DRHP and RHP are two important documents in the IPO process, but they serve different purposes. A Draft Red Herring Prospectus (DRHP) is an early-stage offer document containing detailed information about the company, its business, financials, risks, promoters, shareholding and proposed use of IPO proceeds. The Red Herring Prospectus (RHP) is a later-stage document issued closer to the IPO and contains updated disclosures and issue details.
For pre-IPO investors, knowing the difference between DRHP and RHP matters because information can change between the two. The DRHP helps you understand the company and assess your existing or proposed unlisted-share position, while the RHP helps you check what has changed before the public issue.
You do not need to read every page of either document. A focused review of the offer structure, capital structure, financials, risks, related-party transactions, litigation and valuation can reveal many of the factors that matter most.
Pre-IPO investing often involves making decisions with less publicly available information than listed-equity investing. Investors may come across company presentations, broker commentary, transaction details or quoted prices for unlisted shares.
A DRHP provides a much more detailed disclosure base. It brings together information about the company's business, financial performance, ownership, risks, litigation, related parties and proposed IPO structure.
It can also help an existing pre-IPO shareholder understand what may happen to their position during the IPO.
For example, you can check:
However, a DRHP is still a draft. Issue size, disclosures and other terms can change before the RHP. Therefore, pre-IPO investors should treat the DRHP as an important due-diligence document, not the final version of the IPO terms.
| Document | When it appears | What it contains | What investors should focus on |
| DRHP | Earlier stage of the IPO process | Detailed company, financial, risk, ownership and proposed issue disclosures | Business quality, risks, capital structure, financials and proposed offer structure |
| RHP | Closer to the IPO opening | Updated disclosures and issue-related information, including the price band where applicable | Finalised issue terms, updated financials, valuation and changes from the DRHP |
| Prospectus | After the issue is priced | Final offer information and final issue details | Final terms and information after pricing |
The exact filing sequence can vary depending on the IPO process being followed. SEBI's public-issue records separately identify draft offer documents, red herring documents and final offer documents.
Some companies may also use the confidential pre-filing route and subsequently publish an updated draft offer document. Therefore, investors should check which version of the document they are reading and its filing date.
DRHP = What the company is proposing and how the business looks at the draft stage.
RHP = What has been updated as the IPO gets closer, including issue-related details available at that stage.
For a pre-IPO investor, the best approach is not to choose one and ignore the other. Read the DRHP for the detailed analysis, then compare the RHP with it to identify what changed.
You do not need to read a DRHP from page one to the last page. Start with the sections most relevant to the investment question you are trying to answer.
First, understand what the IPO is actually selling.
A fresh issue creates new shares and brings capital into the company. An offer for sale (OFS) involves existing shareholders selling their shares.
An OFS is not automatically a negative signal. Early investors, private-equity funds or other shareholders may reasonably want to realise part of their investment.
The important question is how the proceeds are split and why existing shareholders are selling.
If the company needs substantial capital for expansion but the IPO consists largely of OFS, that deserves closer examination.
For a pre-IPO investor, capital structure deserves particularly close attention.
Look at:
Most importantly, compare the prices at which earlier investors received shares with the price you paid or are being quoted.
A large difference does not automatically mean that your investment is overpriced. Earlier investors may have entered at a different stage of the company's development. But it is an important valuation question to investigate.
Also check the applicable lock-in provisions rather than assuming every pre-IPO shareholder has the same restriction. SEBI's current framework provides for lock-in requirements for specified pre-issue capital, subject to the applicable provisions and exemptions.
This section explains how the company proposes to use the fresh issue proceeds.
The money may be allocated towards:
Specific allocations are generally easier to evaluate than broad categories.
For example, if a company plans to use proceeds for a clearly identified manufacturing expansion, you can assess the proposed capacity addition and expected business impact.
If a significant portion is allocated to general corporate purposes, examine why and how that money fits into the company's broader plans.
Do not focus only on the latest year's revenue or profit.
Look at the restated financial statements over multiple years and examine:
One particularly useful comparison is profit versus operating cash flow.
If reported profits are growing but operating cash generation remains weak, investigate the reasons. Receivables, inventory and working-capital requirements can sometimes explain the difference.
