After 15 years at the helm of Apple, Tim Cook has concluded his tenure as CEO of one of the world’s most valuable and influential companies. From 1 September, John Ternus takes over as CEO, while Cook remains at Apple as Executive Chairman of the board.
The transition brings to a close an era that began in 2011, when Cook inherited from Steve Jobs a company valued at around US$350 billion. Today, Apple is worth approximately US$4.6 trillion. During his tenure, annual revenue grew from just over US$100 billion to more than US$400 billion, while Apple shares gained nearly 2,300%.
These figures help illustrate the scale of his time at the company. But perhaps they do not fully explain what made his leadership so distinctive.
When Tim Cook took over Apple in August 2011, he faced a challenge few executives would want to inherit: succeeding Steve Jobs.
Jobs was not simply the company’s founder. He was the face of Apple, one of the most recognisable figures in technology and an inseparable part of the narrative built around the brand.
Cook had a completely different profile. Less associated with the spectacle of product launches and better known for his operational expertise, he did not attempt to replicate his predecessor’s style.
Under his leadership, Apple expanded its global presence, strengthened its supply chain, created new product categories with devices such as the Apple Watch and AirPods, developed its own chips for the Mac and transformed services into a major source of revenue.
The company Cook hands over to John Ternus is therefore very different from the one he inherited from Jobs.
Perhaps one of the greatest lessons from Tim Cook’s career lies precisely in the way he handled one of leadership’s most difficult challenges: taking over from someone widely regarded as irreplaceable.
Cook did not try to become the next Steve Jobs. He developed his own way of leading.
If Jobs became associated with the ability to imagine products capable of transforming markets, Cook consolidated Apple’s ability to turn innovation into global scale. His tenure demonstrated that extraordinary companies do not depend solely on great ideas. They also require execution, culture, processes and the ability to grow without losing what made the brand relevant in the first place.
In his final message as CEO, Cook chose to speak less about numbers and more about people. He said that what made him proudest about Apple was something no annual report could ever capture: its culture.
Now, the same question that followed Cook in 2011 passes to John Ternus.
How do you take over a company so deeply associated with the leader who came before you without simply trying to replicate them?
Tim Cook’s story offers one possible answer: great successors do not need to imitate those who came before them. They need to understand what should be preserved — and discover what only they can add.
Does a leader’s greatest legacy lie in the results they deliver, or in the company they leave prepared to continue growing without them?
