GPGI, CMPO DEADLINE: ROSEN, REGARDED INVESTOR COUNSEL, Encourages GPGI, Inc. f/k/a CompoSecure, Inc. Investors with Losses in Excess of $100K to Secure Counsel Before Important September 14 Deadline in Securities Class Action - GPGI, CMPO

Rosen Law Firm, a global investor rights law firm, reminds purchasers of Class A common stock of GPGI, Inc. f/k/a CompoSecure, Inc. (NYSE: GPGI) (NYSE: CMPO) between November 3, 2025 and May 6, 2026, inclusive (the "Class Period"), of the important September 14, 2026 lead plaintiff deadline.

If you purchased GPGI Class A common stock during the Class Period you may be entitled to compensation without payment of any out of pocket fees or costs through a contingency fee arrangement.

A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than September 14, 2026. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.

According to the lawsuit, throughout the Class Period, defendants made materially false and misleading statements and/or failed to disclose that: (1) defendants had materially overstated the value of Husky; (2) Husky was not on track to achieve the revenue and Adjusted EBITDA targets provided in the 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 and the individual defendants, rather than to create long-term value for CompoSecure shareholders; and (4) as a result, defendants had materially misrepresented the business, prospects, and expected financial results of GPGI and Husky as a combined business. When the true details entered the market, the lawsuit claims that investors suffered damages.
