GPGI Investor Alert: Kessler Topaz Meltzer & Check, LLP Encourages GPGI Investors with Losses to Contact the Firm

Kessler Topaz Meltzer & Check, LLP informs investors that a securities fraud class action lawsuit has been filed against GPGI, Inc. (GPGI) (NYSE: GPGI) on behalf of those who purchased or acquired GPGI Class A common stock between November 3, 2025 and May 6, 2026, inclusive. The lawsuit is filed in the United States District Court for the Southern District of New York. Investors have until September 14, 2026, to file for lead plaintiff status. The complaint alleges that, throughout the Class Period, Defendants made materially false and/or misleading statements, and/or failed to disclose material adverse facts about the company's business, operations, and prospects. Specifically, Defendants misrepresented and/or failed to disclose that: (1) GPGI had materially overstated the value of Husky Technologies Limited ("Husky"); (2) Husky was not on track to achieve the revenue and Adjusted EBITDA targets provided in the company's proxy statement and such targets lacked a reasonable basis in objective fact; (3) a primary motivation of the Husky acquisition was to generate millions of dollars in fees for Resolute Holdings ("Resolute") and Defendants, rather than to create long-term value for CompoSecure, Inc. ("CompoSecure") shareholders; and (4) as a result, Defendants' statements about the company's business, operations, and prospects were materially false and misleading and/or lacked a reasonable basis at all relevant times. On March 12, 2026, GPGI released its fourth quarter and fiscal year 2025 financial results, disclosing that Husky saw its EBITDA decline 5.4% year-over-year in the quarter and 3% year-over-year for the full year. On this news, the price of GPGI Class A common stock declined $3.23 per share, or approximately 16.4%, over multiple trading sessions, from a close of $19.74 per share on March 11, 2026, to close at $16.51 per share on March 13, 2026.
