On the earnings call, CEO Howard Schultz noted the company's "flywheel" strategy, which leverages digital, loyalty, and mobile capabilities, and uses Starbucks' brand partnerships to further drive profitability. The extensions Starbucks has made across the high-end beverage market in recent years are unparalleled. While some observers once saw Green Mountain Coffee Roasters ' Keurig single-cup brewing system as a threat to Starbucks' more-expensive cup of Joe, the coffee chain, after initial resistance, partnered with Green Mountain and began producing its own K-cups. It just shipped its one-billionth branded K-cup in the last quarter. Similarly, the company has made a number of acquisitions, including Tazo, Teavana, and Evoultion Fresh, which give it further growth opportunities, and leverage its operational excellence. With its mastery of the coffee market, it only makes sense for Starbucks to set its sights on tea and fresh juice.
