### Overview

We have the largest regional airline operation in the United States through our operating subsidiary SkyWest Airlines, Inc. (“SkyWest Airlines”). As of June 30, 2025, we offered scheduled passenger and air freight service with approximately 2,530 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 June 30, 2025, we had 632 total aircraft in our fleet, including 502 aircraft in scheduled service or under contract pursuant to our code-share agreements, summarized as follows:

| ​ ​ | ​ | ​ E175 | ​ | ​ CRJ900 | ​ | ​ CRJ700/CRJ550 | ​ | ​ CRJ200 | ​ | ​ Total |
| --- | --- | ---: | --- | ---: | --- | ---: | --- | ---: | --- | ---: |
| United |  | 116 | ​ | — | ​ | 33 | ​ | 80 | ​ | 229 |
| Delta | ​ | 87 | ​ | 35 | ​ | 20 | ​ | — | ​ | 142 |
| American |  | 20 | ​ | 1 | ​ | 68 | ​ | — | ​ | 89 |
| Alaska |  | 42 | ​ | — | ​ | — | ​ | — | ​ | 42 |
| Aircraft in scheduled service or under contract | ​ | 265 | ​ | 36 | ​ | 121 | ​ | 80 | ​ | 502 |
| SWC | ​ | — | ​ | — | ​ | — | ​ | 8 | ​ | 8 |
| Leased to third parties |  | — | ​ | 5 | ​ | 35 | ​ | — | ​ | 40 |
| Other (1) |  | — | ​ | 12 | ​ | 20 | ​ | 50 | ​ | 82 |
| Total Fleet |  | 265 | ​ | 53 | ​ | 176 | ​ | 138 | ​ | 632 |

(1) As of June 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 June 30, 2024, to June 30, 2025, we made changes to our fleet, including the addition of seven new E175 aircraft and 10 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 from 2025 to 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 2025. We also have multiple agreements with United to place 32 used CRJ550 aircraft into service throughout 2025 and 2026. Timing of placing these additional aircraft into service, including delivery timing on acquired aircraft, may be subject to change as we are coordinating with our major airline partners in response to labor availability or other factors. Our primary objective in the fleet changes is to improve our profitability by adding new E175 aircraft and used CRJ700, CRJ550, CRJ900 and E175 aircraft, commonly referred to as “dual-class CRJ aircraft” to capacity purchase agreements or prorate agreements, and potentially removing older aircraft from service that typically require higher maintenance costs.

As of June 30, 2025, approximately 45.6% of our aircraft in scheduled service or under contract were operated for United, approximately 28.3% were operated for Delta, approximately 17.7% 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 six months ended June 30, 2025, our capacity purchase revenue represented approximately 85.5% of our total flying agreements revenue and our prorate and SWC revenue, combined, represented approximately 14.5% 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.

### Second Quarter Summary

We had total operating revenues of $1.0 billion for the three months ended June 30, 2025, a 19.4% increase compared to total operating revenues of $867.1 million for the three months ended June 30, 2024. We had net income of $120.3 million, or $2.91 per diluted share, for the three months ended June 30, 2025, compared to net income of $75.6 million, or $1.82 per diluted share, for the three months ended June 30, 2024. The significant items affecting our revenue and operating expenses during the three months ended June 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 475 as of June 30, 2024 to 502 as of June 30, 2025, or by 5.7%; and the number of block hours increased from 317,462 for the three months ended June 30, 2024 to 376,269 for the three months ended June 30, 2025, or by 18.5%, 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 $111.0 million, or 15.2%, for the three months ended June 30, 2025, as compared to the three months ended June 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 $38.4 million, or 35.8%, for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024.

#### Operating Expenses

Our total operating expenses increased $117.6 million, or 15.7%, for the three months ended June 30, 2025, compared to the three months ended June 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 three months ended June 30, 2025, compared to the three months ended June 30, 2024. Departures increased from 189,325 for the three months ended June 30, 2024 to 222,874 for the three months ended June 30, 2025, or by 17.7%, and our total block hours increased 18.5% for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. Additional details regarding the increase in our operating expenses are described in the section of this Report entitled “Results of Operations.”

