2023 Annual Report to Shareholders

2023 HIGHLIGHTS

Through a number of strategic moves in 
recent years, we have successfully increased 
our profitability while optimizing the balance 
between our two complementary segments. 
We continue to leverage our strong balance 
sheet to invest in organic growth opportunities 
and pursue select strategic acquisitions.

Record profitability in the Sealing Technologies 
segment helped offset a slowdown in the 
Advanced Surface Technologies (AST) 
segment, largely caused by weakness in the 
global semiconductor industry. Throughout 
the year, we achieved solid profitability, 
despite top-line headwinds in AST.

In December 2023, we announced the 
acquisition of Advanced Micro Instruments, 
Inc. (AMI) for $210 million, broadening our 
capabilities in compositional analysis in 
the Sealing Technologies segment. This 
acquisition, which we completed in January 
2024, advances the segment’s strategy to 
build upon its portfolio of businesses that 
offer leading-edge applications to safeguard 
critical environments. 

This and every year, our enduring values of 
Safety, Excellence & Respect continue to be 
cultural cornerstones for our colleagues, 
encouraging them to practice physical and 
psychological safety, open and creative 
communication and applied engineering 
and technology excellence as they continue 
delivering differentiated value to our customers.

We foster an inclusive environment where all 
employees can flourish in our culture where 
human development is viewed as being 
equally important to, and intertwined with, 
excellent financial results. 

Enpro advanced its excellent safety record 
in 2023 with significant improvements in key 
safety metrics company wide. Safety is our 
first core value, and we strive to create a 
productive and injury-free workplace for our 
colleagues.

We continue to advance a number of 
sustainability initiatives consistent with our 
core values. In 2023, we achieved our goal of 
reducing greenhouse gas (GHG) emissions 
by 3% per million dollars of revenue and are 
aiming to reduce emissions by another 3% 
in 2024. 

In December 2023, we completed our 
corporate name change to Enpro Inc. in 
recognition of our forward strategy and 
successful portfolio transformation. Our 
remarkable evolution has been made 
possible because of the incredible work of 
the Enpro team to advance our key strategic 
priorities and deliver for our customers. 

Fellow Shareholders

In 2023, Enpro Inc. executed 
well, showcasing the resilience 
of our business model and the 
robustness of our balanced 
portfolio. We delivered record 
profitability in our Sealing 
Technologies segment that 
partially offset the slowdown 
in our Advanced Surface 
Technologies segment related 
to demand headwinds in the 
global semiconductor market. 

Eric A. Vaillancourt
President and Chief Executive Officer

We continue to reinforce our foundation for sustained value creation by enhancing our 
differentiated offerings as we focus on markets with projected above-average growth and 
superior profitability, such as semiconductor, sustainable power generation, pharmaceutical 
and photonics.

This year, we strategically invested in Enpro’s long-term growth. Our businesses offer critical 
products and solutions that safeguard critical environments, offer technological competitive 
advantages, and possess high barriers to entry, with stringent customer qualifications and 
high switching costs. In addition to investing in organic growth opportunities across the 
company throughout the year, we broadened our portfolio with the acquisition of Advanced 
Micro Instruments, Inc. (AMI). AMI is an industry leader in innovative analyzers and sensing 
technologies that enable process efficiency, enhance safety and facilitate the clean energy 
transition. The acquisition expands the core enabling capabilities of our Sealing Technologies 
portfolio into compositional analysis, allowing us to better support customers operating in 
critical industries such as midstream natural gas, biogas, industrial processing, cryogenics,

food processing, laboratory, wastewater and aerospace markets. Our strategy to expand our 
offerings of highly engineered products and technologies that safeguard critical environments 
in key secular growth markets remains unchanged. 

Our board of directors provides strategy and executive succession oversight. Our independent 
board of directors represents a diverse set of backgrounds, skills and experiences across 
manufacturing, risk management, innovation, and product development and marketing to 
effectively oversee our growth strategy. Following the addition of two new independent 
directors in the last two years, we remain focused on ongoing board refreshment to ensure that 
we have the right combination of skills and fresh insights. As part of our effective executive 
leadership succession planning, we appointed Joe Bruderek to the Chief Financial Officer 
role, succeeding Milt Childress, effective April 1, 2024. We look forward to benefitting from 
Joe’s record of driving profitability through financial discipline and to Joe leading impactful 
strategic initiatives in the coming year and beyond. 

We are committed to Empowering Technology with Purpose in support of our growth 
priorities and colleague development. Our sustainability priorities are closely aligned with 
our corporate strategy as we continue to lead with our core values of Safety, Excellence 
and Respect in everything we do. On Safety, we are celebrating a 59% reduction in our Total 
Recordable Incident Rate as well as a 47% reduction in Lost Time Case Rate in 2023, building 
upon our already excellent safety record. We are implementing a number of sustainability 
initiatives that will increase the efficiency of our operations. We were pleased to have 
achieved the previously announced goal of reducing greenhouse gas (GHG) emissions 
by 3% per dollar of revenue by the end of 2023. In 2024, we will work toward reducing GHG 
emissions by another 3%, while advancing other sustainability and developmental disciplines 
throughout the organization.

Enpro enters 2024 positioned well with a strong balance sheet. We continue to invest in our 
optimized portfolio of businesses with capital expenditures expected to rise toward $60 million 
this year, two-thirds of which will support growth opportunities. Our pipeline of inorganic growth 
opportunities meeting our strategic and financial objectives remains active, as we continue 
to exhibit patience and discipline in evaluating potential acquisitions. Finally, our current plan 
is to continue steady increases in our dividend over time as we pursue our balanced capital 
allocation strategy.

We have a vibrant working environment at Enpro, as we Empower Technology with Purpose. 
As we reiterate every year, we are focused on delivering outstanding financial results by 
providing products and solutions that enable the safeguarding of critical environments across 
many growing end markets by applying our differentiated technologies and engineering

to learn, challenge themselves and each other, and develop. Honoring our values of Safety, 
Excellence, and Respect, we believe diversity of people, and of thought, advance these 
priorities as we maintain our commitments to the communities we serve and contribute to 
a sustainable future. 

We are excited about our bright future as we look forward to 2024 and beyond. I would 
like to thank our talented team members across Enpro for executing on our strategic 
priorities, delivering for our customers and propelling forward our leading-edge 
capabilities and differentiated way of working, and all of our stakeholders for their 
support as we drive forward our enduring, value-creating strategy.

Sincerely,

Eric A. Vaillancourt

PART I

ITEM 1.

BUSINESS

As used in this report, the terms “we,” “us,” “our,” “Enpro” and “Company” mean Enpro Inc. and its subsidiaries (unless 
the context indicates another meaning). The term “common stock” means the common stock of Enpro Inc., par value $0.01 per 
share. 

Background

We were incorporated under the laws of the State of North Carolina on January 11, 2002, as a wholly owned subsidiary 

of Goodrich Corporation (“Goodrich”). The incorporation was in anticipation of Goodrich’s announced spin-off of its 
Engineered Industrial Products segment by a distribution of the Company's common stock to existing Goodrich shareholders. 
The distribution took place on May 31, 2002.

Today, we are a leading-edge industrial technology company focused on critical applications across a diverse group of 

growing end markets such as semiconductor, photonics, industrial process, aerospace, food, biopharmaceuticals and life 
sciences. Enpro is a leader in applied engineering and designs, develops, manufactures, and markets proprietary, value-added 
products and solutions that contribute key functionality or safeguard a variety of critical environments. Over the past several 
years, we have executed several strategic initiatives to create a portfolio of businesses that offers proprietary, industrial 
technology-related products and solutions with high barriers to entry, compelling margins, strong cash flow, and perpetual 
recurring/aftermarket revenue in markets with favorable secular tailwinds. These initiatives, described in “Acquisitions” and 
“Dispositions” below, have increased our ability to provide solutions to the semiconductor, life sciences, and other technology 
industries. As of December 31, 2023, our continuing operations had 13 primary manufacturing and service facilities 
(approximately 50,000 square feet or larger) located in 6 countries, including the United States.

industry. NxEdge engineers, manufactures and services leading-edge systems and components critical in the production of  
semiconductors, offers technically-advanced coatings and surface treatments along with refurbishment services and spare parts. 
NxEdge is included as part of our Advanced Surface Technologies segment. We paid $853.9 million, net of cash acquired, for 
the business.

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

Alluxa works in collaboration with customers across major end markets to provide customized, complex precision coating 

solutions through its specialized technology platform and proprietary processes. Alluxa has long-standing customer 
relationships across its diversified customer base, serving customers across the Americas, Europe, and Asia. Founded in 2007, 
Alluxa has two locations in California and is headquartered in Santa Rosa, California.

In connection with the completion of the transaction, we entered into a limited liability operating agreement with respect 
to the Alluxa Acquisition Subsidiary in connection with the rollover transaction, with three equity owners of Alluxa, who were 
also executives of Alluxa, receiving approximately 7% of the equity interests of the Alluxa Acquisition Subsidiary in return for 
their contribution of the rollover shares of Alluxa. In the first quarter of 2024, we acquired all of these equity interests and 
became the sole owner of Alluxa. 

In September 2019, Lunar Investment LLC ("Lunar"), a subsidiary of Enpro, acquired all of the equity securities of 
LeanTeq Co, LTD. and its affiliate LeanTeq LLC (collectively referred to as "LeanTeq"). As part of the transaction, two of the 
equity owners of LeanTeq, who were executives of the acquired entity (the "LeanTeq Executives"), acquired approximately a 
10% ownership share of Lunar in the form of rollover equity. Founded in 2011 and headquartered in Taoyuan City, Taiwan, 
LeanTeq has two locations in Taiwan and one in the United States (Silicon Valley). LeanTeq primarily provides refurbishment 
solutions for critical components and assemblies used in state-of-the-art semiconductor manufacturing equipment. This 
equipment is used to produce technologically advanced microchips for smartphones, autonomous vehicles, high-speed wireless 
connectivity, artificial intelligence, and other leading-edge applications. LeanTeq partners closely with original equipment 
manufacturers throughout the development and production lifecycle to achieve Process of Record qualifications, enabling long-
term, recurring aftermarket revenue. Aftermarket refurbishment solutions have historically represented approximately 65% of 
LeanTeq's total sales. LeanTeq’s suite of solutions includes cleaning, coating, analytical testing, inspection and verification, kit 
assembly, failure analysis, and other value-added solutions. LeanTeq is included as part of our Advanced Surface Technologies 
segment. During the fourth quarter of 2022, Enpro acquired all of the equity interests of Lunar owned by the LeanTeq 
Executives and became the sole owner of LeanTeq.

Dispositions

During the third quarter of 2022, we entered into an agreement to sell our GGB business and announced our intention to 
sell Garlock Pipeline Technologies, Inc. ("GPT"), which was sold in January 2023.  These businesses, along with Compressor 
Products International ("CPI"), which was divested on December 21, 2021, comprised our entire Engineered Materials segment 
("Engineered Materials"). As a result of classifying the GGB and GPT businesses as held for sale in the third quarter of 2022, 
we determined Engineered Materials to be a discontinued operation. Unless otherwise indicated, amounts provided in Part I 
pertain to continuing operations only (see Note 20 to our Consolidated Financial Statements in this Form 10-K for information 
on discontinued operations and the related disposition of those operations).

On January 30, 2023 we completed the sale of GPT. In 2023, we received $28.9 million, net of transaction fees and cash 

sold, resulting in a pretax gain of $14.6 million recognized in the first quarter of 2023.

2

The sale of GGB closed on November 4, 2022 to The Timken Company. We received $298.2 million, net of transaction 
fees and cash sold, including $3.1 million of payments made in Q1 of 2023. We recorded a pre-tax gain of  $189.1 million as 
part of our discontinued operations in the fourth quarter of 2022.

The sale of  GGB included a subsidiary of our Sealing Technologies segment which is not part of the discontinued 
operations described above. The results of operations of this subsidiary are included in continuing operations for all periods 
being reported. As a result of this sale, we recorded a $0.4 million loss in the fourth quarter of 2022 in other expense in our 
consolidated statement of operations.

On October 12, 2021, we entered into an Equity and Asset Purchase Agreement (the “Purchase Agreement”) providing for 

the sale of specified equity interests and assets of our CPI business, which had been included in our Engineered Materials 
segment. The sale closed on December 21, 2021 and we recorded a pretax gain of $117.6 million in the fourth quarter of 2021 
as a result of this transaction.   

On September 2, 2021, we sold certain assets and liabilities of our polymer components business unit, which was 
principally located in Houston, Texas and had been included in our Sealing Technologies segment. As a result of the sale, we 
recorded a pre-tax gain of $19.5 million in other income (expense) on our Consolidated Statements of Operations. 

Operations

We manage our business as two segments: a Sealing Technologies segment and an Advanced Surface Technologies 
segment. Our reportable segments are managed separately based on differences in their respective products and solutions, and 
end-customers. For financial information with respect to our business segments, see Item 7, “Management’s Discussion and 
Analysis of Financial Condition and Results of Operations – Results of Operations,” and Note 18 to our Consolidated Financial 
Statements. Item 7 contains information about sales and profits for each segment, and Note 19 contains information about each

measurement and sensing applications; sanitary gaskets; hoses and fittings for hygienic process industries; fluid transfer 
products for the pharmaceutical and biopharmaceutical industries; and commercial vehicle solutions used in wheel-end and 
suspension components that customers rely upon to ensure safety on our roadways. 

3

           
 
 
 
 
 
 
 
 
These products are used in a variety of markets, including chemical and petrochemical processing, nuclear energy, 

hydrogen, natural gas, food and biopharmaceutical processing, primary metal manufacturing, mining, water and waste 
treatment, commercial vehicle, aerospace, medical, filtration and semiconductor fabrication.  In all these industries, the 
performance and durability of our proprietary products and solutions are vital for the safety and environmental protection of our 
customers’ processes.  Many of our products and solutions are used in highly demanding applications, often in incredibly harsh 
environments; for example, where extreme temperatures, extreme pressures, corrosive environments, strict tolerances, or worn 
equipment create challenges for product performance.  

Sealing Technologies offers customers widely recognized applied engineering, innovation, process know-how and 

enduring reliability, driving a lasting aftermarket for many of our products and solutions.  Aftermarket or recurring revenue 
approximates two-thirds of our Sealing Technologies segment’s total revenue.   

Garlock consists of two companies: Garlock Sealing Technologies (GST) and Garlock Hygienic Technologies (GHT).  

GST engineers, designs, manufactures and markets metallic, non-metallic and composite material gaskets; dynamic seals; 

compression packing; hydraulic components; expansion joints; and wall penetration products.

Gasket products are used for sealing flange joints in a number of applications including in chemical, petrochemical and 

pulp and paper processing facilities where high pressures, high temperatures and corrosive chemicals create the need for 
specialized and highly engineered sealing products.  Our products are also used in sanitary markets, such as food and beverage 
and pharmaceuticals, where product integrity and safety are extremely important. We sell these gasket products under a number 
of brand names, including:  Garlock®, Gylon®, Blue-Gard®, ONE-UP®, Bio-Pro®, Tuf-Steel®, Detectomer®, and LINK-
SEAL®. These products have a long-standing reputation for performance and reliability within the industries we serve. 

Dynamic elastomeric seals are used in rotating applications to contain the lubricants that protect bearings from excessive 

friction and heat generation.  Because these sealing products are utilized in dynamic applications, they are subject to wear.  
Durability, performance, and reliability are, therefore, critical requirements of our customers.  These rotary seals are used for 
many markets, including for demanding applications in the steel, machine building, and mining and pulp and paper processing 
industries, under the well-known brand names Klozure® and PS Seal.

Compression packing is used to provide sealing in pressurized, static and dynamic applications such as pumps and valves.  

Major markets for compression packing products are the pulp and paper, mining, petrochemical and hydrocarbon processing 
industries. Branded products for these markets include 9000 EVSP®, Quickset®, and Graph-lock®.

GHT, includes Rubber Fab and The Aseptic Group, which together, design, manufacture and sell fluid process solutions, 

including: single-use hygienic seals, tubing, components and assemblies, primary for food and pharma markets.

Technetics designs, manufactures and sells high performance metal seals, mechanical seals, and elastomeric seals.  These 
products are used in extreme applications for a variety of industries, including semiconductor, aerospace (including commercial 
space), power generation, oil and gas, life sciences and other markets.  Technetics’ brands include HELICOFLEX®, 
TEXEAL®, FELTMETAL™, CEFILAC GPA®, Qualiseal®, CEFIL’AIR®, and ORIGRAF®.

Technetics Semi, LeanTeq, and Alluxa.  Our AST segment applies proprietary technologies, processes, and capabilities to 
deliver a highly differentiated suite of products and solutions for challenging applications in high-growth markets.  The 
segment’s products and solutions are used in demanding environments requiring performance, precision and repeatability, with 
a low tolerance for failure.  AST’s products and solutions include:  (i) cleaning, coating, testing, refurbishment and verification 
for critical components and assemblies used in state-of-the-art advanced node semiconductor manufacturing equipment, (ii)  
designing, manufacturing and selling specialized optical filters and proprietary thin-film coatings for the most challenging 
applications in the industrial technology, life sciences, and semiconductor markets, (iii) engineering and manufacturing 
complex front-end wafer processing sub-systems and new and refurbished electrostatic chuck pedestals for the semiconductor 
equipment industry, and (iv) engineering and manufacturing edge-welded metal bellows for the semiconductor equipment 
industry and critical applications in the space, aerospace and defense markets.  In many instances, AST capabilities drive 
products and solutions that enable the maintenance of our customers’ high-value processes through an entire life cycle.

NxEdge is an advanced manufacturing, special processing (cleaning, coating, surface treatments), and refurbishment 
solutions provider. NxEdge serves customers across the semiconductor supply chain, including top-tier global integrated device 
manufacturers (“IDMs”) and original equipment manufacturers (“OEMs”).  NxEdge’s unique set of vertically integrated 
capabilities with proprietary processes has resulted in a broad range of qualifications at top customers. 

Technetics Semi engineers and manufactures 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. 
These capabilities are also leveraged for high reliability in critical applications for space, aerospace and defense markets.

state-of-the-art, advanced equipment.  Alluxa partners with customers across major end markets to provide customized, 
complex precision coating solutions through Alluxa’s specialized technology platform and proprietary processes.  

Customers. Our Advanced Surface Technologies segment sells products and solutions to OEMs, IDMs, industrial agents 

and distributors, and end users worldwide. Advanced Surface Technologies’ products and solutions are offered to global 
customers, with approximately 34% of sales delivered to customers outside the United States in 2023.  Representative 
customers include leading global manufacturers of semiconductor manufacturing equipment, such as Applied Materials and 
ASML, as well as manufacturers of equipment used in the life sciences and industrial technology industries and government 
defense contractors.  Due to consolidation in the semiconductor manufacturing equipment industry, a small number of 
companies control a significant majority of the global production of semiconductor manufacturing equipment.  As a result, the 
segment is dependent on certain key relationships with customers in that industry and the loss of one or more of those key 
customers or other adverse changes in the segment’s relationships with those customers could have a material adverse effect on 
our business, financial condition, results of operations and cash flows.

