When Tim Cook became CEO of Apple (AAPL -0.63%) in 2011, one of his biggest strategic shifts was returning capital to shareholders. He reinstated the company's dividend in 2012 and, more importantly, launched a massive stock buyback program.
Apple has spent more than any other company on stock buybacks over the last 10 years, according to research by The Motley Fool. Here's a closer look at how much it has spent and why this benefits shareholders.

Apple's stock buybacks during Tim Cook's tenure
Cook has been part of multiple record-breaking share buybacks while CEO of Apple. Near the beginning of his tenure, the board authorized a $10 billion buyback for its fiscal 2013, but later raised that to $60 billion, the largest single share-repurchase authorization in history. It authorized repurchases of $100 billion in 2018 and $110 billion in 2024, with the latter still being its largest-ever buyback. In 2025 and 2026, it authorized $100 billion in buybacks.
A buyback authorization only means a company can spend up to that amount, not that it will. Apple normally uses most of it, though, and has bought back a whopping $877 billion in shares under Cook's leadership.
A (mostly) positive move for Apple shareholders
After Apple buys back shares, it retires them. With fewer shares in circulation, every shareholder owns a larger slice of the company. Over a quarter or even a year, this is a relatively minor change. At Apple's market cap of $4.6 trillion (as of Aug. 19), a $100 billion repurchase authorization means buying back a little over 2% of the company.
But for a long-term investor, it makes a significant difference. Case in point, when Cook took over, Apple had about 26 billion split-adjusted outstanding shares. It reported 14.6 billion outstanding shares as of July 2026, so the share count has fallen by about 44%. A share purchased at the start of Cook's tenure now owns nearly 80% more than it did then.

Key Data Points
The caveat here is that Apple's valuation has risen significantly since the early days of its buyback program. It traded between 12 and 18 times earnings for much of the 2010s. It trades at 36 times trailing earnings as of this writing, while Apple and other top tech stocks have seen considerable price appreciation. Buying back shares at a higher valuation means less added value for shareholders.
Apple's repurchase program was a major tailwind for most of Cook's tenure. However, John Ternus will become the company's new CEO on Sept. 1, 2026, and the leadership transition could also signal a shift in strategy. Buybacks will remain part of Apple's approach, but the company may divert some of that capital to research and development or building through acquisitions. Given Apple's somewhat expensive valuation, either could prove a better growth driver than buying back shares.
