Soft drinks and snack food producer PepsiCo saw its net income grow 13% to US$777m for the first quarter, with earnings per share for the period up 17% to US$0.45. The company was boosted by a reduction in costs relating to the Quaker merger. But carbonated soft drink volume in the key North America region fell 2%, dragged down by declines in the Pepsi and Mountain Dew brands.
