ITEM 1. BUSINESS

General

Through SkyWest Airlines, we offer scheduled passenger service to destinations in the United States, Canada and Mexico. Substantially all of our flights are operated as United Express, Delta Connection, American Eagle or Alaska Airlines flights under code-share agreements with United, Delta, American or Alaska, respectively. Code-share agreement are commercial agreements between airlines that, among other things, allow one airline to use another airline’s flight designator codes on its flights. As of December 31, 2024, we offered approximately 2,190 daily departures, of which approximately 890 were United Express flights, 700 were Delta Connection flights, 380 were American Eagle flights and 220 were Alaska Airlines flights.

We generally provide regional flying to our major airline partners under long-term, fixed-fee, code-share agreements. Under these fixed-fee agreements (commonly referred to as “capacity purchase agreements”), our major airline partners generally pay us fixed rates for operating the aircraft primarily based on the number of completed flights, flight time and the number of aircraft under contract. The major airline partners either directly pay for or reimburse us for specified direct operating expenses, including fuel expenses. Our operations are conducted principally at airports that support our major airline partners’ route networks, including Chicago (O’Hare), Dallas, Denver, Detroit, Houston, Los Angeles, Minneapolis, Phoenix, Salt Lake City, San Francisco and Seattle.

We conduct our code-share operations with our major airline partners pursuant to various code-share agreements described under the heading “Code-Share Agreements” below.

Fleet

SkyWest has been flying since 1972. During our long operating history, we have developed an industry-leading reputation for providing quality regional airline service. As of December 31, 2024, our fleet consisted of aircraft manufactured by Embraer S.A. (“Embraer”) and MHI RJ Aviation ULC, formerly known as Bombardier Aerospace (“Bombardier”), including the E175 regional jet aircraft (“E175”), the Canadair CRJ900 regional jet aircraft (“CRJ900”), the Canadair CRJ700 regional jet aircraft (“CRJ700”), including a 50-seat configuration of the CRJ700 aircraft, commonly referred to as a “CRJ550” and the Canadair CRJ200 regional jet aircraft (“CRJ200”). As of December 31, 2024, we had 624 total aircraft in our fleet, including 492 aircraft in scheduled service or under contract pursuant to our code-share agreements, summarized as follows:

Bombardier and Embraer are the primary manufacturers of regional jets operated in the United States and offer many of the amenities of larger commercial jet aircraft, including flight attendant service, a stand-up cabin, overhead and under seat storage, lavatories and in-flight snack and beverage service. The Bombardier CRJ900, CRJ700 and CRJ550 aircraft and the Embraer E175 aircraft we operate are configured with a first-class seating section. The Bombardier CRJ200 aircraft we operate are configured with single-class seating. The speed of Bombardier and Embraer regional jets is comparable to larger aircraft operated by major airlines, and they have a range of approximately 1,600 miles and 2,100 miles, respectively. As of December 31, 2024, our fleet seat configuration by aircraft type is summarized as follows:

SkyWest Leasing

SkyWest Leasing is a reportable segment that includes revenue associated with our financing of new aircraft with debt under our capacity purchase agreements, currently consisting of our E175 aircraft, and the depreciation and interest expense of our E175 aircraft. The SkyWest Leasing segment additionally includes the revenue and expense from leasing aircraft and engines to third parties. The SkyWest Leasing segment’s total assets and capital expenditures include the acquired E175 aircraft and aircraft and engines leased to third parties.

As of December 31, 2024, SkyWest Leasing leased 35 CRJ700 aircraft, five CRJ900 aircraft and regional jet aircraft engines to third parties.

SkyWest Charter (SWC)

In 2022, we formed a new subsidiary, SWC, which began operations in 2023. SWC offers on-demand charter service using CRJ200 aircraft in a 30-seat configuration. As of December 31, 2024, SWC had 18 aircraft available for on-demand charter service.

Competition and Economic Conditions

The airline industry is highly competitive. We compete principally with other regional airlines. Our operations extend throughout most major geographic markets in the United States. Our competition includes, therefore, nearly every other domestic regional airline. Our primary competitors include Air Wisconsin Airlines Corporation (“Air Wisconsin”); Endeavor Air, Inc. (“Endeavor”) (owned by Delta); Envoy Air Inc. (“Envoy”), PSA Airlines, Inc. (“PSA”) and Piedmont Airlines (“Piedmont”) (Envoy, PSA and Piedmont are owned by American); Horizon Air Industries, Inc. (“Horizon”) (owned by Alaska Air Group, Inc.); GoJet Airlines, LLC (“GoJet”); Mesa Air Group, Inc. (“Mesa”); and Republic Airways Holdings Inc. (“Republic”). Major airlines typically award code-share flying agreements to regional airlines based primarily upon the following criteria: ability to fly contracted schedules, availability of labor resources, including pilots, low operating cost, financial resources, geographical infrastructure, overall customer service levels relating to on-time arrival and flight completion percentages and the overall image of the regional airline. Additionally, each major airline may be limited in the number and type of regional aircraft it may use in its network due to agreements the major airline has with its own labor groups, commonly referred to in the industry as “scope limitations.” Given our major airline partners’ scope limitations, we currently do not operate a regional aircraft configured with more than 76 seats.

The principal competitive factors for regional airline code-share agreements include labor resources, code-share agreement terms, reliable flight operations, operating cost structure, ability to finance new aircraft, certification to operate certain aircraft types and geographical infrastructure supporting markets and routes served.

Our operations represent the largest regional airline operations in the United States. However, regional carriers owned by major airlines may have access to greater resources than we do through their parent companies.

Generally, the airline industry is sensitive to changes in general economic conditions. Economic downturns, combined with competitive pressures, have contributed to a number of reorganizations, bankruptcies, liquidations and business combinations among major and regional carriers. The effect of economic downturns may be somewhat mitigated by our predominantly contract-based flying agreements. If, however, any of our major airline partners experience a prolonged decline in the number of passengers or are negatively affected by low ticket prices or high fuel prices, they may seek rate reductions in future code-share agreements, or materially reduce scheduled flights in order to reduce their costs. In addition, adverse weather conditions can impact our ability to complete scheduled flights and can have a negative impact on our operations and financial condition. Also, major airline scope limitations may restrict growth opportunities for the regional carriers. Additionally, attrition of our pilots or other workgroups may reduce our flying schedules and have a negative impact on our operations and financial condition.

Impact of Regional Airline Captain Availability on Production

As passenger demand in the airline industry recovered from the COVID-19 pandemic in 2020, the number of regional airline captains and first officers hired by major airlines and low-cost carriers significantly increased. As a result, we experienced a high level of captain and first officer attrition during 2022 and 2023. During 2024, captain attrition began to ease. Sequential fluctuations in the number of completed departures and completed block hours from 2022 to 2024 were primarily driven by available captains.

Capacity and flight schedule impact. We completed the following number of flights and related block hours in 2024, 2023 and 2022:

Liquidity

At December 31, 2024, we had $876.7 million in total available liquidity, consisting of $801.6 million in cash, cash equivalents and marketable securities, and $75.1 million available for borrowing under our line of credit.

Industry Overview

Majors, Low-Cost Carriers and Regional Airlines

The airline industry in the United States has traditionally been comprised of several major airlines, including Alaska, American, Delta and United. The major airlines offer scheduled flights to most major U.S. cities, numerous smaller U.S. cities, and cities throughout the world through a hub-and-spoke network.

Low-cost carriers, such as Southwest Airlines Co. (“Southwest”), JetBlue Airways Corporation (“JetBlue”), Spirit Airlines, Inc. (“Spirit”), Allegiant Travel Company (“Allegiant”), Frontier Group Holdings, Inc. (“Frontier”) and Breeze Aviation Group, Inc. (“Breeze”) generally have lower cost structures than major airlines, which permits them to offer flights to and from many of the same markets as the major airlines, but at lower prices. Low-cost carriers typically operate using a point-to-point network strategy, rather than a hub-and-spoke network.

Regional airlines, including SkyWest, typically operate smaller aircraft on shorter routes than major and low-cost carriers. Several regional airlines, including Endeavor, Envoy, Horizon, Piedmont and PSA, are wholly-owned subsidiaries of major airlines.

Regional airlines generally do not try to establish an independent route system and compete with the major airlines. Rather, regional airlines typically enter into agreements with one or more major airlines, pursuant to which the regional airline agrees to use its smaller, lower-cost aircraft to carry passengers booked and ticketed by the major airline between a hub of the major airline and a smaller outlying city. In exchange for such services, the major airline pays the regional airline either fixed fees to operate the flight, termed “capacity purchase agreement,” or “flying contract,” or the regional airline receives a percentage of applicable passenger ticket revenues on designated flights operated by the regional airline, termed “prorate agreement” as described in more detail below.

Code-Share Agreements

Regional airlines generally enter into code-share agreements with major airlines, pursuant to which the regional airline is authorized to use the major airline’s two-letter flight designator codes to identify the regional airline’s flights and fares in the central reservation systems, to paint its aircraft with the colors and/or logos of the major airline and to market and advertise its status as a carrier for the major airline. Code-share agreements also generally obligate the major airline to provide services such as reservations, ticketing, ground support and gate access to the regional airline, and the major airline often coordinates marketing, advertising and other promotional efforts. In exchange, the regional airline provides a designated number of low-capacity (usually between 50 and 76 seats) flights between larger airports served by the major airline and surrounding cities, usually in lower-volume markets. The financial arrangements between the

regional airlines and their code-share partners usually involve either capacity purchase agreements or prorate agreements as explained below:

We have code-share agreements with United, Delta, American and Alaska. During the year ended December 31, 2024, approximately 87% of our flying agreements revenue related to capacity purchase agreement flights, where United, Delta, American and Alaska controlled scheduling, ticketing, pricing, and seat inventories. The remainder of our flying agreements revenue during the year ended December 31, 2024, related to prorate flights for United or Delta, where we controlled scheduling, pricing and seat inventories on certain prorate routes, and shared passenger fares with United or Delta according to prorate formulas and SWC on-demand charter flights. The routes placed under our prorate agreements typically include flight service between one of our partners’ hub cities and a city not served under our capacity purchase agreements.

Under our capacity purchase agreements, our major airline partners compensate us for our costs of owning the aircraft on a monthly basis. The aircraft compensation structure varies by agreement but is intended to cover either our aircraft principal and interest debt service costs or our aircraft depreciation and interest expense while the aircraft is under contract. The number of aircraft under our capacity purchase agreements and our prorate agreements as of December 31, 2024 is reflected in the summary below. The following summaries of our code-share agreements with our major airline partners do not purport to be complete and are qualified in their entirety by reference to the applicable agreement.

