With food prices expected to rise again this year, aggressive companies in the sector are looking for smaller businesses to gobble up, and thereby take a bigger bite out of your paycheck. Hillshire Brands Co. (HSH) is one of those aggressive sorts and is about to devour Pinnacle Foods Inc. for about $6.6 billion. Once purchased, Pinnacle???s product line will add Duncan Hines baking mixes and Vlasic pickles to Hillshire???s line of breakfast-meat products. HSH will pay about $18 per share (plus a half-share of Hillshire stock) for each share of Pinnacle. In the end, HSH ends up paying a 20% premium for Pinnacle shares. And investors now have the chance to add cake and pickles to their breakfast menus.
