[
Apple stock traded slightly down after-hours following the announcement that CEO Tim Cook will be stepping down, to be replaced by his hand-picked protégé, John Ternus. There is no question that Cook is one of the most legendary and accomplished CEOs of our time, but this short-sighted market reaction is entirely misguided. Here are three reasons why Apple’s CEO handoff from Cook to Ternus reflects a model succession process, with the company’s best days still ahead.
Cook Is Leaving on His Terms — and Apple Has Never Been Stronger
As Wedbush analyst Dan Ives commented on CNBC immediately after Apple’s announcement, Cook would not be leaving unless he felt confident about the hand he is passing to his successor—and what a hand it is.
Despite some analyst handwringing that misguidedly portrays Apple as a laggard in adopting AI based on a few well-documented false starts, Apple retains the pole position in distributing AI to its approximately 2 billion consumers worldwide, as we presciently said in Fortune last year. When it comes to the consumer adoption of artificial intelligence, all roads still run through Apple as the singular gatekeeper to an unparalleled user base.
This playbook has been a winning recipe for Apple time and time again, as Apple is never the first, but it is always the best. The fallacy of first is demonstrated by the Netscape, Napster, Sony’s Betamax, GM’s EV1 electric vehicle, Kodak’s first digital camera in 1975, and UPS’ launch of an overnight delivery service in 1929 as potent reminders that being first is not the winning formula; being the best is. Just as Apple never had the first personal computer or the first smartphone, but they ended up having the best; similarly, although Apple has long been criticized for not spending enough on AI; Apple is now perfectly positioned to pick AI winners and losers given their control of physical hardware.
This year is already poised to be transformational for Apple’s AI ecosystem. The pipeline ranges from the launch of an enhanced Siri powered by Gemini AI, to exciting developments in proprietary infrastructure—including in-house AI servers and custom silicon chips—alongside the highly anticipated launch of a foldable iPhone this fall.
Ternus Built the Hardware That Will Win the AI Era
Cook has chosen to leave at the top of his game as the culmination of a planned, deliberate succession process. The company has clearly signaled this transition over the last few months as John Ternus emerged publicly as the designated heir apparent.
A proven product architect and an engineer to his core, John Ternus is the right person at the right time. His fingerprints are on almost every major Apple hardware success over the past two decades. Ternus has been a driving force behind the transition from Intel processors to Apple’s proprietary custom silicon chips—the foundation of Apple’s AI efforts. Furthermore, he has been instrumental in the development of virtually every core product line, including AirPods and iPads, while revitalizing the entire Mac lineup.
Ternus’s hardware prowess is vital to Apple’s AI future. While AI models provide raw intelligence, Apple’s hardware acts as the ultimate gatekeeper to consumer/user adoption of AI. By elevating a master product architect, Apple is betting that the ultimate victor of the AI age will be the company that owns the final, most valuable mile of the consumer experience. Ternus has the clear mandate to leverage Apple’s unparalleled hardware footprint—controlling over 2 billion physical devices—to build the indispensable chassis for the consumer AI era.
Apple Has Always Been Bigger Than Any One CEO
Thirty-eight years ago, the first author’s bestseller The Hero’s Farewell (Oxford) broke new ground describing the challenges of following founders given the shadows of legendary entrepreneurs. Years later, Steve Jobs drew on this book when he personally complained to the first author about his own failed successors, Gil Amelio and John Sculley, insisting that they lacked commercial mastery over the technology that Jobs had advanced. When it came to Tim Cook, however, Jobs twice gave him the functioning CEO position without eagerly or formally surrendering the title, trusting Cook to never undermine him—even in his own moments of weakness amidst frail health and unclear corporate messaging.
After Jobs passed, many analysts were skeptical about Cook’s prospects of succeeding a larger-than-life legendary founder. One board member even suggested that the first author sell his Apple stock. Yet Cook immediately assumed the reins with a rare blend of energy and humility. He inspired others to innovate without any personal grandiosity, curtailed some of Jobs’s excesses, and transformed Apple into the world’s most valuable company along the way.
Jobs fully trusted Tim Cook to reengineer Apple’s global production process and supply chain. Consequently, Cook became the ideal leader to revisit that very process when geopolitics necessitated repatriating some businesses and friendshoring others. As the architect of this operational machine, Cook possessed the unique authority and insight required to overhaul it.
But Cook’s legacy extends far beyond his supply chain accomplishments. While Steve Jobs is rightly celebrated as the visionary behind Apple’s original success, it was early pioneers like Lee Felsenstein who engineered the first personal computers; Jobs simply possessed the genius to commercialize them. A similar dynamic defines Tim Cook’s legacy. He may have inherited the iPhone from Jobs, but it was Cook who scaled it into the most indispensable device on earth, transforming it into the singular hardware hub around which billions of people organize their daily lives. It is easy to forget that when Cook assumed the CEO role, the iPhone had less than a quarter of the US smartphone market, facing potent competitors like BlackBerry, Samsung, Motorola, and Nokia. That was a far cry from the iPhone’s dominant position today, capturing a third of the global market and nearly two-thirds of the US, which is a testament to Tim Cook’s commercial genius.
In a 1983 internal speech, Steve Jobs, the notorious perfectionist, complained about the speed of the Macintosh’s completion, quipping: “Real artists don’t hang on to their creations. Real artists ship. Matisse shipped. Picasso shipped.”
Jobs never got to see the full arc of Cook’s tenure, but the record speaks for itself: Tim Cook shipped. Cook moved past the navel-gazing of perfectionist designers to get the product out the door, scaling with unprecedented success. Creative ideas are only useful when they are implemented. Too often in technology, great products remain trapped in unfinished states—pitfalls Cook avoided with aplomb. His legacy as a visionary tech leader with unsurpassed skills in execution is indisputable, with his model succession handoff to his hand-picked protégé, John Ternus, reflecting the fact that Apple’s best days are still ahead.