United Express Agreements

Delta Connection Agreements

​

American Capacity Purchase Agreement

​

Alaska Capacity Purchase Agreement

In addition to the aircraft operating under the respective agreements outlined above, we have agreed with our major airline partners to place additional aircraft under capacity purchase agreements as summarized below. We are coordinating with our major airline partners to optimize the timing of upcoming fleet deliveries and the delivery timing referenced below is subject to change.

United Express Agreements

We and United are parties to two United Express agreements: a United Express agreement to operate certain CRJ200 aircraft and CRJ700 aircraft, and a United Express agreement to operate E175 aircraft and CRJ550 aircraft (collectively, the “United Express Agreements”).

The United Express Agreements have a latest scheduled termination date in 2033. The United Express Agreements are subject to early termination in various circumstances including:

Delta Connection Agreements

We and Delta are parties to a Delta Connection Agreement (the “Delta Connection Agreement”), pursuant to which we provide contract flight services for Delta.

The Delta Connection Agreement has a latest scheduled termination date of 2034. The Delta Connection Agreement is subject to early termination in various circumstances including:

American Agreement

We and American are parties to a Capacity Purchase Agreement (the “American Agreement”) for the operation of E175 and CRJ700 aircraft. The American Agreement has a latest scheduled termination date of 2032 and is subject to early termination in various circumstances including:

Alaska Agreement

We and Alaska are parties to a capacity purchase agreement (the “Alaska Agreement”) for the operation of E175 aircraft. The Alaska Agreement has a latest scheduled termination date of 2034 and is subject to early termination in various circumstances including:

Training and Aircraft Maintenance

We provide substantially all training to our crew members and maintenance personnel at our training facilities. Our employees perform routine airframe and engine maintenance along with periodic inspections of equipment at our maintenance facilities. We also use third-party vendors for certain airframe and engine maintenance work.

Fuel

Our capacity purchase agreements with United, Delta, American and Alaska require the respective major airline partner to pay for fuel costs, either directly to the fuel vendor or to reimburse us for the fuel costs we incur under those agreements, thereby reducing our exposure to fuel price fluctuations. Under our prorate agreements with United and Delta, we are responsible for the costs to operate the flights, including fuel costs, and therefore we are exposed to fuel price fluctuations for flights operated under our prorate agreements. During the year ended December 31, 2024, our major airline partners purchased the majority of the fuel for our aircraft flying under their respective capacity purchase agreements directly from their fuel vendors or, when applicable, reimbursed us for the fuel costs we incurred under the capacity purchase agreements. Historically, we have not experienced sustained material problems with the availability of fuel and believe we will be able to obtain fuel in quantities sufficient to meet our existing and anticipated future requirements at competitive prices. We typically purchase fuel from third-party suppliers for our prorate agreements. A substantial increase in the price of jet fuel for flights we operate under our prorate agreements, or the lack of adequate fuel supplies in the future, could have a material adverse effect on our business, financial condition, results of operations or liquidity.

Human Capital Resources

Employee Profile

As of December 31, 2024, we employed 14,610 total employees, consisting of 5,048 pilots, 4,612 flight attendants, 1,716 airport operations personnel, 1,463 maintenance technicians, 887 other maintenance personnel, 198 dispatchers and 686 operational support and administrative personnel. Our total employees at December 31, 2024, included 1,734 part-time employees. As of December 31, 2024, all our employees are employed by SkyWest Airlines or to a limited extent, by SWC. Certain SkyWest Airlines employees also provide administrative support to the SkyWest Leasing segment. Approximately 89.2% of these employees were represented by in-house labor associations that have entered into collective bargaining agreements regarding employee compensation and work rules. None of these employees are currently represented by an outside union. Outside union organizing efforts among our employees do occur from time to time and may continue in the future. If unionization efforts are successful, we may be subjected to increased risks of work interruption or stoppage; and/or we may be limited in our ability to communicate with our employees, which would negatively impact our culture and working relationship with our employees. Additionally, an outside union may limit our ability to increase employee wages to market rates in a timely manner which could result in low employee job satisfaction and increased employee attrition. SkyWest Airlines has never experienced a work stoppage due to a strike or other labor dispute, and we consider our relationships with our employees to be good.

Our relations with labor are governed by the Railway Labor Act (the “RLA”), the federal law governing labor relations between air carriers and their employees. Under the RLA, a collective bargaining agreement between an airline and a labor representative does not expire, but instead becomes amendable as of a stated date. If either party wishes to modify the terms of any such agreement, it must notify the other party in the manner prescribed by the RLA and/or described in the agreement. After receipt of such notice, the parties must meet for direct negotiations, and if no agreement is reached, either party may request the National Mediation Board (“NMB”) to initiate a process including mediation, arbitration, and a potential “cooling off” period that must be followed before either party may engage in “self-help.” “Self-help” includes, among other things, a strike by the representative or the imposition of proposed changes to the collective bargaining agreement by the airline. If the NMB believes that self-help has the risk “substantially to interrupt interstate commerce to a degree such as to deprive any section of the country of essential transportation service,” it may recommend that the President establish a Presidential Emergency Board (“PEB”). The PEB would hear testimony and make a recommendation regarding how to resolve the outstanding issues.

We respect all employees’ legal rights, including the rights to free association and collective bargaining. This includes the right to decide whether to be represented by a union. Under the RLA, employees have the right to decide whether they wish to be represented by a union. They also have the right to reject union representation.

In September 2022, we entered into a collective bargaining agreement with our pilots, increasing the pay rates for pilots. Additionally, during the years ended December 31, 2023 and December 31, 2022, we amended our capacity purchase agreements with our major airline partners which resulted in higher compensation as a result of our increased labor costs. We have also worked with our other operational workgroups to secure significant increases in each of their pay scales and bonuses, including a 35% increase in starting pay for SkyWest flight attendants in 2023.

Culture

At SkyWest our people are our most valued assets, and the success of our business is dependent on having a collaborative, engaged and effective workforce. We respect every individual's quality of life and are committed to promoting integrity and trust in all we do. We strive to be the partner of choice and employer of choice.

Health & Safety

Safety is the primary focus and foundation of our culture with our first guiding principle being Health and Safety First. We expect our employees to think, plan, communicate and act appropriately to prevent injury, illness or harm to themselves, fellow employees, passengers and aircraft. SkyWest’s Safety Management System (SMS) integrates an intentional safety culture into every work group and every employee process from new hire through retirement, focusing on industry-best practices in safety competencies and behaviors. Training is required for every SkyWest employee, regardless of position.

SkyWest’s SMS is designed to identify, track, and help mitigate potential safety risks before an incident or accident occurs. Employees are encouraged to participate in our voluntary programs to report potential safety concerns or violations to reduce safety risk, including, but not limited to our Aviation Safety Action Program and Safety Concern Report.

Attracting, Developing and Retaining Talent

Recruitment Strategies. We strive to be the employer of choice for aviation professionals pursuing a career in the regional airline industry and we continually update our recruiting strategies to attract quality aviation professionals. We adapt our recruitment efforts based on the supply of eligible aviation professionals and our outlook for anticipated future flight schedules. Our recruiting focus generally targets key aviation technical roles, especially pilots and mechanics. We seek qualified individuals through publishing positions on both internal and external career websites, supporting professional development leads, investment in targeted advertising, social media outreach, employee referrals and relationships with community-based organizations and educational institutions.

School Partnerships and Development. We maintain relationships with numerous flight schools and educational institutions across the country that are focused on developing the next generation of aviation professionals. We have also developed relationships with numerous aviation mechanic schools. We typically recruit pilots and maintenance technicians that have completed required coursework from an accredited flight or maintenance school, respectively, and have obtained other applicable certifications. We also provide other programs to enhance our recruiting efforts towards individuals who are in process of completing their training, including a Pilot Pathway Program and an Aviation Maintenance Technician (AMT) Pathway Program.

Ongoing Training and Retention. SkyWest invests in retaining its professionals by providing a range of talent development opportunities, including mandatory compliance training, new hire training and general professional development, as well as engaging in the training of leaders through leadership development courses. Our training programs include full-motion flight simulators for pilots, on-the-job training for technicians, and cabin trainers for flight attendants. We also reinforce our guiding principles, including but not limited to, health and safety, personal and corporate integrity, excellent service and quality, and respect and teamwork through our training and development programs, as well as through our employee appreciation and recognition programs.

Diversity & Inclusion

Our approach is to hire the best qualified individuals, regardless of race, religion, gender, national origin, disability, sexual orientation or similar classifications. As of December 31, 2024, approximately 42% and 32% of our workforce were women and people of color, respectively. We believe every employee brings unique education, skills and life experiences to SkyWest that supplement our ability to achieve our commitment to excellence and to our customers and passengers. As part of SkyWest’s commitment to hire the best qualified individuals, we have:

Total Rewards

SkyWest Airlines operates in a customer-focused, team-based environment and provides opportunities for dedicated individuals to develop their career while receiving competitive compensation, benefits and rewards. Our employees receive several compensation benefits, including but not limited to:

Employee Reporting

Our Code of Conduct contains general guidelines for conducting business in an ethical manner. We are committed to a working environment that is safe and supports open and honest communication. We have established a reporting system for any SkyWest employee to report a violation of Company policy including harassment, discrimination, drug and alcohol use, questionable financial practice, or a breach involving safety or security. A general grievance may also be filed even if an employee has already utilized their chain of command or chooses to remain anonymous. Our Code of Conduct also forbids retaliation against any employee who, in good faith, reports a suspected

violation of law or policy. Reports can be filed using a toll-free ethics and grievance hotline or by using an online reporting system on SkyWest’s intranet.

Government Regulation

All interstate air carriers, including SkyWest, are subject to regulation by the U.S. Department of Transportation (the “DOT”), the U.S. Federal Aviation Administration (the “FAA”) and other governmental agencies. Regulations promulgated by the DOT primarily relate to economic aspects of air service. The FAA requires operating, airworthiness and other certificates; approval of personnel who may engage in flight, maintenance or operating activities; record-keeping procedures in accordance with FAA requirements; and FAA approval of flight training and retraining programs. Generally, governmental agencies enforce their regulations through, among other methods, certifications, which are necessary for the continued operations of SkyWest, and proceedings, which can result in civil or criminal penalties or revocation of operating authority. The FAA can also issue maintenance directives and other mandatory orders relating to, among other things, grounding of aircraft, inspection of aircraft, installation of new safety-related items and the mandatory removal and replacement of aircraft parts.

