Author’s take: John Ternus inherits a much bigger and richer Apple, but proving the company can compete more strongly in AI may define the start of his tenure.
John Ternus officially became Apple CEO on September 1, 2026, replacing Tim Cook after 15 years at the top of the iPhone maker.
Cook has moved into the role of executive chairman and will continue working with Apple on areas including relationships with policymakers around the world. Apple’s leadership page now lists Ternus as CEO and Cook as executive chair.
Ternus takes control of Apple at a time when the company remains one of the world’s most valuable businesses but faces growing pressure to prove it can keep pace with rivals in artificial intelligence.

Who Is John Ternus?
John Ternus joined Apple’s product design team in 2001 and became vice president of Hardware Engineering in 2013.
He joined Apple’s executive team in 2021 as senior vice president of Hardware Engineering.
During his time at Apple, Ternus helped oversee hardware development across major products including the iPhone, iPad, Mac, Apple Watch and AirPods. Apple also credits him with work involving product reliability, durability, materials and repairability.
Ternus is also now a member of Apple’s board of directors.
What Did Tim Cook Leave Behind?
Ternus takes over a company that became much larger during Cook’s 15 years as CEO.
According to Reuters, Apple’s market value grew from about $350 billion when Cook took over to more than $4.5 trillion.
Annual sales increased from $108 billion to $416 billion, while annual profit grew to $112 billion.
Cook also expanded Apple beyond hardware sales.
Services became a major source of recurring revenue, while products such as Apple Watch and AirPods helped build a large wearables business around the iPhone.
Apple’s wearables business generated about $35 billion in fiscal 2025, according to Reuters.
Why Is AI John Ternus’ Biggest Challenge?
Apple has faced criticism for moving more slowly in AI than companies such as Google, Microsoft and OpenAI.
Reuters reports that investors see AI as Ternus’ biggest challenge, particularly after delays involving improvements to Siri.
Apple has been expanding Apple Intelligence across its devices and introduced a new Siri AI system at WWDC 2026. However, the company still needs to show how AI can become a major part of its products and services rather than simply another feature inside the iPhone.
For Ternus, that means turning Apple’s large hardware ecosystem into an advantage in the AI race.
What Other Challenges Does Ternus Face?
AI is not the only issue waiting for Apple’s new CEO.
The company is also working to reduce its dependence on China for manufacturing.
Apple has expanded production in countries including India and Vietnam as trade tensions, tariffs and supply chain risks have increased.
Reuters reports that Apple plans to make most iPhones destined for the U.S. market in India by the end of 2026. Some AirPods and iPads are also being assembled in Vietnam.
The challenge for Ternus will be continuing that transition without significantly increasing costs or reducing Apple’s profit margins.
Why Does the Apple CEO Change Matter?
Apple’s CEO transition matters because Ternus is taking control during a major shift in the technology industry.
Cook spent much of his tenure improving Apple’s operations, supply chain, services business and global scale.
Ternus now needs to protect those strengths while helping Apple compete in a market increasingly shaped by AI.
His hardware background could be important.
Apple controls both the hardware and software used by hundreds of millions of customers. If the company can combine that ecosystem with more capable AI, it could create experiences that are difficult for competitors to copy.
The risk is that rivals continue moving faster.
What Role Will Tim Cook Have at Apple?
Cook has not left Apple.
As executive chairman, he remains involved with the company and will help with areas including relationships with policymakers around the world.
That could be important as Apple deals with trade tensions, regulation and its changing manufacturing strategy.
Cook’s continued presence also gives Ternus access to an experienced leader during the transition.
What Happens Next for John Ternus?
Ternus will quickly face his first major public test as Apple CEO.
Apple has scheduled a special event for September 9, 2026, at 10 a.m. Pacific Time. In the Philippines, the event begins on September 10 at 1 a.m. PHT.
Reuters expects the event to include Apple’s next iPhone lineup, making it the first major product launch of the Ternus era.
Beyond the launch, investors will be watching for clearer signs of how Ternus plans to strengthen Apple’s AI strategy, grow new product categories and manage the company’s global supply chain.
Those areas are likely to shape how his first years as Apple CEO are judged.
