The story at Tyson Foods is an ever-changing saga as the meat giant continues its metamorphosis away from commodity-based business models to more consumer-branded and higher-margin products following the $8.55 billion acquisition of Hillshire Brands in August 2014. At Tyson Foods' presentation at the Consumer Analyst Group of Europe annual conference in London on Wednesday , executives told analysts that Tyson's branded product portfolio, operational execution and other improvements from the acquisition of Hillshire Brands give them the confidence to reiterate fiscal 2015 guidance of $3.30 to $3.40 adjusted earnings per share.
