Material Changes vs. Prior Period
- Restructuring Charges: The primary driver of the net loss was a $215.8 million impairment and restructuring charge in Q2 2026 (compared to $17.6 million in Q2 2025). This includes a $164.6 million impairment related to the Stickney, Illinois facility shutdown, along with severance, demolition, and consulting costs.
- Segment Performance:
- RUPS: Net sales decreased 1.8% QoQ due to price decreases and the prior-year sale of the railroad services business, partially offset by a 16% volume increase in utility poles.
- PC: Net sales increased 11.5% QoQ driven by an 11% volume increase, primarily in the Americas.
- CMC: Net sales increased 2.3% QoQ, driven by volume and price increases in carbon black feedstock, offset by lower phthalic anhydride volumes and lower carbon pitch prices.
- Cost Structure: Cost of sales as a percentage of net sales increased to 79% in Q2 2026 from 77% in Q2 2025, driven by higher raw material and freight costs.
Outlook, Risks, and Management Commentary
Management Outlook: Management is focused on a transformation roadmap to reshape the company into a higher-margin, higher free cash flow business by 2028. Key initiatives include streamlining the organization, optimizing the network to align capacity with demand, and selectively scaling back lower-margin, capital-intensive businesses. The Stickney facility shutdown is expected to be completed by December 31, 2026.
Market Indicators:
- RUPS: Crosstie demand is expected to remain stable (18-22 million ties annually). Utility pole demand is expected to grow, driven by data center construction and grid expansion.
- PC: Home renovation spending growth is projected to be modest (0.5% YoY in Q1 2027), but the company expects volume growth through market share gains.
- CMC: The company faces a long-term decline in coal tar supply due to reduced metallurgical coke production globally. They are mitigating this by developing petroleum-blended products.
Risks and Contingencies:
- Environmental Litigation: The company is a potentially responsible party (PRP) at the Portland Harbor and Newark Bay CERCLA sites. While Koppers believes it is a de minimis contributor, cost allocations are ongoing. An estimated liability of $3.8 million is accrued for these sites.
- Regulatory Action: The Illinois Attorney General filed a complaint regarding air emissions violations at the Stickney facility. The company has accrued an estimated liability for the probable penalty.
- Commodity Volatility: Results are sensitive to fluctuations in coal tar, lumber, scrap copper, and oil prices.
Investor Verification Checklist
- Restructuring Execution: Verify the timeline and cost realization of the Stickney, Illinois shutdown and the idling of the Vance, Alabama and Florence, South Carolina facilities.
- CMC Raw Material Supply: Monitor the company's progress in mitigating the long-term decline of coal tar supply and the market acceptance of petroleum-blended products.
- Environmental Liabilities: Track the resolution of the Portland Harbor cost allocation process and the outcome of the Illinois Attorney General's enforcement action.
- Debt Covenants: Confirm continued compliance with the Credit Facility covenants, particularly the net leverage ratio, given the significant restructuring charges impacting EBITDA.
- Utility Pole Growth: Assess the sustainability of the volume growth in the utility pole business driven by data center infrastructure expansion.
