Apple begins a new leadership era as John Ternus succeeds longtime CEO Tim Cook.
Apple enters a new era on September 1 as longtime hardware executive John Ternus officially succeeds Tim Cook, while Cook moves upstairs to become executive chairman.
CUPERTINO, Calif. — For the first time in 15 years, Apple has a new chief executive.
John Ternus officially became CEO of Apple on Tuesday, September 1, 2026, succeeding Tim Cook and beginning one of the most consequential leadership transitions in the technology giant’s history. Cook isn’t leaving Apple altogether. Instead, he is moving into the newly elevated role of executive chairman of the company’s board.
The transition was announced in April after what Apple described as a long-term succession-planning process unanimously approved by its board. Cook remained CEO through the summer while working alongside Ternus to prepare for the handoff.
And now, the handoff is official.
The Tim Cook Era Comes to an End
Cook took over as CEO in August 2011 following Steve Jobs’ resignation, inheriting one of the most closely watched leadership positions in corporate America.
What followed was an extraordinary period of financial expansion.
Apple’s market value grew from roughly $350 billion when Cook took over to more than $4.5 trillion by the time of his departure as CEO, according to Reuters. Under Cook, Apple transformed from a company heavily dependent on hardware sales into an enormous ecosystem built around devices, subscriptions and services.
The Cook era brought products including Apple Watch, AirPods and Vision Pro, while the company dramatically expanded businesses such as Apple Music, Apple TV, iCloud and other services. Apple also made the hugely important transition away from Intel processors in Macs toward its internally designed Apple silicon.
But Cook’s legacy won’t simply be measured in products.
His mastery of Apple’s global supply chain, operational efficiency and relationships with governments helped turn the company into one of the most formidable corporations on Earth.
Cook now moves to executive chairman, where Apple says he will remain involved in certain company matters, including engagement with policymakers around the world.
Who Is John Ternus?
Ternus isn’t an outsider brought in to reinvent Apple.
He’s an Apple veteran.
Ternus joined Apple’s Product Design organization in 2001 and became vice president of Hardware Engineering in 2013. He eventually rose to senior vice president of Hardware Engineering, overseeing engineering for some of Apple’s biggest products.
His résumé includes work across the iPhone, iPad, Mac, Apple Watch and AirPods. He was also a key leader during Apple’s enormously important transition of the Mac to Apple silicon.
That engineering background makes Ternus a particularly interesting choice for Apple’s next chapter.
The company isn’t simply looking for another operator. Apple now needs to prove it can produce its next generation of transformative technology.
Ternus Inherits a Very Different Apple
Ternus may be taking control of one of the world’s most valuable companies, but he isn’t inheriting an easy job.
Artificial intelligence is rapidly reshaping the technology industry.
Apple has faced criticism for moving more slowly in generative AI than competitors, while companies across Silicon Valley are spending enormous amounts of money developing models, infrastructure and AI-powered consumer products.
Reuters describes AI as one of the central challenges facing Apple’s new CEO, alongside reducing Apple’s manufacturing dependence on China as geopolitical tensions continue reshaping global supply chains.
That means Ternus must answer a question that has been building for years:
What is Apple’s next iPhone-sized idea?
Apple has enormous resources, one of the world’s strongest brands and an installed base of devices that gives it an extraordinary distribution advantage.
But size alone doesn’t guarantee technological leadership.
The Hardware Guy Now Runs Everything
Ternus’ promotion also signals something about Apple’s priorities.
He spent decades building products.
Now he gets to decide where those products go next.
The CEO must oversee far more than engineering: services, artificial intelligence, retail, regulatory battles, supply chains, developer relationships, global politics and Wall Street expectations all become part of Ternus’ responsibility.
Cook’s continued presence as executive chairman could therefore be particularly valuable.
Cook can continue helping navigate government and policy relationships while Ternus establishes himself as the company’s public and strategic leader.
It effectively gives Apple something of a bridge between eras rather than an abrupt changing of the guard.
His First Major Test Is Almost Immediate
Ternus won’t have much time to settle into the CEO chair.
Apple’s annual September product event is scheduled for September 9, putting the new chief executive into the global spotlight almost immediately.
It will be his first major product event as CEO and an early opportunity to define what the post-Cook Apple looks and feels like.
That symbolism matters.
Steve Jobs represented Apple’s rebirth and product obsession.
Tim Cook represented Apple’s transformation into an operational, financial and global powerhouse.
John Ternus now has to define the third modern era of Apple.
This With Krish Take
Tim Cook leaves the CEO position with Apple dramatically larger, richer and more powerful than the company he inherited in 2011.
That’s an almost impossible act to follow.
But Ternus doesn’t need to become another Tim Cook — and Apple probably doesn’t need him to.
The technology world has changed.
Artificial intelligence, wearables, spatial computing, robotics and entirely new computing interfaces are opening a race to determine what comes after the smartphone.
Putting a lifelong product and hardware executive in Apple’s top job may tell us exactly where Apple believes its next battle will be fought.
Today isn’t simply the first day of a new CEO.
September 1, 2026 marks the beginning of the post-Tim Cook era at Apple — and potentially the beginning of Apple’s biggest reinvention since the iPhone.
