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

Current wording

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

Previous wording

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.

Current wording

We rely on third-party service providers to supply aircraft parts and for a variety of services and other functions critical to our business, particularly related to airframe and engine maintenance and repair. A service failure by one of our key service providers could result in a disruption to our operations. We use third party service providers in several areas including, but not limited to, aircraft maintenance, ground handling, fueling, telecommunication systems and information technology services. 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, we plan to continue 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.

Previous wording

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.

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.

Additionally, any integration of artificial intelligence into our operations, products or services, or those of our third party vendors, service providers or airline partners, is expected to pose new or unknown cybersecurity risks and challenges.

Previous wording

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.

Previous wording

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.

Previous wording

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.

Current wording

Previous wording

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.

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.

Previous wording

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.

Previous wording

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.

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.

Current wording

All interstate air carriers, including SkyWest, are subject to regulation by the DOT, the FAA and other governmental agencies.

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.

Current wording

The United States has recently enacted significant tariffs in excess of historical levels, and United States trade policies continue to evolve. Accordingly, 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. The recently enacted tariffs have had a significant impact on the cost of aircraft parts and supplies sourced internationally, including but not limited to, the non-U.S. manufactured components used on the E175 aircraft we import from Brazil. These added costs negatively impact us.

Previous wording

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.

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.

Current wording

During the year ended December 31, 2025, the revenue we recognized was $57.8 million more than the fixed monthly cash payments received. As of December 31, 2025, we have received a cumulative total of $264.6 million in fixed monthly cash payments that we have not recognized as revenue. Although we currently anticipate we will recognize previously deferred revenue for the year ending December 31, 2026, future contract amendments or reduced utilization levels of our aircraft could negatively impact the timing of our revenue recognition.

Previous wording

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

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 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. SWC was granted commuter authority from the DOT in 2025, allowing SWC to expand its route strategy. There is no assurance that SWC will be awarded EAS markets or other commuter routes in the future, nor that demand for its services will materialize as anticipated.

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.

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.

Previous wording

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.

Under our capacity purchase agreements with our major airline partners, 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, aircraft maintenance expenses and overhead costs. During the year ended December 31, 2025, approximately 93.0% of our code-share operating costs were reimbursable at pre-determined rates and 7.0% of our code-share operating costs were directly reimbursed costs, often referred to as pass-through costs. 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, 2025 and 2024, our salary, wage and benefit costs constituted approximately 45.3% and 48.3% of our total operating costs, respectively. Various factors may cause us to significantly increase compensation to our labor groups, such as higher compensation offered by other airlines or other factors impacting the labor market 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 profitability. 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.

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.

Previous wording

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.

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.

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.
