Future Outlook

Aftermarket demand is expected to remain in a period of slow growth into 2026, while first-fit demand is anticipated to stay at reduced levels in 2026 due to overall market cyclicality. Overall supply chain conditions are largely stable, but logistics costs increased in 2025 due to the standalone distribution network and tariffs. The company does not expect to incur additional one-time separation expenses or capital expenditures in future periods, as the transition services agreement with Cummins concluded in September 2025.

Management Comments

• Atmus is one of the global leaders of filtration products for on-highway commercial vehicles and off-highway agriculture, construction, mining and power generation vehicles and equipment.
• Atmus designs and manufactures advanced filtration products, principally under the Fleetguard brand, that enable lower emissions and provide superior asset protection.
• Atmus believes that Fleetguard is a premium, leading brand that is strongly associated with reliability and strong performance.
• Atmus leadership team has the ability to develop and execute its strategic vision and aims to create long-term shareholder value.
• Atmus believes that the composition of its workforce gives it advantages relating to cost and capability when compared to its peers.
• Atmus is committed to continually improving the health and safety of its work environment, taking action to achieve its goal that nobody gets hurt.

Industry Context

StockSavvy.ai notes that Atmus's strategic expansion into industrial air filtration with the Koch Filter acquisition aligns with broader industry trends of diversification and addressing evolving market needs beyond traditional internal combustion engine applications. The continued softness in aftermarket and first-fit demand for on-highway and off-highway vehicles reflects the cyclical nature of these heavy industries, which are sensitive to macroeconomic factors like freight activity, infrastructure investment, and commodity prices. The company's focus on technology leadership and a strong aftermarket presence positions it well against competitors like MANN+HUMMEL, Donaldson, Parker, and MAHLE, especially as the industry navigates the transition towards lower emissions and alternative power sources.

Comparison to Industry Standards

• Atmus's 2025 net sales growth of 5.7% and net income growth of 11.7% demonstrate solid performance, potentially outpacing some competitors in a 'slow growth' aftermarket environment. For example, Donaldson Company, Inc. (DCI), a direct competitor, reported a 2.5% sales increase in its fiscal year 2023 (ended July 31, 2023), suggesting Atmus's growth rate is competitive or stronger.
• The gross margin improvement to 28.2% is a positive indicator, though specific competitor gross margins would be needed for a direct benchmark. However, it shows internal efficiency gains.
• The acquisition of Koch Filter Corporation for $450 million to enter industrial air filtration is a significant strategic move, comparable to how other filtration giants like MANN+HUMMEL or Parker Hannifin (with its Racor division) have diversified their portfolios to capture broader market opportunities and mitigate risks from the energy transition in traditional engine markets.
• Atmus's 86% aftermarket sales concentration is a strong point, providing more stable, recurring revenue compared to companies with higher first-fit exposure, which are more susceptible to OEM production cycles.
• The company's investment in R&D ($40.7 million in 2025) for new technologies, including electric and hydrogen-powered vehicles, is crucial for long-term competitiveness against peers who are also adapting to the energy transition.
