1. Summary of Significant Accounting Policies
Basis of Presentation
The Company is an ultra low-cost, low-fare airline headquartered in Denver, Colorado that offers flights throughout the United States and to select international destinations in the Americas, serving approximately 110 airports.
The Company is managed as a single business unit that provides air transportation for passengers and management has concluded there is only one reportable segment. The Company has identified net income (loss) as the primary measurement of the segment’s profit or loss. Please see the Company’s “Condensed Consolidated Statements of Operations” for net income (loss), as well as other significant revenue and expense components of profit or loss, for the three and six months ended June 30, 2025 and 2024. The Company has identified total assets as the primary measurement of the segment’s assets. Please see the Company’s “Condensed Consolidated Balance Sheets” for total assets as of June 30, 2025 and December 31, 2024.
The accompanying condensed consolidated financial statements include the accounts of the Company and reflect all normal recurring adjustments which 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 annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for Form 10-Q. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, which was filed with the SEC on February 18, 2025 (the “2024 Annual Report”).
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 and is volatile and highly affected by economic cycles and trends.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates.
2. Revenue Recognition
As of June 30, 2025 and December 31, 2024, the Company’s air traffic liability balance was $324 million and $303 million, respectively, which includes amounts classified as other long-term liabilities on the Company’s condensed consolidated balance sheets. During the six months ended June 30, 2025, 89 % of the air traffic liability as of December 31, 2024 was recognized as passenger revenue within the Company’s condensed consolidated

statements of operations. Of the air traffic liability balances as of June 30, 2025 and December 31, 2024, $50 million and $56 million, respectively, was related to unearned membership fees.

The Company, through an affiliate, entered into a PDP facility in December 2014 (as amended from time to time, the “PDP Financing Facility”) for the financing of certain aircraft PDPs. The facility consists of separate loans for each PDP aircraft. Interest is paid every 90 days based on the Secured Overnight Financing Rate (“SOFR”) plus a margin for each separate loan. Each separate loan matures upon the earlier of (i) delivery of that aircraft to the Company by Airbus S.A.S. (“Airbus”), (ii) the date one month following the last day of the scheduled delivery month of such aircraft and (iii) if there is a delay in delivery of aircraft, depending on the cause of the delivery delay, up to six months following the last day of the scheduled delivery month of such aircraft. The PDP Financing Facility will be repaid periodically according to the preceding sentence, with the facility maturing in December 2026.
In September 2024, the Company, through an affiliate, entered into a PDP facility (the “Second PDP Financing Facility”) with a lender not otherwise party to the PDP Financing Facility or Third PDP Financing Facility in connection with the financing of PDPs for certain aircraft deliveries not associated with either the PDP Financing Facility or the Third PDP Financing Facility. Interest is paid quarterly based on SOFR plus an applicable margin. Additionally, the Second PDP Financing Facility requires a commitment fee based on the level of the outstanding loan amounts compared to the committed amount. The Second PDP Financing Facility will be repaid when the facility matures in September 2027.
In September 2024, the Company entered into another PDP facility (the “Third PDP Financing Facility”) with a lender not otherwise party to the PDP Financing Facility or Second PDP Financing Facility in connection with the financing of PDPs for certain aircraft deliveries not associated with either the PDP Financing Facility or the Second PDP Financing Facility. The Third PDP Financing Facility requires commitment fees to be paid, on a quarterly basis, on each individual aircraft delivery once PDP funding begins, based on the reference amount for that aircraft at a fixed annual rate of the two-year U.S. Treasury rate plus an applicable margin. The Third PDP Financing Facility consists of separate loans for each PDP aircraft. Each separate loan matures upon the delivery of that aircraft to the Company. The Third PDP Financing Facility will be repaid periodically according to the preceding sentence, with the facility maturing in August 2026.
(b)Represents notes with a commercial bank related to the Company’s headquarters. In June 2024, the Company entered into a $6 million note maturing in June 2031 and then entered into a second agreement in September 2024 with the same lender to fund an additional $6 million note maturing in September 2031, bringing the total indebtedness to $12 million. The Company is required to make regular monthly payments on principal and unpaid interest. Interest on the notes will accrue on the unpaid principal balance at a fixed annual rate of the seven-year U.S. Treasury rate plus an applicable margin. On the maturity date, one final balloon payment will be made to cover all unpaid principal, accrued unpaid interest and any other amounts due.
(c)In September 2024, the Company entered into a revolving line of credit available for general corporate purposes (the “Revolving Loan Facility”). The Revolving Loan Facility was undrawn at closing and provided $205 million of commitments secured by the Company’s loyalty programs and brand-related assets. The Revolving Loan Facility will bear interest at a rate of SOFR plus an applicable margin, payable in quarterly installments, on any outstanding balance as well as a quarterly commitment fee at an applicable margin on the undrawn amounts. The Revolving Loan Facility matures in September 2027.
(d)The Company entered into an agreement with Barclays Bank Delaware (“Barclays”) in 2003, as amended from time to time, which provides for joint marketing, grants certain benefits to co-branded credit cardholders (“Cardholders”) and allows Barclays to market using the Company’s customer database, through 2029. Cardholders earn miles under the FRONTIER Miles program and the Company sells miles at agreed-upon rates to Barclays and earns fees from Barclays for the acquisition, retention and use of the co-branded credit card by Cardholders. In addition, Barclays will pre-purchase miles if the Company so requests and meets certain conditions precedent. The pre-purchased miles facility amount available to the Company is to be reset on January 15 of each calendar year through 2028, based on the aggregate amount of fees payable by Barclays to the Company on a calendar year basis and subject to certain other conditions, up to an aggregate maximum facility amount of $200 million. The Company pays interest on a monthly basis, which is based on a one-month Effective Federal Funds Rate (“EFFR”) plus a margin. Beginning December 2028, the facility is scheduled to be repaid in 12 equal monthly installments.
(e)As a result of the Company’s participation in the payroll support programs offered by the U.S. Department of the Treasury (the “Treasury”), the Company obtained a series of 10-year , low-interest loans from the Treasury (collectively, the “PSP Promissory Notes”) that are due between 2030 and 2031. The PSP Promissory Notes include an annual interest rate of 1.00 % for the first five years and SOFR plus 2.00 % in the final five years , with bi-annual interest payments. The loans can be prepaid at par at any time without incurring a penalty.
In connection with the term loan facility entered into with the Treasury in September 2020, which was repaid in full in February 2022, and the PSP Promissory Notes, the Company issued warrants to purchase 3,117,940 shares of FGHI common stock at a weighted-average price of $6.95 per share. During the six months ended June 30, 2025, 1,244,608 warrants were exercised. The Company settled the exercises through a net share settlement of 248,893 shares of FGHI common stock and cash of less than $1 million. As of June 30, 2025, warrants to purchase 1,873,332 shares of FGHI common stock were outstanding. The remainder of the warrants will expire between September 2025 and June 2026.