We believe SkyWest complies, in all material respects, with FAA regulations and holds all operating and airworthiness certificates and licenses which are necessary to conduct our operations. We maintain current certifications and otherwise comply with the laws, rules and regulations to which we are subject. Our flight operations, maintenance programs, recordkeeping and training programs are conducted under FAA approved procedures. All air carriers operating in the United States are required to comply with federal laws and regulations pertaining to noise abatement and engine emissions. All such air carriers are also subject to certain provisions of the Federal Communications Act of 1934, as amended, because of their extensive use of radio and other communication facilities. SkyWest is also subject to certain federal and state laws relating to protection of the environment, labor relations and equal employment opportunity. We believe SkyWest complies, in all material respects, with these laws and regulations.

Environmental Matters

We are subject to various federal, state, local and foreign laws and regulations relating to environmental protection matters. These laws and regulations govern such matters as environmental reporting, storage and disposal of materials and chemicals and aircraft noise. We are, and expect in the future to be, involved in various environmental matters and conditions at, or related to, our properties. We are not currently subject to any environmental cleanup orders or actions imposed by regulatory authorities. We are not aware of any active material environmental investigations related to our assets or properties.

As the largest regional airline in the United States, we remain committed to working with our major airline partners to lower our environmental footprint while continuing to offer the best service to our customers and the communities we serve. Our largest source of emissions and environmental impact comes from utilizing jet fuel on flights operated under our code-share agreements with our major airline partners. Under our capacity purchase agreements, our major airline partners purchase the aircraft fuel we consume, select the aircraft type we operate, and set flight schedules, all of which are variables which impact fuel consumption efficiencies. During 2024, we produced approximately 5.6 million metric tons of CO₂e from fuel burned, using industry emissions factors, on flights we operated under our code-share agreements. We are largely dependent on direction from our major airline partners regarding long-term fuel saving initiatives such as engine innovations reducing fuel consumption, use of sustainable alternative fuels, carbon sequestration programs, air traffic flow routing efficiencies, and similar initiatives. Each of our major airline partners may pursue alternative strategies and goals to reduce carbon emissions on flights we operate under our code-share agreements that may impact the rate at which we are able to reduce our carbon emissions, if at all. We anticipate our major airline partners will take responsibility for carbon emissions incurred on our contract flights.

Our board of directors has oversight of our environment-related performance. Through software and training, we heavily monitor and manage our fuel trends and fuel consumption which leads to better fuel management and reductions in emissions. When possible, we conserve fuel burned by utilizing single engine taxi procedures, improving the efficiency of aircraft routing, using performance-based navigation procedures to reduce track miles, and using ground power when parked at the gate. Additionally, we collaborate with aircraft and engine manufacturers and our major airline partners regarding innovations and emerging technologies that could improve fuel efficiencies and minimize environmental impact. We are also collaborating with our major airline partners and fuel providers regarding long-term

opportunities to use sustainable aviation fuel in the future. We are evaluating opportunities to increase the number of electric powered ground equipment, including tugs and pushbacks used at airports where we provide ramp services. We participate with our major airline partners in recycling programs, and we have implemented recycling initiatives in our facilities to reduce the amount of paper, plastic and other recyclables going to landfills. We have worked aggressively to reduce our reliance on paper manuals, further eliminating unnecessary waste while increasing efficiencies.

We have entered into a strategic partnership with Eve UAM, LLC (“Eve UAM”), an Embraer company, to develop a network of deployment for Eve UAM’s electric vertical takeoff and landing (“eVTOL”) aircraft. Subject to an agreement of key commercial terms, this partnership includes the option for SkyWest to purchase up to 100 eVTOL aircraft.

Safety and Security

We are committed to the safety and security of our passengers and employees. We have taken many steps, both voluntarily and as mandated by governmental authorities, to increase the safety and security of our operations. Some of the safety and security measures we have taken with our major airline partners include: aircraft security and surveillance, aircraft cleaning procedures, positive bag matching procedures, enhanced passenger and baggage screening and search procedures and securing of cockpit doors. We are committed to complying with future safety and security requirements.

Insurance

We maintain insurance policies we believe are of types customary in the industry and in amounts we believe are adequate to protect against material loss. These policies principally provide coverage for public liability, passenger liability, baggage and cargo liability, property damage, including coverage for loss or damage to our flight equipment, and workers’ compensation insurance.

Seasonality

Our results of operations for any interim period are not necessarily indicative of those for the entire year, in part because the airline industry is subject to seasonal fluctuations and changes in general economic conditions. Our operations are somewhat favorably affected by pleasure travel on our prorate routes, historically contributing to increased travel in the summer months, and are unfavorably affected by decreased business travel during the months from November through January and by inclement weather which can result in cancelled flights, principally during the winter months. Additionally, a significant portion of our capacity purchase agreements are based on completing flights and we typically have more scheduled flights during the summer months. We generally experience a significantly higher number of weather cancellations during the winter months, which negatively impacts our revenue during such months.

ITEM 1A. RISK FACTORS

In addition to factors discussed elsewhere in this Report, the following are important risks which could adversely affect our future results. Additional risks and uncertainties not presently known to us or that we currently do not deem material may also impair our business operations. If any of the risks we describe below occur, or if any

unforeseen risk develops, our operating results may suffer, our financial condition may deteriorate, the trading price of our common stock may decline and investors could lose all or part of their investment in us.

Risks That May Disrupt Our Operations

We may experience disruption in service due to delays from key third-party aircraft maintenance service providers.

We rely on third-party vendors for a variety of services, parts and functions critical to our business, particularly related to airframe and engine maintenance and repair. Even though we strive to formalize agreements with key vendors that define expected service levels and availability of parts, our use of outside vendors, including, but not limited to aircraft maintenance, ground handling, fueling, telecommunication systems and information technology services, increases our exposure to several risks. Current economic conditions have resulted in delays from third-party service providers for spare aircraft parts and third-party service providers have recently experienced challenges in retaining trained technicians. Delays from third-party service providers could negatively impact our ability to timely maintain our fleet currently in service. Additionally, as our captain attrition levels eased during 2024, our plans for 2025 include bringing certain CRJ aircraft out of storage and placing such aircraft into service. Delays in receiving spare parts and/or outsourced maintenance services could delay our efforts to place stored aircraft back into service.

Further, in the event that one or more vendors experiences labor shortages, aircraft part shortages, goes into bankruptcy, ceases operation or fails to perform as promised, replacement services may not be readily available at competitive rates, or at all. If one of our vendors fails to perform adequately, we may experience increased costs, delays, maintenance issues, safety issues or negative public perception of our airline. Vendor bankruptcies, unionization, regulatory compliance issues or significant changes in the competitive marketplace among suppliers could adversely affect vendor services or force us to renegotiate existing agreements on less favorable terms. These events could result in disruptions in our operations or increases in our cost structure.

We have experienced, and may continue to experience, difficulty in retaining and upgrading qualified pilots.

Our operations rely on recruiting and training qualified pilots. FAA regulations regarding personnel certification and qualifications have limited, and along with potential future changes in FAA regulations, could continue to limit, the number of qualified new entrants that we could hire. In the event we are unable to hire qualified pilots, we may be unable to operate requested flight schedules under our capacity purchase agreements, which could result in a reduction in revenue and operating inefficiencies, such as incremental new-hire training costs, and our business and financial condition could be adversely affected.

Our operations also rely on retaining qualified pilots, including captains and first officers. Our pilots may seek employment at major airlines, low-cost carriers or cargo carriers, which generally offer higher salaries and more extensive benefit programs than regional airlines. In recent years, we have experienced elevated levels of pilot attrition, particularly attrition of our captains. Recent shortages of captains caused a sequential reduction in our annual block hours in 2022 and 2023. Although captain attrition levels eased in 2024, future elevated pilot attrition levels could constrain our flight schedules. Operating at reduced flying schedules results in operating inefficiencies which negatively impacts our financial results. If we request our major airline partners to reduce our flight schedules due to pilot or other labor shortages, our major airline partners may seek to enforce financial penalties or reduce the compensation otherwise payable to us under our capacity purchase agreements, which would likely have a negative impact on our revenues and adversely impact our financial condition.

We have experienced, and may continue to experience, difficulty recruiting and retaining other operational personnel.

In addition to pilots, our operations rely on recruiting and retaining other qualified personnel, including, but not limited to, flight attendants, maintenance technicians, dispatch personnel, crew support and other operational personnel. Our operational personnel may seek employment at major airlines, which generally offer higher salaries and more extensive benefit programs than regional airlines. Should the attrition of our employees sharply increase, we may not be able to hire sufficient personnel to replace those leaving. In the event we are unable to hire and retain other qualified personnel, we may be unable to operate requested flight schedules under our capacity purchase agreements, which could result in a reduction in revenue and operating inefficiencies, such as incremental new-hire training costs, and our business and financial condition could be adversely affected.

Various negative economic or industry conditions may result in reductions to our flight schedules, which could materially and adversely affect our operations and financial condition.

Our operations and financial condition are affected by many changing economic and other conditions beyond our control, including, among others:

The effect of any, or some combination, of the foregoing economic and industry conditions on our operations or financial condition is virtually impossible to forecast; however, the occurrence of any or all of such conditions in a significant manner could materially and adversely affect our operations and financial condition and could cause our major airline partners to reduce the utilization levels of our aircraft under our code-share agreements.

Cybersecurity incidents, hardware or software failures or other information technology disruptions may negatively impact our operations, reputation and financial condition.

The performance and reliability of our technology are critical to our ability to compete effectively. Any internal technological error, failure or large-scale external interruption in the information systems, networks, hardware, software and technological infrastructure we depend on, such as U.S. air traffic control systems, power, telecommunications or the internet (collectively, “IT Systems”), may disrupt our internal network, impact our ability to conduct our business and result in lower revenue and/or increased costs. Our IT Systems (including those provided by third parties) and information about our employees and other individuals and proprietary information belonging to our business such as trade secrets (“Confidential Information”) are vulnerable to a variety of sources of interruption due to events beyond our control, including natural disasters, terrorist attacks, telecommunications or IT System failures, computer viruses, hackers and other security issues.

