• Settlements have been reached in a class action antitrust lawsuit filed on behalf of the End-User Settlement Class of PVC Pipe Products with Atkore Inc., Atkore International, Inc., Atkore Plastic Pipe Corp., Atkore RMCP, Inc., and Allied Tube & Conduit Corporation (collectively, “Atkore”) and Otter Tail Corporation, Northern Pipe Products, Inc., and Vinyltech Corporation (collectively, “Northern Pipe and Vinyltech” and with Atkore, “Settling Defendants”). These Settlements only apply to the Settling Defendants and do not dismiss claims against other Defendants in the case in the United States District Court for the Northern District of Illinois entitled In re: PVC Pipe Antitrust Litigation, Case No. 1:24-cv-07639 (N.D. Ill.).
   
• If approved by the Court, the Settlements will resolve whether and to what extent the Settling Defendants participated in a combination or conspiracy with other co-Defendant PVC Pipe Product producers (“Non-Settling Defendants” or “Non-Settling Converter Defendants”) (together with the Settling Defendants, the “Converter Defendants”) to restrain trade, the purpose and effect of which was to suppress competition and to charge supra-competitive prices for PVC Pipe Products from September 1, 2017, through June 10, 2026, in violation of federal and state laws. If approved, these Settlements will avoid litigation costs and risks to End-User Settlement Class and the Settling Defendants and will release the Settling Defendants from liability to End-User Settlement Class.
   
• The Settlements require Atkore to pay $50,000,000 and Northern Pipe and Vinyltech to pay $30,000,000 to the End-User Settlement Class. In addition to these monetary payments, the Settling Defendants have agreed to provide specified cooperation in the End-User Settlement Class’s continued prosecution of the litigation. There will be no payment of claims to the End-User Settlement Class members at this time. You will be notified later of an opportunity to file a claim.
   
• In addition to seeking approval of the Settlements, Interim Co-Lead Counsel will seek an interim payment of up to $4,000,000 for litigation expenses from the Settlements pro rata to reimburse past expenses and assist in the ongoing prosecution of the case.
   
• The Court has not decided whether the Settling Defendants did anything wrong, and the Settling Defendants do not concede or admit any liability for alleged wrongdoing.
   
• PLEASE NOTE: The End User Class previously sent out a Court approved notice concerning a Settlement with Defendant Oil Price Information Service, LLC ("OPIS"). The deadline to submit an objection to or Exclusion Request from the End User Class Settlement with OPIS was April 9, 2026. The Final Fairness Hearing for the End User Class Settlement with OPIS was held Wednesday, June 3, 2026.
