Quick Answer
An open offer in India is a public offer made by an acquirer to buy shares from the public shareholders of a listed company after crossing a threshold under the SEBI takeover code. It is triggered by acquiring 25% or more of the voting rights, or by gaining control, and the minimum offer size is 26% of the shares. Shareholders can tender their shares at the offer price, or choose not to.
An open offer in India is announced when a buyer takes a large stake or control of a listed company and must offer other shareholders a chance to sell. It protects minority investors, who would otherwise be left behind in a company with a new owner.
This guide explains when an open offer is triggered, how the price and size are set and what you can do as a shareholder when one is announced.

What Is an Open Offer in India?
An open offer is a public offer to buy shares from the existing shareholders of a listed company, made by an acquirer who has crossed certain limits under the SEBI takeover code. The aim is to give public shareholders an exit at a fair price when ownership or control changes.
What Triggers an Open Offer?
- Acquiring 25% or more of the voting rights in the company, alone or with others acting in concert.
- Acquiring control over the company, even with less than 25%.
- Acquiring more than 5% in a financial year, when the acquirer already holds between 25% and 75%.
- Indirect acquisitions, where control passes through a change in the parent company.
The 5% yearly limit for holders in the 25% to 75% band is called creeping acquisition. Beyond it, a new open offer is needed. A rule on maximum non-public shareholding, set at 75%, also affects how far an acquirer can go.
How Big Is an Open Offer and How Is the Price Set?
The minimum size of the offer is 26% of the target company's shares. The offer price must be at least the highest of several benchmarks, such as the highest price paid by the acquirer in a set period before the announcement, and the average market price over a defined period. This is meant to prevent public shareholders from receiving less than the acquirer paid.
| Item | Rule |
|---|---|
| Trigger | 25% voting rights or control |
| Minimum offer size | 26% of the company's shares |
| Offer price | At or above the highest of the benchmark prices |
| Creeping limit | Up to 5% a year for holders between 25% and 75% |
| Maximum non-public holding | 75% |
The Open Offer Process
- The acquirer makes a public announcement to the stock exchanges.
- A detailed public statement and the draft letter of offer are filed with SEBI.
- A letter of offer goes to shareholders with the terms and dates.
- A tendering window opens, during which shareholders can offer their shares.
- Payment is made to those whose shares are accepted.

The public announcement is the first formal step, and the date of the public announcement starts the timeline for the detailed statement and the offer. A late public announcement is itself a breach of the rules.
What Should Shareholders Do?
Compare the offer price with the current market price and with your view of the company's value. If the price is well above the market price, tendering may be attractive. If you believe the stock is worth more, you can stay invested. If the offer is for 26% and many shareholders tender, only a part of your shares may be accepted.
Keep in mind that open offers often cause price swings in the stock. Large companies in the Nifty 50 have fewer such offers, but mid-caps see them often.
If the acquirer is buying from the promoter, the offer price often reflects the price paid to the promoter, and public shareholders get the same chance at a fair price.
Open Offer vs Delisting Offer
An open offer follows a change in control, and the company usually stays listed. A delisting offer aims to remove the company from the exchange. The rules, prices and outcomes differ, so read the letter of offer to understand which one you are dealing with.
Check your demat account for tender instructions, since shares are usually tendered through your broker. Missing the tendering window means you cannot take part in the offer.

Conclusion
An open offer in India protects minority shareholders when control changes. It is triggered by crossing 25% of voting rights or gaining control, is for at least 26% of shares and carries a minimum price set by the SEBI takeover code.
Read the letter of offer, compare the price with your view of value and act within the tendering window if you wish to sell.
