MINNEAPOLIS, April 27, 2023 (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, 2023.

“Sun Country’s unique, diversified business model continues to deliver strong results,” said Jude Bricker, Chief Executive Officer of Sun Country. “The revenue environment remains resilient, as we saw a 20.8% increase in total average fare and a gain of 8.6 percentage points in load factor in the first quarter versus 2022. This demand strength helped deliver a first quarter GAAP operating income margin of 19.0% and an adjusted operating income margin of 19.9%⁽²⁾_, easily exceeding the first quarter of last year by over 9 percentage points. We delivered these outstanding results despite a winter season at our Minneapolis-St. Paul base that was the third snowiest on record. I want to thank our dedicated team of employees for their extraordinary efforts this winter.”

For the quarter ended March 31, 2023, Sun Country reported net income of $38 million and income before income tax of $50 million, on $294 million of revenue. Adjusted income before income tax for the quarter was $53 million⁽²⁾. GAAP operating income during the quarter was $56 million, while adjusted operating income was $58 million⁽²⁾_.  

“We continue to see strength across our scheduled service, charter and cargo businesses,” said Dave Davis, President and Chief Financial Officer. “Total revenue was up nearly 30% year-over-year, with Scheduled Service TRASM⁽³⁾ up 34.7% and TRASM⁽⁴⁾, including charter revenue, up 30.6% versus the first quarter of 2022. GAAP operating income increased 155% while adjusted operating income was up 157% year-over-year, generating a GAAP operating margin of 19.0% and an adjusted operating income margin of nearly 20% in our seasonally strongest quarter. During the first quarter, our unit costs were negatively impacted by decreased aircraft utilization levels. In the second quarter, we expect total block hour growth of at least 11% versus last year, and pressure on non-fuel CASM should ease during the year. We are also excited to have acquired five 737-900ER aircraft which are currently on lease to Oman Air. We will obtain the lease revenue from Oman Air until the expiration of the leases and the aircraft are delivered to us beginning in late 2024 and continuing through 2025. The 737-900ER is a new fleet variant for Sun Country and we expect it to create new opportunities for our network.”

Notable Highlights

• As of early April, the Company acquired five 737-900ER aircraft which are currently on lease to Oman Air. The aircraft will remain on lease to Oman Air until the leases expire in late 2024 and through 2025. Sun Country will take delivery of one aircraft in late 2024 and the other four throughout 2025.
• Extended the flight schedule through December 2023 to include 120 routes serving 90 airports.
• The Company repurchased 750,000 shares at a price of $19.75 from the underwriters of the Apollo Global Management secondary offering. The Company also completed its $25 million accelerated share repurchase program resulting in the repurchase of 480,932 additional shares. It still has $10.2 million authorized by the board of directors available for share repurchases.
• Named Jennifer Vogel as chair of the board of directors, the Company’s first female chairperson. She oversees a diverse board that is comprised of 50% women.

Capacity

System block hours flown during the first quarter of 2023 grew by 3.8% year over year. Cargo and charter block hours grew 5.2% and 32.9% respectively year over year, as more Amazon aircraft were available to fly and our contract charter business continues to expand. Scheduled service flying declined by 2.2% year over year and is expected to resume year over year growth in the second quarter.

Charter block hours under long-term contracts comprised 81% of the total charter flying performed in the first quarter of 2023. As the Company begins to normalize its aircraft utilization, it intends to pursue more ad-hoc charter flying.

Revenue

For the first quarter of 2023, the Company reported total revenue of $294 million, which was 29.8% more than the first quarter of 2022. The Company’s scheduled service TRASM⁽³⁾ of 13.8 cents in the first quarter of 2023 increased 34.7% year over year while scheduled service ASMs decreased 3.5%. The first quarter 2023 average total fare of $221 exceeded first quarter 2022 by 20.8% and included strong average ancillary revenue per passenger of $69. In the first quarter of 2023, the Company’s charter service revenue was $46 million, an increase of 40.5% year over year. On a rate basis, first quarter 2023 charter revenue per block hour was 5.7% higher than the rate in the first quarter of 2022.

In the first quarter of 2023, cargo revenue was $23 million, a 11.0% increase versus the first quarter of 2022. The variance was primarily driven by a 5.2% increase in block hours and the annual rate escalation which went into effect in mid-December 2022.

Cost

For the first quarter of 2023, total GAAP operating expenses increased 16.4% year over year, primarily due to a 12.0% increase in aircraft fuel expense and a 26.5% increase in salaries, wages, and benefits compared to first quarter 2022. Adjusted CASM⁽⁵⁾ in the first quarter increased 14.3% versus the first quarter 2022 on a decrease in daily aircraft utilization of 15.1% for the same period.

Balance Sheet and Liquidity

Total liquidity⁽⁷⁾ was $262 million on March 31, 2023, while the Company’s net debt⁽⁶⁾ was $449 million.

Non-GAAP Financial Measures

We sometimes use information that is derived from the 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, 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 expenses 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 as these operations do not create ASMs. 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.
