Air Lease Corporation (NYSE: AL) saw its stock price plummet 5.26% in after-hours trading on Monday, despite reporting strong second-quarter results that surpassed analyst expectations. The aircraft leasing company announced a substantial increase in both revenue and net income, yet investors seemed to focus on other factors driving the stock down.

For Q2 2025, Air Lease reported revenues of $731.7 million, a 9.7% increase from the same period last year and beating the analyst consensus estimate of $720.96 million. The company's net income soared to $374 million, or $3.33 per diluted share, compared to $90.4 million in the previous year, marking a remarkable 313.8% increase. However, the adjusted earnings per share of $1.40, while up 13.82% year-over-year, missed the analyst estimate of $1.69 by 17.21%.

The company attributed its strong performance to fleet expansion, higher end-of-lease revenue, and substantial recoveries related to the Russian fleet write-off. Air Lease also recorded a $344 million insurance claim settlement related to its former Russian fleet. Despite the positive financial results and the company's optimistic outlook on robust aircraft demand supporting margin expansion, the market's after-hours reaction suggests investors may be concerned about factors not immediately apparent in the earnings report, such as the adjusted EPS miss or potential headwinds in the aviation leasing industry.
