Dublin-based Medtronic plc reported the retirement of CEO Omar Ishrak effective April 26, 2020. In a move that may lead to further changes at the company, the board named Geoff Martha, currently executive vice president of Medtronic's restorative therapies group, Ishrak's successor. Martha edged out the previous frontrunner for the job, Mike Coyle, who heads Medtronic's cardiac and vascular group, the company's largest division.
