SKYWEST, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

​

(1) Condensed Consolidated Financial Statements

Basis of Presentation

The condensed consolidated financial statements of SkyWest, Inc. (“SkyWest” or the “Company”), its operating subsidiary SkyWest Airlines, Inc. (“SkyWest Airlines”), its leasing subsidiary SkyWest Leasing, Inc. (“SkyWest Leasing”) and its charter service subsidiary SkyWest Charter, LLC (“SWC”) included herein have been prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the following disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements reflect all adjustments that, in the opinion of management, are necessary to present fairly the results of operations for the interim periods presented. All adjustments are of a normal recurring nature, unless otherwise disclosed. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. The results of operations for the three months ended March 31, 2026, are not necessarily indicative of the results that may be expected for the year ending December 31, 2026.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates and assumptions.

Recent Accounting Pronouncements

In March 2024, the Financial Accounting Standards Board issued Accounting Standards Update No. 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Accounting Standards Codification (“ASC”) Subtopic 220-40) – Disaggregation of Income Statement Expenses”, which enhances the transparency and comparability of financial statements by requiring companies to disclose more granular information about expense components. The guidance is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the potential impact of adopting this new guidance on its consolidated financial statements and related disclosures.

(2) Operating Revenues

The Company recognizes revenue under its flying agreements and under its lease, airport services and other service agreements when the service is provided under the applicable agreement. Under the Company’s fixed-fee agreements (referred to as “capacity purchase” agreements) with United Airlines, Inc. (“United”), Delta Air Lines, Inc. (“Delta”), American Airlines, Inc. (“American”) and Alaska Airlines, Inc. (“Alaska”) (each, a “major airline partner”), the major airline partner generally pays the Company a fixed-fee for each departure, flight hour (measured from takeoff to landing, excluding taxi time) or block hour (measured from takeoff to landing, including taxi time) incurred, and an amount per aircraft in service each month, with additional incentives based on flight completion, on-time performance or other performance metrics. The major airline partner also directly pays for or reimburses the Company for certain direct expenses incurred under the capacity purchase agreement, such as fuel, airport landing fees and airport rents. Under the capacity purchase agreements, the Company’s performance obligation is met when each flight is completed, measured in completed block hours, and is reflected in flying agreements revenue. The transaction price for the capacity purchase agreements is determined from the fixed-fee consideration, incentive consideration and directly reimbursed expenses earned as flights are completed over the agreement term. For the three months ended March 31, 2026 and 2025, capacity

Table of Contents

purchase agreements represented approximately 82.8% and 85.7% of the Company’s flying agreements revenue, respectively.

Under the Company’s “prorate” agreements, the major airline partner and the Company negotiate a passenger fare proration formula, pursuant to which the Company receives a percentage of the ticket revenues for those passengers traveling for one portion of their trip on a Company aircraft and the other portion of their trip on the major airline partner. Under the Company’s prorate agreements, the performance obligation is met and revenue is recognized when each flight is completed based upon the portion of the prorate passenger fare the Company determines that it will receive for each completed flight. The transaction price for the prorate agreements is determined from the proration formula derived from each passenger ticket amount on each completed flight over the agreement term. Certain routes under the Company’s prorate agreements are subsidized by the U.S. Department of Transportation under the Essential Air Service (“EAS”) program, a program created to ensure small communities in the United States maintain a minimum level of scheduled air service. The EAS contracts are generally between two and three years in duration and the Company recognizes EAS revenue on a per-completed-flight basis pursuant to the terms of each contract. In the event the Company receives upfront consideration for an EAS contract, the Company recognizes the revenue on a per-completed flight basis over the EAS contract term. Under the Company’s charter operations, SWC, the Company negotiates a fare for the charter flight with the customer. The performance obligation is met and revenue is recognized upon completion of the flight. For the three months ended March 31, 2026 and 2025, prorate agreements and SWC revenue represented approximately 17.2% and 14.3% of the Company’s flying agreements revenue, respectively.

The following table disaggregates the Company’s flying agreements revenue by type for the three months ended March 31, 2026 and 2025 (in thousands):

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | For the three months ended March 31,
​ | ​ ​ ​ | 2026 | ​ ​ ​ | 2025
Capacity purchase agreements flight operations revenue (non-lease component) | ​ | $ | 633,869 | ​ | $ | 639,153
Capacity purchase agreements fixed aircraft lease revenue | ​ | ​ | 104,455 | ​ | ​ | 110,988
Capacity purchase agreements variable aircraft lease revenue | ​ |  | 71,373 | ​ |  | 35,039
Prorate agreements and SWC revenue | ​ |  | 168,188 | ​ |  | 130,814
Flying agreements revenue | ​ | $ | 977,885 | ​ | $ | 915,994

​

The Company allocates the total consideration received under its capacity purchase agreements between lease and non-lease components based on stand-alone selling prices. A portion of the Company’s compensation under its capacity purchase agreements relates to operating the aircraft, identified as the non-lease component of the capacity purchase agreement. The Company recognizes revenue attributed to the non-lease component received as fixed-fees for each departure, flight hour or block hour on an as-completed basis for each reporting period. The Company recognizes revenue attributed to the non-lease component received as fixed monthly payments per aircraft proportionate to the number of block hours completed during each reporting period, relative to the estimated number of block hours the Company anticipates completing over the remaining contract term. Accordingly, the Company’s revenue recognition will likely vary from the timing of cash receipts under the Company’s capacity purchase agreements. The Company refers to cash received under its capacity purchase agreements prior to recognizing revenue as “deferred revenue,” and the Company refers to revenue recognized prior to billing its major airline partners under its capacity purchase agreements as “unbilled revenue” for each reporting period.

