Levi & Korsinsky Notifies Investors of Pending Investigation Into Securities Claims Involving Koppers Holdings Inc. (KOP)

KOP shares fell after the Company's third-quarter adjusted EPS of $0.77 substantially missed analyst estimates of approximately $1.34 to $1.37, and the Company lowered its fiscal 2026 financial outlook. Levi & Korsinsky is investigating on behalf of KOP investors who suffered losses

NEW YORK, Nov. 11, 2026 (GLOBE NEWSWIRE) -- Koppers Holdings Inc. (NYSE: KOP) shares fell after the Company reported third-quarter adjusted EPS of $0.77, approximately 43% below the Street estimate of $1.37, and lowered its full-year 2026 financial guidance. If you bought Koppers shares and are now facing losses, you are encouraged to submit your KOP loss information now. You may also contact Joseph E. Levi, Esq. via email at jlevi@levikorsinsky.com or by telephone at (212) 363-7500.

Revenue also came in below expectations. Koppers reported third-quarter revenue of $499.1 million, compared with analyst consensus estimates of approximately $512.35 million. Net income fell approximately 38%, while adjusted EBITDA declined 18% to $58 million.

KOP also reduced its fiscal 2026 adjusted EBITDA guidance to $220 million–$225 million and its adjusted EPS guidance to $3.10–$3.25. The reduced outlook reflected higher-than-anticipated raw material and logistics costs, partially driven by elevated energy prices, which management expected to continue pressuring margins through the remainder of 2026. SG&A expenses also increased $3.4 million year over year, primarily due to higher compensation-related and technology costs. Levi & Korsinsky is investigating potential securities law violations on behalf of Koppers investors who lost money.

Koppers shareholders who lost money can request a no-cost review of their KOP losses or call (212) 363-7500.
