Overview

We are a leading integrated global provider of treated wood products, wood preservation chemicals and carbon compounds. Our products and services are used in a variety of niche applications in a diverse range of end-markets, including the railroad, specialty chemical, utility, residential lumber, agriculture, aluminum, steel, rubber and construction industries. We serve our customers through a comprehensive global manufacturing and distribution network, with manufacturing capabilities in North America, South America, Australasia and Europe. We operate three principal businesses: RUPS, PC and CMC.

Through our RUPS business, we believe that we are the largest supplier of railroad crossties to the Class I railroads in North America and the second largest producer of utility poles in the United States. Our utility poles are used in the electric, telephone, and broadband industries in the United States and Australia and construction pilings in the United States. In addition, we provide untreated wood products and rail joint bars to the railroad markets. We also operate a business related to the recovery of used crossties, serving the same customer base as our North American railroad business.

Through our PC business, we believe that we are the global leader in developing, manufacturing and marketing wood preservation chemicals and wood treatment technologies for use in the pressure treating of lumber for residential, industrial and agricultural applications.

21

Our CMC business processes coal tar into a variety of products, including creosote, carbon pitch, carbon black feedstock and naphthalene, which are intermediate materials necessary in the pressure treatment of wood, and the production of aluminum, steel, carbon black and high-strength concrete. See Note 2 - Restructuring for further discussion of the discontinuation of distillation and chemical manufacturing operations in Stickney, Illinois.

Non-GAAP Financial Measures

We utilize certain financial measures that are not in accordance with U.S. GAAP to analyze and manage the performance of our business. We believe that adjusted EBITDA provides information useful to investors in understanding the underlying operational performance of the company, our business and performance trends, and facilitates comparisons between periods. The exclusion of certain items permits evaluation and a comparison between periods of results for business operations, and it is on this basis that our management internally assesses our performance. Adjusted EBITDA is the measure of profitability we use to evaluate our businesses. In addition, adjusted EBITDA is the primary measure used to determine the level of achievement of management's short-term incentive goals and related payout, as well as one of the measures used to determine performance and related payouts for certain performance share units granted to management prior to 2026.

Adjusted EBITDA is a non-GAAP financial measure defined as income before interest expense, income taxes, depreciation, amortization and other adjustments. These other adjustments are items that we believe are not representative of underlying business performance. Adjusted items typically include LIFO inventory effects, impairment, restructuring and plant closure costs, significant gains and losses on asset disposals or business combinations, mark-to-market commodity hedging, acquisition-related charges, cloud-computing amortization expenses and other unusual items. The LIFO expense adjustment removes the entire impact of LIFO and effectively reflects the results as if we were on a FIFO inventory basis. An adjusted EBITDA reconciliation is presented in the Segment Results section and reconciles net income to adjusted EBITDA on a consolidated basis.

Although we believe adjusted EBITDA enhances investors’ understanding of our business and performance, this non-GAAP financial measure should not be considered an alternative to GAAP financial measures and should be read in conjunction with the relevant GAAP financial measures. Other companies in a similar industry may define or calculate this measure differently than we do, limiting its usefulness as a comparative measure. Because of these limitations, this non-GAAP financial measure should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.

Outlook

Forward-looking statements, including the significant market indicators described below, are based upon current expectations and are subject to factors that could cause actual results to differ materially from those set forth below. Please see the “forward-looking statements” disclaimer in the above section for more information.

After considering the current intensely competitive environment, global economic conditions, as well as ongoing uncertainty associated with geopolitical and supply chain challenges, we commenced taking measures to streamline our organization to support an increasingly cost-conscious customer base. These actions, some of which are one-time savings and some of which are expected to be permanent savings, are intended to ensure that we grow our profitability and support a higher margin profile by leveraging a smaller global team highly focused on serving customer preferences. Through the planning phase that occurred throughout 2025, we believe we have identified actionable transformation initiatives 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 by the end of 2028. These initiatives impact all facets of the organization and are focused on growing the more profitable businesses while continuing to selectively scale back our lower margin, capital intensive business. We believe this will grow earnings per share, lower our maintenance and capital requirements and consistently generate higher margins.

Significant areas of focus include:

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

Non-GAAP Financial Measures

We utilize certain financial measures that are not in accordance with U.S. generally accepted accounting principles (U.S. GAAP) to analyze and manage the performance of our business. We believe that adjusted EBITDA provides information useful to investors in understanding the underlying operational performance of the company, our business and performance trends, and facilitates comparisons between periods.

Outlook

Forward-looking statements, including the guidance below, are based upon current expectations and are subject to factors that could cause actual results to differ materially from those set forth below. Please see “Forward-Looking Statements” and "Risk Factors" for more information.

After considering the current intensely competitive environment, global economic conditions, as well as ongoing uncertainty associated with geopolitical and supply chain challenges, we commenced taking measures to streamline our organization to support an increasingly cost-conscious customer base. These actions, some of which are one-time savings and some of which are expected to be permanent savings, are intended to ensure that we grow our profitability and support a higher margin profile by leveraging a smaller global team highly focused on serving customer preferences. Through the planning phase that occurred throughout 2025, we believe we have identified actionable transformation initiatives 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 over the next three years. These initiatives impact all facets of the organization and are focused on growing the more profitable businesses while continuing to selectively scale back our lower margin, capital intensive business. We believe this will grow earnings per share, lower our maintenance and capital requirements and consistently generate higher margins.

