After 15 years at the helm of one of the world’s most influential technology companies, Tim Cook is stepping down as chief executive officer of Apple.
Apple announced on April 20, 2026, that Cook would leave the CEO position and become executive chairman of the company’s board of directors. John Ternus, Apple’s longtime senior vice president of Hardware Engineering, will become CEO on September 1, 2026 (Apple, 2026a).
The change marks the end of an extraordinary period in Apple’s history.
When Cook became CEO in August 2011, Apple was already a hugely successful technology company, thanks largely to products developed under co-founder Steve Jobs, including the Mac, iPod, iPhone and iPad. However, the scale of Apple today is dramatically larger.
Around the time Cook took over, Apple’s stock-market value was approximately $300 billion. By late August 2026, it was worth approximately $4.7 trillion, depending on the trading day and market-price measurement used (Stock Analysis, 2026; StatMuse, 2026).
That means Apple’s market value increased by more than 15 times during Cook’s period as CEO.
But market value tells only part of the story. Under Cook, Apple’s annual revenue grew from about $108 billion to more than $416 billion, annual net income rose from approximately $26 billion to $112 billion, the company developed enormous new businesses around services and wearable devices, and Apple returned more than $1 trillion to shareholders through dividends and share repurchases (Apple Inc., 2011, 2025; Financial Times, 2026).
Taking Over From Steve Jobs
Tim Cook officially became Apple’s CEO on August 24, 2011, after Steve Jobs resigned from the position because of declining health. Cook had previously served as Apple’s chief operating officer and had played an important role in managing the company’s worldwide operations and supply chain (Apple, 2011).
Taking over from Jobs was an enormous challenge.
Jobs was not simply Apple’s CEO. He was closely associated with the company’s identity and some of its most successful products. He had helped lead the development and introduction of products including the iPod, iPhone and iPad.
Cook was a very different type of leader. His reputation had been built largely around operations, logistics and supply-chain management rather than product design.
When Cook became CEO on August 24, 2011, historical market data put Apple’s market capitalization at approximately $296 billion for that trading day (StatMuse, 2026). Other financial analyses using somewhat different dates and methodologies put Apple’s value when Cook took over closer to $350 billion (Investopedia, 2026).
For this reason, it is reasonable to describe Apple as roughly a $300 billion company when Cook became CEO, while recognising that market capitalization changes every trading day.
Few could have predicted just how much larger Apple would become.
From About $300 Billion to Around $4.7 Trillion
The expansion of Apple’s market value during Cook’s leadership is one of the clearest measures of the company’s financial transformation.
By August 28, 2026, Apple had a market capitalization of approximately $4.67 trillion, according to Stock Analysis (2026).
Financial Times reported that Apple’s shares had risen by more than 2,000% during Cook’s tenure and that the company’s market value had reached the multi-trillion-dollar level (Financial Times, 2026).
The growth also allowed Apple to cross several historic milestones.
In August 2018, Apple became the first publicly traded American company to achieve a market capitalization of $1 trillion. It subsequently passed $2 trillion and $3 trillion before eventually entering the $4 trillion range.
These figures are important, but market capitalization should not be confused with revenue or cash held by the company. A company’s market capitalization represents the market value of its outstanding shares. It changes continually as its share price changes.
Therefore, saying that Cook transformed Apple from a roughly $300 billion company into a roughly $4.7 trillion company refers specifically to stock-market valuation, not annual sales or money sitting in Apple’s bank accounts.
Apple’s Revenue Nearly Quadrupled
The growth was not limited to Apple’s share price.
Apple reported $108.25 billion in net sales for its 2011 fiscal year. Its net income that year was approximately $25.92 billion (Apple Inc., 2011).
By fiscal 2025, Apple’s annual net sales had reached $416.16 billion, according to the company’s Form 10-K filed with the U.S. Securities and Exchange Commission (Apple Inc., 2025).
That represents an increase of approximately 285% from the 2011 level, meaning annual revenue became about 3.8 times as large.
