John Ternus will take over as Apple’s chief executive in September at a moment of unusual strain for the Silicon Valley giant, as it battles doubts over its position in AI and confronts a more fragile global supply chain.
The 50-year-old hardware engineer, a 25-year veteran of the iPhone maker, has quietly attached his name to some of Apple’s biggest bets over the past decade.
But for investors and employees, the transition will test whether the company’s business — built on hardware prowess and operational discipline — can adapt to an industry being reshaped by generative AI.
Apple has been slower than rivals to roll out breakthrough AI features, raising questions about whether its next CEO must redefine rather than extend the strategy that made it a $4tn giant.
“The question is whether he has the appetite for the kind of bold, occasionally uncomfortable decisions that defining a new platform requires,” wrote the IDC’s Francisco Jeronimo. “Building an AI platform that developers and enterprises genuinely adopt is a different challenge.”
Colleagues describe a quiet, unassuming figure who has built a reputation for competence as his responsibilities have grown.
“He’s kind of a dad . . . just a nice guy,” said one former Apple executive. “He’s interestingly enough one of the ‘old guard’, but at the same time still quite young.”
Under Ternus’s oversight as hardware chief, Apple has experimented with new devices to expand beyond the iPhone, while pushing out models that depart from its typical annual cycle.
He has been the face of those changes, including Apple’s “skinny” iPhone Air, launched late last year, and the MacBook Neo, the company’s entry into the affordable laptop space, which was unveiled last month.
Not all of these have been resounding successes. The iPhone Air, which marked the biggest design shake-up for the iPhone in years, proved a relative commercial flop. The Vision Pro headset, which Ternus also oversaw, reported disappointing sales.
But one former colleague said Ternus’s technical skills would allow him to distinguish himself from his two predecessors, “from Steve Jobs’ focus on product storytelling and marketing, to Tim Cook’s operational excellence . . . and now a leadership bench that is deeply rooted in engineering”.
Cook has long said that his successor should come from within the company. His closest lieutenant, Jeff Williams, left Apple in November and later joined Disney’s board, removing him from the running.
Ternus then beat other top Apple executives who are more recognisable, including software head Craig Federighi and marketing chief Greg ‘Joz’ Joswiak.
“This company will reach such incredible heights under [Ternus’s] leadership,” Cook wrote to employees on Monday. “I can’t wait for you to get to know him like I do.”
“For a time, it might have been Craig Federighi as successor, but in my opinion, he fumbled the bag on AI and Siri,” said one former colleague. “He’s also closer to retirement” at 56, they added.
“I’m bullish on John as a leader,” said another Apple staffer. “Choosing an insider is another example of Apple realising they don’t do well integrating outsider execs into their unique culture . . . I think he was the best internal candidate.”
Cook and the board, meanwhile, paved the way for Ternus by introducing a new generation of talent at the top of the company over the past year. These include chief financial officer Kevan Parekh, operations chief Sabih Khan, legal general counsel Jennifer Newstead and AI chief Amar Subramanya.
A California native, Ternus is intensely private about his personal life. He joined Apple in 2001 a few years after graduating from the University of Pennsylvania with a degree in mechanical engineering.
His first 15 years at Apple were spent largely in the shadows. It was only in 2017 that he made his debut at Apple’s annual developer conference, a badge of honour for rising stars.
Colleagues said it was his prominent role in Apple’s pivot from Intel’s PC chips towards in-house chips around 2020 that cemented his status as a leading figure at the company. The iPhone maker bet its own silicon engineers could build competitive chips against an industry behemoth while shifting to a new underlying architecture.
It paid off, cutting outsourcing costs and giving it complete control of its hardware. Ternus later spoke of the shift as “one of the most, if not the most profound change at Apple, certainly in our products over the last 20 years”.
In another signal of business as usual, Johny Srouji, who as the company’s longtime top silicon engineer worked closely with Ternus to execute on that strategy, was promoted to chief hardware officer on Monday.
Late last year, Ternus was also given oversight of the company’s software design teams, just as the company prepares to unveil a revamp to its Siri voice assistant, seen as crucial to demonstrating it can lead in AI.
“If we’re doing it right, people won’t necessarily even notice or think about it,” Ternus said of Apple’s AI strategy in March. “They will just have a new feature that they start using more and more because they really like it.”
Still, analysts are fretting over Apple’s failure to keep up with its competitors in developing new AI software that can overhaul its products and help defend its dominant position in personal devices.
“The new Siri needs to go off without a hitch and be something that people want to use,” said Gene Munster at Deepwater Asset Management.
“Then he needs to start to bring in some outside talent, people from AI-first companies . . . culturally they need to show the rank and file that they are reinventing themselves.”
