# What Is Share Buyback?

> A share buyback is when a company repurchases its own stock from shareholders — reducing shares outstanding and returning capital to sellers, sometimes used for employee liquidity or cap table cleanup.

A **share buyback** uses company cash (or debt) to repurchase equity from existing shareholders rather than raising new primary capital.

## How it works

The board authorizes a repurchase program with price, eligibility, and size caps. In private companies, buybacks often appear as **tender offers** — employees and early investors sell into a fixed pool at a set price. Public companies announce open-market or accelerated repurchases, often when management believes stock is undervalued.

Repurchased shares may retire (reducing dilution) or sit in treasury. Buybacks differ from [secondary sales](/glossary/secondary-sale) funded by outside buyers — here the company is the buyer.

Tax, securities law, and charter restrictions apply; preferred consent may be required if common is bought while preferred remains outstanding.

## Why it matters

- **Founders:** Buybacks can reward long-tenured employees without a full secondary round — but spending scarce cash has opportunity cost vs R&D and GTM.
- **Investors:** They evaluate fairness (pro rata access), signaling (exit delay?), and impact on runway and valuation marks.

## Common mistake

Running a buyback that only executives can access — other shareholders and employees treat it as a governance red flag.

## FAQ

### What is Share Buyback in simple terms?

The company uses cash to buy shares back from owners — employees, founders, or investors — instead of issuing new stock. Outstanding share count drops; sellers get liquidity.

### Why does Share Buyback matter?

Buybacks can provide structured liquidity without new investors on the cap table. Investors watch whether buybacks favor insiders, drain growth capital, or signal lack of better investment opportunities.
