Note 1. Summary of Significant Accounting Policies

Organization

Aircastle Limited (“Aircastle,” the “Company,” “we,” “us” or “our”) is a Bermuda company that was incorporated on October 29, 2004, under the provisions of Section 14 of the Companies Act of 1981 of Bermuda. Aircastle’s business is acquiring, leasing, managing and selling commercial jet aircraft.

The Company is controlled by affiliates of Marubeni Corporation (“Marubeni”) and Mizuho Leasing Company, Limited (“Mizuho Leasing” and, together with Marubeni, our “Shareholders”).

Aircastle is a holding company and conducts its business through subsidiaries that are wholly owned, either directly or indirectly, by Aircastle.

Basis of Presentation and Principles of Consolidation

The consolidated financial statements presented are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”).

The accompanying consolidated financial statements are unaudited and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial reporting and, in our opinion, reflect all adjustments, including normal recurring items, which are necessary to present fairly the results for interim periods. Operating results for the periods presented are not necessarily indicative of the results that may be expected for the entire year. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been omitted in accordance with the rules and regulations of the SEC. However, we believe that the disclosures are adequate to make the information presented not misleading. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended February 28, 2025.

The consolidated financial statements include the accounts of Aircastle and all its subsidiaries, including any Variable Interest Entity (“VIE”) of which Aircastle is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation.

We manage and analyze our business and report our results of operations based on one operating and reportable segment: leasing, financing, selling and managing commercial flight equipment. Our Chief Executive Officer is the chief operating decision maker (the “CODM”). As a single reportable segment entity, the CODM utilizes consolidated net income to evaluate segment performance and allocate resources. The significant segment expenses and other segment items, such as total assets, that are provided to the CODM align with expense information that is included in the Company’s consolidated balance sheets and statements of income.

The Company’s management has reviewed and evaluated all events or transactions for potential recognition and/or disclosure subsequent to the balance sheet date of May 31, 2025, through the date on which the consolidated financial statements included in this Form 10-Q were issued.

Risk and Uncertainties

In the normal course of business, Aircastle encounters several significant types of economic risk, including credit, market, aviation industry and capital market risks. Credit risk is the risk of a lessee’s inability or unwillingness to make contractually required payments and to fulfill its other contractual obligations to Aircastle. Market risk reflects the change in the value of financings due to changes in interest rate spreads or other market factors, including the value of collateral underlying financings. Aviation industry risk is the risk of a downturn in the commercial aviation industry which could adversely impact a lessee’s ability to make payments, increase the risk of early lease terminations and depress lease rates and the value of the Company’s aircraft. 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.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. While Aircastle believes the estimates and related assumptions used in the preparation of the consolidated financial statements are appropriate, actual results could differ from those estimates.

Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASC 740”). ASC 740 enhances the transparency of income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The standard requires disclosure of specific categories in the rate reconciliation, using both percentages and reporting currency amounts, as well as disclosure of income taxes paid, net of refunds received, disaggregated by federal, state, and foreign taxes and individual jurisdictions. The standard is effective for annual periods beginning after December 15, 2024, and will be adopted by the Company for the year ended February 28, 2026. The amendments in ASU 2023-09 should be applied on a prospective basis; however, retrospective application to all prior periods presented in the annual financial statements is permitted. The Company does not anticipate that the adoption of the standard will have a material impact on our consolidated financial statements.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This standard requires entities to provide additional disclosure around certain costs and expenses presented within the Income Statement. This standard aims to improve the disclosures around the entity’s expenses and address requests from investors for more detailed information about the types of expenses. The standard is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The Company does not anticipate that the adoption of the standard will have a material impact on its consolidated financial statements or related disclosures.

Note 2. Fair Value Measurements

Fair value measurements and disclosures require the use of valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs.

Assets Measured at Fair Value on a Recurring Basis

The following tables set forth our financial assets as of May 31, 2025 and February 28, 2025, that we measured at fair value on a recurring basis by level within the fair value hierarchy. Assets measured at fair value are classified in their entirety based on the lowest level of input that is significant to their fair value measurement.

			Fair Value Measurements at May 31, 2025 Using Fair Value Hierarchy
	Fair Value as of May 31, 2025		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Valuation Technique
Assets:
Cash and cash equivalents	$	223,230	$	223,230	$	—	$	—	Market
Investments, at fair value:
Investment in debt securities	$	5,029	$	—	$	—	$	5,029	Income
Investment in equity securities	5,340		1,442		—		3,898		Market/Income
Total investments, at fair value	$	10,369	$	1,442	$	—	$	8,927

			Fair Value Measurements at February 28, 2025 Using Fair Value Hierarchy
	Fair Value as of February 28, 2025		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Valuation Technique
Assets:
Cash and cash equivalents	$	279,052	$	279,052	$	—	$	—	Market
Investments, at fair value:
Investment in debt securities	$	5,029	$	—	$	—	$	5,029	Income
Investment in equity securities	4,883		985		—		3,898		Market/Income
Total investments, at fair value	$	9,912	$	985	$	—	$	8,927

Our cash and cash equivalents consist largely of money market securities that are highly liquid and easily tradable. These securities are valued using inputs observable in active markets for identical securities (Level 1). Our investments in debt and equity securities consist of notes and shares received as a result of claims settlements from various airline customers that had entered into bankruptcy proceedings or similar-type restructurings. Our investment in equity securities that are traded in an active market have been valued using quoted market prices (Level 1). Our investments in other equity securities and debt securities for which there is no active market or there is limited market data have been valued using the income approach (Level 3).

For the three months ended May 31, 2025, we had no transfers into or out of Level 3.

Assets Measured at Fair Value on a Non-recurring Basis

We measure the fair value of certain assets and liabilities on a non-recurring basis, when U.S. GAAP requires the application of fair value, including events or changes in circumstances that indicate the carrying amounts of these assets may not be recoverable. Assets subject to these measurements include our aircraft and unconsolidated equity method investment.

We record aircraft at fair value when we determine the carrying value may not be recoverable. Fair value measurements for aircraft in impairment tests are based on the average of the market approach (Level 2 or 3), which includes third-party appraisal data, and an income approach (Level 3), which includes the Company’s assumptions and appraisal data as to the present value of future cash proceeds from leasing and selling aircraft. Level 3 valuations contain significant non-observable inputs. See “Aircraft Valuation” below for further information.

We account for our unconsolidated equity method investment under the equity method of accounting. Our investment is recorded at cost and is adjusted by undistributed earnings and losses and the distributions of dividends and capital. This investment is reviewed for impairment whenever events or changes in circumstances indicate the fair value is less than its carrying value and the decline is other-than-temporary.

Financial Instruments

Our financial instruments, other than cash, consist principally of cash equivalents, accounts receivable, investments in debt and equity securities, accounts payable and secured and unsecured financings. The fair value of cash and cash equivalents, accounts receivable and accounts payable approximates the carrying value of these financial instruments because of their short-term nature.

The fair value of our investments, which consist of debt and equity securities, have been valued using either quoted market prices to the extent such securities are traded in an active market (Level 1), or using the income approach for those securities where there is no active market or there is limited market data (Level 3). The fair value of our senior notes is estimated using quoted market prices (Level 1), whereas all our other financings are valued using a discounted cash flow analysis, based on our current incremental borrowing rates for similar types of borrowing arrangements (Level 2).

Aircraft Valuation

Impairment of Flight Equipment

During the three months ended May 31, 2025, the Company recorded transactional impairment charges totaling $5.1 million related to engine redeliveries and 1 aircraft lease termination. The Company recognized $18.7 million of revenue related to maintenance, security deposits, and the reversal of lease incentive liabilities for these engines and aircraft during the three months ended May 31, 2025.

Recoverability Assessment

We perform a recoverability assessment of all our aircraft and other flight equipment on a quarterly basis and annually during the third quarter of each fiscal year.

We perform a recoverability test when events or changes in circumstances, or indicators, suggest that the carrying amount or net book value of an aircraft or other flight equipment may not be recoverable. For assets with indicators of impairment, we measure whether the estimated future undiscounted net cash flows expected to be generated by the asset exceed its net book value. The undiscounted cash flows consist of cash flows from currently contracted lease rentals and maintenance payments, future projected lease rates and maintenance payments, transition costs, estimated down time, and estimated residual or scrap values for an aircraft. In the event that an aircraft does not meet the recoverability test, the aircraft will be adjusted to fair value, resulting in an impairment charge.

