**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, 2024. The results of operations for the three and nine months ended September 30, 2025, are not necessarily indicative of the results that may be expected for the year ending December 31, 2025.

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 December 2023, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update No. 2023-09, "Income Taxes (ASC Topic 740) – Improvements to Income Tax Disclosures", which enhances the transparency, effectiveness and comparability of income tax disclosures by requiring consistent categories and greater disaggregation of information related to income tax rate reconciliations and the jurisdictions in which income taxes are paid. The guidance is effective for annual periods beginning after December 15, 2024, 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.

In March 2024, the FASB issued ASU No. 2024-03, "Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (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

[**Table of Contents**](#Toc)

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 nine months ended September 30, 2025 and 2024, capacity purchase agreements represented approximately 84.8% and 86.8% 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 airline 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 nine months ended September 30, 2025 and 2024, prorate agreements and SWC revenue represented approximately 15.2% and 13.2% of the Company's flying agreements revenue, respectively.

The following table represents the Company's flying agreements revenue by type for the three and nine months ended September 30, 2025 and 2024 (in thousands):

|  | **2025** | **2024** | **2025** | **2024** |
| Capacity purchase agreements flight operations revenue (non-lease component) | $672559 | $624342 | $1994660 | $1763629 |
| Capacity purchase agreements fixed aircraft lease revenue | 91036 | 75084 | 306244 | 225374 |
| Capacity purchase agreements variable aircraft lease revenue | 80600 | 61308 | 170537 | 180035 |
| Prorate agreements and SWC revenue | 167089 | 122760 | 443348 | 330915 |
| Flying agreements revenue | $1011284 | $883494 | $2914789 | $2499953 |

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. During the nine months ended September 30, 2025, the Company recognized $28.8 million of previously deferred revenue associated with the non-lease fixed monthly payments under certain agreements and increased unbilled revenue by $9.5 million under certain other agreements,

[**Table of Contents**](#Toc)

compared to recognizing $24.5 million of previously deferred revenue and decreasing unbilled revenue by $0.9 million during the nine months ended September 30, 2024.

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 cover either the Company's aircraft principal and interest debt service costs, its aircraft depreciation and interest expense or its aircraft lease expense costs while the aircraft is under 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 recognized $10.5 million of previously deferred lease revenue and increased unbilled lease revenue by $4.2 million during the nine months ended September 30, 2025, whereas the Company recognized $1.5 million of deferred lease revenue during the nine months ended September 30, 2024, under the straight-line basis. 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 Company's total deferred revenue balance as of September 30, 2025 was $297.1 million, including $133.8 million in other current liabilities and $163.3 million in other long-term liabilities. The Company's unbilled revenue balance was $27.7 million as of September 30, 2025, including $1.1 million in other current assets and $26.6 million in other long-term assets. The Company's total deferred revenue balance was $337.5 million as of December 31, 2024, including $54.8 million in other current liabilities and $282.7 million in other long-term liabilities. The Company's unbilled revenue balance was $15.1 million as of December 31, 2024, including $1.1 million in other current assets and $14.0 million in other long-term assets.

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 September 30, 2025, the Company had 498 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"), including a 50-seat configuration of the CRJ700 aircraft, commonly referred to as a "CRJ550," and Canadair CRJ200 regional jet aircraft ("CRJ200"). The following table summarizes the significant provisions of each code-share agreement the Company has with each major airline partner through SkyWest Airlines:

\* 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 September 30, 2025, 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 13 new E175 aircraft. Three new E175 aircraft are currently scheduled for delivery in the fourth quarter of 2025 and ten new E175 aircraft are scheduled for delivery in 2026. The Company anticipates financing the aircraft through debt.

● Capacity purchase agreement with Alaska for one new E175 aircraft. The delivery date for the new E175 aircraft is currently scheduled for 2026. The Company anticipates financing the aircraft through debt.

● 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 agreements with United for 29 CRJ550 aircraft that are anticipated to be placed into service between the fourth quarter of 2025 and the end of 2026. Pursuant to these agreements, the Company is in the process of converting its 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

[**Table of Contents**](#Toc)

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 and nine months ended September 30, 2025 and 2024 (in thousands):

| Total future minimum rental income under operating leases | $203314  |

---

Of the Company's $5.7 billion of property and equipment, net of accumulated depreciation, as of September 30, 2025, $241.7 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 September 30, 2025, the Company had gross receivables of $149.5 million in current assets and gross receivables of $257.8 million in other long-term assets. As of December 31, 2024, the Company had gross receivables of $125.9 million in current assets and gross receivables of $225.2 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

[**Table of Contents**](#Toc)

respective accounts receivable, notes receivable or guarantees. During the nine months ended September 30, 2025, the Company increased its credit loss reserve as a result of the Company's assessment of higher credit risk of certain outstanding receivables.

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

**(3) Capital Transactions**

***Stock-Based Compensation***

During the nine months ended September 30, 2025, the Company granted 25,359 restricted stock units and 59,165 performance shares to certain employees of the Company under the SkyWest, Inc. Amended and Restated 2019 Long-Term Incentive Plan. Both the restricted stock units and 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 2025 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. Upon vesting, each restricted stock unit and performance share will be replaced with one share of common stock. The weighted average fair value of these restricted stock units and performance shares on their date of grant was $118.96 per share.

