PHILADELPHIA, June 8, 2026 /PRNewswire/ — The following statement is being issued by Kroll Settlement Administration regarding In re PVC Pipe Antitrust Litigation.

Two new settlements have been reached in a class action lawsuit called In re PVC Pipe Antitrust Litigation, No. 1:24-cv-07639 (the “Action”), which was filed on behalf of Non-Converter Seller Purchasers (“NCSPs”) of PVC Pipe and PVC Fittings (“PVC Pipe Systems”) and is pending in the United States District Court for the Northern District of Illinois (the “Court”). First, NCSPs have reached a settlement with Defendants Atkore Inc., Atkore International, Inc., Atkore Plastic Pipe Corp., Atkore RMCP, Inc., Allied Tube & Conduit Corporation, and affiliated brands Heritage, Queen City Plastics, Rocky Mountain Colby Pipe, and Cor-Tek (hereinafter, “Atkore Defendants”). Second, NCSPs have reached a settlement with Defendants Otter Tail Corporation, Northern Pipe Products, Inc., and Vinyltech Corporation (“Northern Pipe and Vinyltech Defendants,” and collectively with Atkore Defendants, “Settling Defendants”). These Settlements apply only to Settling Defendants and do not dismiss claims against other Defendants in the Action. NCSPs allege that Settling Defendants and their co-conspirators conspired and combined to fix, raise, maintain, and stabilize the price of PVC Pipe and PVC Fittings (“PVC Pipe Systems”) from January 1, 2020, through at least May 13, 2026, with the intent and expected result of increasing prices of PVC Pipe Systems sold in the United States and its territories, in violation of federal antitrust laws and various state antitrust and consumer protection laws.
