What is Share Buyback?

Explanation of a share buyback

A share buyback, also known as a share repurchase, occurs when a company buys back shares that were previously issued to shareholders. This can be done for several strategic reasons, including returning capital to shareholders, adjusting the company’s capital structure, or providing liquidity to shareholders who wish to exit their investment.

In private companies, share buybacks are often used as a mechanism to facilitate shareholder exits, ownership restructuring, or succession planning. The company typically purchases the shares directly from the shareholder using company funds, subject to legal and regulatory requirements.

In the UK, share buybacks are governed primarily by provisions within the Companies Act. Companies must follow specific legal procedures, including obtaining shareholder approval and ensuring the transaction is carried out from distributable profits or permitted capital sources.

The outcome of a share buyback may include cancellation of the repurchased shares or holding them as treasury shares. This reduces the number of shares in issue and can change the proportion of ownership held by the remaining shareholders.

Key characteristics of a share buyback

Key characteristics of a share buyback include:

• It involves a company repurchasing shares from existing shareholders.
• The number of shares in circulation typically decreases following the transaction.
• Share buybacks may be used to facilitate shareholder exits or restructure ownership.
• The transaction is governed by company law and the company’s constitutional documents.
• Shares repurchased by the company may be cancelled or held in treasury.
• Buybacks are common in both listed and privately owned companies.

How a share buyback works

A share buyback typically follows a structured legal and financial process:

• The company identifies the purpose and structure of the share buyback.
• Shareholder approval is obtained in accordance with the Companies Act and the company’s articles of association.
• The company agrees a purchase price with the selling shareholder.
• The company completes the transaction and either cancels the shares or holds them as treasury shares.

Example of a share buyback in practice

A founding shareholder of a UK private company plans to retire and sell their shares. Rather than selling to an external buyer, the company repurchases the shares directly using distributable profits. The shares are cancelled after the transaction, increasing the ownership percentage of the remaining shareholders.