Competition. Competition in the markets we serve is based on technology differentiation, process know-how, proven 

performance and reliability, as well as price, customer service, application expertise, technical support, delivery terms, breadth 
of offerings, reputation for quality, global footprint and the availability of products and solutions. We believe that our 
significant competitive advantages include our technological knowledge, proprietary processes, manufacturing and analytical 

5

capabilities and record of performance, which enable us to satisfy the substantial upfront qualification processes required by 
many of our customers.  The competitive landscape in the United States for advanced manufacturing, coating and refurbishment 
for the semiconductor supply chain includes several providers other than NxEdge, with no provider having a dominant market 
position. NxEdge has a broad offering of special processes and we believe a higher level of vertical integration than most of its 
competitors.  In the semiconductor cleaning space, our competitors include a limited number of other providers of cleaning 
solutions, primarily in Taiwan, Japan, South Korea and the United States, with no provider having a dominant global market 
position. The optical coatings market is highly fragmented, with numerous small competitors to Alluxa.  Competitors of 
Technetics Semi include Mirapro, FMI/NGK, KSM and Senior Flexonics.

Raw Materials and Components. Our Advanced Surface Technologies segment uses ultra-high purity chemicals, 

fluoropolymers, elastomeric compounds, technical ceramics, rare earth materials, specialty substrates, common and exotic 
metals. We believe that these raw materials and components are generally available from various suppliers, with occasional, 
isolated and short-term constraints.

Research and Development 

Our research and development efforts strengthen our product portfolios in our more traditional markets while 

simultaneously creating distinctive and breakthrough products and solutions across the company. We utilize a process to move 
innovations from concept to commercialization, and to identify, analyze, develop and implement new product concepts and 
opportunities to expand market adjacencies with differentiated and compelling products that solve critical problems for our 
customers.

We employ scientists, engineers and technicians throughout the organization to develop, design and test new and 

improved products and solutions. We work closely with our customers to identify issues and solve technical problems for 
critical applications. The majority of our research and development spending typically is directed toward the development of 
new solutions for the most demanding environments, the development of technology to support the production, cleaning and 
refurbishment of critical semiconductor manufacturing equipment components, and advancing our technological and process 
know-how to develop opportunities in new and/or adjacent niche markets that will continue to differentiate the company. 

Backlog

At December 31, 2023, we had a backlog of orders valued at $225.4 million, of which  $110.4 million related to Sealing 

Technologies and $115.0 million related to Advanced Surface Technologies compared with $310.7 million at December 31, 
2022, of which $123.9 million related to Sealing Technologies and $186.8 million related to Advanced Surface Technologies. 
Approximately 5% of the December 31, 2023 backlog is expected to be filled beyond 2024.  Backlog represents orders on hand 
that we believe to be firm. However, there is no certainty the backlog orders will result in actual sales at the times or in the 
amounts ordered. 

Quality Assurance

We believe the quality of our products and solutions is among the most important factors in developing and maintaining 
strong, long-term relationships with our customers. In order to meet the exacting requirements of our customers, we maintain 
stringent standards of quality control. We routinely employ in-process inspection by using testing equipment as a process aid 
during all stages of development, design and production to ensure product quality and reliability. These include state-of-the-art 
CAD/CAM equipment, statistical process control systems, laser tracking devices, failure mode and effect analysis, and 
coordinate measuring machines. We are able to extract numerical quality control data as a statistical measurement of the quality 
of the parts being manufactured from our Computer Numerical Control ("CNC") machinery. In addition, we perform quality 
control tests on parts that we outsource. As a result of our practices, we are able to significantly improve the quality of the 
services we provide and the parts we manufacture, avoid and reduce defects, and improve efficiency and reliability.

As of December 31, 2023, 31 of our manufacturing and service facilities were ISO 9000 certified. Three of our facilities 

are ISO 14001 certified. 

Patents, Trademarks and Other Intellectual Property

We maintain a number of patents and trademarks issued by the U.S. and other countries relating to the name and design 

of our products and have granted licenses to some of these patents and trademarks. We routinely evaluate the need to protect 
new and existing products through the patent and trademark systems in the U.S. and other countries. We also have unpatented 
proprietary information, consisting of engineering, design, and process know-how, along with trade secrets relating to the 
design, manufacture and operation of our products and their use, and to certain services we perform. Except for proprietary 
formulations and know-how in our Advanced Surface Technologies segment, we do not consider our business as a whole to be 

6

materially dependent on any particular patent, patent right, trademark, trade secret or license granted or group of related patents, 
patent rights, trademarks, trade secrets or licenses granted.

In general, we are the owner of the rights to the products that we manufacture and sell. However, we also license certain 

intellectual property from various entities. These licenses are subject to renewal and it is possible we may not successfully 
renegotiate these licenses or they could be terminated in the event of a material breach. If this were to occur, our business, 
financial condition, results of operations and cash flows could be adversely affected.

Human Capital

As of December 31, 2023, we had approximately 3,500 employees, of which approximately 66% are in North America, 

12% in Europe, and 22% in Asia Pacific.  

We strive to create an environment where all colleagues can flourish and develop, and view human development as a 

basic right, and a core foundation to achieving excellence. Enpro is a dual-bottom line company - with the development of our 
colleagues and their excellence inextricably linked to a productive environment that drives strong financial performance. Safety, 
excellence, and respect are our enduring core values and are the standard by which we measure all our actions, including how 
we treat our colleagues, physically and psychologically.  

In 2023, we introduced a new performance management and development process, placing emphasis on both manager 

engagement and employee ownership. We regularly conduct employee engagement and satisfaction surveys, including one 
completed in early 2023. Results from these surveys and engagement activities help senior management drive advances in our 
workplace and culture as we continuously focus on ways to improve our way of working.  

Focus on Safety and Wellbeing of our Employees. Our core value of safety includes physical safety on our factory floors 

and the wellness and psychological safety of colleagues. We have worked for many years to develop a world-class safety 
program and culture, where the intention is that each colleague goes home each day as healthy as they arrived. Our commitment 
to safety has resulted in our being the only public company to have been recognized on three separate occasions by EHS Today 
as “America’s Safest Company.”   Each year, we enhance our safety culture and safety programs. In 2023, we strengthened our 
safety onboarding programs so that our newest colleagues can thoroughly understand our safety culture and expectations, which 
are often much different from their prior places of employment. In 2024, we are working towards alignment with ISO 45001 at 
our major manufacturing locations. This alignment will drive our continual improvement efforts within safety. 

Competitive Pay, Benefits and Equity:  We provide comprehensive compensation and benefits programs that are 
designed to attract and retain colleagues – our most valuable resource. Our compensation programs include a focus on building 
long-term value and alignment with our stakeholders, including a sizable portion of compensation at appropriate levels 
designed to foster a culture of ownership and alignment with our shareholders. We have improved our benefit programs each 
year to meet the changing needs of our employees and their families. In the United States, this includes a company-wide 
minimum wage of $15 per hour, a 401k plan with an above-market company match, an award-winning health and wellbeing 
program, flexible vacation, and time off policies, enhanced employee assistance programs, paid family leave, and 
comprehensive healthcare benefits, as well as company-paid long-term disability, critical illness, and accident coverage.  

We continue to focus on the mental wellbeing of our colleagues through company-wide resource groups that focus on 

mental health and inclusion, as well as through our employee assistance programs.   

Focus on Diversity and Respect.   A diverse workforce and a commitment to diverse, innovative thinking are critical to 
our long-term growth and success. We continue to utilize inclusive practices within our talent acquisition practices, including 
diverse candidate slates and diverse interview panels. We have implemented tools and structures to reduce bias during the 
interview and selection process, including unconscious bias training. We provided Diversity Without Division training to our 
first line supervisors. Our gender and ethnic/racial diversity including senior management and through two levels down is 47% 
diverse, a testament to our focus on creating a diverse and inclusive environment, and one with opportunity for growth and 
development.  

The positive impact of our care, compassion, and flexible programs is demonstrated by our employee retention rates. In a 

market with volatile turnover, our aggregate retention rates are at or above market level, in part due to our culture and due to 
our progressive approach to employee development and focus on employee well-being.  

Focus on the Communities and our New Employee Assistance Fund. In 2020, we launched the Enpro Foundation to 
support charitable organizations in the communities where our colleagues live and work. Enpro has contributed $1.75 million to 
the Enpro Foundation since its formation in 2020 and our Foundation has made $690,000 in donations, with a special focus on 
charitable organizations nominated by our colleagues. Through our Foundation, we have created and funded an employee 

7

assistance fund, administered by a third-party that specializes in this type of fund, where we can confidentially assist employees 
that are facing difficult challenges, including family sickness or impact from natural disasters or other tragedies, in a way that is 
objective and respectful.

ITEM 1A.

RISK FACTORS

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

Risks Related to Our Business

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

The markets in which we sell our products and solutions, particularly wafer fab equipment for semiconductor 

manufacturing, chemical companies, petroleum refineries, heavy-duty trucking, and capital equipment are, to varying degrees, 
cyclical and have historically experienced periodic downturns. Prior downturns have been characterized by diminished product 
demand, excess manufacturing capacity and subsequent erosion of average selling prices in these markets resulting in negative 
effects on our net sales and results of operations. The wafer fab equipment for semiconductor manufacturing market, has 
historically been characterized by rapid changes in demand due to changes in electronics demand, economic conditions (both 
general and in the semiconductor and electronics industries), industry supply and demand, prices for semiconductors, and the 
ability of fabricators to manufacture increasingly complex and costly semiconductor devices. A prolonged and severe 
downward cycle in our markets, particularly in our semiconductor markets, could have a material adverse effect on our 
business, financial condition, results of operations and cash flows.

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

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

The reliance of our Advanced Surface Technologies segment on a small number of significant customers may adversely 
affect our financial results

A majority of the revenues of our Advanced Surface Technologies segment are derived from manufacturing, cleaning, 

coating and refurbishing components used in advanced node semiconductor manufacturing equipment. Due to consolidation in 
the semiconductor manufacturing equipment industry, a small number of companies control a significant majority of the global 
production of semiconductor manufacturing equipment. As a result, the segment is dependent on certain key relationships with 
customers in that industry, including a customer that accounted for approximately 26% of our 2023 consolidated net sales, and 
the loss of the segment’s relationship with that customer or other key customers or other adverse changes in the segment’s 
relationships with those customers could have a material adverse effect on our business, financial condition, results of 
operations and cash flows. Consolidation among our customers, or a decision by any one or more of our customers to no longer 
outsource the type of solutions provided by our Advanced Surface Technologies segment, may further concentrate our business 

8

in a limited number of customers and expose us to increased risks relating to dependence on an even smaller number of 
customers. 

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

The marketing success of many of our businesses in the U.S. and abroad depends largely upon our independent agents’ 

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

Increased costs for raw materials, the termination of existing supply arrangements or other disruptions of our supply chain 
has had, and could continue in the future to have, a material adverse effect on our business.

We have seen organic changes related to price increases of raw materials over the past several years. The prices of some 

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

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

We believe that proprietary products, processes, and technology are important to our success. If we are unable to 

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

Our competitors may capture market share from us by selling products that claim to mirror the capabilities of our 

products or technology. Without sufficient protection nationally and internationally for our intellectual property, our 
competitiveness worldwide could be impaired, which would negatively impact our growth and future revenue. As a result, we 
may be required to spend significant resources to monitor and enforce our intellectual property rights.

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

In general, we are the owner of the rights to the products and services that we manufacture and provide. However, we 

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

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

Our products and solutions are often used in critical applications in demanding environments, including in the nuclear, oil 

and gas, automotive, aerospace and pharmaceutical industries. Accordingly, product and service failures can have significant 
consequences and could result in significant product liability, warranty and other claims against us, regardless of whether our 
products and services caused the incident that is the subject of the claim, and we may have obligations to participate in the 
recall of products in which our products are components, if any of the components or services we supply prove to be defective. 

9

We endeavor to identify and obtain in established markets insurance agreements to cover certain significant risks and liabilities, 
though insurance against some of the risks inherent in our operations (such as insurance covering down-stream customer 
product recalls) is either unavailable or available only at rates or on terms that we consider excessive. Depending on 
competitive conditions and other factors, we endeavor to obtain contractual protection against uninsured risks from our 
customers, including limitations on liability and indemnification. In some cases, we are unable to obtain such contractual 
protections, and when we do, such contractual protection may not be as broad as we desire, may not be supported by adequate 
insurance maintained by the customer, or may not be fully enforceable in the jurisdictions in which our customers are located. 
Such insurance or contractual protection may not be sufficient or effective under all circumstances or against all hazards to 
which we may be subject. A successful claim or product recall for which we are not insured or for which we are underinsured 
could have a material adverse effect on us. Additionally, disputes with insurance carriers over coverage may affect the timing of 
cash flows and, if litigation with the carrier becomes necessary, an outcome unfavorable to us may have a material adverse 
effect on our results of operations.

Our business may be adversely affected by information technology disruptions.

Our business may be impacted by information technology disruptions, including information technology attacks. 

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

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

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

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

We are dependent on the continued services of our leadership team. The loss of these personnel without adequate 

replacement could have a material adverse effect on our operations. Additionally, we need qualified managers and skilled 
employees with technical and industry experience in many locations in order to operate our business successfully. From time to 
time, there may be a shortage of skilled labor, which may make it more difficult and expensive for us to attract and retain 
qualified employees. If we were unable to attract and retain sufficient numbers of qualified individuals or our costs to do so 
were to increase significantly, our operations and results of operations could be materially adversely affected.

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

Our business with government agencies, including sales to prime contractors that supply these agencies, is subject to 

government contracting risks. U.S. government contracts are subject to termination by the government, either for the 
convenience of the government or for default as a result of our failure to perform under the applicable contract. In addition, if 
we or one of our divisions were charged with wrongdoing with respect to a U.S. government contract, the U.S. government 
could suspend us from bidding on or receiving awards of new government contracts pending the completion of legal 
proceedings, and if we are  found liable, we could subject us to fines, penalties, repayments and treble and other damages, and/
or debarment from bidding on or receiving new awards of U.S. government contracts. 

10

Climate change and legal or regulatory responses thereto may have an adverse impact on our business and results of 
operations.

There is growing concern that a gradual increase in global average temperatures as a result of increased concentration of 

carbon dioxide and other greenhouse gases in the atmosphere will cause significant changes in weather patterns around the 
globe and an increase in the frequency and severity of natural disasters. Many of our manufacturing facilities use significant 
amounts of electricity generated by burning fossil fuels, which releases carbon dioxide. Such climate change may impair our 
production capabilities, disrupt our supply chain or impact demand for our products. Growing concern over climate change also 
may result in additional legal or regulatory requirements designed to reduce or mitigate the effects of carbon dioxide and other 
greenhouse gas emissions on the environment. Increased energy or compliance costs and expenses as a result of increased legal 
or regulatory requirements may cause disruptions in, or an increase in the costs associated with, the manufacturing and 
distribution of our products. The impacts of climate change and legal or regulatory initiatives to address climate change could 
have a long-term adverse impact on our business and results of operations. If we fail to achieve or improperly report on our 
progress toward achieving our goals and commitments to reduce our carbon footprint or in environmental and sustainability 
programs and initiatives, the results could have an adverse impact on our business, financial position, results of operations or 
cash flows.

Evolving regulatory restrictions on per- and polyfluoroalkyl substances (PFAS) may restrict the manufacture or use of 
fluoropolymers, including PTFE, which are currently included as critical components in certain of our products.

In February 2023, the European Chemical Agency (ECHA) proposed several options for restricting the manufacture, 

import and use of PFAS in the EU under the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) 
regulations, potentially including PTFE and/or the fluorosurfactants that our suppliers use to manufacture PTFE. ECHA is in 
the process of evaluating these proposed options and preparing opinions on the socio-economic, environmental and health 
impacts of the proposal for consideration by the European Commission. PTFE resins are currently a critical raw material in the 
manufacture of certain of our products, and are included as components of several of our final products. If the manufacture or 
use of PTFE resins were restricted by this or other emerging regulations in the coming years, or if a substantial number of our 
suppliers discontinued production of PTFE resins due to regulatory pressures, and if we were unable to develop products using 
substitute materials that provide the same reliability and performance as our current products, our results of operations could be 
adversely affected.

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

Our business may be negatively impacted by numerous other risks. For example, medical and other healthcare costs may 

continue to grow faster than general inflation or employees may receive more or higher cost services in future periods. 
Initiatives to address these costs, such as consumer driven health plan packages, may not successfully reduce these expenses to 
the extent expected or required. Failure to offer competitive employee benefits may result in our inability to recruit or maintain 
key employees. Other risks to our business include potential changes in environmental rules or regulations, which could 
negatively impact our manufacturing processes, or changes to the magnitude of costs at existing environmental sites. Use of 
certain chemicals and other substances could become restricted or such changes may otherwise require us to incur additional 
costs which could reduce our profitability and impair our ability to offer competitively priced products. Additional risks to our 
business include global or local events which could significantly disrupt our operations. Certain of our facilities are located in 
areas at risk for hurricanes, earthquakes, wildfires and/or flooding. Such natural disasters, as well as terrorist attacks, political 
insurgencies, pandemics and electrical grid disruptions and outages are some of the unforeseen risks that could negatively affect 
our business, financial condition, results of operations and cash flows.

Risks Related to Our Acquisition Activities

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

We expect to continue to make acquisitions in the future. Acquisitions involve numerous inherent challenges, such as 

properly evaluating acquisition opportunities, properly evaluating risks and other diligence matters, ensuring adequate capital 
availability and balancing other resource constraints. There are risks and uncertainties related to acquisitions, including: 
difficulties integrating acquired technology, operations, personnel and financial and other systems; unrealized sales expectations 
from the acquired business; unrealized synergies and cost savings; unknown or underestimated liabilities; diversion of 
management attention from running our existing businesses; and potential loss of key management, employees or customers of 
the acquired business. In addition, internal controls over financial reporting of acquired companies may not be up to required 
U.S. public company standards. Our integration activities may place substantial demands on our management, operational 

11

resources and financial and internal control systems. Customer dissatisfaction or performance problems with an acquired 
business, technology, service or product could also have a material adverse effect on our reputation and business.

Risks Related to Our Prior Ownership of Disposed Businesses

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

We have contingent liabilities related to discontinued operations and previously owned businesses of our predecessors, 

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

Claims could arise relating to products, facilities, employees or former employees, or other matters related to our 
discontinued operations. Some of these claims could seek substantial monetary payments. For example, Enpro has entered into 
an Administrative Settlement Agreement and Order on Consent for Interim Removal Action with the Environmental Protection 
Agency for the assessment and potential remediation of eight surface uranium mines in Arizona on the basis that our EnPro 
Holdings subsidiary, through which we hold most of our operating subsidiaries, was a potentially responsible party under 
federal environmental laws as the successor to a former operator in the 1950s of those mines. Further, we could potentially be 
liable with respect to firearms manufactured prior to March 1990 by Colt Firearms, a former operation of a corporate 
predecessor of EnPro Holdings, and electrical transformers manufactured prior to May 1994 by Central Moloney, another 
former operation of that corporate predecessor.

