AI summary

The disclosure was filed under Regulation 31 of SEBI's SAST Regulations, 2011.

Likely market impact

This is a modest increase in the promoter's pledged holdings and is not alarming at current levels (under 4% encumbered). Shareholders should watch for any sharp fall in the stock price, which could trigger margin calls or pledge invocation, potentially putting downward pressure on the share. It is a routine fundraising activity by the promoter using their own holdings as collateral.
