A buyback is a company purchasing its own shares from shareholders and cancelling them. It is the reverse of a rights issue: instead of raising money by issuing shares, the company returns money by retiring them.
Total shares outstanding falls. Everyone who did not sell owns a slightly larger slice of the company.
Why companies do it
Surplus cash with no better use. If there is no attractive project to fund, returning cash to shareholders can be the sensible choice.
A signal. Buying back at a premium is management saying it considers the shares undervalued. That is a claim, not a fact, but it puts the company's money behind an opinion.
Improving per-share figures. Fewer shares means earnings per share rises mechanically, even with unchanged profit.
Supporting the price. A large buyer in the market supports the price during the buyback period.
Route 1 — Tender offer
The company offers to buy a fixed number of shares at a fixed price, usually at a premium to the market. A portion of the buyback is reserved for small shareholders, defined by the value of their holding on the record date.
How it works for you:
- You must hold the shares on the record date to be eligible.
- During the tender window, you offer some or all of your shares through your broker.
- Your shares are blocked.
- After the window, the company accepts shares up to the buyback size.
- Accepted shares are bought at the buyback price; unaccepted shares return to your demat account.
The acceptance ratio
If more shares are tendered than the company wants to buy, acceptance is proportionate within each category.
Buyback price ₹700. Market price ₹600. You tender 100 shares.
The small-shareholder category is tendered three times over, giving an acceptance ratio of about 33%.
33 shares are bought at ₹700 = ₹23,100. 67 shares come back to your demat account, still worth about ₹600 each.
Your gain is ₹100 × 33 = ₹3,300, not ₹100 × 100.
Note also that the market price often drifts up towards the buyback price once announced, which narrows the gap available to capture.
Route 2 — Open market buyback
The company simply buys its own shares on the exchange, over a period, up to a stated maximum amount and maximum price.
For you as a shareholder, there is nothing to do. There is no record date, no tender, no acceptance ratio. If you sell during that period you may be selling to the company without ever knowing it.
The company is not obliged to complete the full announced amount, and open market buybacks are sometimes completed only partially.
What to think about
Where is the money coming from? Surplus cash is one thing. A buyback funded by borrowing is a different proposition entirely.
Is the price sensible? A buyback well above a reasonable valuation destroys value for the shareholders who stay, the same way any overpriced purchase does.
Does it replace investment? A company with genuine growth opportunities generally has better uses for cash than buying its own shares.
Delisting is a different thing
Do not confuse a buyback with delisting, where a promoter seeks to buy out public shareholders entirely and remove the company from the exchange. Delisting follows its own SEBI process, including a reverse book building mechanism to discover the exit price. The outcome for a shareholder is very different: after a successful delisting, the shares no longer trade.
Key takeaways
- A buyback returns cash by purchasing and cancelling the company's own shares.
- A tender offer buys a fixed number at a fixed price, with a portion reserved for small shareholders.
- The acceptance ratio determines how many of your tendered shares are actually bought.
- In an open market buyback there is nothing for you to do.
- A buyback is not automatically good — check whether it is funded by surplus cash and priced sensibly.
