Notes to Condensed Consolidated Financial Statements
September 30, 2025
(Unaudited)
Unless the context requires otherwise, references to the “Company,” “WLFC,” “we,” “us” or “our” in this Quarterly Report on Form 10-Q refer to Willis Lease Finance Corporation and its subsidiaries .
1. Summary of Significant Accounting Policies

The significant accounting policies of the Company were described in Note 1 to the Audited Consolidated Financial Statements included in the Company’s 2024 Form 10-K. There have been no significant changes in the Company’s significant accounting policies for the nine months ended September 30, 2025.

(a) Basis of Presentation

The accompanying Unaudited Condensed Consolidated Financial Statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”), consistent in all material respects with those applied in the 2024 Form 10-K, for interim financial information and in accordance with the rules and regulations of the SEC. Therefore, they do not include all information and footnotes normally included in annual consolidated financial statements and should be read in conjunction with the consolidated financial statements and notes thereto included in the 2024 Form 10-K. In the opinion of management, the Unaudited Condensed Consolidated Financial Statements contain all adjustments (consisting principally of normal recurring accruals) necessary for a fair presentation of the Condensed Consolidated Balance Sheets, Statements of Income, Statements of Comprehensive Income, Statements of Redeemable Preferred Stock and Shareholders’ Equity, and Statements of Cash Flows for such interim periods presented. Operating results for interim periods are not necessarily indicative of the results that can be expected for a full year.

In accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements, giving due consideration to materiality. These estimates and judgments are based on historical experience and other assumptions that management believes are reasonable and take into account the economic implications of the potential impact of changes in interest rates or inflation, as well as the impact of new or increased tariffs, on the Company’s critical and significant accounting estimates. However, application of these accounting policies involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, actual results could differ materially from these estimates. The significant estimates made in the accompanying Unaudited Condensed Consolidated Financial Statements include certain assumptions related to intangible assets, long-lived assets, equipment held for sale, allowances for doubtful accounts and credit losses, inventory, deferred in-substance fixed payment use fees included in Unearned revenue on the Condensed Consolidated Balance Sheets, and estimated income taxes. Actual results may differ materially from these estimates under different assumptions or conditions. Given the uncertainty in the future changes in interest rates or inflation, as well as the impact of new or increased tariffs, the Company will continue to evaluate the nature and extent of the impact to its business, results of operations and financial condition.

(b) Principles of Consolidation

The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries, including VIEs, where the Company is the primary beneficiary in accordance with consolidation guidance. The Company first evaluates all entities in which it has an economic interest to determine whether for accounting purposes the entity is either a VIE or a voting interest entity. If the entity is a VIE, the Company consolidates the financial statements of that entity if it is the primary beneficiary of such entity’s activities. If the entity is a voting interest entity, the Company consolidates the financial statements of that entity when it has a majority of voting interests in such entity. Intercompany transactions and balances have been eliminated in consolidation.

Given the uncertainty in the rapidly changing market and economic conditions related to the potential impact of changes in interest rates or inflation, as well as the impact of new or increased tariffs, we will continue to evaluate the nature and extent of the impact on the Company’s business and financial position. The ultimate extent of the effects on the Company will depend on future developments, and such effects could exist for an extended period of time.

(d) Recent Accounting Pronouncements

Recent Accounting Pronouncements To Be Adopted by the Company

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” Under the ASU, public business entities must annually (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than five percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). The amendments in this ASU are effective for public business entities for annual periods beginning after December 15, 2024, with early adoption permitted. The Company expects to adopt this accounting standard update for the year ended December 31, 2025, and the Company does not expect the adoption of this guidance to have a significant impact on the consolidated financial statement disclosures.

In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-04) Disaggregation of Income Statement Expenses.” The ASU requires public entities, on both an interim and annual basis, to disclose additional disaggregated information about specific expense categories in the notes to the financial statements. The ASU is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company expects to adopt this accounting standard update for the year ended December 31, 2027 and is currently evaluating the potential effects on the consolidated financial statements and related disclosures.

In July 2025, the FASB issued ASU 2025-05, “Measurement of Credit Losses for Accounts Receivable and Contract Assets.” The ASU provides public entities with a practical expedient when estimating expected credit losses for accounts receivable and contract assets. The practical expedient assumes that current conditions of the balance sheet do not change for the remaining life of the asset. The ASU is effective for fiscal years beginning after December 15, 2025, with early adoption permitted. The Company expects to adopt this accounting standard update for the year ended December 31, 2026, and the Company does not expect the adoption of this guidance to have a significant impact on the consolidated financial statements.

(e) Government Grant Income

There is no specific guidance in GAAP that addresses the recognition and measurement of government assistance received by a business entity. In the absence of authoritative GAAP guidance, the Company considered the application of other authoritative accounting guidance by analogy and concluded that the guidance outlined in International Accounting Standard 20 – Accounting for Government Grants and Disclosures of Government Assistance (“IAS 20”) was the most appropriate. Under IAS 20, grant income is recognized to the extent that there is reasonable assurance that the Company will comply with the conditions attached to the grant, and the grant will be received.

During the three months ended September 30, 2025, the Company did not receive government grant receipts. During the nine months ended September 30, 2025, the Company received approximately $ 6.3 million in government grant receipts for its sustainable aviation fuel project, related to a grant that was awarded to the Company in October 2023. As of September 30, 2025, the Company believes it has complied and will continue to comply with all of the grant conditions, which primarily relate to providing evidence of completion of the funded activities. The grant income was recorded as a deduction to related fees included in general and administrative expenses on the Condensed Consolidated Statements of Income.

3. Investments

In 2011, the Company entered into an agreement with Mitsui & Co., Ltd. to participate in a joint venture formed as a Dublin-based Irish limited company, Willis Mitsui & Company Engine Support Limited (“WMES”), for the purpose of acquiring and leasing jet engines. Each partner holds a 50 % interest in the joint venture, and the Company uses the equity method in recording investment activity. As of September 30, 2025, WMES owned a lease portfolio of 53 engines and one aircraft with a net book value of $ 364.1 million.

In 2014, the Company entered into an agreement with China Aviation Supplies Import & Export Corporation (“CASC”) to participate in a joint venture named CASC Willis Engine Lease Company Limited (“CASC Willis”), a joint venture based in Shanghai, China. Each partner holds a 50 % interest in the joint venture, and the Company uses the equity method in recording investment activity. CASC Willis acquires and leases jet engines to Chinese airlines and concentrates on the demand for leased commercial aircraft engines and aviation assets in the People’s Republic of China. As of September 30, 2025, CASC Willis owned a lease portfolio of six engines with a net book value of $ 50.0 million.
In March 2025, the Company entered into an agreement with independent MRO (Maintenance, Repair and Overhaul) provider Global Engine Maintenance to create a joint venture named Willis Global Engine Testing (“WGET”) to build an engine test facility in West Palm Beach, Florida. The Company has a 70 % membership interest, and Global Engine Maintenance has a 30 % membership interest. WGET is a VIE that the Company is not the primary beneficiary of since the power to direct the activities that most significantly impact WGET’s economic performance is shared between the Company and Global Engine Maintenance. The Company’s considerations in determining the VIE’s most significant activities and whether the Company has the power to direct those activities include, but are not limited to, the VIE’s purpose and design and the matters that require unanimous approval from both parties. Accordingly, the Company does not consolidate WGET, and the Company uses the equity method in recording investment activity. The Company made an initial capital contribution of $ 1.6 million, which represents 70 % of the cost of the land that the engine test facility is being built on. WGET signed a contract related to the design of an engine test facility. The Company anticipates its portion of the remaining committed amount, which will be funded through future contributions, to be approximately $ 27.2 million.