As of June 30, 2025, the lease rates for 14 of the engines depended on usage-based metrics which are variable and, as such, these leases were not recorded on the Company’s condensed consolidated balance sheets as operating lease right-of-use assets or as operating lease liabilities.
During the three and six months ended June 30, 2025 and 2024, the Company completed sale-leaseback transactions with third-party lessors for three , seven , six , and twelve new Airbus A320neo family aircraft, respectively. Additionally, during the three and six months ended June 30, 2025 and 2024, the Company completed zero , two , two , and two sale-leaseback transactions with third-party lessors for engines, respectively. All of the leases from the sale-leaseback transactions are accounted for as operating leases. The Company recognized gains on sale-leaseback transactions of $34 million, $90 million, $77 million and $148 million during the three and six months ended June 30, 2025 and 2024, respectively, which are included as a component of other operating expenses within the Company’s condensed consolidated statements of operations.
Aircraft Rent Expense and Maintenance Obligations
During the three and six months ended June 30, 2025 and 2024, aircraft rent expense was $194 million, $355 million, $147 million and $306 million, respectively. Aircraft rent expense includes supplemental rent, which is made up of probable lease return condition obligations. The portion of supplemental rent expense related to probable lease return condition obligations was $15 million, $3 million, $1 million, and $14 million for the three and

six months ended June 30, 2025 and 2024, respectively. As of June 30, 2025 and December 31, 2024, the Company’s total leased aircraft and spare engine return cost liability was $31 million and $49 million, respectively, which are reflected in accounts payable, other current liabilities and other long-term liabilities on the Company’s condensed consolidated balance sheets.
During the six months ended June 30, 2025, the Company extended the term for certain aircraft operating leases that were slated to expire in 2026 and 2027. For the three and six months ended June 30, 2025, the Company recorded no benefit and a benefit of $20 million, respectively, to aircraft rent in the Company’s condensed consolidated statements of operations related to previously accrued lease return costs. During the six months ended June 30, 2024, the Company extended the term for certain aircraft operating leases that were slated to expire between 2025 and 2027. For the three and six months ended June 30, 2024, the Company recorded a benefit of $11 million and $14 million, respectively, to aircraft rent in the Company’s condensed consolidated statements of operations related to previously accrued lease return costs. These costs were variable in nature and associated with the anticipated utilization and condition of the airframes and engines at the original return date. Given the extension of these aircraft operating leases, such variable return costs are no longer probable of occurring.
During the six months ended June 30, 2024, the Company reached an agreement with one of its aircraft lessors which eliminated requirements to pay maintenance reserves held as collateral in advance of the Company’s required performance of major maintenance activities on its aircraft leases. As a result of the agreement, the lessor disbursed back to the Company previously paid aircraft maintenance deposits of approximately $104 million. As a result, the Company no longer has any aircraft maintenance deposits with any of its lessors.
Airport Facilities
The Company’s facility leases are primarily for space at approximately 110 airports, primarily in the United States. These leases are classified as operating leases and reflect the use of airport terminals, ticket counters, office space and maintenance facilities. Generally, this space is leased from government agencies that control the use of the airport. The majority of these leases are short-term in nature and renew on an evergreen basis. For these leases, the contractual term is used as the lease term. As of June 30, 2025, the remaining lease terms vary from 1 month to 14 years. At the majority of the U.S. airports, the lease rates depend on airport operating costs or use of the facilities and are reset at least annually, and because of the variable nature of the rates, these leases are not recorded on the Company’s condensed consolidated balance sheets as right-of-use assets and lease liabilities.
Other Property and Equipment
The Company leases certain other assets such as flight training equipment, building space, and various other equipment. Certain of the Company’s leases for other assets are deemed to contain fixed rental payments and, as such, are classified as operating leases and are recorded on the Company’s condensed consolidated balance sheets as a right-of-use asset and liability. The remaining lease terms range from one month to ten years as of June 30, 2025.

