The Company uses the equity method of accounting for investments in entities in which it exercises significant influence, but which does not meet the requirements for consolidation. Under the equity method, the Company records its proportionate share of the underlying net income (loss) of these entities.

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

Restructuring Charges—The termination of the Management Agreement in 2024 was a material change in the management structure of the business and is accounted for under ASC 420, Exit or Disposal Cost Obligations. The termination fee payment to the Former Manager under the Internalization Agreement is recorded within Internalization Fee to Affiliate. See Note 16 for additional discussion of the restructuring charges related to the Internalization.

Risks and Uncertainties—In the normal course of business, the Company encounters several significant types of economic risk including credit, market, and capital market risks. Credit risk is the risk of the inability or unwillingness of a lessee or customer to make contractually required payments or to fulfill its other contractual obligations. Market risk reflects the risk of a downturn or volatility in the underlying industry segments in which the Company operates, which could adversely impact the pricing of the services offered by the Company or a lessee’s or customer’s ability to make payments, increase the risk of unscheduled lease terminations and depress lease rates and the value of the Company’s leasing equipment or operating assets. Capital market risk is the risk that the Company is unable to obtain capital at reasonable rates to fund the growth of its business or to refinance existing debt facilities. The Company, through its subsidiaries, also conducts operations outside of the United States; such international operations are subject to the same risks as those associated with the Company’s United States operations as well as additional risks, including unexpected changes in regulatory requirements, heightened risk of political and economic instability, potentially adverse tax consequences and the burden of complying with foreign laws. The Company does not have significant exposure to foreign currency risk as all of its leasing arrangements are denominated in U.S. dollars.

Inventory, net—The Company holds aircraft engines, engine modules, spare parts and used material inventory for sale. At times, inventory is transferred to leasing equipment in connection with a rebuilt engine or engine repair. Inventory is carried at the lower of cost or net realizable value on the Company’s Consolidated Balance Sheets.

Property, Plant and Equipment, Leasing Equipment and Depreciation—Property, plant and equipment and leasing equipment are stated at cost (inclusive of capitalized acquisition costs, where applicable) and depreciated using the straight-line method, over its estimated useful lives, to estimated residual values which are summarized as follows:

Asset

Range of Estimated Useful Lives

Residual Value Estimates

Aircraft

25 years from date of manufacture

Generally not to exceed 15% of manufacturer’s list price when new

Aircraft engines

Major improvements and modifications incurred in connection with the acquisition of property, plant and equipment and leasing equipment that are required to get the asset ready for initial service are capitalized and depreciated over the remaining life of the asset. Project costs of major additions and betterments, including capitalizable engineering costs and other costs directly related to the development or construction of a project, are capitalized and depreciation commences once it is placed into service for leasing equipment and once it is ready for service for property, plant and equipment. Interest costs directly related to and incurred during the construction period of property, plant and equipment are capitalized.

For planned major maintenance or component overhaul activities for aviation equipment off lease, the cost of such major maintenance or component overhaul event is capitalized and depreciated on a straight-line basis over the period until the next maintenance or component overhaul event is required. Major maintenance and overhauls of the Company’s maintenance repair facilities and related equipment that extend the life of the asset are capitalized and depreciated over the expected period until the next anticipated major maintenance or overhaul.

In accounting for leasing equipment, the Company makes estimates about the expected useful lives, residual values and the fair value of acquired in-place leases and acquired maintenance liabilities (for aviation equipment). In making these estimates, the Company relies upon observable market data for the same or similar types of equipment and, in the case of aviation equipment, its own estimates with respect to a lessee’s anticipated utilization of the aircraft or engine. When the Company acquires leasing equipment subject to an in-place lease, determining the fair value of the in-place lease requires the Company to make assumptions regarding the current fair values of leases for identical or similar equipment, in order to determine if the in-place lease is within a fair value range of current lease rates. If a lease is below or above the range of current lease rates, the resulting lease discount or premium is recognized as a lease intangible and amortized into lease income over the remaining term of the lease.

Capitalized Interest—The interest cost associated with major development and construction projects are capitalized and included in the cost of the project. Interest capitalization ceases once a project is substantially complete or no longer undergoing construction activities to prepare it for its intended use. The Company capitalized interest of $0.0 million, $0.2 million and $0.7 million during the years ended December 31, 2025, 2024 and 2023, respectively.

