Risks

• Availability of and fluctuations in the prices of key raw materials, including coal tar, lumber, and scrap copper.
• Impact of changes in commodity prices, such as oil, copper, and chemicals, on product margins.
• Economic, political, and environmental conditions in international markets, including governmental changes, tariffs, restrictions on trade, and restrictions on the ability to transfer capital across countries.
• Current and potential future tariffs or duties, including the 50% U.S. tariffs on semi-finished copper products, which could have a $10 million to $14 million impact on pre-tax profit over the next twelve months if not mitigated.
• The ratings on debt and the ability to repay or refinance outstanding indebtedness as it matures, and the ability to operate within debt covenants.
• Capital market and banking market conditions, including interest rates, borrowing costs, foreign currency rate fluctuations, and general volatility.
• General economic and business conditions, including labor shortages, increased employee turnover, and demand for goods and services.
• Disruptions and inefficiencies in the supply chain.
• Unexpected business disruptions (e.g., labor disputes, natural disasters, fires, unscheduled downtime, transportation interruptions, public health crises) and technology-related disruptions or failures (e.g., cyber attacks).
• Potential difficulties in protecting intellectual property.
• Potential delays in timing or changes to expected benefits from cost reduction efforts and transformation initiatives.
• Potential impairment of goodwill and/or long-lived assets.
• The effectiveness of commodity hedging programs, particularly with sustained and prolonged premiums of COMEX pricing over LME pricing for copper.
• Failure of parties obligated to indemnify for liabilities (e.g., Beazer East for environmental and legal liabilities) to perform under their legal obligations.
• Unfavorable resolution of litigation or other legal proceedings, including the Portland Harbor CERCLA site, Newark Bay CERCLA site, and the Stickney, IL air emissions enforcement matter.

Future Outlook

The company anticipates streamlining its organization to support a cost-conscious customer base, with actions expected to result in both one-time and permanent savings. A multi-year transformative project is underway, aiming to reshape the company into a higher earning, higher margin, higher free cash flow, and higher return on capital business over the next three years. This involves growing more profitable businesses and selectively scaling back lower margin, capital-intensive operations. Key focuses include recouping cost increases and expanding utility pole markets for RUPS, acquiring new residential customers and improving cost structure for PC, and executing plant restructuring and optimizing carbon products for CMC. The company expects the crosstie market to remain stable, utility pole demand to grow, and the PC business to see lower volumes due to market share shifts. The CMC business faces a slowdown in key industries and reduced coal tar supply, which it is mitigating with petroleum-blended products and distillation yield investments.

Management Comments

• "After considering the current intensely competitive environment, global economic conditions, as well as ongoing uncertainty associated with geopolitical and supply chain challenges, we anticipate taking measures to streamline our organization to support an increasingly cost-conscious customer base."
• "Through the planning phase that has occurred throughout 2025, we believe we have identified actionable transformation initiatives to position Koppers for future success, creating a roadmap to reshape our company into a higher earning, higher margin, higher free cash flow and higher return on capital business over the next three years."
• "We believe this will grow earnings per share, lower our maintenance and capital requirements and consistently generate higher margins."

Industry Context

Koppers operates in diverse end-markets including railroad, utility, specialty chemical, residential lumber, agriculture, aluminum, steel, rubber, and construction. The North American crosstie market is expected to remain stable (18-22 million ties annually), though total purchases for 2025 are projected to decrease. Utility pole demand is anticipated to grow due to aging infrastructure, renewable energy expansion, vehicle electrification, grid-hardening, extreme weather protection, and AI-driven electricity demand. The Performance Chemicals business is linked to consumer spending on home repair and remodeling, with the Leading Indicator of Remodeling Activity (LIRA) projecting modest growth in 2026. The Carbon Materials and Chemicals segment is affected by a slowdown in global manufacturing, steel, aluminum, and carbon black industries, which has reduced the availability of coal tar, a key raw material. The company is actively working to mitigate this by developing petroleum-blended products.

Comparison to Industry Standards

• Performance stock units are benchmarked against the Standard & Poors SmallCap 600 Materials Index.
• The Railway Tie Association estimates total crosstie purchases in 2025 at approximately 19.9 million ties, lower than 21.3 million in 2024, with North American demand historically ranging from 18 million to 22 million ties annually.
• The Leading Indicator of Remodeling Activity (LIRA) by the Joint Center for Housing Studies of Harvard University projects year-over-year spending for homeowner renovation and maintenance to grow by 2.4% in early 2026, easing to 1.9% in Q3 2026.

Key Dates

Recommendation

While Koppers Holdings reported a significant decline in nine-month net income and EPS, largely due to one-time pension settlement and restructuring charges, the company is actively engaged in a multi-year transformation aimed at improving profitability and margins. The RUPS and CMC segments showed Adjusted EBITDA growth, and the company maintains a healthy liquidity position and compliance with debt covenants. However, ongoing challenges include declining sales, market share shifts in the PC segment, raw material volatility, and new tariff impacts on copper. The stock repurchase program and dividend offer some shareholder value. A 'hold' recommendation is appropriate as the company navigates these transitions, with potential for long-term improvement balanced against near-term headwinds and execution risks.
