PepsiCo was forced to shrug off a call to break up the business and merge its food operations with Mondelez International again last week as the company issued its first-half results. CEO Indra Nooyi urged the market to "look beyond the noise" surrounding pressure from activist investor Nelson Peltz. Elsewhere, Premier Foods CEO Gavin Darby revealed it was asking suppliers to sign up to "strategic partnership" as part of its plans to cut numbers by half.
