A share buyback, or repurchase, happens when a company buys its own shares from the market, reducing the number of shares outstanding. Buybacks are a major way companies return cash to shareholders; S&P 500 companies have spent several hundred billion dollars a year on buybacks, exceeding $900 billion in some recent years according to S&P Dow Jones Indices. Buybacks can create value when shares are cheap, but they can also destroy value when done at high prices or funded with excessive debt.

## How buybacks work

| Method | Description |
|---|---|
| Open market repurchases | The company buys shares gradually through brokers; most common |
| Tender offer | The company offers to buy a set number of shares at a fixed price or range, usually at a premium |
| Accelerated share repurchase (ASR) | A bank delivers shares upfront and buys them in the market over time |
| Dutch auction tender | Shareholders bid prices; the company buys at the lowest price that fills the target |

Repurchased shares are usually held as treasury stock or cancelled.

## Effect on per share figures

Fewer shares mean each remaining share owns a bigger slice of the company.

**Example: Buybacks and EPS**
A company earns $1 billion with 500 million shares (EPS $2.00) and trades at $40 (P/E 20). It spends $2 billion buying back shares at $40, retiring 50 million shares.

- New share count: 450 million.
- If earnings stay at $1 billion (ignoring the lost interest on cash spent), EPS rises to about $2.22, an 11% increase.
- Each shareholder's ownership rises by about 11%.

If the company had paid the $2 billion out as a dividend instead, shareholders would have received $4 per share in cash. Which is better depends on the share price relative to value and on taxes. See [Dividends](https://learn.tradelabsai.com/fundamentals/dividends/).

## When buybacks create value

- **Shares are below intrinsic value:** the company buys a dollar of value for less than a dollar.
- **The company has no better high return investments.** See [Capital Allocation and Management](https://learn.tradelabsai.com/fundamentals/capital-allocation/).
- **The balance sheet stays strong.**
- **Buybacks reduce share count** rather than just offsetting stock compensation.

## When buybacks destroy value

- **Buying at peak prices,** then issuing shares cheaply in downturns.
- **Funding with excessive debt,** weakening the balance sheet before a recession.
- **Offsetting dilution only:** heavy stock compensation can mean large buybacks with no fall in share count.
- **Managing EPS targets** to hit executive pay goals.

Before the 2008 crisis and in 2019, many companies, including airlines and banks, spent heavily on buybacks and then needed capital in downturns, drawing criticism.

## Buybacks vs dividends

| | Buybacks | Dividends |
|---|---|---|
| Flexibility | Can be paused easily | Cuts are seen as bad signals |
| Taxes | Shareholders taxed only when they sell (in many places) | Taxed when received |
| Signal | Management thinks shares are cheap (if timed well) | Confidence in steady cash flow |
| Who benefits | Remaining holders get a bigger share | All holders get cash |

Since 2023, the US has imposed a 1% excise tax on net share repurchases by public companies.

## The evidence

Studies such as Ikenberry, Lakonishok and Vermaelen (1995) found that companies announcing buybacks tended to outperform over the following years, especially value stocks. More recent research suggests the effect has weakened as buybacks became routine. Companies that consistently reduce share count, a "net payout yield", have been a focus of some quantitative strategies.

## Buybacks in crypto

Some crypto protocols use revenue to buy back their own tokens, a similar mechanism for returning value to token holders. See [Tokenomics and Protocol Revenue](https://learn.tradelabsai.com/crypto/tokenomics-and-protocol-revenue/).

## Frequently asked questions

### What is a stock buyback?

When a company repurchases its own shares from the market, reducing the number of shares outstanding.

### Do buybacks increase stock prices?

They increase each share's claim on earnings and can support prices, but they create value only if done at prices below intrinsic value.

### Why are buybacks controversial?

Critics argue some companies buy back shares at high prices, use debt to fund them or use them to meet pay targets, leaving them weaker in downturns.