Repairs and Maintenance—Repair and maintenance costs that do not extend the lives of the assets are expensed as incurred. The Company's repairs and maintenance expense was $3.2 million, $9.8 million and $7.7 million during the years ended December 31, 2025, 2024 and 2023, respectively, and are included in Operating expenses.

Impairment of Long-Lived Assets—The Company performs a recoverability assessment of each of its long-lived assets whenever events or changes in circumstances, or indicators, indicate that the carrying amount or net book value of an asset may not be recoverable. Indicators may include, but are not limited to, a significant lease restructuring or early lease termination; significant traffic decline; a significant change in market conditions; the introduction of newer technology and the length of time an asset is off lease related to leasing equipment, engines or for manufacturing equipment; a significant decrease in market value; adverse changes in use or condition; legal or regulatory changes; or cash flow reductions.

If a quantitative recoverability assessment is determined to be needed, the Company measures whether the estimated future undiscounted net cash flows expected to be generated by the asset exceeds its net book value. The undiscounted cash flows consist of cash flows of the asset or asset group. For long lived assets, the undiscounted cash flows consist of cash flows from currently contracted leases and contracts, future projected leases, transition costs, estimated down time and estimated residual or scrap values for leasing equipment or operating cash flows for manufacturing equipment, and maintenance and operating costs. In the event that an asset does not meet the recoverability test, the carrying value of the asset will be adjusted to fair value resulting in an impairment charge.

Management develops the assumptions used in the recoverability analysis based on its knowledge of active contracts, current and future expectations of the global demand for a particular asset and historical experience in the leasing markets, information received from third party industry sources, usage assumptions, asset lifespan for leasing equipment, and expected operating income and costs associated with operating and maintaining the manufacturing asset. The factors considered in estimating the undiscounted cash flows are impacted by changes in future periods due to changes in contracted lease rates, residual values, economic conditions, technology, demand for a particular asset type and other factors, expected income and operating costs, maintenance and repairs, capital expenditures, and duration of the cash flows.

The Company assesses the recoverability of goodwill using a qualitative evaluation or a quantitative test to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. The determination of fair value requires management to make assumptions and to apply judgment to estimate industry and economic factors and the profitability of future business strategies. The Company conducts impairment testing based on current business strategy in light of present industry and economic conditions, as well as future expectations.

Maintenance Payments—Typically, under an operating lease of aircraft, the lessee is responsible for performing all maintenance and is generally required to make maintenance payments to the Company for heavy maintenance, overhaul or replacement of certain high-value components of the aircraft or engine. These maintenance payments are based on hours or cycles of utilization or on calendar time, depending on the component, and are generally required to be made monthly in arrears. If a lessee is making monthly maintenance payments, the Company would typically be obligated to reimburse the lessee for costs they incur for heavy maintenance, overhaul or replacement of certain high-value components to the extent of maintenance payments received in respect of the specific maintenance event, usually shortly following the completion of the relevant work.

The Company records the portion of maintenance payments paid by the lessee that are expected to be reimbursed as maintenance deposit liabilities in the Consolidated Balance Sheets. Reimbursements made to the lessee upon the receipt of evidence of qualifying maintenance work are recorded against the maintenance deposit liability. In certain leases, the Company or the lessee may be obligated to make a payment to the other party at lease termination based on redelivery conditions stipulated at the inception of the lease. When the lessee is required to return the aircraft in an improved maintenance condition, the Company records a maintenance right asset, as a component of other assets, for the estimated value of the end-of-life maintenance payment at acquisition. The Company recognizes payments received as end-of-lease compensation adjustments, within lease income or as a reduction to the maintenance right asset, when payment is received or collectability is assured. In the event the Company is required to make payments at the end of the lease for redelivery conditions, amounts are accrued as additional maintenance liability and expensed when the Company is obligated and can reasonably estimate such payments.

Lease Incentives and Amortization—Lease incentives, which include lease acquisition costs related to reconfiguration of the aircraft cabin, other lessee specific modifications and other direct costs, are capitalized and amortized as a reduction of lease income over the primary term of the lease, assuming no lease renewals.

