ITEM 1A. RISK FACTORS

In addition to the risks stated elsewhere in this annual report, set forth below are certain risk factors that we believe are material. If any of these risks occur, our business, financial condition, results of operations, cash flows and reputation could be harmed. You should also consider these risk factors when you read “forward-looking statements” elsewhere in this report. You can identify forward-looking statements by terms such as “may,” “hope,” “will,” “could,” “should,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “predict,” “potential” or “continue,” the negative of those terms or other comparable terms. Those forward-looking statements are only predictions and can be adversely affected if any of these risks occur.

Risks Related to COVID 19

COVID-19 has, and is expected to continue to, adversely affect our business and results of operations

The impact of COVID-19 pandemicadversely affected our business and financial results for 2020, and we expect that it will negatively impact our business and financial results into 2021 and possibly in subsequent years depending on the length of the pandemic and its economic repercussions. As COVID-19 has spread, it has significantly impacted the health and economic environment around the world. Our customers are principally global manufacturers and the impact of the COVID-19 pandemic on general economic conditions, and more deleterious effects on certain markets, such as oil and gas, aerospace, and automotive, are having and may continue to have negative implications on demand for their goods and consequently on their demand for our products and services. Certain of our businesses are experiencing reduced levels compared to prior-year level, expectations of further reductions in sales levels could result in asset impairment charges. Because of uncertainties with respect to the severity and duration of the COVID-19 outbreak, the duration and terms of related governmental orders restricting activities, and the timing and pace of any economic recovery as COVID-19 impacts ultimately abate, we cannot predict with precision the extent and duration of any future decreased demand for our products and services and the consequent impact on our business and financial results.

In addition, our facilities and the facilities of our customers and suppliers may be prevented from conducting business activities for an indefinite period of time, and our customers may be prevented from purchasing our products, and we may be unable to purchase necessary materials from vendors, due to shutdowns, shelter-in-place orders, import restrictions or other preventative measures that may be requested or mandated by governmental authorities. Certain of our facilities have been required to temporarily close in light of governmental orders restricting business activities, and we temporarily closed certain facilities to facilitate disinfection procedures and the implementation of social distancing protocols, as well as in response to employee absences driven by COVID-19 concerns. Although most of our operations have been treated as “essential” operations under applicable government orders restricting business activities that have been issued to date, and accordingly have been permitted to continue to operate, it is possible that they may not continue to be so treated under future government orders, or, even if so treated, site-specific health and safety concerns might otherwise require certain of our operations to be halted for some period of time. The operations of all of our facilities have been affected in terms of employee protection measures, including social distancing and personal protection equipment measures. These measures will continue to affect the efficiency of our operations for the foreseeable future.

In 2020, approximately 48% of our revenues were generated outside the United States. We operate businesses with manufacturing and service facilities around the world. Accordingly, to the extent that general economic conditions in the United States may improve over time, our results of operations may continue to be adversely affected in other areas of the world that may continue to experience COVID-19 outbreaks, including as a result of delays in the administration of vaccines, and that remain subject to governmental or other health-related restrictions affecting business activities that impact the demand for our products and services or prevent us from resuming full operations in those jurisdictions.

Risks Related to Our Business

Our business and some of the markets we serve are cyclical and distressed market conditions could have a material adverse effect on our business.

The markets in which we sell our products and services, particularly chemical companies, petroleum refineries, heavy-duty trucking, semiconductor manufacturing, capital equipment and the automotive industry, are, to varying degrees, cyclical and have historically experienced periodic downturns. Prior downturns have been characterized by diminished product demand, excess manufacturing capacity and subsequent erosion of average selling prices in these markets resulting in negative effects on

9

our net sales and results of operations. A prolonged and severe downward cycle in our markets could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We face intense competition that could have a material adverse effect on our business.

We encounter intense competition in almost all areas of our businesses. Customers for many of our products and services are attempting to reduce the number of vendors from which they purchase. To remain competitive, we need to invest continuously in manufacturing, marketing, customer service and support and our distribution networks. We also need to develop new products and services to continue to meet the needs and desires of our customers. We may not have sufficient resources to continue to make such investments or maintain our competitive position. Additionally, some of our competitors are larger than we are and have substantially greater financial resources than we do. As a result, they may be better able to withstand the effects of periodic economic downturns. Certain of our products and services may also experience transformation from unique branded products to undifferentiated price sensitive products and services. This commoditization may be accelerated by low-cost foreign competition. Changes in the replacement cycle of certain of our products and services, including because of improved product and service quality or improved maintenance, may affect aftermarket demand for such products and services. Initiatives designed to distinguish our products and services through superior service, continuous improvement, innovation, customer relationships, technology, new product acquisitions, bundling with key services, long-term contracts or market focus may not be effective. Pricing and other competitive pressures could adversely affect our business, financial condition, results of operations and cash flows.

If we fail to retain the independent agents and distributors upon whom we rely to market our products, we may be unable to effectively market our products and our revenue and profitability may decline.

The marketing success of many of our businesses in the U.S. and abroad depends largely upon our independent agents’ and distributors’ sales and service expertise and relationships with customers in our markets. Many of these agents have developed strong ties to existing and potential customers because of their detailed knowledge of our products. A loss of a significant number of these agents or distributors, or of a particular agent or distributor in a key market or with key customer relationships, could significantly inhibit our ability to effectively market our products, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Increased costs for raw materials, the termination of existing supply arrangements or other disruptions of our supply chain could have a material adverse effect on our business.

The prices for some of the raw materials we purchase increased in 2020. In addition to organic changes in the prices of raw materials, the prices of some of our raw materials may increase due to the imposition (or announcement of the intended imposition) of new or increased tariffs or changes in trade laws. While we have been successful in passing along some of these higher costs, there can be no assurance we will be able to continue doing so without losing customers. Similarly, the loss of a key supplier, the unavailability of a key raw material, or other disruptions of our supply chain could adversely affect our business, financial condition, results of operations and cash flows.

If we are unable to protect our intellectual property rights and knowledge relating to our products and services, our business and prospects may be negatively impacted.

We believe that proprietary products, processes, and technology are important to our success. If we are unable to adequately protect our intellectual property and know-how, our business and prospects could be negatively impacted. Our efforts to protect our intellectual property through patents, trademarks, service marks, domain names, trade secrets, copyrights, confidentiality, non-compete and nondisclosure agreements and other measures may not be adequate to protect our proprietary rights. Patents issued to third parties, whether before or after the issue date of our patents, could render our intellectual property less valuable. Questions as to whether our competitors’ products or services infringe our intellectual property rights or whether our products and services infringe our competitors’ intellectual property rights may be disputed. In addition, intellectual property rights may be unavailable, limited or difficult to enforce in some jurisdictions, which could make it easier for competitors to capture market share in those jurisdictions.

Our competitors may capture market share from us by selling products that claim to mirror the capabilities of our products or technology. Without sufficient protection nationally and internationally for our intellectual property, our competitiveness worldwide could be impaired, which would negatively impact our growth and future revenue. As a result, we may be required to spend significant resources to monitor and enforce our intellectual property rights.

10

Failure to maintain or renew licenses to certain intellectual property rights could adversely affect our business, financial condition, results of operations and cash flows.

In general, we are the owner of the rights to the products and services that we manufacture and provide. However, we also license certain intellectual property from various entities. These licenses are subject to renewal and it is possible we may not successfully renegotiate these licenses or they could be terminated in the event of a material breach. If this were to occur, our business, financial condition, results of operations and cash flows could be adversely affected.

Our business with the U.S. government is subject to government contracting risks.

Our business with government agencies, including sales to prime contractors that supply these agencies, is subject to government contracting risks. U.S. government contracts are subject to termination by the government, either for the convenience of the government or for default as a result of our failure to perform under the applicable contract. If terminated by the government as a result of our default, we could be liable for additional costs the government incurs in acquiring undelivered goods or services from another source and any other damages it suffers. In addition, if we or one of our divisions were charged with wrongdoing with respect to a U.S. government contract, the U.S. government could suspend us from bidding on or receiving awards of new government contracts pending the completion of legal proceedings. If convicted or found liable, the U.S. government could subject us to fines, penalties, repayments and treble and other damages, and/or bar us from bidding on or receiving new awards of U.S. government contracts and void any contracts found to be tainted by fraud. The U.S. government also reserves the right to debar a contractor from receiving new government contracts for fraudulent, criminal or other seriously improper conduct.

Our products and services are often used in critical applications, which could expose us to potentially significant product liability, warranty and other claims and recalls. Our insurance coverage may be inadequate to cover all of our significant risks or our insurers may deny coverage of material losses we incur, which could adversely affect our profitability and overall financial condition.

Our products and services are often used in critical applications in demanding environments, including in the nuclear, oil and gas, automotive, aerospace and pharmaceutical industries. Accordingly, product and service failures can have significant consequences and could result in significant product liability, warranty and other claims against us, regardless of whether our products and services caused the incident that is the subject of the claim, and we may have obligations to participate in the recall of products in which our products are components, if any of the components or services we supply prove to be defective. We endeavor to identify and obtain in established markets insurance agreements to cover certain significant risks and liabilities, though insurance against some of the risks inherent in our operations (such as insurance covering down-stream customer product recalls) is either unavailable or available only at rates or on terms that we consider excessive. Depending on competitive conditions and other factors, we endeavor to obtain contractual protection against uninsured risks from our customers, including limitations on liability and indemnification. In some cases, we are unable to obtain such contractual protections, and when we do, such contractual protection may not be as broad as we desire, may not be supported by adequate insurance maintained by the customer, or may not be fully enforceable in the jurisdictions in which our customers are located. Such insurance or contractual protection may not be sufficient or effective under all circumstances or against all hazards to which we may be subject. A successful claim or product recall for which we are not insured or for which we are underinsured could have a material adverse effect on us. Additionally, disputes with insurance carriers over coverage may affect the timing of cash flows and, if litigation with the carrier becomes necessary, an outcome unfavorable to us may have a material adverse effect on our results of operations.

Our business may be adversely affected by information technology disruptions.

Our business may be impacted by information technology disruptions, including information technology attacks. Cybersecurity attacks, in particular, are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to data or corporate funds, and other electronic security breaches that could lead to disruptions in systems, unauthorized release of confidential or otherwise protected information and corruption of data (our own or that of third parties). We have been subject to these attacks, including attempts to redirect otherwise valid payments to fraudulent accounts, and although we believe that we have adopted appropriate measures and procedures to mitigate potential risks to our systems from information technology-related disruptions, it is possible that a cybersecurity attack could be successful in breaching the measures and procedures designed to protect our systems. In such an event, we could potentially be subject to production downtimes, operational delays, other detrimental impacts on our operations or ability to provide products and services to our customers, the compromising of confidential or otherwise protected information, misappropriation, destruction or corruption of data, security breaches, misappropriation of corporate funds, other manipulation or improper use of our systems or networks, financial losses from remedial actions, loss of business or potential liability, and/or damage to our reputation, any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

11

Many of the products that we manufacture are sold to industries and used in applications that are susceptible to challenges from trends to address climate change or other trends favoring “clean” energy solutions.

International trends favoring “clean” energy solutions to address climate change, sustainability and other environmental concerns may present challenges to a number of industries that we supply. These trends include increasing market replacement of vehicles powered by internal-combustion engines with electric-powered vehicles and increasing implementation of solar and wind energy solutions. In some jurisdictions, these trends have been spurred by applicable government regulation (including tax incentives), and similar or additional regulations may be adopted in the future in other jurisdictions. Furthermore, technological advances may accelerate the pace of these trends. Many of the products that we manufacture are used by industries and in applications that may face challenges from, and may be adversely affected by, these trends and, as a result, the demand for certain of our current products could be similarly adversely affected by these trends. Accordingly, we are subject to risks and uncertainties with respect to these trends. While we anticipate considering these trends in the continued development and implementation of our long-term strategy, our business and results of operations could be adversely affected by these trends if they continue or accelerate at a pace that we do not anticipate.

Our failure to develop new or improved products and services may result in a significant competitive disadvantage.

In order to maintain our market positions and margins, we need to continually develop and introduce high-quality, technologically advanced and cost-effective products and services on a timely basis, in many cases in multiple jurisdictions around the world. The failure to do so could result in a significant competitive disadvantage that could materially adversely affect our results of operations.

The loss of key personnel and an inability to attract and retain qualified employees could have a material adverse effect on our operations.

We are dependent on the continued services of our leadership team. The loss of these personnel without adequate replacement could have a material adverse effect on our operations. Additionally, we need qualified managers and skilled employees with technical and industry experience in many locations in order to operate our business successfully. From time to time, there may be a shortage of skilled labor, which may make it more difficult and expensive for us to attract and retain qualified employees. If we were unable to attract and retain sufficient numbers of qualified individuals or our costs to do so were to increase significantly, our operations could be materially adversely affected.

