SAN FRANCISCO — One of the most consequential leadership transitions in modern tech history is set to unfold at Apple this year: long-serving chief executive Tim Cook will step down from his top role this September, passing the reins to 22-year company veteran John Ternus as the Silicon Valley giant navigates a rapidly shifting global technology landscape reshaped by the artificial intelligence boom.
The 65-year-old Cook, who has steered Apple for 15 years after taking over from the company’s iconic co-founder Steve Jobs following Jobs’ health departure in 2011, will transition into the role of executive chairman of Apple’s board of directors after his exit from the CEO post. The long-awaited announcement, made public this Monday, puts to rest years of market and industry speculation about who would inherit the leadership of the world’s most valuable company.
Cook first joined Apple back in 1998, working his way up through the executive ranks to become chief operating officer, where he oversaw the iPhone maker’s famously complex global supply chain and laid the operational groundwork for Apple’s explosive growth in the 2000s. When he stepped into the CEO role in 2011, Cook inherited a company at the peak of its early success, and over his 15-year tenure, he delivered transformative growth: he expanded Apple’s product portfolio far beyond its core iPhone line, and guided the company to a staggering market valuation of roughly $4 trillion in current share price terms.
“It has been the greatest privilege of my life to be the CEO of Apple and to have been trusted to lead such an extraordinary company,” Cook said in an official statement announcing the transition.
Arthur Levinson, Apple’s outgoing board chairman, lauded Cook’s unprecedented tenure at the company’s helm, noting that “Tim’s unprecedented and outstanding leadership has transformed Apple into the world’s best company. His integrity and values are infused into everything Apple does.”
Ternus, the incoming CEO, first joined Apple’s product design team back in 2001, working his way up to senior vice president of hardware engineering over the course of more than two decades at the company. He has been a core contributor to nearly all of Apple’s flagship product launches over that period, playing key roles in the development of iPhones, iPads, Apple Watch, and the modern line of Mac personal computers.
For Ternus, the opportunity to lead Apple comes after a career shaped by the company’s two most recent leaders: “Having spent almost my entire career at Apple, I have been lucky to have worked under Steve Jobs and to have had Tim Cook as my mentor,” he said in the official announcement.
The leadership transition comes at a pivotal moment for Apple, as the global tech industry races to integrate generative artificial intelligence into consumer products and services, putting new competitive pressure on established players to innovate or risk falling behind to faster-moving rivals. Ternus’ deep background in hardware development also signals that Apple will continue to tie its AI innovation to its core integrated product ecosystem, a strategy that has defined the company’s success for decades.