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

Risks Related to Our International Operations

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

Because we sell our products and provide services in a number of foreign countries, we are subject to risks associated 
with doing business internationally. In 2023, we derived approximately 40% of our net sales from sales of our products and 
solutions outside of the U.S. Outside the U.S., we operate 6 primary manufacturing and service facilities (approximately 50,000 
square feet or larger) located in 5 countries. Our sales and operating activities outside of the U.S. are, and will continue to be, 
subject to a number of risks, including:

•

•

•

•

•

•

•

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

adverse changes in foreign tax, legal and regulatory requirements;

political and economic instability, including any conflict or threat of conflict that may affect Taiwan;

difficulty in protecting intellectual property;

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

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

differing labor regulations; and

12

•

acts of hostility, terror or war.

Any of these factors, individually or together, could have a material adverse effect on our business, financial condition, 

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

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

We intend to continue to pursue international growth opportunities, which could increase our exposure to risks associated 
with international sales and operations. As we expand our international operations, we may also encounter new risks that could 
adversely affect our revenues and profitability. For example, as we focus on building our international sales and distribution 
networks in new geographic regions, we must continue to develop relationships with reputable and qualified local agents, 
distributors and trading companies. If we are not successful in developing these relationships, we may not be able to increase 
sales in these regions.

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

cash flows.

Risks Related to Our Capital Structure

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

The agreement governing our senior secured revolving credit facility and the indenture governing our senior notes impose 

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

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

Upon a change of control, as defined under the indenture governing our senior notes and includes events that may be 

beyond our control, the holders of our senior notes have the right to require us to offer to purchase all of our senior notes then 
outstanding at a price equal to 101% of their principal amount plus accrued and unpaid interest.  In order to obtain sufficient 
funds to pay the purchase price of the outstanding notes, we expect that we would have to refinance our senior notes.  We 
cannot assure you that we would be able to refinance our senior notes on reasonable terms, if at all.  Our failure to offer to 

13

purchase all outstanding notes or to purchase all validly tendered notes would be an event of default under the indenture 
governing our senior notes. Such an event of default may cause the acceleration of our other debt.

We may incur increased interest expense as a result of our variable rate debt.

Borrowings under our revolving credit facility and our term loan facilities incur interest which is variable based on 
fluctuations in the referenced Secured Overnight Financing Rate ("SOFR"). Increases in the referenced SOFR will increase the 
Company's borrowing costs and negatively impact financial results and cash flows.

Risks Related to Ownership of Our Common Stock

The market price of our common stock may be volatile.

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

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

Our revenue and operating results may vary significantly from quarter to quarter. A high proportion of our costs are fixed, 

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

•

•

•

•

•

•

•

•

•

•

•

•

demand for our products and services;

the timing and execution of customer contracts;

the timing of sales of our products and services;

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

increases in costs due to equipment or labor issues;

changes in foreign currency exchange rates;

changes in applicable tax rates;

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

unanticipated delays or problems in introducing new products;

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

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

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

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

•

•

•

•

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

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

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

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

14

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

The anti-takeover provisions of our articles of incorporation and bylaws and provisions of North Carolina law could delay 

or prevent a change of control or may impede the ability of the holders of our common stock to change our management. In 
particular, our articles of incorporation and bylaws, among other things:

•

•

•

•

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

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

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

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

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

In the future, we may sell additional shares of our common stock to raise capital or issue shares of common stock as 

consideration in connection with an acquisition. In addition, a reasonable number of shares of our common stock are reserved 
for issuance under our equity compensation plans, including shares to be issued upon the vesting of restricted stock unit or 
performance share awards. We cannot predict the size of future issuances or the effect, if any, that they may have on the market 
price for our common stock. The issuance and sales of substantial amounts of common stock, or the perception that such 
issuances and sales may occur, could adversely affect the market price of our common stock.

ITEM 1C.

CYBERSECURITY

Risk Management Strategy

We recognize the critical importance of effectively managing cybersecurity risks to protect our businesses, intellectual 

property, employees, and customers.  We manage cybersecurity risks as part of our broader enterprise risk management 
framework, which allows us to leverage existing, robust processes for assessing the effectiveness and coverage of our controls.  

In recent years, we have invested significant time and resources to develop, implement, and maintain a robust set of 
cybersecurity measures, which all support our efforts to mitigate potential risks to the confidentiality, integrity, and availability 
of our data and critical business systems.  Since the cybersecurity risk landscape is in a constant state of change, we employ a 
continuous, multi-layered approach to assess and measure the effectiveness of our cybersecurity defenses.  Our approach 
includes using select third-party resources, including external cybersecurity consultants, auditors, and technologies, along with 
our internal staff, to benchmark, measure, and improve our cybersecurity risk management systems and processes, and ensure 
alignment with industry best practices. 

Due to the increasing risk of third and fourth-party business relationships, we implemented a Third-Party Risk 
Management (“TPRM”) Program to evaluate and monitor our network of external partners, vendors, suppliers, and service 
providers.  Capabilities of our TPRM program include continuous monitoring of third parties, secure vendor remote access, and 
security architecture to protect against cyber threats introduced through other business-to-business (“B2B”) system integrations.  

In addition to above, we have implemented and maintained the following cybersecurity measures as part of our efforts to 

assess, identify, and manage material risks from cybersecurity threats, and to protect against, detect and respond to 
cybersecurity incidents (as defined in Item 106(a) of Regulation S-K):

•

•

•

Security Operations Program - a security operations program to bolster real-time cybersecurity incident detection 
and response capabilities;

Security Control Framework - a security control framework that aligns with industry accepted best practices and 
prioritizes implementation of critical cybersecurity controls;

Incident Response Plan - a cybersecurity Incident Response Plan, designed to effectively address cybersecurity 
incidents while promoting cross-functional coordination across the organization; 

15

•

•

•

•

•

Tabletop Exercises - periodic internal and vendor-led tabletop exercises to assess the effectiveness, relevance, and 
completeness of the Incident Response Plan;

Assessments - annual cybersecurity assessments, which focus on identifying and remediating vulnerabilities that 
present the most significant organizational risks;

Training - security awareness training for all salaried personnel that highlights critical organizational risks through 
quarterly phishing simulation campaigns, “lunch and learns”, monthly communication updates, and regular 
cybersecurity learning modules; 

Insurance - cybersecurity insurance policies and periodic reviews of our policies and coverage levels; and

Monitoring Legal/Regulatory Developments – review of emerging data protection, data privacy, and other relevant 
cybersecurity laws and regulations to determine appropriate changes to cybersecurity controls and processes.

Please see Item 1A. Risk Factors in this Form 10-K for more information regarding cybersecurity-related risks that could 
materially affect our business strategy, results of operations, or financial condition, including under the heading “Our business 
may be adversely affected by information technology disruptions”.

Board and Management Oversight

Our Board of Directors has delegated to its Audit and Risk Management Committee (the “Audit Committee”), which 

consists of all of our non-management directors, the authority and responsibility to oversee our company’s compliance 
program, including our cybersecurity program. Accordingly, the Audit Committee oversees our approach to cybersecurity risk 
management and plays a critical role in the governance of our cybersecurity risk management program. 

From a management perspective, our Chief Information Security Officer (“CISO”) and Chief Information Officer 
(“CIO”) lead our cybersecurity efforts.  Our CISO has extensive experience in cybersecurity, including creating and supporting 
cybersecurity programs for larger publicly-traded companies, obtaining cybersecurity certifications, participating in relevant 
cybersecurity leadership communities, and public speaking engagements on cybersecurity topics. He leads a cross functional 
cybersecurity team, which includes members of our legal department and internal audit function.  As part of his job function, 
our CISO is charged to remain informed of the latest developments in cybersecurity, including the evolving threat landscape, as 
well as risk management improvement methods. This continual focus and understanding of the threat landscape, as well as risk 
treatment practices, is required to ensure that the CISO can effectively manage the Company’s efforts to prevent, detect, 
mitigate, and remediate cybersecurity incidents.  

Our CISO implements a program and supporting processes to proactively assess systems for vulnerabilities, while taking 

a risk-based approach to prioritize remediation steps. Should a cybersecurity incident occur, the CISO would reference an 
incident response plan and supporting playbooks to support the incident response process. We regularly test our incident 
response process by leveraging a combination of internal resources and trusted third-party consultants to test our response 
readiness and the completeness of our incident response plan, including through the use of tabletop exercises.

Our CISO and CIO regularly advise the Audit Committee on cybersecurity risks and the company’s cybersecurity 

program, including quarterly updates and comprehensive briefings to the Audit Committee at least annually. During these 
briefings, our cybersecurity leaders advise the Audit Committee regarding (i) the current threat landscape and related risks; (ii) 
the Company’s security posture and compliance efforts; and (iii) current cybersecurity strategy and recommended next steps to 
address cybersecurity threats on a risk-adjusted basis.  

Our CISO and CIO serve as members of our Compliance Committee, which is a management committee consisting of 

leaders from key functions, including legal, internal audit, finance and compliance.  The Compliance Committee receives 
regular updates from the CISO and CIO on cybersecurity risks and threats. 

The practice of our CISO and CIO is to communicate significant cybersecurity matters directly to senior management, 

including our Chief Executive Officer, Chief Financial Officer and General Counsel, which ensures that our executive 
management team remains continually informed of critical events impacting our business.  

For cybersecurity matters deemed material to the Company, senior management will communicate such matters directly 
to the Audit Committee to enable members of the Audit Committee to offer comprehensive oversight and guidance on crucial 
cybersecurity matters.

Our manufacturing capabilities are flexible and allow us to tailor the manufacturing process to increase performance and 
value for our customers and meet particular specifications. We also maintain smaller manufacturing and service facilities, sales 
offices and warehouse facilities in strategic locations in the U.S. and other countries. We believe our facilities and equipment 
are generally in good condition and are well maintained and able to continue to operate at present or higher than current levels.

LEGAL PROCEEDINGS

Descriptions of environmental and other legal matters are included in Item 7 of this annual report under the heading 
“Management’s Discussion and Analysis of Financial Condition and Results of Operations – Contingencies” and in Note 19 to 
our Consolidated Financial Statements, which descriptions are incorporated by reference herein.

In addition to the matters noted above 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.

We were not subject to any penalties associated with any failure to disclose “reportable transactions” under 

Section 6707A of the Internal Revenue Code.

In October of 2022, our board of directors authorized the expenditure program of up to $50.0 million for the repurchase
of our outstanding common shares through October 2024. We have not made any repurchases under this authorization.

In December 2023, a total of 208 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, 64 shares were valued at a price of $140.49 per share, the closing trading
price of our common stock on December 13, 2023, and 144 of these shares were valued at a price of $56.74 per share,
the closing trading price of our common stock on December 31, 2023. Accordingly, the total 208 shares were valued at a 
weighted average price of $151.74. We do not consider the transfer of shares from EnPro Holdings in this context to be 
pursuant to a publicly announced plan or program.

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 consolidated 

financial condition and operating results during the periods included in the accompanying audited Consolidated Financial 
Statements and the related notes. You should read the following discussion in conjunction with our audited Consolidated 
Financial Statements and the related notes, included elsewhere in this annual report.

Forward-Looking Statements

This report contains certain statements that are “forward-looking statements” as that term is defined under the Private 

Securities Litigation Reform Act of 1995 (the “Act”) and releases issued by the SEC. The words “may,” “hope,” “will,” 
“should,” “could,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “predict,” “potential,” “continue,” and 
other expressions which are predictions of or indicate future events and trends and which do not relate to historical matters 
identify forward-looking statements. We believe that it is important to communicate our future expectations to our 
shareholders, and we therefore make forward-looking statements in reliance upon the safe harbor provisions of the Act.

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 income from 
continuing operations attributable to Enpro Inc., adjusted diluted earnings per share attributable to Enpro Inc. continuing 
operations, 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, other than total adjusted segment 
EBITDA, to the comparable GAAP measures are included in "—Reconciliations of Non-GAAP Financial Measures to the 
Comparable GAAP Measures," while the reconciliation of total adjusted segment EBITDA is included in "—Results of 
Operations."

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

instances, AST capabilities drive products and solutions that enable the performance of our customers’ high-value processes
through an entire life cycle..

Acquisitions

On December 28, 2023, our direct, wholly owned subsidiary, EnPro Holdings, Inc. ("EnPro Holdings"), entered into an 

agreement to acquire Advanced Micro Instruments, Inc. (“AMI”), for $210 million in cash, subject to customary purchase price 
adjustments related to the final acquisition date net working capital determination. AMI is a leading provider of highly-
engineered, application-specific analyzers and sensing technologies that monitor critical parameters to maintain infrastructure 
integrity, enable process efficiency, enhance safety, and facilitate the clean energy transition. 

The acquisition closed on January 29, 2024 and thus the assets and operating results of AMI are not included in our 2023 
consolidated financial statements. (see Note 21 to our Consolidated Financial Statements in this Form 10-K for information on 
this subsequent event). AMI's financial results will be included as part of our Sealing Technologies segment beginning January 
29, 2024.

Based in Costa Mesa, California, AMI serves customers in the midstream natural gas, biogas, industrial processing, 
cryogenics, food processing, laboratory, wastewater and aerospace markets. AMI offers a portfolio of oxygen, hydrogen sulfide 
and moisture analyzers and proprietary sensing capabilities that detect contaminants in a variety of processes, including natural 
gas and biogas streams, which enable operators to avoid flaring and, thereby, reduce CO2 emissions. 

On December 17, 2021, EnPro Holdings acquired all issued and outstanding membership interests of TCFII NxEdge LLC 
(“NxEdge”). The consideration paid by EnPro Holdings was $853.9 million in cash, net of cash acquired, subject to customary 
purchase price adjustments related to the final acquisition date net working capital determination. We funded the acquisition of 
NxEdge with available cash and borrowings under our senior credit facilities. 

NxEdge is an advanced manufacturing, cleaning, coating, and refurbishment business focused on the semiconductor value 

chain, with six main facilities located in Idaho and California. Since the date of its acquisition, NxEdge has been included as 
part of the Company’s Advanced Surface Technologies segment.

23

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

Alluxa works in collaboration with customers across major end markets to provide customized, complex precision coating 

solutions through its specialized technology platform and proprietary processes. Alluxa has long-standing customer 
relationships across its diversified customer base, serving customers across the Americas, Europe, and Asia. Founded in 2007, 
Alluxa has two locations in California and is headquartered in Santa Rosa, California.

In connection with the completion of the transaction, we entered into a limited liability operating agreement with respect 
to the Alluxa Acquisition Subsidiary in connection with the rollover transaction, with three equity owners of Alluxa, who were 
also executives of Alluxa, receiving approximately 7% of the equity interests of the Alluxa Acquisition Subsidiary in return for 
their contribution of the rollover shares of Alluxa. In the first quarter of 2024, we acquired all of these equity interests in the 
Alluxa Acquisition Subsidiary for $17.9 million and became the sole owner of Alluxa. 

In September 2019, Lunar Investment LLC ("Lunar"), a subsidiary of Enpro, acquired all of the equity securities of 
LeanTeq Co, LTD. and its affiliate LeanTeq LLC (collectively referred to as "LeanTeq"). As part of the transaction, two of the 
equity owners of LeanTeq, who were executives of the acquired entity (the "LeanTeq Executives"), acquired approximately a 
10% ownership share of Lunar in the form of rollover equity. Founded in 2011 and headquartered in Taoyuan City, Taiwan, 
LeanTeq has two locations in Taiwan and one in the United States (Silicon Valley). LeanTeq primarily provides refurbishment 
solutions for critical components and assemblies used in state-of-the-art semiconductor manufacturing equipment. This 
equipment is used to produce technologically advanced microchips for smartphones, autonomous vehicles, high-speed wireless 
connectivity, artificial intelligence, and other leading-edge applications. LeanTeq partners closely with original equipment 
manufacturers throughout the development and production lifecycle to achieve Process of Record qualifications, enabling long-
term, recurring aftermarket revenue. Aftermarket refurbishment solutions have historically represented approximately 65% of 
LeanTeq's total sales. LeanTeq’s suite of solutions includes cleaning, coating, analytical testing, inspection and verification, kit 
assembly, failure analysis, and other value-added solutions. LeanTeq is included as part of our Advanced Surface Technologies 
segment. During the fourth quarter of 2022, Enpro acquired all the equity securities of Lunar owned by the LeanTeq Executives 
for an anticipated $42.8 million and became the sole owner of LeanTeq. As a result of this purchase transaction, $35.0 million 
of our Redeemable Non-Controlling Interests was reclassified as a liability. We paid $41.9 million in December 2022, which 
was the minimum purchase price for these equity securities, of which $7.8 million eliminated our outstanding deferred 
compensation liability and $34.1 million reduced the liability attributable to the redeemable non-controlling interest acquisition. 
As a result of the financial performance of LeanTeq in November 2023, we will make a final $1.1 million payment to the 
LeanTeq Executives in the first quarter of 2024. We have recorded this payment as a liability included in accrued expenses on 
our consolidated balance sheet as of December 31, 2023.   

Discontinued Operations

During the third quarter of 2022, we entered into an agreement to sell our GGB business and announced our intention to 

sell Garlock Pipeline Technologies, Inc. ("GPT").  These businesses, along with Compressor Products International ("CPI"), 
which was divested on December 21, 2021, comprised our entire Engineered Materials segment ("Engineered Materials"). As a 
result of classifying the GGB and GPT businesses as held for sale in the third quarter of 2022, we determined Engineered 
Materials to be a discontinued operation. 

On January 30, 2023 we completed the sale of GPT. In 2023, we received $28.9 million, net of transaction fees and cash 

sold, resulting in a pretax gain of $14.6 million recognized in the first quarter of 2023.

The sale of GGB closed on November 4, 2022 to The Timken Company. We received $298.2 million, net of transaction 
fees and cash sold, including $3.1 million of payments made in Q1 of 2023. We recorded a pre-tax gain of  $189.1 million as 
part of our discontinued operations in the fourth quarter of 2022.

The sale of GGB included a subsidiary of our Sealing Technologies segment which is not part of the discontinued 
operations described above. The results of operations of this subsidiary are included in continuing operations for all periods 
being reported. As a result of this sale, we recorded a $0.4 million loss in the fourth quarter of 2022 in other expense in our 
consolidated statement of operations.

On October 12, 2021, we entered into an Equity and Asset Purchase Agreement providing for the sale of specified equity 
interests and assets of CPI. The sale closed on December 21, 2021 and we recorded a pretax gain of $117.6 million in the fourth 
quarter of 2021 as a result of this transaction.

24

Unless otherwise indicated, amounts presented in Management's Discussion and Analysis of Financial Condition and 
Results of Operations pertain to continuing operations only (see Note 20 to our Consolidated Financial Statements in this Form 
10-K for information on discontinued operations and the related disposition of those operations)

Other Dispositions

On September 2, 2021, we sold certain assets and liabilities of our polymer components business unit, which was 
principally located in Houston, Texas and had been included in our Sealing Technologies segment. As a result of the sale, we 
recorded a pre-tax gain of $19.5 million in other income (expense) on our Consolidated Statements of Operations.

