ENPRO INDUSTRIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.    Overview and Basis of Presentation

Overview

EnPro Industries, Inc. (“we,” “us,” “our,” “EnPro,” or the “Company”) is a leader in designing, developing, manufacturing, servicing, and marketing proprietary engineered industrial products and serves a wide variety of customers in diverse industries around the world. Over the past several years, we have executed several strategic initiatives to change the portfolio of businesses that we operate to focus on industrial technology-related businesses with leading technologies, compelling margins, strong cash flow, and high levels of recurring revenue that serve markets with favorable secular tailwinds. These initiatives have increased our ability to provide solutions to the semiconductor, life sciences, and other technology industries.

Basis of Presentation

The accompanying interim consolidated financial statements are unaudited, and certain related information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted in accordance with Rule 10-01 of Regulation S-X. They were prepared following the same policies and procedures used in the preparation of our annual financial statements and reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of results for the periods presented. The Consolidated Balance Sheet as of December 31, 2021 was derived from the audited financial statements included in our annual report on Form 10-K for the year ended December 31, 2021. The results of operations for the interim periods are not necessarily indicative of the results for the fiscal year. These consolidated financial statements should be read in conjunction with our annual consolidated financial statements for the year ended December 31, 2021 included within our annual report on Form 10-K.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amount of assets and liabilities and the disclosures regarding contingent assets and liabilities at period end and the reported amounts of revenue and expenses during the reporting period.

All intercompany accounts and transactions between our consolidated operations have been eliminated.

2.    Acquisition

On December 17, 2021, our subsidiary, EnPro Holdings, Inc. ("EnPro Holdings"), completed the acquisition of all issued and outstanding membership interests of TCFII NxEdge LLC (“NxEdge”). Based in Boise, Idaho, NxEdge serves customers across the semiconductor supply chain, including top tier global integrated device manufacturers and original equipment manufacturers from six main facilities located in Idaho and California. With vertically integrated capabilities across the semiconductor value chain, including a robust aftermarket business, NxEdge is a leading supplier offering a set of integrated capabilities with unique processes resulting in a broad range of qualifications at top customers. NxEdge is included in our Advanced Surface Technologies segment.

The following pro forma condensed consolidated financial results of operations for EnPro are presented as if the acquisition had been completed prior to 2021:

	Three Months Ended March 31,
(in millions)	2022		2021
Pro forma net sales	$	328.7	$	322.2
Pro forma net income	$	25.2	$	22.1

These amounts have been calculated after applying our accounting policies and adjusting the results of NxEdge to reflect the additional depreciation and amortization that would have been charged assuming the fair value adjustments to inventory, property, plant and equipment and intangible assets had been applied prior to 2021 as well as additional interest expense to reflect financing required, together with the corresponding tax effects. The supplemental pro forma net income for the three months ended March 31, 2022 was adjusted to exclude $11.6 million of pre-tax costs related to the amortization of the backlog intangible asset, the amortization of the fair-value adjustment to acquisition date inventory and additional transaction-related expenses incurred during the period. These pro forma financial results have been prepared for comparative purposes only and do not reflect the effect of synergies that would have been expected to result from the integration of this acquisition. The pro

4

forma information does not purport to be indicative of the results of operations that actually would have resulted had the acquisition occurred prior to 2021, or of future results of the consolidated entities.

We continue to evaluate the purchase price allocation of this acquisition, primarily the value of certain tangible and intangible assets and the related tax impacts, and, in accordance with applicable accounting guidance, we may revise the amounts initially recognized until these estimates are final. We expect to finalize these estimates no later than the fourth quarter of 2022.

3.    Income Taxes

Our income tax expense and resulting effective tax rate are based upon the estimated annual effective tax rates applicable for the respective periods adjusted for the effect of items required to be treated as discrete in the interim periods. This estimated annual effective tax rate is affected by the relative proportions of revenue and income before taxes in the jurisdictions in which we operate. Based on the geographical mix of earnings, our annual effective tax rate fluctuates based on the portion of our profits earned in each jurisdiction.

The effective tax rates for the three months ended March 31, 2022 and 2021 were 22.3% and 22.2%, respectively. The effective tax rate for the three months ended March 31, 2022 is primarily the result of higher tax rates in most foreign jurisdictions partially offset by excess tax benefits related to share-based payment awards. The effective tax rate for the three months ended March 31, 2021 is primarily the result of higher tax rates in most foreign jurisdictions and an increase in valuation allowances related to certain net operating losses and tax attributes offset by the settlement of a state tax audit.

Total inventories	$	164.0	$	160.0

We use the last-in, first-out (“LIFO”) method of valuing certain of our inventories. An actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs, which are subject to change until the final year-end LIFO inventory valuation.

8.     Long-Term Debt

Senior Secured Credit Facilities

On December 17, 2021, we entered into a Third Amended and Restated Credit Agreement (the “Amended Credit Agreement”) among the Company and EnPro Holdings, as borrowers, certain foreign subsidiaries of the Company from time to time party thereto, as designated borrowers, the guarantors party thereto, the lenders party thereto and Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer. The Amended Credit Agreement amends, restates and replaces the Second Amended and Restated Credit Agreement dated as of June 28, 2018, as amended, among the Company and EnPro Holdings as borrowers, the guarantors party thereto, the lenders party thereto and Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer.

The Amended Credit Agreement provides for credit facilities in the initial aggregate principal amount of $1,007.5 million, consisting of a five-year, senior secured revolving credit facility of $400.0 million (the “Revolving Credit Facility”), a $142.5 million senior secured term loan facility in replacement of our existing senior secured term loan facility, maturing September 25, 2024 (the “Term Loan A-1 Facility”), a five-year, senior secured term loan facility of $315.0 million (the “Term Loan A-2 Facility”) and a 364-day, senior secured term loan facility of $150.0 million (the “364-Day Facility” and together with the Revolving Credit Facility, the Term Loan A-1 Facility and the Term Loan A-2 Facility, the “Facilities”). The Amended Credit Agreement also provides that we may seek incremental term loans and/or additional revolving credit commitments in an amount equal to the greater of $275.0 million and 100% of consolidated EBITDA 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. The Amended Credit Agreement became effective on December 17, 2021.

Initially, borrowings under the Facilities (other than the 364-Day Facility) bear interest at an annual rate of LIBOR plus 1.75% or base rate plus 0.75%, although these interest rates are subject to incremental increase or decrease based on a consolidated total net leverage ratio. Borrowings under the 364-Day Facility bear interest at an annual rate of LIBOR plus 1.50% or base rate plus 0.50%. In addition, a commitment fee accrues with respect to the unused amount of the Revolving Credit Facility at an annual rate of 0.225%, which rate is also subject to incremental increase or decrease based on a consolidated total net leverage ratio. The Amended Credit Agreement contains customary LIBOR replacement provisions.

The Term Loan A-1 Facility will amortize on a quarterly basis in an annual amount equal to 2.50% of the original principal amount of the Term Loan A-1 Facility ($150.0 million) in year one after the closing, 5.00% of such original principal amount in year two and 1.25% of such original principal amount in each of the first three quarters of year three, with the remaining outstanding principal amount payable at maturity. The Term Loan A-2 Facility will amortize on a quarterly basis in an annual amount equal to 2.5% of the original principal amount of the Term Loan A-2 Facility in each of years one through three, 5.0% 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 364-Day Facility will not amortize and will be payable in full at maturity. The Facilities are subject to prepayment with the net cash proceeds of certain asset sales, casualty or condemnation events and non-permitted debt issuances.

The Company and EnPro Holdings are the permitted borrowers under the Facilities. The Company may also from time to time designate any of its wholly owned foreign subsidiaries as a borrower under the Revolving Credit Facility. Each of the Company’s domestic subsidiaries (other than any subsidiaries that may be designated as “unrestricted” by the Company from time to time, and inactive subsidiaries) is required to guarantee the obligations of the borrowers under the Facilities, and each of the Company’s existing domestic subsidiaries (other than inactive subsidiaries) has entered into the Amended Credit Agreement to provide such a guarantee.

Borrowings under the Facilities are secured by a first-priority pledge of certain assets. The Amended Credit Agreement contains certain financial covenants and required financial ratios including a maximum consolidated total net leverage and a minimum consolidated interest coverage as defined in the Amended Credit Agreement. We were in compliance with all covenants of the Amended Credit Agreement as of March 31, 2022.

The borrowing availability under our Revolving Credit Facility at March 31, 2022 was $258.6 million after giving consideration to $11.4 million of outstanding letters of credit and $130.0 million of outstanding borrowings. The balance of our outstanding Term Loan A-1 Facility, Term Loan A-2 Facility and 364-Day Facility at March 31, 2022 was $140.6 million, $313.0 million and $150.0 million, respectively.

Senior Notes

On October 17, 2018, we completed the offering of $350.0 million aggregate principal amount of 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 $450.0 million aggregate principal amount of the outstanding 5.875% Senior Notes due 2022 (the "Old Notes").

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. 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. 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 includes covenants that restrict our ability to engage in certain activities, including incurring additional indebtedness, paying dividends and repurchasing shares of our common stock, subject in each case to specified exceptions and qualifications set forth in the indenture. The indenture further requires us to apply the net cash proceeds of certain asset sales not reinvested in acquisitions, or used to repay or otherwise reduce specified indebtedness within a specified period, in the event of the net proceeds exceeding a specified amount, to offer to repurchase the Senior Notes at a price equal to 100.0% of the principal amount thereof plus accrued and unpaid interest.

9.    Pensions

In April 2022, our board of directors declared a dividend of $0.28 per share, payable on June 15, 2022 to all shareholders of record as of June 1, 2022.

In October 2020, our board of directors authorized the expenditure of up to $50.0 million for the repurchase of our outstanding common shares through October 2022. We have not made any repurchases under this authorization.

In February 2022, we issued stock options to certain key executives for 0.1 million common shares with an exercise price of $106.54 per share. The options vest pro-rata on the first, second and third anniversaries of the grant date, subject to continued employment. No options have a term greater than 10 years.

We determine the fair value of stock options using the Black-Scholes option pricing formula as of the grant date. Key inputs into this formula include expected term, expected volatility, expected dividend yield, and the risk-free interest rate. This fair value is amortized on a straight line basis over the vesting period.

The expected term represents the period that our stock options are expected to be outstanding, and is determined based on historical experience of similar awards, given the contractual terms of the awards, vesting schedules, and expectations of future

9

employee behavior. The fair value of stock options reflects a volatility factor calculated using historical market data for EnPro's common stock. The time frame used was approximated as a six-year period from the grant date for the awards. The dividend assumption is based on our expectations as of the grant date. We base the risk-free interest rate on the yield to maturity at the time of the stock option grant on zero-coupon U.S. government bonds having a remaining life equal to the option's expected life.

