Shares of Atmus Filtration Technologies Inc. (NYSE: ATMU) surged 6.52% in pre-market trading on Friday, following the company's announcement of better-than-expected second-quarter results and an improved outlook for 2025. The filtration solutions provider's strong performance and optimistic guidance have sparked investor enthusiasm, driving the stock's significant uptick.

Atmus reported impressive Q2 2025 results, with net sales reaching $454 million, a 4.8% increase from the same period last year and surpassing analyst estimates of $432.8 million. The company's adjusted earnings per share came in at $0.75, beating the consensus expectation of $0.65 and showing improvement from $0.71 in the previous year. Atmus attributed its robust performance to higher volume and pricing increases, partially offset by unfavorable currency impacts.

Adding to the positive sentiment, Atmus raised its guidance for the full year 2025. The company now expects revenue between $1.685 billion and $1.735 billion, up from its previous forecast of $1.67 billion to $1.74 billion. Additionally, Atmus projects adjusted earnings per share in the range of $2.40 to $2.60, compared to its earlier outlook of $2.35 to $2.60. This improved guidance reflects the company's confidence in its business model and growth prospects, despite challenges such as unfavorable logistics costs and one-time separation costs from Cummins Inc. The company's ability to navigate these headwinds while delivering strong results has clearly resonated with investors, as evidenced by the stock's pre-market surge.
