponding decrease to the Company's valuation allowance as of December 31, 2025. Some states have similar rules for attribute reduction which will result in the reduction of certain of its state NOL carryforwards.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Basis of Accounting These unaudited condensed consolidated financial statements reflect all normal recurring adjustments that management believes are necessary to fairly present the financial position, results of operations and cash flows of the Company for the respective periods presented. Certain information and footnote disclosures normally included in the audited annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission for Form 10-Q. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited financial statements of the Company and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2024 filed with the Securities and Exchange Commission on March 3, 2025.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect both the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates. In addition, the classifications of certain prior year amounts have been adjusted in the Company's Condensed Consolidated Financial Statements and these Notes to conform to current year classifications.

The interim results reflected in the unaudited condensed consolidated financial statements are not necessarily indicative of the results that may be expected for other interim periods or for the full year. The air transportation business is subject to significant seasonal fluctuations as demand is generally greater in the second and third quarters of each year. The air transportation business is volatile and highly affected by economic cycles and trends.

On November 18, 2024, (the “Petition Date”), Spirit Airlines commenced a voluntary case (the “Chapter 11 Case”) 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”), and, on November 25, 2024, certain of Spirit Airlines' subsidiaries (together with Spirit Airlines, the “Company Parties”) also filed voluntary petitions seeking relief under Chapter 11 of the Bankruptcy Code and joined the Chapter 11 Case (collectively, the “Chapter 11 Cases”). On February 20, 2025, the Bankruptcy Court entered an order (the "Confirmation Order") confirming the First Amended Joint Chapter 11 Plan of Reorganization of Spirit Airlines, Inc. and Its Debtor Affiliates (the “Plan”). On March 12, 2025 (the “Emergence Date” or "Effective Date"), the Company Parties emerged from the Chapter 11 Cases in accordance with the Plan. Refer to Note 3, Emergence from Voluntary Reorganization under Chapter 11, for additional information.

Between the Petition Date and the Emergence Date, the Company Parties operated as debtors-in-possession under the supervision of the Bankruptcy Court. The effect of the Company’s emergence from bankruptcy has been applied to the financial statements as of close of business on March 12, 2025. As used herein, the following terms refer to the Company and its operations:

"Predecessor"The Company, prior to the Emergence Date
"Current Predecessor Period"The Company's operations, January 1, 2025 – March 12, 2025
"Prior Predecessor Quarter"The Company's operations, April 1, 2024 - June 30, 2024
"Successor"The Company, after the Emergence Date
"Successor Period"The Company's operations, March 13, 2025 - June 30, 2025
"Current Successor Quarter"The Company's operations, April 1, 2025 - June 30, 2025

In accordance with ASC 852, with the application of fresh start accounting to the Successor Period, the Company allocated its reorganization value to its individual assets and liabilities based on their estimated fair value in conformity with FASB ASC Topic 820 - Fair Value Measurements and FASB ASC Topic 805 - Business Combinations. Accordingly, the Successor Period's condensed consolidated financial statements after March 12, 2025 are not comparable with the Predecessor's condensed consolidated financial statements as of or prior to that date. The Effective Date fair values of certain of the Successor’s assets and liabilities differ from their recorded values as reflected on the historical balance sheet of the Predecessor.
Refer to Note 3, Emergence from Voluntary Reorganization under Chapter 11 and Note 4, Fresh Start Accounting, for additional information.

All estimates, assumptions, valuations and financial projections related to fresh start accounting, including the fair value adjustments, the enterprise value and equity value projections, are inherently subject to significant uncertainties and the resolution of contingencies beyond the Company's control. Accordingly, no assurances can be provided that the estimates, assumptions, valuations or financial projections will be realized, and actual results could vary materially. For information about the use of estimates relating to fresh start accounting, refer to Note 4, Fresh Start Accounting.

During the Current Predecessor Period, the Predecessor applied ASC 852 in preparing the unaudited financial statements, which requires distinguishing transactions associated with the reorganization separate from activities related to the ongoing operations of the business. Accordingly, pre-petition liabilities that could have been impacted by the Chapter 11 Cases were classified as liabilities subject to compromise. Additionally, certain expenses, realized gains and losses and provisions for losses that were realized or incurred during and directly related to the Chapter 11 Cases, including fresh start valuation adjustments and gains on liabilities subject to compromise were recorded as reorganization items, net in the condensed consolidated statements of operations in the Current Predecessor Period.

Due to the lack of comparability with historical financials, the Company’s unaudited financial statements and related footnotes are presented with a “black line” that separates the Predecessor and Successor periods to emphasize the lack of comparability between amounts presented as of and after March 12, 2025 (the “Fresh Start Reporting Date”) and amounts presented for all prior periods. The Successor’s financial results for future periods following the application of fresh start accounting will be different from historical trends and the differences may be material. Refer to Note 4, Fresh Start Accounting, for additional information.
Recently Issued Accounting Pronouncements Not Yet Adopted
In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures, to enhance the transparency and decision usefulness of income tax disclosures. This standard is effective for the Company for the annual period beginning after December 15, 2024, with early adoption permitted. These amendments should be applied on a prospective basis. Retrospective application is permitted. The Company is currently evaluating the potential impact and related disclosure of adopting this new guidance within its Annual Report on Form 10-K for the year ended December 31, 2025 and subsequent annual reports.
In November 2024, the FASB issued ASU No. 2024-03 (“ASU 2024-03”), Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40). Subsequently, the FASB released ASU NO. 2025-01, which revises the effective date. This standard requires disclosure of specific information about costs and expenses and is effective for the Company for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of this new standard.