We identified a material weakness in our internal control over financial reporting and there can be no assurance that another material weakness will not be identified in the future.

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended. During 2019, management identified deficiencies in the Company’s internal control over financial reporting that existed on December 31, 2018, and these deficiencies constituted a material weakness in our internal control over financial reporting. A material weakness (as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended) is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented or detected on a timely basis. As a result of this material weakness, management concluded that the Company’s internal control over financial reporting was not effective based on criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in “Internal Control-Integrated Framework (2013 version)” and accordingly that the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended) were not effective. This material weakness resulted in a revision to our consolidated financial statements as of and for the year ended December 31, 2018, though the errors corrected in such revision were not material, and were related solely to the determination of the provision for income taxes. We have been actively engaged in developing and implementing a remediation plan designed to address the deficiencies in our internal control over financial reporting that led to this material weakness, and measures necessary to fully remediate the identified deficiencies were in place as of December 31, 2020. Although we have remediated these deficiencies, we cannot assure you that other material weaknesses will not occur in the future. Ineffective internal control over financial reporting could cause investors to lose confidence in our reported financial information, which could have a negative effect on the value of our common stock.

Our business could be materially adversely affected by numerous other risks, including rising healthcare costs, changes in environmental laws and other unforeseen business interruptions.

Our business may be negatively impacted by numerous other risks. For example, medical and other healthcare costs may continue to grow faster than general inflation or employees may receive more or higher cost services in future periods. Initiatives to address these costs, such as consumer driven health plan packages, may not successfully reduce these expenses to

12

the extent expected or required. Failure to offer competitive employee benefits may result in our inability to recruit or maintain key employees. Other risks to our business include potential changes in environmental rules or regulations, which could negatively impact our manufacturing processes, or changes to the magnitude of costs at existing environmental sites. Use of certain chemicals and other substances could become restricted or such changes may otherwise require us to incur additional costs which could reduce our profitability and impair our ability to offer competitively priced products. Additional risks to our business include global or local events which could significantly disrupt our operations. Terrorist attacks, natural disasters, political insurgencies, pandemics and electrical grid disruptions and outages are some of the unforeseen risks that could negatively affect our business, financial condition, results of operations and cash flows.

Risks Related to Our M&A Activities

We have made and expect to continue to make acquisitions, which could involve certain risks and uncertainties.

We expect to continue to make acquisitions in the future. Acquisitions involve numerous inherent challenges, such as properly evaluating acquisition opportunities, properly evaluating risks and other diligence matters, ensuring adequate capital availability and balancing other resource constraints. There are risks and uncertainties related to acquisitions, including: difficulties integrating acquired technology, operations, personnel and financial and other systems; unrealized sales expectations from the acquired business; unrealized synergies and cost savings; unknown or underestimated liabilities; diversion of management attention from running our existing businesses and potential loss of key management employees or customers of the acquired business. In addition, internal controls over financial reporting of acquired companies may not be up to required U.S. public company standards. Our integration activities may place substantial demands on our management, operational resources and financial and internal control systems. Customer dissatisfaction or performance problems with an acquired business, technology, service or product could also have a material adverse effect on our reputation and business.

Risks Related to Our Prior Ownership of Disposed Businesses

We have exposure to some contingent liabilities relating to previously owned businesses, which could have a material adverse effect on our financial condition, results of operations, and cash flows in any fiscal period.

We have contingent liabilities related to discontinued operations, such as Fairbanks Morse, and previously owned businesses of our predecessors, including environmental liabilities and liabilities for certain products and other matters. In some instances we have indemnified others against those liabilities, and in other instances we have received indemnities from third parties against those liabilities. For example, in 2014 when our then Fairbanks Morse division and a consortium partner entered into a multi-year arrangement with Electricite de France ("EDF") to supply opposed-piston, diesel engine generator set to EDF for emergency backup power at 20 of EDF's nuclear power plants in France, EnPro Industries, Inc. guaranteed the performance of Fairbanks Morse's obligations under agreements with our consortium partner, which guarantee continues to be in place following our sale of Fairbanks Morse, though both Fairbanks Morse and the purchaser of Fairbanks Morse have agreed to indemnify us for any payments we are required to make pursuant to such guarantee.

Claims could arise relating to products, facilities or other matters related to our discontinued operations. Some of these claims could seek substantial monetary payments. For example, EnPro has entered into an Administrative Settlement Agreement and Order on Consent for Interim Removal Action with the Environmental Protection Agency for the assessment and potential remediation of eight surface uranium mines in Arizona on the basis that our EnPro Holdings subsidiary, through which we hold most of our operating subsidiaries, was a potentially responsible party under federal environmental laws as the successor to a former operator in the 1950s of those mines. Similarly, in connection with a facility located in Water Valley, Mississippi, which was divested in 1996 and has trichloroethylene soil and groundwater contamination, EnPro has entered into an Agreed Order with the Mississippi Department of Environmental Quality pursuant to the requirements of which EnPro has developed and is implementing a corrective action work plan addressing both the sources of contamination at the facility and areas where the contamination has migrated, which include areas with residential homes and commercial and local government facilities. Further, we could potentially be liable with respect to firearms manufactured prior to March 1990 by Colt Firearms, a former operation of a corporate predecessor of EnPro Holdings, and electrical transformers manufactured prior to May 1994 by Central Moloney, another former operation of that corporate predecessor.

We have established reserves related to some of these liabilities based upon our best estimates in accordance with generally accepted accounting principles in the United States. However, if our insurance coverage is depleted or our reserves are not adequate, environmental and other liabilities relating to discontinued operations could have a material adverse effect on our financial condition, results of operations and cash flows.

13

Risks Related to Our International Operations

We conduct a significant amount of our sales and service activities outside of the U.S., which subjects us to additional business risks, including foreign exchange risks, that may cause our profitability to decline.

Because we sell our products and provide services in a number of foreign countries, we are subject to risks associated with doing business internationally. In 2020, we derived approximately 48% of our net sales from sales of our products and services outside of the U.S. Outside the U.S., we operate 26 primary manufacturing and service facilities located in 12 countries. Our sales and operating activities outside of the U.S. are, and will continue to be, subject to a number of risks, including:

•unfavorable fluctuations in foreign currency exchange rates, including long-term contracts denominated in foreign currencies;

•adverse changes in foreign tax, legal and regulatory requirements;

•difficulty in protecting intellectual property;

•government embargoes, tariffs and trade protection measures, such as “anti-dumping” duties applicable to classes of products, and import or export licensing requirements, as well as the imposition of trade sanctions against a class of products imported from or sold and exported to, or the loss of “normal trade relations” status with, countries in which we conduct business, could significantly increase our cost of products or otherwise reduce our sales and harm our business;

•cultural norms and expectations that may sometimes be inconsistent with our Code of Conduct and our requirements about the manner in which our employees, agents and distributors conduct business;

•differing labor regulations;

•political and economic instability, including instabilities associated with European sovereign debt uncertainties and the future continuity of membership of the European Union; and

•acts of hostility, terror or war.

Any of these factors, individually or together, could have a material adverse effect on our business, financial condition, results of operations and cash flows. For example, tapered roller bearings manufactured at our facilities in China that are imported into the United States before re-sale to customers are currently subject to “anti-dumping” duties imposed by the U.S. Department of Commerce based on its periodic review and analysis of our manufacturing and selling activities or the manufacturing and selling activities of larger Chinese suppliers of these products. Such duties, if imposed at higher levels, could materially adversely affect the commercial competitiveness of these products, which could adversely affect the business and results of operations of our Sealing Technologies segment.

Our operations outside the United States require us to comply with a number of United States and international regulations. For example, our operations in countries outside the United States are subject to the Foreign Corrupt Practices Act (the “FCPA”), which prohibits United States companies or their agents and employees from providing anything of value to a foreign official for the purposes of influencing any act or decision of these individuals in their official capacity to help obtain or retain business, direct business to any person or corporate entity, or obtain any unfair advantage. Our activities in countries outside the United States create the risk of unauthorized payments or offers of payments by one of our employees or agents that could be in violation of the FCPA, even though these parties are not always subject to our control. We have internal control policies and procedures and have implemented training and compliance programs with respect to the FCPA. However, we cannot assure that our policies, procedures and programs always will protect us from reckless or criminal acts committed by our employees or agents. In the event that we believe or have reason to believe that our employees or agents have or may have violated applicable anti-corruption laws, including the FCPA, we may be required to investigate or have outside counsel investigate the relevant facts and circumstances. In addition, we are subject to and must comply with all applicable export controls and economic sanctions laws and embargoes imposed by the United States and other various governments. Changes in export control or trade sanctions laws may restrict our business practices, including cessation of business activities in sanctioned countries or with sanctioned entities, and may result in modifications to compliance programs and increase compliance costs, and violations of these laws or regulations may subject us to fines, penalties and other sanctions, such as loss of authorizations needed to conduct aspects of our international business or debarments from export privileges. Violations of the FCPA or export controls or sanctions laws and regulations may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could negatively affect our business, financial condition, results of operations, and cash flows.

We intend to continue to pursue international growth opportunities, which could increase our exposure to risks associated with international sales and operations. As we expand our international operations, we may also encounter new risks that could

14

adversely affect our revenues and profitability. For example, as we focus on building our international sales and distribution networks in new geographic regions, we must continue to develop relationships with reputable and qualified local agents, distributors and trading companies. If we are not successful in developing these relationships, we may not be able to increase sales in these regions.

Failure to properly manage these risks could adversely affect our business, financial condition, results of operations and cash flows.

Risks Related to Our Capital Structure

Our debt agreement and the indenture governing our senior notes impose limitations on our operations, which could impede our ability to respond to market conditions, address unanticipated capital investments and/or pursue business opportunities.

The agreement governing our senior secured revolving credit facility and the indenture governing our senior notes impose limitations on our operations, such as limitations on certain restricted payments, investments, incurrence or repayment of indebtedness, and maintenance of a consolidated net leverage ratio and an interest coverage financial ratio. In addition, the indenture governing our senior notes contains limitations on certain restricted payments, investments and incurrence or repayment of indebtedness. These limitations could impede our ability to respond to market conditions, address unanticipated capital investment needs and/or pursue business opportunities.

We may not have sufficient cash to fund a required repurchase of our senior notes upon a change of control.

Upon a change of control, as defined under the indenture governing our senior notes and includes events that may be beyond our control, the holders of our senior notes have the right to require us to offer to purchase all of our senior notes then outstanding at a price equal to 101% of their principal amount plus accrued and unpaid interest. In order to obtain sufficient funds to pay the purchase price of the outstanding notes, we expect that we would have to refinance our senior notes. We cannot assure you that we would be able to refinance our senior notes on reasonable terms, if at all. Our failure to offer to purchase all outstanding notes or to purchase all validly tendered notes would be an event of default under the indenture governing our senior notes. Such an event of default may cause the acceleration of our other debt.

Risks Related to Ownership of Our Common Stock

The market price of our common stock may be volatile.

A relatively small number of shares are normally traded in any one day and higher volumes could have a significant effect on the market price of our common stock. The market price of our common stock could fluctuate significantly for many reasons, including in response to the risks described in this section and elsewhere in this report or for reasons unrelated to our operations, such as reports by industry analysts, investor perceptions or negative announcements by our customers, competitors or suppliers regarding their own performance, as well as industry conditions and general financial, economic and political instability.

Because our quarterly revenues and operating results may vary significantly in future periods, our stock price may fluctuate.

Our revenue and operating results may vary significantly from quarter to quarter. A high proportion of our costs are fixed, due in part to significant selling and manufacturing costs. Small declines in revenues could disproportionately affect operating results in a quarter and the price of our common stock may fall. Other factors that could significantly affect quarterly operating results include, but are not limited to:

•demand for our products and services;

•the timing and execution of customer contracts;

•the timing of sales of our products and services;

•contractual penalties for late delivery of long lead time products;

•increases in costs due to equipment or labor issues;

•changes in foreign currency exchange rates;

•changes in applicable tax rates;

•an impairment of goodwill or other intangibles at one of our reporting units;

•unanticipated delays or problems in introducing new products;

15

•announcements by competitors of new products, services or technological innovations;

•changes in our pricing policies or the pricing policies of our competitors;

•increased expenses, whether related to sales and marketing, raw materials or supplies, product development or administration;

•major changes in the level of economic activity in major regions of the world in which we do business;

•costs related to possible future acquisitions or divestitures of technologies or businesses;

•an increase in the number or magnitude of product liability or environmental claims;

•our ability to expand our operations and the amount and timing of expenditures related to expansion of our operations, particularly outside the U.S.; and

•economic assumptions and market factors used to determine postretirement benefits and pension liabilities.