Additionally, during the nine months ended September 30, 2025, the Company granted 6,275 fully vested shares of common stock and 1,255 fully vested restricted stock units to the Company's directors at a weighted average grant date fair value of $97.02.

The Company accounts for forfeitures of restricted stock units and performance shares when forfeitures occur. The estimated fair value of the restricted stock units and performance shares 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 nine months ended September 30, 2025 and 2024, the Company recorded pre-tax stock-based compensation expense of $14.5 million and $15.1 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 million increase to the existing repurchase program. Following such increase, at September 30, 2025, $240.0 million remained available under the repurchase program.

During the nine months ended September 30, 2025, the Company repurchased 580,257 shares of common stock for $57.6 million at a weighted average price per share of $99.23. The Company also recorded $0.2 million of excise tax related to the stock repurchases as treasury stock in the Company's Stockholders' Equity for the nine months ended September 30, 2025. During the nine months ended September 30, 2024, the Company repurchased 530,812 shares of common stock for $38.4 million at a weighted average price per share of $72.30 and recorded $0.3 million of excise tax related to the stock repurchases as treasury stock in the Company's Stockholders' Equity.

**(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

[**Table of Contents**](#Toc)

("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 nine months ended September 30, 2025 and 2024, 161,000 and 336,000 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 September 30, 2025 and 2024, 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 operating new aircraft financed through the issuance of debt, including the Company's E175 fleet, separately from the profitability of the Company's capital deployed for ownership and financing of such aircraft. 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. Additionally, aircraft removed from SkyWest Airlines' operations and held for sale are included in the SkyWest Leasing segment.

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 measure when assessing performance of the segment and monitors budget versus actual results to allocate resources for each segment predominantly in the annual budget and forecasting process.

The following represents the Company's segment data for the three-month periods ended September 30, 2025 and 2024 (in thousands). As required by the adoption of ASC 2023-07, "Segment Reporting (ASC Topic 280) – Improvements to Reportable Segment Disclosures," the Company recast the segment disclosures for the three and nine months ended September 30, 2024 to conform to the current year presentation.

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 balance of the debt under the guarantee was $13.0 million as of September 30, 2025.

[**Table of Contents**](#Toc)

In 2023, the Company agreed to guarantee up to $12.0 million of debt for an aviation school. The debt was secured by the school's aircraft and engines and had a five-year term. In exchange for providing the guarantee, the Company received 2.0% of the guaranteed amount annually as consideration in cash. In June 2025, the aviation school fully repaid the debt under the guarantee agreement. As a result, the Company was no longer a guarantor at September 30, 2025.

The purpose of these guarantees is to help reduce the financing costs of aircraft for the third parties in an effort to increase the potential number of commercial pilots in the Company's hiring pipeline. The Company also 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. |

("Regional One") and, as of September 30, 2025, 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 September 30, 2025. As of September 30, 2025 and December 31, 2024, the Company's investment balance in Aero Engines was $12.5 million and $23.9 million, respectively, and has been recorded in "Other Assets" on the Company's consolidated balance sheet.

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 nine months ended September 30, 2025, the Company recorded income of $1.4 million, its portion of income generated by Contour, which was recorded in "Other income (expense), net" on the Company's consolidated statements of comprehensive income.

During the nine months ended September 30, 2024, the Company recorded a net loss of $6.6 million in "Other income (expense), net" on the Company's consolidated statements of comprehensive income, including a realized gain of $3.4 million from the exercise of the put option, a realized loss of $1.4 million from the forfeited shares of Eve common stock and unrealized losses of $8.6 million related to the Eve Investments. As of September 30, 2025 and December 31, 2024, the fair value of the Eve Investments was $5.7 million and $8.2 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 nine months ended September 30, 2025 was 23.5%. The Company's effective tax rate for the nine months ended September 30, 2025 varied from the federal statutory rate of 21.0% primarily due to the provision for state income taxes and the impact of non-deductible expense, partially offset by a discrete tax benefit from additional tax deductions generated from employee equity awards that vested during the nine months ended September 30, 2025.

The Company's effective tax rate for the nine months ended September 30, 2024 was 24.4%. The Company's effective tax rate for the nine months ended September 30, 2024 varied from the federal statutory rate of 21.0% primarily due to the provision for state income taxes and the impact of non-deductible expenses. This was partially offset by a discrete tax benefit from additional tax deductions generated from employee equity awards that vested during the nine months ended September 30, 2024, a discrete tax benefit from the release of a previously recorded uncertain tax position liability and a discrete tax benefit from a release of the valuation allowance on state net operating losses anticipated to be utilized prior to expiration.

On July 4, 2025, the One Big Beautiful Bill Act was signed into law. The legislation did not have a material impact on our income tax expense for the quarter ended September 30, 2025, and we do not expect it to materially change our effective income tax rate for the year ending December 31, 2025.

