AEVEX Investors Seek Lead Plaintiff in Securities Class Action Lawsuit

Executive Signal Summary

Robbins Geller Rudman & Dowd LLP and the Law Offices of Howard G. Smith have announced a lead plaintiff deadline of October 20, 2026, for investors who suffered losses in AEVEX Corp. (NYSE: AVEX) to lead a securities fraud class action lawsuit. The lawsuit, Rosenberg v. AEVEX Corp., alleges that between April 14 and June 4, 2026, defendants made false and misleading statements about a 180-day lock-up agreement following the April 2026 IPO. It claims a pre-arranged plan allowed an early secondary public offering (SPO) of eight million shares, with net proceeds going entirely to Madison Dearborn Partners, leaving AEVEX with zero. This caused a significant stock drop. Investors who purchased AEVEX Class A common stock during the class period have until October 20, 2026, to seek appointment as lead plaintiff.
