John Ternus Takes Over as Apple CEO, Replacing Tim Cook | Apple has officially appointed John Ternus as its new Chief Executive Officer, replacing Tim Cook after 15 years at the helm.
The leadership change took effect on Tuesday, September 1, 2026. Cook has now moved into the role of executive chairman of Apple’s board.
Ternus, 51, is a long-serving Apple executive who joined the company in 2001. Before becoming CEO, he served as senior vice president of Hardware Engineering. He played a major role in the development of products including the iPhone, Apple Watch, AirPods and Apple Vision Pro.
Cook leaves after 15 years
Cook became Apple CEO in 2011, succeeding the company’s co-founder Steve Jobs.
During his tenure, Apple expanded significantly. The company grew into a technology giant with a market value of more than $4 trillion. It also expanded its services business while strengthening its global supply chain. However, Cook’s departure comes at a challenging time for Apple.
The company is facing growing pressure in artificial intelligence (AI). Rivals such as Google and Microsoft have moved aggressively in the sector, while Apple has faced criticism over the pace of its AI development.
Ternus faces major challenges
Ternus now takes charge as Apple prepares for its next phase of growth. His engineering background could place greater emphasis on product development and innovation. At the same time, he will have to address Apple’s position in the fast-changing AI industry.
Additionally, Apple continues to manage complex global supply-chain issues. The company has been working to reduce its dependence on manufacturing in China by expanding production in countries such as India and Vietnam.
Meanwhile, Cook will remain involved with Apple as executive chairman. The company said he will assist with certain areas, including engagement with policymakers around the world. Therefore, while Apple has entered a new leadership era, Cook’s continued presence is expected to provide some continuity as Ternus begins his tenure.
