Allegiant Travel Company (ALGT)

Item 1. Business

Overview

We are a leisure travel company focused on providing travel and leisure services and products to residents of under-served cities in the United States. Our vision is to be the leading airline in the communities we serve, offering reliable, nonstop travel at unbeatable value. We were founded in 1997 and, in conjunction with our initial public offering in 2006, we incorporated in the state of Nevada. Our unique business model provides diversified revenue streams from various travel services and product offerings which distinguish us from other travel companies. We operate a low-cost, low utilization passenger airline marketed primarily to leisure travelers in under-served cities, allowing us to sell air transportation both on a stand-alone basis and bundled with the sale of air-related and third party services and products. In addition, we provide air transportation under fixed fee flight arrangements. Our developed nation-wide route network, pricing philosophy, direct distribution, award-winning loyalty programs, advertising, and product offerings built around relationships with premier leisure companies, are all intended to appeal to leisure travelers and make it attractive for them to purchase air travel and related services and products from us.

Below is a brief description of the travel services and products we provide to our airline customers:

Scheduled service air transportation. We provide scheduled air transportation on limited-frequency, nonstop flights predominantly between under-served cities and popular leisure destinations. As of February 1, 2026, we were selling travel on 578 routes to 126 cities. Of these routes, 433 of them are unique city pairs which do not have any current nonstop competition with other airlines. As of February 1, 2026, our operating fleet consisted of 16 Boeing 737 series aircraft and 106 Airbus A320 series aircraft. In this document, references to "Airbus A320 series aircraft" are intended to describe both Airbus A319 and A320 aircraft.

Ancillary air-related products and services. We provide unbundled air-related services and products in conjunction with air transportation for an additional cost to customers. These optional air-related services and products include larger seats, baggage fees, advance seat assignments, our own travel protection product, change fees, use of our call center for purchases, priority boarding, a customer convenience fee, food and beverage purchases on board, and other air-related services. We also offer certain bundles of air-ancillary products where customers can choose popular combinations of these products at a discounted price to the combined individual prices. The revenue from ancillary air-related products and services is reflected in the passenger revenue income statement line item, along with scheduled service air transportation revenue and travel point redemptions from our co-brand Allegiant credit card and our non-card loyalty program.

Third party products and services. We offer third party travel products such as hotel rooms, rental cars, and travel insurance from a third party insurer for sale to our passengers. The marketing component of revenue related to our co-brand Allegiant credit card is also included in this category.

Fixed fee contract air transportation. We provide air transportation through fixed fee agreements and charter service on a year-round and ad hoc basis.

Proposed Acquisition of Sun Country Airlines

On January 11, 2026, we announced that we plan to acquire Sun Country Airlines Holdings, Inc. (“Sun Country”) pursuant to an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the Merger Agreement, each existing share of Sun Country common stock will be converted into the right to receive (i) $4.10 in cash, without interest and (ii) 0.1557 shares of our common stock.

The Merger Agreement provides that, immediately following the effective date of the proposed acquisition of Sun Country, we will increase the size of our board of directors by three members, which will be comprised of three directors designated by Sun Country, one of whom will be Jude Bricker, the president and chief executive officer of Sun Country, and two of whom will be current members of Sun Country’s board of directors who are reasonably acceptable to our nominating and governance committee.

Completion of the proposed acquisition of Sun Country is subject to the satisfaction or waiver of certain closing conditions, including, among other things that (1) our stockholders approve the issuance of shares of our common stock pursuant to the Merger Agreement, and the Sun Country stockholders approve the Merger Agreement, (2) the waiting period applicable to the closing under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”) (and any customary timing agreement with any governmental entity to toll, stay or extend such waiting period, or to delay or not to consummate the mergers) will have expired or been terminated, (3) all consents, registrations, notices, waivers, exemptions, approvals, confirmations, clearances, permits, certificates, orders and authorizations required to be obtained from, or delivered to, as applicable, the U.S. Federal Aviation Administration (“FAA”), the U.S. Department of Transportation (“DOT”) and the U.S. Department of Homeland Security (“DHS”), including the Transportation Security Administration ("TSA"), in connection with the closing will have been obtained or delivered, as applicable, (4) there will be no law in effect, whether preliminary, temporary or permanent, which makes the proposed transaction illegal or prohibits or otherwise prevents the closing, (5) the registration statement to be filed by us with the Securities and Exchange Commission (the “SEC”) pursuant to the Merger Agreement, will have become effective in accordance with the provisions of the Securities Act of 1933, as amended, and no stop order

suspending the effectiveness of the registration statement will have been issued by the SEC and remain in effect and no proceeding to that effect will have been commenced or threatened unless subsequently withdrawn; and (6) the shares of our common stock to be issued in the proposed acquisition of Sun Country will have been authorized and approved for listing on Nasdaq.