Management assumptions are based on current and future expectations of the global demand for a particular aircraft type and historical experience in the aircraft leasing market and aviation industry, as well as information received from third-party industry sources. The factors considered in estimating the undiscounted cash flows are impacted by changes in future periods due to changes in projected lease rental and maintenance payments, residual values, economic conditions, technology, airline demand for a particular aircraft type and other factors, such as the location of the aircraft and accessibility to records and technical documentation.

If our estimates or assumptions change, including those related to our customers that have entered judicial insolvency proceedings or similar-type proceedings or restructurings, we may revise our cash flow assumptions and record future impairment charges. While we believe that the estimates and related assumptions used in our recoverability assessments are appropriate, actual results could differ from those estimates.

Update on Russian Aircraft

The Company leased 9 aircraft to Russian airlines that were unrecoverable following Russia’s invasion of Ukraine in February 2022. The Company filed claims against the reinsurers of the Russian airlines’ insurance and the Company’s contingent and possessed insurance policies (“C&P Policies”) seeking indemnity.

During the years ended February 28, 2025 and February 29, 2024, the Company received aggregate cash settlement proceeds of $92.7 million in settlement of certain of the Company’s claims under the Russian airlines’ insurance and the Company’s C&P Policies.

The receipt of the insurance proceeds serve to mitigate, in part, the Company’s losses under its aviation insurance policies. The Company remains in settlement discussions with some of the remaining insurers under its C&P Policies. However, the collection, timing and amount of any future recoveries, including those related to insurance litigation, remain uncertain. Accordingly, at this time, the Company can give no assurance as to when or what amounts it may ultimately collect with respect to these matters.

Subsequent to May 31, 2025, the Company entered into a settlement agreement with certain additional C&P insurers for an aggregate settlement amount of $14.7 million, which will be recognized in its consolidated statement of income in the second quarter of 2025.

The Unsecured Term Loan Credit Agreement contains, among other customary provisions, a $1.1 billion minimum net worth covenant, a 2.0:1.0 minimum interest coverage ratio covenant, and a 1.25:1.0 minimum unencumbered asset ratio. The Company and Aircastle (Ireland) Designated Activity Company, a wholly-owned subsidiary of the Company, agreed to fully and unconditionally guarantee AALLC’s obligations under the Unsecured Term Loan Credit Agreement.

Revolving Credit Facilities

As of May 31, 2025, we had $20.0 million outstanding under our revolving credit facilities and had $2.1 billion available for borrowing.

As of May 31, 2025, we were in compliance with all applicable covenants in our financings.

The sources of income from continuing operations before income taxes and earnings of our unconsolidated equity method investment for the three months ended May 31, 2025 and 2024, were as follows:

	Three Months Ended May 31,
	2025		2024
U.S. operations	$	10,090	$	4,996
Non-U.S. operations	51,525		14,138
Income from continuing operations before income taxes and earnings of unconsolidated equity method investment	$	61,615	$	19,134

Our U.S.-based aircraft-owning subsidiary is taxed in the United States. Our non U.S.-based aircraft-owning subsidiaries generally earn income from sources outside the United States and typically are not subject to U.S. federal, state or local income taxes.

We have a U.S.-based subsidiary which provides management services to our subsidiaries and is subject to U.S. federal, state and local income taxes. We also have Ireland and Singapore-based subsidiaries which provide management services to our non-U.S. subsidiaries and are subject to tax in those respective jurisdictions.

We recognized income tax provisions of $12.7 million and $3.6 million for the three months ended May 31, 2025 and 2024, respectively. Our effective tax rate for the three months ended May 31, 2025 and 2024, was 20.6% and 18.7%, respectively. The increase in our effective tax rate is primarily attributable to the mix of profits between the various jurisdictions in which we operate.

Ireland and Bermuda Tax Law Changes

On December 18, 2023, Ireland enacted Finance (No. 2) Bill 2023 (the “Finance Bill”) which includes legislative changes for new tax measures and amendments to the Irish tax code, such as provisions to implement the Pillar Two GloBE rules, new outbound payment rules, and a dividend withholding tax, among other changes. The Finance Bill did not have a significant impact on our consolidated financial statements for the three months ended May 31, 2025.

On December 18, 2023, Bermuda enacted the Bermuda CIT Act, which imposes the 15% Bermuda CIT that applies to Bermuda businesses that are part of multinational enterprise groups with annual revenue of €750 million or more and is effective for tax years beginning on or after January 1, 2025. The Company has appropriately considered the impact of the Bermuda CIT and its impact on current and deferred income taxes.

OVERVIEW

Aircastle acquires, leases, and sells commercial jet aircraft to airlines throughout the world. We are a leading secondary market investor that sources aircraft through various acquisition channels that primarily include other aircraft lessors, airlines through purchase-leaseback transactions, financial institutions and other aircraft owners, and aircraft manufacturers. We have significant experience in successfully managing aircraft throughout their life cycle, including lease and technical management, aircraft redeliveries, transitions, and sales or disposals. We sell aircraft and engine assets, either with a lease attached or on a part-out basis, with the aim of generating profits and reinvesting proceeds. Our aircraft are managed by an experienced team based in the United States, Ireland and Singapore.

As of May 31, 2025, we owned and managed on behalf of our joint venture 272 aircraft leased to 78 airline customers located in 47 countries. The Net Book Value of our fleet was $8.1 billion as of May 31, 2025. The weighted average age of our fleet was 8.9 years, and the weighted average remaining lease term was 5.6 years. The weighted average utilization rate of our fleet was over 99% for the three months ended May 31, 2025. During the three months ended May 31, 2025, we purchased 12 aircraft and sold 14 aircraft and other flight equipment. As of May 31, 2025, we had commitments to purchase 23 aircraft for $1.2 billion, with deliveries through December 2027, which included estimated amounts for pre-delivery deposits, contractual price escalations and other adjustments.

Our total revenues, net income and Adjusted EBITDA were $259.8 million, $49.3 million and $231.9 million, respectively, for the three months ended May 31, 2025. Cash flow provided by operating activities was $127.9 million for the three months ended May 31, 2025. The Company’s financial performance reflects strong global passenger demand for air travel, as well as robust demand for our aircraft driven by ongoing delivery delays and supply chain challenges faced by Original Equipment Manufacturers. Increased lease extension requests and strong gains from aircraft and engine sales also contributed positively to our financial results.

Growth in commercial air traffic has been correlated with world economic activity and has historically grown at a rate one to two times that of global gross domestic product growth. This expansion of air travel has driven growth in the world aircraft fleet. There are approximately 27,000 commercial mainline passenger and freighter aircraft in the world fleet today. Aircraft leasing companies own approximately 50% of the world’s commercial passenger jet aircraft. Under normal circumstances, we would expect the global fleet to continue expanding at a 2 to 3% average annual rate.

Although recent tariff announcements have introduced some volatility to the global aviation sector, we believe that the current operating environment for airlines continues to be favorable for us and the wider commercial aircraft leasing industry. We believe our portfolio, which is primarily comprised of new technology and mid-life, narrow-body aircraft, will remain attractive for our airline customers, enabling them to respond to the growing demand of global air travel. As a leading secondary market investor, we believe that our long-standing business strategy of maintaining conservative leverage and limiting long-term financial commitments positions us well to take advantage of new investment opportunities as they arise.

We employ a team of experienced senior professionals with extensive industry and financial experience. Our leadership team has an average of more than 30 years of relevant industry experience and has effectively enabled us to manage through prior downturns in the aviation industry, such as the COVID-19 pandemic, the 2008 global financial crisis, and the September 11, 2001 terror attacks. We continue to closely monitor the ongoing geopolitical developments in the Middle East; our airline customers located in the Middle East comprised 5% of both our Net Book Value and lease rental revenue as of and for the three months ended May 31, 2025. See Item 1A. “Risk Factors – Risks Related to Our Operations – Events outside of our control, including economic downturns, the threat or realization of epidemic or pandemic diseases, terrorist attacks, war or armed hostilities between countries or non-state actors, and natural disasters may adversely affect the demand for air travel, the financial condition of our lessees and of the aviation industry more broadly, and may ultimately impact our business” in our Annual Report on Form 10-K for the year ended February 28, 2025.

