Apple CEO Tim Cook is stepping down as Apple's chief executive officer, and hardware engineering chief John Ternus is set to take over, Apple announced today.

Cook will continue on as Apple CEO through the summer, with Ternus set to join Apple's Board of Directors and take over as CEO on September 1, 2026. Cook is going to transition to executive chairman, and he will "assist with certain aspects of the company, including engaging with policymakers around the world."

In a statement, Cook said that his time as Apple's CEO has been the "greatest privilege" of his life.

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. 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. John Ternus has the mind of an engineer, the soul of an innovator, and the heart to lead with integrity and with honor. He is a visionary whose contributions to Apple over 25 years are already too numerous to count, and he is without question the right person to lead Apple into the future. I could not be more confident in his abilities and his character, and I look forward to working closely with him on this transition and in my new role as executive chairman.

Ternus said that he is optimistic about what Apple can achieve in the years to come.

I am profoundly grateful for this opportunity to carry Apple's mission forward. Having spent almost my entire career at Apple, I have been lucky to have worked under Steve Jobs and to have had Tim Cook as my mentor. It has been a privilege to help shape the products and experiences that have changed so much of how we interact with the world and with one another. I am filled with optimism about what we can achieve in the years to come, and I am so happy to know that the most talented people on earth are here at Apple, determined to be part of something bigger than any one of us. I am humbled to step into this role, and I promise to lead with the values and vision that have come to define this special place for half a century.

Apple says that the transition was approved by the Board of Directors and is the result of a "thoughtful, long-term succession planning process." The current board chair, Arthur Levinson, will become the lead independent director on the board.
