John Ternus Named Apple's New CEO, Succeeding Tim Cook After 15-Year Tenure

Apple has named John Ternus as its next chief executive, ending Tim Cook's 15-year run at the top of the world's most valuable consumer technology company. Ternus takes over on September 1, with Cook shifting into the role of executive chairman.

The hardware engineering chief, who has spent 25 years inside the company with his fingerprints on every iPad, AirPods and the Mac's jump to Apple silicon, will take over as chief executive on September 1, ending Tim Cook's 15-year run and one of the most lucrative successions in corporate history.

Ternus, 51, becomes Apple's eighth CEO. Cook, 65, stays on through the summer to manage the handover before moving into the role of executive chairman. The board approved the move unanimously last Friday.

In a staff memo, Cook said now was the right time to step aside and called Ternus a visionary with remarkable integrity. Ternus, in his own note, told employees he plans to stay "very hands-on" in the new job. A town hall at the Steve Jobs Theater is on the schedule.

The identity of Cook's successor was not the surprise. The timing was. Just last month on Good Morning America, Cook publicly shut down retirement talk, saying he loves what he does and could not picture life away from Apple.

Wedbush analyst Dan Ives said the broad Wall Street view was that Cook would hang on for at least another year, and flagged that the announcement lands nine days before Apple's April 30 earnings report.

Cook's record is hard to argue with. Under his watch, Apple's market capitalisation climbed more than tenfold to $4 trillion. Annual revenue went from $108 billion in FY2011 to over $416 billion in FY2025. He shipped the Apple Watch, AirPods and Vision Pro, pulled the Mac onto Apple silicon, and built Services into a $100 billion business on its own.

Ternus steps in at an awkward moment. Apple has been slow on generative AI, delayed its Siri overhaul more than once, and eventually cut a deal with Google to power future Apple Intelligence features using Gemini. Vision Pro never found its audience. The iPhone 17 and iPhone Air have sold well, but there is not much else pulling weight outside the phone.

A mechanical engineer by training, Ternus graduated from the University of Pennsylvania in 1997, briefly worked on VR headsets at Virtual Research Systems, and joined Apple's product design team in 2001.

The reshuffle extends past the corner office. Johny Srouji, Apple's silicon architect, has been promoted to chief hardware officer, absorbing Ternus's old portfolio. Tom Marieb takes over day-to-day hardware engineering and reports to Srouji.

Ternus joins Apple's board on September 1. Arthur Levinson, the company's non-executive chairman for the past 15 years, becomes lead independent director on the same day.
