AEVEX Corp. and certain executives face a securities class action alleging they concealed a pre-arranged plan to override a 180-day IPO lock-up affecting Madison, the company’s former 100% common-stock owner. ClaimsFiler said investors who bought or otherwise acquired AEVEX publicly traded Class A common stock from April 17 through June 4, 2026, inclusive, and/or pursuant or traceable to the IPO registration statement and prospectus, have until Oct. 20, 2026, to seek lead-plaintiff appointment. The lawsuit alleges AEVEX represented that Madison could not sell Class A shares or convert or exchange Class B shares or LLC Units for public sale until at least Oct. 13, 2026, while concealing an arrangement that allegedly cleared the way for a secondary public offering. The complaint says Madison would receive more than $200 million and the underwriter defendants would share more than $8 million in fees.
