Koppers Holdings (KOP) moved back to profitability in Q1 2026, reporting net sales of $455.3 million, essentially flat versus a year ago, and net income of $7.1 million after a prior-year loss of $13.9 million. Diluted EPS was $0.35 compared with a loss of $0.68.
Performance Chemicals led growth with sales up 17.5% to $142.1 million and stronger margins, while Railroad and Utility Products and Services and Carbon Materials and Chemicals both saw lower sales and profitability. Consolidated adjusted EBITDA fell 11.2% to $49.3 million, pressured mainly by weaker pricing and earnings in Carbon Materials and Chemicals.
Operating cash flow improved sharply to $46.3 million from an outflow of $22.7 million, helped by better working capital. Net debt remained high at $928.8 million, with a total net leverage ratio of 3.4 under the company’s credit facility.
After quarter-end, Koppers announced a conditional plan to discontinue distillation and chemical manufacturing at its Stickney, Illinois facility by the end of 2026. The company expects total pre-tax charges of $227 million to $262 million through 2029, mostly non-cash accelerated depreciation and asset write-downs, plus demolition and clean-up costs. Management frames this as part of a broader multi-year transformation to shift toward higher-margin, less capital-intensive operations.
