Customers
Enpro sells to industrial OEMs, distributors, engineering and construction firms, and end users that need highly reliable components in critical applications. Its customer base spans semiconductor equipment makers, commercial vehicle fleets and distributors, and regulated industries such as food, pharmaceuticals, biopharmaceuticals, aerospace and energy. The business depends on specified positions in customer designs and on aftermarket replacement demand, especially in wheel-end and sealing applications.
Buy cleaning, coating and refurbishing services and related components for advanced-node semiconductor manufacturing equipment; Enpro depends on a small number of large customers here.
Buy sealing products, mechanical seals and engineered components for demanding process environments where uptime and reliability matter.
Buy STEMCO wheel-end and suspension products, largely through distribution and replacement channels, to reduce failure risk and maintenance downtime.
Buy sanitary gaskets, hoses and fluid transfer products to meet hygiene and contamination-control requirements.
Buy high-reliability engineered solutions for critical applications where performance and certification are important.
Strategy
Enpro is repositioning its portfolio toward proprietary, high-barrier industrial technologies with recurring aftermarket exposure and secular growth end markets. Management is also pursuing acquisitions while using restructuring and site rationalization to improve efficiency and support new platforms in semiconductor and other growth areas.
Higher-spec products and specified positions support pricing power, margins and customer stickiness.
Replacement demand reduces cyclicality and improves cash flow visibility.
New platforms support long-term growth in semiconductor and adjacent markets.
M&A can add capabilities, broaden end markets and deepen technology content.
Geography
Q1/2026Enpro operates a global manufacturing and service footprint with 15 primary facilities in 8 countries, including the United States. In 2025, sales were concentrated in the United States at $647.1 million, with meaningful exposure to Asia Pacific, Europe and Rest of World, reflecting both semiconductor customer concentration in Asia and industrial demand across developed markets. The company also notes that about 41% of Sealing Technologies sales were delivered outside the United States.

Risks
Enpro is exposed to customer concentration in semiconductor-related surface technologies, where a small number of customers account for a large share of sales. It also faces raw-material inflation, supply-chain disruption, product liability and cybersecurity risks because its products are used in critical applications where failures can be costly and reputationally damaging.
- Raw material inflation and tariffsImpact: HighLikelihood: High
Higher input costs may not be fully passed through without losing customers, compressing margins.
Exposure: Sealing Technologies and manufacturing operations
- Supply-chain disruption and supplier dependenceImpact: HighLikelihood: High
Limited sources for certain materials increase the risk of production interruptions and missed deliveries.
Exposure: Global manufacturing footprint
- Customer concentration in Advanced Surface TechnologiesImpact: HighLikelihood: Medium
A small number of semiconductor equipment customers control much of the market, and one customer represented about 24% of consolidated net sales in 2025.
Exposure - Product liability and warranty claimsImpact: MediumLikelihood: Medium
Products are used in critical applications such as nuclear, oil and gas, automotive, aerospace and pharma.
Exposure: Sealing Technologies and STEMCO
- Cybersecurity and IT disruptionImpact: MediumLikelihood: Low
Attacks could halt production, corrupt data or impair customer service and create remediation costs.
Exposure: Enterprise systems and manufacturing operations
Accounting
Judgemental itemsAcquisition-heavy growth and shifting end-market demand can require impairment testing and write-downs.
Impact: Could materially affect earnings and equity if assumptions weaken
Site and function reorganizations create non-recurring costs that can distort period-to-period comparisons.
Impact: Affects operating income and adjusted earnings reconciliation
Critical-application products can generate claims and recall-related obligations that require estimates.
Impact: Can change SG&A and liabilities materially
Management excludes acquisition, restructuring, depreciation and other items when measuring segment performance.
Impact: Important for comparing operating trends to GAAP results