During the nine months ended September 30, 2025, Willis Asset Management Limited (“WAML”), a wholly-owned subsidiary of the Company entered into a Share Purchase Agreement (the “SPA”), by and between WAML and WMES. Pursuant to the SPA, WAML sold the entire issued share capital of Bridgend Asset Management Limited (“BAML”), a United Kingdom-based aviation consultancy business, to WMES for a total purchase price of $ 45.0 million subject to certain working capital adjustments. The transaction closed on June 30, 2025, resulting in a gain on sale of business of approximately $ 43.0 million for the Company.

As of September 30, 2025, the Company subleased two WMES engines to a third party, with WMES as the head lessor. As of September 30, 2025, the total right-of-use (“ROU”) asset and lease liability balances under these leases were $ 0.8 million and $ 0.7 million, respectively. As of December 31, 2024, the Company subleased one WMES engine to a third party, with WMES as the head lessor. As of December 31, 2024, the ROU asset and lease liability balances under this lease were $ 1.6 million, each.

As it relates to the $ 20.6 million, $ 21.7 million, $ 17.6 million, $ 23.7 million, $ 20.9 million, and $ 19.7 million notes payable resulting from failed sale-leaseback transactions that are secured by engines, the Company has options to repurchase the engines in March 2032 for $ 18.4 million, January 2032 for $ 17.7 million, July 2031 for $ 17.0 million, March 2032 for $ 19.3 million, March 2033 for $ 16.9 million, and April 2033 for $ 17.9 million, respectively.

In June 2025, the Company and its direct, wholly-owned subsidiary Willis Engine Structured Trust VIII (“WEST VIII”), closed WEST VIII’s offering of $ 596.0 million in aggregate principal amount of fixed rate notes (the “Notes”). The Notes were issued in two series, with the Series A Notes issued in an aggregate principal amount of $ 524.0 million and the Series B Notes issued in an aggregate principal amount of $ 72.0 million. The Notes are secured by, among other things, WEST VIII’s direct and indirect ownership interests in a portfolio of aircraft engines and airframes. The Series A Notes and Series B Notes have a fixed coupon of 5.582% and 6.070 %, respectively, an expected maturity of approximately six years and a final maturity of 25 years. The Series A Notes and Series B Notes were issued at a price of 99.99721 % and 99.99711 % of par, respectively.

In July 2025, Willis Warehouse Facility LLC (the “Borrower”), a wholly owned subsidiary of the Company, entered into Amendment No. 1 to the Secured Credit Agreement (the “Amended Credit Agreement”). The Amended Credit Agreement primarily includes the following changes, among other things, (i) an extension of the availability period of the commitments from May 3, 2026, to May 3, 2027, (ii) an extension of the final repayment date from May 3, 2029 to May 3, 2030, (iii) more favorable asset advance rates available to the Borrower, and (iv) reduced fees.

Principal outstanding at September 30, 2025 is expected to be repayable as follows:

Virtually all of the above debt requires ongoing compliance with certain financial covenants, including debt and tangible net worth ratios, minimum interest coverage ratios, and other eligibility criteria including asset type, customer and geographic concentration restrictions. The Company also has certain negative financial covenant obligations that relate to such items as liens, advances, changes in business, sales of assets, dividends and stock repurchases. Compliance with these covenants is tested either monthly, quarterly or annually, as required, and the Company was in full compliance with all financial covenant requirements at September 30, 2025.
5. Derivative Instruments

The Company periodically holds interest rate derivative instruments to mitigate exposure to changes in interest rates, predominantly one-month term SOFR, with $ 581.8 million and $ 914.9 million of variable rate borrowings at September 30, 2025 and December 31, 2024, respectively. As a matter of policy, management does not use derivatives for speculative purposes. As of September 30, 2025, the Company had five interest rate swap agreements, with a total notional amount of $ 334.5 million. During 2021, the Company entered into four fixed-rate interest swap agreements, each having notional amounts of $ 100.0 million, two of which matured during the year ended December 31, 2024 and two of which had remaining terms of four months as of September 30, 2025. During the year ended December 31, 2024, the Company entered into three fixed-rate interest swap agreements, each having notional amounts of $ 50.0 million, two of which were terminated during the nine months ended September 30, 2025 and one of which had a remaining term of 44 months as of September 30, 2025. During the year ended December 31, 2024, the Company also entered into one fixed-rate interest swap agreement, which had a notional amount of $ 75.0 million. During the nine months ended September 30, 2025, this fixed-rate interest swap agreement was partially terminated, reducing its notional amount to $ 34.5 million. It had a remaining term of 44 months as of September 30, 2025. During the nine months ended September 30, 2025, the Company entered into one fixed-rate interest swap agreement, having a notional amount of $ 50.0 million, and with a remaining term of 49 months as of September 30, 2025. The derivative instruments were each designated as cash flow hedges at inception and recorded at fair value.

The following table displays the total notional amount of the Company’s outstanding fixed-rate interest swap agreements:

Derivatives in Cash Flow Hedging Relationships As of September 30, As of December 31,
2025 2024
(in thousands)
Interest rate contracts $ 334,500 $ 425,000

The Company evaluated the effectiveness of the swap agreements to hedge the interest rate risk associated with its variable rate debt and concluded at the swap inception dates that each swap was highly effective in hedging that risk. The Company evaluates the effectiveness of the hedging relationships on an ongoing basis and concluded there was no ineffectiveness in the hedges for the period ended September 30, 2025.

The Company estimates the fair value of derivative instruments using a discounted cash flow technique. Valuation of the derivative instruments requires certain assumptions for underlying variables and the use of different assumptions would result in a different valuation. Management believes it has applied assumptions consistently during the period. The Company applies hedge accounting and accounts for the change in fair value of its cash flow hedges through other comprehensive income for all derivative instruments that are effective and for which the related forecasted transaction is probable of occurring.

The following table displays the total pre-tax loss reclassified from accumulated other comprehensive income (“AOCI”) to earnings as a result of the terminations of the interest rate derivative instruments described above, as these forecasted transactions were no longer probable of occurring:

The Company recorded an adjustment to interest expense of $( 4.4 ) million and $( 9.2 ) million during the nine months ended September 30, 2025 and 2024, respectively, from derivative instruments.

Effect of Derivative Instruments on Earnings on the Condensed Consolidated Statements of Income and Comprehensive Income

The following table provides additional information about the financial statement effects related to the cash flow hedges for the three and nine months ended September 30, 2025 and 2024:
Derivatives in Cash Flow Hedging Relationships Amount of Loss Recognized in OCI on Derivatives
(Effective Portion)
Three months ended September 30, Nine months ended September 30,
2025 2024 2025 2024
(in thousands)
Interest rate contracts $ ( 3,131 ) $ ( 7,277 ) $ ( 12,096 ) $ ( 10,673 )
Total $ ( 3,131 ) $ ( 7,277 ) $ ( 12,096 ) $ ( 10,673 )

The effective portion of the change in fair value on a derivative instrument designated as a cash flow hedge is reported as a component of other comprehensive income and is reclassified into earnings in the period during which the transaction being hedged affects earnings when it is determined to be improbable that the forecasted transaction will occur. The ineffective portion of the hedges, if any, is recorded in earnings in the current period.

Counterparty Credit Risk

The Company evaluates the creditworthiness of the counterparties under its hedging agreements. The counterparties for the interest rate swaps are large financial institutions that possess investment grade credit ratings. Based on these ratings, the Company believes that the counterparties are credit-worthy and that their continuing performance under the hedging agreements is probable and does not require the counterparties to provide collateral or other security to the Company.
6. Commitments, Contingencies, Guarantees and Indemnities

Other obligations

Other obligations, such as certain purchase obligations are not recognized as liabilities in the consolidated financial statements but are required to be disclosed in the footnotes to the financial statements. As of September 30, 2025, the Company had $ 1.0 billion in purchase commitments of equipment that are expected to be satisfied within five fiscal years. The purchase obligations are subject to escalation based on the closing date of each transaction. Our purchase agreements generally contain terms that allow the Company to defer or cancel purchase commitments in certain situations. These deferrals or cancellations would not result in penalties or increased costs other than any potential increase due to the normal year-over-year change in engine list prices, which is akin to ordinary inflation.

