Atmus Filtration Earnings Call Highlights Growth and Deals

Atmus Filtration Technologies, Inc. ((ATMU)) has held its Q4 earnings call. Read on for the main highlights of the call.

Atmus Filtration Technologies struck an upbeat tone on its latest earnings call, balancing solid revenue growth, rising earnings, and robust cash generation with a candid view of softer end markets and cost pressures. Management leaned on the strategic Cook Filter acquisition, strong liquidity, and clear 2026 guidance to argue that growth initiatives and product wins outweigh macro and tariff-related headwinds.

Cook Filter Deal Opens New Industrial Growth Engine

Atmus closed its acquisition of Cook Filter in early January, creating a new Industrial Solutions segment and extending its reach into industrial air filtration. The deal brings exposure to commercial and industrial HVAC, plus about 8% of sales tied to data centers growing at a high‑teens rate, and management says integration and procurement synergies are already identified.

Fourth-Quarter Sales Climb Nearly 10%

Fourth-quarter revenue rose to $447 million from $407 million a year ago, a 9.8% increase that reflected both pricing power and demand resilience. Pricing contributed roughly 5 percentage points of growth, volumes added about 4 points, and foreign exchange delivered another 1 point, underscoring a balanced mix of drivers.

Profitability Holds Firm With Margins at 20%

Atmus delivered adjusted EBITDA of $85 million in Q4, sustaining a solid 19.1% margin that was flat versus last year despite cost headwinds. For the full year, adjusted EBITDA rose to $354 million from $330 million, and the company lifted its full‑year margin to 20.0% from 19.7%, signaling disciplined execution.

EPS and Free Cash Flow Move Higher

Adjusted earnings per share improved to $2.73 for the year, up 9.2% from $2.50, while Q4 adjusted EPS climbed to $0.66 from $0.58. Adjusted free cash flow jumped 37.4% year over year to $158 million, with fourth‑quarter adjusted FCF ticking up to $31 million, giving Atmus more firepower for deals, buybacks, and debt reduction.

Shareholder Returns and Buybacks Stay in Focus

The company returned $78 million to investors in 2025, including $61 million via share repurchases and $17 million in dividends, underscoring its commitment to capital returns. Management still has $69 million authorized for buybacks and plans to repurchase between $20 million and $40 million of stock in 2026, subject to market conditions and leverage goals.

2026 Outlook: Double-Digit Revenue, Stable Margins

For 2026, Atmus is guiding total revenue to a range of $1.945 billion to $2.015 billion, implying 10% to 14% growth versus 2025 on the back of Cook and modest underlying gains. Power Solutions is expected to reach $1.79 billion to $1.85 billion, while the new Industrial Solutions segment, including Cook, should contribute $155 million to $165 million.

Technology Edge With Award-Winning NanoNet N3

Product innovation remains a key plank of the strategy, highlighted by the NanoNet N3 media launch, which enables more compact filter designs and longer service life. NanoNet N3 received ‘Product of the Year’ honors from the World Filtration Institute, supporting Atmus’s push for first‑fit wins and deeper OEM relationships.

Supply Chain Upgrade and Ample Liquidity

Management reported completion of the transition to a global Atmus distribution network, which is expected to improve on‑shelf availability and service levels. Post‑Cook financing leaves the company with an amended credit facility, about $201 million in cash, roughly $701 million in total liquidity, and leverage around 2.1x, with plans to deleverage through EBITDA growth and cash generation.

End Markets Remain Soft, Freight Recovery Elusive

Despite internal progress, Atmus described its global end markets as challenging and said it has yet to see a sustained rebound in freight activity. The company expects aftermarket demand to be relatively flat year over year and anticipates heavy‑duty first‑fit weakness in the first half, with improvement skewed toward the back half of 2026.

Tariff Normalization Caps Pricing Upside

Management noted that 2025 benefited from elevated pricing, partly linked to tariffs that will not fully carry into 2026 as trade agreements and offsets change. For 2026, Atmus is planning on about 1% core pricing and aims to remain price‑cost neutral on tariffs, injecting some uncertainty into how much pricing can contribute to future growth.

One-Time Charges Hit Other Income Line

Fourth-quarter other expense swung to $10 million from $5 million of income a year earlier, weighed down by unfavorable FX translation and an $8 million impairment on idled equipment. For the full year, other income flipped to an $8 million expense from $7 million of income, though the impairment is excluded from adjusted results that investors tend to focus on.

Cost Inflation in Logistics and Manufacturing

Gross margin expansion was tempered by higher logistics and duties as well as elevated manufacturing costs, which offset some of the gains from pricing and volume. These pressures highlight the operational backdrop Atmus faces, even as it leverages scale, procurement, and network changes to defend profitability.

Flat EBITDA Midpoint Signals Investment Phase

While revenue is guided up double digits, the midpoint of 2026 adjusted EBITDA guidance is roughly flat year over year, pointing to limited near‑term margin expansion. Management cited increased investments to fuel growth and planned pulsing of manufacturing volumes as key factors, suggesting a focus on long‑term positioning over short‑term margin optics.

Higher Tax Rate and Separation Costs Weigh on Results

The effective tax rate rose to 22.1% from 21.0%, reflecting an unfavorable geographic earnings mix that trimmed net income. The year also included $16 million of one‑time separation costs and $10 million of separation‑related capital expenditures that were adjusted out of free cash flow, but still represented real cash uses in the period.

Guidance Signals Confident but Measured Growth Path

Looking ahead, Atmus expects 2026 revenue growth to be driven by roughly 1% pricing, 1% FX tailwind, 1% to 4% from industrial markets, and 1% to 2% share gains, while heavy‑ and medium‑duty markets remain flat to modestly up and aftermarket trends stay flat. The company is targeting an adjusted EBITDA margin of 19.5% to 20.5%, adjusted EPS of $2.75 to $3.00, and $20 million to $40 million of share repurchases, while keeping leverage around 2.1x and preserving strong liquidity.

Atmus’s earnings call painted a picture of a filtration specialist leaning into acquisitions, product leadership, and disciplined capital allocation to build value through a choppy macro backdrop. With Cook Filter broadening its portfolio and 2026 guidance calling for double‑digit top‑line growth and steady margins, investors are being asked to look through near‑term cost and market pressures to a more diversified, cash‑generative future.
