Guidance, Outlook, Risks, and Unusual Items
Management Commentary and Outlook
Management expects continued growth in the spare engine leasing industry driven by fleet expansion and increasing lease penetration rates. The company maintains a robust risk management program, utilizing a mix of fixed and floating rate debt and interest rate swaps to manage interest rate exposure. As of December 31, 2025, $732.7 million of debt was variable rate. The company believes its liquidity position, supported by $350.0 million available under its revolving credit facility and $417.3 million under its warehouse facility, is sufficient to maintain operations through 2026.
Risks and Contingencies
- Geopolitical Instability: The filing highlights risks associated with the United States-Israel-Iran conflict and U.S. intervention in Venezuela, noting potential airspace closures and economic disruption.
- Customer Concentration: One customer accounted for approximately 13% of total lease rent revenue in 2025. One customer accounted for 15% of total receivables.
- Regulatory Changes: Stricter environmental regulations (e.g., EU ETS, CORSIA) and noise standards (Stage IV) could impact the value and leaseability of older engines.
- Interest Rate Risk: A 1% increase in interest rates would increase annual interest expense on variable rate debt by approximately $4.0 million.
Unusual Items
- Gain on Sale of Business: $43.0 million gain from the sale of BAML to WMES.
- Stock Repurchase: The company repurchased 30,000 shares from the Executive Chairman at a 2% discount to the VWAP, outside of the public repurchase plan.
- Investment Fund Partnerships: Entered into new partnerships with Liberty Mutual Investments (up to $600 million) and Blackstone Credit & Insurance (over $1 billion) in December 2025, though no investment activity occurred in 2025.
