Business Segments

Our business is composed of one segment, petroleum additives, which is primarily represented by Afton. The antiknock compounds business of Ethyl is reflected in the “All other” category. Each of these is discussed below.

Petroleum Additives—Petroleum additives are used in lubricating oils and fuels to enhance their performance in machinery, vehicles, and other equipment. We manufacture chemical components that are selected to perform one or more specific functions and combine those chemicals with other chemicals or components to form additive packages for

Table of Contents

use in specified end-user applications. The petroleum additives market is a global marketplace, with customers ranging from large, integrated oil companies to national, regional, and independent companies.

We believe our success in the petroleum additives market is largely due to our ability to deliver value to our customers through our products and our open, flexible, and collaborative working style. We accomplish this by understanding what our customers value and by applying our technical capabilities, formulation expertise, broadly differentiated product solutions, and global supply capabilities to satisfy the customers' needs. We invest significantly in research and development in order to meet our customers’ needs and to adapt to the rapidly changing environment for new and improved products and services.

We view the petroleum additives marketplace as being comprised of two broad product applications: lubricant additives and fuel additives. Lubricant additives are highly formulated chemical solutions that, when blended with base fluids, improve the efficiency, durability, performance, and functionality of mineral oils, synthetic oils, and biodegradable fluids, thereby enhancing the performance of machinery and engines. Fuel additives are chemical components that help oil refiners meet fuel specifications or formulated packages that improve the performance of gasoline, diesel, biofuels, and other fuels, resulting in lower operating costs, improved vehicle performance, and reduced emissions.

Lubricant Additives

Lubricant additives are essential ingredients for making lubricating oils. Lubricant additives are used in a wide variety of vehicle and industrial applications, including engine oils, transmission fluids, off-road powertrain and hydraulic systems, gear oils, hydraulic oils, and turbine oils, and virtually any other application where metal-to-metal moving parts are utilized. Lubricant additives are organic and synthetic chemical components that enhance wear protection, prevent deposits, and protect against the hostile operating environment of an engine, transmission, axle, hydraulic pump, or industrial machine.

Lubricants are widely used in operating machinery from transportation vehicles to heavy industrial equipment. Lubricants provide a layer of protection between moving mechanical parts. Without this layer of protection, the normal functioning of machinery would not occur. Effective lubricants reduce downtime and increase efficiency. Specifically, lubricants serve the following main functions:

•friction reduction—Friction is reduced by maintaining a thin film of lubricant between moving surfaces, preventing them from coming into direct contact with one another and reducing wear on moving machinery, thereby providing longer life and operational efficiency.

•heat removal—Lubricants act as coolants by removing heat resulting either from friction or through contact with other, higher temperature materials.

•containment of contaminants—Lubricants function by carrying contaminants away from the machinery and neutralizing the harmful impact of the by-products created by combustion.

The functionality of lubricants is created through an exact balance between a base fluid and performance enhancing additives. This balance is the goal of effective formulations achieved by experienced research and development professionals. We offer a full line of lubricant additive packages, each of which is composed of component chemicals specially selected to perform desired functions. We manufacture most of the chemical components and blend these components to create formulated additive packages designed to meet industry and customer specifications. Lubricant additive components are generally classified based upon their intended functionality, including:

•detergents, which clean moving parts of engines and machines, suspend oil contaminants and combustion by-products, and absorb acidic combustion products;

•dispersants, which serve to inhibit the formation of sludge and particulates;

•extreme pressure/antiwear agents, which reduce wear on moving engine and machinery parts;

•viscosity index modifiers, which improve the viscosity and temperature characteristics of lubricants and help the lubricant flow evenly to all parts of an engine or machine; and

•antioxidants, which prevent oil from degrading over time.

Table of Contents

We are one of the leading global suppliers of specially formulated lubricant additives that combine some or all of the components described above to develop our products. Our products are highly formulated, complex chemical compositions derived from extensive research and testing to ensure all additive components work together to provide the intended results. Our products are engineered to meet specifications prescribed by either the industry or a specific customer. Purchasers of lubricant additives tend to be integrated oil companies or independent compounders/blenders. We make no sales directly to end-users or to original equipment manufacturers (OEMs).

We view our participation in the lubricant marketplace in three primary areas: engine oil additives, driveline additives, and industrial additives. Our view is not necessarily the same way others view the market.

Engine Oil Additives—The largest submarket within the lubricant additives marketplace is engine oil additives which consists of additives designed for passenger cars, motorcycles, on and off-road heavy duty commercial equipment, locomotives, and large engines in ocean-going vessels. We estimate engine oil additives represent approximately 70% of the overall lubricant additives market volume.

The engine oil market’s primary customers include consumers, fleet owners, mining and construction companies, farmers, railroads, shipping companies, service dealers, and OEMs. The primary functions of engine oil additives are to reduce friction, prevent wear, control formation of sludge and oxidation, and prevent rust. Engine oil additives are typically sold to lubricant manufacturers who combine them with a base oil fluid to meet internal, industry, and OEM specifications.

Key drivers of engine oil additives demand are the number of vehicles on the road, total vehicle miles driven, fuel economy, the average age of vehicles on the road, drain intervals, engine and crankcase size, changes in engine design, and temperature and specification changes driven by the OEMs. The extension of drain intervals has generally offset increased demand due to higher vehicle population, new hardware, and more miles driven. Other key drivers include industrial production rates, agricultural output, mining and construction output, environmental regulations, and infrastructure investments of commercial companies. Afton offers products that enhance the performance of mineral, part-synthetic, and fully-synthetic engine oils.

Driveline Additives—The driveline additives submarket is comprised of additives designed for products such as transmission fluids, axle fluids, and off-road powertrain fluids. This submarket shares in the 30% of the market not covered by engine oil additives. Transmission fluids primarily serve as the power transmission and heat transfer medium in the area of the transmission where the torque of the drive shaft is transferred to the gears of the vehicle. Axle fluids lubricate gears and bearings in axles, and powertrain fluids are used in off-highway powertrain and hydraulic systems. Other products in this area include power steering fluids, shock absorber fluids, gear oils, and lubricants for heavy machinery. These products must conform to highly prescribed specifications developed by vehicle OEMs for specific models or designs. These additives are generally sold to oil companies for ultimate sale to vehicle OEMs for new vehicles (factory-fill), service dealers for aftermarket servicing (service-fill), retailers, and distributors.

Key drivers of the driveline additives marketplace are the number of vehicles manufactured, total number of vehicles in operation, drain intervals for transmission fluids and axle fluids, changes in engine and transmission design and temperatures, and specification changes driven by the OEMs.

Industrial Additives—The industrial additives submarket is comprised of additives designed for products for industrial applications such as hydraulic fluids, grease, industrial gear fluids, and industrial specialty applications, such as turbine oils. This submarket also shares in the 30% of the market not covered by engine oil additives. These products must conform to industry specifications, OEM requirements, and/or application and operating environment demands. Industrial additives are generally sold to oil companies, service dealers for after-market servicing, and distributors.

Key drivers of the industrial additives marketplace are gross domestic product levels and industrial production.

Fuel Additives

Fuel additives are chemical compounds that are used to improve both the oil refining process and the performance of gasoline, diesel, biofuels, and other fuels. Benefits of fuel additives in the oil refining process include reduced use of crude oil, lower processing costs, and improved fuel storage properties. Fuel performance additives enhance fuel economy, improve ignition and combustion efficiency, reduce emission particulates, maintain engine cleanliness, and protect against deposits in fuel injectors, intake valves, and the combustion chamber. Our fuel additives are extensively tested and designed to meet stringent industry, government, OEM, and individual customer requirements.

Many different types of additives are used in fuels. Their use is generally determined by customer, industry, OEM, and government specifications, and often differs from country to country. The types of fuel additives we offer include:

•gasoline performance additives, which clean and maintain key elements of the fuel delivery systems, including fuel injectors and intake valves, in gasoline engines;

•diesel fuel performance additives, which perform similar cleaning functions in diesel engines;

•cetane improvers, which increase the cetane number (ignition quality) in diesel fuel by reducing the delay between injection and ignition;

•stabilizers, which reduce or eliminate oxidation in fuel;

•corrosion inhibitors, which minimize the corrosive effects of combustion by-products and prevent rust;

•lubricity additives, which restore lubricating properties lost in the refining process;

•cold flow improvers, which improve the pumping and flow of distillate and diesel fuels in cold temperatures;

•octane enhancers, which increase octane ratings and decrease emissions; and

•static dissipating additives.

We offer a broad line of fuel additives worldwide and sell our products to major fuel marketers and refiners, as well as independent terminals and other fuel blenders.

Key drivers in the fuel additive marketplace include total vehicle miles driven, fuel economy, the introduction of new engine designs, regulations on emissions (both gasoline and diesel), quality of the crude oil slate and performance standards, and marketing programs of major oil companies.

Competition

We believe we are one of the four largest manufacturers and suppliers in the petroleum additives marketplace.

In the lubricant additives submarket, our major competitors are The Lubrizol Corporation (a wholly-owned subsidiary of Berkshire Hathaway Inc.), Infineum (a joint venture between ExxonMobil Chemical and Royal Dutch Shell plc), and Chevron Oronite Company LLC. There are several other suppliers in the worldwide market who are competitors in their particular product areas.

The fuel additives submarket is characterized by more competitors. While we participate in many facets of the fuel additives market, our competitors tend to be more narrowly focused. In the gasoline detergent market, we compete mainly against BASF, Chevron Oronite Company LLC, and The Lubrizol Corporation. In the diesel and refinery markets, we compete mainly against The Lubrizol Corporation, Infineum, BASF, Clariant Ltd., Dorf Ketal, and Innospec Inc. We also compete against other regional companies in the fuel additives marketplace.

The competition among the participants in these industries is characterized by the need to provide customers with cost effective, technologically-capable products that meet or exceed industry specifications. The need to continually increase technology performance and lower cost through formulation technology and cost improvement programs is vital for success in this environment.

All Other—The “All other” category includes the operations of the antiknock compounds business (primarily sales of antiknock compounds in North America), as well as certain contracted manufacturing and services performed by Ethyl. The Ethyl facility is located in Houston, Texas and is substantially dedicated to terminal operations related to antiknock compounds and other fuel additives. The financial results of the petroleum additives activities by Ethyl are reflected in the petroleum additives segment results. The “All other” category financial results include a service fee charged by Ethyl for its production services to Afton.

Human Capital

Our Values are the foundation of our company and support the inclusive and respectful culture we have established in all of our locations around the world. Our Values include:

•unquestioned integrity,

•respect for people,

•safety and environmental responsibility,

•partners with customers and suppliers,

•continuously improving quality,

•citizenship, and

•economic viability.

We place the highest level of commitment on safety and strive to operate our business every day focused on its importance. Keeping our employees safe is a management priority, and 2020 was a particularly challenging year in that regard because of the COVID-19 pandemic. While many of our employees were required to work from home due to government mandates, all of our facilities continued to be operational throughout 2020 since the chemical industry and our products are considered essential for the transportation of goods and services. For employees working onsite at our facilities, management invested significant time and effort to ensure the safety of our employees, above and beyond local government requirements and guidance, and to help mitigate the potential for transmission of COVID-19 onsite.

We have a diverse workforce, representative of the geographic regions in which we do business. We place a high value on diverse thoughts, skills, perspectives, cultures and knowledge because we believe that such diversity results in better business decision making. We employed 2,105 people at the end of 2020. Approximately 1,100 were located in the United States, 500 were in the Europe/Middle East/Africa/India region, 300 were in the Asia Pacific region, and 200 were in the Latin America region. Approximately 21% of our workforce is represented by unions.

When we hire new employees, our goal is that they stay with our company for the remainder of their career. Hiring the right people for the long-term and developing them for key roles is something we focus on. In order to be successful, we must attract and retain a highly qualified and technically competent workforce, including key employees in leadership positions. As technology changes in the petroleum additives industry are ongoing, the success of our business is very dependent upon our ability to attract and retain highly qualified scientific and technical personnel. In addition to utilizing our internal network, contacts, and specialized recruiters to identify and attract qualified personnel, we have established relationships with a number of universities globally and have intern and co-op programs in many of our locations.

Globally, approximately 18% of our employees have 20 years or more of service, and over the three year period from 2018 to 2020, our resignation rate was approximately 3%. We believe these measures demonstrate our success in hiring the right employees for the long-term and establishing a culture where respect for people is an everyday value.

As members of the ACC, Afton and Ethyl provide data on twelve metrics used to track environmental impact, safety, energy use, community outreach and emergency preparedness, greenhouse gas intensity, and product stewardship performance of the ACC member companies. These can be viewed at http://responsiblecare.americanchemistry.com/Performance-Results. The information on this website is not, and shall not be deemed to be, a part of this Annual Report on Form 10-K or incorporated by reference in this Annual Report on Form 10-K or any other filings we make with the Securities and Exchange Commission (SEC).

Governmental and Environmental Regulations

As a chemical company, we are subject to regulation by local, state, federal, and foreign governmental authorities specific to the production, distribution, management, and stewardship of chemicals.

In addition, in the United States and under similar foreign and state laws, we are subject to a variety of environmental laws and regulations, as well as environmental liabilities associated with the investigation and cleanup of hazardous substances. These liabilities may include personal injury, property damage, or natural resource damages arising from the release of, or exposure to, hazardous substances. They may be imposed on us in a range of situations without regard to violation of law or regulations. They may also be imposed jointly and severally, where one party may be held liable for a disproportionate share of the damages, up to and including the entire loss. These liabilities may include entities with any possible connection to the hazardous substances, including, for example, entities that formerly owned or operated a property or entities that arranged for disposal of hazardous substances from a property.

We believe we comply, in all material respects, with laws, regulations, statutes, and ordinances, including, but not limited to, those protecting the environment, as well as those related to the management and stewardship of chemicals. We have policies and procedures in place that establish regular reviews of our regulatory and environmental compliance and product stewardship, and actively monitor any significant existing or potential regulatory changes or environmental issues that could materially affect the company.

Our total accruals for environmental remediation, dismantling, and decontamination were approximately $10 million at December 31, 2020 and $11 million December 31, 2019. As new technology becomes available, it may be possible to reduce accrued amounts. While we believe that we are currently fully accrued for known environmental issues, it is possible that unexpected future costs could have a significant financial impact on our financial position, results of operations, and cash flows.

