Willis Lease Finance Corporation Partners with CFM International on Program

to Extend Operational Life of CFM56 Engines

COCONUT CREEK, FL, February 9, 2026 - Willis Lease Finance Corporation (NASDAQ: WLFC) ("WLFC" or the "Company"), the leading lessor of commercial aircraft engines and a global provider of aviation services, announces the establishment of an industry-first program developed in collaboration with CFM International, ("CFM") with the goal of extending the operational life of CFM56-5B and CFM56-7B engines.

The program enables WLFC to keep CFM56-5B and CFM56-7B engines in service longer by restoring core components rather than fully disassembling the engine. WLFC is the first commercial aircraft engine lessor to partner with the OEM on this type of initiative for CFM56-5B and CFM56-7B engines, reflecting the Company's commitment to extending engine lifecycles.

"This program represents a meaningful evolution in how we manage engine assets," said Austin C. Willis, Chief Executive Officer of Willis Lease Finance Corporation. "By using this program to perform shop visits in our own shops as well as others, we expect to offer our customers a high quality product at a reasonable price."

"With this agreement, WLFC will benefit from OEM material to service their CFM56 engines," said Gaël Méheust, President and CEO of CFM International. "CFM56 engines have set standards for reliability and time on wing-benefits which this contract will extend well into the future for WLFC's customers."

WLFC has identified and inducted an initial group of engines for participation and will seek to grow it across additional assets over time.
