What Atmus Filtration Technologies makes

Atmus Filtration Technologies is a filtration company built around the Fleetguard and Koch Filter brands, with a product line the company puts at roughly 25,000 items. The core is filtration for engines and equipment: fuel filters, lube and oil filters, air filters, hydraulic filters, coolant filtration, and fuel-water separators, sold both as first-fit parts on new machines and as aftermarket replacements to OEMs and their fleets. Atmus designs and manufactures a large share of its own filter media, including nanofiber and synthetic products branded NanoNet, NanoForce, and StrataPore, and in 2025 it launched a NanoNet N3 media generation.

The company serves on-highway and off-highway markets: truck and bus, agriculture, construction, mining, marine, and power generation. Alongside physical filters it sells maintenance chemicals and a digital service layer, FleetguardFIT, which adds remote diagnostics and analytics to filtration hardware. Atmus reports 350-plus engineers, scientists, and technical specialists across five technical centers, and more than 1,200 active or pending patents, a research base consistent with a supplier that develops its own media rather than assembling bought-in elements.

Financial performance

Atmus is publicly traded on the New York Stock Exchange under the ticker ATMU and reports audited financial results. For full-year 2025 the company reported revenue of $1,764 million, up 5.7 percent from $1,669 million in 2024, driven by higher volume and pricing. GAAP net income was $207 million, or $2.50 per diluted share, up from $185.6 million a year earlier. Adjusted EBITDA was $354 million, a 20.0 percent margin, up from 19.7 percent in 2024.

The balance sheet is conservative for an industrial manufacturer. Atmus ended 2025 with roughly $218 million in cash against about $618 million of debt, a net debt position near $400 million, or about 1.1 times adjusted EBITDA. Operating cash flow was $203 million and adjusted free cash flow $158 million for the year. The company pays a quarterly dividend and has authorized returns of capital to shareholders since becoming independent.

Ownership and history

Atmus traces its filtration heritage to 1958 and operated for decades as the filtration business of Cummins Inc., supplying engine filtration as a tier-1 supplier to commercial-vehicle and off-highway makers. Cummins took the business public through an IPO in May 2023, then completed a full separation on March 18, 2024, exchanging 67,054,719 Atmus shares to sever the remaining ownership tie. Since that date Atmus has been a fully independent, widely held public company headquartered at 26 Century Boulevard in Nashville, Tennessee.

The company employs approximately 4,500 people and operates on six continents, spanning filter and media manufacturing plants, technical centers, and distribution. Its leadership includes Steph Disher as Chief Executive Officer and President, Jack Kienzler as Chief Financial Officer, Greg Hoverson as Chief Technical Officer, and Kevin Carpenter as Chief Supply Chain Officer.

Known customers

Atmus sells through first-fit relationships with equipment makers and through the aftermarket, and it does not publish a customer-concentration roster. The clearest documented relationship is with its former parent.

Beyond that, Atmus states first-fit relationships with leading OEMs across truck, bus, agriculture, construction, mining, marine, and power generation, but names individual programs sparingly. Specific OEM program awards are not published, so no further customers are listed here.

Sourcing evidence

Atmus's US import record begins in May 2024, which lines up with the March 2024 separation from Cummins: the company started clearing ocean freight under its own name at that point. Since then US customs bills of lading record 956 sea shipments, most recently on September 21, 2026, at an average of about 2.07 TEU per shipment.

Seven of the recorded senders shown. The important reading is what the mix is: most of these senders are Atmus's own plants, its Fleetguard operation in India, the former Cummins Filtration plant at Quimper in France, and Atmus facilities in China, so the record maps the company's internal manufacturing network more than an external supply base. The genuinely third-party inputs are a narrower set of component suppliers, notably Superpar in Turkey for housings and Nanjing Jinsanli for rubber seals. Origin countries lead with India, France, and China.

Coverage caveats: these are US ocean-freight records only. Air, truck, and rail movements do not appear, some records name freight intermediaries rather than plants, and product categories come from declared manifest codes, which are noisy. Absence of a record is not evidence of absence.
