A new era officially began at Apple this week as John Ternus stepped into the role of chief executive officer, taking over from Tim Cook after fifteen years at the helm of one of the most valuable companies in the world. The transition, effective September 1, was the result of a long-planned succession process that Apple's board approved unanimously back in April, giving both Cook and Ternus months to work closely together before the formal handoff. Cook now moves into the role of executive chairman, a position that will keep him involved in select responsibilities, including engaging with policymakers around the world, while stepping back from day-to-day leadership of the company. Under Cook's tenure, Apple's value climbed from roughly $350 billion to as much as $4.6 trillion at its peak, a staggering transformation that will make him an extraordinarily difficult act to follow.

Ternus is far from an outsider walking into unfamiliar territory. He joined Apple's product design team back in 2001, spent 25 years climbing through the ranks, and most recently served as senior vice president of hardware engineering, a role in which he oversaw the development of some of the company's most recognizable products, including the iPhone, iPad, Mac, Apple Watch, and Vision Pro. His deep technical background in hardware, rather than software or services, has led analysts to interpret his appointment as a signal that Apple intends to double down on product innovation as it works to keep pace with rivals in artificial intelligence. As part of the same leadership shakeup, Johnny Srouji has taken over hardware technologies as chief hardware officer, while other executives have shifted responsibilities across design, services, and AI, reflecting a broader reshuffling that has been building inside Apple for nearly two years.

The timing of this handover could hardly be more consequential. Ternus takes the reins just days before Apple's September 9 product event, where the company is widely expected to unveil its first-ever foldable iPhone, a device that would mark one of Apple's biggest hardware departures in years. According to Bloomberg's Mark Gurman, who has closely tracked the device's development, the foldable iPhone could carry a price tag exceeding $2,000, positioning it as one of the most expensive phones Apple has ever released. That launch will effectively serve as Ternus's first major public test as CEO, putting his hardware engineering background directly in the spotlight at a moment when investors and consumers alike will be watching closely for signs of how he plans to lead differently than Cook did.

Beyond the foldable phone, Ternus inherits a company navigating serious headwinds, particularly around artificial intelligence, an area where Apple has faced growing pressure to catch up to competitors who moved faster in recent years. Investors appeared cautiously optimistic about the change, with Apple's stock rising modestly on the day Ternus officially took over, continuing a run that has seen shares climb more than sixteen percent since the start of 2026. Cook is expected to remain a steady presence behind the scenes, particularly in maintaining the company's relationship with the Trump administration amid ongoing trade and tariff tensions affecting Apple's manufacturing operations across Asia. For now, all eyes turn to September 9, where Ternus will step out from behind the hardware division he built his career on and into the far more visible role of steering Apple's next chapter.
