India's IPO Rules Revised: Tiered Minimum Public Offer Requirements

Government Revises Minimum Public Offer Rules for IPOs with Tiered Framework Based on Post-Issue Capital​

The Government of India has revised the minimum public offer requirements for companies planning to list on stock exchanges, introducing a tiered structure linked to the company’s capital after the public offering. The amendments were notified on March 13 through the Securities Contracts (Amendment) Rules, 2026, modifying Rule 19 of the Securities Contracts (Regulation) Rules, 1957.

The updated rules came into effect immediately upon publication in the Official Gazette and aim to align minimum public shareholding requirements with the size of the company’s post-issue capital calculated at the offer price.

Tiered Minimum Public Offer Structure Introduced​

Under the revised framework, companies will now be required to meet different minimum public offer thresholds depending on their capital after the IPO.

Companies with Capital up to ₹1,600 Crore​

Companies with post-offer capital of up to ₹1,600 crore must offer at least 25% of each class of equity shares or convertible debentures to the public.

Companies with Capital Between ₹1,600 Crore and ₹4,000 Crore​

Companies whose capital after the offering exceeds ₹1,600 crore but remains up to ₹4,000 crore must offer shares worth at least ₹400 crore to the public.

Companies with Capital Between ₹4,000 Crore and ₹50,000 Crore​

For companies with post-offer capital above ₹4,000 crore and up to ₹50,000 crore, the minimum public offer must be at least 10% of each class of equity shares or convertible debentures.

Such companies are required to increase public shareholding to at least 25% within three years of listing, as specified by the Securities and Exchange Board of India.

Companies with Capital Between ₹50,000 Crore and ₹1 Lakh Crore​

Companies in this bracket must offer shares worth at least ₹1,000 crore and not less than 8% of each class of equity shares or convertible debentures.

These companies must increase public shareholding to at least 25% within five years of listing.

Companies with Capital Between ₹1 Lakh Crore and ₹5 Lakh Crore​

Companies with capital after the offering above ₹1 lakh crore and up to ₹5 lakh crore must offer shares worth at least ₹6,250 crore and not less than 2.75% of each class of securities to the public.

Companies with Capital Above ₹5 Lakh Crore​

For companies whose post-offer capital exceeds ₹5 lakh crore, the minimum public offer requirement will be at least ₹15,000 crore and not less than 1% of each class of equity shares or convertible debentures.

Public Shareholding Increase Timelines for Large Companies​

The amended rules also define clear timelines for large companies to raise public shareholding after listing.

If a company lists with public shareholding below 15%, it must:

• Increase it to at least 15% within five years
• Increase it to 25% within ten years

If the public shareholding is already 15% or higher at the time of listing, the company must reach 25% within five years.

Additionally, the rules specify that at least 2.5% of each class of securities must be offered to the public, regardless of the provisions applicable to the largest companies.

Applicability to Existing Listed Companies​

The government clarified that the timelines to achieve prescribed public shareholding will also apply to companies that were listed before the amendment rules came into force.

Requirement for Superior Voting Rights Shares​

The notification also introduces provisions for companies that have issued equity shares with superior voting rights to promoters or founders.

Such companies, when seeking to list their ordinary equity shares, must simultaneously list the superior voting rights shares on the same recognised stock exchange.

Penalties for Non-Compliance​

Recognised stock exchanges have been given the authority to impose penalties on companies that fail to comply with public shareholding commitments made before the amendment rules came into force.

The revised framework is designed to create graduated listing requirements based on company size, while also ensuring that public shareholding norms are met within defined timelines after listing.