Also read the accompanying notes and auditor-related disclosures rather than relying only on headline numbers.
Risk factors can look repetitive, but they should not be ignored.
Instead of reading them as a generic warning list, identify risks that are specific to the company.
Look for issues involving:
Do not assume that only the first few risk factors matter. Scan the complete section and identify the risks that could materially affect the company's operations, finances or valuation.
This section is particularly relevant when you are comparing a pre-IPO share price with the proposed IPO valuation.
Look at:
Then compare the implied IPO valuation with the price at which you acquired or are considering acquiring the unlisted shares.
If private-market transactions took place at substantially different valuations, understand what changed between those transactions and the IPO.
A business should not be evaluated only through financial numbers.
Review:
Frequent management or auditor changes may not automatically indicate a problem, but they can be worth investigating when combined with other governance concerns.
Related-party transactions deserve attention because they involve dealings between the company and entities or individuals connected to it.
Look for:
The key question is not simply whether related-party transactions exist. Many businesses legitimately have them.
Instead, consider their size, nature, frequency and importance to the company's operations.
Review litigation involving:
Do not judge litigation only by the number of cases.
Consider the amount involved, the nature of the dispute and whether a particular case could affect the company's licences, operations, assets or financial position.
Read the business section with one question in mind:
How does this company actually make money?
Understand:
After reading this section, you should be able to explain the company's business in two or three simple sentences.
If you cannot, go back and identify what you have missed.
The financial statements tell you what happened. Management discussion can help explain why it happened.
Compare management's explanation with the actual numbers.
For example:
Where comparable KPIs are disclosed, use them alongside financial statements to understand operating performance and compare the company with relevant peers.
Industry sections can help you understand:
However, do not treat industry projections as guarantees of company performance.
Compare industry growth expectations with the company's historical growth and actual ability to capture market share.
A practical approach is to read the document in stages.
Download the latest available DRHP from SEBI or the relevant lead manager's website.
Note the document name, filing date and version before starting.
SEBI maintains public-issue filing records where draft offer documents and later-stage offer documents can be accessed.
Start with the offer size.
Find out:
Build a simple table for yourself showing:
| Shareholder | Shares Held | Ownership | Acquisition/Issue Price Where Disclosed | Lock-in |
| Promoters | — | — | — | Check applicable provisions |
| Institutional investors | — | — | — | Check applicable provisions |
| Other pre-IPO investors | — | — | — | Check applicable provisions |
This makes ownership and dilution easier to understand.
Compare several years rather than focusing on one period.
Track revenue, margins, cash flow, debt and working capital.
Identify risks that could materially affect the business rather than simply counting the number of risk factors.
Review promoters, management, board composition, auditors and related-party transactions.
Compare the company's proposed valuation with relevant listed peers and disclosed recent transactions.
This is the step many pre-IPO investors overlook.
When the RHP becomes available, check:
The RHP should therefore be treated as an update and verification point, not merely another document to download.
| Factor | What to Check | Positive Signal | Red Flag |
| Offer structure | Fresh issue vs OFS | Clear purpose for both components | Large OFS without an understandable rationale |
| Use of proceeds | Allocation of fresh capital | Specific and measurable use | Large or unclear general-purpose allocation |
| Capital structure | Past allotments and ownership | Transparent ownership history | Unexplained low-priced allotments |
| Revenue quality | Customer and segment concentration | Diversified revenue | Heavy dependence on a few customers |
| Profitability | PAT, EBITDA and cash flow | Profits supported by cash generation | Profit growth without corresponding cash flow |
| Debt | Borrowings and finance costs | Manageable leverage | Rising debt or weak coverage |
| Governance | Promoters, board, auditors | Stable governance structure | Frequent unexplained changes |
| Related parties | Promoter-linked transactions | Transparent and understandable | Significant dependence on related entities |
| Litigation | Material cases and exposure | No material operational threat | Cases that could affect licences, assets or finances |
| Valuation | Peer multiples and offer pricing | Reasonable relative valuation | Large premium without clear justification |
Reading a DRHP does not automatically answer whether an investment is suitable.
Consider these questions:
A company can be growing quickly and still be expensive.
