Insights

Airline equity analyst

Quarter shows cargo-driven growth, passenger softness, steady liquidity.

Sun Country delivered modest top-line growth in Q3 on a larger cargo footprint. Cargo revenue rose to $44.0M (up 51%) as eight additional Amazon aircraft entered service, while passenger revenue fell 3% to $201.1M due to lower capacity. Operating income was $9.9M, reflecting higher labor and maintenance.

Balance sheet metrics remain orderly: cash was $111.8M, debt $304.1M. The new $75.0M revolver was fully available at quarter-end, and a $108.0M term loan (fixed 5.98%) refinanced prior borrowings. Interest expense declined year over year.

Capital returns continued with Q3 repurchases of 843,107 shares for $10.0M, leaving $15.0M authorized. Cargo expansion and charter strength support revenue diversity; actual earnings will hinge on cost trends and passenger capacity decisions disclosed for the period.

(Unaudited)

1.    BASIS OF PRESENTATION

Sun Country Airlines Holdings, Inc. (together with its consolidated subsidiaries, "Sun Country" or the "Company") is the parent company of Sun Country, Inc., which is a certificated air carrier providing scheduled passenger service, air cargo service, charter air transportation and related services.

The Company has prepared the unaudited Condensed Consolidated Financial Statements according to U.S. Generally Accepted Accounting Principles (“GAAP”) and has included the accounts of Sun Country Airlines Holdings, Inc. and its subsidiaries. Certain information and footnote disclosures normally included in the audited annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") for Form 10-Q. Therefore, the accompanying unaudited Condensed Consolidated Financial Statements of Sun Country Airlines Holdings, Inc. should be read in conjunction with the Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2024 as filed with the SEC ("2024 10-K"). These unaudited Condensed Consolidated Financial Statements reflect all normal recurring adjustments that are necessary for the fair presentation of the Company’s financial position, results of operations, and cash flows for the respective periods presented. All material intercompany balances and transactions have been eliminated in consolidation.

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

Due to impacts from seasonal variations in the demand for air travel, the volatility of aircraft fuel prices, the impact of macroeconomic conditions, and other factors, operating results for the nine months ended September 30, 2025 are not necessarily indicative of operating results for other interim periods or for the full year ending December 31, 2025.

Recently Issued Accounting Standards

In December 2023, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU requires, among other disclosures, greater disaggregation of information, the use of certain categories in the rate reconciliation, and the disaggregation of income taxes paid by jurisdiction. The ASU is effective for public business entities for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company intends to adopt this standard retrospectively within its Annual Report on Form 10-K for the year ended December 31, 2025. Upon adoption of this ASU, the Company will include the incremental disclosures in the footnotes to its Consolidated Financial Statements, as required.

2.    REVENUE

Sun Country is a certificated air carrier generating Operating Revenues from Passenger (consisting of Scheduled Service, Charter, and Ancillary), Cargo and Other revenue. Scheduled Service revenue mainly consists of base fares. Charter revenue is primarily generated through service provided to the U.S. Department of Defense ("DoD"), collegiate and professional sports teams, and casinos. Ancillary revenue consists of revenue earned from air travel-related services, such as: baggage fees, seat selection fees, other fees and on-board sales. Cargo consists of revenue earned from flying cargo aircraft for Amazon.com Services, Inc. (together with its affiliates, “Amazon”) under the Amended and Restated Air Transportation Services Agreement (the “A&R ATSA”). Other revenue consists primarily of revenue from services in

connection with Sun Country Vacations products, rental revenue related to certain transactions where the Company serves as a lessor, and revenue for the brand and marketing performance obligation related to the Company's co-branded credit card program. The Company recognized rental revenue of $7,135 and $10,092, during the three months ended September 30, 2025 and 2024, respectively; and $26,751 and $29,240 during the nine months ended September 30, 2025 and 2024, respectively.

In June 2024, the Company entered into the A&R ATSA with Amazon that increased the number of Boeing 737-800 cargo aircraft that Sun Country operates on behalf of Amazon from 12 to 20 in 2025. For more information on the A&R ATSA, see Note 2, "Basis of Presentation and Summary of Significant Accounting Policies" included within Part II, Item 8 of the 2024 10-K. During the nine months ended September 30, 2025, the Company received and placed in-service all eight additional cargo aircraft under the A&R ATSA.

In March 2025, the Company entered into a Credit Card Program Agreement for a new co-branded credit card program ("Credit Card Program"). The Credit Card Program launched in the third quarter of 2025. Upon launch of the program, the Company received a one-time payment of $1,016, which was recorded as a contract liability. The one-time payment will be amortized into Other Revenue on a straight-line basis over the term of the agreement. Subject to certain exceptions, the Credit Card Program has a term of seven years following its launch.

The significant categories comprising Operating Revenues are as follows:

			Three Months Ended September 30,												Nine Months Ended September 30,
			2025						2024						2025						2024
Scheduled Service			$	76,746					$	83,784					$	308,406					$	313,056
Charter			58,673						50,769						167,636						149,090

Total Operating Revenues			$	255,538					$	249,470					$	845,808					$	815,334

The Company attributes and measures its Operating Revenues by geographic region as defined by the U.S. Department of Transportation ("DOT") for airline reporting based upon the origin of each passenger and cargo flight segment.

The Company’s operations are highly concentrated in the U.S., but include service to many international locations, primarily consisting of scheduled service to Latin America and military charter service to various international destinations.

Total Operating Revenues by geographic region are as follows:

			Three Months Ended September 30,												Nine Months Ended September 30,
			2025						2024						2025						2024

Contract Balances

The Company’s contract assets primarily relate to costs incurred to prepare the Amazon cargo aircraft for service under the original ATSA and the A&R ATSA, as well as warrants that have vested and will be amortized against Cargo revenue over the remaining term of the A&R ATSA. The balances are included in Other Current Assets and Other Assets on the Condensed Consolidated Balance Sheets.

The Company’s contract liabilities are primarily comprised of: 1) ticket sales for transportation that have not yet been provided (reported as Air Traffic Liabilities on the Condensed Consolidated Balance Sheets), 2) outstanding loyalty points that may be redeemed for future travel and other non-air travel awards (reported as Loyalty Program Liabilities on the Condensed Consolidated Balance Sheets), 3) the Amazon Deferred Up-front Payment received under the original ATSA (reported within Other Current Liabilities and Other Long-term Liabilities on the Condensed Consolidated Balance Sheets), and 4) a one-time payment received upon launch of the co-branded Credit Card Program (reported within Other Current Liabilities and Other Long-term Liabilities on the Condensed Consolidated Balance Sheets).