We and Sun Country each make certain customary representations, warranties and covenants, as applicable, in the Merger Agreement, including, among others, covenants regarding the conduct of our respective businesses during the pendency of the transactions contemplated by the Merger Agreement.

In addition, we and Sun Country have agreed, among other things, that we will not (1) solicit alternative transactions, (2) participate in or facilitate any discussions or negotiations relating to alternative transactions, (3) furnish any non-public information in connection with alternative transactions or (4) enter into any agreement relating to alternative transactions, except under limited circumstances described in the Merger Agreement. However, in certain circumstances, we or Sun Country may terminate the Merger Agreement to enter into a definitive agreement for a superior proposal as specified in the Merger Agreement.

The Merger Agreement contains certain customary termination rights for us and Sun Country, including, without limitation, a right for either party to terminate if the proposed acquisition of Sun Country is not consummated on or before January 11, 2027, subject to certain extensions if needed to obtain required regulatory approvals, or if a required stockholder approval is not obtained. If the Merger Agreement is terminated under certain circumstances relating to a change of recommendation by our board or by our entry into a definitive agreement for a superior proposal, we will be required to pay Sun Country a termination fee of $52,230,000. Conversely, if the Merger Agreement is terminated under certain circumstances relating to a change of recommendation by the Sun Country board or by Sun Country’s entry into a definitive agreement for a superior proposal, Sun Country will be required to pay us a termination fee of $33,020,000. In addition, we will be required to pay Sun Country a termination fee of $30,000,000 if the Merger Agreement is terminated under certain circumstances relating to the failure of the parties to obtain the expiration or termination of the waiting period under the HSR Act (“HSR Clearance”), or if there is a final, non-appealable law or order prohibiting the consummation of the transactions relating to HSR Clearance.

If the Merger Agreement is terminated under certain circumstances in which a required stockholder approval is not obtained, either party may be required to reimburse the other party’s expenses up to $11,000,000. The Merger Agreement also provides the methodology by which certain expenses will be borne.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to full text of the Merger Agreement, which has previously been filed with the SEC.

Allegiant ONE

We continue to sharpen our focus on our strength - our unique airline and seeking to return to historical margins. We fly so the one person who couldn't travel, could. Our vision is to be the leading airline in the communities we serve, offering reliable, nonstop travel at an unbeatable value. We have coined our Company strategy as "Allegiant ONE" which currently includes the following Company goals:

•maintaining our foundation of providing affordably accessible all-nonstop air travel while refining and strengthening our air travel product

•expanding our already broad domestic network as we have identified more than 1,400 incremental routes of which more than 75 percent currently have no nonstop service

•earning the right to grow by seeking to restore historical margins and strengthening our balance sheet

•taking advantage of the foundational technology we now have in place to leverage and embrace advancing technology (such as AI) to offer increased value to our customers and be able to scale more productively

•increasing peak period service to 1,000 daily departures over time as we earn the right to grow

•achieving at least 15 percent of new revenue from sources other than capacity growth

•seeking to offer (subject to government approval) transborder international scheduled service

•utilizing our customer data to offer personalized and more attractive product offerings

•transforming our eCommerce strategy to create a frictionless experience for our customers and drive increased air ancillary and third party products revenue generation

•expanding our award-winning co-brand credit card program and our non-card loyalty program

•revisiting our marketing strategy to be more surgical and measured

In our pursuit of Allegiant ONE, on January 11, 2026, we entered into an agreement to acquire Sun Country Airlines Holdings, Inc. ("Sun Country"), subject to shareholder approval and required regulatory review. The proposed transaction is anticipated to close in the second half of 2026. We expect this combination to support our Allegiant ONE objectives by broadening our network and improving our ability to flex capacity in response to market and demand conditions. We believe Sun Country's route network and operations are complementary to ours and will support our ability to expand year-round scheduled service, charter, and cargo capabilities while offering customers more destinations and more frequent service. We believe the combined organization will support long-term strategy growth and investment, consistent with our commitment to providing affordable leisure travel and creating long-term value for our shareholders.

