A securities fraud class action has been filed against AEVEX Corp. for investors who purchased or acquired Class A common stock from April 17, 2026, through June 4, 2026, or pursuant to the company’s April 17 initial public offering. The lawsuit, Rosenberg v. AEVEX Corp., No. 26-cv-04779, is pending in the U.S. District Court for the Southern District of California. AEVEX is a military technology contractor that designs unmanned aerial and surface vehicles and provides AI-enabled intelligence, surveillance and reconnaissance services. The complaint alleges that AEVEX and other defendants failed to disclose a pre-arranged plan involving Madison Dearborn Partners, which owned all of AEVEX’s common stock by the IPO, to waive a 180-day lock-up and conduct a secondary public offering shortly afterward. A registration statement filed June 1 announced an offering of eight million Class A shares, and the sale followed on or about June 3. More than two million shares came from Madison’s holdings, while nearly six million newly issued shares were used to purchase an equivalent number of Madison’s other AEVEX holdings. The complaint says the $207.9 million in proceeds went to Madison and AEVEX received no proceeds. AEVEX shares fell approximately 16% on June 2 and another 7% on June 5. Investors have until October 20, 2026, to seek lead-plaintiff status, although investors who do not seek that role may remain absent class members and still participate in any recovery.