**Overview**

We have the largest regional airline operation in the United States through our operating subsidiary SkyWest Airlines, Inc. ("SkyWest Airlines"). As of September 30, 2025, we offered scheduled passenger and air freight service with approximately 2,400 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. During 2022, we formed SkyWest Charter, LLC ("SWC"), which offers on-demand charter services using CRJ200 aircraft in a 30-seat configuration. As of September 30, 2025, we had 634 total aircraft in our fleet, including 498 aircraft in scheduled service or under contract pursuant to our code-share agreements, summarized as follows:

---

| &nbsp;&nbsp;Total Fleet | 265 | 54 | 177 | 138 | 634 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) As of September 30, 2025, other aircraft included: supplemental spare aircraft supporting our code-share agreements that may be placed under future code-share or leasing agreements, aircraft transitioning between code-share agreements with our major airline partners or aircraft that are scheduled to be disassembled for use as spare parts.

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 September 30, 2024, to September 30, 2025, we made changes to our fleet, including the addition of six 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 13 new E175 aircraft with United between the fourth quarter of 2025 and the end of 2026, 16 new E175 aircraft with Delta from 2027 to 2028 (which are expected to replace 11 CRJ900s and five CRJ700s SkyWest is currently flying under contract with Delta) and one new E175 aircraft with Alaska in 2026. We also have multiple agreements with United to place 29 used CRJ550 aircraft into service between the fourth quarter of 2025 and the end of 2026. Timing of placing these additional aircraft into service, including delivery timing on acquired aircraft, may be subject to change as we are coordinating with our

[**Table of Contents**](#Toc)

major airline partners in response to labor availability or other factors. Our primary objective in the fleet changes is to improve our profitability by adding new E175 aircraft and used CRJ700, CRJ550 and CRJ900 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.

As of September 30, 2025, approximately 44.8% of our aircraft in scheduled service or under contract were operated for United, approximately 28.3% were operated for Delta, approximately 18.5% were operated for American and approximately 8.4% 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 capacity purchase agreements and prorate agreements. For the nine months ended September 30, 2025, our capacity purchase revenue represented approximately 84.8% of our total flying agreements revenue and our prorate and SWC revenue, combined, represented approximately 15.2% 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.

**Third Quarter Summary** 

We had total operating revenues of $1.1 billion for the three months ended September 30, 2025, a 15.0% increase compared to total operating revenues of $912.8 million for the three months ended September 30, 2024. We had net income of $116.4 million, or $2.81 per diluted share, for the three months ended September 30, 2025, compared to net income of $89.7 million, or $2.16 per diluted share, for the three months ended September 30, 2024. The significant items affecting our revenue and operating expenses during the three months ended September 30, 2025, 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 484 as of September 30, 2024 to 498 as of September 30, 2025, or by 2.9%; and the number of block hours increased from 334,459 for the three months ended September 30, 2024 to 384,247 for the three months ended September 30, 2025, or by 14.9%, due to an increase in the number of aircraft operating under our capacity purchase agreements and an increase in the scheduled daily utilization of our aircraft driven by an increase in the number of available captains. As of the date of this Quarterly Report on Form 10-Q, the Company believes its scheduled aircraft utilization is no longer constrained by the number of available captains.

Our capacity purchase revenue increased $83.5 million, or 11.0%, for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024, 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 $44.3 million, or 36.1%, for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024.

*Operating Expenses*

Our total operating expenses increased $94.5 million, or 12.1%, for the three months ended September 30, 2025, compared to the three months ended September 30, 2024. The increase in operating expenses was primarily due to an increase in our direct operating expenses associated with the increase in the number of flights we operated for the

[**Table of Contents**](#Toc)

three months ended September 30, 2025, compared to the three months ended September 30, 2024. Departures increased from 201,397 for the three months ended September 30, 2024 to 226,305 for the three months ended September 30, 2025, or by 12.4%, and our total block hours increased 14.9% for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. 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, 2024, 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, 2024. 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 nine months ended September 30, 2025.

**Recent Accounting Pronouncements**

**Results of Operations**

**Three Months Ended September 30, 2025 and 2024**

*Operational Statistics*

The following table sets forth our major operational statistics and the associated percentage changes for the periods identified below. The increase in block hours, departures and passengers carried during the three months ended September 30, 2025, compared to the three months ended September 30, 2024, was primarily due to additional aircraft operating under our capacity purchase agreements and an increase in the number of block hours incurred per aircraft as the number of available captains did not limit our flight schedules during the three months ended September 30, 2025, compared to the three months ended September 30, 2024, which allowed for a higher scheduled utilization of our aircraft.

| Total operating revenues | $1050029 | $912786 | $137243 | 15.0% |

---

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, maintenance services provided to third parties and providing airport counter, gate and ramp services.