Also in pursuit of Allegiant ONE, and consistent with our strategy to focus on the airline as our core business, we completed the sale of Sunseeker Resort at Charlotte Harbor (the "Resort" or "Sunseeker Resort") on September 4, 2025.

Our principal executive offices are located at 1201 N. Town Center Drive, Las Vegas, Nevada 89144. Our telephone number is (702) 851-7300. Our website address is allegiantair.com.

Unique Business Model

We have developed a unique business model that primarily focuses on leisure travelers in under-served cities. The business model has evolved as our experienced management team has looked differently at the traditional way business has been conducted in the airline and travel industries. Our focus on the leisure customer allows us to eliminate the significant costs associated with serving a wide variety of customers and to concentrate our product appeal on a customer base which is under-served by traditional airlines. We have consciously developed a business model which distinguishes us from the traditional airline approach:

(2)As of December 31, 2025, excludes three aircraft under operating lease which have been removed from service pending redelivery. Includes four aircraft under operating lease as of December 31, 2024, and December 31, 2023.

As of December 31, 2025, we are party to forward purchase agreements for 34 aircraft with 11 deliveries expected in 2026, 15 in 2027, and the remainder in 2028. The timing of these deliveries is based on management's best estimates and differs from the contract in place. Refer to Part I - Item 2. Properties for further detail regarding our aircraft fleet.

NETWORK

As of February 1, 2026, and including service announcements through that date, we were selling travel on 578 routes to 126 cities in 42 states. These include 39 routes scheduled to begin service in 2026.

Network growth in the future will continue to be affected by timing of aircraft deliveries, aircraft in heavy maintenance, airport construction and disruptions, trends in domestic, leisure air travel demand and other factors. We have identified over 1,400 incremental domestic nonstop routes as opportunities for future network growth, of which over 75 percent currently have no nonstop service. Our total number of origination cities and leisure destinations were 91 and 35, respectively, as of February 1, 2026, including announced routes.

Our unique model is predicated on expanding and contracting capacity to meet seasonal leisure travel demands.

The following table shows the number of leisure destinations and cities served as of the dates indicated (includes cities served seasonally):

	As of December 31,
	2025	2024	2023

TRENDS

Proposed Acquisition of Sun Country Airlines

In January 2026, we entered into an agreement to acquire Sun Country subject to satisfaction of customary closing conditions, including each company's receipt of certain shareholder approvals and regulatory reviews and approvals. See Item 1. Business - "Announced Acquisition of Sun Country Airlines." We believe the proposed transaction aligns with our long-term strategic objectives and is expected to enhance our network breadth, operational flexibility, and ability to respond to demand shifts, while supporting scheduled service, charter and cargo operations of both airlines. We believe the combination of our two financially strong leisure carriers in the U.S. will create benefits for customers, communities, employees, and partners by enhancing stability, expanding opportunities, and enabling continued investment and innovation. There are several risks associated with whether or not the transaction will close and also with respect to future operations if the transaction does close. See Item 1A. Risk Factors - "Risks Related to our Proposed Acquisition of Sun Country Airlines Holdings, Inc.” Future results of operations will be affected by the timing of regulatory approvals, integration considerations, transaction costs and other factors.

Business and Macroeconomic Conditions

Consumer confidence vacillated during 2025, which along with other macroeconomic and airline industry events, initially contributed to a general decline in consumer spending and, in particular, softened demand for domestic, leisure air travel. Although demand fluctuates, macroeconomic uncertainty persists, driven by factors such as trade policies and tariffs. These factors have impacted our fares, load factors, and profitability. Our results of operations may continue to be impacted while these conditions persist. We continue to monitor how these factors could impact our business and take steps to mitigate their effect on our business.

Aircraft Fuel

The cost of fuel is volatile, as it is subject to many economic and geopolitical factors we can neither control nor predict. Significant increases in fuel costs could materially affect our operating results and profitability. We have not sought to use financial derivative products to hedge our exposure to fuel price volatility, nor do we have any plans to do so in the future.

Elevated fuel costs in the future may impact our overall cost structure and operating results.

