How to read a Red Herring Prospectus in 20 minutes

Nobody reads all 400 pages before bidding. You don’t need to. You need to know which seven places to look, and what to ask when you get there.

The Red Herring Prospectus is the company’s own legal document, and unlike a broker’s note or a grey-market number, it carries liability for what it says. The goal of twenty minutes isn’t a valuation. It’s deciding whether this offer deserves a proper look, or a pass.

This is the short version. For the full walkthrough with real numbers, read the DRHP and RHP guide, using Jio’s filings.

The route

1. The Offer: fresh issue or OFS?Find the split on the cover or in “The Offer”. Fresh issue money enters the company, OFS money leaves with the sellers. Ask: who is getting this cash?
2. Objects of the OfferLook for specifics with amounts. “Repay ₹X crore of debt” can be checked later, while a large “general corporate purposes” line can’t. Ask: could I hold them to this in a year?
3. Basis for Offer PriceThe company explains its price here, with peers. Check the peers are truly comparable in size and business. Ask: why were these peers chosen, and are any missing?
4. Restated Financial StatementsRead revenue, profit and operating cash flow across three years, side by side. Profit rising while operating cash flow falls deserves an explanation. Ask: is the profit turning into cash?
5. Risk FactorsSkip generic lines like “the economy may slow”. Hunt for what’s specific: one customer, one plant, one licence, a pending regulator. Ask: what could only hurt this company?
6. Capital StructureSee what promoters and early investors paid per share, and who is selling. Sellers who paid far below the offer price aren’t wrong to sell, but you should see the gap. Ask: what did they pay that I’m not paying?
7. Outstanding Litigation and Related Party TransactionsSize any cases against net worth. Check for sales, rent or loans involving promoter entities. Ask: does money flow to insiders outside the shareholding?

Three rules that help you read the structure

• Retail quota and limit. In a standard book-built profitable-company route, 35% of the offer is allocated to retail investors, a level SEBI kept after a 2025 proposal to reduce it for large IPOs was dropped. Applications above ₹2 lakh move out of the retail category.
• Oversubscribed retail books. Allotment is by lots, aiming for a minimum lot per successful applicant, so bidding for more usually doesn’t improve your odds much at very high subscription.
• Anchor lock-ins. Half of anchor shares are generally locked for 30 days and half for 90. Note the dates, because shares can come to market after them. Retail allottees generally have no lock-in.

These rules get amended, including changes reported in March 2026, so treat the offer’s own document and SEBI’s current ICDR Regulations as final.

Three common shortcuts to ignore

• The grey-market premium. It’s unofficial and unregulated, and it isn’t evidence of value.
• The subscription figure. It tells you other people want it. It doesn’t tell you the price is fair.
• The anchor list. Well-known anchors are worth noting, but they have different horizons and information from you.

When you’re done

Try to write down one sentence: “This company is selling X to fund Y, at a price justified by Z, and the main thing that could go wrong is W.”

If you can’t fill in those four blanks from the document, that’s a useful answer too. It’s a good reason to read more, or to skip this one.
