Koppers Holdings Inc. was incorporated in November 2004 as a holding company for Koppers Inc.

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.

Business Segments and Products

We operate three principal business segments: Railroad and Utility Products and Services (“RUPS”), Performance Chemicals (“PC”) and Carbon Materials and Chemicals (“CMC”).

We believe our three business segments command leading market positions. Through our RUPS business, we believe that we are the largest supplier of railroad crossties to the Class I railroads in North America. Through our CMC business, we believe we are the largest global supplier of creosote to the North American railroad industry. 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.

Our RUPS and CMC operations are, to a substantial extent, vertically integrated. Through our CMC business, we process coal tar into a variety of products, including creosote, which is an intermediate material necessary in the pressure treatment of wood crossties and other related railroad products. The majority of the creosote we produce in North America and Europe is sold internally to our RUPS business for treating railroad crossties.

Our RUPS and PC operations are also vertically integrated. Through our PC business, we produce a variety of products, including chromated copper arsenate, which is used in the pressure treatment of utility poles and pilings. A portion of the chromated copper arsenate we produce in North America and Australia is sold internally to our RUPS business for treating poles and pilings.

Railroad and Utility Products and Services

Our RUPS business sells treated and untreated wood products, rail joint bars and services primarily to the railroad markets in the United States and Canada and the utility markets in the United States and Australia. We also operate a railroad services business that conducts engineering, design, repair and inspection services for railroad bridges and a business related to the recovery of used crossties, serving the same customer base as our North American railroad business.

Railroad products and services include procuring and treating items such as crossties, switch ties and various types of lumber used for railroad bridges and crossings. Railroad products also include manufacturing and selling rail joint bars, which are steel bars used to join rails together for railroads. Utility products, located in the United States and Australia, include the pressure treatment of transmission and distribution poles for electric and telephone utilities. The RUPS business operates 20 wood treating plants and one rail joint bar manufacturing facility located throughout the United States, Canada and Australia. Our network of plants is strategically located near timber supplies to enable us to access raw materials and service customers effectively. In addition, our crosstie treating plants are typically adjacent to our largest railroad customers’ rail lines.

Our RUPS business manufactures its primary products and sells them directly to our customers through long-term contracts and purchase orders negotiated by our regional sales personnel and coordinated through our marketing group at corporate headquarters.

Hardwoods, such as oak and other species, are the major raw materials in wood crossties. Hardwood prices, which account for more than 50 percent of a finished crosstie’s cost, fluctuate with the demand from other hardwood lumber markets, such as oak flooring, pallets and other specialty lumber products. Weather conditions can be a factor in the supply of raw material, as unusually wet or inclement conditions may make it difficult to harvest timber.


Koppers Holdings Inc.     2020 Annual Report

In the United States, hardwood lumber for crossties is procured by us from hundreds of small sawmills throughout the northeastern, midwestern and southern areas of the country. The crossties are shipped via rail car or trucked directly to one of our crosstie treating plants, all of which are on line with a major railroad. The crossties are either air-stacked for a period of six to nine months or artificially dried by a process called boultonizing. Once dried, the crossties are pressure treated with creosote, a product of our CMC business. A substantial portion of our crossties are treated with borate, which is purchased from PC, in combination with creosote.

We believe we are the largest supplier of railroad crossties to the Class I railroads in North America. We have one principal competitor, Stella-Jones Inc., and several smaller regional competitors in the North American market. Competitive factors in the railroad crosstie market include price, quality, location, service and security of supply. We believe we have a competitive advantage due to our ability to obtain internally-sourced creosote and our national network of treating plants which have direct access to our major customers’ rail lines. These advantages provide for security of supply and logistics advantages for our customers.

Our RUPS business’ largest customer base is the North American Class I railroad market, which buys approximately 74 percent of all crossties produced in the United States and Canada. Approximately 72 percent of our North American RUPS sales are under long-term contracts and we currently supply all North American Class I railroads. We also have relationships with many of the approximately 600 short-line and regional rail lines. This also forms the customer base for our rail joint bar products. The railroad crosstie market trended lower in 2020, with approximately 18.7 million replacement crossties purchased during the year, up from 18.5 million and down from 21.2 million purchased during 2019 and 2018, respectively.

Demand for railroad crossties may decline during winter months due to inclement weather conditions which make it difficult to harvest lumber and to install railroad crossties. As a result, operating results may vary from quarter to quarter depending on the severity of weather conditions and other variables affecting our products.

We believe our North American utility pole business is the second largest producer of utility poles in the United States, and we believe our Australian utility pole business is the largest producer of utility poles in Australia. Utility poles are produced mainly from pine species in the United States and the eucalyptus species in Australia. Most of these poles are purchased from large timber owners and individual landowners and shipped to one of our pole-peeling facilities. In North America and Australia, in addition to utility poles, we market pilings for marine applications and smaller poles to the agricultural landscape and vineyard markets. We treat poles with a variety of preservatives, including chromated copper arsenate and creosote, which we produce internally and purchase from PC and CMC, respectively, and pentachlorophenol, which we purchase from an outside supplier. It is expected that the only North American manufacturer of pentachlorophenol will permanently cease production by the end of 2021. Accordingly, it is expected that utility pole treaters who utilize pentachlorophenol will convert to another accepted treatment preservative over the next 10 months.

Performance Chemicals

Our PC business maintains sales and manufacturing capabilities in the United States, Canada, Europe, South America, Australia and New Zealand. The primary products supplied by PC are copper-based wood preservatives, including micronized copper azole (“MicroPro®”), micronized pigments (“MicroShades®”), alkaline copper quaternary, amine copper azole and chromated copper arsenate. The primary applications for these products include decking, fencing, utility poles, construction lumber and timbers, and various agricultural uses. Additionally, we are a leading supplier of fire-retardant chemicals (“FlamePro®”) for pressure treatment of wood, primarily in commercial construction, where applicable. Because we are a global supplier of wood preservatives, we face various competitors in all the geographic regions in which we participate.   

PC supplies six of the ten largest lumber treating companies in the United States, the largest treated wood market in the world, in addition to the two largest lumber treating companies in Canada. In North America, our PC business is vertically integrated through the manufacturing of copper compounds for our copper-based wood preservatives. We purchase over 33 million pounds of scrap copper, in addition to other compounds containing copper, our key raw material, which we process to meet the annual demand of this major market. When we purchase scrap copper, it is shipped to our manufacturing plants in Hubbell, Michigan and Millington, Tennessee for further processing into other copper compounds. We utilize swap contracts to hedge our exposure to copper price risk.

We believe that being vertically integrated in copper manufacturing provides PC with an important competitive advantage and also provides our customers with the security of a continuous supply of wood preservatives. Likewise, we believe that our marketing, engineering, and technical support services provide added value to our customer base, who supply pressure-treated wood products to large retailers and independent lumber dealers. We believe another competitive advantage is provided by our strategic sourcing group, which procures scrap copper and other raw materials, such as chromic acid, tebuconazole, arsenic trioxide, colorants, dispersants and various biocides and co-biocides through the global market. 



Carbon Materials and Chemicals

Our CMC business manufactures its primary products and sells them directly to our global customer base under long-term contracts or through purchase orders negotiated by our regional sales personnel and coordinated through our regional marketing groups. Our three coal tar distillation facilities and five carbon materials terminals give us the ability to offer customers multiple sourcing options and a consistent supply of high-quality products.

For much of the past decade, the coal tar distillation industry has operated in an excess capacity mode, which further increased the competition for a limited amount of coal tar in North America and Europe. In 2014, we embarked on a plan to restructure our CMC operating footprint that reduced our global number of coal tar distillation facilities from the 11 that existed as of January 1, 2014 to three in total as of December 31, 2020. In September 2020, we sold our remaining Chinese distillation facility in operation, Koppers (Jiangsu) Carbon Chemical Company Limited (“KJCC”) located in Pizhou, Jiangsu Province as discussed in “Note 4 – Plant Closures and Discontinued Operations”.

Our CMC business has experienced challenges over the past several years due to the closure of aluminum smelters that has occurred in North America, Western Europe and Australia. The smelting of aluminum requires significant amounts of energy, which is a major cost component for the aluminum industry. As a result, new production facilities are being built in regions with low energy costs such as the Middle East, while regions with higher energy costs such as North America, Western Europe and Australia have seen significant amounts of smelting capacity idled or closed over the last several years.

Our CMC business manufactures the following principal products:


creosote, used in the treatment of wood or as a feedstock in the production of carbon black;


carbon pitch, a critical raw material used in the production of aluminum and steel;


naphthalene, used as a feedstock in the production of phthalic anhydride and as a surfactant in the production of concrete, and


phthalic anhydride, used in the production of plasticizers, polyester resins and alkyd paints, respectively.

Creosote, carbon pitch, naphthalene, and carbon black feedstock are produced through the distillation of coal tar, a by-product generated through the processing of coal into coke for use in steel and iron manufacturing. Coal tar distillation involves the conversion of coal tar into a variety of intermediate chemical products in processes beginning with distillation. During the distillation process, heat and vacuum are utilized to separate coal tar into three primary components: chemical oils, distillate and carbon pitch.

In the United States, our primary coal tar raw material supply contracts generally have terms ranging from three to ten years, and most provide options for renewal. Pricing under these contracts is either formula-based or negotiated on a quarterly or semi-annual basis. Our primary European tar supply contract has a remaining term of approximately five years, extending indefinitely thereafter unless terminated by a one-year advance notice, and contains formula-based tar pricing. Finally, our primary Australian supply contracts have terms ranging from three to ten years and contain formula-based pricing which is adjusted on an annual or semi-annual basis.

Technology and Licensing

In 1988, we acquired the “Koppers” trademark from Koppers Company, Inc. The association of the name with the chemical, building, wood preservation and coke industries is beneficial to our company, as it represents long-standing, high quality products. Trademarks relating to our PC business, such as “MicroPro®”, “FlamePro®”, “Protim” and “Solignum” are important in this segment of our business, and as long as we continue to use the name “Koppers” and the trademarks associated with our wood preservation business and comply with applicable registration requirements, our right to use the name “Koppers” and the other trademarks should continue without expiration. The expiration of other trademark rights is not expected to materially affect our business.


Generally, Koppers does not manufacture its products against a backlog of orders. Inventory and production levels are typically driven by expectations of future demand based on contractual obligations. Our RUPS business carries significant amounts of untreated crosstie inventory, which typically requires air-seasoning for a period of six- to nine-months.


Demand for residential, commercial, and agricultural treated lumber may decline during winter months due to weather conditions. In addition, inclement or winter weather may affect access to certain raw materials or impact operations at our facilities. As a result, operating results may vary from quarter to quarter depending on the severity of weather conditions and other variables affecting our products.  Historically, our operating results have been significantly lower in the first and fourth calendar quarters as compared to the second and third calendar quarters.

Segment Information

Please see Note 9, “Segment Information,” under Item 8 of this Form 10-K for financial information relating to business segments and geographic areas. See also “Item 1A. Risk Factors – Risks Related to Our Business – Demand for our products is cyclical and we may experience prolonged depressed market conditions for our products.”

