Financial Performance and Impact

The catalyst for this lawsuit arose when GPGI disclosed significant details regarding its financial performance for the fourth quarter of FY25. The firm reported $520.8 million in net sales for Q4, marking a modest year-over-year increase of 6.1%. However, the concerning news of a decline in Pro Forma Adjusted EBITDA of 5.4% year-over-year to $136.1 million raised many eyebrows among investors. This financial setback was further compounded by a drop in EBITDA margins for this segment of the business, which led to a swift reaction in GPGI's stock price.

The grim outlook was confirmed on May 7, 2026, when GPGI reported first-quarter results, indicating a staggering year-over-year decrease of 40.2% in Pro Forma Adjusted EBITDA, leading to a revised forecast for both sales and EBITDA for 2026. Following this news, GPGI's stock price endured a substantial decline of 25.89% in a single trading session, further influencing the decision to pursue legal action.