We believe we have sufficient liquidity to meet our contractual obligations over the next twelve months. As of July 1, 2025, total liquidity of $2.6 billion included $2.0 billion of undrawn credit facilities, $0.5 billion of projected adjusted operating cash flows and contracted asset sales and $0.1 billion of unrestricted cash through July 1, 2026.

Acquisitions and Sales

During the three months ended May 31, 2025, we purchased 12 aircraft for $464.8 million. As of May 31, 2025, we had commitments to purchase 23 aircraft for $1.2 billion, with delivery through December 2027, which included estimated amounts for pre-delivery deposits, contractual price escalations and other adjustments. As of July 1, 2025, we have purchased 4 additional aircraft and have commitments to purchase 22 aircraft for $1.1 billion.

During the three months ended May 31, 2025, we sold 14 aircraft and other flight equipment for net proceeds of $226.8 million and recognized gains on the sale or disposition of flight equipment totaling $30.3 million. As of July 1, 2025, we have sold 1 additional aircraft.

Fiscal Year 2025 Lease Expirations and Lease Placements

As of July 1, 2025, we had 1 off-lease aircraft and 6 aircraft with a lease expiring in fiscal year 2025, which combined account for approximately 1% of our Net Book Value at May 31, 2025, remaining to be placed or sold. Of these 7 aircraft, we expect to transition 3 aircraft to a new lessee and sell or part out the other 4 aircraft.

Fiscal Years 2026 to 2029 Lease Expirations and Lease Placements

Taking into account lease and sale commitments, we currently have the following number of aircraft with lease expirations scheduled in the fiscal years 2026 to 2029, representing the percentage of our Net Book Value as of May 31, 2025, specified below:

•2026: 32 aircraft, representing 10%;

•2027: 35 aircraft, representing 10%;

•2028: 32 aircraft, representing 9%; and

•2029: 36 aircraft, representing 12%.

Finance

We operate in a capital-intensive industry and have a demonstrated track record of raising substantial amounts of capital from debt and equity investors. Since our inception in late 2004, we have raised $2.6 billion in equity capital from private and public investors. We also have raised $23.8 billion in debt capital from a variety of sources, including the unsecured bond market, commercial banks, export credit agency-backed debt, the aircraft securitization market and Japanese Operating Lease with Call Option financings, which have been originated by Marubeni. The diversity and global nature of our financing sources demonstrate our ability to adapt to changing market conditions and seize new growth opportunities.

We intend to fund new investments through cash on hand, funds generated from operations, maintenance payments received from lessees, equity offerings, unsecured bond offerings, borrowings secured by our aircraft, draws under our revolving credit facilities and proceeds from any future aircraft sales. We may repay all or a portion of such borrowings from time to time with the net proceeds from subsequent long-term debt financings, additional equity offerings or cash generated from operations and asset sales. Therefore, our ability to execute our business strategy, particularly the acquisition of additional commercial jet aircraft or other aviation assets, depends to a significant degree on our ability to obtain additional debt and equity capital on terms we deem attractive.

Revenues

Total revenues increased $54.7 million, attributable to:

Lease rental revenue increased $20.5 million, primarily attributable to an increase of $40.4 million related to 61 aircraft purchased since March 1, 2024.

This was partially offset by:

•an $18.3 million decrease related to the sale of 39 aircraft since March 1, 2024; and

•a $1.6 million decrease due to lease extensions, amendments, transitions and other changes.

26

Amortization of lease premiums, discounts and lease incentives:

	Three Months Ended May 31,
	2025		2024
	(Dollars in thousands)
Amortization of lease premiums	$	(1,887)	$	(3,242)
Amortization of lease discounts	3,523		694
Amortization of lease incentives	1,130		(4,101)
Amortization of lease premiums, discounts and incentives	$	2,766	$	(6,649)

The amortization of lease discounts increased $2.8 million due to the acquisition of aircraft.

The amortization of lease incentives decreased $5.2 million primarily due to the reversal of lease incentive liabilities related to 2 engine redeliveries.

Maintenance revenue. For the three months ended May 31, 2025 and 2024, we recorded $38.1 million and $42.1 million of maintenance revenue, respectively, primarily related to maintenance payments received by us and recognized into income as a result of scheduled aircraft lease expirations and engine redeliveries.

Gain on sale or disposition of flight equipment. During the three months ended May 31, 2025, we sold 14 aircraft and other flight equipment for gains totaling $30.3 million.

During the three months ended May 31, 2024, we sold 2 aircraft and other flight equipment for gains totaling $1.0 million.

Operating expenses

Total operating expenses increased $9.1 million, attributable to:

Depreciation expense increased $6.5 million, primarily attributable to an increase of $15.8 million related to 57 aircraft acquired since March 1, 2024. This increase was partially offset by a decrease of $9.9 million related to 39 aircraft sold since March 1, 2024.

Interest, net increased $4.0 million due to a higher average cost of borrowing and a higher weighted average debt outstanding of $273.1 million.

Impairment of flight equipment. During the three months ended May 31, 2025, the Company recorded transactional impairment charges totaling $5.1 million related to engine redeliveries and 1 aircraft lease termination. The Company recognized $18.7 million of revenue related to maintenance, security deposits, and the reversal of lease incentive liabilities for these engines and aircraft during the three months ended May 31, 2025.

During the three months ended May 31, 2024, the Company recorded a transactional impairment charge of $5.2 million related to a scheduled aircraft lease expiration. The Company recognized $18.0 million of maintenance revenue for this aircraft during the three months ended May 31, 2024.

Other expense

Total other expense increased by $3.1 million. During the three months ended May 31, 2025, we recognized a $3.0 million loss on the early extinguishment of one of our secured term financings and the related write-off of unamortized financing costs.

Income tax provision

Our income tax provision was $12.7 million and $3.6 million, and our effective tax rate was 20.6% and 18.7% for the three months ended May 31, 2025 and 2024, respectively. The increase in the income tax provision is primarily attributable to the mix of profits between the various jurisdictions in which we operate.

LIQUIDITY AND CAPITAL RESOURCES

Our business is very capital intensive, requiring significant investments in order to expand our fleet and to maintain and improve our existing portfolio. Our operations have historically generated a significant amount of cash, primarily from lease rentals and maintenance collections. We have also met our liquidity and capital resource needs by utilizing several sources over time, including:

•unsecured indebtedness, including our current unsecured revolving credit facilities, unsecured term financings and senior notes;

•various forms of borrowing secured by our aircraft, including term financings and limited recourse securitization financings for new aircraft acquisitions;

•asset sales; and

•issuance of common and preference shares.

Going forward, we expect to continue to seek liquidity from these sources and other sources, subject to pricing and conditions we consider satisfactory.

During the three months ended May 31, 2025, we met our liquidity and capital resource needs with $127.9 million of cash flows from operations and $226.8 million of proceeds from the sale or disposition of aircraft and other flight equipment.

As of May 31, 2025, the weighted average maturity of our secured and unsecured debt financings was 3.3 years, and we were in compliance with all applicable covenants. In addition, 98% of our total debt is unsecured and $8.0 billion of our Net Book Value is unencumbered.

We believe we have sufficient liquidity to meet our contractual obligations over the next twelve months. As of July 1, 2025, total liquidity of $2.6 billion included $2.0 billion of undrawn credit facilities, $0.5 billion of projected adjusted operating cash flows and contracted asset sales and $0.1 billion of unrestricted cash through July 1, 2026. In addition, we believe payments received from lessees and other funds generated from operations, unsecured bond offerings, borrowings secured by our aircraft, borrowings under our revolving credit facilities and other borrowings and proceeds from future aircraft sales will be sufficient to satisfy our liquidity and capital resource needs over the next twelve months. Our liquidity and capital resource needs include payments due under our aircraft purchase obligations, required principal and interest payments under our long-term debt facilities, expected capital expenditures, lessee maintenance payment reimbursements and lease incentive payments.

Cash Flows

	Three Months Ended May 31,
	2025		2024
	(Dollars in thousands)
Net cash flow provided by operating activities	$	127,872	$	147,004
Net cash flow used in investing activities	(249,175)		(164,584)
Net cash flow provided by financing activities	65,481		52,207

Operating Activities:

Cash flow provided by operating activities was $127.9 million and $147.0 million for the three months ended May 31, 2025 and 2024, respectively. The decrease is attributable to lower end of lease cash maintenance payments due to fewer aircraft returns during the three months ended May 31, 2025, as well as higher cash paid for interest.