The option awards issued in 2022 had a fair value of $39.07 per share at their grant date. The following assumptions were used to estimate the fair value of the 2022 option awards:

Average expected term	6 years
Expected volatility	39.88	%
Risk-free interest rate	1.89	%
Expected dividend yield	1.05	%

11.    Business Segment Information

We aggregate our operating businesses into three reportable segments. The factors considered in determining our reportable segments are the economic similarity of the businesses, the nature of products sold or services provided, the production processes and the types of customers and distribution methods. Our reportable segments are managed separately based on these differences.

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, and heavy-duty 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 create challenges for product performance.

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. It 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, 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.

We measure operating performance based on segment earnings before interest, income taxes, depreciation, amortization, and other selected items ("Adjusted Segment EBITDA"), which is segment revenue reduced by operating expenses and other costs identifiable with the segment, excluding acquisition and divestiture expenses, restructuring costs, impairment charges, non-controlling interest compensation, amortization of the fair value adjustment to acquisition date inventory, 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. Corporate expenses include general corporate administrative costs. Expenses not directly attributable to the segments, corporate expenses, net interest expense, gains and losses related to the sale of assets, and income

10

taxes are not included in the computation of Adjusted Segment EBITDA. 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 the acquisitions unless certain employment terminations have occurred.

Backlog

As of March 31, 2022, the aggregate amount of transaction price of remaining performance obligations, or backlog, on a consolidated basis was $394.1 million. Approximately 90% of these obligations are expected to be satisfied within one year. There is no certainty these orders will result in actual sales at the times or in the amounts ordered. In addition, for most of our business, this total is not particularly predictive of future performance because of our short lead times and some seasonality.

Revenue by End Market

Due to the diversified nature of our business and the wide array of products that we offer, we sell into a number of end markets. Underlying economic conditions within these markets are a major driver of our segments' sales performance. Below is a summary of our third-party sales by major end market with which we did business for the three months ended March 31, 2022 and 2021:

12.    Derivatives and Hedging

In September 2018, we entered into cross-currency swap agreements (the "Original Swap") with a notional amount of $200.0 million to manage foreign currency risk by effectively converting a portion of the interest payments related to our fixed-rate U.S. Dollar (“USD”)-denominated Senior Notes, including the semi-annual interest payments thereunder, to interest payments on fixed-rate Euro-denominated debt of 172.8 million EUR with a weighted average interest rate of 2.8%, with interest payment dates of March 15 and September 15 of each year. The Original Swap agreement matures on September 15, 2022.

In May 2019, we entered into additional cross-currency swap agreements (the "Additional Swap") with a notional amount of $100.0 million to manage an increased portion of our foreign currency risk by effectively converting a portion of the interest payments related to our fixed-rate USD-denominated Senior Notes, including the semi-annual interest payments thereunder, to interest payments on fixed-rate Euro-denominated debt of 89.6 million EUR with a weighted average interest rate of 3.5%, with interest payment dates of April 15 and October 15 of each year. The Additional Swap agreement matures on October 15, 2026.

During the term of the swap agreements, we will receive semi-annual payments from the counterparties due to the difference between the interest rate on the Senior Notes and the interest rate on the Euro debt underlying each of the swaps. There was no principal exchange at the inception of the arrangements, and there will be no exchange at maturity. At maturity (or earlier at our option), we and the counterparties will settle the swap agreements at their fair value in cash based on the aggregate notional amount and the then-applicable currency exchange rate compared to the exchange rate at the time the swap agreements were entered into.

We have designated these cross-currency swaps as qualifying hedging instruments and are accounting for them as a net investment hedge. At March 31, 2022, the fair value of the Swap and the Additional Swap equaled $10.7 million and $2.9 million and were recorded within our other current assets and other (non-current) assets, respectively, on the Consolidated Balance Sheet.The gains and losses resulting from fair value adjustments to the cross currency-swap agreements, excluding interest accruals related to the above receipts, are recorded in accumulated other comprehensive income within our cumulative foreign currency translation adjustment, as the swaps are effective in hedging the designated risk. Cash flows related to the cross-currency swaps are included in operating activities in the Consolidated Statements of Cash Flows, aside from the ultimate settlement at maturity with the counterparties, which will be included in investing activities.

13.    Fair Value Measurements

Assets and liabilities measured at fair value on a recurring basis are summarized as follows:

	Fair Value Measurements as of
	March 31, 2022		December 31, 2021
	(in millions)
Assets
Foreign currency derivatives	13.6		8.7
Deferred compensation assets	11.0		10.9
	$	24.6	$	19.6
Liabilities
Deferred compensation liabilities	$	11.6	$	11.4

Our deferred compensation assets and liabilities are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. Our foreign currency derivatives are classified as Level 2 since their value is calculated based upon observable inputs including market USD/Euro exchange rates and market interest rates.

The carrying values of our significant financial instruments reflected in the Consolidated Balance Sheets approximated their respective fair values except for the following instruments:

	March 31, 2022				December 31, 2021
	Carrying Value		Fair Value		Carrying Value		Fair Value
	(in millions)
Long-term debt	$	928.9	$	942.3	$	976.6	$	998.3

The fair values for long-term debt are based on quoted market prices for identical liabilities, but these are considered Level 2 computations because the market is not active.

14.    Accumulated Other Comprehensive Income (Loss)

Changes in accumulated other comprehensive income by component (after tax) for the three months ended March 31, 2022 are as follows:

(1)These accumulated other comprehensive income (loss) components are included in the computation of net periodic pension cost. As these are components of net periodic pension cost other than service cost, the affected Statement of Operations captions are other income (expense) (See Note 9, “Pensions"” for additional details).

15.    Commitments and 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 19 sites. At 12 of these sites, the future cost per site for us or our subsidiary is expected to exceed $100,000. Of these 19 sites, 17 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 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

15

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 and adjusted to reflect additional technical data and legal information. As of March 31, 2022 and December 31, 2021, we had accrued liabilities aggregating $46.0 million and $46.6 million, respectively, for estimated future expenditures relating to environmental contingencies. The current portion of our aggregate environmental liability at March 31, 2022 was $17.2 million. 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.

We believe that our accruals for specific environmental liabilities are adequate 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.

Lower Passaic River Study Area

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 19 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 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 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.

EnPro Holdings and approximately 70 of the numerous other PRPs, known as the Cooperating Parties Group, are parties to a May 2007 Administrative Order on Consent with the EPA to perform a Remedial Investigation/Feasibility Study (“RI/FS”) of the contaminants in the Lower Passaic River Study Area. In September 2018, EnPro Holdings withdrew from the Cooperating Parties Group but remains a party to the May 2007 Administrative Order on Consent. The RI/FS was completed and submitted to the EPA at the end of April 2015. The RI/FS recommends a targeted dredge and cap remedy with monitored natural recovery and adaptive management for the Lower Passaic River Study Area. The cost of such remedy is estimated to be $726 million. Previously, on April 11, 2014, the EPA released its Focused Feasibility Study (the “FFS”) with its proposed plan for remediating the lower eight miles of the Lower Passaic River Study Area. The FFS calls for bank-to-bank dredging and capping of the riverbed of that portion of the river and estimates a range of the present value of aggregate remediation costs of approximately $953 million to approximately $1.73 billion, although estimates of the costs and the timing of costs are inherently imprecise. On March 3, 2016, the EPA issued the final Record of Decision (ROD) as to the remedy for the lower eight miles of the Lower Passaic River Study Area, with the maximum estimated cost being reduced by the EPA from $1.73 billion to $1.38 billion, primarily due to a reduction in the amount of cubic yards of material that will be dredged. In October 2016, Occidental Chemical Corporation, the successor to the entity that operated the Diamond Alkali chemical manufacturing facility, reached an agreement with the EPA to develop the design for this proposed remedy at an estimated cost of $165 million. The EPA has estimated that it will take approximately four years to develop this design. On June 30, 2018, Occidental Chemical Corporation sued over 120 parties, including the Company, in the United States District Court for New Jersey seeking recovery of response costs under the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA").

No final allocations of responsibility have been made among the numerous PRPs that have received notices from the EPA, there are numerous identified PRPs that have not yet received PRP notices from the EPA, and there are likely many PRPs that have not yet been identified.

On April 14, 2021, the EPA issued its proposed remedy for the upper nine miles of the river, with an estimated present value cost of approximately $441 million. The proposed remedy would involve dredging and capping of the river sediment as an interim remedy followed by a period of monitoring to evaluate the response of the river system to the interim remedy.

When the EPA initiated the allocation process in 2017, it explained that a fair, carefully structured, information-based allocation was necessary to promote settlements. With the completion of the allocation process, in the second quarter of 2021

16

the EPA began settlement negotiations with the parties that participated in the allocation process, including EnPro. Our reserve for this site at March 31, 2022 was $6.6 million. Further adjustments to our reserve for this site are possible as further information is developed in the course of these discussions.

Arizona Uranium Mines

EnPro Holdings has received notices from the EPA asserting that it is a potentially responsible party under the 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. In 2020, 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. Our reserve at March 31, 2022 for this site was $13.4 million, which reflects the low end of the range of our reasonably likely liability with respect to these sites. We are not able at this time to estimate the upper end of a range of liability with respect to these sites.

On October 18, 2021, the United States District Court for the District of Arizona approved and entered a Consent Decree pursuant to which the U.S government will reimburse the Company for 35% of necessary costs of response, as defined in 42 U.S.C. section 9601(25), previously or to be in the future incurred by the Company which arise out of or in connection with releases or threatened releases of hazardous substances at or emanating from the mine sites. We expect future contributions of $3.4 million from the U.S. government towards remediation of the site. This amount was included in other assets in the accompanying consolidated balance sheet at March 31, 2022.

Except with respect to the Lower Passaic River Study Area, we are unable to estimate a reasonably possible range of loss related to any other contingent environmental liability based on our prior ownership of Crucible. See the section entitled “Crucible Steel Corporation a/k/a Crucible, Inc.” in this footnote for additional information.

Crucible Steel Corporation a/k/a Crucible, Inc.

Crucible, which was engaged primarily in the manufacture and distribution of high technology specialty metal products, was a wholly owned subsidiary of EnPro Holdings until 1983 when its assets and liabilities were distributed to a new subsidiary, Crucible Materials Corporation. EnPro Holdings sold a majority of the outstanding shares of Crucible Materials Corporation in 1985 and divested its remaining minority interest in 2004. Crucible Materials Corporation filed for Chapter 11 bankruptcy protection in May 2009 and is no longer conducting operations.