In addition, we face numerous and evolving cybersecurity risks that threaten the security, confidentiality, integrity and availability of our IT Systems and Confidential Information, including from diverse threat actors such as state-sponsored organizations, opportunistic hackers and hacktivists, as well as through diverse attack vectors, such as social engineering/phishing, security breaches, malfeasance by insiders, human or technological error, computer viruses, malicious or destructive code, misconfigurations, “bugs” or other vulnerabilities in commercial software that is integrated into our (or our service providers’) IT Systems, products or services, malware (including ransomware) and other attacks, including through fraud or other means of deception. The methods used to obtain unauthorized access, disable or degrade service or attack or sabotage systems are constantly evolving, and threat actors are becoming increasingly sophisticated in using techniques and tools – including artificial intelligence – that circumvent security controls, evade detection and remove forensic evidence. As a result we may be unable to anticipate or to detect, investigate, remediate or recover from attacks or incidents for long periods of time. Further, we may not be able to prevent all data breaches, misuses of data (including Confidential Information) or other cybersecurity incidents.

There can also be no assurance that our cybersecurity risk management program and processes, including our policies, controls or procedures, will be fully implemented, complied with or effective in protecting our IT Systems and Confidential Information. Because we rely on third-party vendors and service providers for functions critical to our business, including information technology infrastructure and services, successful cyberattacks that disrupt or result in unauthorized access to third-party IT Systems can materially impact our operations and financial results. Remote and hybrid working arrangements at our company (and at many third-party service providers) also increase cybersecurity risks due to the challenges associated with managing remote computing assets and security vulnerabilities that are present in many non-corporate and home networks.

We and certain of our third-party service providers have in the past experienced cybersecurity incidents. For example, as previously disclosed, our flight service was interrupted in 2021 due to a cyberattack that resulted in the installation of malware on our systems. The incident was considered fully remediated and settled through our insurer in 2023, and we are not aware of any ongoing liability. We cannot assure our cybersecurity risk management program will prevent such incidents from occurring in the future. While no incidents have had a material impact on our operations or financial results to date, we cannot guarantee that material incidents will not occur in the future as further described in “Item 1C. Cybersecurity”. Although we previously carried cybersecurity insurance coverage in the past, we currently do not have cybersecurity insurance coverage. Any cybersecurity incident or other adverse impact to the availability, integrity or confidentiality of our IT Systems or Confidential Information could compromise our ability to operate flights or technology systems, result in the loss of Confidential Information, legal claims or proceedings (such as class actions), regulatory investigations and enforcement actions, liability or regulatory penalties, disruption to our operations, damage to our reputation, loss of existing or future customers and/or significant incident response, system restoration or remediation and future compliance costs. Any or all of the foregoing could adversely affect our business, results of operations and financial condition.

Interruptions or disruptions in service at one of our hub airports, due to weather, system malfunctions or for any other reason, could have a material adverse impact on our operations.

We currently operate primarily through hubs supporting our major airline partners’ route networks across the United States. Nearly all of our flights either originate from or fly into one of these hubs. Our revenues depend primarily on our completion of flights and secondarily on service factors such as timeliness of departure and arrival. Any interruptions or disruptions could, therefore, severely and adversely affect us. Extreme weather such as hurricanes or tornados can cause flight disruptions, and, during periods of storms or adverse weather, our flights may be canceled or significantly delayed. We operate a significant number of flights to and from airports with potential winter related or other weather difficulties, including but not limited to, Chicago, Denver, Detroit, Minneapolis, Salt Lake City and San Francisco. A significant interruption or disruption in service at one of our hubs, due to adverse weather, system malfunctions, air traffic control disruptions, airport construction, security closures or otherwise, could result in the cancellation or delay of a significant portion of our flights and, as a result, could have a severe adverse impact on our operations and financial performance.

The occurrence of an aviation accident involving our aircraft would negatively impact our operations and financial condition.

An accident or incident involving one of our aircraft could result in significant potential claims of injured passengers and others, as well as repair or replacement of a damaged aircraft and its consequential temporary or permanent loss from service. In the event of an accident, our liability insurance may not be adequate to offset our exposure to potential claims and we may be forced to bear substantial losses from the accident. Substantial claims resulting from an accident in excess of our related insurance coverage would harm our operational and financial results. Moreover, any aircraft accident or incident, even if fully insured, could cause a public perception that our operations are less safe or reliable than other airlines and could affect our relationships with our major airline partners. In addition, any accident or incident involving a type of aircraft in our fleet could result in air travelers being reluctant to fly on our aircraft, and adversely impact our business, results of operations and financial condition.

We are subject to significant governmental regulation and potential regulatory changes.

All interstate air carriers, including SkyWest, are subject to regulation by the DOT, the FAA and other governmental agencies. Regulations promulgated by the DOT primarily relate to economic aspects of air service. The

FAA requires operating, air worthiness and other certificates; approval of personnel who may engage in flight, maintenance or operation activities; recordkeeping procedures in accordance with FAA requirements; and FAA approval of flight training and retraining programs. We cannot predict whether we will be able to comply with all present and future laws, rules, regulations and certification requirements or that the cost of continued compliance will not have a material adverse effect on our operations. We incur substantial costs in maintaining our current certifications and otherwise complying with the laws, rules and regulations to which we are subject. A decision by the FAA to ground, or require time-consuming inspections of or maintenance on, all or any of our aircraft for any reason may have a material adverse effect on our operations. In addition to state and federal regulation, airports and municipalities enact rules and regulations that affect our operations. From time to time, various airports throughout the country have considered limiting the use of smaller aircraft, such as our aircraft, at such airports. The imposition of any limits on the use of our aircraft at any airport at which we operate could have a material adverse effect on our operations.

We cannot predict the impact of potential regulatory changes that may affect our business or the airline industry as whole, including the potential impact of tariffs on aircraft deliveries. However, it is possible that these changes could adversely affect our business. Our business may be subject to additional costs or loss of government subsidies as a result of potential regulatory changes, which could have an adverse effect on our operations and financial results.

Changes to U.S. tariff and import/export regulations may have a negative effect on our suppliers and/or service providers and, in turn, could have a material adverse impact on our financial condition.

The United States has recently enacted and proposed to enact significant new tariffs. Additionally, President Trump has directed various federal agencies to further evaluate key aspects of U.S. trade policy and there has been ongoing discussion and commentary regarding potential significant changes to U.S. trade policies, treaties and tariffs. There continues to exist significant uncertainty about the future relationship between the United States and other countries with respect to such trade policies, treaties and tariffs. These developments, or the perception that any of them could occur, may have a material adverse effect on global economic conditions and the stability of global financial markets, and may significantly impact the cost of aircraft parts and supplies sourced internationally or impact the cost of service providers located outside of the United States, which in turn would negatively impact us.

Compliance, or failure to comply, with new or existing laws, regulations and other requirements relating to the privacy, security and handling of information about individuals could adversely affect our business, results of operations, or financial condition.

We receive information related to employees and other individuals in order to run our business. Laws, regulations and other requirements relating to the privacy, security and handling of information about individuals, alongside the application and interpretation of such requirements, are constantly evolving and developing and subject to change. There has been heightened legislative and regulatory focus on data privacy and security in the United States and elsewhere, including in relation to cybersecurity incidents, and it is possible that new laws, amendments to or interpretations of existing laws, regulations and other requirements may require us to incur significant costs, implement new processes or change our handling of information and business operations. In addition, any failure or perceived failure by us to comply with laws, regulations and other requirements relating to the privacy, security and handling of information could result in legal claims or proceedings (including class actions), regulatory investigations or enforcement actions. We could incur significant costs in investigating and defending such claims and, if found liable, pay significant damages or fines or be required to make changes to our business. Further, these proceedings and any subsequent adverse outcomes may subject us to significant negative publicity and an erosion of trust. If any of these events were to occur, our business, results of operations, and financial condition could be materially adversely affected.

Terrorist activities or warnings have dramatically impacted the airline industry and will likely continue to do so.

Past terrorist attacks and their aftermath have negatively impacted the airline industry in general, including our operations. If additional terrorist attacks are launched against the airline industry, there will be lasting consequences of such attacks, which may include loss of life, property damage, increased security and insurance costs, increased concerns about future terrorist attacks, increased government regulation and airport delays due to heightened security. Additionally, terrorist attacks and the fear of such attacks could negatively impact the airline industry, and result in decreased passenger traffic and yields, increased flight delays or cancellations associated with new government

mandates, as well as increased security, fuel and other costs. We cannot provide any assurance that these events will not harm the airline industry generally or our operations or financial condition in particular.

Risks Related to Our Code-Share Agreements with Our Major Airline Partners

Our business model is dependent on code-share agreements with four major airline partners.

Our business model depends on major airlines electing to contract with us instead of operating their own aircraft or regional jets. Some regional airlines are owned by a major airline. We have no guarantee that in the future our major airline partners will choose to enter into contracts with us instead of operating their own aircraft or regional jets or award more flying contracts to another regional airline. Our major airline partners are not prohibited from doing so under our code-share agreements. A decision by any of our major airline partners to phase out code-share relationships and instead acquire and operate their own regional jets or regional airline, or award more flying contracts to another regional airline, could have a material adverse effect on our financial results. Additionally, our major airline partners may be limited in the number of regional aircraft they can operate in their network due to aircraft scope limitations they have with their labor groups. Scope limitations could limit our ability to increase the number of aircraft operating under our code-share agreements.

As of December 31, 2024, 359 out of our total 492 aircraft in scheduled service were operating under a capacity purchase agreement or a prorate agreement with either United or Delta. If our code-share relationship with United or Delta were terminated, our operations would be significantly impacted and we would not likely have an immediate source of revenue or earnings to offset such loss. A termination of either of these relationships would likely have a material adverse effect on our financial condition, operating revenues and net income unless we are able to enter into satisfactory substitute arrangements for the utilization of the affected aircraft by other code-share partners, or, alternatively, obtain the airport facilities and gates and make the other arrangements necessary to fly as an independent airline. We may not be able to enter into substitute code-share agreements, and any such arrangements we might secure may not be as favorable to us as our current agreements. Operating an airline independent from major airline partners would be a significant departure from our business plan and would likely require significant time and resources and may not be a viable alternative.

