Frontier Airlines Reports First Quarter 2023 Financial Results with Spring Break Outperforming Expectations

Frontier Airlines, Inc.

DENVER, May 03, 2023 (GLOBE NEWSWIRE) -- Frontier Group Holdings, Inc. (Nasdaq: ULCC), parent company of Frontier Airlines, Inc., today reported results for the first quarter of 2023 and issued guidance for second quarter and full year 2023.

First Quarter 2023 Summary:

• Achieved total operating revenues of $848 million, a record for any first quarter in company history and 40 percent higher than the 2022 quarter, resulting in a 19 percent increase in revenue per available seat mile ("RASM") on 18 percent higher capacity compared to the 2022 quarter

• Generated ancillary revenue of $80 per passenger, $11 more per passenger than the 2022 quarter

• Utilization averaged 11.8 hours per day in March 2023

• Realized a pre-tax margin of (2.0) percent and an adjusted (non-GAAP) pre-tax margin of (1.9) percent

• Ended the quarter in a strong liquidity position with $790 million of unrestricted cash and cash equivalents

• Took delivery of six A321neo aircraft during the first quarter, increasing the proportion of the fleet comprised of the more fuel-efficient A320neo family aircraft to 74 percent as of March 31, 2023, among the highest of all major U.S. carriers

• Generated 104 available seat miles ("ASM") per gallon, reaffirming Frontier's position as the most fuel-efficient of all major U.S. carriers and its ongoing commitment to being "America's Greenest Airline"

• Launched eight new routes, including five new routes from Phoenix, and announced 22 new routes to start the summer travel season, including significant expansion in Cleveland, San Francisco and Tampa

“Post-pandemic demand has increased due, in part, to work from home arrangements and flexible working schedules. We also see a change in passenger behavior with outsized demand on peak days and peak periods," commented Barry Biffle, President and CEO. "Having analyzed this new customer behavior, we are reshaping our capacity beginning in the second quarter to exploit this post-pandemic demand dynamic, and expect the changes to be fully deployed in the second half of 2023. We are excited about our planned network revisions and believe it will both reduce our execution risk through slightly lower total utilization while maximizing revenue and profits."

Mr. Biffle continued, "The operations performed well in the first quarter with utilization peaking in March at 11.8 hours. Ancillary revenue continued to grow, achieving an industry leading $80 per passenger in the first quarter, and we expect continued improvement through the year. While our overall capacity will be lower as a result of the shift to exploit the new demand dynamic, which will drive a corresponding unit cost impact, we believe our cost advantage of over $70¹ per passenger will widen further throughout the year, allowing Frontier to remain the lowest unit cost operator in the industry in spite of lower utilization on off-peak days and in off-peak periods. As a result, we are forecasting adjusted pre-tax margins in the range of 7 to 10 percent in the second quarter, our highest post-pandemic margin, further improving to 10 to 13 percent in the second half of 2023."

Revenue Performance

Total operating revenue for the first quarter of 2023 was $848 million, a record for any first quarter in company history, driven by RASM growth of 19 percent on capacity growth of 18 percent, as compared to the 2022 quarter. The RASM increase was driven by a nine percentage-point increase in load factor to 82.8 percent and an 11 percent increase in revenue per passenger to $124, both compared to the 2022 quarter.

Ancillary revenue per passenger for the first quarter was $80, 15 percent higher than the 2022 quarter.

Cost Performance

Total operating expenses for the first quarter of 2023 were $873 million, including $1 million in employee retention costs associated with the Company's terminated combination with Spirit Airlines, Inc. ("Spirit"). Excluding this item, adjusted (non-GAAP) total operating expenses were $872 million, including $292 million of fuel expenses at an average cost of $3.45 per gallon. Adjusted (non-GAAP) total operating expenses (excluding fuel) were $580 million.

Cost per available seat mile ("CASM") was 9.95 cents in the first quarter of 2023, while adjusted (non-GAAP) CASM was 9.94 cents. CASM (excluding fuel), a non-GAAP measure, was 6.62 cents, while adjusted (non-GAAP) CASM (excluding fuel) was 6.61 cents, 8 percent lower than the 2022 quarter.

Earnings

Pre-tax loss for the first quarter of 2023 was $(17) million, or $(16) million on an adjusted (non-GAAP) basis excluding special items, reflecting a pre-tax margin of (2.0) percent and an adjusted (non-GAAP) pre-tax margin of (1.9) percent.