We have certain ongoing obligations, which are included in other liabilities in our Consolidated Balance Sheets, including workers’ compensation, retiree medical and other retiree benefit matters, in addition to those mentioned previously related to EnPro Holdings' period of ownership of Crucible. Based on EnPro Holdings' prior ownership of Crucible, we may have certain additional contingent liabilities, including liabilities in one or more significant environmental matters included in the matters discussed in “Environmental” above. We are investigating these matters. Except with respect to those matters for which we have an accrued liability as discussed in "Environmental" above, we are unable to estimate a reasonably possible range of loss related to these contingent liabilities.

Warranties

We provide warranties on many of our products. The specific terms and conditions of these warranties vary depending on the product and the market in which the product is sold. We record a liability based upon estimates of the costs we may incur under our warranties after a review of historical warranty experience and information about specific warranty claims. Adjustments are made to the liability as claims data, historical experience, and trends result in changes to our estimate.

17

Changes in the product warranty liability for the three months ended March 31, 2022 and 2021 are as follows:

	2022		2021
	(in millions)
Balance at beginning of year	$	4.9	$	6.7
Net charges to expense	0.3		0.5
Settlements made	(0.7)		(0.4)
Balance at end of period	$	4.5	$	6.8

Asbestos Insurance Receivables

Asbestos litigation claims against certain of our subsidiaries, including Garlock Sealing Technologies, LLC ("GST"), were resolved pursuant to the joint plan of reorganization (the "Joint Plan") filed in proceedings under Chapter 11 of the United States Bankruptcy Code that was consummated on July 29, 2017. Under the Joint Plan, GST and EnPro Holdings retained their rights to seek reimbursement under insurance policies for any amounts they have paid in the past to resolve asbestos claims, including contributions made to the asbestos claims resolution trust established under the Joint Plan (the "Trust"). These policies include a number of primary and excess general liability insurance policies that were purchased by EnPro Holdings and were in effect prior to January 1, 1976 (the “Pre-GST Coverage Block”). The policies provide coverage for “occurrences” happening during the policy periods and cover losses associated with product liability claims against EnPro Holdings and certain of its subsidiaries. Asbestos claims against GST are not covered under these policies because GST was not a subsidiary of EnPro Holdings prior to 1976. The Joint Plan provides that EnPro Holdings may retain the first $25 million of any settlements and judgments collected for non-GST asbestos claims related to insurance policies in the Pre-GST Coverage Block and EnPro Holdings and the Trust will share equally in any settlements and judgments EnPro Holdings may collect in excess of $25 million. To date, EnPro Holdings has collected almost $22 million in settlements for non-GST asbestos claims related to the Pre-GST Coverage Block and anticipates further collections once the Trust begins making claims payments on non-GST Claims. We believe that EnPro Holdings will bill, and could collect over time, as much as $10 million of insurance proceeds for non-GST asbestos claims to reimburse it for Trust payments to non-GST Trust claimants. After EnPro Holdings collects the first approximately $3 million of that coverage, remaining collections for non-GST asbestos claims from the Pre-GST Coverage Block will be shared equally with the Trust.

As of March 31, 2022, approximately $1.0 million of available products hazard limits or insurance receivables (included in Other Assets on our Consolidated Balance Sheet) existed under primary and excess general liability insurance policies other than the Pre-GST Coverage Block (the "GST Coverage Block") from solvent carriers, which we believe is available to cover contributions made to the Trust under the Joint Plan as the Trust uses those contributions to pay GST asbestos claims covered by policies in the GST Coverage Block. There are specific agreements in place with carriers regarding the remaining available coverage. We received payments of $2.2 million from an insurer in the GST Coverage Block in the first quarter of 2022.

The insurance available to cover current and future asbestos claims is from comprehensive general liability and excess liability policies that cover EnPro Holdings and certain of its other subsidiaries in addition to GST for periods prior to 1985 and therefore could be subject to potential competing claims of other covered subsidiaries and their assignees.

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following is management’s discussion and analysis of certain significant factors that have affected our financial condition, cash flows and operating results during the periods included in the accompanying unaudited consolidated financial statements and the related notes. You should read this in conjunction with those financial statements and the audited consolidated financial statements and related notes included in our annual report on Form 10-K for the fiscal year ended December 31, 2021.

Forward-Looking Information

This quarterly report on Form 10-Q includes statements that reflect projections or expectations of the future financial condition, results of operations and business of EnPro that are subject to risk and uncertainty. We believe those statements to be “forward-looking” statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. When used in this report, the words “may,” “hope,” “will,” “should,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “predict,” “potential,” “continue,” “likely,” and other expressions generally identify forward-looking statements.

We do not undertake any obligation to release publicly any revisions to these forward-looking statements to reflect events or circumstances after the date of this report or to reflect the occurrence of unanticipated events.

Non-GAAP Financial Information

In our discussion of our outlook and results of operations, we utilize financial measures that have not been prepared in conformity with generally accepted accounting principles in the United States ("GAAP"). They include adjusted net income attributable to EnPro Industries, Inc., adjusted diluted earnings per share attributable to EnPro Industries, Inc., adjusted earnings before interest, taxes, depreciation, and amortization ("adjusted EBITDA"), and total adjusted segment EBITDA. Tables showing the reconciliation of these non-GAAP financial measures to the comparable GAAP measures are included in "—Reconciliations of Non-GAAP Financial Measures to the Comparable GAAP Measures"

We believe non-GAAP metrics are commonly used financial measures for investors to evaluate our operating performance and, when read in conjunction with our consolidated financial statements, present a useful tool to evaluate our ongoing operations and performance from period to period. In addition, these non-GAAP measures are some of the factors we use in internal evaluations of the overall performance of our businesses. We acknowledge that there are many items that impact our reported results and the adjustments reflected in these non-GAAP measures are not intended to present all items that may

19

have impacted these results. In addition, the non-GAAP measures we use are not necessarily comparable to similarly titled measures used by other companies.

Overview

Overview. We design, develop, manufacture, service and market proprietary engineered industrial products. We have 19 primary manufacturing and service facilities located in 7 countries, including the United States. Over the past several years, we have executed strategic initiatives to enhance the portfolio of businesses that we operate to focus on industrial technology-related businesses with leading technologies, compelling margins, strong cash flow, and high levels of recurring revenue that serve markets with favorable secular tailwinds. These initiatives have increased our ability to provide solutions to the semiconductor, life sciences, and other technology-related 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, and heavy-duty 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 create challenges for product performance.

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, 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, 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.

COVID-19 Impacts. COVID-19 continues to significantly impact 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, have had and may 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, which may vary significantly in different regions of the world and could be impacted by new variants, the duration and terms of related governmental orders restricting activities, and the timing and pace of any economic recovery as COVID-19 impacts abate in different regions, we cannot predict with precision the extent and duration of any future changes in demand for our products and services due to COVID-19 impacts and the consequent impact on our business and financial results.

All of our primary manufacturing facilities are currently open and generally have not experienced significant supply chain disruptions. Certain operations are experiencing upstream supply chain challenges for raw materials, including certain metals and rubber-related chemicals, as raw material supply, which was reduced in response to the economic slowdown related to the COVID-19 pandemic, has not sufficiently increased to address increasing demand, including inventory restocking, as general economic activity has improved. 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

20

cannot predict if and when closures or production changes may arise as a result of implications related to the COVID-19 pandemic.  

Highlights. Financial highlights for the three months ended March 31, 2022 and 2021 are as follows:

Adjusted EBITDA 1	$	67.9	$	52.0

1 A reconciliation of non-GAAP measures to their respective GAAP measure is located in the Reconciliation of Non-GAAP Financial Measures to the Comparable GAAP Measure at the end of this section.

We delivered strong first quarter sales results driven by continued momentum in our Sealing Technologies and Advanced Surface Technologies segments, despite continued inflationary pressures and supply chain constraints. Our strong results were driven by sales growth in our semiconductor market, including the contribution of NxEdge, as well as in our heavy-duty truck, aerospace, food and pharmaceuticals markets.

Our increased Adjusted EBITDA compared to the prior-year period was driven primarily by the addition of NxEdge, operating leverage on organic sales growth and pricing initiatives, partially offset by inflationary raw material costs, rising labor expenses and the impact of divestitures completed in 2021.

In connection with our growth strategy, we will continue to evaluate making additional acquisitions to take advantage of opportunities that arise. We will 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 leading technology, compelling margins, strong cash flow, and high levels of recurring revenue that serve markets with favorable secular tailwinds.

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 revenue reduced by operating expenses and other costs identifiable with the segment, excluding acquisition and divestiture expenses, restructuring costs, impairment charges, non-controlling interest compensation, amortization of the fair value adjustment to acquisition date inventory, 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. Corporate expenses include general corporate administrative costs. Expenses not directly attributable to the segments, corporate expenses, net interest expense, gains and losses related to the sale of assets, and income taxes are not included in the computation of Adjusted Segment EBITDA. 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

22

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.

Other income (expense), net in the table above contains all items included in other (operating) expense and other income (expense) (non-operating) on our Consolidated Statements of Operations for the three months ended March 31, 2022 and 2021 with the exception of $1.4 million and $1.8 million, respectively, of restructuring costs. As noted previously, restructuring costs are excluded from Adjusted Segment EBITDA. Additionally, other income (expense), net in the table above for the three months ended March 31, 2022 and 2021 includes $(1.2) million and $0.2 million, respectively, of miscellaneous expenses (income) that are either not associated with a particular segment or not considered part of administering the corporate functions. These expenses are included in selling, general and administrative expense on our Consolidated Statements of Operations.

Three Months Ended March 31, 2022 Compared to the Three Months Ended March 31, 2021

Sales of $328.7 million in the first three months of 2022 increased 17.7% from $279.3 million in the first three months of 2021. The following table summarizes the impact of acquisitions, divestitures, and foreign currency on sales by segment:

Sales	Percent Change Three Months Ended March 31, 2022 vs. Three Months Ended March 31, 2021
increase/(decrease)	Acquisitions and Divestitures		Foreign Currency		Organic		Total
EnPro Industries, Inc.	5.8	%	(1.6)	%	13.5	%	17.7	%
Sealing Technologies	(7.3)	%	(2.0)	%	14.1	%	4.8	%
Advanced Surface Technologies	93.7	%	—	%	19.6	%	113.3	%
Engineered Materials	(30.9)	%	(2.2)	%	6.5	%	(26.6)	%

Following are the key effects of acquisitions and divestitures on sales for the first three months of 2022 compared to the same period in 2021:

•Acquisition of NxEdge (Advanced Surface Technologies) in December 2021

•Divestiture of Compressor Products International (Engineered Materials) in December 2021

•Divestiture of the polymer components business unit (Sealing Technologies), which was principally located in Houston, in September 2021

Following is a discussion of operating results for each segment during the first three months of 2022:

Sealing Technologies. Sales of $153.6 million in the first three months of 2022 reflect a 4.8% increase compared to the $146.5 million reported in the same period of 2021. Excluding the unfavorable foreign exchange translation ($2.8 million) on our 2022 sales and the sales from businesses that have since been divested ($9.3 million) from 2021 results, sales were up 14.1% or $19.3 million. This increase was driven by strong demand in heavy-duty truck, food and pharmaceutical, aerospace, and general industrial markets.

