The lawsuit, filed by the Rosen Law Firm, contends that Graphic Packaging downplayed severe inventory management issues and declining demand during the class period. According to the complaint, these omissions rendered the company's 2025 financial guidance unreliable, causing significant losses for shareholders when the true extent of the business struggles surfaced.

While the court has not yet certified a class, investors who purchased shares during the specified timeframe are eligible to participate. Those interested in serving as lead plaintiff must file their motions by the July deadline, though individual investors may also choose to remain absent class members or retain their own counsel. The litigation highlights claims that the company’s public statements regarding its business model and ability to navigate macroeconomic pressures were materially false.
