What are Share Buybacks?
Share buybacks are a financial tool used by companies to support their share price by reducing the amount of issued capital in the market. The basic economics determine that, with consistent demand, a reduction in the supply of shares will cause the market price to increase.

Purpose of Share Buybacks
It should be determined whether the shares bought back by the company
are to be cancelled or redistributed. Shares may be bought back for redistribution to
employees, usually through option schemes, or other existing shareholders. In this case the
shares are usually held ‘in Treasury’ by the company for redistribution. In this case the
number of shares outstanding remains unchanged by the share buyback. Where shares bought
back are cancelled, there is a decrease in the number of shares outstanding. Share buybacks
result in a leverage effect where each existing shareholder owns a larger share of the
capital and therefore sees an increased share of profits redistributed through dividends.
All other things being equal, this effect increases the price of the stock. The number of
shares is reduced and each remaining shares has more value.
Advantages and Disadvantages
Advantages
- Share buybacks increase share prices by reducing the supply of shares in the market
- Buybacks are a means of returning cash to existing shareholders in form of share-price gains
- The earnings and profitability ratios per share increase, since profit remains constant divided by a decreased amount of outstanding shares
- EPS (Earnings Per Share) increases, making the company appear more profitable to investors
- Provides flexibility compared to dividends which create ongoing expectations
Disadvantages
- Reduced access to capital since available cash is spent to buyback shares
- Reduced retained earnings or reserves
- Less room to maneuver through a reduction in available cash for new projects or to withstand challenging market conditions
- After a share buyback, there is a shortage of available funds for future investments
- May signal that the company lacks better investment opportunities for growth
Share Buybacks in comparison with dividends
Share buybacks and dividends are both means of returning capital to
shareholders. In the case of dividends, the return is distributed amongst all the
shareholders proportionately. In the case of share buybacks the company is buying shares
from existing shareholders, so the number of shareholders is reduced, or at least the number
of shares owned by some is reduced. There is a quiescent reward for remaining shareholders
which is an increased interest (stake) in the company even though the number of shares they
own is unchanged.
Investors typically look at the headline yield offered by a stock when considering whether
to invest. The yield being the amount of dividends paid out relative to the share price.
However, the number of shares bought back and likely future buybacks will equally affect the
share price and thereby the profitability of investing. As such investors should be aware of
a company’s buyback history and future plans where possible, not just the dividend policy.
Conclusion
In order to properly assess a company’s financial position investors need
to consider recent share buybacks and share buyback plans for two reasons: The first is the
use of cash for buybacks which affects free cash available for other purposes, thereby
affecting financial performance. The second is the direct affect on the share price – the
reduced number of shares on issue will increase the price, all other things being equal.
Assessing historic and recent share buybacks can provide a guide but most companies also
announce their buyback plans ahead, making future share buybacks more predictable though
never certain.