Contract Assets and Liabilities are as follows:

			September 30, 2025						December 31, 2024
Contract Assets
Amazon Contract			$	11,752					$	4,135
Total Contract Assets			$	11,752					$	4,135
Contract Liabilities
Air Traffic Liabilities			$	144,430					$	160,686
Loyalty Program Liabilities			14,645						14,601
Amazon Contract			1,773						1,612
Credit Card Program			1,013						—
Total Contract Liabilities			$	161,861					$	176,899

The balance in the Air Traffic Liabilities fluctuates with seasonal travel patterns. Most tickets can be purchased no more than 12 months in advance, therefore any revenue associated with tickets sold for future travel will be recognized within that timeframe. For the nine months ended September 30, 2025, $155,471 of revenue was recognized in Passenger revenue that was included in the Air Traffic Liabilities as of December 31, 2024.

Loyalty Program

The Sun Country Rewards program provides loyalty awards to program members based on accumulated loyalty points. The Company records a liability for loyalty points earned by passengers under the Sun Country Rewards program using two methods: 1) a liability for points that are earned by passengers on purchases of the Company’s services is established by deferring revenue based on the redemption value, net of estimated loyalty points that will expire unused, or breakage; and 2) a liability for points attributed to loyalty points issued to the Company’s co-branded credit card holders is established by deferring a portion of payments received from the Company’s co-branded agreement. The balance of the Loyalty Program Liabilities fluctuates based on seasonal patterns, which impacts the volume of loyalty points awarded through travel or issued to co-branded credit card and other partners (deferral of revenue) and loyalty points

redeemed (recognition of revenue). Due to these reasons, the timing of loyalty point redemptions can vary significantly.

Changes in the Loyalty Program Liabilities are as follows:

			2025						2024
Balance – January 1			$	14,601					$	13,737
Loyalty Points Earned			6,711						6,573
Loyalty Points Redeemed (1) (2)			(6,667)						(6,128)
Balance – September 30			$	14,645					$	14,182

______________________

(1)			Loyalty points are combined in one homogenous pool, which includes both air and non-air travel awards, and are not separately identifiable. As such, the revenue recognized is comprised of points that were part of the Loyalty Program Liabilities balance at the beginning of the period, as well as points that were earned during the period.
(2)			Includes Other Deferred Loyalty payments, net of the amount earned.

been pledged to support the ability to efficiently utilize the Company's four-year $75,000 revolving credit facility (“Revolving Credit Facility”) entered into during March 2025, and one aircraft was unencumbered. See Note 5 for more information on the Company's Revolving Credit Facility.

Upon acquisition of the Owned Aircraft held for Operating Lease in March 2023, the Company recognized a Maintenance Rights Asset associated with the acquired leases. During the three months ended June 30, 2025, the Company accepted delivery one of the Owned Aircraft Held for Operating Lease that was previously leased to an unaffiliated airline. Based on the maintenance condition of the one aircraft returned in 2025, the Maintenance Rights Asset settlement resulted in capitalized asset improvements of $4,697 and cash received from the lessee in excess of the Maintenance Rights Asset totaling $2,716. The cash received for end of lease compensation in excess of the Maintenance Rights Asset was recognized within Other Revenue in the Company’s Condensed Consolidated Statement of Operations during the three months ended June 30, 2025. The aircraft was placed in-service as of September 30, 2025.

During the nine months ended September 30, 2024, the Company acquired one incremental aircraft and took control of two aircraft through finance lease arrangements, one of which was subsequently subleased to an unaffiliated airline. Further, the Company purchased one aircraft previously classified as a finance lease.

5.    DEBT

Credit Facilities

In March 2025, the Company executed a new $75,000 Revolving Credit Facility with a group of lenders. The new Revolving Credit Facility replaces the Company's previous $25,000 revolving credit facility. The interest rate on borrowings is determined using a base rate plus an applicable margin of 2.5%. In addition, there is a commitment fee on the unused Revolving Credit Facility of 0.6%. The Revolving Credit Facility is guaranteed by the Company and secured by a pool of collateral. Accordingly, the Company pledged certain assets as collateral, including certain previously unencumbered aircraft, to support the ability to efficiently utilize the Revolving Credit Facility. Available funds from the Revolving Credit Facility can be used for general corporate purposes. The Revolving Credit Facility includes financial covenants that require the Company to maintain: 1) minimum liquidity, as defined within the agreement, of not less than $55,000, 2) a minimum adjusted EBITDAR of $110,000 for any four consecutive fiscal quarters and 3) a minimum ratio of the borrowing base of the collateral to outstanding obligations under the Revolving Credit Facility of not less than 1.0 to 1.0. The Company was in compliance with these financial covenants as of September 30, 2025. As of September 30, 2025, the Company had $75,000 of financing available through the Revolving Credit Facility.

Long-term Debt

2025 Term Loan Facility

In September 2025, the Company executed a term loan facility with a face amount of $108,000 ("2025 Term Loan Facility") for the purpose of refinancing the Company's five Boeing 737-900ER aircraft, of which three are on lease to an unaffiliated airline. The Company's five Boeing 737-900ERs are pledged as collateral. During the three months ended September 30, 2025, the Company drew $54,000 from the 2025 Term Loan Facility. The proceeds were used to repay the remaining $20,953 of the term loan credit facility executed in March 2023 ("2023 Term Loan Credit Facility") with the remainder to be used for general corporate purposes. The 2025 Term Loan Facility is repaid quarterly through September 2032, with the remaining balance due and payable in a single payment upon maturity.

The fixed interest rate on the 2025 Term Loan Facility is 5.98%, which was determined using a base rate plus an applicable margin of 2.60%. During the three months ended September 30, 2025, the Company recorded $1,059 in debt issuance costs associated with the 2025 Term Loan Facility. As of September 30, 2025, the Company had $54,000 of financing available through the 2025 Term Loan Facility. All remaining financing through the 2025 Term Loan Facility must be drawn by December 19, 2025.

2023 Term Loan Credit Facility

During the three months ended March 31, 2023, the Company executed the 2023 Term Loan Credit Facility with a face amount of $119,200 for the purpose of financing the initial acquisition of five Boeing 737-900ER aircraft. On the acquisition date, all five aircraft were on lease to an unaffiliated airline. The loan was repaid monthly. During the lease term, payments collected from the lessee were applied directly to the repayment of principal and interest on the 2023 Term Loan Credit Facility. The Owned Aircraft Held for Operating Lease, as well as the related lease payments received from the lessee, are pledged as collateral. In December 2024, the Company made a partial repayment of $60,000 on the 2023 Term Loan Credit Facility using proceeds from the reissued Class C trust certificates Series 2019-1.

During the three months ended September 30, 2025, the Company repaid the outstanding balance of $20,953 of the 2023 Term Loan Credit Facility in full using proceeds received from the 2025 Term Loan Facility. The Company recorded a $391 loss on extinguishment of debt during the three months ended September 30, 2025 in connection with repayment of the 2023 Term Loan Credit Facility, which represents the write-off of the remaining unamortized deferred financing costs.

