See Non-GAAP Financial Measures for additional information and reconciliations to the most directly comparable financial measure determined and reported in accordance with U.S. GAAP. • Net sales increased $15.3 million, or 3.0 percent, in the second quarter of 2026 as compared to the prior year quarter. Excluding the net unfavorable impact of 2025 acquisitions, divestitures, and product line rationalizations of $16.3 million and the favorable currency conversion effect of $6.7 million, net sales increased $24.9 million, or 5.1 percent, primarily driven by an increase in Performance Chemicals (PC) and utility pole volumes. The volume- driven increase was offset in part by unfavorable pricing and sales mix in the RUPS segment, when compared to the same period last year. • Adjusted EBITDA of $71.0 million decreased $6.1 million, or 7.9 percent, as compared to $77.1 million in the prior year quarter. This decrease was driven by higher raw material costs, unfavorable pricing in RUPS, higher freight and legal costs, and the impact of 2025 divestitures. These unfavorable changes were partly offset by lower operating costs and improved throughput from network optimization efforts. • Operating cash flow for the six months ended June 30, 2026, was a record $96.3 million compared to $27.8 million in the prior year period. The primary source of cash was net income excluding non-cash items, principally impairment, depreciation and in 2025, the pension settlement loss. Working capital usage improved in the current year primarily as a result of the timing of receipts and payments as well as a reduction in inventory. Additionally, in 2025, working capital was negatively impacted by pension funding of approximately $14 million in connection with the settlement. Free cash flow for the six months ended June 30, 2026, was $72.6 million, also a record, compared to $1.4 million in the prior year period, net of capital expenditures of $23.7 million and $26.4 million, respectively. • RUPS net sales decreased due to lower activity in maintenance-of-way businesses, including approximately $11.9 million related to the sale of its railroad services business during the third quarter of 2025, and price decreases across multiple markets, particularly for crossties, and unfavorable sales mix. These decreases were partly offset by a 16 percent volume increase in domestic utility poles, including an acquisition of a western U.S. pole procurement business, and increased volumes for crossties. Foreign currency changes had a favorable impact on sales in the quarter of $1.0 million compared to the prior year quarter, primarily from the Australian utility pole business. Adjusted EBITDA decreased due to net sales price decreases and unfavorable sales mix, higher raw material costs and lower activity in the maintenance-of-way businesses, including approximately $1.7 million related to the sale of the railroad services business. These decreases were partly offset by an increase in sales volume in the North American utility pole business. (1) 2

• PC net sales increased due to an 11 percent volume increase, primarily in the Americas, partly offset by lower prices, primarily in Europe. Foreign currency changes from international markets had a favorable impact on sales in the quarter of $2.2 million compared to the prior year quarter. Adjusted EBITDA increased due primarily to higher sales volumes and lower raw material costs of $1.3 million, partly offset by increased logistics expenses. Lower raw material costs were favorably impacted by the benefit realized from the company's copper-hedging program, net of increased scrap copper costs. • CMC net sales increased due mainly to volume and price increases for carbon black feedstock and volume increases for carbon pitch. These increases were partly offset by lower volumes of phthalic anhydride and refined tar as well as lower sales prices for carbon pitch, where prices were down approximately two percent globally. The decreases in carbon pitch prices were driven by market dynamics, particularly in Australasia. Foreign currency changes from international markets had a favorable impact on sales in the quarter of $3.5 million compared to the prior year quarter. Adjusted EBITDA decreased due to higher raw material, operating and selling, general and administrative expenses of $9.2 million, partly offset by the operating cost savings from discontinuing phthalic anhydride production at its facility in Stickney, Illinois. 2026 Outlook The company believes the current, more challenging margin environment will persist through the remainder of 2026, with overall profitability likely to be toward the lower end of previously stated guidance. Input costs and freight expenses are expected to remain headwinds. At the same time, several working capital initiatives are anticipated to generate additional cash flow, supporting the company's ability to maintain its cash flow guidance. Accordingly, Koppers is updating its 2026 forecast as follows: 2026 Current Forecast 2026 Prior Forecast 2025 Actual Net sales $1.9 - $2.0 billion $1.9 - $2.0 billion $1.9 billion Adjusted EBITDA $240 - $250 million $240 - $260 million $257 million Effective tax rate on adjusted net income 28 percent 28 percent 29 percent Adjusted EPS $3.80 - $4.20 $3.80 - $4.60 $4.07 Operating cash flow $165 - $185 million $165 - $185 million $123 million Capital expenditures $55 million $55 million $55 million Free cash flow $110 - $130 million $110 - $130 million $68 million Commenting on the 2026 forecast, Mr. Ball said, "We remain confident that our strategy and ongoing transformation initiatives position Koppers to unlock significant and sustainable improvements in earnings and cash flow. Our near-term priorities remain reducing debt and returning capital to shareholders, while continuing to execute a disciplined approach to long-term value creation." Koppers does not provide reconciliations of guidance for adjusted EBITDA, free cash flow 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. Please see the “Safe Harbor Statement” below for more information.

Non-GAAP Financial Measures This press release contains certain non-GAAP financial measures. Koppers believes that adjusted EBITDA, adjusted net income, free cash flow 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 prior to 2026. The Board of Directors and executive management also use free cash flow and adjusted earnings per share as performance measures for certain performance share units granted to management in 2026. 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, Unaudited Reconciliations of Net Income to Adjusted Net Income and Diluted Earnings Per Share and Adjusted Earnings Per Share and Unaudited Reconciliation of Net Cash Provided by (Used In) Operating Activities to Free Cash Flow. 4