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

| Prorate agreements and SWC revenue | 167089 | 122760 | 44329 | 36.1% |
| Flying agreements revenue | $1011284 | $883494 | $127790 | 14.5% |

---

The increase in "Capacity purchase agreements flight operations revenue" of $48.2 million, or 7.7%, was primarily due to an increase in block hour production from aircraft under our capacity purchase agreements, offset by a decrease in the recognition of revenue that was previously deferred related to fixed monthly payments for flight operations received under our capacity purchase agreements for the three months ended September 30, 2025, compared to the three months ended September 30, 2024. Under our capacity purchase agreements, we are paid a fixed amount per month per aircraft over the contract term. We recognize the total projected fixed monthly payments per aircraft as revenue proportionately to the number of block hours we complete for each reporting period, relative to the estimated number of block hours we anticipate completing over the remaining contract term. Under our capacity purchase agreements, the performance obligation of each completed flight is measured in block hours incurred for each completed flight. Based on the number of completed block hours during the three months ended September 30, 2025, we recognized $11.3 million of previously deferred revenue, net of unbilled revenue, related to the non-lease fixed monthly payments we received associated with our flight operations revenues. For the three months ended September 30, 2024, we recognized $18.2 million of previously deferred revenue, net of unbilled revenue, related to non-lease fixed monthly payments received associated with our flight operations revenues. The timing of our revenue recognition related to the fixed payments associated with our flight operations will be adjusted over the remaining contract term for each capacity

purchase agreement based on the number of block hours we complete each reporting period relative to the number of block hours we anticipate completing over the remaining contract term of each capacity purchase agreement.

The increase in "Capacity purchase agreements aircraft lease revenue" of $35.2 million, or 25.8%, was primarily due to the addition of aircraft under our capacity purchase agreements from September 30, 2024 and a contract extension that reallocated certain fixed monthly lease revenue from flight operations revenue under one of our capacity purchase agreements in 2025 based on relative standalone selling prices of the lease and non-lease components. Under our capacity purchase agreements, a portion of the consideration we are paid is designed as reimbursement for certain aircraft ownership costs and is considered lease revenue, including fixed monthly payments and variable payments. We recognize the fixed monthly lease payments as lease revenue using the straight-line basis over the capacity purchase agreement term and variable lease payments are recognized in the period when the block hours are completed. Additionally, we recognized $5.8 million of previously deferred lease revenue, net of unbilled revenue, during the three months ended September 30, 2025, using the straight-line basis for fixed monthly lease payments, compared to recognizing $0.5 million of previously deferred revenue, net of unbilled revenue, during the three months ended September 30, 2024.

The deferred revenue balance applicable to each contract will be recorded as revenue over the term of each respective contract. For clarity, under our "Capacity purchase agreements flight operations revenue" and "Capacity purchase agreements aircraft lease revenue" combined, we recognized $17.1 million of previously deferred revenue, net of unbilled revenue, during the three months ended September 30, 2025, compared to recognizing $18.7 million of deferred revenue, net of unbilled revenue, during the three months ended September 30, 2024. Our total deferred revenue balance associated with our "Capacity purchase agreements flight operations revenue" and our "Capacity purchase agreements aircraft lease revenue," net of unbilled revenue, was $269.4 million as of September 30, 2025, compared to total deferred revenue, net of unbilled revenue, of $322.4 million as of December 31, 2024.

The increase in prorate agreements and SWC revenue of $44.3 million, or 36.1%, was primarily due to an increase in prorate passengers and passenger revenue we received on routes we operated under our prorate agreements during the three months ended September 30, 2025, compared to the three months ended September 30, 2024. The increase in prorate passengers as compared to the prior year period was primarily driven by an increase in departures due to the improvement in the number of available captains during the three months ended September 30, 2025.

The increase in lease, airport services and other revenues of $9.5 million, or 32.3%, for the three months ended September 30, 2025, compared to the three months ended September 30, 2024, was primarily due to an increase in revenue from maintenance services provided to third parties.

*Operating Expenses*

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

---

*Salaries, wages and benefits.* The $14.2 million, or 3.8%, increase in salaries, wages and benefits was primarily due to an increase in direct labor costs that resulted from the higher number of flights we operated, partially offset by operating efficiencies from higher utilization of our aircraft, during the three months ended September 30, 2025, compared to the three months ended September 30, 2024.

[**Table of Contents**](#Toc)

*Aircraft maintenance, materials and repairs.* The $66.3 million, or 36.5%, increase in aircraft maintenance expense was primarily due to incremental maintenance costs incurred on our CRJ fleet, an increase in our flight volume, which increased our maintenance activity and related expenses, and maintenance services provided to third parties for the three months ended September 30, 2025, compared to the three months ended September 30, 2024.

*Depreciation and amortization.* The $4.2 million, or 4.3%, decrease in depreciation and amortization expense was primarily a result of extending the estimated useful lives on our CRJ700/CRJ550 fleet by an average of three years and revising the residual values of the assets accordingly during the fourth quarter of 2024, offset by an increase in depreciation expense related to the acquisition of six new E175 aircraft and spare engines since September 30, 2024.

*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 $9.2 million, or 40.8%, increase in airport-related expenses for the three months ended September 30, 2025, compared to the three months ended September 30, 2024, was primarily due to an increase in subcontracted airport services, station rents 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 $11.5 million, or 50.6%, increase in fuel cost 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, offset by a decrease in our average fuel cost per gallon from $3.10 for the three months ended September 30, 2024 to $3.04 for the three months ended September 30, 2025. 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 gallons purchased | 11270 | 7336 | 53.6% |
| Fuel expense | $34216 | $22724 | 50.6% |

---

*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 $2.5 million, or 3.2%, decrease in other operating expenses was primarily related to a decrease in simulator and other training costs attributed to a reduction in newly hired pilots, partially offset by an increase in other operating costs, such as crew per diem and crew hotel costs, as a result of the higher number of flights we operated during the three months ended September 30, 2025, compared to the three months ended September 30, 2024.