A portion of the Company’s compensation under its capacity purchase agreements is designed to reimburse the Company for certain aircraft ownership costs. The consideration for aircraft ownership costs varies by agreement but is intended to compensate the Company for providing its aircraft under the contract. The consideration received for the use of the aircraft under the Company’s capacity purchase agreements is accounted for as lease revenue, inasmuch as the agreements identify the “right of use” of a specific type and number of aircraft over a stated period of time. The lease revenue associated with the Company’s capacity purchase agreements is accounted for as an operating lease and is reflected as flying agreements revenue on the Company’s consolidated statements of comprehensive income. The Company recognizes fixed monthly lease payments as lease revenue using the straight-line basis over the capacity purchase agreement term and variable lease payments in the period when the block hours are completed. The Company has not separately stated aircraft rental income and aircraft rental expense in the consolidated statement of

comprehensive income because the use of the aircraft is not a separate activity of the total service provided under the capacity purchase agreements.

The following table summarizes the amount of deferred revenue, recognition of previously deferred revenue and change in unbilled revenue for revenue recognized that is in excess of (or less than) the fixed monthly non-lease and lease payments received under the Company’s capacity purchase agreements for the three months ended March 31, 2026 and 2025 (in thousands):

The Company’s capacity purchase and prorate agreements include weekly provisional cash payments from the respective major airline partner based on a projected level of flying each month. The Company and each major airline partner subsequently reconcile these payments to the actual completed flight activity on a monthly or quarterly basis.

In several of the Company’s agreements, the Company is eligible to receive incentive compensation upon the achievement of certain performance criteria. The incentives are defined in the agreements and are measured and determined on a monthly or annual basis. At the end of each period during the term of an agreement, the Company calculates the incentives achieved during that period and recognizes revenue attributable to that agreement accordingly, subject to the variable constraint guidance under ASC Topic 606.

As of March 31, 2026, the Company had 500 aircraft in scheduled service or under contract pursuant to code-share agreements. The Company’s fleet includes Embraer E175 regional jet aircraft (“E175”), Canadair CRJ900 regional jet aircraft (“CRJ900”), Canadair CRJ700 regional jet aircraft (“CRJ700”), a 50-seat configuration of the CRJ700 aircraft, commonly referred to as a “CRJ550,” and Canadair CRJ200 regional jet aircraft (“CRJ200”).

* | The Company’s prorate agreements are based on specific routes, not a specific aircraft count. The number of aircraft listed above for each prorate agreement approximates the number of aircraft the Company uses to serve the prorate routes.

In addition to the contractual agreements described above, as of March 31, 2026, SkyWest Airlines reached agreements with certain major airline partners to place additional aircraft under capacity purchase agreements as summarized below. The Company is coordinating with its major airline partners regarding the timing of upcoming fleet deliveries and the delivery timing referenced below is subject to change.

| ● | Capacity purchase agreement with United for eight new E175 aircraft, which are scheduled for delivery in 2026. The Company anticipates financing the aircraft through debt.

Table of Contents

| ● | Capacity purchase agreement with Delta for 16 new E175 aircraft. 10 new E175 aircraft are currently scheduled for delivery in 2027 and six new E175 aircraft are scheduled for delivery in 2028. The Company anticipates financing the aircraft through debt.

| ● | Capacity purchase agreement with United for 18 used CRJ550 aircraft that are anticipated to be placed into service by 2027. Pursuant to this agreement, the Company is in the process of converting its owned CRJ700s to CRJ550s.

When an aircraft is scheduled for expiration from a capacity purchase agreement, the Company may, as practical under the circumstances, negotiate an extension with the respective major airline partner, negotiate the placement of the aircraft with another major airline partner, return the aircraft to the major airline partner when the aircraft is provided by the major airline partner, place owned aircraft for sale or pursue other uses for the aircraft. Other uses for the aircraft may include placing the aircraft in a prorate agreement, leasing the aircraft to a third party or disassembling aircraft components such as the engines and parts to be used as spare inventory.

Lease, airport services and other revenues primarily consist of revenue generated from aircraft and spare engines leased to third parties, maintenance services provided to third parties and airport customer service agreements, such as gate and ramp agent services at various airports where the Company has been contracted by third parties to provide such services. The following table represents the Company’s lease, airport services and other revenues for the three months ended March 31, 2026 and 2025 (in thousands):

​

Of the Company’s $5.9 billion of property and equipment, net of accumulated depreciation, as of March 31, 2026, $240.8 million of regional jet aircraft and spare engines were leased to third parties under operating leases. The Company’s mitigation strategy for the residual asset risks of these assets includes leasing aircraft and engine types that can be operated by the Company in the event of a default. Additionally, the operating leases typically have specified lease return condition requirements paid by the lessee to the Company and the Company typically maintains inspection rights under the leases.

The transaction price for airport customer service agreements is determined from an agreed-upon rate by location applied to the applicable number of flights handled by the Company over the agreement term.

The Company’s operating revenues could be impacted by several factors, including changes to the Company’s code-share agreements with its major airline partners, changes in flight schedules, contract modifications resulting from contract renegotiations, the Company’s ability to earn incentive payments contemplated under the Company’s code-share agreements and settlement of reimbursement disputes with the Company’s major airline partners.

Other ancillary revenues commonly associated with airlines, such as baggage fee revenue, ticket change fee revenue and the marketing component of the sale of mileage credits, are retained by the Company’s major airline partners on flights that the Company operates under its code-share agreements.

