Willis Lease Finance Corporation, a Delaware-based company, filed its annual report for the fiscal year ended December 31, 2024. The company reported total revenues of $243.1 million, a 12% increase from the previous year, driven by growth in its aircraft leasing business. Net income was $34.4 million, a 15% increase from the previous year. The company’s assets increased by 10% to $1.4 billion, primarily due to the acquisition of new aircraft and the growth of its existing fleet. The company’s cash and cash equivalents decreased by 15% to $143.1 million, primarily due to the repayment of debt and the purchase of new aircraft. The company’s debt-to-equity ratio remained stable at 0.6, indicating a strong balance sheet. The company’s stock price increased by 20% to $69.30 per share, resulting in an aggregate market value of voting stock held by non-affiliates of approximately $240.2 million.
Overview of Willis Aero’s Financial Performance
Willis Aero is a wholly-owned subsidiary focused on the sale of aircraft engine parts and materials, as well as an engine management and consulting business through its Willis Asset Management subsidiary. The company also has two joint ventures - WMES, a Dublin-based engine leasing company, and CASC Willis, a China-based engine leasing joint venture.
In 2024, Willis Aero reported total revenue of $569.2 million, a 36.0% increase from 2023. This strong performance was driven by growth across multiple revenue streams, including a 11.8% increase in lease rent revenue, a 60.0% jump in maintenance reserve revenue, and a 325.9% surge in gains on the sale of leased equipment.
The company’s profitability also improved, with net income increasing 88.6% to $44.0 million. This was aided by the growth in high-margin revenue sources like maintenance reserves and equipment sales, as well as disciplined cost management. However, general and administrative expenses rose 26.8% due to higher personnel costs, including increased share-based compensation.
Revenue and Profit Trends
Lease rent revenue, which makes up the largest portion of Willis Aero’s top line, grew 11.8% to $238.2 million in 2024. This was driven by an increase in the average size of the company’s lease portfolio, though utilization rates dipped slightly to 83% from 84% the prior year. Two customers accounted for around 11% of total lease rent revenue each.
Maintenance reserve revenue, the second largest revenue stream, surged 60.0% to $213.9 million. This included a 60.0% increase in short-term maintenance revenue as well as a 156.5% jump in long-term maintenance revenue tied to end-of-lease compensation. The increase reflects higher engine usage fees and the timing of maintenance reserve recognition.
Spare parts and equipment sales also saw strong growth, rising 33.1% to $27.1 million, as operators looked to extend the life of their current engine portfolios. Equipment sales contributed $1.0 million in revenue. Interest revenue grew 34.0% to $11.7 million due to an increase in notes receivable.
The company recorded a substantial 325.9% increase in gains on the sale of leased equipment, reaching $45.1 million. This reflects the company’s active management of its lease portfolio, with 35 engines, 8 airframes, and other parts and equipment sold during the year.
On the expense side, depreciation and amortization rose 1.7% to $92.5 million, in line with the growth in the lease portfolio. Cost of spare parts and equipment sales increased 50.3% to $22.9 million. Write-downs of equipment totaled $11.2 million, up from $4.4 million the prior year, as the company adjusted the carrying value of certain assets.
General and administrative expenses saw a 26.8% jump to $146.8 million, primarily due to a $35.5 million increase in personnel costs, including $14.4 million in higher share-based compensation. Technical expenses declined 20.7% to $22.3 million on lower engine repair activity.
Net finance costs rose 33.0% to $104.8 million, reflecting higher debt levels and borrowing costs, partially offset by a decrease in interest expense on the company’s credit facility. Income tax expense increased 88.6% to $44.0 million, though the effective tax rate declined from 34.8% to 28.8% due to a decrease in state taxes.
Overall, Willis Aero’s strong revenue growth and disciplined cost management led to a significant 88.6% increase in net income to $44.0 million.
Strengths and Weaknesses
One of Willis Aero’s key strengths is its diversified revenue streams. While lease rent revenue remains the largest contributor, the company has built a substantial maintenance reserve business as well as a profitable parts and equipment sales operation. This diversification helps mitigate risk and provides multiple avenues for growth.
The company’s active management of its lease portfolio is also a strength, as evidenced by the significant gains on equipment sales. This demonstrates the company’s ability to optimize the value of its assets over their lifecycle.
Additionally, Willis Aero’s joint venture investments in WMES and CASC Willis provide exposure to the growing global engine leasing market, particularly in Europe and China. These partnerships allow the company to leverage additional expertise and capital to expand its reach.
However, the company’s reliance on debt financing is a potential weakness. While the company has been able to access capital markets to fund growth, a rise in interest rates could squeeze margins if lease rates cannot be adjusted quickly enough. The company’s high general and administrative expenses, driven by personnel costs, is another area that bears watching.
Furthermore, the company’s exposure to the aviation industry, which can be cyclical, introduces some risk. A downturn in air travel or airline profitability could negatively impact demand for the company’s leasing and parts services.
Outlook and Future Prospects
Looking ahead, Willis Aero appears well-positioned for continued growth. The company’s diversified revenue streams, active asset management, and global partnerships provide a solid foundation. The strong demand for leased engines and aircraft parts should continue to drive performance in the core business.
However, the company will need to carefully manage its cost structure, particularly personnel expenses, to maintain profitability. Navigating potential interest rate increases and industry cycles will also be crucial.
Overall, Willis Aero’s 2024 financial results demonstrate the company’s ability to capitalize on opportunities in the aviation services market. With its diverse revenue mix, global reach, and disciplined approach to operations, the company appears poised to build on this momentum in the years ahead.