Investing Activities:

Cash flow used in investing activities was $249.2 million and $164.6 million for the three months ended May 31, 2025 and 2024, respectively. The net increase of $84.6 million was primarily attributable to an increase of $254.7 million in the acquisition and improvement of flight equipment during the three months ended May 31, 2025. Additionally, cash proceeds were higher from the sale or disposition of aircraft and other flight equipment during the three months ended May 31, 2025, by $201.4 million.

Financing Activities:

Cash flow provided by financing activities was $65.5 million and $52.2 million for the three months ended May 31, 2025 and 2024, respectively. The increase of $13.3 million was primarily attributable to a $47.7 million increase in borrowings from secured and unsecured financings, net of repayments, during the three months ended May 31, 2025. These inflows were offset by a $17.3 million increase in maintenance and security deposits returned, net of receipts, and an $11.0 million increase in dividends paid.

Debt Obligations

For complete information on our debt obligations, see Note 8 in the Notes to the Unaudited Consolidated Financial Statements.

Contractual Obligations

Our contractual obligations primarily consist of principal and interest payments on debt financings, aircraft acquisitions and rent payments pursuant to our office leases. Total contractual obligations increased to $7.3 billion at May 31, 2025, from $6.7 billion at February 28, 2025, due to higher aircraft purchase commitments, outstanding debt and interest obligations.

Capital Expenditures

From time to time, we make capital expenditures to maintain or improve our aircraft. These expenditures include the cost of major overhauls necessary to place an aircraft in service and modifications made at the request of lessees. For the three months ended May 31, 2025 and 2024, we incurred a total of $13.7 million and $9.0 million, respectively, of capital expenditures, including lease incentives, related to the improvement of aircraft.

As of May 31, 2025, the weighted average age by Net Book Value of our aircraft was approximately 8.9 years. In general, the costs of operating an aircraft, including maintenance expenditures, increase with the age of the aircraft. Our lease agreements call for the lessee to be primarily responsible for maintaining the aircraft. Our leases may require the lessee to make periodic payments to us during the lease term to provide reserves for future major maintenance events. Provided a lessee performs scheduled maintenance of the aircraft, we are required to reimburse the lessee for scheduled maintenance payments. In certain cases, we are also required to make lessor contributions, in excess of amounts a lessee may have paid, towards the costs of maintenance events performed by or on behalf of the lessee. We may incur

30

additional maintenance and modification costs in the future in the event we are required to remarket an aircraft, or a lessee fails to meet its maintenance obligations under the lease agreement.

Actual maintenance payments to us by lessees in the future may be less than projected as a result of a number of factors, such as in the event of a lessee default. Maintenance reserves may not cover the entire amount of actual maintenance expenses incurred and, where these expenses are not otherwise covered by the lessees, there can be no assurance that our operational cash flow and maintenance reserves will be sufficient to fund maintenance requirements, particularly as our aircraft age. See Item 1A. “Risk Factors – Risks Related to Our Leases – If lessees are unable to fund their maintenance obligations on our aircraft, we may incur increased costs at the conclusion of the applicable lease” in our Annual Report on Form 10-K for the year ended February 28, 2025.

Off-Balance Sheet Arrangements

We have an unconsolidated equity method investment in an aircraft leasing entity with Mizuho Leasing. We hold a 25% equity interest in this entity, which was established to help expand our base of new business opportunities. As of May 31, 2025, the Net Book Value of its 8 aircraft was $241.2 million.

The assets and liabilities of this entity are not included in our consolidated balance sheets, and we record our net investment under the equity method of accounting. See Note 7 in the Notes to the Unaudited Consolidated Financial Statements.

Foreign Currency Risk and Foreign Operations

At May 31, 2025, approximately 99% of our leases were payable to us in U.S. dollars. However, we incur Euro- and Singapore dollar-denominated expenses in connection with our subsidiaries in Ireland and Singapore. For the three months ended May 31, 2025, expenses, such as payroll and office costs, denominated in currencies other than the U.S. dollar totaled $6.2 million in U.S. dollar equivalents and represented approximately 27% of total selling, general and administrative expenses.

Our international operations are a significant component of our business strategy and permit us to more effectively source new aircraft, service the aircraft we own and maintain contact with our lessees. Therefore, our international operations and our exposure to foreign currency risk will likely increase over time. Although we have not yet entered into foreign currency hedges, if our foreign currency exposure increases, we may enter into hedging transactions in the future to mitigate this risk. For the three months ended May 31, 2025 and 2024, we incurred insignificant net gains and losses on foreign currency transactions.

Management’s Use of EBITDA and Adjusted EBITDA

We define EBITDA as income (loss) from continuing operations before interest expense, income taxes, and depreciation and amortization. We use EBITDA to assess our consolidated financial and operating performance, and we believe this non-U.S. GAAP measure is helpful in identifying trends in our performance.

This measure provides an assessment of controllable expenses and affords management the ability to make decisions which are expected to facilitate meeting current financial goals, as well as achieving optimal financial performance. It provides an indicator for management to determine if adjustments to current spending decisions are needed.

EBITDA provides us with a measure of operating performance because it assists us in comparing our operating performance on a consistent basis as it removes the impact of our capital structure (primarily interest charges on our outstanding debt) and asset base (primarily depreciation and amortization) from our operating results. Accordingly, this metric measures our financial performance based on operational factors that management can impact in the short-term, namely the cost structure, or expenses, of the organization. EBITDA is one of the metrics used by senior management and the Board of Directors to review the consolidated financial performance of our business.

We define Adjusted EBITDA as EBITDA (as defined above) further adjusted to give effect to adjustments required in calculating covenant ratios and compliance as that term is defined in the indenture governing our senior unsecured notes. Adjusted EBITDA is a material component of these covenants.

31

The table below shows the reconciliation of net income to EBITDA and Adjusted EBITDA for the three months ended May 31, 2025 and 2024:

	Three Months Ended May 31,
	2025		2024
Net income	$	49,287	$	16,081
Depreciation	95,816		89,358
Amortization of lease premiums, discounts and incentives	(2,766)		6,649
Interest, net	68,841		64,813
Income tax provision	12,721		3,572
EBITDA	$	223,899	$	180,473
Adjustments:
Impairment of flight equipment	5,066		5,211
Loss on extinguishment of debt	2,973		—
Adjusted EBITDA	$	231,938	$	185,684

Limitations of EBITDA and Adjusted EBITDA

An investor or potential investor may find EBITDA and Adjusted EBITDA important measures in evaluating our performance, results of operations and financial position. We use these non-U.S. GAAP measures to supplement our U.S. GAAP results in order to provide a more complete understanding of the factors and trends affecting our business.

EBITDA and Adjusted EBITDA have limitations as analytical tools and should not be viewed in isolation or as substitutes for U.S. GAAP measures of income (loss). Material limitations in making the adjustments to our income (loss) to calculate EBITDA and Adjusted EBITDA, and using these non-U.S. GAAP measures as compared to U.S. GAAP net income (loss), income (loss) from continuing operations and cash flows provided by or used in operations, include:

•depreciation and amortization, though not directly affecting our current cash position, represent the wear and tear and/or reduction in value of our aircraft, which affects the aircraft’s availability for use and may be indicative of future needs for capital expenditures;

•the cash portion of income tax provision (benefit) generally represents charges (gains), which may significantly affect our financial results; and

•adjustments required in calculating covenant ratios and compliance as that term is defined in the indenture governing our senior unsecured notes, which may not be comparable to similarly titled measures used by other companies.

EBITDA and Adjusted EBITDA are not alternatives to net income (loss), income (loss) from operations or cash flows provided by or used in operations as calculated and presented in accordance with U.S. GAAP. You should not rely on these non-U.S. GAAP measures as a substitute for any such U.S. GAAP financial measure. We strongly urge you to review the reconciliations to U.S. GAAP net income (loss), along with our consolidated financial statements included elsewhere in this report. We also strongly urge you not to rely on any single financial measure to evaluate our business. In addition, because EBITDA and Adjusted EBITDA are not measures of financial performance under U.S. GAAP and are susceptible to varying calculations, EBITDA and Adjusted EBITDA as presented in this report, may differ from and may not be comparable to similarly titled measures used by other companies.