Non-U.S. Operations

Koppers has a significant investment in non-U.S. operations. Therefore, we are subject to certain risks that are inherent to foreign operations, including complying with applicable laws relating to foreign practices, the laws of foreign countries in which we operate, political and economic conditions in international markets, the imposition of tariffs and fluctuations in foreign exchange rates. See also “Item 1A. Risk Factors – Risks Related to Our Business – We are subject to risks inherent in foreign operations, including additional legal regulation, changes in social, political and economic conditions.”

Environmental Matters

Our operations and properties are subject to extensive federal, state, local and foreign environmental laws and regulations relating to protection of the environment and human health and safety, including those concerning the treatment, storage and disposal of wastes, the investigation and remediation of contaminated soil and groundwater, the discharge of effluents into waterways, the emission of substances into the air, as well as various health and safety matters. Environmental laws and regulations are subject to frequent amendment and have historically become more stringent over time. We have incurred and could incur in the future significant costs if we fail to comply with regulations and responsibilities under environmental laws and regulations, including cleanup costs, civil and criminal penalties, injunctive relief and denial or loss of, or imposition of significant restrictions on, environmental permits. In addition, we have been and could in the future be subject to suit by private parties in connection with alleged violations of, or liabilities under, environmental laws and regulations. Additional information on environmental matters is available in Item 1A under “Risks Related to Our Business” and Note 19 of the Notes to Consolidated Financial Statements, “Commitments and Contingent Liabilities.”

Employees and Employee Relations

As of December 31, 2020, we had 921 salaried employees and 1,140 non-salaried employees. Listed below is a breakdown of employees by our businesses, including administration.












Railroad and Utility Products and Services













Performance Chemicals













Carbon Materials and Chemicals


























Total Employees














Approximately 648 of our employees are represented by a number of different labor unions and are covered under numerous labor agreements. The labor contracts at two of our facilities covering approximately 236 employees are scheduled to expire during 2021.

Human Capital Management

Our ability to positively affect our communities starts with investing in our people. We put the health, safety and well-being of our employees at the forefront of everything we do as part of our Zero Harm culture. Our people-focused strategy considers all aspects of the employee experience, from hiring practices and onboarding to health and wellness and talent management. We seek to create and foster an inclusive and welcoming culture where all employees feel empowered and can directly impact and share in the organization’s success. Key to this effort is delivering a consistent onboarding experience, as well as communications and safety training in all of our facilities across the globe.

Our decision-making considers the impact our actions may have on our employees and for each action we take, protecting employee health and well-being is our priority. To accomplish all this, and to better reflect the importance of our employees, we recently transformed our human resources function into a Culture and Engagement team to enhance the employee experience. This transformation is a reflection of how we approach our corporate culture, and how we engage with and support our employees both at work and in other aspects of their lives.



Talent Attraction and Retention

Our talented employees are a critical element to make our business successful, so it is essential that we position them for success as well. It is also important that we continue attracting top talent to our workforce. Our Culture and Engagement team leads these efforts to attract, retain and develop our employees and has created various programs to enhance the skill set of our workforce. Recognizing the importance of a consistent and comprehensive onboarding and safety training experience for new hires across our facility footprint, we have implemented a web-based training program to ensure every employee receives a consistent message from the start of their employment. The new program includes two videos detailing the Company and its primary business lines as well as a new hire folder filled with information on employee programs, services, benefits and more.

We have also implemented a toolkit to help managers guide new employees for success and we have begun to conduct regular new hire surveys to solicit feedback and identify opportunities for improvement. We continue to evaluate and employ methods to identify at-risk behaviors during the hiring process to place prospective employees in appropriately suited positions where they can be successful and workplace injuries can be avoided. This behavioral data also enables us to tailor training and onboarding based on the opportunities it highlights.

Performance Management

To ensure our employees have the best opportunity for success, our performance development process includes periodic meetings between employees and managers to discuss their goals and strategies to achieve them. We no longer conduct traditional annual reviews and instead opt for these more frequent two-way discussions focused on fostering ideas that will enable employee success. Each manager is expected to meet one-on-one at least monthly with their employees to discuss tailored strategies to encourage employee success like additional training, attendance at conferences or establishing connections to others within our company. These monthly meetings also help managers gauge employee engagement and develop approaches to increase and sustain positive engagement.

We have also implemented a New Hire Mentoring Program as another component of our development process. The program provides both hourly and salaried employees an extra opportunity to receive support from experienced employees and discuss any ideas they may have for improving our operations or their work experience. Prior to participating, mentors and mentees receive training on getting the most out of the program and surveys are conducted throughout to measure success.

Training and Education

As a part of our people-focused approach to our operations, we are committed to helping our employees thrive in their roles and grow both personally and professionally. A major component of this prerogative is our commitment to providing each employee with the training and education they need to be successful. We foster innovation and develop our next wave of high-potential employees through our leadership forum, an intensive nine-month program conducted in partnership with a university local to our corporate headquarters. Approximately ten to twelve employees from across the world are chosen annually for each cohort. Selected participants travel to our corporate headquarters to take part in workshops facilitated by university professors and business leaders. We also offer our employees a tuition reimbursement program to help them pursue degrees and certifications related to relevant skills they utilize for their positions to further personal and company success.

Inclusion and Diversity

We support an inclusive and diverse work environment across our company through a range of strategic programs. Our internal processes and programs target inclusion and diversity as a key area of importance and externally we place emphasis on the topic during philanthropic activities. Our Director for Global Inclusion and Diversity focuses on supporting our strategy to be an employer of choice, chairs the company's Inclusion and Diversity Committee, and helps to ensure that all employees feel they are heard and valued to harness the power of an engaged workforce.

Compensation and Benefits

We encourage employee participation in our benefit programs for saving for retirement through robust defined contribution and employee stock purchase programs. The U.S. 401(k) program includes both traditional matching and an additional non-elective company contribution based on organizational performance. When the company achieves the established performance target, employees share in this success through an automatic contribution to their 401(K) accounts. We also offer our employees the option to acquire Koppers stock through an employee stock purchase program. The program gives our employees the opportunity to buy shares at a discount through payroll deductions during defined quarterly offering periods.


Koppers Holdings Inc.     2020 Annual Report


Health and Safety

We believe a robust wellness program that encourages employee participation is key to promoting healthy lifestyles and decision-making. Our wellness screening program for our U.S.-based employees provides employees the opportunity to learn more about their health and daily routines. As part of this program, employees can earn financial incentives for completing a variety of wellness initiatives. Recognizing the importance of supporting our employees in all aspects of their lives, we provide an Employee Assistance Program with a full range of supportive resources including financial wellness, mental health and family services. For our U.S.-based employees, we also offer four weeks of paid time-off for mothers and fathers who have a birth or adoption as part of our parental bonding leave program. Additionally, we offer flexible work schedules around core hours.

Environmental, Social and Governance Matters

Corporate social responsibility, our obligation to people, the environment, and to good corporate governance processes, has been a part of our culture for many years. We believe this culture, supported by a spirit of collaboration and innovation, allows us to decrease our impact on the environment and create value for all of our stakeholders. We published our first Corporate Social Responsibility report (CSR) in 2008 and our historical CSR reports are available on The contents of our corporate website are not incorporated by reference in this Annual Report on Form 10-K or in any other report or document we file with the Securities and Exchange Commission.

We have established a governance structure to support and develop our sustainability practices. In 2020, we established a Sustainability Committee of the board of directors to provide oversight of our programs. Management provides direction through its Leadership Council, chaired by the CEO. Our Sustainability Steering Committee provides guidance on goals and programs designed to improve our performance against those expectations. Toward this goal and starting in 2019, we began work on a materiality analysis, both internal and external, that highlighted the areas where we can most effectively address the needs of our stakeholders.


The circular nature of our business starts with our raw materials, the majority volume of which are by-products generated by other industries (including scrap copper and coal tar) and renewable resources (trees). We purchase approximately 33 million pounds of scrap copper which is postconsumer or post-industrial in nature. We believe this places Koppers in the center of what is known as the “circular economy” that emphasizes the “reduce, reuse, recycle” mentality that continues to frame global conservation efforts. Our wood-treatment solutions, while supporting an important role in our global infrastructure across multiple industries, also support an important role in the carbon cycle. Treating wood significantly increases its useful lifespan, allowing the carbon stored within the wood to be immobilized for up to 50 years, keeping it out of the atmosphere and limiting carbon’s impact on the environment. In addition, we have businesses which have product life cycle management capabilities to help solve our customers’ challenge of responsibly disposing of end-of-life crossties and utility poles by repurposing used wood products, including as a fuel source. This reduces the end-of-life impact of our ties and poles, contributing to greater product sustainability.


We are committed to proactively evaluating and addressing community needs in the areas where we operate. Many of our locations have made strong connections with local community members, allowing Koppers representatives to share facility information and address any questions, observations, concerns and ideas. Our community impact is demonstrated through our employees’ volunteer commitments and a corporate philanthropy program. Employees worldwide volunteer their time to mentor students, enhance local education initiatives, take care of the elderly, assist at homeless shelters and provide hands-on help to those affected by natural disasters.  

We believe our ability to positively impact our communities and environment starts with investing in our employees. Our people-focused strategy considers all aspects of the employee experience, from hiring practices and onboarding to health and wellness and talent management.


Collaboration – Communication across our global footprint drives our efforts. All Koppers employees take part in safety training programs and provide direct feedback to leadership as part of the company’s annual engagement survey.


Inclusion and Diversity – We are committed to supporting inclusion and diversity in process and practice. Our Culture and Engagement team ensures that a diverse slate of candidates is considered for open positions. Our first employee resource group, LINKWomen, which was launched in 2018, provides an important development forum for employees and serves as a model for future initiatives. Additionally, the composition of our board of directors has been recognized for gender and racial diversity.




We believe our corporate governance structure is designed to assure accountability to our stakeholders and to make certain that we conduct business in a responsible, ethical way. We maintain a comprehensive Code of Conduct that details the expectations and requirements we have as an organization for our employees. This Code of Conduct applies to all employees, whether we are engaging in peer-to-peer interactions, working to comply with complex regulations, marketing our products, purchasing materials, creating new products, managing our finances or interacting with our communities.

Our board of directors is broadly responsible for contributing to the strategic direction and oversight of the company. There are five board committees, including: Audit; Nominating and Corporate Governance; Management Development and Compensation; Strategy and Risk; and Sustainability. Among its duties and responsibilities, the Board oversees management’s direction of the legal, ethical and socially responsible behavior of the company, such as developing effective performance measurement systems, reviewing the company's long-term strategy and overseeing risk management processes.

Our Leadership Council is responsible for directing the development and implementation of the company's strategic plan, and business operations around the globe. These executive leaders establish and maintain our commitment to ethics, integrity, fiscal responsibility, growth and sustainability.

You should carefully consider the risks described below before investing in our publicly traded securities. Our business is subject to the risks that affect many other companies, such as competition, technological obsolescence, labor relations, general economic conditions, geopolitical events and international operations.

Risks Related to Our Business

Fluctuations in the price, quality and availability of our primary raw materials could reduce our profitability.