(a) While the schedule presented above reflects the contractual delivery dates as of June 30, 2025, the Company has recently experienced delays in the deliveries of Airbus aircraft which may persist in future periods.
The Company is party to certain aircraft purchase agreements with Airbus (as amended from time to time, the “Airbus Purchase Agreements”) pursuant to which, as of June 30, 2025, the Company had commitments to purchase an aggregate of 27 A320neo and 153 A321neo aircraft, with deliveries expected through 2031 per the latest delivery schedule.
The Airbus Purchase Agreements also provide for, among other things, varying purchase incentives for each aircraft type (e.g., A320neo versus A321neo), which are allocated proportionally by aircraft and engine type over the remaining aircraft to be delivered so that each aircraft’s capitalized cost upon induction would be equal. Therefore, as cash paid for deliveries is greater than the capitalized cost due to the allocation of these purchase incentives, a deferred purchase incentive is recognized, which will ultimately be offset by future deliveries of aircraft with lower cash payments than their associated capitalized cost. As of June 30, 2025 and December 31, 2024, the Company had $100 million and $95 million, respectively, of deferred purchase incentives recognized within other assets on the Company’s condensed consolidated balance sheets.

Litigation and Other Contingencies
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. During 2023, the DOT sent the Company a request for information to assist in its investigation into whether the Company cared for its customers as required by law during Winter Storm Elliott, which caused significant operational disruptions and spanned from December 21, 2022 to January 2, 2023, including providing adequate customer service assistance, prompt flight status notifications, and proper and timely refunds. The Company is fully cooperating with the DOT request.
Following a federal excise tax audit by the Internal Revenue Service covering the first quarter of 2021 to the second quarter of 2023, in December 2024, the Company received a preliminary assessment in the amount of $149 million related to the applicability of federal excise tax to certain optional ancillary products and services. In June 2025, the Company received a revised assessment in the amount of $133 million. The Company established an estimated liability for certain fees subject to the assessment where it believes a loss for this matter is probable and reasonably estimable. The Company is contesting the updated assessment. The Company could be subject to further excise tax assessments.
The Company regularly evaluates the status of such matters to assess whether a loss is probable and reasonably estimable in determining whether an accrual is appropriate. Further, in determining whether disclosure is appropriate, the Company evaluates each matter to assess if there is at least a reasonable possibility that a loss or additional losses may have been incurred and whether an estimate of possible loss or range of loss can be made.
The ultimate outcomes of legal actions are unpredictable and can be subject to significant uncertainties, and it is difficult to determine whether any loss is probable or even possible. Additionally, it is also difficult to estimate the amount of loss and there may be matters for which a loss is probable or reasonably possible but not currently estimable. Thus, actual losses may be in excess of any recorded liability or the range of reasonably possible loss. The Company believes the ultimate outcome of any potential lawsuits, proceedings and reviews will likely not, individually or in the aggregate, have a material adverse effect on its condensed consolidated financial position, liquidity or results of operations and that the Company’s current accruals cover matters where loss is deemed probable and can be reasonably estimated.

Employees
The Company has seven union-represented employee groups that together represented approximately 87 % of all employees as of June 30, 2025. The table below sets forth the Company’s employee groups and status of the collective bargaining agreements as of June 30, 2025:

(a) Subject to standard early opener provisions.
(b) ALPA filed for mediation through the National Mediation Board (the “NMB”) in January 2024, and the parties are meeting regularly as part of the mediation process. Pursuant to the U.S. Railway Labor Act (the “RLA”), the parties continue to be bound by the existing agreements as negotiations continue.
(c) AFA-CWA filed for mediation through the NMB in October 2024, and the parties are meeting monthly as part of the mediation process, with the first meeting held in February 2025. Pursuant to the RLA, the parties continue to be bound by the existing agreements as negotiations continue.
(d) The Company’s collective bargaining agreements with its material specialists, maintenance controllers and aircraft technicians, each represented by IBT, were still amendable as of June 30, 2025. Pursuant to the RLA, the parties continue to be bound by the existing agreements as negotiations continue.
(e) Effective as of July 11, 2025, a new five-year contract with the Company’s aircraft appearance agents was ratified.
The Company is self-insured for health care claims, subject to a stop-loss policy, for eligible participating employees and qualified dependent medical and dental claims, subject to deductibles and limitations. The Company’s liabilities for claims incurred but not reported are determined based on an estimate of the ultimate aggregate liability for claims incurred. The estimate is calculated from actual claim rates and adjusted periodically as necessary. The Company had accrued $7 million and $6 million for health care claims estimated to be incurred but not yet paid, as of June 30, 2025 and December 31, 2024, respectively, which are included as a component of other current liabilities on the Company’s condensed consolidated balance sheets.
General Indemnifications
The Company has various leases with respect to real property as well as various agreements among airlines relating to fuel consortia or fuel farms at airports. Under some of these contracts, the Company is party to joint and several liability regarding environmental damages. Under others, where the Company is a member of an LLC or other entity that contracts directly with the airport operator, liabilities are borne through the fuel consortia structure.
The Company’s aircraft, services, equipment lease and sale and financing agreements typically contain provisions requiring the Company, as the lessee, obligor or recipient of services, to indemnify the other parties to those agreements, including certain of those parties’ related persons, against virtually any liabilities that might arise from the use or operation of the aircraft or such other equipment. The Company believes that its insurance would cover most of its exposure to liabilities and related indemnities associated with the commercial real estate leases and aircraft, services, equipment lease and sale and financing agreements described above.
18
FRONTIER GROUP HOLDINGS, INC.
Notes to Condensed Consolidated Financial Statements (Continued)
(unaudited)
Certain of the Company’s aircraft and other financing transactions include provisions that require payments to preserve an expected economic return to the lenders if that economic return is diminished due to certain changes in law or regulations. In certain of these financing transactions and other agreements, the Company also bears the risk of certain changes in tax laws that would subject payments to non-U.S. entities to withholding taxes.
Certain of these indemnities survive the length of the related financing or lease. The Company cannot reasonably estimate the potential future payments under the indemnities and related provisions described above because it cannot predict (i) when and under what circumstances these provisions may be triggered, and (ii) the amount that would be payable if the provisions were triggered because the amounts would be based on facts and circumstances existing at such time.
9. Earnings (Loss) per Share
Basic and diluted earnings (loss) per share are computed pursuant to the two-class method. Under the two-class method, the Company attributes net income to common stock and other participating rights (including those with vested share-based awards). Basic earnings per share is calculated by taking net income, less earnings allocated to participating rights, divided by the basic weighted-average common stock outstanding. Loss per share is calculated by taking net loss divided by basic weighted-average common stock outstanding as participating rights do not share in losses. In accordance with the two-class method, diluted earnings per share is calculated using the more dilutive impact of the treasury-stock method or from reducing net income for the earnings allocated to participating rights.
The following table sets forth the computation of earnings (loss) per share on a basic and diluted basis pursuant to the two-class method for the periods indicated (in millions, except for share and per share data):
| Three Months Ended June 30, | Six Months Ended June 30, | ||||||||||||||||||||||
| 2025 | 2024 | 2025 | 2024 | ||||||||||||||||||||