Boeing Agreement

We have signed an agreement and amendments with Boeing to purchase 50 newly manufactured 737 MAX aircraft with options to purchase up to an additional 80 737 MAX aircraft. We have taken delivery of 16 MAX aircraft from this order and all 16 aircraft are currently in revenue service. We believe this new aircraft purchase is complementary with our low-cost strategy based on our intent to retain ownership of the aircraft, the longer useful life for depreciation purposes, and expected fuel savings and operational reliability from the use of these new aircraft.

There continues to be regulatory focus on increasing quality control standards at Boeing and its suppliers with the aim of stabilizing aircraft production. These factors and the requirements for Boeing to obtain routine and necessary regulatory approvals could delay deliveries to us beyond management's current expectations. Although the contract provides for more deliveries, at this time, we currently expect eleven aircraft to be delivered to us in 2026. Further delays in aircraft deliveries will impact our ability to schedule additional growth in late 2026 and beyond.

Union Negotiations

The collective bargaining agreement with our pilots has been amendable since 2021. We and the International Brotherhood of Teamsters ("IBT") jointly requested the mediation services of the National Mediation Board in January 2023 to assist with the negotiations. The mediation process with the NMB is continuing. At this time, the announced acquisition of Sun Country has not changed the mediation process.

Separately from the ongoing collective bargaining agreement negotiations, to address retention and pilot pay issues and increase pilot staffing levels, effective in May 2023, we began accruing a retention bonus, with IBT's agreement, for pilots who continue employment with us until a new labor agreement is approved. The amount being accrued is 35 percent of current hourly pay rates, except for our first year first officers for whom the percentage is 82 percent, in each case, calculated at a minimum of 85 pay credit hours per month. Our implementation of the retention bonus has allowed us to effectively increase pay rates for our pilot team members (by way of the accrual of the retention bonus), add pilots through hiring and significantly slow attrition.

For the year ended December 31, 2025, we recorded estimated pilot retention bonus accruals of $89.8 million bringing the total accrual to $235.9 million at year end, including the related payroll taxes. The bonus will be paid to all pilots remaining employed with us after ratification of a new collective bargaining agreement.

Network Expansion

We have identified more than 1,400 incremental routes as opportunities for future network growth, with approximately 75 percent of these additional routes having no current nonstop service. Our ability to add significant numbers of new routes has been constrained in recent years by aircraft availability, flight crew staffing, high fuel costs, economic conditions and other factors. During 2026, we expect to continue focusing on the strategic utilization of our fleet, particularly during peak demand periods with only minimal scheduled service growth expected at this time. We anticipate that projected fleet growth after 2026 will provide additional flexibility to pursue network expansion opportunities.

Sunseeker Resort

In September 2025, we completed the sale of Sunseeker Resort. The sale aligns with our strategic focus on our core Airline operations.

Our Operating Expenses

A brief description of the items included in our operating expense line items follows.

Salaries and benefits expense includes wages, salaries, employee bonuses and pilot retention bonus accruals, as well as expenses associated with employee benefit plans, stock compensation expense related to equity grants, and employer payroll taxes. Salaries and benefits expense also includes such costs for Sunseeker Resort personnel through the sale of the Resort in September 2025.

Aircraft fuel expense includes the cost of aircraft fuel, fuel taxes, into plane fees and airport fuel flowage, storage or throughput fees.

Station operations expense includes the fees charged by airports for the use or lease of airport facilities and fees charged by third party vendors for ground handling services, commissary expenses, and other related services. Station operations expense also includes most of our irregular operations costs.

Depreciation and amortization expense includes the depreciation of all owned fixed assets, including aircraft and engines, Sunseeker Resort assets (until determined to be an asset held for sale in June 2025), and assets recorded in connection with finance leases. Also included is the amortization of heavy maintenance expenses on our aircraft and engines, which are capitalized under the deferral method of accounting and amortized as a component of depreciation and amortization expense over the estimated period until the next scheduled major maintenance event.

Maintenance and repairs expense includes all parts, materials and spares required to maintain our aircraft. Also included are fees for repairs performed by third party vendors.

Sales and marketing expense includes all advertising, promotional expenses, sponsorships, travel agent commissions, debit and credit card processing fees associated with the sale of scheduled service and air-related ancillary charges. Prior to the sale of Sunseeker Resort on September 4, 2025, sales and marketing expense also included costs related to advertising and marketing for the Resort, and credit card processing fees for Resort bookings.

Aircraft lease rentals expense consists of the cost of leasing aircraft under operating leases with third parties as well as the cost for sub-service which may be utilized in order to accommodate passengers in the event of operational disruption.