In December 2020, we entered into definitive agreements for the purchase of 25 Pratt & Whitney aircraft engines. As part of the purchase, we have committed to certain future overhaul and maintenance services which are anticipated to range between $ 97.1 million and $ 126.8 million by 2030.
7. Income Taxes

Income tax expense for the three and nine months ended September 30, 2025 was $ 18.9 million and $ 41.2 million, respectively. The effective tax rate for the three and nine months ended September 30, 2025 was 43.7 % and 28.9 %, respectively. Income tax expense for the three and nine months ended September 30, 2024 was $ 10.4 million and $ 34.7 million, respectively. The effective tax rate for the three and nine months ended September 30, 2024 was 30.1 % and 28.4 % respectively. The Company’s effective tax rates differed from the U.S. federal statutory rate of 21.0% primarily due to executive compensation exceeding $1.0 million as defined in Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), as well as the sale of the Company’s entire issued share capital of BAML, a discrete item per ASC 270, “Interim Reporting,” due to the unusual and infrequent nature of the sale. H.R. 1., also known as the One Big Beautiful Bill Act (“OBBBA”), was enacted on July 4, 2025. The provisions of the OBBBA impacted certain tax deductions, including bonus depreciation, limiting the Company’s ability to benefit from the Section 250 deduction. This disallowance caused the Company’s third quarter effective tax rate to be higher than that of the previous quarter.

The Company records tax expense or benefit for unusual or infrequent items discretely in the period in which they occur. The Company’s tax rate is subject to change based on changes in the mix of assets leased to domestic and foreign lessees, the proportion of revenue generated within and outside of California, the amount of executive compensation exceeding $1.0 million as defined in Section 162(m) of the Code, and numerous other factors, including changes in tax law.

8. Fair Value Measurements

The fair value of a financial instrument represents the amount at which the instrument could be exchanged in a current transaction between willing parties in contrast to a forced sale or liquidation. Fair value estimates are made at a specific point in time, based on relevant market information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of judgment, and therefore cannot be determined with precision.

Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Accounting standards establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value and also establishes the following three levels of inputs that may be used to measure fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The following methods and assumptions were used by the Company in estimating fair value disclosures for financial instruments:

Cash and cash equivalents, restricted cash, receivables, and accounts payable : The amounts reported in the accompanying Condensed Consolidated Balance Sheets approximate fair value due to their short-term nature.

Notes receivable : The carrying amount of the Company’s outstanding balance on its Notes receivable as of September 30, 2025 and December 31, 2024 was estimated to have a fair value of approximately $ 143.3 million and $ 176.7 million, respectively, based on the fair value of estimated future payments calculated using interest rates that approximate prevailing market rates at each period end (Level 2 inputs).

Investments in sales-type leases: The carrying amount of the Company’s outstanding balance on its Investments in sales-type leases as of September 30, 2025 and December 31, 2024 was estimated to have a fair value of approximately $ 16.5 million and $ 21.5 million, respectively, based on the fair value of estimated future payments calculated using interest rates that approximate prevailing market rates at each period end (Level 2 inputs).

Debt obligations : The carrying amount of the Company’s outstanding balance on its Debt obligations as of September 30, 2025 and December 31, 2024 was estimated to have a fair value of approximately $ 1,986.5 million and $ 1,928.3 million, respectively, based on the fair value of estimated future payments calculated using interest rates that approximate prevailing market rates at each period end (Level 2 inputs).

21

Assets Measured and Recorded at Fair Value on a Recurring Basis and a Nonrecurring Basis

As of September 30, 2025 and December 31, 2024, the Company measured the fair value of its interest rate swap agreements based on Level 2 inputs, due to the usage of inputs that can be corroborated by observable market data. The Company estimates the fair value of derivative instruments using a discounted cash flow technique. The net fair value of the interest rate swaps as of September 30, 2025 was $ 1.9 million, representing an asset of $ 2.2 million and a liability of $ 0.3 million, and reflected within Other assets and Accounts payable and accrued expenses on the Condensed Consolidated Balance Sheets, respectively. The net fair value of the interest rate swaps as of December 31, 2024 was $ 11.0 million, representing an asset and reflected within Other assets on the Condensed Consolidated Balance Sheets. The Company recorded an adjustment to interest expense of $ 0.5 million and $( 3.0 ) million during the three months ended September 30, 2025 and 2024, respectively, from derivative instruments. The Company recorded an adjustment to interest expense of $( 4.4 ) million and $( 9.2 ) million during the nine months ended September 30, 2025 and 2024, respectively, from derivative instruments.

Goodwill is assessed for impairment annually, at each year end by comparing the fair values of the reporting units to their carrying amounts. The Company first assesses qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test.

The Company determines fair value of long-lived assets held and used, such as Equipment held for operating lease and Equipment held for sale, by reference to independent appraisals, quoted market prices (e.g. an offer to purchase) and other factors. An impairment charge is recorded when the carrying value of the asset exceeds its fair value. The Company uses Level 2 inputs to measure write-downs of equipment held for lease and equipment held for sale.

Write-downs of equipment to their estimated fair values totaled $ 10.2 million for the three months ended September 30, 2025, reflecting the adjustments of the carrying values of eight engines. Write-downs of equipment to their estimated fair values totaled $ 23.8 million for the nine months ended September 30, 2025, reflecting the adjustment of the carrying value of 19 engines. Write-downs of equipment to their estimated fair values totaled $ 0.6 million for the three months ended September 30, 2024, reflecting the adjustments of the carrying values of three engines. Write-downs of equipment to their estimated fair values totaled $ 0.9 million for the nine months ended September 30, 2024, reflecting the adjustment of the carrying value of one airframe and three engines.
9. Earnings Per Share

Basic earnings per common share is computed by dividing net income, less preferred stock dividends and accretion of preferred stock issuance costs, by the weighted average number of common shares outstanding for the period. Treasury stock is excluded from the weighted average number of shares of common stock outstanding. Diluted earnings per share attributable to common stockholders is computed based on the weighted average number of shares of common stock and dilutive securities outstanding during the period. Dilutive securities are common stock equivalents that are freely exercisable into common stock at less than market prices or otherwise dilute earnings if converted. The net effect of common stock equivalents is based on the incremental common stock that would be issued upon the vesting of restricted stock using the treasury stock method. Common stock equivalents are not included in diluted earnings per share when their inclusion is antidilutive. Additionally, redeemable preferred stock is not convertible and does not affect dilutive shares.

There were approximately 136,000 and 266,000 anti-dilutive weighted shares excluded from the computation of diluted weighted average income per common share for the three and nine months ended September 30, 2025, respectively. There were no anti-dilutive shares for the three months ended September 30, 2024. There were approximately 900 anti-dilutive weighted shares excluded from the computation of diluted weighted average income per common share for the nine months ended September 30, 2024.

10. Equity

Common Stock Repurchase

In December 2024, the Board of Directors (the “Board”) approved the renewal of the existing common stock repurchase plan which allows for repurchases of up to $ 60.0 million of the Company’s common stock, extending the plan through December 31, 2026. Repurchased shares are immediately retired. No shares were repurchased during each of the nine months ended September 30, 2025 and 2024, and we maintain authority to repurchase up to $ 60.0 million of common stock under the plan.

Redeemable Preferred Stock

In September 2024, the Company entered into a Series A Preferred Stock Purchase Agreement with Development Bank of Japan Inc. (the “Stock Purchase Agreement”), which refinanced and expanded the Company’s Series A-1 and Series A-2 Preferred Stock into one $ 65.0 million Series A Preferred Stock series (the “Series A Preferred Stock”), which accrues quarterly dividends at the rate per annum of 8.35 % per share. The net proceeds after deducting issuance costs were $ 13.1 million.

