Starbucks has closed over 400 underperforming stores across the US as part of a $1 billion restructuring plan. The company aims to remodel and open new locations with updated designs and customer experiences by 2026. Despite mixed financial results for the last fiscal year, including a revenue increase but a drop in earnings per share, Starbucks reported global comparable store sales growth for the first time in seven quarters, indicating early progress in its turnaround strategy.
