Koppers Holdings Reports Q3 2026 Results with Lowered Earnings Guidance Amid Rising Input Costs
Koppers Holdings (KOP) reported third-quarter 2026 net sales of $499.1 million, a 2.8% increase driven by volume growth in wood preservatives and utility poles. However, the company faced significant margin compression, with Adjusted EBITDA falling 18.2% year-over-year to $58.0 million due to rising costs for coal tar, copper, diesel, and logistics. Reflecting these persistent inflationary pressures, Koppers lowered its full-year guidance for both Adjusted EBITDA ($220M–$225M) and Adjusted EPS ($3.10–$3.25). Despite the earnings headwinds, the company achieved record year-to-date operating and free cash flow, supported by improved working capital management and lower capital expenditure requirements.