The rights and privileges of the Series A Preferred Stock are described below:

Voting Rights : Holders of the Series A Preferred Stock do not have general voting rights.

Dividends : Prior to the Stock Purchase Agreement, the Company’s Series A-1 Preferred Stock accrued quarterly dividends at the rate per annum of 8.5 % per share, and the Series A-2 Preferred Stock accrued quarterly dividends at the rate per annum of 6.5 % per share. During each of the nine months ended September 30, 2025 and 2024, the Company paid total preferred stock dividends of $ 4.3 million and $ 3.4 million, respectively. As of September 30, 2025, the Company had approximately $ 1.1 million in preferred stock dividends accrued but not paid, or approximately $ 0.35 per share of the Series A Preferred Stock.

Liquidation Preference : The holders of the Series A Preferred Stock have preference in the event of any voluntary or involuntary liquidation, dissolution, or winding-up of the corporation, including a merger or consolidation. Upon such liquidation event, the Preferred Stockholders are entitled to be paid out of the assets of the Company available for distribution to its stockholders after payment of all the Company’s indebtedness and other obligations and before any payment shall be made to the holders of common stock or any other class or series of stock ranking on liquidation junior to the Preferred Stock an amount equal to $ 20.00 per share, plus any declared but unpaid dividends.

Redemption: The Series A Preferred Stock has no stated maturity date. The holders of the Series A Preferred Stock have the option to require the Company to redeem all or any portion of the Series A Preferred Stock for cash upon occurrence of any of the following: (i) a material breach of the Stock Purchase Agreement, (ii) changes in the ownership structure of the Company, including by means of a change of control transaction, (iii) incurrence of operating loss or ordinary loss by the Company for two consecutive fiscal years, (iv) the Company’s surplus is less than its liquidation value at certain specified measurement dates, (v) occurrence of a merger, consolidation, or sale of greater than 50% of the Company’s assets, or (vi) the occurrence of liquidity events as set forth in the Stock Purchase Agreement. The redemption price is $ 20.00 per share plus dividends accrued but not paid. The Company is accreting the Series A Preferred Stock to redemption value over the period from the date of issuance to the date first callable by the Series A Preferred stockholders (September 27, 2031), such that the carrying amount of the security will equal the redemption amount at the earliest redemption date.

11. Stock-Based Compensation Plans

The components of stock-based compensation expense were as follows:
Three months ended September 30, Nine months ended September 30,
2025 2024 2025 2024
(in thousands)
2023 Incentive Stock Plan $ 11,253 $ 10,341 $ 34,821 $ 18,279
Employee Stock Purchase Plan 28 48 118 72
Total Stock Compensation Expense $ 11,281 $ 10,389 $ 34,939 $ 18,351

Under the 2023 Incentive Stock Plan (the “2023 Plan”), stock-based compensation is in the form of restricted stock awards (“RSAs”). The RSAs are subject to either service-based vesting, which is typically between one and four years , in which a specific period of continued employment must pass before an award vests, or performance-based vesting, which is typically between one and three years . The expense associated with these awards is recognized on a straight-line basis over the respective vesting period, with forfeitures accounted for as they occur. As it relates to performance-based awards, accrual of compensation expense is based on the probable outcome of the performance condition. For any vesting tranche of an award, the cumulative amount of compensation cost recognized is equal to the portion of the grant‑date fair value of the award tranche that is actually vested at that date.

As of September 30, 2025, the Company had granted 2,658,196 RSAs under the 2023 Plan and had 991,264 shares available for future issuance. The fair value of the RSAs equaled the stock price at the grant date.

The following table summarizes the restricted stock activity during the nine months ended September 30, 2025:
Shares
Balance of unvested shares as of December 31, 2024 569,425
Shares granted 603,509
Shares forfeited ( 9,653 )
Shares vested ( 331,398 )
Balance of unvested shares as of September 30, 2025 831,883

Under the Employee Stock Purchase Plan (“ESPP”), as amended and restated effective November 2021, 425,000 shares of common stock have been reserved for issuance. Eligible employees may designate no more than 10 % of their base cash compensation to be deducted each pay period for the purchase of common stock under the ESPP. Participants may purchase the lesser of 1,000 shares or $ 25,000 of common stock in any one calendar year. Each January 31 and July 31, shares of common stock are purchased with the employees’ payroll deductions from the immediately preceding six months at a price per share of 85 % of the lesser of the market price of the common stock on the purchase date or the market price of the common stock on the date of entry into an offering period. During the nine months ended September 30, 2025 and 2024, 3,194 and 9,843 shares of common stock, respectively, were issued under the ESPP. The Company issues new shares through its transfer agent upon an employee stock purchase.
12. Reportable Segments

The Company has two reportable segments: (i) Leasing and Related Operations, which involves acquiring and leasing, primarily pursuant to operating leases, commercial aircraft, aircraft engines, and other aircraft equipment, the selective purchase and resale of commercial aircraft engines and other aircraft equipment, and service and maintenance related businesses and (ii) Spare Parts Sales, which involves the purchase and resale of after-market engine parts, whole engines, engine modules, and portable aircraft components.

The Company’s Chief Operating Decision Maker (“CODM”) is Austin Willis, Chief Executive Officer. The CODM evaluates the performance and allocation of resources to each of the segments based on income or loss from operations. While the Company believes there are synergies between the two business segments, the segments are managed separately because each requires different business strategies.

Prior period segment information is presented on a comparable basis to the basis on which current period segment information is presented and reviewed by the CODM.

Overview

Our core business is acquiring and leasing commercial aircraft and aircraft engines and related aircraft equipment pursuant to operating leases, all of which we sometimes collectively refer to as “equipment.” As of September 30, 2025, the majority of our leases were operating leases, with the exception of certain failed sale-leaseback transactions classified as notes receivable under the guidance provided by Accounting Standards Codification (“ASC”) 842 and investments in sales-type leases. As of September 30, 2025, we had 69 lessees in 37 countries. Our portfolio is continually changing due to equipment acquisitions and sales.

Risks and Uncertainties

Given the uncertainty in the rapidly changing market and economic conditions related to the potential impact of changes in interest rates or inflation, as well as the impact of new or increased tariffs, we will continue to evaluate the nature and extent of the impact to the Company’s business and financial position. The ultimate extent of changes in interest rates or inflation, as well as the impact of new or increased tariffs, on the Company will depend on future developments, and such effects could exist for an extended period of time.

Lease Rent Revenue. Lease rent revenue consists of rental income from long-term and short-term engine leases, aircraft leases, and other leased parts and equipment. Lease rent revenue increased by $11.6 million, or 17.9%, to $76.6 million in the three months ended September 30, 2025 from $64.9 million for the three months ended September 30, 2024. The increase is due to an increase in the average size of the portfolio as compared to that of the prior year period as well as an increase in average utilization (based on net book value of equipment held for operating lease, maintenance rights, and notes receivable and investments in sales-type leases net of allowances) of equipment held in our operating lease portfolio.

At September 30, 2025, the Company had $2,700.4 million of equipment held in our operating lease portfolio, $144.8 million of notes receivable, $27.0 million of maintenance rights, and $16.3 million of investments in sales-type leases. At September 30, 2024, the Company had $2,435.6 million of equipment held in our operating lease portfolio, $175.4 million of notes receivable, $31.5 million of maintenance rights, and $23.2 million of investments in sales-type leases. Average utilization (based on net book value of equipment held for operating lease, maintenance rights, and notes receivable and investments in sales-type leases net of allowances) was approximately 86.0% and 82.9% for the three months ended September 30, 2025 and 2024, respectively.

Two customers accounted for approximately 12% and 10% of the Company’s total lease rent revenue during the three months ended September 30, 2025, and two customers each accounted for approximately 11% of the Company’s total lease rent revenue during the three months ended September 30, 2024.

