Koppers Holdings Inc. (NYSE: KOP), an integrated global provider of treated wood products, wood treatment chemicals, and carbon compounds, announced that Koppers Inc., a wholly-owned subsidiary of Koppers Holdings, has closed on its acquisition of substantially all of the assets of Gross & Janes Co.

Gross & Janes, headquartered in Kirkwood, Missouri, is the largest independent supplier of untreated railroad crossties in North America, with operations in Arkansas, Missouri, and Texas. The company reported approximately $50 million in annual sales in 2021.

Commenting on the transaction, Leroy Ball, President and CEO, said, "I'm glad to get to the point where we have officially added the Gross & Janes team and their network of operations and suppliers to Koppers. The addition further strengthens our vertically integrated business model that brings value to our customer base by de-risking their supply chains for critical products. Furthermore, the synergies realized through this acquisition will be immediately accretive to earnings while also displacing the need for capital spending to replace equipment at certain Koppers legacy operating sites."