Various provisions and laws could delay or prevent a change of control.

The anti-takeover provisions of our articles of incorporation and bylaws and provisions of North Carolina law could delay or prevent a change of control or may impede the ability of the holders of our common stock to change our management. In particular, our articles of incorporation and bylaws, among other things:

•require a supermajority shareholder vote to approve any business combination transaction with an owner of 5% or more of our shares unless the transaction is recommended by disinterested directors;

•limit the right of shareholders to remove directors and fill vacancies;

•regulate how shareholders may present proposals or nominate directors for election at shareholders’ meetings; and

•authorize our board of directors to issue preferred stock in one or more series, without shareholder approval.

Future sales of our common stock in the public market could lower the market price for our common stock.

In the future, we may sell additional shares of our common stock to raise capital. In addition, a reasonable number of shares of our common stock are reserved for issuance under our equity compensation plans, including shares to be issued upon the vesting of restricted stock or unit grants. We cannot predict the size of future issuances or the effect, if any, that they may have on the market price for our common stock. The issuance and sales of substantial amounts of common stock, or the perception that such issuances and sales may occur, could adversely affect the market price of our common stock.

Overview and Outlook

Overview. We design, develop, manufacture, service and market proprietary engineered industrial products. We have 45 primary manufacturing and service facilities located in 13 countries, including the United States. Over the past year and a half, we have executed several strategic initiatives to change the portfolio of businesses that we operate to focus on materials science-based businesses with leading technologies, compelling margins, strong cash flow, and high levels of recurring revenue that serve markets with favorable secular tailwinds. These initiatives, which are described below, have increased our ability to provide solutions to the semiconductor, life sciences, and other technology industries.

We manage our business as three segments: a Sealing Technologies segment, an Advanced Surface Technologies segment, and an Engineered Materials segment.

Our Sealing Technologies segment designs, manufactures and sells sealing products, including: metallic, non-metallic and composite material gaskets, dynamic seals, compression packing, resilient metal seals, elastomeric seals, custom-engineered mechanical seals for applications in the aerospace industry and other markets, hydraulic components, expansion joints, sanitary gaskets, hoses and fittings for the hygienic process industries, fluid transfer products for the pharmaceutical and biopharmaceutical industries, hole forming products, bellows and bellows assemblies, PTFE products, and heavy-duty

22

commercial vehicle parts used in wheel-end and suspension components. These products are used in a variety of industries, including chemical and petrochemical processing, pulp and paper processing, power generation, food and pharmaceutical processing, primary metal manufacturing, mining, water and waste treatment, heavy-duty trucking, aerospace, medical, filtration and semiconductor fabrication. In many of these industries, performance and durability are vital for safety and environmental protection. Many of our products are used in highly demanding applications, e.g., where extreme temperatures, extreme pressures, corrosive environments, strict tolerances, and/or worn equipment make product performance difficult.

Our Advanced Surface Technologies segment applies proprietary technologies, processes, and capabilities to deliver highly differentiated suites of products and services for the most challenging applications in high growth markets. The segment’s products and services are used in highly demanding environments requiring performance, precision and repeatability, with a low tolerance for failure. The segment’s services include cleaning, coating, testing, refurbishment and verification services for critical components and assemblies used in state-of-the-art advanced node semiconductor manufacturing equipment. The segment also designs, manufactures and sells specialized optical filters and thin-film coatings for the most challenging applications in the industrial technology, life sciences, and semiconductor markets and complex front-end wafer processing sub-systems, new and refurbished electrostatic chuck pedestals, thin film coatings, and edge-welded metal bellows for the semiconductor equipment industry and for critical applications in the space, aerospace and defense markets.

Our Engineered Materials segment includes operations that design, manufacture and sell self-lubricating, non-rolling metal-polymer, engineered plastics, and fiber reinforced composite bearing products, precision engineered components and lubrication systems for reciprocating compressors and engines, critical service flange gaskets, seals and electrical flange isolation kits used in high-pressure wellhead equipment, flow lines, water injection lines, sour hydrocarbon process applications, and crude oil and natural gas pipeline/transmission line applications. These products are used in a wide range of applications, including the automotive, aerospace, pharmaceutical, pulp and paper, natural gas, health, power generation, machine tools, air treatment, refining, petrochemical and general industrial markets.

In the fourth quarter of 2020, we evaluated our internal reporting and determined to have a new segment as the result of internal reorganizations and the acquisition of Alluxa. Our new segment, Advanced Surface Technologies, is composed of Alluxa and our semiconductor businesses, which includes our LeanTeq and Technetics Semiconductor businesses, previously reported in our Sealing Technologies segment within our Technetics reporting unit. The change involved the transfer of $180.1 million of goodwill from the Sealing Technologies segment to our Advanced Surface Technologies segment.

As a result of this transition, our Technetics reporting unit was tested for impairment both before and after the allocation of goodwill and the newly formed Semiconductor reporting unit (composed of LeanTeq and Technetics Semiconductor businesses) was tested after the allocation. We determined that the Technetics reporting unit was not impaired prior to the transfer of goodwill. After the transfer, the Technetics Sealing reporting unit was allocated $67.7 million of goodwill and, as of our allocation date of December 1, 2020, we determined it was not impaired as its fair value exceeded its carrying value by 26%. We also determined that our Semiconductor reporting unit, allocated $180.1 million of goodwill as of our allocation date of December 1, 2020, was not impaired and its fair value exceeded its carrying value by 2%. Any change in assumptions, including forecasted performance or external market information used in our fair value calculation, including the determination of our discount rate, could result in a future impairment of the goodwill allocated to the Semiconductor reporting unit.

We determined our weighted average cost of capital ("WACC") for our Semiconductor reporting unit, used in our discounted cash flow analysis, to be 12.0% at our allocation date of December 1, 2020. If the WACC used in this assessment would increase by one percentage point, we estimate that the carrying value of the Semiconductor reporting unit would exceed the fair value by approximately $20.0 million and would result in a corresponding impairment.

To estimate the fair value of our reporting units, we use both a discounted cash flow and market valuation approach. The discounted cash flow approach uses cash flow projections to calculate the fair value of each reporting unit while the market approach relies on market multiples of similar companies. The key assumptions used for the discounted cash flow approach include projected revenues and profit margins, projected capital expenditures, changes in working capital, discount rates and tax rates. The discount rate we use is based on its weighted average cost of capital. For the market approach, we choose a group of peer companies we believe is best representative of each reporting unit. We used a 75% weighting for the discounted cash flow valuation approach and a 25% weighting for the market valuation approach, reflecting our belief that the discounted cash flow valuation approach provides a better indicator of a reporting unit's value since it reflects the specific cash flows anticipated to be generated in the future by the business.

We will continue to monitor its performance as well as other market factors and test for impairment if we determine a triggering event has occurred. All other reporting units were tested at our annual test date of October 1, 2020 and their fair value exceeded their carrying value by at least 20%. We will test all reporting units again at our next test date of October 1, 2021 or earlier as circumstances may require.

23

In the second quarter of 2020 we reclassified the oil and gas component of our Garlock Pipeline Technologies ("GPT") business from the Sealing Technologies segment to the Engineered Materials segment. This reclassification allowed us to group our two oil and gas businesses, GPT and Compressor Products International, together to be managed as one business unit. The change also involved the transfer of $5.8 million of goodwill from the Sealing Technologies segment to the Engineered Materials segment. As a result of the transition of this component of the GPT business, an interim goodwill impairment test was performed in the second quarter of 2020 for all reporting units. We determined that the carrying amount of our goodwill was not impaired either before or after the reclassification.

These changes are reflected in all periods presented in Note 19, "Business Segment Information". The goodwill transfer is reflected in all periods presented in Note 9, "Goodwill and Other Intangible Assets"

In connection with the decision in the fourth quarter of 2020 to realign our reporting segments, we determined that the primary metric used by management to allocate resources and assess segment performance had shifted from segment profit to Adjusted Segment EBITDA, which is segment profit excluding acquisition and divestiture expenses, restructuring and impairment costs, non-controlling interest compensation, and depreciation and amortization.

Acquisitions

On October 26, 2020, a subsidiary of EnPro formed for this purpose (the "Alluxa Acquisition Subsidiary") acquired all of the equity securities of Alluxa, Inc. ("Alluxa"), a privately held, California-based company. Alluxa is an industrial technology company that provides specialized optical filters and thin-film coatings for the most challenging applications in the industrial technology, life sciences, and semiconductor markets. Alluxa's products are developed through a proprietary coating process using state-of-the-art advanced equipment. Alluxa is included as part of the Advanced Surface Technologies segment.

Alluxa works in collaboration with customers across major end markets to provide customized, complex precision coating solutions through its specialized technology platform and proprietary processes. Alluxa has long-standing customer relationships across its diversified customer base, serving customers across the Americas, Europe, and Asia. Founded in 2007, Alluxa has two locations in California and is headquartered in Santa Rosa, California.

The cash purchase price of Alluxa was $238.4 million, net of cash acquired. We funded the purchase with available cash and rollover equity from Alluxa executives. In connection with the completion of the transaction, we entered into a limited liability operating agreement with respect to the Alluxa Acquisition Subsidiary in connection with the rollover transaction, with three equity owners of Alluxa, who were also executives of Alluxa (the "Alluxa Executives"), receiving approximately 7% of the equity interests of the Alluxa Acquisition Subsidiary in return for their contribution of the rollover shares of Alluxa.

In connection with the consummation of the Alluxa acquisition, the Alluxa Executives entered into a limited liability operating agreement (the “Alluxa LLC Agreement”) with respect to Alluxa Subsidiary. Under the LLC Agreement, the Alluxa Executives have certain governance and information rights with respect to the Alluxa Acquisition Subsidiary and are subject to transfer restrictions with respect to their equity interests in the Alluxa Acquisition Subsidiary. Each Alluxa Executive also has the right to sell to the Company, and the Company has the right to purchase from each Alluxa Executive (collectively, the “Alluxa Put and Call Rights”), one-third of the Alluxa Executive’s equity interests in Alluxa Acquisition Subsidiary during each of three exercise periods commencing on January 1 and ending on June 30 of each of 2024, 2025 and 2026, with any amount not sold or purchased in a prior exercise period being carried forward to the subsequent exercise periods. The Alluxa LLC Agreement also provides for the purchase by the Company of all of an Alluxa Executive’s equity interests in the Alluxa Acquisition Subsidiary in connection with the termination of employment of the Alluxa Executive under specified circumstances, with payments in certain circumstances to be made in annual installments. In connection with a Alluxa Executive’s death, disability, or incapacity at any time prior to December 31, 2023 or a separation from employment for cause, including the Alluxa Executive’s breach of the non-competition and non-solicitation agreement, or a voluntary separation from employment without good reason, the consideration payable under the Alluxa LLC Agreement in connection with any such purchase by the Company of an Alluxa Executive’s equity interests in the Alluxa Acquisition Subsidiary is equal to the fixed value of the equity interests as set forth in the Alluxa LLC Agreement. In all other cases, including upon any exercise of the Alluxa Put and Call Rights, the consideration payable under the Alluxa LLC Agreement in connection with any such purchase by the Company of an Alluxa Executive’s equity interests in the Alluxa Acquisition Subsidiary is equal to the greater of the fixed value of the equity interests as set forth in the Alluxa LLC Agreement or a price based upon a multiple of twelve-month adjusted EBITDA based upon certain financial metrics of the Alluxa Acquisition Subsidiary, plus cash and less indebtedness of the Alluxa Acquisition Subsidiary prior to the relevant payment, and subject to certain adjustments dependent upon the circumstances of the purchase and sale.

On July 2, 2019, we acquired The Aseptic Group (comprising Aseptic Process Equipment SAS and Aseptic Services SARL). Headquartered in Limonest, France, The Aseptic Group distributes, designs, and manufactures aseptic fluid transfer

24

products for the pharmaceutical and biopharmaceutical industries. The Aseptic Group has been included as part of EnPro’s Garlock division within the Sealing Technologies segment.

On September 25, 2019, we acquired the outstanding equity securities of LeanTeq, LLC and LeanTeq Co., Ltd. (collectively "LeanTeq"), a privately-held, Taiwan-based company. LeanTeq provides refurbishment services for critical components and assemblies used in state-of-the-art semiconductor equipment. The equipment is used to produce the latest and most technologically advanced microchips for smartphones, autonomous vehicles, high-speed wireless connectivity (5G), artificial intelligence, and other leading-edge applications.

