Tender offer vs open offer: US and India
On tender offer vs open offer, both are ways to buy shares from a company's holders during a change of ownership, but they come from two different rulebooks. A tender offer is the US mechanism, a public bid at a set price governed by SEC rules. An open offer is the Indian mechanism, triggered when an acquirer crosses a threshold under the SEBI takeover code. This guide compares tender offer vs open offer across the trigger, the rules, and the filings. It is not investment advice.

A tender offer versus an open offer
are both offers to buy shares from a company's holders. A US tender offer is a public bid at a set price under SEC rules. An Indian open offer is a mandatory offer triggered when an acquirer crosses the SEBI takeover-code thresholds. The trigger and pricing rules differ. Source: SEC, SEBI.
How do a tender offer and an open offer differ?
The clearest split is voluntary versus mandatory, and the disclosure that follows.
| What to check | US tender offer | India open offer |
|---|---|---|
| Rulebook | SEC tender-offer rules | SEBI SAST Regulations, 2011 |
| Usually | Voluntary bid | Mandatory once thresholds are crossed |
| Trigger | Bidder's choice | 25% of voting rights, or change of control |
| Size | Set by the bidder | At least 26% more from public holders |
| Key filings | Schedule TO, Schedule 14D-9 | Public announcement, detailed public statement, letter of offer |
25% then 26%
India: crossing 25% of voting rights triggers an open offer for at least 26% more of the shares

Which applies to the company you follow?
It depends on the market. For a US-listed company, control bids come as a tender offer. For an Indian listed company, a large acquisition triggers an open offer under the takeover code, explained in open offer under SEBI SAST. The people counted toward the Indian threshold include persons acting in concert.
Where this matters for a smart-money reader
Both offers are public and dated, so a change of control leaves a clear paper trail in either market. The trigger levels and timelines differ, which is why reading the right filing for the right market matters.

Frequently asked questions
What is the difference between a tender offer and an open offer?
A US tender offer is a public bid to buy shares from holders at a set price, governed by SEC rules. An Indian open offer is triggered when an acquirer crosses a threshold under the SEBI takeover code and must then offer to buy from public shareholders. Source: SEC, SEBI SAST 2011.
When is an open offer triggered in India?
Under the SEBI takeover code, acquiring 25% or more of the voting rights, or taking control, triggers a mandatory open offer. The acquirer must then offer to buy at least 26% more of the shares from public shareholders. Source: SEBI SAST Regulations, 2011.
Is a US tender offer always mandatory?
No. A US tender offer is usually a voluntary bid a party chooses to make for control or a large stake. India's open offer, by contrast, is mandatory once the takeover-code thresholds are crossed. Source: SEC, SEBI.
What filings does each create?
A US tender offer produces a Schedule TO from the bidder and a Schedule 14D-9 from the target. An Indian open offer produces a public announcement, a detailed public statement, and a letter of offer under the SAST regulations. Source: SEC, SEBI.
