Koppers Holdings reported Q1 2026 net sales of $455.3 million, showing stable overall revenue but significant volatility in its Carbon Materials and Chemicals segment. While the company returned to a net profit of $7.1 million, adjusted EBITDA fell to $49.3 million due to higher input costs and pricing pressures. To improve long term sustainability and profitability, Koppers announced the closure of its Stickney, Illinois plant by the end of 2026. The company continues to navigate raw material price spikes and competitive pressures within the industrial carbon compounds market.
