AEVEX Investors Face October Deadline in Securities Class Action

The lawsuit, Rosenberg v. AEVEX Corp., claims that the company, its private equity owner Madison Dearborn Partners, and top executives violated securities laws by concealing a pre-arranged plan to bypass a 180-day lock-up agreement. While the IPO documents indicated that Madison Dearborn would not sell its Class A shares until at least October 13, 2026, the complaint alleges that defendants secretly coordinated with underwriters including Goldman Sachs, BofA Securities, and Jefferies to launch a secondary public offering shortly after the IPO.

The market reacted sharply to these developments. Following the June 1, 2026 announcement of a secondary offering, AEVEX stock dropped approximately 16%. A subsequent 7% decline occurred on June 5 after the company filed a final prospectus revealing the waiver of the lock-up restrictions. Robbins Geller Rudman & Dowd LLP is representing the plaintiffs, seeking to hold the company accountable for the losses incurred during the April 17 to June 4 class period.
