Atmus: A Record Quarter, a New Segment, and a Lingering Middle East Shadow
A Record Quarter in a Drawdown
Atmus Filtration Technologies delivered a record second quarter—sales of $528 million, up 16.4% year-over-year, with adjusted EBITDA of $109 million and EPS of $0.82. Yet the stock has been in a persistent drawdown, down about 21% over the last 90 days. “I am pleased to share that we achieved record sales in the second quarter and delivered strong results among our key metrics, including adjusted EBITDA, free cash flow and EPS.” — Stephanie Disher, Chief Executive Officer · 2026-08-07 The market seems to be looking past the headline beat and focusing on the softer second-half outlook and the continued drag from the Middle East conflict. The company's cyclical recovery in first-fit markets is showing early signs, but the aftermarket remains flat—a key variable for a business where roughly 85% of Power Solutions revenue comes from aftermarket.
The Industrial Pivot: Koch Filter and the New Growth Engine
The most significant change at Atmus is the launch of its Industrial Solutions segment, built around the Koch Filter acquisition closed earlier this year. This is a deliberate strategic pivot into industrial filtration, a market the company targets for its data center, healthcare, and commercial HVAC end-markets. “We continue to see value creation opportunities from Koch filter's deep industry experience, combined with our filtration capabilities and global footprint, which will provide ongoing benefits for all stakeholders.” — Stephanie Disher, Chief Executive Officer · 2026-08-07 The integration is ahead of schedule—over 95% of the transition services agreements have been exited—and management is already turning to growth initiatives, including exposing the business to high-growth end-markets like data centers. This is a clear company-unique theme; the acquisition of Koch Filter has been the top keyword on this name for two consecutive quarters. Prior commentary shows this has been a long-awaited move: in February's call, Steph Disher noted the company was "very excited about the Cook acquisition" and the opportunity to combine filtration media expertise with Koch's product range. The Industrial Solutions segment is still small—$42 million in Q2, with an 18.9% segment EBITDA margin—but management expects full-year revenue of $155–$165 million, and the strategy is to build a platform of scale through further bolt-on acquisitions.
Middle East, Tariffs, and the Margin Bridge
The second-quarter beat came with a notable caveat: the Middle East conflict is now a tangible drag on both costs and joint venture income. CFO Jack Kienzler noted that "we continue to see some elevation in our cost base associated with some commodities and a lot of that is driven by the ongoing conflict in the Middle East," and that this is a primary driver of the moderated second-half margin guide. The company also lowered its full-year adjusted EBITDA margin guide to 19.75%–20.25% (from a previous range, with the top end trimmed by 25 bps). Tariff refunds, meanwhile, have been immaterial so far—“we've received an immaterial amount of tariff refund” — Jack Kienzler, Chief Financial Officer · 2026-08-07—but the company maintains its price-cost neutral approach to tariffs. This is consistent with prior quarters; in May's call, Jack explained that the overall tariff impact would be "substantially neutral" and that the company would "continue to evaluate the potential treatment of those refunds." The price realization has been strong in the first half at just over 2%, but the full-year guide implies a moderation to around 1.5% as tariff-driven pricing rolls off.
On the demand side, first-fit markets are finally showing the long-awaited cyclical upturn, but the aftermarket remains subdued. Steph Disher said, “We are starting to see signs of health in the overall freight market... however, we have yet to see a significant inflection.” — Stephanie Disher, Chief Executive Officer · 2026-08-07 This flat aftermarket stance is unchanged from prior quarters, and the company continues to rely on share gains (1%–2%) to drive growth. The record quarter was supported by 3% pricing, 2% volume, and 2% FX in Power Solutions, but the market is likely concerned about the sustainability of that pricing in H2 as tariffs normalize.
Financial Position and Outlook
Despite the macro headwinds, Atmus is generating strong free cash flow—$67 million in Q2—and has maintained a healthy balance sheet. Net debt to adjusted EBITDA stands at 1.9x, and the company plans to use surplus cash to pay down gross debt while continuing to return capital. Free cash flow margin came in at 4.6% in Q2 (up 1.3pp y/y), though it remains below the 11.3% peak seen in 2023. The company's leverage is modest, but interest coverage has fallen from double-digit levels to 5.4x as net debt has grown with the Koch acquisition. The full-year revenue guide of $1.975–$2.03 billion implies ~13.5% growth, with adjusted EPS of $2.85–$3.00. The market appears to be discounting the margin pressure and the uncertainty around the Middle East, but the strategic pivot into industrial filtration remains a compelling long-term story.
Sales in the second quarter were a record $528 million compared to $454 million during the same period last year, an increase of 16.4%.
Ultimately, this is a company in transition—executing on a new growth axis while managing geopolitical and tariff noise. The record quarter and the successful early integration of Koch Filter are offset by a cautious second-half guide and a stock that is already pricing in some of the risk. The next few quarters will be telling: can the first-fit recovery accelerate, and can tariff refunds and pricing discipline sustain the margin? For now, the story is one of measured optimism with a clear strategic direction.