LeanTeq was founded in 2011, is headquartered in Taoyuan City, Taiwan, and has two locations in Taiwan and one in the United States (Silicon Valley). LeanTeq partners closely with original equipment manufacturers throughout the development and production lifecycle to achieve Process of Record qualifications, enabling long-term, recurring aftermarket revenue. Aftermarket refurbishment services have historically represented approximately 65% of LeanTeq's total sales. LeanTeq’s suite of services includes cleaning, coating, analytical testing, inspection and verification, kit assembly, failure analysis, and other value-added services. LeanTeq is included as part of EnPro's Advanced Surface Technologies segment.

In connection with the consummation of the LeanTeq acquisition, two LeanTeq equity holders who are managers of LeanTeq (the “LeanTeq Executives”) applied approximately 10% of the total transaction consideration paid in the acquisition to purchase equity interests of our subsidiary (the “LeanTeq Acquisition Subsidiary”) acquiring LeanTeq pursuant to an agreement (the “LeanTeq LLC Agreement”) entered into upon the closing of the LeanTeq acquisition (the “LeanTeq Closing”). Under the LeanTeq LLC Agreement, each of the LeanTeq Executives will also have the right to sell to us, and we will have the right to purchase from each of the LeanTeq Executives, the LeanTeq Executive’s equity interests in the LeanTeq Acquisition Subsidiary, following the third anniversary of the Closing, a change-of-control of the LeanTeq Acquisition Subsidiary or EnPro, dissolution of the LeanTeq Acquisition Subsidiary, termination of employment, death or disability of the LeanTeq Executive, and certain other circumstances such as a dispute regarding our performance of the LeanTeq LLC Agreement. The consideration, which is payable in two installments, in such purchase and sale arrangements is generally to be based upon a multiple of twelve-month adjusted EBITDA based upon certain financial metrics of the LeanTeq Acquisition Subsidiary, plus cash and less indebtedness of the LeanTeq Acquisition Subsidiary prior to the relevant installment payment, subject to certain adjustments dependent upon the circumstances of the purchase and sale.

The combined purchase price of the LeanTeq and The Aseptic Group acquisitions was approximately $338.5 million, net of cash acquired and including the equity rollover from the LeanTeq Executives.

Dispositions

On December 31, 2020, we sold the shares of Technetics Group UK Limited ("Technetics Group UK") for a nominal cash purchase price. As part of the agreement with the buyer, we delivered to the buyer £148,000 of cash to fund value added tax ("VAT") payments due for VAT liabilities already incurred and £50,000 for working capital. We incurred a loss upon the sale of approximately £976,000 ($1.3 million).

On November 30, 2020, we closed on the sale of our bushing block business in our the Engineered Materials segment principally located in Dieuze, France. Prior to finalizing the sale of the business, we determined it to be impaired and recorded a $6.2 million impairment charge that consisted of $1.8 million of non-cash impairments of long-lived assets and $4.4 million of cash payments due to the buyer at closing. The impairment charge was recorded in other operating expenses on our consolidated statement of operations. Upon closing of the business, we recorded a $0.1 million gain on the sale of business in other non-operating expense on our consolidated statement of operations. Total charges related to the exit of our bushing block business were $6.1 million.

On November 20, 2020, we completed the sale of the Air Springs portion of our heavy-duty trucking business for $23.1 million in cash, net of an estimated working capital adjustment and fees, and a long-term promissory note with a fair-value of $6.4 million (face value of $7.5 million). As part of the agreement with the buyer, we retained the U.S. accounts receivable for the business, which created a large working capital adjustment at closing. The amount of retained accounts receivable in the U.S. was approximately $8.6 million. The purchase price is subject to final working capital adjustments. In the fourth quarter of 2020, we recorded a $0.1 million non-cash loss on sale of business to in the fourth quarter of 2020.

In August of 2020, subsequent to announcing the exit of our Motor Wheel® brake drum and Crewson® brake adjuster brands in the second quarter of 2020, we identified a buyer and entered into a definitive agreement to sell the assets related to the businesses. On September 2, 2020, we completed the sale for $8.9 million, net of transaction fees. This transaction resulted in a $3.1 million loss on sale of the business in other non-operating expense on our consolidated statements of operations, composed of a $3.0 million non-cash loss on the sales of assets and a $0.1 million loss on other expenses. Prior to finding a buyer of the brands, we determined the assets were impaired and recorded restructuring and impairment charges of $7.4 million

25

in other operating expenses on our consolidated statements of operations. Total losses on the exit of our Motor Wheel® brake drum and Crewson® brake adjuster brands recorded in 2020 were $10.5 million.

In the second quarter of 2020 we entered into an agreement to sell the Lunar® air disc brake business located in both the U.S. and in Shanghai, China. The sale of the U.S. assets of the business closed in the third quarter of 2020 for $0.3 million, resulting in a gain of $0.2 million recorded in non-operating income on our consolidated statement of operations. The sale of the Lunar® manufacturing facility located in Shanghai, China closed in the fourth quarter of 2020 for $0.9 million, resulting in no gain or loss. Prior to closing on the sale of the business, we determined the assets to be impaired and recorded a $2.1 million impairment charge, of which $1.6 million was related to impairment of long-lived assets and $0.5 million related to the impairment of inventory. The impairment of long-lived assets was recorded in other operating expense and the impairment of inventory was recorded in cost of sales on our consolidated statement of operations. Total net loss related to the exit of the Lunar® air disc brake business was $1.9 million.

On December 12, 2019, certain of our subsidiaries entered into a Membership Interest Purchase Agreement with Arcline FM Holdings, LLC (“Arcline FM Holdings”), an affiliate of Arcline Investment Management, LP, pursuant to which we agreed to transfer all of the outstanding equity interests in our indirect subsidiary, Fairbanks Morse, LLC (“Fairbanks Morse”), to Arcline FM Holdings and to cause one of our subsidiaries to sell certain related Canadian assets to an affiliate of Arcline FM Holdings, for an aggregate purchase price of $450 million. This divestiture transaction was completed on January 21, 2020. Fairbanks Morse manufactured heavy-duty, medium-speed reciprocating engines used primarily in marine and power generation applications and comprised our entire Power Systems segment. In light of the entry into the definitive agreement in December 2019 to divest Fairbanks Morse, we classified the Power Systems segment as a discontinued operation for the fourth quarter and full year 2019, and all prior quarterly and annual financial results of EnPro have been recast to reflect the Power Systems segment as a discontinued operation. Unless otherwise indicated, amounts discussed in this Item 8 pertain to continuing operations only (see Note 2 to our Consolidated Financial Statements in this Form 10-K for information on discontinued operations and the disposition of Fairbanks Morse).

In September 2019, we sold certain assets and certain liabilities of our brake products business unit located in Rome, Georgia, which was included in our Sealing Technologies segment. The aggregate sales price for the transaction was $6.8 million, of which we received $3.6 million in September 2019 at the closing of the sale of the business and $0.1 million in the fourth quarter of 2019 that was applied to the sale of the building, which closed in February 2020. On the closing of the sale of the building, we received $2.9 million and received the balance of $0.2 million in the fourth quarter of 2020.

After attempts to sell the ATDynamics business during the fourth quarter of 2019, in January 2020, we decided to shut down the ATDynamics business (an asset group in the Stemco division of our Sealing Technologies segment). As a result of the unsuccessful sales process, we reviewed the carrying amounts of long-lived assets at December 31, 2019 and determined the carrying amounts were not recoverable. As a result of this assessment, we recorded a $2.6 million impairment loss in the fourth quarter of 2019. In connection with the decision to shut down the business, we decided to not complete and sell the inventory we had on hand and recognized a $1.5 million inventory impairment.

We review the carrying amounts of long-lived assets when certain events or changes in circumstances indicate that the carrying amounts may not be recoverable. In 2020, sales declines by businesses utilizing two of the indefinite-lived trademarks within our Sealing Technologies segment were determined to be triggering events for an impairment analysis. Based on the results of this analysis, we recorded a $16.1 million impairment of indefinite-lived trademarks in the third quarter.

In the fourth quarter of 2019, in consideration of the financial performance of the Motorwheel business, an asset group in the Stemco division of our Sealing Technologies segment, we determined that a test of Motorwheel's recoverability was required. As a result of this test, all long-lived assets of Motorwheel were determined to be impaired, resulting in an impairment loss of $21.0 million, which equaled the excess of these assets' net book value at December 31, 2019 over their fair value.

COVID-19 Response.

As COVID-19 has spread, it has significantly impacted the health and economic environment around the world. Our customers are principally global manufacturers and the impact of the COVID-19 pandemic on general economic conditions, and more deleterious effects on certain markets, such as oil and gas and automotive, are having and will continue to have negative implications on demand for their goods and consequently on their demand for our products and services. Because of uncertainties with respect to the continuing severity and duration of the COVID-19 outbreak, the duration and terms of related governmental orders restricting activities, and the timing and pace of any economic recovery as COVID-19 impacts ultimately abate, we cannot predict with precision the extent and duration of any future decreased demand for our products and services and the consequent impact on our business and financial results.

26

In March 2020, we established a COVID-19 Response and Support Team (the "Support Team"), which is made up of our global executive leadership team with representatives from each functional area within the organization. The Support Team is working diligently to manage our business continuity plans and coordinated response. We have planned for several contingency scenarios and have taken decisive, informed action to limit the spread of COVID-19 while ensuring the continuity of our businesses. We are leveraging direction from our internal safety protocols, international health organizations, such as the WHO and the Centers for Disease Control, as well as local governments. We have local response teams at each of our facilities who are available to respond to changes as they occur.

With respect to business operations and the protection of our employees, we have taken numerous actions including:

•Suspension of all non-essential travel;

•Implementation of mandatory work from home, where feasible;

•Expansion of information technology infrastructure to enable working remotely and holding virtual meetings;

•Implementation of employee testing and contact tracing;

•Restrictions on visitors to EnPro facilities;

•Training of employees in enhanced cleaning and disinfecting protocols and providing

supplemental personal protective equipment at each of our facilities;

•Safe operating procedures such as temperature scanning and the use of masks;

•Establishing social distancing protocols in our manufacturing sites;

•Implementation of quarantining policies and practices with respect to any infected employee;

•Creation of a dedicated communications platform and internal website to address questions from employees

and provide frequent updates; and,

•Development of a virtual sales platform.

Although most of our businesses are granted "essential" business status under local government safety orders around the world, we had to temporarily close several of our facilities during 2020. All of our primary manufacturing facilities are currently open and have not experienced significant supply chain disruptions. Additionally, each of our businesses has developed continuity and contingency plans, based on various scenarios in preparation for potential operational disruptions, to permit us to adjust production levels to demand. We cannot predict if and when further closures or production changes may arise as a result of implications related to the COVID-19 pandemic.

To help protect the strength of our financial position, we have implemented several measures including:

•Aggressive cost management initiatives;

•Discretionary spending reductions;

•Capital expenditure prioritization;

•Headcount optimization plans, as needed; and

•Increased working capital monitoring to ensure timely accounts receivable collections and inventory level

optimization.

Refinancing

On October 17, 2018, we issued $350.0 million of aggregate principal amount of 5.75% Senior Notes due 2026 (the "Senior Notes"). We applied the net proceeds of that offering, together with borrowings under our revolving credit facility, to redeem the outstanding $450 million of aggregate principal amount of our 5.875% Senior Notes due 2022 (the "Old Notes"). The Old Notes were redeemed at a price equal to 102.938% of the aggregate principal amount thereof plus accrued and unpaid interest to, but not including, the redemption date. We recorded a loss on the redemption of the Old Notes of approximately $18.1 million in the fourth quarter of 2018.

Pension Settlement

On June 26, 2018, we entered into an agreement to purchase a group annuity contract to transfer approximately $68 million of our outstanding pension projected benefit obligations related to certain U.S. retirees or beneficiaries. The transaction closed on July 3, 2018 and was funded with pension plan assets with a value of $70.9 million. As a result of this transaction a pretax pension settlement charge of approximately $12.8 million was recognized in the third quarter of 2018.

Outlook

Financial highlights for the years ended December 31, 2020, 2019, and 2018 are as follows

(in millions, except per share data)

Net income attributable to EnPro Industries, Inc. $ 184.4 $ 38.3 $ 19.6

1 Reconciliation of these non-GAAP measures to their respective GAAP measure are located in the "— Reconciliation of Non-GAAP Financial Measure to the Comparable GAAP Measure" at the end of this section.

