MINNEAPOLIS, May 01, 2025 (GLOBE NEWSWIRE) -- Sun Country Airlines Holdings, Inc. (“Sun Country Airlines,” “Sun Country,” the “Company”) (NASDAQ: SNCY) today reported financial results for its first quarter ended March 31, 2025.

“Sun Country is pleased to report our eleventh consecutive profitable quarter with GAAP EPS of $0.66 and adjusted diluted EPS of $0.72⁽²⁾,” said Jude Bricker, Chief Executive Officer of Sun Country. “Despite the challenging scheduled revenue environment, we delivered $327 million of total revenue, our highest quarterly total⁽¹⁾_, along with $56 million of GAAP operating income and $60 million of adjusted operating income⁽²⁾, also a quarterly record⁽¹⁾. Robust growth in our charter and cargo businesses helped offset lower than expected scheduled service revenue, demonstrating the effectiveness of our diversified business model. As a result, we were able to produce a GAAP operating margin of 17.2% and adjusted operating margin⁽²⁾ of 18.3% which was higher than last year. In addition to our excellent performance, our board of directors has approved a $25 million share repurchase authorization. As always, we want to thank our employees for their hard work and dedication during a challenging operating period.”

For the quarter ended March 31, 2025, Sun Country reported net income of approximately $37 million and income before income tax of $48 million, on $327 million of revenue. Adjusted income before income tax⁽²⁾ for the quarter was approximately $52 million. GAAP operating income during the quarter was $56 million, while adjusted operating income⁽²⁾ was $60 million, and GAAP operating margin was 17.2% and adjusted operating margin⁽²⁾ was 18.3%.

“Our first quarter results reflect the continued earnings power of our diversified business model,” said Bill Trousdale, Interim Chief Financial Officer. “Both cargo and charter revenue growth exceeded their block hour growth for the quarter. This strength offset the weaker first quarter scheduled service demand environment that we experienced. We expect strength in the charter and cargo businesses to persist, especially as we plan to add five more cargo aircraft to the fleet by the end of the third quarter, bringing us to a total of 20 cargo aircraft. We had been proactively re-sizing our scheduled service business to grow our cargo business at improved economics even before we saw close-in demand weakness in February. We believe this will position us well to rely on other portions of our business that are not as impacted by the macro weakness that we witnessed in the first quarter.”

Notable Highlights

• Completed a secondary public offering which resulted in certain investment funds managed by affiliates of Apollo Global Management, Inc. exiting their position in Sun Country. Through this process the Company purchased $10 million of shares acquired from the underwriters at a price per share equivalent to the price at which the underwriters purchased the shares from the investment funds managed by affiliates of Apollo Global Management, Inc.
• Sun Country and its flight attendants, represented by the International Brotherhood of Teamsters, ratified a new collective bargaining agreement.
• Sun Country reached agreement with the dispatchers represented by the Transport Workers Union (TWU) which was ratified on February 13.
• The Company entered into a four-year $75 million Revolving Credit Facility which represents a $50 million increase from the previous revolver.
• Entered into an agreement with Synchrony Bank to be the issuer of the Sun Country credit card. The partnership is expected to launch later this year.
• Taken possession of three incremental cargo aircraft. One aircraft entered service late in the quarter and the other two are currently in the induction process and expected to enter service during the second quarter.
• Named the recipient of the Air Transport World (ATW) Airline Market Leader Award for 2025.
• Extended the selling schedule through December 9, 2025.

Capacity

System block hours flown during the first quarter of 2025 grew by 5.8% year-over-year. All of this growth was allocated to the passenger segment, resulting in a 6.7% increase in scheduled service ASMs and 10.7% increase in charter block hours. Scheduled service ASMs are expected to decline in the second quarter 2025 by approximately seven percent to allow for planned cargo segment growth. Cargo block hours declined in the first quarter by 1.1% year-over-year due to normalization of the cargo schedules and some weather events throughout the quarter.

Revenue

The scheduled service domestic market was impacted by weaker off-peak demand in February which pressured unit revenue for the quarter. The Company reported total revenue of $327 million for the first quarter, which was 4.9% greater than the first quarter of 2024. Scheduled service TRASM⁽³⁾ of 11.63 cents decreased 4.7% year-over-year, while scheduled service ASMs increased 6.7%. The first quarter 2025 total fare per scheduled passenger of $198 was higher than first quarter 2024 by 1.0% but was offset by a 3.9 percentage point decline in load factor year over year. The Company’s first quarter charter service revenue was $55 million, an increase of 15.6% year-over-year, exceeding charter block hour growth of only 10.7% and offsetting the impact of lower fuel cost reimbursements from our customers.

In the first quarter of 2025, cargo revenue was $28 million, a 17.6% increase versus the first quarter of 2024 on a 1.1% decline in cargo block hours. This improvement was primarily driven by the annual rate escalation which went into effect in mid-December 2024 and the continuation of the new Amazon contract rates which went into effect in June 2024.