#### Fleet Activity

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

| ​ ​ Aircraft in Service or Under Contract | ​ ​ June 30, 2025 | ​ ​ December 31, 2024 | ​ June 30, 2024 |
| --- | ---: | ---: | ---: |
| E175s | 265 | 262 | 248 |
| CRJ900s | 36 | 36 | 41 |
| CRJ700s/CRJ550s | 121 | 119 | 99 |
| CRJ200s | 80 | 75 | 87 |
| Total | 502 | 492 | 475 |

### 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 six months ended June 30, 2025.

### Recent Accounting Pronouncements

See Note 1 to the condensed consolidated financial statements for a description of recent accounting pronouncements.

### Results of Operations

### Three Months Ended June 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 June 30, 2025, compared to the three months ended June 30, 2024, was primarily due to additional aircraft operating under our capacity purchase agreements and an increase in the number of available captains during the three months ended June 30, 2025, compared to the three months ended June 30, 2024, which allowed for a higher scheduled utilization of our aircraft.

| ​ ​ Block hours by aircraft type: | ​ ​ | ​ ​ For the three months ended June 30, 2025 | ​ ​ 2024 | ​ ​ % Change |
| --- | --- | ---: | ---: | ---: |
| E175s |  | 219,566 ​ | 195,207 ​ | 12.5% |
| CRJ900s | ​ | 22,671 ​ | 20,823 ​ | 8.9% |

#### Operating Revenues

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

| ​ ​ ​ | ​ ​ | ​ ​ For the three months ended June 30, 2025 | ​ | ​ ​ 2024 | ​ | ​ ​ $ Change | ​ | ​ ​ % Change |
| --- | --- | ---: | --- | ---: | --- | ---: | --- | ---: |
| Flying agreements | ​ | $987,511 | ​ | $838,170 | ​ | $149,341 | ​ | 17.8% |
| Lease, airport services and other | ​ | 47,716 | ​ | 28,948 | ​ | 18,768 | ​ | 64.8% |
| Total operating revenues | ​ | $1,035,227 | ​ | $867,118 | ​ | $168,109 |  | 19.4% |

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):

| ​ ​ ​ | ​ ​ | ​ ​ For the three months ended June 30, 2025 | ​ | ​ ​ 2024 | ​ | ​ ​ $ Change | ​ | ​ ​ % Change |
| --- | --- | ---: | --- | ---: | --- | ---: | --- | ---: |
| Capacity purchase agreements flight operations revenue |  | $682,948 |  | $595,127 |  | $87,821 |  | 14.8% |
| Capacity purchase agreements aircraft lease revenue | ​ | ​ 159,118 | ​ | ​ 135,972 | ​ | ​ 23,146 | ​ | 17.0% |
| Prorate agreements and SWC revenue | ​ | 145,445 | ​ | 107,071 | ​ | 38,374 |  | 35.8% |
| Flying agreements revenue |  | $987,511 |  | $838,170 |  | $149,341 |  | 17.8% |

The increase in “Capacity purchase agreements flight operations revenue” of $87.8 million, or 14.8%, was primarily due to an 18.5% increase in block hour production 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 three months ended June 30, 2025, compared to the three months ended June 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 June 30, 2025, we recognized $17.4 million of previously deferred revenue, net of unbilled revenue, related to the non-lease fixed monthly payments we received associated with our flight operations revenues. For the three months ended June 30, 2024, we recognized $5.0 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 $23.1 million, or 17.0%, was primarily due to the addition of aircraft under our capacity purchase agreements from June 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 $5.6 million of previously deferred lease revenue, net of unbilled revenue, during the three months ended June 30, 2025, using the straight-line basis for fixed monthly lease payments, compared to recognizing $0.5 million of previously deferred revenue during the three months ended June 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 $23.0 million of previously deferred revenue, net of unbilled revenue, during the three months ended June 30, 2025, compared to recognizing $5.5 million of deferred revenue, net of unbilled revenue, during the three months ended June 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 $286.5 million as of June 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 $38.4 million, or 35.8%, 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 June 30, 2025, compared to the three months ended June 30, 2024, primarily driven by an increase in available captains.

The increase in lease, airport services and other revenues of $18.8 million, or 64.8%, for the three months ended June 30, 2025, compared to the three months ended June 30, 2024, was primarily due to an increase in revenue from maintenance services provided to third parties.

| Other operating expenses | ​ | 91,246 | ​ | 73,529 | ​ | 17,717 |  | 24.1% |
| Total operating expenses | ​ | $865,099 | ​ | $747,478 | ​ | $117,621 |  | 15.7% |

*Salaries, wages and benefits.* The $35.2 million, or 9.9%, 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 during the three months ended June 30, 2025, compared to the three months ended June 30, 2024.

