John Ternus Becomes Apple CEO as Tim Cook Steps Aside After 15 Years
On this page
John Ternus became the chief executive officer of Apple on September 1, 2026, ending Tim Cook’s 15-year run at the top and handing the company to a hardware engineer for the first time since Steve Jobs. Cook moves into an executive chairman role focused on policy and government relations, while Arthur Levinson, Apple’s chairman for the past 15 years, steps back to lead independent director. The board approved the plan unanimously back in April, and the handoff landed eight days before Ternus is due to walk on stage for his first keynote.
I have watched Apple keynotes since the aluminium unibody MacBook, and I did not expect the succession to feel this quiet. There was no shock resignation, no activist campaign, no boardroom leak. Apple told everyone in April exactly what would happen and when, then did it. That calm is the story as much as the name on the door.
What actually changed on September 1
Three titles moved at once. Ternus, previously senior vice president of Hardware Engineering, is now CEO and joins the board. Cook, who ran Apple from 2011, is executive chairman and will spend his time with regulators and heads of state, the part of the job that has swallowed more and more of a modern Apple CEO’s calendar. Levinson, a fixture on the board since 2000 and chairman since 2011, becomes lead independent director.
Apple also reshuffled the engineering bench. Johny Srouji, who built Apple’s custom silicon group into one of the most valuable teams in the industry, takes over the broader hardware engineering organisation that Ternus used to run. Laura Legros, a former Apple engineering vice president, came out of retirement at Ternus’s request to help run the CEO’s office. None of that is dramatic on its own, but together it signals that Ternus wants his own people close.
Who John Ternus is
Ternus is not a finance executive or a marketer. He is a mechanical engineer with a degree from the University of Pennsylvania who worked at Virtual Research Systems, a small VR headset maker, before joining Apple’s product design team in 2001. He spent the Jobs years inside the labs, became a vice president of hardware engineering in 2013, and was promoted to senior vice president in 2021. Along the way he owned the engineering for the iPad, AirPods, several iPhone generations, the Mac’s move to Apple silicon, and the Apple Watch.
If you have watched an Apple event in the last five years, you have seen him. Ternus is the executive Apple sends out to explain the M-series chips and the iPhone Pro cameras, calm and specific, never oversold. Gene Munster of Deepwater Asset Management summed up the market’s read in a single line to CNBC: “They went with a product person, and I think that’s important.”

Why now, and why him
Cook is 65, the age at which Apple has historically expected executives to think about stepping back, and he had run the company for a decade and a half. Reporting through late 2025 and early 2026 pointed to Ternus as the front-runner well before the April announcement, in part because Apple’s next decade of problems are hardware and engineering problems: on-device AI silicon, a foldable iPhone, smart glasses, health sensors, and a supply chain being pulled in three directions by tariffs and component shortages.
Memory pricing is a live example. A global scramble for AI server memory has pushed DRAM and NAND costs up sharply, and every iPhone, iPad, and Mac ships with both. That is now Ternus’s margin problem to manage. Apple’s chip partnerships, including its extended custom-silicon deal with Broadcom, and its push toward on-device AI hardware like the M6 Mac mini, are the kind of decisions that now cross his desk first.
The Siri problem he inherits
The most visible weakness is software, not hardware. Apple promised a rebuilt, more capable Siri in 2024, delayed it into 2026, and has watched Google and OpenAI set the pace on assistants and agents. Ternus has never run software, and Apple’s AI and services leadership is not in his engineering comfort zone. Analysts who follow the stock, including Bank of America’s Wamsi Mohan, who kept a buy rating and a $380 price target through the transition, have been clear that a credible AI roadmap is the bar Ternus has to clear in his first year.
His first memo to staff leaned on the thing he knows best. “We have a huge launch next week that’s going to be phenomenal,” he wrote, pointing at the September 9 event where Apple is expected to show the iPhone 18 Pro line, a thinner iPhone, its first foldable, new Apple Watches, and, finally, more of the delayed Siri work.
What to watch next
The September 9 keynote is the first real test. Beyond the product reveals, watch how Ternus handles the parts of the job Cook made his own: the China relationship, the European Union’s Digital Markets Act enforcement, and US trade policy. Cook staying on as executive chairman gives Apple a bridge for exactly those conversations, but the market will want to see Ternus own them within a year. For now, investors seem content. The stock went up, the analysts stayed positive, and Apple pulled off a once-in-a-generation change without a single surprise.
Frequently asked questions
Is Tim Cook leaving Apple entirely?
No. Cook is now executive chairman of Apple’s board, an active role focused on government and policy engagement, mentoring Ternus, and representing Apple externally. He is not retiring from the company.
Why did Apple choose John Ternus over a software or services executive?
Ternus spent 25 years running hardware engineering across nearly every Apple product line and is seen internally as a product-first leader in the Jobs mould. Apple’s board and outside analysts framed the next decade of challenges, custom silicon, AI hardware, foldables, and supply chain, as engineering-led, which favoured him.
When is John Ternus’s first Apple keynote as CEO?
Apple’s fall event is scheduled for September 9, 2026, where Ternus is expected to introduce the iPhone 18 Pro lineup, a new thinner iPhone, Apple’s first foldable iPhone, updated Apple Watches, and additional AI and Siri features.
How did Apple stock react to the CEO change?
Apple shares rose roughly 2.5% on September 1, 2026, the day the transition took effect. Analysts largely kept positive ratings, viewing the long-planned, drama-free handoff as a sign of institutional stability.
What is the biggest challenge facing the new CEO?
A credible artificial intelligence strategy. Apple’s promised Siri overhaul has slipped repeatedly, and rivals have moved faster on assistants and agents. Rising memory and component costs and trade policy are the other near-term pressures.
