Record Quarterly Lease Rent Revenue

Reported in Willis Lease Finance Corporation’s First Quarter 2026 Financial Results

Declares Second Quarter 2026 Dividend of $0.40 Per Share

COCONUT CREEK, FL — May 5, 2026 — Willis Lease Finance Corporation (NASDAQ: WLFC) (“WLFC” or the “Company”), the leading lessor of commercial aircraft engines and global provider of aviation services, today announced its financial results for the first quarter ended March 31, 2026. The Company also announced a quarterly dividend of $0.40 per share of common stock outstanding. The dividend is expected to be paid on May 22, 2026 to shareholders of record at the close of business on May 11, 2026.

First Quarter 2026 Highlights (All metrics compared to first quarter 2025, except where noted)

•Quarterly total revenue of $194.3 million, an increase of 23.2%

•Income from operations of $33.8 million, an increase of 41.4%

•Quarterly pre-tax income of $36.8 million, an increase of 45.9%

•Diluted weighted average income per common share of $3.26, an increase of 47.5%

•Record high quarterly lease rent revenue of $77.4 million, an increase of 14.2%

•Record high quarterly maintenance services revenue of $9.8 million, an increase of 74.9%

•Gain on sale of leased equipment of $18.0 million, and increase of 304.8%

•Net income attributable to common shareholders of $23.7 million, an increase of 52.9%

•Adjusted EBITDA of $123.8 million, an increase of 19.9%

•Portfolio utilization increased to 85.8% at quarter end, compared to 79.9%

For the three months ended March 31, 2026, total revenue was $194.3 million, up 23.2% as compared to $157.7 million for the same period in 2025. For the first quarter of 2026, core lease rent and maintenance reserve revenues were $132.9 million in the aggregate, up 8.4% as compared to $122.6 million for the same period in 2025. The growth was predominantly driven by core lease and maintenance revenues associated with the continued strength of the aviation marketplace, as airlines leverage the Company’s extensive portfolio of in-demand engines as well as our parts and maintenance capabilities to avoid protracted, expensive engine shop visits.

“In the first quarter we outperformed nearly every revenue and earnings metric compared to Q1 2025,” said Austin Willis, CEO of WLFC, “and, thanks to the capital strategy we executed, we are poised for significant growth.”

First Quarter 2026 Operating Results

Lease rent revenue increased by $9.6 million, or 14.2%, to $77.4 million in the three months ended March 31, 2026 from $67.7 million for the three months ended March 31, 2025. The increase is due to an increase in the average size of the portfolio as compared to that of the prior year period as well as an increase in average utilization (based on net book value of equipment held for operating lease, maintenance rights, and notes receivable and investments in sales-type leases net of allowances) of equipment held in our operating lease portfolio.

During the first quarter of 2026, the Company recognized $12.4 million of long-term maintenance revenue, compared to $9.6 million for the quarter ended March 31, 2025. Long-term maintenance is recognized at the end of a lease period as the related maintenance reserve liability is released from the balance sheet.

For the quarter ended March 31, 2026, the gain on sale of leased equipment was $18.0 million, reflecting the sale of 14 engines from the lease portfolio. During the three months ended March 31, 2025, the Company sold seven engines, one airframe, and other parts and equipment for a net gain of $4.4 million.

In March 2026, the Company’s investment fund partnership with Liberty Mutual Investments commenced operations.

The book value of lease assets owned either directly or through WLFC’s joint ventures, inclusive of the Company’s equipment held for operating lease, maintenance rights, notes receivable, and investments in sales-type leases was $3,563.5 million as of March 31, 2026.

NON-GAAP FINANCIAL MEASURES

Adjusted EBITDA

We analyze our financial data to evaluate the health of our business and assess our performance. As appropriate, in addition to income or loss from operations under GAAP, we use Adjusted EBITDA, a non-GAAP financial measure, to evaluate our business. We believe that this non-GAAP financial measure provides meaningful supplemental information regarding our performance as it excludes certain items that may not be indicative of our recurring operating results. We also believe that investors, in addition to management, benefit from referring to this non-GAAP financial measure in assessing our performance, when viewed together with our GAAP results. While items excluded from Adjusted EBITDA may be recurring in nature and should not be disregarded in evaluating performance, it can be useful to exclude such items as they can vary significantly between periods and or not be indicative of current or future operating results.

Because non-GAAP financial measures are not standardized, our calculation of Adjusted EBITDA may differ from similarly titled non-GAAP measures, if any, reported by other companies. This non-GAAP financial measure should not be considered in insolation from, or as a substitute for, financial information performed in accordance with GAAP.