Our operations depend on an adequate supply of quality raw materials being available on a timely basis. The loss of a key source of supply or a delay in shipments could cause a significant increase in our operating expenses. For example, our operations are highly dependent on a relatively small number of freight transportation services. We are also dependent on specialized ocean-going transport vessels that we lease to deliver raw materials to our facilities and finished goods to our customers. Interruptions in such freight services could impair our ability to receive raw materials and ship finished products in a timely manner. We are also exposed to price and quality risks associated with raw material purchases. Such risks include the following:


The availability and cost of lumber are critical elements in our production of railroad crossties and pole products for our RUPS business. Historically, the supply and cost of hardwood for railroad crossties have been subject to availability and price pressures. We may not be able to obtain wood raw materials at economical prices in the future.


The availability of scrap copper is a critical element in our production of copper-based wood preservation chemicals for our PC business. Our purchase price for scrap copper is based upon spot prices in the copper market, which may be subject to sudden price changes. We may not be able to obtain scrap copper at prices that match underlying pricing commitments to our customers.


Pentachlorophenol has a significant market share for the treatment of utility poles in the United States and is a treatment preservative, in addition to chromated copper arsenate and creosote, that we use to treat utility poles. The only North American manufacturer of pentachlorophenol has announced that it will cease production by the end of 2021. Over the next 10 months, end-users of treated utility poles who require the use of pentachlorophenol-treated utility poles will have to adopt other available treatment systems for their electrical transmission and distribution networks. We may lose market share if our customers select a treatment system that we do not offer.


The primary raw material used by our CMC business is coal tar, a by-product of furnace coke production. Currently, our CMC business supplies our North American RUPS business with 100 percent of its creosote requirements. A shortage in the supply of domestic coal tar or a reduction in the quality of coal tar could require us to increase coal tar or creosote imports to meet future creosote demand. This could cause a significant increase in our operating expenses and we may be unable to pass some or all of these costs on to our customers.


Koppers Holdings Inc.     2020 Annual Report


In certain circumstances coal tar may also be used as an alternative to fuel. In the past, increases in energy prices have resulted in higher coal tar costs which we have attempted to pass through to our customers. If these increased costs cannot be passed through to our customers, it could result in margin reductions for our coal tar-based products.


Our price realizations and profit margins for phthalic anhydride have historically fluctuated with the price of orthoxylene and its relationship with phthalic anhydride; however, during periods of excess supplies of phthalic anhydride, margins may be reduced despite high levels for orthoxylene prices.


Our price realizations and profit margins for phthalic anhydride, naphthalene and carbon black feedstock have historically fluctuated with the market price of crude oil, market prices for chemicals derived from crude oil, such as orthoxylene, or market indices derived from crude oil.


We import certain raw materials that are used in our products that are, or may become, subject to tariffs and trade restrictions.

If the costs of raw materials increase significantly and we are unable to offset the increased costs with higher selling prices, our profitability will decline.

We face risks related to our substantial indebtedness.

As of December 31, 2020, we had total outstanding debt of $784.2 million, and approximately $307.8 million of additional unused borrowing capacity under our $600.0 million senior secured revolving credit facility and $100.0 million secured term loan facility (collectively, the “Credit Facility”). Our substantial leverage could adversely affect our ability to raise additional capital to fund our operations, limit our ability to react to changes in the economy or our industry, expose us to interest rate risk associated with our variable rate debt and prevent us from meeting our obligations under the Senior Notes due 2025 (the “2025 Notes”) and the Credit Facility as described in Note 15 of the Notes to Consolidated Financial Statements. A high level of indebtedness could have adverse consequences to us, including:


making it more difficult for us to make payments on our debt;


increasing our vulnerability to general economic and industry conditions;


requiring a substantial portion of cash flow from operations to be dedicated to the payment of principal and interest on our debt, thereby reducing our ability to use our cash flow to fund our operations, capital expenditures, and future business opportunities;


exposing us to the risk of increased interest rates as certain of our borrowings under our Credit Facility are at variable rates;


restricting us from making strategic acquisitions or causing us to make non-strategic divestitures;


limiting our ability to obtain additional financing for working capital, capital expenditures, product development, debt service requirements, acquisitions, and general corporate or other purposes; and


limiting our ability to adjust to changing market conditions and placing us at a competitive disadvantage compared to our competitors who may be less highly leveraged.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future, subject to the restrictions contained in our Credit Facility and the indenture governing the 2025 Notes. If new indebtedness is added to our current debt levels, the related risks that we now face could intensify.

Our debt agreements contain restrictions that limit our flexibility in operating our business.

Our Credit Facility and the indenture governing the 2025 Notes contain various covenants that limit our ability to engage in specified types of transactions. These covenants limit our ability and the ability of our restricted subsidiaries to, among other things:


incur additional debt;


pay dividends or distributions on our capital stock or repurchase our capital stock;


issue stock of subsidiaries;


make certain investments;


create liens on our assets to secure debt;


enter into transactions with affiliates;


merge or consolidate with another company; and


sell or otherwise transfer assets.



In addition, under the Credit Facility, we are required to meet specified financial ratios in order to undertake certain actions, and we are required to maintain a specified minimum fixed charge coverage ratio, a maximum total secured leverage ratio and a maximum total leverage ratio. Our ability to meet those tests can be affected by events beyond our control, and we cannot assure you that we will meet them. A breach of any of these covenants could result in a default under our Credit Facility. Upon the occurrence of an event of default under our Credit Facility, the lenders could elect to declare all amounts outstanding under our Credit Facility to be immediately due and payable and terminate all commitments to extend further credit. Such a declaration by the lenders under our Credit Facility would also constitute an event of default under our 2025 Notes. Similarly, a default under our 2025 Notes could also constitute an event of default under our Credit Facility.

If we were unable to repay those amounts, the lenders under our Credit Facility could proceed against the collateral granted to them to secure such indebtedness. We have pledged substantially all of our assets as collateral under our Credit Facility. If the lenders under our Credit Facility accelerate the repayment of borrowings, we cannot assure you that we will have sufficient assets to repay our Credit Facility, as well as our unsecured indebtedness, including notes.

We may not be able to generate sufficient cash to service all of our indebtedness, including the 2025 Notes, and may be forced to take other actions to satisfy our obligations under our indebtedness, which may not be successful.

Our ability to make scheduled payments on or to refinance our debt obligations depends on our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control. We cannot assure you that we will maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness, including the 2025 Notes.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay investments and capital expenditures, to sell assets, to seek additional capital, or to restructure or refinance our indebtedness, including the 2025 Notes. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations. In the absence of such operating results and resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations. Our Credit Facility restricts our ability to dispose of assets and use the proceeds from the disposition. We may not be able to consummate those dispositions or to obtain the proceeds that we could realize from them and these proceeds may not be adequate to meet any debt service obligations then due.

The interest rate of our Credit Facility is priced using a spread over LIBOR.

LIBOR, the London interbank offered rate, is the basic rate of interest used in lending between banks on the London interbank market and is widely used as a reference for setting the interest rate on loans globally. We use LIBOR as a reference rate in our Credit Facility such that the interest due to our creditors pursuant to our Credit Facility is calculated using LIBOR and our Credit Facility contains a stated minimum value for LIBOR. On July 27, 2017, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR, announced that it intends to phase out LIBOR. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, is focused on replacing U.S. dollar LIBOR with a new index calculated by short-term repurchase agreements, backed by Treasury securities – Secured Overnight Financing Rate (“SOFR”). SOFR is observed and backward looking, which stands in contrast with LIBOR under the current methodology, which is an estimated forward-looking rate and relies, to some degree, on the expert judgment of submitting panel members.

Given that SOFR is a secured rate backed by government securities, it will be a rate that does not take into account bank credit risk (as is the case with LIBOR). SOFR is therefore likely to be lower than LIBOR and is less likely to correlate with the funding costs of financial institutions. Whether or not SOFR attains market traction as a LIBOR replacement tool remains in question. As such, the future of LIBOR at this time is uncertain, however it is expected that LIBOR will be phased out before the end of 2023. If LIBOR ceases to exist, we will renegotiate our credit agreements that utilize LIBOR as a factor in determining the interest rate to replace LIBOR with the new standard that is established.

Demand for our products is cyclical and we may experience prolonged depressed market conditions for our products.

Our products are sold primarily into markets which historically have been cyclical, such as wood preservation, aluminum and specialty chemicals.


The principal use of our wood preservation chemicals is in the manufacture of treated lumber, which is used mainly for residential applications, such as wood decking, and also industrial applications, such as the treating of railroad crossties and utility poles. Therefore, a decline in remodeling and construction could reduce demand for wood preservation chemicals for residential applications and a decline in the capital spending requirements for railroads and utility companies could reduce demand for wood preservation chemicals for industrial applications.


Koppers Holdings Inc.     2020 Annual Report


The principal consumers of our carbon pitch are primary aluminum smelters. Although the global aluminum industry has experienced growth on a long-term basis, the aluminum industry has experienced a shift in primary aluminum production from the mature geographies, where we have historically enjoyed high market shares, to emerging economies.


The principal use of our phthalic anhydride product is in the manufacture of plasticizers and flexible vinyl, which are used mainly in the housing and automobile industries. Therefore, a decline in remodeling and construction or global automobile production could reduce the demand for phthalic anhydride.

We are dependent on major customers for a significant portion of our net sales, and the loss of one or more of our major customers could result in a significant reduction in our profitability as a whole or the profitability of a particular product.

Although no one customer accounted for more than eight percent of our net sales for the year ended December 31, 2020, our top ten customers accounted for approximately 39 percent of our net sales. The loss of a significant customer could have a material adverse effect on our business, cash flow and financial condition.

The development of new technologies or changes in our customers’ products could reduce the demand for our products.

Our products are used for a variety of applications by our customers. Changes in our customers’ products or processes may enable our customers to reduce consumption of the products we produce or make our products unnecessary. Customers may also find alternative materials or processes that no longer require our products.

As a producer of wood preservatives, we may incur additional costs under our warranties or otherwise for claims related to treated-wood products.

We provide limited warranties on certain treated-wood products. These limited warranties cover treated-wood products that are produced by certain of our customers who use wood preservatives supplied by us. The limited warranties generally provide for replacement of properly treated-wood (treated-wood only) or refund of the purchase price for the treated-wood product that prematurely fails due to fungal decay or termite attack. From time to time, we (or our customers) receive claims under these warranties or other claims relating to alleged failures of treated-wood products. Our profitability could be adversely affected if the amount of warranty claims against us or our customers significantly increase.

Hazards associated with chemical manufacturing may cause suspensions or interruptions of our operations.

Due to the nature of our business, we are exposed to the hazards associated with chemical manufacturing and the related use, storage and transportation of raw materials, products and wastes in our manufacturing facilities and our distribution centers, such as fires, explosions and accidents that could lead to a suspension or interruption of operations. Any disruption could reduce the productivity and profitability of a particular manufacturing facility or of our company as a whole. Other hazards include the following:


piping and storage tank leaks and ruptures;


mechanical failure;


exposure to hazardous substances; and


chemical spills and other discharges or releases of toxic or hazardous wastes, substances or gases.

These hazards, among others, may cause personal injury and loss of life, damage to property and contamination of the environment, which could lead to government fines or work stoppage injunctions, cleanup costs and lawsuits by injured persons. While we are unable to predict the outcome of such matters, if determined adversely to us, we may not have adequate insurance to cover related costs or liabilities and, if not, we may not have sufficient cash flow to pay for such costs or liabilities. Such outcomes could harm our customer goodwill and reduce our profitability and could have a material adverse effect on our business, financial condition, cash flow and results from operations.

