Apple's Record-Breaking Stock Buybacks Under Tim Cook: A Boost to Shareholders?

Under Tim Cook's leadership, Apple has implemented one of its largest-ever stock buyback programs. The program started with a $10 billion authorization in 2013 and was later raised to $60 billion, making it the largest single share-repurchase authorization in history. In 2018, Apple authorized repurchases of $100 billion, followed by another $110 billion in 2024, which remains its largest-ever buyback. The company has also bought back a whopping $877 billion in shares under Cook's leadership.

Apple normally uses most of its authorized buybacks and retires the shares afterwards. This means that with fewer shares in circulation, every shareholder owns a larger slice of the company. Although this change is relatively minor over a quarter or year, it makes a significant difference for long-term investors. When Cook took over, Apple had about 26 billion split-adjusted outstanding shares, which has fallen by about 44% to around 14.6 billion as of July 2026.

The share count decrease means that a shareholder who purchased a share at the start of Cook's tenure now owns nearly 80% more than they did then. However, it is worth noting that Apple's valuation has risen significantly since the early days of its buyback program, trading at around 36 times trailing earnings as of this writing. Buying back shares at a higher valuation means less added value for shareholders.