Pass-Through Trust Certificates

During March 2022, the Company arranged for the issuance of Class A and Class B certificates Series 2022-1 (the "2022-1 EETC") in an aggregate face amount of $188,277 for the purpose of financing or refinancing 13 aircraft. The Company is required to make bi-annual principal and interest payments each March and September, through March 2031. These notes bear interest at an annual rate between 4.84% and 5.75%. The weighted average interest rate was 5.04% as of September 30, 2025.

In December 2019, the Company arranged for the issuance of Class A, Class B and Class C trust certificates Series 2019-1 (the “2019-1 EETC”), in an aggregate face amount of $248,587 for the purpose of financing or refinancing 13 aircraft, which was completed in 2020. The Company is required to make bi-annual principal and interest payments each June and December, through December 2027.

In December 2024, the Company reissued Class C trust certificates from the 2019-1 EETC, which had previously been repaid, in an aggregate face amount of $60,000 and concurrently applied the proceeds to

8.    INCOME TAXES

The Company's effective tax rate for the three and nine months ended September 30, 2025 was 28.3% and 24.1%, respectively. The Company's effective tax rate for the three and nine months ended September 30, 2024 was 22.0% and 25.0%, respectively. The effective tax rate represents a blend of federal and state taxes and includes the impact of certain nondeductible or nontaxable items. The effective tax rate in both periods was impacted by permanent stock compensation items.

On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was signed into law. The Company's effective tax rate for 2025 is not expected to materially change as a result of the legislation.

Tax Receivable Agreement

The total Tax Receivable Agreement ("TRA") balance as of September 30, 2025 and December 31, 2024 was $87,169 and $97,694, of which $1,192 and $10,325 was current, respectively. The TRA liability is an estimate and actual amounts payable and/or the timing of TRA payments could differ from this estimate. For example, changes to full year taxable income, as well as changes in tax laws may impact the timing of TRA liability payments. The decrease in the current portion of the TRA balance is primarily due to the OBBBA enacted on July 4, 2025. During the nine months ended September 30, 2025 and 2024, the Company made payments of $10,525 and $3,350, respectively, to the pre-IPO stockholders (the “TRA holders”), which includes certain members of the Company's management and certain members of the Company's Board of Directors. The payment is included within Financing Activities on the Condensed Consolidated Statements of Cash Flows. Payments will be made in future periods as attributes that existed at the time of the IPO (the “Pre-IPO Tax Attributes”) are utilized.

9.    SPECIAL ITEMS, NET

Special Items, net reflects expenses, or credits to expense, that are not representative of our ongoing costs for the periods presented and may vary from period to period in nature, frequency, and amount.

In March 2025, the Company's flight attendants, represented by the International Brotherhood of Teamsters, ratified a new five-year collective bargaining agreement. Upon ratification of the new agreement, eligible flight attendants became entitled to a one-time ratification bonus. Eligibility requirements stipulate that flight attendants must be on the seniority list as of the ratification date, have completed probation, and hold an active status in order to receive the bonus payment. Certain portions of the ratification bonus will be paid in future periods as flight attendants on the seniority list as of the ratification date complete their probationary period or change their status from inactive to active. Ratification bonuses were paid to all eligible flight

The Company recognized ratification bonuses of $26 and $1,874, including $2 and $144 of payroll-related tax expense, for the three and nine months ended September 30, 2025, respectively. These items were included within Special Items, net on the Company's Condensed Consolidated Statements of Operations.

10.    STOCKHOLDERS' EQUITY

Equity Transactions

Common Stock Repurchases

The Company may purchase shares of its Common Stock on a discretionary basis from time-to-time through open market repurchases, privately negotiated transactions, accelerated share repurchase, or other means, including through Rule 10b5-1 trading plans.

During the three months ended March 31, 2025, the Company announced the commencement of a secondary public offering of 6,346,105 shares of its Common Stock by the SCA Horus Stockholder.

The Company received authorization from its Board of Directors to repurchase up to $10,000 of its Common Stock in connection with this offering. The underwriters agreed to sell to the Company, and the Company agreed to purchase up to $10,000 of the Company's Common Stock from the underwriters equal to the price at which the underwriter purchased the shares from the SCA Horus Stockholder. As part of this transaction, the Company repurchased 630,914 shares of its Common Stock, for a total cost of $10,000, or an average price of $15.85 per share. The Company incurred offering expenses of $481 in conjunction with the secondary public offering.

During the three months ended June 30, 2025, the Company's Board of Directors authorized $25,000 to repurchase shares of the Company's Common Stock. During the three months ended September 30, 2025, the Company repurchased 843,107 shares of its Common Stock at a total cost of $10,015, inclusive of commissions paid, or an average price of $11.88 per share. The repurchases were open market purchases. As of September 30, 2025, there was $15,000 remaining of authorization from the Company's Board of Directors to repurchase shares of the Company's Common Stock.

During the nine months ended September 30, 2024, the Company repurchased 755,284 shares of its Common Stock at a total cost of $11,493, inclusive of commissions paid, or an average price of $15.22 per share. The repurchases were open market purchases.

Amazon Agreement

In connection with the ATSA, the Company issued warrants to Amazon to purchase an aggregate of up to 9,482,606 shares of common stock at an exercise price of approximately $15.17 per share. During the nine months ended September 30, 2025 and 2024, 885,042 and 632,173 warrants vested in each respective period. As of September 30, 2025 and 2024, the cumulative vested warrants held by Amazon were 4,994,177 and 3,856,266, respectively. The exercise period for these warrants extends through the eighth anniversary of the issue date.

11.    COMMITMENTS AND CONTINGENCIES

The Company has contractual obligations and commitments primarily with regard to lease arrangements, repayment of debt (see Note 5), payments under the TRA (see Note 8), and probable future purchases of aircraft.

The Company is subject to an audit by the Internal Revenue Service (“IRS”) related to the collection of federal excise taxes on optional passenger seat selection charges covering the period of October 1, 2021 through June 30, 2023. During 2024, the Company received an assessment of approximately $2,700 from the IRS related to the results of the audit. As of September 30, 2025, the Company has appealed the results of the audit through a formal protest with the IRS and there has been no further change in status on this matter. The Company believes a loss in this matter is not probable and has not recognized a loss contingency as of September 30, 2025.

The Company is subject to various legal proceedings in the normal course of business and expenses legal costs as incurred. Management does not believe these proceedings will have a materially adverse effect on the Company.

12.    OPERATING SEGMENTS

The Company has two operating and reportable segments: Passenger and Cargo, which are determined by the services provided and fleet utilized. The Chief Operating Decision Maker ("CODM") makes resource allocation decisions with the objective of generating high returns and margins and mitigating the seasonality of the Company’s route network. Operating Income is the measure of segment profit that is the most consistent with the amounts presented in the Company’s Condensed Consolidated Financial Statements, as well as the measure the CODM uses to assess segment performance. The accounting policies for the Company’s reportable segments are consistent with those described in Note 2, "Basis of Presentation and Summary of Significant Accounting Policies" included within Part II, Item 8 of the 2024 10-K. There are no intercompany transactions between the Company’s reportable segments.

