**Frontier Airlines Reports Fourth Quarter 2025 Financial Results**

DENVER - February 11, 2026 - Frontier Group Holdings, Inc. (Nasdaq: ULCC), parent company of Frontier Airlines, Inc., today reported financial results for the fourth quarter and full year 2025 and issued guidance for the first quarter and full year 2026.

**Highlights:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total revenue was $997 million on capacity which was flat to the corresponding 2024 quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Revenue per available seat mile ("RASM") was 10.17 cents, while RASM on a stage adjusted basis to 1,000 miles was 9.61 cents, slightly higher than the comparable 2024 quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cost per available seat mile ("CASM") was 9.67 cents, including fuel expense at an average cost of $2.44 per gallon; total operating expenses were $948 million, or $721 million excluding fuel, a non-GAAP measure, resulting in CASM excluding fuel of 7.36 cents

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net income was $53 million, or $0.23 per diluted share

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total liquidity was $874 million at year-end, including $220 million from the recently expanded revolving credit facility, representing approximately 23 percent of trailing twelve month revenue

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Announced a non-binding agreement with AerCap Holdings N.V. ("AerCap") for the early return of 24 A320neo aircraft in the second quarter of 2026 to right size the fleet and enhance the productivity of the airline. Additionally, AerCap will commit to 10 future sale-leaseback transactions for deliveries scheduled in 2028 and 2029, strengthening the parties' long-term partnership

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reached a non-binding framework agreement with Airbus SAS to adjust the delivery profile of the Company's orderbook to support a more measured long-term annual growth rate of approximately 10 percent through the deferral of 69 A320neo family aircraft otherwise scheduled to be delivered between 2027 and 2030

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Announced 23 new routes launching in March and April to destinations across the U.S. and Mexico along with 57 previously announced routes launched in late 2025 and early 2026, bolstering Frontier's commitment to be the leading high-value carrier in the top 20 U.S. metros

"As the quarter progressed, we benefited from a more constructive supply-demand environment, which, combined with our revenue management initiatives, supported fourth quarter results that were above guidance, overcoming sector-wide impacts of an extended government shutdown," commented Jimmy Dempsey, President and Chief Executive Officer. "As we look ahead to fiscal 2026, we are encouraged by demand trends and are laser focused on returning Frontier to profitability, strengthening our competitive position and driving enhanced value for our stakeholders. To achieve this, we're executing a strategy centered on four key priorities: rightsizing our fleet, strengthening our cost discipline, reducing cancellations and improving on-time performance, and maturing customer loyalty."

**Revenue Performance**

Total operating revenue for the fourth quarter of 2025 was $997 million on capacity consistent with the 2024 quarter, and an average stage length of 892 miles. RASM was 10.17 cents, while RASM on a stage adjusted basis to 1,000 miles was 9.61 cents, slightly higher than the comparable 2024 quarter, largely driven by the continued progress on the Company's revenue and network initiatives and overall moderation in competitive capacity which helped to overcome the November U.S government shutdown and the resulting FAA flight reduction directive. The Company estimates these two events negatively impacted revenue by approximately $30 million.

Total revenue per passenger was $117, consistent with the corresponding 2024 quarter. Flown load factor was up slightly compared to the corresponding 2024 quarter at 79 percent.

**Cost Performance**

Total operating expenses for the fourth quarter of 2025 totaled $948 million, including $227 million of fuel expenses at an average cost of $2.44 per gallon. Total adjusted operating expenses (excluding fuel), a non-GAAP measure, were $721 million.

CASM was 9.67 cents in the fourth quarter compared to 9.78 cents in the corresponding 2024 quarter. Adjusted CASM (excluding fuel), a non-GAAP measure, was 7.36 cents, 1 percent lower than the corresponding 2024 quarter, driven largely by sale-leaseback gains on higher fleet induction activity during the

------

quarter, offset by the impact from a 10 percent reduction in average daily aircraft utilization and higher station costs.

Frontier's full-year 2025 adjusted CASM + net interest, a non-GAAP measure, was 9.70 cents. Stage adjusted to 1,000 miles, full-year 2025 adjusted CASM + net interest was 9.30 cents, a relative advantage greater than 40 percent compared to the industry average<sup>1</sup>.

**Earnings**

Pre-tax income for the fourth quarter of 2025 was $52 million, reflecting a margin of 5.2 percent.

Net income for the fourth quarter of 2025 was $53 million, or $0.23 per diluted share based on approximately 230 million weighted-average shares outstanding in the quarter. The tax expense generated from pre-tax income was offset by the corresponding release of the cumulative valuation allowance from the utilization of a portion of net operating losses.