We are subject to extensive environmental laws and regulations and may incur significant costs as a result of continued compliance with, violations of or liabilities under environmental laws and regulations.

Like other companies involved in environmentally sensitive businesses, our operations and properties are subject to extensive federal, state, local and foreign environmental laws and regulations, including those concerning the following, among other things:


the treatment, storage and disposal of wastes;


the investigation and remediation of contaminated soil and groundwater;


the discharge of effluents into waterways;




the emission of substances into the air;


the marketing, sale, use and registration of our chemical products, such as creosote, chromated copper arsenate and MicroPro®;


the U.S. Environmental Protection Agency’s regulation under the Federal Insecticide, Fungicide, and Rodenticide Act which requires the registration and authorization of antimicrobial pesticide products to be used for various applications in the United States;


the Health Canada Pest Management Regulatory Agency and its Pest Control Products Act which requires the registration and authorization of antimicrobial pesticide products to be used for various applications in Canada;


the European Union’s regulation under the Registration Evaluation Authorization and Restriction of Chemicals, which requires manufacturers or importers of substances manufactured or imported into the European Union in quantities of one ton per year or more to register with a central European Chemicals Agency;


the European Union’s regulation under the Biocidal Products Regulation, which requires a biocidal product to be authorized by the European Chemicals Agency before it can be marketed or used in the European Union;


the Great Britain Biocidal Products Regulation, which requires a biocidal product to be authorized before it can be marketed or used in Great Britain; and


other matters relating to environmental protection and various health and safety matters.

We have incurred, and expect to continue to incur, significant costs to comply with environmental laws and regulations as a result of remedial obligations. We could incur significant costs, including cleanup costs, fines, civil and criminal sanctions and claims by third parties for property damage and personal injury, as a result of violations of or liabilities under environmental laws and regulations. We accrue for environmental liabilities when a determination can be made that they are probable and reasonably estimable. Total environmental reserves at December 31, 2020 were $11.0 million, which include provisions primarily for environmental remediation. In addition, we incur significant annual operating expenses related to environmental matters and significant capital expenditures related to environmental control facilities. Capital expenditures related to environmental control facilities in 2021 are expected to total approximately $30 million and are expected to be funded by operations.

Contamination has been identified and is being investigated and remediated at many of our sites by us or other parties. We believe that we will have continuing significant expenditures associated with compliance with environmental laws and regulations and, to the extent not covered by insurance or available recoveries under third-party indemnification arrangements, for present and future remediation efforts at plant sites and third-party waste sites and other liabilities associated with environmental matters. There can be no assurance that these expenditures will not exceed current estimates and will not have a material adverse effect on our business, financial condition, cash flow and results of operations.

Actual costs and liabilities to us may exceed forecasted amounts. Moreover, currently unknown environmental issues, such as the discovery of additional contamination or the imposition of additional sampling or cleanup obligations with respect to our sites or third-party sites, may result in significant additional costs, and potentially significant expenditures could be required in order to comply with future changes to environmental laws and regulations or the interpretation or enforcement thereof. We also are involved in various litigation and proceedings relating to environmental matters and toxic tort claims.

Future climate change regulation could result in increased operating costs and reduced demand for our products.

Increasing societal concerns about climate change have resulted in international efforts to limit greenhouse gas (GHG) emissions. International climate change-related efforts, such as the Paris Agreement, may impact the regulatory framework of countries whose policies and laws directly influence our operations. Currently, in the United States, various federal, state and regional legislative and regulatory measures to address greenhouse gas are in phases of consideration, promulgation or implementation. These include actions which could require reductions in our greenhouse gas emissions or establish a carbon tax.


Koppers Holdings Inc.     2020 Annual Report


Heavy energy-using installations in the European Union operate under the EU Emissions Trading System (EU ETS), a cap and trade system on emissions. Under this System, organizations apply to the Member State for an allowance of GHG emissions. These allowances are gradually reduced year by year, to encourage reductions and are also tradable to enable companies that reduce their GHG emissions to sell their excess allowances to companies that are not reaching their emissions objectives. The Green Deal, which was approved by the EU Parliament in 2020, has set a goal of a 55 percent reduction in emissions by 2030 and carbon neutrality by 2050. This will include revising and possibly expanding the EU ETS and setting targets for sectors outside the EU ETS. In Australia, the National Greenhouse and Energy Reporting Scheme requires large volume emitters to report carbon emissions and energy use to the government annually and, based on certain thresholds, purchase certificates to authorize additional emissions. Although Koppers does not currently exceed that threshold, it is foreseeable that the government could lower the threshold in the future.

Any laws or regulations that are adopted to reduce emissions of GHGs could (i) cause an increase to our raw material costs, (ii) increase our costs to operate and maintain our facilities, (iii) increase costs to administer and manage emissions programs, and (iv) have an adverse effect on demand for our products.

The insurance that we maintain may not fully cover all potential exposures.

We maintain property, casualty, general liability, workers’ compensation, pollution legal liability and other insurance, but such insurance may not cover all risks associated with the hazards of our business and is subject to limitations, including deductibles and maximum limits. We may incur losses beyond the limits, or outside the coverage, of our insurance policies, including liabilities for environmental compliance and remediation. In addition, from time to time, various types of insurance for companies in our industry have not been available on commercially acceptable terms or, in some cases, have not been available at all. In the future, we may not be able to obtain coverage at current levels, and our premiums may increase significantly on coverage that we maintain.

Adverse weather conditions or natural disasters may reduce our operating results.

Our quarterly operating results fluctuate due to a variety of factors that are outside our control, including inclement weather conditions, which in the past have caused a decline in our operating results. For example, adverse weather conditions have at times negatively impacted our supply chain as wet conditions impacted logging operations, reducing our ability to procure crossties. In addition, adverse weather conditions have had a negative impact on our customers in our pavement sealer and wood preservation businesses, resulting in a negative impact on our sales of these products. Moreover, demand for many of our products declines during periods of inclement weather. Finally, natural disasters, including wildfires, hurricanes and earthquakes could affect our revenue and operating results. It is impossible to predict the timing, magnitude or location of such natural disasters or their impacts on the local economy and on our operations. If a major wildfire, hurricane or other natural disaster were to disrupt the supply of our raw materials or damage or destroy our facilities or manufacturing equipment, we may experience potential impacts ranging from production and shipping delays to lost profits and revenues.

Beazer East and Beazer Limited may not continue to meet their obligations to indemnify us.

Under the terms of the asset purchase agreement between us and Koppers Company, Inc. (now known as Beazer East, Inc.) upon the formation of Koppers Inc. in 1988, subject to certain limitations, Beazer East and Beazer Limited assumed the liability for and indemnified us against, among other things, certain clean-up liabilities for contamination occurring prior to the purchase date at sites acquired from Beazer East and certain third-party claims arising from such contamination (the “Indemnity”). Beazer East and Beazer Limited (which are indirect subsidiaries of Heidelberg Cement AG) may not continue to meet their obligations. Beazer East could in the future choose to challenge its obligations under the Indemnity or our satisfaction of the conditions to indemnification imposed on us thereunder. The government and other third parties may have the right under applicable environmental laws to seek relief directly from us for any and all such costs and liabilities.

In July 2004, we entered into an agreement with Beazer East to amend the December 29, 1988 asset purchase agreement to provide, among other things, for the continued tender of pre-closing environmental liabilities to Beazer East under the Indemnity through July 2019. To the extent that such third-party claims were not tendered by July 2019, Beazer East is not required to pay the costs arising from such claims under the Indemnity and furthermore, Beazer East may now tender certain of such claims to Koppers Inc. However, with respect to any such claims which were made by July 2019, Beazer East will continue to be responsible for such claims under the Indemnity beyond July 2019. The July 2004 amendment did not change the provisions of the Indemnity with respect to indemnification for non-environmental claims, such as product liability claims, which claims may continue to be asserted after July 2019. Qualified expenditures under the Indemnity are not subject to a monetary limit.



The Indemnity provides for the resolution of issues between Koppers Inc. and Beazer East by an arbitrator on an expedited basis upon the request of either party. The arbitrator could be asked, among other things, to make a determination regarding the allocation of environmental responsibilities between Koppers Inc. and Beazer East. Arbitration decisions under the Indemnity are final and binding on the parties.

Without Beazer continuing to assume the financial responsibility under the Indemnity, the obligation to pay the costs and assume the liabilities relating to these matters would have a significant impact on our net income. Furthermore, we could be required to record a contingent liability on our balance sheet with respect to environmental matters covered by the Indemnity, which could result in our having significant negative net worth. Finally, the Indemnity does not afford us indemnification against environmental costs and liabilities attributable to acts or omissions occurring after the closing of the acquisition of assets from Beazer East under the asset purchase agreement, nor is the Indemnity applicable to liabilities arising in connection with other acquisitions by us after that closing.

Litigation against us could be costly and time-consuming to defend, and due to the nature of our business and products, we may be liable for damages arising out of our acts or omissions, which may have a material adverse effect on us.

We are and have been a defendant in a significant number of lawsuits in which the plaintiffs claim they have suffered a variety of illnesses (including cancer) and/or property damage as a result of exposure to coal tar pitch, pavement sealer, benzene, wood treatment chemicals and other chemicals. In addition, we are regularly subject to legal proceedings and claims that arise in the ordinary course of business, such as workers’ compensation claims, governmental investigations, employment disputes, and customer and supplier disputes arising out of the conduct of our business. We also are involved in various litigation and proceedings relating to environmental matters. Any litigation or regulatory enforcement action that may arise could result in substantial costs and may divert management’s attention and resources away from the day-to-day operation of our business.

We are indemnified for certain product liability exposures under the Indemnity with Beazer East related to products sold prior to the closing of the acquisition of assets from Beazer East. Beazer East and Beazer Limited may not continue to meet their indemnification obligations. In addition, Beazer East could choose to challenge its indemnification obligations or our satisfaction of the conditions to indemnification imposed on us thereunder. If for any reason (including disputed coverage or financial incapability) one or more of such parties fail to perform their obligations and we are held liable for or otherwise required to pay all or part of such liabilities without reimbursement, the imposition of such liabilities on us could have a material adverse effect on our business, financial condition, cash flows and results of operations. Furthermore, we could be required to record a contingent liability on our balance sheet with respect to such matters, which could result in us having significant negative net worth.

Intellectual property rights are important to our business. If our patents are declared invalid or our trade secrets become known to our competitors, our ability to compete may be adversely affected.

Proprietary protection of our processes, apparatuses and other technology is important to our business, particularly in our PC business. Consequently, we may have to rely on judicial enforcement of our patents and other proprietary rights, which is generally a time consuming and expensive process. While a presumption of validity exists with respect to patents issued to us in the United States, there can be no assurance that any of our patents will not be challenged, invalidated, circumvented or rendered unenforceable. Furthermore, if any pending patent application filed by us does not result in an issued patent, or if patents are issued to us, but such patents do not provide meaningful protection of our intellectual property, or if patents issued to us expire, then our ability to compete may be adversely affected. Additionally, our competitors or other third parties may obtain patents that restrict or preclude our ability to lawfully produce or sell our products in a competitive manner, which could have a material adverse effect on our business, cash flow and financial condition. The growth of our business also depends on our ability to develop new intellectual property rights, including patents, and the successful implementation of innovation initiatives. There can be no assurance that our efforts to do so will be successful and the failure to do so could negatively impact our results of operations.