Additionally, each of our agreements with our major airline partners is subject to certain early termination provisions, including uncured material performance breaches. We also currently use the systems, facilities and services of our major airline partners to support a significant portion of our operations, including airport and terminal facilities and operations, information technology support, ticketing and reservations, scheduling, dispatching, fuel purchasing and ground handling services. If our major airline partners cease to maintain any of these systems, close any of these facilities or no longer provide these services to us, due to termination of one of our code-share agreements, a strike or other labor interruption by personnel working for our major airline partners or for any other reason, we may not be able to obtain alternative systems, facilities or services on terms and conditions as favorable as those we currently receive, or at all. Since our revenues and operating profits are dependent on our level of flight operations, we could then be forced to significantly reduce our operations.

Reduced utilization levels of our aircraft under our capacity purchase agreements with our major airline partners would have a material adverse impact on the results of our operations and financial condition.

Under our capacity purchase agreements with our major airline partners, a portion of our compensation is based on pre-determined rates that are applied to our production, such as block hours, for the period. We also receive fixed monthly payments related to overhead costs and aircraft ownership costs from our major airline partners. Reduced utilization of our aircraft under our capacity purchase agreements will likely have a material adverse impact on the results of our operations and financial condition. During the year ended December 31, 2022, we amended our capacity purchase agreements with certain major airline partners that reduced certain future contractual fixed monthly payments and increased future contractual variable payments. A compensation structure that is weighted more to utilization and less to fixed payments could have a material adverse impact on the results of our operations and financial condition if utilization levels decrease. Additionally, amendments to our capacity purchase agreements that result in changes to our future scheduled fixed monthly payments will likely impact the timing of our revenue recognition. During the year ended December 31, 2024, the revenue we recognized was $44.9 million more than the fixed monthly cash payments received.

Although we currently anticipate we will recognize previously deferred revenue throughout 2025, future contract amendments or reduced utilization levels of our aircraft could negatively impact the timing of our revenue recognition.

Our major airline partners may experience events that negatively impact their financial strength or operations, which may also negatively impact our operations.

Our business model relies significantly on our major airline partners, and we may be negatively affected by their financial and operating strength. Events impacting airline travel, including pandemics or recessions, that negatively impact the financial strength of our major airline partners or have a long-term effect on the use of our major airline partners by airline travelers would likely have a material adverse effect on our business, financial condition and results of operations. If our major airline partners experience adverse effects to their operational or financial condition, they may be unable to make payments due to us under their capacity purchase agreements or may need to reduce utilization of our aircraft. Additionally, if one of our major airline partners undergoes bankruptcy, our agreement with such partner may not be assumed in bankruptcy and could be terminated. This and other events, which are outside of our control, could have a material adverse effect on our business, financial condition and results of operations.

Our growth may be limited with our major airline partners' flight systems.

Additional growth opportunities within our major airline partners’ flight systems are limited by various factors, including a limited number of regional aircraft each major airline partner can operate in its regional network due to scope limitations in its own labor agreements. Except as contemplated by our existing code-share agreements, we cannot be sure that our major airline partners will contract with us to fly any additional aircraft. We may not receive additional growth opportunities, or we may agree to modifications to our code-share agreements at less favorable terms in order to obtain additional aircraft, or for other reasons. Certain of our competitor regional airlines may agree to flying contract terms at lower rates or unfavorable contract terms, which could affect the terms offered to us. Even if we are offered growth opportunities by our major airline partners, those opportunities may involve economic terms or financing commitments that are unacceptable to us. Additionally, our major airline partners may reduce the number of regional jets in their system by not renewing or extending existing flying agreements with regional operators. Any one or more of these factors may reduce or eliminate our ability to expand our flight operations with our existing major airline partners.

There are long-term risks related to supply and demand of regional aircraft associated with our regional airline services strategy.

Various factors could change our major airline partners’ long-term strategy in using regional aircraft to support their network objectives. Such changes could result in a reduction in the number of regional aircraft our major airline partners operate in the future. If our major airline partners’ future strategies include a material reduction in regional aircraft generally or for specific aircraft types that we operate, the resulting decrease in demand in the aircraft we operate could have a material negative impact on our business and financial condition. Additionally, future developments of electric-powered aircraft designed to operate on routes typically served by regional aircraft could impact our major airline partners’ strategy and result in a reduction of demand or increase our capital expenditures and could have a material negative impact on our business and financial condition.

Due, in part, to the dynamic nature of the airline industry, major airlines may also make other strategic changes, such as changing or consolidating hub locations or operating mainline aircraft on routes previously served using regional aircraft. If our major airline partners were to make changes such as these in their strategy and operations, our operations and financial results could be adversely impacted.

Revenue levels from our prorate agreements with our major airline partners may not continue to increase and are terminable upon notice of 120 days or less. Additionally, revenue levels from our SWC operation may not continue to increase.

While our prorate agreements and SWC revenue increased $76.0 million, or 19.9%, for the year ended December 31, 2024, compared to the year ended December 31, 2023, there is no assurance our prorate revenue or SWC revenue will continue to increase in 2025 or thereafter. Future increases in prorate revenue is based on several factors subject to change including, but not limited to, passenger demand on prorate routes, approval of new routes with our major airline partners, maintenance required to return parked aircraft for service and labor availability. Additionally, there is no assurance we will continue to be awarded subsidy contracts under the Essential Air Service (EAS) program

on applicable prorate routes from the DOT going forward. Additionally, there is no assurance the EAS program will continue to receive funding by the U.S. Government. Future increases in SWC revenue is also based on several factors subject to change including, but not limited to, corporate or institutional demand for charter flights, competition for charter business and availability of other charter alternatives, such as ground transportation. Additionally, SWC applied for commuter authority from the DOT in 2022, which if approved, may allow SWC to expand its route strategy. There is no assurance that the DOT will approve SWC’s commuter authority application.

Our prorate flying agreements with our major airline partners permit each major airline partner to terminate the agreement in its discretion by giving us notice of 120 days or less. If one of our major airline partners elects to terminate a flying agreement with notice of 120 days or less, our ability to use the aircraft under an alternative agreement with similar economics may be limited, which could negatively impact our financial results. Additionally, even if we could subsequently place the aircraft into service with a different major airline partner, of which there can be no assurance, we likely would incur inefficiencies and incremental costs, such as changing the aircraft livery, during the transition period, which would negatively impact our financial results.

Disagreements regarding the interpretation of our code-share agreements with our major airline partners could have an adverse effect on our operating results and financial condition.

Long-term contractual agreements, such as our code-share agreements, are subject to interpretation and disputes may arise under such agreements if the parties to an agreement apply different interpretations to that agreement. Those disputes may divert management’s time and resources from the core operation of the business, and may result in litigation, arbitration or other forms of dispute resolution.

We have previously experienced disagreements with our major airline partners regarding the interpretation of various provisions of our code-share agreements. Some of those disagreements have resulted in litigation, and we may be subject to additional disputes and litigation in the future. Furthermore, there can be no assurance that any or all future disputes and related proceedings, if commenced, would be resolved in our favor. An unfavorable result in any such proceeding could have adverse financial consequences or require us to modify our operations. Such disagreements and their consequences could have an adverse effect on our operating results and financial condition.

We operate on-demand charter flights through our wholly-owned subsidiary, SWC, and such operations involve significant risk.

In 2022 we formed a new subsidiary, SWC, which had its first revenue generating charter flight in 2023. SWC offers on-demand charter service using CRJ200 aircraft in a 30 or less seat configuration under its own FAA operating certificate. As we grow operations, there may be significant risks, including that SWC may divert management’s attention or the Company’s resources from our core business and strategies and that the objectives of SWC may not materialize or may take longer to materialize than anticipated, including but not limited to SWC’s pending application with the DOT to operate under commuter authority.

The airline industry is highly competitive, which could adversely affect our operating results and financial condition.

The airline industry is highly competitive. We compete with other regional airlines on various factors including, but not limited to, labor resources, including pilots and mechanics; low operating costs; financial resources, including the ability to finance aircraft at competitive terms; geographical infrastructure; and overall customer service levels relating to on-time arrival and flight completion percentages. Our major airline partners rely on us to fly passengers from various locations into their hubs under our code-share agreements at competitive terms. We not only compete with other regional airlines, some of which are owned by or operated as code-share partners of major airlines, but we also indirectly face competition from low-cost carriers, such as Southwest, Allegiant, Spirit, JetBlue, Breeze and others, who compete with our major airline partners on many routes we operate. Certain of our competitors, including wholly-owned regional airline subsidiaries of our major airline partners, may have access to significantly greater financial and other resources than we do. Moreover, federal deregulation of the industry allows competitors to rapidly enter our markets and to quickly discount and restructure fares. The inability to remain competitive on the various factors valued by our major airline partners could adversely affect our operating results and financial condition.

Risks Related to Our Operating Costs and Personnel

Increases in labor costs, including pilot costs, flight attendant costs, maintenance costs and overhead costs may result in lower operating margins under our capacity purchase agreements.

Our business is labor intensive, requiring large numbers of pilots, flight attendants, mechanics and other personnel. Labor costs constitute a significant percentage of our total operating costs. Increases in our labor costs could result in a material reduction in our earnings. For example, during the years ended December 31, 2024 and 2023, our salary, wage and benefit costs constituted approximately 48.3% and 46.7% of our total operating costs, respectively. Various factors may result in higher attrition rates that could cause us to significantly increase compensation to our labor groups, such as higher compensation offered by other airlines and companies in the airline industry and/or general labor costs increases in the United States. Our inability to offset increased labor costs through rate increases under our capacity purchase agreements with all our major airline partners could negatively impact our operating costs. Currently, we believe our labor costs are competitive relative to other regional airlines. However, we cannot provide assurance that our labor costs going forward will remain competitive because of changes in supply and demand for labor in the regional airline industry. We compete against other airlines and businesses for labor in many highly skilled positions. If we are unable to hire, train and retain qualified employees at a reasonable cost, sustain employee engagement in our strategic vision, or if we are unsuccessful at implementing succession plans for our key staff, we may be unable to grow or sustain our business. Labor costs to recruit, incentivize and retain skilled employees may significantly increase in the future due to increased competition for the limited number of qualified industry personnel. Attrition rates that exceed our ability to hire and replace applicable workgroups could negatively impact our ability to generate revenue, negatively impact our operating results, increase our training and labor costs and our business prospects could be harmed.