During the year ended December 31, 2020, our end markets saw varied demand changes as a result of the economic impacts of the COVID-19 pandemic. Despite the impact of COVID-19 on the broader global economy, we had a strong financial performance in the fourth quarter and were able to achieve a number of important milestones as we continued to transform our business, including completion of the Alluxa acquisition and the sale of STEMCO’s Air Springs and GGB’s bushing block businesses. Full-year sales growth in semiconductor, food and pharmaceuticals, and power generation markets, including the contributions from the acquisitions of LeanTeq, the Aseptic Group, and Alluxa, was more than offset by sales weakness within the general industrial, oil and gas, heavy-duty truck, aerospace, and automotive markets resulting from the impact of the global COVID-19 pandemic. The decline in sales was also driven by the divestitures of businesses in connection with our portfolio reshaping strategy.

Our year-to-date adjusted segment EBITDA was slightly up compared to the prior year, mainly due to contributions by our acquisitions of Alluxa, LeanTeq, and Aseptic. Excluding the impact of acquisitions and divestitures and the impact foreign exchange had on our results, we saw approximately a 14.1% decrease in adjusted segment EBITDA from the prior year. This was mainly attributable to decreased sales due to the challenging conditions of COVID-19. While these challenging conditions have continued to date and some of our businesses continue to experience reduced order levels compared to prior-year levels, we will stay focused on cost management and the achieving the benefits of our portfolio reshaping to help us obtain anticipated increased adjusted segment EBITDA in 2021.

In connection with changes to our segmentation in the fourth quarter of 2020, we aligned the businesses in our Sealing Technologies segment under common leadership and are implementing a shared-services structure. The new structure will allow us to reduce complexity, while increasing efficiency and providing cost savings to the Sealing Technologies segment. We expect to incur restructuring charges in 2021 as we continue to refine the structure of the organization.

The net proceeds from the divestiture of Fairbanks Morse on January 21, 2020 have allowed us to deleverage our balance sheet. We believe our cash balance of approximately $230 million at December 31, 2020 and the availability of $389 million for future borrowings on our revolving credit facility will provide us with ample liquidity to continue the reshaping of the EnPro portfolio. We remain committed to maintaining a strong balance sheet, focusing on aftermarket exposure and recurring revenue opportunities, and leveraging the EnPro Capability Center for continuous improvement and increased value. The EnPro Capability Center is our enterprise-wide program to deploy capabilities across the company to improve productivity, efficiency, and innovation. It is based on lean manufacturing concepts to create value by maintaining world class standards, increasing cash

28

flow and margins, empowering employees with a learning and ownership-based mentality and instilling a desire to learn from others, contribute to others, and ensure company-wide commitment and accountability.

While the merger and acquisition environment has been impacted by the COVID-19 pandemic, in connection with our growth strategy, we will continue to evaluate making additional acquisitions to take advantage of opportunities that arise. We may consider making additional divestitures over time and under the right circumstances, to further our long-term strategic goals of refocusing our portfolio on businesses with compelling margins, leading technology, high cash flow return on investment, and favorable secular tailwinds.

We remain committed to our strategy to create shareholder value through earnings growth and balanced capital allocation. We remain focused on disciplined investments for organic growth and innovation, strategic acquisitions, and returning capital to shareholders through dividends and share repurchases. In October 2018, our board of directors authorized a two-year program for expenditures of up to $50.0 million of our outstanding common shares. Prior to the expiration of this authorization in October 2020, we repurchased a total of 0.3 million shares for $20.3 million, of which we repurchased 0.1 million shares for $5.3 million in 2020 and we repurchased 0.2 million shares for $15.0 million in 2019. In October of 2020, our board of directors authorized a new two-year program of up to $50.0 million for the repurchase of our common shares through October 2022. We have yet to make any repurchases under the new authorization. In February 2021, our board of directors approved an increase in the quarterly dividend from $0.26 per share to $0.27 per share.

In connection with our growth strategy, we will continue to evaluate acquisitions; however, the effect of such acquisitions cannot be predicted and therefore is not reflected in this outlook.

Depreciation and amortization expense (70.7) (67.9) (66.1)

We measure operating performance based on segment earnings before interest, income taxes, depreciation, amortization, and other selected items ("Adjusted Segment EBITDA" or "Segment AEBITDA"), which is segment profit excluding acquisition and divestiture expenses, restructuring costs, impairment charges, non-controlling interest compensation, and depreciation and amortization. Adjusted Segment EBITDA is not defined under GAAP and may not be comparable to similarly-titled measures used by other companies.

Segment profit is total segment revenue reduced by operating, restructuring and other expenses identifiable with the segment. Corporate expenses include general corporate administrative costs. Expenses not directly attributable to the segments, including corporate expenses, net interest expense, asbestos-related expenses, asset impairments, gains/losses related to the sale of assets, and income taxes are not included in the computation of segment profit. The accounting policies of the reportable segments are the same as those for EnPro.

Non-controlling interest compensation allocation represents compensation expense associated with a portion of the rollover equity from the acquisitions of LeanTeq and Alluxa being subject to reduction for certain types of employment terminations of the sellers. This expense is recorded in selling, general, and administrative expenses on our Consolidated Statements of Operations and is directly related to the terms of the acquisitions. This expense will continue to be recognized as compensation expense over the term of the put and call options associated with each of these acquisitions unless certain employment terminations have occurred.

30

Corporate expenses for 2018 reflect the reclassification of allocated personnel costs from the discontinued Power Systems segment to corporate expenses. The allocated personnel costs relate to services provided to the Power Systems segment by corporate personnel which cannot be reflected in results of discontinued operations pursuant to applicable accounting guidance. The amounts reclassified from Power Systems to corporate expenses were $2.2 million for the year ended December 31, 2018.

Other expense, net in the table above contains all items included in other (operating) expense and other expense, net on our Consolidated Statements of Operations for the years ending December 31, 2020, 2019, and 2018 with the exception of $26.2 million, $6.3 million, and $19.1 million, respectively, of segment restructuring costs and $0.7 million of corporate restructuring costs in 2019. As noted previously, restructuring costs are considered to be a part of segment profit. Additionally, other expense, net in the table above for the years ending December 31, 2020, 2019, and 2018 also includes $6.1 million, $4.1 million, and $2.6 million, respectively, of miscellaneous expenses that are either not associated with a particular segment or not considered part of administering the corporate headquarters. These expenses are included in selling, general and administrative expense on our Consolidated Statements of Operations.

2020 Compared to 2019

Sales of $1,074.0 million in 2020 decreased 10.9% from $1,205.7 million in 2019. The following table summarizes the impact of acquisitions, divestitures, and foreign currency on sales by segment:

increase/(decrease) Acquisitions and divestitures ForeignCurrency Organic Total

EnPro Industries, Inc. 0.4 % 0.2 % (11.5) % (10.9) %

Sealing Technologies (4.1) % — % (12.4) % (16.5) %

Advanced Surface Technologies 30.9 % 0.6 % 10.9 % 42.4 %

Engineered Materials — % 0.2 % (17.2) % (17.0) %

Following are the key effects of acquisitions and divestitures on sales for 2020 compared to 2019:

•Acquisition of The Aseptic Group in the third quarter of 2019 in the Sealing Technologies segment;

•Acquisition of LeanTeq in the third quarter of 2019 in the Advanced Surface Technologies segment;

•Acquisition of Alluxa in the fourth quarter of 2020 in the Advanced Surface Technologies segments;

•Exit of the brake products business unit located in Rome, Georgia in the third quarter of 2019 in the Sealing Technologies segment;

•Divestiture of Motorwheel in the third quarter of 2020 in the Sealing Technologies segment; and

•Divestiture of AirSprings in the fourth quarter of 2020 in the Sealing Technologies segment.

Following is a discussion of operating results for each segment during 2020 compared to 2019:

Sealing Technologies. Sales of $636.7 million in 2020 reflect a 16.5% decrease compared to $762.4 million in 2019. Excluding the impact of acquisition sales ($5.8 million) and divestitures sales ($43.6 million), sales were down 12.4 % or $88.9 million. This decline was due primarily to decreased demand in the heavy-duty truck, general industrial, and aerospace markets, despite growth in the food and pharmaceutical market.

Segment AEBITDA of $131.0 million in 2020 decreased 0.3% from $131.4 million in 2019. Segment AEBITDA margin increased from 17.2% in 2019 to 20.6% in 2020. Excluding the impact of Segment AEBITDA from acquisitions ($1.9 million), losses from divestitures ($5.0 million), the unfavorable impact of foreign exchange translation ($0.6 million), Segment AEBITDA was down 6.0% or $8.2 million. The Segment AEBITDA impact from our reduced sales ($44.1 million) was offset by reduced marketing and selling expenses ($8.0 million), lower travel-related expenses related to the COVID-19 pandemic ($6.3 million), decreased material costs ($5.7 million), reduced warranty charges ($5.1 million), improved product mix ($4.2 million), decreased research and development spend ($3.2 million), increased pricing ($2.9 million), and manufacturing efficiencies ($2.3 million).

Advanced Surface Technologies. Sales of $171.2 million in 2020 reflect a 42.4% increase compared to $120.2 million in 2019. Excluding the impact of sales attributable to acquisitions ($37.0 million) and the impact of favorable foreign exchange

31

translation ($0.8 million), sales were up 10.9 % or $13.1 million. This increase was driven by continued strength within the semiconductor market.

Segment AEBITDA of $47.1 million in 2020 increased 100.4% from $23.5 million in 2019. Segment AEBITDA margin increased from 19.6% in 2019 to 27.5% in 2020. Excluding the impact of Segment AEBITDA from acquisitions ($23.5 million) and the favorable impact of foreign exchange translation ($0.5 million), Segment AEBITDA was down 1.7% or $0.4 million. The Segment AEBITDA impact from our increased sales volume ($7.1 million) was offset by an unfavorable product mix and increased production costs ($7.1 million).

Engineered Materials. Sales in 2020 decreased 17.0% to $275.0 million from $331.3 million in 2019. Excluding the impact of favorable foreign exchange translation ($0.8 million), sales were down $57.1 million, or 17.2%, primarily due to weakness in automotive, oil and gas, and general industrial market despite growth in the power generation market.

Segment AEBITDA of $32.5 million in 2020 decreased from $53.7 million in 2019, a decrease of $21.2 million, or 39.5%. Segment AEBITDA margin was 11.8%, down from the 16.2% in 2019. Excluding the impact of favorable foreign exchange translation ($0.4 million), Segment AEBITDA decreased $21.7 million, or 40.4%, driven mainly by decreased sales volume ($35.3 million) and an unfavorable product mix ($4.1 million), partially offset by manufacturing savings driven by restructuring efforts ($7.2 million), reduced marketing and selling costs ($5.7 million), lower travel-related expenses ($2.8 million), and reduced incentive compensation expenses ($2.1 million).

Corporate expenses for 2020 increased $1.5 million as compared to 2019. The increase was driven primarily by higher professional fees and consulting costs ($3.3 million). These costs were partially offset by reduced travel, and meetings expenses due to the COVID-19 pandemic ($1.2 million) and less restructuring costs ($0.7 million).

Interest expense, net in 2020 decreased by $3.3 million as compared to 2019, primarily due to lower average outstanding debt.

Other expense, net in 2020 increased by $3.6 million as compared to 2019, due mainly to a $23.5 million increase in environmental charges, a $7.5 million legal settlement of a products liability claim for goods last supplied in 2008, and $2.0 million of increased miscellaneous expenses that are either not associated with a particular segment or not considered part of administering the corporate headquarters, including COVID-19 related expenses such as facility cleaning fees and personal protective equipment. The increase in environmental costs was principally due to the resolution of environmental litigation brought by the State of Mississippi to recover remediation costs it had incurred with respect to the Water Valley site ($14.0 million) and the establishment of baseline reserves in the fourth quarter for two environmental matters for which we previously did not have sufficient information to estimate a range of reasonable likely remediation costs ($25.4 million, offset by a probable recovery of $3.8 million from the U.S. government). These increases were partially offset by a $13.7 million decrease in losses on sales of businesses, $9.6 million in lower impairment charges, and a $6.3 million reduction in pension (non-service) expense.

Income tax benefit was $3.5 million in both 2020 and 2019. The effective tax rates for 2020 and 2019 were 13.2% and (79.3%) respectively.The effective tax rate for 2020 was primarily driven by the foreign rate differential associated with certain foreign divestitures and earnings that were subject to higher tax rates, the effect of these items resulted in a net $5.2 million increase in tax expense. Our effective tax rate was also impacted by global intangible low-taxed income (“GILTI”) high tax exception election and non-deductible expenses which resulted in a net $2.7 million decrease in tax expense.

