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.

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.