Allowance for Credit Losses

The Company has an allowance for credit losses associated with its accounts receivable, notes receivable and third-party debt guarantees. The Company monitors publicly available credit ratings for entities for which the Company has a significant receivable balance or guarantee. As of March 31, 2026, the Company had gross receivables of $176.6 million in current assets and gross receivables of $256.7 million in other long-term assets. As of December 31, 2025, the Company had gross receivables of $163.3 million in current assets and gross receivables of $266.3 million in other long-term assets. The Company has established credit loss reserves based on publicly available historic default rates issued by a third party for companies with similar credit ratings, factoring in the amount and term of the Company’s respective accounts receivable, notes receivable or guarantees. During the three months ended March 31, 2026, there were no significant changes in the outstanding accounts receivable, notes receivable, guarantees or credit ratings of the entities.

The following table summarizes the changes in allowance for credit losses (in thousands):

​ | ​ | ​ | ​

(3) Capital Transactions

Stock-Based Compensation

During the three months ended March 31, 2026, the Company granted 76,648 performance shares and 32,850 restricted stock units to certain employees of the Company under the SkyWest, Inc. Amended and Restated 2019 Long-Term Incentive Plan. The performance shares have a three-year vesting period during which the recipient must remain employed with the Company. The number of performance shares awardable from the 2026 grants can range from 0% to 200% of the original amount granted depending on the Company’s performance over three one-year measurement periods against the pre-established targets. The restricted stock units granted in 2026 will vest in three equal installments, with one-third vesting each year on the grant date anniversary. Upon vesting, each performance share and restricted stock unit will be replaced with one share of common stock. The weighted average fair value of these performance shares and restricted stock units on their date of grant was $101.47 per share.

The Company accounts for forfeitures of restricted stock units and performance shares when forfeitures occur. The estimated fair value of the performance shares and restricted stock units is amortized over the applicable vesting periods. Stock-based compensation expense for the performance shares is based on the Company’s anticipated outcome of achieving the performance metrics. During the three months ended March 31, 2026 and 2025, the Company recorded pre-tax stock-based compensation expense of $4.4 million and $4.7 million, respectively.

(4) Stock Repurchase

The Company’s Board of Directors (the “Board”) adopted a stock repurchase program in May 2023, which authorizes the Company to repurchase shares of the Company’s common stock in the public market or in private transactions, from time to time, at prevailing prices. Under the repurchase program, the Board initially authorized up to $250.0 million for the repurchase of the Company’s common stock. In May 2025, the Board approved a $250.0 million increase to the existing repurchase program. At March 31, 2026, $137.8 million remained available under the repurchase program.

During the three months ended March 31, 2026, the Company repurchased 782,900 shares of common stock for $75.3 million at a weighted average price per share of $96.18. The Company also recorded $0.1 million of excise tax

13

Table of Contents

related to the stock repurchases as treasury stock in the Company’s stockholders’ equity for the three months ended March 31, 2026. During the three months ended March 31, 2025, the Company repurchased 140,658 shares of common stock for $13.7 million at a weighted average price per share of $97.27. The Company did not record excise tax related to the stock repurchases for the three months ended March 31, 2025.

(5) Net Income Per Common Share

Basic net income per common share (“Basic EPS”) excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per common share (“Diluted EPS”) reflects the potential dilution that could occur if stock options or other contracts to issue common stock were exercised or converted into common stock. The computation of Diluted EPS does not assume exercise or conversion of securities that would have an anti-dilutive effect on net income per common share. During the three months ended March 31, 2026 and 2025, 155,000 and 268,000 performance shares (at target performance) were excluded from the computation of Diluted EPS because the Company had not achieved the minimum target thresholds for these shares as of March 31, 2026 and 2025, respectively.

The calculation of the weighted average number of common shares outstanding for Basic EPS and Diluted EPS are as follows for the periods indicated (in thousands, except per share data):

(6) Segment Reporting

GAAP requires disclosures related to components of a company for which separate financial information is available to, and regularly evaluated by, the Company’s chief operating decision maker when deciding how to allocate resources and in assessing performance.

The Company’s two reportable segments consist of (1) the operations of SkyWest Airlines and SWC (collectively, “SkyWest Airlines and SWC”) and (2) SkyWest Leasing activities.

The Company’s chief operating decision maker analyzes the profitability of aircraft separately from the profitability of the Company’s capital deployed for new aircraft and the related aircraft financings, including the Company’s E175 fleet. The SkyWest Airlines and SWC segment includes revenue earned under the applicable capacity purchase agreements attributed to operating such aircraft and the respective operating costs, and revenue and operating expenses attributed to prorate agreements and airport services agreements. The SkyWest Leasing segment includes applicable revenue earned under the applicable capacity purchase agreements attributed to the ownership of new aircraft acquired through the issuance of debt and the respective depreciation and interest expense of such aircraft. The SkyWest Leasing segment also includes the activity of leasing regional jet aircraft and spare engines to third parties and other activities. The SkyWest Leasing segment’s total assets and capital expenditures include new aircraft acquired through the issuance of debt and assets leased to third parties.

The chief operating decision maker assesses performance for each segment and decides how to allocate resources based on income before income taxes. The chief operating decision maker uses the segment profit or loss

In addition to the table above, in 2024, the Company entered into a master equipment purchase agreement with another airline to acquire certain airframes and engines and lease the assets back to the airline under a five-year term. The Company accounted for the transaction as a failed sale-leaseback in accordance with ASC 842 as the criteria for a sale were not met. At March 31, 2026, the Company estimated the remaining financing obligation under the agreement will be between $20.0 million and $25.0 million and anticipated closing on the remaining financings during 2026.

