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 arrive in similar language and similar headlines, and they do quite different things.

Bonus issue

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

Take a company with 50 crore shares of ₹2 face value doing a one-for-one bonus. It 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 you as the holder, everything halves and doubles. Twice as many shares at half the price, the same proportion of the company, and the same value.

Economically, nothing is happening. 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.

It carries one signal. Capitalising reserves is permanent and reduces what can be distributed as dividend in future, so a board doing it is expressing some confidence that the reserves aren't needed. As signals go it's soft, and it's the only one.

In the accounts, face value stays the same and share capital rises. That's 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.

Split a ₹10 face value share into two ₹5 shares and the holder has 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.

Set the two side by side. A split reduces face value and leaves share capital unchanged, while a bonus keeps face value and increases share capital by transferring from reserves.

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

Companies do it because 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 aren't. 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. Holding 400 shares, you 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.

There are three outcomes, and only one of them is neutral.

Take up the rights and you end 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.

Sell the rights entitlement, which is separately tradeable on Indian exchanges, and you receive roughly the value of the discount, which compensates you for the dilution.

Do nothing and you're diluted and receive nothing. Your 400 shares fall from ₹1,200 to ₹1,120, and the ₹32,000 difference is a real loss.

The entitlement is tradeable so that the third outcome can be avoided. Letting it lapse is giving money away.

Then look at why the company is raising the money. The letter of offer states it under the objects of the issue. Money for a specific project earning a good return is one thing. Money to repay debt the operations couldn't 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.

On 50 crore shares, a company earning ₹615 crore 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. That's the wrong way round, and management is usually buying with the same optimism that drove the price up.

India has two routes, as of August 2026. One is a tender offer, where shareholders can participate proportionally and there's a reserved portion for small holders. The other is 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 doesn't. Treat the count of routes as a dated fact. The open-market route wasn't available for a stretch ending on 1 August 2026. 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. So check the routes currently permitted before you rely 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 you assume the announced price is what reaches a seller.

Set a buyback against a dividend and 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 don't. Where a buyback is done below intrinsic value, the non-selling holders gain, so 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's a yield of 1.5%, not 900%.

Convert every percentage dividend into rupees per share before you compare anything. It takes seconds and saves a lot of confusion. 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 if you buy on the Monday, the shares settle on the Tuesday and qualify for a Tuesday record date; buy on the Tuesday itself and they settle on the Wednesday and don't.

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 doesn't make a company more profitable, and a split doesn't make it cheaper in any sense that matters. Rights issues add capital, and whether that capital creates value depends entirely on what it's spent on. Buybacks return capital, and whether that creates value depends entirely on the price.

Announcing any of the four is no reason to buy or sell. It might be a reason to read the document that accompanies it. 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 doesn't. 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. In doing that, a board makes 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.

So a company with large free reserves and a long dividend record can do either, while 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 without much notice.

Catching it takes a simple check that's almost never run. Take the share count from five years ago and the count today, and compute the annual rate of increase. If the count grew 6% a year, the company 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 as well as 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.

Rights issues say the company needs capital and has chosen to ask its existing owners. That's the more shareholder-friendly route, because it gives every holder the chance to maintain their proportion. The objects of the issue say what it's for.

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

Buybacks say 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. First, does cash move, and in which direction? Second, ask whether your proportion of the company changes if you do nothing. Third, ask what the company gets out of it that it couldn't have got another way. A bonus and a split fail the first two tests, so they change nothing. Rights issues move cash in and change your proportion unless you act. So the entitlement is tradeable, and 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 wasn't. With three questions and four actions, 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 isn't 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 for choosing a buyback over a dividend, which is occasionally candid.

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