Every year, dozens of companies transition from private entities to publicly traded corporations. This monumental shift — known as an Initial Public Offering (IPO) — involves a rigorous, multi-step process governed by regulatory authorities. For investors, entrepreneurs, and finance enthusiasts alike, understanding the IPO process is essential. This comprehensive guide walks you through every stage, from the very first document — the Draft Red Herring Prospectus (DRHP) — all the way to the final listing on a stock exchange.

What Is an IPO? Understanding the Basics

An Initial Public Offering (IPO) is the process through which a private company offers its shares to the general public for the first time. By doing so, the company transitions from being privately held to publicly traded. The primary goal is to raise capital — funds that can be used for business expansion, debt repayment, acquisitions, or working capital.

In India, IPOs are governed by the Securities and Exchange Board of India (SEBI) and regulated under the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018 (ICDR Regulations). Companies wishing to list on the NSE (National Stock Exchange) or BSE (Bombay Stock Exchange) must adhere strictly to these guidelines.

Types of IPO Offerings

• Fresh Issue: The company issues new shares to raise fresh capital for the business.
• Offer for Sale (OFS): Existing shareholders (promoters, PE investors, VCs) sell their shares to the public. No fresh capital flows into the company.
• Combination: A mix of fresh issue and offer for sale.

Step 1: Internal Decision and Board Approval

Before any external process begins, the company’s board of directors must formally approve the decision to go public. This involves a thorough internal assessment, including evaluation of the company’s financial health, growth projections, and capital requirements.

Key Activities at This Stage:

• Board resolution approving the IPO
• Appointment of merchant bankers (Book Running Lead Managers — BRLMs)
• Selection of legal advisors, auditors, and registrars
• Appointment of a due diligence advisor
• Decision on IPO size, price band, and structure

Step 2: Due Diligence and Document Preparation

Once the team is assembled, a comprehensive due diligence process begins. The BRLMs, legal advisors, and auditors examine every aspect of the business — financial statements, legal disputes, regulatory compliance, intellectual property, material contracts, and risk factors.

Documents Reviewed During Due Diligence:

• Audited financial statements (last 3 years minimum)
• Corporate governance documents
• Contracts with key customers, suppliers, and employees
• Litigation and legal proceedings
• Intellectual property ownership and patents
• Related party transactions
• Business licenses and regulatory approvals

Based on this extensive exercise, the Draft Red Herring Prospectus (DRHP) is prepared.

Step 3: Drafting the DRHP (Draft Red Herring Prospectus)

The Draft Red Herring Prospectus is the cornerstone document of any IPO. It is a detailed disclosure document that provides comprehensive information about the company to potential investors and regulatory authorities.

What Does the DRHP Contain?

• Business overview and history of the company
• Industry analysis and competitive landscape
• Management team profiles and track records
• Financial statements (3-5 years of audited data)
• Objects of the issue (how funds will be used)
• Risk factors (comprehensive list of business and sector risks)
• Legal and regulatory disclosures
• Promoter and shareholding pattern
• Related party transactions
• Dividend policy
• Litigation and legal proceedings
• Material developments post-balance sheet date

The term ‘Red Herring’ refers to the fact that the price band and number of shares to be offered are NOT mentioned in the DRHP — these are finalized later. The document is ‘red’ in spirit because it warns investors that information may be incomplete until SEBI’s approval.

Step 4: SEBI Filing and Review

Once the DRHP is prepared, the BRLM files it with SEBI (Securities and Exchange Board of India) along with the requisite fees. SEBI then begins its review process.

SEBI Review Timeline:

• SEBI typically takes 30 days from receipt to issue observations (the clock starts after all required documents are submitted).
• SEBI may seek clarifications or ask for additional information.
• Once SEBI is satisfied, it issues its ‘Observation Letter’ — this is NOT an approval but permission to proceed.
• The SEBI observation letter is valid for 12 months — the company must open its IPO within this period.

Simultaneously, the DRHP is made available for public viewing on the SEBI website and BRLM’s website for 21 days for public feedback.

Step 5: Stock Exchange Approval

Concurrently with or after the SEBI filing, the company applies for an ‘in-principle approval’ from the stock exchanges (NSE and/or BSE) where it intends to list.

Exchange Eligibility Criteria (BSE/NSE):

• Minimum net tangible assets of Rs. 3 crore in each of the preceding 3 full years
• Minimum average pre-tax operating profit of Rs. 15 crore in 3 out of the last 5 years
• Net worth of at least Rs. 1 crore in each of the preceding 3 full years
• Post-issue paid-up capital must be at least Rs. 10 crore
• For SME exchanges: different relaxed criteria apply

Companies not meeting the profitability criteria may still list under the QIB (Qualified Institutional Buyers) route, subject to conditions.