Significant areas of focus include:

•For our RUPS segment, our focus is to continue to (i) recoup cost increases, including the value of our creosote preservative in the market, (ii) maximize opportunities for increased volumes, including expanding our customer base in the midwestern and western utility pole markets and (iii) lower operating and selling, general and administrative expenses.

•For our PC segment, our focus is to continue to (i) acquire new customers and grow organic market share in our residential preservatives markets (ii) expand market share in our industrial preservatives markets and (iii) align and improve our cost structure.

•For our CMC segment, our focus is to continue to (i) execute on domestic plant restructuring projects, (ii) optimize and develop markets for enhanced carbon products and (iii) develop and implement global tar and pitch strategies to mitigate expected raw material cost increases.

Significant market indicators for our businesses include:

•The Railway Tie Association’s estimate of total crosstie purchases in 2026 is approximately 19.9 million ties, with approximately 13.3 million for Class I railroads. This is comparable to the 2025 estimate of crosstie purchases of approximately 19.9 million crossties. Over the past few years, North American demand for crossties has been in the range of 18 million to 22 million crossties annually. We expect the crosstie market to remain stable and within this range. However, volumes for our business in any year can be affected by individual customer demands, logistics and business conditions.

•Market demand for utility poles is expected to grow over the next few years. The main driver for growth is the construction of datacenters that support artificial intelligence development. The datacenters that are being constructed nationwide consume large amounts of electricity. Other drivers of pole demand include aging pole infrastructure, the expansion of renewable energy, vehicle electrification, grid-hardening measures, and extreme weather protection. Our Utility Products business continues to focus on expanding its presence in the midwestern and western United States.

•Product demand for our PC business has historically been associated with consumer spending on home repair and remodeling projects in North America. The Leading Indicator of Remodeling Activity (LIRA) reported by the Joint Center for Housing Studies of Harvard University projects that year-over-year spending for annual homeowner renovation and maintenance expenditures is expected to grow by 2.9 percent in early 2026 before easing to 1.6 percent by the end of 2026. Our PC business expects higher volumes through market share growth and acquiring new customers supported by the LIRA projections.

•For the external markets served by our CMC business, we have experienced a slowdown in manufacturing overall as well as in the steel, aluminum and carbon black industries. The availability of coal tar, the primary raw material for our CMC business, is linked to levels of metallurgical coke production. As the global steel industry, excluding Asia, has reduced the production of steel using metallurgical coke, the volumes of coal tar have been reduced. We are actively working to mitigate the impacts of the long-term decline of coal tar supply by gaining market acceptance for petroleum-blended products. We are also investing in projects to increase distillation yields and balance raw material supply and cost with customer demand and pricing.

Our businesses and results of operations are affected by various competitive and other factors including (i) the impact of global economic conditions on demand for our products, including the impact of imported products from competitors in certain regions where we operate as well as tariffs and international trade policy; (ii) raw material pricing and availability, in particular the cost and availability of hardwood lumber for railroad crossties, softwood lumber for utility poles, scrap copper prices, and the cost and amount of coal tar available in global markets, which is negatively affected by reductions in blast furnace steel production; (iii) volatility in oil prices, which impacts the cost of coal tar and certain other raw materials, as well as selling prices and margins for certain of our products including carbon black feedstock and naphthalene; (iv) competitive conditions in our performance chemicals business and global carbon pitch markets; (v) the effectiveness of our commodity hedging programs; (vi) changes in foreign exchange rates; and (vii) the other factors set forth in the "Forward-Looking Statements" disclaimer. Any or all of these or other factors could impact our actual results.

Recent Developments

In February 2026, we made the decision to idle production activities at our Utility and Industrial Products facility in Vance, Alabama, effective immediately. Substantially all production handled at this location was transitioned to our Kennedy, Alabama plant. These facilities were located within 60 miles of each other and served the same market which resulted in plant underutilization, redundancy and higher operating costs.

In February 2026, we also announced our plan to idle production activities at our Railroad Products and Services facility in Florence, South Carolina due to lower overall future forecasted demand from the facility's largest customer. We expect to ramp down production at Florence over the next several months with plant idling activities to be completed by November 2026. During this time period, we will transition incremental production to our facility in Guthrie, Kentucky.

Consolidating production of these facilities will help us optimize our network, better align capacity with demand, reduce operating costs and strengthen the long-term competitiveness of our operations.

Trade Tariff Uncertainties

Our outlook reflects plans to substantially offset costs related to import and export tariffs, where possible, but there is continued uncertainty regarding the implementation dates and scope of potential additional tariffs, as well as potential retaliatory trade policy. As a result of these items, our outlook may vary. See also Item 1A. Risk Factors in this Form 10-K.

Seasonality and Effects of Weather on Operations

Our quarterly operating results fluctuate due to a variety of factors that are outside of our control, including inclement weather conditions, which in the past have affected operating results. Operations at some of our facilities have at times been reduced during the winter months. Moreover, demand for some of our products declines during periods of inclement weather. As a result of the foregoing, we anticipate that we may experience material fluctuations in quarterly operating results. Historically, our operating results have been significantly lower in the first and fourth calendar quarters as compared to the second and third calendar quarters.