We measure segment 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 that was subject to reduction for certain types of employment 
terminations of the sellers. This expense was recorded in selling, general, and administrative expenses on our Consolidated 
Statements of Operations and is directly related to the terms of the acquisitions.  We acquired all of the LeanTeq non-
controlling interests in the fourth quarter of 2022 and all of the Alluxa non-controlling interests in the first quarter of 2024.

Other income (expense), net in the table above contains all items included in other (operating) expense and other income 

(expense) on our Consolidated Statements of Operations for the years ending December 31, 2023, 2022, and 2021 with the 
exception of $4.0 million, $1.9 million, and $2.4 million, respectively, of segment restructuring costs and $1.0 million, $1.1 
million and $0.1 million of corporate restructuring costs in 2023, 2022 and 2021, respectively. Additionally, other income 
(expense), net in the table above for the years ending December 31, 2023, 2022, and 2021 also includes $1.6 million, $(1.8) 
million, and $3.4 million, respectively, of miscellaneous expenses (credits) that are either not associated with a particular 
segment or not considered part of administering the corporate headquarters. These expenses are included in selling, general and 
administrative expense on our Consolidated Statements of Operations.

2023 Compared to 2022 

Sales of $1,059.3 million in 2023 decreased 3.6% from $1,099.2 million in 2022. The following table summarizes the

Following is a discussion of operating results for each segment during 2023 compared to 2022:

Sealing Technologies. Sales of $658.4 million in 2023 reflect a 5.5% increase compared to $624.3 million in 2022. 
Excluding favorable foreign exchange translation ($3.1 million) on our 2023 sales and the sales from businesses that have since 
been divested ($4.1 million) from 2022 results, sales were up 5.7% or $35.1 million. This increase was primarily driven by 
sales price actions partially offset by lower sales volume.  The sales volume decline in food and pharmaceuticals, commercial 
vehicle OEM, and general industrial was greater than the sales volume increase in aerospace and power generation.  

Segment AEBITDA of $192.3 million in 2023 increased 20.9% from $159.1 million in 2022. Segment AEBITDA margin 
increased from 25.5% in 2022 to 29.2% in 2023. Excluding the favorable foreign exchange translation ($1.6 million) from 2023 
results and the Segment AEBITDA earned from businesses that have since been divested ($1.9 million) from 2022 results, 
Adjusted Segment EBITDA increased 21.3%, or $33.5 million. The increase in Segment AEBITDA was driven primarily by 
pricing gains ($41.2 million) and favorable sales mix ($2.2 million), partially offset by increase in labor and overhead costs 
($5.3 million), decreased sales volume ($4.0 million), foreign exchange transaction related costs ($0.3 million), and higher 
segment selling, general, and administrative costs ($0.3 million).  

Advanced Surface Technologies. Sales of $401.2 million in 2023 reflect a 15.7% decrease compared to $476.1 million in 

2022. Excluding the unfavorable foreign exchange translation ($2.6 million) from 2023 results, sales were down (15.2)% or 
$(72.3) million. This decrease was driven primarily by the slowdown in the global semiconductor industry.

Segment AEBITDA of $95.5 million in 2023 decreased 32.5% from $141.5 million in 2022. Segment AEBITDA margin 

decreased from 29.7% in 2022 to 23.8% in 2023. Excluding the unfavorable impact of foreign exchange translation ($1.6 
million) from 2023 results, Segment AEBITDA was down 31.4% or $44.4 million. The decrease in Adjusted Segment EBITDA 
was driven primarily by lower volumes ($37.4 million), higher labor costs ($5.2 million), and a higher level of start-up 
expenses for LeanTeq's new production site in Arizona.

Corporate expenses for 2023 increased $2.5 million as compared to 2022. The increase was driven primarily by an 

increase in share-price-based long-term incentive compensation expenses ($5.5 million) as a result of our strong share price 
performance during 2023, partially offset by lower annual incentive compensation expense ($2.3 million) and decreased 
consulting related professional fees ($0.7 million).

Interest expense, net in 2023 decreased by $3.8 million as compared to 2022 primarily due to higher interest income 

earned on cash and short-term investment balances and the impact of lower average outstanding debt due to the repayment of 
Term Loan A-1 of $133.1 million on July 26, 2023, offset in part by higher interest rates on our variable rate term loan debt and 
lower receipts as a result of settling one of our cross currency swap agreements in 2022.

Other income (expense), net in 2023 increased by $2.3 million as compared to 2022, primarily due to higher non-service 

pension related costs ($5.1 million), decreased year-over-year foreign exchange gains ($4.8 million), and increased costs related 
to divested businesses ($1.4 million), partially offset by an asbestos receivable write-down in the prior-year period ($2.8 

27

million), decreased foreign exchange losses related to an intercompany note denominated in Euros ($1.6 million), lower 
environmental-related costs ($2.2 million), prior-year warranty costs related to a disposed product line ($0.7 million), a loss on 
the sale of a business in the prior year-period ($0.6 million), and a decrease in charges related to the reversal of a receivable 
related to an amount due from the sellers of Aseptic for uncertain tax positions that have passed the statute of limitations ($0.9 
million). An offsetting decrease in expense was recorded for the release of the corresponding liability for the uncertain tax 
position and is reflected as a reduction in tax expense. 

Income tax expense from continuing operations was $30.8 million in 2023 and $24.4 million in 2022. The effective tax 
rates for 2023 and 2022 were 81.6% and 86.2% respectively. The higher effective tax rate for both years was primarily driven 
by goodwill impairment, which is not deductible for income taxes, the foreign rate differential related to certain foreign 
earnings that were subject to higher tax rates, and releasing valuation allowances on certain tax attributes. In 2023, we had an 
increased tax expense relative to 2022, primarily driven by higher pre-tax earnings and the net impact of a legal entity 
restructuring. 

Goodwill impairment expense of $60.8 million and $65.2 million was incurred in 2023 and 2022, respectively, related to 

the Alluxa reporting unit. No goodwill impairment expense was incurred in 2021. 

Income from continuing operations attributable to Enpro Inc. was $10.8 million, or $0.52 per share, in 2023 compared to 

income from continuing operations attributable to Enpro Inc. of $6.7 million, or $0.32 per share, in 2022. 

2022 Compared to 2021 

For a comparison of our results of operations for the years ended December 31, 2022 to December 31, 2021, see "Part II, 

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" of the Company's Annual 
Report on Form 10-K for the fiscal year ended December 31, 2022, filed with the SEC on March 1, 2023. 

Restructuring and Other Costs

We incurred $5.0 million, $3.0 million and $2.5 million of restructuring and impairment costs during the years ended 
December 31, 2023, 2022 and 2021, respectively. Additionally, in 2023 and 2022, we incurred goodwill impairment charges of 
$60.8 million and $65.2 million, respectively, related to the Alluxa reporting unit. No goodwill impairment expense was 
incurred in 2021.

Of the restructuring and impairment costs incurred in 2023 and 2022, we incurred $4.3 million and $1.8 million, 

respectively, of restructuring costs related to the reorganization of sites and functions, primarily in the United States and 
$0.7 million and $1.2 million, respectively, of non-cash impairment charges of long-lived assets. Workforce reductions 
associated with our restructuring activities in 2023 and 2022 totaled 72 and 25 administrative and manufacturing positions, 
respectively. 

During 2021, we conducted a number of  restructuring activities throughout our operations which  mostly comprised of 

targeted workforce reductions. All costs associated with such initiatives were incurred in 2021. Workforce reductions associated 
with our restructuring activities totaled 36 administrative and manufacturing positions. 

Please see the "Overview" section of Management's Discussion and Analysis of Financial Condition and Results of 

Operations and Note 3 to our consolidated financial statements for further information.

Liquidity and Capital Resources

Cash requirements for, but not limited to, working capital, capital expenditures, acquisitions, and debt repayments have 

been funded from cash balances on hand, revolver borrowings and cash generated from operations. We are proactively pursuing 
acquisition opportunities. Should we need additional capital, we have resources available, which are discussed in this section 
under the heading “Capital Resources.”

As of December 31, 2023, we held $214.1 million of cash and cash equivalents in the United States and $155.7 million of 
cash outside of the United States. The acquisition of AMI on January 29, 2024 for $210 million was funded with cash available 
in the United States. If the funds held outside the United States were needed for our operations in the U.S., we have several 
methods to repatriate such funds without significant adverse tax effects, including repayment of intercompany loans, 
distributions subject to a 100-percent dividends-received deduction for income tax purposes, or distributions of previously-
taxed earnings. 

28

Because of the transition tax, GILTI, and Subpart F provisions, undistributed earnings of our foreign subsidiaries totaling 

$251.0 million at December 31, 2022 have been subjected to U.S. income tax or are eligible for the 100-percent dividends-
received deduction under Section 245A of the Internal Revenue Code ("IRC") provided in the Tax Cuts and Jobs Act. 
Additionally, undistributed earnings are estimated to be $179.5 million as of December 31, 2023. Whether through the 
application of the 100-percent dividends received deduction, or distribution of these previously-taxed earnings, we do not 
intend to distribute foreign earnings that will be subject to any significant incremental U.S. or foreign tax. During 2023, we 
repatriated $72.6 million of earnings from our foreign subsidiaries, resulting in only $0.4 million of withholding taxes net of 
refunds to be received. We have determined that estimating any tax liability on our investment in foreign subsidiaries is not 
practicable. Therefore, we have not recorded any deferred tax liability on undistributed earnings of foreign subsidiaries. 

Cash Flows

Operating activities of continuing operations provided cash in the amount of $208.4 million, $106.1 million and $124.1 

million in 2023, 2022 and 2021, respectively. The increase in operating cash flows in 2023 versus 2022 was primarily 
attributable to less income tax payments, net of refunds ($63.6 million) and improvements in net working capital. Higher tax 
payments in 2022 were the result of high proceeds from our divestiture of discontinued operations. The decrease in operating 
cash flow in 2022 versus 2021 was primarily attributable to increased income tax payments ($74.4 million) primarily related a 
refund from the IRS received in 2021 as a result of the conclusion of an audit of our 2014 through 2017 U.S. federal income tax 
returns and higher tax payments related to the divestiture of discontinued operations. These increases were partially offset 
higher sales volume.

Investing activities of continuing operations used $7.4 million in 2023, provided $268.6 million in 2022, and used $647.4 

million of cash in 2021. Investing activities in 2023 used cash primarily for investments in property, plant, and equipment 
($33.9 million), partially offset by proceeds of the sale of businesses, principally the sale of GPT ($25.9 million).  Investing 
activities in 2022 provided cash from the sale of businesses ($301.9 million), primarily the sale of GGB, and the settlement of 
derivative contracts ($27.4 million). This was partially offset by the payments for acquisitions, driven by the acquisition of the 
equity interests in LeanTeq held by the LeanTeq Executives ($31.2 million) and investments in property, plant and equipment 
($29.4 million).  The cash used in 2021 was primarily the result of the acquisition of NxEdge ($856.8 million), partially offset 
by proceeds from the divestiture of CPI and other businesses during the year ($224.3 million).  

Financing activities of continuing operations used $170.9 million in cash in 2023, primarily attributable to payments on 
our Term Loan Facilities, including the complete repayment of our Term Loan A-1 Facility, as defined and discussed below, 
($144.9 million) and by dividend payments ($24.3 million). Financing activities of continuing operations provided $368.0 
million in 2022 primarily attributable to a net payment our Revolving Credit Facility, as defined below, and Term Loan 
Facilities ($337.0 million) and by dividend payments ($23.4 million).  Financing activities provided $618.2 million in 2021, 
primarily attributable to a net draw on our revolving credit facility ($175.0 million), new Term Loan Facilities, as discussed 
below, ($465.0 million), and issuance of common stock ($10.0 million), partially offset by dividend payments ($22.4 million) 
and principal payments to our existing Term Loan A-1 Facility ($3.8 million).

Capital Resources

Senior Secured Credit Facility. On December 17, 2021, we entered into a Third Amended and Restated Credit Agreement 

(the “Amended Credit Agreement”) dated as of December 17, 2021 among the Company and EnPro Holdings, as borrowers, 
certain of our foreign subsidiaries are 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 Term Loan A-1 Facility and the Term Loan A-2 Facility, the "Term Loan Facilities”, which together with the 
Revolving Credit Facility are referred to as 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.

29

Borrowings under the 364-Day Facility bore interest at an annual rate of LIBOR plus 1.50% or base rate plus 0.50%.  

Initially, borrowings under the Facilities (other than the 364-Day Facility) bore interest at an annual rate of LIBOR plus 1.75% 
or base rate plus 0.75%, although these interest rates were subject to incremental increase or decrease based on a consolidated 
total net leverage ratio.  On November 8, 2022, we entered into a First Amendment to the Amended Credit Agreement, which 
replaced the LIBOR-based interest rate option with an option based on Term SOFR ("Secured Overnight Financing Rate")  plus 
(i) a credit spread adjustment of 0.10% and (ii) 1.75%, again subject to incremental increase or decrease based on a 
consolidated total net leverage ratio.  In addition, a commitment fee accrues with respect to the unused amount of the Revolving 
Credit Facility at an annual rate of 0.225%, which rate is also subject to incremental increase or decrease based on a 
consolidated total net leverage ratio.

The Term Loan A-1 Facility amortized 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 amortizes 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 did not amortize and was 
repaid in full in the quarter ended September 30, 2022. The Facilities are subject to prepayment with the net cash proceeds of 
certain asset sales not reinvested in acquisitions within a specified period, casualty or condemnation events, and non-permitted 
debt issuances. On July 21, 2023, we entered into a waiver agreement under Amended Credit Agreement that waived the 
requirement to prepay the Facilities with remaining excess net cash proceeds related to the sale of GGB and GPT that had not 
been reinvested in operating assets within 365 days from the date of the sale. In conjunction with this waiver, on July 26, 2023, 
we voluntarily prepaid all outstanding borrowings and accrued and unpaid interest under the Term Loan A-1 Facility (a 
remaining principal balance of $133.1 million and accrued interest of $0.6 million). After taking into account the repayment of 
borrowings under the Term Loan A-1 Facility noted above, forecasted capital expenditures, and other applicable expenditures, 
we expect to meet all reinvestment requirements under the indenture related to the excess net cash proceeds from the sales of 
GGB and GPT. There is no prepayment penalty for a full or partial repayment of the Facilities at any time. 

The Company and EnPro Holdings are the permitted borrowers under the Facilities.  We have the ability to add wholly 

owned foreign subsidiaries as borrowers under the Revolving Credit Facility.  Each of our domestic, consolidated subsidiaries 
(other than any subsidiaries that may be designated as "unrestricted" by the Company from time to time an inactive 
subsidiaries) is required to guarantee the obligations of the borrowers under the Facilities, and each of our existing domestic, 
consolidated 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 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 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 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 decreased, may be increased (up to three times) at the borrowers' option to not more than 4.5 to 1.0 
for the for-quarter period following a significant acquisition; and

•

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

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:

30

•

•

grant liens on our assets;

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

• make certain investments (including loans and advances);

• merge or make other fundamental changes;

•

•

sell or otherwise dispose of property or assets;

pay dividends and other distributions and prepay certain indebtedness;

• make changes in the nature of our business;

•

•

enter into transactions with our affiliates;

enter into burdensome contracts; and

• modify or terminate documents related to certain indebtedness.

We were in compliance with all covenants of the Amended Credit Agreement as of December 31, 2023. The borrowing 

availability under our Revolving Credit Facility at December 31, 2023 was $390 million after giving consideration to $10.0 
million of outstanding letters of credit. The balance of our outstanding Term Loan A-2 Facility at December 31, 2023 was 
$299.3 million. 

Senior Notes. On October 17, 2018, we completed the offering of $350 million aggregate principal amount of our 5.75% 

senior notes due 2026 (the "Senior Notes") and applied the net proceeds of that offering, together with borrowings under the 
Revolving Credit Facility, to redeem on October 31, 2018 the full $450 million aggregate principal amount of our outstanding 
5.875% senior notes due 2022. 

The 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.

Commencing on October 15, 2021, we may, on any one or more occasions, redeem all or a part of the Senior Notes at 

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

Each holder of the Senior Notes may require us to repurchase some or all of the Senior Notes held by such holder for cash 

upon the occurrence of a defined “change of control” event. Our ability to redeem the Senior Notes prior to maturity is subject 
to certain conditions, including in certain cases the payment of make-whole amounts.

The indenture governing the Senior Notes requires us to apply the net cash proceeds of certain asset sales not reinvested 
in acquisitions, capital expenditures, or used to repay or otherwise reduce specified indebtedness within a specified period, to 
the extent the remaining net proceeds exceed a specified amount, to offer to repurchase the Senior Notes at a price equal to 
100% of the principal amount thereof plus accrued and unpaid interest.

The payments for long-term debt shown in the table above reflect the contractual principal amount for the Senior Notes 
and term loans under our Amended Credit Agreement. In our Consolidated Balance Sheet, these amounts are shown net of a 
debt discount of $3.3 million.  Additional discussion regarding the Senior Notes and Amended Credit Agreement is included in 
this Management’s Discussion and Analysis of Financial Condition and Results of Operations in “Liquidity and Capital 
Resources – Capital Resources,” and in Note 11, "Debt," to the consolidated financial statements. The interest on debt 
represents the contractual interest coupon. It does not include the debt discount accretion, which also is a component of interest 
expense.

The estimated payments of environmental liabilities is based on information currently known to us. However, it is 

possible that these estimates will vary from actual results and it is possible that these estimates may be updated if new 
information becomes available in the future or if there are changes in the facts and circumstances related to these liabilities. 
Additional discussion regarding these liabilities is included earlier in this Management’s Discussion and Analysis of Financial 
Condition and Results of Operations in “Contingencies – Environmental"  and "Contingencies – Crucible Steel Corporation a/k/
a Crucible, Inc.,” and in Note 19, "Commitments and Contingencies," to the consolidated financial statements.

The table does not include obligations under our pension plans, which is included in Note 14, "Pension," to the 

consolidated financial statements.

Share Repurchase Program

In October 2022, our board of directors renewed their authorization for a new two-year program of up to $50.0 million 

for the repurchase of our outstanding common shares. We have not made any repurchases for the three-year period ended 
December 31, 2023.

Dividends

On January 13, 2015, our board of directors adopted a policy under which it intends to declare regular quarterly cash 
dividends on Enpro’s common stock, with the determination of whether to declare a dividend and the amount being considered 
each quarter, after taking into account our cash flow, earnings, cash position, financial position and other relevant matters. In 
2021, our board declared a dividend of $0.27 per share in each quarter, in 2022, our board declared a dividend of $0.28 per 
share in each quarter, and in 2023 our board declared a dividend of $0.29 per share in each quarter. On February 15, 2024 we 
announced that our board of directors had increased the quarterly dividend to $0.30 per share, commencing with the dividend to 
be paid on March 20, 2024 to all shareholders of record as of March 6, 2024. Each of the Credit Agreement and the indenture 
governing the Senior Notes includes covenants restricting the payment of dividends, but includes a basket permitting the 
payment of cash dividends of up to $50.0 million per year under the Credit Agreement and $60.0 million per year under the 
indenture governing the Senior Notes.  Other baskets may be available under that the agreement governing the Revolving 
Credit Facility and the indenture governing the Senior Notes to permit the payment of dividends in excess of the respective 
basket amount.