**Liquidity**

Total liquidity as of December 31, 2025 was $874 million, consisting of unrestricted cash and cash equivalents of $654 million and $220 million from the Company's revolving credit facility, which was expanded by $15 million in December 2025. No other changes were made to the contractual terms of the revolving credit facility. Total liquidity at year-end represents approximately 23 percent of trailing twelve month revenue.

**Fleet**

As of December 31, 2025, Frontier had a fleet of 176 Airbus single-aisle aircraft, as scheduled below, all financed through operating leases that expire between 2027 and 2037.

| A320ceo | 6 | 180 or 186 |

| A321ceo | 21 | 230 |
| A321neo | 60 | 240 |
| **Total fleet** | **176** |  |

---

Frontier took delivery of 10 A320neo family aircraft during the fourth quarter of 2025, including 7 A320neo aircraft and 3 A321neo aircraft, and 10 PW1100 GTF spare aircraft engines. The aircraft inductions increased the proportion of the fleet comprised of the more fuel-efficient A320neo family aircraft to 85 percent as of December 31, 2025, the highest of all major U.S. carriers. Frontier is "America's Greenest Airline" as measured by fuel efficiency (ASMs per fuel gallon consumed) compared to all other major U.S. carriers, generating 106 ASMs per gallon, consistent with the corresponding 2024 quarter.

*Planned Fleet Updates*

In early February 2026, as separately announced, the Company reached a non-binding letter of intent with AerCap Holdings N.V. to terminate the leases associated with 24 aircraft currently in operation which were otherwise scheduled to expire in the next two to eight years. These aircraft are expected to be returned in the second quarter of 2026. Additionally, AerCap will commit to 10 future sale-leaseback transactions for deliveries scheduled for the years 2028 and 2029.

Separately, the Company reached a non-binding framework agreement with Airbus SAS to defer the induction of 69 A320neo family aircraft which were otherwise expected to be contractually delivered between 2027 and 2030. The deferred aircraft are rescheduled to be delivered in 2031 through 2033.

------

The Company expects to finalize the definitive documents for both transactions by the first quarter of 2026 and incur certain one-time expenses associated with the completion of the lease termination agreement.

Upon closing, these fleet modifications, among other identified cost saving opportunities, are targeted to generate annual run-rate cost savings of approximately $200 million by 2027 and moderate the Company's long-term annual capacity growth to approximately 10 percent.

**Forward Guidance**

*The guidance provided below is based on the Company's current estimates and is not a guarantee of future performance. This guidance is subject to significant risks and uncertainties that could cause actual results to differ materially, including the risk factors discussed in the Company's reports on file with the Securities and Exchange Commission (the "SEC"). Frontier undertakes no duty to update any forward-looking statements or estimates, except as required by applicable law. Further, this guidance excludes special items and the reconciliation of non-GAAP measures to the comparable GAAP measures because such amounts cannot be determined at this time.*

The Company's first quarter 2026 adjusted (non-GAAP) diluted per share guidance, as noted below, reflects RASM on a stage adjusted basis to 1,000 miles currently trending to over 10 percent higher compared to the corresponding 2025 quarter, underpinned by a more constructive supply-demand environment and revenue management enhancements. Unit costs are expected to be relatively higher in the first quarter largely driven by fleet growth across lower scheduled utilization. Adjusted CASM (excluding fuel), a non-GAAP measure, is expected to ease as the year progresses as the Company right-sizes its fleet and generates benefits from the targeted cost savings as noted in the prior section. Full-year 2026 per share guidance reflects the expectation of a more constructive supply-demand environment and productivity gains beginning in the second quarter.

The forward guidance estimates are presented in the following table:

---

| | | |
|:---|:---|:---|
| | **First Quarter** | **Full Year** |
| | **2026**<sup>(a)</sup> | **2026**<sup>(a)</sup> |
| Adjusted (non-GAAP) diluted per share expected results<sup>(b)(c)</sup> | $(0.26) to $(0.44) | $(0.40) to $0.50 |
| Capacity growth (compared to corresponding prior year period) | (1) to (2) percent | ~10 percent |
| Pre-delivery deposits, net of refunds ($ millions)<sup>(d)</sup> |  | $(170) to $(210) |
| Other capital expenditures ($ millions)<sup>(d)(e)</sup> |  | $200 to $250 |

---

_________________

(a)Includes guidance on certain non-GAAP measures which excludes, among other things, special items as well as certain one-time expenses associated with the expected completion of the lease termination agreement as disclosed in the *Fleet* section of this release. The Company is unable to reconcile these forward-looking projections to GAAP as the nature or amount of such special items cannot be determined at this time.

