Item 2.01 Completion of Acquisition or Disposition of Assets.

On August 24, 2026, Willis Dallas Ltd. (the “Purchaser”), a Cayman Islands exempted company and wholly owned subsidiary of Willis Lease Finance Corporation, a Delaware corporation (the “Company”), completed the previously announced acquisition of the entire issued share capital of WNG II Aircraft Leasing (Cayman) Ltd. (the “Cayman Company”) from WNG International Master Fund II, L.P., a Cayman Islands exempted limited partnership (the “Cayman Seller”), and 100% of the issued and outstanding limited liability company interests of WNG Aircraft Management 3, LLC (the “US Company” and, together with the Cayman Company and their respective subsidiaries, the “Target Companies”) from WNG II Aircraft Management (Delaware), LLC, a Delaware limited liability company (the “US Seller” and, together with the Cayman Seller, the “Sellers”) (collectively, the “Acquisition”). The Acquisition was completed pursuant to a Purchase and Sale Agreement (the “Purchase Agreement”), dated as of July 10, 2026, as amended by that certain Amendment No. 1 thereto, dated as of August 24, 2026, by and among the Purchaser, the Cayman Seller, the US Seller, and, solely for the limited purposes set forth therein, the Company. The US Company and the Cayman Company, through the Cayman Company’s subsidiaries (including two Irish designated activity companies and various asset-owning companies), hold a portfolio of twelve (12) commercial aircraft and thirteen (13) spare aircraft engines (the “Portfolio”).

As previously disclosed, the base purchase price for the Acquisition was $379,300,000, which amount was adjusted downward to take into account basic rent received, maintenance reserves received, cash security deposits and other revenue received from and after an agreed upon historical economic closing date. The purchase price was subject to certain other adjustments calculated beginning on an agreed historical economic closing date, including (i) a reduction for any asset that suffers a total loss or that was removed, sold or otherwise disposed of prior to closing pursuant to pre-agreed arrangements in an amount equal to the consideration amount allocated to such asset (or, in the case of certain sold or disposed assets, the greater of such allocated amount and the applicable third-party sale price), (ii) an upward adjustment for interest accruing at a rate of 6.25% per annum from the historical economic closing date through closing, and (iii) other commercially agreed purchase price adjustments, the exact amount of which was determined based on the timing of the closing date (as so adjusted, the “Adjusted Purchase Price”). At closing, the Adjusted Purchase Price was approximately $262,900,000 and was paid to Sellers after further adjusting for the following amounts: (a) less a previously funded $10,000,000 deposit that will be released to Sellers in connection with closing, (b) less a $1,517,200 holdback amount that will be held for nine months to cover pre-closing leakage that was not deducted from the purchase price at closing, (c) less the amount required to discharge the Target Companies’ indebtedness under an existing credit facility, and (d) plus reimbursement of certain prepaid vendor costs.

The foregoing summary of the Purchase Agreement does not purport to be a complete description and is subject to and qualified in its entirety by reference to the full text of the Purchase Agreement, which will be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for the quarter ending September 30, 2026.

As previously disclosed, in connection with the Acquisition, the Company intends to allocate ten (10) of the acquired aircraft engines and six (6) of the acquired aircraft to subsidiaries of joint ventures of, or investment vehicles managed by, the Company.

Item 7.01 Regulation FD Disclosure.

On August 25, 2026, the Company issued a press release (the “Press Release”) regarding the matters described in Item 2.01 of this Current Report on Form 8-K, a copy of which is filed as Exhibit 99.1 and incorporated into this Item 7.01 by reference.

The information furnished pursuant to this Item 7.01, including Exhibit 99.1, shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to liabilities under that section, and shall not be deemed to be incorporated by reference into any filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act, unless specifically identified therein as being incorporated therein by reference.

We use words such as anticipates, believes, expects, future, intends, and similar expressions to identify forward-looking statements.

Willis Lease Finance Corporation Closes Transaction to Acquire Commercial Aircraft and Aircraft Engine Portfolio

Acquisition expands WLFC’s lease portfolio by an additional 12 aircraft and 13 engines

COCONUT CREEK, FL, August 25, 2026 – Willis Lease Finance Corporation (NASDAQ: WLFC) (the “Company” or “WLFC”), the leading lessor of commercial aircraft engines and global provider of aviation services, today announced that it has closed the transaction to acquire 12 commercial aircraft and 13 aircraft engines.

The acquisition expands WLFC’s aviation asset portfolio and provides additional opportunities to leverage the Company’s integrated leasing, asset management, technical and aftermarket capabilities. WLFC’s global platform provides multiple avenues to deploy and manage these assets with the objective of maximizing utilization and value throughout their lifecycle.

“We believe this acquisition represents an attractive opportunity to put capital to work in assets that fit well with our existing business,” said Austin C. Willis, Chief Executive Officer of WLFC. “It builds on our core strengths in aircraft and engine leasing and reflects our continued focus on disciplined growth and long-term value creation.”

Milbank LLP served as legal counsel to WLFC, and PricewaterhouseCoopers LLP provided accounting, tax, and financial due diligence services to WLFC in connection with the transaction. The seller was advised by Vedder as legal counsel and by KPMG Ireland as tax and accounting advisors in connection with the transaction.

Willis Lease Finance Corporation

Willis Lease Finance Corporation leases large and regional spare commercial aircraft engines and aircraft to airlines, aircraft engine manufacturers and maintenance, repair, and overhaul providers worldwide. These leasing activities are integrated with engine and aircraft trading, engine lease pools, and asset management services through Willis Mitsui & Co. Asset Management Limited, as well as various end-of-life solutions for engines and aviation materials provided through Willis Aeronautical Services, Inc. Through Willis Engine Repair Center®, Jet Centre by Willis, and Willis Aviation Services Limited, the Company’s service offerings include Part 145 engine maintenance, aircraft line and base maintenance, aircraft disassembly, parking and storage, airport FBO and ground and cargo handling services.

Except for historical information, the matters discussed in this press release contain forward-looking statements that involve risks and uncertainties. Do not unduly rely on forward-looking statements, which give only expectations about the future and are not guarantees. Forward-looking statements speak only as of the date they are made, and we undertake no obligation to update them to reflect any change in the Company’s expectations or any change in events, conditions, or circumstances on which the forward-looking statement is based, except as required by law.

The Company’s 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 war, terrorist activity and the COVID-19 pandemic; changes in oil prices, rising inflation and other disruptions to world markets; trends in the airline industry and the Company’s ability to capitalize on those trends, including growth rates of markets and other economic factors; risks associated with owning and leasing jet engines and aircraft; the Company’s ability to successfully negotiate equipment purchases, sales and leases, to collect outstanding amounts due and to control costs and expenses; changes in interest rates and availability of capital, both to the Company and its customers; the Company’s ability to continue to meet changing customer demands; regulatory changes affecting airline operations, aircraft maintenance, accounting standards and taxes; the market value of engines and other assets in the Company’s portfolio; and risks detailed in the Company’s Annual Report on Form 10-K and other continuing and current reports filed with the Securities and Exchange Commission. It is advisable, however, to consult any further disclosures the Company makes on related subjects in such filings. These statements constitute the Company’s cautionary statements under the Private Securities Litigation Reform Act of 1995.