Critical Accounting Estimates

The preparation of our Consolidated Financial Statements, in accordance with accounting principles generally accepted in 

the United States, requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues 
and expenses, and related disclosures pertaining to contingent assets and liabilities. Note 1, “Overview, Basis of Presentation, 
Significant Accounting Policies and Recently Issued Accounting Guidance,” to the Consolidated Financial Statements describes 

32

the significant accounting policies used to prepare the Consolidated Financial Statements and recently issued accounting 
guidance. On an ongoing basis we evaluate our estimates, including, but not limited to, those related to bad debts, inventories, 
intangible assets, income taxes, warranty obligations, restructuring, pensions, and contingencies and litigation. We base our 
estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances. 
Actual results may differ from our estimates.

We believe the following accounting estimates are the most critical. Some of them involve significant judgments and 

uncertainties and could potentially result in materially different results under different assumptions and conditions.

Goodwill and Other Intangible Assets

Goodwill represents the excess of the purchase price over the estimated fair value of the net assets of acquired businesses. 
Goodwill is not amortized, but instead is subject to annual impairment testing that is conducted each calendar year in the fourth 
quarter. Our annual impairment testing for all of our intangible assets is November 1 of each year.    

The goodwill asset impairment test involves comparing the fair value of a reporting unit to its carrying amount. An 
impairment charge is recognized when the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized 
would not exceed the total amount of goodwill allocated to that reporting unit. Interim tests during the year may be required if 
an event occurs or circumstances change (a "triggering event") that in management's judgement would more likely than not 
reduce the fair value of a reporting unit below its’ carrying amount.

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

At the time of our annual test as of November 1, 2022, our updated forecast and projections based upon our annual 
projection and analysis indicated that the carrying value of the Alluxa reporting unit exceeded fair value by $65.2 million which 
has been recognized as an impairment charge in the fourth quarter of 2022. This was primarily driven by the increase in 
discount rate from 12.0% as of November 1, 2021 to 14.6% as of November 1, 2022. In the second quarter of 2023, we 
determined the lower than previously projected actual and forecasted financial performance of our Alluxa reporting unit to be a 
triggering event for an interim goodwill impairment test. We determined the carrying value of our Alluxa reporting unit to 
exceed its fair value and, as a result, we impaired the remaining $60.8 million of goodwill related to Alluxa.  Our Consolidated 
Balance Sheet at December 31, 2023 reflects no goodwill related to Alluxa. 

The fair value of our semiconductor reporting unit, included in the Advanced Surface Technologies segment, exceeded 
carrying value by approximately 20% as of November 1, 2023. The carrying value of the Semiconductor reporting unit as of 
December 31, 2023 includes $532.2 million of goodwill. In the second quarter of 2023, we determined the lower than 
previously projected actual and forecasted financial performance of our Semiconductor reporting unit to be a triggering event 
for an interim goodwill impairment test. We determined the fair value exceeded the carrying value as of June 30, 2023. Our 
Semiconductor reporting unit's value increased from our interim test as of June 30, 2023 due to further progression in our 
growth initiatives for the reporting unit. We considered the sensitivity of the valuation of our Semiconductor reporting unit to 
adverse changes in our projected cash flows under three separate alternative scenarios. First, with a 5% reduction in forecasted 
sales used in our valuation model, we estimate the fair value of the Semiconductor reporting unit would exceed its carrying 
value by approximately 12%. Second, with a 1% increase in the discount rate as of November 1, 2023 we estimate our fair 
value of the Semiconductor reporting unit would exceed its carrying value by approximately 9%. For the third scenario, the 
combination of a 1% increase in discount rate and 5% reduction in forecasted sales would result in the fair value of our 
Semiconductor reporting unit approximating the carrying value. All annual and interim impairment tests of goodwill for the 
Semiconductor reporting unit performed during the 3-years ended December 31, 2023 indicated there was no impairment of 
goodwill for the Semiconductor reporting unit.       

The fair value of the three reporting units of our Sealing Technologies segment all exceeded their respective carrying 

values by more than 75% as of November 1, 2023.  Our annual impairment test of the goodwill for the three reporting units of 
our Sealing Technologies segment as of November 1, 2022 and 2021 indicated no impairment.

33

Annual assessments are conducted in the context of information that was reasonably available to us as of the date of the 

assessment including our best estimates of future sales volumes and prices; material and labor cost and availability; operational 
efficiency including the impact of projected capital asset additions, and the discount rates and tax rates. We will perform our 
next annual goodwill impairment tests as of November 1, 2024; or earlier, if adverse changes in circumstances result in our 
assessment that a triggering event has occurred at any of our reporting units and an interim test is required.       

Other intangible assets are recorded at cost or, when acquired as a part of a business combination, at estimated fair value. 
These assets include customer relationships, patents and other technology-related assets, trademarks, licenses, and non-compete 
agreements. Intangible assets that have definite lives are amortized using a method that reflects the pattern in which the 
economic benefits of the assets are consumed or the straight-line method over estimated useful lives of 1 to 21 years. Intangible 
assets with indefinite lives, which consist primarily of trade names, are subject to at least annual impairment testing, which was 
conducted as of November 1 in 2023, 2022 and 2021. The impairment testing compares the fair value of the intangible asset 
with its carrying amount using the relief from royalty method. The testing completed as of November 1, 2023, 2022 and 2021, 
indicated no impairment.  Interim tests may be required if an event occurs or circumstances change that would more likely than 
not reduce the fair value below the carrying value or change the useful life of the asset. 

Many of the factors used in assessing fair value are outside the control of management, and it is reasonably likely that 

assumptions and estimates will change in future periods. These changes could result in future impairments. For additional 
information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Overview” as 
well as Notes 1 and 8 to the Consolidated Financial Statements.

Environmental

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.

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. In general, due to uncertainties regarding, among other factors, changes 
to operating and monitoring requirements based on the ongoing performance of the remediation system and/or changes to 
applicable legal and regulatory requirements, we do not consider costs for remediation activities beyond five years to be 
reasonably estimable. To the extent that capital costs to be incurred more than five years out, such as costs for the construction 
or decommissioning of remediation systems, can be reasonable estimated such costs are included in our environmental reserves. 
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 our 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. 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. 

Income Taxes

We use the asset and liability method of accounting for income taxes. Temporary differences arising between the tax 

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

34

we believe is greater than 50 percent likely to be realized is recorded. Our future results may include favorable or unfavorable 
adjustments to our estimated tax liabilities due to closure of income tax examinations, statute expirations, new regulatory or 
judicial pronouncements, changes in tax laws, changes in projected levels of taxable income, future tax planning strategies, or 
other relevant events.

OECD/G20 Base Erosion and Profit Shifting Project - Pillar 2

The Organization for Economic Co-operation and Development (the “OECD”) has introduced a framework to implement 

a global minimum corporate tax of 15%, referred to as Pillar Two. While it is uncertain whether the U.S. will enact legislation 
to adopt Pillar 2, certain countries in which we operate have adopted legislation, and other countries are in the process of 
introducing legislation to implement Pillar 2, which is to be effective for tax years beginning in 2024. Based on the currently 
issued guidance by the OECD we do not expect Pillar 2 to have a material impact on our effective tax rate in the year of 
adoption or in subsequent years. As the OECD continues to release additional guidance and countries implement legislation, we 
are monitoring developments and evaluating the impacts these new rules will have on our tax rate, including eligibility to 
qualify for safe harbor rules.

Contingencies

A description of our contingencies is included in Note 19 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 existing and future 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 December 31, 2023 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 table above reflects $9.6 million of current intercompany receivables due to the Guarantor Subsidiaries from the Non-

Guarantor Subsidiaries and $8.6 million of current intercompany payables due to the Non-Guarantor Subsidiaries from the 
Guarantor Subsidiaries within current assets and liabilities held and used. 

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 

36

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 
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

Reconciliation of Adjusted Income from Continuing Operations Attributable to Enpro Inc.

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 income from continuing operations attributable to Enpro Inc. and diluted earnings per share attributable to 
Enpro Inc. continuing operations, 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.

Adjustments in the tables above only reflect amounts attributable to Enpro Inc. 

1 Non-controlling interest compensation allocation represents compensation expense associated with a portion of the 
rollover equity from the acquisitions of LeanTeq and Alluxa that was 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 acquisition. We acquired all 
of the LeanTeq non-controlling interests in the fourth quarter of 2022 and all of the Alluxa non-controlling interests in the first 
quarter of 2024.

2 In connection with the acquisition of Aseptic in 2019, we recognized a liability for uncertain tax positions and a related 

indemnification asset for the portion of that liability recoverable from the seller. We determined the statute of limitations 
expired on some of the uncertain tax positions in 2021 and 2022 and, accordingly, removed a portion of the liability and 
receivable. The release of the related liability was recorded as part of our tax expense for the year ended December 31, 2021 
and December 31, 2022 and the reversal of the related receivable was recorded as an expense in other non-operating income 
(expense) on our consolidated statement of operations. 

3In connection with the sale of GGB, accounted for as a discontinued operation, in the fourth quarter of 2022, we issued 

an intercompany note between a domestic and foreign entity that was denominated in a foreign currency. As a result of this 
note, we recorded a loss due to the change in exchange rate during December 2022. In January 2023, we hedged the outstanding 
notes and expect future gains or losses to be minimal.

4 Other adjustments are included in selling, general, and administrative, cost of sales, and other operating expenses on the

5Adjusted diluted earnings per share.

The adjusted income tax expense presented above is calculated using a normalized company-wide effective tax rate 
excluding discrete items of 25.0% for 2023, 27.0% for 2022, and 30.0% for 2021. Per share amounts were calculated by 
dividing by the weighted-average shares of diluted common stock outstanding during the periods.

ITEM 7A.

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 affect our financial condition, results of operations and cash flows. 
We manage our exposure to these and other market risks through normal 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.

Interest Rate Risk

We are exposed to interest rate risk as a result of our outstanding debt obligations. The table below provides information 

about the maturities of our fixed rate debt obligations as of December 31, 2023. The table represents principal cash flows (in 
millions) and related weighted average interest rates by the contractual maturity dates.

The table above excludes unamortized debt discount of $2.1 million at December 31, 2023.

Additionally, we had $299.3 million outstanding on the Amended Credit Agreement as of December 31, 2023, which has 
a variable interest rate that adjusts at least quarterly. A change in interest rates on variable-rate debt affects the interest expense 
incurred and cash flows, but does not affect the net balance sheet liability of the financial instrument. 

Foreign Currency Risk

We are exposed to foreign currency risks arising 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. In December 2022, we entered into a forward contract to hedge a 95 million Euro 
exposure of an intercompany note agreement related to the proceeds from the GGB sale allocated to foreign subsidiaries. We 
expect this position to be resolved in 2024. The notional amount of foreign exchange contracts hedging foreign currency 
transactions was $110.5 million and $103.3 million as of December 31, 2023 and 2022, respectively. All foreign exchange 
contracts outstanding at December 31, 2023 expired in January 2024. 

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, which could have a negative impact on our results. We strive to pass along such 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.

CONTROLS AND PROCEDURES

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”)).  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 in the SEC's rules and forms, and that such information is 
accumulated and communicated to our management, including our chief executive officer and chief financial officer, as 
appropriate to allow timely decisions regarding required disclosure.

Based on the controls evaluation, our chief executive officer and chief financial officer have concluded that our disclosure 
controls and procedures were effective as of December 31, 2023 to provide reasonable assurance 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 such information is accumulated and communicated to management, including its chief executive officer and 
chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as 

such term is defined in Rule 13a-15(f) under the Exchange Act. Our internal control over financial reporting is a process 
designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial 
statements for external purposes in accordance with generally accepted accounting principles. 

We carried out an evaluation, under the supervision and with the participation of our chief executive officer and our chief 

financial officer, of the effectiveness of our internal control over financial reporting as of the end of the period covered by this 
report. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway 
Commission (COSO) in the Internal Control-Integrated Framework (2013). Based on our assessment, we have concluded, as 
of December 31, 2023, our internal control over financial reporting was effective based on those criteria.

The effectiveness of our internal control over financial reporting as of December 31, 2023, has been audited by 

PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears in this 
Annual Report on Form 10-K.

42

Management does not expect our disclosure controls and procedures or internal controls to prevent all errors and all 

fraud. A control system, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that 
the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource 
constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all 
control systems, no evaluation of controls can provide absolute assurance all control issues and instances of fraud, if any, within 
the company have been detected. These inherent limitations include the realities that judgments in decision-making can be 
faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual 
acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system 
of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance any 
design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become 
inadequate because of changes in conditions or deterioration in the degree of compliance with polices or procedures. Because of 
the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. 
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate.

Changes in Internal Control Over Financial Reporting

There were no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under 

the Exchange Act) that occurred during the quarter ended December 31, 2023 that materially affected, or that are reasonably 
likely to materially affect, our internal control over financial reporting. 

ITEM 9B.

OTHER INFORMATION

During 2023, none of the Company’s directors or officers (as defined in Rule 16a-1(f) of the Exchange Act) adopted or 

terminated a “Rule 10b5-1 trading arrangement” or a “non-Rule 10b5-1 trading arrangement” (as such terms are defined in Item

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of Enpro Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Enpro Inc. and its subsidiaries (the “Company”) as of 
December 31, 2023 and 2022, and the related consolidated statements of operations, of comprehensive income, of changes in 
shareholders' equity and of cash flows for each of the three years in the period ended December 31, 2023, including the related 
notes and financial statement schedule listed in the index appearing under Item 15(a)(2) (collectively referred to as the 
“consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of 
December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial 
position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the 
three years in the period ended December 31, 2023 in conformity with accounting principles generally accepted in the United 
States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over 
financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) 
issued by the COSO.

Basis for Opinions

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

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

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

Definition and Limitations of Internal Control over Financial Reporting

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

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

Critical Audit Matters

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

Interim and Annual Goodwill Impairment Tests – Alluxa and Semiconductor Reporting Units 

As described in Notes 1 and 8 to the consolidated financial statements, the Company’s consolidated goodwill balance was 
$808.4 million as of December 31, 2023, and the goodwill associated with Alluxa and Semiconductor reporting units was $0 
and $532.2 million, respectively. Goodwill is not amortized, but instead is subject to impairment testing that is conducted at 
least annually each calendar year in the fourth quarter. Interim tests during the year may be required if an event occurs or 
circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The 
goodwill asset impairment test involves comparing the fair value of a reporting unit to its carrying amount. An impairment 
charge is recognized when the carrying amount exceeds the reporting unit’s fair value. The loss recognized would not exceed 
the total amount of goodwill allocated to the reporting unit. In the second quarter of 2023, management determined the lower 
than previously projected actual and forecasted financial performance of the Alluxa and Semiconductor reporting units was a 
triggering event for interim goodwill impairment tests. Management determined the carrying value of the Alluxa reporting unit 
exceeded its fair value, and as a result, impaired the remaining $60.8 million of goodwill that was related to the Alluxa 
reporting unit. Both the annual and interim impairment tests of goodwill for the Semiconductor reporting unit indicated there 
was no impairment of goodwill. To estimate the fair value of the reporting units, management uses both a discounted cash flow 
and a market valuation approach. The key assumptions used for the discounted cash flow and market valuation approaches 
include projected revenues and profit margins, projected capital expenditures, changes in working capital, the discount rates, the 
tax rates, and market multiples of similar companies.   

The principal considerations for our determination that performing procedures relating to the interim and annual goodwill 

impairment tests of the Alluxa and Semiconductor reporting units is a critical audit matter are (i) the significant judgment by 
management when developing the fair value estimates of the Alluxa and Semiconductor reporting units; (ii) a high degree of 
auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions 
related to projected revenues and profit margins for the Alluxa reporting unit as of the interim goodwill impairment test, 
projected revenues, profit margins, and the discount rate for the Semiconductor reporting unit as of the interim goodwill 
impairment test, and projected revenues and profit margins for the Semiconductor reporting unit as of the annual goodwill 
impairment test; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our 
overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating 
to management’s goodwill impairment tests, including controls over the valuation of the Alluxa and Semiconductor reporting 
units. These procedures also included, among others (i) testing management’s process for developing the fair value estimates of 
the Alluxa and Semiconductor reporting units; (ii) evaluating the appropriateness of the discounted cash flow approach used by 
management; (iii) testing the completeness and accuracy of underlying data used in the discounted cash flow approach; and (iv) 
evaluating the reasonableness of the significant assumptions used by management related to projected revenues, profit margins, 
and the discount rate. Evaluating management’s assumptions related to projected revenues and profit margins involved 
evaluating whether the assumptions used by management were reasonable considering (i) the current and past performance of 
the Alluxa and Semiconductor reporting units; (ii) the consistency with external market and industry data; and (iii) whether the 
assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and 
knowledge were used to assist in evaluating (i) the appropriateness of the discounted cash flow approach and (ii) the 
reasonableness of the discount rate assumption.

ENPRO INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Overview, Basis of Presentation, and Significant Accounting Policies

Overview

Enpro Inc. (“we,” “us,” “our,” “Enpro,” or the “Company”) is a leading-edge industrial technology company focused on 

critical applications across a diverse group of growing end markets such as semiconductor, industrial process, commercial 
vehicle, sustainable power generation, aerospace, food and pharmaceutical, photonics and life sciences. The Company is a 
leader in applied engineering and designs, develops, manufactures, and markets proprietary, value-added products and solutions 
that contribute key functionality or safeguard a variety of critical environments.

Over the past several years, we have executed several strategic initiatives to focus the portfolio of businesses where we 
offer proprietary, industrial technology-related products and solutions with high barriers to entry, compelling margins, strong 
cash flow, and perpetual recurring/aftermarket revenue streams in markets with favorable secular tailwinds. 

Basis of Presentation

The Consolidated Financial Statements reflect the accounts of the Company and our majority-owned and controlled 

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

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 
of America ("GAAP") requires management to make estimates and assumptions that affect the amounts 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. Actual results could differ from those estimates.

Summary of Significant Accounting Policies

Revenue Recognition – The largest stream of revenue is product revenue for shipments of the various products discussed 
further in Note 18, "Business Segment Information," along with a smaller amount of revenue from services that typically take 
place over a short period of time.  We recognize revenue at a point in time following the transfer of control, which typically 
occurs when a product is shipped or delivered, depending on the terms of the sale agreement, or when services are rendered.  
Shipping costs billed to customers are recognized as revenue and expensed in cost of goods sold as a fulfillment cost when 
control of the product transfers to the customer.  Payment from customers is typically due within 30 days of the sale for sales in 
the U.S.  For sales outside of the U.S., payment terms may be longer based upon local business customs, but are typically due 
no later than 90 days after the sale. 

