If you looked at your portfolio this morning and saw IRB Infrastructure Developers trading at nearly half its Friday value, there is no need to panic. The stock’s decline from ₹40.93 to a low of ₹20.10 is a purely technical adjustment due to the company’s 1:1 bonus issue, not a loss in actual market value.

In fact, the stock showed strong underlying demand today, rebounding over 11%from its opening price to trade around ₹22.70.
The 1:1 Bonus Explained
A bonus issue is essentially a way for a company to reward shareholders by giving them free additional shares.
-
The Ratio: For every 1 share you held as of the record date, you will receive 1 additional share for free.
-
The Math: Because the number of shares in the market has doubled, the price per share is mathematically halved to keep the company’s total market capitalization (₹26,813 crore) the same.
-
Your Portfolio: If you had 100 shares at ₹40, you will soon have 200 shares at ₹20. Your total investment value remains unchanged.
Key Dates for Shareholders
Understanding the timeline is critical for tracking when your new shares will arrive:
| Event | Date | Impact |
| Ex-Bonus Date | March 30, 2026 (Today) | The price adjusts downward; new buyers from today onwards do not get the bonus. |
| Record Date | April 1, 2026 | The date IRB finalizes the list of eligible shareholders. |
| Credit of Shares | Approx. 10-15 days | Bonus shares will be credited directly to your Demat account. |
Why is the Stock Gaining Today?
Despite the “optical” price drop, investor sentiment remains bullish.

-
Increased Liquidity: By bringing the share price down to the ₹20 range, the stock becomes more accessible to retail investors, often leading to higher trading volumes.
-
Infrastructure Push: With the Noida International Airport (DXN) inauguration and ongoing highway projects in the 2026 fiscal year, IRB is positioned as a primary beneficiary of India’s transport expansion.
-
Historical Context: This is the company’s first-ever bonus issue, following a 10-for-1 stock split back in February 2023, signaling management’s confidence in long-term growth.
Investigative Insight: The “T+1” Settlement Factor
Under the current T+1 settlement cycle in India, you must have purchased the shares by Friday, March 27, to be eligible for this bonus. If you bought shares today (March 30), you are buying them at the “Ex-Bonus” price, meaning you will own the shares at the lower rate but will not receive the free additional shares from the company. Consequently, the 11% rise today indicates that “fresh” buyers are entering the stock at this new, lower entry point, viewing the adjusted price as a bargain.
