Koppers Holdings Inc. reported fourth‑quarter 2025 results on February 26, 2026, showing net sales of $432.7 million, a 9.3% decline from $477.0 million a year earlier, and a net income of $29.7 million, a turnaround from a $10.2 million loss in 2024. Adjusted earnings per share rose to $0.70, beating the consensus estimate of $0.59 by $0.11 (18.6%). Adjusted EBITDA for the quarter was $53.2 million, slightly lower than the $55.2 million reported in Q4 2024.

The Q4 EPS beat was driven by disciplined cost management and the ongoing Catalyst transformation program, which delivered $46 million in benefits during 2025. Catalyst’s focus on operational efficiency and margin expansion in the Railroad and Utility Products segment helped offset softer demand in the Performance Chemicals and Carbon Materials segments, allowing the company to maintain a 12.3% EBITDA margin on sales.

Revenue missed expectations, falling $11.8 million (2.66%) below the consensus estimate of $444.5 million. The miss reflects weaker demand in the Performance Chemicals and Carbon Materials segments, where raw‑material cost pressures and competitive pricing eroded sales, while the Catalyst program’s cost‑saving initiatives mitigated the impact on profitability.

Full‑year 2025 results showed net sales of $1.879 billion, down 10.2% from $2.09 billion in 2024, and adjusted EBITDA of $256.7 million, a 4.9% decline but still a record 13.7% margin. The Catalyst program’s $46 million benefit contributed to the margin expansion, making 2025 the second‑highest year on record for adjusted EBITDA margin.

Management guided for 2026 net sales of $1.9‑$2.0 billion, adjusted EBITDA of $250‑$270 million, and adjusted EPS of $4.20‑$5.00. The guidance reflects confidence in a modest sales recovery, continued Catalyst benefits of $20‑$40 million, and a focus on debt reduction and capital return, with operating cash flow expected to reach $150‑$170 million.

Segment analysis shows the Railroad and Utility Products segment drove margin expansion, while the Performance Chemicals segment experienced a decline in sales due to softer demand and higher copper prices. The Carbon Materials segment also faced headwinds, but Catalyst‑driven cost efficiencies helped maintain profitability across the business.

Investors reacted positively to the earnings release, citing the EPS beat and the optimistic 2026 guidance as key drivers of confidence. The company’s ability to deliver a margin expansion despite a revenue decline reinforced investor belief in the effectiveness of the Catalyst program.

CEO Leroy M. Ball noted, "We achieved adjusted EBITDA of $256.7 million and a 13.7% adjusted EBITDA margin for 2025, describing it as the second highest year on record, and highlighted $4.07 in adjusted EPS, marking the sixth consecutive year above $4." Interim CFO Bradley Pearce added, "Adjusted EBITDA for the fourth quarter was $53 million, which represents a 12.3% EBITDA margin on sales."

Headwinds for 2026 include continued softness in the Performance Chemicals and Carbon Materials segments, higher raw‑material costs, and competitive pricing pressure. Tailwinds are the ongoing Catalyst program, growing demand for utility products driven by AI infrastructure and electric‑vehicle charging, and a strategic focus on debt reduction and capital return. The company’s guidance and management commentary suggest a cautious but optimistic outlook for the next fiscal year.
