Who Is John Ternus? The Man Set To Succeed Tim Cook As Apple CEO

Apple Inc. named insider John Ternus as its next chief executive, marking a significant leadership transition as the company navigates an industry shift driven by artificial intelligence.

Tim Cook will step down as CEO on September 1 after leading Apple since 2011, and will take on the role of executive chairman.

65-year-old Cook, who ran Apple for 15 years after taking the reins from its visionary co-founder Steve Jobs, will be succeeded by Ternus, a senior vice president of hardware engineering

Calling it the “greatest privilege" of his life, Cook said in a statement that leading Apple had been an extraordinary journey.

Ternus has been with Apple for more than two decades and is known for his work in hardware.

Ternus joined Apple's product design team in 2001 and became a senior vice president of hardware engineering over the next two decades. He is credited with playing roles in several products including iPhones, iPads, the Apple Watch and Mac computers.

After joining Apple, Ternus rose through the ranks to become vice president of hardware engineering in 2013. In 2021, he was elevated to the executive team as senior vice president of hardware engineering, working closely with Cook on key product decisions.

Over the years, Ternus has overseen development across Apple’s core product lineup, including the iPhone, iPad, Mac, Apple Watch, and AirPods. He is also credited with helping revive Mac sales, which have gained market share in recent years.

Most recently, Ternus led the unveiling of the iPhone Air, the most significant redesign of Apple’s flagship smartphone since 2017, highlighting the company’s continued focus on hardware-led innovation.

Before joining Apple, Ternus worked at Virtual Research Systems and holds a degree in mechanical engineering from the University of Pennsylvania.

Known for his deep product expertise and steady execution, Ternus has played a key role in shaping some of the company's most important hardware innovations.

His elevation comes at a critical time, as Apple faces intensifying competition and a broader shift toward AI-driven technologies reshaping the consumer electronics landscape.

Cook joined Apple in 1998, and succeeded Steve Jobs as Apple CEO in 2011, steering the company into a phase of scale and services-led expansion.

Ternus said in Apple's announcement that he was "humbled to step into this role, and I promise to lead with the values and vision that have come to define this special place for half a century.”

Ternus, 50, has spent almost his entire career with Apple. He joined the company 25 years ago.
