Cook has been Apple's CEO since 2011Tomorrow, Apple's hardware engineering chief John Ternus will become the company's next CEO. Cook will remain at Apple as the executive chairman of the company's board of directors. In this new role, Apple said Cook will assist with "certain aspects" of the company, including "engaging with policymakers around the world."

Cook became Apple's CEO in August 2011, after Steve Jobs stepped down due to health problems. Under his leadership, Apple became the world's most valuable company on multiple occasions, and it launched products and services such as the Apple Watch, AirPods, HomePod, Vision Pro, Apple Music, Apple TV, and much more.

"It has been the greatest privilege of my life to be the CEO of Apple and to have been trusted to lead such an extraordinary company," said Cook. "I love Apple with all of my being, and I am so grateful to have had the opportunity to work with a team of such ingenious, innovative, creative, and deeply caring people who have been unwavering in their dedication to enriching the lives of our customers and creating the best products and services in the world."
