GAAP diluted EPS of $0.64 and operating income of $55 million

MINNEAPOLIS, May 07, 2024 (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, 2024.

"Sun Country's diversified business model produced another strong first quarter with margins that we expect to finish at the top of the industry," said Jude Bricker, Chief Executive Officer of Sun Country. "Total revenue was up 5.9% versus the first quarter of 2023, reaching a record quarterly high of $311 million⁽¹⁾ while costs remained in check. We continue to grow in all areas of our business, with total block hours growing by nearly 10% and scheduled passenger service ASMs growing by over 16%. Total passenger revenue per ASM (TRASM) declined by 9.6%, driven by both our growth as well as significant capacity additions by other airlines in some of our markets. Our strong results would not have been possible without our dedicated employees who delivered the number one completion factor in the industry during the quarter."

For the quarter ended March 31, 2024, Sun Country reported net income of $35 million and income before income tax of $47 million, on $311 million of revenue. Adjusted income before income tax⁽²⁾ for the quarter was $48 million. GAAP operating income during the quarter was $55 million, while adjusted operating income⁽²⁾ was $57 million, operating margin was 17.7% and adjusted operating margin⁽²⁾ was 18.2%_.  

"We had another good first quarter which is historically our strongest," said Dave Davis, President and Chief Financial Officer.   "Our performance was particularly strong in two areas.   First, our growth was not constrained by staffing issues, leading to a nearly 10% improvement in aircraft utilization.   Second, we continued to demonstrate strong cost control with a year over year decline in adjusted CASM⁽³⁾, continuing a trend started in the fourth quarter of last year.   This improvement came despite a planned investment in increased maintenance expenses.   Our balance sheet remains healthy.   During the quarter, we repurchased $11.5 million worth of SNCY shares through our existing share repurchase program.   First quarter capex was $29.7 million and we have acquired all of the aircraft we need to support our expected growth through at least 2025."

Notable Highlights

• Extended the selling schedule through December 2024. The company will operate 122 routes serving 108 airports.
• The company acquired three aircraft in the first quarter of this year. One aircraft was purchased for cash and another was taken on finance lease. These aircraft are expected to enter revenue service in the second quarter. The third aircraft was purchased early in the quarter and is the seventh aircraft that is on lease to another airline.
• The company repurchased 755,000 shares at an average price of $15.22 during the first quarter.
  
  

Capacity

System block hours flown during the first quarter of 2024 grew by 9.6% year-over-year due to a 16.2% increase in scheduled service block hours. Both cargo block hours and charter block hours declined in the first quarter by 1.1% and 3.0% respectively year-over-year. Cargo block hours were influenced by scheduled maintenance in the quarter while charter block hours were optimized to minimize non-productive ferry flights.

Charter block hours under long-term contracts comprised 75% of the total charter flying performed in the first quarter of 2024. As the Company continues to normalize its aircraft utilization, it is pursuing more ad-hoc charter flying.

Revenue

For the first quarter of 2024, the Company reported total revenue of $311 million, which was 5.9% more than the first quarter of 2023. The Company's scheduled service TRASM⁽⁴⁾ of 12.20 cents in the first quarter of 2024 decreased 11.7% year-over-year, while scheduled service ASMs increased 16.4%. The first quarter 2024 total fare per scheduled passenger of $196 was lower than first quarter 2023 by 11.3% as scheduled service revenue passengers grew 16.0%. In the first quarter of 2024, the Company's charter service revenue was $47 million, an increase of 2.4% year-over-year. On a rate basis, first quarter 2024 charter revenue per block hour was 5.6% higher than the rate in the first quarter of 2023. This rate increase includes the impact of lower fuel prices which reduced the fuel reimbursement amount that we received from our charter customers by 20% year-over-year.

In the first quarter of 2024, cargo revenue was $24 million, a 2.5% increase versus the first quarter of 2023. The variance was primarily driven by the annual rate escalation which went into effect in mid-December 2023.

Cost

For the first quarter of 2024, total GAAP operating expenses increased 7.5% year-over-year, primarily due to a 29.0% increase in maintenance expense from aircraft heavy maintenance and a 34.6% in landing fees and airport rent as the COVID assistance used by airports to keep rates lower expired. Fuel expense decreased by 2.7% compared to first quarter 2023. This combination drove first quarter CASM to decline 5.4% and adjusted CASM⁽³⁾ to decrease 0.1% versus last year.

Balance Sheet and Liquidity

Total liquidity⁽⁵⁾ was $179 million on March 31, 2024, while the Company's net debt⁽⁶⁾ was $565 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 our aircraft and flight equipment held for operating lease as these operations do not create ASMs. We have entered into a series of transactions where we act as an aircraft lessor. As of March 31, 2024, we leased or subleased seven aircraft. Depreciation expense on these aircraft materially began during the three months ended June 30, 2023. 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.