Redeemable Non-Controlling Interests – Non-controlling interests in subsidiaries that are redeemable for cash or other 
assets outside of our control are classified as mezzanine equity, outside of equity and liabilities, at the greater of the carrying 
value or the redemption value. The increases or decreases in the estimated redemption amount are recorded with corresponding 
adjustments against equity and are reflected in the computation of earnings per share. At December 31, 2023, the redeemable 
non-controlling interest relates solely to Alluxa.

Foreign Currency Translation – The financial statements of those operations whose functional currency is a foreign 
currency are translated into U.S. dollars using the current rate method. Under this method, all assets and liabilities are translated 
into U.S. dollars using current exchange rates, and income statement activities are translated using average exchange rates. The 
foreign currency translation adjustment is included in accumulated other comprehensive income (loss) in the Consolidated 
Balance Sheets. Gains and losses on foreign currency transactions are included in operating income. Foreign currency 
transaction losses (gains) totaled $1.3 million, $(4.8) million, and $1.7 million, respectively, in 2023, 2022, and 2021. In 
addition to these transaction losses (gains), we recorded $2.2 million and $3.8 million, respectively, in 2023 and 2022 of foreign 
currency transaction losses in other non-operating expense. These losses resulted from an intercompany note between a 
domestic and foreign subsidiary, related to the divestiture of discontinued operations, that was denominated in a foreign 
currency.

Research and Development Expense – Costs related to research and development activities are expensed as incurred. We 

perform research and development primarily under company-funded programs for commercial products. Research and 
development expenditures in 2023, 2022, and 2021 were $9.5 million, $10.1 million, and $9.8 million, respectively, and are 
included in selling, general and administrative expenses in the Consolidated Statements of Operations.

59

Income Taxes – We use the asset and liability method of accounting for income taxes. Temporary differences arising 

between the tax basis of an asset or liability and its carrying amount on the Consolidated Balance Sheet are used to calculate 
future income tax assets or liabilities. This method also requires the recognition of deferred tax benefits, such as net operating 
loss carryforwards. Valuation allowances are recorded as appropriate to reduce deferred tax assets to the amount considered 
likely to be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to the taxable 
income (losses) in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred 
tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the date of enactment of the 
change. A tax benefit from an uncertain tax position is recognized only if we believe it is more likely than not that the position 
will be sustained on its technical merits. If the recognition threshold for the tax position is met, only the portion of the tax 
benefit that we believe is greater than 50 percent likely to be realized is recorded. Our future results may include favorable or 
unfavorable adjustments to our estimated tax liabilities due to closure of income tax examinations, statute expirations, new 
regulatory or judicial pronouncements, changes in tax laws, changes in projected levels of taxable income, future tax planning 
strategies, or other relevant events.

The Tax Cuts and Jobs Act (the "Tax Act") provides for a territorial tax system, that includes the global intangible low-

taxed income (“GILTI”) provision beginning in 2018. The GILTI provisions require us to include in our U.S. income tax return 
certain current year foreign subsidiary earnings net of foreign tax credits, subject to limitation. We elected to account for the 
GILTI tax in the period in which it is incurred. 

Cash and Cash Equivalents – Cash and cash equivalents include cash on hand, demand deposits and highly liquid 

investments with a maturity of three months or less at the time of purchase.

Receivables – Accounts receivable are stated at the historical carrying amount net of write-offs and allowance for 
doubtful accounts. We establish an allowance for doubtful accounts receivable based on historical experience and any specific 
customer collection issues we have identified. Doubtful accounts receivable are written off when a settlement is reached for an 
amount less than the outstanding historical balance or when we have determined the balance will not be collected.

Inventories –   Inventories are valued using the first-in, first out ("FIFO") cost method and are recorded at the lower of 

cost or net realizable value. 

Property, Plant and Equipment – Property, plant and equipment are recorded at cost. Depreciation of plant and 
equipment is determined on the straight-line method over the following estimated useful lives of the assets: buildings and 
improvements, 5 to 25 years; machinery and equipment, 3 to 10 years.

Goodwill and Other Intangible Assets – Goodwill represents the excess of the purchase price over the estimated fair value 
of the net assets of acquired businesses. Goodwill is not amortized, but instead is subject to impairment testing that is conducted 
at least annually each calendar year in the fourth quarter. Our annual impairment testing for all of our intangible assets is 
November 1 of each year.

The goodwill asset impairment test involves comparing the fair value of a reporting unit to its carrying amount. An 
impairment charge is recognized when the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized 
would not exceed the total amount of goodwill allocated to that reporting unit. Interim tests during the year may be required if 
an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its 
carrying amount.

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

At the time of our annual test as of November 1, 2022, our updated forecast and projections based upon our annual 

strategic plan indicated that the Alluxa reporting unit’s carrying value exceeded fair value by $65.2 million which was 
recognized as an impairment charge in the fourth quarter of 2022. The discount rate to determine the fair value of Alluxa 
increased from 12.0% as of November 1, 2021 to 14.6% as of November 1, 2022. In the second quarter of 2023, we determined 
the lower than previously projected actual and forecasted financial performance of our Alluxa reporting unit to be a triggering 
event for an interim goodwill impairment test. We determined the carrying value of our Alluxa reporting unit to exceed its fair 

60

value and, as a result, we impaired the remaining $60.8 million of goodwill related to Alluxa. Our Consolidated Balance Sheet 
at December 31, 2023 reflects no goodwill related to Alluxa. 

The fair value of our semiconductor reporting unit, included in the Advanced Surface Technologies segment, exceeded 
carrying value by approximately 20% as of November 1, 2023. The carrying value of the Semiconductor reporting unit as of 
December 31, 2023 includes $532.2 million of goodwill. In the second quarter of 2023, we determined the lower than 
previously projected actual and forecasted financial performance of our Semiconductor reporting unit to be a triggering event 
for an interim goodwill impairment test. We determined the fair value exceeded the carrying value as of June 30, 2023. Our 
Semiconductor reporting unit's value increased from our interim test as of June 30, 2023 due to further progression in our 
growth initiatives for the reporting unit. We considered the sensitivity of the valuation of our Semiconductor reporting unit to 
adverse changes in our projected cash flows under three separate alternative scenarios. First, with a 5% reduction in forecasted 
sales used in our valuation model, we estimate the fair value of the Semiconductor reporting unit would exceed its carrying 
value by approximately 12%. Second, with a 1% increase in the discount rate as of November 1, 2023 we estimate our fair 
value of the Semiconductor reporting unit would exceed its carrying value by approximately 9%. For the third scenario, the 
combination of a 1% increase in discount rate and 5% reduction in forecasted sales would result in the fair value of our 
Semiconductor reporting unit approximating the carrying value. All annual and interim impairment tests of goodwill for the 
Semiconductor reporting unit performed during the 3-years ended December 31, 2023 indicated there was no impairment of 
goodwill for the Semiconductor reporting unit.      

The fair value of the three reporting units of our Sealing Technologies segment all exceeded their respective carrying 

values by more than 75% as of November 1, 2023.  Our annual impairment test of the goodwill for the three reporting units of 
our Sealing Technologies segment as of November 1, 2022 and 2021 indicated no impairment.

Annual assessments are conducted in the context of information that was reasonably available to us as of the date of the 
assessment including our best estimates of future sales volumes and prices, material and labor cost and availability, operational 
efficiency including the impact of projected capital asset additions, and the discount rates and tax rates. 

Other intangible assets are recorded at cost or, when acquired as a part of a business combination, at estimated fair value. 
These assets include customer relationships, patents and other technology-related assets, trademarks, licenses, and non-compete 
agreements. Intangible assets that have definite lives are amortized using a method that reflects the pattern in which the 
economic benefits of the assets are consumed or the straight-line method over estimated useful lives of 1 to 21 years. Intangible 
assets with indefinite lives, which are primarily trade names, are subject to at least annual impairment testing, which were 
conducted as of November 1 in 2023, 2022, and 2021. The impairment testing compares the fair value of the intangible asset 
with its carrying amount using the relief from royalty method. The testing completed as of November 1, 2023, 2022 and 2021, 
indicated no impairment.  Interim tests may be required if an event occurs or circumstances change that would more likely than 
not reduce the fair value below the carrying value or change the useful life of the assets.   

Debt – Debt issuance costs associated with our senior secured revolving credit facility are presented as an asset and 
subsequently amortized into interest expense ratably over the term of the revolving debt arrangement. Debt issuance costs 
associated with any of our other debt instruments that are incremental third-party costs of issuing the debt are recognized as a 
reduction in the carrying value of the debt and amortized into interest expense over the time period to maturity using the interest 
method.  

Derivative Instruments – We use derivative financial instruments to manage our exposure to various risks. The use of 

these financial instruments modifies the exposure with the intent of reducing our risk. We do not use financial instruments for 
trading purposes, nor do we use leveraged financial instruments. The counterparties to these contractual arrangements are major 
financial institutions. We use multiple financial institutions for derivative contracts to minimize the concentration of credit risk. 
The current accounting rules require derivative instruments, excluding certain contracts that are issued and held by a reporting 
entity that are both indexed to its own stock and classified in shareholders’ equity, be reported in the Consolidated Balance 
Sheets at fair value and that changes in a derivative’s fair value be recognized currently in earnings unless specific hedge 
accounting criteria are met.

Fair Value Measurements – Fair value is defined as the exchange price that would be received for an asset or paid to 
transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction 
between market participants on the measurement date.

We utilize a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three 

broad levels. The following is a brief description of those three levels:

•

Level 1: Observable inputs such as quoted prices in active markets for identical assets or liabilities.

61

•

•

Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or
indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for
identical or similar assets or liabilities in markets that are not active.

Level 3: Unobservable inputs that reflect our own assumptions.

The fair value of intangible assets associated with acquisitions is determined using an income valuation approach. 
Projecting discounted future cash flows requires us to make significant estimates regarding projected revenues and profit 
margins, projected capital expenditures, changes in working capital, discount rates, attrition rates, royalty rates, obsolescence 
rates and tax rates. This non-recurring fair value measurement would be classified as Level 3 due to the absence of quoted 
market prices or observable inputs for assets of a similar nature.

We review the carrying amounts of long-lived assets when certain events or changes in circumstances indicate that the 

carrying amounts may not be recoverable.  An impairment loss is recognized when the carrying amount of the asset group is not 
recoverable and exceeds its fair value.  We estimate the fair values of assets subject to long-lived asset impairment based on our 
own judgments about the assumptions that market participants would use in pricing the assets.  In doing so, we use a market 
approach when available or an income approach based upon discounted cash flows.  The key assumptions used for the 
discounted cash flow approach include expected cash flows based on internal business plans, projected growth rates, discount 
rates, and royalty rates for certain intangible assets.  We classify these fair value measurements as Level 3.

Similarly, the fair value computations for the recurring impairment analyses of goodwill and indefinite-lived intangible 

assets would be classified as Level 3 due to the absence of quoted market prices or observable inputs. The key assumptions 
used for the discounted cash flow approach include projected revenues and profit margins, projected capital expenditures, 
changes in working capital, discount rates, tax rates and royalty rates for certain indefinite-lived intangible assets. Significant 
changes in any of those inputs could result in a significantly different fair value measurement.

Pension Benefits - Amortization of the net gain or loss resulting from experience different from that assumed and from 

changes in assumptions is included as a component of benefit cost.  If, as of the beginning of the year, that net gain or loss 
exceeds 10% of the greater of the projected benefit obligation or the market-related value of plan assets, the amortization is that 
excess divided by the average remaining service period of participating employees expected to receive benefits under the plan.  
We amortize prior service cost using the straight-line basis over the average future service life of active participants.

For segment reporting purposes, we allocate service cost to each location generating those costs.  All other components of 

net periodic pension cost are reported in other (non-operating) expense. 

Recently Issued Accounting Guidance

In November 2023, an accounting standards update was issued that improves reportable segment disclosures surrounding 
significant segment expenses. The amendments in this guidance are effective for financial statements issued for annual periods 
beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early 
adoption permitted. We are currently evaluating the new guidance. 

In December 2023, an accounting standards update was issued that will require changes in income tax disclosures. The 

standard is effective for financial statements issued for annual periods beginning after December 15, 2024, with early adoption 
permitted. The standard requires prospective adoption with the understanding that there will be a lack of comparability between 
reporting periods. Alternatively, retrospective adoption is also permitted. We are currently evaluating the new guidance and do 
not expect it to have a significant impact to our income tax disclosure.

2. Acquisitions

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 acquisition was paid for with $853.9 million in cash, net of cash acquired.  We funded the payment with available 
cash on hand, borrowings under our revolving credit facility and borrowings under new term loan facilities.  Additionally, there 
were $15.0 million of acquisition-related costs recorded during the year ended December 31, 2021, which were expensed when 

62

incurred and included in selling, general and administrative expense in the accompanying Consolidated Statement of Operations 
for the year then ended.

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

Alluxa works in collaboration with customers across major end markets to provide customized, complex precision coating 

solutions through its specialized technology platform and proprietary processes. Alluxa has cultivated long-standing customer 
relationships across its diversified customer base. Alluxa’s global distribution capabilities support the company’s international 
reach, serving customers across the Americas, Europe, and Asia. Founded in 2007, Alluxa has two locations in California and is 
headquartered in Santa Rosa, California.

In connection with the completion of the transaction, we entered into a limited liability operating agreement (the “Alluxa 

LLC Agreement”) with respect to the “Alluxa Acquisition Subsidiary” in connection with the rollover transaction with the 
Alluxa Executives receiving approximately 7% of the equity interests of the Alluxa Acquisition Subsidiary in return for their 
contribution of the rollover shares of Alluxa. Pursuant to the Alluxa LLC Agreement, each Alluxa Executive has the right to 
sell to us, and we have the right to purchase from each Alluxa Executive (collectively, the “Put and Call Rights”), one-third of 
the Alluxa Executive equity interests in the Alluxa Acquisition Subsidiary during each of three exercise periods in 2024, 2025 
and 2026, with any amount not sold or purchased in a prior exercise period being carried forward to the subsequent exercise 
periods (although for one Alluxa Executive who transitioned to a consulting role on January 1, 2023, the full amount of his 
equity interests are subject to the Company’s right to purchase on June 30, 2024, with two-thirds of the equity interests 
purchasable at the fixed value of the equity interests as set forth in the Alluxa LLC Agreement). The Alluxa LLC Agreement 
also provides for the purchase by us of all of an Alluxa Executive's equity interests in the Alluxa Acquisition Subsidiary in 
connection with the termination of employment of the Alluxa Executive under specified circumstances, with payments in 
certain circumstances to be made in annual installments. In certain cases involving the termination of an Alluxa Executive's 
employment, the consideration payable to an Alluxa Executive for the purchase of his equity interests is equal to the fixed value 
set forth in the Alluxa LLC Agreement (an aggregate of $17.85 million for all of the Alluxa Executives). In all other cases, 
including upon any exercise of the Alluxa Put and Call Rights, the consideration payable under the Alluxa LLC Agreement in 
connection with any such purchase by us of an Alluxa Executive's equity interests in the Alluxa Acquisition Subsidiary is equal 
to the greater of the fixed value of the equity interests as set forth in the Alluxa LLC Agreement or a price based upon a 
multiple of twelve-month adjusted EBITDA based upon certain financial metrics of the Alluxa Acquisition Subsidiary, plus 
cash and less indebtedness of the Alluxa Acquisition Subsidiary prior to the relevant payment, and subject to certain 
adjustments dependent upon the circumstances of the purchase and sale.  

On September 25, 2019, we acquired all of the equity securities of  LeanTeq Co., Ltd. and its affiliate LeanTeq LLC 

(collectively referred to as “LeanTeq”). LeanTeq primarily provides refurbishment services for critical components and 
assemblies used in state-of-the-art semiconductor equipment. This equipment is used to produce the latest and most 
technologically advanced microchips for smartphones, autonomous vehicles, high-speed wireless connectivity, artificial 
intelligence, and other leading-edge applications.  Founded in 2011 and headquartered in Taoyuan City, Taiwan, LeanTeq has 
two locations in Taiwan and one in the United States (Silicon Valley). LeanTeq is included within the Advanced Surface 
Technologies segment.

A limited liability company agreement (the "LeanTeq LLC Agreement") entered into with respect to Lunar as part of the 
LeanTeq acquisition, provided Enpro with the right to buy from each LeanTeq Executive (each a LeanTeq "Call Option”), and 
each LeanTeq Executive with the right to sell to Enpro (the "Put Option") such LeanTeq Executive's Rollover Equity as 
follows:

Enpro had the right to buy, and the LeanTeq Executive had the right to sell, such Rollover Equity within 90 days 

following the third anniversary of the closing and payable in two installments as follows (the "Put/Call Price"):

• Half of the price payable for the Rollover Equity is to be equal to a pro rata portion of a multiple of EBITDA (as 

defined) of Lunar (on a consolidated basis) during the last 12 months (“LTM”) ending on the closest month end prior 
to the last month end before the purchase or sale (the "First Measurement Date") less Lunar's consolidated net debt in 
excess of cash as of the First Measurement Date (the "First Exercise Price"). The applicable multiple depends on the 
future LTM EBITDA margin and revenue growth;

• The remaining half of the price payable for the Rollover Equity is to be equal to an amount that is the higher of the 
First Exercise Price and a pro rata portion of a multiple of EBITDA of Lunar (on a consolidated basis) during the 

63

LTM prior to the first anniversary of the First Measurement Date (the "Second Measurement Date") less Lunar's 
consolidated net debt in excess of cash as of the Second Measurement Date. The applicable multiple depends on the 
future LTM EBITDA margin and revenue growth.

• During the fourth quarter of 2022, Enpro acquired all the equity securities of Lunar owned by the LeanTeq

Executives and became the sole owner of LeanTeq. As a result of this purchase transaction, $35.0 million of our
Redeemable Non-Controlling Interests was reclassified as a liability. We entered into a subsequent agreement with
the LeanTeq Executives where we agreed to pay the full Put/Call Price calculated at the First Measurement Date and
paid $41.9 million in December 2022, which was the minimum purchase price for these equity securities, of which
$7.8 million eliminated our outstanding deferred compensation liability and $34.1 million reduced the liability
attributable to the redeemable non-controlling interest acquisition. We anticipate an additional $1.1 million payment
in the first quarter of 2024 based on Put/Call Price determined at the Second Measurement Date, which was subject to
the financial performance of LeanTeq through November 2023. We have recorded this anticipated $1.1 million
payment as a liability included in accrued expenses on our consolidated balance sheet as of December 31, 2023.

The fair value of the Alluxa Executives' equity interests and the LeanTeq Executives' Rollover Equity was estimated as of 
the closing date of those transactions.  Due to the presence of the put arrangements and thus that redemption is not solely within 
our control, the Alluxa Executives' equity interests are, and, prior to December 2022, the LeanTeq Executives' Rollover Equity 
had been, presented as redeemable non-controlling interests. We initially recognized the amount at fair value, inclusive of the 
put-call provisions. We adjust the redeemable non-controlling interests when the redemption value exceeds the carrying value 
with changes recognized as an adjustment to equity.

