Robbins Geller Rudman & Dowd LLP said it is investigating potential violations of U.S. federal securities laws involving GPGI, Inc. after the company’s May 7, 2026 first-quarter results showed a sharp slowdown in its Husky segment. GPGI reported Pro Forma Adjusted Net Sales of $290.8 million for the segment, down 5.2% year over year, while Pro Forma Adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) fell 40.2% to $38 million. The law firm said GPGI’s stock dropped nearly 26% on that news. GPGI, together with its subsidiaries, provides sustainable injection molding solutions worldwide. Robbins Geller invited investors who suffered losses or have information relevant to the matter to contact attorneys Ken Dolitsky or Michael Albert.
