Starbucks delivered record results during the festive period, as consumers maintained their coffee habit despite the tough economic conditions affecting many economies. In the first quarter ended 2 January 2011, Starbucks saw revenue climb 8% to a record $3bn (£1.9bn). This was driven by a 7% jump in store sales, with an increase in people grabbing a coffee at a Starbucks in the period rather than higher pricing. First quarter operating income leapt 42% leapt to $501.9m ($352.6m). Howard Schultz, chief executive of Starbucks, said: "Our holiday lineup, bolstered by Christmas Blend and Starbucks Christmas VIA along with the world-class service of our partners, resonated well with customers and led to record results for the quarter. "The strength in our top line - combined with continued improvement in operations - continues a recent trend of record quarterly operating profits and margins, enabling us to more than offset the impact of unusually high coffee costs." Starbucks celebrates its 40th anniversary in March. It plans to open 500 stores in its current financial year, including 100 in the US.
