Atmus Filtration Technologies Inc.
Atmus Filtration Technologies Inc. designs and manufactures filtration products for commercial vehicles and off-highway equipment, with its business built around the Fleetguard brand. The company serves on-highway trucks and buses as well as agriculture, construction, mining, and power generation markets, supplying products that help lower emissions and protect engines and equipment. Its revenue mix is weighted toward the aftermarket, which creates a recurring replacement-part business alongside a smaller first-fit OEM component business. Atmus was separated from Cummins and began trading as an independent public company in 2023, carrying forward a long operating history in filtration and media technologies.

Customers
Atmus sells to original equipment manufacturers, their dealer networks, independent distributors, retailers and large end users that operate fleets or heavy equipment. Its core end markets are on-highway commercial vehicles and off-highway agriculture, construction, mining and power generation equipment. The aftermarket is the dominant channel because customers need recurring replacement filters and maintenance products to keep engines and equipment running efficiently. OEM relationships matter because first-fit placements create installed base, brand visibility and future aftermarket pull-through. Large fleets, mining companies and other high-utilization operators buy Atmus products to reduce downtime, extend service intervals and protect assets.

Strategy
Atmus is focused on expanding first-fit share in core markets while accelerating profitable aftermarket growth. The company is also investing in product development and technology transitions with OEMs, which helps it stay relevant as emissions and performance requirements change. Another priority is to deepen customer relationships through a multi-channel distribution model that improves product availability and supports recurring demand. The strategy is built around premium branded products, proprietary filtration media and a broad global footprint that can serve both OEM and aftermarket customers.
OEM placements create installed base, brand visibility and future aftermarket demand.
The aftermarket is the largest revenue pool and provides recurring replacement demand with better visibility.
Proprietary media, engineering and Fleetguard branding support pricing power and customer retention.
Margin resilience depends on managing supply chain complexity, material costs and manufacturing productivity.
Geography
Q1/2026Atmus operates with a global footprint and sells into multiple regions, but the filings provided do not disclose a country-by-country revenue split. The company emphasizes broad geographic coverage within regions, supported by technical centers, manufacturing and distribution relationships around the world. Its business is exposed to cross-border trade, tariffs and foreign exchange because products and components move through international supply chains and sales channels. Geography matters because demand is tied to regional truck, agriculture, construction and mining activity, while local dealer and distributor coverage affects aftermarket availability. The company also notes political and economic uncertainty in geographies where it has significant operations or product offerings.

Risks
Atmus faces meaningful customer concentration, with the filings specifically citing Cummins, PACCAR and the Traton Group, so the loss of a major OEM relationship could reduce first-fit volume and future aftermarket pull-through. Its business is also exposed to cyclical end markets such as trucking, agriculture, construction and mining, which can weaken demand when industrial activity slows. Because the company sources and manufactures globally, it is vulnerable to tariffs, trade restrictions, foreign exchange swings, supply interruptions and commodity cost inflation. Product quality, warranty claims, recalls and counterfeit sales are important risks in filtration because failures can affect engine performance, emissions compliance and customer trust. Cybersecurity, environmental regulation, labor issues and leverage from its term loan and revolver add further operational and financial risk.
