CLASS ACTION LAWSUIT - COMPLAINT ALLEGATION SUMMARY: 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.
