What Willis Lease Finance does

Willis Lease Finance Corporation (NASDAQ: WLFC), founded in 1985 by Charles F. Willis IV, is the largest independent lessor of commercial aircraft jet engines, operating from its Coconut Creek, Florida headquarters with offices in Ireland, France, Singapore, the UK, and China and serving customers in 120+ countries. Its core operating model leases commercial aircraft engines (and increasingly whole aircraft) to airlines, cargo operators, MROs, OEMs, and other lessors through products including ConstantAccess® (on-demand engine availability), ConstantThrust® (maintenance cost/risk coverage that reportedly halves engine change costs), the Revolving Credit Lease (RCL), Green-time Lease, and the CFM56-7B Pooling Program. The company complements this with a vertically integrated services platform — Willis Engine Repair Center® (EASA/FAA Part 145 dual-release in Coconut Creek and Bridgend), Willis Module Shop™ (in-house module restoration launched Feb 2026), Willis Aviation Services Limited (UK Part 145 maintenance and FBO at Teesside), and Willis Aeronautical Services (parts) — plus two joint ventures: Willis Mitsui & Co. Engine Support Limited (Dublin) and CASC Willis Engine Lease Company (Shanghai).

Revenue is generated primarily through subscription-like recurring lease rent (Q1 2026: $77.4M record) plus maintenance services (Q1 2026: $9.8M record), spare parts sales, aircraft disassembly/storage, and a newly launched asset management fee stream from Willis Aviation Capital. Pricing is quote-based and negotiated per transaction across short- and long-term lease structures. The asset base stood at $3.4B in owned and managed assets at the time of disclosure, supported by a $1.75B revolving credit facility (maturity 2031), $2.71B of total debt, and an active ABS program via Willis Engine Structured Trusts ($392.9M WEST IX in Dec 2025; $596M in Jun 2025; $410M WEST VII in 2023). FY2025 revenue reached a record $730M with Q1 2026 revenue of $194.35M (+23.2% YoY) and Q1 2026 adjusted EBITDA of $123.8M (+19.9% YoY); portfolio utilization rose to 86% from 80%.

The 2026 strategic agenda is dominated by capital scaling and platform extension: a $1B+ Blackstone Credit & Insurance partnership and a Liberty Mutual $600M credit strategy (both flowing through Willis Aviation Capital), an industry-first CFM56 lifecycle extension partnership with CFM International, the launch of Willis Module Shop™, an aircraft leasing buildout (A330-300 acquisition for China Airlines and EVA Air; new SVP Aircraft Leasing & Trading), Teesside facility expansion (50 acres plus two narrowbody hangars), and a 3-for-1 stock split approved in June 2026. Governance headwinds exist — over 92% of unaffiliated stockholders voted against executive compensation at the 2026 Annual Meeting, and an investigation into board fiduciary duties regarding executive pay (nearly doubling to $14.2M) is underway, alongside litigation against China Aircraft Leasing entities over a disputed engine.