| Weighted-average common shares outstanding, diluted | |||||||||||||||||||||||
| Earnings (loss) per share, diluted | $ | ( | $ | $ | ( | $ | |||||||||||||||||
Due to the net loss for each of the three and six months ended June 30, 2025, diluted weighted-average shares outstanding are equal to basic weighted-average shares outstanding because the effect of all equity awards is anti-dilutive. Approximately 5,007,745 and 5,154,621 shares were excluded from the computation of diluted weighted-average shares for the three and six months ended June 30, 2024, respectively, due to anti-dilutive effects.

10. Income Taxes
When a reliable estimate cannot be made, the Company computes the interim income tax provision based on the actual effective tax rate for the year-to-date period by applying the discrete method. The Company has calculated its effective tax rate using the discrete method for the three and six months ended June 30, 2025 and 2024.
The Company accounts for income taxes using the asset and liability method. Deferred income taxes are recognized for the tax consequences of temporary differences between the tax and financial statement reporting basis of assets and liabilities. Quarterly, the Company assesses whether it is more likely than not that sufficient taxable income will be generated to realize deferred income tax assets, and a valuation allowance is recorded when it is more likely than not that some portion, or all, of the Company’s deferred tax assets, will not be realized. The Company considers sources of taxable income from prior period carryback periods, future reversals of existing taxable temporary differences, tax planning strategies and future projected taxable income when assessing the future realization of deferred tax assets.
The Company’s effective tax rate for the three and six months ended June 30, 2025 was an expense of 0 % and 2.7 %, respectively, on pre-tax losses, compared to an expense of 3.1 % and 37.5 %, respectively, on pre-tax income for the three and six months ended June 30, 2024. The effective tax rate for the three and six months ended June 30, 2025 was lower than the statutory rate primarily due to nonrecognition of current period tax benefits due to a valuation allowance recorded for U.S. federal and state net operating losses. The Company’s effective tax rate for the three months ended June 30, 2024 was lower than the statutory rate primarily due to a decrease in the Company’s valuation allowance relating to U.S. federal and state net operating losses. The effective tax rate for the six months ended June 30, 2024 was higher than the statutory rate primarily due to the non-deductibility of certain executive compensation costs and other employee benefits, as well as shortfalls related to the vesting and exercise of the Company’s share-based awards offset by a decrease in the valuation allowance.
In assessing the sources of taxable income and the need for a valuation allowance, the Company considers all available positive and negative evidence, which includes a recent history of cumulative losses. As of June 30, 2025, it was more likely than not that the benefit from a portion of its federal, state and foreign deferred tax assets will not be realized. Accordingly, as of June 30, 2025, the Company had a valuation allowance of $45 million against its deferred tax assets for U.S. federal and state net operating loss carryforwards, which included increases in the Company’s valuation allowance of $14 million and $26 million, respectively, recorded during the three and six months ended June 30, 2025.
11. 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 its financial assets and liabilities.
Cash, Cash Equivalents and Restricted Cash
Cash, cash equivalents and restricted cash are comprised of liquid money market funds, time deposits and cash, and are categorized as Level 1 instruments. The Company maintains cash with various high-quality financial institutions. Cash, cash equivalents and restricted cash are carried at cost, which management believes approximates fair value.
Debt
The estimated fair value of the Company’s debt agreements has been determined to be a Level 3 measurement, 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 debt.
The carrying amounts and estimated fair values of the Company’s debt are as follows (in millions):

