AEVEX Corp. investors who bought or acquired Class A common stock in connection with the company’s April 2026 initial public offering or between April 17 and June 4, 2026, have until Oct. 20, 2026, to seek appointment as lead plaintiff in a securities-fraud class action. Wolf Haldenstein Adler Freeman & Herz LLP announced the action on Aug. 28, alleging that AEVEX, controlling private equity owner Madison Dearborn Partners, LLC, certain executives and directors, and IPO underwriters concealed a pre-arranged plan to waive a 180-day lock-up and conduct a secondary public offering shortly after the IPO. AEVEX designs and manufactures unmanned aerial and surface vehicles and provides artificial-intelligence-enabled intelligence, surveillance and reconnaissance services. The complaint says the company sold 18.4 million shares in its IPO and later disclosed plans to sell eight million additional Class A shares. On June 1, 2026, AEVEX filed a registration statement for the secondary offering; the stock fell approximately 16% on June 2 and another 7% on June 5. The offering generated $207.9 million, which the complaint says went to Madison Dearborn, while existing case materials estimate roughly $900 million in lost shareholder market value across the two sessions. Investors may seek lead-plaintiff status through counsel of their choice, take no action and remain absent class members, or participate through other firms that have publicized the case.