Maintenance Reserve Revenue . Maintenance reserve revenue increased $26.3 million, or 52.8%, to $76.1 million for the three months ended September 30, 2025 from $49.8 million for the three months ended September 30, 2024. We recognized $29.5 million in long-term maintenance revenue for the three months ended September 30, 2025, compared to $1.2 million in long-term maintenance revenue recognized in the comparable prior period as more engines came off leases with long-term maintenance conditions. Long-term maintenance revenue is influenced by end of lease compensation and the realization of long-term maintenance reserves associated with engines coming off lease. Engines on lease with “non-reimbursable” usage fees generated $46.6 million of short-term maintenance revenues, compared to $48.5 million in the comparable prior period. Short-term maintenance revenues are a proxy for flight time of our portfolio of engines.

Spare Parts and Equipment Sales . Spare parts and equipment sales decreased by $5.5 million, or 50.3%, to $5.4 million for the three months ended September 30, 2025, compared to $10.9 million for the three months ended September 30, 2024. Spare parts sales were $5.4 million and $9.9 million for the three months ended September 30, 2025 and 2024, respectively, a decrease of $4.5 million, or 45.4%, compared to the same period in 2024. The decrease in spare parts sales reflects the variations in the timing of sales. There were no equipment sales for the three months ended September 30, 2025. Equipment sales for the three months ended September 30, 2024 were $1.0 million for the sale of one engine.

Interest Revenue. Interest revenue decreased slightly by $0.1 million, or 1.5%, for the three months ended September 30, 2025, as compared to that of the three months ended September 30, 2024.

31

Gain on Sale of Leased Equipment. During the three months ended September 30, 2025, we sold 10 engines, one airframe, and other parts and equipment from the lease portfolio for $73.7 million less economic closing adjustments, resulting in a net gain of $16.1 million. During the three months ended September 30, 2024, we sold 13 engines and other parts and equipment from the lease portfolio, resulting in a net gain of $9.5 million.

Maintenance Services Revenue . Maintenance services revenues predominately represent fleet management, engine and aircraft storage and repair services, and revenue related to fixed base operator services provided to third parties, such as refueling, maintenance, and hangar services. Maintenance services revenue decreased by $2.3 million, or 38.9%, to $3.6 million for the three months ended September 30, 2025, from $5.9 million for the three months ended September 30, 2024. The decrease primarily reflects a decrease in fleet management revenue resulting from the sale of that line of business on June 30, 2025 to our joint venture Willis Mitsui & Company Engine Support Limited (“WMES”).

Other Revenue. Other revenue increased by $0.4 million, or 24.4%, to $2.3 million for the three months ended September 30, 2025 from $1.8 million for the three months ended September 30, 2024. Other revenue consists primarily of managed service fee revenue related to the servicing of engines for the WMES lease portfolio. These services include management of the WMES lease portfolio, which occurs on an ongoing basis, as well as marketing, which occurs on a transactional basis.

Depreciation and Amortization Expense. Depreciation and amortization expense increased by $5.0 million, or 21.2%, to $28.7 million for the three months ended September 30, 2025, compared to $23.7 million for the three months ended September 30, 2024. The increase is primarily due to an increase in the size of our lease portfolio, the timing of placing acquired engines on lease, and to a lesser extent, an increase in accelerated depreciation on older engine models.

Cost of Spare Parts and Equipment Sales . Cost of spare parts and equipment sales decreased by $2.2 million, or 24.6%, to $6.7 million for the three months ended September 30, 2025, compared to $8.9 million for the three months ended September 30, 2024. Cost of spare parts sales were $6.7 million and $8.8 million for the three months ended September 30, 2025 and 2024, respectively, a decrease of $2.1 million, or 23.7%, reflecting the decrease in spare parts sales. Cost of equipment sales were $0.1 million for the three months ended September 30, 2024.

Cost of Maintenance Services. Cost of maintenance services predominately represent the costs of fleet management, engine and aircraft storage and repair services, and the management of fixed base operator services provided to third parties. Cost of maintenance services decreased by $1.3 million, or 19.8%, to $5.1 million for the three months ended September 30, 2025, compared to $6.4 million for the three months ended September 30, 2024, reflecting the decrease in maintenance services revenue.

Write-down of Equipment. There was $10.2 million in write-downs of equipment for the three months ended September 30, 2025, reflecting the write-down of eight engines. Write-downs were predominantly related to engines moved from Equipment held for operating lease to Equipment held for sale. There was $0.6 million in write-downs of equipment for the three months ended September 30, 2024, reflecting the write-down of three engines.

General and Administrative Expenses. General and administrative expenses increased by $9.2 million, or 22.9%, to $49.2 million for the three months ended September 30, 2025, compared to $40.0 million for the three months ended September 30, 2024. The increase reflects a $3.5 million increase in consultant fees, which was influenced by costs associated with the Company’s sustainable aviation fuel project, as well as a $1.6 million increase in legal fees primarily associated with finance and strategic initiatives. In addition, personnel costs increased by $2.8 million, which included an increase of $1.6 million in incentive compensation as a result of business performance to date as well as $0.9 million of additional share-based compensation.

Technical Expense. Technical expense consists of the non-capitalized cost of engine repairs, engine thrust rental fees, outsourced technical support services, sublease engine rental expense, engine storage and freight costs. Technical expense increased by $3.2 million to $8.4 million for the three months ended September 30, 2025, compared to $5.2 million for the three months ended September 30, 2024, primarily due to an increased level of engine repair activity as compared to that of the prior period.

32

Net Finance Costs. Net finance costs increased $9.3 million, or 33.5%, to $37.1 million for the three months ended September 30, 2025, compared to $27.8 million for the three months ended September 30, 2024, primarily due to an overall increased level of debt obligations. There was additional interest expense of $8.3 million for the three months ended September 30, 2025 associated with the Willis Engine Structured Trust VIII (“WEST VIII”) notes payable, which closed in June 2025, and loss on debt extinguishment of $3.0 million associated with the refinance of Willis Engine Structured Trust IV (“WEST IV”) and Willis Engine Structured Trust VII (“WEST VII”) notes. Additionally, derivative-related receipts were $(0.5) million for the three months ended September 30, 2025, as compared to $3.0 million for the three months ended September 30, 2024, as certain interest rate swap positions were terminated. These increases in expense were partially offset by an increase of $3.0 million in interest income primarily related to interest earned on WEST VIII restricted cash accounts.

Income Tax Expense. Income tax expense was $18.9 million for the three months ended September 30, 2025, compared to income tax expense of $10.4 million for the three months ended September 30, 2024. The effective tax rate for the third quarter of 2025 was 43.7%, compared to 30.1% in the prior year period. The Company’s effective tax rate differed from the U.S. federal statutory rate of 21.0% primarily due to executive compensation exceeding $1.0 million as defined in Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”). H.R. 1., also known as the One Big Beautiful Bill Act (“OBBBA”), was enacted on July 4, 2025. The provisions of the OBBBA impacted certain tax deductions, including bonus depreciation, limiting the Company’s ability to benefit from the Section 250 deduction. This disallowance caused the Company’s third quarter effective tax rate to be higher than that of the previous quarter.

