From a valuation perspective, Willis Lease Finance Corporation WLFC stock looks attractive. WLFC is currently trading at a trailing 12-month enterprise value/sales (EV/sales) of 4.36X, a roughly 37% discount compared with the industry average of 6.91X.
Though WLFC’s cheap valuation may present a potentially profitable opportunity for investors seeking value, a more comprehensive analysis is needed to determine if its discounted valuation is justified based on its fundamentals and growth prospects.

Business Tailwinds for WLFC
WLFC continues to benefit from favorable aviation leasing conditions, supported by fleet growth, aircraft delivery delays and constrained maintenance capacity. In the first half of 2026, lease rent revenue rose 10.4% year over year to $154.5 million, while total revenues increased 9.9% to $388.4 million. Maintenance services revenue advanced 37.7% to $18.8 million, and management and advisory fees nearly tripled to $13.4 million. The company’s commitment to acquire 27 additional LEAP-1A and 15 LEAP-1B engines through 2030 should further strengthen its exposure to high-demand next-generation assets.
Willis Aviation Capital is expanding WLFC beyond a traditional balance-sheet leasing model by bringing institutional capital into the platform. Assets under management reached about $4.4 billion as of June 30, 2026, up 21% year over year. The Liberty Mutual partnership is expected to invest up to $600 million in aircraft-engine financings, while the Blackstone partnership targets more than $1 billion of leasing assets. These funds create recurring management and advisory fees, expand origination capacity and allow WLFC to scale transaction volumes without funding every asset itself.
WLFC continues to deploy capital into aviation assets that can be monetized across leasing, trading, technical and aftermarket channels. In June, the company acquired three Airbus A330-300 aircraft for long-term lease to China Airlines and EVA Air. It then closed the acquisition of another 12 commercial aircraft and 13 engines in August. The larger portfolio should increase the asset base available for lease income while creating opportunities for maintenance, asset management and end-of-life services.
Rising global engine-maintenance demand is creating another tailwind for WLFC’s vertically integrated services platform. The company signed a five-year agreement with Pratt & Whitney to provide storage and lease-return services for several engine families, expanding its aftermarket relationship with a major OEM. WLFC is also developing its third Willis Engine Repair Center in Johor, Malaysia, with completion anticipated in the first quarter of 2027. The facility extends its repair model into Asia-Pacific, adds in-house restoration capacity and should improve its ability to service both owned engines and third-party assets closer to customers.
WLFC’s first-half adjusted EBITDA advanced 11.5% year over year to $244.6 million, while income from operations rose 29.9% to $67.8 million. With net debt to equity at 2.78 times and management highlighting incremental borrowing capacity for portfolio growth, WLFC has multiple avenues to finance acquisitions and expand its asset-management platform.
Headwinds for WLFC’s Business
Willis Lease Finance faces headwinds from softer short-term maintenance reserve revenues, which fell 14% year over year in the first half of 2026 amid fuel-price effects and fewer engines on short-term lease conditions. Spare-parts and equipment sales also declined. Meanwhile, higher G&A, technical and finance costs are adding pressure, driven by legal and strategic spending, increased engine-repair activity and refinancing-related losses. Geopolitical disruptions and interest-rate shifts remain additional risks for WLFC.
Conclusion
WLFC benefits from favorable aviation leasing conditions, fleet expansion, constrained engine supply and maintenance capacity, rising aftermarket demand, growing institutional partnerships and a larger asset portfolio, supporting higher lease revenues, fee income and earnings. However, softer maintenance reserve revenues and parts sales, along with rising G&A, technical and finance costs, will likely put pressure on performance.
WLFC’s undervaluation, despite the rise in share price, presents a lucrative opportunity for investors to add the stock to their portfolio.
