The National Stock Exchange places specific securities under Long Term Additional Surveillance Measure based on set criteria. Members must apply a one hundred percent margin rate from September 28, 2026, on all open positions as on September 25, 2026, and on new positions created from September 28, 2026. Securities qualifying under criteria seven shift from the Rolling Settlement segment to the Trade-for-Trade segment from September 28, 2026. This surveillance measure applies alongside other prevailing exchange measures. The shortlisting is a market surveillance action and is not an adverse action against the company.
