Revenue of $254 million, impacted by late-June cancellations

GAAP diluted EPS of $0.03, operating income of $12 million and margin of 4.9%

Adj. diluted EPS(1) of $0.06, adjusted operating income(1) of $14 million and margin of 5.5%

MINNEAPOLIS. August 1, 2024. Sun Country Airlines Holdings, Inc. (“Sun Country Airlines,” “Sun Country,” the “Company”) (NASDAQ: SNCY) today reported financial results for its second quarter ended June 30, 2024.

“Sun Country is pleased to report our eighth consecutive profitable quarter with GAAP EPS of $0.03 and adjusted EPS of $0.06(1),” said Jude Bricker, Chief Executive Officer of Sun Country. “Despite a soft domestic revenue environment and some late-June operational challenges, we delivered a GAAP operating margin of 4.9% and an adjusted operating margin of 5.5%(1). Sun County’s financial results continue to be among the industry leaders at a particularly challenging time for low-cost airlines. This is the direct result of the unique, diversified model that we have built over the last 6 years. The revised agreement with Amazon that we announced in June will further strengthen the diversification of our revenue base and should significantly add to our earnings. We want to thank our employees for their hard work and dedication during a challenging operating period.”

Amounts presented in the tables above may not recalculate due to rounding For the quarter ended June 30, 2024, Sun Country reported net income of approximately $2 million and income before income tax of $3 million, on $254 million of revenue.

Adjusted income before income tax(1) for the quarter was approximately $5 million. GAAP operating income during the quarter was $12 million, while adjusted operating income(1) was $14 million, operating margin was 4.9% and adjusted operating margin(1) was 5.5%.

“Despite the challenging domestic revenue environment, and the fact that second quarter is a seasonally weaker quarter for Sun Country, we continued our two-year run of profitable quarters,” said Dave Davis, President and Chief Financial Officer. “Our results were driven by continued cost control, as total operating expense grew less than total block hours and adjusted CASM(2) decreased by 4.9% year over year. This is the third consecutive quarter where Sun Country’s unit costs declined on a year-over-year basis. The strength of the Sun Country model is driven by our diversified revenue streams, which other carriers cannot readily duplicate. We move capacity to the lines of business that will maximize profitability. Our revised agreement with Amazon is a great example of the power of this diversification. As new Amazon aircraft come into service starting in late-first quarter 2025, we intend to moderately shrink our scheduled service business to accommodate the Amazon growth. Our intent is to begin growing the scheduled service business again in 2026.”

•Entered into a revised Air Transport Services Agreement with Amazon that includes an extension of the agreement through 2030 with options to further extend through 2037, the addition of eight new freighter aircraft to our fleet and revised economics reflecting the realities of the post-pandemic cost environment.

•Launched a new mobile app to enhance the travel experience for Sun Country customers.

•Extended the existing leases on two 737-800 aircraft Sun Country has on lease to another carrier. These aircraft are now expected to redeliver to Sun Country in May 2025 and November 2025, respectively. Upon expiry of these subleases, the aircraft are expected to be inducted into the Sun Country passenger fleet.

•Extended the selling schedule through April 29, 2025 which includes more than 55 nonstop destinations from Minneapolis-St Paul next winter.

•Announced new international service from Milwaukee, WI to the Dominican Republic and Jamaica. Sun Country now offers the most international destinations from Milwaukee.

System block hours flown during the second quarter of 2024 grew by 8.9% year-over-year. All of this growth was allocated to the scheduled service business, resulting in an 18.2% increase in scheduled service ASMs. Scheduled service ASM growth will slow substantially in the third quarter of 2024 to an expected 7 to 8% increase over third quarter 2023. Cargo block hours declined in the second quarter by 2.4% year-over-year due to scheduled maintenance during the quarter.

Charter block hours under long-term contracts comprised over 77% of the total charter flying performed in the second quarter of 2024. Second quarter ad-hoc charter block hours grew 57% versus a year ago. Charter flying was also optimized to minimize non-productive ferry flights, resulting in improved performance on an overall block hours decline of 10.2% year-over-year.

The domestic market continued to be impacted by overcapacity in the second quarter which pressured unit revenue. The Company reported total revenue of $254 million for the second quarter, which was 2.6% less than the second quarter of 2023. Scheduled service TRASM(3) of 10.03 cents decreased 21.3% year-over-year, while scheduled service ASMs increased 18.2%. The second quarter 2024 total fare per scheduled passenger of $142 was lower than second quarter 2023 by 20.1% as scheduled service revenue passengers grew 16.1%. The Company’s second quarter charter service revenue was $51 million, an increase of 2.8% year-over-year.

On a rate basis, second quarter 2024 charter revenue per block hour was 14.4% higher than the rate in the second quarter of 2023. This rate increase includes the impact of higher fuel prices.

In the second quarter of 2024, cargo revenue was $25 million, a 1.7% increase versus the second quarter of 2023. The variance was primarily driven by the annual rate escalation which went into effect in mid-December 2023.

Sun Country continues to demonstrate excellent cost management, with second quarter CASM falling 5.1% and adjusted CASM(2) falling 4.9% year-over-year. Total GAAP operating expenses increased 7.3% year-over-year, primarily due to an 18.8% increase in fuel expense resulting from a 5.5% increase in fuel price and a 19.6% increase in scheduled service block hours. Non fuel expenses that exceeded block hour growth included ground handling expenses, which increased 16.6% driven by a 12% increase in passenger segment departures as well as an increase in rate, and landing fees and airport rent which increased 14.9% due to the expiration of COVID assistance that airports have used to limit rate increases. The remaining expenses grew less than total block hour growth.

Total liquidity(4) was $153 million on June 30, 2024, while the Company’s net debt(5) was $552 million.

As of June 30, 2024, the Company had 44 aircraft in its passenger service fleet, operated 12 freighter aircraft in its cargo operation and had seven aircraft that are currently on lease to unaffiliated airlines.

The following tables presents key operating statistics and metrics for the three and six months ended June 30, 2024 and 2023.

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.

Reconciliation of GAAP Net Income to Adjusted EBITDA Dollars in millions – Unaudited - amounts may not recalculate due to rounding
The following tables present the reconciliation of net income to adjusted EBITDA for the periods presented below.

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 June 30, 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.
