What is a stock buyback?
In one line: A buyback, or share repurchase, is when a company uses its cash to buy back its own shares from the market, reducing the number of shares out there.
A simple example
Say a company earns $100 million a year in Net income and has 100 million shares.
- Earnings per share (EPS) = $100M ÷ 100M = $1.00.
Now it buys back 10 million shares. There are 90 million left. Profit stays the same.
- New EPS = $100M ÷ 90M = about $1.11.
Each remaining share now owns a slightly bigger slice of the company. The business didn't change. The slices just got bigger.
Why companies do it
- To return cash to shareholders, as another way besides a Dividend.
- Because they think the stock is cheap. Buying shares below their worth can benefit those who stay.
- To offset new shares given to employees as pay, so the share count doesn't creep up.
Buybacks are usually paid for with Free cash flow, and sometimes with borrowed money. Since 2023, US companies pay a 1% federal excise tax on the value of shares they buy back.
Why it matters for traders
A big buyback announcement can lift a stock, since the company becomes a steady buyer. But an announcement is a plan, not a promise. Companies can buy slowly, or not at all.
A common mistake
Thinking EPS growth from buybacks means the business is growing. In the example, EPS rose 11% while profit didn't change at all. Check Revenue and net income too, to see if the business itself is getting bigger.
A buyback at a high price can destroy value, just like overpaying for anything. Buybacks funded with heavy debt add risk too.
Questions
Is a stock buyback good for shareholders?
It can be, if the company has spare cash and buys at a sensible price. It can be bad if it overpays or borrows heavily.
Buyback or dividend: what's the difference?
A dividend pays cash to every shareholder. A buyback pays cash to those who sell, while those who keep their shares own a bigger slice.
Do buybacks raise the stock price?
They add a buyer and raise EPS, which can support the price. They don't guarantee it goes up.
