Introduction
When a company decides to go public, there are several ways its shares can be offered to investors. One such method — often seen in large IPOs or follow-on public offers — is the Offer for Sale (OFS).
But what exactly is an OFS? How does it differ from a regular IPO issue? And what should retail investors keep in mind before subscribing?
In this blog, we’ll break down the concept of OFS in IPO, explain how it works, and help you understand why it plays a key role in India’s capital markets.

What Is OFS (Offer for Sale)?
Offer for Sale (OFS) is a mechanism that allows promoters or major shareholders of a listed company to sell their stake to the public through the stock exchange platform.
Unlike a traditional IPO, an OFS doesn’t issue new shares — instead, it provides a transparent route for existing shareholders (like promoters or institutional investors) to reduce their holdings and improve share liquidity.
Key Highlights
- Introduced by SEBI in 2012 to promote market transparency.
- Mainly used by listed companies with large promoter holdings.
- Offers are made via stock exchange bidding systems (NSE/BSE).
- Retail investors can also participate through their brokers.
How Does an OFS Work?
Here’s a step-by-step view of how the Offer for Sale process unfolds:
- Announcement:
The company informs the stock exchanges about its intention to conduct an OFS, including details such as total shares on offer and the floor price. - Bidding Period:
The offer usually remains open for one trading day. Investors place bids through their brokers, similar to an IPO application. - Allotment & Settlement:
Shares are allotted based on bid price and category, followed by T+1 settlement (usually next business day). - Listing Impact:
Since these are existing shares, there’s no new equity dilution. However, the increase in free-float may influence the stock’s short-term price movement.
OFS vs IPO: What’s the Difference?
| Feature | IPO | OFS |
|---|---|---|
| Nature of Shares | New shares issued | Existing shares sold |
| Objective | Raise fresh capital | Allow promoters/investors to exit |
| Duration | 3–5 days | 1 day |
| SEBI Regulation | SEBI (ICDR) Regulations | SEBI OFS Circular, 2012 |
| Participants | Retail, HNIs, QIBs | Retail, Mutual Funds, Institutions |

Why Do Companies Use the OFS Route?
- To meet SEBI’s minimum public shareholding norms.
- To allow early investors or promoters to book profits.
- To increase stock liquidity and free-float in the market.
- To provide a transparent and fair mechanism for stake sale.
Eligibility & Rules for OFS
According to SEBI guidelines:
- Only promoters and shareholders holding ≥10% of share capital can offer shares via OFS.
- At least 10% of the offer must be reserved for retail investors.
- Institutional investors can bid on a separate window before retail participation begins.
- A floor price (minimum selling price) must be disclosed before the opening of the offer.
Advantages of OFS for Retail Investors
- Transparent pricing: Orders and bids are visible on exchange systems.
- Shorter duration: The process completes in one day.
- Equal opportunity: Both institutions and retail investors can participate.
- Lower risk: Since shares already trade on exchanges, there’s no uncertainty about listing.
Risks and Limitations
While OFS brings convenience, investors should also consider:
- No new capital infusion — it doesn’t fund company growth directly.
- Price volatility — short-term dips can occur post-offer.
- Limited subscription window — just one trading day.
- Potential promoter signal — stake sale might reflect profit-booking or rebalancing motives.
How to Apply for an OFS
- Log into your trading account or broker platform.
- Select the ongoing OFS offer under the IPO/OFS tab.
- Enter bid quantity and price (not below floor price).
- Review and confirm the application.
- Funds are blocked until allotment via UPI/ASBA.
For new investors, this process is somewhat similar to IPO bidding. You can check out our complete explanation in IPO Allotment Process: What Retail Investors Need to Know to understand application flow and share allocation.
Real-World Example
Let’s say a listed company, XYZ Ltd., announces an OFS where promoters plan to sell 5% of their stake at a floor price of ₹450 per share.
If retail demand is strong and the stock trades at ₹480, the offer might get oversubscribed — indicating strong investor confidence.
Expert Insight
Market experts view OFS as a win-win mechanism — it helps promoters meet compliance norms while giving investors access to well-established listed companies at transparent prices.
However, analysts suggest evaluating:
- The reason for the stake sale,
- The company’s fundamentals, and
- Market conditions before applying.
FAQs on OFS (Offer for Sale)
1. What is an OFS in simple terms?
OFS allows promoters or large shareholders to sell part of their stake through the stock exchange so that retail investors can buy existing shares.
2. How is OFS different from an IPO?
An IPO issues new shares to raise fresh capital, while OFS involves selling existing shares. Hence, no new equity is created.
3. Can retail investors participate in an OFS?
Yes. SEBI mandates that at least 10% of the total offer is reserved for retail investors.
4. How can I apply for an OFS online?
You can apply via your broker’s IPO/OFS section using your demat and trading account.
5. Is an OFS good for short-term trading?
Sometimes. If demand is high and floor price is attractive, investors may gain — but always check fundamentals before applying.
6. Does OFS affect the company’s share price?
In the short term, yes — selling pressure can cause slight volatility. Over time, improved liquidity often stabilizes the price.
Conclusion
The Offer for Sale (OFS) route provides an efficient, transparent way for promoters to reduce holdings while giving investors a chance to own shares of well-established listed companies.
As an investor, always assess the company’s fundamentals, the purpose of the offer, and broader market sentiment before bidding.