Guarantees

In 2022, the Company agreed to guarantee $19.8 million of 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. In exchange for providing the guarantee, the Company received 6.5% of the guaranteed amount as consideration, payable in the estimated value of common stock of the Part 135 air carrier, all of which was sold in 2023. The purpose of this guarantee is to help reduce the financing costs of aircraft for the third party in an effort to increase the potential number of commercial pilots in the Company’s hiring pipeline. The balance of the debt under the guarantee was $12.2 million as of March 31, 2026.

The Company recorded the estimated credit loss associated with the guarantees based on publicly available historical default rates issued by a third party for companies with similar credit ratings, factoring the collateral and guarantee term.

(8) Fair Value Measurements

The Company holds certain assets that are required to be measured at fair value in accordance with GAAP. The Company determined the fair value of these assets based on the following three levels of inputs:

​ | ​ | ​ | ​ | ​
Level 1 | ​ | — | ​ | Quoted prices in active markets for identical assets or liabilities.
Level 2 | ​ | — | ​ | Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Some of the Company’s marketable securities primarily utilize broker quotes in a non-active market for valuation of these securities.
Level 3 | ​ | — | ​ | Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities, therefore requiring an entity to develop its own assumptions.

(10) Investments in Other Companies

Equity Method Investments

During 2019, the Company created a joint venture with Regional One, Inc. (“Regional One”) and, as of March 31, 2026, has invested a total of $26.6 million for a 75% ownership interest in Aero Engines, LLC. (“Aero Engines”). The primary purpose of Aero Engines is to lease engines to third parties. Aero Engines requires unanimous approval from the Company and Regional One for all material transactions. Although the Company determined Aero Engines is a variable interest entity, Aero Engines has no primary beneficiary as no one party has power over Aero Engines. Accordingly, the Company accounts for its investment in Aero Engines under the equity method. The Company’s exposure in its investment in Aero Engines primarily consists of the Company’s portion of income or loss from Aero Engines’ engine lease agreements with third parties and the Company’s ownership percentage in Aero Engines’ engines book value. Aero Engines had no debt outstanding as of March 31, 2026. During 2025, the Company received a $12.0 million distribution from Aero Engines, which reduced the Company’s investment balance in Aero Engines. As of March 31, 2026 and December 31, 2025, the Company’s investment balance in Aero Engines was $13.4 million and $12.8 million, respectively, and was recorded in “Other Assets” on the Company’s consolidated balance sheet. The Company’s portion of income generated by Aero Engines for the three months ended March 31, 2026 and 2025, was $0.5 million and $0.6 million, respectively, which was recorded in “Other expense, net” on the Company’s consolidated statements of comprehensive income.

In December 2023, the Company invested $9.9 million for a 9.9% ownership interest in Corporate Flight Management, Inc. d/b/a Contour Airlines (“Contour”), a 14 CFR Part 135 air carrier. In January 2024, the Company invested an additional $15.1 million in Contour. The Company had a 25% ownership interest in Contour at March 31,

2026 and held one of five seats, or 20%, on Contour’s board of directors. The Contour arrangement also includes an asset provisioning agreement under which the Company will provide CRJ airframes, engines and rotable parts to Contour. The Company accounts for its investment in Contour under the equity method where the investment is reported at cost and adjusted each period for the Company’s share of Contour’s income or loss, recorded on a one quarter lag. For the three months ended March 31, 2026 and 2025, the Company recorded income of $0.7 million and $0.9 million, respectively, related to its Contour investment, its portion of income generated by Contour, which was recorded in “Other expense, net” on the Company’s consolidated statements of comprehensive income. As of March 31, 2026 and December 31, 2025, the Company’s investment balance in Contour was $23.5 million and $22.8 million, respectively, and was recorded in “Other Assets” on the Company’s consolidated balance sheet. At March 31, 2026, the Company had $7.9 million in notes receivable from Contour related to the sale of aircraft under the asset provisioning agreement. The notes are secured by aircraft and collectible within three years.

The Company assesses investments for impairment whenever events or changes in circumstances indicate that the carrying value of an investment may not be recoverable.

Fair Value Method Investment

In 2021, the Company entered into a strategic arrangement with Eve Holding, Inc. (“Eve”), to develop a network of deployment for Eve’s electric vertical takeoff and landing aircraft. As of March 31, 2026 and December 31, 2025, the Company held 1.1 million common shares of Eve. During the three months ended March 31, 2026, the Company recorded an unrealized loss of $1.6 million in “Other expense, net” on the Company’s consolidated statements of comprehensive income related to its investment in Eve. During the three months ended March 31, 2025, the Company recorded an unrealized loss of $3.2 million in “Other expense, net” on the Company’s consolidated statements of comprehensive income related to its investment in Eve. As of March 31, 2026 and December 31, 2025, the fair value of the Company’s investment in Eve was $2.6 million and $4.3 million, respectively, and was recorded in “Other Assets” on the Company’s consolidated balance sheet.

(11) Income Taxes

The Company’s effective tax rate for the three months ended March 31, 2026 was 5.6%. The Company’s effective tax rate for the three months ended March 31, 2026 varied from the federal statutory rate of 21.0% primarily due to the impact of a discrete tax benefit from additional tax deductions generated from employee equity awards that vested at a stock price above the grant date price during the three months ended March 31, 2026, offset by the provision for state income taxes and the impact of non-deductible expenses.

The Company’s effective tax rate for the three months ended March 31, 2025 was 16.7%. The Company’s effective tax rate for the three months ended March 31, 2025 varied from the federal statutory rate of 21.0% primarily due to the impact of a discrete tax benefit from additional tax deductions generated from employee equity awards that vested during the three months ended March 31, 2025, offset by the provision for state income taxes and the impact of non-deductible expenses.