Other expense includes travel and training expenses for crews and ground personnel, facility lease expenses, professional fees, personal property taxes, information technology consulting, the cost of passenger liability insurance, aircraft hull insurance and all other insurance policies, excluding employee welfare insurance. Additionally, this expense includes gains and losses on disposals of aircraft and other equipment, and all other administrative and operational overhead expenses not included in other line items above.

Special charges for 2025 include expenses related to organizational restructuring driven by reduced air travel demand amid heightened macroeconomic uncertainty, accelerated amortization and disposal of software identified for redevelopment, costs related to the proposed acquisition of Sun Country Airlines, and charges related to the sale of Sunseeker Resort. Additional special charges in 2025, 2024, and 2023 include costs associated with the accelerated retirement of 24 airframes to align with planned 737 MAX aircraft deliveries, a ratification bonus for our flight attendants in 2024, an impairment charge in 2024 for Sunseeker Resort, as well as losses incurred at the Resort from hurricanes and other severe weather events, net of insurance recoveries.

RESULTS OF OPERATIONS

2025 compared to 2024

Operating Revenue

	Year Ended December 31,				Percent Change
Operating Revenues (in thousands)	2025		2024		YoY
Passenger	$	2,324,348	$	2,217,059	4.8	%
Third party products	143,188		142,128		0.7
Fixed fee contracts	77,647		80,660		(3.7)
Resort and other	61,396		72,742		(15.6)
Total operating revenues	$	2,606,579	$	2,512,589	3.7

Passenger revenue. Passenger revenue increased $107.3 million or 4.8 percent in 2025 compared to 2024, driven by a 10.5 percent increase in scheduled service passengers on a 13.1 percent increase in scheduled service departures. The increase in scheduled service passengers was offset by a 5.3 percent decrease in scheduled service total fare, which largely resulted from a 12.3 percent decline in average base fare due to demand softness in the industry. This decrease was partially offset by a 1.9 percent increase in average fare for air-related charges. Over the last year, revenues for air-related charges have been bolstered by sales of our Allegiant Extra product. Since December 31, 2024, we have configured an additional 31 aircraft with the extra legroom seating for our Allegiant Extra offering, bringing the total number to 87 aircraft as of December 31, 2025. The restoration of functionality around our third party bundled product offering, which began in late 2024, has also contributed to ancillary revenue increases over the last year.

Third party products revenue. Third party products revenue increased $1.1 million or 0.7 percent in 2025 compared to 2024. The increase was driven by a $3.8 million increase in revenue from sales of a third party travel insurance product, as well as a $1.4 million increase from sales of rental cars. These increases were partially offset by a $3.7 million decrease in the marketing component of co-brand revenue as certain bonus compensation was phased out in late 2024 and a decline in revenue from sales of hotel rooms.

Fixed fee contract revenue. Fixed fee contract revenue decreased $3.0 million or 3.7 percent in 2025 compared to 2024. While fixed fee departures were consistent year over year, revenue per departure declined due to operating a higher proportion of ad-hoc charter flights, which generated lower fuel pass through contributions (the fuel pass throughs being accounted for as revenue) driven by the decrease in average fuel prices year over year.

Resort and other revenue. Resort and other revenue decreased $11.3 million or 15.6 percent primarily due to the sale of Sunseeker Resort on September 4, 2025, resulting in approximately four fewer months of revenue included in 2025 compared to 2024.

Operating Expenses

The following table presents airline only operating unit costs on a per ASM basis, defined as Operating CASM, for the indicated periods. Excluding fuel on a per ASM basis provides management and investors the ability to measure and monitor our cost performance absent fuel price volatility. Both the cost and availability of fuel are subject to many economic and political factors beyond our control. Excluding special charges allows management and investors to better compare our airline unit costs with those of other airlines.