The following tables present financial information for the Company’s two operating segments: Passenger and Cargo. Certain non-fuel operating expenses are allocated between Passenger and Cargo based on metrics such as block hours, fleet count and departures, which best align with the nature of the respective expense. Other Operating, net includes crew and other employee travel, interrupted trip expenses, information technology, property taxes and insurance, including hull-liability insurance, supplies, legal and other professional fees, facilities and all other administrative and operational overhead expenses. The CODM does not consider Interest Income, Interest Expense, and Other Income, net, in assessing the financial performance of its operating segments. Collectively, these items are included in reconciling reporting segment financial amounts to the consolidated financial amounts.

Nearly all of the Company’s long-lived assets are associated with the Passenger operating segment. Therefore, predominately all depreciation and amortization expense is associated with the Passenger operating segment. Substantially all the Company’s tangible assets are located in the U.S. The Company's Aircraft and Flight equipment are mobile across geographic markets. As a result, assets by segment are not reviewed by the CODM and have not been presented herein.

Unless otherwise indicated, the terms “Sun Country,” “we,” “us” and “our” refer to Sun Country Airlines Holdings, Inc., and its subsidiaries.

Forward-Looking Statements

The following discussion and analysis presents factors that had a material effect on our results of operations during the nine months ended September 30, 2025 and 2024. Also discussed is our financial position as of September 30, 2025 and December 31, 2024. This section should be read in conjunction with our unaudited Condensed Consolidated Financial Statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q and our audited Consolidated Financial Statements and related notes and discussion under the heading, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2024 10-K. This discussion contains forward-looking statements that involve risk, assumptions and uncertainties, such as statements of our plans, objectives, expectations, intentions and forecasts. Our actual results and the timing of selected events could differ materially from those discussed in these forward-looking statements as a result of several factors, including those set forth under the section of this report titled, “Risk Factors” and elsewhere in this report. You should carefully read the “Risk Factors” included in our 2024 10-K to gain an understanding of the important factors that could cause actual results to differ materially from our forward-looking statements.

Business Overview

Sun Country is a new breed of hybrid low-cost air carrier that dynamically and synergistically deploys shared resources across our Passenger and Cargo segments, and within our Passenger segment, across our Scheduled Service and Charter Service businesses. By doing so, we believe we are able to generate high growth, high margins and strong cash flows with greater resilience than other passenger airlines. Based in Minnesota, we focus on serving leisure and visiting friends and relatives ("VFR") passengers, Charter customers and providing crew, maintenance and insurance (“CMI”) service to Amazon, with flights throughout the U.S. and to destinations in Canada, Mexico, Central America and the Caribbean. We share resources, such as flight crews, across our Scheduled Service, Charter and Cargo business lines with the objective of generating high returns and margins and mitigating the seasonality of our route network. We optimize capacity using an agile peak demand scheduling strategy which aims to shift flying to markets during periods of peak demand and away from markets during periods of low demand. We believe this flexible business model provides greater resiliency to economic and industry downturns than a traditional scheduled service carrier. This strategy has been implemented and executed by an experienced management team with deep knowledge of the industry.

In March 2025, we entered into a Credit Card Program Agreement for a new co-branded credit card program ("Credit Card Program"). The Credit Card Program launched in the third quarter of 2025. Subject to certain exceptions, the Credit Card Program has a term of seven years following its launch.

For more information on our business and strategic advantages, see the "Business" and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections within Part I, Item 1 and Part II, Item 7, respectively, in our 2024 10-K.

Operations in Review

We believe a key component of our success is establishing Sun Country as a high growth, low-cost carrier in the U.S. by attracting customers with low fares and garnering repeat business by delivering a high-quality

passenger experience, offering state-of-the-art interiors, complimentary streaming of in-flight entertainment to passenger devices, seat reclining and seat-back power in all our aircraft.

The demand for air travel services has historically been affected by U.S. and global economic conditions, or other geopolitical events. Our diversified business model, which includes a focus on leisure and VFR passengers, Charter and Cargo service, all primarily within the U.S., is unique in the airline sector and helps mitigate the impact of cyclical, economic, and industry downturns on our business when compared with other large U.S. passenger airlines. For example, most of our Charter contracts are non-cyclical because these customers still fly during normal economic downturns, and our casino contracts are long-term in nature. Further, our crew can be utilized by flying Cargo service in periods when the Passenger business is less profitable. Our business model is flexible, which gives us the ability to adjust our services in response to market conditions and is intended to produce the highest possible returns for Sun Country.

Certain accounting estimates and assumptions used in the preparation of our Condensed Consolidated Financial Statements involve financial projections or depend on factors that are inherently uncertain and challenging to estimate during periods of economic uncertainty. Should the current economic uncertainty persist or worsen, the Company may need to reevaluate these estimates and assumptions, potentially resulting in a material impact on the Company's financial position, assets, or earnings.

In June 2024, the Company entered into the A&R ATSA with Amazon that increased the number of Boeing 737-800 cargo aircraft that we operate on behalf of Amazon from 12 to 20 in 2025. During the nine months ended September 30, 2025, the Company received and placed in-service all eight additional cargo aircraft under the A&R ATSA. In the near term, the increase in aircraft we operate on behalf of Amazon will result in more resources being allocated to the Cargo business. This aligns with our strategy of long-term flexibility and supports our ability to mitigate the impact of cyclical, economic, and industry downturns on our business.

Total Operating Revenues increased $6,068, or 2%, to $255,538 for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. The increase was primarily the result of growth in Cargo revenue due to additional aircraft received and operated, as well as contractual rate increases under the A&R ATSA. This increase was partially offset by a decrease in Passenger revenue due to reduced capacity as we focused our operations on growth within the Cargo business. These items are discussed in further detail below.

Passenger. Passenger revenue decreased $6,666, or 3%, to $201,098 for the three months ended September 30, 2025 as compared to the three months ended September 30, 2024. The table below presents select operating data for lines of revenue within Passenger, expressed as quarter-over-quarter changes:

(1) Percentage point difference

Our quarter-over-quarter results were impacted by reduced passenger capacity as we focused our operations on growth in the Cargo business. This resulted in a 12% decrease in Scheduled Service departures and a 10% decrease in ASMs, which were partially offset by a 2% increase in TRASM and a 1% increase in total fare per passenger. Total Ancillary revenues declined quarter-over-quarter due to the 10% decrease in passengers. Ancillary revenue per passenger quarter-over-quarter was materially consistent.

Passenger revenue benefited from the $7,904, or 16%, increase in Charter revenue during the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. This increase was the result of an 11% increase in block hours and a 4% increase in Charter revenue per block hour. The quarter-over-quarter increase in block hours was due to an increase in flying by large program customers and ad hoc flying. The increase in Charter revenue per block hour was primarily driven by rate increases, partially offset by lower fuel recovery revenue due to the quarter-over-quarter decrease in fuel cost per gallon.

