Sales for the quarter rose 7.4% to $16.9 billion in the quarter ended Aug. 31, the company said in a statement. Comparable store sales, not including Duane Reade stores, rose 1.5%.
"The double-digit increase in fourth quarter earnings per share was driven by strong operating performance across our 7,500-store network and expense control companywide," said Walgreens CEO Greg Wasson.
For fiscal 2010, net earnings per share rose 5% to $2.12 per share. Sales were $67.4 billion.
The company also completed its $2 billion share repurchase program in the quarter.
