Willis Lease Finance Corporation shares climbed 35.3% over the past six months, outpacing the industry’s 21.8% growth and outperforming peers such as Air Lease (7.2%) and Ryder (18%). This rally reflects sustained aviation supply-demand imbalances and firm lease rates underpinning recurring cash flows.

In December 2025, the company formed a $600 million engine loan partnership with Liberty Mutual Investments. In January 2026, it launched a strategic engine leasing collaboration with Blackstone Credit & Insurance targeting over $1 billion in deployments over two years, diversifying funding and boosting fee income.

In the third quarter of 2025, lease rent revenues rose to $76.6 million while maintenance reserve revenues reached $76.1 million, driven by strong engine utilization and spare parts demand. Recent in-house initiatives, including a core engine restoration and a CFM56 life-extension program, are enhancing margins and lifecycle management.

Rising financing costs and higher leverage lifted net interest expense, while $10.2 million of equipment write-downs and accelerated depreciation weighed on margins. Trading at 5.02X trailing EV/sales versus an industry average of 7.4X indicates the stock remains attractively valued despite these headwinds.