Loss from continuing operations was $23.3 million, or $1.15 per share, in 2020 compared to income from continuing operations of $7.8 million, or $0.38 per share, in 2019.

2019 Compared to 2018

Sales of $1,205.7 million in 2019 decreased 5.4% from $1,274.1 million in 2018. The following table summarizes the impact of acquisitions and foreign currency by segment:

32

increase/(decrease) Acquisitions/Divestiture Foreign Currency Organic Total

EnPro Industries, Inc. (0.4) % (1.5) % (3.5) % (5.4) %

Sealing Technologies (1.7) % (1.0) % (3.5) % (6.2) %

Advanced Surface Technologies 7.8 % 0.1 % (2.5) % 5.4 %

Engineered Materials — % (3.1) % (3.6) % (6.7) %

Following are the key effects of acquisitions on sales for 2019 compared to 2018:

•Exit of the industrial gas turbine business in the second quarter of 2018 in the Sealing Technologies segment;

•Acquisition of The Aseptic Group in the third quarter of 2019 in the Sealing Technologies segment;

•Acquisition of LeanTeq in the third quarter of 2019 in the Advanced Surface Technologies segment; and

•Exit of the brake products business unit located in Rome, Georgia in the third quarter of 2019 in the Sealing Technologies segment.

Following is a discussion of operating results for each segment during 2019 compared to 2018:

Sealing Technologies. Sales of $762.4 million in 2019 reflect an 6.2% decrease compared to $813.1 million in 2018. Excluding the benefit of acquisitions ($2.5 million), sales from divestitures ($7.3 million), and favorable foreign exchange translation ($1.0 million), sales were down 3.5% or $27.6 million. This decline was due primarily to softness in heavy-duty trucking and power generation markets, partially offset by strengthening in aerospace, food and pharmaceutical, and oil and gas markets.

Segment AEBITDA of $131.4 million in 2019 decreased 4.4% from $137.4 million in 2018. Segment AEBITDA margin increased from 16.9% in 2018 to 17.2% in 2019. Excluding the impact of Segment AEBITDA from acquisitions ($1.9 million), losses from divestitures ($5.7 million) and the unfavorable impact of foreign exchange translation ($1.6 million), Segment AEBITDA was down 8.3% or $11.9 million. The decrease in Segment AEBITDA was primarily attributable to the reduced sales volume ($16.2 million) and an unfavorable product mix ($5.4 million), partially offset by increased pricing ($9.0 million), and reduced warranty charges ($3.4 million).

Advanced Surface Technologies. Sales of $120.2 million in 2019 reflect a 5.4% increase compared to $114.0 million in 2018. Excluding the impact of acquisition sales ($9.0 million) sales were down 2.5 % or $2.8 million. This decrease was driven by a semiconductor market slowdown in 2019, partially offset by gains in aerospace and oil and gas markets.

Adjusted Segment EBITDA of $23.5 million in 2019 increased 33.5% from $17.6 million in 2018. Adjusted EBITDA margins for the segment increased from 15.4% in 2018 to 19.6% in 2019. Excluding the impact from acquisitions ($4.9 million), Segment Adjusted EBITDA was up 5.7% or $1.0 million. The increase in Adjusted Segment EBITDA was driven by a favorable product mix ($1.2 million) and manufacturing efficiencies ($2.3 million), partially offset by the aforementioned decrease in sales volume ($1.5 million) and a decrease in prices ($1.3 million).

Engineered Materials. Sales in 2019 decreased 6.7% to $331.3 million from $355.0 million in 2018. Excluding the impact of unfavorable foreign exchange translation ($11.0 million), sales were down 3.6% or $12.7 million primarily due to weakness in automotive and general industrial markets, partially offset by growth in oil and gas markets.

Segment AEBITDA of $53.7 million in 2019 decreased from $60.4 million in 2018, a decrease of $6.7 million, or 11.1%. Segment AEBITDA margin for the segment was 16.2%, down from the 17.0% in 2018. Excluding the impact of unfavorable foreign exchange translation ($2.3 million), Segment AEBITDA decreased $4.4 million, or 7.3%, driven mainly by decreased sales volume ($7.9 million) and impacts of tariffs ($1.0 million), partially offset by reduced incentive compensation expense ($3.3 million) and a more favorable product mix ($1.5 million).

Corporate expenses for 2019 increased $1.5 million as compared to 2018. The increase was driven primarily by higher restructuring costs ($1.0 million), increased professional services costs ($1.0 million), the favorable impact in 2018 from recognizing share based awards at fair value due to the decline in our share price during the period ($1.3 million), and increased costs related to the sale of Fairbanks Morse ($0.8 million), partially offset by decreased research and development costs ($1.0 million) due to the discontinuance of corporate-funded research and development beginning in 2019 and reduced medical costs ($1.9 million).

33

Interest expense, net in 2019 decreased by $9.1 million as compared to 2018, primarily due to lower average outstanding debt and a $3.2 million increase in interest credits in 2019 associated with our cross-currency swap agreements.

Other expense, net in 2019 increased by $16.2 million as compared to 2018, due mainly to $25.7 million of impairment charges in 2019, a $16.3 million loss on sale of our brake products business in 2019, $1.1 million increase in environmental reserves and costs from previously disposed of businesses, partially offset by a $8.6 million less pension (non-service) costs in 2019 and a $18.1 million expense in 2018 for extinguishment of debt upon the redemption of the Old Notes.

Income tax benefit was $3.5 million in 2019 and income tax expense was $19.8 million in 2018. The effective tax rates for 2019 and 2018 were (79.3%) and 131.4%, respectively.The effective tax rate for 2019 was lower than the U.S. federal statutory income tax rate of 21.0% primarily due to the release of foreign valuation allowances, offset by tax on the global intangible low-taxed income (“GILTI”).The effect of these items resulted in a net $12.9 million decrease in tax expense. Our effective tax rate was also increased by certain of our earnings that were subject to higher tax rates in foreign jurisdictions.

Income from continuing operations was $7.8 million, or $0.38 per share, in 2019 compared to loss from continuing operations of $4.7 million, or $0.22 per share, in 2018.

Restructuring and Other Costs

We incurred $46.7 million, $35.1 million and $22.2 million of restructuring and impairment costs during the years ended December 31, 2020, 2019 and 2018, respectively.

In 2020 our Stemco business in our Sealing Technologies segment underwent significant restructuring and portfolio reshaping activities, including the exit of our Motorwheel® and Crewson® brake adjuster brands and our Lunar® air disc brake business. In our Engineered Materials segment, we were able to successfully restructure and divest our bushing block business operated in Dieuze, France. We also took significant restructuring activities in our CPI German workforce.

Additionally, sales declines by business utilizing two indefinite lived trademarks within our Sealing Technologies segment were determined to be triggering events for impairment analysis and an impairment charge was taken. Substantially all costs associated with these initiatives, as well as other smaller restructuring and impairment charges, were incurred or accrued for as of December 31, 2020. Workforce reductions in 2020 associated with our restructuring activities totaled 289 administrative and manufacturing positions. Of the $46.7 million of restructuring and impairment charges taken in 2020, $17.4 million was related to severance and other cash restructuring charges while $29.3 million was related to impairments and write-downs of assets, including long-lived and indefinite-lived intangible assets, property, plant, and equipment, and inventory.

During 2019, we conducted several restructuring activities in our Stemco division in the Sealing Technologies segment, mostly consisting of the exit of our automatic tire inflation systems and RF-based tire pressure monitoring and inflation system product lines and impairments related to intangible assets and property, plant and equipment of our Motorwheel product line. We also recorded restructuring and impairment costs related the shut down of our ATDynamics business completed in January 2020. Substantially all costs associated with these initiatives, as well as other smaller restructuring and impairment charges, were incurred or accrued for as of December 31, 2019. Workforce reductions in 2019 associated with our restructuring activities totaled 121 administrative and manufacturing positions. Of the $35.1 million of restructuring and impairment charges taken in 2019, $6.3 million was related to severance and other cash restructuring charges while $28.8 million was related to impairments and write-downs of assets, including long-lived and indefinite-lived intangible assets, property, plant, and equipment, and inventory.

In 2018, we commenced and completed the exit from our industrial gas turbine business in the Sealing Technologies segment located in Oxford, Massachusetts and we implemented a restructuring plan under which our Stemco heavy-duty truck business in the Sealing Technologies segment discontinued the manufacturing of brake drum friction. Substantially all costs associated with these initiatives were incurred in 2018, with the exception of severance costs related to our exit of the manufacturing of brake drum friction occurring in January 2019. Workforce reductions in 2018 associated with our exit from the industrial gas turbine business and other smaller targeted restructuring activities totaled 98 administrative and manufacturing positions. Of the $22.2 million of restructuring and impairment charges taken in 2019, $8.0 million was related to severance and other cash restructuring charges while $14.2 million was related to impairments and write-downs of assets, including long-lived intangible assets, property, plant, and equipment, and inventory.

Liquidity and Capital Resources

Cash requirements for, but not limited to, working capital, capital expenditures, acquisitions, and debt repayments have been funded from cash balances on hand, revolver borrowings and cash generated from operations. We are proactively pursuing acquisition opportunities. Should we need additional capital, we have resources available, which are discussed in this section under the heading “Capital Resources.”

As of December 31, 2020, we held $83.4 million of cash and cash equivalents in the United States and $146.1 million of cash outside of the United States. If the funds held outside the United States were needed for our operations in the U.S., we have several methods to repatriate without significant tax effects, including repayment of intercompany loans, distributions subject to a 100 percent dividends-received deduction for income tax purposes, or distributions of previously-taxed earnings.

Because of the transition tax, GILTI, and Subpart F provisions, undistributed earnings of our foreign subsidiaries totaling $196 million at year-end have been subjected to U.S. income tax or are eligible for the 100 percent dividends-received deduction under Section 245A of the Internal Revenue Code ("IRC") provided in the Tax Cuts and Jobs Act. Whether through the application of the 100 percent dividends received deduction, or distribution of these previously-taxed earnings, we do not intend to distribute foreign earnings that will be subject to any significant incremental U.S. or foreign tax. During 2020, we repatriated $81.4 million of earnings from our foreign subsidiaries, resulting in no incremental U.S. tax and only $2.0 million of foreign withholding taxes. As a result, we have not recognized a deferred tax liability on our investment in foreign subsidiaries.

The net operating loss (“NOL”) resulting from a 2017 deduction in connection with the funding of our asbestos settlement trust was carried back to offset federal taxable income reported in the preceding ten years. We filed an initial carryback claim in May 2018 and received federal refunds totaling $96.9 million in 2018 ($95.8 million in June 2018 and $1.1 million in July 2018) and an additional $17.5 million in February 2019. In addition, amended income tax returns for the preceding ten years were filed in December 2018 to capture foreign tax credits freed up during the carryback period, and we expect federal refunds in 2021 from those returns totaling $21.8 million. The carryback claim and the amended returns have also freed up an additional $14.9 million in foreign tax credits, of which approximately $1.6 million were utilized to offset our 2019 federal tax liability with the remaining balance utilized to reduce taxes in 2020 and 2021.

Proceeds from Disposition

On December 13, 2019, we announced the signing of a definitive agreement to sell Fairbanks Morse, which transaction closed on January 21, 2020. Net proceeds received were approximately $444.3 million, of which $143.9 million was utilized to pay off all of the then outstanding borrowings under the Revolving Credit Facility (defined below in "—Capital Resources"). Taxes on the gain of approximately $40 million were paid in 2020.

Cash Flows

Operating activities of continuing operations provided cash in the amount of $57.6 million, $130.8 million and $212.8 million in 2020, 2019 and 2018, respectively. The decrease in operating cash flows in 2020 versus 2019 was primarily attributable to increased tax payments ($58.4 million) and increased payments related to environmental remediation ($26.5 million), partially offset by improved working capital. The decrease in operating cash flow in 2019 versus 2018 was primarily attributable to higher income tax refunds in 2018 driven by the asbestos settlement trust funding payments ($86.7 million), higher insurance receipts in 2018 ($24.1), partially offset by higher income from continuing operations and lower net working capital.

Investing activities of continuing operations provided $216.1 million in 2020, used $331.1 million in 2019, and provided $1.1 million of cash in 2018. The increase in cash provided by investing activities in 2020 was primarily driven by cash received from divestitures, including the sales of Fairbanks Morse, our Air Springs business and other businesses during the year ($475.1), partially offset by cash used in the acquisition of Alluxa ($238.3 million) as compared to cash used in 2019, primarily attributable to acquisitions of LeanTeq and Aseptic ($310.5 million). The increased cash usage in 2019 as compared to 2018 was driven by $310.5 million used for acquiring businesses, $26.3 million more cash provided by investing activities in 2018 for the sale of fixed assets and businesses, primarily from the sale of land and building at Oxford, Massachusetts as we exited our industrial gas turbine business of our Technetics division in the Sealing Technologies segment, and $9.3 million provided by settling derivative contracts in 2018, partially offset by lower capital expenditures in 2019 ($14.5 million).