The costs of complying with existing environmental, health, and safety laws and regulations as they pertain to our products and operations, including remediation, closure, and postclosure costs, are primarily included in cost of goods sold. We spent approximately $29 million in both 2020 and 2019, and $30 million in 2018 for ongoing environmental operating and clean-up costs, excluding depreciation of previously capitalized expenditures.

In addition to the ongoing environmental compliance costs and the costs to remediate contaminated sites, worldwide capital expenditures for pollution prevention and safety projects were $17 million in 2020, $8 million in 2019, and $10 million in 2018. The increase in 2020 resulted primarily from a planned modernization project at one of our manufacturing facilities. We expect expenditures will return to more historical levels for 2021.

The costs of complying with governmental pollution prevention and safety regulations are subject to:

•potential changes in applicable statutes and regulations (or their enforcement and interpretation);

•uncertainty as to the success of anticipated solutions to pollution problems;

•uncertainty as to whether additional expense may prove necessary; and

•potential for emerging technology to affect remediation methods and reduce associated costs.

ITEM 1A. RISK FACTORS

Our business is subject to many factors that could have a material adverse effect on our future performance, results of operations, financial condition, or cash flows and could cause our actual results to differ materially from those expressed or implied by forward-looking statements made in this Annual Report on Form 10-K. Those risk factors are outlined below.

Table of Contents

Market and Supply Chain Risks

•Lack of availability of raw materials, including sourcing from some single suppliers, could negatively impact our ability to meet customer demand.

The chemical industry can experience limited supply of certain materials. In addition, in some cases, we choose to source from a single supplier. Any significant disruption in supply, for any reason, could adversely affect our ability to obtain raw materials, which in turn could adversely affect our ability to ensure continued supply for our customers and to meet customer demand.

•Sudden or sharp changes in the prices of and/or demand for raw materials may adversely affect our profit margins.

We utilize a variety of raw materials in the manufacture of our products, including base oil, polyisobutylene, antioxidants, alcohols, solvents, sulfonates, friction modifiers, olefins, and copolymers. We may also enter into contracts which commit us to purchase some of our more critical raw materials based on anticipated demand. Our profitability is sensitive to changes in the quantities of raw materials we may need and the costs of those materials which may be caused by changes in supply, demand or other market conditions, over which we have little or no control. Political and economic conditions globally have caused, and may continue to cause, our demand for and the cost of our raw materials to fluctuate. War, armed hostilities, terrorist acts, civil unrest, or other incidents may also cause a sudden or sharp change in our demand for and the cost of our raw materials. We cannot assure that we will be able to pass on to our customers any future increases in raw material costs in the form of price increases for our products. If our demand for raw materials were to decline such that we would not have need for the quantities required to be purchased under commitment agreements, we could incur additional charges that would affect our profitability.

•Competitive pressures could adversely affect our margins and profitability.

We face significant competition in all of the product lines and markets in which we compete. We expect that our competitors will develop and introduce new and enhanced products, which could cause a decline in the market acceptance of certain products we manufacture. In addition, as a result of price competition, we may be compelled to reduce the prices for some of our products, which could adversely affect our margins and profitability. Some of our competitors may also have greater financial, technological, and other resources than we have and may be able to maintain greater operating and financial flexibility than we are able to maintain. As a result, these competitors may be able to better withstand changes in conditions within our industry, changes in the prices for raw materials, and changes in general economic conditions.

•We rely on a small number of significant customers concentrated in the lubricant and fuel industries. The loss of sales to any of these customers could significantly reduce our revenues and negatively affect our profitability.

Our principal customers are multinational oil companies in the lubricant and fuel industries. These industries are characterized by the concentration of a few large participants. This concentration of customers affects our overall risk profile, since our customers will be similarly affected by changes in economic, geopolitical, and industry conditions. Many factors affect the level of our customers’ spending on our products, including, among others, general business conditions, changes in technology, interest rates, oil prices, and consumer confidence in future economic conditions. A sudden or protracted downturn in these industries could adversely affect the buying power of, and purchases by, our customers. The loss of a significant customer or a material reduction in purchases by a significant customer could reduce our revenues and negatively affect our profitability.

Operational Risks

•A disruption in the availability or capacity of distribution systems could negatively impact our ability to meet our customers’ needs and affect our competitive position.

We rely on a variety of modes of transportation to deliver products to our customers, including rail cars, cargo ships, and trucks. We depend upon the availability of a distribution infrastructure to deliver our products in a safe and timely manner. Any disruptions in this infrastructure network, whether caused by human error, accidents, deliberate acts of violence, limitations on capacity, repairs and improvements to infrastructure components, earthquakes, storms, or other natural disasters, could adversely affect our ability to meet customer demand.

•A significant disruption or disaster at one of our production facilities, including those facilities which are sole producers of certain of our products, could result in our inability to meet production requirements and projected customer demand. This could potentially result in us incurring significant liabilities.

We are dependent upon the continued safe operation of our production facilities. Several of the products we sell are produced only in one location. A prolonged disruption or disaster at one of our facilities could result in our inability to meet production requirements.

Our production facilities are subject to various hazards associated with the manufacturing, handling, storage, and transportation of chemical materials and products, including some that are reactive, explosive, and flammable. Such hazards could include leaks, ruptures, chemical spills, explosions, or fires which result in the discharge or release of toxic or hazardous substances or gases; mechanical failures; unscheduled downtime; and environmental hazards. These sites may also experience significant disruptions in operations due to inclement weather, natural disasters, flooding, and levee breaches. Many of these hazards could cause a disruption in the production of our products and may diminish our ability to meet output goals. We cannot assure that our facilities will not experience these types of hazards and disruptions in the future or that these incidents will not result in production delays and affect our ability to meet production requirements. Any such disruptions or disasters at our facilities could result in us losing revenue or not being able to maintain our relationships with our customers.

Additionally, some of the hazards mentioned above could result in significant liabilities related to personal injury and loss of life; severe damage to, or destruction of, property and equipment; and environmental contamination.

•Our research and development efforts are costly and may not succeed, which could impair our ability to meet our customers’ needs, affect our competitive position, and result in a loss of market share.

The petroleum additives industry is subject to periodic technological change, changes in performance standards, and ongoing product improvements. Further, technological changes in some or all of our customers’ products or processes may make our products obsolete. As a result, the life cycle of our products is often hard to predict. In order to maintain our profits and remain competitive, we must effectively respond to technological changes in our industry and successfully develop, manufacture, and market new or improved products in a cost-effective and timely manner. As a result, we must commit substantial resources each year to research and development to maintain and enhance our technological capabilities and meet our customers’ changing needs. Ongoing investments in research and development for future products could result in higher costs without a proportional increase in profits. Additionally, for any new product program, there is a risk of technical or market failure in which case we may not be able to develop the new commercial products needed to maintain and enhance our competitive position, or we may need to commit additional resources to new product development programs. Moreover, new products may have lower margins than the products they replace.

•Our failure to protect our intellectual property rights could harm our competitive position and could adversely affect our future performance and growth.

Protection of our proprietary processes, methods, compounds, and other technologies is important to our business. We depend upon our ability to develop and protect our intellectual property rights to distinguish our products from those of our competitors. Failure to protect our existing intellectual property rights may result in the loss of valuable technologies or having to pay other companies for infringing on their intellectual property rights. The inability to continue using certain of our trademarks or service marks could result in the loss of brand recognition, and could require us to devote additional resources to advertise, rebrand our products, and market our brands. See Item 1, “Business-Intellectual Property.”

We rely on a combination of patent, trade secret, trademark, and copyright laws, as well as judicial enforcement, to protect our intellectual property and technologies. We cannot assure that the measures taken by us to protect these assets and rights will provide meaningful protection or that adequate remedies will be available in the event of an unauthorized use or disclosure of our trade secrets or manufacturing expertise. We cannot assure that any of our intellectual property rights will not be challenged, invalidated, circumvented, or rendered unenforceable. In addition, we have manufacturing operations in countries where we may not have the same strength of intellectual property protection and enforcement as in North America or Europe, resulting in a greater risk of a third party appropriating our intellectual property.

Furthermore, we cannot assure that any pending patent application filed by us will result in an issued patent, or if patents are issued to us, that those patents will provide meaningful protection against competitors or against competitive technologies. We could face patent infringement claims from our competitors or others alleging that our processes or products infringe on their proprietary technologies. If we were found to be infringing on the proprietary technology of others, we may be liable for damages, and we may be required to change our processes, redesign our products partially or completely, pay to use the technology of others, or stop using certain technologies or producing the infringing product entirely. Even if we ultimately prevail in an infringement suit, the existence of the suit could prompt customers to switch to products that are not the subject of infringement suits. We may not prevail in any intellectual property litigation and such litigation may result in significant legal costs or otherwise impede our ability to produce and distribute key products.

We also rely on unpatented proprietary manufacturing expertise, continuing technological innovation and other trade secrets to develop and maintain our competitive position. While we generally enter into confidentiality agreements with our employees and third parties to protect our intellectual property, we cannot assure that our confidentiality agreements will not be breached, that they will provide meaningful protection for our trade secrets and proprietary manufacturing expertise, or that adequate remedies will be available in the event of an unauthorized use or disclosure of our trade secrets or manufacturing expertise.

In addition, our trade secrets and know-how may be improperly obtained by other means, such as a breach of our information technology security systems or direct theft. Any unauthorized disclosure of our material know-how or trade secrets could adversely affect our business and results of operations.

•In order to be successful, we must attract and retain a highly qualified workforce, including key employees in leadership positions.

The success of our business is highly dependent on our ability to attract and retain highly qualified personnel to support our research and development efforts and our agility in effectively responding to technological changes in our industry. To the extent that the demand for skilled personnel exceeds supply, we could experience higher labor, recruiting, or training costs in order to attract and retain such a work force. We compete with other companies, both within and outside of our industry, for qualified technical and scientific personnel such as chemical, mechanical, and industrial engineers. To the extent that we lose experienced personnel through wage competition, normal attrition (including retirement), or other means, we must be able to attract qualified candidates to fill those positions and successfully manage the transfer of critical knowledge from those individuals leaving our company. Our inability to maintain a highly qualified technical workforce could adversely affect our competitive position and result in a loss of market share.

Table of Contents

We also must manage leadership development and succession planning throughout our business. To the extent that we are unable to attract, develop, and retain leadership talent successfully, we could experience business disruptions that adversely affect our ability to grow our business.

•An information technology system failure may adversely affect our business.

We rely on information technology systems, some of which are managed by third parties, to transact our business. An information technology system failure due to computer viruses, internal or external security breaches, cybersecurity attacks, power interruptions, hardware failures, fire, natural disasters, human error or other causes could disrupt our operations, lead to loss of confidential information (such as the personally identifiable information of individuals, including our employees) or intellectual property, and/or prevent us from being able to process transactions with our customers, operate our manufacturing facilities, and properly report transactions in a timely manner. Cybersecurity threats, in particular, continue to increase in sophistication. We have security processes and disaster recovery plans in place to mitigate these threats. Nonetheless, these may not be sufficient to identify a threat in a timely manner or protect our operations from such a threat, potentially resulting in financial, legal, business, or reputational damage to our company.

A significant, protracted information technology system failure may adversely affect our results of operations, financial condition, or cash flows.

Furthermore, we are subject both to changing cybersecurity rules and evolving data privacy rules and regulations, such as the European Union's General Data Protection Regulation, in countries, states, and jurisdictions where we conduct business. The failure to comply with these rules and regulations could result in significant financial penalties or increase our cost of doing business.

•The occurrence or threat of extraordinary events, including domestic or international terrorist attacks, hostilities, or health-related epidemics, may disrupt our operations, decrease demand for our products, and increase our expenses.

Chemical-related assets may be at greater risk of future terrorist attacks than other possible targets in the United States and throughout the world. Federal legislation has imposed significant site security requirements, specifically on chemical manufacturing facilities. Federal regulations have also been enacted to increase the security of the transportation of hazardous chemicals in the United States. The enactment of further federal regulations to increase the security of the transportation of hazardous chemicals in the United States could result in additional costs.

The occurrence of extraordinary events, including future terrorist attacks, the outbreak or escalation of hostilities, or a health-related epidemic cannot be predicted, but their occurrence can be expected to negatively affect the economy in general, as well as the markets for our products, and can result in production downtime. In addition, the damage from a direct attack on our assets or assets used by us could include loss of life or property damage, and available insurance coverage may not be sufficient to cover all of the damage incurred or, if available, may be prohibitively expensive.

•The COVID-19 pandemic has had an impact on our financial results and could have a material adverse effect on our results of operations, financial position, and cash flows in the future.

The COVID-19 pandemic has created significant uncertainty and economic disruption. The extent to which it will continue to impact our business, results of operations, financial position, and cash flows is difficult to predict and dependent upon many factors over which we have no control. These factors include, but are not limited to, the duration and severity of the pandemic; the effectiveness, acceptance, and speed of application of the recently developed vaccines; government restrictions on businesses and individuals; the impact of the pandemic on our customers’ businesses and the resulting demand for our products; the impact on our suppliers and supply chain network; the impact on U.S. and global economies and the timing and rate of economic recovery; and potential adverse effects on the financial markets.

•We face risks related to our foreign operations that may negatively affect our business.

In 2020, sales to customers outside of the United States accounted for over 65% of consolidated net sales. We do business in all major regions of the world, some of which do not have stable economies or governments. In particular, we sell and market products in countries experiencing political and/or economic instability in the Middle East, Asia Pacific, Latin America, and Europe. Our international operations are subject to international business risks, including unsettled political conditions, expropriation, import and export restrictions, trade policies, increases in royalties, exchange controls, national and regional labor strikes, taxes, government royalties, inflationary or unstable economies, currency exchange rate fluctuations, and changes in laws and policies governing operations of foreign-based companies (such as restrictions on repatriation of earnings or proceeds from liquidated assets of foreign subsidiaries). The occurrence of any one or a combination of these factors may increase our costs or have other adverse effects on our business.

The United Kingdom’s June 2016 referendum decision to withdraw from the European Union (EU) effective January 31, 2020, commonly known as Brexit, has resulted in uncertainty for our European operations regarding the extent to which our operations and financial performance will be affected immediately and in the longer term. On December 24, 2020, in advance of the transition period ending on December 31, 2020, the United Kingdom (U.K.) and the EU reached an agreement on the future relationship. The agreement is complex, addressing a wide-range of matters, but notably trade on goods between the U.K. and EU will continue tariff-free. Our key manufacturing facilities in the EU are not in the U.K. Therefore, goods movements continue to be predominantly within the EU post-Brexit which means that existing key trade agreements will continue to apply. However, Brexit has brought new ways of working and uncertainty for U.K. business, logistics providers, and customs brokers for international business when the U.K. is involved in the supply chain. While this has resulted in some disruption to our operations in the U.K., no material additional risks have become apparent. We are continuing to monitor and evaluate changes in legislation and trading practices in order to mitigate any potential risks to our operations.

