Starbucks Corp. announced a long-term strategic plan Tuesday afternoon that includes shipping more cash back to investors while closing down underperforming stores in certain markets. The announcement, which was made just before being discussed at an Oppenheimer conference in Boston, said that the plan was developed with goals of accelerating growth in the U.S. and China while “sharpening the focus on increasing shareholder returns.” “While certain demand headwinds are transitory, and some of our cost increases are appropriate investments for the future, our recent performance does not reflect the potential of our exceptional brand and is not acceptable,” Chief Executive Kevin Johnson said. “We must move faster to address the more rapidly changing preferences and needs of our customers.” Starbucks said it plans to close about 150 company-operated stores “in its most densely penetrated markets,” up from an average of 50 annually, while looking to open stores in other markets. Overall, the rate of store growth would slow, the company said. Starbucks hiked its dividend 20%, to a quarterly return of 36 cents a share, and said it plans to return $25 billion to shareholders in dividends and buybacks through its 2020 fiscal year. Starbucks also said it now anticipates 1% same-store sales growth in the current quarter. Starbucks stock declined by almost 3% in late trading; shares have been flat so far in 2019, as the S&P 500 index has gained 3.8%.