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

*Interest Expense.* Interest expense decreased $2.2 million, or 7.9%, for the three months ended September 30, 2025 as compared to the three months ended September 30, 2024. The decrease in interest expense was primarily related to a decrease in outstanding debt. At September 30, 2025 we had $2.4 billion of outstanding debt, compared to $2.7 billion at September 30, 2024. Our average effective interest rate for the three months ended September 30, 2025 and 2024, was 4.3% and 4.1%, respectively.

*Interest income.* Interest income decreased $1.9 million, from $12.5 million for the three months ended September 30, 2024, to $10.6 million for the three months ended September 30, 2025. The decrease in interest income was primarily related to a decrease in interest rates on our marketable securities from September 30, 2024 to September 30, 2025.

[**Table of Contents**](#Toc)

*Other income (expense), net.* Other income, net of expenses decreased $2.0 million during the three months ended September 30, 2025, compared to the three months ended September 30, 2024. Other income (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 income, net of expenses was primarily a result of a decrease in the fair value of our investments in other companies, offset by gains on the sale of assets for the three months ended September 30, 2025, compared to the three months ended September 30, 2024.

*Provision for income taxes.* For the three months ended September 30, 2025 and 2024, our effective income tax rates were 26.0% and 22.8%, respectively, which included the statutory federal income tax rate of 21% and other reconciling income tax items, including state income taxes, and the impact of non-deductible expenses. The increase in the effective tax rate was primarily related to a discrete tax benefit from the release of a previously recorded uncertain tax position liability and a discrete tax benefit from a release of the valuation allowance on state net operating losses anticipated to be utilized prior to expiration for the three months ended September 30, 2024, compared to no benefits for such items for the three months ended September 30, 2025.

*Net income.* Primarily due to the factors described above, we generated net income of $116.4 million, or $2.81 per diluted share, for the three months ended September 30, 2025, compared to net income of $89.7 million, or $2.16 per diluted share, for the three months ended September 30, 2024.

**Nine Months Ended September 30, 2025 and 2024**

*Operational Statistics*

The following table sets forth our major operational statistics and the associated percentage changes for the periods identified below. The increase in block hours, departures and passengers carried during the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024, was primarily due to additional aircraft operating under our capacity purchase agreements and an increase in the number of block hours incurred per aircraft as the number of available captains did not limit our flight schedules during the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024, which allowed for a higher scheduled utilization of our aircraft.

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

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

|:---|:---|:---|:---|:---|
|  | **For the nine months ended September 30,**  | **For the nine months ended September 30,**  | **For the nine months ended September 30,**  | **For the nine months ended September 30,**  |

The increase in "Capacity purchase agreements flight operations revenue" of $231.0 million, or 13.1%, was primarily due to an increase in block hour production from aircraft under our capacity purchase agreements and an increase in the recognition of revenue that was previously deferred related to fixed monthly payments for flight operations received under our capacity purchase agreements for the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024. Under our capacity purchase agreements, we are paid a fixed amount per month per aircraft over the contract term. We recognize the total projected fixed monthly payments per aircraft as revenue proportionately to the number of block hours we complete for each reporting period, relative to the estimated number of block hours we anticipate completing over the remaining contract term. Under our capacity purchase agreements, the performance obligation of each completed flight is measured in block hours incurred for each completed flight. Based on the number of completed block hours during the nine months ended September 30, 2025, we recognized $38.3 million of previously deferred revenue, net of unbilled revenue, related to the non-lease fixed monthly payments we received associated with our flight operations revenues. For the nine months ended September 30, 2024, we recognized $23.6 million of previously deferred revenue, net of unbilled revenue, related to non-lease fixed monthly payments received associated with our flight operations revenues. The timing of our revenue recognition related to the fixed payments associated with our flight operations will be adjusted over the remaining contract term for each capacity purchase agreement based on the number of block hours we complete each reporting period relative to the number of block hours we anticipate completing over the remaining contract term of each capacity purchase agreement.

The increase in "Capacity purchase agreements aircraft lease revenue" of $71.4 million, or 17.6%, was primarily due to the addition of aircraft under our capacity purchase agreements from September 30, 2024 and a contract extension that reallocated certain fixed monthly lease revenue from flight operations revenue based on relative standalone selling prices of the lease and non-lease components under one of our capacity purchase agreements during the nine months ended September 30, 2025. Under our capacity purchase agreements, a portion of the consideration we are paid is designed as reimbursement for certain aircraft ownership costs and is considered lease revenue, including fixed monthly payments and variable payments. We recognize the fixed monthly lease payments as lease revenue using the straight-line basis over the capacity purchase agreement term and variable lease payments are recognized in the period when the block hours are completed. Additionally, we recognized $14.7 million of previously deferred lease revenue, net of unbilled revenue, during the nine months ended September 30, 2025, using the straight-line basis for fixed monthly lease payments, compared to recognizing $1.5 million of previously deferred revenue, net of unbilled revenue, during the nine months ended September 30, 2024.

