Willis Lease Finance has signed a five-year storage agreement with Pratt & Whitney covering engine storage and lease return services. The deal expands the company's aviation aftermarket capabilities and utilises its Coconut Creek and Bridgend facilities. The contract covers several widely used commercial engine families, positioning Willis Lease Finance alongside major aerospace groups such as General Electric and Rolls-Royce in engine services. The agreement enables the company to monetise existing infrastructure through contract-based work rather than relying solely on engine leasing. The stock currently trades at $71.33, up 59.6% year to date. Earnings grew 16.4% over the past year. The company trades at a P/E of 13x, below the US market P/E of 19.3x.

Four Tree Island Advisory, a top-10 shareholder in Willis Lease Finance Corporation, announced that proxy advisors ISS and Glass Lewis have recommended shareholders vote against director Stephen Jones's election and the company's executive compensation at the 26 May annual meeting. ISS cited "unmitigated pay-for-performance misalignment" and noted the chairman's base salary is "relatively high" with "outsized and discretionary" bonuses. Glass Lewis questioned "substantial one-off grants" to Charles Willis. Four Tree Island highlighted that whilst revenue grew 160% over five years, EBITDA increased only 89% and SG&A expenses rose 236%. The shareholder also noted Willis Lease underperformed competitor FTAI Aviation by approximately 431% and 629% over three- and five-year periods respectively. Four Tree Island urges shareholders to vote against all proposals except auditor ratification.