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and the related notes included elsewhere in this Quarterly Report on Form 10-Q, as well as Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Part II, Item 8. “Financial Statements and Supplementary Data” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, which was filed with the SEC on February 18, 2025 (the “2024 Annual Report”).
Recent Developments
Macroeconomic Conditions. The Trump Administration is in the process of expanding the scope of tariffs, which has significantly increased the rates on goods imported into the United States. In response, foreign governments have imposed, and are expected to impose, retaliatory 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 our operations through increased supply chain challenges, commodity price volatility and a decline in discretionary spending and consumer confidence, among others. We continue to monitor the situation.
Labor. We are currently in negotiations with the unions which represent our pilots, flight attendants, material specialist and maintenance controllers regarding their next labor contracts. Additionally, a new five-year contract with our aircraft appearance agents became effective as of July 11, 2025. Please refer to “Notes to Condensed Consolidated Financial Statements — 8. Commitments and Contingencies” for additional information.
Legal. During 2024, we received a preliminary assessment in the amount of $149 million related to the applicability of federal excise tax to certain optional ancillary products and services. In June 2025, we received an updated assessment in the amount of $133 million. We established an estimated liability for certain fees subject to the assessment where we believe a loss for this matter is probable and reasonably estimable. We are contesting the updated assessment.
Pratt & Whitney. Since 2022, we have introduced aircraft into our fleet that use the Pratt & Whitney PW1100 Geared Turbo Fan (“GTF”) engine, and we have selected this engine for our planned future deliveries. During 2023, Pratt & Whitney announced the requirement, mandated by the U.S. Federal Aviation Administration, that certain engines be removed for inspection due to a possible condition in the powdered metal used to manufacture certain engine parts. This will require accelerated inspection of the PW1100 GTF engine, which we use for certain of our A320neo family aircraft, and could result in lengthy turnaround times to perform these inspections, including any resulting repairs or other modifications that may be identified. Although our operations have not been materially impacted as of June 30, 2025, this inspection program may have an adverse impact on our operations, particularly when we are required to temporarily take aircraft out of service. We continue to assess the impact on our future capacity plans.
In July 2025, we executed an agreement with Pratt & Whitney to have their GTF engines power 91 Airbus A321neo aircraft as well as establishing 28 additional spare engines to be delivered throughout the orderbook. Please refer to “Notes to Condensed Consolidated Financial Statements — 13. Subsequent Events” for additional information.

Revenues
Total operating revenues for the three months ended June 30, 2025 totaled $929 million, a decrease of 5% compared to the three months ended June 30, 2024. This was primarily due to a 2% moderation in capacity, as measured by ASMs, as part of strategic initiatives to stabilize pricing, and a 2% decrease in revenue per available seat mile (“RASM”) for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The RASM decrease was driven by a 5% higher average stage length supported by 9% fewer departures, which also contributed to the 4% decrease in passenger enplanements, partly offset by the 1.2-point increase in load factor on a higher capacity fleet mix as compared to the corresponding prior year period.
Total operating revenues for the six months ended June 30, 2025 totaled $1,841 million, which is consistent with the six months ended June 30, 2024. This was primarily due to the 1% increase in capacity, as measured by ASMs, offset by a RASM decrease of 1% for the six months ended June 30, 2025, as compared to the six months ended June 30, 2024.
Operating Expenses
Total operating expenses during the three months ended June 30, 2025 increased to $1,004 million, resulting in a cost per available seat mile (“CASM”) of 9.73¢, an increase of 8%, as compared to the three months ended June 30, 2024. Fuel expense for the three months ended June 30, 2025 was $58 million lower than the corresponding prior year period. The 20% decrease in fuel expense for the three months ended June 30, 2025 was primarily driven by the 17% decrease in fuel cost per gallon, as well as the 4% decrease in fuel gallons consumed, as a result of our 2% capacity reduction.
Our non-fuel expenses increased by 17% during the three months ended June 30, 2025, as compared to the corresponding prior year period, driven primarily by increased aircraft rent due to a larger fleet size and higher lease return costs, decreased sale-leaseback transactions, and increased station costs due to station mix and rate inflation, partly offset by decreased operations from fewer passengers and departures. CASM (excluding fuel), a non-GAAP measure, increased 20% to 7.50¢, on a 2% decrease in capacity for the three months ended June 30, 2025, as compared to the corresponding prior year period based on the aforementioned factors.
Total operating expenses during the six months ended June 30, 2025 increased to $1,962 million, resulting in a CASM of 9.68¢, an increase of 5% compared to the six months ended June 30, 2024. Fuel expense for the six months ended June 30, 2025 was $83 million lower than the corresponding prior year period. The 15% decrease in fuel expense for the six months ended June 30, 2025 was primarily driven by the 15% decrease in fuel cost per gallon while consumption held flat.
Our non-fuel expenses increased 16% during the six months ended June 30, 2025, as compared to the corresponding prior year period, driven primarily by a decrease in sale-leaseback transactions, increased station operations due to station mix and rate inflation and increased aircraft rent due to a larger fleet, partly offset by lower
24
lease return costs during the same period. CASM (excluding fuel), a non-GAAP measure, increased 14% to 7.37¢, on a 1% increase in capacity for the six months ended June 30, 2025, as compared to the corresponding prior year based on the aforementioned factors.
Net Income (Loss)
We generated a net loss of $70 million during the three months ended June 30, 2025, compared to net income of $31 million for the three months ended June 30, 2024. There were no non-GAAP adjustments for each of the three months ended June 30, 2025 and 2024.
We generated a net loss of $113 million during the six months ended June 30, 2025, compared to net income of $5 million for the six months ended June 30, 2024. There were no non-GAAP adjustments during the six months ended June 30, 2025. For the six months ended June 30, 2024, our adjusted net income, a non-GAAP measure, was $10 million, due to the $5 million valuation allowance.
For the reconciliation to the corresponding GAAP measures of the aforementioned non-GAAP adjusted measures, see “Results of Operations — Reconciliation of CASM to CASM (excluding fuel), Adjusted CASM (excluding fuel), Adjusted CASM, Adjusted CASM including net interest and CASM including net interest” and “Results of Operations — Reconciliation of Net Income (Loss) to Adjusted Net Income (Loss) and Net Income (Loss) to EBITDA, EBITDAR, Adjusted EBITDA, and Adjusted EBITDAR”.
Liquidity
As of June 30, 2025, our total available liquidity was $766 million, made up of unrestricted cash and cash equivalents, including $205 million of funds available to be drawn under our revolving line of credit available for general corporate purposes (the “Revolving Loan Facility”).

