When a company adjusts the number of its outstanding shares, it may undertake a stock split or a reverse stock split, also known as a stock merger. These actions change the number of shares and their per-share price without altering the company’s overall market capitalisation or the value of an investor’s holdings. Below, we explain what stock splits and mergers are, why companies pursue them, and how they impact investors.
Key Highlights:
- A stock split increases the number of shares and decreases the price of the shares without altering the company’s net worth.
- A reverse stock split decreases the number of shares and increases the price of the shares without affecting the company’s net worth.
- Both increase or decrease the number of shares and the price of the shares proportionately but do not alter the market capitalisation of the company or the value of the investors’ investment immediately.
A stock split is a method of corporate restructuring during which a company increases its number of outstanding shares by splitting its existing shares into numerous shares. Although the number of shares increases, there is no change in the total value of the investment.
Example: You have 100 shares of a particular company whose current share price is ₹1,000.
Your total investment is: 100 × ₹1,000 = ₹1,00,000
After that, the company announces a 2-for-1 stock split.
Now you have 100 shares = 200 shares, Price of a share reduces from ₹1,000 to ₹500
The value of your investment is now: 200 × ₹500 = ₹1,00,000
So even though the number of shares has increased twofold, the total value of the investments remains the same.
The purpose of stock splitting by companies is to reduce the price of their shares without affecting the overall market value of the business organisation. A reduced share price can help in attracting more investors in the business.
Example: A business firm's stock is available at ₹5,000 per share. It declares a 5-for-1 stock split, which reduces the cost of the stock to ₹1,000. The company increases the number of shares by five times.
A stock split will not directly increase an investor’s wealth, but it provides certain benefits to shareholders. The stock split achieves this by reducing the share price and increasing the number of shares outstanding, thus improving the stock's liquidity and marketability.
A reverse stock split is also called a stock split or stock consolidation and is a corporate event in which a company combines several equity shares into one. With fewer shares available, the market price rises accordingly, even though the company's market capitalisation and the value of investors’ holdings remain unchanged.
Example: If you have 100 shares of a stock and the price per share is ₹50, then your total investment is: 100 × ₹50 = ₹5,000
The company now announces a reverse stock split in which 1 stock will be merged into 5.
So, if you have 100 stocks, you will now have only 20 stocks.
Also, the price of each stock will be increased to ₹250 to account for the merger.
After the stock split: 20 × ₹250 = ₹5,000
So, even right after the merger has taken place, the total value of your investment remains the same even if you have fewer shares at a higher price per share of the stock.
A reverse stock split helps the company satisfy exchange listing requirements. In other words, it helps keep a stock's share price from falling below the minimum price required by a stock exchange.
A reverse stock split does not change the total value of an investor's holdings immediately. It reduces the number of shares while increasing the share price in the same proportion. However, it can have several practical implications for investors.
A stock split or a reverse split does not affect the market value of the firm or the total value of the investor’s holdings immediately. Likewise, such repartitions do not result in any tax consequences at the moment of their realisation.
| Basis | Stock Split | Reverse Stock Split | Taxation |
| Meaning | Increases the number of shares by dividing existing shares. | Reduces the number of shares by merging existing shares. | No tax is triggered merely because of a stock split or reverse stock split. |
| Share Price | Decreases proportionately. | Increases proportionately. | The adjusted share price is used to calculate capital gains when the shares are sold. |
| Number of Shares | Shares Increases | Shares Decreases | The revised number of shares becomes the basis for future tax calculations. |
| Investment Value | Remains unchanged immediately after the split. | Remains unchanged immediately after the split. | Tax is payable only when the shares are sold, and a capital gain arises. |
| Purpose | Improves affordability and liquidity. | Raises a low share price and helps meet listing requirements. | Ensures capital gains are calculated based on the adjusted cost of acquisition and shareholding. |
| Capital Gains Tax | Not applicable at the time of the split. | Not applicable at the time of the reverse split. | Short-term or long-term capital gains tax applies only when the shares are sold, as per the applicable tax rules. |
In deciding whether to invest in a stock following a stock split or reverse stock split, it is important to note that these corporate actions do not impact the intrinsic value of the business. Rather, investors should consider the company's fundamentals.
Stock splits and reverse stock splits are corporate decisions aimed at modifying the number of shares and share prices without influencing market capitalisation or the value of investments made. Though stock splits might make it easier for individuals to invest in stocks, reverse stock splits might indicate problems in the company that need to be evaluated.
