Rosen Law Firm Initiates Securities Fraud Lawsuit Against GPGI, Inc.

New York, NY – July 15, 2026 – Rosen Law Firm, a global investor rights law firm, announced the filing of a class action lawsuit against GPGI, Inc. (formerly CompoSecure, Inc., NYSE: GPGI, CMPO). The suit is brought on behalf of purchasers of the company's Class A common stock during the period from November 3, 2025, through May 6, 2026, inclusive.

Investors who purchased GPGI Class A common stock during the specified Class Period may be entitled to compensation without payment of any out-of-pocket fees or costs, according to the law firm. The lawsuit claims that the defendants made materially false and misleading statements and/or failed to disclose critical information to investors.

The complaint alleges that defendants overstated the value of an acquisition referred to as "Husky" and misrepresented its financial prospects. Specifically, the suit claims that the revenue and Adjusted EBITDA targets for "Husky" lacked a reasonable basis and that a primary motivation for the acquisition was to generate fees for certain parties, rather than to create shareholder value. Investors allegedly suffered damages when the true details of the business combination became public.

Rosen Law Firm is seeking investors who wish to serve as lead plaintiff in this action and must move the Court no later than September 14, 2026. A lead plaintiff is a representative party that acts on behalf of other class members in directing the litigation. The firm encourages investors to select counsel with a track record of success in leadership roles in securities class actions.
