Rosen Law Firm reminded purchasers of GPGI, Inc. Class A common stock that September 14, 2026, is the deadline to move for appointment as lead plaintiff in a proposed securities class action. The case covers purchases made from November 3, 2025, through May 6, 2026, inclusive. GPGI was formerly known as CompoSecure, Inc. and trades under GPGI and CMPO. The lawsuit alleges that defendants overstated Husky’s value, set revenue and Adjusted EBITDA targets without a reasonable basis, and misrepresented the acquisition’s purpose and the combined company’s prospects. It claims the transaction was motivated in part by fees for Resolute Holdings and individual defendants rather than long-term shareholder value. The class has not been certified. Investors may seek lead-plaintiff status, retain counsel, or remain absent class members without taking action, and participation in any future recovery does not depend on serving as lead plaintiff.
