Apple CEO Handover From Tim Cook to John Ternus Takes Effect September 1
Tim Cook steps down as Apple’s chief executive on September 1, 2026, handing the role to John Ternus, the company’s senior vice president of hardware engineering, while remaining with the company as executive chairman, according to Apple’s own statement and Reuters.
A Transition Announced Months Ago, Now Reaching Its Effective Date
Apple announced the succession on April 20, 2026. Cook becomes executive chairman on the same date Ternus becomes chief executive and joins Apple’s board.
Market Value Grew More Than 11-Fold Under Cook
“Under Cook’s leadership Apple has grown from a market capitalization of approximately 350 billion dollars to 4 trillion dollars,” representing more than a 1,000 percent increase, Apple said in its statement, adding that yearly revenue nearly quadrupled, from 108 billion dollars in fiscal 2011 to more than 416 billion dollars in fiscal 2025. Apple’s market capitalization stood at about 4.666 trillion dollars as of its August 28, 2026 close, according to CNBC, second among listed companies behind Nvidia, which closed the same day at about 5.24 trillion dollars.
Why it matters: The handover closes out Cook’s 15-year tenure as chief executive, one of the longest and most financially successful in big technology, and hands day-to-day control of one of the world’s most valuable companies to an internal successor rather than an outside hire, a signal of continuity in Apple’s product and engineering strategy.
Outlook: Ternus takes over as chief executive on September 1, with Cook staying on as executive chairman. Markets will watch for any early signals of strategic change once Ternus is formally in the role.
