Tim Cook’s Imminent Retirement Sharpens the Spotlight on His $4 Trillion Apple Legacy: the Race to Succeed Him

By Eberechukwu John November 22, 2025

Tim Cook’s tenure as Apple CEO may be approaching its final chapter

After more than a decade at the helm of the world’s most valuable technology company, Tim Cook’s tenure as Apple CEO may be approaching its final chapter. A recent report from the Financial Times, citing multiple senior insiders, suggests Cook could step down as early as next year, triggering one of the most consequential leadership transitions in modern business history.

Apple has not commented publicly on the speculation, but reports indicate that Cook, now 65, is deeply involved in accelerated succession planning. While some analysts believe he could shift into a more strategic role, possibly as chairman of the board, others argue the leaks are a deliberate move to prepare markets and customers for an eventual handover.

Most observers agree the transition is unlikely before Apple’s next earnings call in January, but a change in leadership before the mid-2026 Worldwide Developers Conference (WWDC) is now widely seen as plausible.

A Legacy Defined by Reinvention and Relentless Scale

When Cook succeeded

in 2011, Apple’s market capitalization hovered around $350 billion. Today, that figure has soared to nearly $4 trillion, making Apple the most valuable company on the planet and cementing Cook as one of the most successful CEOs in history.

His leadership style, calm, operationally disciplined, and strategically patient, stands in stark contrast to Jobs’ fiery vision. Yet it was Cook who transformed Apple from a hardware-centric giant into a diversified global ecosystem.

A Company Transformed Under His Watch

Cook’s Apple has introduced:

48 iPhone models, from the iPhone 4 to today’s iPhone 17 Pro
Entirely new product categories: Apple Watch, AirPods, Apple Vision Pro
A redesigned Mac line, powered by the industry-shifting M-series chips
A booming services empire, including Apple Music, TV+, Arcade, Fitness+, and Pay
The world’s most profitable subscription ecosystem

He also reorganized Apple’s famously segmented internal structure by removing conflicting leadership figures like Scott Forstall and redistributing responsibilities across teams—an early, bold move that earned Cook internal trust.

Apple’s operational strength, supply-chain dominance, and global retail ecosystem all grew dramatically under his stewardship.

“Tim Cook turned Apple into the most valuable business in the world while keeping its products central to everyday life,” said Natalie Andreas, professor of communication management at the University of Texas.

The Criticism: A Slow Start in the AI Race

Despite Apple’s immense success, Cook’s later years have attracted criticism. Rivals like Google, Meta, and OpenAI have surged ahead in generative AI, while Apple’s own offering, Apple Intelligence, has rolled out gradually, with many features still in beta.

Additionally, Bloomberg recently reported Apple has cancelled its lighter Vision Pro model to shift resources into AI-powered smart glasses, signalling an increasingly competitive future in wearable computing.

Whoever replaces Cook will need to confront a landscape defined by:

Rapid AI competition
The rise of spatial computing
Regulatory pressures in the EU and the US
A saturated smartphone market
The need for the next “big thing”

In other words, the next CEO will inherit an empire, but one full of high-stakes challenges.

The Leading Successor: John Ternus

Inside Apple’s executive suite, one name has increasingly surfaced: John Ternus, the company’s Senior Vice President of Hardware Engineering.

A 23-year Apple veteran, Ternus has played a central role in nearly every major hardware breakthrough of the Cook era.

A Career Built Behind the Scenes

Joined Apple in 2001 as a product designer
Rose to VP of hardware engineering in 2013
Led development of the iPad, Mac, and AirPods
Took over iPhone hardware in 2020
Became SVP of hardware engineering in 2021
Oversaw the entire Apple Watch hardware division from 2022

Ternus was instrumental in one of Apple’s most defining engineering achievements: the transition from Intel processors to Apple’s own M-series chips, which revolutionized performance and battery efficiency across the Mac lineup.

He has increasingly become one of Apple’s public faces, appearing at major product launches and interacting with customers, a role Cook began assuming shortly before he became CEO.

“Ternus blends deep engineering expertise with a people-first philosophy reminiscent of Apple’s early culture,” said Steven Athwal, CEO of The Big Phone Store. “He’s trusted by Cook and respected by Apple loyalists.”

Bloomberg’s Mark Gurman notes that Apple likely needs “more of a technologist than a sales or operations person” at the top, another reason Ternus leads the shortlist.

At 50 years old, he is roughly the same age Cook was when he took over in 2011—a symbolic detail that hasn’t gone unnoticed within the company.

What Cook’s Exit Would Mean for Apple

A Cook retirement would mark the end of a transformative era. Apple’s culture, product cadence, and global influence have all been shaped by his measured, methodical leadership. Analysts say Cook’s successor will inherit:

a nearly $4 trillion company
soaring investor expectations
an imperative to excel in AI and spatial computing
an ecosystem of over 2 billion active devices
a workforce of 160,000 employees

But they will also inherit Cook’s greatest achievement: a company built to outlive any one leader.

If Ternus—Apple’s quiet, engineering-driven powerhouse- ultimately steps into the role, it would signal Apple’s intent to define the next era around breakthrough hardware, smarter devices, and AI woven seamlessly into everyday life.

As the world waits for an official announcement, one thing is clear:

Tim Cook’s story is entering its final chapter, but Apple’s next act is just beginning.
