Azenta's president and chief executive, John Marotta, resigned on August 22, 2026, also giving up his board seat, with the filing stressing that there was no disagreement with the company over operations, policies or practices. The same day, the board appointed Dr. Martin Madaus — an Azenta director since January 2024 who chairs its nominating and governance committee — as interim President and CEO, and he now serves as the company's principal executive officer for SEC reporting purposes. With Marotta gone, the board shrank from nine members to eight, and Azenta says it expects to add to Madaus' compensation to match his expanded duties.