Total operating revenue decreased $44 million, or 5%, during the three months ended June 30, 2025 compared to the three months ended June 30, 2024. Capacity, as measured by ASMs, and RASM each decreased 2%, with the decrease in RASM driven by a 5% higher average stage length supported by 9% fewer departures, which also contributed to the 4% decrease in passenger enplanements, partly offset by the 1.2-point increase in load factor with total revenue per passenger remaining flat, as compared to the corresponding period. Strategic initiatives to stabilize pricing resulted in a moderation of capacity, which was driven by a 13% decrease in average daily aircraft utilization during the three months ended June 30, 2025, as compared to the three months ended June 30, 2024, partly offset by the 12% increase in average aircraft in service.

Aircraft Fuel. Aircraft fuel expense decreased by $58 million, or 20%, during the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The decrease was primarily due to the 17% decrease in fuel cost per gallon, as well as the 4% decrease in fuel gallons consumed, driven by lower capacity.
Salaries, Wages and Benefits. Salaries, wages and benefits expense increased by $10 million, or 4%, during the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The increase was primarily due to higher employee benefit costs as compared to the corresponding prior year period.
Aircraft Rent. Aircraft rent expense increased by $47 million, or 32%, during the three months ended June 30, 2025, as compared to the three months ended June 30, 2024, primarily due to a larger fleet and higher lease return
26
costs in the current period due to aircraft lease extension events and the corresponding benefit that occurred in the comparable three months ended June 30, 2024.
Station Operations. Station operations expense increased by $15 million, or 9%, during the three months ended June 30, 2025, as compared to the three months ended June 30, 2024, primarily due to an increase in station mix and rate inflation, offset by a 4% decrease in passengers and 9% decrease in departures.
Maintenance, Materials and Repairs. Maintenance, materials and repair expense increased by $5 million, or 12%, during the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. This increase was primarily due to the 12% increase in average aircraft in service, which resulted in higher aircraft repairs and materials costs, partially offset by lower engine repair costs.
Sales and Marketing. Sales and marketing expense decreased by $8 million, or 17%, during the three months ended June 30, 2025, as compared to the three months ended June 30, 2024, primarily due to the decrease in third-party distribution channel fees, media advertising and credit card fees as a result of a 5% decrease in revenue. The following table presents our distribution channel mix:

Third-party channels | 30 | % | 28 | % | 2 | pts | |||||||||||
Depreciation and Amortization. Depreciation and amortization expense increased by $3 million, or 17%, during the three months ended June 30, 2025, as compared to the three months ended June 30, 2024, primarily due to an increase in capitalized maintenance depreciation due to our growing fleet.
Other Operating. Other operating resulted in an expense of $41 million during the three months ended June 30, 2025, compared to a net gain of $1 million during the three months ended June 30, 2024. This movement was primarily driven by a decrease in sale-leaseback gains, as a result of three aircraft inductions subject to sale-leaseback transactions in the current period, compared to six aircraft inductions and two engine inductions subject to sale-leaseback transactions in the corresponding prior year period.
Other Income (Expense). Other income decreased by $2 million, or 29%, during the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The decrease was primarily due to increased interest expense and lower interest income from lower balances in interest-bearing cash accounts, driven by higher principal balances on our debt, partially offset by greater capitalized interest.
Income Taxes. Our effective tax rate for the three months ended June 30, 2025 was 0% on a pre-tax loss, compared to an expense of 3.1% on pre-tax income for the three months ended June 30, 2024. The primary difference between the effective tax rate and the federal statutory rate was related to an increase in our valuation allowance relating to federal and state net operating losses.

Aircraft Fuel. Aircraft fuel expense decreased by $83 million, or 15%, during the six months ended June 30, 2025, as compared to the six months ended June 30, 2024. The decrease was primarily due to the 15% decrease in fuel cost per gallon.
Salaries, Wages and Benefits. Salaries, wages and benefits expense increased by $26 million, or 5%, during the six months ended June 30, 2025, as compared to the six months ended June 30, 2024. The increase was due to higher crew costs and higher employee benefit costs, as compared to the corresponding prior year period.
Aircraft Rent. Aircraft rent expense increased by $49 million, or 16%, during the six months ended June 30, 2025, as compared to the six months ended June 30, 2024, primarily due to a larger fleet, partially offset by lower aircraft lease return costs.
Station Operations. Station operations expense increased by $58 million, or 19%, during the six months ended June 30, 2025, as compared to the six months ended June 30, 2024, primarily due to station mix and rate inflation as well as increased airport operations.
Maintenance, Materials and Repairs. Maintenance, materials and repair expense increased by $7 million, or 8%, during the six months ended June 30, 2025, as compared to the six months ended June 30, 2024. This increase
29
was primarily due to the 12% increase in average aircraft in service, which resulted in higher aircraft repair and materials costs, offset by lower engine repair costs.
Sales and Marketing. Sales and marketing expense decreased by $7 million, or 8%, during the six months ended June 30, 2025, as compared to the six months ended June 30, 2024, primarily due to the decrease in distribution channel fees, media advertising and credit card fees.

