Michael Conway, the CEO of Starbucks North America, has announced his retirement after only five months in the position. This leadership change comes amid a broader strategic overhaul at the company, as new CEO Brian Niccol aims to revitalize the brand. Starbucks is currently searching for a global brand czar to guide future initiatives following this significant departure. Conway's resignation marks another major shift in the company's leadership, which has seen various executives leave in recent months.