Adjusted Segment EBITDA of $33.5 million in the first three months of 2022 decreased 1.2% from $33.9 million reported in the same period of 2021. Segment AEBITDA margins for the segment decreased from 23.1% in the first three months of 2021 to 21.8% in the first three months of 2022. Excluding the unfavorable foreign exchange translation ($0.7 million) and the Segment AEBITDA earned from businesses that have since been divested ($1.7 million) from 2021 results, Adjusted Segment EBITDA increased 6.2%, or $2.0 million, to $34.3 million. The increase in Segment AEBITDA was primarily driven by higher pricing ($7.6 million) and increased sales volume, net of product mix ($4.6 million), partially offset by increased manufacturing costs ($7.0 million) mainly due to steel and other material costs increases in our heavy-duty trucking business, increased incentive compensation ($0.5 million), higher personnel costs in selling, general, and administrative costs ($2.3 million), and increased travel-related expense ($0.4 million).

Advanced Surface Technologies. Sales of $116.7 million in the first three months of 2022 reflect a 113.3% increase compared to the $54.7 million reported in the same period of 2021. While the impact of foreign exchange translation period to period was negligible for the current period, excluding the sales from a recent acquisition ($51.2 million) from the result of the first quarter of 2022, sales were up 19.6% or $10.7 million. This increase was driven primarily by stronger demand in the semiconductor market.

23

Adjusted Segment EBITDA of $34.9 million in the first three months of 2022 increased 101.7% from $17.3 million reported in the comparable period of 2021. Segment AEBITDA margins for the segment decreased from 31.6% in the first three months of 2021 to 29.9% in the first three months of 2022. While the impact of foreign exchange translation period to period was negligible for the current period, excluding the Segment AEBITDA contributed from a business recently acquired ($18.2 million) from our 2022 results, Adjusted Segment EBITDA decreased $0.6 million, or 3.5%, to $16.7 million. The decrease in Adjusted Segment EBITDA was driven by increased operating expenses supporting the development of advanced optical filter applications and growth investments in semiconductor supporting capacity expansion in both the United States and Taiwan ($5.1 million), partially offset by increased pricing ($0.9 million) and higher sales volume ($3.7 million).

Engineered Materials. Sales in the first three months of 2022 decreased 26.6% to $59.0 million from $80.4 million reported in the same period of 2021. Excluding the impact of unfavorable foreign exchange translation ($1.8 million) and the sales from a business that has since been divested ($23.2 million), sales were up 6.5% or $3.7 million, primarily due to stronger demand in general industrial, aerospace, and oil and gas markets, partially offset by a lag in automotive market as supply chain-related customer delays continue.

Adjusted Segment EBITDA in the first three months of 2022 was $9.2 million compared to Segment EBITDA of $12.6 million in the first three months of 2021, a decrease of $3.4 million, or 27.0%. Adjusted Segment EBITDA margins for the segment were 15.6%, which was a decrease from 15.7% in the first three months of 2021. Excluding the impact of unfavorable foreign exchange translation ($0.3 million) and the Segment AEBITDA contributed from a business that has since been divested ($2.7 million), Segment AEBITDA decreased $0.4 million, or 4.0%, primarily due to increased manufacturing costs driven by higher material prices ($3.0 million) offset by favorable pricing ($1.9 million) and decreased incentive compensation costs ($0.6 million).

Corporate expenses for the first three months of 2022 increased $1.8 million as compared to the same period in 2021. The increase was driven primarily by corporate restructuring charges in 2022 ($1.0 million) and increased consulting cost in support of recent acquisition and divestiture activity ($1.5 million), partially offset by lower incentive compensation costs ($1.0 million).

Interest expense, net in the first three months of 2022 increased $3.1 million from 2021 primarily due to increased outstanding debt in 2022 as a result of indebtedness incurred to fund the recent NxEdge acquisition.

Other income, net in the first three months of 2022 increased by $2.2 million as compared to other expense reported in the same period of 2021, primarily due to $1.3 million net foreign exchange gains and $1.8 million less losses on sales of businesses recorded in 2022 compared to 2021, partially offset by less pension income from non-service costs ($1.4 million)

The effective tax rates for the three months ended March 31, 2022 and 2021 were 22.3% and 22.2%, respectively. The effective tax rate for the three months ended March 31, 2022 is primarily the result of higher tax rates in most foreign jurisdictions partially offset by excess tax benefits related to share-based payment awards. The effective tax rate for the three months ended March 31, 2021 is primarily the result of higher tax rates in most foreign jurisdictions and an increase in valuation allowances related to certain net operating losses and tax attributes offset by the settlement of a state tax audit.

Net income attributable to EnPro Industries, Inc. was $16.2 million, or $0.77 per share, in the first three months of 2022 compared to net income attributable to EnPro Industries, Inc. of $18.0 million, or $0.87 per share, in the same period of 2021. Earnings per share is expressed on a diluted basis.

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. We continue to consider acquisition opportunities that align with 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. It is possible our cash requirements for one or more acquisition opportunities could exceed our available cash balance at the time of closing. Should we need additional capital, we believe we will have access to necessary resources, including the resources discussed in this section under the heading “Capital Resources.”

As of March 31, 2022, we held $277.8 million of our $293.4 million cash and cash equivalents outside of the United States. Because of the transition tax and tax on the global intangible low-taxed income provisions of the U. S. Tax Cuts and Jobs Act, undistributed earnings of our foreign subsidiaries totaling $276.2 million at March 31, 2022 have been subjected to U.S. income tax.

24

During the first quarter of 2022 we repatriated $42.9 million which was utilized to paydown our U.S.-based indebtedness and reduce our interest expense. We have targeted the repatriation of an additional $125 million by December 31, 2022 for further unscheduled paydowns of our indebtedness.

Cash Flows

Operating activities provided $30.7 million of cash in the first three months of 2022 and $20.3 million of cash in the first three months of 2021. The year-over-year increase was primarily driven by increased revenue, less cash taxes paid in the first three months of 2022, and increased insurance receipts in the first three months of 2022 related to legacy claims.

Investing activities used $3.5 million of cash in the first three months of 2022 compared to $8.3 million of cash used during the first three months of 2021. This change is driven by cash proceeds in the current quarter from the sale of businesses and less purchases of property, plant, and equipment in the first quarter of 2022.

Financing activities used $60.4 million of cash in the first three months of 2022, primarily from $47.9 million in net repayments of debt, primarily related to payments on our revolving credit facility and $5.9 million used for dividends paid. Financing activities in the first three months of 2021 used $8.1 million, primarily from $5.7 million used for dividends paid and $1.0 million in repayments of debt.

Capital Resources

Senior Secured Credit Facilities. On December 17, 2021, we entered into a Third Amended and Restated Credit Agreement (the “Amended Credit Agreement”) among the Company and EnPro Holdings, as borrowers, certain foreign subsidiaries of the Company from time to time party thereto, as designated borrowers, the guarantors party thereto, the lenders party thereto and Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer. The Amended Credit Agreement amends, restates and replaces the Second Amended and Restated Credit Agreement dated as of June 28, 2018, as amended, among the Company and EnPro Holdings as borrowers, the guarantors party thereto, the lenders party thereto and Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer.

The Amended Credit Agreement provides for credit facilities in the initial aggregate principal amount of $1,007.5 million, consisting of a five-year, senior secured revolving credit facility of $400.0 million (the “Revolving Credit Facility”), a $142.5 million senior secured term loan facility in replacement of the our existing senior secured term loan facility, maturing September 25, 2024 (the “Term Loan A-1 Facility”), a five-year, senior secured term loan facility of $315.0 million (the “Term Loan A-2 Facility”) and a 364-day, senior secured term loan facility of $150.0 million (the “364-Day Facility” and together with the Revolving Credit Facility, the Term Loan A-1 Facility and the Term Loan A-2 Facility, the “Facilities”). The Amended Credit Agreement also provides that we may seek incremental term loans and/or additional revolving credit commitments in an amount equal to the greater of $275.0 million and 100% of consolidated EBITDA for the most recently ended four-quarter period for which the we have reported financial results, plus additional amounts based on a consolidated senior secured leverage ratio. The Amended Credit Agreement became effective on December 17, 2021.

Initially, borrowings under the Facilities (other than the 364-Day Facility) bear interest at an annual rate of LIBOR plus 1.75% or base rate plus 0.75%, although these interest rates are subject to incremental increase or decrease based on a consolidated total net leverage ratio. Borrowings under the 364-Day Facility bear interest at an annual rate of LIBOR plus 1.50% or base rate plus 0.50%. In addition, a commitment fee accrues with respect to the unused amount of the Revolving Credit Facility at an annual rate of 0.225%, which rate is also subject to incremental increase or decrease based on a consolidated total net leverage ratio. The Amended Credit Agreement contains customary LIBOR replacement provisions.

The Term Loan A-1 Facility will amortize on a quarterly basis in an annual amount equal to 2.50% of the original principal amount of the Term Loan A-1 Facility ($150.0 million) in year one after the closing, 5.00% of such original principal amount in year two and 1.25% of such original principal amount in each of the first three quarters of year three, with the remaining outstanding principal amount payable at maturity. The Term Loan A-2 Facility will amortize on a quarterly basis in an annual amount equal to 2.5% of the original principal amount of the Term Loan A-2 Facility in each of years one through three, 5.0% 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 364-Day Facility will not amortize and will be payable in full at maturity. The Facilities are subject to prepayment with the net cash proceeds of certain asset sales, casualty or condemnation events and non-permitted debt issuances.

The Company and EnPro Holdings are the permitted borrowers under the Facilities. The Company may also from time to time designate any of its wholly owned foreign subsidiaries as a borrower under the Revolving Credit Facility. Each of the Company’s domestic subsidiaries (other than any subsidiaries that may be designated as “unrestricted” by the Company from

25

time to time, and inactive subsidiaries) is required to guarantee the obligations of the borrowers under the Facilities, and each of the Company’s existing domestic subsidiaries (other than inactive subsidiaries) has entered into the Amended Credit Agreement to provide such a guarantee.

The Facilities are subject to prepayment with the net cash proceeds of certain asset sales, casualty or condemnation events, and non-permitted debt issuances.

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

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

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

•substantially all of the assets (including, without limitation, machinery and equipment, inventory and other goods, accounts receivable, 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, but excluding real estate interests) of the Company and its domestic, consolidated subsidiaries (other than unrestricted or inactive subsidiaries)

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

•a maximum consolidated total net leverage ratio of not more than 4.75 to 1.0 (with total debt, for the purposes of such ratio, to be net of up to $150 million of unrestricted cash of EnPro Industries, Inc. and its consolidated subsidiaries), which ratio will decrease to 4.5 to 1.0 for each fiscal quarter beginning with the fiscal quarter ending March 31, 2022 and ending with the fiscal quarter ending December 31, 2022, and to 4.0 to 1.0 for each quarter thereafter; and, once so decrease, 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.