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

We maintain property, business interruption, and casualty 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 liabilities covered. We may incur losses beyond the limits, or outside the coverage, of our insurance policies, including liabilities for environmental remediation. 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.

Legislative and Regulatory Risks

•Our business could be adversely affected by current and future governmental regulation.

We are subject to regulation by local, state, federal, and foreign governmental authorities. In some circumstances, before we may sell certain products, these authorities must approve these products, our manufacturing processes, and our facilities. We are also subject to ongoing reviews of our products, manufacturing processes, and facilities by governmental authorities. Any delay in obtaining or failure to obtain or maintain these approvals would adversely affect our ability to introduce new products and generate sales from those products.

New laws and regulations, including climate change regulations, may be introduced in the future and could result in additional compliance costs, which could prevent or inhibit the development, distribution, and sale of our products. If we fail to comply with applicable laws and regulations, we may be subject to civil remedies, including fines, injunctions, recalls, or seizures.

We are subject to the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act, and similar anti-bribery laws in other jurisdictions which generally prohibit companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or retaining business. We are also subject to export and import laws and regulations which restrict trading with embargoed or sanctioned countries and certain individuals. Although we have policies and procedures designed to facilitate compliance with these laws and regulations, our employees, contractors and agents may take actions in violation of our policies. Any such violation, even if prohibited by our policies, could adversely affect our business and/or our reputation.

Table of Contents

•Legal proceedings and other claims could impose substantial costs on us.

We are involved in numerous administrative and legal proceedings that result from, and are incidental to, the conduct of our business. From time to time, these proceedings involve environmental, product liability, tetraethyl lead, premises asbestos liability, and other matters. See Item 3, “Legal Proceedings.” There is no assurance that our available insurance will cover these claims, that our insurers will not challenge coverage for certain claims, or that final damage awards will not exceed our available insurance coverage.

At any given time, we are involved in claims, litigation, administrative proceedings, and investigations of various types in a number of jurisdictions involving potential environmental liabilities, including clean-up costs associated with waste disposal sites, natural resource damages, property damage, and personal injury. We cannot assure that the resolution of these environmental matters will not have an adverse effect on our results of operations, financial condition, or cash flows.

•Environmental matters could have a substantial negative impact on our business.

As a manufacturer and distributor of chemical products, we are generally subject to extensive local, state, federal, and foreign environmental, safety, and health laws and regulations concerning, among other things, emissions to the air; discharges to land and water; the generation, handling, treatment, and disposal of hazardous waste and other materials; and remediation of contaminated soil, as well as surface and ground water. Our operations entail the risk of violations of those laws and regulations, many of which provide for substantial fines and criminal sanctions for violations. We believe that we comply in all material respects with laws, regulations, statutes, and ordinances protecting the environment, including those related to the discharge of materials. However, we cannot assure that we have been or will be at all times in compliance with all of these requirements.

In addition, these requirements, and the enforcement or interpretation of these requirements, may become more stringent in the future. Although we cannot predict the ultimate cost of compliance with any such requirements, the costs could be material. Noncompliance could subject us to material liabilities, such as government fines, damages arising from third-party lawsuits, or the suspension and potential cessation of non-compliant operations. We may also be required to make significant site or operational modifications at substantial cost. Future developments could also restrict or eliminate the use of or require us to make modifications to our products.

There may be environmental problems associated with our properties of which we are unaware. The discovery of environmental liabilities attached to our properties could have an adverse effect on our business even if we did not create or cause the problem.

We may also face liability arising from current or future claims alleging personal injury, product liability, or property damage due to exposure to chemicals or other hazardous substances, such as premises asbestos, at or from our facilities. We may also face liability for personal injury, product liability, property damage, natural resource damage, or clean-up costs for the alleged migration of contaminants or hazardous substances from our facilities or for future accidents or spills.

In some cases, we have been identified, and in the future may be identified, as a potentially responsible party (PRP) in connection with state and federal laws regarding environmental clean-up projects. As a PRP, we may be liable for a share of the costs associated with cleaning up hazardous waste sites, such as a landfill to which we may have sent waste.

The ultimate costs and timing of environmental liabilities are difficult to predict. Liability under environmental laws relating to contaminated sites can be imposed retroactively and on a joint and several basis. A liable party could be held responsible for all costs at a site, whether currently or formerly owned or operated, regardless of fault, knowledge, timing of the contamination, cause of the contamination, percentage of contribution to the contamination, or the legality of the original disposal. We could incur significant costs, including clean-up costs, natural resource damages, civil or criminal fines and sanctions, and third-party claims, as a result of past or future violations of, or liabilities under, environmental laws.

Table of Contents

Financial and Economic Risks

•A substantial amount of indebtedness could adversely impact our business and limit our operational and financial flexibility.

We have incurred, and may in the future incur, significant amounts of indebtedness to support our operations. Our indebtedness could, among other things, require us to dedicate a substantial portion of our cash flow to repaying our indebtedness, thus reducing the amount of funds available for other general corporate purposes; limit our ability to borrow additional funds necessary for working capital, capital expenditures or other general corporate purposes; and limit our flexibility in planning for, or reacting to, changes in our business.

Our ability to make payments on or refinance our indebtedness will depend on our ability to generate cash from operations in the future. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory, and other factors that are beyond our control.

We cannot guarantee that our business will generate sufficient cash flow from operations or that future borrowings will be available to us under our credit facilities in an amount sufficient to enable us to repay our debt, service our indebtedness, or to fund other liquidity needs. Furthermore, substantially all of our business is conducted through our subsidiaries, and we cannot guarantee that our subsidiaries will be able to distribute funds to us for these purposes.

We may need to refinance all or a portion of our indebtedness on or before maturity. We cannot guarantee that we will be able to refinance any of our indebtedness on commercially reasonable terms or at all.

Additionally, our debt instruments contain restrictive covenants. These covenants may constrain our activities and limit our operational and financial flexibility. The failure to comply with these covenants could result in an event of default.

Our revolving credit facility utilizes the London Interbank Offered Rates (LIBOR) in establishing interest rates on the facility. LIBOR is the subject of recent proposals for reform, which may cause LIBOR to disappear entirely or perform differently than in the past. The consequences of these developments cannot be entirely predicted at this time, but could result in an increase in the cost of borrowings under the revolving credit facility.

•We are exposed to fluctuations in foreign exchange rates, which may adversely affect our results of operations.

We conduct our business in the local currency of many of the countries in which we operate. The financial condition and results of operations of our foreign operating subsidiaries are reported in the relevant local currency and then translated to U.S. Dollars at the applicable currency exchange rate for inclusion in our consolidated financial statements. Changes in exchange rates between these foreign currencies and the U.S. Dollar will affect the recorded amounts of our assets and liabilities, as well as our revenues, costs, and operating margins. The primary foreign currencies in which we have exchange rate fluctuation exposure are the European Union Euro, British Pound Sterling, Japanese Yen, Chinese Renminbi, Indian Rupee, Singapore Dollar, Mexican Peso, Australian Dollar, and Canadian Dollar. Exchange rates between these currencies and the U.S. Dollar have fluctuated significantly in recent years and may do so in the future.

•We could be required to make additional contributions to our pension plans, which may be underfunded due to any underperformance of equity markets.

Our pension plan asset allocation is predominantly weighted towards equities. Cash contribution requirements to our pension plans are sensitive to changes in our plans’ actual return on assets. Reductions in our plans’ return on assets due to poor performance of equity markets could cause our pension plans to be underfunded and require us to make additional cash contributions.

Table of Contents

Acquisition and Investment Risks

•We may be unable to consummate a proposed acquisition transaction due to a lack of regulatory approval or the failure of one or more parties to satisfy conditions to close. In addition, we may not be able to realize the expected benefits from recent or future acquisitions or from investments in our infrastructure, or it may take longer to realize those benefits than originally planned. The inability to achieve our objectives related to these activities could result in unanticipated expenses and losses.

As part of our business growth strategy, we intend to continue pursuing acquisitions and investing in our infrastructure. Our ability to implement these components of our growth strategy will be limited by our ability to identify appropriate acquisition or joint venture candidates; our ability to consummate proposed transactions due to a lack of regulatory approval or the failure of one of the parties to a transaction to satisfy conditions required for closing; and the availability of financial resources, including cash and borrowing capacity. When we acquire new businesses or invest in infrastructure improvements (for example, building new plant facilities), we consider the benefits we expect to realize and time frames over which we will realize those benefits. The expenses incurred in completing these types of activities, the time it takes to integrate the activities into our ongoing business, or our failure to realize the expected benefits from the activities in the planned time frames could result in unanticipated expenses and losses. The process of integrating acquired operations into our existing operations may result in unforeseen operating difficulties and may require significant financial resources that would otherwise be available for the ongoing development or expansion of existing operations.

PART II

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our common stock, with no par value, has traded on the New York Stock Exchange (NYSE) under the symbol “NEU” since June 21, 2004 when we became the parent holding company of Ethyl, Afton, NewMarket Services, NewMarket Development, and their subsidiaries. We had 1,891 shareholders of record at January 31, 2021.

On December 13, 2018, our Board of Directors approved a share repurchase program authorizing management to repurchase up to $500 million of NewMarket's outstanding common stock effective January 1, 2019 until December 31, 2021, as market conditions warrant and covenants under our existing debt agreements permit. We may conduct the share repurchase in the open market, in privately negotiated transactions, through block trades or pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934. The repurchase program does not require NewMarket to acquire any specific number of shares and may be terminated or suspended at any time. At December 31, 2020, approximately $399 million remained available under the 2018 authorization. There were no purchases during the fourth quarter of 2020 under this authorization.

Cash dividends declared and paid totaled $7.60 per share for the year ended December 31, 2020 and $7.30 per share for the year ended December 31, 2019. The declaration and payment of dividends is subject to the discretion of our Board of Directors. Future dividends will depend on various factors, including our financial condition, earnings, cash requirements, legal requirements, restrictions in agreements governing our outstanding indebtedness, and other factors deemed relevant by our Board of Directors.

Notes to the Five Year Summary

(1)Other income (expense), net for each year included the components of net periodic benefit cost (income), except for service costs, amounting to income of $26 million in 2020, $23 million in 2019, $19 million in 2018, $14 million in 2017 and $8 million in 2016. The amount for 2020 also included a gain of $16 million related to the sale of a non-operating parcel of real estate. In addition, 2016 included a loss on the Goldman Sachs interest rate swap, as well as several other small items. The loss on the interest rate swap was $5 million for 2016. We terminated the interest rate swap on September 7, 2016. We did not use hedge accounting to record the interest rate swap, and accordingly, any change in the fair value was immediately recognized in earnings.

(2)On December 22, 2017, the United States enacted tax legislation commonly known as the Tax Cuts and Jobs Act, which required a one-time tax in 2017 on the deemed repatriation of previously deferred foreign earnings and reduced the U.S. corporate tax rate from 35% to 21% beginning in 2018. We recorded a net tax expense of $31 million in 2017 as a result.

In light of these risks and uncertainties, any forward-looking statement made in this discussion or elsewhere, might not occur.

OVERVIEW

When comparing the results of the petroleum additives segment for 2020 with 2019, both net sales and operating profit decreased primarily as a result of the economic disruption from the COVID-19 pandemic. Net sales for 2020 decreased 8.0% primarily due to lower lubricant additives and fuel additives product shipments, as well as decreased selling prices. Petroleum additives operating profit for 2020 was 7.2% lower reflecting lower product shipments and changes in selling prices, as well as higher conversion costs, partially offset by improved raw material costs.

Our operations generate cash that is in excess of the needs of the business. We continue to invest in and manage our business for the long-term with the goal of helping our customers succeed in their marketplaces. Our investments continue to be in organizational talent, technology development and processes, and global infrastructure, consisting of technical centers, production capability, and geographic expansion.

IMPACT OF THE COVID-19 PANDEMIC AND CURRENT ECONOMIC ENVIRONMENT

Petroleum additives operating results for 2020 have been marked by economic uncertainty resulting from the ongoing effects of the COVID-19 pandemic and the related restrictions on the movement of people, goods and services. While

Table of Contents

we have continued to operate throughout the year in each of our regions, we have at various times experienced significant changes in some of the key drivers that affect the performance of our business. During the second quarter of 2020, government and business shutdowns in North America and Europe led to a precipitous drop in vehicle miles driven and auto production, with gasoline consumption in the United States dropping to its lowest point in over 50 years. With less travel and fewer miles driven, combined with automobile plant closures, global demand for our products declined substantially, except in our Asia Pacific region where demand remained relatively stable throughout the year. As restrictions eased and economies reopened in the second half of 2020, global production of automobiles began to rebound and gasoline consumption and miles driven showed steady improvement in most countries, including the United States. Late in the fourth quarter, renewed restrictions on travel and work in certain countries had a negative effect on our business. The pace and stability of improvement in demand for our products will continue to depend heavily on economic recovery and the rate at which government restrictions are lifted and remain lifted.

With only a very few government-ordered, short-term exceptions, all of our locations around the world, including our manufacturing and research and development facilities, have continued to operate safely and without interruption during the pandemic, and we expect them to continue to do so. Raw material sourcing has not been significantly impacted and we do not expect that to change over the coming months. The transportation industry continues to operate and our products are currently being delivered to our customers.

Our financial position remains strong. We have sufficient access to additional capital if needed, including our new $900 million revolving credit facility we entered into in March 2020, and we do not anticipate any issues with meeting the covenants in our debt agreements. Our major capital projects are continuing to progress substantially as planned.

The chemical industry and our products are recognized as essential for the transportation of goods and services. Our business continuity planning process focuses our efforts on managing through this challenging time and helping our customers do the same. As we are a global company and can leverage the knowledge and experience of our personnel in facilities across the world, we do not expect to experience negative impacts related to short-term travel and border restrictions. As we operate in the chemical industry, we continue to be focused on protecting the health and safety of our employees and have procedures in place at each of our operating facilities to help ensure their well-being.

RESULTS OF OPERATIONS

Management's discussion and analysis of our results of operations is presented below for the comparative periods of 2020 versus 2019. The discussion and analysis of our results of operations for 2019 compared to 2018 is available in Item 7 of our 2019 Annual Report on Form 10-K.

