Atmus Filtration Technologies Inc. (ATMU) - 2025 Annual Report Summary

Business Context and Reporting Period

This summary covers the fiscal year ended December 31, 2025, for Atmus Filtration Technologies Inc., a global leader in filtration products for on-highway commercial vehicles and off-highway equipment (agriculture, construction, mining, power generation). The company operates primarily under the Fleetguard brand. Approximately 86% of net sales are generated in the aftermarket (replacement parts), providing a recurring revenue base, while 14% comes from first-fit sales to Original Equipment Manufacturers (OEMs). The company is a standalone public entity following its separation from Cummins Inc., with full separation completed in March 2024.

Key Financial Metrics (Year Ended Dec 31, 2025)

Material Changes vs. Prior Period

• Revenue Growth: Net sales increased by 5.7% ($94.7 million) driven by higher volumes ($51.9 million) and favorable pricing ($50.0 million), partially offset by unfavorable currency impacts ($7.3 million).
• Margin Expansion: Gross margin improved by 0.5 percentage points to 28.2%, aided by pricing initiatives and lower one-time separation costs, despite higher logistics and duty costs ($36.2 million).
• Expense Management: Selling, general, and administrative (SG&A) expenses decreased by 1.8% due to lower one-time separation and restructuring costs ($11.6 million reduction), offset by increased people-related expenses.
• One-Time Items: The company incurred $15.5 million in one-time separation costs and $8.4 million in long-lived asset impairment charges related to idled machinery.
• Debt Reduction: Total debt decreased by $22.5 million due to principal payments on the term loan.

Guidance, Outlook, and Risks

Outlook and Strategy: Management expects slow growth in global aftermarkets to continue into 2026, with first-fit demand remaining at reduced levels due to market cyclicality. The company is focused on expanding into industrial filtration markets and transforming its supply chain. A significant strategic move occurred in January 2026 with the acquisition of Koch Filter Corporation for approximately $450 million to expand into industrial air filtration.

Capital Structure Update: In January 2026, Atmus entered into an Amended and Restated Credit Agreement, increasing the term loan facility to $1.0 billion and the revolving credit facility to $500 million, maturing in 2031.

Key Risks:

• Customer Concentration: Three customers (Cummins, PACCAR, and the Traton Group) accounted for approximately 46.6% of 2025 net sales. Cummins alone represented 18.8%.
• Technology Transition: The shift toward electrified powertrains and alternative fuels poses a long-term risk to demand for internal combustion engine filtration products.
• Geopolitical and Trade: Exposure to tariffs, trade barriers, and political instability in key markets (Mexico, China, India) could impact costs and demand.
• Joint Ventures: Significant earnings are derived from unconsolidated joint ventures in China and India, which the company does not directly control.

Investor Verification Checklist

• Verify the integration progress and financial impact of the Koch Filter Corporation acquisition closed in January 2026.
• Monitor the stability of the relationship with Cummins, given its 18.8% share of sales and the competitive bidding process for future first-fit programs.
• Assess the impact of tariffs and trade policies on logistics costs and pricing power, particularly for products manufactured in Mexico and China.
• Review the company's progress in diversifying revenue streams beyond internal combustion engine filtration to mitigate risks from electrification trends.
• Confirm the sustainability of free cash flow generation given the increased debt load from the new credit facility and acquisition financing.
