To analyze the impact of share repurchases on earnings per share (EPS), you simply divide the company's net profit by the reduced number of outstanding shares after the buyback. Since share repurchases reduce the total shares in the market, they usually increase the EPS, even if the net profit stays the same. This can make the company look more profitable on a per-share basis.

What Is a Share Buyback and Why Do Companies Do It?

A share buyback, or share repurchase, is when a company buys back its own shares from the market. This reduces the number of shares available to the public. Companies do this to return surplus cash to shareholders, increase EPS, boost shareholder value, or signal confidence in their financial health.

How Do Share Buybacks Increase Earnings Per Share (EPS)?

EPS is calculated as Net Profit ÷ Number of Outstanding Shares. When a company reduces its outstanding shares through a buyback but maintains the same profit, the EPS automatically goes up. This creates the appearance of improved profitability, even if the business hasn't earned more money.

How Can You Calculate the New EPS After a Share Buyback?

To calculate the new EPS after a buyback:

Step 1: Note the company's net profit.
Step 2: Subtract the repurchased shares from the total outstanding shares.
Step 3: Divide the profit by the new number of shares.

For example, if a company earns ₹100 crore and had 10 crore shares, EPS = ₹10. After buying back 1 crore shares, EPS = ₹100 crore ÷ 9 crore = ₹11.11.

Does a Higher EPS Always Mean Better Performance?

No, not always. A higher EPS caused by a buyback might not reflect actual growth in profits. It could just be financial engineering. It’s important to look at total net profit and revenue growth too. Check if the company is genuinely performing better or just improving EPS by reducing shares.

What Are the Risks of Relying on Buybacks to Boost EPS?

Relying on buybacks can be risky. If a company spends too much cash on buying its shares instead of investing in business growth, it can hurt future earnings. Also, if buybacks are used only to boost stock prices in the short term, long-term investors may lose out. Always check the intent behind a buyback.

How Can Investors Use EPS and Buyback Analysis to Make Decisions?

Investors should compare the EPS growth with profit and revenue trends. If EPS is rising because of real business performance, that’s a good sign. But if it’s only rising due to buybacks, you need to be cautious. Also, check if the company is using excess cash wisely or just manipulating stock value. Smart analysis can help you avoid overvalued stocks.
