Buybacks, OFS and delisting: when the company comes to you

Sometimes it is the company or the promoter placing the order, not you. What each event means, when to participate, and what the acceptance ratio really decides.

Usually you decide when to buy and sell. Occasionally the other side initiates — a company offers to buy your shares back, a promoter offers to sell you theirs, or the company announces it wants to leave the exchange entirely. Each has different mechanics and a different correct response.

Think of it like this
The builder buying flats back

A builder announces he will buy back flats in his own society at ₹10 lakh above market. Some owners sell, some do not. Either way, fewer flats remain in circulation — and the ones left are a slightly larger share of the society.

In the market

That is a buyback. The company uses its own cash to purchase and cancel shares, so every remaining shareholder owns a marginally bigger slice of the same business.

The three events

EventWho is actingWhat it usually signals
BuybackThe company, using its own cashSurplus cash and a belief the shares are cheap
Offer for sale (OFS)The promoter or a large holder sellingAn owner reducing their stake, often at a discount to market
DelistingThe promoter buying out the publicThe promoter wants full ownership and no longer wants public scrutiny

The acceptance ratio decides everything

In a buyback you tender shares; the company accepts only a proportion. That proportion — the acceptance ratio — is what determines whether participating was worth the effort.

Worked example
A buyback at a 20% premium
500 shares, market ₹400, buyback ₹480
You tenderHoping all are bought at ₹480500 shares
Acceptance ratioHeavily oversubscribed, as most are18%
Actually acceptedGain of ₹80 × 90 = ₹7,20090 shares at ₹480
Remaining 410 sharesAnd the price often drifts back after the buyback closesReturned to you
Effective gainNot the 20% the headline suggested~3.6% on the position
The 20% premium applied to under a fifth of the holding. This is why buyback arbitrage is a small, fiddly return rather than the easy 20% it appears to be — and why the acceptance ratio matters more than the premium.

Delisting, and reverse book building

Delisting is different in kind. The promoter must buy enough shares to cross a threshold, and the price is discovered by reverse book building — public shareholders state the price at which they are willing to sell, and the promoter accepts or rejects the resulting discovered price.

Your two choices in a delisting
Tender your shares
  • Exit at the discovered price if the offer succeeds
  • Certain, clean and done
  • You give up any further upside
Hold on
  • If delisting succeeds, you hold an unlisted share
  • Selling later needs a private buyer at a negotiated price
  • A residual window exists but liquidity is poor

Buybacks reduce share count the same way a split increases it. Work through what happens to your holding and to earnings per share.

Whether a buyback is good news

Three questions
  1. 1
    Where is the cash coming from?

    Surplus cash on a strong balance sheet is healthy. A buyback funded by fresh borrowing is financial engineering, and it raises risk to flatter per-share numbers.

  2. 2
    Is the stock actually cheap?

    A buyback at a high valuation destroys value just as an overpriced acquisition does. Management buying its own shares expensively is still management overpaying.

  3. 3
    Is there anything better to do with the money?

    A company earning 25% on capital with room to expand should reinvest, not buy back. A buyback is the right answer when the reinvestment runway has closed.

Check yourself

A buyback is priced 25% above market but is oversubscribed with an acceptance ratio of 12%. Roughly what does a participant gain on their whole position?

Simple bhasha mein
Builder khud flat wapas khareed raha hai

Builder ne kaha — society ke flat market se 20% upar mein wapas le lunga. Sunke lagta hai 20% ka faayda. Par usne sirf 18% flat hi liye, baaki laut aaye. Toh aapka asli faayda 20% nahi, teen-chaar percent hai. Buyback mein premium nahi, acceptance ratio decide karta hai ki haath mein kya aayega.

What to remember
  • A buyback is the company buying; an OFS is the promoter selling. Opposite signals.
  • The acceptance ratio, not the premium, decides what you actually earn.
  • Retail shareholders get a reserved portion with better acceptance — a genuine structural edge.
  • Holding through a successful delisting leaves you with an illiquid unlisted share.
  • A buyback funded by debt, or done at a high valuation, is not good news.

Common questions

Short, direct answers to what people ask about this topic.

acceptance ratio meaning in buyback
The acceptance ratio is the proportion of the shares you tendered that the company actually buys back — tender 500 shares at a ratio of 18%, and only 90 are purchased at the buyback price while the rest are returned to you. It falls out of how heavily the offer is oversubscribed, so it is only known after the buyback closes. Because the premium applies only to the accepted portion, the acceptance ratio decides your real return far more than the headline buyback price does.
a promoter buying out public shareholders to remove a company from the exchange is called
Delisting. The promoter has to acquire enough of the public shareholding to cross the threshold SEBI sets, and the exit price is discovered by reverse book building, where public shareholders state the price at which they are willing to sell. If the discovered price is accepted the shares stop trading on NSE and BSE, and anyone who did not tender is left holding an unlisted share with no screen price.
what happens to buyback shares that are not accepted
They are credited back to your demat account after the buyback settles, and you can sell them on the exchange as normal. Only the accepted portion is bought at the buyback price; the balance stays with you at whatever the market price is by then, which is often lower than during the offer because the buyback demand has gone.
what is the small shareholder limit in a buyback
SEBI treats you as a small shareholder if the market value of your holding in that company is up to ₹2 lakh on the record date, and 15% of the buyback size is reserved for this category. Acceptance ratios inside the reserved portion are usually far better than in the general category, which is why the same buyback can accept most of a small holding and a sliver of a large one.
is buyback money taxable in india
Yes. For buybacks on or after 1 October 2024 the full amount you receive is taxed in your hands as a deemed dividend at your slab rate, with no deduction for what the shares cost you. The cost of those shares is instead treated as a capital loss, which can be set off against other capital gains under the normal rules. This replaced the older system where the company paid buyback tax and the receipt was exempt for the shareholder.
