Willis Lease Finance Corporation Launches In-House Engine Module Restoration Capability, Willis Module Shop

Successful inaugural engine restoration demonstrates strong EGT margin recovery and supports fleet transition strategy

COCONUT CREEK, Fla., Feb. 12, 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, today announced the successful completion of its first core engine restoration at its U.S.-based Willis Engine Repair Center®. This new, in-house engine module restoration capability will be branded Willis Module Shop™.

The restoration of a CFM56-7B core engine module marks a key milestone in WLFC’s strategy to expand its internal technical and operational capabilities and validates the module shop concept. Post-maintenance testing of the inaugural module demonstrated strong exhaust gas temperature (EGT) margin recovery, reflecting the quality, precision and effectiveness of the class-leading restoration process.

As the aviation industry continues its transition from legacy to next-generation aircraft and engine platforms, this achievement further strengthens WLFC’s vertically integrated engine lifecycle offering. Willis Module Shop™ complements WLFC’s other programs like ConstantThrust® and ConstantAccess®, which enable customers worldwide to navigate fleet and engine asset transitions with confidence. Together, these capabilities provide reliable availability, predictable performance, disciplined core engine value restoration, improved asset utilization, cost efficiency and long-term portfolio returns.

“We have been doing module swaps and exchanges for years,” said Austin C. Willis, Chief Executive Officer of WLFC. “Bringing this core module restoration in-house allows us to further reduce maintenance expense both for ourselves and our customers, while enhancing our control, turnaround times and overall competitive advantage.”

WLFC continues to expand its aviation services platform, providing end-to-end support across the engine lifecycle, including leasing and trading, engine and aircraft MROs and disassembly, spare parts, consulting, and asset management.