We also rely upon unpatented proprietary know-how and continuing technological innovation and other trade secrets to develop and maintain our competitive position, particularly in our PC business. While it is our practice to enter into confidentiality agreements with our employees and third parties to protect our intellectual property, these confidentiality agreements may be breached or may not provide meaningful protection for our trade secrets or proprietary know-how, and adequate remedies may not be available in the event of an unauthorized use or disclosure of our trade secrets and know-how. In addition, others could obtain knowledge of our trade secrets through independent development or other access by legal means. The failure of our patents or confidentiality agreements to protect our processes, apparatuses, technology, trade secrets or proprietary know-how could have a material adverse effect on our business, cash flow and financial condition.


Koppers Holdings Inc.     2020 Annual Report


We may be required to recognize impairment charges for our long-lived assets.

At December 31, 2020, the net carrying value of long-lived assets (property, plant and equipment, operating lease right-of-use assets, goodwill and other intangible assets) totaled $959.2 million. In accordance with generally accepted accounting principles, we periodically assess these assets to determine if they are impaired. Significant negative industry or economic trends, disruptions to our business, unexpected significant changes or planned changes in use of the assets, divestitures and market capitalization declines may result in impairments to goodwill and other long-lived assets. Future impairment charges could significantly affect our results of operations in the periods recognized. Impairment charges would also reduce our shareholders’ equity and could affect compliance with the covenants in our debt agreements.

We are subject to risks inherent in foreign operations, including additional legal regulation, and changes in social, political and economic conditions.

We have operations in the United States, Australia, Denmark, the United Kingdom, New Zealand and Canada, among others, and sell our products in many foreign countries. For the year ended December 31, 2020, net sales from products sold by our foreign subsidiaries accounted for approximately 25 percent of our total net sales.

Doing business on a global basis requires us to comply with the laws and regulations of the U.S. government and various international jurisdictions. These regulations place restrictions on our operations, trade practices and partners and investment decisions. In particular, our international operations are subject to U.S. and foreign anti-corruption laws and regulations, such as the Foreign Corrupt Practices Act, and economic sanction programs administered by the U.S. Treasury Department’s Office of Foreign Assets Control. Violations of these laws and regulations may result in civil or criminal penalties, including fines. Our United Kingdom operations may be affected by the United Kingdom’s departure from the European Union, known as Brexit. For example, Brexit could lead to legal uncertainty and potentially divergent national laws and regulations as the United Kingdom determines which European Union laws to replace or replicate.

For example, some of our operations are subject to the European Union’s General Data Protection Regulation (“GDPR”), which became effective in May 2018. The GDPR creates a range of new compliance obligations for companies that process personal data of European Union residents and increases financial penalties for non-compliance. We process personal data of our employees who are European Union residents and will continue dedicating financial resources and management time to GDPR compliance. We bear the cost of compliance with the GDPR and are subject to fines and penalties in the event of a breach of the GDPR, which could have an adverse impact on our business, financial condition or results of operations.

Political and financial instability can lead to economic uncertainty and may adversely impact our business. In addition, as a global business, we are also exposed to market risks relating to fluctuations in interest rates and foreign currency exchange rates. Our international revenues could be reduced by currency fluctuations or devaluations. Changes in currency exchange rates could lower our reported revenues and could require us to reduce our prices to remain competitive in foreign markets, which could also reduce our profitability. We are also subject to potentially increasing transportation and shipping costs associated with international operations. Furthermore, we are also exposed to risks associated with changes in the laws and policies governing foreign investments in countries where we have operations as well as changes in U.S. laws and regulations relating to foreign trade and investment.

Labor disputes could disrupt our operations and divert the attention of our management and may cause a decline in our production and a reduction in our profitability.

Many of our employees are represented by a number of different labor unions and are covered under numerous labor agreements. Typically, a number of our labor agreements are scheduled to expire each year. We may not be able to reach new agreements without union action or on terms satisfactory to us. Any future labor disputes with any such unions could result in strikes or other labor protests, which could disrupt our operations and divert the attention of our management from operating our business. If we were to experience a strike or work stoppage, it may be difficult for us to find a sufficient number of employees with the necessary skills to replace these employees. Any such labor disputes could cause a decline in our production and a reduction in our profitability.

Our post-retirement obligations are currently underfunded. We may be required to make significant cash payments to our pension and other post-retirement plans, which will reduce the cash available for our business.

As of December 31, 2020, our benefit obligation under our defined benefit pension plans exceeded the fair value of plan assets by $25.3 million. Our pension asset funding to total pension obligation ratio was 89 percent as of December 31, 2020. The underfunding was caused, in large part, by fluctuations in the financial markets that impacted the value of the assets in our defined benefit pension plans and by fluctuations in interest rates which increased the discounted pension liabilities. In addition, our obligations for other post-retirement benefit obligations are unfunded and total $10.5 million at December 31, 2020.


During the years ended December 31, 2020 and December 31, 2019, we contributed $4.3 million and $4.5 million, respectively, to our post-retirement benefit plans. Management expects that any future obligations under our post-retirement benefit plans that are not currently funded will be funded from our future cash flow from operations. If our contributions to our post-retirement benefit plans are insufficient to fund the post-retirement benefit plans adequately to cover our future obligations, the performance of the assets in our pension plans does not meet our expectations or other actuarial assumptions or mandatory funding laws are modified, our contributions to our post-retirement benefit plans could be materially higher than we expect, thus reducing the cash available for our business.

We may incur significant charges in the event we close all or part of a manufacturing plant or facility.

We periodically assess our manufacturing operations in order to manufacture and distribute our products in the most efficient manner. Based on our assessments, we may make capital improvements to modernize certain units, move manufacturing or distribution capabilities from one plant or facility to another plant or facility, discontinue manufacturing or distributing certain products or close all or part of a manufacturing plant or facility, any of which could cause us to incur significant charges. The actual costs to close a manufacturing facility may exceed our original cost estimate and may have a material adverse effect on our financial condition, cash flow from operations and results from operations.

We may be subject to information technology systems failures, network disruptions and breaches of data security, which could harm our relationships with our customers and third-party business partners, subject us to negative publicity and litigation and cause substantial harm to our business.

We depend on integrated information systems to conduct our business. Information technology systems failures could disrupt our operations by impeding our processing of transactions, our ability to protect customer or company information and our financial reporting. System failures include risks associated with upgrading our systems, integrating information technology and other systems in connection with the integration of businesses we acquire, network disruptions and breaches of data security. Our computer systems, including our back-up systems, could be damaged or interrupted by power outages, computer and telecommunications failures, computer viruses, internal or external security breaches, events such as fires, earthquakes, floods, tornadoes and hurricanes, and/or errors by our employees.

We have been subject to cyberattacks in the past, including phishing and malware incidents, and although no such attack has had a material adverse effect on our business, this may not be the case with future attacks. As the prevalence of cyberattacks continues to increase, our information technology systems may be subject to increased security threats and we may incur additional costs to upgrade and maintain our security measures in place to prevent and detect such threats. The security and privacy measures that our vendors and customers implement may not be sufficient to prevent and detect cyberattacks that could have a material adverse effect on our financial condition, results of operations and cash flows. While our vendor agreements typically contain provisions that seek to eliminate or limit our exposure to liability for damages from a cyberattack, we cannot assure that such provisions will withstand legal challenges or cover all or any such damages.

In addition, outside parties may attempt to fraudulently induce employees or customers to disclose access credentials or other sensitive information in order to gain access to our systems and networks. We also may be subject to additional vulnerabilities as we integrate the systems, computers, software and data of acquired businesses and third-party business partners into our networks and separate the systems, computers, software and data of disposed businesses from our networks.

There are no assurances that our security measures, our business continuity and disaster recovery plans or actions or our investments to improve the maturity of our systems, processes and risk management framework to remediate vulnerabilities will be sufficient or completed quickly enough to prevent or detect or limit the impact of critical adverse events such as cyberattacks or security breaches. Potential consequences include, but are not limited to, transactional errors, business disruptions, loss of or damage to intellectual property, loss of customers and business opportunities, unauthorized access to or disclosure of confidential or personal information, regulatory fines, penalties or litigation, reputational damage, reimbursement or other compensatory costs and additional compliance costs. Any of these could have a material adverse effect on our financial condition, results of operations and cash flows.



Koppers Holdings Inc.     2020 Annual Report


Health concerns arising from the outbreak of a health epidemic or pandemic, including the currently ongoing COVID-19 pandemic, may have an adverse effect on our business, operating results and financial condition.

The outbreak of COVID-19 is a global situation that is continually evolving. The COVID-19 pandemic is having a significant impact on global markets as a result of supply chain and production disruptions, workforce restrictions, reduced spending and other factors. Our operating results are subject to fluctuations based on general economic conditions, and the extent to which the COVID-19 pandemic ultimately may impact our business will depend on future developments, such as the efficacy of spread prevention measures and new vaccines, the duration of the outbreak and business closures or business disruptions for us, our suppliers and our customers, all of which are highly uncertain and cannot be predicted with confidence. These same uncertainties exist with respect to any other health epidemic or pandemic that may arise in the future.

Any resulting financial distress of our customers due to deterioration in economic conditions could result in reduced sales and decreased collectability of accounts receivable, which would negatively impact our results of operations. The COVID-19 pandemic or any other health epidemic or pandemic also could have a material impact on our ability to obtain the raw materials and parts that we need in order to manufacture our products as our suppliers face disruptions in their businesses or closures. If our suppliers fail to meet our manufacturing needs, it could delay our production and shipments to customers and negatively affect our operations.

U.S. and international governmental responses to the COVID-19 pandemic have included “shelter in place”, “stay at home” and similar types of orders. These orders exempt certain individuals and businesses needed to maintain continuity of operations of critical infrastructure sectors as determined by the federal government. Although most of our operations have been considered essential and exempt, and therefore have been able to continue to operate without interruption, our operations in certain jurisdictions have temporarily curtailed from time to time. If any of the applicable exemptions are amended or revoked in the future or if additional restrictions that impact us are implemented in response to COVID-19 or any other health epidemic or pandemic, it could adversely impact our business, operating results and financial condition. Furthermore, to the extent that any of these exemptions do not extend to our key suppliers and customers, this also would adversely impact us in turn.

In addition, our operations or the operations of our customers or suppliers could be disrupted if any of our or their employees were suspected of having contracted COVID-19 or any similar significant virus since such an occurrence could require us or our business partners to quarantine some number of employees, take actions to disinfect facilities or otherwise cause operations to be idled.

The ultimate impact of the current COVID-19 pandemic on general economic conditions, our business and our ability to generate cash flow and profits cannot be quantified given the uncertainties existing with respect to the extent and timing of the potential future spread or mitigation of COVID-19 and the imposition or relaxation of protective measures. To the extent the current COVID-19 pandemic or any other future health epidemic or pandemic adversely affects our business and financial results, it also may have the effect of increasing many of the other risks described herein.