(12) Legal Matters

The Company is subject to certain legal actions which it considers routine to its business activities. As of March 31, 2026, the Company’s 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 the Company’s financial position, liquidity or results of operations.

Overview

We have the largest regional airline operation in the United States through our operating subsidiary SkyWest Airlines, Inc. (“SkyWest Airlines”). As of March 31, 2026, we offered scheduled passenger and air freight service with approximately 2,370 total daily departures to destinations in the United States, Canada and Mexico. Our fleet of Embraer E175 regional jet aircraft (“E175”), Canadair CRJ900 regional jet aircraft (“CRJ900”) and Canadair CRJ700 regional jet aircraft (“CRJ700”), including a 50-seat configuration of the CRJ700 aircraft, commonly referred to as a “CRJ550,” have a multiple-class seat configuration, whereas our Canadair CRJ200 regional jet aircraft (“CRJ200”) have a single-class seat configuration. SWC offers on-demand charter services using CRJ200 aircraft in a 30-seat configuration. As of March 31, 2026, we had 639 total aircraft in our fleet, including 500 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. In exchange for such services, our major airline partners pay us either fixed fees to operate the flight, referred to as “capacity purchase agreement,” or we receive a percentage of applicable passenger ticket revenues on the designated flights we operate, referred to as “prorate agreement.” 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. From March 31, 2025, to March 31, 2026, we made changes to our fleet, including the addition of eight new E175 aircraft and one partner-financed E175 aircraft.

We anticipate our fleet will continue to evolve, as we are scheduled to add a total of eight new E175 aircraft with United in 2026 and 16 new E175 aircraft with Delta between 2027 and 2028 (which are expected to replace 15 CRJ900s and two CRJ700s we are currently flying under contract with Delta). We also have multiple agreements with United to place 18 used CRJ550 aircraft into service between 2026 and 2027. 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

22

Table of Contents

major airline partners in response to labor availability or other factors. As of March 31, 2026, we operated 19 CRJ900s owned by Delta, and we anticipate returning these 19 aircraft to Delta over the next two years. 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 aircraft” due to the first-class seat offerings, to our capacity purchase agreements or prorate agreements, and potentially removing older aircraft from service that typically require higher maintenance costs. Additionally, during the three months ended March 31, 2026, we announced a new configuration of the CRJ200 aircraft that will have 41 seats, including seven first-class seats (referred to as a “CRJ450” aircraft). We anticipate operating the first CRJ450 in scheduled service by the end of 2026. We anticipate completing the conversion of approximately 50 CRJ200s to the CRJ450 configuration by 2028.

As of March 31, 2026, approximately 45.2% of our aircraft in scheduled service or under contract were operated for United, approximately 27.8% were operated for Delta, approximately 18.4% were operated for American and approximately 8.6% 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 agreements. For the three months ended March 31, 2026, our capacity purchase revenue represented approximately 82.8% of our total flying agreements revenue and our prorate and SWC revenue, combined, represented approximately 17.2% 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.

First Quarter Summary

We had total operating revenues of $1.0 billion for the three months ended March 31, 2026, a 6.8% increase compared to total operating revenues of $948.5 million for the three months ended March 31, 2025. We had net income of $101.7 million, or $2.50 per diluted share, for the three months ended March 31, 2026, compared to net income of $100.6 million, or $2.42 per diluted share, for the three months ended March 31, 2025. The significant items affecting our revenue and operating expenses during the three months ended March 31, 2026, 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 agreements. The number of aircraft we have in scheduled service or under contract pursuant to our code-share agreements increased from 488 as of March 31, 2025 to 500 as of March 31, 2026, or by 2.5%; and the number of block hours increased from 352,155 for the three months ended March 31, 2025 to 362,933 for the three months ended March 31, 2026, or by 3.1%, primarily due to an increase in the number of aircraft operating under our capacity purchase agreements.

Our capacity purchase revenue increased $24.5 million, or 3.1%, for the three months ended March 31, 2026, as compared to the three months ended March 31, 2025, primarily as a result of an increase in completed block hours for the comparable periods. 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 $37.4 million, or 28.6%, for the three months ended March 31, 2026, as compared to the three months ended March 31, 2025.

Operating Expenses

Our total operating expenses increased $80.4 million, or 9.9%, for the three months ended March 31, 2026, compared to the three months ended March 31, 2025. 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 and higher

pilot training costs for the three months ended March 31, 2026, compared to the three months ended March 31, 2025. Departures increased from 201,838 for the three months ended March 31, 2025 to 204,019 for the three months ended March 31, 2026, or by 1.1%, and our total block hours increased 3.1% for the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. Additional details regarding the increase in our operating expenses are described in the section of this Report entitled “Results of Operations.”

Critical Accounting Policies and Estimates

Our significant accounting policies are summarized in Note 1 to our consolidated financial statements for the year ended December 31, 2025, and Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” which are presented in our Annual Report on Form 10-K for the year ended December 31, 2025. Critical accounting policies are those policies that are most important to the preparation of our consolidated financial statements and require management’s subjective and complex judgments due to the need to make estimates about the effect of matters that are inherently uncertain. Our critical accounting policies relate to revenue recognition, long-lived assets, and income tax. The application of these accounting policies involves the exercise of judgment and the use of assumptions as to future uncertainties and, as a result, actual results will likely differ, and may differ materially, from such estimates. There have been no significant changes in our critical accounting estimates during the three months ended March 31, 2026.