In accounting for acquired leasing equipment, the Company makes estimates about the fair value of the acquired leases. In determining the fair value of these leases, the Company makes assumptions regarding the current fair values of leases for identical or similar equipment in order to determine if the acquired lease is within a fair value range of current lease rates. If a lease is below or above the range of current lease rates, the resulting lease discount or premium is recognized as a lease intangible and amortized into lease income over the remaining term of the lease. Acquired lease intangibles are amortized on a straight-line basis over the remaining lease terms, which collectively had a weighted-average remaining amortization period of 7.7 years as of December 31, 2025, and are recorded as a component of revenues.

Deferred Financing Costs—Costs incurred in connection with obtaining long term financing are capitalized and amortized to interest expense over the term of the underlying loans. Unamortized deferred financing costs of $47.4 million and $55.5 million as of December 31, 2025 and 2024, respectively, are included in Long-term debt, net.

Aerospace products revenue—Aerospace products revenue primarily consists of the transaction price related to the sale of CFM56-7B, CFM56-5B and V2500 engines, engine modules, spare parts and used material inventory, and are accounted for within the scope of ASC 606. Revenue is recognized at the point in time when a performance obligation is satisfied by transferring control over the related asset to a customer along with corresponding costs of sales. Aerospace products revenue also consists of engine management service contracts, where the Company has a stand-ready obligation to provide replacement CFM56-7B and CFM56-5B engines to customers as they become unserviceable during the contract term. The Company recognizes revenue related to these engine management service contracts over time using a straight-line attribution method and the costs related to fulfilling the performance obligation are expensed as incurred.

Maintenance, Repair and Exchange (“MRE”) Contract revenue—MRE Contract revenue consists of the transaction price related to the sale of CFM56-5B, CFM56-7B and V2500 commercial aircraft engines and related modules to, and subsequent exchange of unserviceable engines and modules from, the special purpose entities (the “SPVs”) of the first partnership of the strategic capital initiative (the “2025 Partnership”). MRE Contract revenue is recognized under ASC 606 at the point in time when a performance obligation is satisfied by transferring control of the serviceable engine or module to the 2025 Partnership, along with corresponding costs of sales. Refer to Note 12 “Affiliate Transactions and Former Management Agreement” for additional information on the 2025 Partnership and the strategic capital initiative.

Operating Leases—The Company leases equipment pursuant to operating leases. Operating leases with fixed rentals and step rentals are recognized on a straight-line basis over the term of the lease, assuming no renewals. Revenue is not recognized when collection is not reasonably assured. When collectability is not reasonably assured, the lessee is placed on non-accrual status and revenue is recognized when cash payments are received.

Generally, under the Company’s aircraft lease and engine agreements, the lessee is required to make periodic maintenance payments calculated based on the lessee’s utilization of the leased asset or at the end of the lease. Typically, under the Company’s aircraft lease agreements, the lessee is responsible for maintenance, repairs and other operating expenses throughout the term of the lease. These periodic maintenance payments accumulate over the term of the lease to fund major maintenance events, and the Company is contractually obligated to return maintenance payments to the lessee up to the cost of maintenance events paid by the lessee. In the event the total cost of maintenance events over the term of a lease is less than the cumulative maintenance payments, the Company is not required to return any unused maintenance payments to the lessee.

Maintenance payments received for which the Company expects to repay to the lessee are presented as current and non-current Maintenance deposits in its Consolidated Balance Sheets. Excess maintenance payments received that the Company does not expect to repay to the lessee are recorded as Maintenance revenue on its Consolidated Statements of Operations. Estimates in recognizing revenue include mean time between removal for engines on leased aircraft, projected costs for engine maintenance, and forecasted utilization, which are affected by historical usage patterns and overall industry, market and economic conditions. Significant changes to these estimates could have a material effect on the amount of revenue recognized in the period.

For purchase and lease back transactions, we account for the transaction as a single arrangement. We allocate the consideration paid based on the relative fair value of the aircraft and lease. The fair value of the lease may include a lease premium or discount, which is recorded as a favorable or unfavorable lease intangible.

Finance Leases—From time to time the Company enters into finance lease arrangements that include a lessee obligation to purchase the leased equipment at the end of the lease term, a bargain purchase option, or provides for minimum lease payments with a present value that equals or exceeds substantially all of the fair value of the leased equipment at the date of lease inception. Net investment in finance leases represents the minimum lease payments due from lessee, net of unearned income. The lease payments are segregated into principal and interest components similar to a loan. Unearned income is recognized on an effective interest method over the lease term and is recorded as lease income. The principal component of the lease payment is reflected as a reduction to the net investment in finance leases. Revenue is not recognized when collection is not reasonably assured. When collectability is not reasonably assured, the lessee is placed on non-accrual status and revenue is recognized when cash payments are received.

