**Willis Lease Finance Corporation Prices Upsized Convertible Senior Notes Offering and** 

**Borrowed Common Stock Offering to Facilitate Hedging Transactions** 

**COCONUT CREEK, FL**, **May 13, 2026** – Willis Lease Finance Corporation (NASDAQ: WLFC) (the "Company"), the leading lessor of commercial aircraft engines and global provider of aviation services, announced today the pricing of its public offering (the "Notes Offering") of $200.0 million aggregate principal amount of 2.50% convertible senior notes due 2031 (the "Notes"), for total net proceeds of approximately $193.1 million, after deducting underwriting discounts and other estimated offering expenses. The offering size was increased from the previously announced offering size of $175.0 million. The Company also granted the underwriters of the Notes a 30-day option to purchase up to an additional $30.0 million principal amount of Notes, solely to cover over-allotments, if any. The Company currently intends to use the net proceeds from the issuance of the Notes to temporarily repay amounts outstanding under the Company's revolving credit facility until deployed for general corporate purposes. The Notes Offering is expected to close on May 18, 2026, subject to satisfaction of customary closing conditions.

Morgan Stanley & Co. LLC, BofA Securities and Deutsche Bank Securities Inc. are acting as joint book-running managers for the Notes Offering.

The Notes will be senior, unsecured obligations of the Company, will accrue interest payable semi-annually in arrears on May 15 and November 15 of each year, beginning on November 15, 2026, and will mature on May 15, 2031, unless earlier repurchased, redeemed or converted. Noteholders will have the right to convert their Notes in certain circumstances and during specified periods based on the applicable conversion rate. The Company will settle conversions of Notes by paying or delivering, as applicable, cash or a combination of cash and shares of its

------

common stock, at its election. The initial conversion rate is 3.7202 shares of common stock per $1,000 principal amount of Notes, which represents an initial conversion price of approximately $268.80 per share of common stock. The initial conversion price represents a premium of approximately 40.0% above the public offering price of the Company's common stock in the Concurrent Delta Offering described below.

The Notes will be redeemable, in whole or in part (subject to certain limitations), at the Company's option at any time, and from time to time, on or after May 21, 2029 and on or before the 41st scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of its common stock exceeds 130% of the conversion price for a specified period of time. The Company may not redeem less than all of the outstanding Notes unless the excess of the principal amount of the Notes outstanding as of the time the Company sends the related redemption notice over the aggregate principal amount of the Notes subject to such redemption is at least $75.0 million.

If a "fundamental change" (which will be defined in the indenture that will govern the Notes to include certain change-of-control events and the delisting of the Company's common stock) occurs, then, subject to a limited exception, noteholders may require the Company to repurchase their Notes at a cash repurchase price equal to the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date.

Concurrently with the Notes Offering, Morgan Stanley & Co. LLC, acting on behalf of itself and/or its affiliates (in such capacity, the "delta underwriter") is offering and selling short, in a separate, underwritten public offering under the Act, 281,250 shares of the Company's common stock to be borrowed from non-affiliate third parties to facilitate hedging transactions by certain investors subscribing for the Notes (the "Concurrent Delta Offering"). The delta underwriter will initially offer the shares of the Company's common stock directly to the public at a price of $192.00 per share of the Company's common stock and may subsequently offer the shares of the Company's Common Stock for sale in one or more transactions on the Nasdaq Global Market, in the over-the-counter market, through negotiated transactions or otherwise, at market prices prevailing at the time of sale, at prices related to prevailing market prices at the time of sale, at prices related to prevailing market prices or at negotiated prices. No new shares of the Company's common stock will be issued, and the Company will not receive the proceeds from the short sale of its common stock. The Concurrent Delta Offering is scheduled to close on May 18, 2026, subject to customary closing conditions.

The Concurrent Delta Offering and Notes Offering are contingent upon one another.

The Notes Offering will be made pursuant to an effective shelf registration statement filed with the U.S. Securities and Exchange Commission (the "SEC") on May 15, 2025 (the "Registration Statement") and a prospectus supplement. The Notes Offering will be made only by means of a prospectus supplement and an accompanying prospectus. The Concurrent Delta Offering will be made pursuant to the Registration Statement and a prospectus supplement. The Concurrent
