Atmus Filtration Technologies’ first quarter was marked by a year-on-year sales increase driven largely by its acquisition of Cook Filter and modest price gains, but the market reacted negatively to the results. Management identified integration progress, positive initial performance from the new Industrial Solutions segment, and ongoing supply chain improvements as key contributors. CEO Stephanie Disher highlighted challenges related to the Middle East conflict, which resulted in a temporary sales impact, as well as muted aftermarket demand and destocking trends in certain regions. Disher acknowledged, “The Middle East impacted our ability to deliver to our customers in the month of March…that was a 1% impact that we are not expecting to continue.”