*Aircraft maintenance, materials and repairs.* The $55.6 million, or 30.3%, increase in aircraft maintenance expense was primarily due to incremental maintenance costs incurred on our CRJ fleet and an increase in our flight volume, which increased our maintenance activity and related expenses, including maintenance services provided to third parties, for the three months ended June 30, 2025, compared to the three months ended June 30, 2024.

*Depreciation and amortization.* The $6.7 million, or 6.9%, 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 seven new E175 aircraft and spare engines since June 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. 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. The $9.6 million, or 54.6%, increase in airport-related expenses for the three months ended June 30, 2025, compared to the three months ended June 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.

*Aircraft fuel.* The $6.1 million, or 28.7%, 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 $3.32 for the three months ended June 30, 2024 to $2.88 for the three months ended June 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:

*(in thousands)*

| ​ ​ | ​ ​ | ​ ​ For the three months ended June 30, 2025 | ​ | ​ ​ 2024 | ​ | ​ ​ % Change |
| --- | --- | ---: | --- | ---: | --- | ---: |
| Fuel gallons purchased | ​ | ​ 9,527 | ​ | ​ 6,415 | ​ | 48.5% |
| Fuel expense | ​ | $27,459 | ​ | $21,328 |  | 28.7% |

*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 $17.7 million, or 24.1%, 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 as of June 30, 2025 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 three months ended June 30, 2025, compared to the three months ended June 30, 2024.

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

*Interest Expense.* Interest expense decreased $2.4 million, or 8.3%, for the three months ended June 30, 2025 as compared to the three months ended June 30, 2024. The decrease in interest expense was primarily related to a decrease in outstanding debt. At June 30, 2025 we had $2.5 billion of outstanding debt, compared to $2.8 billion at June 30, 2024. Our average effective interest rate for the three months ended June 30, 2025 and 2024, was 4.3% and 4.1%, respectively.

*Interest income.* Interest income decreased $0.9 million, from $12.0 million for the three months ended June 30, 2024, to $11.1 million for the three months ended June 30, 2025. The decrease in interest income was primarily related to a decrease in our marketable securities balance from $692.5 million at June 30, 2024, to $678.7 million at June 30, 2025.

*Other income (expense), net.* Other income, net of expenses increased $9.1 million during the three months ended June 30, 2025, compared to the three months ended June 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 and gains on the sale of assets for the three months ended June 30, 2025, compared to the three months ended June 30, 2024.

*Provision for income taxes.* For the three months ended June 30, 2025 and 2024, our effective income tax rates were 26.3% and 26.0%, 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 effective tax rate for the comparable periods did not significantly change.

*Net income.* Primarily due to the factors described above, we generated net income of $120.3 million, or $2.91 per diluted share, for the three months ended June 30, 2025, compared to net income of $75.6 million, or $1.82 per diluted share, for the three months ended June 30, 2024.

### Six Months Ended June 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 six months ended June 30, 2025, compared to the six months ended June 30, 2024, was primarily due to additional aircraft operating under our capacity purchase agreements and an increase in the number of available captains during the six months ended June 30, 2025, compared to the six months ended June 30, 2024, which allowed for a higher scheduled utilization of our aircraft.

| ​ ​ Block hours by aircraft type: | ​ ​ | ​ ​ For the six months ended June 30, 2025 | ​ ​ 2024 | ​ ​ % Change |
| --- | --- | ---: | ---: | ---: |
| E175s |  | 426,928 ​ | 374,192 ​ | 14.1% |
| CRJ900s | ​ | 45,659 ​ | 38,215 ​ | 19.5% |

| Passenger load factor |  | 80.8% | 82.7% | (1.9) pts |
| Average passenger trip length (miles) |  | 457 ​ | 461 ​ | (0.9)% |

#### Operating Revenues

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

| ​ ​ ​ | ​ ​ | ​ ​ For the six months ended June 30, 2025 | ​ | ​ ​ 2024 | ​ | ​ ​ $ Change | ​ | ​ ​ % Change |
| --- | --- | ---: | --- | ---: | --- | ---: | --- | ---: |
| Flying agreements | ​ | $1,903,505 | ​ | $1,616,459 | ​ | $287,046 | ​ | 17.8% |
| Lease, airport services and other | ​ | 80,177 | ​ | 54,273 | ​ | 25,904 | ​ | 47.7% |
| Total operating revenues | ​ | $1,983,682 | ​ | $1,670,732 | ​ | $312,950 |  | 18.7% |

