Florida-based aviation lessor Willis Lease Finance Corporation (NASDAQ: WLFC) posted a 29.4% year-over-year revenue increase in the second quarter of 2025, reaching $195.5 million, according to its official earnings release on Monday. The growth was driven by higher demand for short-term engine leasing and expanded parts sales.

Lease rent and maintenance reserve revenue rose to $123 million, up from $118.8 million in Q2 2024. The company credited airlines’ preference for leasing engines over high-cost shop visits as a major contributor. With airlines facing ongoing supply chain delays and cost pressures, engine leasing remains a preferred strategy for cost efficiency.

Short-term maintenance revenues, primarily from non-reimbursable usage charges, also climbed, reaching $50.2 million, compared to $45.9 million last year. This increase was supported by both more engines under lease and adjustments in usage rate terms.

Sales of spare parts and equipment soared to $30.4 million, up from just $6.2 million in the same period last year. A single-engine sale contributed $21.1 million to that total. The rest came from heightened demand for surplus components, as airlines attempt to extend the lifespan of their existing fleets amid ongoing delivery delays for new aircraft.

Willis Lease Finance reported a $27.6 million gain from selling 14 engines, two airframes, and various components. This was an improvement from the $14.4 million gain in Q2 2024. The company also finalized the sale of its UK-based consultancy, Bridgend Asset Management Limited, to its WMES joint venture, adding another $43 million in one-time gains.

As of June 30, 2025, the company’s total lease-related assets stood at $3.25 billion. This includes equipment under operating lease, notes receivable, maintenance rights, and sales-type lease investments.

Willis Lease Finance’s Q2 results underline the strength of the aviation services sector as it adapts to post-pandemic market realities. With airlines cautious about capital spending and global supply chains still facing backlogs, the demand for leasing and aftermarket services is expected to remain firm.
