The step-by-step life cycle of an Indian IPO
1. Hiring merchant bankers and drafting the DRHP
The issuing company appoints lead merchant bankers to audit accounts, perform corporate valuation, and prepare the Draft Red Herring Prospectus (DRHP) submitted to SEBI for regulatory review and public scrutiny.
2. SEBI approval and RHP release
Upon addressing SEBI review observations, the final Red Herring Prospectus (RHP) is released, detailing business risks, use of proceeds, financial balance sheets, and management governance without specifying the exact final share price.
3. Price band fixation and roadshows
The promoters and merchant bankers announce the bidding Price Band (for example, ₹290 to ₹305 per share) and conduct institutional investor roadshows to build market demand.
4. Public bidding window (3 to 4 days)
The IPO opens for public subscription. Investors submit bids through their stockbroker (Zerodha, Groww, Angel One) using ASBA via UPI, which freezes the bid amount in the applicant's bank account without debiting it immediately.
5. Basis of allotment and stock exchange listing
If the IPO is oversubscribed, the registrar conducts a randomized computerized lottery for retail allotment. Allotted shares are credited directly to Demat accounts within two working days, blocked bank funds are debited (or unblocked for unsuccessful bidders), and shares ring the opening bell for public trading on BSE and NSE.