(b)Based on the blended jet fuel curve on February 3, 2026, resulting in an average fuel cost (including fuel taxes and into-plane costs) of $2.50 per gallon for the first quarter of 2026 and $2.45 per gallon for full year 2026.

(c)Based on estimated weighted average shares outstanding of 229 million shares in the first quarter 2026 and $3 to $5 million expected tax expense; the Company's actual tax expense may be impacted by varying factors which may include, but are not limited to, the composition of items of income and expense recognized in the respective periods, including the amount of non-deductible or other similar items, the treatment of deferred tax assets and related valuation allowances.

(d)Assumes execution of the non-binding framework agreement with Airbus as disclosed in the *Fleet* section of this release. The Company expects its pre-delivery deposit balance to be reduced by $170 million to $210 million during the year as a result of the framework agreement, with a similar reduction expected in the related PDP financing facility balance.

(e)Assumes execution of the non-binding LOI with AerCap as disclosed in the *Fleet* section of this release; other capital expenditures includes capitalized heavy maintenance.

N/M = Not meaningful

(a)In periods of net income, the dilutive impact of the warrants outstanding relating to funding provided pursuant to the CARES Act and related legislation, any non-participating options and unvested restricted stock units are included in the diluted earnings per share calculations. In addition, most of the Company's outstanding options are participating securities and are therefore not expected to be part of the Company's diluted share count under the two-class method until they are exercised, but, in periods of net income, are included as an adjustment to the numerator of the Company's earnings per share calculation as they are eligible to participate in the Company's earnings. The participating securities impact has been subtracted from periods presented with positive net income in the computation of basic and diluted earnings per share. As of December 31, 2025, there were 0.2 million outstanding warrants and 0.6 million outstanding options. As of December 31, 2024, there were 3.1 million outstanding warrants and 2.2 million outstanding options.

**<u>Reconciliations of Non-GAAP Financial Information</u>**

The Company is providing below a reconciliation of GAAP financial information to the non-GAAP financial information provided. The non-GAAP financial information is included to provide supplemental disclosures because the Company believes they are useful additional indicators of, among other things, its operating and cost performance. These non-GAAP financial measures have limitations as analytical tools. Because of these limitations, determinations of the Company's operating performance or CASM excluding unrealized gains and losses, special items or other items should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP. These non-GAAP financial measures may be presented on a different basis than other companies using similarly titled non-GAAP financial measures.

(a)During 2024, the Company reached a legal settlement with a former lessor for breach of contract for a total of $40 million. $38 million of the settlement represents a one-time reimbursement of damages incurred and $2 million relates to the reimbursement of previously recorded legal expenses.

(b)During 2024, the Company reduced its existing capacity of the pre-delivery deposit financing facility from $365 million to $135 million. The downsize of the facility resulted in a one-time write-off of $1 million in unamortized deferred financing costs. This amount is a component of interest expense within the consolidated statements of operations.

(c)During 2024, a $5 million non-cash valuation allowance was recorded against the Company's 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, which has no impact on cash taxes and is not reflective of the Company's effective tax rate for deductible net operating losses generated or actual cash tax obligations created.

(d)Adjusted net income (loss) and adjusted pre-tax income (loss) are included as a supplemental disclosure because the Company believes they are useful indicators of its operating performance. Derivations of net income (loss) and pre-tax income (loss) are well-recognized performance measurements in the airline industry that are frequently used by the Company's management, as well as by investors, securities analysts and other interested parties, in comparing the operating performance of companies in the airline industry.

------

Adjusted net income (loss) and adjusted pre-tax income (loss) have limitations as analytical tools. Adjusted net income (loss) and adjusted pre-tax income (loss) do not reflect the impact of certain cash charges resulting from matters the Company considers not to be indicative of the Company's ongoing operations and do not reflect the Company's cash expenditures, or future requirements, for capital expenditures or contractual commitments, and other companies in the industry may calculate adjusted net income (loss) and adjusted pre-tax income (loss) differently than the Company does, limiting their usefulness as comparative measures. Because of these limitations, adjusted net income (loss) and adjusted pre-tax income (loss) 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) and adjusted pre-tax income (loss), including adjusted pre-tax margin, 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, including adjusted net income (loss) and adjusted pre-tax income (loss), as presented may not be directly comparable to similarly titled measures presented by other companies. For the foregoing reasons, adjusted net income (loss) and adjusted pre-tax income (loss) have significant limitations which affect their use as indicators of the Company's profitability. Accordingly, you are cautioned not to place undue reliance on this information.