Other revenue 7,693 6,841 12.5 %
Total revenue $ 536,623 $ 416,426 28.9 %
Lease Rent Revenue. Lease rent revenue increased by $42.9 million, or 24.7%, to $216.6 million for the nine months ended September 30, 2025, compared to $173.7 million for the nine months ended September 30, 2024. The increase is due to an increase in the average size of the portfolio as compared to that of the prior year period as well as an increase in average utilization (based on net book value of equipment held for operating lease, maintenance rights, and notes receivable and investments in sales-type leases net of allowances) of equipment held in our operating lease portfolio.
At September 30, 2025, the Company had $2,700.4 million of equipment held in our operating lease portfolio, $144.8 million of notes receivable, $27.0 million of maintenance rights, and $16.3 million of investments in sales-type leases. At September 30, 2024, the Company had $2,435.6 million of equipment held in our operating lease portfolio, $175.4 million of notes receivable, $31.5 million of maintenance rights, and $23.2 million of investments in sales-type leases. Average utilization (based on net book value of equipment held for operating lease, maintenance rights, and notes receivable and investments in sales-type leases net of allowances) was approximately 84.4% and 83.3% for the nine months ended September 30, 2025 and 2024, respectively.
Two customers accounted for approximately 13% and 10% of the Company’s total lease rent revenue during the nine months ended September 30, 2025, and two customers accounted for approximately 11% and 10% of the Company’s total lease rent revenue during the nine months ended September 30, 2024.

33

Maintenance Reserve Revenue. Maintenance reserve revenue increased $25.1 million, or 16.1%, to $181.7 million for the nine months ended September 30, 2025 from $156.5 million for the nine months ended September 30, 2024. Long-term maintenance revenue was $39.5 million for the nine months ended September 30, 2025 compared to $24.6 million in the prior year period, an increase of $15.0 million or 61.0%. Long-term maintenance revenue is influenced by end of lease compensation and the realization of long-term maintenance reserves associated with engines coming off lease. Engines on lease with “non-reimbursable” usage fees generated $142.1 million of short-term maintenance revenues compared to $132.0 million in the comparable prior period, an increase of $10.1 million or 7.7%. The increase in short-term maintenance reserve revenue was influenced by an increase in the number of engines on short-term lease conditions, and the systematic, contractual increase in the hourly and cyclical usage rates on our engines.
Spare Parts and Equipment Sales. Spare parts and equipment sales increased by $33.7 million, or 165.5%, to $54.0 million for the nine months ended September 30, 2025 compared to $20.3 million in the prior year period. Spare parts sales were $30.7 million and $19.4 million for the nine months ended September 30, 2025 and 2024, respectively, an increase of $11.3 million, or 58.4%, compared to the same period in 2024. The increase in spare parts sales for the nine months ended September 30, 2025 reflects the demand for surplus material as operators extend the lives of their current generation engine portfolios. Equipment sales for the nine months ended were $23.3 million for the sale of two engines. Equipment sales for the nine months ended September 30, 2024 were $1.0 million for the sale of one engine.

Interest Revenue. Interest revenue increased by $3.0 million, or 37.4%, to $10.9 million for the nine months ended September 30, 2025 compared to $8.0 million for the nine months ended September 30, 2024. The increase primarily reflects an overall higher amount of interest revenue recognized on new notes receivable that were entered into during the latter half of 2024. Notes receivable result from failed sale-leasebacks in which the Company was the buyer-lessor.

Gain on Sale of Leased Equipment. During the nine months ended September 30, 2025, we sold 31 engines, four airframes, and other parts and equipment from the lease portfolio for $212.5 million less economic closing adjustments, resulting in a net gain of $48.2 million. During the nine months ended September 30, 2024, we sold 28 engines, eight airframes, and other parts and equipment from the lease portfolio, resulting in a net gain of $33.1 million.

Gain on Sale of Financial Assets. During the nine months ended September 30, 2025, we sold two investments in sales-type lease assets for a net gain of $0.4 million. There was no gain on sale of financial assets during the nine months ended September 30, 2024.

Maintenance Services Revenue . Maintenance services revenue decreased by $0.7 million, or 3.9%, to $17.3 million for the nine months ended September 30, 2025, from $18.0 million for the nine months ended September 30, 2024, reflecting the sale of the fleet management business on June 30, 2025 to our joint venture WMES.

Other Revenue. Other revenue increased by $0.9 million, or 12.5%, to $7.7 million for the nine months ended September 30, 2025 from $6.8 million for the nine months ended September 30, 2024. Other revenue consists primarily of managed service fee revenue related to the servicing of engines for the WMES lease portfolio. These services include management of the WMES lease portfolio, which occurs on an ongoing basis, as well as marketing, which occurs on a transactional basis.

Depreciation and Amortization Expense. Depreciation and amortization expense increased by $12.9 million, or 18.9%, to $81.2 million for the nine months ended September 30, 2025 compared to $68.3 million for the nine months ended September 30, 2024. The increase is primarily due to an increase in the size of our lease portfolio, the timing of placing acquired engines on lease, and to a lesser extent, an increase in accelerated depreciation on older engine models.
Cost of Spare Parts and Equipment Sales. Cost of spare parts and equipment sales increased by $33.1 million, or 194.7%, to $50.1 million for the nine months ended September 30, 2025 compared to $17.0 million for the nine months ended September 30, 2024. Cost of spare parts sales were $28.8 million and $16.9 million for the nine months ended September 30, 2025 and 2024, respectively, an increase of $11.9 million, or 70.6%, reflecting the increase in spare parts sales. Cost of equipment sales were $21.3 million and $0.1 million for the nine months ended September 30, 2025 and September 30, 2024, respectively, reflecting the increase in equipment sales.
Cost of Maintenance Services. Cost of maintenance services increased by $1.4 million, or 8.1%, to $19.1 million for the nine months ended September 30, 2025, compared to $17.6 million for the nine months ended September 30, 2024. The increase is primarily related to an increase in personnel costs, as a result of expansion of our aircraft tear down and repair services business.

Write-down of Equipment. Write-down of equipment was $23.8 million for the nine months ended September 30, 2025, primarily reflecting the write-down of 19 engines. Write-downs were predominantly related to engines moved from Equipment held for operating lease to Equipment held for sale. Write-down of equipment was $0.9 million for the nine months ended September 30, 2024, primarily reflecting the write-down of one airframe and three engines.
34

General and Administrative Expenses. General and administrative expenses increased by $43.0 million, or 41.3%, to $147.3 million for the nine months ended September 30, 2025 compared to $104.3 million for the nine months ended September 30, 2024. The increase primarily reflects a $22.1 million increase in personnel costs, which included an increase of $16.5 million in share-based compensation and an increase of $3.3 million in wages. Of the $16.5 million increase in share-based compensation, $5.3 million related to the acceleration of the vesting of shares upon the resignation of our prior General Counsel, and the remainder primarily related to the appreciation of the market value of the Company’s equity as well as share awards to new personnel to support the continued growth of the Company. Further, there was a $9.8 million increase in consultant fees, which was influenced by costs associated with the Company’s sustainable aviation fuel project, as well as a $4.9 million increase in legal fees primarily associated with finance and strategic initiatives.
Technical Expense. Technical expense increased by $4.2 million, or 23.2%, to $22.1 million for the nine months ended September 30, 2025 compared to $17.9 million for the nine months ended September 30, 2024, primarily due to an increased level of engine repair activity as compared to that of the prior period.
Net Finance Costs. Net finance costs increased by $27.4 million, or 36.4%, to $102.8 million for the nine months ended September 30, 2025 compared to $75.4 million for the nine months ended September 30, 2024, primarily due to an overall increased level of debt obligations. Interest expense associated with the Company’s credit facility increased by $9.4 million for the nine months ended September 30, 2025, due to an increase in the average outstanding balance of the credit facility for the nine months ended September 30, 2025, as compared to that of the prior year period. Further, there was additional interest expense of $7.2 million for the nine months ended September 30, 2025 associated with Willis Warehouse Facility LLC (“WWFL”), as the senior secured warehouse facility did not close until May 2024, and $9.6 million of additional interest expense associated with WEST VIII notes payable, which did not close until June 2025, and loss on debt extinguishment of $3.0 million. These increases in interest expense were partially offset by a decrease of $3.8 million in interest expense associated with WEST VII notes payable due to a reduction in these notes outstanding and $1.9 million of increased interest income associated with larger restricted cash balances as we refinanced the balance sheet. Additionally, derivative-related receipts were $4.4 million for the nine months ended September 30, 2025, as compared to $9.2 million for the nine months ended September 30, 2024 as certain interest rate swap positions were terminated and certain interest rate metrics fluctuated.

