On May 11, 2026, Four Tree Island Advisory LLC urged the shareholders of Willis Lease Finance Corporation to vote against all proposals set forth in the Company?s 2026 Annual Meeting except the ratification of the independent auditor, citing concerns over Executive Chairman Charles Willis?s $52.1 million 2025 compensation, which it argues is unjustifiable given Company?s small market capitalization and weak total shareholder return, especially in comparison to far larger and better-performing Companies where compensation levels are lower relative to scale and performance. In addition, Four Tree Island highlighted that such pay would rank among the highest-paid CEOs despite Company significantly underperforming peers, and raised broader issues regarding governance, related party transactions, and whether the Board has exercised appropriate oversight, alleging that decisions have primarily benefited the Executive Chairman at the expense of minority stockholders. Further, Four Tree Island opposed the proposed Charter Amendment, including an increase in share capital and potential 3-for-1 stock split, warning of continued dilution and emphasizing that approval requires 80% shareholder support, thereby giving minority investors decisive influence, and called on stockholders to send a clear message of dissatisfaction, vote against the proposals, and communicate concerns directly to the Board ahead of the May 26, 2026 meeting.
