AI summary

Smt. Sudha Dattatray Mhaiskar, a promoter of IRB Infrastructure Developers, has created a new pledge of 6,75,000 shares (0.011% of total share capital) in favour of Kotak Securities Limited on March 27, 2025. The pledge was created for a personal borrowing of INR 10 crore, against shares valued at around INR 3.11 crore on the date of the event. After this pledge, the promoter's total encumbered shares stand at 41,45,000 shares. The promoter continues to hold 55.49% of IRB's total share capital, well above the 50% mark.

Likely market impact

This is a small incremental pledge creation by a single promoter for personal borrowing. The pledged amount is minimal relative to total share capital, ownership remains unchanged, and encumbrance level is still below the 50% promoter-holding threshold. No material impact on shareholders expected.