Results of Operations

Three Months Ended March 31, 2026 and 2025

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 and departures during the three months ended March 31, 2026, compared to the three months ended March 31, 2025, was primarily due to additional aircraft operating under our capacity purchase agreements and an increase in the number of block hours incurred per aircraft due to the higher scheduled utilization of our aircraft during the three months ended March 31, 2026, compared to the three months ended March 31, 2025.

​ | ​ ​ ​ | 2026 | ​ ​ ​ | 2025 | ​ ​ ​ | $ Change | ​ ​ ​ | % Change

Total operating revenues | ​ | $ | 1,013,177 | ​ | $ | 948,455 | ​ | $ | 64,722 |  | 6.8 | %

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, providing maintenance services to other airlines and providing airport counter, gate and ramp services.

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

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | For the three months ended March 31,
​ | ​ | 2026 | ​ | 2025 | ​ | $ Change | ​ | % Change

Capacity purchase agreements aircraft lease revenue | ​ |  | 175,828 | ​ |  | 146,027 | ​ |  | 29,801 |  | 20.4 | %
Prorate agreements and SWC revenue | ​ |  | 168,188 | ​ | ​ | 130,814 | ​ | ​ | 37,374 |  | 28.6 | %
Flying agreements revenue | ​ | $ | 977,885 | ​ | $ | 915,994 | ​ | $ | 61,891 |  | 6.8 | %

Combined “Capacity purchase agreements flight operations revenue” and “Capacity purchase agreements aircraft lease revenue” increased 3.1% for the three months ended March 31, 2026, compared to the three months ended March 31, 2025, driven primarily by a 3.1% increase in block hour production during the three months ended March 31, 2026, compared to the three months ended March 31, 2025. The increase in aircraft lease revenue and decrease in flight operations revenue was primarily due to a reallocation of variable consideration between non-lease and lease components based on relative standalone selling prices as a result of capacity purchase agreement contract amendments entered into since March 31, 2025.

The increase in prorate agreements and SWC revenue of $37.4 million, or 28.6%, for the three months ended March 31, 2026, compared to the three months ended March 31, 2025, was primarily due to an increase in prorate departures, passengers and passenger revenue we received on routes we operated under our prorate agreements during the three months ended March 31, 2026, compared to the three months ended March 31, 2025.

The increase in lease, airport services and other revenues of $2.8 million, or 8.7%, for the three months ended March 31, 2026, compared to the three months ended March 31, 2025, was primarily due to an increase in the number of

leased assets and an increase in lease rates during the three months ended March 31, 2026, compared to the three months ended March 31, 2025.

Operating Expenses

Individual expense components attributable to our operations are set forth in the following table (dollar amounts in thousands):

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | For the three months ended March 31,
​ | ​ | 2026 | ​ | 2025 | ​ | $ Change | ​ | % Change
Salaries, wages and benefits | ​ | $ | 422,104 | ​ | $ | 377,311 | ​ | $ | 44,793 | ​ | 11.9 | %

Total operating expenses | ​ | $ | 889,491 | ​ | $ | 809,078 | ​ | $ | 80,413 |  | 9.9 | %

Salaries, wages and benefits. The $44.8 million, or 11.9%, increase in salaries, wages and benefits for the three months ended March 31, 2026, compared to the three months ended March 31, 2025, was primarily due to an increase in direct labor costs supporting the higher number of flights we operated during the three months ended March 31, 2026, compared to the three months ended March 31, 2025, and due to an increase in pilot training costs associated with higher attrition rates since March 31, 2025.

Aircraft maintenance, materials and repairs. The $3.9 million, or 1.9%, increase in aircraft maintenance expense for the three months ended March 31, 2026, compared to the three months ended March 31, 2025, was primarily due to an increase in our flight volume, which increased our maintenance activity and related expenses for the three months ended March 31, 2026, compared to the three months ended March 31, 2025.

Depreciation and amortization. The $0.8 million, or 0.9%, increase in depreciation and amortization expense for the three months ended March 31, 2026, compared to the three months ended March 31, 2025, was primarily due to an increase in depreciation expense related to the acquisition of eight new E175 aircraft and spare engines since March 31, 2025, offset by certain CRJ aircraft and engines that were depreciated to their estimated residual value since March 31, 2025.

Airport-related expenses. Airport-related expenses include airport-related customer service costs such as outsourced airport gate and ramp agent services, airport security fees, passenger interruption costs, deicing, landing fees and station rents. The $8.3 million, or 30.0%, increase in airport-related expenses for the three months ended March 31, 2026, compared to the three months ended March 31, 2025, was primarily due to an increase in subcontracted airport services, station rents, weather-related aircraft deicing costs and landing fees as a result of an increase in the number of flights we operated under our prorate agreements. For clarity, our employee airport customer service labor costs are reflected in salaries, wages and benefits and customer service labor costs we outsource to third parties are included in airport-related expenses.

Aircraft fuel. The $14.4 million, or 58.9%, increase in fuel cost for the three months ended March 31, 2026, compared to the three months ended March 31, 2025, was primarily due to an increase in the number of flights we operated under our prorate agreements and under SWC and the corresponding increase in gallons of fuel we purchased, and an increase in our average fuel cost per gallon from $3.03 for the three months ended March 31, 2025 to $3.40 for the three months ended March 31, 2026. We purchase and incur expense for all fuel on flights operated under our prorate agreements and SWC. All fuel costs incurred under our capacity purchase agreements are either purchased directly by our major airline partner, or if purchased by us, we record the direct reimbursement as a reduction to our fuel expense. The following table summarizes the gallons of fuel we purchased under our prorate agreements and SWC, for the periods indicated:

Fuel expense | ​ | $ | 38,904 | ​ | $ | 24,488 |  | 58.9 | %

Other operating expenses. Other operating expenses primarily consist of aircraft rentals, property taxes, hull and liability insurance, simulator costs, crew per diem, crew hotel costs and credit loss reserves. The $8.2 million, or 10.1%, increase in other operating expenses was primarily due to higher training‑related hotel costs, driven by pilot training, and an increase in other operating costs as a result of the higher number of flights we operated during the three months ended March 31, 2026, compared to the three months ended March 31, 2025.