__________________

(a)EBITDA and adjusted EBITDA are included as supplemental disclosures because the Company believes they are useful indicators of its operating performance. Derivations of EBITDA are well-recognized performance measurements in the airline industry that are frequently used by the Company's management, as well as by investors, securities analysts and other interested parties, in comparing the operating performance of companies in the industry.

EBITDA and adjusted EBITDA do not reflect the impact of certain cash charges resulting from matters the Company considers not to be indicative of its ongoing operations; the Company's cash expenditures, or future requirements, for capital expenditures or contractual commitments; changes in, or cash requirements for, the Company's working capital needs; or the interest expense, or the cash requirements necessary to service interest or principal payments, on the Company's indebtedness or possible cash requirements related to its warrants. Further, 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. Other companies in the airline industry may calculate EBITDA and adjusted EBITDA differently than the Company does, limiting their usefulness as comparative measures. Because of these limitations, 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 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 EBITDA, including adjusted EBITDA, as presented may not be directly comparable to similarly titled measures presented by other companies.

For the foregoing reasons, each of EBITDA and adjusted EBITDA have significant limitations which affect its use as an indicator of the Company's profitability. Accordingly, you are cautioned not to place undue reliance on this information.

(b)EBITDAR and adjusted EBITDAR are included as supplemental disclosures because the Company believes they are 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 measures 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 a measure of overall performance since they exclude aircraft rent, which is a normal, recurring cash operating expense that is necessary to operate the business. Accordingly, you are cautioned not to place undue reliance on this information.

(c)CASM (excluding fuel) and adjusted CASM (excluding fuel) are included as supplemental disclosures because the Company believes 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 the Company has limited control, impacts the comparability of period-to-period financial performance, and excluding allows management an additional tool to understand and analyze the Company's 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.

(d)Adjusted CASM is included as supplemental disclosure because the Company believes it is a useful metric to properly compare the Company's 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 the Company's management, as well as by investors, securities analysts and other interested parties in comparing the operating performance of companies in the airline industry. Additionally, the Company believes this metric is useful because it removes certain items that may not be indicative of 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 the Company believes they are useful metrics to properly compare its 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, the Company believes these metrics are useful because they remove certain items that may not be indicative of 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.

(c)CASM (excluding fuel) and adjusted CASM (excluding fuel) are included as supplemental disclosures because the Company believes 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 the Company has limited control, impacts the comparability of period-to-period financial performance, and excluding allows management an additional tool to understand and analyze the Company's 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.

(d)Adjusted CASM is included as supplemental disclosure because the Company believes it is a useful metric to properly compare the Company's 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 the Company's management, as well as by investors, securities analysts and other interested parties in comparing the operating performance of companies in the airline industry. Additionally, the Company believes this metric is useful because it removes certain items that may not be indicative of 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 the Company believes they are useful metrics to properly compare its 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, the Company believes these metrics are useful because they remove certain items that may not be indicative of 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)See "Reconciliation of Net Income (Loss) to Adjusted Net Income (Loss) and Pre-Tax Income (Loss) to Adjusted Pre-Tax Income (Loss)" above for discussion on adjusting items.

(b)Cost per share figures may not recalculate due to rounding.

(c)Adjusted earnings (loss) per share is included as a supplemental disclosure because the Company believes it is a useful indicator of operating performance. Derivations of net income are well-recognized performance measurements in the airline industry that are frequently used by management, as well as by investors, securities analysts and other interested parties in comparing the operating performance of companies in the industry.

Adjusted earnings (loss) per share has limitations as an analytical tool. Adjusted earnings (loss) per share does not reflect the impact of certain cash charges resulting from matters the Company considers not to be indicative of ongoing operations and does not reflect the cash expenditures, or future requirements, for capital expenditures or contractual commitments, and other companies in the industry may calculate Adjusted earnings (loss) per share differently than the Company does, limiting its usefulness as a comparative measure. Because of these limitations, Adjusted earnings (loss) per share 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 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, including Adjusted earnings (loss) per share, as presented may not be directly comparable to similarly titled measures presented by other companies. For the foregoing reasons, Adjusted earnings (loss) per share has significant limitations which affect its use as an indicator of profitability. Accordingly, you are cautioned not to place undue reliance on this information.
