Investors have shown strong demand, with 54.96 crore shares being bid for out of the 59.31 crore shares on offer.

Retail Individual Investors (RIIs) have subscribed 2.38 times their portion, while the non-institutional investors (NIIs) segment has seen a 34 percent subscription.

The Qualified Institutional Buyers (QIB) category has recorded a 75 percent subscription.
