Tim Cook worked his last day as Apple’s chief executive on August 31, 2026, closing out a 15 year run that turned the iPhone maker from a roughly 350 billion dollar company into the second business in history to touch a 5 trillion dollar market capitalization. John Ternus, Apple’s senior vice president of hardware engineering, took over as CEO effective September 1, while Cook moves into the newly created role of executive chairman, according to Apple’s official announcement.
The move was not a surprise by the time it happened, since Apple disclosed the succession plan back in April 2026, giving investors, employees and the wider tech industry more than four months to prepare for the handoff. What arrived on the actual transition date was still a milestone, marking the end of the longest CEO tenure in Apple’s modern history and the start of an era in which a career hardware engineer, rather than a supply chain operator, runs the company.
When Cook became Apple’s CEO in August 2011, he had big shoes to fill, succeeding Steve Jobs, widely considered one of the world’s greatest innovators. Fifteen years later, Cook catapulted the company to stratospheric heights by forging his own path, becoming remembered for making the iPhone feel essential to everything from buying a coffee to listening to music, hitting the gym or paying a credit card bill, largely through the web services and accessories business he pioneered over the past decade. Apple’s stock soared by more than 2,000 percent during his tenure, and the company briefly reached a 5 trillion dollar market capitalization in July.
Ternus inherits a company with enormous financial strength and a loyal global customer base, but also one facing questions about whether it can move quickly enough in artificial intelligence. The timing is significant, with Apple recently unveiling upgraded Mac mini and Mac Studio computers powered by newer chips designed to handle increasingly demanding AI workloads, underscoring the importance of on-device computing and custom silicon to the company’s strategy going forward. For Cook, the transition marks the end of an era that saw Apple evolve from a consumer electronics company into a vast ecosystem spanning devices, services, chips, payments and digital content, while the next phase of Apple’s growth will test whether the operational model Cook built can be combined with the product and engineering focus his successor is expected to bring.
