DRHP Meaning in IPO: What the Draft Red Herring Prospectus Tells Investors

Every mainboard IPO in India begins as a long PDF sitting on SEBI’s website. Get the DRHP meaning in IPO filings clear in your head and you can read that document before the price bands, grey market chatter and subscription numbers drown everything out. DRHP is short for Draft Red Herring Prospectus. It is the first full disclosure document a company files with the Securities and Exchange Board of India (SEBI) and the stock exchanges when it wants to go public. Below we cover what it is, how it differs from the red herring prospectus (RHP) and the final prospectus, the deadlines SEBI’s rules tie to it, and the sections we’d open first.

The rules we quote come from SEBI’s own FAQs on the ICDR Regulations (updated May 15, 2025) and the text of the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018, which most people just call the ICDR Regulations. For how IPOs work end to end, keep our pillar guide on IPO investing in India open alongside this one.

DRHP meaning in IPO, in one paragraph

SEBI’s FAQ defines a draft offer document as an offer document filed with SEBI (or with the stock exchanges, for SME issues) so that any changes can be specified before it goes to the Registrar of Companies (RoC). In a book-built mainboard IPO, that draft is the DRHP. It is made public on the websites of SEBI, the stock exchanges and the merchant banker, and anyone can comment on it within a set period.

“Draft” is the word to hold on to. A DRHP is not an offer to sell you shares. It is the first complete set of disclosures from the company and its lead managers, put out so that SEBI and the public can poke holes in it before anyone is asked for money.

“Red herring” is borrowed from securities practice overseas. As Investopedia explains, the name comes from a bold red notice on the cover of a preliminary prospectus warning that the information isn’t final and could change. India uses it the same way: a red herring document tells you nearly everything about the business, just not the final price or the number of shares.

DRHP, RHP and prospectus: three documents, three stages

You’ll usually run into three document names during a single IPO. SEBI’s FAQ tells them apart by stage:

• Draft Red Herring Prospectus (DRHP): filed with SEBI and the exchanges and opened up for public comments. SEBI can ask for changes before the company moves on.
• Red Herring Prospectus (RHP): used in a book-built public issue. According to SEBI’s FAQ it has all the relevant details except the price or the number of shares on offer, and it is filed with the RoC before the issue opens.
• Prospectus: has everything, price and number of shares included. In a book-built issue, the FAQ says this one is filed with the RoC after the issue closes, once the final price is known.

Put simply, you study the business in the DRHP, you check what changed and how the issue is structured in the RHP, and you learn the price from the price band announcement and the final prospectus.

The DRHP is the cheapest research you will ever get on an IPO: it arrives months before the price band, written under regulatory liability, and it is free on SEBI’s website.

The clocks that start once a DRHP is filed

Filing a DRHP sets off several timelines under the ICDR Regulations. Every point below is taken from the regulation text or the SEBI FAQ linked above.

1. A public comment window of at least 21 days

Under Regulation 26(1), the draft offer document filed with SEBI has to stay open for public comments for at least twenty-one days from the date of filing, hosted on the websites of SEBI, the exchanges where the shares will list, and the lead managers. The current text of Regulation 26(2), as reproduced on this bare-act copy of Regulation 26, also requires the issuer to publish a public announcement within two days of filing, inviting comments, in one English national daily, one Hindi national daily and one regional-language paper where its registered office sits. When the window closes, the lead managers file the comments, and any changes made because of them, with SEBI.

2. SEBI’s observations, then twelve months to launch

SEBI goes through the draft and issues its observations. Regulation 44(1) allows the public issue to open within twelve months from the date SEBI issues its observations. Miss that window and the company can’t just launch on the old clearance, which is why the same company sometimes turns up with a fresh DRHP a while later.

SEBI is careful about what its observations do and don’t mean. Its FAQ says that filing an offer document with SEBI should not be read as SEBI clearing or approving it, that SEBI does not recommend any issue, and that its observations do not make an investment safe. It is the lead manager who certifies that the disclosures are adequate and follow SEBI’s rules. The call on whether to invest is left to you, based on what the document discloses.

3. RHP filing, the price band and the opening date

When the company is ready to go, it files the RHP with the RoC. Regulation 44(2) says the issue can open only at least three working days after that filing. SEBI’s FAQ adds that an IPO issuer has to announce the floor price or price band at least two working days before the issue opens, in the same newspapers that ran the pre-issue advertisement. The gap between the floor and the cap of the band, the FAQ says, has to be between 5% and 20%.

4. Bidding, allotment, listing

SEBI’s FAQ says a book-built public issue stays open for 3 to 7 working days, and can be extended by 3 days if the price band is revised. Shares list within 3 days after the issue closes. Regulation 45(1) sets a minimum subscription of at least 90% of the offer through the offer document, except for an offer for sale. The bidding side is covered in our guide to the ASBA IPO application process.