Risks Related to Our Common Stock

We have not declared a dividend since November 2014.

We are not required to pay dividends, and our shareholders are not guaranteed, and do not have contractual rights, to receive dividends. Our board of directors may decide at any time, in its discretion, to change or revoke our dividend policy. We currently intend to use the annual cash savings from not paying a dividend to preserve financial flexibility while funding our strategic growth initiatives and debt repayments. Any determination to pay dividends in the future will be at the discretion of our board of directors and will depend upon results of operations, financial condition, contractual restrictions, restrictions imposed by applicable law and other factors our board of directors deems relevant.

The ability of Koppers Inc. and its subsidiaries to pay dividends or make other payments or distributions to us will depend on our operating results and may be restricted by, among other things, the covenants in Koppers Inc.’s Credit Facility. Our ability to pay dividends is also limited by the indenture governing the 2025 Notes as well as Pennsylvania law and may in the future be limited by the covenants of any future outstanding indebtedness we or our subsidiaries incur. If a dividend is paid in violation of Pennsylvania law, each director approving the dividend could be liable to the corporation if the director did not act with such care as a person of ordinary prudence would use under similar circumstances. Directors are entitled to rely in good faith on information provided by employees of the corporation and experts retained by the corporation. Directors who are held liable would be entitled to receive a contribution to any such liability from any shareholders who received an unlawful dividend knowing it to be unlawful. Furthermore, we are a holding company with no operations, and unless we receive dividends, distributions, advances, transfers of funds or other payments from our subsidiaries, we will be unable to pay dividends on our common stock.


Provisions of our charter documents may inhibit a takeover, which could negatively affect our stock price.

Provisions of our charter documents and the Business Corporation Law of Pennsylvania, the state in which we are incorporated, could discourage potential acquisition proposals or make it more difficult for a third party to acquire control of our company, even if doing so might be beneficial to our shareholders. Our Amended and Restated Articles of Incorporation (our “Articles of Incorporation”) and our Second Amended and Restated Bylaws (our “Bylaws”) provide for various procedural and other requirements that could make it more difficult for shareholders to effect certain corporate actions. For example, our Articles of Incorporation authorize our board of directors to determine the rights, preferences, privileges and restrictions of unissued series of preferred stock without any vote or action by our shareholders. Our board of directors can therefore authorize and issue shares of preferred stock with voting or conversion rights that could adversely affect the voting or other rights of holders of our common stock. The following additional provisions could make it more difficult for shareholders to effect certain corporate actions:


Our shareholders will be able to remove directors only for cause by the affirmative vote of the holders of a majority of the outstanding shares of our capital stock entitled to vote in the election of directors. Vacancies on our board of directors may be filled only by our board of directors.


Under Pennsylvania law, cumulative voting rights are available to the holders of our common stock if our Articles of Incorporation have not negated cumulative voting. Our Articles of Incorporation provide that our shareholders do not have the right to cumulative votes in the election of directors.


Our Articles of Incorporation do not permit shareholder action without a meeting by consent except for the unanimous consent of all holders of our common stock. The Articles of Incorporation also provide that special meetings of our shareholders may be called only by the board of directors or the chairman of the board of directors.


Our Bylaws provide that shareholders seeking to nominate candidates for election as directors or to bring business before an annual meeting of shareholders must provide timely notice of their proposal in writing to the corporate secretary.

These provisions may discourage acquisition proposals and may make it more difficult or expensive for a third party to acquire a majority of our outstanding voting stock or may delay, prevent or deter a merger, acquisition, tender offer or proxy contest, which may negatively affect our stock price.

General Risk Factors

Conditions in the global economy and global capital markets may adversely affect our results of operations, financial condition and cash flows.

In recent history, the U.S. and global economy and capital markets have experienced significant uncertainties and volatility. Our business and operating results can be significantly affected by global economic issues. Our customers may experience deterioration of their business during the adverse business cycles. They may experience cash flow shortages and may have difficulty obtaining financing. As a result, our customers may delay or cancel plans to purchase our products and may not be able to fulfill their payment obligations to us in a timely fashion. Our suppliers may be experiencing similar conditions which could impact their ability to supply us with raw materials and otherwise fulfill their obligations to us. If global economic conditions deteriorate significantly, there could be a material adverse effect to our results of operations, financial condition and cash flows.

In addition, we rely on our Credit Facility with a consortium of banks to provide us with liquidity to meet our working capital needs. Our ability to fund our liquidity needs and working capital requirements could be impacted in the event that disruptions in the credit markets result in the banks being unable to lend to us under our Credit Facility.

Global economic issues could prevent us from accurately forecasting demand for our products, which could have a material adverse effect on our results of operations and our financial condition.

Adverse global economic issues, market instability and volatile commodity price fluctuations make it increasingly difficult for us, our customers and our suppliers to accurately forecast future product demands and sales prices, which could cause us to procure raw materials in excess of end-product demand. This could cause a material increase to our inventory carrying costs and, in the event of falling market prices for our end products, result in significant charges to write-down inventory to market prices.

We may not be able to compete successfully in any or all of the industry segments in which we operate.

The markets in which we operate are highly competitive, and this competition could harm our business, results of operations, cash flow and financial condition. If we are unable to respond successfully to changing competitive conditions, the demand for our products could be affected. We believe that the most significant competitive factor for our products is selling price.


Koppers Holdings Inc.     2020 Annual Report

Our products may be rendered obsolete or less attractive by changes in regulatory, legislative or industry requirements.

Changes in regulatory, legislative or industry requirements may render certain of our products obsolete or less attractive. Our ability to anticipate changes in these requirements, especially changes in regulatory standards, will be a significant factor in our ability to remain competitive. We may not be able to comply in the future with new regulatory, legislative and/or industrial standards that may be necessary for us to remain competitive and certain of our products may, as a result, become obsolete or less attractive to our customers.

Changes in applicable tax regulations and resolutions of tax disputes could negatively affect our financial results.

We are subject to income tax laws and regulations in the United States and various foreign jurisdictions. Significant judgment is required in evaluating and estimating our provision and accruals for these taxes. Our income tax liabilities are dependent upon the location of earnings among these different jurisdictions. Our income tax provision and income tax liabilities could be adversely affected by the jurisdictional mix of earnings, changes in valuation of deferred tax assets and liabilities and changes in tax laws and regulations. In the ordinary course of our business, we are also subject to continuous examinations of our income tax returns by tax authorities. Although we believe our tax estimates are reasonable, the final results of any tax examination or related litigation could be materially different from our related historical income tax provisions and accruals. Adverse developments in an audit, examination or litigation related to previously filed tax returns, or in the relevant jurisdiction’s tax laws, regulations, administrative practices, principles and interpretations could have a material effect on our results of operations and cash flows in the period or periods for which that development occurs, as well as for prior and subsequent periods.

Our strategy to selectively pursue complementary acquisitions may present unforeseen integration obstacles or costs.

Our business strategy includes the potential acquisition of businesses and entering into joint ventures and other business combinations that we expect would complement and expand our existing products and the markets where we sell our products. We may not be able to successfully identify suitable acquisition or joint venture opportunities or complete any particular acquisition, combination, joint venture or other transaction on acceptable terms. We cannot predict the timing and success of our efforts to acquire any particular business. Also, efforts to acquire other businesses or the implementation of other elements of this business strategy may divert managerial resources away from our business operations. In addition, our ability to engage in strategic acquisitions may depend on our ability to raise substantial capital and we may not be able to raise the funds necessary to implement our acquisition strategy on terms satisfactory to us, if at all. Our failure to identify suitable acquisition or joint venture opportunities may restrict our ability to grow our business. In addition, we may not be able to successfully integrate businesses that we acquire in the future or have recently acquired, which could lead to increased operating costs, a failure to realize anticipated operating synergies, or both.

We depend on our senior management team and other key employees and the loss of these employees could adversely affect our business.

Our success is dependent on the management, experience and leadership skills of our senior management team and key employees. The loss of any of these individuals or an inability to attract, retain and maintain additional personnel with similar industry experience could prevent us from implementing our business strategy. We cannot assure you that we will be able to retain our existing senior management and key personnel or to attract additional qualified personnel when needed. Senior management or key personnel may retire from time to time, and our employment agreements with these individuals may expire from time to time.

Our stock price may be extremely volatile.

There has been significant volatility in the market price and trading volume of equity securities, which is unrelated to the financial performance of the companies issuing the securities. These types of broad market fluctuations may negatively affect the market price of our common stock.

Some specific factors that may have a significant effect on our common stock market price include the following:


actual or anticipated fluctuations in our operating results or future prospects;


the public’s reaction to our press releases, our other public announcements and our filings with the Securities and Exchange Commission;


strategic actions by us or our competitors, such as acquisitions or restructurings;


new laws or regulations or new interpretations of existing laws or regulations applicable to our business;


changes in accounting standards, policies, guidance, interpretations or principles;




adverse conditions in the financial markets or general economic conditions, including those resulting from war, incidents of terrorism and responses to such events;


sales of common stock by us, members of our management team or a significant shareholder;


changes in stock market analyst recommendations or earnings estimates regarding our common stock or other comparable companies; and


changes in our current dividend policy.

We cannot predict the extent to which investor interest in our company will continue to support an active trading market for our common stock on the New York Stock Exchange (the “NYSE”) or otherwise or how liquid that market will continue to be. If there does not continue to be an active trading market for our common stock, you may have difficulty selling any of our common stock that you buy.

If securities analysts or industry analysts publish negative research or reports, or do not publish reports about our business, our share price and trading volume could decline.

The trading market for our common stock is influenced by the research and reports that industry or securities analysts publish about us, our business and our industry.  If one or more analysts adversely change their recommendation regarding our shares or our competitors’ stock, our share price would likely decline.  If one or more analysts cease coverage of us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our share price or trading volume to decline.

Future sales, or the perception of future sales, of a substantial amount of our common stock may depress the price of the shares of our common stock.

Future sales, or the perception or the availability for sale in the public market, of substantial amounts of our common stock could adversely affect the prevailing market price of our common stock and could impair our ability to raise capital through future sales of equity securities at a time and price that we deem appropriate.

We may issue shares of our common stock, or other securities, from time to time as consideration for future acquisitions and investments. We may also issue shares of our common stock, or other securities, in connection with employee stock compensation programs, employee stock purchase programs and board of directors’ compensation. In addition, we may issue shares of our common stock or other securities in public or private offerings as part of our efforts to raise additional capital. In the event any such acquisition, investment, issuance under stock compensation programs or offering is significant, the number of shares of our common stock or the number or aggregate principal amount, as the case may be, of other securities that we may issue may in turn be significant. We may also grant registration rights covering those shares or other securities in connection with any such acquisitions and investments. Any additional capital raised through the sale of our equity securities may dilute your percentage ownership in us.

Our ability to raise capital in the future may be limited.

Our ability to raise capital in the future may be limited.  Our business and operations may consume resources faster than we anticipate.  In the future, we may need to raise additional funds through the issuance of new equity securities, debt or a combination of both.  Additional financing may not be available on favorable terms, or at all.  If adequate funds are not available on acceptable terms, we may be unable to fund our capital requirements.  If we issue new debt securities, the debt holders would have rights senior to common shareholders to make claims on our assets, and the terms of any debt could restrict our operations, including our ability to pay dividends on our common stock.  If we issue additional equity securities, existing shareholders will experience dilution, and the new equity securities could have rights senior to those of our common stock.  Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings.  Thus, our shareholders bear the risk of our future securities offerings diluting their interest and reducing the market price of our common stock.

