NASHVILLE, Tenn. – Atmus Filtration Technologies Inc. (Atmus; NYSE: ATMU), a global leader in the filtration industry, today announced the appointment of Heath Sharp to its Board of Directors..

“Sharp brings more than 30 years of hands-on leadership across manufacturing, product development and commercial execution, with a career built on scaling industrial businesses internationally,” said Steph Disher, CEO and President of Atmus. “As a seasoned global industrial leader, Sharp joins the Board during a key time when we are well positioned for Atmus’ next phase of growth.”

Sharp currently serves as Chief Executive Officer and Managing Director of Reliance Worldwide Corporation, where he has led the company’s evolution from a regionally focused manufacturer into a global, publicly listed leader in water control systems and plumbing solutions.
