Share Buyback
A share buyback is a company's purchase of its own shares — on the market over time, by a tender offer, or from a specific holder — which are cancelled or held in treasury, so the remaining shares represent a larger slice of the same business. It returns cash without a dividend, raises earnings per share by shrinking the denominator, and is what a company does with capital it cannot invest above its cost.
- Also known as
- Buyback, Share repurchase, Stock repurchase
- Used at
- listed companies with surplus cash and no better use; private companies buying out a departing founder or an investor; fintechs after a down round, buying back employee shares
- Binding
- shareholder authority (in most jurisdictions a general authority for up to 10–15% of the capital), board resolution, and for banks and licensed firms the regulator's consent, since a buyback reduces capital
- Typical scale
- US listed companies returned more through buybacks than dividends in most years since 2010; a "€200m programme over twelve months" is the usual form
- Typical effect
- earnings per share rise by roughly the percentage of shares bought (net of the interest lost on the cash); value is created only if the shares were bought below their worth, and destroyed if above
- Parties
- the company and its board, the selling shareholders, the remaining shareholders (who now own more), the broker executing on-market, and the regulator for a licensed firm
How a share buyback works in practice
A listed payments company earns €300m, has €800m of cash it does not need and sees no acquisition worth the price. It announces a €400m buyback over a year. Its broker buys shares on the market within daily limits and outside close periods; the shares are cancelled; at the end the company has 4% fewer shares, and the same earnings are €3.13 a share instead of €3.00. Shareholders who sold received cash; those who stayed own more of the company. Compared with a dividend, the buyback is flexible — it can be paused — and it favours those who stay over those who leave.
Whether it created value depends on the price. Buying shares at €40 that are worth €50 transfers €10 a share from the sellers to the remaining holders; buying at €60 does the reverse. Boards that buy back at the top of the cycle to "support the price" or to offset option dilution destroy value with the shareholders' own money, and the accounting rise in earnings per share hides it. The honest test is the one an acquisition faces: is this the best return available for the capital.
For a bank or a licensed fintech a buyback is a capital reduction, and the regulator consents or not: a bank above its requirements with no growth to fund buys back; one near them does not, whatever its share price.
Example
A listed lending fintech with 100m shares at €25, €150m of earnings (€1.50 a share) and €500m of surplus capital considers a €250m buyback or an acquisition of a competitor for the same money. The buyback retires 10m shares at €25: earnings per share rise to €1.67, an 11% increase, and the company's own valuation work says the shares are worth €32 — so the buyback transfers about €70m of value to the remaining holders. The acquisition would add €18m of earnings for €250m — a 7.2% earnings yield against the buyback's effective 6.7% (€1.50 ÷ €25 grossed up for the cheap price) — but at a price 14× earnings, with integration risk and a regulator's review. The board buys back €150m and keeps €100m for a smaller deal. Its regulator, which had asked for a capital plan, agrees because the CET1 ratio stays above the requirement plus buffers.
Common mistakes
- Buying back to raise earnings per share regardless of the price, and destroying value in the process. - Announcing a programme to "support the share price", which the market reads as a lack of ideas. - Offsetting employee option dilution with buybacks at the top of the cycle. - A licensed firm announcing a buyback before asking the regulator. - Choosing a buyback over an acquisition — or the reverse — without comparing the return on the same capital.
