Willis Lease Finance combines a scarce-engine niche and $4.4 billion asset-management platform with attractive upside, but leverage, governance, and transactional revenue create a highly polarized risk/reward.
Overview
Willis Lease Finance is the premier independent lessor of commercial aircraft engines and APUs, serving airlines, cargo operators, OEMs, and MRO providers with spare engines, technical services, pools, records management, and storage. Its niche is supported by strict engine-maintenance requirements, aircraft delivery constraints, and high regulatory and technical barriers to entry. **The operating business is improving:** Q2 2026 revenue was $194.02 million, only 0.8% below the prior-year $195.50 million despite the absence of a large asset-sale gain; core operating income rose 20.2% to $34.00 million and Adjusted EBITDA increased 4.0% to $120.74 million. Diluted EPS of $1.31 beat the $0.92 consensus by 42.4%. **The strategic catalyst is Willis Aviation Capital**, now at $4.4 billion of assets under management, with $1.3 billion of discretionary capital still to deploy. At $54.18, the stock trades at 11.66x forward P/E, 1.68x book value, and 8.96x–9.78x TTM EV/EBITDA. The valuation is attractive relative to the growth opportunity, but 300% debt-to-equity, costly secured financing, insider selling, and severe governance concerns justify a discount. The report’s probability-weighted five-year target is $86.22.
