# What Is a Bonus Issue?

A bonus issue is when a company distributes additional shares to eligible existing shareholders by capitalising eligible reserves, subject to applicable rules. The number of shares increases, but the market price per share generally adjusts.

Example: 1:1 bonus issue

Suppose you own 100 shares priced at ₹500 each, worth ₹50,000. In a 1:1 bonus issue, you receive one additional share for every share held.

| Measure | Before | Theoretical after adjustment |

|---|---:|---:|

| Shares held | 100 | 200 |

| Price per share | ₹500 | ₹250 |

| Holding value | ₹50,000 | ₹50,000 |

This illustration ignores market movements. The actual price may rise or fall after the event.

Why might a company issue bonus shares?

•Capitalise eligible reserves.
•Increase the number of shares in circulation.
•Reduce the nominal price per share.
•Signal management confidence, though the action alone does not prove strong fundamentals.

Bonus issue vs stock split

A bonus issue creates additional shares from eligible reserves under the applicable corporate-action framework. A stock split subdivides existing shares. Both generally reduce the theoretical per-share price and neither automatically increases total economic value.

What investors should evaluate

Review revenue growth, profitability, free cash flow, debt, return on capital, and valuation. Confirm the ratio, record date, and eligibility from the company's official filing.

Key takeaway

More shares do not automatically mean more wealth. The business and market value matter more than the share count alone.

FAQs

Are bonus shares free?

No additional purchase payment is generally required to receive eligible shares, but the per-share price usually adjusts. The action does not create extra value by itself.

Does a bonus issue improve EPS?

The share count used in EPS calculations changes, and per-share figures may be adjusted under accounting standards. The bonus issue itself does not increase total earnings.

Should I buy before a bonus issue?

Do not invest solely to receive bonus shares. Consider fundamentals, valuation, risks, and your objectives.
