Robbins LLP is Investigating Allegations that GPCI, Inc. (GPGI) (formerly CompoSecure) Misled Investors Regarding the Value and Benefits of the Husky Acquisition

Robbins LLP informs stockholders that a class action was filed on behalf of all investors who purchased or otherwise acquired GPGI, Inc. (NYSE: GPGI) Class A common stock between November 3, 2025 and May 6, 2026. GPGI, Inc. has historically operated a financial technology and security business. Prior to the Company’s January 2026 rebranding, GPGI Class A common stock traded under the ticker symbol “CMPO.” After the rebranding, GPGI Class A common stock traded under the ticker symbol “GPGI.”

The Allegations

According to the complaint, on November 3, 2025, CompoSecure, announced that it had entered into an agreement to acquire Husky Technologies Limited. Defendants touted the purported value, operational and financial strength, and growth prospects of Husky to secure shareholder support of the Husky acquisition. On January 12, 2026, CompoSecure announced the completion of the Husky acquisition and that the Company would be rebranding as “GPGI, Inc.”

Plaintiff alleges that during the class period, defendants failed to disclose:

(a) that defendants had materially overstated the value of Husky;

(b) that 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; and

(c) that 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.

Plaintiff alleges that on February 26, 2026, short seller Jehoshaphat Research (“JR”) announced a new report that claimed GPGI had overstated the value of Husky in order obtain shareholder approval for the Husky acquisition. Since the publication of the JR Report on February 26, 2026,

GPGI’s share price declined from a close of $23.12 per share to $12.94 per share on May 7, 2026, a decline of 44%.
