Key competitors for the Power Systems segment include MTU, Caterpillar Inc. and Wartsila Corporation.

Competitive Strengths

We believe the following strengths provide us with significant competitive advantages as we execute our business strategy:

Our Brands Set Industry Standards and Drive a Portfolio of Highly Repeatable, Stable Businesses

Our leading brands, including Garlock^®, STEMCO^®, GGB^® and Fairbanks Morse^®, have legacies ranging from 60 to over 125 years. We believe that the products sold under these leading brands are well established and highly recognized in their respective markets, and, in our flagship product lines, we hold leading market positions. In many cases, we expect our products are the products of choice for our customers given our long-standing histories of reliable performance in demanding and critical applications. We believe many of our products set industry standards around safety, emissions control, reliability, and performance. And we were among the first to market with a number of products, including opposed piston engines, non-asbestos sealing products, high-performance PTFE gaskets, metal-polymer bearings, and zero-PFOA (perfluorooctanoic acid) bearings. A meaningful percentage of our sales is generated by products that are either sole-sourced or customer-specified. The focus of our brand and business model has been, and continues to be, developing premium quality products that meet demanding performance standards, providing customers with focused service and support, and developing and nurturing enduring customer relationships.

Many of Our Products Perform in Demanding Environments and Serve Critical Applications

Many of our products support critical applications in demanding environments such as those characterized by high pressure, high temperature, chemical corrosion and requirement for zero failure. Notable examples include sealing products for nuclear reactor pressure vessels; seals, bearings and related products for

aircraft engines and landing gear; seals and related products used in the pharmaceutical industry; wheel-end and brake products for Class 8 trucks; and engines that provide propulsion or auxiliary power for U.S. Navy vessels. We believe many of our products’ long-standing histories of performance reliability in demanding environments and for critical applications provide significant commercial advantages, leading to value-based pricing opportunities that drive premium margins and capital returns. In addition, some applications in which our products serve are characterized by high customer switching costs, due to both the critical nature of the application and the specification process.

Our Highly Diversified Business Portfolio Leads to Stable Cash Flows

Our sales are generated across a broad range of industries and geographies. We serve more than 30 end markets, and approximately 43% of our 2017 net sales were from sales to customers outside of the United States. A slowdown in a specific industry or economy can be offset by an uptick in other markets, providing confidence in our ability to sustain profitability and stable cash flows over time. We also have a strong mix of aftermarket and OEM customers, with a roughly even split between these types of customers. Much of our OEM business is platform-based and sole-sourced, resulting in very low product displacement. Additionally, our large installed base of products generates a steady recurring aftermarket revenue stream.

We Have Positioned Our Company for Growth and Continuous Improvement

Since our spin-off from Goodrich Corporation (“Goodrich”) in 2002, we have systematically refined our business mix and model, and we are well positioned for future growth and continuous operational improvement. Initiatives undertaken include the following:

The EnPro Senior Executive Team is Composed of Members with Diverse Educational and Functional Backgrounds and Demonstrated Track Records of Success

Our executive management team is led by Steve Macadam, President and Chief Executive Officer, who has served in this capacity for the past ten years. Prior to joining EnPro, Mr. Macadam was CEO of two other industrial companies and a senior operating executive at a third manufacturer, all following an earlier career as Principal with McKinsey & Company. Others on the EnPro senior team bring a diverse mix of educational and functional backgrounds and demonstrated records of success at both EnPro and in their roles prior to joining EnPro. The varied backgrounds include experience with other industrial businesses and with professional consulting and accounting firms such as McKinsey and Ernst & Young. Marvin Riley, Executive Vice President and Chief Operation Officer, previously served as President of Fairbanks Morse (the Power Systems segment) and held a senior manufacturing position prior to that. Susan Sweeney, President of GGB, and Deepak Navnith, President of Fairbanks Morse, similarly held senior manufacturing positions prior to their current roles. Eric Vaillancourt, President of Stemco, Bill Favenesi, President of CPI, Gilles Hudon, President of Technetics and Mike Faulkner, President of Garlock all have strong commercial backgrounds.

Business Strategy

We seek to take advantage of our competitive strengths to execute our growth and cost reduction strategies and, as a result, to maximize our free cash flow. Examples include:

Capitalize on Secular Growth Trends in Core Lines of Business

We serve a diverse group of markets and geographies and seek to invest in, and capture the benefits of, positive secular trends.

