Tim Cook Steps Down as Apple CEO — John Ternus Takes the Helm on September 1
Apple announced Tim Cook will become Executive Chairman while SVP of Hardware Engineering John Ternus becomes CEO. The transition marks the first leadership change at Apple since Cook took over from Steve Jobs in 2011.
Apple announced Monday that Tim Cook will step down as CEO effective September 1, 2026, handing the role to John Ternus, 50, currently Senior Vice President of Hardware Engineering. Cook moves to Executive Chairman.
The announcement ends a 15-year run that saw Apple become the first company to reach a $3 trillion market cap, build out its services empire, and navigate the most complex global supply chain in consumer electronics. Cook took over from Steve Jobs in August 2011.
Ternus joined Apple in 2001 and has spent the last several years overseeing the hardware that defines the company’s premium position: iPhone, Mac, iPad, and AirPods. His fingerprints are on the M-series silicon transition, the iPhone 15 Pro’s titanium chassis, and the Vision Pro. He is widely regarded inside Apple as the architect of the hardware roadmap that will carry the company through the AI hardware era.
The board approved the transition unanimously. Johny Srouji, who runs semiconductor engineering, becomes Chief Hardware Officer — a new title that signals where Apple expects its next decade of differentiation to come from. Arthur Levinson, the longtime board member who also chairs Genentech, becomes Lead Independent Director.
What this means for Apple’s direction is worth parsing carefully. Cook’s 15 years were defined by operational mastery: supply chain discipline, services monetization, and methodical product expansion. Ternus is a hardware engineer. His ascension at exactly the moment AI-capable silicon is becoming the most important variable in personal computing is not a coincidence. Apple’s next-generation chip programs, Apple Intelligence’s upcoming revision, and the rumored smart glasses all land on his desk on day one.
The market reacted calmly. Apple shares moved less than 1% in after-hours trading — a sign that investors either saw this coming or trust the board’s succession planning enough not to panic.
Cook’s exit from the day-to-day job does not mean he disappears. Executive Chairman is a real role at Apple. He will remain engaged with major strategic decisions, government relations, and investor communications. But day-to-day operations, product reviews, and the weekly executive team meetings transfer to Ternus.
The last CEO transition at Apple in 2011 was forced by illness and felt abrupt even to insiders. This one appears to have been planned over multiple years, a fact the board emphasized in its announcement. Whether Ternus can sustain the growth trajectory Cook built — or whether he reshapes Apple around a harder-edged hardware ambition — is the question the next decade will answer.