Net Sales

Our consolidated net sales for 2020 amounted to $2.0 billion, a decrease of $179 million, or 8.2% from 2019.

No single customer accounted for 10% or more of our total net sales in 2020, 2019, or 2018.

The following table shows net sales by segment and product line for each of the last three years.


	Years Ended December 31,

Petroleum Additives - The regions in which we operate include North America (the United States and Canada), Latin America (Mexico, Central America, and South America), Asia Pacific, and the Europe/Middle East/Africa/India (EMEAI) region. The percentage of net sales being generated in the regions has remained fairly consistent over the past

Table of Contents

three years, with some limited fluctuation due to various factors, including the impact of regional economic trends. North America and EMEAI both represent around 35% of our petroleum additives net sales, while Asia Pacific contributes about 25% and Latin America represents the remaining amount. As shown in the table above, lubricant additives net sales and fuel additives net sales compared to total petroleum additives net sales has remained substantially consistent over the past three years.

Petroleum additives net sales for 2020 of $2.0 billion were approximately 8.0% lower than 2019 levels. The decrease was across all regions except the Latin America region, which was substantially even with 2019 levels. The North America region represented nearly 50% of the petroleum additives decrease in net sales, while the Asia Pacific and EMEAI regions represented about 25% each. The decrease in petroleum additives net sales was predominantly the result of the economic disruption due to the COVID-19 pandemic, including lower demand for petroleum additives products reflecting the restrictions across the world on the movement of people, goods, and services.

The approximate components of the petroleum additives decrease in net sales of $174 million when comparing 2020 to 2019 are shown below in millions.

Lubricant additives shipments	(46)
Fuel additives shipments	(46)

Net sales for year ended December 31, 2020	$	2,002

Petroleum additives shipments accounted for a $92 million decrease in net sales between 2019 and 2020. Lower selling prices, partially offset by a favorable foreign currency impact, resulted in a decrease in net sales of $82 million when comparing the two years. The United States Dollar weakened against the Euro when comparing 2020 and 2019, which resulted in most of the favorable foreign currency impact to net sales in 2020.

On a worldwide basis, the volume of product shipments for petroleum additives decreased 5.2% when comparing 2020 with 2019. The decreases in shipments were in both lubricant additives and fuel additives. Most of the decrease in lubricant additives was in the Asia Pacific region, with small decreases in the North America and EMEAI regions offset by a small increase in the Latin America region. The North America and EMEAI regions represented most of the decrease in fuel additive product shipments. We believe the decrease in product shipments during 2020 substantially resulted from the impact of the COVID-19 pandemic.

All Other - The “All other” category includes the operations of the antiknock compounds business, and certain contracted manufacturing and services performed by Ethyl.

Segment Operating Profit

NewMarket evaluates the performance of the petroleum additives business based on segment operating profit. NewMarket Services expenses are charged to each subsidiary pursuant to services agreements between the companies. Depreciation on segment property, plant, and equipment, as well as amortization of segment intangible assets and lease right-of-use assets, is included in segment operating profit.

The table below reports segment operating profit for the last three years. A reconciliation of segment operating profit to income before income tax expense is in Note 4.

Petroleum Additives - Petroleum additives segment operating profit decreased $26 million when comparing 2020 to 2019. Both periods included the impact of the same factors that affected gross profit (see discussion below) including an unfavorable foreign currency translation impact.

The operating profit margin was 16.7% in 2020 and 16.5% in 2019. Despite the economic disruption from the COVID-19 pandemic during 2020 resulting in lower product shipment volumes and reduced net sales compared to 2019, the operating profit margin is slightly improved from 2019 levels. Operating profit margins remain a priority, and while they will fluctuate from quarter to quarter due to multiple factors, we believe the fundamentals of our business and industry are unchanged.

Petroleum additives gross profit decreased $37 million when comparing 2020 and 2019. Cost of goods sold as a percentage of net sales was 70.4% in 2020 and 71.1% in 2019.

When comparing 2020 and 2019, the decrease in gross profit resulted from unfavorable impacts from product shipments and lower selling prices (both as discussed in the Net Sales section above), as well as unfavorable conversion costs, which together contributed over 100% of the change between 2020 and 2019. These unfavorable factors were partially offset by lower raw material costs.

Petroleum additives selling, general, and administrative expenses (SG&A) were $7 million, or 5.7% lower in 2020 compared to 2019. SG&A as a percentage of net sales was 5.9% in 2020 and 5.8% in 2019. Our SG&A costs are primarily personnel-related and include salaries, benefits and other costs associated with our workforce, including travel-related expenses. While personnel-related costs fluctuate from year to year, there were no significant changes in the drivers of these costs when comparing 2020 and 2019 other than reduced travel-related expenses due to the impact of the COVID-19 pandemic.

Our investment in petroleum additives research, development, and testing (R&D) decreased approximately $4 million when comparing 2020 with 2019. As a percentage of net sales, R&D was 7.0% in 2020 and 6.6% in 2019. Our R&D investments reflect our efforts to support the development of solutions that meet our customers' needs, meet new and evolving standards, and support our expansion into new product areas. Our approach to R&D investment, as it is with SG&A, is one of purposeful spending on programs to support our current product base and to ensure that we develop products to support our customers' programs in the future. R&D investments include personnel-related costs, as well as costs for internal and external testing of our products. Substantially all investments in new product development are incurred in the United States and the U.K., with approximately 70% of total R&D being attributable to the North America and EMEAI regions. The remaining R&D is attributable to the Asia Pacific and Latin America regions and represents customer technology support services in those regions. All of our R&D is related to the petroleum additives segment.

The following discussion references certain captions on the Consolidated Statements of Income.

Interest and Financing Expenses

Interest and financing expenses were $26 million in 2020 and $29 million in 2019. The decrease in interest and financing expense between 2020 and 2019 resulted primarily from a lower average interest rate during 2020.

Other Income (Expense), Net

Other income (expense), net was income of $46 million in 2020 and $24 million in 2019. The amount for 2020 included a gain of $16 million related to the sale of a non-operating parcel of real estate. The amounts for both periods also included the components of net periodic benefit cost (income), except for service costs. See Note 17 for further information on total periodic benefit cost (income).

Table of Contents

Income Tax Expense

Income tax expense was $61 million in 2020 and $77 million in 2019. The effective tax rate was 18.3% in 2020 and 23.3% in 2019. When comparing 2020 and 2019, income tax decreased $16 million due to the lower effective tax rate. The decrease in the effective tax rate was primarily the result of finalizing prior year tax filings and releasing certain tax reserves.

CASH FLOWS DISCUSSION

We generated cash from operating activities of $284 million in 2020 and $337 million in 2019.

During 2020, we used the $284 million of cash generated from operations along with $19 million of cash on hand to repurchase $101 million of our common stock, pay $83 million of dividends on our common stock, repay $45 million on our revolving credit facility, and fund $93 million for capital expenditures. Cash flows from operating activities included a decrease of $54 million from higher working capital requirements, cash contributions of $11 million to our pension and postretirement plans, and a gain of $16 million related to the sale of a parcel of non-operating real estate.

During 2019, we used the $337 million cash generated from operations to repay $123 million on our revolving credit facility, pay $82 million of dividends on our common stock, and fund capital expenditures of $59 million. Cash flows from operating activities included an increase of $5 million from lower working capital requirements, as well as cash contributions of $10 million to our pension and postretirement plans.

FINANCIAL POSITION AND LIQUIDITY

Cash

At December 31, 2020, we had cash and cash equivalents of $125 million as compared to $144 million at the end of 2019.

Cash and cash equivalents held by our foreign subsidiaries amounted to approximately $97 million at December 31, 2020 and $99 million at December 31, 2019. Periodically, we repatriate cash from our foreign subsidiaries to the United States through intercompany dividends and loans. We do not anticipate significant tax consequences of future distributions of foreign earnings.

A portion of our foreign cash balances is associated with earnings that we have asserted are indefinitely reinvested. We plan to use these indefinitely reinvested earnings to support growth outside of the United States through funding of operating expenses, research and development expenses, capital expenditures, and other cash needs of our foreign subsidiaries.

Debt

A summary of our debt instruments follows. A full discussion is in Note 13.

4.10% Senior Notes - At both December 31, 2020 and December 31, 2019, we had $350 million of 4.10% senior notes due 2022 with interest payable semiannually and which are senior unsecured obligations. We were in compliance with all covenants under the indenture governing the 4.10% senior notes as of December 31, 2020 and December 31, 2019.

3.78% Senior Notes - On January 4, 2017, we issued $250 million in senior unsecured notes in a private placement with The Prudential Insurance Company of America and certain other purchasers. These notes bear interest at 3.78% and mature on January 4, 2029. Interest is payable semiannually. Principal payments of $50 million are payable annually beginning on January 4, 2025. We have the right to make optional prepayments on the notes at any time, subject to certain limitations. We were in compliance with all covenants under the 3.78% senior notes as of December 31, 2020 and December 31, 2019.

Table of Contents

Revolving Credit Facility – On March 5, 2020, NewMarket and certain foreign subsidiary borrowers entered into a Credit Agreement (the Credit Agreement) with a term of five years. The Credit Agreement provides for a $900 million, multicurrency revolving credit facility with a $500 million sublimit for foreign currency borrowings, a $50 million sublimit for letters of credit, and a $20 million sublimit for swingline loans. The Credit Agreement includes an expansion feature which allows us, subject to certain conditions, to request an increase in the aggregate amount of the revolving credit facility or obtain incremental term loans in an amount up to $425 million. NewMarket's obligations under the Credit Agreement are unsecured and the obligations of foreign subsidiary borrowers are fully and unconditionally guaranteed by NewMarket. The revolving credit facility is available on a revolving basis until March 5, 2025.

There were no outstanding borrowings under the revolving credit facility at December 31, 2020 compared to $45 million in outstanding borrowings at December 31, 2019 under our former facility. Outstanding letters of credit amounted to $2 million at December 31, 2020 and $3 million at December 31, 2019 resulting in the unused portion of the applicable credit facility amounting to $898 million at December 31, 2020 and $803 million at December 31, 2019.

The average interest rate for borrowings under the credit facilities was 1.4% during 2020 and 3.0% during 2019.

The Credit Agreement contains financial covenants that require NewMarket to maintain a consolidated Leverage Ratio (as defined in the Credit Agreement) of no more than 3.75 to 1.00 except during an Increased Leverage Period (as defined in the Credit Agreement). At December 31, 2020, the Leverage Ratio was 1.45. We were in compliance with all covenants under the revolving credit facility in effect at December 31, 2020 and at December 31, 2019.

Other Borrowings - Two of our subsidiaries in Singapore and China each have access to separate short-term lines of credit of $10 million. One of our subsidiaries in the U.K. has access to a short-term line of credit of 10 million Euro. There was no activity on these lines of credit in 2020, nor was there an outstanding balance on any of these lines of credit at December 31, 2019.

***

We had long-term debt of $599 million at December 31, 2020 and $643 million at December 31, 2019. The decrease in debt resulted from repaying borrowings outstanding under the revolving credit facility during 2020.

As a percentage of total capitalization (total long-term debt and shareholders’ equity), our total long-term debt decreased from 48.5% at the end of 2019 to 44.1% at the end of 2020. The change in the percentage was primarily the result of the decrease in long-term debt, as well as the increase in shareholders' equity. The change in shareholders’ equity primarily reflects our earnings and the impact of the foreign currency translation adjustment offset by stock repurchases, dividend payments, and a decrease in the funded position of our defined benefit plans. Normally, we repay any outstanding long-term debt with cash from operations or refinancing activities.

Working Capital

Including cash and cash equivalents and the impact of foreign currency on the balance sheet, at December 31, 2020, we had working capital of $586 million, resulting in a current ratio of 2.87 to 1. Our working capital at December 31, 2019 on the same basis was $571 million, resulting in a current ratio of 2.85 to 1.

Other than the decrease in cash and cash equivalents, the most significant changes in working capital since December 31, 2019 resulted from an increase in inventory, which was partially offset by an increase in accounts payable. The increase in inventories was primarily due to a reduction in an inventory reserve, as well as planning for first quarter 2021 sales forecasts. The increase in accounts payable reflected normal fluctuations across the regions.

Capital Expenditures

Capital expenditures were $93 million for 2020 and $59 million for 2019. We currently estimate capital expenditures in 2021 will be in the range of $75 million to $85 million as we anticipate spending on several improvements to our manufacturing and R&D infrastructure around the world. We expect to continue to finance capital spending through cash on hand and cash provided from operations, together with borrowing available under our $900 million revolving credit facility.

Table of Contents

Environmental Expenses

We spent approximately $29 million in both 2020 and in 2019 for ongoing environmental operating and clean-up costs, excluding depreciation of previously capitalized expenditures. These environmental operating and clean-up expenses are included in cost of goods sold. We expect to continue to fund these costs through cash provided by operations.

Liquidity and Contractual Obligations

We have both current and long-term obligations that have known payment streams and are discussed throughout this Report on Form 10-K. The more material of these include debt-related obligations, lease obligations, purchase commitments, including those for property, plant, and equipment, contributions to pension and postretirement benefit plans, and environmental dismantling and decontamination.

The debt-related contractual obligations include both principle payments on outstanding long-term debt and the related interest payments. The maturity dates and interest rates, as well as information on the repayment of the principle on our long-term debt is detailed above in the Debt section, as well as in Note 13. At December 31, 2020, all of our long-term debt was at fixed rates. Interest is paid semi-annually on both of our fixed rate long-term debt agreements.

Note 16 provides information by year on our lease obligations which have commenced. We also have obligations for leases that have not yet commenced of $5 million in 2021, $3 million in 2022, $3 million in 2023, $2 million in 2024, $2 million in 2025, and $10 million thereafter. Note 17 includes information on contributions to pension and postretirement benefit plans. Benefit payments under these plans are included in Note 17 are predominantly paid from assets held in trust. Further information on purchase commitments, including those for purchases of property, plant, and equipment are in Note 20.

The annual operating expenses and capital expenditures associated with compliance with environmental, health, and safety regulations are included in Item 1, Governmental and Environmental Regulations. In addition to these costs, there are expected cash flows for dismantling and decontamination of environmental sites. At December 31, 2020, these costs were estimated at $1 million in each of 2021 through 2025, and $8 million thereafter.

We expect that cash from operations, together with borrowing available under our credit facilities, will continue to be sufficient for our operating needs and planned capital expenditures for both a current and long-term horizon.

