Atmus (ATMU) Q1 2024: Aftermarket Share Gains Offset Softer Freight, Guidance Holds at $1.61B–$1.675B

Atmus’ first full quarter as a standalone company saw aftermarket share gains counterbalance freight and first fit softness, sustaining guidance despite mixed end-market signals. Separation from Cummins is largely complete, with operational independence driving new commercial wins and cost transformation. Management’s focus on aftermarket agility, disciplined capital allocation, and expanding into industrial filtration sets a clear forward agenda for both organic and inorganic growth.

Summary

  • Aftermarket Agility Drives Share Gains: Tailored distribution and customer focus offset market headwinds.
  • Separation Execution Maintains Margin Trajectory: Standalone cost absorption and transformation programs support stable profitability.
  • Industrial Filtration Expansion Remains a Priority: M&A pipeline and capital allocation discipline underpin future growth bets.

Business Overview

Atmus Filtration Technologies is a global supplier of filtration products and solutions for commercial vehicles and industrial applications. The company generates revenue primarily through two segments: aftermarket (replacement filters and parts for vehicles already in service, which delivers recurring revenue) and first fit (supplying filtration systems to original equipment manufacturers, or OEMs, for new vehicles). Atmus is a leader in fuel filtration and crankcase ventilation products, with a growing footprint in both on-highway and off-highway markets, and is actively expanding into broader industrial filtration end markets.

Performance Analysis

Q1 2024 marked Atmus’ first full quarter as an independent entity, with sales rising modestly despite industry-wide freight softness and first fit market declines. Aftermarket share gains—particularly in North America—offset volume headwinds, as the company leveraged its Fleetguard brand and revamped distribution to capture customer demand. Pricing actions and favorable currency also contributed, while commodity cost relief was partially offset by higher freight and manufacturing expenses.

Standalone costs associated with the Cummins separation were front-loaded into the quarter, with $6 million booked and total 2024 one-time costs now expected at $10–$20 million, up from prior guidance. Adjusted EBITDA margin held steady at 18.8%, reflecting operational discipline amid ongoing investment in automation and supply chain transformation. Free cash flow was negative due to working capital and incentive compensation, but management emphasized these were transitional impacts tied to the separation process and payroll changes.

  • Aftermarket Outperformance: Share gains in aftermarket, especially in the U.S., more than offset market declines, validating the distribution and customer focus strategy.
  • First Fit Headwinds: U.S. heavy-duty truck first fit outlook improved slightly, but overall first fit volumes remain pressured, with softness concentrated in China and Europe.
  • Separation-Related Costs: Standalone cost absorption is peaking in early 2024, with tapering expected as transition services wind down and new IT systems come online.

Overall, Atmus’ ability to hold revenue guidance and margin targets in the face of mixed market signals and separation complexity reflects resilient execution and a clear focus on long-term value creation.

Executive Commentary

"Our continued market share gains are offsetting some of the market weakness. Demand in the first fit markets has started to show signs of slowing in the US. In India, markets remain robust, while in China, the market continues to fall short of expectations."

Steph Disher, Chief Executive Officer

"Our cash position and continued strong performance during the first quarter of 2024 has resulted in a net debt to adjusted EBITDA ratio of 1.5 times for the trailing 12 months ended March 31st. Our balance sheet provides us with operational flexibility as we focus on value creation and delivering total shareholder value by deploying capital for continued organic growth and strategic inorganic initiatives."

Jack Hinzler, Chief Financial Officer

Strategic Positioning

1. Aftermarket Share and Distribution Transformation

Atmus’ largest profit engine remains its aftermarket business, with management attributing outperformance to a re-engineered distribution network and a customer-first approach. The shift to dedicated distribution centers—now covering over 80% of volume—has unlocked product availability and responsiveness, particularly in the U.S. and emerging markets. Fleetguard, the company’s flagship aftermarket brand, is benefiting from targeted marketing and technology differentiation, supporting further share capture.

2. First Fit Strategy and Platform Wins

First fit exposure is being actively managed for technology-led wins, focusing on new vehicle platforms where Atmus’ filtration and crankcase ventilation products offer a competitive edge. The company recently secured a major contract with a global OEM for both North America and Europe, marking progress in diversifying away from its historical Cummins dependency. However, management remains cautious on first fit volumes, especially in China and Europe, and is prioritizing high-value, high-retention platforms.

