1. Business Overview

Koppers Holdings Inc. is a global producer of carbon compounds and treated wood products. The company operates three primary business segments:

• Railroad and Utility Products and Services (RUPS): Supplies essential infrastructure materials, including treated railroad ties, utility poles, and related services.
• Performance Chemicals (PC): Develops, manufactures, and markets wood preservatives and specialized chemicals for various industrial applications.
• Carbon Materials and Chemicals (CMC): Provides critical products like coal tar pitch, creosote, phthalic anhydride, and other carbon-based chemicals, serving industries such as aluminum, steel, and construction.

Koppers uses its expertise in material science and chemical processing to serve diverse industrial and infrastructure markets worldwide.

2. Financial Performance

Koppers delivered robust financial performance, showing consistent growth across key metrics.

• Revenue Growth: Total sales revenue steadily increased, rising from $1.41 billion in 2023 to $1.45 billion in 2024, and reaching $1.5 billion in 2025. This healthy 3-5% annual growth stemmed from both organic expansion and strategic acquisitions.
• Profitability: Koppers significantly improved its profitability. Net Income grew from $80 million in 2023 to $90 million in 2025, despite a temporary dip to $75 million in 2024 due to one-time restructuring costs. Earnings Per Share (EPS) reflected this trend, reaching $4.00 in 2023, $3.80 in 2024, and a strong rebound to $4.60 in 2025, reflecting effective cost management and share repurchases. Gross profit margins remained stable at approximately 25%, while operating income (EBITDA) consistently grew, reaching $165 million in 2025, up from $150 million in 2023.
• Segment Performance: All three core business segments contributed positively to the overall growth:
  • Railroad and Utility Products and Services (RUPS): Sales climbed from $700 million in 2023 to $750 million in 2025. This consistent increase highlights steady demand and Koppers' strong market position.
  • Performance Chemicals (PC): Sales grew from $330 million in 2023 to $350 million in 2025, benefiting from strategic acquisitions and stable demand.
  • Carbon Materials and Chemicals (CMC): Sales rose from $380 million in 2023 to $400 million in 2025, driven by industrial demand.
• Geographic Focus: Koppers' growth was predominantly driven by its domestic market:
  • United States: U.S. sales increased significantly, from $900 million in 2023 to $1 billion in 2025, representing a strong 5-6% annual growth and highlighting robust domestic demand.
  • International Markets: Sales in Australia, Europe, and other international regions remained stable, each contributing approximately $150-$200 million annually, providing diversification and a global footprint.
• Managing Costs: Selling, General, and Administrative (SG&A) expenses increased from $190 million in 2023 to $200 million in 2025. While growing in absolute terms, SG&A remained stable at approximately 13% of revenue, indicating controlled overhead relative to sales expansion.

3. Risk Factors

While Koppers shows strong performance, investors should be aware of potential risks that could materially affect its business, financial condition, and results of operations:

• Economic Cycles: Demand for Koppers' products ties to industrial activity and infrastructure spending, making it vulnerable to economic downturns and fluctuations in construction, railroad, and utility sectors.
• Commodity Price Volatility: Fluctuations in raw material costs (e.g., coal tar, wood, natural gas, crude oil) can significantly impact profitability, even with hedging efforts. Availability of key raw materials is also a concern.
• Environmental Regulations: As a chemical and materials company, Koppers faces ongoing and evolving regulatory scrutiny and potential costs for environmental compliance, remediation, and climate change initiatives. Non-compliance could lead to significant penalties.
• Competition: Operating in competitive markets across all segments could pressure pricing, market share, and margins. New entrants or technological advancements by competitors also pose a risk.
• Integration Risk: Successfully integrating recent acquisitions, such as Brown Wood Preserving Company Inc. and Greenhill Reload LLC, is crucial for realizing anticipated benefits and avoiding operational disruptions or higher-than-expected costs.
• Litigation and Legal Proceedings: The company may face various legal proceedings, including environmental, product liability, and other claims, potentially resulting in significant expenses or liabilities.
• Cybersecurity Risks: Koppers' dependence on information technology systems makes it vulnerable to cyberattacks, data breaches, or system failures. These could disrupt operations, compromise sensitive data, and incur significant costs.

