Activist Elliott Management is calling for a shakeup at Goodyear Tire & Rubber (NASDAQ: GT), including recommending five candidates for the company’s board. Elliott Management, the hedge fund run by billionaire Paul Singer, has a long track record of successfully pushing for change inside companies. In a letter to Goodyear’s board released Thursday, the fund spotlighted a low operating margin, an underutilized retail platform, and a loss of investor confidence as reason change is needed.