Sales of $8.6 million and a pre-tax loss of  $1.9 million for NxEdge are included in our Consolidated Statement of 
Operations for the year ended December 31, 2021.  The following unaudited pro forma condensed consolidated financial results 
of operations for the years ended December 31, 2022 and 2021 are presented as if these acquisitions had been completed before 
January 1, 2021:

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 January 1, 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 year ended December 31, 2021 was adjusted to exclude $15.0 million of pre-tax acquisition-related costs.  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 these 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 January 1, 2021, or of future 
results of the consolidated entities.

3. Other Income (Expense)

Operating

We incurred $5.0 million, $3.0 million and $2.5 million of restructuring and impairment costs, excluding goodwill

impairment, for the years ended December 31, 2023, 2022 and 2021, respectively. See Note 1, "Overview, Basis of 
Presentation, and Significant Accounting Policies" for information related to goodwill impairment charges incurred in 2023 and 
2022. 

Of the restructuring and impairment costs incurred in 2023 and 2022, we incurred $4.3 million and  $1.8 million, 

respectively, of restructuring costs related to the reorganization of sites and functions, primarily in the United States 
and$0.7 millionand $1.2 million, respectively, of non-cash impairment charges of long-lived assets. 

During 2021, we conducted a number of  restructuring activities throughout our operations which  mostly comprised of 

targeted workforce reductions. All costs associated with such initiatives were incurred in 2021.

Also included in other operating income (expense) for the years ended December 31, 2022 and 2021 were $0.1 million, 

and $(0.1) million of other costs, respectively.

Non-Operating

During 2023, 2022 and 2021, we recorded expense of $2.9 million, $5.1 million and $8.3 million, respectively, due to 

environmental reserve increases based on additional information at several specific sites and other ongoing obligations of 
previously owned businesses. Refer to Note 19, "Commitments and Contingencies - Environmental," for additional information 
about our environmental liabilities.

We report the service cost component of pension and other postretirement benefits expense in operating income in the 

same line item or items as other compensation costs arising from services rendered by the pertinent employees during the 
period. The other components of net benefit cost are presented in other income (expense). For the years ended December 31, 
2023, 2022, 2021, we reported approximately $1.5 million of expense and $3.6 million and $8.5 million, respectively, of  
income on the Consolidated Statements of Operations related to the components of net benefit cost other than service cost.  
Refer to Note 14, "Pension," for additional information regarding net benefit costs.

In connection with the sale of GGB, accounted for as a discontinued operation, in the fourth quarter of 2022, we issued a 
note between a domestic and foreign entity that was denominated in a foreign currency. As a result, we recorded a $3.8 million 
loss due to the change in exchange rate in December 2022. In January 2023, we hedged the outstanding notes to minimize 
future gains and losses. In 2023, we recorded a $2.2 million loss due to the change in exchange rate.

In 2022, we evaluated our outstanding long-term receivable related to anticipated receipts from legacy asbestos insurance 

claims and adjusted the receivable down by $2.8 million.

In connection with the acquisition of Aseptic in 2019, we recognized a liability for uncertain tax positions and a related 

indemnification asset for the portion of that liability recoverable from the seller. We determined the statute of limitations 
expired on some of the uncertain tax positions in 2022 and 2021 and, accordingly, removed a portion of the liability and 
receivable. For the year ended December 31, 2022 and 2021, the release of the related liability was recorded as part of our tax 
expense and we recorded a $0.9 million and $3.0 million expense, respectively, related to the reversal of the receivable in other 
non-operating income (expense) on our consolidated statement of operations. 

In 2021, we recorded a pre-tax gain of $17.5 million primarily related to the sale of our  polymer components business 
unit, which was principally located in Houston, Texas and included in our Sealing Technologies segment. Sales reported for 
this business included in our net sales for the year ended December 31, 2021 were $21.4 million. 

For a further discussion on businesses disposed of, see Note 20, "Discontinued Operations and Dispositions."

Additional costs included in other non-operating primarily are attributable to costs associated with previously divested 

businesses.

At December 31, 2023, we had $0.9 million of foreign net operating loss carryforwards, of which $0.4 million expire at 

various dates from 2038 through 2040 if unused, and $0.5 million have an indefinite carryforward period. We also have federal 
and state tax credit carryforwards of $3.4 million which expire at varying dates between 2027 and 2039 as well as state net 
operating loss carryforwards with a tax effect of $1.5 million which expire at various dates from 2024 through 2042. These net 
operating loss and tax credit carryforwards may be used to offset a portion of future tax liability and thereby reduce or eliminate 
our federal, state or foreign income taxes otherwise payable.

Because of the transition tax, GILTI, and Subpart F provisions, undistributed earnings of our foreign subsidiaries totaling 

$251.0 million at December 31, 2022 have been subjected to U.S. income tax or are eligible for the 100 percent dividends-
received deduction under Section 245A of the Internal Revenue Code ("IRC") provided in the Tax Cuts and Jobs Act. 
Additionally, undistributed earnings are estimated to be $179.5 million as of December 31, 2023. Whether through the 
application of the 100-percent dividends received deduction, or distribution of these previously-taxed earnings, we do not 
intend to distribute foreign earnings that will be subject to any significant incremental U.S. or foreign tax. During 2023, we 
repatriated $72.6 million of earnings from our foreign subsidiaries, resulting in only $0.4 million of withholding taxes net of 

67

refunds to be received. We have determined that estimating any tax liability on our investment in foreign subsidiaries is not 
practicable.  Therefore, we have not recorded any deferred tax liability on undistributed earnings of foreign subsidiaries. 

We determined, based on the available evidence, that it is uncertain whether certain entities in various jurisdictions will 
generate sufficient future taxable income to recognize certain of these deferred tax assets. As a result, valuation allowances of 
$2.7 million and $10.7 million have been recorded as of December 31, 2023 and 2022, respectively. Valuation allowances 
recorded relate to certain state and foreign net operating losses and other net deferred tax assets in jurisdictions where future 
taxable income is uncertain. In addition, $1.8 million and $2.0 million of the valuation allowance recorded as of December 31, 
2023 and 2022, respectively, relate to general foreign tax credit carryforwards, due to uncertainty around the ability to generate 
the requisite foreign source income to utilize that portion of the foreign tax credits. Valuation allowances may arise associated 
with deferred tax assets recorded in acquisition accounting.  In accordance with applicable accounting guidelines, any reversal 
of a valuation allowance that was recorded in acquisition accounting reduces income tax expense.

The effective income tax rate from continuing operations varied from the statutory federal income tax rate as follows:

Statutory federal income tax rate
U.S. taxation of foreign profits, net of foreign tax credits
Research and employment tax credits
State and local taxes
Foreign tax rate differences

The effective tax rate for 2023 was primarily driven impairment of non-deductible goodwill, the foreign rate differential 

related to certain foreign earnings that were subject to higher tax rates, and releasing valuation allowances on certain tax 
attributes. The effect of these items resulted in a net $21.6 million increase in income tax expense.

The GILTI provisions require us to include in our U.S. income tax returns certain current foreign subsidiary earnings net 
of foreign tax credits, subject to limitation. We elected to account for the GILTI tax in the period in which it is incurred. As a 
result of these provisions, our effective tax rate was increased by 4.4% due to GILTI.  

As of December 31, 2023 and 2022, we had $5.0 million and $4.5 million, respectively, of gross unrecognized tax 

benefits. Of the gross unrecognized tax benefit balances as of December 31, 2023 and 2022, $4.1 million and $4.1 million, 
respectively, would have an impact on our effective tax rate if ultimately recognized.

We record interest and penalties related to unrecognized tax benefits in income tax expense.  In addition to the gross 
unrecognized tax benefits above, we had $1.4 million and $1.2 million accrued for interest and penalties at December 31, 2023 
and 2022, respectively. Income tax expense includes $0.2 million,  $(0.2) million and $(1.7) million for the years ended 
December 31, 2023, 2022, and 2021, respectively, for interest and penalties related to unrecognized tax benefits.

U.S. federal income tax returns for tax years 2020 and forward remain open to examination.  We and our subsidiaries are 

also subject to income tax in multiple state, local and foreign jurisdictions. Substantially all significant state, local and foreign 
income tax returns for the years 2019 and forward are open to examination. Various state and foreign tax returns are currently 
under examination. We expect that some of these examinations may conclude within the next twelve months, however, the final 
outcomes are not yet determinable.  In addition, gross unrecognized tax benefits may be reduced by $2.8 million within the next 
twelve months as the applicable statute of limitation expire.

5. Earnings Per Share

Basic earnings per share is computed by dividing the income by the applicable weighted-average number of common
shares outstanding for the period. Diluted earnings per share is calculated using the weighted-average number of shares of 
common stock as adjusted for any potentially dilutive shares as of the balance sheet date. The computation of basic and diluted 
earnings per share for calendar years 2023, 2022, and 2021 is as follows (in millions, except per share data):

We regularly enter into operating leases primarily for real estate, equipment, and vehicles. Operating lease arrangements

are generally utilized to secure the use of assets if the terms and conditions of the lease or the nature of the asset makes the lease 
arrangement more favorable than a purchase. Leases with an initial term of 12 months or less are not recorded on the balance 
sheet. We have elected an accounting policy to combine lease and non-lease components. 

Our building leases have remaining terms up to ten years, some of which contain options to renew up to five years, and 

some of which contain options to terminate. Some leases contain non-lease components, which may include items such as 
building common area maintenance, building parking, or general service and maintenance provided for leased assets by the 
lessor. Our vehicle, equipment, and other leases have remaining lease terms up to five years, some of which contain options to 
renew or become evergreen leases, with automatic renewing one-month terms, and some of which have options to terminate. 

Our right of use assets and liabilities related to operating leases as of December 31, 2023 and December 31, 2022 are as

Approximately 96% of the dollar value of our operating lease assets and liabilities arise from real estate leases and 
approximately 4% arise from equipment and vehicle leases as of December 31, 2023. As of December 31, 2022, approximately 
98% of the dollar value of our operating lease assets and liabilities arise from real estate leases and approximately 2% arise 
from equipment and vehicle leases.

We entered into additional operating leases, including leases acquired through business acquisitions, and renewed 
existing leases that resulted in new right-of-use assets totaling $12.3 million, $5.7 million, and $30.0 million for the years ended 
December 31, 2023, December 31, 2022, and December 31, 2021, respectively. 

Most of our leases do not provide an implicit rate for calculating the right of use assets and corresponding lease 
liabilities. Accordingly, we determine the interest rate that we would have to pay to borrow on a collateralized basis over a 
similar term and amount equal to the lease payments in similar economic environments. 

Our lease costs and cash flows for the years ended December 31, 2023 and December 31, 2022 were as follows:

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 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.

Borrowings under the 364-Day Facility bore interest at an annual rate of LIBOR plus 1.50% or base rate plus 0.50%.  

Initially, borrowings under the Facilities (other than the 364-Day Facility) bore interest at an annual rate of LIBOR plus 1.75% 
or base rate plus 0.75%, although these interest rates were subject to incremental increase or decrease based on a consolidated 
total net leverage ratio.  On November 8, 2022, we entered into a First Amendment to the Amended Credit Agreement, which 

73

replaced the LIBOR-based interest rate option with an option based on Term SOFR ("Secured Overnight Financing Rate")  plus 
(i) a credit spread adjustment of 0.10% and (ii) 1.75%, again subject to incremental increase or decrease based on a
consolidated total net leverage ratio.  In addition, a commitment fee accrues with respect to the unused amount of the Revolving
Credit Facility at an annual rate of 0.225%, which rate is also subject to incremental increase or decrease based on a
consolidated total net leverage ratio.

The Term Loan A-1 Facility amortized 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 amortizes 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 did not amortize and was 
repaid in full in the quarter ended September 30, 2022. 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 December 31, 2023.

On July 21, 2023, we entered into a waiver agreement under the Amended Credit Agreement that waived the requirement 

to prepay the Facilities with remaining excess net cash proceeds related to the sale of GGB and GPT that had not been 
reinvested in operating assets within 365 days from the date of the sale.  In conjunction with this waiver, on July 26, 2023, 
EnPro voluntarily prepaid all outstanding borrowings and accrued and unpaid interest under the Term Loan A-1 Facility (a 
remaining principal balance of $133.1 million and accrued interest of $0.6 million). 

The indenture governing the Senior Notes requires us to offer to repurchase the Senior Notes at a price equal to 100.0% of 

the principal amount thereof plus accrued and unpaid interest, in the event that the net cash proceeds of certain asset sales are 
not reinvested in acquisitions, capital expenditures, or used to repay or otherwise reduce specified indebtedness within a 
specified period, to the extent the remaining net proceeds exceed a specified amount.  After taking into account the repayment 
of borrowings under the Term Loan A-1 Facility noted above, forecasted capital expenditures, and other applicable 
expenditures, we expect to meet all reinvestment requirements under the indenture related to the excess net cash proceeds from 
the sales of GGB and GPT.

The borrowing availability under our Revolving Credit Facility at December 31, 2023 was $390.0 million after giving 
consideration to $10.0 million of outstanding letters of credit. The balance of borrowings outstanding under the Term Loan A-2 
Facility at December 31, 2023 was $299.3 million. 

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"). 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. 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.

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 offer to repurchase 

74

the Senior Notes at a price equal to 100.0% of the principal amount thereof plus accrued and unpaid interest, in the event that 
the net cash proceeds of certain asset sales are not reinvested in acquisitions, capital expenditures, or used to repay or otherwise 
reduce specified indebtedness within a specified period, to the extent the remaining net proceeds exceed a specified amount. 

We were in compliance with all of the covenants under the indenture governing the Senior Notes as of December 31, 

2023.

The payments for long-term debt shown in the table above reflect the contractual principal amount for the Senior Notes 

and Term Loan A-2 Facility. In the Consolidated Balance Sheet as of December 31, 2023, these amounts are shown net of 
unamortized debt discounts aggregating $3.3 million pursuant to applicable accounting rules.

Debt Issuance Costs

During 2021, we capitalized $4.7 million of debt issuance costs in connection with the Amended Credit Agreement. At 

December 31, 2023, the remaining unamortized balance of these costs was $2.3 million.

12. Derivatives and Hedging

We are exposed to foreign currency risks that arise from normal business operations. These risks include the translation

of local currency balances on our foreign subsidiaries’ balance sheets, intercompany loans with foreign subsidiaries and 
transactions denominated in foreign currencies. We strive to control our exposure to these risks through our normal operating 
activities and, where appropriate, through derivative instruments. We periodically enter into contracts to hedge forecasted 
transactions that are denominated in foreign currencies. Since December 2022, we have entered into monthly forward contracts 
to hedge a 95 million Euro exposure on an intercompany note agreement related to proceeds from the GGB sale allocated to 
foreign subsidiaries. We expect this position to be resolved in 2024. The notional amount of foreign exchange contracts was 
$110.5 million and $103.3 million at December 31, 2023 and 2022, respectively.  All foreign exchange contracts outstanding at 
December 31, 2023 expired in January of 2024.

The foreign exchange contracts were recorded at their fair market value as of December 31, 2023 with changes in market 

value recorded in income. The earnings impact of any foreign exchange contract that is specifically related to the purchase of 
inventory is recorded in cost of sales and the changes in market value of all other contracts are recorded in selling, general and 
administrative expense in the Consolidated Statements of Operations with the exception of our monthly forward contracts to 
hedge our Euro exposure which are recorded in other expense. The balances of foreign exchange derivative assets are recorded 
in other current assets and the balances of foreign exchange derivative liabilities are recorded in accrued expenses in the 
Consolidated Balance Sheets.

In September 2018, we entered into cross currency swap agreements (the "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 then 
outstanding fixed-rate 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 matured on September 15, 2022. At settlement, we received $30.8 million in cash, of which $27.4 million 

represented the fair value of the contracts as of the settlement date and $3.4 million represented interest receivable. Realized 
gains totaling $20.8 million, net of tax, as of the maturity date are included in accumulated other comprehensive income.

75

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 the 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 Additional Swap agreement, 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 Additional 
Swap. There was no principal exchange at the inception of the arrangement, and there will be no exchange at maturity. At 
maturity (or earlier at our option), we and the counterparty will settle the Additional Swap agreement at its 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 Additional Swap agreement was entered into.

We have designated the Additional Swap as a qualifying hedging instrument and are accounting for it as a net investment 

hedge. At December 31, 2023, the fair value of  the Additional Swap equaled $3.1 million and was recorded within our other 
(non-current) assets on the Consolidated Balance Sheet. The gains and losses resulting from fair value adjustment to the 
Additional Swap agreement, excluding interest accruals related to the above receipts, are recorded in accumulated other 
comprehensive income within our cumulative foreign currency translation adjustment, as the Additional Swap is effective in 
hedging the designated risk. Cash flows related to the Additional Swap are included in operating activities in the Consolidated 
Statements of Cash Flows, aside from the ultimate settlement at maturity with the counterparty, which will be included in 
investing activities.

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 approximate 

their respective fair values, except for the following:

a Level 2 computation because the market is not active. 

14. Pension

We have non-contributory defined benefit pension plans covering eligible employees in the United States, Mexico,
Taiwan and several European countries. Salaried employees’ benefit payments are generally determined using a formula that is 
based on an employee’s compensation and length of service. We closed our defined benefit pension plan for new salaried 

76

employees in the United States who joined the Company after January 1, 2006, and, effective January 1, 2007, benefits were 
frozen for all salaried employees who were not age 40 or older as of December 31, 2006 and benefits for all remaining eligible 
salaried employees were frozen as of January 1, 2021.  Benefits for hourly employees in the United States were frozen as of 
January 1, 2024. 

Certain of our employees also participate in voluntary contributory retirement savings plans for salaried and hourly 

employees maintained by us. Under these plans, eligible employees can receive matching contributions up to the first 6% of 
their eligible earnings. Certain employees hired prior to August 1st, 2016 are eligible to receive an additional 2% company 
contribution each year. We recorded $9.5 million, $8.6 million and $8.3 million in expenses in 2023, 2022 and 2021, 
respectively, for matching contributions under these plans.

Our general funding policy for qualified defined benefit pension plans historically has been to contribute amounts that are 

at least sufficient to satisfy regulatory funding standards. In 2023, we contributed $5.5 million, in cash, to our U.S. pension 
plans. No contributions were made in 2022 or 2021. The contribution was made in 2023 in order to meet a funding level 
sufficient to avoid variable fees from the PBGC on the underfunded portion of our pension liability. We do not anticipate 
making contributions in 2024 to our U.S. defined benefit pension plans and we expect to make total contributions of 
approximately $1.0 million in 2024 to the foreign pension plans. 

The projected benefit obligation and fair value of plan assets for the defined benefit pension plans with projected benefit 

obligations in excess of plan assets were $7.7 million and $0.2 million at December 31, 2023, and $6.1 million and $0.2 million 
at December 31, 2022, respectively.  The accumulated benefit obligation and fair value of plan assets for the defined benefit 
pension plans with accumulated benefit obligations in excess of plan assets were $5.3 million and $0.2 million at December 31, 
2023, and $4.3 million and $0.2 million at December 31, 2022, respectively.

