Last month, Hurd went on a medical leave for unspecified health reasons, while Catz and founder Larry Ellison took over his responsibilities during the absence. “Oracle has lost a brilliant and beloved leader who personally touched the lives of so many of us during his decade at Oracle,” Ellison wrote in an email to company employees. Hurd and Catz were named co-CEOs in 2014, after Ellison decided to step aside to focus on his role as chief technology officer.
