AI summary

Promoter Smt. Sudha Dattatray Mhaiskar has created a pledge on 2,00,000 shares (0.003% of total share capital) of IRB Infrastructure Developers in favour of Kotak Securities Limited on August 29, 2025. The pledge was raised for personal borrowing of ₹10 crore. After this pledge, her total encumbered shares stand at 50,45,000 (0.084% of total share capital), which represents nearly all of her individual promoter holding of 50,59,080 shares. The total promoter group shareholding in the company remains at 1,83,70,55,980 shares (30.42% of total share capital).

Likely market impact

This is a routine pledge creation by a promoter for personal borrowing against shares. Since the pledged shares belong to a single promoter and represent only 0.003% of total share capital, this is unlikely to materially affect the stock price. However, it brings her individual pledged holding to nearly 100% of her personal stake, which investors may note as a signal of leverage at the promoter level.
