Offer for Sale (OFS): What It Means, How It Works & IPO vs OFS

What is an Offer for Sale (OFS)?
Offer for Sale, commonly known as OFS, is a mechanism that allows promoters of a listed company to sell their shares to the public through the stock exchange.
The OFS route was introduced by SEBI (Securities and Exchange Board of India) in 2012, mainly to make it easier for promoters to meet the minimum public shareholding norms (25% for listed companies) and to encourage transparent and efficient share sale practices.
Offer for Sale Meaning in Simple Terms:
In simple words, an OFS is like an auction where existing shareholders (usually promoters or large shareholders) sell part of their holdings to the public via the stock exchange.
How Does an OFS Work?
Unlike an IPO, where new shares are created and sold to raise fresh capital, an OFS involves the sale of existing shares only. Here’s how it works step by step:
Announcement: The company announces the OFS with details like the number of shares on sale, floor price, date, and bidding window.
Eligibility: Only the top 200 companies by market capitalization can use OFS.
Bidding: Investors bid for shares during market hours, usually for one trading day.
Allotment: Shares are allotted to bidders based on price and quantity bids, starting from the highest bid.
Settlement: Shares are transferred to successful bidders and money goes to the selling shareholders.
Who Can Participate in an OFS?
Retail Investors: 10% of the OFS issue size is reserved for retail investors.
Institutional Investors: Qualified Institutional Buyers (QIBs) and Non-Institutional Investors (NIIs) can also participate.
Existing Shareholders: Sometimes companies give preference to existing shareholders.
Retail investors can place bids through their broker, just like buying or selling regular shares.
When is an OFS Used?
The most common reasons companies use an OFS include:
Promoters diluting stake to comply with SEBI’s minimum public shareholding norms.
Government selling stakes in Public Sector Undertakings (PSUs).
Private companies letting early investors exit partially.
Key Features of Offer for Sale
No New Shares: Unlike an IPO, OFS doesn’t raise new capital for the company.
Limited to Top Companies: Only top 200 listed companies can use OFS.
Short Duration: OFS typically stays open for just one trading day.
Transparent Pricing: Floor price is declared upfront.
Direct Stock Exchange Route: Bids are placed through exchanges, ensuring transparency.

OFS vs IPO: Which is Better for Investors?
Whether IPO vs OFS is better depends on your investment goals.