Financing activities of continuing operations used $167.3 million in cash in 2020, primarily attributable to net payments on our Revolving Credit Facility and Term Loan Facility (as defined below) of $138.3 million and $21.7 million in payments of dividends. Financing activities of continuing operations provided $123.8 million in 2019 primarily from $17.1 million net draw on the Revolving Credit Facility, and $149.1 million net proceeds from a new term loan facility, partially offset by $20.9 million in dividends paid and $15.0 million in cash used to repurchase stock. Financing activities used $252.4 million in 2018,

35

primarily from $118.4 million in redemption of the Old Notes, net of the net proceeds from the issuance of the Senior Notes (which terms are defined below), $56.8 million in net repayments on our revolving credit facility, $50.0 million in cash used to repurchase stock, and $20.3 million in dividends paid. Funding for this activity was mainly derived from the previously discussed tax refunds and repatriation of previously taxed earnings from our foreign subsidiaries.

Capital Resources

Senior Secured Revolving Credit Facility. On September 25, 2019, we entered into a First Amendment (the "First Amendment") to our Second Amended and Restated Credit Agreement (the "Credit Agreement”) among EnPro Industries, Inc. and EnPro Holdings, Inc. as borrowers, the guarantors party thereto, the lenders party thereto and Bank of America, N.A., as Administrative Agent, Swing Line Lender and Letter of Credit Issuer. The Credit Agreement provides for a five-year, senior secured revolving credit facility of $400.0 million (the “Revolving Credit Facility”) and a five-year, senior secured term loan facility of $150.0 million (the "Term Loan Facility" and, together with the Revolving Credit Facility, the "Facilities"). The Amended Credit Agreement also provides that the borrowers may seek incremental term loans and/or additional revolving credit commitments in an amount equal to the greater of $225.0 million and 100% of consolidated EBITDA (as defined) for the most recently ended four-quarter period for which we have reported financial results, plus additional amounts based on a consolidated senior secured leverage ratio.

Initially, borrowings under the Facilities bore interest at an annual rate of LIBOR plus 1.50% or base rate plus 0.50%, with the interest rates under the Facilities being subject to incremental increases based on a consolidated total net leverage ratio. In addition, a commitment fee accrues with respect to the unused amount of the Revolving Credit Facility at an annual rate of 0.175%, which rate is also subject to incremental increase or decrease based on a consolidated total net leverage ratio.

The Term Loan Facility amortizes on a quarterly basis in an annual amount equal to 2.50% of the original principal amount of the Term Loan Facility in each of years one through three, 5.00% of such original principal amount in year four, and 1.25% of such original principal amount in each of the first three quarters of year five, with the remaining outstanding principal amount payable at maturity.

The Facilities are subject to prepayment with the net cash proceeds of certain asset sales not reinvested in acquisitions within a specified period, casualty or condemnation events, and non-permitted debt issuances. There is no prepayment penalty for a full or partial repayment of the Facilities at any time.

The Company and EnPro Holdings are the permitted borrowers under the Revolving Credit Facility. We have the ability to add foreign subsidiaries as borrowers under the Revolving Credit Facility for up to $100.0 million (or its foreign currency equivalent) in aggregate borrowings, subject to certain conditions. Each of our domestic, consolidated subsidiaries (other than any subsidiaries that may be designated as "unrestricted" by the Company from time to time) is required to guarantee the obligations of the borrowers under the Revolving Credit Facility, and each of our existing domestic, consolidated subsidiaries has entered into the Credit Agreement to provide such a guarantee.

Borrowings under the Facilities are secured by a first-priority pledge of the following assets:

•100% of the capital stock of each domestic, consolidated subsidiary of the Company (other than unrestricted subsidiaries);

•65% of the capital stock of any first tier foreign subsidiary of the Company and its domestic, consolidated subsidiaries (other than unrestricted subsidiaries); and

•substantially all of the assets (including, without limitation, machinery and equipment, inventory and other goods, accounts receivable, certain owned real estate and related fixtures, bank accounts, general intangibles, financial assets, investment property, license rights, patents, trademarks, trade names, copyrights, chattel paper, insurance proceeds, contract rights, hedge agreements, documents, instruments, indemnification rights, tax refunds and cash) of the Company and its domestic, consolidated subsidiaries (other than unrestricted subsidiaries)

The Credit Agreement contains certain financial covenants and required financial ratios, including:

•a maximum consolidated total net leverage ratio of not more than 4.25 to 1.0 (with total debt, for the purposes of such ratio, to be net of up to $125 million of unrestricted cash of EnPro Industries, Inc. and its domestic, consolidated subsidiaries), which ratio will decrease to 4.0 to 1.0 for each fiscal quarter beginning with the fiscal quarter ending December 31, 2020 and, once so decreased, may be increased (up to three times) at the borrowers' option to not more than 4.5 to 1.0 for the for-quarter period following a significant acquisition; and

•a minimum consolidated interest coverage ratio of at least 2.5 to 1.0.

36

The Credit Agreement contains affirmative and negative covenants (subject, in each case, to customary exceptions and qualifications), including covenants that limit our ability to, among other things:

•grant liens on our assets;

•incur additional indebtedness (including guarantees and other contingent obligations);

•make certain investments (including loans and advances);

•merge or make other fundamental changes;

•sell or otherwise dispose of property or assets;

•pay dividends and other distributions and prepay certain indebtedness;

•make changes in the nature of our business;

•enter into transactions with our affiliates;

•enter into burdensome contracts; and

•modify or terminate documents related to certain indebtedness.

We were in compliance with all covenants of the Credit Agreement as of December 31, 2020. On January 19, 2021, we entered into an amendment to the credit facility that waived the requirement to prepay the Term Loan Facility with remaining excess net cash proceeds related to the sale of Fairbanks Morse that had not been reinvested in operating assets within 365 days from the date of the sale.

The borrowing availability under our Revolving Credit Facility at December 31, 2020 was $388.6 million after giving consideration to $11.4 million of outstanding letters of credit.

Senior Notes. On October 17, 2018, we completed the offering of $350 million aggregate principal amount of our 5.75% senior notes due 2026 (the "Senior Notes") and applied the net proceeds of that offering, together with borrowings under the Revolving Credit Facility, to redeem on October 31, 2018 the full $450 million aggregate principal amount of our outstanding 5.875% senior notes due 2022 (the "Old Notes"), of which $300 million aggregate principal amount were issued in 2014 and $150 million aggregate principal amount were issued in a follow-on offering in 2017. The Old Notes were redeemed at a price equal to 102.938% of the aggregate principal amount thereof plus accrued and unpaid interest to, but not including, the redemption date. We recorded a loss on the redemption of the Old Notes of approximately $18.1 million in the fourth quarter of 2018.

The Senior Notes were issued to investors at 100% of the principal amount thereof. The Senior Notes are unsecured, unsubordinated obligations of EnPro and mature on October 15, 2026. Interest on the Senior Notes accrues at a rate of 5.75% per annum and is payable semi-annually in cash in arrears on April 15 and October 15 of each year, commencing April 15, 2019. The Senior Notes are required to be guaranteed on a senior unsecured basis by each of EnPro’s existing and future direct and indirect domestic subsidiaries that is a borrower under, or guarantees, our indebtedness under the Revolving Credit Facility or guarantees any other Capital Markets Indebtedness (as defined in the indenture governing the Senior Notes) of EnPro or any of the guarantors.

On or after October 15, 2021, we may, on any one or more occasions, redeem all or a part of the Senior Notes at specified redemption prices plus accrued and unpaid interest. In addition, we may redeem a portion of the aggregate principal amount of the Senior Notes before October 15, 2021 with the net cash proceeds from certain equity offerings at a specified redemption price plus accrued and unpaid interest, if any, to, but not including, the redemption date. We may also redeem some or all of the Senior Notes before October 15, 2021 at a redemption price of 100% of the principal amount, plus accrued and unpaid interest, if any, to, but not including, the redemption date, plus a “make whole” premium.

Each holder of the Senior Notes may require us to repurchase some or all of the Senior Notes held by such holder for cash upon the occurrence of a defined “change of control” event. Our ability to redeem the Senior Notes prior to maturity is subject to certain conditions, including in certain cases the payment of make-whole amounts.

The indenture governing the Senior Notes requires us to apply the net cash proceeds of certain asset sales not reinvested in acquisitions, capital expenditures, or used to repay or otherwise reduce specified indebtedness within a specified period, to the extent the remaining net proceeds exceed a specified amount, to offer to repurchase the Senior Notes at a price equal to 100% of the principal amount thereof plus accrued and unpaid interest. At December 31, 2020, approximately $10 million of the excess net cash proceeds related to the sale of Fairbanks Morse had not yet been reinvested. We expect these remaining excess proceeds to be reinvested prior to April 25, 2021, the date at which these excess proceeds must be reinvested, or applied to reduce indebtedness, to avoid the requirement to make a Senior Notes repurchase offer with respect to the proceeds from the sale of Fairbanks Morse.

37

Share Repurchase Program

In October 2017, our board of directors authorized a new program for the repurchase of up to $50.0 million of our outstanding common shares. During 2018, we repurchased 0.7 million shares for $50.0 million under this program.

In October 2018, our board of directors authorized a two-year program for expenditures of up to $50.0 million of our outstanding common shares. Prior to the expiration of this authorization in October 2020, we repurchased a total of 0.3 million shares for $20.3 million, of which we repurchased 0.1 million shares for $5.3 million in 2020 and we repurchased 0.2 million shares for $15.0 million in 2019.

In October of 2020, our board of directors authorized a new two-year program of up to $50.0 million for the repurchased of our outstanding common shares through October 2022. We have not made any repurchases under the new authorization.

Dividends

On January 13, 2015, our board of directors adopted a policy under which it intends to declare regular quarterly cash dividends on EnPro’s common stock, with the determination of whether to declare a dividend and the amount being considered each quarter, after taking into account our cash flow, earnings, cash position, financial position and other relevant matters. In 2020, our board declared a dividend of $0.26 per share in each quarter, and on February 17, 2021 we announced that our board of directors had increased the quarterly dividend to $0.27 per share, commencing with the dividend to be paid on March 17, 2021 to all shareholders of record as of March 3, 2021. Each of the Credit Agreement and the indenture governing the Senior Notes includes covenants restricting the payment of dividends, but includes a basket permitting the payment of cash dividends of up to $50.0 million per year under the Credit Agreement and $60.0 million per year under the indenture governing the Senior Notes. Other baskets may be available under that the agreement governing the Revolving Credit Facility and the indenture governing the Senior Notes to permit the payment of dividends in excess of the respective basket amount.

Critical Accounting Policies and Estimates

The preparation of our Consolidated Financial Statements, in accordance with accounting principles generally accepted in the United States, requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures pertaining to contingent assets and liabilities. Note 1, “Overview, Basis of Presentation, Significant Accounting Policies and Recently Issued Accounting Guidance,” to the Consolidated Financial Statements describes the significant accounting policies used to prepare the Consolidated Financial Statements and recently issued accounting guidance. On an ongoing basis we evaluate our estimates, including, but not limited to, those related to bad debts, inventories, intangible assets, income taxes, warranty obligations, restructuring, pensions and other postretirement benefits, and contingencies and litigation. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances. Actual results may differ from our estimates.

We believe the following accounting policies and estimates are the most critical. Some of them involve significant judgments and uncertainties and could potentially result in materially different results under different assumptions and conditions.

Revenue Recognition

Our largest stream of revenue is product revenue for shipments of the various products discussed further in Note 19, "Business Segment Information", to our consolidated financial statements, along with a smaller amount of revenue from services that take place over a short period of time. We recognize revenue at a point in time following the transfer of control, which typically occurs when a product is shipped or delivered, depending on the terms of the sale agreement, or when services are rendered. Shipping costs billed to customers are recognized as revenue and expensed in cost of goods sold as a fulfillment cost when control of the product transfers to the customer. Payment from customers is typically due within 30 days of the sale for sales in the U.S. For sales outside of the U.S., payment terms may be longer based upon local business customs, but are typically due no later than 90 days after the sale.

