US chewing gum manufacturer Wrigley has reported third-quarter net income of US$98.5m, or 44 cents a share, up 8% from last year's third-quarter earnings of $91.5m, or 41 cents a share. The company's profits for the period ending 30 September were at the low end of analysts' expectations due to expensive advertising and costs incurred during Wrigley's failed bid for US confectioner Hershey Foods.