Profit increased even more dramatically in dollar terms.
Apple’s annual net income increased from approximately $25.92 billion in 2011 to $112.01 billion in fiscal 2025 (Apple Inc., 2011, 2025).
In other words, Apple was earning more than four times as much annual profit near the end of Cook’s tenure as it reported during the fiscal year in which he became CEO.
The iPhone Became an Even Bigger Global Business
Cook did not create the iPhone. Steve Jobs introduced the original iPhone in 2007, four years before Cook became CEO.
However, Cook oversaw the period in which the iPhone became one of the world’s largest consumer-product businesses.
According to figures reported by the Financial Times using data from International Data Corporation (IDC), Apple shipped approximately 3.1 billion iPhones during Cook’s time as CEO (Financial Times, 2026).
The iPhone remained Apple’s single largest source of revenue.
In fiscal 2025 alone, Apple generated approximately $209.59 billion in iPhone sales (Apple Inc., 2025).
For perspective, Apple’s entire company generated only $108.25 billion in revenue in fiscal 2011.
That means that by 2025, annual revenue from the iPhone alone was almost twice Apple’s total company-wide annual revenue in 2011.
Cook Built a Huge Services Business
One of the most important transformations under Cook was Apple’s expansion beyond selling physical devices.
Apple developed a massive services ecosystem around products and platforms including:
- the App Store;
- iCloud;
- Apple Music;
- Apple TV+;
- Apple Pay;
- AppleCare; and
- other digital subscriptions and services.
By fiscal 2025, Apple’s Services division generated approximately $109.16 billion in annual revenue, compared with $96.17 billion the previous year (Apple Inc., 2025).
The scale is striking.
Apple’s Services business alone was generating roughly as much annual revenue by 2025 as the entire Apple company generated in 2011.
The Financial Times reported in 2026 that Apple had reached approximately 1.5 billion paid subscriptions across services on its platforms (Financial Times, 2026).
This shift helped make Apple’s business less dependent on customers purchasing a new device for every dollar of revenue.
Apple Watch and AirPods Created New Product Categories
Although critics sometimes argue that Apple did not produce another product as revolutionary as the iPhone during Cook’s leadership, several important new hardware categories appeared under him.
The Apple Watch was introduced in 2014 and released in 2015. AirPods arrived in 2016.
Both developed into major global product lines.
Cook’s era also included products and platforms such as Apple Silicon-powered Macs, HomePod, AirTag and Apple Vision Pro.
Apple’s transition from Intel processors to its own Apple-designed chips for Macs was particularly significant. The move gave Apple greater control over the integration of hardware and software across its computers.
Not every new product became a business on the scale of the iPhone, but Cook’s Apple became much broader than the company he inherited.
More Than 2.5 Billion Active Apple Devices
Another indication of Apple’s expansion is the size of its installed device base.
By 2026, Apple reported more than 2.5 billion active devices worldwide, according to figures cited by the Financial Times (2026).
This enormous installed base is strategically important because customers using iPhones, Macs, iPads, Apple Watches and other devices can also purchase apps, subscriptions, cloud storage and other Apple services.
The combination of hardware, software and recurring services became one of Apple’s most important competitive strengths during Cook’s leadership.
More Than $1 Trillion Returned to Shareholders
Cook’s tenure was also notable for Apple’s enormous capital-return programme.
Apple began paying a regular dividend again in 2012 and launched a major share-repurchase programme.
Over Cook’s tenure, Apple returned more than $1 trillion to shareholders through share buybacks and dividends, according to the Financial Times (2026).
Share repurchases reduce the number of Apple shares outstanding and can increase the portion of the company represented by each remaining share.
The scale of the programme reflected Apple’s enormous ability to generate cash.
Apple’s Workforce Also Expanded
Apple became considerably larger as an organisation during Cook’s leadership.
According to the Financial Times (2026), Apple’s direct workforce expanded from roughly 60,000 employees to about 166,000 employees during Cook’s time as CEO.
