Graphic Packaging Sued in New York Securities Class Action Over Inventory and Guidance Claims

Overview

• Pomerantz LLP, which filed the suit Thursday, opened SDNY case 26-cv-03790 on behalf of buyers of GPK shares from February 4, 2025 to February 2, 2026.
• The complaint, which has not been proven in court, alleges the company hid major inventory problems, weaker demand and higher costs, and overstated the strength of its business and 2025 outlook.
• Multiple firms, including Pomerantz, Robbins LLP and Bronstein, Gewirtz & Grossman, are inviting shareholders to join the case or ask to lead it by July 6, 2026.
• Graphic Packaging missed estimates and cut its 2025 guidance on May 1, 2025, then in December accelerated inventory reductions and lowered its outlook again as pressures deepened.
• The company on February 3, 2026 reported a fourth-quarter earnings miss, warned 2026 profit would drop due to a $130 million hit from inventory actions and an approximately $100 million accrual, and its shares fell about 16% as the new CEO began a review.
