Evaluate an Indian IPO by separating three different things: what the issuer officially discloses, what investors bid during the offer, and what unofficial grey-market quotes suggest. Subscription and GMP can describe demand or sentiment; neither establishes fair value or guarantees listing performance. For valuation, start with the current offer document and compare the company with relevant peers using consistent financial measures.
Start with the issuer’s current offer document
Read the issue’s Red Herring Prospectus (RHP) or prospectus before interpreting headlines or demand figures. It is the primary source for the offer terms and the issuer’s disclosures—not a regulator’s endorsement of the securities.

Work through the sections that bear on both the offer and the business:
- Issue terms: price band, offer size, and whether shares are being newly issued, sold by existing shareholders, or both.
- Business and risks: how the company earns revenue, its key dependencies, and the risks it identifies.
- Financial statements: examine revenue, profit, margins, debt, and cash generation across comparable periods.
- Use of proceeds: identify what the company says it will fund with fresh-issue proceeds. Proceeds from an offer-for-sale go to selling shareholders, not to the company.
- Shareholding and dilution: review ownership before and after the offer and how the share count may change.
SEBI’s investor guidance says, “Investors are advised to read the risk factors carefully before taking an investment decision in this offering.” The current offer document is where to verify the specific risks and terms for the IPO you are considering.

A prospectus is not a guarantee of accuracy or a regulator’s approval. For example, Sona Machinery Limited’s 2024 prospectus states that SEBI does not recommend or approve the securities and does not guarantee the prospectus’s accuracy or adequacy. That is an issuer-document example, not evidence about a different or current offer. Sona Machinery Limited prospectus hosted by SEBI.
Understand what the price band and book building tell you
In book building, investors bid within a stated price band. The issuer and book-running lead manager use bid demand in the price-discovery process; the final allotment price is not known in advance. The floor price is the minimum price at which bids may be made. SEBI’s book-building explainer and NSE’s IPO FAQs describe these mechanics.
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 book-built issue bid data, including category-wise details, for at least three days after bid closure. These are regulation-based requirements; check the live regulation text for any amendments before relying on them. SEBI ICDR regulation text.
The band tells you the permitted bidding range, not whether the company is worth the upper end. A high bid level or a final issue price within the band is not, on its own, a valuation assessment. Make that judgment from the company’s disclosures and relevant comparisons.
Read subscription data by category and by time
Subscription is a measure of bids received relative to shares available in a relevant category. A multiple such as “several times subscribed” describes demand for that offer at that point; it does not establish intrinsic value, an individual investor’s likelihood of allotment, or post-listing performance.
When checking figures, note both which category the number refers to and when it was observed. A live snapshot can differ from the final closing book as bids accumulate. Do not compare one IPO’s near-close figure with another IPO’s final figure as if they were equivalent. NSE explains that book-building demand is visible while bids accumulate, while the allotment price is not known in advance. NSE IPO overview.
- Open the IPO’s official page on the relevant exchange and locate its bid-details or subscription data. NSE and BSE publish public-issue bid information; interface labels and navigation may change.
- Record the observation time and whether the offer is still open or closed.
- Compare category-wise bids with the shares offered in those categories, rather than relying only on one headline total.
- For a comparison across IPOs, use figures captured at the same stage of each offer and retain the category breakdown.
A broker support guide points investors to the NSE bid-details pages and BSE public-issue bid-details pages. Use the exchanges themselves for current figures and verify the displayed observation time.

Treat GMP as unofficial sentiment, not a forecast
GMP, or grey-market premium, is an unofficial quotation outside the official exchange bid book. It is not an official subscription statistic or a stated value of the company. The official sources cited here do not establish GMP as a reliable forecast of listing returns.
If you encounter a GMP figure, ask who supplied it and when. It can change, and it should not be presented as a guaranteed listing gain, an official exchange figure, or a substitute for valuation analysis. SEBI’s investor guidance cautions against treating an issue price as indicative of the later market price. A 2024 Sona Machinery prospectus similarly says its issue price “should not be considered to be indicative of the market price” after listing, and that there is no assurance of sustained trading or of the price at which shares will trade. That wording is specific to the issuer’s document, but the risk is relevant when interpreting any offer price. SEBI investor guidance.

There is no universal valuation multiple that these sources establish as fair for every IPO. A useful assessment depends on the issuer’s sector, business model, financial period, and appropriate listed peers. Compare like with like: use consistent definitions and comparable reporting periods, and explain why each peer belongs in the comparison. A multiple without that context can obscure more than it reveals.
Alongside any valuation multiple, examine the factors that shape the company’s capacity to sustain or improve its financial performance:
- Revenue and profit growth over comparable periods.
- Margins and whether reported profits translate into cash generation.
- Debt and balance-sheet quality.
- Business-specific risks disclosed in the offer document.
- Offer valuation relative to relevant listed peers, including differences that make the comparison imperfect.
- Whether the offer is a fresh issue, an offer-for-sale, or a mix, and what the company says fresh proceeds will fund.
- Promoter and shareholder ownership changes and dilution.
Demand is a separate input, not a replacement for this work. A heavily subscribed category does not demonstrate that the offer is attractively priced; a GMP quote does not resolve whether the company’s valuation is supported by its financials.
Compare IPOs without confusing demand and value
If you are comparing two or more offers, keep the same analytical axes for each rather than choosing whichever headline number looks strongest.
| Comparison axis | What to check |
|---|---|
| Business and sector | How each company earns revenue and whether its business model makes the peer comparison meaningful. |
| Financial performance | Growth, margins, profits, and cash generation over comparable periods and with consistent definitions. |
| Balance sheet | Debt and other relevant indicators of financial strength or risk. |
| Offer valuation | Valuation against an appropriately selected listed-peer set, noting material differences. |
| Offer structure and proceeds | Fresh issue versus offer-for-sale and the stated purpose of any fresh proceeds. |
| Ownership and risks | Promoter or shareholder dilution and the risks disclosed in each current offer document. |
| Demand | Category-wise subscription at the same point in each offer, distinguishing live from final figures. |
These comparisons organize the evidence; they do not produce a certain outcome. Validate each company-specific fact against its current RHP or prospectus. No empirical statistic in the cited material establishes how accurately subscription multiples or GMP predict listing returns.
