The departure of Brady Stewart is the latest management change at Tyson Foods, which replaced former Chief Financial Officer John R. Tyson last year following arrests related to drinking. "It's concerning to see yet another senior leader at Tyson Foods involved in a code of conduct violation," said Arun Sundaram, equity analyst at CFRA Research. Tyson Foods named Devin Cole as chief operating officer and said he will oversee its beef, pork, prepared foods, poultry and international business segments. "The company determined certain actions taken by Brady violated the Tyson Foods Code of Conduct," Tyson said in a statement on Tuesday. Tyson Foods suspended former CFO John R. Tyson last year after police in Arkansas arrested and charged him with driving while intoxicated and careless driving.