Asset sales revenue—Asset sales revenue primarily consists of the transaction price related to the sale of aircraft and aircraft engines from the Company’s Aviation Leasing segment. From time to time, the Company may also assign the related lease agreements to the customer as part of the sale of these assets. The Company routinely sells leasing equipment to customers and such transactions are considered recurring and ordinary in nature to its business. As such, these sales are accounted for within the scope of ASC 606. Revenue is recognized when a performance obligation is satisfied by transferring control of an asset to the customer along with corresponding costs of sales.

Leasing Arrangements—At contract inception, the Company evaluates whether an arrangement is or contains a lease for which it is the lessee (that is, arrangements which provide the Company with the right to control a physical asset for a period of time). Operating lease right-of-use (“ROU”) assets are included in Other non-current assets and lease liabilities are included in Other current and non-current liabilities. Finance lease ROU assets are recognized in Other non-current assets and lease liabilities are recognized in Other current and non-current liabilities.

All lease liabilities are measured at the present value of the unpaid lease payments, discounted using the Company’s incremental borrowing rate based on the information available at commencement date of the lease. ROU assets, for both operating and finance leases, are initially measured based on the lease liability, adjusted for prepaid rent and lease incentives. Operating lease ROU assets are subsequently measured at the carrying amount of the lease liability adjusted for prepaid or accrued lease payments and lease incentives. The finance lease ROU assets are subsequently amortized using the straight-line method.

Operating lease expenses are recognized on a straight-line basis over the lease term. With respect to finance leases, amortization of the ROU asset is presented separately from interest expense related to the finance lease liability and is recorded in Operating expenses. Variable lease payments, which are primarily based on usage, are recognized when the associated activity occurs.

The Company has elected to combine lease and non-lease components for all lease contracts where it is the lessee. Additionally, for arrangements with lease terms of 12 months or less, the Company does not recognize ROU assets, and lease liabilities and lease payments are recognized on a straight-line basis over the lease term with variable lease payments recognized in the period in which the obligation is incurred.

During the year ended December 31, 2025, 45 aircraft were sold for a gain of $50.1 million, which was recognized within gain on sale to the 2025 Partnership. The aircraft sales were accounted for under ASC 610-20, Other Income — Gains and Losses from the Derecognition of Nonfinancial Assets, as they were non-recurring in nature and not considered part of the Company’s ordinary activities.

Concentration of Credit Risk—The Company is subject to concentrations of credit risk with respect to amounts due from customers and lessees. The Company attempts to limit its credit risk by performing ongoing credit evaluations. The Company earned 13% and 10% of its revenue from two customers in the Aerospace Products segment during the twelve months ended December 31, 2025. No single customer or lessee accounted for greater than 10% of total revenue during the years ended December 31, 2024 and 2023.

The Company maintains cash and restricted cash balances, which generally exceed federally insured limits, and subject it to credit risk, in high credit quality financial institutions. The Company monitors the financial condition of these institutions and has not experienced any losses associated with these accounts.

Allowance for Doubtful Accounts—The Company determines the allowance for doubtful accounts based on its assessment of the collectability of its leasing receivables, notes receivables and inventory sales. In assessing the allowance, the Company considers past collection history and specific risks identified among uncollected accounts. The assessment of collectability of its leasing receivables, notes receivables and inventory sales is done quarterly, on a customer-by-customer basis. Receivables are written off after all reasonable means to collect the full amount have been exhausted. The activity in the allowance for doubtful accounts is as follows:

Economic sanctions and export controls against Russia and Russia’s aviation industry were imposed due to its invasion of Ukraine during the first quarter of 2022. As a result of the sanctions imposed on Russian airlines, the Company terminated all lease agreements with Russian airlines and its allowance for doubtful accounts at December 31, 2024 includes all accounts receivable exposure to Russian and Ukrainian lessees.

Additionally, the Board of Directors declared cash dividends on the Series C Preferred Shares of $2.06, $2.06, $2.06 per share for the years ended December 31, 2025, 2024 and 2023, respectively, the Series D Preferred Shares of $2.38, $2.38 and $1.78 per share for the year ended December 31, 2025, 2024 and 2023, the Series A Preferred Shares of $1.55 and $2.06 per share for the years ended December 31, 2024, and 2023, respectively, and the Series B Preferred Shares of $2.00 and $2.00 per share for the years ended December 31, 2024 and 2023, respectively.