The Amended 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 the Amended Credit Agreement as of March 31, 2022.

The borrowing availability under our Revolving Credit Facility at March 31, 2022 was $258.6 million after giving consideration to $11.4 million of outstanding letters of credit and $130.0 million of outstanding borrowings. The balance of our outstanding Term Loan A-1 Facility, Term Loan A-2 Facility and 364-Day Facility at March 31, 2022 was $140.6 million, $313.0 million and $150.0 million, respectively.

Senior Notes. In October 2018, we completed the offering of $350.0 million aggregate principal amount of 5.75% Senior Notes due 2026 (the "Senior Notes").

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.

26

As of 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.

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.

The indenture governing the Senior Notes includes covenants that restrict our ability to engage in certain activities, including incurring additional indebtedness, paying dividends and repurchasing shares of our common stock, subject in each case to specified exceptions and qualifications set forth in the indenture.

At March 31, 2022, we were in compliance with all of the covenants of the indenture governing the Senior Notes.

Share Repurchase Program. In October 2020, our board of directors authorized the expenditure of up to $50 million for the repurchase of our outstanding common shares through October 2022. No repurchases have been made under this program.

Critical Accounting Estimates

Please refer to "Critical Accounting Estimates" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our annual report on Form 10-K for the fiscal year ended December 31, 2021, for a discussion of our critical accounting estimates, which is incorporated here by reference

Contingencies

A description of our contingencies is included in Note 15 to the Consolidated Financial Statements in this report, which is incorporated herein by reference.

Supplemental Guarantor Financial Information

On October 17, 2018, we completed the offering of the Senior Notes. The Senior Notes are fully and unconditionally guaranteed on an unsecured, unsubordinated, joint and several basis by our wholly owned direct and indirect domestic subsidiaries, that are each guarantors of our Revolving Credit Facility, including subsidiaries that were wholly owned at the time they provided the guarantee but thereafter became majority owned subsidiaries (collectively, the “Guarantor Subsidiaries”).  The Guarantor Subsidiaries at March 31, 2022 comprise all of our consolidated domestic subsidiaries at that date. Our subsidiaries organized outside of the United States (collectively, the “Non-Guarantor Subsidiaries”) do not guarantee the Senior Notes.

The Guarantor Subsidiaries jointly and severally guarantee on an unsecured, unsubordinated basis the performance and punctual payment when due, whether at stated maturity of the Senior Notes, by acceleration or otherwise, all of our obligations under the Senior Notes and the indenture governing the Senior Notes (the “Indenture”), whether for payment of principal of, premium, if any, or interest on the Senior Notes, expenses, indemnification or otherwise (all such obligations guaranteed by the Guarantor Subsidiaries are referred to as the “Guaranteed Obligations”). The Guarantor Subsidiaries have jointly and severally agreed to pay, in addition to the obligations stated above, any and all expenses (including reasonable counsel fees and expenses) incurred by the trustee (the “Trustee”) under the Indenture in enforcing any rights under their guarantees of the Guaranteed Obligations.

Each guarantee of a Guarantor Subsidiary is limited to an amount not to exceed the maximum amount that can be guaranteed by it without rendering the guarantee, as it relates to such Guarantor Subsidiary, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. Each guarantee of a Guarantor Subsidiary is a continuing guarantee and shall inure to the benefit of and be enforceable by the Trustee, the holders of the Senior Notes and their successors, transferees and assigns and, subject to the provisions described in the following sentence, remains in full force and effect until payment in full of all of the Guaranteed Obligations of such Guarantor Subsidiary and is binding upon such Guarantor Subsidiary and its successors. A guarantee of the Senior Notes by a Guarantor Subsidiary is subject to release in the following circumstances: (i) the sale, disposition, exchange or other transfer (including through merger, consolidation, amalgamation or otherwise) of the capital stock of the subsidiary made in a manner not in violation of the Indenture; (ii) the designation of the subsidiary as an “Unrestricted Subsidiary” under the Indenture; (iii) the legal defeasance or covenant defeasance of the Senior Notes in accordance with the terms of the Indenture; or (iv) the subsidiary ceasing to be our subsidiary as a result of any foreclosure of any pledge or security interest securing our Revolving Credit Facility or other exercise of remedies in respect thereof.

The following tables present summarized financial information for EnPro Industries, Inc. (the "Parent") and the Guarantor Subsidiaries on a combined basis after intercompany eliminations.

The summarized results of operations for the three months ended March 31, 2022 were as follows:

(Stated in Millions of Dollars)	Parent and Guarantor Subsidiaries
Net sales	$	222.7
Gross profit	61.5
Net loss attributable to EnPro Industries, Inc.	(4.1)
Comprehensive income attributable to EnPro Industries, Inc.	$	0.8

The summarized balance sheet at March 31, 2022 was as follows:

(Stated in Millions of Dollars)	Parent and Guarantor Subsidiaries
ASSETS
Current assets	$	286.4
Non-current assets	1,692.5
Total assets	$	1,978.9
LIABILITIES AND EQUITY

Non-current liabilities	1,131.4
Total liabilities	1,439.3
Redeemable non-controlling interests	49.3
Shareholders’ equity	490.3
Total liabilities and equity	$	1,978.9

The table above reflects $13.1 million of current intercompany receivables due to the Guarantor Subsidiaries from the Non-Guarantor Subsidiaries and $4.6 million of current intercompany payables due to the Non-Guarantor Subsidiaries from the Guarantor Subsidiaries within current assets and liabilities.

The summarized results of operations for the year ended December 31, 2021 were as follows:

(Stated in Millions of Dollars)	Parent and Guarantor Subsidiaries
Net sales	$	679.1
Gross profit	210.9
Net income attributable to EnPro Industries, Inc.	26.0
Comprehensive income attributable to EnPro Industries, Inc.	$	42.7

The summarized balance sheet at December 31, 2021 was as follows:

(Stated in Millions of Dollars)	Parent and Guarantor Subsidiaries
ASSETS
Current assets	$	286.7
Non-current assets	1,711.1
Total assets	$	1,997.8
LIABILITIES AND EQUITY
Current liabilities	$	299.9
Non-current liabilities	1,191.9
Total liabilities	1,491.8
Redeemable non-controlling interests	50.1
Shareholders’ equity	455.9
Total liabilities and equity	$	1,997.8

The table above reflects $11.2 million of current intercompany receivables due to the Guarantor Subsidiaries from the Non-Guarantor Subsidiaries and $3.2 million of current intercompany payables due to the Non-Guarantor Subsidiaries from the Guarantor Subsidiaries within current assets and liabilities.

The Senior Notes are structurally subordinated to the indebtedness and other liabilities of the Non-Guarantor Subsidiaries. The Non-Guarantor Subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due pursuant to the Senior Notes or the Indenture, or to make any funds available therefor, whether by dividends, loans, distributions or other payments. Any right that the Company or the Guarantor Subsidiaries have to receive any assets of any of the Non-Guarantor Subsidiaries upon the liquidation or reorganization of any Non-Guarantor Subsidiary, and the consequent rights of holders of Senior Notes to realize proceeds from the sale of any of a Non-Guarantor Subsidiary’s assets, would be effectively subordinated to the claims of such Non-Guarantor Subsidiary’s creditors, including trade creditors and holders of preferred equity interests, if any, of such Non-Guarantor Subsidiary. Accordingly, in the event of a bankruptcy, liquidation or reorganization of any of the Non-Guarantor Subsidiaries, the Non-Guarantor Subsidiaries will pay the holders of their debts, holders of preferred equity interests, if any, and their trade creditors before they will be able to distribute any of their assets to the Company or any Guarantor Subsidiaries.

If a Guarantor Subsidiary were to become a debtor in a case under the U.S. Bankruptcy Code or encounter other financial difficulty, under federal or state fraudulent transfer or conveyance law, a court may avoid, subordinate or otherwise decline to enforce its guarantee of the Senior Notes. A court might do so if it is found that when such Guarantor Subsidiary entered into its guarantee of the Senior Notes, or in some states when payments became due under the Senior Notes, such Guarantor Subsidiary received less than reasonably equivalent value or fair consideration and either:

•was insolvent or rendered insolvent by reason of such incurrence;

•was left with unreasonably small or otherwise inadequate capital to conduct our business; or

•believed or reasonably should have believed that it would incur debts beyond its ability to pay.

The court might also avoid the guarantee of the Senior Notes without regard to the above factors, if the court found that the Guarantor Subsidiary entered into its guarantee with actual intent to hinder, delay or defraud our creditors.

A court would likely find that a Guarantor Subsidiary did not receive reasonably equivalent value or fair consideration for its guarantee of the Senior Notes, if such Guarantor Subsidiary did not substantially benefit directly or indirectly from the funding made available by the issuance of the Senior Notes. If a court were to avoid a guarantee of the Senior Notes provided by a Guarantor Subsidiary, holders of the Senior Notes would no longer have any claim against such Guarantor Subsidiary. The measures of insolvency for purposes of these fraudulent transfer or conveyance laws will vary depending upon the law applied in any proceeding to determine whether a fraudulent transfer or conveyance has occurred, such that we cannot predict what standards a court would use to determine whether or not a Guarantor Subsidiary was solvent at the relevant time or, regardless of the standard that a court uses, that the guarantee of a Guarantor Subsidiary would not be subordinated to such Guarantor Subsidiary’s other debt. As noted above, each guarantee provided by a Guarantor Subsidiary includes a provision intended to limit the Guarantor Subsidiary’s liability to the maximum amount that it could incur without causing the incurrence of

29

obligations under its guarantee to be a fraudulent transfer or conveyance. This provision may not be effective to protect those guarantees from being avoided under fraudulent transfer or conveyance law, or it may reduce that Guarantor Subsidiary’s obligation to an amount that effectively makes its guarantee worthless, and we cannot predict whether a court will ultimately find it to be effective.

On the basis of historical financial information, operating history and other factors, we believe that each of the Guarantor Subsidiaries, after giving effect to the issuance of its guarantee of the Senior Notes when such guarantee was issued, was not insolvent, did not have unreasonably small capital for the business in which it engaged and did not and has not incurred debts beyond its ability to pay such debts as they mature. We cannot assure you, however, as to what standard a court would apply in making these determinations or that a court would agree with our conclusions in this regard.

