Azenta's President and CEO John Marotta resigned from the company and its Board effective August 22, 2026, and the Board named director Dr. Martin Madaus as interim President and CEO. The company reaffirmed its fourth quarter fiscal 2026 total revenue guidance but expects a one-time approximately $3 million consulting expense to affect fourth quarter adjusted EBITDA, and a search for a permanent CEO is underway.
