John Ternus Replaces Tim Cook

Tim Cook will step down as Apple’s CEO on September 1, 2026, becoming executive chairman, while John Ternus, senior vice president of Hardware Engineering, will become the new CEO. Ternus is expected to bring a more decisive, product-focused leadership style akin to Steve Jobs, focusing on hardware excellence and potentially addressing ongoing software quality and developer relations issues. The transition marks the end of Cook’s 15-year tenure during which Apple grew substantially in services and wearables, but also faced criticism for software decline and lack of innovation.