	Year Ended December 31,				Percent Change
Airline Unitized Costs (in cents)	2025		2024			YoY
Salaries and benefits	3.77	¢	4.06	¢		(7.1)	%
Aircraft fuel	2.99		3.31			(9.7)
Station operations	1.39		1.44			(3.5)
Depreciation and amortization	1.13		1.22			(7.4)
Maintenance and repairs	0.70		0.66			6.1
Sales and marketing	0.44		0.52			(15.4)
Aircraft lease rentals	0.17		0.12			41.7
Other	0.44		0.54			(18.5)
Special charges	0.21		0.24			(12.5)
Airline operating CASM	11.24	¢	12.11	¢		(7.2)
Airline operating CASM, excluding fuel	8.25	¢	8.80	¢		(6.3)
Airline operating CASM, excluding fuel and special charges	8.04	¢	8.56	¢		(6.1)

Airline operating CASM, excluding fuel and airline special charges. Airline operating CASM, excluding fuel and airline special charges, decreased by 6.1 percent to 8.04 ¢ from 8.56 ¢ in 2024. The primary driver of the CASM-ex decrease was a 12.6 percent increase in ASMs, as we grew into our existing infrastructure. In particular, we achieved the increased capacity with no increase to the average number of aircraft in service. A majority of expense line items were lower on a per ASM basis due in part to the increase in capacity. With limited ASM growth currently expected in 2026, CASM-ex is expected to increase to some extent during the year.

Salaries and benefits expense. Airline salaries and benefits expense increased $34.8 million or 4.5 percent in 2025 compared to 2024. The increase was primarily attributable to an increase in flight crew wages as the result of a 13.5 percent increase in total block hours flown resulting in part from our efforts to increase peak period utilization to pre-pandemic levels. Additionally, average flight crew wages increased due to an increase in average tenure. These increases were partially offset by savings from the organizational restructuring implemented in April 2025.

Salaries and benefits expense at Sunseeker Resort decreased by $21.6 million or 43.9 percent primarily due to the sale of the Resort on September 4, 2025, resulting in approximately four fewer months of expense included in 2025 compared to 2024. In addition, during the period prior to the sale, average full-time equivalent employees declined as certain functions were outsourced and staffing levels were strategically adjusted to align with operational needs.

Aircraft fuel expense. Aircraft fuel expense increased $12.0 million or 1.9 percent in 2025 compared to 2024. The increase was primarily driven by a 10.4 percent increase in fuel gallons consumed, attributable to a 12.6 percent increase in total system ASMs. This increase was partially offset by a 7.6 percent decrease in average fuel cost per gallon. Fuel efficiency improved by 1.9 percent year over year.

Station operations expense. Station operations expense increased $24.7 million or 9.1 percent in 2025 compared to 2024. The increase was primarily driven by a 12.7 percent year-over-year increase in total system departures that resulted in a corresponding rise in airport and landing fees, ground handling, deicing costs, and other stations-related expenses. In addition, station operations expense increased due to higher rent expense resulting from rate increases at multiple stations. These increases were partially offset by a reduction in passenger compensation expense resulting from fewer irregular operations events compared to the prior year as our controllable completion increased to 99.9 percent in 2025.

Depreciation and amortization expense. Airline depreciation and amortization expense increased $10.2 million or 4.4 percent in 2025 compared to 2024. This increase was primarily attributable to the addition of 12 new aircraft from our 737 MAX order, which were placed into service during 2025. Additionally, there was an increase in software amortization resulting from the airline's implementation of new enterprise resource planning systems throughout 2024 and 2025. These increases were partially offset by decreases in depreciation and heavy maintenance amortization associated with the retirement of six Airbus airframes during 2025.

Sunseeker Resort depreciation and amortization decreased by $19.3 million in 2025 compared to 2024. Depreciation of the Resort's assets ceased upon meeting held-for-sale classification criteria in June 2025. In addition, depreciation expense recorded during the first half of 2025 was lower than the same period in 2024 as a result of an impairment charge recorded in fourth quarter 2024 which reduced the carrying amount of Resort assets.

Maintenance and repairs expense. Maintenance and repairs expense increased by $24.5 million or 19.5 percent in 2025 compared to 2024, primarily as the result of the 12.6 percent increase in capacity. The increase was further driven by higher volumes of certain rotable part repairs and expendable consumption, as well as an increase in drop-in engine repairs during

2025. Maintenance and repairs expense was also impacted by tariffs and repairs to aircraft that we plan to return from operating leases.

Sales and marketing expense. Airline sales and marketing expense decreased by $4.2 million or 4.2 percent in 2025 compared to 2024 driven by a decrease in sponsorship expenses and a decrease in credit card processing fees. Notably, credit card processing fees decreased year over year, despite an increase in passenger revenue. We have made strategic efforts throughout the year to manage card processing fees, including adding a new payment option for our customers and migrating to a lower-fee card processor for our buy-on-board transactions.