The deferred revenue balance applicable to each contract will be recorded as revenue over the term of each respective contract. For clarity, under our "Capacity purchase agreements flight operations revenue" and "Capacity purchase agreements aircraft lease revenue" combined, we recognized $53.0 million of previously deferred revenue, net of unbilled revenue, during the nine months ended September 30, 2025, compared to recognizing $25.1 million of deferred revenue, net of unbilled revenue, during the nine months ended September 30, 2024.

The increase in prorate agreements and SWC revenue of $112.4 million, or 34.0%, was primarily due to an increase in prorate departures, passengers and passenger revenue we received on routes we operated under our prorate agreements driven by an improvement in the number of available captains during the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024. Additionally, a portion of the increase was attributed to

[**Table of Contents**](#Toc)

an increase in SWC revenue during the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

The increase in lease, airport services and other revenues of $35.4 million, or 42.3%, was primarily due to an increase in maintenance services provided to third parties, an increase in the number of leased assets, and an increase in lease rates during the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

*Operating Expenses*

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

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **For the nine months ended September 30,**  | **For the nine months ended September 30,**  | **For the nine months ended September 30,**  | **For the nine months ended September 30,**  |

| Total operating expenses | $2550063 | $2232937 | $317126 | 14.2% |

---

*Salaries, wages and benefits.* The $75.7 million, or 7.0%, increase in salaries, wages and benefits was primarily due to an increase in direct labor costs that resulted from the higher number of flights we operated, partially offset by operating efficiencies from higher utilization of our aircraft during the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

*Aircraft maintenance, materials and repairs.* The $185.6 million, or 36.4%, increase in aircraft maintenance expense was primarily due incremental maintenance costs incurred on our CRJ fleet, an increase in our flight volume, which increased our maintenance activity and related expenses, and an increase in maintenance service activities provided to third parties for the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

*Depreciation and amortization.* The $17.3 million, or 6.0%, decrease in depreciation and amortization expense was primarily a result of extending the estimated useful lives on our CRJ700/CRJ550 fleet by an average of three years and revising the residual values of the assets accordingly during the fourth quarter of 2024, offset by an increase in depreciation expense related to the acquisition of six new E175 aircraft and spare engines since September 30, 2024.

*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 $25.8 million, or 42.2%, increase in airport-related expenses for the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024, 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 $20.9 million, or 32.1%, increase in fuel cost 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, offset by a decrease in our average fuel cost per gallon from $3.30 for the nine months ended September 30, 2024 to $2.98 for the nine months ended September 30, 2025. 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:

*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 $26.3 million, or 11.8%, increase in other operating expenses was primarily related to an increase in our credit loss reserve as a result of our assessment of higher credit risk of certain outstanding receivables and an increase in other operating costs, such as crew per diem and crew hotel costs, as a result of the higher number of flights we operated during the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

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

*Interest Expense.* Interest expense decreased $7.3 million, or 8.4%, for the nine months ended September 30, 2025 as compared to the nine months ended September 30, 2024. The decrease in interest expense was primarily related to a decrease in outstanding debt. At September 30, 2025 we had $2.4 billion of outstanding debt, compared to $2.7 billion at September 30, 2024. Our average effective interest rate for the nine months ended September 30, 2025 and 2024, was 4.3% and 4.1%, respectively.

*Interest income.* Interest income decreased $4.4 million, from $36.1 million for the nine months ended September 30, 2024, to $31.7 million for the nine months ended September 30, 2025. The decrease in interest income was primarily related to a decrease in interest rates from September 30, 2024 to September 30, 2025.

*Other income (expense), net.* Other income, net of expenses increased $6.5 million during the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024. Other income (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 increase in other income, net of expenses was primarily a result of an increase in the fair value of our investments in other companies for the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

*Provision for income taxes.* For the nine months ended September 30, 2025 and 2024, our effective income tax rates were 23.5% and 24.4%, 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 nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

*Net income.* Primarily due to the factors described above, we generated net income of $337.2 million, or $8.14 per diluted share, for the nine months ended September 30, 2025, compared to net income of $225.6 million, or $5.44 per diluted share, for the nine months ended September 30, 2024.

*SkyWest Airlines and SWC Segment Profit.* SkyWest Airlines and SWC segment profit was $221.0 million for the nine months ended September 30, 2025, compared to $81.6 million for the nine months ended September 30, 2024.

SkyWest Airlines and SWC block hour production increased 18.2%, from 941,722 for the nine months ended September 30, 2024 to 1,112,671 for the nine months ended September 30, 2025, primarily due to additional aircraft operating under our capacity purchase agreements and an increase in the number of available captains, which allowed for a higher scheduled utilization of our aircraft. Significant items contributing to the SkyWest Airlines and SWC segment profit for the nine months ended September 30, 2025 are set forth below.

