A class action filed by Robbins LLP alleges that AEVEX Corp. concealed a pre-arranged plan involving Madison, its controlling shareholder, to override a 180-day lock-up after the company’s April 17, 2026, initial public offering. Madison owned all of AEVEX before the IPO and retained 77.5% afterward. The complaint says AEVEX disclosed the planned secondary public offering only after filing an SEC registration statement on June 1, followed by the sale of eight million Class A shares at $27 each on June 3. Madison allegedly received more than $200 million from the transaction, while AEVEX received no proceeds and the underwriters collected more than $8 million in additional fees. AEVEX shares fell about 16% on June 2, eliminating more than $700 million in market value, and declined another 7% on June 5, erasing about $200 million more. The proposed class covers investors who bought AEVEX Class A stock from April 17 through June 4, 2026, or in the IPO. Investors seeking lead-plaintiff status must act by October 20, 2026.