Gain on Sale of Business. During the nine months ended September 30, 2025, a wholly-owned subsidiary of the Company, entered into a Share Purchase Agreement (the “SPA”), by and between Willis Asset Management Limited (“WAML”) and WMES. Pursuant to the SPA, WAML sold the entire issued share capital of Bridgend Asset Management Limited (“BAML”), a United Kingdom-based aviation consultancy business, to WMES for a total purchase price of $45.0 million subject to certain working capital adjustments. The transaction closed on June 30, 2025, resulting in a gain on sale of business of approximately $43.0 million for the Company.

Income Tax Expense. Income tax expense was $41.2 million for the nine months ended September 30, 2025 compared to $34.7 million for the nine months ended September 30, 2024. The effective tax rate for the nine months ended September 30, 2025 was 28.9% compared to 28.4% in the prior year period. The Company’s effective tax rate differed from the U.S. federal statutory rate of 21.0% primarily due to executive compensation exceeding $1.0 million as defined in Section 162(m) of the Code, as well as the sale of the Company’s entire issued share capital of BAML, a discrete item per ASC 270, “Interim Reporting,” due to the unusual and infrequent nature of the sale. The provisions of the OBBBA impacted certain tax deductions, including bonus depreciation, limiting the Company’s ability to benefit from the Section 250 deduction.
Financial Position, Liquidity and Capital Resources
Liquidity
At September 30, 2025, the Company had $12.9 million of cash and cash equivalents and $158.1 million of restricted cash. We fund our operations primarily from cash provided by our leasing activities. We finance our growth through borrowings secured primarily by our equipment lease portfolio. Cash of approximately $1,005.1 million and $518.9 million for the nine months ended September 30, 2025 and 2024, respectively, was derived from our borrowing activities, which included our $596.0 WEST VIII capital raise in June 2025. In these same time periods, $1,029.8 million and $331.2 million, respectively, was used to pay down related debt.

For any interest rate swaps that we enter into, we will be exposed to risk in the event of non-performance of the interest rate hedge counter-parties. We may hedge additional amounts of our floating rate debt in the future.

Cash Flows Discussion
35


Cash flows provided by operating activities were $209.1 million and $216.4 million for the nine months ended September 30, 2025 and 2024, respectively. The $7.4 million, or 3.4%, decrease in operating cash flows was primarily driven by a $23.2 million decrease in payments on sales-type leases, a period over period $28.1 million decrease in cash flows from changes in accounts receivable, and a period over period $24.0 million decrease in cash flows from changes in accounts payable and accrued expenses. Partially offsetting the decreases was a period over period $52.1 million increase in cash flows from changes in inventory. These changes reflect significant inventory purchases made in the prior comparable period to meet the high demand for spare parts. Spare parts sales were $30.7 million and $19.4 million for the nine months ended September 30, 2025 and 2024, respectively, an increase of $11.3 million, or 58.4%, compared to the same period in 2024. Cash flows from operations are driven significantly by payments made under our lease agreements, which comprise lease revenue, security deposits and maintenance reserves, and are offset by interest expense and general and administrative costs. Cash received as maintenance reserve payments for some of our engines on lease are partially restricted by our debt arrangements. The lease revenue stream, in the short term, is at fixed rates while a portion of our debt is at variable rates. If interest rates increase, it is unlikely we could increase lease rates in the short term, and this would cause a reduction in our earnings and operating cash flows. Revenue and maintenance reserves are also affected by the amount of equipment off lease. The average utilization rate (based on net book value of equipment held for operating lease, maintenance rights, and notes receivable and investments in sales-type leases net of allowances) for the nine months ended September 30, 2025 and 2024 was approximately 84.4% and 83.3%, respectively. If there is an increase in off-lease rates or deterioration in lease rates that are not offset by reductions in interest rates, there will be a negative impact on earnings and cash flows from operations.

Cash flows used in investing activities were $108.2 million for the nine months ended September 30, 2025 and primarily reflected $310.6 million for the purchase of equipment held for operating lease and for sale (including capitalized costs and prepaid deposits made in the period) and $23.2 million for the purchase of property, equipment and furnishings, which was primarily related to leasehold improvements, partially offset by proceeds from sale of equipment (net of selling expenses) of $194.3 million and proceeds from sale of business of $21.9 million. Cash flows used in investing activities were $455.0 million for the nine months ended September 30, 2024 and primarily reflected $488.4 million for the purchase of equipment held for operating lease (including capitalized costs and prepaid deposits made in the period) and $89.6 million related to leases entered into which were classified as notes receivable under ASC 842, partly offset by proceeds from sale of equipment (net of selling expenses) of $117.9 million.
Cash flows used in financing activities were $62.4 million for the nine months ended September 30, 2025 and primarily reflected $1,029.8 million in principal payments and $18.7 million in cancellation of restricted stock in satisfaction of withholding tax, partially offset by $1,005.1 million in proceeds from debt obligations. Cash flows provided by financing activities were $175.6 million for the nine months ended September 30, 2024 and primarily reflected $518.9 million in proceeds from debt obligations and $13.1 million in proceeds from issuance of preferred stock, partially offset by $331.2 million in principal payments, $8.9 million in cash dividends paid to shareholders of common stock, and $7.2 million in cancellation of restricted stock in satisfaction of withholding tax.
Cash Dividends
During the nine months ended September 30, 2025 and September 30, 2024, the Company paid cash dividends of $5.7 million and $8.9 million, respectively, to shareholders of common stock.
Preferred Stock Dividends
In September 2024, the Company entered into a Series A Preferred Stock Purchase Agreement with Development Bank of Japan Inc. (the “Stock Purchase Agreement”), which refinanced and expanded the Company’s Series A-1 and Series A-2 Preferred Stock into one $65.0 million Series A Preferred Stock series (the “Series A Preferred Stock”), which accrues quarterly dividends at the rate per annum of 8.35% per share.
Prior to the Stock Purchase Agreement, the Company’s Series A-1 Preferred Stock accrued quarterly dividends at the rate per annum of 8.5% per share, and the Series A-2 Preferred Stock accrued quarterly dividends at the rate per annum of 6.5% per share. During each of the nine months ended September 30, 2025 and 2024, the Company paid total preferred stock dividends of $4.3 million and $3.4 million, respectively.
Debt Obligations and Covenant Compliance
At September 30, 2025, debt obligations consisted of loans totaling $2,239.5 million, net of unamortized issuance costs and note discounts, payable with interest rates varying between approximately 3.1% and 8.0%. Substantially all of our assets are pledged to secure our obligations to creditors. For further information on our debt instruments, see Note 4 “Debt Obligations” in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Virtually all of our debt requires our ongoing compliance with certain financial covenants including debt/equity ratios, minimum tangible net worth and minimum interest coverage ratios, and other eligibility criteria including customer and geographic concentration restrictions. Under our revolving credit facility, we can borrow no more than 85% of an engine’s net book value and 65% of the net book value of an airframe, spare parts or other assets. Therefore, we must have other available funds for the balance of the purchase price of any new equipment to be purchased. Our revolving credit facility, certain indentures and other debt related agreements also contain cross-default provisions. If we do not comply with the covenants or eligibility requirements, we may not be permitted to borrow additional funds and accelerated payments may become necessary. Additionally, much of the debt is secured by engines and aircraft, and to the extent that engines or aircraft are sold, repayment of that portion of the debt could be required.

