Tim Cook has completed 15 years as Apple CEO, marking the anniversary just one week before he steps down from the role on September 1, 2026.
Cook became CEO on August 24, 2011, after Steve Jobs resigned and recommended that Apple move forward with its succession plan. Cook had previously served as Apple’s chief operating officer and played a major role in managing the company’s worldwide operations and supply chain.
During Cook’s 15 years as CEO, Apple expanded far beyond the product lineup it had when he took charge. The company introduced major products including Apple Watch, AirPods, HomePod and Apple Vision Pro, while also expanding services such as Apple Music and Apple TV.

Cook also led Apple through years of major financial growth, international expansion and an increasingly large services business. Apple reached the position of the world’s most valuable company multiple times during his tenure.
John Ternus takes over on September 1
Cook’s anniversary arrives just days before Apple begins its next leadership era. John Ternus, currently Apple’s senior vice president of Hardware Engineering, will officially become CEO on September 1. He will also join Apple’s board of directors.
Cook is not leaving Apple completely. He will become executive chairman of the board and will continue helping with certain areas of the company, including engagement with policymakers around the world.
The September 1 transition closes Cook’s 15-year run as CEO while keeping him involved with Apple as Ternus takes charge of the company.
