IPO Filing Process in India: Timeline, DRHP Approval & What Happens Next

Imagine a small but ambitious company in India that has grown steadily over the years. One day, its founders decide to go public. This journey—from being privately owned to becoming a publicly listed company—happens through an IPO (Initial Public Offering).

However, behind those 3–5 days of IPO bidding lies a 6–12 month-long regulatory journey. Understanding the IPO Filing Process in India is crucial for every investor who wants to make informed decisions.

What is an IPO?

An IPO (Initial Public Offering) is the process through which a private company offers its shares to the public for the first time and gets listed on stock exchanges like National Stock Exchange and Bombay Stock Exchange.

IPO Filing Process in India – Overview

The IPO filing process in India can be divided into three major stages:

1. Preparation Phase

2. DRHP Filing & SEBI Approval

3. IPO Launch & Listing

DRHP vs RHP vs Final Prospectus

Preparation Phase (3–6 Months)

Before filing an IPO, the company prepares internally by organizing financial, legal, and operational data.

Key Participants

• Merchant Banker – Manages IPO process

• Registrar – Handles allotment and refunds

• ROC (Registrar of Companies) – Legal authority

• Stock Exchanges – Listing platform

• Securities and Exchange Board of India – Market regulator

Documents Required for IPO Filing

Companies must prepare:

• Audited financial statements (last 3 years)

• Business model and risk factors

• Promoter details

• Legal compliance reports

• Capital structure

• Objectives of the issue

DRHP Filing Process (Core Step)

The most critical step in the IPO Filing Process in India is submitting the DRHP to SEBI.

The DRHP includes:

• Company overview

• Financial performance

• Risk factors

• Promoter background

It is made public for at least 21 days to ensure transparency.

SEBI Observation Letter

Once SEBI reviews the DRHP:

• It raises queries

• Requests clarifications

• Suggests changes

After satisfaction, SEBI issues an Observation Letter, which is valid for 12 months.

Mainboard IPO vs SME IPO

👉 SME IPOs generally carry higher risk due to lower liquidity.

What Happens After DRHP Approval?

Once approved:

• RHP is filed with ROC

• Price band is decided

• Roadshows are conducted

• IPO opens for subscription

IPO Allotment Timeline (T+3 Rule)

This faster cycle is introduced by SEBI to improve efficiency.

Latest SEBI Rules (Important Update)

• IPO listing timeline reduced to T+3 days

• Faster refund mechanisms

• Mandatory ASBA & UPI payments

These changes reduce investor risk and improve transparency.
