Bonus issue, stock split, rights issue and buyback: what actually changes

You own 100 shares of a company trading at ₹240. It announces a one-for-one bonus issue. The next morning you own 200 shares at ₹120.

Your stake is worth exactly what it was worth. Nothing happened.

That sentence is true for a bonus and for a split, false for a rights issue, and complicated for a buyback. The four are announced in similar language, reported in similar headlines, and do quite different things. Here is what each one actually does.

Bonus issue

Free additional shares to existing holders, funded by converting reserves into share capital.

A company with 50 crore shares of ₹2 face value doing a one-for-one bonus issues another 50 crore shares, taking the count to 100 crore. Share capital rises from ₹100 crore to ₹200 crore, and reserves fall by ₹100 crore. Total equity is unchanged, because the money moved from one pocket of the balance sheet to another.

For the holder, everything halves and doubles. Twice as many shares at half the price, the same proportion of the company, and the same value.

What is actually happening. Nothing economic. The company's assets, profits and prospects are identical the day after. The only real effects are cosmetic: a lower price per share, which some investors find more approachable, and more liquidity.

The one signal it carries. Capitalising reserves is permanent and reduces what can be distributed as dividend in future. A board doing it is expressing some confidence that the reserves are not needed. That is a soft signal and it is the only one.

In the accounts. Face value stays the same and share capital rises. That is what distinguishes a bonus from a split, even though the effect on the holder looks identical.

Stock split

Dividing each share into several, reducing the face value proportionally.

A ₹10 face value share split into two ₹5 shares leaves the holder with twice as many shares worth half as much each. Share capital is unchanged, because the same total nominal value is now spread across more shares.

Split against bonus, in one line. A split reduces face value and leaves share capital unchanged. A bonus keeps face value and increases share capital by transferring from reserves.

For the holder. No difference between the two. Both produce more shares at a proportionally lower price and neither creates value.

Why companies do it. A high absolute share price is a barrier for small investors buying in whole shares, and a lower price improves the depth of the order book. Neither reason is about the business.

Both actions are frequently reported as though they were rewards. They are not. A company that "rewarded shareholders with a 1:1 bonus" gave them a piece of paper.

Rights issue

An offer of new shares to existing shareholders, in proportion to what they hold, usually at a discount to the market price. Unlike a bonus, it raises real money.

Take a one-for-four rights issue at ₹800 when the share trades at ₹1,200. A holder of 400 shares can buy 100 more at ₹800. The theoretical ex-rights price is the weighted average: four shares at ₹1,200 and one at ₹800 gives ₹1,120.

Three outcomes, and only one of them is neutral.

A holder who takes up the rights ends with 500 shares at ₹1,120, worth ₹5,60,000, having paid ₹80,000 for shares previously worth ₹4,80,000. No gain, no loss.

A holder who sells the rights entitlement, which is separately tradeable on Indian exchanges, receives roughly the value of the discount and is compensated for the dilution.

A holder who does nothing is diluted and receives nothing. Their 400 shares fall from ₹1,200 to ₹1,120, and the ₹32,000 difference is a real loss.

The entitlement is tradeable precisely so that the third outcome is avoidable. Letting it lapse is giving money away.

What to analyse. The reason for the raise, which is stated in the letter of offer under the objects of the issue. Money for a specific project earning a good return is one thing. Money to repay debt the operations could not service is another, and repeated rights issues at successively lower prices are a company funding losses from its shareholders.

Buyback

The company purchases its own shares and extinguishes them, returning cash to the holders who sell and raising the earnings attributable to those who stay.

A company earning ₹615 crore with 50 crore shares reports earnings of ₹12.30 a share. Reduce the count to 47.5 crore and earnings rise to ₹12.95, a 5.3% increase with no change whatever in the business.

Whether it creates value depends entirely on price. Buying shares below intrinsic value transfers value from the sellers to the holders who remain. Buying above it does the reverse. Most buybacks are announced after a strong run rather than after a fall, which is the wrong way round, and management is usually buying with the same optimism that drove the price up.

Two routes in India, as of August 2026. A tender offer, where shareholders can participate proportionally and there is a reserved portion for small holders, and an open-market purchase, where the company buys on the exchange over a period. The tender route lets a holder choose to sell; the open-market route does not. Treat the count of routes as a dated fact rather than a standing one. The open-market route was not available for a stretch ending on 1 August 2026, so a description of Indian buybacks written during that period would have named only the tender offer, and the next change will date this paragraph the same way. Check the routes currently permitted before relying on either.

Tax treatment has changed more than once, which affects the return an individual shareholder actually receives compared with the headline buyback price. Check the current position before assuming the announced price is what reaches a seller.

Buyback against dividend. Both return cash. A dividend goes to everyone in proportion; a buyback goes only to those who sell, and concentrates the ownership of those who do not. Where a buyback is done below intrinsic value, the non-selling holders gain, which is why it can be the better instrument.