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 six months ended June 30, 2025 | ​ ​ | ​ ​ 2024 | ​ ​ | ​ ​ $ Change | ​ ​ ​ ​ % Change |
| --- | --- | ---: | --- | ---: | --- | ---: | ---: |
| Capacity purchase agreements flight operations revenue |  | $1,322,101 |  | $1,139,287 |  | $182,814 | 16.0% |
| Capacity purchase agreements aircraft lease revenue | ​ | 305,145 | ​ | 269,017 | ​ | 36,128 | 13.4% |
| Prorate agreements and SWC revenue | ​ | 276,259 | ​ | ​ 208,155 | ​ | ​ 68,104 | 32.7% |
| Flying agreements revenue | ​ | $1,903,505 | ​ | $1,616,459 | ​ | $287,046 | 17.8% |

The increase in “Capacity purchase agreements flight operations revenue” of $182.8 million, or 16.0%, was primarily due to a 20.0% increase in block hour production 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 six months ended June 30, 2025, compared to the six months ended June 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 six months ended June 30, 2025, we recognized $27.0 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 six months ended June 30, 2024, we recognized $5.4 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 $36.1 million, or 13.4%, was primarily due to the addition of aircraft under our capacity purchase agreements from June 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 six months ended June 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 $8.9 million of previously deferred lease revenue, net of unbilled revenue, during the six months ended June 30, 2025, using the straight-line basis for fixed monthly lease payments, compared to recognizing $1.0 million of previously deferred revenue during the six months ended June 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 $35.9 million of previously deferred revenue, net of unbilled revenue, during the six months ended June 30, 2025, compared to recognizing $6.4 million of deferred revenue, net of unbilled revenue, during the six months ended June 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 $286.5 million as of June 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 $68.1 million, or 32.7%, was primarily due to an increase in prorate passengers and passenger revenue we received on routes we operated under our prorate agreements driven by an increase in available captains during the six months ended June 30, 2025, compared to the six months ended June 30, 2024. Additionally, a portion of the increase was attributed to an increase in SWC revenue during the six months ended June 30, 2025, compared to the six months ended June 30, 2024.

The increase in lease, airport services and other revenues of $25.9 million, or 47.7%, was primarily due to an increase in maintenance services provided to third parties and an increase in the number of leased assets and lease rates for leases to third parties during the six months ended June 30, 2025, compared to the six months ended June 30, 2024.

#### Operating Expenses

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

| ​ ​ ​ | ​ ​ ​ | ​ ​ For the six months ended June 30, 2025 | ​ ​ | ​ ​ 2024 | ​ ​ | ​ ​ $ Change | ​ ​ | ​ ​ % Change |
| --- | --- | ---: | --- | ---: | --- | ---: | --- | ---: |
| Salaries, wages and benefits | ​ | $767,554 | ​ | $706,004 | ​ | $61,550 | ​ | 8.7% |

| Airport-related expenses | ​ | 54,939 | ​ | 38,423 | ​ | 16,516 |  | 43.0% |
| Aircraft fuel | ​ | 51,947 | ​ | 42,492 | ​ | 9,455 |  | 22.3% |
| Other operating expenses | ​ | 172,156 | ​ | 143,301 | ​ | 28,855 |  | 20.1% |
| Total operating expenses | ​ | $1,674,177 | ​ | $1,451,586 | ​ | $222,591 |  | 15.3% |

*Salaries, wages and benefits.* The $61.6 million, or 8.7%, 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 during the six months ended June 30, 2025, compared to the six months ended June 30, 2024.

*Aircraft maintenance, materials and repairs.* The $119.3 million, or 36.3%, increase in aircraft maintenance expense was primarily due incremental maintenance costs incurred on our CRJ fleet and 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 six months ended June 30, 2025, compared to the six months ended June 30, 2024.

*Depreciation and amortization.* The $13.1 million, or 6.8%, 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 seven new E175 aircraft and spare engines since June 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. 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. The $16.5 million, or 43.0%, increase in airport-related expenses for the six months ended June 30, 2025, compared to the six months ended June 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.

*Aircraft fuel.* The $9.5 million, or 22.3%, 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 $3.42 for the six months ended June 30, 2024 to $2.95 for the six months ended June 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:

*(in thousands)*

| ​ ​ | ​ ​ | ​ ​ For the six months ended June 30, 2025 | ​ | ​ ​ 2024 | ​ | ​ ​ % Change |
| --- | --- | ---: | --- | ---: | --- | ---: |
| Fuel gallons purchased | ​ | ​ 17,600 | ​ | ​ 12,440 | ​ | 41.5% |
| Fuel expense | ​ | $51,947 | ​ | $42,492 |  | 22.3% |

*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 $28.9 million, or 20.1%, 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 six months ended June 30, 2025, compared to the six months ended June 30, 2024.