In our Sealing Products segment, our Garlock business has benefitted from recent growth in the hydrocarbon processing, metals and mining and general industrial markets, and we expect these core markets to continue to experience favorable conditions in the near to mid-term. In addition, our Garlock business is expanding its presence in less cyclical and higher growth end markets such as food and pharmaceutical. At Technetics Group, we have been benefitting from strength in the semiconductor and aerospace markets. We are also investing in innovation and new product development and expect those investments to enhance our financial performance and competitive position. In response to significant declines and structural changes in the industrial gas turbine market, we are exiting that market to focus on our core strengths in high performance sealing and highly engineered components for the aerospace and semiconductor markets. In our Stemco business, which serves the heavy-duty trucking industry, we are benefitting from robust new truck and trailer builds, a strong aftermarket presence and from increasing penetration of the suspension segment of the market. Stemco is also capitalizing on its products that enhance highway safety and on regulatory trends addressing stopping distance, brake quality and fuel efficiency.

In our Engineered Products segment, our GGB business has benefitted recently from growth in the general industrial market and continued strength in the automotive markets, particularly in Europe where we have a strong automotive presence. GGB will continue to pursue incremental growth through efforts to convert legacy roller bearing applications in the U.S. to high performing and less costly plain bearings. We also seek to gain share in China as premium quality auto production develops to serve a rising middle class. At CPI, we have benefitted from the recovery in the oil and gas markets and favorable conditions in the petrochemical industry. We also recently introduced a new compressor lubrication monitoring product line that has received positive feedback from customers.

In our Power Systems segment, Fairbanks Morse is a significant supplier to the U.S. Navy and has a leading market share in the U.S. nuclear market. Future growth is anticipated to come primarily from U.S. Navy

ship building and fleet refurbishment and from initiatives underway to expand in commercial markets. Currently, we are developing a next generation opposed piston engine (Trident OP™) that, if successful, will provide increased opportunities in commercial power generation markets. In addition, Fairbanks Morse has an agreement with MAN Diesel that provides Fairbanks Morse with additional products for sale to the U.S. power generation market.

Drive Growth through Product Innovation

We seek to drive growth by enhancing our product and technology offerings. Within our Sealing Products segment, we are expanding the Garlock family of products to meet the needs of the food and pharmaceutical markets. We are also making distinctive improvements in several of our core product lines to maintain our competitive advantage in product performance. Recent examples include the new Evolution and Epix product lines. At Stemco, we have an established track record of new product development and a number of product innovation initiatives underway in our wheel-end, brake and suspension components groups. At Technetics, we are expanding our product offerings for the aerospace, semiconductor and nuclear markets through close customer collaboration and active partnerships with companies like Airbus, Applied Materials, and the French nuclear agency (CEA). In our Power Systems segment, we are working to commercialize our internally developed, next generation opposed piston engine, the Trident OP™. We plan to continue the development of proprietary products as a means to differentiate ourselves from our competitors and grow our business. These efforts are supported by an enterprise-wide focus on innovation led by one of our division presidents.

Capture Growth via Geographic Expansion

While our primary markets are the developed economies of North America and Europe, we have expanded selectively in Eastern Europe, Asia, South America, the Middle East and Africa since the 2002 spin-off from Goodrich. All of our operating divisions other than Fairbanks Morse and CPI have a presence in Asia where our focus, with the exception of Stemco, is serving the local market. In the case of Stemco, we operate two facilities in China that produce wheel-end bearings and air disc brake friction for export to the U.S. We will continue to expand geographically in areas, and with customers, that value our high-performance products and service capabilities.

Supplement Organic Growth with Strategic Acquisitions

In addition to new product development and geographic expansion, acquisitions provide a means for expanding our addressable market through adding new products and technologies and helping us enter new markets. We maintain a disciplined and conservative acquisition approach that is grounded in business strategy and that incorporates all aspects of the acquisition process, including target identification, valuation and negotiation, due diligence, integration and post-closing business planning and execution. Our acquisition focus has led to a ten-fold increase in Stemco’s addressable market over the past seven years, establishment of the Technetics Group to focus on high-performance sealing and related products, and expansion of Garlock’s pipeline products and hygienic technologies businesses. At Stemco, we have significant room to capture share in our expanded addressable market based on brand strength, channel strategy and sales excellence. Since the spinoff from Goodrich in 2002, we have invested approximately $768 million in acquisitions at an average price to EBITDA multiple of 7.3x before consideration of synergies.

Ongoing Focus on Cost Containment and Continuous Improvement

We continue to seek opportunities to lower manufacturing costs by optimizing our production footprint, implementing new manufacturing practices and processes and investing in capital equipment to increase manufacturing efficiencies and improve product quality. We will continue to manage our total supply spend through the work of our 40 category teams with the goal of realizing annual savings of 3% through the business cycle. In addition, we expect to continue to realize additional benefits from the investments made in new ERP systems over the past five years.

Use of Proceeds

We intend to use the net proceeds from this offering, together with borrowings under our Revolving Credit Facility, to fund the redemption of our $450 million aggregate principal amount 5.875% senior notes due 2022 (the “Outstanding Notes”).
