How to Read an IPO Prospectus (DRHP/RHP): Key Metrics Every Investor Should Check

When a new Initial Public Offering (IPO) hits the market, social media feeds, news channels, and market forums flood with hype, speculation, and unofficial grey market numbers. However, making sound investment decisions requires looking beyond the noise to the official source of truth: the Draft Red Herring Prospectus (DRHP).

Filed by the issuing company with market regulators like SEBI, the DRHP is a comprehensive document detailing a company's business model, financial history, management team, and potential risks. Learning how to analyze an IPO before investing begins with understanding this document, yet it is often a dense filing spanning 300 to 500 pages of financial jargon and legal terms.

To help you evaluate an IPO effectively, here is a step-by-step guide to reading a DRHP/RHP and identifying the key metrics that matter in just 15 to 20 minutes.

What are DRHP and RHP? Where Can You Find Them?

Before a company goes public, it prepares two key documents:

• Draft Red Herring Prospectus (DRHP): The initial draft submitted to regulatory bodies (like SEBI in India) and stock exchanges for review and public feedback. It contains complete business and financial details, but omits the exact issue dates and share price band.
• Red Herring Prospectus (RHP): The updated document filed just days before the issue opens, updated with regulatory feedback, official opening/closing dates, and the final price band.

You can download the DRHP or RHP from regulatory websites, stock exchange portals (NSE and BSE), or merchant banker platforms. Alternatively, modern tools designed to track IPOs aggregate these dense disclosures into organized, easy-to-read summaries right on your mobile screen.

The 6 Key Sections Every Investor Must Check

You don't need to read all 400 pages of the prospectus. Instead, focus on these six critical sections to evaluate the opportunity.

1. Objects of the Issue (Fresh Issue vs. OFS)

Check where the money raised from the IPO is actually going. Capital raised is typically divided into two categories:

• Fresh Issue: New shares issued by the company. The proceeds go directly onto the company’s balance sheet to fund expansion, reduce corporate debt, purchase equipment, or invest in R&D.
• Offer for Sale (OFS): Existing shareholders (promoters, early-stage private equity firms, or venture capitalists) sell their personal equity to the public. The proceeds go straight to these selling shareholders, not to the company.

Red Flag: If an IPO consists almost entirely of an Offer for Sale (OFS) with little to no Fresh Issue, existing insiders may be taking advantage of market sentiment to exit without leaving capital for company growth.

2. Financial Performance Trends (The 3-Year Test)

Jump straight to the Financial Information section and examine the financial statements across at least the last three fiscal years (FYs):

• Revenue Growth: Is top-line revenue growing year-over-year, or is it fluctuating wildly?
• EBITDA & Profit After Tax (PAT): Look at bottom-line earnings. Are profit margins expanding alongside revenue growth?
• Debt-to-Equity Ratio: Compare total borrowing against total equity. A high or rising debt burden can severely squeeze profits when interest rates rise.
• Operating Cash Flow (OCF): Check whether reported net profits translate into actual cash inflow from core business operations, rather than being stuck in unpaid receivables.

This step is especially critical when comparing risk profiles between large established firms and smaller enterprises; understanding Mainboard vs. SME IPOs require evaluating whether a smaller enterprise has the cash flow stability to sustain public listing costs.

3. Valuation Ratios & Peer Comparison

A great company can still be a poor investment if the issue price is overvalued. Look for the Basis for Issue Price section to review valuation metrics:

• Price-to-Earnings (P/E) Ratio: Calculated by dividing the offer price by the post-issue Earnings Per Share (EPS). Compare this multiple against established, publicly listed competitors in the same industry.
• Return on Net Worth (RoNW) / ROCE: Measures how effectively management generates profit from shareholder equity and total capital employed.
• Net Asset Value (NAV): The net value of the company per share before the offer.

Red Flag: An issue priced at a steep P/E multiple relative to well-established, highly profitable industry peers is often an indicator of aggressive pricing.

4. Risk Factors

Usually located near the beginning of the prospectus, the Risk Factors section is an honest look at what could go wrong. It is split into two categories:

• Internal Risks: Operational issues within the company’s control. Examples include customer concentration (e.g., getting over 50% of revenue from top 3 clients), pending lawsuits, expiring licenses, or pledged promoter shares.
• External Risks: Macroeconomic factors beyond the company's control, such as changes in government policy, foreign exchange volatility, or raw material price spikes.

5. Promoter Background & Shareholding Pattern

Evaluate the individuals running the company:

• Pre-issue vs. Post-issue Holding: How much equity will promoters retain after the listing? A significant promoter stake post-IPO aligns their long-term interests with retail shareholders.
• Track Record: Look for any history of regulatory non-compliance, defaults, or litigation involving the promoters or group companies.
• Category Reserved Shares: Check how shares are allocated across different investor buckets. Reviewing IPO subscription categories (QIB, NII, Retail) helps you understand institutional confidence and allocation odds for your application.

6. Lead Managers & Registrar Track Record

Pay attention to the Book Running Lead Managers (BRLMs) handling the issue. Reputable merchant bankers maintain strict due diligence standards, and reviewing their track record on previous IPO listings provides valuable insight into the quality of companies they bring to market. Furthermore, knowing the official registrar listed in the DRHP makes it easier when you eventually need to check IPO allotment status online on allotment day.

Quick Checklist: Common Red Flags to Spot Instantly

Before placing your bid, check for these warnings in the DRHP/RHP:

• Negative Operating Cash Flow: The company reports net profits on paper, but operational cash flow remains negative over consecutive years.
• Pre-IPO Financial Spikes: Revenue or net profit increases sharply in the final financial year immediately preceding the IPO filing.
• Major Pending Litigation: Unresolved lawsuits where potential damages exceed a significant portion of the company's net worth.
• High Customer Concentration: Overdependence on a single client, vendor, or supplier for the majority of revenue.
