Revenue Performance

Total operating revenue for the fourth quarter of 2023 was $891 million, reflecting a revenue per available seat mile (“RASM”) of 8.90 cents, on capacity growth of 15 percent compared to the 2022 quarter. The decrease in RASM from 10.45 cents in the 2022 quarter was driven by a 17 percent decrease in revenue per passenger to $110. Departures increased 20 percent compared to the 2022 quarter on a stage length which was 8 percent shorter.

Cost Performance

Total operating expenses for the fourth quarter of 2023 were $894 million, including $303 million of fuel expenses at an average cost of $3.18 per gallon. Total adjusted operating expenses (excluding fuel), a non-GAAP measure, were $590 million, including a $36 million benefit related to the extension during the quarter of four A320ceo aircraft leases that were otherwise scheduled to return in 2024.

CASM was 8.93 cents in the fourth quarter, 10 percent lower than the comparable 2022 quarter with fuel cost - comprising approximately 34 percent of total operating expenses - roughly in-line with the comparable 2022 quarter, and non-fuel expenses up 6 percent compared to the 2022 quarter on capacity growth of 15 percent. Fuel cost for the quarter reflects a 13 percent increase in consumption, net of a 3 percent improvement in fuel efficiency to 105 ASMs per gallon, offset by a 12 percent decrease in fuel cost per gallon, each compared to the 2022 quarter.

CASM (excluding fuel), a non-GAAP measure, was 5.91 cents, 8 percent lower than the comparable 2022 quarter. Adjusted (non-GAAP) CASM (excluding fuel) was 5.90 cents, also 8 percent lower than the comparable 2022 quarter.

Earnings

Pre-tax income for the fourth quarter of 2023 was $6 million, reflecting a pre-tax margin of 0.7 percent. Adjusted pre-tax income, a non-GAAP measure, was $7 million, reflecting an adjusted pre-tax margin of 0.8 percent.

Net loss for the fourth quarter of 2023 was $37 million, including the recognition of a $37 million non-cash valuation allowance against deferred tax assets. This allowance does not affect the Company's ability to utilize cumulative net operating losses against potential future income tax liabilities. Excluding special items, adjusted net income, a non-GAAP measure, was $1 million. Refer to “Reconciliations of Non-GAAP Financial Information” in the appendix of this release.

Cash and Liquidity

Unrestricted cash and cash equivalents as of December 31, 2023 was $609 million, or $139 million net of debt. The Company also has unencumbered loyalty and brand-related assets which it believes could generate significant additional liquidity, if desired.

Fleet

As of December 31, 2023, Frontier had a fleet of 136 Airbus single-aisle aircraft, as scheduled below, all financed through operating leases that expire between 2025 and 2035.

Equipment	Quantity	Seats
A320ceo	8	180 or 186
A320neo	82	186
A321ceo	21	230
A321neo	25	240
Total fleet	136

Frontier is “America's Greenest Airline” measured by ASMs per fuel gallon consumed. During the fourth quarter of 2023, Frontier generated 105 ASMs per gallon, a 3 percent improvement compared to the 2022 quarter.

Frontier took delivery of four A321neo aircraft during the fourth quarter of 2023, increasing the proportion of the fleet comprised of the more fuel-efficient A320neo family aircraft to 79 percent as of December 31, 2023, the highest of all major U.S. carriers. The A321neo is expected to unlock meaningful scale efficiencies by way of fuel savings and higher average seats per departure. As of December 31, 2023, the Company had commitments for an additional 210 aircraft to be delivered through 2029, including purchase commitments for 67 A320neo aircraft and 143 A321neo aircraft, representing 68 percent of future committed deliveries.

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 continues to see sequential improvement in the revenue environment as adjusted for seasonality. The Company is focusing its growth on overpriced and underserved "VFR" (Visiting Friends and Relatives) markets which, alongside network simplification, revenue diversification and cost savings initiatives, are expected to expand profitability in 2024.

First Quarter 2024

Capacity is anticipated to grow 5 to 7 percent compared to the 2023 quarter. Fuel costs are expected to be $2.85 to $2.95 per gallon based on the blended fuel curve on February 2, 2024. Adjusted (non-GAAP) total operating expenses (excluding fuel) are anticipated to be $645 to $660 million. The effective tax rate is estimated to be approximately 23 percent. Adjusted (non-GAAP) pre-tax loss margin is expected to be (4) to (7) percent (excluding special items).

Full Year 2024

Capacity is anticipated to grow 12 to 15 percent compared to 2023 and adjusted (non-GAAP) pre-tax margin is expected to be 3 to 6 percent (excluding special items). Fuel costs are expected to be $2.70 to $2.80 per gallon based on the blended fuel curve on February 2, 2024. Adjusted (non-GAAP) CASM (excluding fuel), stage-length adjusted to 1,000 miles, is expected to be down 1 to 3 percent over the prior year. Pre-delivery deposits, net of refunds, are expected to be $20 to $50 million and other capital expenditures are expected to be $160 to $180 million.

(a) In periods of net income, the dilutive impact of the 3.1 million 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 3.0 million 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.

Reconciliations of Non-GAAP Financial Information

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.

For the year ended December 31, 2022, adjustments represent $19 million in employee retention costs and $16 million in transaction costs, including banking, legal and accounting fees, incurred in connection with the terminated merger with Spirit, partially offset by $25 million received from Spirit for the reimbursement of incurred merger-related expenses.

(d) Represents $1 million of legal fees incurred due to the U.S. Department of Justice’s requests for information and deposition testimony from the Company related to the contemplated merger of Spirit and JetBlue Airways.

(e) On February 2, 2022, the Company repaid the loan under its facility with the U.S. Department of the Treasury, which resulted in a one-time write-off of the remaining $7 million in unamortized deferred financing costs. This amount is a component of interest expense.

(f) Represents the tax impact of the non-GAAP adjustments. The tax impact reflected for the fourth quarter of each year includes the impact of the update to the effective tax rate for the full year on the first, second and third quarter underlying results.

(g) In December 2023, the Company recorded a $37 million non-cash valuation allowance against its U.S. federal and state net operating loss deferred tax assets, which largely don't expire, mainly as a result of being in a three-year 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.

(h) 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 and pre-tax income 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.

(b) 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.

(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.
