The litigation centers on the company’s performance throughout early 2026, particularly regarding its Husky Technologies segment. On March 12, 2026, GPGI reported a significant compression in adjusted EBITDA margins, which led to a 16.36% drop in share price over two trading sessions. The situation intensified on May 7, 2026, when the firm reported first-quarter results showing a 40.2% year-over-year decline in Husky’s adjusted EBITDA.

Following the May disclosures, GPGI slashed its fiscal 2026 guidance, lowering its net sales forecast to a range of $1.95 billion to $2.10 billion. The subsequent market reaction saw shares plummet another 25.89%, closing at $12.94.