At September 30, 2025, we were in compliance with the covenants specified in our revolving credit facility, including the Interest Coverage Ratio requirement of at least 2.25 to 1.00, and the Total Leverage Ratio requirement of not greater than 4.00 to 1.00. The Interest Coverage Ratio, as defined in the credit facility, is the ratio of earnings before interest, taxes, depreciation and amortization and other one-time charges to consolidated interest expense. The Total Leverage Ratio, as defined in the credit facility, is the ratio of total indebtedness to tangible net worth. At September 30, 2025, we were in compliance with the covenants specified in the WEST III, WEST IV, WEST V, WEST VI, WEST VII, WEST VIII, and WWFL indentures and servicing and other debt related agreements.

Off-Balance Sheet Arrangements

As of September 30, 2025, we had no material off-balance sheet arrangements or obligations that have or are reasonably likely to have a current or future effect on our financial condition, change in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures, or capital resources that are material to investors.

Contractual Obligations and Commitments

Repayments of our gross debt obligations primarily consist of scheduled installments due under term loans and are funded by the use of unrestricted cash reserves and from cash flows from ongoing operations. The table below summarizes our contractual commitments at September 30, 2025:

Payment due by period (in thousands)
Total Less than
1 Year
1-3 Years 3-5 Years More than
5 Years
Debt obligations $ 2,267,951 $ 120,769 $ 462,064 $ 1,065,103 $ 620,015
Interest payments under debt obligations 394,407 99,918 179,200 98,522 16,767
Purchase obligations 1,040,692 235,689 395,485 303,286 106,232
Operating lease obligations 17,662 3,771 5,259 2,691 5,941
Total $ 3,720,712 $ 460,147 $ 1,042,008 $ 1,469,602 $ 748,955

From time to time we enter into contractual commitments to purchase engines directly from original equipment manufacturers. We are currently committed to purchasing 30 additional new LEAP-1A engines and 21 additional new LEAP-1B engines for an aggregate total of $912.6 million by 2030. Further, we are currently committed to purchasing five engines for approximately $22.6 million in 2025 and six engines for $105.5 million in 2026. The purchase obligations are subject to escalation based on the closing date of each transaction. Our purchase agreements generally contain terms that allow the Company to defer or cancel purchase commitments in certain situations. These deferrals or conversions would not result in penalties or increased costs other than any potential increase due to the normal year-over-year change in engine list prices, which is akin to ordinary inflation.

In December 2020, we entered into definitive agreements for the purchase of 25 Pratt & Whitney aircraft engines. As part of the purchase, we have committed to certain future overhaul and maintenance services which are anticipated to range between $97.1 million and $126.8 million by 2030.

We have estimated the interest payments due under debt obligations by applying the interest rates applicable at September 30, 2025 to the remaining debt, adjusted for the estimated debt repayments identified in the table above. Actual interest payments made will vary due to changes in the rates.

37

We believe our equity base, internally generated funds and existing debt facilities are sufficient to maintain our level of operations for the next twelve months. The level of internally generated funds could decline if the amount of equipment off-lease increases, there is a decrease in availability under our existing debt facilities, or there is a significant increase in borrowing costs. Such decline would impair our ability to sustain our current level of operations. We continue to discuss additions to our capital base with our commercial and investment banks. If we are not able to access additional capital, our ability to continue to grow our asset base consistent with historical trends will be impaired and our future growth would be limited to that which can be funded from internally generated capital.

Recent Accounting Pronouncements

The most recent adopted accounting pronouncements and accounting pronouncements to be adopted by the Company are described in Note 1 to our Unaudited Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
Our primary market risk exposure is that of interest rate risk. A change in interest rates would affect our cost of borrowing. Increases in interest rates, which may cause us to raise the implicit rates charged to our customers, could result in a reduction in demand for our leases. Alternatively, we may price our leases based on market rates so as to keep the fleet on-lease and suffer a decrease in our operating margin due to interest costs that we are unable to pass on to our customers. As of September 30, 2025, $581.8 million of our outstanding debt is variable rate debt. We estimate that for every one percent increase or decrease in interest rates on our variable rate debt, net of our interest rate swaps, our annual interest expense would increase or decrease by $2.5 million.
We hedge a portion of our borrowings from time to time, effectively fixing the rate of these borrowings. This hedging activity, which at times is required by our borrowing facilities, helps protect us against reduced margins on longer term fixed rate leases. Such hedging activities may limit our ability to participate in the benefits of any decrease in interest rates but may also protect us from increases in interest rates. Furthermore, since lease rates tend to vary with interest rate levels, it is possible that we can adjust lease rates for the effect of changes in interest rates at the termination of leases. Other financial assets and liabilities are at fixed rates.
We are also exposed to currency devaluation risk. Substantially all of our leases require payment in U.S. dollars. During the nine months ended September 30, 2025 and 2024, 70% and 70%, respectively, of our lease rent revenues came from non-United States domiciled lessees. If these lessees’ currency devalues against the U.S. dollar, the lessees could potentially encounter difficulty in making their lease payments.
Item 4. Controls and Procedures

(a) Evaluation of disclosure controls and procedures. In accordance with Rule 13a-15(b) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness and design of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange Act), as of the end of the period covered by this report. Based on such evaluation, our CEO and CFO have concluded that as of September 30, 2025, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

(b) Inherent limitations on controls. Management, including the CEO and CFO, does not expect that our disclosure controls and procedures will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs.

(c) Changes in internal control over financial reporting. There has been no change in our internal control over financial reporting during our fiscal quarter ended September 30, 2025 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

Item 1A. Risk Factors

Investors should carefully consider the risks in the “Risk Factors” in Part 1: Item 1A of our 2024 Form 10-K, filed with the SEC on March 11, 2025, and our other filings with the SEC. These risks are not the only ones facing the Company. Additional risks not currently known to us or that we currently believe are immaterial may also impair our business operations. Any of these risks could adversely affect our business, cash flows, financial condition and results of operations. The trading price of our common stock could fluctuate due to any of these risks, and investors may lose all or part of their investment. In assessing these risks, investors should also refer to the other information contained or incorporated by reference in this Quarterly Report on Form 10-Q. Other than as set forth below, there have been no material changes in our risk factors from those discussed in our 2024 Form 10-K.

The Company’s business may be materially adversely affected by the imposition of duties and tariffs and other trade barriers and retaliatory countermeasures implemented by the U.S. and other governments.

Recently there have been significant changes to U.S. trade policies, sanctions, legislation, treaties and tariffs, including, but not limited to, trade policies and tariffs affecting products from outside of the U.S. The extent and duration of increased tariffs and the resulting impact on general economic conditions and on our business are uncertain and depend on various factors, such as negotiations between the U.S. and affected countries, the responses of other countries or regions, exemptions or exclusions that may be granted, availability and cost of alternative sources of supply, and demand for our business in affected markets. Additionally, it is possible that U.S. policy changes and uncertainty about such changes could increase market volatility and currency exchange rate fluctuations. As a result of these dynamics, we cannot predict the impact to our business of any future changes to the U.S.’s or other countries’ trading relationships or the impact of new laws or regulations adopted by the U.S. or other countries.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

(a) None.

(b) None.

(c) Issuer Purchases of Equity Securities. In December 2024, the Board of Directors approved the renewal of the existing common stock repurchase plan which allows for repurchases of up to $60.0 million of the Company’s common stock, extending the plan through December 31, 2026. Repurchased shares are immediately retired. No shares were repurchased during the nine months ended September 30, 2025. Share repurchase activity during the three months ended September 30, 2025 was as follows (in thousands):

Period (a) Total Number of Shares Purchased (b) Average Price Paid per Share (c) Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs d) Approximate Dollar Value of Shares that May Yet be Purchased under the Plans of Programs
July 1, 2025 through July 31, 2025 $ 39,595
August 1, 2025 through August 31, 2025 $ 39,595
September 1, 2025 through September 30, 2025 $ 39,595
Total $ 39,595

Item 3. Defaults Upon Senior Securities

None.

Item 4. Mine Safety Disclosures