Reconciliations of Non-GAAP Financial Measures to the Comparable GAAP Measures

We believe that it would be helpful to the readers of the financial statements to understand the impact of certain selected items on our reported net income attributable to EnPro Industries, Inc., diluted earnings per share attributable to EnPro Industries, Inc., and total adjusted segment EBITDA, including items that may recur from time to time. The items adjusted for in these non-GAAP financial measures are those that are excluded by management in budgeting or projecting for performance in future periods, as they typically relate to events specific to the period in which they occur. Accordingly, these are some of the factors the company uses in internal evaluations of the overall performance of its businesses. In addition, management believes these non-GAAP financial measures are commonly used financial measures for investors to evaluate the company’s operating performance and, when read in conjunction with the company’s consolidated financial statements, present a useful tool to evaluate the company’s ongoing operations and performance from period to period. Management acknowledges that there are many items that impact a company’s reported results and the adjustments reflected in these non-GAAP financial measures are not intended to present all items that may have impacted these results. In addition, these non-GAAP measures are not necessarily comparable to similarly titled measures used by other companies.

The following presents a reconciliation of (i) net income attributable to EnPro Industries, Inc. to adjusted net income attributable to EnPro Industries, Inc. and adjusted diluted earnings per share and (ii) net income attributable to EnPro Industries, Inc. to adjusted EBITDA for the three months ended March 31, 2022 and 2021.

1 Adjusted diluted earnings per share attributable to EnPro Industries, Inc. Per share amounts were calculated by dividing by the weighted-average shares of diluted common stock outstanding during the periods.

2 Non-controlling interest compensation allocation represents compensation expense associated with a portion of the rollover equity from the acquisitions of LeanTeq and Alluxa that is subject to reduction for certain types of employment terminations of the LeanTeq and Alluxa sellers and is directly related to the terms of the respective acquisitions. This expense will continue to be recognized as compensation expense over the term of the put and call options associated with the acquisitions unless certain employment terminations have occurred.

3Other adjustments are included in selling, general, and administrative, cost of sales, and other operating expenses on the consolidated statements of operations.

Item 3.     Quantitative and Qualitative Disclosures About Market Risk

We are exposed to certain market risks as part of our ongoing business operations, including risks from changes in foreign currency exchange rates and interest rates that could impact our financial condition, results of operations and cash flows. We manage our exposure to these and other market risks through regular operating and financing activities and through the use of derivative financial instruments. We intend to use derivative financial instruments as risk management tools and not for speculative investment purposes. For information about our interest rate risk, see “Quantitative and Qualitative Disclosures about Market Risk – Interest Rate Risk” in our annual report on Form 10-K for the year ended December 31, 2021.

Foreign Currency Risk

We are exposed to foreign currency risks that arise from normal business operations. These risks include the translation of local currency balances of our foreign subsidiaries, intercompany loans with foreign subsidiaries and transactions denominated in foreign currencies. Our objective is to control our exposure to these risks and limit the volatility in our reported earnings due to foreign currency fluctuations through our normal operating activities and, where appropriate, through foreign currency forward contracts and option contracts. The notional amount of foreign exchange contracts hedging foreign currency transactions was $3.8 million and $3.3 million at March 31, 2022 and December 31, 2021, respectively.

32

In September 2018, we entered into cross-currency swap agreements with a notional amount of $200.0 million to manage foreign currency risk by effectively converting a portion of the interest payments related to our fixed-rate U.S. Dollar (“USD”)-denominated Senior Notes, including the semi-annual interest payments thereunder, to interest payments on fixed-rate Euro-denominated debt of 172.8 million EUR with a weighted average interest rate of 2.8%, with interest payment dates of March 15 and September 15 of each year. The swap agreement matures on September 15, 2022.

In May 2019, we entered into additional cross-currency swap agreements with a notional amount of $100.0 million to manage foreign currency risk by effectively converting a portion of the interest payments related to our fixed-rate USD-denominated Senior Notes, including the semi-annual interest payments thereunder, to interest payments on fixed-rate Euro-denominated debt of 89.6 million EUR with a weighted average interest rate of 3.5% , with interest payment dates of April 15 and October 15 of each year. The swap agreement matures on October 15, 2026.

During the term of the swap agreements, we will receive semi-annual payments from the counterparties due to the difference between the interest rate on the Senior Notes and the interest rate on the Euro debt underlying the swap. There was no principal exchange at the inception of the arrangements, and there will be no exchange at maturity. At maturity (or earlier at our option), we and the counterparties will settle the swap agreements at their fair value in cash based on the aggregate notional amount and the then-applicable currency exchange rate compared to the exchange rate at the time the swap agreements were entered into.

Commodity Risk

We source a wide variety of materials and components from a network of global suppliers. While such materials are typically available from numerous suppliers, commodity raw materials such as steel, engineered plastics, copper and polymers, are subject to price fluctuations (including increases due to new or increased tariffs), which could have a negative impact on our results. The impacts from the COVID-19 pandemic and geopolitical variables could further increase the risk of supply, pricing, and demand of necessary raw materials as well as drive further fluctuations in energy and natural gas costs. We strive to pass along commodity price increases to customers to avoid profit margin erosion and utilize lean initiatives to further mitigate the impact of commodity raw material price fluctuations as we achieve improved efficiencies. We do not hedge commodity risk with any market risk sensitive instruments.

Item 4.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)). The purpose of our disclosure controls and procedures is to provide reasonable assurance that information required to be disclosed in our reports filed under the Exchange Act, including this report, is recorded, processed, summarized and reported within the time periods specified, and that such information is accumulated and communicated to our management to allow timely decisions regarding disclosure.

Based on the controls evaluation, our chief executive officer and chief financial officer have concluded that our disclosure controls and procedures are effective to reasonably ensure that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified, and that management will be timely alerted to material information required to be included in our periodic reports filed with the Securities and Exchange Commission.

In addition, no change in our internal control over financial reporting has occurred during the quarter ended March 31, 2022, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II

OTHER INFORMATION

 Item 1.    Legal Proceedings.

A description of environmental and other legal matters is included in Note 15 to the Consolidated Financial Statements in this report, which is incorporated herein by reference. In addition to the matters noted and discussed in those sections of this report, 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 that 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.

Item 2.    Unregistered Sales of Equity Securities and Use of Proceeds.

The following table sets forth all purchases made by or on behalf of the Company or any “affiliated purchaser,” as defined in Rule 10b-18(a)(3) under the Exchange Act, of shares of our common stock during each month in the first quarter of 2022.

Period	(a) Total Number of Shares (or Units) Purchased		(b) Average Price Paid per Share (or Unit)			(c) Total Number of Shares (or Units) Purchased as Part  of Publicly Announced Plans or Programs	(d) Maximum Number (or Approximate Dollar Value) of Shares (or  Units) That May Yet Be Purchased Under the Plans or Programs
January 1 - January 31, 2022	—		—			—	$50,000,000	(1)

Total	319	(2)	$	99.71	(2)	—	$50,000,000	(1)

(1)In October of 2020, our board of directors authorized an expenditure program of up to $50.0 million for the repurchase of our outstanding common shares through October 2022. We have not made any repurchases under this authorization.

(2)In March 2022, a total of 319 shares were transferred to a rabbi trust that we established in connection with our Deferred Compensation Plan for Non-Employee Directors, pursuant to which non-employee directors may elect to defer directors’ fees into common stock units. EnPro Holdings furnished these shares in exchange for management and other services provided by EnPro. Of these shares, 72 shares were valued at a price of $106.51 per share, the closing trading price of our common stock on March 16, 2022, and 247 of these shares were valued at a price of $97.73 per share, the closing trading price of our common stock on March 31, 2022. Accordingly, the total 319 shares were valued at a weighted average price of $99.71. We do not consider the transfer of shares from EnPro Holdings in this context to be pursuant to a publicly announced plan or program.

Overview and Basis of Presentation

Overview and Basis of Presentation

Overview

EnPro Industries, Inc. (“we,” “us,” “our,” “EnPro,” or the “Company”) is a leader in designing, developing, manufacturing, servicing, and marketing proprietary engineered industrial products and serves a wide variety of customers in diverse industries around the world. Over the past several years, we have executed several strategic initiatives to change the portfolio of businesses that we operate to focus on industrial technology-related businesses with leading technologies, compelling margins, strong cash flow, and high levels of recurring revenue that serve markets with favorable secular tailwinds. These initiatives have increased our ability to provide solutions to the semiconductor, life sciences, and other technology industries.

Basis of Presentation

The accompanying interim consolidated financial statements are unaudited, and certain related information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted in accordance with Rule 10-01 of Regulation S-X. They were prepared following the same policies and procedures used in the preparation of our annual financial statements and reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of results for the periods presented. The Consolidated Balance Sheet as of December 31, 2021 was derived from the audited financial statements included in our annual report on Form 10-K for the year ended December 31, 2021. The results of operations for the interim periods are not necessarily indicative of the results for the fiscal year. These consolidated financial statements should be read in conjunction with our annual consolidated financial statements for the year ended December 31, 2021 included within our annual report on Form 10-K.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amount of assets and liabilities and the disclosures regarding contingent assets and liabilities at period end and the reported amounts of revenue and expenses during the reporting period.

All intercompany accounts and transactions between our consolidated operations have been eliminated.

Business Combination and Asset Acquisition [Abstract]

Acquisition

Acquisition

On December 17, 2021, our subsidiary, EnPro Holdings, Inc. ("EnPro Holdings"), completed the acquisition of all issued and outstanding membership interests of TCFII NxEdge LLC (“NxEdge”). Based in Boise, Idaho, NxEdge serves customers across the semiconductor supply chain, including top tier global integrated device manufacturers and original equipment manufacturers from six main facilities located in Idaho and California. With vertically integrated capabilities across the semiconductor value chain, including a robust aftermarket business, NxEdge is a leading supplier offering a set of integrated capabilities with unique processes resulting in a broad range of qualifications at top customers. NxEdge is included in our Advanced Surface Technologies segment.

The following pro forma condensed consolidated financial results of operations for EnPro are presented as if the acquisition had been completed prior to 2021:

	Three Months Ended March 31,
(in millions)	2022		2021
Pro forma net sales	$	328.7	$	322.2
Pro forma net income	$	25.2	$	22.1

These amounts have been calculated after applying our accounting policies and adjusting the results of NxEdge to reflect the additional depreciation and amortization that would have been charged assuming the fair value adjustments to inventory, property, plant and equipment and intangible assets had been applied prior to 2021 as well as additional interest expense to reflect financing required, together with the corresponding tax effects. The supplemental pro forma net income for the three months ended March 31, 2022 was adjusted to exclude $11.6 million of pre-tax costs related to the amortization of the backlog intangible asset, the amortization of the fair-value adjustment to acquisition date inventory and additional transaction-related expenses incurred during the period. These pro forma financial results have been prepared for comparative purposes only and do not reflect the effect of synergies that would have been expected to result from the integration of this acquisition. The pro

forma information does not purport to be indicative of the results of operations that actually would have resulted had the acquisition occurred prior to 2021, or of future results of the consolidated entities.We continue to evaluate the purchase price allocation of this acquisition, primarily the value of certain tangible and intangible assets and the related tax impacts, and, in accordance with applicable accounting guidance, we may revise the amounts initially recognized until these estimates are final. We expect to finalize these estimates no later than the fourth quarter of 2022.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

Our income tax expense and resulting effective tax rate are based upon the estimated annual effective tax rates applicable for the respective periods adjusted for the effect of items required to be treated as discrete in the interim periods. This estimated annual effective tax rate is affected by the relative proportions of revenue and income before taxes in the jurisdictions in which we operate. Based on the geographical mix of earnings, our annual effective tax rate fluctuates based on the portion of our profits earned in each jurisdiction.