Additionally, under our capacity purchase agreements with United, Delta, American and Alaska, a portion of our compensation is based upon pre-determined rates typically applied to production statistics (such as departures, block hours, flight hours and number of aircraft in service each month). The primary operating costs intended to be compensated by the pre-determined rates include our labor and training costs, certain aircraft maintenance expenses and overhead costs. During the year ended December 31, 2024, approximately 92.2% of our code-share operating costs were reimbursable at pre-determined rates and 7.8% of our code-share operating costs were directly reimbursed costs, often referred to as pass-through costs. Additionally, our aircraft maintenance costs may increase annually as our fleet ages at a higher rate than our pre-determined rates in our capacity purchase agreements. Also, on an individual aircraft basis, various in-depth maintenance procedures are typically scheduled to occur at multi-year intervals, which can result in maintenance expense fluctuations year-to-year. If our operating costs for labor, aircraft maintenance and overhead costs exceed the compensation earned from our pre-determined rates under our capacity purchase agreements, our financial position and operating results will be negatively affected.

Increased labor costs, pilot and other labor availability, labor disputes and unionization of our workforces may adversely affect our ability to conduct our business and reduce our profitability.

Any new labor agreement entered into by other regional carriers with their work forces may result in higher industry wages and increase pressure on us to increase the wages and benefits of our employees. If our labor agreements become uncompetitive, we may experience higher employee attrition and low employee job satisfaction, which may negatively impact our operating and financial results.

Our employees are represented by in-house associations; however, organizing efforts to join national unions among those employees occur from time to time. Such efforts will likely continue in the future and may ultimately result in some or all of our employees being represented by one or more national unions. If our employees were to unionize or be deemed to be represented by one or more national unions, negotiations with these unions could divert management’s attention and disrupt operations. Additionally, representation by a national union may limit our ability to have open communications with our employees, negatively impact our company culture and deter our ability to amend our compensation packages for market conditions in a timely manner. Moreover, we cannot predict the outcome of any future negotiations relating to union representation or collective bargaining agreements. A national union soliciting to represent our employees may represent employees at mainline carriers or other regional airlines and may have conflicting interests with those of our employees or SkyWest. Future collective bargaining agreements involving a national union and our employees may negatively impact our relationship with our employees and have an adverse impact on our operating and financial results.

We may experience an increase in fuel prices in our prorate and SWC operations.

Dependence on foreign imports of crude oil, limited refining capacity and the possibility of changes in government policy on jet fuel production, transportation and marketing make it difficult to predict the future availability of jet fuel. If there are additional outbreaks of hostilities or other conflicts in oil-producing areas or elsewhere, or a reduction in refining capacity (due to weather events, for example), or governmental limits on the production or sale of jet fuel, there could be a reduction in the supply of jet fuel and significant increases in the cost of jet fuel. Additionally, our operations may experience disruptions from temporary fuel shortages by our fuel vendors resulting from fuel quality issues, refueling disruption or other challenges. Major reductions in the availability of jet fuel or significant increases in its cost, or a continuation of high fuel prices for a significant period of time, would have a material adverse impact on us.

Pursuant to our capacity purchase agreements, our major airline partners have agreed to bear the economic risk of fuel price fluctuations on our contracted flights. However, we bear the economic risk of fuel price fluctuations on our prorate and SWC operations. As of December 31, 2024, we operated 25 CRJ200s under a prorate agreement with United and one CRJ900 and 16 CRJ700s or CRJ550s under a prorate agreement with Delta. As of December 31, 2024, we had 18 CRJ200s available for on-demand charter service through SWC. Our operating and financial results with respect to these prorate agreements and charter services can be negatively affected by the price of jet fuel in the event we are unable to increase our passenger fares. Additionally, in the event of prolonged low fuel prices, our competitors may lower their passenger ticket prices on routes that compete with our prorate or charter markets, which could negatively impact our prorate and charter revenue.

Our business could be harmed if we lose the services of our key personnel.

Our business depends upon the efforts of our chief executive officer, Russell A. Childs, and our other key management and operating personnel. We may have difficulty replacing management or other key personnel who cease to be employed by us and, therefore, the loss of the services of any of these individuals could harm our business. We do not maintain key-person insurance on any of our executive officers.

We may experience credit losses in excess of our estimated credit loss reserves.

Our financial results include estimated credit loss reserves associated with our accounts receivables, notes receivables and third-party debt guarantees. Our actual credit losses may exceed our estimated allowances, for a number of factors including but not limited to, counterparties’ bankruptcy, undervalued collateral and/or inability to liquidate collateral, which could negatively impact our financial condition and financial results.

We have guaranteed the indebtedness of third parties that may default on their debt and require us to pay.

In 2022, we agreed to guarantee debt for a 14 CFR Part 135 air carrier. The debt is secured by the Part 135 air carrier’s aircraft and engines and has a five-year term. At December 31, 2024, the outstanding debt for the guarantee was $14.1 million. In 2023, we agreed to guarantee debt for an aviation school. The debt is secured by the school’s aircraft and engines and has a five-year term. At December 31, 2024, the outstanding debt for the guarantee was $10.6 million. The purpose of these arrangements is to increase the potential number of commercial pilots in the Company’s hiring pipeline. In the event of default, if we are unable to sell the collateral, or the fair value is less than the required payment, it could negatively impact our financial condition and financial results. Additionally, there is no guarantee that the relationship with the entities will have a favorable effect on our ability to recruit pilots.

Risks Related to Operating and Leasing Regional Jet Aircraft and Engines

We are reliant on two aircraft manufacturers and one engine manufacturer.

We operate aircraft manufactured by Bombardier and Embraer. The issuance of FAA or manufacturer directives restricting or prohibiting the use of any Bombardier or Embraer aircraft types we operate could negatively impact our business and financial results. We are also dependent upon General Electric as the sole manufacturer of engines used on the aircraft we operate. Our operations could be materially and adversely affected by the failure or inability of Bombardier, Embraer, General Electric or other certified replacement part companies to provide sufficient parts or related maintenance and support services to us on a timely manner. Additionally, timing and availability of new aircraft deliveries could be delayed beyond our control.

We have a significant amount of contractual long-term debt obligations.

As of December 31, 2024, we had a total of approximately $2.7 billion in total long-term debt obligations. Our long-term debt obligations included $2.5 billion of debt used to finance aircraft and spare engines and $200.6 million related to borrowings under the Payroll Support Program Agreements with U.S. Department of the Treasury (“Treasury”). Our high level of fixed obligations could impact our ability to obtain additional financing to support additional expansion plans or divert cash flows from operations and expansion plans to service the fixed obligations.

Under our capacity purchase agreements, our major airline partners compensate us for our costs of owning the aircraft on a monthly basis. The aircraft compensation structure varies by agreement but is intended to cover either our aircraft principal and interest debt service costs or our aircraft depreciation and interest expense while the aircraft is under contract. In the event any of our major airline partners defaults under a capacity purchase agreement or we are unable to extend the flying contract terms on aircraft with ongoing financial obligations, our financial position and financial results could be materially adversely affected.

In addition, we may seek material amounts of additional financial liquidity in the short-term, which may include drawing down on SkyWest Airlines’ line of credit, the issuance of secured debt securities and/or the entry into other debt facilities, among other financial instruments. There can be no assurance as to the timing of any such drawdown or issuance, which may be in the near term, or that any such additional financing will be completed on favorable terms, or at all.

If our liquidity is materially diminished, we might not be able to timely pay our leases and debts or comply with certain covenants under SkyWest Airlines’ line of credit or with other material provisions of our contractual obligations.

We expect to issue debt to finance our anticipated aircraft purchases.

As of December 31, 2024, we have firm purchase commitments for 16 E175 aircraft and spare engines totaling $481.5 million. Over the next several years, if we continue to add new aircraft to our fleet, we anticipate using significant amounts of capital to acquire these aircraft.

There can be no assurance that our operations will generate sufficient cash flow or liquidity to enable us to obtain the necessary aircraft acquisition financing to replace our current fleet, or to make required debt service payments related to our existing or anticipated future obligations. Even if we meet all required debt, lease and purchase obligations, the size of these long-term obligations could negatively affect our financial condition and results of operations in many ways, including:

If we need additional capital and cannot obtain such capital on acceptable terms, or at all, we may be unable to realize our fleet replacement plans or take advantage of unanticipated opportunities.

The residual value of our owned aircraft may be less than estimated in our depreciation policies.

As of December 31, 2024, we had approximately $5.6 billion of property and equipment and related assets, net of accumulated depreciation. In accounting for these long-lived assets, we make estimates about the expected useful lives of the assets, the expected residual values of certain of these assets, and the potential for impairment based on the fair value of the assets and the cash flows they generate. Factors indicating potential impairment include, but are not limited to, amendments to our capacity purchase agreements that impact the anticipated cash flows for our aircraft, significant decreases in the market value of the long-lived assets, a significant change in the condition of the long-lived assets and operating cash flow losses associated with the use of the long-lived assets. In the event the estimated fair value of any of our aircraft types is determined to be lower than the net book value of the applicable aircraft type, such aircraft type in our fleet may be impaired and may result in a material impairment charge. An impairment on any of our aircraft types we

operate or an increased level of depreciation expense resulting from a change to our depreciation policy and assumptions could result in a material negative impact to our financial results. Future decisions to sell specific aircraft could potentially result in write-downs for aircraft held-for sale.

We lease aircraft and engines to third parties and the lessee may default under the lease terms, which could negatively affect our financial condition, cash flow and results of operations.

We leased five CRJ900 aircraft, 35 CRJ700 aircraft, and several CRJ aircraft engines to third parties as of December 31, 2024. In the event a lessee defaults under the terms of the lease agreement, we may incur additional costs, including legal and other expenses necessary to repossess the aircraft or engines, particularly if the lessee is contesting the proceedings or is in bankruptcy. We could also incur substantial maintenance, refurbishment or repair costs if a defaulting lessee fails to pay such costs and where such maintenance, refurbishment or repairs are necessary to put the aircraft or engines in suitable condition for remarketing or sale. We may also incur storage costs associated with any aircraft or engine that we repossess and are unable to place immediately with another lessee. Even if we are able to immediately place a repossessed aircraft or engine into service ourselves, or place the aircraft and engines under another lessee, we may not be able to do so at a similar or favorable lease rate. A lessee default under one of our lease agreements could negatively affect our financial condition, cash flow and results of operations.

We have entered into a strategic engine leasing joint venture that operates under joint control with a third party that involves significant risk.