Judge a buyback by the price paid, not by the size announced.

The one that catches Indian investors out

Dividends in India are frequently declared as a percentage of face value rather than of the share price.

A "900% dividend" on a ₹2 face value share is ₹18 a share. On a ₹1,200 share that is a yield of 1.5%, not 900%.

Convert every percentage dividend into rupees per share before comparing anything. The percentage is a fact about the face value, which is a nominal number set at incorporation and changed only by a split.

Dates, and the one that decides whether you qualify

Every one of these actions has a record date, on which the company checks its register to decide who is entitled.

The related trading concept is the ex-date. From that date the share trades without the entitlement, and the price adjusts by roughly the amount being distributed.

Under the current Indian settlement cycle, shares are delivered the day after the trade. So a purchase on the Monday settles on the Tuesday and qualifies for a Tuesday record date; a purchase on the Tuesday itself settles on the Wednesday and does not.

Count backwards from the record date in trading days, not calendar days.

A summary that fits in a table

The column that matters is the last one. Two of these four require no action from you. One of them punishes inaction. The fourth happens whether you participate or not.

What none of them change

The business.

A bonus does not make a company more profitable. A split does not make it cheaper in any sense that matters. A rights issue adds capital, and whether that capital creates value depends entirely on what it is spent on. A buyback returns capital, and whether that creates value depends entirely on the price.

The announcement of any of the four is not a reason to buy or sell. What it might be is a reason to read the document that accompanies it, because the letter of offer for a rights issue and the buyback offer document both say things about the company's plans and its view of its own value that appear nowhere else.

Why the accounting difference between a bonus and a split matters at all

To a shareholder it does not. To anyone reading the balance sheet it does, and the reason is worth one paragraph.

A bonus permanently converts reserves into share capital, and share capital is far more restricted in what it can be used for. Money that sat in free reserves and could have been paid as a dividend is now locked into the capital account. A board doing that is making a statement about how much of its accumulated profit it expects never to need to distribute, which is a mild signal of confidence and the only signal either action carries.

A split moves nothing. It renames the units.

Which is why a company with large free reserves and a long dividend record can do either, and a company whose reserves are thin can only split.

The dilution arithmetic nobody does

Rights issues, preferential allotments, qualified institutional placements and employee options all increase the share count, and their effects compound quietly.

The check that catches it is simple and almost never run. Take the share count from five years ago and the count today, and compute the annual rate of increase. A company whose count grew 6% a year has given away roughly a third of itself over that period, and every per-share figure it reports has been fighting that headwind.

Set that against the growth in profit. A company growing profit 12% a year while issuing 6% more shares a year is growing earnings per share at about 6%, and the difference went to whoever received the new shares.

Count the shares, not just the profit.

What each action says about management

A bonus or a split says very little, and reading either as a signal of confidence is reading more than is there.

A rights issue says the company needs capital and has chosen to ask its existing owners rather than the market at large, which is the more shareholder-friendly route because it gives every holder the chance to maintain their proportion. The objects of the issue say what it is for.

A preferential allotment or an institutional placement says the company needed capital and chose a route where existing small holders could not participate. That is legitimate and it is worth noticing, particularly where it repeats.

A buyback says management believes the shares are worth more than the price, or that it has no better use for the cash. Which of those it is can be judged from the price paid against the company's own history and from what else it was investing in that year.

The action is a decision. Decisions have a record, and the record is public.

The test that applies to all four

For any corporate action, ask three questions in order and the answer usually falls out. Does cash move, and in which direction? Does my proportion of the company change if I do nothing? And what does the company get out of it that it could not have got another way? A bonus and a split fail the first two tests, which is why they change nothing. A rights issue moves cash in and changes your proportion unless you act, which is why the entitlement is tradeable and why letting it lapse is giving money away. A buyback moves cash out and raises your proportion, which is good if the price paid was below what the shares are worth and bad if it was not. Three questions, four actions, and the arithmetic is short enough to do in your head.

Cash direction, proportion, and purpose.

Two of the four need no action from you.

One of them punishes doing nothing.

Where each one is announced, and what to read

All four are disclosed to the exchanges as material events, with the board resolution attached, and then again in the notice of the meeting that approves them.

For a rights issue the document to read is the letter of offer: it carries the ratio, the price, the record date, the objects of the issue and the promoter's stated intention about taking up their entitlement. A promoter who is not subscribing to their own rights issue has said something.

For a buyback the offer document gives the maximum price, the maximum number of shares, the route, and the proportion reserved for small shareholders in a tender offer. It also carries the board's reasoning about why a buyback rather than a dividend, which is occasionally candid.

For a bonus or a split the announcement is short because there is little to say, and the record date is the only operationally useful fact in it.

Read the resolution, not the headline.
