Portnoy Law said it has opened an investigation into possible securities fraud at Graphic Packaging and may file a class action on behalf of investors. The firm said the probe is examining whether the board mismanaged the company or breached fiduciary duties following executive leadership changes. Portnoy Law cited a December 2025 shareholder letter from an investor with a 4.2% stake that followed the announcement that Michael Doss would be replaced as CEO by Robbert E. Rietbroek. The firm also pointed to the departure of the company’s executive vice president and general counsel weeks after the CEO transition was announced.