__________________
(a)Cost per ASM figures may not recalculate due to rounding.
(b)CASM (excluding fuel) and Adjusted CASM (excluding fuel) are included as supplemental disclosures because we believe that excluding aircraft fuel is useful to investors as it provides an additional measure of management’s performance excluding the effects of a significant cost item over which management has limited influence. The price of fuel, over which we have limited control, impacts the comparability of period-to-period financial performance, and excluding the price of fuel allows management an additional tool to understand and analyze our non-fuel costs and core operating performance, and increases comparability with other airlines that also provide a similar metric. CASM (excluding fuel) and Adjusted CASM (excluding fuel) are not determined in accordance with GAAP and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.
(c)For each of the three months ended June 30, 2025 and 2024, there were no non-GAAP pre-tax adjustments.
(d)Adjusted CASM is included as supplemental disclosure because we believe it is a useful metric to properly compare our cost management and performance to other peers, as derivations of Adjusted CASM are well-recognized performance measurements in the airline industry that are frequently used by our management, as well as by investors, securities analysts and other interested parties in comparing the operating performance of companies in the airline industry. Additionally, we believe this metric is useful because it removes certain items that may not be indicative of our base operating performance or future results. Adjusted CASM is not determined in accordance with GAAP, may not be comparable across all carriers and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.
(e)Adjusted CASM including net interest and CASM including net interest are included as supplemental disclosures because we believe they are useful metrics to properly compare our cost management and performance to other peers that may have different capital structures and financing strategies, particularly as it relates to financing primary operating assets such as aircraft and engines. Additionally, we believe these metrics are useful because they remove certain items that may not be indicative of our base operating performance or future results. Adjusted CASM including net interest and CASM including net interest are not determined in accordance with GAAP, may not be comparable across all carriers and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.

__________________
(a)Cost per ASM figures may not recalculate due to rounding.
(b)CASM (excluding fuel) and Adjusted CASM (excluding fuel) are included as supplemental disclosures because we believe that excluding aircraft fuel is useful to investors as it provides an additional measure of management’s performance excluding the effects of a significant cost item over which management has limited influence. The price of fuel, over which we have limited control, impacts the comparability of period-to-period financial performance, and excluding the price of fuel allows management an additional tool to understand and analyze our non-fuel costs and core operating performance, and increases comparability with other airlines that also provide a similar metric. CASM (excluding fuel) and Adjusted CASM (excluding fuel) are not determined in accordance with GAAP and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.
(c)For each of the six months ended June 30, 2025 and 2024, there were no non-GAAP pre-tax adjustments.
(d)Adjusted CASM is included as supplemental disclosure because we believe it is a useful metric to properly compare our cost management and performance to other peers, as derivations of Adjusted CASM are well-recognized performance measurements in the airline industry that are frequently used by our management, as well as by investors, securities analysts and other interested parties in comparing the operating performance of companies in the airline industry. Additionally, we believe this metric is useful because it removes certain items that may not be indicative of our base operating performance or future results. Adjusted CASM is not determined in accordance with GAAP, may not be comparable across all carriers and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.
(e)Adjusted CASM including net interest and CASM including net interest are included as supplemental disclosures because we believe they are useful metrics to properly compare our cost management and performance to other peers that may have different capital structures and financing strategies, particularly as it relates to financing primary operating assets such as aircraft and engines. Additionally, we believe these metrics are useful because they remove certain items that may not be indicative of our base operating performance or future results. Adjusted CASM including net interest and CASM including net interest are not determined in accordance with GAAP, may not be comparable across all carriers and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.

(a)Adjusted net income (loss), EBITDA and adjusted EBITDA are included as supplemental disclosures because we believe they are useful indicators of our operating performance. Derivations of net income (loss) and EBITDA are well-recognized performance measurements in the airline industry that are frequently used by our management, as well as by investors, securities analysts and other interested parties in comparing the operating performance of companies in our industry.
Adjusted net income (loss), EBITDA and adjusted EBITDA have limitations as analytical tools. Some of the limitations applicable to these measures include: adjusted net income (loss), EBITDA and adjusted EBITDA do not reflect the impact of certain cash charges resulting from matters we consider not to be indicative of our ongoing operations; adjusted net income (loss), EBITDA and adjusted EBITDA do not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments; EBITDA and adjusted EBITDA do not reflect changes in, or cash requirements for, our working capital needs; EBITDA, and adjusted EBITDA do not reflect the interest expense, or the cash requirements necessary to service interest or principal payments, on our indebtedness or possible cash requirements related to our warrants; although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and EBITDA and adjusted EBITDA do not reflect any cash requirements for such replacements; and other companies in our industry may calculate adjusted net income (loss), EBITDA and adjusted EBITDA differently than we do, limiting their usefulness as comparative measures. Because of these limitations, adjusted net income (loss), EBITDA and adjusted EBITDA should not be considered in isolation from or as a substitute for performance measures calculated in accordance with GAAP. In addition, because derivations of adjusted net income (loss), EBITDA and adjusted EBITDA are not determined in accordance with GAAP, such measures are susceptible to varying calculations and not all companies calculate the measures in the same manner. As a result, derivations of net income (loss) and EBITDA, including adjusted net income (loss) and adjusted EBITDA, as presented may not be directly comparable to similarly titled measures presented by other companies.
For the foregoing reasons, each of adjusted net income (loss), EBITDA and adjusted EBITDA has significant limitations which affect its use as an indicator of our profitability. Accordingly, you are cautioned not to place undue reliance on this information.
(b)EBITDAR and adjusted EBITDAR are included as supplemental disclosures because we believe them to be useful solely as valuation metrics for airlines as their calculations isolate the effects of financing in general, the accounting effects of capital spending and acquisitions (primarily aircraft, which may be acquired directly, directly subject to acquisition debt, by capital lease or by operating lease, each of which is presented differently for accounting purposes), and income taxes, which may vary significantly between periods and for different airlines for reasons unrelated to the underlying value of a particular airline. However, EBITDAR and adjusted EBITDAR are not determined in accordance with GAAP, are susceptible to varying calculations and not all companies calculate the measure in the same manner. As a result, EBITDAR and adjusted EBITDAR, as presented, may not be directly comparable to similarly titled measures presented by other companies. In addition, EBITDAR and adjusted EBITDAR should not be viewed as measures of overall performance since they exclude aircraft rent, which is a normal, recurring cash operating expense that is necessary to operate our business. Accordingly, you are cautioned not to place undue reliance on this information.