Sunseeker Resort sales and marketing expense decreased by $2.7 million or 37.9 percent in 2025 compared to 2024 primarily due to the sale of Sunseeker Resort on September 4, 2025, resulting in approximately four fewer months of expense included in the year ended December 31, 2025 compared to 2024.

Aircraft lease rentals. Aircraft lease rental expense increased $12.9 million or 54.8 percent in 2025 compared to 2024. The increase is attributable to estimated lease return costs we began to accrue in second quarter 2025 for certain aircraft on operating leases related to redeliveries in 2025 and future years.

Other operating expense. Airline other operating expense decreased by $9.7 million or 9.5 percent in 2025 compared to 2024, reflecting reductions across several expense categories as a result of continued cost-management initiatives. These decreases were driven by lower corporate and crew travel, reduced crew administration and training costs, decreased legal expense, and lower corporate administrative costs during 2025. Other operating expenses were also impacted by gains and losses on sales of assets in each year.

Sunseeker Resort other operating expense decreased $14.3 million or 29.6 percent in 2025 compared to 2024 primarily due to the sale of Sunseeker Resort on September 4, 2025, resulting in approximately four fewer months of expense included in the year ended December 31, 2025 compared to 2024.

Special charges. Airline special charges were $43.5 million in 2025. Special charges included $8.0 million of accelerated depreciation on airframes identified for early retirement, $12.1 million related to corporate restructuring charges, $19.3 million related to accelerated amortization and disposal of certain internal-use software designated for redevelopment, and $4.1 million for initial professional services and other costs related to the proposed acquisition of Sun Country.

Sunseeker Resort special charges were $94.2 million in 2025, which primarily related to the sale of the Resort and the associated Aileron Golf Course. This included an asset write-down charge of $100.4 million, slightly offset by $2.1 million in other items and adjustments associated with the sale. Special charges also included further offsets of $4.2 million for net insurance recoveries received during 2025, related to previous damage from weather events. Refer to Note 15 in the consolidated financial statements for additional information on the sale of Sunseeker Resort.

Interest Expense and Income

Interest expense, net of interest income and capitalized interest, increased by $23.9 million or 35.6 percent, compared to 2024. The increase was primarily driven by a $27.8 million decrease in capitalized interest resulting from the delivery of 12 aircraft from our 737 MAX order since December 31, 2024, as interest on the related acquisition debt is no longer eligible for capitalization. In addition, we recognized $7.9 million of losses on debt extinguishment, primarily associated with the early repayment of various debt instruments during 2025, including $3.4 million related to the repayment of the Sunseeker construction loan, all of which are reflected in interest expense. These increases were partially offset by a $14.1 million or 9.0 percent decrease in interest expense attributable to a lower average outstanding debt balance year over year and a reduction in the weighted‑average variable interest rate on our debt compared to 2024.

Income taxes

We recorded a $10.2 million tax benefit in 2025 compared to a $68.2 million tax benefit in 2024. The effective tax rates for 2025 and 2024 differed from the statutory federal income tax rate of 21.0 percent primarily due to state income taxes and the impact of permanent tax differences.

2024 compared to 2023

The comparison of our 2024 results to 2023 results is included in our Annual Report on Form 10-K for the year ended December 31, 2024, under Part II Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations.

(1)Defined as scheduled service revenue divided by revenue passenger miles

(2)Various components of this measure do not have a direct correlation to ASMs. These figures are provided on a per ASM basis so as to facilitate comparisons with airlines reporting revenues on a per ASM basis.

(3)Reflects division of passenger revenue between scheduled service and air-related charges in our booking path.

The following terms used in this section and elsewhere in this annual report have the meanings indicated below:

“Available seat miles” or “ASMs” represents the number of seats available for passengers multiplied by the number of miles the seats are flown.

“Average fuel cost per gallon” represents total aircraft fuel expense for our total system or scheduled service (as applicable) divided by the total number of fuel gallons consumed in our total system or scheduled service.

“Average stage length” represents the average number of miles flown per flight.

“Block hours” represents the number of hours during which the aircraft is in revenue service, measured from the time of gate departure until the time of gate arrival at the destination.

“Load factor” represents the percentage of aircraft seating capacity utilized (revenue passenger miles divided by available seat miles).

“Airline operating expense per ASM” or “CASM” represents airline only operating expenses excluding Sunseeker divided by total system available seat miles.