SkyWest Airlines and SWC operating revenues increased $446.6 million, or 21.1%, from the nine months ended September 30, 2024, to the nine months ended September 30, 2025, primarily as a result of an increase in block hour production during the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

SkyWest Airlines and SWC's salaries, wages and benefits expense increased $75.7 million, or 7.0%, primarily due to an increase in direct labor costs that resulted from the higher number of flights we operated, partially offset by operating efficiencies from higher utilization of our aircraft during the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

SkyWest Airlines and SWC's aircraft maintenance, materials and repairs expense increased $164.4 million, or 33.5%, primarily due to incremental maintenance costs incurred on our CRJ fleet and higher flight volume, which increased the maintenance activity and related expenses, for the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

SkyWest Airlines and SWC's depreciation and amortization expense increased $7.3 million, or 6.6%, primarily due to acquiring additional assets, including engines and CRJ550 aircraft since September 30, 2024.

SkyWest Airlines and SWC's interest expense decreased $0.8 million, or 8.0%, primarily due to a decrease in outstanding debt from September 30, 2024 to September 30, 2025.

SkyWest Airlines and SWC's other segment items increased $60.4 million, or 17.6%, primarily related to an increase in fuel costs, airport-related expenses, such as subcontracted airport services, station rents, weather-related aircraft deicing costs and landing fees and other operating costs, such as crew per diem and crew hotel costs, as a result of the higher number of flights we operated during the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Other segment items for SkyWest Leasing include other operating expenses consisting primarily of property taxes and credit loss reserves; aircraft rentals; interest income and other income (expense) , net.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Segment profit is equal to income before income taxes. As a result of adopting ASC 2023-07, we included interest income and other income (expense), net in the recast segment profit for each segment for the nine months ended September 30, 2024, consistent with the presentation for the nine months ended September 30, 2025.

*SkyWest Leasing Segment Profit.* SkyWest Leasing profit increased $3.0 million, or 1.4%, during the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024, primarily due to an increase in revenue from maintenance services provided to third parties, a decrease in interest expense due to a decrease in outstanding debt from September 30, 2024 to September 30, 2025, and a decrease in depreciation and amortization expense primarily as a result of extending the estimated useful lives on our CRJ700/CRJ550 fleet during the fourth quarter of 2024. These increases in segment profit were partially offset by an increase in our credit loss reserve as a result of our assessment of the credit risk of the outstanding receivables and an increase in aircraft maintenance, materials and repairs due to incremental maintenance services provided to third parties.

**Liquidity and Capital Resources**

As of September 30, 2025, we had $753.4 million in cash and cash equivalents and marketable securities. As of September 30, 2025, we had $75.5 million available for borrowings under our line of credit. Given our available liquidity as of September 30, 2025, 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 $801.6 million as of December 31, 2024 to $753.4 million as of September 30, 2025, or by $48.2 million. At September 30, 2025, our total capital mix (measured as a ratio of total stockholder equity and total long-term debt, including current maturities) was 52.9% equity and 47.1% total long-term debt, compared to 47.4% equity and 52.6% total long-term debt at December 31, 2024. During the nine months ended September 30, 2025, we repurchased 580,257 shares of our common stock for $57.6 million under a share repurchase program authorized by our Board of Directors.

As of September 30, 2025, and December 31, 2024, we had $47.3 million and $47.1 million, respectively, in letters of credit and surety bonds outstanding with various banks and surety institutions. We had no restricted cash as of September 30, 2025, and December 31, 2024.

***Sources and Uses of Cash***

***Cash Flows provided by Operating Activities***

Our cash flows provided by operating activities was $708.9 million for the nine months ended September 30, 2025, compared to $506.6 million for the nine months ended September 30, 2024. 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, asset impairment charges, 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, accrued liabilities, deferred revenue and unbilled revenue.

The increase in our cash flow from operations for the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024, was primarily due to an increase in income before income taxes for the nine months ended September 30, 2025, compared the nine months ended September 30, 2024, and an increase in accounts payable and other liabilities 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 $519.2 million for the nine months ended September 30, 2025, compared to cash flows used in investing activities of $119.0 million for the nine months ended September 30, 2024. 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 $147.6 million for the nine months ended September 30, 2024, to $384.8 million for the nine months ended September 30, 2025. The increase in cash used in investing activities, excluding the transfer of dollars between our investments in marketable securities and our cash accounts, was primarily due to an increase of $216.4 million used in the acquisition of property and equipment and an increase of $31.1 million used for aircraft deposits for the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

***Cash Flows used in Financing Activities***

Our cash flows used in financing activities was $372.5 million for the nine months ended September 30, 2025, compared to cash used in financing activities of $358.2 million for the nine months ended September 30, 2024. Our financing cash flows are typically impacted by various factors including proceeds from issuance of debt, principal payments on debt obligations, repurchases of our common stock and payment of cash dividends.

The $14.3 million decrease in cash used in financing activities for the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024, was primarily due an increase of $20.3 million in cash used for employee income taxes paid on vested equity awards in lieu of shares and an increase of $19.1 million in cash used to purchase treasury stock, offset by an increase of $24.0 million in proceeds from the issuance of long-term debt for the

[**Table of Contents**](#Toc)

purchase of two new E175 aircraft during the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

**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 September 30, 2025, we had a firm purchase commitment for 74 new E175 aircraft from Embraer with delivery dates anticipated into 2032. We also had a firm purchase commitment to purchase 12 used CRJ900 airframes with anticipated delivery dates in 2025.

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 74 E175 aircraft with approximately 75-85% debt and the remaining balance with cash. We intend to use cash to purchase the 12 used CRJ900 airframes.

