Apple announced on Monday, 20 April 2026, that Tim Cook will step down as Chief Executive Officer on 31 August. John Ternus, the company’s current Senior Vice President of Hardware Engineering, takes over on 1 September 2026. Cook transitions to Executive Chairman of the board, with a focus on policy engagement around the world. The change, per Apple’s official newsroom post, was unanimously approved by the board and follows what Apple calls a “thoughtful, long-term succession planning process.”

Arthur Levinson, Apple’s non-executive chairman for 15 years, becomes lead independent director on the same day. Johny Srouji, the longtime silicon chief, was also promoted to Chief Hardware Officer, taking over Ternus’s hardware engineering duties effective immediately.

This is Apple’s first CEO change since Cook succeeded the late Steve Jobs in August 2011.

Who is John Ternus?

Ternus, 50, has spent nearly his entire career at Apple. He joined the product design team in 2001 after graduating in mechanical engineering from the University of Pennsylvania and a brief stint at Virtual Research Systems, a small VR headset firm. He was promoted to Vice President of Hardware Engineering in 2013 and to Senior Vice President in 2021, becoming the youngest member of Apple’s executive team at the time.

His fingerprints are on nearly every recent Apple device. He oversaw the hardware teams behind the iPhone, iPad, Mac, Apple Watch, AirPods, and Vision Pro, and most recently led the development of the MacBook Neo, Apple’s first low-cost MacBook, launched last month. Many Apple watchers had already tipped him as the obvious successor.

Cook’s Legacy: From Jobs to $4 Trillion

When Cook took over in 2011, Apple was worth about $350 billion and was mourning Jobs, who died just six weeks after handing over. Today Apple’s market cap sits at more than $4 trillion, up more than 20-fold. Apple’s stock has appreciated over 1,700% on his watch.

Cook was never supposed to be a showman. Jobs hired him in 1998 to fix Apple’s broken supply chain. Cook, a former IBM and Compaq operations expert, closed warehouses, consolidated suppliers, and eventually turned Apple’s manufacturing into a competitive weapon. That operational muscle is what allowed Apple to ship hundreds of millions of devices a year without stockouts.

His quieter style also shifted the company. In 2014 he became the first Fortune 500 CEO to publicly come out as gay, a moment widely seen as cultural history. He aligned Apple more visibly with privacy, the environment, and manufacturing diplomacy, most recently navigating the Trump administration’s tariff pressure.

The Biggest Changes Since Jobs

Under Cook, Apple stopped being mainly an iPhone, iPad and Mac company and became an everywhere company.

Wearables exploded. Apple Watch arrived in 2015 and is now the world’s best-selling watch. AirPods landed in 2016 and quietly built a multibillion-dollar business of their own.

Services became a quiet giant. Apple Pay (2014), Apple Music (2015), Apple TV+ (2019), Arcade, Fitness+, and iCloud together now generate tens of billions annually and cushion Apple against hardware cycles.

Silicon independence changed the Mac forever. Apple dropped Intel and shipped the M1 chip in 2020, starting a performance and battery leap that the PC industry is still trying to match.

And the consumer iPhone kept getting bigger and pricier. The iPhone 17 series launched last September with flagship prices starting at around KES 125,000 in Kenya and the Pro Max crossing KES 380,000 at some local resellers, a reminder of how far the product line has drifted from its original price bands.

Not everything worked. The Vision Pro, a Cook-era bet on mixed reality, launched in 2024 at over $3,499 and has struggled to find mass buyers. Apple has also been criticised for lagging in generative AI, delaying a major Siri upgrade and revamping its AI leadership late last year by bringing in a Google veteran. An updated Siri built on a Google Gemini model is now expected this year.

What Ternus Inherits

Ternus takes over a company still dominant but facing real headwinds. Generative AI rivals like OpenAI and Google have moved faster. Tariffs and geopolitical friction with China complicate the supply chain Cook perfected. Memory costs are rising as AI chip demand surges. And with Jony Ive long gone to OpenAI, Apple has been without a cornerstone designer for years.

The message from picking Ternus is clear. Apple is betting that the next era will be won on hardware and product, not marketing. As Cook put it in his statement, Ternus has “the mind of an engineer, the soul of an innovator, and the heart to lead with integrity.”

Starting 1 September, we find out if that’s enough.