The following table sets forth the changes in projected benefit obligations and plan assets of our defined benefit pension 

and other non-qualified and postretirement plans as of and for the years ended December 31, 2023 and 2022.

The discount rate reflects the current rate at which the pension liabilities could be effectively settled at the end of the year. 

The discount rate was determined with a model that uses a theoretical portfolio of high quality corporate bonds specifically 
selected to produce cash flows closely related to how we would settle our retirement obligations. This produced a discount rate 
of 5.1% at December 31, 2023.  As of the date of these financial statements, there are no known or anticipated changes in our 
discount rate assumption that will impact our pension expense in 2024.  A 25 basis point decrease in our discount rate, holding 
constant our expected long-term return on plan assets and other assumptions, would increase pension expense by approximately 
$0.2 million per year.

The overall expected long-term rate of return on assets was determined based upon weighted-average historical returns 

over an extended period of time for the asset classes in which the plans invest according to our current investment policy.

We use the Pri-2012 base mortality table with the MP-2021 projection scale to value our domestic pension liabilities.

Plan Assets

The asset allocation for pension plans at the end of 2023 and 2022, and the targeted allocation for 2024, by asset category 

are as follows:

Our investment goal is to maximize the return on assets, over the long term, by investing in equities and fixed income 
investments while diversifying investments within each asset class to reduce the impact of losses in individual securities. Equity 
investments include a mix of U.S. large capitalization equities, U.S. small capitalization equities and non-U.S. equities. Fixed 
income investments include a mix of treasury obligations and high-quality corporate bonds. The asset allocation policy is 
reviewed and any significant variation from the target asset allocation mix is rebalanced periodically. The plans have no direct 
investments in Enpro common stock.

The plans invest exclusively in mutual funds whose holdings are marketable securities traded on recognized markets and, 
as a result, would be considered Level 1 assets. The investment portfolios of the various funds at December 31, 2023 and 2022 
are summarized as follows:

Mutual funds –  U.S. equity

Mutual funds – international equity

Mutual funds - fixed income treasury and corporate bonds

Other Post-Employment Retirement Benefits

We have liabilities related to other post-employment retirement benefits that were offered to certain employees of several 
legacy businesses owned by Enpro's predecessor as well as certain continuing operations. New employees are not offered these 
benefits and nearly all employees who were offered these benefits are retired. Disclosures related to these benefits are not 
included in the discussion and tables above. At December 31, 2023, we had $5.5 million of liabilities related to these benefits of 
which $1.8 million is a current liability. 

15. Shareholders' Equity

We have a policy under which we intend to declare regular quarterly cash dividends on our common stock, as
determined by our board of directors, after taking into account our cash flows, earnings, financial position and other relevant 
matters.  In accordance with this policy, total dividend payments of $24.3 million, $23.4 million, and $22.4 million were made 
during the years ended December 31, 2023, 2022, and 2021, respectively. 

On February 15, 2024 we announced that our board of directors had increased the quarterly dividend to $0.30 per share, 

commencing with the dividend to be paid on March 20, 2024 to all shareholders of record as of March 6, 2024.

In October 2022, our board of directors renewed their authorization for a new two-year program of up to $50.0 million 

for the repurchase of our outstanding common shares. We have not made any repurchases for the 3-year period ended 
December 31, 2023.

The shares for all repurchase plans are retired upon purchase.

17. Equity Compensation Plans

We have equity compensation plans (the “Plans”) that provide for the delivery of shares pursuant to various market and
performance-based incentive awards. As of December 31, 2023, there are 1.3 million shares available for future awards. Our 
policy is to issue new shares to satisfy share delivery obligations for awards made under the Plans.

The Plans permit awards of restricted share units to be granted to executives and other key employees. Generally, share 

units awarded vest in equal annual increments over three years. Compensation expense related to the restricted share units is 
based upon the market price of the underlying common stock as of the date of the grant and is amortized over the applicable 
vesting period using the straight-line method. As of December 31, 2023, there was $5.5 million of unrecognized compensation 
cost related to restricted share units expected to be recognized over a weighted-average remaining amortization period of 1.7 
years.

Under the terms of the Plans, performance share awards were granted to executives and other key employees during 

2023, 2022 and 2021. Each grant will vest if Enpro achieves specific financial objectives at the end of each three-year 
performance period. Additional amounts under these awards are paid out if objectives are exceeded, but some or all the awards 
may be forfeited if objectives are not met. 

Performance shares earned at the end of a performance period, if any, for shares issued in 2023 will be paid in actual 
shares of our common stock, less the number of shares equal in value to applicable withholding taxes if the employee chooses. 
Performance shares earned at the end of a performance period for awards granted in 2022, if any, and 2021 will be paid in cash, 
less applicable withholding taxes if the employee chooses. Awards are forfeited if a grantee terminates employment, during the 
performance period, except in the case of retirement. 

Compensation expense related to performance share awards payable in stock granted in 2023 is computed using the fair 
value of the awards at the date of grant. Potential shares to be issued for performance share awards granted in 2023 are subject 
to a market condition based on the performance of our stock, measured based upon a calculation of total shareholder return, 
compared to a group of peer companies. The fair value of these awards was determined using a Monte Carlo simulation 
methodology. Compensation expense for these awards was computed based upon this grant date fair value using the straight-
line method over the applicable performance period. 

82

Compensation expense related to the performance share awards payable in cash granted in 2022 and 2021 is computed 

using the fair value of the awards as of December 31, 2023. The fair value of these awards was determined using a Monte Carlo 
simulation methodology.  Compensation issued for performance share awards is subject to a market conditions based on the 
performance of our stock, measured based upon a calculation of total shareholder return, compared to a group of peer 
companies. Compensation expense for these awards is computed based upon the calculated fair value at the end of the period 
using the straight-line method over the applicable performance period. The shares will be remeasured and compensation 
expense will be adjusted based on the current market-based estimate. 

The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market 

condition stipulated in the award and calculates the fair value of each award. We issued performance share awards to eligible 
participants on February 16, 2023, February 15, 2022 and February 16, 2021.  We used the following assumptions in 
determining the fair value of these awards:

S&P 600 Capital Goods Index
Shares granted February 15, 2022

Enpro Inc.

The expected volatility assumption for us and each member of the peer group is based on each entity’s historical stock 

price volatility over a period equal to the length from the valuation date to the end of the performance cycle.  The annual 
expected dividend yield is based on annual expected dividend payments and the stock price on the date of grant.  The risk free 
rate equals the yield, as of the valuation date, on zero-coupon U.S. Treasury STRIPS that have a remaining term equal to the 
length of the remaining performance cycle.  

As of December 31, 2023 there was $2.1 million of unrecognized compensation cost related to nonvested performance 
share awards to be paid in cash and $2.9 million of unrecognized compensation cost related to nonvested performance share 
awards to be settled in shares of common stock. These costs are expected to be recognized over a weighted-average vesting 
period of 1.6 years.

The maximum potential number of shares to be issued at December 31, 2023 is represented by the restricted share units 

nonvested balance at December 31, 2023. The number of nonvested performance share awards shown in the table above 

83

 
represents the maximum potential shares to be issued. We account for forfeitures when they occur as opposed to estimating the 
number of awards that are expected to vest as of the grant date. 

During the first quarter of calendar 2021 and 2022, the Company granted Performance Shares to certain key employees 

which are payable in cash after a three-year vesting period. Actual payments to be made to participating employees are based on 
an initial target amount, which is adjusted based on the relative three-year performance of Enpro’s share price versus a set of 
peer companies. Expense related to each grant is recognized on a straight-line basis utilizing the best current estimate of the 
grant value at maturity. Expense recognized for calendar 2023, 2022 and 2021 was $9.1 million, $7.8 million, and $6.9 million, 
respectively. The total liability related to this Performance Share cash plan was $18.0 million at December 31, 2023, of which 
$12.4 million is classified as current.     

Non-qualified and incentive stock options were granted in 2021, 2022, and 2023. No stock option has a term exceeding 
10 years from the date of grant. All stock options were granted at not less than 100% of fair market value (as defined) on the 
date of grant.  As of December 31, 2023, there was $2.7 million of unrecognized compensation cost related to stock options.

We determine the fair value of stock options using the Black-Scholes option pricing formula. Key inputs into this formula 

include expected term, expected volatility, expected dividend yield, and the risk-free interest rate. We use the closing stock 
price on the grant date for determining the fair value. This fair value is amortized on a straight line basis over the vesting period. 
All options issued vest in equal annual increments over three years with the exception of options granted on November 26, 
2021 that vest equally at the end of one quarter years, one and one quarter years, and two and one quarter years. 

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 dividend assumption is based on our current expectations for our dividend policy. 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. When estimating forfeitures, we consider voluntary termination behaviors as 
well as analysis of actual option forfeitures.

Each non-employee director received an annual grant of common stock (or, at the directors' election, phantom shares) 

equal in value to $110,000 in the years ended December 31, 2023, 2022 and 2021. With respect to certain phantom shares 
awarded in prior years, we will pay each non-employee director in cash the fair market value of the director's phantom shares 
upon termination of service as a member of the board of directors.  The remaining phantom shares granted will be paid out in 
the form of one share of our common stock for each phantom share, with the value of any fractional phantom shares paid in 
cash.  Expense recognized in the years ended December 31, 2023, 2022 and 2021 related to these share and phantom share 
grants was $1.2 million, $1.0 million and $1.0 million, respectively.  No cash payments were used to settle phantom shares in 
2023, 2022 or 2021.

18. Business Segment Information

We aggregate our operating businesses into two reportable segments, Sealing Technologies and Advanced Surface
Technologies. Factors considered in determining our reportable segments include the economic similarity of the businesses, the 
nature of products sold, or solutions provided, the production processes and the types of customers and distribution methods.  

Our Sealing Technologies segment engineers and manufactures value-added products and solutions that safeguard a 

variety of critical environments, including:  metallic, non-metallic and composite material gaskets; dynamic seals; compression 
packing; elastomeric components; custom-engineered mechanical seals used in diverse applications; hydraulic components; 
test, measurement and sensing applications; sanitary gaskets; hoses and fittings for hygienic process industries; fluid transfer 
products for the pharmaceutical and biopharmaceutical industries; and commercial vehicle solutions used in wheel-end and 
suspension components that customers rely upon to ensure safety on our roadways. 

These products are used in a variety of markets, including chemical and petrochemical processing, nuclear energy, 

hydrogen, natural gas, food and biopharmaceutical processing, primary metal manufacturing, mining, water and waste 
treatment, commercial vehicle, aerospace (including commercial space), medical, filtration and semiconductor fabrication.  In 
all these industries, the performance and durability of our proprietary products and solutions are vital for the safety and 
environmental protection of our customers’ processes.  Many of our products and solutions are used in highly demanding 
applications, often in harsh environments, where the cost of failure is extremely high relative to the cost of our offerings to our 
customers. These environments include those where extreme temperatures, extreme pressures, corrosive agents, strict 
tolerances, or worn equipment create challenges for product performance.  Sealing Technologies offers customers widely 
recognized applied engineering, innovation, process know- how and enduring reliability, driving a lasting aftermarket for many 
of our products and solutions.   

Our Advanced Surface Technologies (AST) segment applies proprietary technologies, processes, and capabilities to 

deliver a highly differentiated suite of products and solutions for challenging applications in high-growth markets.  The 
segment’s products and solutions are used in demanding environments requiring performance, precision and repeatability, with 
a low tolerance for failure.  AST’s products and solutions include:  (i) cleaning, coating, testing, refurbishment and verification 
for critical components and assemblies used in semiconductor manufacturing equipment, with meaningful exposures to state-of-
the-art advanced node chip applications; (ii)  designing, manufacturing and selling specialized optical filters and proprietary 
thin-film coatings for the most challenging applications in the industrial technology, life sciences, and semiconductor markets; 
(iii) engineering and manufacturing complex front-end wafer processing sub-systems and new and refurbished electrostatic
chuck pedestals for the semiconductor equipment industry; and (iv) engineering and manufacturing edge-welded metal bellows
for the semiconductor equipment industry and critical applications in the space, aerospace and defense markets.  In many
instances, AST capabilities drive products and solutions that enable the performance of our customers’ high-value processes
through an entire life cycle.

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 

86

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 was recorded in selling, general, and administrative expenses on our Consolidated 
Statements of Operations and is directly related to the terms of the acquisitions. In the fourth quarter of 2022, Enpro acquired 
all of the LeanTeq non-controlling interests.

19. 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 investigation and remediation activities at 19 sites. At 14 of these sites, the 
future cost per site for us or our subsidiaries is expected to exceed $100,000. We do not conduct manufacturing operations at 
any of these sites. At all 19 sites, one or more of our subsidiaries formerly conducted business operations but no longer do. 
Among these 19 sites, investigations have been completed for 15 sites and are in progress at 4 sites. Among the 15 sites where 
investigations have been completed, 7 sites have remediation systems that are operating and our only obligation at the other 8 
sites is to conduct periodic monitoring. In addition to the 19 sites referenced above, the United States Environmental Protection 
Agency (the "EPA") has provided us notice that Enpro has potential responsibility at 1 additional site where one of our 
subsidiaries formerly conducted business operations but no longer does. We have responded to the EPA that we do not have 
responsibility at that site and are awaiting EPA's response.  

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 December 31, 2023 and 2022, we had 
recorded liabilities aggregating $39.0 million and $42.1 million, respectively, for estimated future expenditures relating to 
environmental contingencies. The current portion of our aggregate environmental liability included in accrued liabilities at 
December 31, 2023, was $8.2 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 

90

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 Holdings. In 
September 2022, EnPro Holdings paid $5.9 million as part of a settlement between those parties and EPA.  The payment will be 
held in escrow until court approval of the settlement. Our reserve for this site at December 31, 2023 was $0.7 million. Further 
adjustments to our reserve for this site are possible as new or additional information becomes available. 

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.

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. We entered 
into a First Modification of Original Administrative Settlement Agreement and Order on Consent effective July 8, 2022 for the 
performance of Engineering Evaluations and Cost Analyses of potential remedial options at each of the sites. 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 December 31, 
2023 for this site was $11.5 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 

91

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 
$2.9 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 December 31, 2023.

In addition to the two sites discussed above, we have additional reserves of $26.9 million, of which $13.5 million pertains 

to implementing and managing a solution to clean trichloroethylene soil and groundwater contamination at the location of a 
former operation in Water Valley, Mississippi. These amounts represent a reasonable estimate of our probable future costs to 
remediate these sites given the facts and circumstances known at December 31, 2023. 

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.

Changes in the carrying amount of the product warranty liability for the years ended December 31, 2023, 2022 and 2021

20. Discontinued Operation and Dispositions

In the third quarter of 2022, we entered into an agreement to sell our GGB business and announced our intention to sell

Garlock Pipeline Technologies, Inc. ("GPT").  These businesses, along with Compressor Products International ("CPI"), which 
was divested on December 21, 2021, comprised our entire Engineered Materials segment ("Engineered Materials"). As a result 
of classifying the GGB and GPT businesses as held for sale in the third quarter of 2022, we determined Engineered Materials to 
be discontinued operations. Accordingly, we have reported, for all periods presented, the financial condition, results of 
operations, and cash flows of Engineered Materials as discontinued operations in the accompanying financial statements.

On January 30, 2023 we completed the sale of GPT. In 2023, we received $28.9 million, net of transaction fees and cash 

sold, resulting in a pretax gain of $14.6 million recognized in the first quarter of 2023.

The sale of GGB closed on November 4, 2022 to The Timken Company. We received $298.2 million, net of transaction 

fees and cash sold, including $3.1 million of payments made in the first quarter of 2023. We recorded a pre-tax gain of  
$189.1 million as part of our discontinued operations in the fourth quarter of 2022. The sale of  GGB included a subsidiary of 
our Sealing Technologies segment which is not part of the discontinued operations described above. We recorded a pre-tax loss 

92

of $0.4 million related to the sale of this subsidiary. The loss on sale as well as operating activity of this subsidiary are included 
in continuing operations up to the date of the sale. 

On December 21, 2021, we completed the sale of specified equity interests and assets of CPI, which had been included in 
our Engineered Materials segment. We received $185.7 million, net of transaction fees and cash sold, resulting in a pre-tax gain 
of $117.6 million as part of our discontinued operations. 

Dispositions

On September 2, 2021, we sold certain assets and liabilities of our polymer components business unit, which was 
principally located in Houston, Texas and had been included in our Sealing Technologies segment. As a result of the sale, we 
recorded a pre-tax gain of $19.5 million in other income (expense) on our Consolidated Statement of Operations.

The results of our discontinued operations were as follows:

Net sales

Cost of sales

Gross profit

Operating expenses:

Selling, general, and administrative expenses

Total operating expenses

Operating income from discontinued operations

Income from discontinued operations before income taxes

Pursuant to applicable accounting guidance for the reporting of discontinued operations, allocations to our Engineered 

Materials segment for corporate services not expected to continue at the divested business subsequent to closing have not been 
reflected in the above financial statements of discontinued operations and have been reclassified to income from continuing 
operations in our accompanying consolidated financial statements for all periods. In addition, divestiture-related costs 
previously not allocated to our Engineered Materials segment that were incurred as a result of the divestiture of Engineered 
Materials have been reflected in the financial results of discontinued operations. As a result, income from discontinued 
operations before income taxes of Engineered Materials has been decreased by $1.7 million for the year ended December 31, 
2022 and increased $2.4 million, for the year ended December 31, 2021 with offsetting changes in corporate expenses of 
continuing operations.

Subsequent Events

On December 28, 2023, EnPro Holdings entered into an agreement to acquire Advanced Micro Instruments, Inc. (“AMI”)

for $210 million in cash, subject to customary purchase price adjustments related to the final acquisition date net working 
capital determination. We estimate that approximately 3% of the total consideration given for the acquisition of AMI is related 
to net tangible assets, excluding cash.

 AMI is a leading provider of highly-engineered, application-specific analyzers and sensing technologies that monitor 

critical parameters to maintain infrastructure integrity, enable process efficiency, enhance safety, and facilitate the clean energy 
transition. The acquisition closed on January 29, 2024 and thus the assets and operating results of AMI are not included in our 
2023 financial statements. AMI will be included as part of our Sealing Technologies segment.

Based in Costa Mesa, California, AMI serves customers in the midstream natural gas, biogas, industrial processing, 

cryogenics, food processing, laboratory, wastewater and aerospace markets. The company offers a portfolio of oxygen, 
hydrogen sulfide and moisture analyzers and proprietary sensing capabilities that detect contaminants in a variety of processes, 
including natural gas and biogas streams, which enable operators to avoid flaring and, thereby, reduce CO2 emissions. 

On February 21, 2024, we acquired all outstanding equity interests of the Alluxa Acquisition Subsidiary for $17.9 million 

and became the sole owner of the Alluxa. For an additional discussion on the equity interests of the Alluxa Acquisition 
Subsidiary, see Note 2, "Acquisitions".
