Rhea-AI Summary

Koppers Holdings Inc. reported sharply weaker results for the quarter and six months ended June 30, 2026, driven by large impairment and restructuring charges tied mainly to shutting down distillation and chemical manufacturing at its Stickney, Illinois facility and other network optimization actions.

For the quarter, net sales were $520.1 million, up modestly from $504.8 million, but the company recorded a net loss of $147.5 million versus income of $16.4 million a year earlier. Impairment and restructuring expense jumped to $215.8 million in the quarter, leading to an operating loss of $166.0 million. Adjusted EBITDA, which excludes these items and other non‑recurring factors, was $71.0 million, down from $77.1 million.

By segment, Railroad and Utility Products and Services saw lower adjusted EBITDA on weaker pricing and mix, while Performance Chemicals delivered higher sales and adjusted EBITDA, helped by volume growth and lower net raw material costs. Carbon Materials and Chemicals experienced a steep adjusted EBITDA decline due to higher costs despite savings from prior shutdowns. For the first half, operating activities generated $96.3 million of cash, total debt was $905.7 million, and shareholders’ equity declined to $387.0 million after restructuring charges and share repurchases.