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

*Interest Expense.* Interest expense decreased $5.1 million, or 8.7%, for the six months ended June 30, 2025 as compared to the six months ended June 30, 2024. The decrease in interest expense was primarily related to a decrease in outstanding debt. At June 30, 2025 we had $2.5 billion of outstanding debt, compared to $2.8 billion at June 30, 2024. Our average effective interest rate for the three and six months ended June 30, 2025 and 2024, was 4.3% and 4.1%, respectively.

*Interest income.* Interest income decreased $2.5 million, from $23.6 million for the six months ended June 30, 2024, to $21.1 million for the six months ended June 30, 2025. The decrease in interest income was primarily related to a decrease in our marketable securities balance from $692.5 million at June 30, 2024, to $678.7 million at June 30, 2025.

*Other income (expense), net.* Other income, net of expenses increased $8.6 million during the six months ended June 30, 2025, compared to the six months ended June 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 six months ended June 30, 2025, compared to the six months ended June 30, 2024.

*Provision for income taxes.* For the six months ended June 30, 2025 and 2024, our effective income tax rates were 22.2% and 25.5%, 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 six months ended June 30, 2025, compared to the six months ended June 30, 2024.

*Net income.* Primarily due to the factors described above, we generated net income of $220.8 million, or $5.32 per diluted share, for the six months ended June 30, 2025, compared to net income of $135.9 million, or $3.28 per diluted share, for the six months ended June 30, 2024.

(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.

(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 three months ended June 30, 2024, consistent with the presentation for the three months ended June 30, 2025.

*SkyWest Leasing Segment Profit.* SkyWest Leasing profit increased $2.7 million, or 3.8%, during the three months ended June 30, 2025, compared to the three months ended June 30, 2024, primarily due to an increase in revenue from maintenance services provided to third parties 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. The increase was offset by incremental maintenance services provided to third parties and an increase in our credit loss reserves on certain outstanding receivables for the three months ended June 30, 2025, compared to the three months ended June 30, 2024.

(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 six months ended June 30, 2024, consistent with the presentation for the six months ended June 30, 2025.

*SkyWest Airlines and SWC Segment Profit.* SkyWest Airlines and SWC segment profit was $144.5 million for the six months ended June 30, 2025, compared to $37.0 million for the six months ended June 30, 2024.

SkyWest Airlines and SWC block hour production increased 20.0%, from 607,263 for the six months ended June 30, 2024 to 728,424 for the six months ended June 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 six months ended June 30, 2025 are set forth below.

SkyWest Airlines and SWC operating revenues increased $312.4 million, or 23.0%, from the six months ended June 30, 2024, to the six months ended June 30, 2025, primarily as a result of an increase in block hour production during the six months ended June 30, 2025, compared to the six months ended June 30, 2024.

SkyWest Airlines and SWC’s salaries, wages and benefits expense increased $61.6 million, or 8.7%, primarily due to an increase in direct labor costs that resulted from the higher number of flights we operated during the six months ended June 30, 2025, compared to the six months ended June 30, 2024.

SkyWest Airlines and SWC’s aircraft maintenance, materials and repairs expense increased $101.4 million, or 32.0%, 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 six months ended June 30, 2025, compared to the six months ended June 30, 2024.

SkyWest Airlines and SWC’s depreciation and amortization expense increased $3.6 million, or 5.0%, primarily due to acquiring additional assets, including engines and CRJ550 aircraft since June 30, 2024.

SkyWest Airlines and SWC’s interest expense decreased $0.6 million, or 8.4%, primarily due to a decrease in outstanding debt from June 30, 2024 to June 30, 2025.

SkyWest Airlines and SWC’s other segment items increased $38.8 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 six months ended June 30, 2025, compared to the six months ended June 30, 2024.

*SkyWest Leasing Segment Profit.* SkyWest Leasing profit decreased $6.1 million, or 4.2%, during the six months ended June 30, 2025, compared to the six months ended June 30, 2024, primarily due to an increase in our credit loss reserve as a result of our assessment of the credit risk of the outstanding receivables, partially offset by a decrease in interest expense due to a decrease in outstanding debt from June 30, 2024 to June 30, 2025. The increase in aircraft maintenance, materials and repairs was due to incremental maintenance services provided to third parties and an increase in our credit loss reserves on certain outstanding receivables, offset by 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.

