Investor reviewing an IPO prospectus document

Every IPO news story mentions a DRHP or RHP at some point — "Company X files DRHP with SEBI" or "RHP reveals price band of ₹450–₹475." These two documents are the most important paperwork behind any IPO, yet most retail investors never open one before applying.

This guide explains what a DRHP and RHP actually are, how they differ from each other, what sections are worth your time, and where you can download them for free.

📌 Quick Answer: A DRHP (Draft Red Herring Prospectus) is the preliminary document a company files with SEBI before an IPO — it has business and financial details but no price band. An RHP (Red Herring Prospectus) is the updated version filed closer to the issue date, with the price band and dates added, but still without the final fixed price.

What is a DRHP (Draft Red Herring Prospectus)?

The DRHP is the first formal document a company files with SEBI when it plans to go public. It's a detailed disclosure of the business — covering the company's operations, industry, promoters, financial statements, risk factors, and how it intends to use the money it raises.

Crucially, a DRHP does not contain a price band or exact issue dates, because those details are decided much closer to the actual listing. Once filed, SEBI reviews the DRHP and may raise clarifications; the document is also published publicly so investors, analysts, and the media can review it before the IPO opens.

What is an RHP (Red Herring Prospectus)?

The RHP is the updated version of the DRHP, filed with SEBI and the Registrar of Companies a few days before the IPO actually opens for subscription. It carries all the same core information as the DRHP, but with the missing pieces filled in — the price band, the issue size, and the exact subscription dates.

The one thing an RHP still doesn't have is the final, fixed issue price — that's only confirmed after the book-building process closes and is published in the final Prospectus, filed after the issue is fully subscribed.

💡 Why "Red Herring"? The name comes from a bold red disclaimer traditionally printed on the cover page, stating the document is a draft and its contents are subject to change. That red-inked warning is where the "red herring" name originates.

DRHP vs RHP vs Final Prospectus — Quick Comparison

Document When It's Filed Price Band Included? Final Price Included?
DRHP Months before the IPO opens No No
RHP Few days before the IPO opens Yes No
Prospectus After the issue closes, before listing Yes Yes

Why Do Companies File a Draft First?

Filing a DRHP before the final RHP gives SEBI and the public an observation window. SEBI can raise clarifications or ask for additional disclosures, and the general public — including analysts and financial media — gets time to review the company's claims before it actually starts raising money. This structure exists to protect investors from companies rushing to market without adequate scrutiny.

What's Inside an RHP — Key Sections to Know

An RHP typically runs several hundred pages, but a handful of sections carry most of the useful information for a retail applicant:

How to Read an RHP — A Practical Approach

1

Start with Risk Factors

This section alone gives you an honest, SEBI-mandated list of everything that could hurt the business — read it before anything else.

2

Check the Objects of the Issue

An IPO that's mostly an Offer for Sale (existing shareholders exiting) tells a different story than one raising fresh capital for expansion.

3

Scan the Financial Summary

Look at revenue and profit trend over the last 3 years — consistent growth is a very different signal from a one-off spike right before the IPO.

4

Note the Price Band vs Peer Valuation

Once the RHP is out, compare the price band's implied P/E ratio against listed peers in the same sector.

Where to Find a Company's DRHP or RHP

DRHPs and RHPs are public filings. You can find them on SEBI's official website under the IPO filings section, on the NSE and BSE websites under their respective public issues pages, and on the issuing company's own website — usually under an "Investor Relations" or "IPO" section. Lead managers handling the issue also typically host a copy on their own site.

💡 Pramod's Rule: You don't need to read all 300+ pages. Ten minutes on Risk Factors, Objects of the Issue, and the Financial Summary tells you far more about an IPO's real quality than GMP or subscription numbers alone — treat those market signals as a supplement to the RHP, not a replacement for it.

Frequently Asked Questions

What is a DRHP in an IPO?
DRHP stands for Draft Red Herring Prospectus — the preliminary document a company files with SEBI before an IPO, containing business details and financials but not the price band or exact issue dates.
What is an RHP in an IPO?
RHP stands for Red Herring Prospectus — the updated, near-final version of the prospectus filed just before the IPO opens, including the price band, issue size, and subscription dates.
What is the difference between DRHP and RHP?
A DRHP is the draft filed with SEBI for public and regulatory review, without a price band. An RHP is the updated version filed closer to the issue opening, with the price band and issue dates added, but still without the final fixed price.
Why is it called a "red herring" prospectus?
The name comes from a mandatory red-coloured disclaimer printed on the cover page stating that the document is incomplete and subject to change, which historically gave the document its "red herring" name.
Where can I download an IPO's DRHP or RHP?
DRHPs and RHPs are publicly filed with SEBI and also published on the websites of the stock exchanges (NSE and BSE) and the issuing company itself, usually under an "Investor Relations" or "IPO" section.
Do I need to read the full RHP before applying for an IPO?
Reading the entire document isn't mandatory, but reviewing the risk factors, objects of the issue, and financial summary sections takes only a few minutes and gives you far more information than GMP or subscription numbers alone.
