Atmus Filtration Technologies delivered a fourth quarter that exceeded Wall Street’s expectations, with management attributing the strong results to disciplined execution and the successful rollout of its four-pillar growth strategy. CEO Stephanie Disher highlighted the company’s expansion into industrial air filtration through the acquisition of Cook Filter and the launch of the next-generation NanoNet N3 media as key drivers. Additionally, improvements in supply chain management and increased pricing helped offset continued softness in global markets. Disher noted, “We continue to deliver strong outperformance in the fourth quarter, which drives higher sales even as soft market conditions persisted in most of our global markets.”

While we enjoy listening to the management's commentary, our favorite part of earnings calls are the analyst questions. Those are unscripted and can often highlight topics that management teams would rather avoid or topics where the answer is complicated. Here is what has caught our attention.

Our Top 5 Analyst Questions From Atmus Filtration Technologies’s Q4 Earnings Call

• Tami Zakaria (JPMorgan) asked about the contribution of data center filtration in Cook Filter and its growth trajectory. CEO Stephanie Disher explained that 8% of Cook’s revenues are tied to data centers, growing at a high teens rate, and emphasized ongoing product development for this segment.
• Tami Zakaria (JPMorgan) followed up on pricing, questioning the impact of tariff rollbacks. Disher clarified that the 1% pricing guidance reflects core pricing and not additional tariff-related increases, as the company aims to remain price-cost neutral on tariffs.
• David Emerson Ridley-Lane (Bank of America) inquired about potential gross margin synergies from insourcing filtration media at Cook. Disher highlighted that most synergies are expected from procurement and innovation efforts, with integration workshops underway to unlock new opportunities.
• Robert Brooks (Northland Capital Markets) questioned the conservatism of Industrial Solutions’ sales guidance. Disher responded that the range reflects both integration timing and market variability, with growth pulsing around GDP and share gains.
• Siobhan Srivastava (R.W. Baird) asked about the drivers of flat adjusted EBITDA guidance and possible self-help actions. CFO Jack Kienzler pointed to ongoing supply chain improvements and continued cost reviews as key to supporting margins.