If the valuation already assumes very strong future performance, even a modest slowdown can affect the investment case.
Certain pre-issue shares are subject to applicable lock-in requirements after the IPO. The exact treatment depends on the shareholder category and current SEBI provisions, so check the relevant disclosures rather than assuming one universal period.
Understand whether the company is raising money primarily for expansion, debt reduction, working capital or other purposes.
The reason for raising capital matters.
Unlisted shares can be less liquid than listed shares. You may not always be able to exit when you want to.
An IPO filing does not guarantee that the issue will open on a particular date or that the company will eventually list.
Changing market conditions, regulatory requirements and company decisions can affect the timing of an IPO.
There may be limited buyers for unlisted shares before listing.
The price paid in the private market may differ substantially from the eventual IPO valuation.
Financial performance can change between the DRHP, RHP and eventual listing.
Related-party dealings, management changes or other governance concerns can affect the investment case.
The IPO process involves regulatory review and disclosure requirements. Filing a DRHP does not guarantee that the issue will proceed unchanged.
Listing does not guarantee a profit. The post-listing market price can fall below the price at which an investor acquired the unlisted shares.
Important details can be found deeper in the document.
Without understanding ownership and previous allotments, it is difficult to assess dilution and your relative entry price.
Industry growth does not automatically translate into company growth.
Margins, cash flow, debt and working capital provide a more complete picture.
The RHP can contain updated information and issue-related details.
A DRHP is part of the IPO process, not a promise of listing or investment returns.
The number of cases alone does not tell you their importance. Review their nature and potential financial or operational impact.
Supremus Angel focuses on pre-IPO and unlisted shares and provides company-level information and educational resources for investors researching this market.
For someone analysing a DRHP-stage company, such information can be used alongside the company's offer documents, financial disclosures and other independent research.
It should not replace reading the relevant offer documents or obtaining advice from a SEBI-registered investment professional where appropriate.
The DRHP should be treated as one important source of information within a broader due-diligence process.
The most useful way to think about DRHP vs RHP is not as a choice between two competing documents.
The DRHP helps you understand what the company is proposing and how the business looks at the draft stage. The RHP helps you check what has changed and what the IPO looks like closer to the issue.
For a pre-IPO investor, that distinction matters. Your analysis should connect the company's business, financial performance, ownership structure, risks and proposed valuation with the price you are paying for its unlisted shares.
A DRHP can be hundreds of pages long, but you do not need to read every page equally. Start with the offer structure, capital structure, financials, risks, litigation, related-party transactions and valuation. Then return to the RHP when it becomes available and compare the changes.
That approach turns a long regulatory document into a practical due-diligence exercise.
A Draft Red Herring Prospectus (DRHP) is an offer document containing detailed information about a company and its proposed public issue at an earlier stage of the IPO process. It does not contain the final price at which the shares will be offered.
A Red Herring Prospectus (RHP) is a later-stage offer document filed closer to the IPO. It contains updated disclosures and issue-related information, including the price band where applicable.
The DRHP is an earlier draft-stage disclosure document, while the RHP is a later-stage document containing updated information as the IPO moves closer to opening.
Both matter. The DRHP is useful for detailed due diligence, while the RHP helps you identify changes and review the updated IPO terms before the issue opens.
DRHPs are available through SEBI's public-issue filing section and may also be available on the websites of the company and its lead managers.
No. Filing a DRHP does not guarantee that the IPO will proceed, open on a particular date or result in a listing.
Yes. Companies can provide updated information and issue-related details as the IPO progresses. Investors should compare the later document with the earlier DRHP rather than relying only on the first filing.
Certain pre-issue shares are subject to applicable lock-in requirements under SEBI's ICDR framework, with the exact treatment depending on the shareholder category and applicable provisions. Always check the relevant offer document and current regulations.
Pay particular attention to weak operating cash flow, high customer concentration, significant related-party transactions, material litigation, unexplained share allotments, rising debt and valuations that appear difficult to justify against relevant peers.
No. A DRHP is an important due-diligence source, but investors should also consider valuation, financial performance, liquidity, market conditions, applicable lock-in requirements and their own circumstances. Where appropriate, investors should consult a SEBI-registered investment professional.
