Starbucks Coffee has reported an increase in its net revenues by 11% with earnings of $3.4bn for the fourth quarter (Q4) ended 30 September 2012, up from $3bn during the same period last year.

The increase in net revenues was primarily due to 6% increase in global comparable stores sales, 32% revenue growth in channel development and 14% revenue growth in licensed stores, where the 6% increase in comparable store sales was driven by 5% increase in the number of transactions and 1% increase in average ticket.

Operating income during the latest three months period grew by 16% from $448.3m in 2011 to $519.6m in 2012.

Starbucks CEO, president and chairman Howard Schultz said their Q4 and overall 2012 fiscal year performance demonstrates the strength of their business and brand.

"The resiliency and relevance of our U.S. retail business, acceleration of the Channel Development business and expansion in Asia all contributed significantly to our strong results," Schultz added.

Starbucks chief financial officer Troy Alstead said by delivering relevant innovation to their customers while increasing focus on execution and operating efficiencies, they drove sales growth and expanded profit margins.

"On the strength of our business in fiscal 2012 and the momentum we carry into the new fiscal year, we remain confident in our fiscal 2013 outlook of continued strong profitable growth on a global scale," Alstead added.
