Cook will transition to executive chairman on September 1 as the 25-year Apple veteran Ternus
One of the most consequential leadership transitions in the history of American technology became official on Monday. Apple announced that Tim Cook is stepping down as chief executive officer, with hardware engineering chief John Ternus set to succeed him on September 1, 2026. Cook will remain in his current role through the summer before transitioning to executive chairman of the board, where he will continue to assist the company with select responsibilities including engagement with policymakers around the world.
The move, approved by Apple‘s board of directors, is the result of what the company described as a thoughtful, long-term succession planning process. Current board chair Arthur Levinson will step into the role of lead independent director as part of the broader leadership restructuring. Ternus will also join Apple’s board ahead of formally assuming the CEO title.
The end of a defining era
Cook took over as Apple’s chief executive in August 2011, stepping in following the health-related departure of co-founder Steve Jobs, who died just weeks later. In the years since, Cook transformed Apple from an already iconic consumer technology company into the most valuable business on earth, overseeing the expansion of the iPhone into global dominance, the launch of the Apple Watch, AirPods and Apple Silicon, and the dramatic growth of Apple’s services business into a multibillion-dollar revenue engine.
His tenure has been defined not only by commercial success but by a distinctive leadership philosophy centered on supply chain mastery, operational discipline and a willingness to engage publicly on issues ranging from privacy and encryption to climate change and human rights. Under Cook, Apple became as much a cultural institution as a technology company — a shift that his successor will inherit alongside the considerable weight of expectation that comes with leading it.
In a statement released Monday, Cook called his time as Apple’s CEO the greatest privilege of his life, expressing deep gratitude for the team he has led and full confidence in the man he is handing the company to.
Who is John Ternus?
Ternus has spent nearly his entire professional career at Apple, joining the company roughly 25 years ago and rising through the hardware engineering organization to become one of its most senior and respected figures. As Apple’s head of hardware engineering, he has been responsible for overseeing the physical design and development of the company’s core product lines — including the iPhone, Mac, iPad and Apple Silicon chips — during one of the most technically ambitious periods in the company’s history.
His elevation to CEO represents a clear signal from Apple’s board that the company’s next chapter will be led by someone who understands its products from the inside out. Cook described Ternus as possessing the mind of an engineer, the soul of an innovator and the integrity required to lead one of the world’s most scrutinized organizations.
Ternus, for his part, acknowledged the magnitude of the moment while striking a tone of determined optimism. Having worked under both Steve Jobs and Tim Cook over the course of his career, he said he is humbled by the opportunity and committed to leading with the values and vision that have defined Apple for more than half a century. He expressed particular confidence in the depth of talent within the company, calling the people at Apple the most capable on earth.
What comes next for Apple
The transition arrives at a pivotal moment for the technology industry broadly. Artificial intelligence has emerged as the dominant competitive battleground among the world’s largest tech companies, and Apple — which has moved more deliberately than some of its rivals in deploying AI features to consumers — faces significant pressure to accelerate its efforts in that space under new leadership.
Ternus brings engineering credibility that few successors in Apple’s history could match, and his deep familiarity with the hardware and chip architecture that underpins Apple’s AI capabilities may prove to be a defining advantage as the company charts its next decade. Cook’s continued presence as executive chairman also provides a degree of continuity and institutional knowledge that will likely shape Ternus’s early tenure in meaningful ways.
The formal handover takes effect September 1, 2026.
