To evaluate an Indian IPO, separate three things that are often blurred together: the issuer’s official disclosures, demand shown in exchange bid data, and unofficial market sentiment such as grey-market premium (GMP). Read subscription figures by category and timestamp, treat GMP as an unverified observation rather than a forecast, and judge the offer price against the issuer’s financials and relevant listed peers. None of these signals alone establishes fair value or predicts the listing price.
Start with the current RHP or prospectus
The red herring prospectus (RHP) or prospectus is the primary source for an issue’s terms and the issuer’s disclosures. Read it before relying on summaries or commentary. Focus on the sections that explain:
- Issue terms: the price band, issue size, offer structure, and dates.
- Business and risks: how the company earns revenue, what could disrupt it, and the risk factors investors are asked to consider.
- Financial statements: revenue, profits, margins, debt, and cash generation over the periods presented.
- Use of proceeds: how much is a fresh issue and how the company proposes to use those funds.
- Shareholding and dilution: the ownership impact of new shares and any shares offered for sale by existing holders.
A prospectus is an issuer disclosure document, not a regulator’s endorsement. For example, Sona Machinery’s March 2024 prospectus states that SEBI does not recommend or approve the securities and does not guarantee the document’s accuracy or adequacy. That prospectus is an example of disclosure language, not a current offer or a view on another IPO. SEBI’s investor guidance says: “Investors are advised to read the risk factors carefully before taking an investment decision in this offering.” Read SEBI’s investor guidance and verify all company-specific facts in the current offer document.
Understand the price band and book-building process
In a book-built IPO, investors bid within a stated price band. The issuer and book-running lead manager use the bids received to discover the issue price; 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 the process.

Under the SEBI ICDR regulation text accessed in 2026, the cap of the price band may not exceed 120% of the floor price. The same regulation text says exchanges display book-built issue bid data, including category-wise details, for at least three days after bid closure. These are regulatory provisions, not valuation rules; check the live regulation text for amendments before relying on them. See the SEBI ICDR regulations.
Read subscription data by category and time
Subscription data compares bids received with the shares available in the relevant category. A multiple is therefore a measure of demand for that category at a particular time—not a measure of the company’s intrinsic value. Bid demand accumulates during the offer, so a live snapshot can differ from the final closing book. Always record the observation time and whether the figure is provisional or final.
Use the official exchange issue page for current figures, and compare like with like: the same category and the same point in each offer. NSE explains that investors can observe demand as bids build while the allotment price remains unknown until price discovery. NSE’s IPO overview provides process context. A practical support guide points users to NSE and BSE bid-detail pages, but exchange interfaces and navigation can change; verify the current page and timestamp when checking an issue. See the exchange-data navigation guide.
- A high category multiple does not establish company quality, fair value, an individual investor’s allotment odds, or likely post-listing performance.
- Different categories reflect separate pools of shares and demand; do not treat one category’s multiple as the whole issue’s result.
- A live figure is a snapshot. Do not present it as the final subscription figure unless the offer has closed and the exchange data reflects the closing book.
Keep GMP separate from official subscription data
Grey-market premium (GMP) is an unofficial quotation or sentiment signal outside the official exchange bid book. It is not an exchange subscription statistic, and the official sources reviewed do not validate it as a reliable forecast of listing performance. GMP can change; a reported value is meaningful only with its source and observation time. Do not treat it as guaranteed listing gain, fair value, or a substitute for the offer document and financial analysis.

SEBI’s guidance cautions investors not to regard the issue price as indicative of the later market price. Sona Machinery’s 2024 prospectus makes the same point for that issuer: “The issue price … should not be considered to be indicative of the market price of the Equity Shares after the Equity Shares are listed.” It also says: “No assurance can be given regarding an active or sustained trading in the Equity Shares nor regarding the price at which the Equity Shares will be traded after listing.” These are risk disclosures, not predictions about a particular IPO.

Assess valuation using issuer data and relevant peers
There is no universal valuation multiple that these sources establish as “fair.” Start with the valuation implied by the offer price, then compare it with listed companies that have genuinely comparable businesses. Use consistent financial definitions and comparable periods; a ratio based on one company’s recent year and another company’s different reporting period can mislead.
Interpret a peer comparison alongside the issuer’s operating and balance-sheet picture:
- Growth and profitability: consider revenue and profit trends, margins, and whether growth is accompanied by durable earnings.
- Cash generation and debt: compare cash generation with reported profits and examine debt and balance-sheet quality.
- Business risks: account for the risks described in the offer document rather than assuming peers face identical conditions.
- Offer structure and proceeds: distinguish a fresh issue, which raises money for the company, from an offer for sale by existing shareholders; assess the stated use of fresh-issue proceeds.
- Ownership and dilution: consider how the offer changes shareholding and what dilution means for existing and new shareholders.
Explain why each peer belongs in the comparison and where it differs. Sector, scale, business mix, growth, margins, and financial reporting can make apparently similar companies poor matches. Without the actual offer document, relevant financial period, sector, and defensible peer set, an issue-specific valuation conclusion cannot be reached responsibly.
Compare IPOs on consistent terms
When comparing two or more Indian IPOs, use the same analytical axes for each and verify company-specific details in each current RHP or prospectus:
- Business and sector.
- Revenue and profit growth, margins, and cash generation across comparable periods.
- Debt and balance-sheet quality.
- Offer valuation relative to an appropriately selected listed-peer set.
- Fresh issue versus offer for sale, plus the intended use of proceeds.
- Promoter and shareholder dilution, and the disclosed risk factors.
- Category-wise demand observed at the same point in each offer.
This is a framework for organizing evidence, not a formula that produces a certain outcome. Subscription multiples, GMP, and valuation comparisons do not assure a gain or a particular post-listing price.
