Financial Overview

Third Quarter 2026 vs. Third Quarter 2025

Our rental of flight equipment revenues for the three months ended September 30, 2026, decreased by approximately 18.2%, to $556.7 million, as compared to $680.9 million for the three months ended September 30, 2025. The decrease is primarily due to a lower weighted average net book value of our flight equipment subject to operating leases resulting from the sale of our orderbook and continued sales activity. The net book value of our flight equipment subject to operating leases decreased to $23.7 billion as of September 30, 2026 from a net book value of $29.5 billion as of September 30, 2025.

Our gain on aircraft sales and trading and other income decreased to $36.0 million compared to $44.5 million for the three months ended September 30, 2025. The decrease was primarily driven by lower gains on aircraft sales as a result of acquisition accounting adjustments, partially offset by higher management fee revenue attributable to disposition fees earned on sales of managed aircraft. As a result of the application of the acquisition method of accounting, the carrying values of our flight equipment subject to operating leases and our flight equipment held for sale as of the date of the merger were adjusted to fair value. For the three months ended September 30, 2026, we sold 15 aircraft to third parties resulting in $0.6 million in gains compared to $35.0 million in gains from the sale of five aircraft for the three months ended September 30, 2025. Sales proceeds for the 15 aircraft sold during the three months ended September 30, 2026 were $761.9 million.

Excluding the $27.3 million and $60.5 million insurance recoveries related to our Russian fleet in the three months ended September 30, 2026, and 2025, respectively, total operating expenses decreased 17.9% to $493.1 million for the three months ended September 30, 2026, compared to $600.9 million in the prior-year period. The decrease was primarily due to lower depreciation expense because of a decrease in the weighted average net book value of our flight equipment subject to operating leases, resulting from the sale of our orderbook and continued sales activity and revised aircraft depreciation estimates, partially offset by an increase in servicing fees and higher interest expense due to the amortization of fair value adjustments resulting from purchase accounting, and an increase in our composite cost of funds.

During the three months ended September 30, 2026, we reported a net income attributable to common stockholders of $93.4 million, compared to net income attributable to common sto