Net loss for the first quarter of 2023 was $(13) million, or $(12) million on an adjusted (non-GAAP) basis excluding special items.

Cash and Liquidity

Unrestricted cash and cash equivalents as of March 31, 2023 was $790 million.

Fleet

As of March 31, 2023, Frontier had a fleet of 125 Airbus single-aisle aircraft, as scheduled below, all financed through operating leases that expire between 2023 and 2035.

Equipment	Quantity	Seats
A320neo	82	186
A320ceo	12	180 - 186
A321ceo	21	230

Frontier is America's Greenest Airline measured by ASMs per fuel gallon consumed. During the first quarter of 2023, Frontier generated 104 ASMs per gallon. To learn more about Frontier's sustainability initiatives, visit www.flygreener.com.

Frontier took delivery of its six A321neo aircraft during the first quarter of 2023, increasing the proportion of the fleet comprised of the more fuel-efficient A320neo family aircraft to 74 percent as of March 31, 2023, among 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 March 31, 2023, approximately 70 percent of future committed aircraft deliveries, including direct leases, are for A321neo aircraft.

As of March 31, 2023, the Company had commitments for an additional 225 aircraft to be delivered through 2029, including purchase commitments for 67 A320neo aircraft, 151 A321neo aircraft and another 7 A321neo aircraft through direct leases.

Airbus notified the Company of its intent to shift its remaining aircraft deliveries expected in 2023 by approximately one month, causing two incremental A321neo aircraft to shift into 2024 from 2023 in addition to the previous delays announced earlier this year. No net changes are expected in 2024.

In March 2023, the Company executed an agreement to extend by four years the lease terms on two A320ceo aircraft which otherwise were scheduled to terminate in the fourth quarter of 2023.

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 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 is adapting its network to more closely align with recent trends which reflect a change in passenger behavior with outsized demand on peak days and peak periods. The network changes, once fully deployed in the second half of 2023, are expected to lower execution risk and maximize revenue and profits, while also resulting in a downward revision to full-year 2023 capacity plans. Accordingly, full-year capacity is anticipated to grow 19 to 22 percent over 2022, while second quarter capacity is expected to grow 22 percent to 24 percent over the 2022 quarter.

Fuel costs in the second quarter are expected to be $2.65 to $2.75 per gallon and $2.80 to $2.90 per gallon for full-year 2023 based on the blended fuel curve on April 24, 2023.

Adjusted (non-GAAP) total operating expenses (excluding fuel) for the second quarter are anticipated to be $645 to $665 million and $2,500 to $2,550 million for full-year 2023.

The effective tax rate for both the second quarter and full-year 2023 is estimated to be approximately 24 percent.

Adjusted (non-GAAP) pre-tax margin (excluding special items) in the second quarter is expected to be in the range of 7 percent to 10 percent, 10 percent to 13 percent in the second half of 2023 and 7 percent to 9 percent for full-year 2023.

The current forward guidance estimates are presented in the following table:

	Second Quarter
	2023(a)
Capacity growth (versus 2Q 2022)(b)	22% to 24%
Adjusted (non-GAAP) total operating expenses (excluding fuel) ($ millions)(c)	$645 to $665
Average fuel cost per gallon(d)	$2.65 to $2.75
Effective tax rate	24%

1. 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 7.3 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.

1. For the three months ended March 31, 2023, adjustments represent $1 million in employee retention costs related to the terminated merger with Spirit Airlines, Inc. within transaction and merger-related costs. For the three months ended March 31, 2022, adjustments represent $8 million in transaction costs, including banking, legal and accounting fees, and $3 million in employee retention costs incurred in connection with the transaction.

2. 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.

3. Adjusted net income (loss) and adjusted pre-tax income (loss) are included as a supplemental disclosure because the Company believes they are a useful indicator 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.

__________________

1. 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; EBITDA and adjusted EBITDA do not reflect the Company's cash expenditures, or future requirements, for capital expenditures or contractual commitments; EBITDA and adjusted EBITDA do not reflect changes in, or cash requirements for, the Company's 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 the Company's indebtedness or possible cash requirements related to its 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 the airline industry may calculate EBITDA and adjusted EBITDA differently than the Company does, limiting its usefulness as a comparative measure. 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.
   
   

2. 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 isolates 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.

2. See “Reconciliation of Net Income (Loss) to Adjusted Net Income (Loss) and Adjusted Pre-tax Income (Loss)" above for discussion on adjusting items.

3. 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.

4. 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.

5. 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.
