About Koppers Holdings Inc.
About Koppers Holdings Inc.
Koppers Holdings operates three segments -- Railroad and Utility Products and Services (RUPS), Performance Chemicals (PC), and Carbon Materials and Chemicals (CMC) -- serving railroad, utility, residential lumber, aluminum, steel and construction end-markets from 18 wood treating plants, three coal tar distillation facilities and manufacturing sites across North America, South America, Australasia and Europe. The company's top ten customers accounted for approximately 36% of 2025 net sales, though no single customer exceeded 6%.
Koppers' RUPS and CMC operations are vertically integrated: CMC's coal tar distillation produces creosote that supplies 100% of RUPS's North American creosote requirements for treating crossties and utility poles, while PC supplies chromated copper arsenate and DCOI used in pole and piling treatment. RUPS sells pressure-treated crossties and utility poles primarily under long-term contracts -- about 75% of North American railroad sales are contracted -- competing chiefly against Stella-Jones in crossties and smaller regional rivals in utility poles. PC supplies copper-based wood preservatives to ten of the eleven largest U.S. lumber treating companies and four of the five largest in Canada, purchasing roughly 30 million pounds of scrap copper annually and hedging copper price exposure with swap contracts. CMC's largest competitor, Rain Carbon Inc., competes for creosote and carbon pitch sales, the latter a critical input for aluminum smelting.
Show full overview
Beyond its top-ten customer concentration, Koppers' 10-K flags a structural supply dependency: CMC's creosote output -- sourced partly from a Danish subsidiary -- supplies all of RUPS's North American creosote needs, so a shortage or quality reduction in domestic coal tar could force costlier imports Koppers may not fully pass through to customers. The company also carries $928.3 million in total debt against an $800 million revolving credit facility, and disclosed in May 2026 a conditional plan to wind down chemical manufacturing at its Stickney, Illinois facility by year-end, affecting approximately 85 employees, reflecting a decade of adverse market conditions in that product line.