Step 6: Pre-IPO Placement (Optional)

Before formally opening the IPO to the public, companies may opt for a Pre-IPO placement — selling shares to select institutional investors, HNIs, or strategic investors at a price typically lower than the expected IPO price. This helps in price discovery and builds institutional interest.

Benefits of Pre-IPO Placement:

• Reduces the amount to be raised in the main IPO
• Creates anchor investor confidence
• Helps in refining the valuation
• Reduces risk for the company if the public issue underperforms

Step 7: Finalizing the Red Herring Prospectus (RHP)

After receiving SEBI’s observation letter, the company finalizes the Red Herring Prospectus (RHP) — which is different from the DRHP. The RHP includes the price band (or price) at which shares will be offered.

Key Additions in RHP vs DRHP:

• Price band (e.g., Rs. 120 to Rs. 130 per share)
• Offer size (total number of shares being offered)
• IPO open and close dates
• Allotment and refund timelines
• Basis of allotment details

The RHP is filed with the Registrar of Companies (RoC) and made publicly available.

Step 8: IPO Roadshow and Marketing

With all regulatory approvals in place, the company embarks on a crucial marketing phase — the IPO Roadshow. This is where the management team, led by the CEO and CFO, presents the company’s business model, growth story, and financials to institutional investors, fund managers, and analysts.

Roadshow Components:

• Domestic institutional roadshows (mutual funds, insurance companies, banks)
• International roadshows (FIIs — Foreign Institutional Investors)
• One-on-one meetings with large fund houses
• Analyst briefings and media interactions
• Investor presentations and Q&A sessions

The roadshow is critical for gauging investor appetite and setting the final price. BRLMs use feedback from roadshows to advise on price band finalization.

Step 9: Anchor Investor Allocation

One day before the IPO opens for public subscription, the company allocates shares to Anchor Investors. These are large institutional investors who commit to buying shares at or near the upper end of the price band.

Rules for Anchor Allocation:

• Minimum investment: Rs. 10 crore per anchor investor
• Lock-in period: 30 days from the date of allotment
• Maximum 60% of the QIB portion can be allocated to anchors
• At least 2 anchor investors required; no single anchor can get more than 25%

A strong anchor book — particularly from marquee names like SBI MF, Mirae Asset, HDFC AMC — signals strong institutional confidence and typically leads to strong listing.

Step 10: IPO Subscription – The Public Offer Period

The IPO subscription period is typically open for 3 working days. During this period, investors can apply for shares through ASBA (Application Supported by Blocked Amount) or UPI-based applications.

Investor Categories:

How to Apply for an IPO (Step by Step):

1. Log in to your demat/trading account or net banking portal
2. Navigate to the IPO section
3. Select the IPO you wish to apply for
4. Enter the number of lots and bid price (within the price band)
5. Enter your UPI ID (for UPI-based applications)
6. Accept the mandate on your UPI app
7. Your funds are blocked (not debited) in your bank account
8. Wait for allotment — funds are debited only if shares are allotted

Step 11: Basis of Allotment

After the subscription period closes, the registrar (e.g., KFin Technologies, Link Intime) processes all applications and determines the allotment.

Oversubscribed IPO — How Allotment Works:

• Retail (RII): If oversubscribed, a lottery system is used. Each valid application gets 1 lot or nothing — ensuring equal treatment.
• HNI/NII: Proportional allotment based on subscription level.
• QIB: Discretionary allotment by the company/BRLMs.

The basis of allotment is published on the registrar’s website and the BSE/NSE website.

Step 12: Refunds and Share Credit

Following allotment, the process moves quickly:

• Unblocked funds: Within 6 working days of IPO close, unblocked amounts are released to unsuccessful applicants.
• Share credit: Allotted shares are credited to the demat account of successful applicants.
• Refund: For ASBA applications, the blocked amount is simply unblocked; no actual transfer needed.

Step 13: Listing on Stock Exchange

The final and most anticipated step — the listing day! Shares begin trading on the stock exchange, and investors can buy or sell in the secondary market.

Listing Day Dynamics:

• Listing price is determined by pre-market session orders
• Strong IPOs often list at a significant premium to the issue price
• Weak demand may lead to listing at a discount
• GMP (Grey Market Premium) is an informal indicator of expected listing gains
• Lock-in periods apply to promoters and certain investors

Key Regulators and Participants in the IPO Process

SME IPO vs Mainboard IPO: Key Differences

IPO Valuation: How Is the Price Band Decided?