The table below shows our contractual obligations at December 31, 2020 by year due.

Pension and Postretirement Benefit Plans

Our U.S. and foreign benefit plans are discussed separately below. The information applies to all of our U.S. benefit plans. Our foreign plans are quite diverse, and the actuarial assumptions used by the various foreign plans are based upon the circumstances of each particular country and retirement plan. We use a December 31 measurement date to determine our pension and postretirement expenses and related financial disclosure information. Additional information on our pension and postretirement plans is in Note 17.

U.S. Pension and Postretirement Benefit Plans—The average remaining service period of active participants for our U.S. plans is 13 years, while the average remaining life expectancy of inactive participants is 23 years. We utilize the sex distinct Pri-2012 table with separate rates for annuitants, non-annuitants, and contingent annuitants, projected generationally using Scale MP-2020 in determining the impact of the U.S. benefit plans on our financial statements.

Investment Return Assumptions and Asset Allocation—We periodically review our assumptions for the long-term expected return on pension plan assets. As part of the review and to develop expected rates of return, we considered an analysis of expected returns based on the U.S. plans’ asset allocation as of both January 1, 2021 and January 1, 2020. This analysis reflects our expected long-term rates of return for each significant asset class or economic indicator. The range of returns developed relies both on forecasts and on broad-market historical benchmarks for expected return, correlation, and volatility for each asset class. While the asset allocation for our U.S. pension plans is predominantly weighted toward equities, through the ongoing monitoring of our investments and review of market data, we have determined that we should reduce the expected long-term rate of return for our U.S. pension plans from 8.5% to 8.0% at December 31, 2020.

An actuarial gain on the assets occurred during both 2020 and 2019 as the actual investment return for all of our U.S. pension plans exceeded the expected return by approximately $43 million in 2020 and $75 million in 2019. Investment gains and losses are recognized in earnings on an amortized basis over a period of years. The amortization of the actuarial net loss is expected to be approximately $6 million in 2021 resulting primarily from the actuarial loss on the plan liabilities which has only partially been offset by the investment gains on plan assets. We expect that there will be continued volatility in pension expense as actual investment returns vary from the expected return, but we continue to believe the potential long-term benefits justify the risk premium for equity investments.

At December 31, 2020, our expected long-term rate of return on our postretirement plans was 4.5%. This rate varies from the pension rate of 8.0% primarily because of the difference in investment of assets. The assets of the postretirement plan are held in an insurance contract, which results in a lower assumed rate of investment return.

Pension expense and the life insurance portion of postretirement expense are sensitive to changes in the expected return on assets. For example, decreasing the expected rate of return by 100 basis points to 7.0% for pension assets and 3.5% for postretirement benefit assets (while holding other assumptions constant) would increase the forecasted 2021 expense for our U.S. pension and postretirement plans by approximately $5 million. Similarly, a 100 basis point increase in the expected rate of return to 9.0% for pension assets and 5.5% for postretirement benefit assets (while holding other assumptions constant) would reduce forecasted 2021 pension and postretirement expense by $5 million.

Table of Contents

Discount Rate Assumption—We develop the discount rate assumption by determining the single effective discount rate for a unique hypothetical portfolio constructed from investment-grade bonds that, in the aggregate, match the projected cash flows of each of our retirement plans. The discount rate is developed based on the hypothetical portfolio on the last day of December. The discount rate at December 31, 2020 was 2.875% for all plans.

Pension and postretirement benefit expense is also sensitive to changes in the discount rate. For example, decreasing the discount rate by 100 basis points to 1.875% (while holding other assumptions constant) would increase the forecasted 2021 expense for our U.S. pension and postretirement benefit plans by approximately $9 million. A 100 basis point increase in the discount rate to 3.875% would reduce forecasted 2021 pension and postretirement benefit expense by $7 million.

Rate of Projected Compensation Increase—We have maintained our rate of projected compensation increase at December 31, 2020 at 3.5%. The rate assumption was based on an analysis of our projected compensation increases for the foreseeable future.

Liquidity—Cash contribution requirements to the pension plan are sensitive to changes in assumed interest rates and investment gains or losses in the same manner as pension expense. We expect our aggregate cash contributions to the U.S. pension plans will be approximately $3 million in 2021. We expect our contributions to the postretirement benefit plans will be approximately $2 million in 2021.

Foreign Pension Benefit Plans—Our foreign pension plans are quite diverse. The following information applies only to our U.K. pension plan, which represents the majority of the amounts recorded in our financial statements for our foreign pension plans. The average remaining service period of active participants for our U.K. plan is 16 years, while the average remaining life expectancy of inactive participants is 26 years. In determining the impact of the U.K. pension plans on our financial statements, we utilize the S3P (Light) mortality tables and allow for future projected improvements in life expectancy in line with the CMI 2019 model (with the core smoothing parameter and an initial addition to mortality improvements of 0.4% per year) with a long-term rate of improvement of 1% per year based on the membership of the plan.

Investment Return Assumptions and Asset Allocation—We periodically review our assumptions for the long-term expected return on the U.K. pension plan assets. The expected long-term rate of return is based on both the asset allocation, as well as yields available in the U.K. markets.

The target asset allocation in the U.K. is to be invested 40% in pooled equities funds, 40% in pooled government bonds, and 20% in pooled diversified growth funds. The actual allocation at the end of 2020 was 40% in pooled equities funds, 40% in pooled government bonds, and 20% in pooled diversified growth funds. Based on the actual asset allocation and the expected yields available in the U.K. markets, the expected long-term rate of return for the U.K. pension plan was 5.0% at December 31, 2020.

Actuarial gains on the assets occurred during both 2020 and 2019 as the actual investment return exceeded the expected investment return by approximately $4 million in 2020 and $10 million in 2019. Investment gains and losses are recognized in earnings on an amortized basis over a period of years. The amortization of the actuarial net loss is expected to be approximately $3 million in 2021 resulting primarily from the actuarial loss on the plan liabilities, which has only partially been offset by investment gains on the plan assets. We expect that there will be continued volatility in pension expense as actual investment returns vary from the expected return, but we continue to believe the potential benefits justify the risk premium for the target asset allocation.

Pension expense is sensitive to changes in the expected return on assets. For example, decreasing the expected rate of return by 100 basis points to 4% (while holding other assumptions constant) would increase the forecasted 2021 expense for our U.K. pension plan by approximately $2 million. Similarly, a 100 basis point increase in the expected rate of return to 6% (while holding other assumptions constant) would reduce forecasted 2021 pension expense by approximately $2 million.

Discount Rate Assumption—We utilize a yield curve based on AA-rated corporate bond yields in developing a discount rate assumption. The yield appropriate to the duration of the U.K. plan liabilities is then used. The discount rate at December 31, 2020 was 1.3%.

Table of Contents

Pension expense is also sensitive to changes in the discount rate. For example, decreasing the discount rate by 100 basis points to 0.3% (while holding other assumptions constant) would increase the forecasted 2021 expense for our U.K. pension plans by approximately $2 million. A 100 basis point increase in the discount rate to 2.3% would reduce forecasted 2021 pension expense by approximately $1 million.

Rate of Projected Compensation Increase—Our rate of projected compensation increase at December 31, 2020 is 4.1%. The rate assumption was based on an analysis of our projected compensation increases for the foreseeable future.

Liquidity—Cash contribution requirements to the U.K. pension plan are sensitive to changes in assumed interest rates and investment gains or losses. We expect our aggregate U.K. cash contributions will be approximately $5 million in 2021.

OUTLOOK

Our stated goal is to provide a 10% compounded return per year for our shareholders over any five-year period (defined by earnings per share growth plus dividend yield), although we may not necessarily achieve a 10% return each year. We continue to have confidence in our customer-focused strategy and approach to the market. We believe the fundamentals of how we run our business - a long-term view, safety-first culture, customer-focused solutions, technology-driven product offerings, and world-class supply chain capability - will continue to be beneficial for all of our stakeholders over the long term.

We expect our petroleum additives segment will continue to experience impacts to its operating performance due to the current economic environment. Our global business will see varying effects on demand that will differ by region based on our product portfolio and geographic coverage. The global market should stabilize when government restrictions on the movement of people, goods, and services implemented as a result of the COVID-19 pandemic are lifted, as modern transportation and machinery cannot function without our products. We expect that the petroleum additives market will grow in the 1% to 2% range annually for the foreseeable future. We plan to exceed that growth rate over the long-term.

In the past several years we have made significant investments in our business as the industry fundamentals remain positive. These investments have been and will continue to be in organizational talent, technology development and processes, and global infrastructure, consisting of technical centers, production capability and geographic expansion. We intend to utilize these investments to improve our ability to deliver the solutions that our customers value, expand our global reach, and enhance our operating results. We will continue to invest in our capabilities to provide even better value, service, technology, and customer solutions.

Typically, our business generates significant amounts of cash beyond what is necessary for the expansion and growth of our current offerings. We regularly review our many internal opportunities to utilize excess cash from technological, geographic, production capability, and product line perspectives. We believe our capital spending is creating the capability we need to grow and support our customers worldwide, and our research and development investments are positioning us well to provide added value to our customers. Our primary focus in the acquisition area remains on the petroleum additives industry. It is our view that this industry segment will provide the greatest opportunity for solid returns on our investments while minimizing risk. We remain focused on this strategy and will evaluate any future opportunities. We will continue to evaluate all alternative uses of cash to enhance shareholder value, including stock repurchases and dividends.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The following discussion highlights some of the more critical areas where a significant change in facts and circumstances in our operating and financial environment could cause a change in future reported financial results.

Income Taxes

We file United States, foreign, state, and local income tax returns. Significant judgment is required in determining our worldwide provision for income taxes and recording the related tax assets and liabilities. Any significant impact as a result of changes in underlying facts, law, tax rates, or tax audits could lead to adjustments to our income tax expense, effective tax rate, financial position, or cash flow.

Table of Contents

Deferred income taxes are provided for the estimated income tax effect of temporary differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities, as well as for net operating losses and tax credit carryforwards. When recording these deferred tax assets and liabilities, we must estimate the tax rates we expect will apply to taxable income in the periods in which the deferred tax liability or asset is expected to be settled or realized. In addition, we may record valuation allowances to reduce deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. Judgment is required as we consider the scheduled reversal of deferred tax assets and liabilities, projected future taxable income, and tax planning strategies in making this assessment. If our estimates and assumptions change from those used when we recorded deferred tax assets and liabilities, the effect on our results of operations and financial position could be material.

The income tax returns for our entities in the United States and in foreign jurisdictions are open for examination by tax authorities. We assess our income tax positions and record a liability for all years open for examination based upon our evaluation of the facts, circumstances, and information available at the reporting date. The economic benefit associated with a tax position will be recognized only if we determine it is more likely than not to be upheld on audit. Although we believe our estimates and judgments are reasonable, actual results could differ, resulting in gains or losses that may be material to our results of operations and financial position.

At each interim reporting period, we estimate an effective income tax rate that is expected to be applicable for the full year. Our provision for income taxes is impacted by the income tax rates of the countries where we operate. A change in the geographical source of our income can affect the effective tax rate. Significant judgment is involved regarding the application of global income tax laws and regulations when projecting the jurisdictional mix of income. Additionally, interpretations of tax laws, court decisions, or other guidance provided by taxing authorities influence our estimate of the effective income tax rate. As a result, our actual effective income tax rate and related income tax liabilities may differ materially from our estimated effective tax rate and related income tax liabilities.

Intangibles (net of amortization) and Goodwill

We have certain identifiable intangibles amounting to $6 million and goodwill amounting to $124 million at December 31, 2020 that are discussed in Note 10. These intangibles and goodwill relate to our petroleum additives business. The intangibles are being amortized over periods with up to approximately 8 years of remaining life. We continue to assess the market related to the intangibles and goodwill, as well as their specific values and evaluate the intangibles and goodwill for any potential impairment when significant events or circumstances occur that might impair the value of these assets. We have concluded the values are appropriate, as are the amortization periods for the intangibles. However, if conditions were to substantially deteriorate in the petroleum additives market, it could possibly cause a decrease in the estimated useful lives of the intangible assets or result in a noncash write-off of all or a portion of the intangibles and goodwill carrying amounts. A reduction in the amortization period of the intangibles would have no effect on cash flows. We do not anticipate such a change in the market conditions in the near term.

Pension Plans and Other Postretirement Benefits

We use assumptions to record the impact of the pension and postretirement benefit plans in the financial statements. These assumptions include the discount rate and the expected long-term rate of return on plan assets. A change in any of these assumptions could cause different results for the plans and therefore, impact our results of operations, cash flows, and financial condition. We develop these assumptions after considering available information that we deem relevant. Information is provided on the pension and postretirement plans in Note 17. In addition, further disclosure of the effect of changes in these assumptions is provided in the “Financial Position and Liquidity” section of Item 7.

Environmental and Legal Proceedings

We have disclosed our environmental matters in Item 1 of this Annual Report on Form 10-K, as well as in Note 20. Our estimates for costs that will be incurred to satisfy our obligations related to environmental matters are affected by many variables, including our judgment regarding the extent of remediation that will be required, future changes in and enforcement and interpretation of laws and regulations, current and future technology available, and timing of remediation activities. While we currently do not anticipate significant changes to the many factors that could impact our environmental requirements, we continue to keep our accruals consistent with these requirements as they change.

Table of Contents

Also, as noted in the discussion of “Legal Proceedings” in Item 3 of this Annual Report on Form 10-K, while it is not possible to predict or determine with certainty the outcome of any legal proceeding, it is our opinion, based on our current knowledge, that we will not experience any material adverse effects on our results of operations, cash flows, or financial condition as a result of any pending or threatened proceeding.

RECENTLY ISSUED ACCOUNTING STANDARDS

For a full discussion of the more significant recently issued accounting standards, see Note 23.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to many market risk factors, including fluctuations in interest and foreign currency rates, as well as changes in the cost of raw materials. These risk factors may affect our results of operations, cash flows, and financial position.

We manage these risks through regular operating and financing methods, including the use of derivative financial instruments. When we have derivative instruments, they are with major financial institutions and are not for speculative or trading purposes. Also, as part of our financial risk management, we regularly review significant contracts for embedded derivatives and, if identified, would record them in accordance with accounting principles generally accepted in the United States.

The following analysis presents the effect on our results of operations, cash flows, and financial position as if the hypothetical changes in market risk factors occurred at December 31, 2020. We analyzed only the potential impacts of our hypothetical assumptions. This analysis does not consider other possible effects that could impact our business.