32

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate risk is the exposure to loss resulting from changes in the level of interest rates and the spread between different interest rates. These risks are highly sensitive to many factors, including U.S. monetary and tax policies, U.S. and international economic factors and other factors beyond our control. We are exposed to changes in the level of interest rates and to changes in the relationship or spread between interest rates. Our primary interest rate exposures relate to our floating-rate debt obligations. Rent payments under our aircraft lease agreements typically do not vary during the term of the lease according to changes in interest rates. However, our borrowing agreements generally require payments based on a variable interest rate index, such as SOFR or an alternative reference rate. Therefore, to the extent our borrowing costs are not fixed, increases in interest rates may reduce our net income by increasing the cost of our debt without any corresponding increase in rents or cash flow from our securities.

Sensitivity Analysis

The following discussion about the potential effects of changes in interest rates is based on a sensitivity analysis, which models the effects of hypothetical interest rate shifts on our financial condition and results of operations. Although we believe a sensitivity analysis provides the most meaningful analysis permitted by the rules and regulations of the SEC, it is constrained by several factors, including the necessity to conduct the analysis based on a single point in time and by the inability to include the extraordinarily complex market reactions that normally would arise from the market shifts modeled. Although the following results of a sensitivity analysis for changes in interest rates may have some limited use as a benchmark, they should not be viewed as a forecast. This forward-looking disclosure also is selective in nature and addresses only the potential interest expense impacts on our financial instruments. It also does not include a variety of other potential factors that could affect our business as a result of changes in interest rates.

As of May 31, 2025, a hypothetical 100-basis point increase/decrease in our variable interest rate on our borrowings would result in an interest expense increase/decrease of $5.1 million and $5.1 million, respectively, over the next twelve months.

ITEM 4. CONTROLS AND PROCEDURES

Management’s Evaluation of Disclosure Controls and Procedures

The term “disclosure controls and procedures” is defined in Exchange Act Rules 13a-15(e) and 15d-15(e). This term refers to the controls and procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the SEC and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) as appropriate, to allow timely decisions regarding required disclosure. An evaluation was performed under the supervision and with the participation of the Company’s management, including the CEO and CFO, of the effectiveness of the Company’s disclosure controls and procedures as of May 31, 2025. Based on that evaluation, the Company’s management, including the CEO and CFO, concluded that the Company’s disclosure controls and procedures were effective as of May 31, 2025.

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f), that occurred during the quarter ended May 31, 2025, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

WHEREAS the Company and the Trustee entered into an Indenture, dated as of July 18, 2023 (the “Base Indenture”), as supplemented by the Guarantee Supplemental Indenture, dated as of July 18, 2024 (together with the Base Indenture, the “Indenture”), among the Company, Aircastle (Ireland) Designated Activity Company, as a guarantor (the “Existing Subsidiary Guarantor”), and the Trustee, providing for the issuance of the Company’s 6.500% Senior Notes due 2028 (the “Notes”);

WHEREAS in connection with the New Subsidiary Guarantor’s guarantee of the Company’s (i) Seventh Amended and Restated Credit Agreement, dated as of February 8, 2024 (as may be amended, supplemented or otherwise modified from time to time), by and among the Company, the several lenders from time to time party thereto, and Citibank N.A., (ii) Second Amended and Restated Credit Agreement, dated as of January 31, 2024 (as may be amended, supplemented or otherwise modified from time to time), by and among the Company, the several lenders from time to time party thereto, and Mizuho Marubeni Leasing America Corporation, in its capacity as agent, (iii) Credit Agreement, dated as of February 28, 2023 (as may be amended, supplemented or otherwise modified from time to time), by and among the Company, the several lenders from time to time party thereto, and Mizuho Bank, Ltd, in its capacity as agent,

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the New Subsidiary Guarantor, the Company and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders as follows:

DEFINITIONS

Section 1.1. Defined Terms. As used in this Guarantee Supplemental Indenture, terms defined in the Base Indenture are used herein as therein defined, as applicable.

ARTICLE II

NOTE GUARANTEE

Section 2.1. Guarantee. (a) Subject to this Article 2, the New Subsidiary Guarantor hereby agrees, jointly and severally with the Existing Subsidiary Guarantor, to unconditionally guarantee to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Guarantee Supplemental Indenture, the Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: (a) the principal of and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the New Subsidiary Guarantor will be obligated to pay the same immediately. The New Subsidiary Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The New Subsidiary Guarantor hereby agree that its obligations hereunder will be unconditional, irrespective of the validity, regularity or enforceability of the Notes, the Indenture or this Guarantee Supplemental Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of the New Subsidiary Guarantor. The New Subsidiary Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that the Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes, the Indenture and this Guarantee Supplemental Indenture.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the New Subsidiary Guarantor or any custodian, Trustee, liquidator or other similar official acting in relation to either the Company or the New Subsidiary Guarantor, any

2

amount paid by either to the Trustee or such Holder, the Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(d) The New Subsidiary Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. The New Subsidiary Guarantor further agrees that, as between the New Subsidiary Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 5 of the Base Indenture for the purposes of the Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 5 of the Base Indenture, such obligations (whether or not due and payable) will forthwith become due and payable by the New Subsidiary Guarantor for the purpose of the Note Guarantee. The New Subsidiary Guarantor will have the right to seek contribution from any non-paying Guarantor, if any, so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

Section 2.2. Limitation on Guarantor Liability. The Note Guarantee by the New Subsidiary Guarantor will be limited to an amount not to exceed the maximum amount that can be guaranteed by the New Subsidiary Guarantor without rendering the Note Guarantee voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

Section 2.3. The New Subsidiary Guarantor May Consolidate, etc. Only on Certain Terms. The New Subsidiary Guarantor may not consolidate, amalgamate or merge with or into or wind up into (whether or not New Subsidiary Guarantor is the surviving Person, another Person other than the Company or another Guarantor, if any), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions, to any Person unless:

(a)immediately after giving effect to such transaction, no Default or Event of Default exists; and

(b)either:

(1)the Person acquiring the assets in any such sale or disposition or the Person formed by or surviving any such consolidation, amalgamation or merger (the “Successor Entity”), if other than the New Subsidiary Guarantor or the Company, assumes all the obligations of the New Subsidiary Guarantor under this Guarantee Supplemental Indenture and the Note Guarantee pursuant to a supplemental indenture; or

(2)such sale or other disposition does not violate the applicable provisions of the Indenture.

In case of any such consolidation, amalgamation, merger, sale or conveyance and upon the assumption by the Successor Entity, by a supplemental indenture, of the Note Guarantee and the due and punctual performance of all of the covenants and conditions of the Indenture and this Guarantee Supplemental Indenture to be performed by the New Subsidiary Guarantor, such

3

Successor Guarantor will succeed to and be substituted for the New Subsidiary Guarantor with the same effect as if it had been named herein as the New Subsidiary Guarantor.

Except as set forth in Section 108 of the Base Indenture, and notwithstanding clauses (a) and (b) above, nothing contained in this Guarantee Supplemental Indenture, the Indenture or in any of the Notes will prevent any consolidation or merger of the New Subsidiary Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the

property of the New Subsidiary Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor. Upon any such consolidation or merger of the New Subsidiary Guarantor with or into another Guarantor or with or into the Company, the Note Guarantee of the New Subsidiary Guarantor that does not survive will no longer be of any force or effect.

Section 2.4. Note Guarantee Releases.In the event of a sale or other transfer or disposition of all of the Capital Stock in the New Subsidiary Guarantor to any Person that is not an Affiliate of the Company in compliance with the terms of the Indenture and this Guarantee Supplemental Indenture, or in the event all or substantially all the assets or Capital Stock of the New Subsidiary Guarantor are sold or otherwise transferred, by way of merger, amalgamation, consolidation or otherwise, to a Person that is not an Affiliate of the Company in compliance with the terms of the Indenture or this Guarantee Supplemental Indenture, then, without any further action on the part of the Trustee or any Holder, the New Subsidiary Guarantor (or the Person concurrently acquiring such assets of the New Subsidiary Guarantor) shall be deemed automatically and unconditionally cancelled, released and discharged of any obligations under the Note Guarantee, as evidenced by a supplemental indenture, written instrument or confirmation executed by the Trustee, upon request; provided, however that if evidence of such cancellation, discharge or release is requested to be executed by the Trustee, an Officers’ Certificate and an Opinion of Counsel complying with Section 102 of the Base Indenture. In addition, upon the release or discharge of any guarantee which resulted in the creation of a Note Guarantee (except a discharge or release by or as a result of payment under such guarantee), the New Subsidiary Guarantor shall be deemed automatically and unconditionally cancelled, released and discharged of any obligations under the Note Guarantee, as evidenced by a supplemental indenture, written instrument or confirmation executed by the Trustee, upon request.

