Rosen Law Firm reminds investors who purchased securities of Graphic Packaging Holding Company between February 4, 2025, and February 2, 2026, of the July 6, 2026, deadline to serve as lead plaintiff in a securities class action lawsuit. The lawsuit alleges that throughout the Class Period, defendants made false and misleading statements and failed to disclose significant inventory management issues, reduced demand, increased costs, and the unreliability of full year 2025 financial guidance. Investors who purchased securities during this period may be entitled to compensation without payment of any out-of-pocket fees or costs through a contingency fee arrangement.

Allegations Against Graphic Packaging

According to the lawsuit, defendants downplayed the true scope and severity of operational issues, which materially impacted Graphic Packaging's business and financial results. The complaint claims that the company overstated the strength and sustainability of its business model and its ability to weather macroeconomic headwinds. As a result, the full year 2025 financial guidance issued by the company was allegedly unreliable and unrealistic.

Key Case Details

Investor Options and Next Steps

A class action lawsuit has already been filed. Investors wishing to serve as lead plaintiff must move the Court no later than July 6, 2026. The lead plaintiff acts as a representative party for other class members in directing the litigation. Investors may also choose to remain an absent class member and do nothing at this point. An investor's ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.