Interest Rate Risk

At December 31, 2020, we had total long-term debt of $599 million. All of the long-term debt is at fixed rates. There was no interest rate risk at the end of the year associated with the fixed rate debt.

At December 31, 2020, we had no outstanding variable rate debt under our revolving credit facility. Therefore, we had no interest rate risk at the end of the year associated with the variable rate debt.

A hypothetical 100 basis point decrease in interest rates, holding all other variables constant, would have resulted in a change of $22 million in fair value of our debt at December 31, 2020.

Foreign Currency Risk

We sell to customers in foreign markets through our foreign subsidiaries, as well as through export sales from the United States. These transactions are often denominated in currencies other than the U.S. Dollar. Our primary currency exposures are the European Union Euro, British Pound Sterling, Japanese Yen, Chinese Renminbi, Indian Rupee, Singapore Dollar, Mexican Peso, Australian Dollar, and Canadian Dollar. We may enter into forward contracts as hedges to minimize the fluctuation of intercompany accounts receivable denominated in foreign currencies. At December 31, 2020, we had no outstanding forward contracts.

Raw Material Price Risk

We utilize a variety of raw materials in the manufacture of our products, including base oil, polyisobutylene, antioxidants, alcohols, solvents, sulfonates, friction modifiers, olefins, and copolymers. We may also enter into contracts which commit us to purchase some of our more critical raw materials based on anticipated demand. Our profitability is sensitive to changes in the quantities of raw materials we may need and the costs of those materials which may be caused by changes in supply, demand or other market conditions, over which we have little or no control. In addition, political and economic conditions in certain regions of the world in which we operate have caused, and may continue to cause, our demand for and the cost of our raw materials to fluctuate. War, armed hostilities, terrorist acts, civil unrest, or other incidents may also cause a sudden or sharp change in our demand for and the cost of our raw materials. If we experience such increases in the cost of our raw materials, we may not be able to pass them along to our customers in the form of price increases for our products. The inability to do so would have a negative impact on our operating profit. In

Table of Contents

addition, if our demand for raw materials were to decline such that we would not have need for the quantities required to be purchased under commitment agreements, we could incur additional charges that would affect our profitability.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of NewMarket Corporation

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of NewMarket Corporation and its subsidiaries (the “Company”) as of December 31, 2020 and 2019, and the related consolidated statements of income, of comprehensive income, of shareholders' equity and of cash flows for each of the three years in the period ended December 31, 2020, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies

Table of Contents

and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Valuation of Pension Benefit Obligation

As described in Note 17 to the consolidated financial statements, the Company’s consolidated pension benefit obligation, excluding other postretirement benefits, was $720 million as of December 31, 2020. Management develops the actuarial assumptions used by the various US and foreign plans based upon the circumstances of each particular country and pension plan. As disclosed by management, the determination of the pension benefit obligation requires the use of estimates and assumptions. Management’s assumption in the determination of the pension benefit obligation is the discount rate.

The principal considerations for our determination that performing procedures relating to the valuation of the pension benefit obligation is a critical audit matter are the significant judgment by management to determine the pension benefit obligation. This in turn led to a high degree of auditor judgment, subjectivity, and effort in performing procedures to evaluate management’s significant assumption used in the valuation of the pension benefit obligation, specifically the discount rate. In addition, the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the valuation of the pension benefit obligation, including controls over the Company’s methods, significant assumption, and data. These procedures also included, among others, testing the completeness, accuracy, and relevance

of underlying data used in the valuation of the pension benefit obligation. With the involvement of professionals with specialized skill and knowledge to assist, these procedures also included testing management’s process for determining the pension benefit obligation, evaluating the appropriateness of the methods, and evaluating the reasonableness of the significant assumption, specifically the discount rate.

Notes to Consolidated Financial Statements

1. Summary of Significant Accounting Policies

Consolidation—Our consolidated financial statements include the accounts of NewMarket Corporation and its subsidiaries. All intercompany transactions are eliminated upon consolidation. References to "we," "us," "our," the "company," and "NewMarket" are to NewMarket Corporation and its consolidated subsidiaries, unless the context indicates otherwise.

NewMarket is the parent company of separate operating companies, each managing its own assets and liabilities. Those companies are Afton, which focuses on petroleum additive products; Ethyl, representing certain contracted manufacturing and services, as well as the antiknock compounds business; and NewMarket Development, which manages the real property and improvements that we own in Virginia. NewMarket is also the parent company of NewMarket Services, which provides various administrative services to NewMarket, Afton, Ethyl, and NewMarket Development.

Certain reclassifications have been made to the accompanying consolidated financial statements and the related notes to conform to the current presentation.

Foreign Currency Translation—We translate the balance sheets of our foreign subsidiaries into U.S. Dollars based on the current exchange rate at the end of each period. We translate the statements of income using the weighted-average exchange rates for the period. NewMarket includes translation adjustments in the Consolidated Balance Sheets as part of accumulated other comprehensive loss and transaction adjustments in the Consolidated Statements of Income as part of cost of goods sold. Foreign currency transaction adjustments resulted in a net loss of $3 million in 2020, $4 million in 2019, and $8 million 2018.

Revenue Recognition—We recognize revenue when control of the product is transferred to our customer and for an amount that reflects the consideration we expect to collect from the customer. Net sales (revenues) are reported at the gross amount billed, including amounts related to shipping that are charged to the customer. Provisions for rebates to customers are recorded in the same period that the related sales are recorded. Freight costs incurred on the delivery of products are included in the Consolidated Statements of Income in cost of goods sold. Our standard terms of delivery are included in our contracts, sales order confirmation documents, and invoices. Taxes assessed by a governmental authority concurrent with sales to our customers, including sales, use, value-added, and revenue-related excise taxes, are not included as net sales, but are reflected in accrued expenses until remitted to the appropriate governmental authority.

Cash and Cash Equivalents—Our cash equivalents consist of government obligations and commercial paper with original maturities of 90 days or less. Throughout the year, we have cash balances in excess of federally insured amounts on deposit with various financial institutions. We state cash and cash equivalents at cost, which approximates fair value.

Accounts Receivable—We record our accounts receivable at outstanding principal adjusted for allowances for credit losses. The allowance for credit losses represents probable losses to be incurred if our customers do not make required payments. We determine the adequacy of the allowance by periodically evaluating each customer’s receivable balance, considering their financial condition and credit history, and considering current economic conditions. The allowance for credit losses was not material at December 31, 2020 or December 31, 2019.

Inventories—NewMarket values its inventories at the lower of cost or net realizable value. In the United States, petroleum additives inventory cost is determined on the last-in, first-out (LIFO) basis. For all other inventory, we determine cost using a weighted-average method. Inventory cost includes raw materials, direct labor, and manufacturing overhead.

Property, Plant, and Equipment—We state property, plant, and equipment at cost less accumulated depreciation and compute depreciation by the straight-line method based on the estimated useful lives of the assets. We capitalize expenditures for significant improvements that extend the useful life of the related property. We expense repairs and maintenance, including plant turnaround costs, as incurred. When property is sold or retired, we remove the cost and accumulated depreciation from the accounts and any related gain or loss is included in earnings.

Notes to Consolidated Financial Statements

Intangibles (Net of Amortization) and Goodwill—Identifiable intangibles include the cost of acquired contracts, formulas and technology, trademarks and trade names, and customer bases. We assign a value to identifiable intangibles based on independent third-party appraisals and management's assessment at the time of acquisition. NewMarket amortizes the cost of the customer bases by an accelerated method and the cost of the remaining identifiable intangibles by the straight-line method over the estimated economic life of the intangible.

Goodwill arises from the excess of cost over the net assets of businesses acquired. Goodwill represents the residual purchase price after allocation to all identifiable net assets. We test goodwill for impairment each year, as well as whenever a significant event or circumstance occurs which could reduce the fair value of the reporting unit to which the goodwill applies below the carrying amount of the reporting unit.

Impairment of Long-Lived Assets—When significant events or circumstances occur that might impair the value of long-lived assets, we evaluate recoverability of the recorded cost of these assets. Assets are considered to be impaired if their carrying amount is not recoverable from the estimated undiscounted future cash flows associated with the assets. If we determine an asset is impaired and its recorded cost is higher than estimated fair market value based on the estimated present value of future cash flows, we adjust the asset to estimated fair market value.

Environmental Costs—NewMarket capitalizes environmental compliance costs if they extend the useful life of the related property or prevent future contamination. Environmental compliance costs also include maintenance and operation of pollution prevention and control facilities. We expense these compliance costs in cost of goods sold as incurred.

Accrued environmental remediation and monitoring costs relate to an existing condition caused by past operations. NewMarket accrues these costs in current operations within cost of goods sold in the Consolidated Statements of Income when it is probable that we have incurred a liability and the amount can be reasonably estimated. These estimates are based on an assessment of the site, available clean-up methods, and prior experience in handling remediation.

When we can reliably determine the amount and timing of future cash flows, we discount these liabilities, incorporating an inflation factor.

Legal Costs—We expense legal costs in the period incurred.

Employee Savings Plan—Most of our full-time salaried and hourly employees may participate in defined contribution savings plans. Employees who are covered by collective bargaining agreements may also participate in a savings plan according to the terms of their bargaining agreements. Employees, as well as NewMarket, contribute to the plans. We made contributions of $7 million in 2020, and $6 million in both 2019 and 2018 related to these plans.

Research, Development, and Testing Expenses—NewMarket expenses all research, development, and testing costs as incurred. R&D costs include personnel-related costs, as well as internal and external testing of our products.

Income Taxes—We recognize deferred income taxes for temporary differences between the financial reporting basis and the income tax basis of assets and liabilities. We also adjust for changes in tax rates and laws at the time the changes are enacted. A valuation allowance is recorded when it is more likely than not that a deferred tax asset will not be realized. We typically remove a tax impact from accumulated other comprehensive loss when the underlying circumstance which gave rise to the tax impact no longer exists. We recognize accrued interest and penalties associated with uncertain tax positions as part of income tax expense on our Consolidated Statements of Income.

Leases—We determine if an arrangement includes a lease at the inception of the agreement. The right-of-use asset and lease liability are determined at the lease commencement date and are based on the present value of estimated lease payments.

Our lease agreements contain both fixed and variable lease payments. In some cases, variable lease payments are based on a rate or an index. Fixed lease payments, as well as variable lease payments which are based on a rate or index, are included in the determination of the right-of-use asset and lease liability. Variable lease payments that are not based on a rate or index are expensed when incurred.

The present value of estimated lease payments is determined utilizing the rate implicit in the lease agreement, if that rate can be determined. If the implicit rate cannot be determined, the present value of estimated lease payments is determined

Notes to Consolidated Financial Statements

utilizing our incremental borrowing rate. The incremental borrowing rate is determined at the lease commencement date and is developed utilizing a readily available market interest rate curve adjusted for our credit quality.

Some of our leases include an option to renew that can extend the lease term. For those leases which are reasonably certain to be renewed, we include the renewal in the lease term.

We do not recognize leases with terms of 12 months or less on the balance sheet for any lease class, except the railcar lease class. For the short-term leases not recorded on the balance sheet, the lease payments are recognized in the consolidated statements of income on a straight-line basis over the lease term.

We account for the lease and nonlease components as a single lease component in determining the right-of-use assets and lease liabilities for all lease classes.

Derivative Financial Instruments and Hedging Activities—We are exposed to certain risks arising from both our business operations and economic conditions. We manage our exposures to a wide variety of business and operational risks through management of our core business activities.

We manage certain economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of our debt funding, as well as through the use of derivative financial instruments. We sometimes enter into interest rate swaps to manage our exposure to interest rate movements.

In addition, our foreign operations expose us to fluctuations of foreign exchange rates. These fluctuations may impact our results of operations, financial position, and cash flows. To manage this exposure, we sometimes enter into foreign currency forward contracts to minimize currency exposure due to cash flows from foreign operations.

We record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. We may enter into derivative contracts that are intended to economically hedge certain of our risks, even though hedge accounting does not apply or we elect not to apply hedge accounting. We do not enter into derivative instruments for speculative purposes. We had no derivative financial instruments outstanding at December 31, 2020 or December 31, 2019.

Stock-based Compensation—We calculate the fair value of restricted stock and restricted stock units based on the closing price of our common stock on the date of grant. If award recipients are entitled to receive dividends during the vesting period, we make no adjustment to the fair value of the award for dividends. If the award does not entitle recipients to dividends during the vesting period, we reduce the grant-date price of our common stock by the present value of the dividends expected to be paid on the underlying shares during the vesting period, discounted at the risk-free interest rate.

We recognize stock-based compensation expense for the number of awards expected to vest on a straight-line basis over the requisite service period.

Estimates and Risks Due to Concentration of Business—The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

In addition, our financial results can be influenced by certain risk factors. Some of our significant concentrations of risk include the following:

•reliance on a small number of significant customers;

•customers concentrated in the fuel and lubricant industries; and

•production of several of our products solely at one facility.

2. Net Sales

Our revenues are primarily derived from the manufacture and sale of petroleum additives products. We sell petroleum additives products across the world including to customers located in our North America, Latin America, Asia Pacific, and EMEAI regions. Our customers primarily consist of global, national, and independent oil companies. While some of our customers have payment terms beyond 30 days, we do not provide extended payment terms of a year or more, nor do our contracts include a financing component. Our allowance for credit losses is immaterial, as are any bad debts we incur. In limited cases, we collect funds in advance of shipping product to our customers and recognizing the related revenue. These prepayments from customers are recorded as a contract liability to our customer until we recognize the revenue. Prepayments from our customers totaled $1 million in both December 31, 2020 and December 31, 2019. Revenue recognized from funds collected in advance from customers in an earlier period was $1 million in both 2020 and 2019 and $3 million in 2018.

We recognize revenue when control of the product is transferred to our customer and for an amount that reflects the consideration we expect to collect from the customer. Control is generally transferred to the customer when title transfers (which may include physical possession by the customer), we have a right to payment from the customer, the customer has accepted the product, and the customer has assumed the risks and rewards of ownership. We have supplier managed inventory arrangements with some of our customers to facilitate on-demand product availability. In some cases, the inventory resides at a customer site, although title has not transferred, we are not entitled to payment, and we have not invoiced for the product. We have evaluated the contract terms under these arrangements and have determined that control transfers when the customer uses the product, at which time revenue is recognized. Our contracts generally include one performance obligation, which is providing petroleum additives products. The performance obligation is satisfied at a point in time when products are shipped, delivered, or consumed by the customer, depending on the underlying contracts.

