After a 15-year tenure, Tim Cook will transition to executive chairman as hardware chief John Ternus takes over as CEO from 1 September, marking a significant leadership shift at Apple
Global tech giant, Apple is set for a leadership transition as Chief Executive Officer Tim Cook steps down after 15 years, with hardware chief John Ternus taking charge from 1 September. Cook will move into the role of executive chairman, marking the end of a tenure that expanded the company into a USD 4 trillion technology giant with a diversified portfolio.
Ternus, 50, currently heads hardware engineering and has spent nearly 25 years in product development at the iPhone maker. His elevation formalises a succession plan that had long been anticipated within the company.
Leadership Transition
As part of the restructuring, Ternus’s existing responsibilities will be transferred to deputy Tom Marieb, who will report to Chief Hardware Officer Johny Srouji. Srouji will oversee an integrated division combining hardware engineering with hardware technologies, signalling a more unified product development structure.
Ternus assumes leadership at a time when Apple faces increasing pressure to strengthen its capabilities in artificial intelligence, an area where rivals have moved ahead despite the company’s steady financial performance.
“John Ternus has the mind of an engineer, the soul of an innovator, and the heart to lead with integrity and with honor,” said Apple Inc. Chief Executive Officer Tim Cook. “He is a visionary whose contributions to Apple over 25 years are already too numerous to count, and he is without question the right person to lead Apple into the future.”
Strategic Shift
Cook, who will now focus on engaging with global policymakers, already manages key relationships including with Donald Trump and frequently travels to China to oversee strategic ties. Meanwhile, Art Levinson will take on the role of lead independent director.
During Cook’s tenure, Apple significantly expanded beyond its core iPhone and Mac businesses into wearables, health services and digital platforms. Annual revenue rose to $416 billion, while its installed base crossed 2.5 billion active devices.
The period also saw the introduction of larger iPhones, multiple iPad variants and services such as Apple Music and Apple TV. However, the company faced setbacks, including the Vision Pro headset and the discontinuation of a long-running self-driving car project.
Future Roadmap
Apple continues to trail competitors such as OpenAI, Anthropic and Alphabet Inc. in artificial intelligence, a segment expected to reshape consumer technology.
Ternus has recently reorganised the hardware engineering division to incorporate AI-led development processes aimed at improving efficiency and product quality. He is overseeing a pipeline of new devices, including upgraded AirPods, smart glasses and other wearable products, along with smart home technologies such as a facial-recognition display, a tabletop robotic device and a connected security system.
Cook has spent several months preparing Ternus for the transition by expanding his responsibilities across hardware, software design and prototyping initiatives.
“I look forward to working with you very closely in my new role. Needless to say, I still plan to be very hands-on,” Ternus said in a note to employees.
The transition comes amid broader leadership changes, with senior executives including Lisa Jackson, Jeff Williams, Dan Riccio and Alan Dye stepping down in recent months, alongside shifts in legal and finance roles.
“Today, we have a truly extraordinary road map, and I have never been more optimistic about Apple’s future,” Cook added, indicating that the timing was appropriate for his transition to executive chairman.
