Koppers Holdings is under investigation by Levi & Korsinsky after reporting a 38% year-over-year drop in net income and cutting its 2026 earnings guidance, causing shares to decline.
On November 6, 2026 Koppers reported Q3 adjusted EBITDA down 18% to $58 million, net income down roughly 38% year over year, and cut full-year 2026 adjusted EPS guidance from $3.80–$4.20 to $3.10–$3.25, already sending shares lower. A pending Levi & Korsinsky securities investigation into possible misleading statements adds legal overhang and further selling pressure in the coming weeks.
Third-quarter 2026 adjusted EBITDA fell 18% to $58 million and net income dropped about 38% year over year, and the company cut its full-year 2026 adjusted EPS guidance from $3.80–$4.20 to $3.10–$3.25, which sent the shares lower.
The firm is investigating whether Koppers made materially false or misleading statements about its business and fiscal 2026 outlook. Investors who bought KOP and suffered losses may be eligible to participate, whether or not they still hold the shares, at no upfront cost.
