Scaling New Heights: A Comprehensive Guide to Main Board IPO Eligibility, Process, and Preparation for Indian Enterprises

Discover everything you need to know about launching a Main Board IPO in 2026. From SEBI eligibility and criteria to the step-by-step listing process and expert preparation tips, this guide empowers companies to raise capital and achieve global visibility.

For a growing company, the transition from a private entity to a publicly-listed giant is the ultimate “coming of age” ceremony. While an SME IPO offers a great starting point for smaller firms, the Main Board IPO is the big league reserved for companies with substantial scale, proven track records, and the ambition to attract global institutional investors.

Listing on the Main Board of the National Stock Exchange (NSE) or the Bombay Stock Exchange (BSE) provides unmatched liquidity, brand prestige, and access to a massive capital pool. However, the path is rigorous. This guide provides a 360-degree view of the Main Board IPO landscape, ensuring your leadership team is prepared for the journey.

1. Understanding the Main Board IPO Concept

A Main Board IPO (Initial Public Offering) is the process by which a large, established company offers its shares to the general public for the first time on the country’s premier trading platforms. Unlike the SME segment, which has relaxed norms for smaller businesses, the Main Board demands higher transparency, stricter financial disclosures, and a larger minimum issue size.

Why Go for the Main Board?

Access to Institutional Capital: Attracts FIIs (Foreign Institutional Investors), Mutual Funds, and Insurance Companies.
Enhanced Valuation: Publicly traded shares often command a “listing premium” due to transparency.
Currency for M&A: Use your listed shares as “currency” to acquire other companies.
Employee Retention: Attractive ESOPs (Employee Stock Option Plans) become liquid and valuable.

2. Eligibility and Financial Criteria (SEBI ICDR Regulations)

As of 2026, the Securities and Exchange Board of India (SEBI) maintains stringent “entry barriers” to ensure only quality companies reach the Main Board.

A. The Profitability Route (Entry Norm I)

To list under the standard route, a company must meet these “Three Pillars”:

Net Tangible Assets: At least ₹3 Crores in each of the preceding three full years (of which not more than 50% are held in monetary assets).
Operating Profit: Minimum average pre-tax operating profit of ₹15 Crores during the preceding three years.
Net Worth: At least ₹1 Crore in each of the preceding three full years.

B. The QIB Route (Entry Norm II)

If a company (often tech-heavy or high-growth startups) does not meet the profitability criteria above, it can still list provided that:

The issue is made through the Book Building Process.
At least 75% of the net offer is allotted to Qualified Institutional Buyers (QIBs).

C. Common Criteria for All

Post-Issue Paid-up Capital: Must be at least ₹10 Crores.
Minimum Issue Size: Generally ₹10 Crores or more.
Market Capitalization: Minimum ₹25 Crores at the time of listing.
Track Record: At least three years of operational history.

3. The Step-by-Step IPO Process

The journey from a “Board Resolution” to “Bells Ringing at the Exchange” typically takes 6 to 12 months.

Phase 1: Appointment of Intermediaries

A company cannot go public alone. You must appoint:

Merchant Bankers (BRLMs): To lead the entire process.
Legal Counsel: To handle due diligence and draft the offer document.
Registrars: To manage the allotment of shares.
Underwriters: To guarantee the subscription of the issue.

Phase 2: Due Diligence and DRHP Filing

This is the most critical phase. The Merchant Bankers and Legal teams conduct “Due Diligence” to verify every claim made by the company.

The DRHP: The Draft Red Herring Prospectus (DRHP) is filed with SEBI. It contains financials, risk factors, and the purpose of the fundraise.
SEBI Observations: SEBI reviews the DRHP and may request clarifications or changes.

Phase 3: The Roadshow and Marketing

Once SEBI gives the “Green Signal,” the leadership team goes on a “Roadshow.” They meet institutional investors across India (and sometimes globally) to build appetite for the stock.

Phase 4: Pricing and Bidding

Price Band: The company and the BRLMs set a price range (e.g., ₹500 – ₹525).
The Issue Period: The IPO stays open for 3-5 days for bidding.
Allotment: Shares are allotted based on the demand in Retail, HNI, and QIB categories.

Phase 5: Listing

Within a few working days of the issue closing, the shares are credited to the investors’ Demat accounts, and the company is formally listed on the NSE/BSE.

4. Preparation Needed: The Pre-IPO Checklist

Success in an IPO isn’t decided during the bidding week; it’s decided in the two years leading up to it.

1. Financial Housekeeping

Restated Financials: Ensure your accounts for the last 5 years are audited and restated as per Ind-AS (Indian Accounting Standards).
Internal Controls: Strengthen your Internal Financial Controls (IFC) to avoid any last-minute audit qualifications.

2. Corporate Governance

Board Composition: You must have a balanced board with the required number of Independent Directors and at least one Woman Director.
Committees: Establish Audit, Nomination & Remuneration, and Stakeholder Relationship committees.

3. Cleaning the Cap Table

Convert all outstanding CCPS (Compulsorily Convertible Preference Shares) or Loans into Equity.
Ensure all Promoters’ shares are in Demat form.

4. Defining the “Use of Proceeds”

SEBI is very strict about how you plan to use the money. Whether it is for Capex, Debt repayment, or General Corporate Purposes, every rupee must be justified.