Summary of interest expense, interest income, other expense, net and provision for income taxes

Interest expense. The $2.7 million, or 9.8%, decrease in interest expense for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025 was primarily related to a decrease in outstanding debt. At March 31, 2026 we had $2.4 billion of outstanding debt, compared to $2.6 billion at March 31, 2025. Our average effective interest rate for the three months ended March 31, 2026 and 2025, was 4.4% and 4.3%, respectively.

Interest income. Interest income decreased $1.5 million, from $10.1 million for the three months ended March 31, 2025, to $8.6 million for the three months ended March 31, 2026. The decrease in interest income was primarily related to a decrease in interest rates on our marketable securities from March 31, 2025 to March 31, 2026.

Other expense, net. Other expense, net of income decreased $1.6 million for the three months ended March 31, 2026, compared to the three months ended March 31, 2025. Other expense, net primarily consists of the unrealized and realized gains and losses on our investments in other companies, income or loss related to our equity method investments and gains or losses on the sale of assets. The decrease in other expense, net of income was primarily the result of a smaller decrease in the fair value of our investments in other companies for the three months ended March 31, 2026, compared to the three months ended March 31, 2025.

​

Provision for income taxes. For the three months ended March 31, 2026 and 2025, our effective income tax rates were 5.6% and 16.7%, respectively, which included the statutory federal income tax rate of 21% and other reconciling income tax items, including state income taxes, the impact of non-deductible expenses and a discrete tax benefit on employee equity awards that vested during the period. The decrease in the effective tax rate was primarily related to a higher discrete tax benefit from additional tax deductions generated from employee equity awards that vested for the three months ended March 31, 2026, compared to the three months ended March 31, 2025.

Net income. Primarily due to the factors described above, we generated net income of $101.7 million, or $2.50 per diluted share, for the three months ended March 31, 2026, compared to net income of $100.6 million, or $2.42 per diluted share, for the three months ended March 31, 2025.

Liquidity and Capital Resources

As of March 31, 2026, we had $627.3 million in cash and cash equivalents and marketable securities. As of March 31, 2026, we had $75.4 million available for borrowings under our line of credit. Given our available liquidity as of March 31, 2026, we believe the working capital currently available to us will be sufficient to meet our present financial requirements, including planned capital expenditures, scheduled lease payments and debt service obligations for at least the next 12 months.

Our total cash, cash equivalents and marketable securities decreased from $706.9 million as of December 31, 2025 to $627.3 million as of March 31, 2026, or by $79.6 million. Our total long-term debt, including current maturities, was $2.4 billion as of both March 31, 2026 and December 31, 2025. Additionally, during the three months ended March 31, 2026, we repurchased 782,900 shares of our common stock for $75.3 million under a share repurchase program authorized by our Board of Directors. At March 31, 2026, our total capital mix (measured as a ratio of total stockholder equity and total long-term debt, including current maturities) was 53.3% equity and 46.7% total long-term debt, compared to 53.4% equity and 46.6% total long-term debt at December 31, 2025.

As of March 31, 2026, and December 31, 2025, we had $47.5 million and $47.2 million, respectively, in letters of credit and surety bonds outstanding with various banks and surety institutions. We had no restricted cash as of March 31, 2026, and December 31, 2025.

Cash Flows provided by Operating Activities

Our cash flows provided by operating activities was $144.5 million for the three months ended March 31, 2026, compared to $171.0 million for the three months ended March 31, 2025. Our operating cash flows are typically impacted by various factors including our net income, adjusted for non-cash expenses and gains such as depreciation expense, stock-based compensation expense and gains or losses on the disposal of assets; and timing of cash payments and cash receipts attributed to our various current asset and liability accounts, such as accounts receivable, inventory, accounts payable, income taxes, accrued liabilities, deferred revenue and unbilled revenue.

The decrease in our cash flow from operations for the three months ended March 31, 2026, compared to the three months ended March 31, 2025, was primarily due to a decrease in income before income taxes for the three months ended March 31, 2026, compared the three months ended March 31, 2025, and an increase in accounts payable due to the timing of cash payments for the comparable periods.

Cash Flows used in Investing Activities

Our cash flows used in investing activities was $82.8 million for the three months ended March 31, 2026, compared to cash flows used in investing activities of $66.1 million for the three months ended March 31, 2025. Our investing cash flows are typically impacted by various factors including our capital expenditures, such as the acquisition of aircraft and spare engines; deposit payments and refunds of previously made deposits on new aircraft; purchase and sales of marketable securities; proceeds from the sale of assets; and timing of cash payments and cash receipts attributed to our various long-term asset and long-term liability accounts.

Excluding the purchase and sale of marketable securities, which results in the transfer of dollars between our investments in marketable securities and our cash accounts, our cash used in investing activities increased from $68.4 million for the three months ended March 31, 2025, to $105.0 million for the three months ended March 31, 2026. Excluding the transfer of dollars between our investments in marketable securities and our cash accounts, the remaining increase in cash used in investing activities was primarily due to an increase of $29.0 million used in the acquisition of property and equipment for the three months ended March 31, 2026, compared to the three months ended March 31, 2025, primarily due to the acquisition of one new E175 aircraft and spare engines during the three months ended March 31, 2026.