NOTE GUARANTEE

Section 2.1. Guarantee. (a) Subject to this Article 2, the New Subsidiary Guarantor hereby unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Guarantee Supplemental Indenture, the Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, that: (a) the principal of and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuers to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the New Subsidiary Guarantor will be obligated to pay the same immediately. The New Subsidiary Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The New Subsidiary Guarantor hereby agree that its obligations hereunder will be unconditional, irrespective of the validity, regularity or enforceability of the Notes, the Indenture or this Guarantee Supplemental Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of the New Subsidiary Guarantor. The New Subsidiary Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever and covenants that the Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes, the Indenture and this Guarantee Supplemental Indenture.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Issuers, the New Subsidiary Guarantor or any custodian, Trustee, liquidator or other similar official acting in relation to either the Issuers or the New Subsidiary Guarantor, any amount paid by either to the Trustee or such Holder, the Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

2

(d) The The New Subsidiary Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. The New Subsidiary Guarantor further agrees that, as between the New Subsidiary Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 5 of the Indenture for the purposes of the Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 5 of the Indenture, such obligations (whether or not due and payable) will forthwith become due and payable by the New Subsidiary Guarantor for the purpose of the Note Guarantee. The New Subsidiary Guarantor will have the right to seek contribution from any non-paying Guarantor, if any, so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

Section 2.2. Limitation on Guarantor Liability. The Note Guarantee by the New Subsidiary Guarantor will be limited to an amount not to exceed the maximum amount that can be guaranteed by the New Subsidiary Guarantor without rendering the Note Guarantee voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

Section 2.3. The New Subsidiary Guarantor May Consolidate, etc. Only on Certain Terms. The New Subsidiary Guarantor may not consolidate, amalgamate or merge with or into or wind up into (whether or not New Subsidiary Guarantor is the surviving Person, another Person other than an Issuer or another Guarantor, if any), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions, to any Person unless:

(a)immediately after giving effect to such transaction, no Default or Event of Default exists; and

(b)either:

(1)the Person acquiring the assets in any such sale or disposition or the Person formed by or surviving any such consolidation, amalgamation or merger (the “Successor Entity”), if other than the New Subsidiary Guarantor or the Company, assumes all the obligations of the New Subsidiary Guarantor under this Guarantee Supplemental Indenture and the Note Guarantee pursuant to a supplemental indenture; or

(2)such sale or other disposition does not violate the applicable provisions of the Indenture.

In case of any such consolidation, amalgamation, merger, sale or conveyance and upon the assumption by the Successor Entity, by a supplemental indenture, of the Note Guarantee and the due and punctual performance of all of the covenants and conditions of the Indenture and this Guarantee Supplemental Indenture to be performed by the New Subsidiary Guarantor, such Successor Guarantor will succeed to and be substituted for the New Subsidiary Guarantor with the same effect as if it had been named herein as the New Subsidiary Guarantor.

3

Except as set forth in Section 108 of the Indenture, and notwithstanding clauses (a) and (b) above, nothing contained in this Guarantee Supplemental Indenture, the Indenture or in any of the Notes will prevent any consolidation or merger of the New Subsidiary Guarantor with or into an Issuer or another Guarantor, or will prevent any sale or conveyance of the property of the New Subsidiary Guarantor as an entirety or substantially as an entirety to an Issuer or another Guarantor. Upon any such consolidation or merger of the New Subsidiary Guarantor with or into another Guarantor or with or into an Issuer, the Note Guarantee of the New Subsidiary Guarantor that does not survive will no longer be of any force or effect.

Section 2.4. Note Guarantee Releases.In the event of a sale or other transfer or disposition of all of the Capital Stock in the New Subsidiary Guarantor to any Person that is not an Affiliate of an Issuer in compliance with the terms of the Indenture and this Guarantee Supplemental Indenture, or in the event all or substantially all the assets or Capital Stock of the New Subsidiary Guarantor are sold or otherwise transferred, by way of merger, amalgamation, consolidation or otherwise, to a Person that is not an Affiliate of an Issuer in compliance with the terms of the Indenture or this Guarantee Supplemental Indenture, then, without any further action on the part of the Trustee or any Holder, the New Subsidiary Guarantor (or the Person concurrently acquiring such assets of the New Subsidiary Guarantor) shall be deemed automatically and unconditionally cancelled, released and discharged of any obligations under the Note Guarantee, as evidenced by a supplemental indenture, written instrument or confirmation executed by the Trustee, upon request; provided, however that if evidence of such cancellation, discharge or release is requested to be executed by the Trustee, an Officers’ Certificate and an Opinion of Counsel complying with Section 102 of the Indenture. In addition, upon the release or discharge of any guarantee which resulted in the creation of a Note Guarantee (except a discharge or release by or as a result of payment under such guarantee), the New Subsidiary Guarantor shall be deemed automatically and unconditionally cancelled, released and discharged of any obligations under the Note Guarantee, as evidenced by a supplemental indenture, written instrument or confirmation executed by the Trustee, upon request.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Organization

Aircastle Limited (“Aircastle,” the “Company,” “we,” “us” or “our”) is a Bermuda company that was incorporated on October 29, 2004, under the provisions of Section 14 of the Companies Act of 1981 of Bermuda. Aircastle’s business is acquiring, leasing, managing and selling commercial jet aircraft.

The Company is controlled by affiliates of Marubeni Corporation (“Marubeni”) and Mizuho Leasing Company, Limited (“Mizuho Leasing” and, together with Marubeni, our “Shareholders”).

Aircastle is a holding company and conducts its business through subsidiaries that are wholly owned, either directly or indirectly, by Aircastle.

Basis of Presentation and Principles of Consolidation

The consolidated financial statements presented are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”).

The accompanying consolidated financial statements are unaudited and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial reporting and, in our opinion, reflect all adjustments, including normal recurring items, which are necessary to present fairly the results for interim periods. Operating results for the periods presented are not necessarily indicative of the results that may be expected for the entire year. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been omitted in accordance with the rules and regulations of the SEC. However, we believe that the disclosures are adequate to make the information presented not misleading. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended February 28, 2025.

The consolidated financial statements include the accounts of Aircastle and all its subsidiaries, including any Variable Interest Entity (“VIE”) of which Aircastle is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation.

We manage and analyze our business and report our results of operations based on one operating and reportable segment: leasing, financing, selling and managing commercial flight equipment. Our Chief Executive Officer is the chief operating decision maker (the “CODM”). As a single reportable segment entity, the CODM utilizes consolidated net income to evaluate segment performance and allocate resources. The significant segment expenses and other segment items, such as total assets, that are provided to the CODM align with expense information that is included in the Company’s consolidated balance sheets and statements of income.

The Company’s management has reviewed and evaluated all events or transactions for potential recognition and/or disclosure subsequent to the balance sheet date of May 31, 2025, through the date on which the consolidated financial statements included in this Form 10-Q were issued.

Risk and Uncertainties

In the normal course of business, Aircastle encounters several significant types of economic risk, including credit, market, aviation industry and capital market risks. Credit risk is the risk of a lessee’s inability or unwillingness to make contractually required payments and to fulfill its other contractual obligations to Aircastle. Market risk reflects the change in the value of financings due to changes in interest rate spreads or other market factors, including the value of collateral underlying financings. Aviation industry risk is the risk of a downturn in the commercial aviation industry which could adversely impact a lessee’s ability to make payments, increase the risk of early lease terminations and depress lease rates and the value of the Company’s aircraft. 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.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. While Aircastle believes the estimates and related assumptions used in the preparation of the consolidated financial statements are appropriate, actual results could differ from those estimates.

Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASC 740”). ASC 740 enhances the transparency of income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The standard requires disclosure of specific categories in the rate reconciliation, using both percentages and reporting currency amounts, as well as disclosure of income taxes paid, net of refunds received, disaggregated by federal, state, and foreign taxes and individual jurisdictions. The standard is effective for annual periods beginning after December 15, 2024, and will be adopted by the Company for the year ended February 28, 2026. The amendments in ASU 2023-09 should be applied on a prospective basis; however, retrospective application to all prior periods presented in the annual financial statements is permitted. The Company does not anticipate that the adoption of the standard will have a material impact on our consolidated financial statements.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This standard requires entities to provide additional disclosure around certain costs and expenses presented within the Income Statement. This standard aims to improve the disclosures around the entity’s expenses and address requests from investors for more detailed information about the types of expenses. The standard is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The Company does not anticipate that the adoption of the standard will have a material impact on its consolidated financial statements or related disclosures.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Fair value measurements and disclosures require the use of valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs.

Assets Measured at Fair Value on a Recurring Basis

The following tables set forth our financial assets as of May 31, 2025 and February 28, 2025, that we measured at fair value on a recurring basis by level within the fair value hierarchy. Assets measured at fair value are classified in their entirety based on the lowest level of input that is significant to their fair value measurement.

			Fair Value Measurements at May 31, 2025 Using Fair Value Hierarchy
	Fair Value as of May 31, 2025		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Valuation Technique
Assets:
Cash and cash equivalents	$	223,230	$	223,230	$	—	$	—	Market
Investments, at fair value:
Investment in debt securities	$	5,029	$	—	$	—	$	5,029	Income
Investment in equity securities	5,340		1,442		—		3,898		Market/Income
Total investments, at fair value	$	10,369	$	1,442	$	—	$	8,927

			Fair Value Measurements at February 28, 2025 Using Fair Value Hierarchy
	Fair Value as of February 28, 2025		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Valuation Technique
Assets:
Cash and cash equivalents	$	279,052	$	279,052	$	—	$	—	Market
Investments, at fair value:
Investment in debt securities	$	5,029	$	—	$	—	$	5,029	Income
Investment in equity securities	4,883		985		—		3,898		Market/Income
Total investments, at fair value	$	9,912	$	985	$	—	$	8,927

Our cash and cash equivalents consist largely of money market securities that are highly liquid and easily tradable. These securities are valued using inputs observable in active markets for identical securities (Level 1). Our investments in debt and equity securities consist of notes and shares received as a result of claims settlements from various airline customers that had entered into bankruptcy proceedings or similar-type restructurings. Our investment in equity securities that are traded in an active market have been valued using quoted market prices (Level 1). Our investments in other equity securities and debt securities for which there is no active market or there is limited market data have been valued using the income approach (Level 3).

For the three months ended May 31, 2025, we had no transfers into or out of Level 3.

Assets Measured at Fair Value on a Non-recurring Basis

We measure the fair value of certain assets and liabilities on a non-recurring basis, when U.S. GAAP requires the application of fair value, including events or changes in circumstances that indicate the carrying amounts of these assets may not be recoverable. Assets subject to these measurements include our aircraft and unconsolidated equity method investment.

We record aircraft at fair value when we determine the carrying value may not be recoverable. Fair value measurements for aircraft in impairment tests are based on the average of the market approach (Level 2 or 3), which includes third-party appraisal data, and an income approach (Level 3), which includes the Company’s assumptions and appraisal data as to the present value of future cash proceeds from leasing and selling aircraft. Level 3 valuations contain significant non-observable inputs. See “Aircraft Valuation” below for further information.

We account for our unconsolidated equity method investment under the equity method of accounting. Our investment is recorded at cost and is adjusted by undistributed earnings and losses and the distributions of dividends and capital. This investment is reviewed for impairment whenever events or changes in circumstances indicate the fair value is less than its carrying value and the decline is other-than-temporary.

Financial Instruments

Our financial instruments, other than cash, consist principally of cash equivalents, accounts receivable, investments in debt and equity securities, accounts payable and secured and unsecured financings. The fair value of cash and cash equivalents, accounts receivable and accounts payable approximates the carrying value of these financial instruments because of their short-term nature.

The fair value of our investments, which consist of debt and equity securities, have been valued using either quoted market prices to the extent such securities are traded in an active market (Level 1), or using the income approach for those securities where there is no active market or there is limited market data (Level 3). The fair value of our senior notes is estimated using quoted market prices (Level 1), whereas all our other financings are valued using a discounted cash flow analysis, based on our current incremental borrowing rates for similar types of borrowing arrangements (Level 2).

The carrying amounts and fair values of our financial instruments at May 31, 2025 and February 28, 2025, were as follows:

	May 31, 2025				February 28, 2025
Assets	Carrying Amount of Asset		Fair Value of Asset		Carrying Amount of Asset		Fair Value of Asset
Investments, at fair value(1)	$	10,369	$	10,369	$	9,912	$	9,912
Other investments, net	728		728		4,916		4,916
Liabilities	Carrying Amount of Liability		Fair Value of Liability		Carrying Amount of Liability		Fair Value of Liability
Credit Facilities	$	20,000	$	20,000	$	150,000	$	150,000
Secured Term Financings	116,663		108,886		509,104		513,161
Unsecured Term Financings	600,000		600,000		—		—
Senior Notes	4,350,000		4,349,387		4,350,000		4,387,341

Aircraft Valuation

Impairment of Flight Equipment

During the three months ended May 31, 2025, the Company recorded transactional impairment charges totaling $5.1 million related to engine redeliveries and 1 aircraft lease termination. The Company recognized $18.7 million of revenue related to maintenance, security deposits, and the reversal of lease incentive liabilities for these engines and aircraft during the three months ended May 31, 2025.

Recoverability Assessment

We perform a recoverability assessment of all our aircraft and other flight equipment on a quarterly basis and annually during the third quarter of each fiscal year.

We perform a recoverability test when events or changes in circumstances, or indicators, suggest that the carrying amount or net book value of an aircraft or other flight equipment may not be recoverable. For assets with indicators of impairment, we measure whether the estimated future undiscounted net cash flows expected to be generated by the asset exceed its net book value. The undiscounted cash flows consist of cash flows from currently contracted lease rentals and maintenance payments, future projected lease rates and maintenance payments, transition costs, estimated down time, and estimated residual or scrap values for an aircraft. In the event that an aircraft does not meet the recoverability test, the aircraft will be adjusted to fair value, resulting in an impairment charge.

Management assumptions are based on current and future expectations of the global demand for a particular aircraft type and historical experience in the aircraft leasing market and aviation industry, as well as information received from third-party industry sources. The factors considered in estimating the undiscounted cash flows are impacted by changes in future periods due to changes in projected lease rental and maintenance payments, residual values, economic conditions, technology, airline demand for a particular aircraft type and other factors, such as the location of the aircraft and accessibility to records and technical documentation.

If our estimates or assumptions change, including those related to our customers that have entered judicial insolvency proceedings or similar-type proceedings or restructurings, we may revise our cash flow assumptions and record future impairment charges. While we believe that the estimates and related assumptions used in our recoverability assessments are appropriate, actual results could differ from those estimates.

Update on Russian Aircraft

The Company leased 9 aircraft to Russian airlines that were unrecoverable following Russia’s invasion of Ukraine in February 2022. The Company filed claims against the reinsurers of the Russian airlines’ insurance and the Company’s contingent and possessed insurance policies (“C&P Policies”) seeking indemnity.

During the years ended February 28, 2025 and February 29, 2024, the Company received aggregate cash settlement proceeds of $92.7 million in settlement of certain of the Company’s claims under the Russian airlines’ insurance and the Company’s C&P Policies.

The receipt of the insurance proceeds serve to mitigate, in part, the Company’s losses under its aviation insurance policies. The Company remains in settlement discussions with some of the remaining insurers under its C&P Policies. However, the collection, timing and amount of any future recoveries, including those related to insurance litigation, remain uncertain. Accordingly, at this time, the Company can give no assurance as to when or what amounts it may ultimately collect with respect to these matters.

Subsequent to May 31, 2025, the Company entered into a settlement agreement with certain additional C&P insurers for an aggregate settlement amount of $14.7 million, which will be recognized in its consolidated statement of income in the second quarter of 2025.

