Tim Cook, the CEO of Apple Inc. (NASDAQ:AAPL), will step down on September 1, 2026, transitioning to the role of executive chairman. This announcement ends years of speculation regarding his retirement. Cook has led Apple since August 2011, during which time the company's market capitalization soared from approximately $350 billion to $4 trillion, and annual revenues quadrupled from $108 billion to over $416 billion. His leadership saw the launch of groundbreaking products such as the Apple Watch, AirPods, and Apple Vision Pro, while also expanding Apple's services business into a $100 billion entity. John Ternus, a 25-year veteran at Apple and previously overseeing the design team, has been named as Cook's successor. Analysts express mixed feelings about Ternus's upcoming leadership, particularly regarding Apple's position in the competitive AI landscape, as the company undergoes significant transitions in this area. Cook will remain active in guiding Apple as executive chairman, particularly on government and policy issues.
