apple continues its long-standing tradition of promoting from within with the addition of a new CEO to its ranks.
The iPhone maker announced Monday that Chief Executive Officer Tim Cook will step down as CEO in September and named John Tarnas, senior vice president of hardware engineering, to take his place. Mr. Cook will become executive chairman.
In a press release announcing Ternas’ appointment as CEO, Cook wrote that Ternas has “the heart of an engineer, the soul of an innovator, and the heart to lead with integrity and honor.”
Industry experts have long speculated that the 51-year-old Ternas Apple veteran would be Mr. Cook’s eventual successor. For the past 25 years, Ternus has been a key architect of the tech giant’s powerful product pipeline, managing the hardware engineering for the iPad, AirPods, and recent iPhone models.
Tarnas will become the company’s eighth CEO when he takes over in September. He also faces significant obstacles in revamping the company’s struggling artificial intelligence strategy.
Apple is facing pressure to innovate its AI strategy, which has long been seen as lagging behind its mega-cap peers. The company recently stalled on developing an AI-powered Siri model and enlisted the help of Google’s Gemini in January.
Wall Street analysts see the CEO’s promotion as a potential catalyst to reignite optimism about Apple and its AI strategy.
“Elevating him to CEO clearly signals Apple’s continued focus on products at the center of its flywheel,” Morgan Stanley analysts wrote.
The path to CEO
Ternus graduated from the University of Pennsylvania in 1997 with a degree in mechanical engineering. During his school days, he combined his studies with a competitive swimming career.
After graduating, I worked as an engineer at Virtual Research, an early company developing VR headsets. He joined Apple in 2001 as an engineer on the design team.
In his 2024 Commencement speech for the University of Pennsylvania School of Engineering, Ternas described his first day at the tech company as “both exhilarating and intimidating.”
“I wasn’t sure if I belonged there,” he recalls. “I will always be grateful that the people I met were so smart and confident and knew so much more than I did, but were not afraid to ask for help when they needed it.”
His first project at this fast-growing technology company was a plastic desktop monitor known as a cinema display. He described the construction as a detailed process involving “large, intricate transparent plastic parts.” After that, Apple shifted its focus to aluminum.
“All these experiences have honed my ability to approach problems from different angles. These experiences have given me the confidence and willingness to try new things and the determination to keep moving forward until I find a solution,” he told students in 2024.
By 2013, Ternus became vice president of hardware engineering, leading the development of major product lines including the Mac and iPad. He became Apple’s head of iPhone and became senior vice president of hardware engineering in 2021, when then-head of hardware Dan Riccio shifted his focus to Apple Vision Pro.
Over the past five years, Ternus has overseen the design and product performance of many new Apple products, including the iPad and AirPods. He has also played a key role in Apple’s transition from a silicon chip program to a silicon chip program. intel.
For Apple fans, Ternus is a familiar face at launch events broadcast from the company’s Cupertino headquarters. Last year, he announced the company’s new iPhone Air.
In a statement announcing his appointment, Ternas said he was “lucky” to have worked for Apple founder Steve Jobs and to have Cook as a mentor.
“I’m full of optimism about what we can accomplish in the coming years. I’m so happy to know that some of the most talented people on the planet are here at Apple and are determined to be part of something bigger than any of us,” he said.
