How share buybacks change what you own

When a company repurchases its own shares, those shares are cancelled or held in treasury. The business is worth slightly less afterwards, because cash has left it, but each remaining share represents a larger slice of what is left. Shareholders who do not sell end up owning more of the company without buying anything.

The per-share illusion

Because earnings per share divides profit by share count, a buyback can lift EPS while profit is flat or falling. That is arithmetic, not performance. Analysts separate the two by looking at total net income and free cash flow alongside the per-share figures.

Price paid is the whole question

A repurchase at a price below intrinsic value transfers value from sellers to holders. Above it, the transfer runs the other way. This is why the timing pattern matters: companies that buy heavily at cyclical peaks and stop during downturns have systematically destroyed value, whatever the announcement said.

• Funded from surplus cash: a genuine return of capital.
• Funded by borrowing: leverage rises and future flexibility falls.
• Offsetting share issuance to staff: not a return of capital at all, but a cost.

Dividends compared

A dividend pays every holder in cash and is taxed on receipt in most jurisdictions. A buyback pays only those who sell and converts the benefit into a capital gain for the rest. The choice between them is partly tax policy, partly a signal about how confident management is that the payment can be sustained.