The company’s physical retail presence also expanded internationally, reaching more than 500 stores across dozens of countries and regions.
Cook therefore leaves behind not only a company with a much larger valuation, but also a significantly larger global organisation.
Cook’s Record Was Not Without Problems
The extraordinary financial results do not mean Cook’s tenure was free of criticism.
One of the most persistent criticisms has been that Apple became more cautious about breakthrough innovation.
The iPhone, iPad and Mac remained central to Apple’s hardware business, while competitors moved aggressively into areas such as generative artificial intelligence.
Apple’s difficulties in developing and deploying some promised artificial-intelligence features became an important issue toward the end of Cook’s tenure.
The company has also faced regulatory pressure around the world over the App Store and its control over the Apple ecosystem.
Another major challenge is Apple’s supply chain.
Cook’s operational expertise helped Apple create one of the world’s most sophisticated technology manufacturing networks, but the company’s substantial dependence on manufacturing in China has also created geopolitical and economic risks.
The Financial Times (2026) noted both the extraordinary financial achievements of Cook’s tenure and the challenges his successor will inherit, including artificial intelligence, regulation and Apple’s exposure to China.
These issues form an important part of Cook’s record and prevent his tenure from being viewed purely through Apple’s rising share price.
John Ternus Takes Over
Apple has selected John Ternus to succeed Cook.
Ternus has spent many years at Apple and served as senior vice president of Hardware Engineering. Apple announced that he will officially become chief executive officer on September 1, 2026 and will also join the company’s board of directors (Apple, 2026a).
Cook is not leaving Apple completely.
Instead, he will become executive chairman of Apple’s board. Apple said he will continue helping the company in certain areas, including engagement with policymakers around the world (Apple, 2026a).
Arthur Levinson, who served as Apple’s chairman for 15 years, will become lead independent director.
The arrangement means Apple will enter a new era while retaining Cook in an influential position.
Tim Cook’s Apple in Numbers
The scale of the transformation becomes particularly clear when some of the major figures are placed side by side:
Market capitalization: Approximately $296 billion around the day Cook became CEO in August 2011; approximately $4.7 trillion by late August 2026.
Annual revenue: $108.25 billion in fiscal 2011; $416.16 billion in fiscal 2025.
Annual net income: $25.92 billion in fiscal 2011; $112.01 billion in fiscal 2025.
Services revenue: $109.16 billion in fiscal 2025 alone.
iPhone revenue: $209.59 billion in fiscal 2025.
iPhones shipped during Cook’s tenure: Approximately 3.1 billion, according to IDC figures reported by the Financial Times.
Active Apple devices: More than 2.5 billion globally by 2026.
Capital returned to shareholders: More than $1 trillion during Cook’s tenure.
Employees: From roughly 60,000 to approximately 166,000.
These figures use different measurement periods because Apple’s fiscal-year financial statements, daily stock-market valuations and operational statistics are reported on different schedules. They should therefore be treated as indicators of scale rather than as measurements taken on exactly the same date.
The End of a Remarkable 15-Year Run
Tim Cook inherited a very different Apple from the one he will hand over to John Ternus.
He did not invent the iPhone, nor can Apple’s success during his tenure be attributed to one person. Apple entered the Cook era with exceptionally valuable products, technology, intellectual property and employees created and assembled under Steve Jobs and other Apple leaders.
Nevertheless, the financial expansion under Cook is difficult to overstate.
Apple went from approximately $108 billion in annual revenue to more than $416 billion. Annual net income increased from approximately $26 billion to $112 billion. The company developed a Services operation producing more than $100 billion a year, shipped billions of iPhones and built an installed base exceeding 2.5 billion active devices.
Most strikingly, a company valued at roughly $300 billion when Cook became CEO grew to approximately $4.7 trillion by the end of his tenure.
Cook therefore leaves the CEO position having overseen one of the largest increases in corporate value in modern business history.
Whether Apple can produce another transformation of similar magnitude will now become the responsibility of John Ternus and the next generation of Apple’s leadership.