IPO pricing is one of the most critical and complex aspects of the entire process. The price band reflects the company’s intrinsic value, growth potential, and market sentiment.

Common Valuation Methods Used:

• Price-to-Earnings (P/E) Ratio: Comparing with listed peers in the same industry.
• EV/EBITDA Multiple: Enterprise Value to EBITDA, commonly used for capital-intensive sectors.
• Price-to-Book Value (P/BV): Common for banking and financial services companies.
• Discounted Cash Flow (DCF): Valuing future cash flows at a discount rate to arrive at present value.
• Revenue Multiple: Common for high-growth tech or startup IPOs without profits.

The final price band is determined by the BRLM in consultation with the company, factoring in investor feedback from roadshows, market conditions, and peer comparisons.

Grey Market Premium (GMP): What It Tells You

The Grey Market is an unofficial, unregulated market where IPO shares and applications are traded before the official listing. The Grey Market Premium (GMP) indicates the expected listing premium over the issue price.

Understanding GMP:

• High GMP (e.g., +Rs. 80 on a Rs. 500 issue price) = Strong listing expected
• Low or negative GMP = Weak demand; possible listing below issue price
• GMP is NOT a guarantee and can change rapidly based on market sentiment

While GMP is a popular tool among retail investors, SEBI does not regulate it, and it carries risk. Never make investment decisions solely based on GMP.

Post-Listing Obligations for the Company

Going public is not the end — it is actually the beginning of a new chapter with significantly enhanced responsibilities.

Continuous Disclosure Requirements:

• Quarterly financial results (within 45 days of quarter end)
• Annual report and AGM
• Corporate governance reports
• Material event disclosures (mergers, acquisitions, key personnel changes)
• SEBI LODR (Listing Obligations and Disclosure Requirements) compliance
• Related party transaction disclosures
• Shareholding pattern every quarter

Non-compliance with listing obligations can result in penalties, trading suspensions, and reputational damage.

Common Reasons Why IPOs Fail or Get Withdrawn

• Poor market conditions (e.g., market crash during IPO window)
• Overvaluation leading to weak investor interest
• SEBI queries and extended review periods
• Promoter/management controversies
• Sector-specific headwinds or regulatory changes
• Negative media coverage or investor sentiment
• Failed anchor investor book

Companies that withdraw IPOs can re-file after addressing concerns, but must repeat parts of the process including fresh SEBI filing.

Checklist for Investors Evaluating an IPO

• Read the DRHP/RHP thoroughly — especially the Risk Factors section
• Evaluate the Objects of the Issue — is capital being used for growth or promoter exit?
• Check the promoter background and track record
• Compare valuation with listed peers
• Assess the financial health: revenue growth, EBITDA margins, ROE, debt levels
• Look at anchor investor quality
• Understand the industry dynamics and competitive positioning
• Check for any pending litigations or regulatory actions
• Evaluate the lock-in period expiry — post-lock-in selling can pressure the stock
• Do not invest based solely on GMP, media hype, or subscription numbers

Frequently Asked Questions (FAQs) on IPO Process

Q1. How long does the entire IPO process take?

From internal decision to actual listing, the IPO process typically takes 12 to 18 months. The SEBI review alone takes 30–75 days, and post-SEBI activities can take 3–6 months.

Q2. Can retail investors apply in the QIB portion?

No. The QIB category is reserved for qualified institutional buyers such as mutual funds, FIIs, banks, and insurance companies. Retail investors apply in the RII or NII category.

Q3. What happens if an IPO is undersubscribed?

If an IPO fails to achieve minimum subscription (90% of the total issue size), SEBI mandates that all application amounts must be refunded and the IPO is considered failed. The company may re-launch with modifications.

Q4. What is the lock-in period for promoters?

Promoters’ shares that are part of the minimum promoter contribution (typically 20%) are locked in for 18 months from the date of allotment. Remaining promoter holdings are locked in for 6 months.

Q5. Is applying for an IPO through UPI safe?

Yes. UPI-based IPO applications are facilitated through SEBI-registered intermediaries and are completely safe. Funds are only debited upon allotment and are unblocked immediately if no allotment is made.

Conclusion

The IPO process is a complex, multi-stage journey that transforms a private company into a public one. From the meticulous preparation of the DRHP, through SEBI scrutiny, roadshows, and finally the excitement of listing day — each phase requires precision, compliance, and strategic execution.

For investors, understanding this process empowers better decision-making. For companies, it underscores the importance of choosing the right advisors, maintaining robust financials, and building strong narratives that resonate with the investing public.