Cash Flows used in Financing Activities

Our cash flows used in financing activities was $118.5 million for the three months ended March 31, 2026, compared to cash used in financing activities of $153.3 million for the three months ended March 31, 2025. Our

financing cash flows are typically impacted by various factors including proceeds from issuance of debt, principal payments on debt obligations and repurchases of our common stock.

The $34.8 million decrease in cash used in financing activities for the three months ended March 31, 2026, compared to the three months ended March 31, 2025, was primarily due to an increase of $115.0 million in proceeds from the issuance of long-term debt for the purchase of one new E175 aircraft and engine financings, net of principal payments on long-term debt, offset by an increase of $18.4 million in cash used for employee income taxes paid on vested equity awards in lieu of shares and an increase of $61.7 million in cash used to purchase treasury stock during the three months ended March 31, 2026, compared to the three months ended March 31, 2025.

Significant Commitments and Obligations

General

See Note 7, “Leases, Commitments, Guarantees and Contingencies,” to the condensed consolidated financial statements for our commitments and obligations for each of the next five years and thereafter.

Purchase Commitments and Options

As of March 31, 2026, we had a firm purchase commitment for 68 new E175 aircraft from Embraer with delivery dates anticipated into 2032.

At the time of each aircraft acquisition, we evaluate the financing alternatives available to us, and select one or more of these methods to fund the acquisition. In recent years, we have issued long-term debt to finance our new aircraft. At present, we intend to fund our aircraft purchase commitments through a combination of cash on hand and debt financing. Based on current market conditions and discussions with prospective leasing organizations and financial institutions, we currently believe that we will be able to obtain financing for our committed acquisitions, as well as additional aircraft. We intend to finance the firm purchase commitment for 68 E175 aircraft with approximately 75-85% debt and the remaining balance with cash.

Aircraft Lease and Facility Obligations

We also have long-term lease obligations, primarily relating to our facilities, aircraft and engines. Excluding aircraft financed by our major airline partners that we operate for them under contract, we had eight aircraft under lease with remaining terms ranging from three years to four years as of March 31, 2026. These eight leased aircraft are subleased to a third party. Future minimum lease payments due under all long-term operating leases were approximately $119.4 million at March 31, 2026. Assuming a 6.2% discount rate, which is the average incremental borrowing rate we anticipate we would have incurred on debt obtained over a similar term to acquire these assets, the present value of these lease obligations would have been equal to approximately $82.9 million at March 31, 2026.

Long-term Debt Obligations

As of March 31, 2026, we had $2.4 billion of long-term debt, which consisted of $2.2 billion of debt used to finance aircraft and spare engines and $200.6 million of unsecured debt payable to the U.S. Department of the Treasury (“Treasury”). The average effective interest rate on our debt obligations was approximately 4.4% at March 31, 2026.

Under our capacity purchase agreements, our major airline partners compensate us for our costs of the aircraft on a monthly basis. The consideration for aircraft ownership costs we receive varies by agreement but is intended to compensate us for our ownership of the aircraft while the aircraft is under contract.

Guarantees

We have guaranteed the obligations of SkyWest Airlines under the United Express Agreement and the Delta Connection Agreement for the E175 aircraft. In addition, we have guaranteed certain other obligations under our aircraft financing and leasing agreements.

Table of Contents

We have guaranteed $12.2 million in promissory notes of a third party in the event the third party defaults on its payments. The third party’s loans are secured by aircraft and engines.

Seasonality

Our results of operations for any interim period are not necessarily indicative of those for an entire year, because the airline industry is subject to seasonal fluctuations and general economic conditions. Our operations are somewhat favorably affected by increased travel on our prorate routes, historically occurring during the summer months, and unfavorably affected by decreased travel during the months of November through February and by inclement weather, which may occasionally or frequently, depending on the severity of the inclement weather in any given winter, result in cancelled flights during the winter months.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes in market risk from the information provided in Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk, in our Annual Report on Form 10-K for the year ended December 31, 2025, except as follows:

Aircraft Fuel

In the past, we have not experienced sustained material difficulties with fuel availability, and we currently expect to be able to obtain fuel at prevailing prices in quantities sufficient to meet our future needs. Pursuant to our capacity purchase agreements, United, Delta, American and Alaska have agreed to bear the economic risk of fuel price fluctuations on our contracted flights. We bear the economic risk of fuel price fluctuations on our prorate and SWC operations. For the three months ended March 31, 2026, approximately 17.2% of our total flying agreements revenue was derived from prorate agreements and SWC. For the three months ended March 31, 2026, the average price per gallon of aircraft fuel was $3.40. For illustrative purposes only, we have estimated the impact of the market risk of fuel price fluctuations on our prorate and SWC operations using a hypothetical increase of 25% in the price per gallon we purchase. Based on this hypothetical assumption, we would have incurred an additional $9.7 million in fuel expense for the three months ended March 31, 2026.

ITEM 4. CONTROLS AND PROCEDURES

​

Disclosure Controls and Procedures

​

Our management, including our Chief Executive Officer and Chief Financial Officer, performed an evaluation of our disclosure controls and procedures, which have been designed to ensure that information we are required to disclose in the reports we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported, accurately and within the time periods specified in the rules and forms of the SEC. Our management, including our Chief Executive Officer and Chief Financial Officer, concluded that, as of March 31, 2026, those controls and procedures were effective to ensure that information we are required to disclose in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

​
