What Is a Stock Buyback? How Share Repurchases Affect Investors
Companies don't just pay dividends — they also buy back their own shares from the market. This is called a buyback. Here's how it works and what it gives shareholders.
What it is
A buyback is a share repurchase: the company buys its own shares on the market. The repurchased shares are often canceled, so fewer shares remain outstanding. Each remaining shareholder's stake in the company grows.
Example
| Before | After a 10% buyback | |
|---|---|---|
| Shares | 100 million | 90 million |
| Earnings | $1 billion | $1 billion |
| EPS | $10 | ≈ $11.1 |
The earnings are the same, but there's more of them per share.
Buybacks vs. dividends
Both are ways to return money to shareholders. Dividends land in your account, while a buyback works through a larger stake. In some countries, buybacks are more tax-efficient.
The catch
If a company buys back shares with borrowed money or at an inflated price, it can hurt the business. Look at debt and cash flow — see the financial statements lesson.

Frequently asked questions

A buyback creates extra demand, but the price depends on many factors. A rise is not promised.
How do I find out about a buyback?
Companies announce repurchase programs in press releases and reports, including the size and timeframe.
Do I have to sell my shares during a buyback?
No, participation is voluntary. The company buys shares on the market from those who decided to sell.
