Apple Announces CEO Transition: Tim Cook to Step Down, John Ternus to Take Over

Apple announced a major leadership change, with CEO Tim Cook set to step down in September and transition to the role of executive chairman. John Ternus, the senior vice president of hardware engineering, will succeed him as CEO effective September 1.

The company stated that the handover is part of planned succession to ensure continuity. Cook, who has led Apple since August 2011, will continue to assist with certain aspects, including engagements with policymakers worldwide. Sources confirmed that this includes interactions with figures such as President Trump.

Apple highlighted Ternus' long tenure and contributions to key products.

Ternus has led Apple's hardware engineering since 2013 and has been involved in developing products like the iPhone, iPad, and Mac. He joined the company in 2001 and rose through the hardware engineering ranks. Apple described his role in the company's hardware advancements as significant.

Under Cook's leadership, Apple's market capitalization grew from approximately $350 billion in 2011 to $4 trillion as of March 2026. The company expanded into services, wearables, and other sectors during this period. Cook joined Apple in 1998 and became CEO in 2011, marking a 15-year tenure in the top role.

The announcement aligns with Apple's internal succession planning, and the company emphasized a smooth transition process. Ternus has remained largely out of the public spotlight until now and will lead one of the world's most valuable companies starting in September.

No immediate stock market reactions were detailed in the announcements. The change occurs as Apple continues to innovate in AI, hardware, and services. Sources agreed on the factual details without contradictions.

The leadership shift marks the end of Cook's era as CEO, following his oversight of significant growth and diversification. Apple did not specify reasons for the timing beyond planned succession. Multiple sources, including AP and BBC, confirmed the September timeline and Ternus' current role.

TechCrunch noted that Ternus' elevation positions him to guide Apple's future direction. The Verge reported on Cook's ongoing policy engagements, including with President Trump. NPR specified the exact handover date and Ternus' background in hardware engineering.