Koppers Holdings Inc.     2020 Annual Report




Our shares of common stock are listed and traded on the NYSE under the symbol “KOP”.

The number of registered holders of Koppers common stock at January 29, 2021 was 135.

Dividend Policy

In 2006, our board of directors adopted a dividend policy that provided for quarterly dividends, payable at the discretion of our board of directors. Dividends will be considered if cash generated by our business is in excess of our expected cash needs. Our expected cash needs include operating expenses and working capital requirements, interest and principal payments on our indebtedness, capital expenditures, incremental costs associated with being a public company, acquisitions, taxes and certain other costs. On an annual basis we expect to pay dividends, if declared, with cash flow from operations, but, due to seasonal or other temporary fluctuations in cash flow, we may from time to time use temporary short-term borrowings to pay quarterly dividends.

We are not required to pay dividends, and our shareholders will not be guaranteed, or have contractual or other rights, to receive dividends. Nevertheless, our board of directors may decide, in its discretion, at any time, to otherwise modify or repeal the dividend policy. We have not declared a dividend since November 2014. Any future determination to declare and pay dividends will be made at the discretion of our board of directors, after taking into account our financial results, capital requirements and other factors it may deem relevant.

Because we are a holding company, substantially all the assets shown on our consolidated balance sheet are held by our subsidiaries. Accordingly, our earnings and cash flow and our ability to pay dividends are dependent upon the earnings and cash flows of our subsidiaries and the distribution or other payment of such earnings to us in the form of dividends. Our ability to pay dividends is restricted by limitations on the ability of our only direct subsidiary, Koppers Inc., to pay dividends, as a result of limitations imposed by the Credit Facility, the indenture governing the 2025 Notes and by Pennsylvania law. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources – Restrictions on Dividends to Koppers Holdings.”

Issuer Purchases of Equity Securities

No shares were repurchased in the three months ended December 31, 2020 under the current $75 million share repurchase program approved in November 2011. The approximate dollar value of common shares that may yet be purchased under this program is $24.8 million. The repurchase program has no expiration date.

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: Railroad and Utility Products and Services (“RUPS”), Performance Chemicals (“PC”) and Carbon Materials and Chemicals (“CMC”).

Through our RUPS business, we believe that we are the largest supplier of wood crossties to the Class I railroads in North America. Our other treated wood products include utility poles for the electric, telephone, and broadband utility industries in the United States and Australia and construction pilings in the U.S. We also provide rail joint bar products as well as various services to the railroad industry in North America.

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.

Our CMC business processes coal tar into a variety of products, including creosote, carbon pitch, carbon black feedstock, naphthalene and phthalic anhydride, which are intermediate materials necessary in the pressure treatment of wood, the production of aluminum, the production of carbon black, the production of high-strength concrete, and the production of plasticizers and specialty chemicals, respectively.


Trend Overview

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; (ii) raw material pricing and availability, in particular the cost and availability of hardwood lumber for railroad crossties and 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, phthalic anhydride, and naphthalene; (iv) competitive conditions in global carbon pitch markets; and (v) changes in foreign exchange rates.

Effects of COVID-19 on our operations

Our operating results may fluctuate due to a variety of factors that are outside of our control, including from the effects of the current pandemic. The COVID-19 outbreak began to have a global effect in the first quarter of 2020 and continues to have a significant impact on global markets driven by supply chain and production disruptions, workforce restrictions, reduced spending and other factors. During the COVID-19 pandemic, substantially all of our global businesses have continued to operate without disruption. In the U.S., Koppers was designated as an essential business, as determined by the Cybersecurity and Infrastructure Security Agency (CISA) within the Department of Homeland Security. As a result, we have been able to meet the demands of our customers in the various markets we serve by continuing to operate to transport critical goods, provide power and connectivity to homes and businesses, and keep our infrastructure running reliably.

Our focus during this period has been on the following key priorities:


Protecting the health and safety of employees, customers and supply chain partners through deployment of new safety measures, including frequent communication and guidance to all employees on effective hygiene and disinfection, social distancing, limiting access to facilities, remote work when possible and use of face masks.


Providing critical products and ongoing support to customers by communicating frequently, understanding their changing business needs and ensuring key raw materials are multi-sourced when possible.


Maintaining adequate liquidity and financial flexibility by launching several cost-reduction initiatives and contingency plans to raise and conserve cash in all aspects of our operations and utilizing available federal relief such as the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act in the United States.


Koppers Holdings Inc.     2020 Annual Report


The full extent to which COVID-19 will adversely impact our business depends on future developments, which are highly uncertain and unpredictable, including new information concerning the ultimate severity of the outbreak and the effectiveness of actions globally to contain or mitigate its effects. Since March 2020, some of our facilities have temporarily curtailed operations as a result of government restrictions or as a result of our proactive measures to limit the potential spread of COVID-19 among our employees. Our business will continue to be impacted by such restrictions and protective measures for the foreseeable future. Our consolidated financial statements and discussion and analysis of financial condition and results of operations reflect estimates and assumptions made by us as of December 31, 2020. Events and changes in circumstances arising after December 31, 2020, including those resulting from the impacts of COVID-19, will be reflected in our estimates for future periods.

Refer to the Liquidity section of Management’s Discussion and Analysis for the impact of the global pandemic on our liquidity.

Railroad and Utility Products and Services

We provide our customers with treated and untreated wood products, rail joint bars and services primarily for the railroad markets in the United States and Canada. We also operate a railroad services business that conducts engineering, design, repair and inspection services primarily for railroad bridges in the U.S. and Canada. In addition, we supply treated utility poles for the utility sector in the United States and Australia. The primary end-markets for RUPS is the North American railroad industry, which has an installed base of approximately 450 million wood crossties, and the utility industry which utilizes wooden distribution and transmission poles. Both crossties and utility poles require periodic replacement.

Historically, North American demand for crossties had been in the range of 22 million to 25 million crossties annually. However, the crosstie replacement market has been significantly lower in recent years. According to the Railway Tie Association (“RTA”), the reported total crosstie installations in 2020 were approximately 18 million, of which 14 million were for Class I railroads. Throughout 2020, freight-rail traffic continued to decline, and passenger railroads and transit systems suspended or canceled operations due to lower ridership from stay-at-home restrictions. The reduced activity prompted larger track maintenance windows to be available and, as a result, the railroad industry is managing to offset lower volumes with increased productivity as certain railroads are taking advantage of reduced track time to increase maintenance on their infrastructure. Given the continuing uncertainties related to COVID-19, the RTA is forecasting modest increases of 2.7 percent in 2021 and 3.6 percent in 2022, primarily from the commercial market while Class I volumes are expected to remain at relatively similar demand levels.

For distribution poles, nearly half of the installed base is over 40 years old and demand has historically been in the range of two million to three million poles annually. On an overall basis, we believe that the rate at which utilities purchase utility poles will grow as they continue replacement programs within their service territories. As a whole, the key factors that drive growth in the utility poles market include growing global energy consumption as well as expansion of the global telecommunication industry. Now more than ever, utilities need to maintain their infrastructure to avoid interruptions in service as large sections of the population continue to work remotely due to the COVID-19 pandemic. As such, we anticipate that 2021 demand will be relatively stable to slightly higher, as the overall industry is trending toward expanded and upgraded transmission networks. Longer term, we are evaluating opportunities to potentially expand our market presence in the U.S. as well as certain overseas markets.

For the past several years, the major companies in the rail industry substantially reduced both operating and capital spending from peak spending levels, which had a negative impact on sales of various products and services that we provide to that industry. We currently supply all seven of the North American Class I railroads and have long-standing relationships with these customers. Approximately 70 percent of our North American sales are under long-term contracts and we believe that we are positioned to maintain or grow our current market position.

According to the American Association of Railroads (“AAR”), railroads began 2020 with uncertainty due to weakness in the manufacturing sector and lower port activity caused by trade disputes. In the early months of 2020, railroad traffic reported near-record declines, but ultimately rebounded to close to pre-pandemic levels by the end of the year, sparked by sharply higher grain and intermodal shipments along with the reopening of auto assembly plants. In 2020, total U.S. carload traffic decreased 12.9 percent from the prior year, while intermodal units declined by 1.8 percent. The combined U.S. traffic for carloads and intermodal units was lower by 7.2 percent than the prior year. Looking ahead to 2021, the AAR stated that a significant amount of ongoing network investments has made the industry more adaptable and better able to adjust to the demands of a wide range of operational and market conditions.

From a long-term perspective, we believe there remains an overall need for sustained investment in infrastructure and capacity expansion. We believe that with our vertical integration capabilities in wood treatment and strong customer relationships, we will ultimately benefit from increased demand.


In terms of raw materials, we expect the availability of pole supply to remain consistent even with lumber in high demand.  For untreated crossties, the supply can vary at times based upon weather conditions in addition to other factors. We have a nationwide wood procurement team that maintains close working relationships with a network of sawmills. We procure untreated crossties, either on behalf of our customers, or for our own inventory for future treating. We also procure switch ties and various other types of lumber used for railroad bridges and crossings. Untreated crossties go through a six- to nine-month air seasoning process before they are ready to be pressure treated. After the air seasoning process is complete, the crossties are pressure treated using creosote-only treatment or a combined creosote and borate treatment.

During any given year, there is a seasonal effect in the winter and spring months on our crosstie business depending on weather conditions for harvesting lumber and crosstie installation. While forestry has generally been deemed essential during the COVID-19 outbreak and tie demand has remained consistent, sawmills are being hampered by low demand in other key markets such as wood fibers used in palettes or shipping containers or mats for the oil and gas industry. So far to date, we have not experienced a noticeable impact as sawmills are continuing to produce poles and crossties to maintain their operations and cash flow. Consistent with typical seasonality, the RTA reports that the current availability of logs is slightly below the ideal rate, as is the outlook for log availability over the next six to 12 months.

Strategic Initiatives and Integration Synergies

As part of optimizing our business, we continue to evaluate a number of opportunities to improve efficiencies in our operational processes, people and facilities. With 16 North American RUPS treating facilities operating at less than full utilization, our goal is to either capture more volume through the existing facilities or consolidate our operating footprint. In June 2020, we announced the closure of our Denver, Colorado facility and, as such, in the second quarter of 2020 we recorded charges of $5.8 million for asset retirement obligations, fixed asset write-offs and severance. Concurrent with the decision to close the Denver facility, we announced our plan to modernize and upgrade parts of our treating network, specifically at our facility in North Little Rock, Arkansas, which will be primarily funded through proceeds from the sale of non-core assets, which includes the Denver facility.

