Investors File Securities Class Action Against Graphic Packaging in SDNY

Overview

• A class action complaint was filed in the U.S. District Court for the Southern District of New York (docket 26-cv-03790) on behalf of investors who bought Graphic Packaging securities between February 4, 2025 and February 2, 2026.
• The complaint alleges the company and certain former officers made false or misleading statements by concealing significant inventory-management problems, falling volumes, and rising input costs that undercut prior guidance.
• The suit cites a sequence of company disclosures that investors say revealed the truth: a May 1, 2025 guidance cut and earnings miss, a December 8, 2025 acceleration of inventory reductions and CEO Michael Doss’s exit, and a February 3, 2026 report that missed estimates while forecasting a roughly $130 million inventory-related hit and an about $100 million accrual.
• Multiple plaintiff law firms are soliciting investors to join the case and to seek appointment as lead plaintiff before the July 6, 2026 deadline, with the court set to choose the investor with the largest adequate financial interest to steer the litigation.
• The complaints seek damages under federal securities laws, including Sections 10(b) and 20(a) and Rule 10b-5, but no court rulings on liability or relief have been issued and any recovery will depend on the lead-plaintiff appointment and later litigation outcomes.
