For the quarter ended December 31, 2023, Sun Country reported Income Before Income Tax of $7.7 million and Net Income of $5.6 million, on $245.5 million of revenue. Adjusted Income Before Income Tax for the quarter was $9.3 million⁽²⁾. GAAP Operating Income during the quarter was $17.1 million, producing an Operating Income Margin of 7.0%, while Adjusted Operating Income was $18.3 million⁽²⁾, resulting in an Adjusted Operating Income Margin of 7.4%⁽²⁾.

"We had a very successful 2023," said Dave Davis, President and Chief Financial Officer. "Our full year GAAP pre-tax margin was 9.0% and we produced an adjusted pre-tax margin of 9.9%⁽²⁾, which we expect to be the best, or among the best in the industry. Our cost performance improved throughout the year as our fourth quarter adjusted CASM⁽³⁾ of 7.3 cents was 2.2% lower than a year ago. Additionally, our 2023 GAAP diluted EPS was $1.23, our adjusted diluted EPS was $1.37⁽²⁾ and we generated a record⁽¹⁾ 21.4% adjusted EBITDA margin⁽²⁾ for the full year. These positive results allowed us to return cash to shareholders through share repurchases, which in 2023 totaled 4.2 million shares for $68.6 million. Total Capex spending in 2023 was $218.2 million, of which approximately $200 million was for additional aircraft. We expect these aircraft to provide almost all of the passenger lift we need through 2025, resulting in much lower capex levels in 2024."

Capacity

System block hours flown during the fourth quarter of 2023 grew by 10.4% year over year, while scheduled service ASMs increased 14.9%. Cargo block hours also grew 1.8% year over year during this time. For full year 2023, system block hours grew 9.8% driven by an increase in scheduled service block hours of 8.6%, an increase in cargo block hours of 5.8% and an increase of charter block hours of 18.9%.

Fourth quarter charter block hours grew 7.8% year over year driven by the continued growth in flying under long-term contracts, which comprised 70% of total charter flying versus 61% in the fourth quarter of 2022. Full year 2023 charter block hours under long-term contracts were 80% of total charter block hours versus 76% last year. This was mostly due to 25.7% growth in charter flying under long-term contracts versus the full year 2022.

Revenue

For the fourth quarter of 2023, the Company reported total revenue of $245.5 million, which was 8.1% more than the fourth quarter of 2022. The Company's scheduled service TRASM⁽⁴⁾ of 10.7 cents in the fourth quarter of 2023 decreased 9.1% year over year as scheduled service ASMs increased 14.9%. The fourth quarter 2023 total fare per passenger of $156.39 was less than fourth quarter 2022 by 11.8% while scheduled load factor of 84.7% was little changed versus last year. Full year 2023 scheduled service TRASM⁽⁴⁾ increased 7.6% while scheduled service ASMs increased 7.2% for the same time period. Full year total fare per passenger of $176.30 grew by 0.6% on a 2.8 percentage point increase in scheduled service load factor.

Charter service revenue is primarily generated through service provided to collegiate and professional sports teams, the U.S. Department of Defense, and casinos. In the fourth quarter of 2023, the Company's charter service revenue was $46.9 million, an increase of 8.8% year over year. For the full year, charter service revenue was $190.1 million, an increase of 17.6% versus last year.

Cargo revenue consists of revenue earned from flying cargo aircraft under the Air Transportation Services Agreement ("ATSA") with Amazon. In the fourth quarter of 2023, cargo revenue was $25.3 million, a 3.6% increase versus the fourth quarter of 2022. For the full year, charter service revenue was $99.7 million, an increase of 10.4% versus last year.

Cost

For the fourth quarter of 2023, total GAAP operating expenses increased 7.7% year-over-year versus a 10.4% increase in total block hours, primarily due to a 6.6% increase in salaries, wages, and benefits, a 5.0% increase in sales and marketing expense and a 2.6% increase in ground handling expense. This combination drove adjusted CASM⁽³⁾ in the fourth quarter lower by 2.2% versus the fourth quarter 2022. For the full year 2023, total GAAP operating expenses increased 9.9% while total system block hours grew 9.8% versus 2022. Salaries, wages and benefits grew 20.2%, while maintenance expense increased 30.0% in full year 2023, which were the primary drivers of the 6.4% year over year increase in adjusted CASM⁽³⁾.

Balance Sheet and Liquidity

Total liquidity⁽⁵⁾ was $205.2 million on December 31, 2023, while the Company's net debt⁽⁶⁾ was $517.2 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, 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, as well as depreciation and amortization recognized on certain assets that generate lease income as these operations do not create ASMs. During the year ended December 31, 2023, we entered into a series of transactions where we act as a lessor. As of December 31, 2023, we leased or subleased six aircraft. Depreciation and Amortization on these aircraft materially began during the three months ended June 30, 2023. Adjusted CASM further excludes special items and 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 long-term employee retention, rather than to motivate or reward operational performance for any 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.
