Apple Announced Its Largest-Ever Stock Buyback Under Tim Cook's Leadership. Here's Why the Size of the Repurchase Program Matters for Shareholders.

Tim Cook became CEO of Apple in 2011 and initiated a significant shift in strategy by returning capital to shareholders. He reintroduced a dividend and established a substantial stock buyback program. Apple's buybacks have been the most expensive of any company over the past decade, as documented by The Motley Fool. Cook has overseen multiple record-breaking buybacks, with the largest being $110 billion in 2024—its highest-ever. Under his leadership, Apple has repurchased $877 billion worth of shares.

When shares are bought back, they are retired, reducing the number of outstanding shares. This dilutes the supply, leading to a larger ownership stake for existing shareholders. For instance, Apple's share count has decreased by approximately 44% since Cook took over, meaning each share now represents slightly more than 80% of what it did initially.

However, Apple's market cap remains impressively high at $4.6 trillion as of August 19, 2026. Consequently, a $100 billion buyback authorization translates to about 2% of the company.

Despite the significant value from buybacks, the company's valuation has surged, trading at 36 times earnings recently, up from a range of 12 to 18 during the 2010s. This higher valuation reduces the net value added to shareholders. With John Ternus set to take over as CEO on September 1, 2026, there may be a shift in strategy, potentially reallocating some capital towards research and development or acquisitions.

While buybacks have been beneficial, the new leadership might steer Apple towards different growth avenues. Investors should weigh these factors when considering Apple as a stock option, keeping in mind that it wasn't included in The Motley Fool's recent top 10 list for long-term growth potential.