Performance Chemicals

The largest geographic market for wood treating chemicals sold by our PC business is in North America, and the largest application for our products is the residential remodeling market. We also have a market presence in Europe, South America, Australia, New Zealand and Africa. We believe that PC is the largest global manufacturer and supplier of water-based wood preservatives and wood specialty additives to treaters that supply pressure treated wood products to large retailers and independent lumber dealers. These retailers and dealers, in turn, serve the residential, agricultural and industrial pressure-treated wood market. Our primary products are copper-based wood preservatives and fire-retardant chemicals (“FlamePro®”). Our copper-based wood preservatives include micronized copper azole (“MicroPro®”) and micronized pigments (“MicroShades®”). Applications for these products include decking, fencing, utility poles, construction lumber and other outdoor structures.

In North America, we are vertically integrated due to our manufacturing capabilities for copper compounds for our copper-based wood preservatives. We believe our vertical integration is part of our proprietary processes and reflects an important competitive advantage.

As most of the products sold by PC are copper-based products, changes in the price and availability of copper can have a significant impact on product pricing and margins. We attempt to moderate the variability in copper pricing over time by entering into hedging transactions for the majority of our copper needs, which primarily range from six months up to 36 months. These hedges typically match expected customer purchases and receive hedge accounting treatment. From time to time, we enter into forward transactions based upon long-term forecasted needs of copper. These forward positions are typically marked to market.

Product demand for our PC business has historically been closely associated with consumer spending on home repair and remodeling projects, and therefore, trends in existing home sales serve as a leading indicator. Overall, the market for existing homes are showing strong demand. According to the National Association of Realtors® (“NAR”), total existing-home sales grew in December for the fourth consecutive month. According to the NAR, total existing home sales increased 0.7 percent from November, and up 5.6 percent from a year ago. The increased buying activity is attributed to record-low interest rates and higher demand for existing homes, which includes buyers of vacation homes given the flexibility to work remotely. For 2020 as a whole, total home sales performed at their highest levels since 2006 and the momentum is expected to carry into 2021, with more buyers expected to enter the market.


Koppers Holdings Inc.     2020 Annual Report


According to the Leading Indicator of Remodeling Activity (“LIRA”) reported by the Joint Center for Housing Studies of Harvard University, there was 3.5 percent year-over-year growth in 2020 home renovation and repair expenditures. The LIRA projects annual growth in renovation and repair spending of 3.8 percent by year-end 2021. The remodeling market continues to benefit from a strong housing market – including accelerating growth in homebuilding, sales and home equity. In addition to routine replacement and repair projects, homeowners are likely to pursue more and larger discretionary home improvements this year as the broader economy recovers.

The Conference Board Consumer Confidence Index® improved moderately in January, after decreasing in December. The Index now stands at 89.3, up from 87.1 in December. In addition, consumers’ expectations regarding the economy and jobs showed improvement and the percent of consumers who said they intend to purchase a home in the next six months increased, suggesting that the pace of home sales should remain robust in early 2021.

During the pandemic, there has been a shift with more individuals spending more time in their homes, and as a result, big-box retailers are continuing to report strong demand for home improvement projects.  Consequently, we are benefiting from higher sales volumes of our water-borne treatment solutions used in residential treated wood products. In the U.S., we expect that lumber treaters will continue working to fill the demand backlog and retailers will continue replenishing their inventory levels during 2021.

Although the market data and projections for home improvements are continually changing, we are anticipating continued strong demand for residential treated wood in North America, primarily in the U.S. In looking at residential renovation markets, businesses are indicating a continued positive outlook, at least through mid-2021. In addition, the housing industry reported an increase in the number of buyers who are actively pursuing the purchase of a new or existing home, which supports a continued favorable outlook. As homeowners are focusing on the importance of their homes in a work-life environment and with interest rates at historically low levels, we expect the pace to continue into 2021.

Carbon Materials and Chemicals

The primary products produced by CMC are creosote, which is a registered pesticide in the United States and used primarily in the pressure treatment of railroad crossties, and carbon pitch, which is sold primarily to the aluminum industry for the production of carbon anodes used in the smelting of aluminum. We have reduced capacity in our CMC plants in North America and Europe over the past several years to levels required to meet creosote demand in North America for the treatment of railroad crossties. The CMC business currently supplies our North American RUPS business with its creosote requirements.

On September 30, 2020, we sold KJCC to Fangda Carbon New Material Co., Ltd and C-Chem Co., Ltd., a subsidiary of Nippon Steel Chemical & Material Co., Ltd. KJCC was located in Pizhou, Jiangsu Province, China and was a 75 percent-owned coal tar distillation company which was part of our CMC segment. The sales price was $107.0 million, subject to adjustments for cash, debt and working capital as defined in the sale and purchase agreement. The pre-tax gain on the sale of KJCC was $44.1 million and the after-tax gain on the sale was $35.8 million. The estimated final net cash proceeds to Koppers will total $65.2 million, after payment for Chinese capital gain taxes, transaction costs and estimated working capital adjustments.

In the third quarter of 2019, we ceased remaining production activities at our Follansbee, West Virginia facility and, in February 2021, we completed the sale of the facility. As a result of this action and other previously disclosed initiatives to reduce capacity in our CMC business, we expect additional restructuring and related charges to earnings of approximately $2 million to $5 million through 2021. The overall remaining future cash requirements for CMC plant closures still in progress are estimated to be approximately $10 million through 2021.

While the sale of carbon pitch remains a significant portion of our sales volume, the reduction of aluminum smelting capacity in the United States, Australia and Western Europe has led to sharply lower demand for carbon pitch over the past several years. Accordingly, we have experienced significantly lower sales volumes due to the reduction in aluminum production in parts of the world where the majority of our production facilities are located. However, beginning in 2018, aluminum production in the United States increased to some extent as tariffs were imposed on certain imported steel and aluminum products, which has stimulated restarts of previously idled capacity. This development has resulted in additional demand for carbon pitch in the United States that can likely only be sustained through a continuation of current trade policy.

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 also been reduced. For the past decade, the coal tar distillation industry has operated in an excess capacity mode, which further increased the competition for a limited amount of coal tar in North America. Over the past five years we have consolidated our operating footprint and significantly lowered production levels at the same time that we added distribution assets to move finished products from Europe to the United States more efficiently. As a result, our raw material needs in North America have been significantly less than historically required.


For the external markets served by our CMC business, we expect that North America and Europe will continue to be negatively impacted in 2021 by the COVID-19 pandemic. We have seen declines in industrial production markets which resulted in lower demand for our products. Carbon pitch and phthalic anhydride markets have softened due to declines in demand as manufacturing activity in North America and Europe significantly slowed. In addition, end market pricing for some products has been under pressure in certain regions due to the significant fall in worldwide oil prices.

Globally, coal tar raw material supply remains constrained due to reductions in blast furnace steel capacity. In North America, the pullback in steel production has led to lower domestic coal tar availability and an increase in raw material imports to North America at higher prices, while markets in Europe and Australia remain relatively steady. Overall, the cost of coal tar is decreasing in line with end markets but lagging by approximately three months.

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.

RUPS net sales for the year ended December 31, 2020 increased by $25.6 million, or three percent, compared to the prior year. The sales increase was primarily due to volume increases in the Class I crosstie market as well as the domestic and Australian utility pole markets, along with price increases in the domestic utility pole market in the current year. Sales of crossties increased by $16.8 million in the current year. These increases were offset, in part, by volume decreases in the commercial crosstie market and our maintenance-of-way businesses in the current year.

PC net sales for the year ended December 31, 2020 increased by $78.0 million, or 17 percent, compared to the prior year. The sales increase was due primarily to higher demand for copper-based preservatives in North America due to new customer additions and higher organic volumes driven by increased home repair and remodeling activities during the pandemic, along with an increase in sales volumes in our international markets resulting from pent-up demand due to several months of restrictions associated with the pandemic. These increases were partially offset by an unfavorable impact from foreign currency translation in the current year period of $5.1 million.

CMC net sales for the year ended December 31, 2020 decreased by $71.5 million, or 16 percent, compared to the prior year due mainly to lower sales prices for carbon pitch, carbon black feedstock, phthalic anhydride and naphthalene as a result of depressed oil prices in the current year period. Other contributing factors include lower sales volumes of carbon pitch in North America and naphthalene in Europe and Australia as a result of the economic conditions. These decreases were offset, in part, by volume increases of carbon pitch and carbon black feedstock in Australia.

Cost of sales as a percentage of net sales was 78 percent for the year ended December 31, 2020, compared to 80 percent in the prior year. Gross margin at PC was favorably impacted by higher sales volumes, a favorable sales mix and better absorption on higher production volumes. Improved margins at RUPS were due to a favorable sales mix in our Class I crosstie market and higher margins in our domestic utility pole and maintenance-of-way markets. Lower gross margins for CMC in the current year period were a result of lower sales prices for carbon pitch, carbon black feedstock, phthalic anhydride and naphthalene.

Depreciation and amortization charges for the year ended December 31, 2020 were consistent with the prior year.

Impairment and restructuring charges were $0.5 million higher when compared to the prior year period. The current year period primarily consists of charges for asset retirement obligations, fixed asset write-offs, severance, accelerated depreciation, demolition and other plant closure period costs related to the closure of our Denver, Colorado facility. The prior year period primarily consisted of asset retirement obligation charges, accelerated depreciation and inventory and fixed asset write-offs related to the closure of our Follansbee, West Virginia facility.


Koppers Holdings Inc.     2020 Annual Report

Selling, general and administrative expenses for the year ended December 31, 2020 were $5.2 million lower when compared to the prior year period due mainly to a decrease in consulting and professional service expenses, travel and facility related costs and employee related benefits.

Interest expense for the year ended December 31, 2020 was $12.8 million lower when compared to the prior year period primarily due to our lower average debt level and lower interest rates due to the significant decrease in LIBOR rates. In the third quarter of 2020, we used the net proceeds of the KJCC sale to reduce our borrowings under the Credit Facility.

Income taxes for the year ended December 31, 2020 were $21.0 million higher when compared to the prior year period. Both periods included various tax costs or benefits that significantly influenced income taxes.

For the year ended December 31, 2020, our income tax provision benefitted by a total of $13.3 million from our ability to utilize prior year carryforwards related to the limitation on our U.S. interest expense deduction in addition to increased prior year deductions for interest expense as a result of the CARES Act.

For the year ended December 31, 2019, our tax provision was favorably impacted due to a legal entity restructuring and tax audit closures. We completed a Dutch legal entity restructuring project, which resulted in an intra-entity transfer of certain intangible assets and intellectual property. This transaction resulted in the recognition of a deferred tax asset of $14.9 million. We also recorded a favorable tax benefit of $4.3 million for the year ended December 31, 2019 for the reversal of various unrecognized tax benefits due to the closure of a U.S. tax audit.

Income tax expense as a percentage of income before income taxes for the years ended December 31, 2020 and 2019 was 19.1 percent and zero percent, respectively. The increase is partially due to income before income taxes being $46.4 million higher when compared to the prior year period and the benefits from a Dutch legal entity restructuring recorded for the year ended December 31, 2019.

Discontinued operations for the year ended December 31, 2020 resulted in a loss of $3.9 million compared to income of $3.7 million in the prior year period due primarily to a year-over-year reduction in net sales of $104.2 million attributable to lower end market demand on our KJCC operations and only nine months of operations in 2020 due to the sale of the company.

Gain on sale of discontinued operations for the year ended December 31, 2020 is related to the sale of our KJCC business in China in September 2020. See Note 4 – “Plant Closures and Discontinued Operations” for further detail.