Unsecured Debt Financings

Unsecured Term Loan

On April 28, 2025, Aircastle Advisor, LLC (“AALLC”), a wholly-owned subsidiary of the Company, entered into a credit agreement with the lender parties thereto (the “Unsecured Term Loan Credit Agreement”) providing for a $600.0 million unsecured term loan (the “Unsecured Term Loan”). The Unsecured Term Loan bears interest at a floating rate under the Term Secured Overnight Funding Rate (“SOFR”) (as defined in the Unsecured Term Loan Credit Agreement) plus 1.40% per annum and matures on April 28, 2030. Prior to April 28, 2026, the total credit commitment under the

Unsecured Term Loan can be increased up to a maximum amount of $700.0 million. The Unsecured Term Loan Credit Agreement contains, among other customary provisions, a $1.1 billion minimum net worth covenant, a 2.0:1.0 minimum interest coverage ratio covenant, and a 1.25:1.0 minimum unencumbered asset ratio. The Company and Aircastle (Ireland) Designated Activity Company, a wholly-owned subsidiary of the Company, agreed to fully and unconditionally guarantee AALLC’s obligations under the Unsecured Term Loan Credit Agreement.

Revolving Credit Facilities

As of May 31, 2025, we had $20.0 million outstanding under our revolving credit facilities and had $2.1 billion available for borrowing.

As of May 31, 2025, we were in compliance with all applicable covenants in our financings.

AALLC Guarantees

In connection with AALLC entering into the Unsecured Term Loan Credit Agreement, AALLC agreed to fully and unconditionally guarantee (the “AALLC Guarantees”) the Company’s obligations under its: (i) revolving credit facilities; (ii) 5.250% Senior Notes due 2025; (iii) 4.250% Senior Notes due 2026; (iv) 2.850% Senior Notes due 2028; (v) 6.500% Senior Notes due 2028; (vi) 5.950% Senior Notes due 2029; (vii) 5.25% Senior Notes due 2030, and (viii) 5.75% Senior Notes due 2031 (collectively, the “Existing Unsecured Debt”). As a result of the AALLC Guarantees, the Unsecured Term Loan ranks pari passu in right of payment with the Existing Unsecured Debt.

Income taxes have been provided for based upon the tax laws and rates in countries in which our operations are conducted and income is earned. On December 18, 2023, the Government of Bermuda enacted the Bermuda Corporate Income Tax Act (the “Bermuda CIT Act”), which imposes a 15% corporate current income tax (the “Bermuda CIT”) effective for tax years beginning on or after January 1, 2025. Accordingly, the Company is subject to the Bermuda CIT with respect to its fiscal year beginning March 1, 2025, and subsequent years.

The sources of income from continuing operations before income taxes and earnings of our unconsolidated equity method investment for the three months ended May 31, 2025 and 2024, were as follows:

	Three Months Ended May 31,
	2025		2024
U.S. operations	$	10,090	$	4,996
Non-U.S. operations	51,525		14,138
Income from continuing operations before income taxes and earnings of unconsolidated equity method investment	$	61,615	$	19,134

Our U.S.-based aircraft-owning subsidiary is taxed in the United States. Our non U.S.-based aircraft-owning subsidiaries generally earn income from sources outside the United States and typically are not subject to U.S. federal, state or local income taxes.

We have a U.S.-based subsidiary which provides management services to our subsidiaries and is subject to U.S. federal, state and local income taxes. We also have Ireland and Singapore-based subsidiaries which provide management services to our non-U.S. subsidiaries and are subject to tax in those respective jurisdictions.

We recognized income tax provisions of $12.7 million and $3.6 million for the three months ended May 31, 2025 and 2024, respectively. Our effective tax rate for the three months ended May 31, 2025 and 2024, was 20.6% and 18.7%, respectively. The increase in our effective tax rate is primarily attributable to the mix of profits between the various jurisdictions in which we operate.

Ireland and Bermuda Tax Law Changes

On December 18, 2023, Ireland enacted Finance (No. 2) Bill 2023 (the “Finance Bill”) which includes legislative changes for new tax measures and amendments to the Irish tax code, such as provisions to implement the Pillar Two GloBE rules, new outbound payment rules, and a dividend withholding tax, among other changes. The Finance Bill did not have a significant impact on our consolidated financial statements for the three months ended May 31, 2025.

On December 18, 2023, Bermuda enacted the Bermuda CIT Act, which imposes the 15% Bermuda CIT that applies to Bermuda businesses that are part of multinational enterprise groups with annual revenue of €750 million or more and is effective for tax years beginning on or after January 1, 2025. The Company has appropriately considered the impact of the Bermuda CIT and its impact on current and deferred income taxes.

Accounting Policies [Abstract]

Organization

Organization

Aircastle Limited (“Aircastle,” the “Company,” “we,” “us” or “our”) is a Bermuda company that was incorporated on October 29, 2004, under the provisions of Section 14 of the Companies Act of 1981 of Bermuda. Aircastle’s business is acquiring, leasing, managing and selling commercial jet aircraft.

The Company is controlled by affiliates of Marubeni Corporation (“Marubeni”) and Mizuho Leasing Company, Limited (“Mizuho Leasing” and, together with Marubeni, our “Shareholders”).

Aircastle is a holding company and conducts its business through subsidiaries that are wholly owned, either directly or indirectly, by Aircastle.

Basis of Presentation and Principles of Consolidation

Basis of Presentation and Principles of Consolidation

The consolidated financial statements presented are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”).

The accompanying consolidated financial statements are unaudited and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial reporting and, in our opinion, reflect all adjustments, including normal recurring items, which are necessary to present fairly the results for interim periods. Operating results for the periods presented are not necessarily indicative of the results that may be expected for the entire year. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been omitted in accordance with the rules and regulations of the SEC. However, we believe that the disclosures are adequate to make the information presented not misleading. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended February 28, 2025.

The consolidated financial statements include the accounts of Aircastle and all its subsidiaries, including any Variable Interest Entity (“VIE”) of which Aircastle is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation.

We manage and analyze our business and report our results of operations based on one operating and reportable segment: leasing, financing, selling and managing commercial flight equipment. Our Chief Executive Officer is the chief operating decision maker (the “CODM”). As a single reportable segment entity, the CODM utilizes consolidated net income to evaluate segment performance and allocate resources. The significant segment expenses and other segment items, such as total assets, that are provided to the CODM align with expense information that is included in the Company’s consolidated balance sheets and statements of income.

The Company’s management has reviewed and evaluated all events or transactions for potential recognition and/or disclosure subsequent to the balance sheet date of May 31, 2025, through the date on which the consolidated financial statements included in this Form 10-Q were issued.

Risk and Uncertainties

Risk and Uncertainties

In the normal course of business, Aircastle encounters several significant types of economic risk, including credit, market, aviation industry and capital market risks. Credit risk is the risk of a lessee’s inability or unwillingness to make contractually required payments and to fulfill its other contractual obligations to Aircastle. Market risk reflects the change in the value of financings due to changes in interest rate spreads or other market factors, including the value of collateral underlying financings. Aviation industry risk is the risk of a downturn in the commercial aviation industry which could adversely impact a lessee’s ability to make payments, increase the risk of early lease terminations and depress lease rates and the value of the Company’s aircraft. 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.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. While Aircastle believes the estimates and related assumptions used in the preparation of the consolidated financial statements are appropriate, actual results could differ from those estimates.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASC 740”). ASC 740 enhances the transparency of income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The standard requires disclosure of specific categories in the rate reconciliation, using both percentages and reporting currency amounts, as well as disclosure of income taxes paid, net of refunds received, disaggregated by federal, state, and foreign taxes and individual jurisdictions. The standard is effective for annual periods beginning after December 15, 2024, and will be adopted by the Company for the year ended February 28, 2026. The amendments in ASU 2023-09 should be applied on a prospective basis; however, retrospective application to all prior periods presented in the annual financial statements is permitted. The Company does not anticipate that the adoption of the standard will have a material impact on our consolidated financial statements.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This standard requires entities to provide additional disclosure around certain costs and expenses presented within the Income Statement. This standard aims to improve the disclosures around the entity’s expenses and address requests from investors for more detailed information about the types of expenses. The standard is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The Company does not anticipate that the adoption of the standard will have a material impact on its consolidated financial statements or related disclosures.
