TL;DR
John Ternus became Apple’s CEO on September 1, 2026, replacing Tim Cook after 15 years. Cook stays on as executive chairman, handling government relations. Ternus, 50, joined Apple in 2001, ran hardware engineering since 2021 and led the Apple silicon transition. Cook grew Apple from under $350 billion to $4.6 trillion, with revenue up from $108 billion to over $400 billion, but leaves Apple trailing in AI. Ternus debuts at the September 9 iPhone event.
Apple changed chief executives on a Tuesday, with almost no drama, eight days before the biggest hardware launch on its calendar. Tim Cook handed the company to John Ternus on September 1, 2026, ending a run that began when he took over from Steve Jobs on August 24, 2011. The handover had been telegraphed for months. The scale of what Ternus is picking up has not sunk in for most people.
A succession that surprised nobody
Apple made the announcement in April. The board approved the transition unanimously, and Cook stayed in the CEO chair through the summer to work with Ternus on the handoff. Cook remains at the company as executive chairman, Ternus joins the board of directors, and Arthur Levinson, non-executive chairman for the past 15 years, becomes lead independent director. Per 9to5Mac, Bloomberg has reported that Cook’s focus as chairman will be Apple’s relationships with the Trump administration and the Chinese government. That is not a ceremonial retirement. It is a division of labour, with Cook keeping the two files that have historically been the riskiest for Apple’s supply chain and its politics.
Who is John Ternus?
Ternus is 50, and he has spent almost his entire working life inside Apple. He joined in 2001 on the product design team and was promoted to senior vice president of Hardware Engineering in January 2021, taking over from Dan Riccio. He graduated from the University of Pennsylvania in 1997 with a degree in mechanical engineering and applied mechanics and a minor in psychology, and swam competitively there.
His fingerprints are on most of what Apple currently sells. He has worked across the iPad, AirPods and Apple Watch lines, and Fortune notes he has overseen hardware engineering for virtually every major product in the current portfolio. He also helped lead the move off Intel chips to Apple’s own silicon, and is described internally as calm, detail-obsessed and deeply familiar with the supply chain. In his statement, Ternus said he had been lucky to work under Steve Jobs and to have had Cook as his mentor.
The signal here matters. Apple has handed the company to a product engineer rather than an operator, which is a different bet than the one the board made in 2011.
Cook’s record, by the numbers
Apple’s shares are up 2,275% since Cook took over. He inherited a company worth less than $350 billion and leaves behind a $4.6 trillion business. Apple briefly touched $5 trillion on July 28, 2026, reclaiming the title of the world’s most valuable company.
Revenue tells the same story. Fiscal 2025 revenue reached $416.2 billion, up from $108 billion in fiscal 2011, and Bloomberg reporting puts fiscal 2026 on track for roughly $477 billion. Services, the quiet engine of the Cook era, grew from $16 billion in fiscal 2013 to more than $109 billion in fiscal 2025. Buybacks topped $840 billion since fiscal 2012 and cut the share count by nearly 45%. Bank of America’s Wamsi Mohan put it starkly: Apple created market value at about $32 million an hour, every hour, for close to 15 years. Cook was also the first openly gay CEO of a Fortune 500 company.
Where the record gets thinner
The criticism has always been the same one. Cook’s Apple did not launch a genuinely new product category on the scale of the iPhone, and Siri fell badly behind as the AI era arrived. Apple Intelligence shipped useful writing and image features, but the more personal version of Siri took far longer than users expected, and by 2026 Apple was leaning partly on licensed Gemini technology for its next assistant. That is an awkward position for a company built on controlling its own stack. Investors noticed: the market cap has slipped from around $5 trillion to roughly $4.5 trillion after the last earnings report.
What Ternus inherits
Ternus, not Cook, is expected on stage at the September 9 event, where Apple is tipped to show its first foldable iPhone. The harder question sits behind the hardware. Mohan expects Apple’s risk appetite to change under Ternus, with more spending on R&D, capital expenditure and acquisitions, none of which was emphasized in the Cook years.
Cook made Apple the most profitable consumer hardware business in history by being patient, disciplined and late to almost everything. Ternus does not get to be late this time.