Cash Flow Presentation—Included in net cash (used in) provided by operating activities are inflows from the sale of engine modules and parts that were on engines originally purchased and reported as Leasing equipment, net. The purchase of the original engine was reported as an outflow in net cash used in investing activities at the time of purchase through the Acquisition of leasing equipment line item. As part of the Aerospace products business, the Company breaks down generally unserviceable engines with the intent to manufacture modules and parts for creation and sale of new assets. To manufacture the modules and parts and bring them into a salable condition, the Company spends significant costs, often over multiple reporting periods, for new inventory and capitalizable labor (e.g., engineering) that are included in net cash (used in) provided by operating activities as components of the changes in the related working capital accounts.

Additionally, the Company buys inventory from third parties with the intent to use the parts in the manufacturing of the items discussed above, which is reported as an outflow in net cash (used in) provided by operating activities. When rebuilding whole engines for resale, for which the cash inflow upon sale is reported as a cash inflow from investing activities, the Company will transfer modules and parts needed (those purchased from third parties as well as parts from engines previously transferred to inventory from leasing equipment and rebuilt as discussed above) in the rebuild from inventory to leasing equipment.

With respect to purchases of aircraft and engines, when the expected predominant source of cash inflows from the acquired leasing equipment at the time of acquisition is from leasing activities, the related cash outflow is reported as an outflow in net cash used in investing activities. When the expected predominant source of cash inflows is from sales transactions, the related cash outflow is reported as an outflow in net cash (used in) provided by operating activities.

Recently Adopted Accounting Pronouncements—In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. This ASU modifies the disclosure and presentation requirements of reportable segments. The new guidance requires the disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit and loss. In addition, the new guidance enhances interim disclosure requirements, clarifies circumstances in which an entity can disclose multiple segment measures of profit or loss, provides new segment disclosure requirements for entities with a single reportable segment, and contains other disclosure requirements. This standard is effective retrospectively for all public entities for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted this guidance in the fourth quarter of 2024, and it did not have a material impact on its consolidated financial statements and related disclosures.

In August 2023, the FASB issued ASU 2023‑05, Business Combinations – Joint Venture Formations, which requires that joint ventures, upon formation, apply a new basis of accounting by initially measuring assets and liabilities at fair value. The amendments in ASU 2023‑05 are effective for joint ventures that are formed on or after January 1, 2025. The Company adopted this guidance in the first quarter of 2025. The adoption of ASU 2023-05 did not have a material impact on the Company’s consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures. This ASU enhances the transparency and decision usefulness of income tax disclosures by expanding the disclosures of an entity’s income tax rate reconciliation and disaggregation of income taxes paid and income tax expense. Under the new guidance, public business entities must annually disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold, if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income (loss) by the applicable statutory income tax rate. This standard is effective prospectively for all public entities for annual periods beginning after December 15, 2024, with early adoption and retrospective application permitted. The Company adopted this guidance, prospectively, in the fourth quarter of 2025. See note 11 for the Company’s income tax disclosures.

Accounting Pronouncements Not Yet Adopted—In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. In January 2025, the FASB issued Clarifying the Effective Date (“ASU 2025-01”) to add some clarity around the effective date of the guidance. This ASU requires disaggregated information for specified categories of expenses, including inventory purchases, employee compensation, depreciation, amortization, and depletion, to be presented in certain expense captions on the face of the income statement. This standard is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption and either prospective or retrospective application permitted. The Company is currently assessing the impact this guidance will have on its consolidated financial statements and related disclosures.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides a practical expedient in developing reasonable and supportable forecasts as apart of estimating expected credit losses, allowing entities to assume that current conditions as of the balance sheet date do not change for the remaining life of the asset. The amendments in ASU 2025-05 are effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. The Company is currently evaluating the impact of this update on its consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270), which is improves the navigability of the required interim disclosures, provides clarity as to when it is applicable, and provides additional guidance on what disclosures are required in interim reporting periods by establishing a disclosure principle. The guidance is effective for interim reporting periods beginning in 2028 and can be applied either prospectively or retrospectively. The Company is currently determining its method of adoption.
