Koppers Holdings Inc.: what insiders have been doing
Koppers Holdings Inc., classified in the Chemicals & Materials sector, is a listed company based in Pittsburgh, United States, founded in 1912. Its insiders report their share dealings to SEC (Form 4). Between 18 October 2025 and 18 October 2026, 13 insiders published 36 filings.
The flow runs one way only: 10 sales worth €4.0M, from 3 insiders, and no purchase. The totals exclude 2 filings filed without an amount. At €3.5M, the sale published on 11 August 2026 by Sullivan James A. is the largest of the period (0.45% of market cap).
With 36 filings in twelve months, the company is more active than the median of 19 filings across the 5,814 companies we follow on the same exchange. Since 2016, the database holds 2 purchases and 29 sales by insiders of the company. For the fiscal year to 31 December 2025, the annual 10-K puts revenue at 1.88 bn USD and net income at 56.0 m USD, and the dividend at 0.32 USD per share.
Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. The legal deadline for a Form 4 is two business days after the transaction. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.
Elsewhere in the same sector, our signals recently picked up insider purchases at Culp Inc. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.

About Koppers Holdings Inc.
Koppers Holdings Inc. (ticker KOP) is a U.S.-listed industrial company traded on the NYSE/NASDAQ universe; in practice, its shares are listed on the NYSE. For French-speaking investors, Koppers is best understood as a specialty materials and intermediate chemicals business with meaningful exposure to infrastructure, rail, wood treatment, and selected industrial end markets. The company’s roots go back to the early 1900s, when German engineer Heinrich Koppers developed coke-oven technology designed to recover byproducts for reuse rather than release them into the atmosphere. Its headquarters are in Pittsburgh, Pennsylvania, United States. ([koppers.com](https://www.koppers.com/company?utm_source=openai))
Koppers’ business model is built around several complementary segments. On one side, Railroad and Utility Products and Services supplies treated railroad ties, utility-related infrastructure products, and maintenance-oriented services tied to rail and utility networks. On the other, Carbon Materials and Chemicals converts industrial byproducts into value-added inputs used in aluminum, steel, plastics, resins, rubber, and other manufacturing chains. This gives Koppers a niche industrial profile: it is not a broad commodity chemicals producer, but a technically specialized provider where process know-how, product stewardship, customer stickiness, and long-term supply relationships matter as much as headline scale.

From a competitive standpoint, Koppers benefits from global reach and from operating in segments that tend to have meaningful operational and regulatory barriers. The company emphasizes a diversified geographic footprint and a portfolio anchored in recurring infrastructure demand, allowing it to serve industrial and railroad customers across North America, Europe, Latin America, and other regions. Its differentiation comes from process expertise, byproduct valorization, and a sustainability-oriented operating model, all of which can help defend margins and customer relationships against more generalized competitors. ([koppers.com](https://www.koppers.com/company?utm_source=openai))
Recent developments include the release of the company’s 2024 annual report in March 2025 and its full-year 2025 results in early 2026. Those results highlighted changes in volumes and in certain chemical lines, including the discontinuation of phthalic anhydride production and lower revenues in some carbon and railroad maintenance activities. Koppers also continues to file Form 4 insider transaction disclosures, underscoring ongoing market attention to ownership activity and governance signals.