Cost

First quarter CASM fell 1.6%, while adjusted CASM⁽⁴⁾ was up 3.5% year-over-year. Total GAAP operating expenses increased 5.5% year-over-year, primarily due to a 5.8% increase in total block hours. The most significant non-fuel expenses that grew faster than the level of flying included salaries, maintenance, ground handling and landing fees. Salaries, which increased 12.9%, were mostly driven by an 8% increase in pilot headcount and a 6% contractual pilot wage scale increase that occurred at the end of 2024. Maintenance expenses, which increased 12.2%, were impacted by an increase in non-routine maintenance events and growth in the fleet and operations. Ground handling costs increased 24.6%, driven by a 5% increase in Passenger segment departures and a combination of rate increases at our outsourced ground stations as well as operational challenges in the quarter. Landing fees and airport rent increased 14.3% due to rate increases at airports.

Balance Sheet and Liquidity

Total liquidity⁽⁵⁾ was $227 million on March 31, 2025, while the Company’s net debt⁽⁶⁾ was $447 million.

Non-GAAP Financial Measures

We sometimes use information that is derived from the Condensed Consolidated Financial Statements, but that is not presented in accordance with GAAP. We believe these non-GAAP measures provide a meaningful comparison of our results to others in the airline industry and our prior year results. Investors should consider these non-GAAP financial measures in addition to, and not as a substitute for, our financial performance measures prepared in accordance with GAAP. Further, our non-GAAP information may be different from the non-GAAP information provided by other companies. We believe certain charges included in our operating expenses on a GAAP basis make it difficult to compare our current period results to prior periods as well as future periods and guidance. The tables below show a reconciliation of non-GAAP financial measures used in this document to the most directly comparable GAAP financial measures.

NON-GAAP FINANCIAL MEASURES

Adjusted Operating Income, Adjusted Operating Income Margin, Adjusted Income Before Income Tax, Adjusted Pre-tax Margin, Adjusted Net Income, Adjusted Net Income per Share, Adjusted EBITDA and Adjusted EBITDA Margin

Adjusted Operating Income, Adjusted Operating Income Margin, Adjusted Income Before Income Tax, Adjusted Pre-tax Margin, Adjusted Net Income, Adjusted Net Income per share, Adjusted EBITDA and Adjusted EBITDA Margin are non-GAAP measures included as supplemental disclosure because we believe they are useful indicators of our operating performance. Derivations of Operating Income and Net Income 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.

The measures described above have limitations as analytical tools. Some of the limitations applicable to these measures include: they do not reflect the impact of certain cash and non-cash charges resulting from matters we consider not to be indicative of our ongoing operations; and other companies in our industry may calculate these non-GAAP measures differently than we do, limiting each measure’s usefulness as a comparative measure. Because of these limitations, the following non-GAAP measures should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP and may not be the same as or comparable to similarly titled measures presented by other companies due to the possible differences in the method of calculation and in the items being adjusted.

For the aforementioned reasons, Adjusted Operating Income, Adjusted Operating Income Margin, Adjusted Income Before Income Tax, Adjusted Pre-tax Margin, Adjusted Net Income, Adjusted Net Income per Share, Adjusted EBITDA and Adjusted EBITDA Margin have significant limitations which affect their use as indicators of our profitability. Accordingly, readers are cautioned not to place undue reliance on this information.

Adjusted CASM

Adjusted CASM is a non-GAAP measure derived from CASM by excluding fuel costs, costs related to our cargo operations, stock based compensation, depreciation and amortization recognized on certain assets that generate lease income, certain commissions and other costs of selling our vacations product from this measure as these costs are unrelated to our airline operations and improve comparability to our peers. Adjusted CASM is an important measure used by management and by our board of directors in assessing quarterly and annual cost performance. Adjusted CASM is also a measure commonly used by industry analysts and we believe it is an important metric by which they compare our airline to others in the industry, although other airlines may exclude certain other costs in their calculation of Adjusted CASM. The measure is also the subject of frequent questions from investors.

Adjusted CASM excludes fuel costs. By excluding volatile fuel costs that are outside of our control from our unit metrics, we believe that we have better visibility into the results of operations and our non-fuel cost initiatives. Our industry is highly competitive and is characterized by high fixed costs, so even a small reduction in non-fuel operating costs can lead to a significant improvement in operating results. In addition, we believe that all domestic carriers are similarly impacted by changes in jet fuel costs over the long run, so it is important for management and investors to understand the impact and trends in company-specific cost drivers, such as labor rates, aircraft and maintenance costs, and productivity, which are more controllable by management.

We have excluded costs related to the cargo operations and depreciation recognized on certain assets that generate lease income as these operations do not create ASMs. We have entered into a series of transactions where we serve as a lessor. As of March 31, 2025, we leased or subleased six aircraft. Adjusted CASM further excludes other adjustments, as defined in the relevant reporting period, that are not representative of the ongoing costs necessary to our airline operations and may improve comparability between periods. We also exclude stock compensation expense when computing Adjusted CASM. The Company’s compensation strategy includes the use of stock-based compensation to attract and retain employees and executives and is principally aimed at aligning their interests with those of our stockholders and at long-term employee retention, rather than to motivate or reward operational performance for any particular period. Thus, stock-based compensation expense varies for reasons that are generally unrelated to operational decisions and performance in any period.

As derivations of Adjusted CASM 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 Adjusted CASM as presented may not be directly comparable to similarly titled measures presented by other companies. Adjusted CASM should not be considered in isolation or as a replacement for CASM. For the aforementioned reasons, Adjusted CASM has significant limitations which affect its use as an indicator of our profitability. Accordingly, readers are cautioned not to place undue reliance on this information.