### Liquidity and Capital Resources

As of June 30, 2025, we had $727.0 million in cash and cash equivalents and marketable securities. As of June 30, 2025, we had $75.0 million available for borrowings under our line of credit. Given our available liquidity as of June 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 $727.0 million as of June 30, 2025, or by $74.6 million. At June 30, 2025, our total capital mix (measured as a ratio of total stockholder equity and total long-term debt, including current maturities) was 50.8% equity and 49.2% total long-term debt, compared to 47.4% equity and 52.6% total long-term debt at December 31, 2024. During the six months ended June 30, 2025, we repurchased 335,843 shares of our common stock for $31.0 million under a share repurchase program authorized by our Board of Directors.

As of June 30, 2025, and December 31, 2024, we had $49.1 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 June 30, 2025, and December 31, 2024.

### Sources and Uses of Cash

***Cash Position and Liquidity.*** The following table provides a summary of the net cash provided by (used in) our operating, investing and financing activities for the six months ended June 30, 2025 and 2024, and our total cash and marketable securities positions as of June 30, 2025, and December 31, 2024 (in thousands):

| ​ ​ ​ | ​ ​ | ​ ​ For the six months ended June 30, 2025 | ​ | ​ ​ 2024 | ​ | ​ ​ $ Change | ​ | ​ ​ % Change |

### Cash Flows provided by Operating Activities

Our cash flows provided by operating activities was $428.1 million for the six months ended June 30, 2025, compared to $323.0 million for the six months ended June 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 six months ended June 30, 2025, compared to the six months ended June 30, 2024, was primarily due to an increase in income before income taxes for the six months ended June 30, 2025, compared the six months ended June 30, 2024, and an increase in certain current liability accounts 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 $372.7 million for the six months ended June 30, 2025, compared to cash flows used in investing activities of $76.0 million for the six months ended June 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 $69.6 million for the six months ended June 30, 2024, to $268.1 million for the six months ended June 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 $184.8 million used in the acquisition of property and equipment and an increase of $31.1 million used for aircraft deposits for the six months ended June 30, 2025, compared to the six months ended June 30, 2024. This was offset by a decrease in our cash used to acquire other long-term assets for the six months ended June 30, 2025.

### Cash Flows used in Financing Activities

Our cash flows used in financing activities was $234.5 million for the six months ended June 30, 2025, compared to cash used in financing activities of $253.5 million for the six months ended June 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 $19.0 million decrease in cash used in financing activities for the six months ended June 30, 2025, compared to the six months ended June 30, 2024, was primarily due an increase of $47.1 million in proceeds from the issuance of long-term debt for the purchase of two new E175 aircraft, offset by 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 $8.8 million in cash used to purchase treasury stock during the six months ended June 30, 2025, compared to the six months ended June 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 June 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 21 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 21 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 June 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 $118.7 million at June 30, 2025. Assuming a 6.3% 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 $79.9 million at June 30, 2025.

#### Long-term Debt Obligations

As of June 30, 2025, we had $2.5 billion of long-term debt, which consisted of $2.3 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 June 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 $13.3 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.

### 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.

## Market risk

As filed, 3,994 characters.

### 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 six months ended June 30, 2025, approximately 14.5% of our total flying agreements revenue was derived from prorate agreements and SWC. For the six months ended June 30, 2025, the average price per gallon of aircraft fuel was $2.95. 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 $13.0 million in fuel expense for the six months ended June 30, 2025.

### Interest Rates

As of June 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 June 30, 2025, of the $200.6 million unsecured debt payable to Treasury, $138.6 million had a fixed interest rate of 1.0% and the remaining $62.0 million had a variable interest rate of the applicable Secured Overnight Financing Rate ("SOFR") plus 2.00%. The interest rate under the $138.6 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 July 2020 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 45.8% of our total operating expense for the six months ended June 30, 2025. For illustrative purposes, a hypothetical increase of 25% to our salaries, wages and benefits during the six months ended June 30, 2025, would have increased our operating expenses by approximately $191.9 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 and operating inefficiencies, such as incremental new-hire training costs, and could harm our business, financial condition and operating results.

## Controls and procedures

As filed, 1,323 characters.

### 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 June 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 six months ended June 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).

## Risk factors

As filed, 658 characters.

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.
