ATMU

In the past six months, Atmus Filtration Technologies' stock (ATMU) experienced significant fluctuations, reaching a 52-week low of $42.55 on October 8, 2026, after plunging nearly 30%. Key events included a 16.96% drop on May 1, 2026, and a 6.13% decline on August 7, 2026, following its second-quarter 2026 results, despite reporting record sales and adjusted earnings per share that exceeded analyst expectations and raising its full-year adjusted EBITDA guidance. On August 14, 2026, the stock increased by 2.53% after the company raised its quarterly dividend. Insider trading over the past three months showed more sales than purchases, with notable sales by CEO Stephanie Disher and Chief People Officer Renee Swan, and purchases by Director Gretchen R. Haggerty and Chairman Stephen Macadam. The acquisition of Koch Filter earlier in 2026 contributed to strong Q2 sales and improved gross margin. As of October 8, 2026, analysts had a median price target of $67 for ATMU, suggesting potential undervaluation.
