SEBI Buyback Tender Offer Route: How It Works (2026)

The SEBI buyback tender offer route is the mechanism where a listed company offers to buy its own shares back at a fixed price from shareholders recorded on a record date, and those shareholders tender their shares into the offer. For roughly sixteen months it was the only route available, because SEBI had phased out open market buybacks with effect from 1 April 2025. That changed on 1 August 2026, when the open market route came back. If you are reading a buyback announcement in 2026, the first thing to establish is which of the two routes it uses.

How does the tender offer route work?

A tender offer buyback runs on a fixed price and a fixed record date. The company announces the buyback price and size, sets a record date, and every shareholder holding on that date gets a proportionate entitlement to participate. Shareholders who want to participate tender their shares through the exchange mechanism during the offer window; those who do nothing simply keep their shares.

Two features shape the outcome for retail holders. Entitlements are proportionate, so a shareholder tendering more than their entitlement is only assured of acceptance up to it, with the excess accepted only if others under-tender. And the regulations carry a reservation for small shareholders, which raises the proportion a small holder can expect to have accepted relative to a pure pro-rata split.

What changed on 1 August 2026?

The open market route, where the company buys its own shares on the exchange over a period rather than from a defined set of tendering shareholders, was wound down in stages by the 2023 amendment to the buyback regulations. The permitted size fell to under 15 percent of paid-up capital and free reserves to 31 March 2023, under 10 percent to 31 March 2024, under 5 percent to 31 March 2025, and then the route closed entirely from 1 April 2025.

SEBI has now reversed that. The SEBI (Buy-Back of Securities) (Amendment) Regulations, 2026 were notified on 1 July 2026 and took effect on 1 August 2026, restoring the open market route through stock exchanges in calibrated form.

Tender offer route vs open market route

The restored open market route also carries a pacing requirement: at least 40 percent of the funds earmarked for the buyback must be used in the first half of the buyback period, which is aimed at buybacks that are announced and then executed thinly.

Why the route matters when you read the disclosure

The route determines what the announcement actually commits the company to. A tender offer names a price and a size, and shareholders know their entitlement. An open market buyback names a maximum size and a maximum price, and how much is actually bought is revealed over the following weeks in the company's periodic disclosures to the exchanges.

That is a practical difference for anyone tracking corporate actions from filings. A tender offer has a record date to diarise. An open market buyback has a running disclosure to follow. Both start with a board meeting the company must notify to the exchanges in advance, which is the same prior-intimation machinery described in the corporate results calendar.

A buyback is also not the only way capital gets returned or a stake gets reduced. For the neighbouring mechanisms see what is a share buyback, delisting vs buyback and what is offer for sale.

Flock reports these corporate-action disclosures as the exchanges publish them, dated and linked to source. Which route a company chose, and what it then did, is a matter of record. What it means for a holding is your call.
