Atmus (ATMU) Q2 2026 earnings review
Record Sales and Raised Guidance Driven by Strong Execution
Atmus Filtration Technologies delivered a textbook beat-and-raise in Q2 2026. Top-line revenue accelerated to 16.4% YoY growth, reaching a record $528 million. The core Power Solutions business grew an impressive 7%, while the newly acquired Industrial Solutions segment contributed $42 million. Adjusted EPS of $0.82 easily outpaced last year's $0.75. Backed by excellent free cash flow generation, management confidently raised the floor on full-year revenue, margin, and earnings guidance.
🐂 Bull Case
The Koch Filter acquisition is already paying dividends. The Industrial Solutions segment added $42M in Q2 and management reaffirmed expectations for this segment to hit up to $165M for the full year, diversifying the revenue base beyond on-highway truck markets.
Gross margin expanded to 29.2% from 28.9% YoY. Management successfully leveraged pricing power and higher volumes in the legacy Fleetguard business to offset rising manufacturing and material costs.
🐻 Bear Case
The newly acquired Industrial Solutions segment saw its Adjusted EBITDA margin drop sequentially from 21.9% in Q1 to 18.9% in Q2, dragging down the total company margin.
Despite margin resilience, management explicitly cited higher materials and manufacturing costs as a headwind, signaling that the macroeconomic input cost inflation anticipated in previous quarters is beginning to bite.
⚖️ Verdict: 🟢
Bullish. Atmus is proving it can seamlessly integrate a major acquisition while defending its core market. Double-digit top-line growth, expanding gross margins, and raised full-year guidance across all key metrics make this a highly attractive print.
Key Themes
Power Solutions Rebounding and Accelerating
The legacy Power Solutions segment, featuring the Fleetguard® brand, generated $486 million in revenue, up 7.1% YoY from $453.5 million. This represents accelerating growth compared to Q1's 5.4% print. Higher volumes and successful pricing actions powered the top-line, indicating that the anticipated pre-buy cycle ahead of 2027 emissions standards may be taking effect.
Industrial Solutions (Koch Filter) Driving Top-Line Diversification
The Koch Filter® acquisition continues to serve as a massive growth engine, contributing $42.4 million to Q2 sales. This segment brings critical exposure to high-growth industrial HVAC applications, data centers, and power generation environments, structurally shifting Atmus away from a purely cyclical truck filtration supplier.
Sudden Margin Compression in Industrial Segment
While Koch Filter's revenue contribution is strong, profitability took a hit. Industrial Solutions Adjusted EBITDA margin compressed significantly, decelerating from an impressive 21.9% in 26Q1 to 18.9% in 26Q2. This contradicts the high-margin narrative from Q1 and requires scrutiny on whether integration costs, mix shift, or pricing pressure caused the 300 basis point sequential drop.
Cash Generation and Capital Returns Remain Robust
Adjusted Free Cash Flow roughly doubled YoY, accelerating to $67 million in 26Q2 compared to $36 million in 25Q2. With separation costs related to Cummins effectively dropping out of the equation, the company efficiently converted income to cash. This allowed for $13 million in share repurchases in the quarter, leaving $49 million on the board authorization, plus steady dividend payments.
Manufacturing and Material Cost Inflation
Management's primary risk flag from early 2026—input cost pressure on materials—has officially materialized in the P&L. Gross margin improvements from volume and pricing were partially offset by higher materials and manufacturing costs. As global supply chain dynamics remain fluid, the company's ability to maintain 'price-cost neutrality' will be rigorously tested in the second half of the year.
Macroeconomic and Tariff Complexities
Though not explicitly quantified in the release, Atmus continues to navigate a complex macroeconomic environment involving volatile currency impacts and historical tariff pressures. Favorable currency was a tailwind for gross margins this quarter, but this represents a macro variable outside of management's control that could reverse in future periods.
Other KPIs
Stable to slightly accelerating. Improved from 28.9% in the prior year quarter. The 30 basis point expansion highlights strong pricing power and the accretive nature of the Koch Filter acquisition, which fully offset the sting of rising raw material costs.
Accelerating. Up 86% YoY from $35.5 million in 25Q2. The significant reduction in one-time separation costs from Cummins ($3M last year to negligible this year) combined with raw earnings power drove massive cash conversion.
Guidance
Accelerating. Management raised the full-year guidance range from the previous $1,945M-$2,015M. At the midpoint ($2,002.5M), this implies ~13.5% YoY growth over FY25's $1,764M. The raise was driven strictly by the core Power Solutions segment, as the Industrial segment guide remained unchanged.
Accelerating. Up from the prior outlook of $1,790M-$1,850M. This implies organic growth of roughly 4.4% at the midpoint, suggesting high confidence in H2 first-fit market recovery and aftermarket share gains.
Stable. The range was tightened from 19.5%-20.5%. The 20.0% midpoint implies zero margin expansion vs FY25, indicating that incremental gross profits are being reinvested into growth initiatives or absorbed by input cost inflation.
Accelerating. The floor was raised by $0.10 from the previous $2.75-$3.00 guide. This implies robust bottom-line confidence fueled by share repurchases and consistent operating performance.
Key Questions
Industrial Solutions Margin Contraction
The Industrial Solutions segment saw its Adjusted EBITDA margin drop sequentially from 21.9% to 18.9%. Was this driven by temporary integration costs, a shift in product mix, or heightened competitive pricing pressure?
Material Cost Inflation Timeline
You noted that higher materials and manufacturing costs offset some gross margin gains. What specific commodities are driving this, and do you expect a timing lag in your ability to pass these costs through to customers in H2?
Capital Allocation Strategy
With $49 million remaining on the share repurchase authorization and an increasingly strong cash flow profile, are you looking to aggressively deploy the remainder of that authorization this year, or preserve capital for further bolt-on industrial acquisitions?