Cargo. Revenue from cargo services increased $14,858, or 51%, to $44,023 for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. The increase was primarily due to additional aircraft and contractual rate increases. During the nine months ended September 30, 2025, the Company received and placed in-service all eight additional cargo aircraft under the A&R ATSA.

Other. Other revenue decreased $2,124, or 17%, to $10,417 for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. The decrease was driven by lower aircraft lease revenue. For the three months ended September 30, 2025 and 2024, there were an average of 5 and 7 aircraft on lease to unaffiliated airlines, respectively. For more information, see Note 4 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Operating Expenses

Aircraft Fuel. We believe Aircraft Fuel expense, excluding indirect fuel credits, is the best measure of the effect of fuel prices on our business as it consists solely of direct fuel expenses that are related to our operations and is consistent with how management analyzes our operating performance. This measure is defined as GAAP Aircraft Fuel expense, excluding indirect fuel expenses and credits that are recognized within Aircraft Fuel expense, but are not directly related to our Fuel Cost per Gallon.

The primary components of Aircraft Fuel expense are shown in the following table:

			Three Months Ended September 30,												% Change
			2025						2024
Total Aircraft Fuel Expense			$	48,583					$	54,737					(11)		%
Indirect Fuel (Expenses) Credits			(6)						68						(109)		%
Aircraft Fuel Expense, Excluding Indirect Fuel (Expenses) Credits			$	48,577					$	54,805					(11)		%
Fuel Gallons Consumed (thousands)			19,049						20,344						(6)		%
Fuel Cost per Gallon, Excluding Indirect Fuel (Expenses) Credits			$	2.55					$	2.69					(5)		%

Aircraft Fuel expense decreased 11% quarter-over-quarter due to a 5% decrease in the average fuel cost per gallon and a 6% decrease in fuel consumption due to reduced passenger capacity as we focused our operations on growth in the Cargo business.

Salaries, Wages, and Benefits. Salaries, Wages, and Benefits expense increased $12,174, or 15%, to $93,093 for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. The quarter-over-quarter increase in Salaries, Wages, and Benefits was impacted by an 11% increase in employee headcount to support our expanding operations, contractual rate increases for our pilots, and contractual pay increases as a result of new collective bargaining agreements.

Maintenance. Maintenance expense increased $2,150, or 13%, to $18,123 for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. The quarter-over-quarter increase in Maintenance expense was primarily driven by growth in our fleet and operations, higher rates for service, and an increase in engine maintenance events. These increases were partially offset by a quarter-over-quarter decrease in the number of routine, time-based airframe heavy maintenance events.

Sales and Marketing. Sales and Marketing expense decreased $766, or 10%, to $6,982 for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. The quarter-over-quarter decrease was primarily driven by lower booking and credit card transaction fees due to the shift in capacity growth from Scheduled Service to the Cargo business.

Depreciation and Amortization. Depreciation and Amortization expense increased $929, or 4%, to $24,683 for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. The increase was primarily driven by a non-cash expense of $737 due to an unplanned engine retirement as well as an increase in certain capitalized costs associated with two aircraft being returned off of leases.

Ground Handling. Ground Handling expense decreased $101, or 1% for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. The decrease was primarily driven by

(Dollars in thousands, except per share amounts)

(Unaudited)

the 7% decrease in Passenger segment departures as we focused our operations on the growth in Cargo, partially offset by Charter customer mix.

Landing Fees and Airport Rent. Landing Fees and Airport Rent increased $832, or 5%, to $16,811 for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. This quarter-over-quarter increase was driven by rate increases at airports due to market pressures, primarily at Minneapolis – St. Paul International Airport ("MSP"), partially offset by a 7% decrease in Passenger segment departures.

Special Items, net. Special Items, net consisted of $26 of ratification bonuses for the new five-year collective bargaining agreement paid to eligible flight attendants during the period, as well as the related payroll tax expense. For more information, see Note 9 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Other Operating, net. Other Operating, net decreased $542, or 2%, to $25,868 for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. The decrease was primarily the result of increased quarter-over-quarter activity from our engine parts sales programs, partially offset by an increase in operations.

Non-operating Income (Expense)

Interest Income. Interest income decreased $207, or 12%, to $1,452 for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. The decrease was primarily due to the reduction in the Company's average investment balance quarter-over-quarter.

Interest Expense. Interest expense decreased $1,864, or 17%, to $9,185 for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. The decrease was due to quarter-over-quarter decreases in debt balances; as well as the partial refinancing of the 2023 Term Loan Credit Facility in December 2024 which resulted in a lower interest rate. These decreases were partially offset by a $391 write-off of the remaining unamortized deferred financing costs in connection with the refinancing of the Company's five Boeing 737-900ER aircraft. For more information on the Company's Debt, see Note 5 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Income Tax. The Company's effective tax rate for the three months ended September 30, 2025 was 28.3% compared to 22.0% for the three months ended September 30, 2024. The effective tax rate in both periods was impacted by permanent stock compensation items.

Total Operating Revenues increased $30,474, or 4%, to $845,808 for the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. The increase was primarily the result of growth in Cargo revenue due to additional aircraft received and operated, as well as contractual rate increases under the A&R ATSA. Revenue for the Passenger business was mostly flat, as growth in the first quarter of 2025 was offset by reduced capacity in the second and third quarters of 2025, as we focused our operations on growth in the Cargo business. These items, as well as other changes to revenue, are discussed in further detail below.

Passenger. Passenger revenue increased $2,831 to $701,654 for the nine months ended September 30, 2025 as compared to the nine months ended September 30, 2024. The table below presents select operating data for lines of revenue within Passenger, expressed as year-over-year changes:

						Nine Months Ended September 30,												% Change
						2025						2024

(1) Percentage point difference

The slight increase in Passenger revenue year-over-year was driven by reduced capacity as we focused our operations on growth in the Cargo business. This resulted in a 6% year-over-year decrease in Scheduled Service departures, which was offset by a 4% increase in total fare per passenger. Ancillary revenues were negatively impacted by the 6% year-over-year decrease in passengers, partially offset by a 2% increase in Ancillary revenue per passenger.

Passenger revenue benefited from the $18,546, or 12%, increase in Charter revenue during the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. This increase was the result of a 10% increase in block hours and a 2% increase in Charter revenue per block hour. The year-over-year increase in block hours was due to an increase in flying by large program customers and ad hoc flying. The improvement in Charter revenue per block hour was primarily driven by rate increases, partially offset by lower fuel recovery revenue due to the year-over-year decrease in fuel cost per gallon.

Cargo. Revenue from cargo services increased $28,423, or 36%, to $106,983 for the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. The increase was primarily due to additional aircraft and contractual rate increases. During the nine months ended September 30, 2025, the Company received and placed in-service all eight additional cargo aircraft under the A&R ATSA.

