To evaluate an Indian IPO, separate four different things: the issuer’s official disclosures, exchange-reported bids, unofficial grey-market sentiment, and your own valuation analysis. Subscription figures and GMP can describe demand or sentiment, but neither establishes a company’s fair value or guarantees its listing price. Start with the current offer document, verify bid data on an exchange, then assess the offer price against the issuer’s financials and relevant listed peers.
1. Start with the current RHP or prospectus
The Red Herring Prospectus (RHP) or prospectus is the primary source for an IPO’s terms and the issuer’s disclosures. Read it before interpreting demand figures or comparing the offer price with peers. It is an issuer disclosure document, not a regulator’s endorsement: SEBI says it does not recommend or approve securities or guarantee a prospectus’s accuracy or adequacy. For example, that qualification appears in Sona Machinery Limited’s prospectus filed in 2024, which is an example rather than a current offer document (SEBI-hosted Sona Machinery prospectus).
Focus your first read on the sections that can change the investment case:
- Issue terms: price band, issue size, lot size, dates and the split between fresh issue and offer for sale (OFS).
- Business and risks: how the company earns revenue, its dependencies and the risk factors it discloses.
- Financial statements: revenue, profitability, cash generation and debt across comparable periods.
- Use of proceeds: how much money goes to the company and what it plans to fund, versus proceeds going to selling shareholders in an OFS.
- Shareholding and dilution: the ownership changes expected after the offer and any relevant promoter or shareholder disclosures.
SEBI’s investor guidance says, “Investors are advised to read the risk factors carefully before taking an investment decision in this offering.” (SEBI investor guidance.)

2. Understand the price band and book-building process
In a book-built IPO, investors bid within a price band. The issuer and book-running lead manager use demand received through bids as part of price discovery; the final issue price is determined after bids are received. SEBI’s explainer describes this process, and its regulation text sets out related requirements (SEBI book-building process explainer; SEBI ICDR regulations).
The floor price is the minimum at which bids may be made. NSE notes that in book building, investors can observe demand as the book accumulates, but the allotment price is not known in advance (NSE IPO FAQs). The band gives you the permitted bidding range; it does not, by itself, tell you whether the company is attractively valued.
Under the SEBI ICDR regulation text accessed in 2026, the cap of a price band may not exceed 120% of its floor price. The same text says exchanges display category-wise bid data for a book-built issue for at least three days after bid closure. Regulations can be amended, so verify the live text and the specific offer documents when applying these provisions to an IPO.
3. Read subscription data by category and time
Subscription data compares bids received with the shares available in a relevant portion of the offer. A multiple such as “10 times subscribed” is incomplete unless you know which category it refers to and when the figure was observed. Exchange pages report category-wise bids, and the number can change during the offer period. Distinguish a live snapshot from the final closing book; they are not interchangeable (NSE market data; BSE public issues).
For each figure, record the source, category and observation time. Use the relevant official exchange page for current bids; a practical guide also points readers to NSE and BSE bid-detail pages, but exchange interfaces can change (Zerodha guide to checking IPO subscription status).
- Category: compare a category’s bids with shares reserved for that category, rather than treating one category’s multiple as the whole issue’s demand.
- Timing: label an intraday or mid-offer observation as a snapshot. Use the final number only after the offer closes.
- Meaning: a high multiple indicates bids relative to shares available in that category at that time. It does not establish company quality, intrinsic value, an individual investor’s likelihood of allotment, or post-listing performance.
Demand becomes visible as bids accumulate, but it is still a measure of participation in that offer—not a substitute for reading the issuer’s disclosures.
4. Treat GMP as unofficial sentiment, not an official statistic
GMP, or grey-market premium, is an unofficial quotation associated with trading outside the official exchange bid book. It is not an exchange-reported subscription figure. The official materials cited here do not establish GMP as a reliable forecast of listing returns, and they provide no predictive accuracy statistic for it.
If you encounter a GMP figure, check who supplied it and when it was observed. Treat it as a changeable sentiment signal, not a guaranteed listing gain, fair value or substitute for the offer document. SEBI’s investor guidance warns against treating the issue price as indicative of the later market price; an issuer prospectus makes the same point about the eventual market price and notes that neither active or sustained trading nor a particular post-listing price is assured (SEBI investor guidance; Sona Machinery prospectus, filed in 2024).
5. Judge valuation using issuer data and relevant peers
Valuation is company-specific. Compare the offer valuation with relevant listed peers, using consistent financial definitions and comparable reporting periods. Explain why those businesses are suitable comparisons and where differences in scale, business mix or risk make the comparison imperfect. No single valuation multiple is established as universally “fair.” Without a specific issuer, offer document, financial period, sector and peer set, a responsible issue-specific valuation conclusion is not possible.
Build the assessment from the offer document rather than from a subscription multiple or GMP quotation:
- Growth and profitability: examine revenue and profit trends over comparable periods, and whether margins appear sustainable in light of the disclosed business and risks.
- Cash generation and debt: compare reported profits with cash generation and consider balance-sheet quality and debt obligations.
- Offer price versus peers: select relevant listed companies, use matching periods and definitions, and state the limitations of the peer set.
- Issue structure: distinguish fresh capital raised for the company from an OFS, and assess the disclosed purpose of proceeds.
- Dilution and risks: consider ownership changes and the issuer’s disclosed risks alongside any valuation comparison.
These are analytical prompts, not a formula that predicts an outcome. The offer price and the level of demand do not assure the price after listing.
6. Compare IPOs on consistent terms
When comparing two or more offers, align the evidence before drawing conclusions. Comparing one offer’s final subscription with another’s early snapshot, or using different financial periods for peer multiples, can make a comparison misleading.

| Comparison axis | Keep consistent |
|---|---|
| Business and sector | Compare the nature of the businesses and explain material differences. |
| Growth, profitability and cash generation | Use comparable reporting periods and definitions. |
| Debt and balance sheet | Assess each issuer’s disclosed debt and balance-sheet quality. |
| Offer valuation | Use an appropriately selected listed-peer set and disclose its limits. |
| Fresh issue and OFS | Separate capital going to the company from shares sold by existing holders; examine stated use of proceeds. |
| Dilution and risks | Check each offer document’s ownership disclosures and risk factors. |
| Category-wise demand | Compare the same category at the same point in each offer, preferably using official exchange data. |
Verify each company-specific fact in that issuer’s current RHP or prospectus. A comparable framework makes differences easier to see; it does not turn demand or valuation ratios into a certain prediction.
Quick Recap
7. A practical evaluation sequence
- Open the current RHP or prospectus. Confirm the offer terms, business, risks, financial periods, proceeds and shareholding disclosures.
- Write down the price band and offer structure. Separate the fresh issue from any OFS and note what the company says it will do with proceeds.
- Check official exchange bid data. Record category and observation time; update the figure as the offer progresses and label the final book only after closure.
- Put any GMP observation in a separate note. Attribute it to its supplier and time, and do not combine it with official subscription data or treat it as a forecast.
- Compare valuation with relevant peers. Use comparable periods and definitions, then assess growth, margins, cash generation, debt, dilution and risks.
- Make the decision on the disclosed business and price. Demand indicators may add context, but they do not replace your assessment of the offer or guarantee post-listing performance.
