Can IPO subscription be cancelled?

For investors,

• An IPO application in the retail category may be cancelled by the investor at any time prior to the closing date of the offering.
• An IPO application in the NII and QIB categories cannot be withdrawn. The bid price modification (upsize) is possible as long as the issue is still open.

For companies,

If an IPO isn't fully subscribed or doesn't meet the minimum subscription criteria, the company may extend the deadline for closing the offering or reduce the OFS size. If this doesn't succeed, or if the company decides to cancel the IPO for other reasons, it may do so at any time.
