New Apple CEO John Ternus takes over from Tim Cook, ending 15-year tenure

Apple’s new CEO John Ternus takes the helm of the iconic tech giant on Tuesday, ending Tim Cook’s 15-year tenure during which the company’s value skyrocketed to $4.6 trillion thanks to the iPhone’s enormous popularity.

The transition to a new CEO comes at a pivotal time for Apple. Artificial intelligence has unleashed the greatest upheaval within the industry since the late co-founder Steve Jobs unveiled the first iPhone in 2007.

Apple has gotten off to a rough start in AI after stumbling in its efforts to deliver new features built on the technology, as promised nearly two years ago.

Earlier this year, it unveiled new artificial intelligence advances, including upgrades to its Siri assistant, emphasizing a focus on privacy and day-to-day use as the iPhone maker tries to catch up with rivals.

Ternus faces challenges that will force him to step outside his comfort zone in hardware engineering.

Beyond finding ways to keep Apple competitive in the artificial intelligence race, he will need to navigate supply chain questions and relationships with figures such as President Trump, who has offered public praise for his predecessor.

Serving as Apple CEO will also require soft skills, including developing relationships with important figures. Cook cultivated ties with Trump as he navigated the company through business challenges, including the president’s trade and tariff war targeting countries in Asia, where Apple has extensive manufacturing supply chains.

Although he is handing over the CEO reins at Apple, Cook is widely expected to help the company maintain a good relationship with the Trump administration after he shifts to his new role as executive chairman.

Ternus worked on some of Apple’s signature products under Cook, including the Apple Watch, AirPods and Apple Vision Pro. He will headline next week’s launch of the latest iPhone at Apple’s Cupertino, Calif., headquarters.
