Environmental Compliance and Litigation Risks: Koppers faces significant exposure to environmental regulations and potential liabilities from past and present operations, including remediation costs and fines for non-compliance.

Raw Material Price and Supply Volatility Risks: The company's profitability is sensitive to fluctuations in the cost and availability of key raw materials like coal tar, creosote, and other chemicals, which can be impacted by market dynamics, geopolitical events, or supplier disruptions.

Economic Downturn and Market Demand Sensitivity Risks: Demand for Koppers' products is closely tied to the health of the industrial, infrastructure, and construction sectors, making the company vulnerable to economic downturns, reduced government spending, or shifts in these markets.
