OFS vs buyback: what's the difference?
On OFS vs buyback: these two corporate actions are easy to confuse, but they move shares in opposite directions. An OFS, or offer for sale, is when promoters or large shareholders sell their existing shares to the market through the exchange. A buyback is when the company itself buys its own shares back from shareholders. In an OFS, shares flow out from big holders to the market; in a buyback, shares flow back to the company and are cancelled. Both are governed by SEBI frameworks.
Definition
OFS and buyback
are opposite corporate actions. An offer for sale (OFS) is promoters or large holders selling existing shares to the market through the exchange, with the money going to them. A buyback is a company repurchasing its own shares from holders, returning cash and cutting the share count. Source: SEBI.
OFS vs buyback: opposite directions of share flow
The cleanest way to hold the difference is to track who acts and where the shares and money go:
| Offer for sale (OFS) | Buyback | |
|---|---|---|
| Who acts | Promoters or large holders | The company |
| Share flow | Shares sold out to the market | Shares bought back and cancelled |
| Share count | Unchanged | Falls |
| Money goes to | The selling shareholders | Shareholders who tender |
| Typical effect | Promoter holding falls | Non-tendered stakes can rise |
Why the share count moves one way but not the other
A buyback extinguishes the shares it repurchases, so the total shares outstanding fall.

An OFS, by contrast, is only a transfer of existing shares from sellers to buyers, so the total count is unchanged. This is why the two actions can pull the shareholding pattern in different ways: an OFS typically lowers promoter holding, while a buyback shrinks the base and can lift the percentage held by those who did not tender.
Which disclosure do you read?
Both actions leave a dated public trail. An OFS is announced to the exchanges with the floor price, the date, and the quantity on offer, under the SEBI OFS framework introduced in 2012. A buyback is disclosed under the SEBI (Buyback of Securities) Regulations, 2018, with its route, size, price, and record date.
So on OFS vs buyback, the takeaway is direction: an OFS is holders selling out, a buyback is the company buying in. Flock reads the public disclosures behind both and keeps each one dated and sourced. What either means for your own decision is your call to make.
Frequently asked questions
What is the difference between an OFS and a buyback?
In an offer for sale, promoters or large holders sell existing shares to the market through the exchange, and the money goes to them. In a buyback, the company buys its own shares from shareholders and returns cash to them. The share flow runs in opposite directions. Source: SEBI.
Does an OFS or a buyback change the share count?
A buyback reduces the total shares outstanding, because the bought-back shares are extinguished. An OFS does not change the total count; it only transfers existing shares from sellers to buyers. Source: SEBI.
Who receives the money in an OFS versus a buyback?
In an OFS, the selling shareholders receive the money, not the company. In a buyback, the shareholders who tender their shares receive the money from the company. Source: SEBI.
How do OFS and buyback affect promoter holding?
An OFS is commonly used by promoters to reduce their stake, so promoter holding falls. A buyback can raise the percentage held by non-tendering shareholders, since the total count shrinks. Source: SEBI.