4. Management Discussion and Analysis (MD&A) Highlights

Management's discussion highlights the strategic initiatives and operational decisions that drove Koppers' financial performance and position:

• Strategic Acquisitions: Management strategically expanded Koppers' market presence and capabilities through acquisitions.
  • Koppers acquired Brown Wood Preserving Company Inc. in April 2024 for approximately $40 million, strategically expanding its market share and product offerings within the Performance Chemicals segment and contributing to sales growth.
  • The recent acquisition of Greenhill Reload LLC in December 2025 for $25 million will enhance logistics and distribution capabilities for the RUPS segment, with its full financial impact expected in the upcoming fiscal year.
• Operational Restructuring: Koppers undertook significant restructuring efforts to improve efficiency and streamline operations.
  • Shutting down a Phthalic Anhydride plant in 2024-2025 incurred one-time costs of approximately $3 million annually for severance, asset disposal, and environmental remediation. This move aimed to divest non-core assets and focus on more profitable segments.
  • A workforce reduction program and consulting services each cost about $1 million annually in 2024 and 2025. These initiatives project annual cost savings of $8-10 million starting in 2026, which will improve future operating margins.
• Share Repurchase Program: Koppers repurchased approximately $20 million worth of its common stock over the past two years. This reduced outstanding shares by about 2% and contributed to EPS growth, signaling management's confidence in the company's valuation and commitment to returning capital to shareholders.
• International Joint Venture: The Koppers China Carbon Chemical Company Limited joint venture, formed in March 2023, continues to provide strategic access to growing Asian markets for carbon materials, though its financial contribution remains modest initially.
• Risk Management: Koppers actively uses derivative contracts to hedge against market volatility, specifically managing exposure to fluctuating interest rates and commodity prices (e.g., heating oil, coal tar). These instruments resulted in minor net gains/losses, demonstrating effective mitigation of potential financial risks from market swings and contributing to more stable operating results.

5. Financial Health

Koppers' financial foundation strengthened considerably, demonstrating robust liquidity and a prudent approach to capital structure.

• Balance Sheet Strength: Total equity increased from $617.9 million in 2023 to $666.7 million in 2025, primarily fueled by retained earnings. Koppers also prudently managed its debt, reducing total debt from $500 million in 2023 to $480 million in 2025, which improved its debt-to-equity ratio to approximately 0.7x. This indicates a healthy leverage position and capacity for future investment.
• Cash Flow Generation: Koppers generated strong Cash Flow from Operations (CFO), reaching $130 million in 2025, up from $120 million in 2023. This robust cash generation allowed Koppers to fund capital expenditures (CAPEX of approximately $70 million in 2025), execute strategic acquisitions, and return capital to shareholders through share buybacks, all while maintaining a healthy cash balance of $60 million in 2025.
• Liquidity: Koppers' strong cash flow and manageable debt levels provide ample liquidity to meet short-term obligations, fund ongoing operations, and pursue strategic growth opportunities. Its cash balance and access to credit facilities further support its financial flexibility.

6. Future Outlook

Koppers management projects continued growth for the upcoming fiscal year, anticipating revenue in the range of $1.55 billion to $1.6 billion and EPS between $4.80 and $5.10. Management plans to focus on:

• Leveraging recent acquisitions to drive synergies, expand product offerings, and enhance market penetration.
• Realizing cost savings from completed restructuring initiatives, which should significantly improve operating margins starting in 2026.
• Investing approximately $75 million in capital expenditures (CAPEX) for maintenance, operational efficiency improvements, and strategic growth projects, including sustainability initiatives across its facilities.
• Expanding its product portfolio in performance chemicals and sustainable wood treatment solutions, aligning with market trends and customer demand for environmentally friendly products.
• Optimizing its global footprint and supply chain to improve efficiency and responsiveness to market changes.

7. Competitive Position

Koppers operates in specialized industrial markets where its competitive position is generally strong due to its integrated operations, technical expertise, and established customer relationships.

• Market Leadership: Koppers holds leading positions in several core product categories, particularly within the treated wood products and carbon materials segments. For instance, its RUPS segment benefits from its role as a primary supplier of essential infrastructure materials.
• Specialized Products and Services: Koppers differentiates itself with specialized product formulations, technical support, and comprehensive service offerings, all critical for its industrial customers.
• Barriers to Entry: The capital-intensive nature of its manufacturing processes, extensive regulatory compliance requirements, and technical product complexity create significant barriers to entry for potential competitors.
• Integrated Supply Chain: Koppers' integrated business model, from raw material sourcing to finished product distribution, provides cost efficiencies and supply reliability, enhancing its competitive advantage.
• Global Presence: Its global operational footprint allows Koppers to serve diverse markets and mitigate regional economic fluctuations.
• Innovation: Ongoing investment in research and development helps Koppers maintain its technological edge and develop new products and solutions.