Other. Other revenue decreased $780, or 2%, to $37,171 for the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. The decrease was primarily driven by lower aircraft lease revenue, partially offset by end of lease compensation revenue recognized during the three months ended June 30, 2025 due to the return of one Owned Aircraft Held for Operating Lease that was previously leased to an unaffiliated airline. For the nine months ended September 30, 2025 and 2024, there were an average of 6

and 7 aircraft on lease to unaffiliated airlines, respectively. For more information, see Note 4 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Operating Expenses

Aircraft Fuel. We believe Aircraft Fuel expense, excluding indirect fuel credits, is the best measure of the effect of fuel prices on our business as it consists solely of direct fuel expenses that are related to our operations and is consistent with how management analyzes our operating performance. This measure is defined as GAAP Aircraft Fuel expense, excluding indirect fuel expenses and credits that are recognized within Aircraft Fuel expense, but are not directly related to our Fuel Cost per Gallon.

The primary components of Aircraft Fuel expense are shown in the following table:

			Nine Months Ended September 30,												% Change
			2025						2024
Total Aircraft Fuel Expense			$	163,738					$	187,229					(13)		%
Indirect Fuel Credits			2,683						1,290						108		%
Aircraft Fuel Expense, Excluding Indirect Fuel Credits			$	166,421					$	188,519					(12)		%
Fuel Gallons Consumed (thousands)			65,169						65,884						(1)		%
Fuel Cost per Gallon, Excluding Indirect Fuel Credits			$	2.55					$	2.86					(11)		%

Aircraft Fuel expense decreased 13% year-over-year due to a 11% decrease in the average fuel cost per gallon and a 1% decrease in consumption.

Salaries, Wages, and Benefits. Salaries, Wages, and Benefits expense increased $32,979, or 14%, to $275,495 for the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. The year-over-year increase in Salaries, Wages, and Benefits was impacted by an 11% increase in employee headcount to support our expanding operations, contractual rate increases for our pilots, and contractual pay increases as a result of new collective bargaining agreements.

Maintenance. Maintenance expense increased $5,106, or 10%, to $55,235 for the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. The year-over-year increase in Maintenance expense was primarily driven by growth in our fleet and operations and higher rates for service. These increases were partially offset by a year-over-year decrease in the number of routine, time-based airframe heavy maintenance events.

Sales and Marketing. Sales and Marketing expense decreased $1,441, or 5%, to $25,378 for the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. The year-over-year decrease was primarily driven by lower booking and credit card transaction fees due to the shift in capacity growth from Scheduled Service to the Cargo business.

Depreciation and Amortization. Depreciation and Amortization expense increased $3,265, or 5%, to $74,459 for the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. The increase was primarily due to an increase in certain capitalized costs associated with two aircraft being returned off of leases, as well as a non-cash expense of $737 due to an unplanned engine retirement.

Ground Handling. Ground Handling expense increased $2,137, or 7%, to $34,227, for the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. This year-over-year

(Unaudited)

increase was the result of rate increases due to market pressures, partially offset by a 3% decrease in Passenger segment departures, as we focused our operations on the growth in Cargo.

Landing Fees and Airport Rent. Landing Fees and Airport Rent increased $4,184, or 9%, to $48,615 for the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. This year-over-year increase was driven by rate increases at airports due to market pressures, primarily at MSP, partially offset by a 3% decrease in Passenger segment departures.

Special Items, net. Special Items, net consisted of $1,874 of ratification bonuses for the new five-year collective bargaining agreement paid to eligible flight attendants during the period, as well as the related payroll tax expense. For more information, see Note 9 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Other Operating, net. Other Operating, net increased $3,374, or 4%, to $84,377 for the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. The increase was primarily the result of an increase in operations, partially offset by increased year-over-year activity from our engine parts sales program.

Non-operating Income (Expense)

Interest Income. Interest income decreased $947, or 16%, to $4,960 for the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. The decrease was primarily due to the reduction in the Company's average investment balance year-over-year.

Interest Expense. Interest expense decreased $5,216, or 16%, to $28,022 for the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. The decrease was due to year-over-year decreases in debt balances, as well as the partial refinancing of the 2023 Term Loan Credit Facility in December 2024 which resulted in a lower interest rate. These decreases were partially offset by a $391 write-off of the remaining unamortized deferred financing costs in connection with the refinancing of the Company's five Boeing 737-900ER aircraft. For more information on the Company's Debt, see Note 5 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Other, net. Other, net expense totaled $488 for the nine months ended September 30, 2025, as a result of the Company incurring expenses of $481 in conjunction with the secondary public offering. Other, net for the nine months ended September 30, 2024 was not material. For more information on the secondary public offering, see Note 10 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Income Tax. The Company's effective tax rate for the nine months ended September 30, 2025 was 24.1% compared to 25.0% for the nine months ended September 30, 2024. The effective tax rate in both periods was impacted by permanent stock compensation items. For more information on the effective tax rate, see Note 8 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Passenger. Passenger Operating Income decreased $974 to $9,719 for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. The Operating Margin Percentage for the three months ended September 30, 2025 decreased by 0.3 percentage point, as compared to the three months ended September 30, 2024. Passenger revenue and total operating expenses decreased quarter-over-quarter due to reduced capacity as we focused our operations on growth in the Cargo business. The quarter-over-quarter decrease in Passenger Operating Income and Operating Margin Percentage were primarily driven by the decrease in revenue, contractual rate increases for our pilots, and contractual pay increases as a result of new collective bargaining agreements. These impacts were partially offset by a 5% decrease in the average fuel cost per gallon and increased quarter-over-quarter activity from our engine parts sales program. For more information on the changes in the components of Operating Income for the Passenger segment, refer to the Results of Operations discussion above.

Cargo. Cargo Operating Income decreased by $1,506, to $183, for the three months ended September 30, 2025, as compared to the three months ended September 30, 2024. Operating Margin Percentage for the three months ended September 30, 2025 decreased by 5.4 percentage points, as compared to the three months ended September 30, 2024. The changes in both Operating Income and Operating Margin Percentage were primarily driven by contractual rate increases, offset by contractual rate increases for our pilots as well as operational challenges as a result of significant growth in the segment. For more information on the components of Operating Income for the Cargo segment, refer to the Results of Operations discussion above.

Non-GAAP Financial Measures

We sometimes use information that is derived from the Condensed Consolidated Financial Statements, but that is not presented in accordance with GAAP. We believe these non-GAAP measures provide a meaningful comparison of our results to others in the airline industry and our prior year results. Investors should consider these non-GAAP financial measures in addition to, and not as a substitute for, our financial performance measures prepared in accordance with GAAP. Further, our non-GAAP information may be different from the non-GAAP information provided by other companies. We believe certain charges included in our operating expenses on a GAAP basis make it difficult to compare our current period results to prior periods as well as future periods and guidance. The tables below show a reconciliation of non-GAAP financial measures used in this report to the most directly comparable GAAP financial measures.

