Koppers Announces Conditional Plan to Discontinue Production Activities at Facility in Stickney, IllinoisContinues Enterprise-wide Strategy to Focus on Improving Margins and Cash Flow PITTSBURGH, May 8, 2026 /PRNewswire/ -- Koppers Holdings Inc. (NYSE: KOP), an integrated global provider of treated wood products, wood treatment chemicals and carbon compounds, today announced that it has made a conditional decision to discontinue distillation and chemical manufacturing operations at its facility located in Stickney, Illinois, subject to the satisfaction of any bargaining obligations that might exist with the union that represents certain employees at that facility. The conditional decision, which is pending negotiations and consultation with the union and would impact approximately 85 employees, was driven by challenging market conditions over the past decade, including unit operating costs outpacing our ability to capture higher pricing, reduced raw material supply from North American steel manufacturers, and increased capital requirements.