Taxes assessed by a governmental authority which are concurrent with sales to our customers, including sales, use, value-added, and revenue-related excise taxes, are collected by us from the customer and are not included in net sales, but are reflected in accrued expenses until remitted to the appropriate governmental authority. When we are responsible for shipping and handling costs after title has transferred, we account for those as fulfillment costs and include them in cost of goods sold.

Some of our contracts include variable consideration in the form of rebates or business development funds. We record rebates at the point of sale as contra-revenue when we can reasonably estimate the amount of the rebate. The estimates are based on our best judgment at the time of sale, which includes anticipated as well as historical performance. Depending upon the specific terms of a business development fund, amounts are accrued as contra-revenue at the point of sale or are expensed when costs are incurred by us. We regularly review both rebates and business development funds and make adjustments when necessary, recognizing the full amount of any adjustment in the period identified. We recognized an increase to net sales of $2 million for 2020, $1 million for 2019, and $3 million for 2018 related to adjustments to rebates or business development funds which were recognized in revenue in a prior period. At December 31, 2020, accrued rebates were $24 million and accrued business development funds were $1 million. At December 31, 2019, accrued rebates were $23 million and accrued business developments funds were $2 million.

3. Earnings Per Share

We had 19,951 shares in 2020, 20,441 shares in 2019, and 18,892 shares in 2018 of nonvested restricted stock that were excluded from the calculation of diluted earnings per share, as their effect on earnings per share would be anti-dilutive.

The nonvested restricted stock is considered a participating security since the restricted stock contains nonforfeitable rights to dividends. As such, we use the two-class method to compute basic and diluted earnings per share for all periods presented since this method yields the most dilutive result. The following table illustrates the earnings allocation method utilized in the calculation of basic and diluted earnings per share.

4. Segment and Geographic Area Information

Segment Information—The tables below show our consolidated segment results. The “All other” category includes the operations of the antiknock compounds business, as well as certain contracted manufacturing and services associated with Ethyl.

The segment accounting policies are the same as those described in Note 1. We evaluate the performance of the petroleum additives business based on segment operating profit. NewMarket Services departments and other expenses are billed to Afton and Ethyl based on the services provided under the holding company structure. Depreciation on segment property, plant, and equipment, as well as amortization of segment intangible assets and lease right-of-use assets for 2020 and 2019 are included in segment operating profit. No transfers occurred between the petroleum additives segment and the “All other” category during the periods presented. The table below reports net sales and operating profit by segment, as well as a reconciliation to income before income tax expense, for the last three years.

Aggregate amortization expense			$	2,907			$	4,206

Aggregate amortization expense was $7 million in 2018. All of the intangibles relate to the petroleum additives segment. The change in the gross carrying amount between 2019 and 2020 was due to foreign currency fluctuations, as well as the following:

•A formulas and technology intangible asset became fully amortized in 2020, resulting in a decrease in the gross carrying amount and accumulated amortization.

•In May 2020, we completed the purchase of the remaining outstanding capital stock of Aditivos Mexicanos, S.A. de C.V. (AMSA), which we acquired in 2017. The prior noncontrolling interest represented by the outstanding capital stock of AMSA was not material.

There is no accumulated goodwill impairment.

Revolving credit facility	0		44,678

	$	598,848	$	642,941

4.10% Senior Notes – In 2012, we issued $350 million aggregate principal amount of 4.10% senior notes due 2022 at an issue price of 99.83%. The notes are senior unsecured obligations. We incurred financing costs totaling approximately $5 million related to the 4.10% senior notes, which are being amortized over the term of the agreement. Interest is payable semiannually.

The 4.10% senior notes rank:

•equal in right of payment with all of our existing and future senior unsecured indebtedness; and

•senior in right of payment to any of our future subordinated indebtedness.

The indenture governing the 4.10% senior notes contains covenants that, among other things, limit our ability and the ability of our subsidiaries to:

•create or permit to exist liens;

•enter into sale-leaseback transactions;

•incur additional guarantees; and

•sell all or substantially all of our assets or consolidate or merge with or into other companies.

We were in compliance with all covenants under the indenture governing the 4.10% senior notes as of December 31, 2020 and December 31, 2019.

3.78% Senior Notes – On January 4, 2017, we issued $250 million in senior unsecured notes in a private placement with The Prudential Insurance Company of America and certain other purchasers. These notes bear interest at 3.78% and mature on January 4, 2029. Interest is payable semiannually. Principal payments of $50 million are payable annually beginning on January 4, 2025. We have the right to make optional prepayments on the notes at any time, subject to certain limitations. The note purchase agreement contains representations, warranties, terms and conditions customary for transactions of this type. These include negative covenants, certain financial covenants and events of default which are substantially similar to the covenants and events of default in our revolving credit facility.

We were in compliance with all covenants under the 3.78% senior notes as of December 31, 2020 and December 31, 2019.

Revolving Credit Facility - On March 5, 2020, NewMarket and certain foreign subsidiary borrowers entered into a Credit Agreement (the Credit Agreement) with a term of five years. The Credit Agreement provides for a $900 million, multicurrency revolving credit facility with a $500 million sublimit for foreign currency borrowings, a $50 million sublimit for letters of credit, and a $20 million sublimit for swingline loans. The Credit Agreement includes an expansion feature which allows us, subject to certain conditions, to request an increase in the aggregate amount of the revolving credit facility or obtain incremental term loans in an amount up to $425 million. NewMarket's obligations under the Credit Agreement are unsecured and the obligations of foreign subsidiary borrowers are fully and unconditionally guaranteed by NewMarket. The revolving credit facility is available on a revolving basis until March 5, 2025.

Concurrent with entering into the Credit Agreement, we terminated our former revolving credit facility that we had entered into in 2017.

Borrowings made under the revolving credit facility bear interest, at our option, at an annual rate equal to (1) the Alternate Base Rate (ABR) plus the Applicable Rate (as defined in the Credit Agreement) solely in the case of loans

Table of Contents

Notes to Consolidated Financial Statements

denominated in U.S. dollars to NewMarket, (2) the Adjusted LIBO Rate plus the Applicable Rate, or (3) the Adjusted EURIBO Rate plus the Applicable Rate. ABR is the greatest of (i) the rate of interest publicly announced by the Administrative Agent as its prime rate, (ii) the NYFRB Rate (as defined in the Credit Agreement) from time to time plus 0.5%, and (iii) the Adjusted LIBO Rate for a one month interest period plus 1%. The Adjusted LIBO Rate means the rate at which Eurocurrency deposits in the London interbank market for certain periods (as selected by NewMarket) are quoted, as adjusted for statutory reserve requirements for Eurocurrency liabilities and other applicable mandatory costs. The Adjusted EURIBO Rate means the rate at which Eurocurrency deposits denominated in euro in the euro interbank markets for certain periods (as selected by NewMarket) are quoted, as adjusted for statutory reserve requirements for Eurocurrency liabilities and other mandatory costs. The Applicable Rate ranges from 0.000% to 0.375% (depending on our Leverage Ratio or Credit Ratings) for loans bearing interest based on the ABR. The Applicable Rate ranges from 0.875% to 1.375% (depending on our Leverage Ratio or Credit Ratings) for loans bearing interest based on the Adjusted LIBO Rate or the Adjusted EURIBO rate. The Credit Agreement contains the Administrative Agent's customary LIBOR successor rate provisions, which apply in the event LIBOR ceases to be available or is generally replaced as a benchmark interest rate in the market.

We paid financing costs in 2020 of approximately $1.3 million related to this revolving credit facility and carried over deferred financing costs from our previous revolving credit facility of approximately $1.2 million, resulting in total deferred financing costs of $2.5 million, which we are amortizing over the term of the Credit Agreement.

The average interest rate for borrowings under the credit facilities was 1.4% during 2020 and 3.0% during 2019.

The Credit Agreement contains certain customary covenants, including financial covenants that require NewMarket to maintain a consolidated Leverage Ratio (as defined in the Credit Agreement) of no more than 3.75 to 1.00 except during an Increased Leverage Period (as defined in the Credit Agreement). We were in compliance with all covenants under the revolving credit facility in effect at December 31, 2020 and at December 31, 2019.

15. Stock-based Compensation

The 2014 Incentive Compensation and Stock Plan (the Plan) was approved on April 24, 2014. Any employee of our company or an affiliate or a person who is a member of our Board of Directors or the board of directors of an affiliate is eligible to participate in the Plan if the Compensation Committee of the Board of Directors (the Administrator), in its sole discretion, determines that such person has contributed or can be expected to contribute to the profits or growth of our company or its affiliates (each, a participant). Under the terms of the Plan, we may grant participants stock awards, incentive awards, stock units, or options (which may be either incentive stock options or nonqualified stock options), or stock appreciation rights (SARs), which may be granted with a related option. Stock options entitle the participant to

Table of Contents

Notes to Consolidated Financial Statements

purchase a specified number of shares of our common stock at a price that is fixed by the Administrator at the time the option is granted; provided, however, that the price cannot be less than the shares’ fair market value on the date of grant. The maximum period in which an option may be exercised is fixed by the Administrator at the time the option is granted but, in the case of an incentive stock option, cannot exceed 10 years. No participant may be granted or awarded, in any calendar year, shares, options, SARs, or stock units covering more than 200,000 shares of our common stock in the aggregate. For purposes of this limitation and the individual limitation on the grant of options, an option and corresponding SAR are treated as a single award.

The maximum aggregate number of shares of our common stock that may be issued under the Plan is 1,000,000. At December 31, 2020, 954,028 shares were available for grant. During 2020, we granted 1,120 shares to five of our non-employee directors, which vested immediately.

A summary of activity during 2020 related to NewMarket’s restricted stock and restricted stock units (stock awards) is presented below in whole shares:


	Number of Shares	Weighted Average Grant-Date Fair Value
Unvested stock awards at January 1, 2020	21,111	$	427.14
Granted in 2020	6,779	414.33
Vested in 2020	4,708	428.54
Forfeited in 2020	2,268	428.07
Unvested stock awards at December 31, 2020	20,914	422.57

The weighted average grant-date fair value was $440.42 for stock awards granted in 2019 and $415.98 for stock awards granted in 2018. The fair value of shares vested was $2 million in 2020, $1 million in 2019, and $3 million in 2018. We recognized compensation expense of $2 million in 2020, $2 million in 2019, and $2 million in 2018 related to stock awards. At December 31, 2020, total unrecognized compensation expense related to stock awards was $5 million, which is expected to be recognized over a period of 3.1 years.

16. Leases

Our leases are for land, real estate, railcars, vehicles, pipelines, plant equipment, and office equipment. We have both operating and finance leases with remaining terms ranging from less than one year to 50 years. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

The components of lease expense were as follows:

Most of the commitments relate to plant and equipment that is being constructed or procured by the future lessors. These leases are expected to commence in 2021.

17. Pension Plans and Other Postretirement Benefits

NewMarket uses a December 31 measurement date for all of our plans.

U.S. Retirement Plans

NewMarket sponsors four pension plans for all full-time U.S. employees that offer a benefit based primarily on years of service and compensation. Employees do not contribute to these pension plans. The plans are as follows:

•Salaried employees pension plan;

•Afton pension plan for union employees (the Sauget plan);

•NewMarket retirement income plan for union employees in Houston, Texas (the Houston plan); and

•Afton Chemical Additives pension plan for union employees in Port Arthur, Texas (the Port Arthur plan).

In addition, we offer an unfunded, nonqualified supplemental pension plan. This plan restores the pension benefits from our regular pension plans that would have been payable to designated participants if it were not for limitations imposed by U.S. federal income tax regulations. We also provide postretirement health care benefits and life insurance to eligible retired employees.

The service cost component of net periodic benefit cost (income) is included in cost of goods sold; selling, general, and administrative expenses; or research, development, and testing expenses, to reflect where other compensation costs arising from services rendered by the pertinent employee are recorded on the Consolidated Statements of Income. The remaining components of net periodic benefit cost (income) are recorded in other income (expense), net on the Consolidated Statements of Income.

The accumulated benefit obligation for all domestic defined benefit pension plans was $392 million at December 31, 2020 and $346 million at December 31, 2019.

The fair market value of plan assets exceeded both the accumulated benefit obligation and projected benefit obligation for all domestic plans, except the nonqualified plan, at December 31, 2020 and December 31, 2019.

The net asset position for plans in which assets exceeded the projected benefit obligation is included in prepaid pension cost on the Consolidated Balance Sheets. The net liability position of plans in which the projected benefit obligation exceeded assets is included in other noncurrent liabilities on the Consolidated Balance Sheets.

A portion of the accrued benefit cost for the nonqualified plan is included in current liabilities at both December 31, 2020 and December 31, 2019. As the nonqualified plan is unfunded, the amount reflected in current liabilities represents the expected benefit payments related to the nonqualified plan during 2021.

There are no assets held by the trustee for the retired beneficiaries of the nonqualified plan. Payments to retired beneficiaries of the nonqualified plan are made with cash from operations. The postretirement healthcare benefits are also unfunded and paid with cash from operations. The benefits from the postretirement life insurance are funded through an insurance contract.

Assumptions—We used the following assumptions to calculate the results of our retirement plans:


	Pension Benefits						Postretirement Benefits
	2020		2019		2018		2020		2019		2018
Weighted-average assumptions used to determine net periodic benefit cost (income) for years ended December 31,

Expected long-term rate of return on plan assets	8.50	%	8.50	%	8.50	%	4.50	%	4.50	%	4.50	%

Rate of projected compensation increase	3.50	%	3.50	%	3.50	%

For pension plans, we base the assumed expected long-term rate of return for plan assets on an analysis of our actual investments, including our asset allocation, as well as an analysis of expected returns. This analysis reflects the expected long-term rates of return for each significant asset class and economic indicator. The range of returns relies both on forecasts and on broad-market historical benchmarks for expected return, correlation, and volatility for each asset class. Our asset allocation is predominantly weighted toward equities. Through our ongoing monitoring of our investments and review of market data, we have determined that we should reduce the expected long-term rate of return for our U.S. plans to 8.0% for the year beginning January 1, 2021. For the postretirement plan, we based the assumed expected long-term rate of return for plan assets on an evaluation of projected interest rates, as well as the guaranteed interest rate for our insurance contract.

Plan Assets—Pension plan assets are held and distributed by trusts and consist principally of equity securities and investment-grade fixed income securities. We invest directly in equity securities, as well as in funds which primarily

Table of Contents

Notes to Consolidated Financial Statements

hold equity and debt securities. Our target allocation is 90% to 97% in equities, 3% to 10% in debt securities and 1% to 5% in cash.