Adjusted Operating Income, Adjusted Operating Income Margin, Adjusted Net Income and Adjusted EBITDA

Adjusted Operating Income, Adjusted Operating Income Margin, Adjusted Net Income, and Adjusted EBITDA are non-GAAP measures included as supplemental disclosure because we believe they are useful indicators of our operating performance. Derivations of Operating Income and Net Income are well recognized performance measurements in the airline industry that are frequently used by our management, as well as by investors, securities analysts and other interested parties in comparing the operating performance of companies in our industry.

The measures described above have limitations as analytical tools. Some of the limitations applicable to these measures include: they do not reflect the impact of certain cash and non-cash charges resulting from matters we consider not to be indicative of our ongoing operations; and other companies in our industry may calculate these non-GAAP measures differently than we do, limiting each measure’s usefulness as a comparative measure. Because of these limitations, the following non-GAAP measures should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP and may not be the same as or comparable to similarly titled measures presented by other companies due to the possible differences in the method of calculation and in the items being adjusted.

For the foregoing reasons, Adjusted Operating Income, Adjusted Operating Income Margin, Adjusted Net Income and Adjusted EBITDA have significant limitations which affect their use as indicators of our profitability. Accordingly, readers are cautioned not to place undue reliance on this information.

_________________________

(1)			The adjustments include Special Items, net, as included in Note 9 of these Condensed Consolidated Financial Statements.
(2)			In July 2025, an engine experienced an IFSD. The engine was subsequently deemed beyond economic repair, which resulted in a $737 non-cash expense due to an unplanned engine retirement. The Company recognized the $737 non-cash expense within Depreciation and Amortization. Management does not consider this activity in assessing its operational performance.

CASM and Adjusted CASM

CASM is a key airline cost metric defined as operating expenses divided by total available seat miles. Adjusted CASM is a non-GAAP measure derived from CASM by excluding fuel costs, costs related to our cargo operations, depreciation and amortization recognized on certain assets that generate lease income, certain unplanned engine events, stock-based compensation, certain commissions and other costs of selling our vacation products from this measure as these costs are unrelated to our airline operations and improve comparability to our peers. Adjusted CASM is an important measure used by management and our Board of Directors in assessing quarterly and annual cost performance. Adjusted CASM is commonly used by industry analysts and we believe it is an important metric by which they compare our airline to others in the industry, although other airlines may exclude certain other costs in their calculation of Adjusted CASM. The measure is also the subject of frequent questions from investors.

Adjusted CASM excludes fuel costs. By excluding volatile fuel expenses that are outside of our control from our unit metrics, we believe that we have better visibility into the results of operations and our non-fuel cost initiatives. Our industry is highly competitive and is characterized by high fixed costs, so even a small reduction in non-fuel operating costs can lead to a significant improvement in operating results. In addition, we believe that all domestic carriers are similarly impacted by changes in jet fuel costs over the long run, so it is important for management and investors to understand the impact and trends in company-specific cost drivers, such as labor rates, aircraft costs and maintenance costs, and productivity, which are more controllable by management.

We have excluded costs related to the Cargo operations, as well as depreciation and amortization recognized on certain assets that generate lease income as these operations do not create ASMs. The Cargo expenses in the reconciliation below are different from the total operating expenses for our Cargo segment in the “Segment Information” table presented above, due to several items that are included in the Cargo segment, but have been captured in other line items used in the Adjusted CASM calculation. The Company has entered into certain transactions where it serves as a lessor. As of September 30, 2025, we leased or subleased five aircraft.

Adjusted CASM further excludes special items and other adjustments, as defined in the relevant reporting period, that are not representative of the ongoing costs necessary to our airline operations and may improve comparability between periods. We also exclude stock compensation expense when computing Adjusted CASM. The Company’s compensation strategy includes the use of stock-based compensation to attract and retain employees and executives and is principally aimed at aligning their interests with those of our stockholders and long-term employee retention, rather than to motivate or reward operational performance for any period. Thus, stock-based compensation expense varies for reasons that are generally unrelated to operational decisions and performance in any period.

As derivations of Adjusted CASM are not determined in accordance with GAAP, such measures are susceptible to varying calculations and not all companies calculate the measures in the same manner. As a result, derivations of Adjusted CASM as presented may not be directly comparable to similarly titled measures presented by other companies. Adjusted CASM should not be considered in isolation or as a replacement for CASM. For the aforementioned reasons, Adjusted CASM has significant limitations which affect its use as an indicator of our profitability. Accordingly, readers are cautioned not to place undue reliance on this information.

Liquidity and Capital Resources

Our primary sources of liquidity as of September 30, 2025 included our existing cash and cash equivalents of $111,834 and short-term investments of $64,391, our expected cash generated from operations, the $75,000 of available funds under the Revolving Credit Facility, and the remaining $54,000 of financing available through the 2025 Term Loan Facility. We invest cash and cash equivalents in highly liquid securities with strong credit ratings. We classify our investments as current assets because of their highly liquid nature and availability to be converted into cash to fund current operations. Given the significant portion of our portfolio held in cash and cash equivalents and the high credit quality of our debt security investments, we do not anticipate fluctuations in the aggregate fair value of our investments to have a material impact on our liquidity or capital position.

In addition, we had restricted cash of $22,998 as of September 30, 2025, which generally consists of cash received as prepayment for chartered flights that is maintained in separate escrow accounts prior to the date of transportation in accordance with DOT regulations. The restrictions are released once the charter transportation is provided.

We believe our unrestricted cash and cash equivalents, short-term investments, and availability under our Revolving Credit Facility and 2025 Term Loan Facility, combined with expected future cash flows from operations, will be sufficient to fund our operations and meet our debt payment obligations for at least the next 12 months. However, we cannot predict what the effect on our business and financial position might be from a change in the competitive environment in which we operate or from events beyond our control, such as volatile fuel prices, economic conditions, pandemics, weather-related disruptions, the impact of airline bankruptcies, restructurings or consolidations, U.S. military actions, regulations, or acts of terrorism.

For a more detailed discussion on our Liquidity and Capital Resources, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 in our 2024 10-K.

Aircraft – We do not maintain an aircraft order book; instead, we enter into aircraft transactions on an opportunistic basis based on market conditions, our prevailing level of liquidity and capital market availability. As a result, we are not locked into large future capital expenditures. We have historically financed aircraft through debt and finance leases. As of September 30, 2025, our fleet consisted of 70 Boeing 737-NG aircraft. This includes 45 aircraft in the passenger fleet, 20 cargo aircraft operated pursuant to the A&R ATSA, and five aircraft currently on lease to unaffiliated airlines.