*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 four years to five years as of September 30, 2025. These eight leased aircraft are subleased to a third party. Future minimum lease payments due under all long-term operating leases were approximately $123.0 million at September 30, 2025. 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 $84.8 million at September 30, 2025.

*Long-term Debt Obligations*

As of September 30, 2025, 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 4.3% at September 30, 2025.

Under our capacity purchase agreements, our major airline partners compensate us for our costs of the aircraft on a monthly basis. The aircraft compensation structure varies by agreement, but is intended to cover either our aircraft principal and interest debt service costs, our aircraft depreciation and interest expense or our aircraft lease expense costs 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.

We have guaranteed $13.0 million in promissory notes of a third party in the event the third party defaults on their payments. The third party's loans are secured by aircraft and engines.

[**Table of Contents**](#Toc)

**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**

**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 nine months ended September 30, 2025, approximately 15.2% of our total flying agreements revenue was derived from prorate agreements and SWC. For the nine months ended September 30, 2025, the average price per gallon of aircraft fuel was $2.98. 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 $21.5 million in fuel expense for the nine months ended September 30, 2025.

**Interest Rates**

As of September 30, 2025, our long-term debt secured by aircraft and spare engines had fixed interest rates. We currently intend to finance the acquisition of aircraft through long-term debt. Changes in interest rates may impact our actual cost to acquire future aircraft. To the extent we place new aircraft in service under our capacity purchase agreements with United, Delta, American, Alaska or other carriers, our capacity purchase agreements currently provide that reimbursement rates will be adjusted to reflect the interest rates effective at the closing of the respective aircraft financing. As such, a hypothetical 50 basis point change in market interest rates would not have a material effect on our financial results. At September 30, 2025, of the $200.6 million unsecured debt payable to Treasury, $95.4 million had a fixed interest rate of 1.0% and the remaining $105.2 million had a variable interest rate of the applicable Secured Overnight Financing Rate ("SOFR") plus 2.00%. The interest rate under the $95.4 million unsecured loans is scheduled to increase to the applicable SOFR rate plus 2.0% upon the fifth anniversary of each disbursement. We received disbursements under these unsecured loans from January 2021 through April 2021. We use the effective interest rate method to record interest expense assuming the unsecured loans are outstanding for the full 10-year term.

**Labor and Inflation Risk**

The global economy has experienced, and continues to experience high rates of inflation. We cannot predict how long these inflationary pressures will continue, or how they may change over time, but we expect to see continued impacts on the global economy and our Company.

As a result, our costs have become, and we expect they will continue to be, subject to inflationary pressures, and we may not be able to fully offset such higher costs through price increases under our capacity purchase agreements. Salaries, wages and benefits expense represented 45.5% of our total operating expense for the nine months ended September 30, 2025. For illustrative purposes, a hypothetical increase of 25% to our salaries, wages and benefits during the nine months ended September 30, 2025, would have increased our operating expenses by approximately $289.8 million.

Our inability or failure to offset a material increase in costs due to inflation and/or labor costs could harm our business, financial condition and operating results. Additionally, in the event we are unable to hire and retain qualified pilots or other operational personnel, including flight attendants and maintenance technicians, we may be unable to operate requested flight schedules under our capacity purchase agreements, which could result in a reduction in revenue

[**Table of Contents**](#Toc)

and operating inefficiencies, such as incremental new-hire training costs, and could harm our business, financial condition and operating results.

**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 September 30, 2025, 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.

**Changes in Internal Control**

During the nine months ended September 30, 2025, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f) under the Exchange Act).

**PART II. OTHER INFORMATION**

**ITEM 1. LEGAL PROCEEDINGS**

We are subject to certain legal actions which we consider routine to our business activities. As of September 30, 2025, our management believed, after consultation with legal counsel, that the ultimate outcome of such legal matters was not likely to have a material adverse effect on our financial position, liquidity or results of operations.

**ITEM 1A. RISK FACTORS**

In addition to the other information set forth in this Report, you should carefully consider the factors discussed in Part I, Item 1A, "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2024, and in our other filings with the SEC, which factors could materially affect our business, financial condition and results of operations. The risks described in our reports filed with the SEC are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and results of operations.

**ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS**

Our Board of Directors (the "Board") has adopted stock repurchase programs which authorize us to repurchase shares of our common stock in the public market or in private transactions, from time to time, at prevailing prices. Our stock repurchase program adopted in May 2023 authorized the repurchase of up to $250.0 million of our common stock. In May 2025, the Board approved a $250 million increase to the existing stock repurchase program. The following table summarizes the repurchases under our stock repurchase program during the three months ended September 30, 2025:

&nbsp;&nbsp;&nbsp;&nbsp;(1) In May 2023, our Board approved a stock repurchase program and authorized us to repurchase up to $250.0 million of our common stock. In May 2025, the Board approved a $250 million increase to the existing stock repurchase program. Purchases are made at management's discretion based on market conditions and financial resources. As of September 30, 2025, we had repurchased 5,407,557 shares of our common stock for $260.0 million and had $240.0 million remaining availability under the stock repurchase program.

**ITEM 5. OTHER INFORMATION**