3. Supply Chain and Operational Efficiency

Operational transformation is a core pillar, with investment in automation (such as the fully automated green cartridge line in France) and procurement discipline driving cost efficiency. The transition from Cummins’ shared services is nearly complete, with IT, HR, and distribution now largely standalone, positioning Atmus for faster decision-making and margin resilience.

4. Industrial Filtration M&A Pipeline

Expansion into industrial filtration markets is a top strategic priority, with management evaluating a pipeline of $100–$150 million acquisition targets. The approach is programmatic and disciplined, aiming for one to two bolt-on deals per year to build out the company’s footprint in attractive adjacent markets. No deals have closed yet, but leadership’s tone signals readiness to deploy capital as opportunities align with strategic fit and return thresholds.

Key Considerations

This quarter underscored Atmus’ ability to deliver stability and operational progress despite external and internal transition headwinds. The company’s high aftermarket mix, disciplined approach to first fit, and readiness for M&A are central to its investment thesis.

Key Considerations:

  • Aftermarket Share Gains Are Structural: Distribution upgrades and customer focus are driving recurring revenue and margin durability.
  • Separation Costs Are Transitory: Standalone cost absorption is peaking, with normalization expected by year-end as transition services phase out.
  • First Fit Remains Selective: Technology-driven wins are prioritized over volume, mitigating exposure to cyclical OEM demand swings.
  • Capital Allocation Flexibility: $549 million in liquidity and a 1.5x net leverage ratio position Atmus for both organic and inorganic growth, with shareholder returns under board review.

Risks

Atmus faces ongoing risks from freight market volatility, especially if North American demand recovery stalls or China remains weak. Separation-related execution risks persist as IT and distribution transitions complete, and any delays could impact cost or service levels. Industrial filtration M&A introduces integration and return risk, especially as the company moves beyond its core. Extended periods of macroeconomic softness or OEM destocking could pressure both segments.

Forward Outlook

For Q2 2024, Atmus guided to:

  • Revenue in the range of $1.61 billion to $1.675 billion for the full year
  • Adjusted EBITDA margin of 18.25% to 19.25%

For full-year 2024, management maintained guidance:

  • Adjusted EPS of $2.10 to $2.35

Management highlighted several factors that will shape the year:

  • Aftermarket expected to be flat to up 2%, down slightly from prior guidance, with Q2 seen as a key inflection point for freight activity
  • First fit U.S. heavy-duty truck outlook improved modestly, but softness remains in China and Europe

Takeaways

Atmus’ Q1 demonstrated the resilience and flexibility of its aftermarket-driven model, with operational independence enabling more targeted growth and cost initiatives. Share gains in aftermarket and disciplined first fit wins are offsetting macro and separation pressures, while the M&A pipeline and capital allocation flexibility provide future upside.

  • Aftermarket Engine Remains Robust: Distribution and customer execution are driving recurring growth despite freight and OEM softness.
  • Separation Nears Completion: One-time costs are front-loaded, with margin and cash flow normalization expected as transitions finish in 2024.
  • Industrial Filtration Expansion Is the Next Catalyst: Watch for M&A execution and integration as Atmus deploys its balance sheet for growth.

Conclusion

Atmus delivered a stable, strategically aligned quarter, using aftermarket strength and operational transformation to navigate a complex market and internal transition. The company’s focus on margin, capital discipline, and expansion into new filtration markets positions it for long-term value creation, with separation risks receding and growth levers coming into clearer focus.

Industry Read-Through

Atmus’ results highlight the defensive strength of aftermarket-heavy business models in cyclical industrial sectors, especially when paired with distribution agility. OEM suppliers with high recurring revenue and technology differentiation are better positioned to weather freight and industrial volatility, while those with heavy first fit exposure may see sharper swings. The rising importance of supply chain autonomy and automation is a key theme for industrial peers navigating spin-offs or separation events. Finally, the disciplined approach to industrial filtration M&A underscores the need for bolt-on, programmatic deals rather than transformative bets as a path to adjacent market expansion.