We have entered into a strategic engine joint venture with a third party to lease engines to other parties. This strategic venture involves significant risks, including:

Although we currently participate in the management of our engine joint venture, our joint venture agreement requires unanimous approval over all significant actions. In addition, if we were unable to resolve a dispute with our joint venture partner that retains material managerial veto rights, we might reach an impasse that could require us to dissolve the joint venture at a time and in a manner that could negatively affect our financial results.

We entered into a partnership with a third party to develop demand for electric-powered aircraft that involves significant uncertainty and risk.

We have entered into a strategic partnership with Eve Holding, Inc. (“Eve”, formerly EVE UAM, LLC, an Embraer company), to develop a network of deployment for Eve’s eVTOL aircraft. To support this effort, SkyWest may provide assistance to Eve on vehicle design, vertiport specifications and the certification roadmap for eVTOL operations. This strategic partnership involves significant risks, including:

The effect of any, or some combination, of the foregoing risks could affect our partnership with Eve and future benefits may not materialize.

As of December 31, 2024, we held a warrant giving us the right to acquire 1,500,000 shares of common stock of Eve at an exercise price of $0.01 per share. At December 31, 2024, the fair value of the warrant was $8.2 million and future reductions in the trading market price of Eve’s common stock will likely negatively impact our net income.

We have invested in Contour, which involves significant risk and may not produce a satisfactory return on our investment.

As of December 31, 2024, we have invested $25.0 million in Contour, a 14 CFR Part 135 air carrier. This strategic investment involves significant risks, including:

​

The effect of any, or some combination, of the foregoing risks could negatively affect our financial results.

We are subject to various environmental requirements, including laws and regulations related to climate change and emissions. Compliance with new or existing environmental requirements could materially and adversely affect the Company's business plans, strategies and results of operations.

We are subject to federal, state and local laws and regulations relating to the protection of the environment, including those relating to aircraft and ground-based emissions, discharges into water systems, safe drinking water and the management of hazardous substances and waste materials. Certain legislative bodies and regulatory authorities are increasingly focused on climate change and have taken actions to implement additional laws, regulations and programs intended to protect the environment and may require specific reporting requirements. For example, the federal government, as well as several state and local governments, have implemented legislative and regulatory proposals and voluntary measures intended to reduce greenhouse gas emissions. Compliance with laws, regulations and other programs intended to reduce emissions or otherwise protect the environment may require us to reduce our emissions, secure carbon offset credits or otherwise pay for emissions, or make capital investments to modify certain aspects of our operations to reduce emissions. Future policy, legal and regulatory developments relating to the protection of the environment could increase our costs and have a material adverse effect on our operations.

We support our major airline partners’ goals and strategies to reduce carbon emissions on flights we operate under our code-share agreements and, as we work to support each of our major airline partners’ goals and strategies, initiatives to reduce emissions may not materialize and could materially and adversely affect the Company's business plans, strategies and results of operations.

During 2024, we produced approximately 5.6 million metric tons of CO₂e primarily from jet fuel emissions, using industry emissions factors for jet fuel gallons consumed on flights we operated under our code-share agreements. Under our flying contracts, our major airline partners are responsible for fuel procurement and selection of the type of aircraft we operate and have significant control over our flight schedules. Accordingly, we anticipate our major airline partners will take responsibility for carbon emissions incurred on our contract flights. Each of our major airline partners may have different goals, strategies and timelines to reduce carbon emissions on our flights. We are largely dependent on the direction from our major airline partners regarding long-term fuel saving initiatives such as engine innovations reducing fuel consumption, use of sustainable alternative fuels, carbon sequestration programs, air traffic flow routing efficiencies, among other initiatives. Each of our major airline partners may pursue alternative strategies and goals to reduce carbon emissions on flights we operate under our code-share agreements that may impact the rate at which we are able to reduce our carbon emissions, if at all. There is no assurance our major airline partners will take responsibility for carbon emissions incurred under our contract flights and no assurance future long-term fuel saving initiatives will materialize. In the event we pursue initiatives to reduce our carbon emissions, the cost could materially and adversely affect our business plans and results of operations.

Risks Related to Dividends, Share Repurchases and Our Common Stock

We cannot assure that we will resume dividend payments in the future and we cannot assure that we will continue stock repurchases in the future.

Historically, we have paid dividends and repurchased shares of our common stock in varying amounts. From April 2020 through September 30, 2022, we were restricted from paying dividends and repurchasing shares of our common stock under three Payroll Support Program Agreements and under a loan agreement with Treasury. During 2023, we resumed repurchasing shares of our common stock. We have not paid a dividend since 2020.

 There can be no assurance that we will resume our past practice of paying dividends on our common stock or that we will have the financial resources to pay such dividends. The future payment of dividends will depend upon our financial condition, alternative uses of the Company’s cash and results of operations and other factors deemed relevant by our board of directors.

In May 2023, our board of directors approved a share repurchase program, pursuant to which we are authorized to repurchase up to $250 million of our common stock. Under our May 2023 repurchase program we are authorized to repurchase such shares of common stock at prevailing market prices in the open market, in privately negotiated transactions or by other means in accordance with federal securities laws. Depending on market conditions and other factors, such repurchases may commence or be suspended from time to time by management without prior notice. The actual timing, number and value of shares repurchased will be determined by our management in its discretion. The number of shares of common stock that we may repurchase, including pursuant to the share repurchase program, will depend upon our financial condition and results of operations and other factors deemed relevant by our board of directors. There also can be no assurance that we will continue repurchasing shares of common stock under our May 2023 authorization, that our board of directors will approve additional share repurchase programs in the future or that we will have the financial resources to repurchase shares of common stock in the future.

Repurchases of our common stock pursuant to our share repurchase program and any future dividends could affect our stock price and increase its volatility. Additionally, our share repurchase program and any future dividends may reduce our cash reserves, which may impact our ability to finance future growth and to pursue possible future strategic opportunities and acquisitions.

Our common stock price may fluctuate significantly.

Volatility in our common stock price may prevent holders from selling shares at or above the prices paid for them. During the year ended December 31, 2024, our common stock closing price varied between a high of $115.11 and a low of $48.82. The market price of our common stock may fluctuate significantly for a variety of reasons, including: general market, political and other economic conditions; labor availability, including regional airline pilots; new regulatory pronouncements or changes in regulatory guidelines; announcements concerning the airline industry, our major airline partners or competitors; the market’s reaction to our quarterly or annual earnings or those of other companies in the airline industry; failure to meet financial analysts’ performance expectations or changes in recommendations by financial analysts for our common stock or the stock of other airlines; significant sales of our common stock, and other risks described in these “Risk Factors.” In recent periods, the stock market has experienced extreme declines and volatility, significantly impacting the market price of securities issued by many companies, including us and other companies in our industry.

Provisions of our articles of incorporation, by-laws and code-share agreements may limit the ability or desire of others to gain control of our Company.

Our ability to issue shares of preferred and common stock without shareholder approval may have the effect of delaying or preventing a change in control and may adversely affect the voting and other rights of the holders of our common stock, even in circumstances where such a change in control would be viewed as desirable by most investors. The provisions of the Utah Control Shares Acquisitions Act may also discourage the acquisition of a significant interest in or control of our Company. Additionally, our code-share agreements contain termination and extension trigger provisions related to change in control type transactions that may have the effect of deterring a change in control of our Company.

General Risk Factors

We may be a party to litigation in the normal course of business or otherwise, which could affect our financial condition and results of operations.

We may become party to or otherwise involved in legal proceedings, claims and government inspections or investigations and other legal matters, arising in the ordinary course of our business or otherwise, including, but not limited to those related to injury or tort, environmental, employment and commercial legal issues. Legal proceedings can be complex and take many months, or even years, to reach resolution, with the final outcome depending on a number of variables, some of which are not within our control. Litigation is subject to significant uncertainty and may be expensive, time-consuming and disruptive to our operations. Although we will vigorously defend ourselves in such legal proceedings, their ultimate resolution and potential financial and other impacts on us are uncertain. If a legal proceeding is resolved against us, it could result in significant compensatory damages or injunctive relief that could materially adversely affect our financial condition, results of operations and cash flows.

The adoption of new tax legislation or changes to existing tax laws and regulations could adversely affect our financial condition or results of operations.

We are subject to tax laws and regulations of the U.S. federal, state and local governments as well as various non-U.S. jurisdictions. Potential changes in existing tax laws, including future regulatory guidance, may impact our effective tax rate and tax payments. There can be no assurance that changes in tax laws or regulations, both within the United States and the other jurisdictions in which we operate, will not materially and adversely affect our effective tax rate, tax payments, financial condition and results of operations. Similarly, changes in tax laws and regulations that impact our major airline partners, customers or the economy generally may also impact our financial condition and results of operations.

In addition, tax laws and regulations are complex and subject to varying interpretations, and any significant failure to comply with applicable tax laws and regulations in all relevant jurisdictions could give rise to substantial penalties and liabilities. Any changes in enacted tax laws, rules or regulatory or judicial interpretations; any adverse outcome in connection with tax audits in any jurisdiction; or any change in the pronouncements relating to accounting for income taxes could materially and adversely impact our effective tax rate, tax payments, financial condition and results of operations.

We lease many of the buildings and associated land that we occupy. Most of these leases are for facilities at airports with various government agencies that control the use of the airport. We lease maintenance, training and office facilities in Salt Lake City, Utah, and we lease additional maintenance facilities in Boise, Idaho; Fresno, California; Tucson, Arizona; Chicago, Illinois; Detroit, Michigan; Nashville, Tennessee; South Bend, Indiana; and Fort Wayne, Indiana. We also lease ticket counters, passenger hold rooms, operating areas and other terminal space in many of the airports that we serve.

We own our corporate headquarters facilities located in St. George, Utah and a maintenance accessory shop facility in Salt Lake City, Utah. We also own maintenance facilities on land leases with airport authorities in Milwaukee, Wisconsin; Oklahoma City, Oklahoma; and Colorado Springs, Colorado.

ITEM 3. LEGAL PROCEEDINGS

We are subject to certain legal actions which we consider routine to our business activities. As of December 31, 2024, our management believed, after consultation with legal counsel, that the ultimate outcome of such legal matters was not likely to have a material adverse effect on our financial position, liquidity or results of operations. However, the ultimate resolution of these matters is inherently uncertain.

Risk Factors” for discussion of some of the uncertainties, risks and assumptions associated with these statements.

