Grabar Law Office is investigating potential claims on behalf of current shareholders of AEVEX Corp. (NYSE: AVEX) concerning alleged breaches of fiduciary duty and other corporate governance issues involving certain officers, directors, and controlling shareholders of the Company.

The investigation follows the filing of a federal securities class action, Rosenberg v. AEVEX Corp., et al., No. 3:26-cv-04779 (S.D. Cal.), which asserts claims under the Securities Act of 1933 and Securities Exchange Act of 1934 against AEVEX, certain Company executives and directors, Madison Dearborn Partners, LLC (“Madison”), and the lead underwriters of AEVEX’s April 2026 initial public offering (“IPO”).

According to the underlying securities fraud class action complaint, AEVEX’s IPO offering documents represented that Madison—AEVEX’s controlling private-equity owner—would be subject to a 180-day lock-up period restricting sales of its AEVEX holdings until October 13, 2026. The lawsuit alleges, however, that defendants concealed a pre-arranged plan to waive those restrictions and conduct a secondary public offering shortly after the IPO.

That underlying complaint alleges that, only weeks after the IPO, AEVEX conducted an eight-million-share secondary offering. Approximately 2.27 million shares were sold directly from Madison’s holdings, while AEVEX issued approximately 5.73 million additional shares and allegedly used the proceeds to purchase other AEVEX interests from Madison. According to the complaint, the entire $207.9 million in net proceeds from the secondary offering ultimately went to Madison, while AEVEX received no net proceeds from the transaction.

The underlying complaint further alleges that Madison retained substantial control over AEVEX. Following the IPO, Madison reportedly owned approximately 77.5% of AEVEX’s common stock, and the IPO documents provided Madison with significant rights to designate members of AEVEX’s Board of Directors.

Following disclosure of the secondary offering, AEVEX’s share price allegedly declined approximately 16% on June 2, 2026, resulting in more than $700 million in lost market capitalization, and declined an additional 7% on June 5, 2026following further disclosures concerning the transaction.
