Rosen Law Firm says GPGI investors may join securities fraud class action

Rosen Law Firm says investors who bought GPGI Class A common stock during a set class period may be eligible to seek compensation in a securities fraud case.
Rosen Law Firm said on Sept. 4, 2026, that investors who bought Class A common stock of GPGI, Inc., formerly CompoSecure, Inc., between Nov. 3, 2025 and May 6, 2026 may be eligible to join a securities fraud class action.
The notice said a class action lawsuit has already been filed and that investors who want to serve as lead plaintiff must move the court by Sept. 14, 2026. Rosen said the case concerns shares traded under the symbols NYSE: GPGI and CMPO.
According to the notice, purchasers during the class period may be entitled to compensation without out-of-pocket fees or costs through a contingency fee arrangement. It also said a lead plaintiff is a representative party who acts on behalf of other class members in directing the litigation.
The notice alleges defendants overstated the value of Husky and failed to disclose that Husky was not on track to meet revenue and Adjusted EBITDA targets in the proxy statement. It also says the suit alleges those targets lacked a reasonable basis in objective fact.
The filing also alleges the Husky acquisition was driven in part by fees for Resolute Holdings and individual defendants, rather than by a plan to create long-term value for CompoSecure shareholders. It says defendants misrepresented the business, prospects and expected financial results of GPGI and Husky as a combined business.
Rosen said investors suffered damages when the truth entered the market. The notice does not provide a court ruling on the claims and presents the allegations as part of the pending case.
The notice included contact details for investors who want to join the action through Rosen Law Firm, including a web link, phone number and email address.
The next deadline is Sept. 14 for any investor seeking appointment as lead plaintiff. The class action itself is already pending.