Pensions and Postretirement Benefits

We and certain of our subsidiaries sponsor domestic and foreign defined benefit pension and other postretirement plans. Major assumptions used in the accounting for these employee benefit plans include the discount rate, expected return on plan assets, rate of increase in employee compensation levels and assumed health care cost trend rates. Assumptions are determined based on data available to us and appropriate market indicators, and are evaluated each year as of the plans’ measurement date. A change in any of these assumptions could have a material effect on net periodic pension and postretirement benefit costs

38

reported in the Consolidated Statements of Operations, as well as amounts recognized in the Consolidated Balance Sheets. See Note 15, "Pensions and Postretirement Benefits," to the consolidated financial statements for a discussion of pension and postretirement benefits.

Income Taxes

We use the asset and liability method of accounting for income taxes. Temporary differences arising between the tax basis of an asset or liability and its carrying amount on the Consolidated Balance Sheet are used to calculate future income tax assets or liabilities. This method also requires the recognition of deferred tax benefits, such as net operating loss carryforwards. Valuation allowances are recorded as appropriate to reduce deferred tax assets to the amount considered likely to be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to the taxable income (losses) in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the date of enactment of the change. A tax benefit from an uncertain tax position is recognized only if we believe it is more likely than not that the position will be sustained on its technical merits. If the recognition threshold for the tax position is met, only the portion of the tax benefit that we believe is greater than 50 percent likely to be realized is recorded.

Goodwill and Other Intangible Assets

We do not amortize goodwill, but instead it is subject to annual impairment testing. The goodwill asset impairment test involves comparing the fair value of a reporting unit to its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, a second step of comparing the implied fair value of the reporting unit’s goodwill to the carrying amount of that goodwill is required to measure the potential goodwill impairment loss.

To estimate the fair value of our reporting units, we use both discounted cash flow and market valuation approaches. The discounted cash flow approach uses cash flow projections to calculate the fair value of each reporting unit while the market approach relies on market multiples of similar companies. There are inherent assumptions and estimates used in developing future cash flows which require management to apply judgment to the analysis of goodwill impairment, including projected revenues and profit margins, projected capital expenditures, changes in working capital, discount rates and tax rates. For the market approach, we chose a group of peer companies we believe are representative of each respective reporting unit. We used a 75% weighting for the discounted cash flow valuation approach and a 25% weighting for the market valuation approach, reflecting our belief that the discounted cash flow valuation approach provides a better indicator of value since it reflects the specific cash flows anticipated to be generated in the future by the business.

As a result of the formation of our Advanced Surface Technologies segment and the transition of a portion of our Technetics reporting unit from the Sealing Technologies segment to the Advanced Surface Technologies segment, our Technetics reporting unit was tested for impairment both before and after the allocation of goodwill and the newly formed Semiconductor reporting unit (our LeanTeq and Technetics semiconductor business) was tested after the allocation. We determined that the Technetics reporting unit was not impaired prior to the transfer of goodwill. After the transfer, the Technetics reporting unit was allocated $67.7 million of goodwill and, as of our allocation date of December 1, 2020, we determined it was not impaired as its fair value exceeded its carrying value by 26%. We also determined that our Semiconductor reporting unit, allocated $180.1 million of goodwill as of our allocation date of December 1, 2020, was not impaired and its fair value exceeded its carrying value by 2%. Any change in assumptions, including forecasted performance or external market information used in our fair value calculation, including the determination of our discount rate, could result in a future impairment of our Semiconductor reporting unit.

We will continue to monitor the Semiconductor reporting unit's performance as well as other market factors and test for impairment if we determine a triggering event has occurred. All other reporting units were tested at our annual test date of October 1, 2020 and their fair value exceeded their carrying value by at least 20%. We will test all reporting units again at our next test date of October 1, 2021, or earlier as circumstances may require.

The fair value of intangible assets associated with acquisitions is determined using an income valuation approach. Projecting discounted future cash flows requires us to make significant estimates regarding projected revenues and profit margins, projected capital expenditures, changes in working capital, discount rates, attrition rates, royalty rates, obsolescence rates and tax rates.

Many of the factors used in assessing fair value are outside the control of management, and it is reasonably likely that assumptions and estimates will change in future periods. These changes could result in future impairments. For additional information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Overview and Outlook” as well as Notes 1 and 9 to the Consolidated Financial Statements.

Impact of Pending Accounting Pronouncements

See Note 1, "Overview, Basis of Presentation, Significant Accounting Policies and Recently Issued Accounting Guidance," to our consolidated financial statements for a discussion of recently issued accounting guidance that we have not yet adopted.

Contingencies

General

A description of certain environmental and other legal matters relating to certain of our subsidiaries is included in this section. In addition to the matters noted herein, we are from time to time subject to, and are presently involved in, other litigation and legal proceedings arising in the ordinary course of business. We believe the outcome of such other litigation and legal proceedings will not have a material adverse effect on our financial condition, results of operations and cash flows. Expenses for administrative and legal proceedings are recorded when incurred.

Environmental

Our facilities and operations are subject to federal, state and local environmental and occupational health and safety laws and regulations of the U.S. and foreign countries. We take a proactive approach in our efforts to comply with these laws and regulations as they relate to our manufacturing operations and in proposing and implementing any remedial plans that may be necessary. We also regularly conduct comprehensive environmental, health and safety audits at our facilities to maintain compliance and improve operational efficiency.

Although we believe past operations were in substantial compliance with the then applicable regulations, we or one or more of our subsidiaries are involved with various remediation activities or an investigation to determine responsibility for environmental conditions at 20 sites. At 14 of these 20 sites, the future cost per site for us or our subsidiary is expected to exceed $100,000. Of these 20 sites, 18 are sites where we or one or more of our subsidiaries formerly conducted business operations but no longer do, and 2 are sites where we conduct manufacturing operations. Investigations have been completed for 16 of the 20 sites and are in progress at 3 sites. An investigation to determine responsibility for environmental conditions is ongoing at one site.

Our policy is to accrue environmental investigation and remediation costs when it is probable that a liability has been incurred and the amount can be reasonably estimated. For sites with multiple future projected cost scenarios for identified feasible investigation and remediation options where no one estimate is more likely than all the others, our policy is to accrue the lowest estimate among the range of estimates. The measurement of the liability is based on an evaluation of currently available facts with respect to each individual situation and takes into consideration factors such as existing technology, presently enacted laws and regulations and prior experience in the remediation of similar contaminated sites. Liabilities are established for all sites based on these factors. As assessments and remediation progress at individual sites, these liabilities are reviewed periodically and adjusted to reflect additional technical data and legal information. As of December 31, 2020 and 2019, we had accrued liabilities aggregating $42.2 million and $36.0 million, respectively, for estimated future expenditures relating to environmental contingencies. These amounts have been recorded on an undiscounted basis in the Consolidated Balance Sheets. Given the uncertainties regarding the status of laws, regulations, enforcement policies, the impact of other parties potentially being fully or partially liable, technology and information related to individual sites, we do not believe it is possible to develop an estimate of the range of reasonably possible environmental loss in excess of our recorded liabilities.

During the fourth quarter of 2020, new information became available that enabled us to develop and refine estimated costs of future remediation at the following sites:

•Water Valley. EnPro Holdings has been managing trichloroethylene soil and groundwater contamination at the site in Water Valley, Mississippi in connection with the former operation in the 1970s and 1980s by a corporate predecessor of a plant located at the site, which plant was divested to BorgWarner, Inc. ("BorgWarner") in 1996. The Mississippi Department of Environmental Quality (MDEQ) issued orders against EnPro Holdings requiring evaluation of potential vapor intrusion into residential properties and commercial facilities located over the groundwater plume as well as requiring additional groundwater investigation and remediation. All of the work to be performed at the residential area, the plant and off-site is set forth in an agreed Order that we and MDEQ entered into on September 11, 2017 and we established reserves with respect to the liability associated with the anticipated remediation. Based upon then limited information regarding any incremental remediation or other actions that may be required at the site, we were unable to estimate any further loss or a reasonably possible range of loss related to this matter. During the quarter ended

40

December 31, 2020, we received the results from groundwater and vapor sampling under the plant building, which results provided a basis to estimate the costs to remediate the contamination under the building, and we received approval of the design for the remediation system to be operated in the area of contamination behind the building, which approval allowed for updating of previously estimated construction and operating and maintenance costs. Based on this information, we increased the reserve for Water Valley by $12.5 million, to $15.6 million at December 31, 2020, to reflect the minimum of a range of reasonably likely scenarios to effect the remediation of the contamination under the building and the other areas where contamination is located. The total expense related to third-party claim settlements and remediation of the Water Valley site in calendar 2020, including reserve adjustments related to remediation, was $26.5 million. Total cash payments related to third-party claim settlements and remediation at Water Valley was $20.1 million in 2020. The final selection of the remediation option and designof the remedial system to address contamination under the building is subject to MDEQ approval. We are not able at this time to estimate the upper end of a range of liability with respect to the reasonably likely scenarios to effect remediation at this site.

•Arizona Uranium Mines. EnPro Holdings has received notices from the EPA asserting that it is a potentially responsible party under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") as the successor to a former operator of eight uranium mines in Arizona. The former operator conducted operations at the mines from 1954 to 1957. In the 1990s, remediation work performed by others at these sites consisted of capping the exposed areas of the mines. We have previously reserved amounts of probable loss associated with these mines, principally including the cost of the investigative work to be conducted at such mines. We entered into an Administrative Settlement Agreement and Order on Consent for Interim Removal Action with the EPA effective November 7, 2017 for the performance of this work. The balance in these reserves as of September 30, 2020 was $1.0 million. During the quarter ended December 31, 2020, the EPA initiated group discussions with EnPro Holdings and other potentially responsible parties to resolve various technical issues, including the development of cleanup standards. Based on these discussions and subsequent discussions with other responsible parties with similar sites, we have concluded that further remedial work beyond maintenance of and minor repairs to the existing caps is probable, and we have evaluated the feasibility of various remediation scenarios. As a result, we increased the reserve for these sites by $12.9 million to $13.9 million at December 31, 2020, to reflect the low end of the range of our reasonably likely liability with respect to these sites. The expected contribution of $3.8 million from the U.S. government towards remediation of the site is considered probable and is included in other assets in the accompanying consolidated balance sheet at December 31, 2020. We are not able at this time to estimate the upper end of a range of liability with respect to these sites.

•Pine Bluff. For several years, we have been operating a groundwater remediation system at the site of an electrical transformer facility in Pine Bluff, Arkansas, which facility was sold by a corporate predecessor of EnPro Holdings in 1994. Pursuant to the terms of the sale agreement, EnPro Holdings, as the corporate successor has responsibility for pre-closing environmental conditions at the site and the existing remediation system at the site had been approved by the Arkansas Division of Environmental Quality (the “ADEQ”). During the quarter ended December 31, 2020, at the initiation of the ADEQ, we conducted further sampling and technical reviews to determine whether part of the contamination was migrating off-site that was not being captured by the existing remediation system. Based on all the sampling results received and reviewed, we concluded that modifications to the remediation program will be required. Based on this information, we increased the reserve for the Pine Bluff site by $2.8 million, to $2.8 million at December 31, 2020, to reflect the low end of the range of our reasonably likely liability with respect to this site. Total cash payments in calendar year 2020 were $0.9 million. We are not able at this time to estimate the upper end of a range of liability with respect to this site.

We believe that our accruals for specific environmental liabilities are adequate for those liabilities based on currently available information. Based upon limited information regarding any incremental remediation or other actions that may be required at these sites, we cannot estimate any further loss or a reasonably possible range of loss related to these matters. Actual costs to be incurred in future periods may vary from estimates because of the inherent uncertainties in evaluating environmental exposures due to unknown and changing conditions, changing government regulations and legal standards regarding liability.

Based on our prior ownership of Crucible Steel Corporation a/k/a Crucible, Inc. (“Crucible”), we may have additional contingent liabilities in one or more significant environmental matters. One such matter, which is included in the 20 sites referred to above, is the Lower Passaic River Study Area of the Diamond Alkali Superfund Site in New Jersey. Crucible operated a steel mill abutting the Passaic River in Harrison, New Jersey from the 1930s until 1974, which was one of many industrial operations on the river dating back to the 1800s. Certain contingent environmental liabilities related to this site were retained by a predecessor of our EnPro Holdings Inc. subsidiary (which, including its corporate predecessors is referred to as "EnPro Holdings") when it sold a majority interest in Crucible Materials Corporation (the successor of Crucible) in 1985. The United States Environmental Protection Agency (the “EPA”) notified our subsidiary in September 2003 that it is a potentially

41

responsible party (“PRP”) for Superfund response actions in the lower 17-mile stretch of the Passaic River known as the Lower Passaic River Study Area.
