IPO Basics
Foundational principles, issue structures, statutory offer documents, and price discovery mechanisms governing public capital offerings in India.
What is an IPO?
An Initial Public Offering (IPO) is the institutional process by which an unlisted private corporation sells its equity shares to public investors for the very first time. By listing on the NSE (National Stock Exchange) or BSE (Bombay Stock Exchange), the enterprise transforms into a publicly held, transparent corporation.
- Raise debt-free long-term capital for capex, technology, and working capital.
- Provide partial or full liquidity to early venture capital, private equity, and founders.
- Unlock public market valuation multiple and create an M&A currency.
- Enhance institutional credibility with banks, enterprise clients, and vendors.
How Does an IPO Work?
An IPO follows a strictly regulated, milestone-driven lifecycle mandated by SEBI and the stock exchanges:
Mainboard vs SME IPO
India's capital markets provide two distinct listing destinations calibrated to corporate maturity:
Fresh Issue vs OFS (Offer for Sale)
An IPO issue can consist of fresh equity, secondary stake sales, or a blend of both:
What is DRHP (Draft Red Herring Prospectus)?
The Draft Red Herring Prospectus (DRHP) is the comprehensive initial disclosure document filed with SEBI and the stock exchanges. It is made public for a minimum of 21 days to invite public comments and regulatory scrutiny.
- Comprehensive Risk Factors (Internal operational risks & external macro risks).
- Objects of the Issue (itemized use of Fresh Issue proceeds).
- Restated Audited Financial Statements under IndAS for 3-5 fiscal years.
- Management Discussion & Analysis (MD&A) and competitive strengths.
- Promoter Group details, Related Party Transactions (RPTs), and litigations.
- Note: DRHP deliberately excludes the issue price, dates, and number of shares.
What is RHP (Red Herring Prospectus)?
The Red Herring Prospectus (RHP) is the updated, legally binding document registered with the Registrar of Companies (RoC) and stock exchanges after addressing all SEBI observation letters and exchange queries.
- Contains the official Price Band (Floor Price and Cap Price).
- Specifies the exact Issue Opening Date and Issue Closing Date.
- Defines the minimum Bid Lot size for retail and non-institutional bidders.
- Includes confirmed Anchor Investor commitments finalized 1 day prior to public opening.
- Omits only the final strike price, which is determined post book building.
What is Book Building?
Book Building is an algorithmic price discovery mechanism wherein the issuer announces a Price Band (e.g., ₹240 to ₹250 per share) rather than a fixed price. Under SEBI regulations, the Cap Price cannot exceed 120% of the Floor Price.
- Investors submit bids specifying share quantities and prices within the band via ASBA.
- Retail investors have the option to bid at the dynamic "Cut-Off Price".
- After the bidding closes, lead managers construct the aggregate demand curve.
- The final Issue Price is fixed where total cumulative demand clears the available supply.

IPO Valuation
Investment bankers triangulate multiple valuation approaches to arrive at an optimal IPO price band:
EPS and PE Ratio
The Price-to-Earnings (P/E) ratio serves as the most widely referenced pricing benchmark in public markets:
Dilution
Dilution refers to the proportional decrease in existing shareholders' ownership percentage caused by the issuance of fresh equity shares:
Controlling Threshold: Promoters should carefully calibrate fresh issue sizing so that post-issue promoter shareholding remains comfortably above 51% (to pass special resolutions and retain operational control).
Market Capitalization
Market capitalization represents the total aggregate public market equity value of the company:
Pre-IPO Valuation
A Pre-IPO round is private equity capital raised 3 to 9 months prior to filing to establish a valuation baseline and de-risk the public offering:
