The coffee giant said its board has approved an authorization to repurchase an additional 25 million common shares. That's on top of the 12.1 million shares left on its previous buyback approval. The news comes hot on the heels of Starbucks announcing a deal to shell out $620 million for Teavana Holdings ( TEA) on Wednesday. Starbucks' shares edged up less than 1% after the close. -- Written by Michael Baron in New York. >To contact the writer of this article, click here: Michael Baron.