The effective tax rates for the three months ended March 31, 2022 and 2021 were 22.3% and 22.2%, respectively. The effective tax rate for the three months ended March 31, 2022 is primarily the result of higher tax rates in most foreign jurisdictions partially offset by excess tax benefits related to share-based payment awards. The effective tax rate for the three months ended March 31, 2021 is primarily the result of higher tax rates in most foreign jurisdictions and an increase in valuation allowances related to certain net operating losses and tax attributes offset by the settlement of a state tax audit.

We use the last-in, first-out (“LIFO”) method of valuing certain of our inventories. An actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs, which are subject to change until the final year-end LIFO inventory valuation.

Long-Term Debt

Senior Secured Credit Facilities

On December 17, 2021, we entered into a Third Amended and Restated Credit Agreement (the “Amended Credit Agreement”) among the Company and EnPro Holdings, as borrowers, certain foreign subsidiaries of the Company from time to time party thereto, as designated borrowers, the guarantors party thereto, the lenders party thereto and Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer. The Amended Credit Agreement amends, restates and replaces the Second Amended and Restated Credit Agreement dated as of June 28, 2018, as amended, among the Company and EnPro Holdings as borrowers, the guarantors party thereto, the lenders party thereto and Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer.

The Amended Credit Agreement provides for credit facilities in the initial aggregate principal amount of $1,007.5 million, consisting of a five-year, senior secured revolving credit facility of $400.0 million (the “Revolving Credit Facility”), a $142.5 million senior secured term loan facility in replacement of our existing senior secured term loan facility, maturing September 25, 2024 (the “Term Loan A-1 Facility”), a five-year, senior secured term loan facility of $315.0 million (the “Term Loan A-2 Facility”) and a 364-day, senior secured term loan facility of $150.0 million (the “364-Day Facility” and together with the Revolving Credit Facility, the Term Loan A-1 Facility and the Term Loan A-2 Facility, the “Facilities”). The Amended Credit Agreement also provides that we may seek incremental term loans and/or additional revolving credit commitments in an amount equal to the greater of $275.0 million and 100% of consolidated EBITDA 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. The Amended Credit Agreement became effective on December 17, 2021.

Initially, borrowings under the Facilities (other than the 364-Day Facility) bear interest at an annual rate of LIBOR plus 1.75% or base rate plus 0.75%, although these interest rates are subject to incremental increase or decrease based on a consolidated total net leverage ratio. Borrowings under the 364-Day Facility bear interest at an annual rate of LIBOR plus 1.50% or base rate plus 0.50%. In addition, a commitment fee accrues with respect to the unused amount of the Revolving Credit Facility at an annual rate of 0.225%, which rate is also subject to incremental increase or decrease based on a consolidated total net leverage ratio. The Amended Credit Agreement contains customary LIBOR replacement provisions.

The Term Loan A-1 Facility will amortize on a quarterly basis in an annual amount equal to 2.50% of the original principal amount of the Term Loan A-1 Facility ($150.0 million) in year one after the closing, 5.00% of such original principal amount in year two and 1.25% of such original principal amount in each of the first three quarters of year three, with the remaining outstanding principal amount payable at maturity. The Term Loan A-2 Facility will amortize on a quarterly basis in an annual amount equal to 2.5% of the original principal amount of the Term Loan A-2 Facility in each of years one through three, 5.0% 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 364-Day Facility will not amortize and will be payable in full at maturity. The Facilities are subject to prepayment with the net cash proceeds of certain asset sales, casualty or condemnation events and non-permitted debt issuances.

The Company and EnPro Holdings are the permitted borrowers under the Facilities. The Company may also from time to time designate any of its wholly owned foreign subsidiaries as a borrower under the Revolving Credit Facility. Each of the Company’s domestic subsidiaries (other than any subsidiaries that may be designated as “unrestricted” by the Company from time to time, and inactive subsidiaries) is required to guarantee the obligations of the borrowers under the Facilities, and each of the Company’s existing domestic subsidiaries (other than inactive subsidiaries) has entered into the Amended Credit Agreement to provide such a guarantee.

Borrowings under the Facilities are secured by a first-priority pledge of certain assets. The Amended Credit Agreement contains certain financial covenants and required financial ratios including a maximum consolidated total net leverage and a minimum consolidated interest coverage as defined in the Amended Credit Agreement. We were in compliance with all covenants of the Amended Credit Agreement as of March 31, 2022.

The borrowing availability under our Revolving Credit Facility at March 31, 2022 was $258.6 million after giving consideration to $11.4 million of outstanding letters of credit and $130.0 million of outstanding borrowings. The balance of our outstanding Term Loan A-1 Facility, Term Loan A-2 Facility and 364-Day Facility at March 31, 2022 was $140.6 million, $313.0 million and $150.0 million, respectively.

Senior Notes

On October 17, 2018, we completed the offering of $350.0 million aggregate principal amount of 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 $450.0 million aggregate principal amount of the outstanding 5.875% Senior Notes due 2022 (the "Old Notes").

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. 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. 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 includes covenants that restrict our ability to engage in certain activities, including incurring additional indebtedness, paying dividends and repurchasing shares of our common stock, subject in each case to specified exceptions and qualifications set forth in the indenture. The indenture further requires us to apply the net cash proceeds of certain asset sales not reinvested in acquisitions, or used to repay or otherwise reduce specified indebtedness within a specified period, in the event of the net proceeds exceeding a specified amount, to offer to repurchase the Senior Notes at a price equal to 100.0% of the principal amount thereof plus accrued and unpaid interest.

We intend to declare regular quarterly cash dividends on our common stock, as determined by our board of directors, after taking into account our current and projected cash flows, earnings, financial position, debt covenants and other relevant factors. In accordance with the board of directors' declaration, total dividend payments of $5.9 million were made during the three months ended March 31, 2022.

In April 2022, our board of directors declared a dividend of $0.28 per share, payable on June 15, 2022 to all shareholders of record as of June 1, 2022.

In October 2020, our board of directors authorized the expenditure of up to $50.0 million for the repurchase of our outstanding common shares through October 2022. We have not made any repurchases under this authorization.

In February 2022, we issued stock options to certain key executives for 0.1 million common shares with an exercise price of $106.54 per share. The options vest pro-rata on the first, second and third anniversaries of the grant date, subject to continued employment. No options have a term greater than 10 years.

We determine the fair value of stock options using the Black-Scholes option pricing formula as of the grant date. Key inputs into this formula include expected term, expected volatility, expected dividend yield, and the risk-free interest rate. This fair value is amortized on a straight line basis over the vesting period.

The expected term represents the period that our stock options are expected to be outstanding, and is determined based on historical experience of similar awards, given the contractual terms of the awards, vesting schedules, and expectations of future

employee behavior. The fair value of stock options reflects a volatility factor calculated using historical market data for EnPro's common stock. The time frame used was approximated as a six-year period from the grant date for the awards. The dividend assumption is based on our expectations as of the grant date. We base the risk-free interest rate on the yield to maturity at the time of the stock option grant on zero-coupon U.S. government bonds having a remaining life equal to the option's expected life.

The option awards issued in 2022 had a fair value of $39.07 per share at their grant date. The following assumptions were used to estimate the fair value of the 2022 option awards:

Average expected term	6 years
Expected volatility	39.88	%
Risk-free interest rate	1.89	%
Expected dividend yield	1.05	%

Segment Reporting [Abstract]

Business Segment Information

Business Segment Information

We aggregate our operating businesses into three reportable segments. The factors considered in determining our reportable segments are the economic similarity of the businesses, the nature of products sold or services provided, the production processes and the types of customers and distribution methods. Our reportable segments are managed separately based on these differences.

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, and heavy-duty 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 create challenges for product performance.

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. It 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, 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.

We measure operating performance based on segment earnings before interest, income taxes, depreciation, amortization, and other selected items ("Adjusted Segment EBITDA"), which is segment revenue reduced by operating expenses and other costs identifiable with the segment, excluding acquisition and divestiture expenses, restructuring costs, impairment charges, non-controlling interest compensation, amortization of the fair value adjustment to acquisition date inventory, 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. Corporate expenses include general corporate administrative costs. Expenses not directly attributable to the segments, corporate expenses, net interest expense, gains and losses related to the sale of assets, and income

taxes are not included in the computation of Adjusted Segment EBITDA. 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 the acquisitions unless certain employment terminations have occurred.

Backlog

As of March 31, 2022, the aggregate amount of transaction price of remaining performance obligations, or backlog, on a consolidated basis was $394.1 million. Approximately 90% of these obligations are expected to be satisfied within one year. There is no certainty these orders will result in actual sales at the times or in the amounts ordered. In addition, for most of our business, this total is not particularly predictive of future performance because of our short lead times and some seasonality.

Revenue by End Market

Due to the diversified nature of our business and the wide array of products that we offer, we sell into a number of end markets. Underlying economic conditions within these markets are a major driver of our segments' sales performance. Below is a summary of our third-party sales by major end market with which we did business for the three months ended March 31, 2022 and 2021:

Derivatives and Hedging

Derivatives and Hedging

In September 2018, we entered into cross-currency swap agreements (the "Original Swap") with a notional amount of $200.0 million to manage foreign currency risk by effectively converting a portion of the interest payments related to our fixed-rate U.S. Dollar (“USD”)-denominated Senior Notes, including the semi-annual interest payments thereunder, to interest payments on fixed-rate Euro-denominated debt of 172.8 million EUR with a weighted average interest rate of 2.8%, with interest payment dates of March 15 and September 15 of each year. The Original Swap agreement matures on September 15, 2022.

In May 2019, we entered into additional cross-currency swap agreements (the "Additional Swap") with a notional amount of $100.0 million to manage an increased portion of our foreign currency risk by effectively converting a portion of the interest payments related to our fixed-rate USD-denominated Senior Notes, including the semi-annual interest payments thereunder, to interest payments on fixed-rate Euro-denominated debt of 89.6 million EUR with a weighted average interest rate of 3.5%, with interest payment dates of April 15 and October 15 of each year. The Additional Swap agreement matures on October 15, 2026.