During the nine months ended September 30, 2025, the Company received and placed in-service all eight additional cargo aircraft under the A&R ATSA. For more information on our fleet, see Note 4 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Maintenance Deposits - In addition to funding the acquisition of aircraft, we are required by certain of our aircraft lessors to fund cash reserves in advance for scheduled maintenance to act as collateral for the benefit of the lessors. Qualifying payments that are expected to be recovered from lessors are recorded as Lessor Maintenance Deposits on our Condensed Consolidated Balance Sheets. As of September 30, 2025, we had $64,545 of total Lessor Maintenance Deposits. All maintenance deposits as of September 30, 2025 are estimated to be recoverable either through reimbursable maintenance events or through application towards the purchase of the aircraft.

Credit Facilities - We use our Credit Facilities to provide liquidity for general corporate purposes and to finance the acquisition of aircraft. In March 2025, the Company executed a new $75,000 Revolving Credit Facility with a group of lenders. The new Revolving Credit Facility replaces the Company's previous $25,000 revolving credit facility. The Company pledged certain assets, including certain previously unencumbered aircraft, to support the ability to efficiently utilize the Revolving Credit Facility. As of September 30, 2025, the Company had $75,000 of financing available through the Revolving Credit Facility. The Company was in compliance with its covenants within the Revolving Credit Facility as of September 30, 2025.

Debt - At our discretion, we obtain debt financing in order to purchase or refinance aircraft.

In September 2025, the Company executed the 2025 Term Loan Facility with a face amount of $108,000 for the purpose of refinancing the Company's five Boeing 737-900ER aircraft, of which three are on lease to an unaffiliated airline. The Company's five Boeing 737-900ERs are pledged as collateral. During the three months ended September 30, 2025, the Company drew $54,000 from the 2025 Term Loan Facility. The proceeds were used to repay the full outstanding balance of the 2023 Term Loan Credit Facility, with the remainder to be used for general corporate purposes. The 2025 Term Loan Facility is repaid quarterly through September 2032. As of September 30, 2025, the Company had $54,000 of financing available through the 2025 Term Loan Facility. All remaining financing through the 2025 Term Loan Facility must be drawn by December 19, 2025.

For more information on our credit facilities or debt, see Note 5 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

TRA Liability - During the nine months ended September 30, 2025 and 2024, we made payments of $10,525 and $3,350 to the TRA holders, respectively. Payments will be made in future periods as Pre-IPO Tax Attributes are utilized. For more information on the TRA liability, see Note 8 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Operating Cash Flow Activities

Operating activities in the nine months ended September 30, 2025 provided $78,201, as compared to $74,303 during the nine months ended September 30, 2024. During the nine months ended September 30, 2025, our Net Income was $44,664, as compared to $39,467 during the nine months ended September 30, 2024.

Our operating cash flow is primarily impacted by the following factors:

Seasonality of Advance Ticket Sales. We sell tickets for air travel in advance of the customer's travel date. When we receive a cash payment at the time of sale, we record the cash received on advance sales as deferred revenue in Air Traffic Liabilities. Air Traffic Liabilities typically increase during the fall and early winter months as advanced ticket sales grow prior to the late winter and spring peak travel season and decrease during the summer months. Most tickets can be purchased no more than 12 months in advance, therefore any revenue associated with tickets sold for future travel will be recognized within that timeframe. For the nine months ended September 30, 2025, $155,471 of revenue recognized in Passenger revenue was included in the $160,686 of Air Traffic Liabilities as of December 31, 2024. Air Traffic Liabilities decreased to $144,430 as of September 30, 2025 as a result of decreased Scheduled Service capacity as we focused our operations on growth in the Cargo business.

Aircraft Fuel. Aircraft Fuel expense represented approximately 21% and 25% of our total operating expense for the nine months ended September 30, 2025 and 2024, respectively. The market price for jet fuel is volatile, which can impact the comparability of our periodic cash flows from operations. Fuel cost per gallon decreased

(Unaudited)

by 11% year-over-year. Fuel consumption decreased by 1% during the nine months ended September 30, 2025, compared to the prior year as a result of the operational shift in capacity from Scheduled Service to the Cargo business. We expect continued volatility in Aircraft Fuel prices per gallon due to market conditions and global geopolitical events.

Investing Cash Flow Activities

Capital Expenditures. Our capital expenditures were $29,140 and $42,615 for the nine months ended September 30, 2025 and 2024, respectively. Our capital expenditures during the nine months ended September 30, 2025 included the acquisition of one engine, spare parts, ground equipment, and other items not individually material. Our capital expenditures during the nine months ended September 30, 2024 included the acquisition of one aircraft and other items not individually material.

Investments. The Company's net investment activity resulted in cash inflows of $39,869 during the nine months ended September 30, 2025, as compared to cash inflows of $52,095 during the nine months ended September 30, 2024. The year-over-year change is a result of a reduction in the Company's average investment balance in order to support general corporate purposes and debt repayments.

Financing Cash Flow Activities

Debt. At our discretion, we obtain debt financing in order to purchase or refinance aircraft. In September 2025, the Company executed the 2025 Term Loan Facility with a face amount of $108,000 for the purpose of refinancing the Company's five Boeing 737-900ER aircraft, of which three are on lease to an unaffiliated airline. The 2025 Term Loan Facility is repaid quarterly through September 2032. As of September 30, 2025, the Company had $54,000 of financing available through the 2025 Term Loan Facility. For more information on our debt financings and future repayment schedules, see Note 5 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Finance Leases. Our repayments of finance lease obligations were $15,010 and $26,249 for the nine months ended September 30, 2025 and 2024, respectively. During the nine months ended September 30, 2024, the Company purchased an aircraft previously classified as a finance lease. The resulting cash outflows of $9,670 were recorded as payments for finance lease obligations. As of September 30, 2025 and 2024, the Company had 13 and 15 aircraft finance leases, respectively.

Common Stock Repurchases. During the nine months ended September 30, 2025, the Company repurchased 1,474,021 shares of its Common Stock at a weighted-average price of $13.58 per share. During the nine months ended September 30, 2024, the Company repurchased 755,284 shares of its Common Stock at a weighted-average price of $15.22 per share. For more information on the stock repurchase program, see Note 10 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

TRA Payment. During the nine months ended September 30, 2025 and 2024, the Company made payments of $10,525 and $3,350 to the TRA holders, respectively. For more information on the payment of the TRA, see Note 8 of the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Off Balance Sheet Arrangements

ITEM 5. OTHER INFORMATION

Executive Employment Agreements

On October 27, 2025, in connection with its ongoing holistic review of the Company’s executive compensation arrangements, and in furtherance of continuing to more appropriately align the Company’s executive compensation arrangements with those of other steady-state public companies, the Compensation Committee of the Board of Directors approved new executive employment letters (the “Executive Employment Letters”) for certain of its senior leadership team members, including D. Torque Zubeck and Rose Neale (the “Executive Officers”).
