Portnoy Law Firm Announces Class Action on Behalf of GPGI, Inc. Investors
The Portnoy Law Firm has announced a class action lawsuit on behalf of GPGI, Inc. investors who purchased securities between November 3, 2025 and May 6, 2026. The lawsuit follows two major stock price declines triggered by disappointing earnings reports and significant guidance cuts. In March 2026, GPGI's stock fell 16.36% after reporting compressed EBITDA margins at its Husky Technologies segment. In May 2026, the stock plummeted an additional 25.89% following weak Q1 results and substantial downward revisions to full-year guidance.