“Airline operating CASM, excluding fuel and special charges” represents airline only operating expenses excluding Sunseeker, less aircraft fuel expense and special charges, divided by total system available seat miles. This statistic provides management and investors the ability to measure and monitor our airline cost performance absent fuel price volatility. Both the cost and availability of fuel are subject to many economic and political factors and therefore are beyond our control.

“Passengers” represents the total number of passengers flown on all flight segments.

“Revenue passenger miles” or “RPMs” represents the number of miles flown by revenue passengers.

“Total passenger revenue per ASM” or “TRASM” represents total passenger revenue divided by scheduled service available seat miles.

LIQUIDITY AND CAPITAL RESOURCES

Current liquidity

Cash, cash equivalents and investment securities (short-term and long-term) increased to $838.5 million at December 31, 2025, from $832.9 million at December 31, 2024. Investment securities represent highly liquid marketable securities which are available-for-sale.

As of December 31, 2025, we had $250.0 million of undrawn capacity under revolving credit facilities, plus another $25.1 million of undrawn capacity under a PDP financing facility.

Restricted cash represents escrowed funds under fixed fee contracts and cash collateral against letters of credit required by hotel properties for guaranteed room availability, airports and certain other parties. Under our fixed fee flying contracts, we require our customers to prepay for flights to be provided by us. The prepayments are escrowed until the flight is completed and are recorded as restricted cash with a corresponding amount reflected as air traffic liability.

Our operating cash flows and long-term debt borrowing have allowed us to invest in our fleet renewal. Future capital needs are primarily for the acquisition of additional aircraft, including our existing aircraft commitments, and for the proposed acquisition of Sun Country and related expenditures.

Our share repurchase authority at December 31, 2025 is $64.7 million. During the first quarter of 2025, we made $11.0 million of open market share repurchases. We did not repurchase any shares on the open market during the second, third, or fourth quarters of 2025. We have indefinitely suspended our quarterly cash dividend in anticipation of upcoming capital needs related to our fleet investments.

We believe we have more than adequate liquidity resources through our cash, cash equivalents and short term investment balances, financing commitments, our undrawn capacity under existing credit facilities, operating cash flows and anticipated access to liquidity, to meet our current contractual obligations and remain in compliance with the debt covenants in our existing financing agreements for the next 12 months. We will continue to consider raising funds through debt financing as needed to fund capital expenditures.

Debt

Our debt and finance lease obligations balance, without reduction for related issuance costs, decreased from $2.08 billion as of December 31, 2024 to $1.82 billion as of December 31, 2025. During 2025, we borrowed $638.9 million of which $589.0 million was secured by aircraft and aircraft related assets. Additionally, we made principal payments (scheduled principal payments and prepayments) totaling $906.3 million, including $390.2 million of the principal amount of facilities secured by aircraft and aircraft-related assets, $147.0 million of the principal amount of our Senior Secured Notes, a $100.0 million prepayment of the remaining principal balance of our Sunseeker construction loan, and $263.1 million related to our unsecured debt and PDP financing.

As of December 31, 2025, approximately 58.8 percent of our debt and finance lease obligations are fixed-rate.

Sources and Uses of Cash

Operating Activities.

During 2025, we generated cash flows from operations of $389.8 million, compared to $338.5 million during 2024.

Our operating cash flows are impacted by the following factors:

Advance Ticket Sales. Tickets for air travel are typically purchased in advance of the travel date. When we receive a cash payment at the time of booking, we record the cash received as deferred revenue in air traffic liability. When the flight is flown, we recognize the liability from air traffic liability into revenue. Due to the seasonal nature of our operations, our air traffic liability balances will fluctuate in line with our peak flying seasons.

Salaries and Benefits. Salaries and benefits expense represents our single largest expense and has increased considerably in recent years. Cash payments for our salaries and benefits expense are typically made in the period that they are incurred with the exception of our pilot retention bonus, which will be paid to all pilots after ratification of a new collective bargaining agreement. At December 31, 2025 and 2024, we have recorded a liability of $235.9 million and $146.1 million, respectively, in relation to the pilot retention bonus, including related payroll taxes.

Fuel. Fuel expense is our second largest expense. The market price for jet fuel is volatile, which can impact the comparability of our periodic cash flows from operations. During 2025, we increased our year over year flying capacity by 12.6 percent, which led to a 10.4 percent increase in fuel gallons consumed and a $12.0 million increase in fuel expense.
