"Our success for shareholders is the byproduct of our commitment to long-term decision making and operating in the interest of all stakeholders, including guests, associates, and franchisees," Panera Bread founder Ron Shaich said in a statement. "We believe this transaction with JAB offers the best way to continue to operate with this approach.
