Infosys' recent announcement of a ₹18,000 crore buyback has left the stock market buzzing and rightfully so. The blue chip company is set to buy back 1 crore equity shares at ₹1,800 per share, its biggest buyback ever!
But is a share buyback beneficial for an investor? Should you wait out the buyback or book your profits now?
In this blog, you will understand what a stock buyback is, why companies opt for it, and its pros and cons for investors.
A share buyback, also known as stock repurchase, is a corporate action where companies buy back their shares from existing shareholders at a premium price. The shareholders are given the choice to either hold their shares or sell them to the company for a profit.
Companies buy back shares with accumulated profits. They choose to pay shareholders instead of investing in the business. It could be a sign that there is no new business opportunity or a sign of confidence in the company’s growth.
Further, the amount of shares bought back is minuscule compared to the total shares issued. In the case of Infosys' share buyback, it is buying back 1 crore out of over 400 crore outstanding shares. Hence, the buyback is unlikely to have any material impact on the share price.
But why would an investor sell their shares back to the company, and what benefit will they get?
To persuade investors to sell their shares, the company sets the share buyback price higher than the current market price (CMP) of the stock. The additional amount above the CMP of the share is called the “premium”.
There are multiple reasons why companies opt for share buyback:
When a company raises capital by issuing shares, it dilutes its controlling power over the company. A buyback helps the company strengthen its controlling interest.
As a buyback decreases the number of shares issued while keeping the profits consistent, it increases the EPS (earnings per share) ratio of the company. This improves the company’s financials and boosts the confidence of existing investors.
If a company’s stock is significantly undervalued, it may opt for a share buyback, resulting in a considerable reduction in shares available in the market, which bumps up the share price.
Alternatively, in case of undervalued shares, if the company is confident in its growth and believes the share price will rise, it buys back shares and reissues them later in the future when they reflect their true value.
There are two methods of share buyback:
In an open market method, the company buys back its shares directly from the stock market over a period of time.
In a tender offer, the company offers the existing shareholders the choice to sell their shares to the company at a premium price that is higher than the share’s CMP within a specified period.
Here’s how you can participate in a share buyback
Contact the company or your stockbroker and apply with the number of unpledged shares you’re willing to sell.
Generally, the company will accept all your shares if the buyback is not oversubscribed. In case of an oversubscribed buyback, the company accepts shares on a pro-rata basis.
Once the company accepts your shares, you will get payment in the form of cash in exchange for the shares.
Whether to hold or sell will be your personal choice based on your perspective and circumstances. But let’s walk through both options so you can make a practical decision.
If you have been considering selling your shares for liquidity purposes, then a stock buyback is the right decision. You get a premium price for the shares, and the company gets to buy back shares, making it a win-win situation.
Earlier, the company opting for a share buyback was liable to pay the taxes, but after the new tax rule effective from October 1, 2024, the amount received by the shareholders in a buyback is taxable as “income from other sources” as per the tax rate application.
As mentioned above, a stock buyback can potentially increase the company’s share price and improve its financial strength and performance.
Depending on the company, if you prefer to hold your shares, you could face liquidity issues in the future, as the number of shares traded and the trading volume will decrease substantially.
If the buyback is done to boost the share price temporarily and does not signal a strong financial health of the company, then the share price might fall. To counter this, use fundamental analysis to decide whether to hold or sell.
