Dr. Stephen Hahn is a physician-scientist and executive leader with over two decades of experience spanning oncology, federal regulation, and biotechnology. He previously served as the 24th Commissioner of Food and Drugs at the U.S. FDA, overseeing regulatory activities across therapeutics, vaccines, medical devices, and diagnostics. He subsequently led Harbinger Health, a Flagship Pioneering company focused on early cancer detection. A radiation oncologist by training, Dr. Hahn served in senior leadership roles at MD Anderson Cancer Center and the University of Pennsylvania and has authored more than 220 peer-reviewed publications. He currently serves as CEO and Board Chair of Nucleus RadioPharma. “We are grateful for the remarkable contributions of Sybille van den Hove and Muriel de Lathouwer, whose vision and commitment have been a true asset to IBA”, concludes Pierre Mottet, Chair of Board of Directors. “We are especially grateful to Sybille for her contribution to IBA’s sustainability journey and B Corp achievements. We are equally delighted to welcome Joyce Hansen and Steve Hahn to our Board. Their complementary expertise in sterilization science, oncology, and regulatory affairs will be a tremendous addition as IBA continues to advance its mission of improving patient outcomes worldwide.” Dividend distribution The Board approved the payment of a gross dividend of €0.25 per share for the financial year 2025, payable on July 1st. ***ENDS*** About IBA IBA (Ion Beam Applications S.A.) is the world leader in particle accelerator technology.