Reading the issue structure from the draft

Well before anyone knows the price band, the DRHP shows how the offer is carved up. Here’s what we look for:

• Fresh issue vs offer for sale (OFS). Money from a fresh issue goes into the company. An OFS lets existing shareholders sell, so the cash goes to them instead. If a DRHP is mostly OFS, the IPO is largely an exit for the people already on the cap table.
• How the offer is split between investor categories. For a company on the standard route under Regulation 6(1), Regulation 32(1) keeps not less than 35% of the net offer for retail individual investors, not less than 15% for non-institutional investors and not more than 50% for qualified institutional buyers (QIBs), with 5% of the QIB slice reserved for mutual funds. Companies coming in under Regulation 6(2), which SEBI’s FAQ calls compulsory book-built issues, have to allot at least 75% to QIBs, with retail capped at 10% and non-institutional investors at 15%. The route a company takes tells you something about its profit history.
• Anchor investors. Regulation 32(3) allows the issuer to give up to 60% of the QIB portion to anchor investors. How that book works is in our explainer on the anchor investor in IPO rules.
• Promoter contribution and lock-in. Per SEBI’s FAQ, promoters of an unlisted issuer have to contribute not less than 20% of the post-issue capital, locked in for 1.5 years (three years if most of the fresh-issue money is going into capital expenditure). The rest of their pre-issue holding is locked in for 6 months from listing (one year in the capital-expenditure case). Other categories are covered in our guide to the IPO lock-in period.

Where we’d start reading a DRHP

Mainboard DRHPs regularly run to several hundred pages, and nobody needs to read them cover to cover. For a retail investor, this order works well.

Risk factors

Here the company and its lead managers list what they think could hurt the business. Skip the boilerplate that shows up in every document, broad economic risk and the like, and hunt for the company-specific items: customer concentration, reliance on one supplier or licence, approvals still pending, negative cash flows, or losses in recent periods. The risks placed near the top, and described with actual numbers, are usually the ones that count.

Objects of the issue

This tells you where the fresh-issue money is going: paying down debt, capital expenditure, working capital, acquisitions or general corporate purposes. Regulation 7(2) caps general corporate purposes at 25% of the amount being raised. If that line is big and vague, or most of the proceeds are going to repay loans linked to the promoters, slow down and look harder.

Capital structure and shareholding

This section shows who owns the company before the IPO, what recent investors paid for their shares, and any recent issues or transfers. Put those entry prices next to the price band when it comes out. A wide gap between what pre-IPO investors paid a year ago and what the public is being asked to pay isn’t wrong by itself, but it tells you how much of the re-rating others have already pocketed.

Restated financial information

DRHP financials are restated so the periods line up. Look at revenue, EBITDA, profit after tax, operating cash flow and borrowings across all the years shown, not just the latest one. Profits rising without operating cash flow following, or receivables suddenly swelling, are exactly the details a slick roadshow tends to skip.

Outstanding litigation and material developments

Legal cases involving the company, its promoters, directors and group companies are listed here, often with the amounts at stake. Tax demands, regulatory action and criminal cases against promoters deserve a note even when the company calls them immaterial.

Promoters, group companies and related-party transactions

See whether the business leans on related entities for sales, purchases, premises or the right to use a brand. When related-party dealings are heavy, the reported margins become harder to take at face value.

Read the DRHP for what the company has to admit, not for what it chooses to highlight. The risk factors, objects of the issue and litigation sections are where that admission lives.

Spotting the changes between DRHP and RHP

Between the draft and the RHP, the company deals with SEBI’s observations and the public comments, and usually updates its financials to a later period. When the IPO finally opens, put the two documents side by side:

• Did the issue size, or the split between fresh issue and OFS, change?
• Did any selling shareholders pull out or sell less?
• Are there new risk factors, fresh litigation, or different objects of the issue?
• Are the latest-period financials better or worse than in the draft?

A smaller OFS or a reworded objects section isn’t automatically bad news. But you only find out about it by comparing the documents. Once the issue goes live, the market signals take over, and our guides on what GMP in IPO means and mainboard vs SME IPO risk cover those.

Finding a company’s DRHP

According to SEBI’s FAQ, soft copies of offer documents go up on the websites of the issuer, the merchant banker, the stock exchanges and SEBI, under the public issues filings section on SEBI’s website. SEBI also updates the processing status of the offer documents filed with it every week. If something in a draft looks factually wrong, the FAQ says you can write to the lead manager named on the cover or complain to SEBI through its SCORES portal.

Where DRHP readers usually go wrong

• Taking a filing as a launch date. A DRHP signals intent, nothing more. The issue has to open within 12 months of SEBI’s observations, and some companies never get there.
• Treating the business overview as analysis. The company and its advisers write the industry and business sections. Use them to understand how the business makes money, then test the claims against the financial statements.
• Forgetting the OFS portion. The headline issue size includes money the company never sees.
• Assuming SEBI has signed off on the valuation. SEBI’s FAQ says plainly that it doesn’t recommend issues or approve what’s in an offer document. Pricing is down to the company and its lead managers, and then the market.

Pulling it together

So the DRHP meaning in IPO filings comes down to this: it is the draft disclosure that kicks off the regulatory process. At least 21 days of public comments, SEBI’s observations, a 12-month window to launch, then the RHP, a price band at least two working days before opening, bidding, and listing within three days of closing. For a retail investor it’s the best early look at a company’s risks, use of proceeds, ownership and track record, months before sentiment takes over.