(a)During the six months ended June 30, 2024, we recorded a $5 million non-cash valuation allowance against our U.S. federal and state net operating loss deferred tax assets, which largely do not expire, mainly as a result of being in a three-year historical cumulative pre-tax loss position and due to the loss generated during the three months ended March 31, 2024, which had no impact on cash taxes and is not reflective of our effective tax rate for deductible net operating losses generated or actual cash tax obligations created. Please refer to “Notes to Condensed Consolidated Financial Statements — 10. Income Taxes” for additional information.
(b)For each of the three and six months ended June 30, 2025 and 2024, there were no non-GAAP pre-tax adjustments.

Liquidity and Capital Resources
Overview
As of June 30, 2025, we had $766 million of total available liquidity, consisting of $561 million in unrestricted cash and cash equivalents and $205 million in total undrawn capacity on our Revolving Loan Facility. We had $560 million of total debt, net, of which $326 million is short-term and consists primarily of amounts outstanding under our Pre-delivery Credit Facilities. Our total debt, net is comprised of $386 million outstanding under our Pre-delivery Credit Facilities, $101 million outstanding under our pre-purchased miles facility with Barclays Bank Delaware (“Barclays”), $66 million in 10-year, low-interest loans (collectively, the “PSP Promissory Notes”) from the U.S. Department of the Treasury (the “Treasury”) and $12 million in secured indebtedness for our headquarters building, partially offset by $5 million in deferred debt acquisition costs.
In connection with the term loan facility entered into with the Treasury in September 2020, which was repaid in full in February 2022, and the PSP Promissory Notes, we issued warrants (the “Warrants”) to purchase 3,117,940 shares of FGHI common stock at a weighted-average price of $6.95 per share. These Warrants will expire during 2025 and 2026. In June 2024, the Treasury sold all such Warrants to a financial institution. During the six months ended June 30, 2025, 1,244,608 Warrants were exercised. We settled the exercises through a net share settlement of 248,893 shares of FGHI common stock and cash of less than $1 million. As of June 30, 2025, Warrants to purchase 1,873,332 shares of FGHI common stock were outstanding.
During the six months ended June 30, 2024, we reached an agreement with one of our aircraft lessors which eliminated requirements to pay maintenance reserves held as collateral in advance of our required performance of major maintenance activities on our aircraft leases. As a result of the agreement, the lessor disbursed back to us previously paid aircraft maintenance deposits of approximately $104 million. As a result, we no longer have any aircraft maintenance deposits with any of our lessors.
We continue to monitor our covenant compliance with various parties, including, but not limited to, our lenders and credit card processors. As of the date of this report, we are in compliance with all of our covenants.

Use of Cash and Future Obligations
We expect to meet our cash requirements for the next twelve months through use of our available cash and cash equivalents, our debt facilities, and cash flows from operating activities and sale-leaseback financing. We expect to meet our long-term cash requirements with cash flows from operating and financing activities, including, but not limited to, potential future borrowings under the Pre-delivery Credit Facilities, our undrawn Revolving Loan Facility and/or potential issuances of debt or equity. The Revolving Loan Facility also permits us to enter into additional indebtedness secured by our loyalty program and brand-related assets, to the extent such indebtedness is pari passu
36
to that of the Revolving Loan Facility. Our primary uses of cash are for working capital, aircraft PDPs, debt repayments and capital expenditures.
Our single largest capital commitment relates to the acquisition of aircraft. As of June 30, 2025, we operated all of our 164 aircraft under operating leases. PDPs relating to future deliveries under our agreement with Airbus are required at various times prior to each aircraft’s delivery date. As of June 30, 2025, our Pre-delivery Credit Facilities, which allow us to draw up to an aggregate of $476 million, had $386 million outstanding. As of June 30, 2025, we had $466 million of PDPs held by Airbus which have been partially financed by our Pre-delivery Credit Facilities.
As of June 30, 2025, we had a firm obligation to purchase 180 A320neo family aircraft and 9 additional spare engines to be delivered by 2031. Of our aircraft commitments, 22 had committed operating leases for deliveries occurring between 2025 and 2026. We intend to evaluate financing options for the remaining aircraft.
The following table summarizes current and long-term material cash requirements as of June 30, 2025, which we expect to fund primarily with operating and financing cash flows (in millions):