The pension obligation is long-term in nature and the investment philosophy followed by the Pension Investment Committee is likewise long-term in its approach. The majority of the pension funds are invested in equity securities as historically, equity securities have outperformed debt securities and cash investments, resulting in a higher investment return over the long-term. While in the short-term, equity securities may underperform other investment classes, we are less concerned with short-term results and more concerned with long-term improvement. The pension funds are managed by several different investment companies who predominantly invest in U.S. and international equities. Each investment company’s performance is reviewed quarterly. A small portion of the funds is in investments such as cash or short-term bonds, which historically has been less vulnerable to short-term market swings. These funds are used to provide the cash needed to meet our monthly obligations.

There are no significant concentrations of risk within plan assets, nor do the equity securities include any NewMarket common stock for any year presented.

The assets of the postretirement benefit plan are invested completely in an insurance contract. No NewMarket common stock is included in these assets.

The following table provides information on the fair value of our pension and postretirement benefit plans assets, as well as the related level within the fair value hierarchy. Investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified by level in the fair value hierarchy.

The valuation methodologies used to develop the fair value measurements for the investments in the table above are outlined below. There have been no changes in the valuation techniques used to value the investments.

•Equity securities, including common stock and real estate investment trusts, are valued at the closing price reported on a national exchange.

Table of Contents

Notes to Consolidated Financial Statements

•Money market instruments are valued at cost, which approximates fair value.

•Pooled investment funds—Mutual funds are valued at the closing price reported on a national exchange.

•The common collective trusts (the trusts) are valued at the net asset value of units held based on the quoted market value of the underlying investments held by the funds. One of the trusts invests primarily in a diversified portfolio of equity securities of companies located outside of the United States and Canada, as determined by a company's jurisdiction of incorporation. We may make withdrawals from this trust on the first business day of each month with at least 10 days notice. Another trust invests primarily in a diversified portfolio of equity securities included in the S&P 500 index and a third trust invests primarily in a diversified portfolio of equity securities included in the Russell 1000 Value index. There are no restrictions on redemption for the index trusts and there were no unfunded commitments.

•Cash and cash equivalents are valued at cost.

•The insurance contracts are unallocated funds deposited with an insurance company and are stated at an amount equal to the sum of all amounts deposited less the sum of all amounts withdrawn, adjusted for investment return.

Cash Flows—For U.S. plans, NewMarket expects to contribute $3 million to our pension plans and $2 million to our postretirement benefit plan in 2021. The expected benefit payments for the next ten years are as follows.

Foreign Retirement Plans

For most employees of our foreign subsidiaries, NewMarket has defined benefit pension plans that offer benefits based primarily on years of service and compensation. These defined benefit plans provide benefits for employees of our foreign subsidiaries located in Belgium, the U.K., Germany, Canada, and Mexico. NewMarket generally contributes to investment trusts and insurance accounts to provide for these plans.

The accumulated benefit obligation for all foreign defined benefit pension plans was $224 million at December 31, 2020 and $171 million at December 31, 2019.

The fair market value of plan assets exceeded both the accumulated benefit obligation and projected benefit obligation for the Canada plan at both year-end 2020 and 2019. The net asset position of the Canada plan is included in prepaid pension cost on the Consolidated Balance Sheets at December 31, 2020 and December 31, 2019. The fair market value of plan assets for the U.K. plan exceeded the accumulated benefit obligation but not the projected benefit obligation at yearend 2020. For yearend 2019, the fair market value of plan assets of the U.K. plan exceeded both the accumulated benefit obligation and projected benefit obligation. The accrued benefit cost of the U.K. plan is included in other noncurrent liabilities on the Consolidated Balance Sheets at December 31, 2020 and the net asset position is included in prepaid pension cost on the Consolidated Balance Sheets at December 31, 2019. The accumulated benefit obligation and projected benefit obligation exceeded the fair market value of plan assets for the Germany, Belgium, and the two Mexico plans at December 31, 2020 and December 31, 2019. The accrued benefit cost of these plans is included in other noncurrent liabilities on the Consolidated Balance Sheets for both years.

The actuarial assumptions used by the various foreign locations are based upon the circumstances of each particular country and pension plan. The factors impacting the determination of the long-term rate of return for a particular foreign pension plan include the market conditions within a particular country, as well as the investment strategy and asset allocation of the specific plan.

Plan Assets—Pension plan assets vary by foreign location and plan. Assets are held and distributed by trusts and, depending upon the foreign location and plan, consist primarily of pooled equity funds, pooled debt securities funds, pooled diversified funds, equity securities, debt securities, cash, and insurance contracts. The combined weighted-average target allocation of our foreign pension plans is 38% in equities (including pooled funds), 37% in debt securities (including pooled funds), 6% in insurance contracts, and 19% in pooled diversified funds.

While the pension obligation is long-term in nature for each of our foreign plans, the investment strategies followed by each plan vary to some degree based upon the laws of a particular country, as well as the provisions of the specific pension trust. The U.K. and Canada plans are invested predominantly in equity securities funds, diversified funds, and debt securities funds. The funds of these plans are managed by various trustees and investment companies whose performance is reviewed throughout the year. The Belgium plan is invested in an insurance contract. The Mexico plans are invested in various mutual funds, equities, and debt securities. The Germany plan has no assets.

There are no significant concentrations of risk within plan assets, nor do the equity securities include any NewMarket common stock for any year presented.

•Cash and cash equivalents are valued at cost.

•The pooled investment funds are valued at the net asset value of units held by the plans based on the quoted market value of the underlying investments held by the fund. The U.K. pension plan is invested in units of life insurance policies that are linked to equity securities funds, government bond funds and diversified growth funds. The underlying assets of the equity funds, bond funds, and diversified growth funds are traded on a national exchange and are based on tracking various indices of the London Stock Exchange. There are no redemption restrictions on these funds. There were no unfunded commitments for the U.K. pension plan funds. The Canada pension plan is invested in a pooled Canadian equity fund and a pooled diversified fund. The Canadian equity fund invests in a diversification (sector and industry) of equities listed on a recognized Canadian exchange. The diversified fund invests in a diversified mix of equities, fixed income securities, cash, and cash equivalent securities. There are no redemption restrictions on the pooled Canadian funds and there were no unfunded commitments.

Cash Flows—For foreign pension plans, NewMarket expects to contribute $7 million to the plans in 2021. The expected benefit payments for the next ten years for our foreign pension plans are shown in the table below.

Net deferred income tax (liabilities) assets in the table above are reflected in the Consolidated Balance Sheets on a net jurisdictional basis. Deferred income tax assets are included in deferred charges and other assets. See Note 11. Deferred income tax liabilities are included in other noncurrent liabilities. See Note 14.

Our deferred taxes are in a net liability position at December 31, 2020. Our deferred tax assets include $15 million of foreign operating loss carryforwards, foreign capital loss carryforwards, and foreign and state tax credits. The operating loss carryforwards expire in 2023 through 2037 and certain tax credits expire in 2026 through 2030. The largest change during 2020 on the carryforward items related to an increase in foreign tax credit carryforwards generated in 2019. Based on current forecasted operating plans and historical profitability, we believe that we will recover the full benefit of our deferred tax assets with the exception of $13 million of the aforementioned operating loss, capital loss, and tax credit carryforwards. Therefore, as of December 31, 2020, we have recorded an offsetting valuation allowance against these items. During 2020, we released the valuation allowance on $1 million of net operating losses that we utilized during the year.

Notes to Consolidated Financial Statements

As a result of the Tax Reform Act, we do not expect to distribute earnings from our foreign subsidiaries in a manner that would result in significant U.S. tax, as these earnings have been previously taxed in the U.S. or meet the requirements for a dividends received deduction. However, we have recorded a $2 million deferred tax liability for the currency impact and for the withholding taxes that will not be creditable upon distribution.

We have not provided a deferred tax liability on approximately $163 million of temporary differences related to investments in foreign subsidiaries that are essentially permanent in duration, as these earnings are considered to be indefinitely reinvested. If we were to repatriate these earnings, we could be subject to income taxes and withholding taxes in various countries. Determination of the amount of unrecognized deferred income tax liability is not practicable due to the complexity associated with the hypothetical calculation.

A reconciliation of the beginning and ending balances of the unrecognized tax benefits from uncertain positions is as follows:

Lapses of statutes	(7,825)		(556)		(927)
Balance at end of year	$	6,905	$	13,543	$	10,660

At December 31, 2020, all of the amount of unrecognized tax benefits, if recognized, would affect our effective tax rate.

We expect the amount of unrecognized tax benefits to change in the next twelve months; however, we do not expect the change to have a material impact on our financial statements.

Our U.S. subsidiaries file a U.S. federal consolidated income tax return. We are currently under examination by various U.S. state and foreign jurisdictions and remain subject to examination until the statute of limitations expires for the respective tax jurisdiction. We are no longer subject to U.S. federal income examination for years before 2017. Foreign and U.S. state jurisdictions have statutes of limitations generally ranging from 3 years to 5 years. Years still open to examination by foreign tax authorities in major jurisdictions include: the U.K. (2019 and forward); Singapore (2016 and forward); Belgium (2018 and forward); and Mexico (2015 and forward).

19. Fair Value Measurements

The carrying amount of cash and cash equivalents in the Consolidated Balance Sheets, as well as the fair value, was $125 million at December 31, 2020 and $144 million at December 31, 2019. The fair value is categorized in Level 1 of the fair value hierarchy.

No material events occurred during 2020 requiring adjustment to the recognized balances of assets or liabilities which are recorded at fair value on a nonrecurring basis.

Long-term debt - We record the carrying amount of our long-term debt at historical cost, less deferred financing costs related to the 4.10% senior notes.

Asbestos

We are a defendant in personal injury lawsuits involving exposure to asbestos. These cases involve exposure to asbestos in premises owned or operated, or formerly owned or operated, by subsidiaries of NewMarket. We have never manufactured, sold, or distributed products that contain asbestos. Nearly all of these cases are pending in Texas, Louisiana, or Illinois and involve multiple defendants. We maintain an accrual for these proceedings, as well as a receivable for expected insurance recoveries.

The accrual for our premises asbestos liability related to currently asserted claims is based on the following assumptions and factors:

•We are often one of many defendants. This factor influences both the number of claims settled against us and the indemnity cost associated with such resolutions.

•The estimated percent of claimants in each case that, after discovery, will actually make a claim against us, out of the total number of claimants in a case, is based on a level consistent with past experience and current trends.

•We utilize average comparable plaintiff cost history as the basis for estimating pending premises asbestos-related claims. These claims are filed by both former contractors and former employees who worked at past and present company locations. We also include an estimated inflation factor in the calculation.

•No estimate is made for unasserted claims.

•The estimated recoveries from insurance and Albemarle Corporation (a former operation of our company) for these cases are based on, and are consistent with, the 2005 settlement agreements with The Travelers Indemnity Company.

Based on the above assumptions, we have provided an undiscounted liability related to premises asbestos claims of $9 million at December 31, 2020 and $12 million at December 31, 2019. The liabilities related to premises asbestos claims are included in accrued expenses (current portion) and other noncurrent liabilities on the Consolidated Balance Sheets. Certain of these costs are recoverable through the settlement agreements with The Travelers Indemnity Company and with Albemarle Corporation. The receivable for these recoveries related to premises asbestos liabilities was $4 million at December 31, 2020 and $6 million at December 31, 2019. These receivables are included in trade and other accounts receivable, net on the Consolidated Balance Sheets for the current portion. The noncurrent portion is included in deferred charges and other assets.

Environmental—We are involved in environmental proceedings and potential proceedings relating to soil and groundwater contamination, disposal of hazardous waste, and other environmental matters at several of our current or former facilities, or at third-party sites where we have been designated as a PRP. While we believe we are currently adequately accrued for known environmental issues, it is possible that unexpected future costs could have a significant impact on our financial statements. Our total accruals for environmental remediation, dismantling, and decontamination were approximately $10 million at December 31, 2020 and $11 million at December 31, 2019. Of the total accrual, the current portion is included in accrued expenses and the noncurrent portion is included in other noncurrent liabilities on the Consolidated Balance Sheets.

Our more significant environmental sites include a former plant site in Louisiana (the Louisiana site) and a Houston, Texas plant site (the Texas site). Together, the amounts accrued on a discounted basis related to these sites represented approximately $8 million of the total accrual above at both December 31, 2020 and December 31, 2019, using discount rates ranging from 3% to 9%. The aggregate undiscounted amount for these sites was $9 million at December 31, 2020 and $10 million at December 31, 2019. Of the total accrued for these two sites, the amount related to remediation of groundwater and soil was $4 million for both the Louisiana site and for the Texas site at December 31, 2020 and $4 million for the Louisiana site and $3 million for the Texas site at December 31, 2019.

23. Recent Accounting Pronouncements

In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" (ASU 2020-04), which provides guidance to alleviate the burden in accounting for reference rate reform by allowing certain expedients and exceptions in applying generally accepted accounting principles to contracts, hedging relationships, and other transactions impacted by reference rate reform. The provisions of ASU 2020-04 apply only to those transactions that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. Adoption of the provisions of ASU 2020-04 is optional and is effective from March 12, 2020 through December 31, 2022. We continue to evaluate the impact of ASU 2020-04 on our consolidated financial statements, but do not currently expect a significant impact.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain a system of internal control over financial reporting to provide reasonable, but not absolute, assurance of the reliability of the financial records and the protection of assets. Under Rule 13a-15(b) of the Securities Exchange Act of 1934 (the Exchange Act), we carried out an evaluation, with the participation of our management, including our principal executive officer and our principal financial officer, of the effectiveness of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e) of the Exchange Act, as of the end of the period covered by this report. Based upon that evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures are effective at the reasonable assurance level.

There has been no change in our internal control over financial reporting, as such term is defined in Rule 13a-15(f) of the Exchange Act, during the quarter ended December 31, 2020 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) of the Securities Exchange Act of 1934.

Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. Internal control over financial reporting includes those policies and procedures that:

•pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America and that our receipts and expenditures are being made only in accordance with authorization of our management and directors; and

•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the consolidated financial statements.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in “Internal Control—Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under that framework, our management concluded that our internal control over financial reporting was effective at the reasonable assurance level as of December 31, 2020. The effectiveness of our internal control over financial reporting as of December 31, 2020, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report, which is included in Item 8 of this Annual Report on Form 10-K.
