Yesterday, 31 August 2026, was Tim Cook's last day as chief executive of Apple. Today John Ternus took office. The move was announced in advance, on 20 April, with unanimous board approval, and Cook continues as executive chairman.
Fifteen years is a period you can measure. These are the two numbers that frame it, and after them the more interesting question - what explains the gap between them.
Errors or inaccuracies are possible. Spotted something that looks wrong? Write to me and I will correct it.
The Two Numbers
| 2011 | Today | |
|---|---|---|
| Annual revenue | $108 billion | $416 billion (fiscal 2025) |
| Market value | about $350 billion | touched $5.036 trillion on 28 July 2026 |
Revenue grew 3.9 times over. Market value grew 14 times over.
A company that quadruples revenue in fifteen years is a very good company. A company whose value rises fourteenfold over the same period did something additional, and what sits in that gap is the subject of this piece.
On 28 July this year Apple became the second company in history to touch five trillion dollars, after Nvidia, which got there in October 2025. As of today it trades below that mark, at a value of about $4.6 trillion.
Who Cook Was Before He Was Chief Executive
This is the background that explains most of what followed, and it is not the background of a product person.
Cook spent 12 years at IBM and rose to run North American distribution. He then passed through Intelligent Electronics and Compaq. Steve Jobs recruited him in March 1998, as senior vice president of worldwide operations.
His field was supply chain: just-in-time manufacturing, inventory reduction, and component purchase contracts. These are not subjects that generate headlines, and they are not subjects that generate products. They generate margin.
When Jobs handed him the job in August 2011, the public question was whether an operations man could run a product company. In hindsight that question missed what actually happened - Cook did not try to be a product manager. He took operational discipline and applied it to everything else in the company.
The First Engine: A Change in Mix, Not Only in Size
The difference between selling devices and selling services is not only in the revenue. It is in the margin, and above all in its stability.
Under Cook, Apple's Services segment grew from under $10 billion a year to more than $100 billion. In the fourth quarter of fiscal 2025 alone it recorded $28.8 billion, up 15%.
The point here is not the size of the segment but what it does to the multiple.
Revenue from selling a phone is a one-off event dependent on a replacement cycle. Revenue from a subscription, an app store commission or a search agreement is a recurring stream. Capital markets price those two kinds of revenue at entirely different multiples, even when the amount is identical.
That is what makes growth in services a lever on value, rather than merely an addition to the revenue line.
Alongside it, a further segment was built that did not exist at all in 2011. Apple Watch launched in 2015, AirPods in 2016, and HomePod beside them. The wearables, home and accessories category grew from under $10 billion a year to more than $30 billion.
And the base everything rests on: more than 2.5 billion active devices.
The Second Engine, and the One Least Discussed
In 2012 Apple did two things a growth company did not usually do: it reinstated the dividend, and it began buying back its own shares.
| Since 2012 | |
|---|---|
| Total returned to shareholders | over $1 trillion |
| Of which, buybacks | about $877 billion |
| Consecutive dividend increases | 13 years |
| Returned in fiscal 2025 alone | about $104.7 billion |
And what those figures did to the stock:
Apple's share count fell from about 26 billion in 2013 to roughly 14.6 billion today - a drop of about 44%.
The meaning is simple and powerful: someone who held one share and did nothing at all owns a materially larger slice of the company today. And a given profit is divided across fewer shares, so earnings per share grow faster than earnings themselves.
This is the missing piece in the gap between 3.9x and 14x. Not only did the company grow, and not only did its mix improve - the denominator also shrank.
Apple's return on equity currently stands at about 149%. That is not a figure indicating operational magic alone; it is a direct consequence of a company returning capital at a pace that leaves the equity remaining on the balance sheet small relative to profit.
The Third Engine: The Chips
In 2020 Apple announced it was moving from Intel's processors to processors it designs itself. It was a move that sounded technical and turned out to be strategic.
A company that designs its own chip controls its own schedule, its specification, and a substantial part of its cost. It also stops sharing the margin with a supplier. That is a straight line from an engineering decision to the gross profit line, which currently stands at about 49%.
And What Did Not Happen
A piece on a legacy that presents only that side is not a piece, it is a press release. So here is the other side, as the criticism frames it.
Artificial intelligence. This is the central criticism. The revamped version of Siri was postponed repeatedly, and arrives only now with the new operating system. Along the way Apple had to lean on Google's models rather than its own development. At a time when competitors directed enormous sums to the field, Apple was seen as late.
Dependence on China. The same supply chain that created the efficiency tied the company's fate to a single geography, and that became a political risk. Apple has been diversifying manufacturing in recent years, but the move proceeds from a starting point of high concentration.
The absence of a new category on the scale of the iPhone. Apple Watch and AirPods are large and successful businesses, but neither is a platform that replaces the iPhone. The common criticism is that Cook delivered a series of incremental improvements rather than one breakthrough.
And my reservation about the third criticism is this: a category on the scale of the iPhone is an event that happens once in decades, not a reasonable yardstick for assessing a chief executive. The first criticism, by contrast, concerns something happening now and carrying a timetable.
The Man Coming In
John Ternus joined Apple in 2001, was appointed vice president of hardware engineering in 2013 and senior vice president in that field in 2021. He was responsible for engineering the Mac, iPad, iPhone and Watch, and was involved in developing the iPad and AirPods.
In the official announcement Cook said of him that he has "the mind of an engineer, the soul of an innovator, and the heart to lead with integrity and with honor". Ternus himself said: "Having spent almost my entire career at Apple, I have been lucky to have worked under Steve Jobs and to have had Tim Cook as my mentor."
And board chairman Arthur Levinson said Cook's leadership "has transformed Apple into the world's best company".
And the difference between the two is worth noting: Cook came from operations, Ternus comes from engineering. A company whose central criticism is technological has appointed an engineer.
And What the Stock Did Today
On Ternus's first day in the job Apple traded around $325, up about 2.8% - on a day when the S&P 500 is down around half a percent. Over the trailing twelve months the stock has risen about 41%.
That is a single day's reaction and no conclusions about a period follow from it, but it does say the market did not price the transition as an event of uncertainty.

דעה אישית של אילן אברמוב - לא ייעוץ ולא המלצה
What I take from Cook's period has nothing to do with products, and I think that is also why it is easy to underrate him.
The common account is that Cook was "the operations man who continued Jobs". I think that is an accurate description that misses the main thing. What Cook did was take a company whose value came from the success of individual products, and turn it into a company whose value comes from a system. An installed base of 2.5 billion devices, above it a recurring services stream, and above that a capital-return mechanism that shrinks the share count.
And here sits what I think is the most interesting lesson for a reader of financial statements. The gap between 3.9x in revenue and 14x in value is not a gap of optimism. It is composed of three things you can point at: a mix that shifted toward recurring revenue, a gross margin held high partly through control of the chip, and a share count down 44%.
When I see a company whose value rises much faster than its revenue, that is the first question I ask: which of those three is happening here, and if none of them - then what is. Sometimes the answer is a multiple that expanded with no structural reason, and that is an entirely different story.
As for the legacy itself, I think it will be settled not by what Cook built but by what now happens to his weak side. If Apple closes the gap in artificial intelligence over the coming years, his period will be remembered as having built the base that made it possible. If not, that same base will be remembered as what concealed the delay. That is not a question anyone can settle today, and I would be wary of anyone who settles it.
What I do think can be said with confidence: Cook inherited a company whose question was who would replace the founder, and he hands over a company whose question is technological. Those are two questions of entirely different magnitude.
(It is important to stress: this is my personal opinion only, and nothing herein constitutes a recommendation to take any action.)