During the term of the swap agreements, we will receive semi-annual payments from the counterparties due to the difference between the interest rate on the Senior Notes and the interest rate on the Euro debt underlying each of the swaps. There was no principal exchange at the inception of the arrangements, and there will be no exchange at maturity. At maturity (or earlier at our option), we and the counterparties will settle the swap agreements at their fair value in cash based on the aggregate notional amount and the then-applicable currency exchange rate compared to the exchange rate at the time the swap agreements were entered into.

We have designated these cross-currency swaps as qualifying hedging instruments and are accounting for them as a net investment hedge. At March 31, 2022, the fair value of the Swap and the Additional Swap equaled $10.7 million and $2.9 million and were recorded within our other current assets and other (non-current) assets, respectively, on the Consolidated Balance Sheet.The gains and losses resulting from fair value adjustments to the cross currency-swap agreements, excluding interest accruals related to the above receipts, are recorded in accumulated other comprehensive income within our cumulative foreign currency translation adjustment, as the swaps are effective in hedging the designated risk. Cash flows related to the cross-currency swaps are included in operating activities in the Consolidated Statements of Cash Flows, aside from the ultimate settlement at maturity with the counterparties, which will be included in investing activities.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and 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 19 sites. At 12 of these sites, the future cost per site for us or our subsidiary is expected to exceed $100,000. Of these 19 sites, 17 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 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 and adjusted to reflect additional technical data and legal information. As of March 31, 2022 and December 31, 2021, we had accrued liabilities aggregating $46.0 million and $46.6 million, respectively, for estimated future expenditures relating to environmental contingencies. The current portion of our aggregate environmental liability at March 31, 2022 was $17.2 million. 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.

We believe that our accruals for specific environmental liabilities are adequate 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.

Lower Passaic River Study Area

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 19 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 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 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.

EnPro Holdings and approximately 70 of the numerous other PRPs, known as the Cooperating Parties Group, are parties to a May 2007 Administrative Order on Consent with the EPA to perform a Remedial Investigation/Feasibility Study (“RI/FS”) of the contaminants in the Lower Passaic River Study Area. In September 2018, EnPro Holdings withdrew from the Cooperating Parties Group but remains a party to the May 2007 Administrative Order on Consent. The RI/FS was completed and submitted to the EPA at the end of April 2015. The RI/FS recommends a targeted dredge and cap remedy with monitored natural recovery and adaptive management for the Lower Passaic River Study Area. The cost of such remedy is estimated to be $726 million. Previously, on April 11, 2014, the EPA released its Focused Feasibility Study (the “FFS”) with its proposed plan for remediating the lower eight miles of the Lower Passaic River Study Area. The FFS calls for bank-to-bank dredging and capping of the riverbed of that portion of the river and estimates a range of the present value of aggregate remediation costs of approximately $953 million to approximately $1.73 billion, although estimates of the costs and the timing of costs are inherently imprecise. On March 3, 2016, the EPA issued the final Record of Decision (ROD) as to the remedy for the lower eight miles of the Lower Passaic River Study Area, with the maximum estimated cost being reduced by the EPA from $1.73 billion to $1.38 billion, primarily due to a reduction in the amount of cubic yards of material that will be dredged. In October 2016, Occidental Chemical Corporation, the successor to the entity that operated the Diamond Alkali chemical manufacturing facility, reached an agreement with the EPA to develop the design for this proposed remedy at an estimated cost of $165 million. The EPA has estimated that it will take approximately four years to develop this design. On June 30, 2018, Occidental Chemical Corporation sued over 120 parties, including the Company, in the United States District Court for New Jersey seeking recovery of response costs under the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA").

No final allocations of responsibility have been made among the numerous PRPs that have received notices from the EPA, there are numerous identified PRPs that have not yet received PRP notices from the EPA, and there are likely many PRPs that have not yet been identified.

On April 14, 2021, the EPA issued its proposed remedy for the upper nine miles of the river, with an estimated present value cost of approximately $441 million. The proposed remedy would involve dredging and capping of the river sediment as an interim remedy followed by a period of monitoring to evaluate the response of the river system to the interim remedy.

When the EPA initiated the allocation process in 2017, it explained that a fair, carefully structured, information-based allocation was necessary to promote settlements. With the completion of the allocation process, in the second quarter of 2021

the EPA began settlement negotiations with the parties that participated in the allocation process, including EnPro. Our reserve for this site at March 31, 2022 was $6.6 million. Further adjustments to our reserve for this site are possible as further information is developed in the course of these discussions.

Arizona Uranium Mines

EnPro Holdings has received notices from the EPA asserting that it is a potentially responsible party under the 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. In 2020, 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. Our reserve at March 31, 2022 for this site was $13.4 million, which reflects the low end of the range of our reasonably likely liability with respect to these sites. We are not able at this time to estimate the upper end of a range of liability with respect to these sites.

On October 18, 2021, the United States District Court for the District of Arizona approved and entered a Consent Decree pursuant to which the U.S government will reimburse the Company for 35% of necessary costs of response, as defined in 42 U.S.C. section 9601(25), previously or to be in the future incurred by the Company which arise out of or in connection with releases or threatened releases of hazardous substances at or emanating from the mine sites. We expect future contributions of $3.4 million from the U.S. government towards remediation of the site. This amount was included in other assets in the accompanying consolidated balance sheet at March 31, 2022.

Except with respect to the Lower Passaic River Study Area, we are unable to estimate a reasonably possible range of loss related to any other contingent environmental liability based on our prior ownership of Crucible. See the section entitled “Crucible Steel Corporation a/k/a Crucible, Inc.” in this footnote for additional information.

Crucible, which was engaged primarily in the manufacture and distribution of high technology specialty metal products, was a wholly owned subsidiary of EnPro Holdings until 1983 when its assets and liabilities were distributed to a new subsidiary, Crucible Materials Corporation. EnPro Holdings sold a majority of the outstanding shares of Crucible Materials Corporation in 1985 and divested its remaining minority interest in 2004. Crucible Materials Corporation filed for Chapter 11 bankruptcy protection in May 2009 and is no longer conducting operations.

We have certain ongoing obligations, which are included in other liabilities in our Consolidated Balance Sheets, including workers’ compensation, retiree medical and other retiree benefit matters, in addition to those mentioned previously related to EnPro Holdings' period of ownership of Crucible. Based on EnPro Holdings' prior ownership of Crucible, we may have certain additional contingent liabilities, including liabilities in one or more significant environmental matters included in the matters discussed in “Environmental” above. We are investigating these matters. Except with respect to those matters for which we have an accrued liability as discussed in "Environmental" above, we are unable to estimate a reasonably possible range of loss related to these contingent liabilities.

Warranties

We provide warranties on many of our products. The specific terms and conditions of these warranties vary depending on the product and the market in which the product is sold. We record a liability based upon estimates of the costs we may incur under our warranties after a review of historical warranty experience and information about specific warranty claims. Adjustments are made to the liability as claims data, historical experience, and trends result in changes to our estimate.

Changes in the product warranty liability for the three months ended March 31, 2022 and 2021 are as follows:

	2022		2021
	(in millions)
Balance at beginning of year	$	4.9	$	6.7
Net charges to expense	0.3		0.5
Settlements made	(0.7)		(0.4)
Balance at end of period	$	4.5	$	6.8

Asbestos Insurance Receivables

Asbestos litigation claims against certain of our subsidiaries, including Garlock Sealing Technologies, LLC ("GST"), were resolved pursuant to the joint plan of reorganization (the "Joint Plan") filed in proceedings under Chapter 11 of the United States Bankruptcy Code that was consummated on July 29, 2017. Under the Joint Plan, GST and EnPro Holdings retained their rights to seek reimbursement under insurance policies for any amounts they have paid in the past to resolve asbestos claims, including contributions made to the asbestos claims resolution trust established under the Joint Plan (the "Trust"). These policies include a number of primary and excess general liability insurance policies that were purchased by EnPro Holdings and were in effect prior to January 1, 1976 (the “Pre-GST Coverage Block”). The policies provide coverage for “occurrences” happening during the policy periods and cover losses associated with product liability claims against EnPro Holdings and certain of its subsidiaries. Asbestos claims against GST are not covered under these policies because GST was not a subsidiary of EnPro Holdings prior to 1976. The Joint Plan provides that EnPro Holdings may retain the first $25 million of any settlements and judgments collected for non-GST asbestos claims related to insurance policies in the Pre-GST Coverage Block and EnPro Holdings and the Trust will share equally in any settlements and judgments EnPro Holdings may collect in excess of $25 million. To date, EnPro Holdings has collected almost $22 million in settlements for non-GST asbestos claims related to the Pre-GST Coverage Block and anticipates further collections once the Trust begins making claims payments on non-GST Claims. We believe that EnPro Holdings will bill, and could collect over time, as much as $10 million of insurance proceeds for non-GST asbestos claims to reimburse it for Trust payments to non-GST Trust claimants. After EnPro Holdings collects the first approximately $3 million of that coverage, remaining collections for non-GST asbestos claims from the Pre-GST Coverage Block will be shared equally with the Trust.

As of March 31, 2022, approximately $1.0 million of available products hazard limits or insurance receivables (included in Other Assets on our Consolidated Balance Sheet) existed under primary and excess general liability insurance policies other than the Pre-GST Coverage Block (the "GST Coverage Block") from solvent carriers, which we believe is available to cover contributions made to the Trust under the Joint Plan as the Trust uses those contributions to pay GST asbestos claims covered by policies in the GST Coverage Block. There are specific agreements in place with carriers regarding the remaining available coverage. We received payments of $2.2 million from an insurer in the GST Coverage Block in the first quarter of 2022.

The insurance available to cover current and future asbestos claims is from comprehensive general liability and excess liability policies that cover EnPro Holdings and certain of its other subsidiaries in addition to GST for periods prior to 1985 and therefore could be subject to potential competing claims of other covered subsidiaries and their assignees.

Basis of Presentation

Basis of Presentation

The accompanying interim consolidated financial statements are unaudited, and certain related information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted in accordance with Rule 10-01 of Regulation S-X. They were prepared following the same policies and procedures used in the preparation of our annual financial statements and reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of results for the periods presented. The Consolidated Balance Sheet as of December 31, 2021 was derived from the audited financial statements included in our annual report on Form 10-K for the year ended December 31, 2021. The results of operations for the interim periods are not necessarily indicative of the results for the fiscal year. These consolidated financial statements should be read in conjunction with our annual consolidated financial statements for the year ended December 31, 2021 included within our annual report on Form 10-K.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amount of assets and liabilities and the disclosures regarding contingent assets and liabilities at period end and the reported amounts of revenue and expenses during the reporting period.

All intercompany accounts and transactions between our consolidated operations have been eliminated.