We define Adjusted EBITDA as net income attributable to common shareholders, excluding (i) income tax expense, (ii) interest expense, (iii) preferred stock dividends/costs, (iv) loss on debt extinguishment, (v) depreciation and amortization expense, (vi) stock compensation expense, (vii) write-down of equipment, (viii) acquisition, financing and divestitures related expenses, and (ix) other items not indicative of our ongoing operating performance.

Adjusted EBITDA was approximately $123.8 million and $103.3 million for the three months ended March 31, 2026 and 2025, respectively. See below for the reconciliation of Adjusted EBITDA to the most directly comparable GAAP measure, net income attributable to common shareholders.

2 DISCLAIMER Forward Looking Statements This presentation contains certain forward-looking statements within the meaning of the federal securities laws. Some of the forward-looking statements can be identified by the use of forward-looking words. Statements that are not historical in nature, including ‘‘anticipate,’’ ‘‘may,’’ ‘‘estimate,’’ ‘‘should,’’ ‘‘expect,’’ ‘‘plan,’’ ‘‘believe,’’ ‘‘intend,’’ and similar words, or the negatives of those words, are intended to identify forward-looking statements. They also include statements containing a projection of revenues, earnings (loss), capital expenditures, dividends, capital structure or other financial terms. Certain statements regarding the following particularly are forward- looking in nature:  Willis Lease Financial Corporation (the "Company" or "WLFC")’s business strategy;  WEST’s business strategy and assumptions used to develop the cash flow models;  future performance, developments, market forecasts or projections; and  WLFC’s projected capital expenditures. All forward-looking statements are based on our beliefs, assumptions and expectations of future economic performance, taking into account the information currently available. These statements are not statements of historical fact. Forward-looking statements are subject to a number of factors, risks and uncertainties, some of which are not currently known and many of which are beyond WLFC’s and WEST’s control, which may cause actual results, performance or financial condition to be materially different from the stated expectations of future results, performance or financial position, as well as those included in the cash flow models. Our actual results may differ materially from the results discussed in forward-looking statements. Factors that might cause such a difference include, but are not limited to:  the effects on the airline industry and the global economy of events such as terrorist activity;  changes in fuel prices and other disruptions to the world markets and the global economy of geopolitical, weather, cybersecurity, humanitarian and other events, including but not limited to war and terrorist activity;  trends in the airline industry, including growth rates of markets and other economic factors;  risks associated with owning and leasing commercial engines and aircraft;  changes in interest rates and availability of capital to us and to our customers;  our ability to continue to meet our customers’ changing demands;  the market value of engines and other assets in our portfolio;  regulatory changes affecting commercial aircraft operators, aircraft maintenance, engine standards, accounting standards and taxes; and  WLFC’s, in its capacity as Servicer, ability to successfully negotiate engine purchases, sales and leases, to collect outstanding amounts due, and to repossess engines under defaulted leases, and to control costs and expenses.  further information regarding these and other risks is included in WLFC's most recent U.S. Securities and Exchange Commission ("SEC") filings, including its Annual and Quarterly Reports on Forms 10-K and 10-Q, respectively, filed with the SEC under the heading “Risk Factors.” In light of these risks, uncertainties and assumptions, you are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date of presentation or as of the date of any document incorporated by reference, as applicable. Such forward-looking statements are inherently uncertain, and actual results may differ from expectations. We are not under any obligation, and we expressly disclaim any obligation, to update or alter any forward-looking statements, whether as a result of new information, future events or otherwise. Non-GAAP Financial Measures In this presentation, WLFC presents certain non-GAAP measures, including EBITDA, EBITDA Margin, Free Cash Flow and similar measures, which are not required by, or presented in accordance with, GAAP. While WLFC believes these are useful metrics, companies use these metrics for differing purposes and they are often calculated in ways that reflect the particular circumstances of those companies. You should exercise caution in comparing the non-GAAP metrics reported by us to such metrics or other similar metrics as reported by other companies. Our non-GAAP metrics have limitations as analytical tools, and you should not consider them in isolation. The non-GAAP financial information presented herein is provided in addition to, not as a substitute for, or superior to, financial measures calculated in accordance with GAAP and should not be considered as alternatives to any performance measures derived in accordance with GAAP. A reconciliation of EBITDA, a non-GAAP financial measure, to its most directly comparable GAAP measure, can be found on slide 17 of this presentation. The distribution of this presentation in certain jurisdictions may be restricted by law. Those persons into whose possession this presentation comes are required to inform themselves about and to observe any such restrictions. This presentation does not constitute an offer to any person or to the public generally to subscribe for or otherwise acquire any securities. This presentation has been prepared solely for informational purposes and is not intended to serve as the basis for any investment decision. Under no circumstances is this presentation or the information contained herein to be construed as a prospectus, offering memorandum or advertisement and neither any part of this written or oral presentation nor any information or statement contained herein or therein shall form the basis of or be relied upon in connection with any contract or commitment whatsoever.
