PepsiCo, the soft drinks and snack manufacturer, has reported a 61% increase in fourth quarter profits to $1.78bn (£908m) for the three months to 30 December 2006, compared to the previous year. Revenue climbed 3% to $10.38bn. However, shares in the company fell by 1.8% as analysts voiced concerns over the higher costs the company was incurring for raw materials such as orange juice, corn, cooking oil and sugar plus recent sales declines for its Gatorade and Tropicana products. For the full year, PepsiCo said that profit rose 38% to $5.64bn, while revenue rose 7.9% to $35.14bn.