This section of this Annual Report on Form 10-K generally discusses 2024 and 2023 items and year-to-year comparisons between 2024 and 2023. Discussions of 2022 items and year-to-year comparisons between 2023 and 2022 that are not included in this Annual Report on Form 10-K can be found in the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

Overview

We have the largest regional airline operation in the United States. As of December 31, 2024, we offered scheduled passenger and air freight service with approximately 2,190 total daily departures to destinations in the United States, Canada and Mexico. Our fleet of E175, CRJ900, CRJ700 and CRJ550 have a multiple-class seat configuration, whereas our CRJ200 have a single-class seat configuration. During 2022, we formed SWC, which offers on-demand charter services using CRJ200 aircraft in a 30-seat configuration. As of December 31, 2024, we had 624 total aircraft in our fleet, including 492 aircraft in scheduled service or under contract pursuant to our code-share agreements, summarized as follows:

Our business model is based on providing scheduled regional airline service under code-share agreements (commercial agreements between airlines that, among other things, allow one airline to use another airline’s flight designator codes on its flights) with our major airline partners. Our success is principally centered on our ability to meet the needs of our major airline partners by providing a reliable and safe operation at attractive economics. During the year

ended December 31, 2024, we made changes to our fleet, including the addition of five new E175 aircraft and 20 partner-financed E175 aircraft.

We anticipate our fleet will continue to evolve, as we are scheduled to add a total of 15 new E175 aircraft with United from 2025 to 2026 and one new E175 aircraft with Alaska in 2025. We also have multiple agreements with United to place 30 used CRJ550 aircraft into service throughout 2025 and 2026. Timing of placing these additional aircraft into service, including delivery timing on acquired aircraft, may be subject to change as we are coordinating with our major airline partners in response to labor availability or other factors. Our primary objective in the fleet changes is to improve our profitability by adding new E175 aircraft and used CRJ700, CRJ550, CRJ900 and E175 aircraft, commonly referred to as “dual-class CRJ aircraft,” to capacity purchase agreements or prorate agreements, and potentially removing older aircraft from service that typically require higher maintenance costs.

For the year ended December 31, 2024, approximately 43.9% of our aircraft in scheduled service or under contract were operated for United, approximately 29.1% were operated for Delta, approximately 18.5% were operated for American and approximately 8.5% were operated for Alaska.

Historically, multiple contractual relationships with major airlines have enabled us to reduce our reliance on any single major airline code and to enhance and stabilize operating results through a mix of our capacity purchase agreements and our prorate flying agreements. For the year ended December 31, 2024, our capacity purchase revenue represented approximately 86.6% of our total flying agreements revenue and our prorate and SWC revenue, combined, represented approximately 13.4% of our total flying agreements revenue. On capacity purchase routes, the major airline partner controls scheduling, ticketing, pricing and seat inventories and we are compensated by the major airline partner at contracted rates based on completed block hours (measured from takeoff to landing, including taxi time), flight departures, the number of aircraft under contract and other operating measures. We control scheduling, pricing and seat inventories on certain prorate routes, and we share passenger fares with our major airline partners according to prorate formulas. We are also responsible for the operating costs of the prorate flights, including fuel and airport costs.

Financial Highlights

We had total operating revenues of $3.5 billion for the year ended December 31, 2024, a 20.2% increase compared to total operating revenues of $2.9 billion for the year ended December 31, 2023. We had net income of $323.0 million, or $7.77 per diluted share, for the year ended December 31, 2024, compared to net income of $34.3 million, or $0.77 per diluted share, for the year ended December 31, 2023. The significant items affecting our revenue and operating expenses during the year ended December 31, 2024, are outlined below:

Revenue

The number of aircraft we have in scheduled service or under contract pursuant to our code-share agreements and the number of block hours we incur on our flights are primary drivers of our flying agreements revenue under our capacity purchase agreements. The number of flights we operate and the corresponding number of passengers we carry are the primary drivers of our revenue under our prorate flying agreements. The number of aircraft we have in scheduled service or under contract pursuant to our code-share agreements increased from 485 as of December 31, 2023, to 492 as of December 31, 2024, or by 1.4%; and the number of block hours increased from 1.14 million in 2023 to 1.29 million in 2024, or by 13.3%, due to an increase in scheduled daily utilization of our aircraft driven by an increase in the number of available captains.

Our capacity purchase revenue increased $502.4 million, or 20.5%, from 2023 to 2024, primarily as a result of an increase in completed block hours for the comparable period and recognizing previously deferred revenue for the year ended December 31, 2024, compared to deferring the recognition of revenue on fixed monthly payments we received during the year ended December 31, 2023. As a result of a higher number of passengers carried on our prorate routes and an increase in the number of prorate and charter flights operated year-over-year, our prorate and SWC revenue increased $76.0 million, or 19.9%, in 2024, as compared to 2023.

Operating Expenses

Our total operating expenses increased $201.9 million, or 7.1%, for the year ended December 31, 2024, compared to the year ended December 31, 2023. The increase in operating expenses was primarily due to an increase in

our direct operating expenses associated with the increase in the number of flights we operated for the year ended December 31, 2024, compared to the year ended December 31, 2023. Departures increased from 691,962 for the year ended December 31, 2023 to 766,742 for the year ended December 31, 2024, or by 10.8%, and our total block hours increased 13.3% in 2024, as compared to 2023. Additional details regarding the increase in our operating expenses are described in the section of this Report entitled “Results of Operations.”

Fleet Activity

The following table summarizes our fleet scheduled for service or under contract as of 2024:

During 2024, we took delivery of five new E175 aircraft and placed the aircraft into service under capacity purchase agreements and we placed 20 partner-financed E175 aircraft into service under a capacity purchase agreement. We placed 23 SkyWest owned CRJ550 aircraft into service under a capacity purchase agreement or prorate agreement, while removing 22 CRJ700 aircraft from flying agreements. We also removed 14 CRJ200 aircraft from service during 2024. We are evaluating alternative uses for the CRJ200 aircraft removed from service.

2024 Compared to 2023

Operational Statistics

The following table sets forth our major operational statistics and the associated percentage changes for the periods identified below. The increase in block hours, departures and passengers carried during the year ended December 31, 2024, compared to the year ended December 31, 2023, was primarily due to an increase in the number of available captains during 2024, compared to 2023, which allowed for a higher scheduled utilization of our aircraft.

Operating Revenues

The following table summarizes our operating revenue for the periods indicated (dollar amounts in thousands):

Flying agreements revenue primarily consists of revenue earned on flights we operate under our capacity purchase agreements and prorate agreements with our major airline partners and on-demand charter flights. Lease, airport services and other revenues consist of revenue earned from leasing aircraft and spare engines to third parties separate from our capacity purchase agreements and providing airport counter, gate and ramp services.

We disaggregate our flying agreements revenue into the following categories (dollar amounts in thousands):

The increase in “Capacity purchase agreements flight operations revenue” of $438.9 million, or 22.2%, was primarily due to a 13.3% increase in block hour production and a decrease in deferred revenue related to fixed monthly payments for flight operations received under our capacity purchase agreements for the year ended December 31, 2024, compared to the year ended December 31, 2023. Under our capacity purchase agreements, we are paid a fixed amount per month per aircraft over the contract term. We recognize the total projected fixed monthly payments per aircraft as revenue proportionately to the number of block hours we complete for each reporting period, relative to the estimated number of block hours we anticipate completing over the remaining contract term. Under our capacity purchase agreements, the performance obligation of each completed flight is measured in block hours incurred for each completed flight. Beginning January 1, 2024, certain scheduled fixed monthly payments under our capacity purchase agreements transitioned to variable payments, which was the primary driver in recognizing previously deferred revenue during the year ended December 31, 2024, whereas we deferred recognizing revenue associated with the fixed monthly payments for the year ended December 31, 2023. Based on the number of completed block hours during the year ended December 31, 2024, we recognized $43.4 million of previously deferred revenue, net of unbilled revenue, related to the non-lease fixed monthly payments we received associated with our flight operations revenues. For the year ended December 31, 2023, we deferred recognizing $164.0 million of revenue, net of unbilled revenue, related to the non-lease fixed monthly payments received associated with our flight operations revenues. The timing of our revenue recognition related to the fixed payments associated with our flight operations will be adjusted over the remaining contract term for each capacity purchase agreement based on the number of block hours we complete each reporting period relative to the number of block hours we anticipate completing over the remaining contract term of each capacity purchase agreement.

The increase in “Capacity purchase agreements aircraft lease revenue” of $63.5 million, or 13.3%, was primarily due to a transition from certain scheduled fixed monthly lease payments to variable lease payments under our capacity purchase agreements beginning January 1, 2024. Under our capacity purchase agreements, a portion of the consideration we are paid is designed as reimbursement for certain aircraft ownership costs and is considered lease revenue, including fixed monthly payments and variable payments. We recognize the fixed monthly lease payments as lease revenue using the straight-line basis over the capacity purchase agreement term and variable lease payments are recognized in the period when the block hours are completed. We recognized $1.5 million of previously deferred lease revenue during the year ended December 31, 2024, using the straight-line basis for fixed monthly lease payments, whereas we deferred recognizing $78.5 million during the year ended December 31, 2023.

The deferred revenue balance applicable to each contract will be recorded as revenue over the term of each respective contract. For clarity, under our “Capacity purchase agreements flight operations revenue” and “Capacity purchase agreements aircraft lease revenue” combined, we recognized $44.9 million of previously deferred revenue, net of unbilled revenue, during the year ended December 31, 2024, compared to deferring revenue, net of unbilled revenue, of $242.5 million during the year ended December 31, 2023. Our total deferred revenue balance, associated with our “Capacity purchase agreements flight operations revenue” and our “Capacity purchase agreements aircraft lease revenue,” net of unbilled revenue, was $322.4 million as of December 31, 2024, compared to total deferred revenue, net of unbilled revenue of $367.3 million as of December 31, 2023.

The increase in prorate agreements and SWC revenue of $76.0 million, or 19.9%, was primarily due to an increase in prorate passengers and passenger revenue we received on routes we operated under our prorate agreements during the year ended December 31, 2024, compared to the year ended December 31, 2023. Additionally, a portion of

the increase was attributed to an increase in SWC revenue for the year ended December 31, 2024, compared to the year ended December 31, 2023, as SWC began operations in 2023.

The increase in lease, airport services and other revenues of $14.1 million, or 13.9%, was primarily due to an increase in the number of leased assets and lease rates for leases to third parties during 2024 compared to 2023.
