IPO Price Band is the price range within which investors can bid for the shares. The minimum price is called the floor price and the maximum price is called the cap price.
In case the company revises the price band, the offer period gets extended for at least three additional working days.
Any revision in the price band and the revised offer period, if applicable, is shared by notification to the stock exchanges by issuing a press release and on the websites of the book running lead managers.
