Atmus Filtration Technologies Inc.: what insiders have been doing
This page follows insider dealings at Atmus Filtration Technologies Inc. as filed with SEC (Form 4), a company from the Industry sector. The last twelve months, up to 18 October 2026, brought 25 filings signed by 11 insiders.
Purchases and sales both appear in the filings: 1 purchase (1 insider, €86k) and 6 sales (5 insiders, €1.6M). Taken together, the sales exceed the purchases by €1.5M. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Among those who bought: 1 senior executive. One trade stands out by size: a sale of €999k from Disher Stephanie, disclosed on 2 June 2026, or 0.024% of market capitalisation.
The clock since the last published purchase (13 August 2026) now reads 65 days. Typically, a trade is published a median of 1 day after it takes place. The legal deadline for a Form 4 is two business days after the transaction. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.
Compared with its exchange (5,811 companies, median 19 filings), a count of 25 filings is above the norm. Since 2023, the database holds 5 purchases and 7 sales by insiders of the company. For the fiscal year to 31 December 2025, the annual 10-K puts revenue at 1.76 bn USD and net income at 207.4 m USD, and the dividend at 0.21 USD per share.
Elsewhere in the same sector, our signals recently picked up insider purchases at Tennant Co and Butler National Corp. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.

About Atmus Filtration Technologies Inc.
Atmus Filtration Technologies Inc. (NYSE: ATMU) is a U.S.-listed industrial company headquartered in Nashville, Tennessee, in the United States. The business was founded inside Cummins in 1958 and became an independent company in 2023, giving it a long operating history while also making the post-separation story relatively recent. That heritage matters: Atmus combines more than 65 years of filtration and media technology experience with a sizeable intellectual-property base and a legacy of engineering-led product development. ([atmus.com](https://www.atmus.com/who-we-are))
Atmus operates through two business segments. Power Solutions serves the global on-highway and off-highway markets through the Fleetguard® brand, while Industrial Solutions focuses on higher-growth end markets such as commercial and industrial HVAC, data centers, and power generation, notably through the Koch Filter® brand. Its portfolio spans oil, fuel and air filters, hydraulic filtration, crankcase ventilation modules, coolant-related products, filter media, and aftermarket support solutions. Management emphasizes that its filtration technologies are designed to extend service intervals, lower maintenance costs, and increase uptime for end customers.

From a competitive standpoint, Atmus is positioned as a specialist rather than a broad diversified industrial. Its Fleetguard brand is an important differentiator, supported by a reputation for reliability and performance, a broad product range, and strong relationships with leading OEMs. The company states that its major OEM partners include Cummins, Daimler, Deere, Komatsu, Paccar/DAF, the Traton Group, Stellantis, and Volvo. In 2024, those customers accounted for about 68% of net sales, underscoring both the durability of these relationships and the concentration inherent in the model. Atmus also benefits from a large aftermarket footprint, which represents the majority of sales and supports recurring demand beyond original equipment cycles. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1921963/000192196325000056/atmu-arsfy24x2025x04x01x12.pdf))
Geographically, Atmus has a broad global footprint across six continents, with 14 wholly owned manufacturing sites and 10 joint-venture facilities. This network supports both OEM and aftermarket channels and helps the company stay close to customers across truck, bus, agriculture, construction, mining, marine, and power generation equipment markets. The company’s international presence is strategically important, but it also means exposure to foreign exchange volatility and uneven industrial demand by region. ([atmus.com](https://www.atmus.com/who-we-are))
Recent developments have been constructive. Atmus reported full-year 2024 sales of $1.67 billion and improved operating profitability, while continuing to unwind one-time costs associated with the separation from Cummins. The company’s latest disclosures also highlight its position as a global leader in filtration and media solutions, as well as its continued focus on shareholder returns and execution discipline. For investors following U.S. industrial equities, Atmus offers a relatively focused filtration platform with premium brands, a global aftermarket base, and exposure to both cyclical equipment markets and secular demand for filtration performance.
