PITTSBURGH, Nov. 7, 2025 /PRNewswire/ -- Koppers Holdings Inc. (NYSE: KOP), an integrated global provider of treated wood products, wood treatment chemicals, and carbon compounds, today reported its third quarter of 2025 results.

Chief Executive Officer Leroy Ball said, "Our team's continued discipline on controlling costs throughout the quarter – as driven by our Catalyst transformation process – led us to deliver operating performance in line with expectations.  However, with the exception of our utility pole business, end market softness persisted in the third quarter as expected. Although a higher-than-expected effective tax rate impacted bottom-line results, we turned our profitability into strong free cash flow generation and meaningful debt reduction.  In addition, we completed the sale of our Railroad Structures business in August, which further simplifies our business portfolio through the sale of a non-core business that has historically diluted our margins.  This divestiture, coupled with other personnel actions taken over the past 17 months, has reduced our global employee count by 17 percent from the high in April 2024."

Third Quarter Financial Performance

• RUPS net sales decreased due to $15.8 million of lower volumes from Class I crosstie customers and lower activity in its maintenance-of-way businesses, including the sale of its railroad bridge services business. These decreases were partly offset by higher volumes in commercial crossties, a 6.5 percent volume increase in the domestic utility pole business, and $1.9 million of price increases related primarily to crossties. Adjusted EBITDA increased due to $7.7 million of lower selling, general and administrative costs and operating expenses, and net sales price increases, partly offset by lower sales volumes.
• The decrease in PC net sales was the result of a 19 percent volume decrease primarily driven by a shift in U.S. market share, as well as a slight decrease in remaining customer volumes. Adjusted EBITDA decreased due to lower sales volumes and $7.3 million of higher raw material and operating costs, partly offset by $1.6 million of lower logistics costs and selling, general and administrative expenses, and higher royalty income.
• CMC net sales decreased mainly due to volume decreases of phthalic anhydride of $19.6 million as the company discontinued production, lower volumes and lower sales prices for carbon black feedstock, and lower sales prices for carbon pitch, which decreased approximately 3 percent globally. The decreases in carbon pitch prices were driven by market dynamics, particularly in Australasia. These decreases were partly offset by volume increases for carbon pitch and creosote. Adjusted EBITDA increased due to operating cost savings associated with ceasing phthalic anhydride production and $2.9 million of lower raw material costs, partly offset by lower sales prices.
• Operating cash flow for the nine months ending September 30, 2025 was $77.4 million, compared with $44.7 million in the prior year period. In the first quarter of 2025, the company paid $13.9 million related to the termination of its largest U.S. qualified pension plan.

Catalyst

In May 2025, Koppers announced a three-phase enterprise-wide transformation process, Catalyst, which involves the evaluation, scoping, quantification, planning, and execution of hundreds of commercial and cost saving opportunities through a rigorous process aimed at maximizing performance across every dimension of the organization. Having completed the first two phases focused on conducting an operational assessment and developing a detailed implementation plan that prioritizes initiatives based on impact and resource needs, the company has now entered the third and final multi-year phase of Catalyst. During this period, the company is actively executing initiatives and implementing identified opportunities to improve operational efficiency and financial performance.

Mr. Ball said, "The recently completed planning phase of our Catalyst transformation process has identified numerous actionable opportunities 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.  These initiatives, which we will implement over the next three years, impact all facets of the organization. As part of these efforts, we are focusing on growing the more profitable Performance Chemicals and Utility and Industrial Products businesses, while continuing to selectively scale back our lower margin, capital intensive Carbon Materials and Chemicals business. We believe that, by replacing lower margin business with higher value opportunities, we can grow earnings per share, on average by 10 percent annually, lower our annual maintenance and Zero Harm capital requirements, and consistently generate EBITDA margins above 15 percent by 2028. We are proud of the work our global team has put forth and look forward to realizing the tremendous opportunities ahead for Koppers as we execute the final phase of our transformation process."

2025 Outlook

After considering the expected shift in geography of earnings for 2025, which increased the company's effective tax rate and had an unfavorable impact of $0.05 on adjusted EPS in the third quarter, as well as the current competitive environment, global economic conditions, and ongoing uncertainty associated with geopolitical and supply chain challenges, Koppers is revising its sales forecast to be approximately $1.9 billion, compared with $1.9 billion to $2.0 billion previously. Accordingly, Koppers is tightening its 2025 financial forecast for adjusted EBITDA to be approximately $255 million to $260 million and adjusted EPS of approximately $4.00 to $4.15 per share.

The forecasted operating cash flow includes any impact from planned pension terminations and other special items. The company completed the termination of its largest U.S. qualified pension plan in February 2025, which required additional funding of $1.6 million in 2024 and $13.9 million in 2025.

Commenting on the revised forecast, Mr. Ball said, "I expect that we will finish the year within the middle part of our previously communicated adjusted EBITDA range.  Adjusted earnings per share will likely fall into the lower half of our previous range, primarily due to an unfavorable geographical mix of earnings, resulting in a higher-than-expected effective tax rate. On the plus side, free cash flow should be minimally impacted due to lower capital spending.  While challenging end markets, other than the utility pole sector, are expected to continue in the near-term, lower interest expense, a lower share count, and a more favorable tax rate in 2026 have us poised for meaningful earnings improvement and free cash flow generation."

Koppers does not provide reconciliations of guidance for adjusted EBITDA, adjusted EBITDA margin, and adjusted EPS to comparable GAAP measures, in reliance on the unreasonable efforts exception. Koppers is unable, without unreasonable efforts, to forecast certain items required to develop meaningful comparable GAAP financial measures. These items include, but are not limited to, restructuring and impairment charges, acquisition-related costs, mark-to-market commodity hedging, and LIFO adjustments that are difficult to forecast for a GAAP estimate and may be significant. Forward-looking statements, including the guidance above, are based upon current expectations and are subject to factors that could cause actual results to differ materially from those set forth above.

Non-GAAP Financial Measures

This press release contains certain non-GAAP financial measures. Koppers believes that adjusted EBITDA, adjusted net income attributable to Koppers, and adjusted earnings per share provide information useful to investors in understanding the underlying operational performance of the company, its business and performance trends, and facilitates comparisons between periods. The exclusion of certain items permits evaluation and a comparison between periods of results for ongoing business operations, and it is on this basis that Koppers management internally assesses the company's performance. In addition, the Board of Directors and executive management team use adjusted EBITDA as a performance measure under the company's annual incentive plans and for certain performance share units granted to management.

Although Koppers believes that these non-GAAP financial measures enhance investors' understanding of its business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP basis financial measures and should be read in conjunction with the relevant GAAP financial measure. Other companies in a similar industry may define or calculate these measures differently than the company, limiting their usefulness as comparative measures. Because of these limitations, these non-GAAP financial measures should not be considered in isolation or as substitutes for performance measures calculated in accordance with GAAP.

See the attached tables for the following reconciliations of non-GAAP financial measures included in this press release: Unaudited Reconciliation of Net Income to Adjusted EBITDA and Unaudited Reconciliations of Net Income Attributable to Koppers to Adjusted Net Income Attributable to Koppers and Diluted Earnings Per Share and Adjusted Earnings Per Share.
