What it means
In a reverse split, shareholders swap a set number of old shares for one new share. In a 1-for-10 reverse split, for example, every 10 old shares become 1 new share, and the share price rises roughly tenfold.
The shareholder owns fewer shares, but each one is worth more, so the total value of the holding stays the same. Companies usually do this when the share price has fallen very low.
Exchanges set minimum listing prices, and a stock trading well below that level can be delisted (removed from the exchange). A reverse split lifts the price back above the minimum without changing the underlying business.
There are other reasons too. A very low share price can put off institutional investors who have rules against buying low-priced stocks, and it can make the shares look like a speculative bet.
A higher price can improve the company's image, although the effect is cosmetic. The market often reads a reverse split as a sign of trouble, because it is typically used by companies whose shares have fallen sharply.
Prices sometimes drift lower again after the split if the business does not improve. A reverse split cannot fix weak earnings or heavy debt; it only changes the arithmetic of the share count.
For accounting and reporting, the company restates earnings per share and other per-share figures to reflect the new share count, so that past and future figures can be compared. Fractional shares, which arise when a holding does not divide evenly, are usually paid out in cash.
Investors should look at what a company does alongside the split. If the reverse split comes with a credible plan to cut costs, repair the balance sheet or raise fresh capital, it can be a sensible first step.
If it arrives alone, it may simply postpone the day when the market reaches a verdict on the business.
In practice
Real-world examples.
Example
A struggling shipping company sees its shares trade at $0.80 and receives a warning from its exchange. It announces a 1-for-10 reverse split to lift the price to $8.00 and stay listed.
Example
A small biotech firm wants to attract larger funds that will not buy stocks priced below $5. It completes a 1-for-5 reverse split, moving its price from $2 to $10, ahead of a new share offering. Management hopes the higher price will widen the pool of potential buyers.
Example
An investor holds 1,250 shares of a retailer that carries out a 1-for-100 reverse split. She is left with 12 shares and receives cash for the remaining quarter share, based on the new market price. Her broker sends a confirmation showing the share swap.
Formula
Calculation
New number of shares = Old number of shares / Split ratio
New share price = Old share price x Split ratio
Suppose a company has 50,000,000 shares trading at $0.80 each and carries out a 1-for-10 reverse split.
Market value before: 50,000,000 x $0.80 = $40,000,000
New number of shares: 50,000,000 / 10 = 5,000,000
New share price: $0.80 x 10 = $8.00
Market value after: 5,000,000 x $8.00 = $40,000,000
An investor who held 1,000 shares worth $800 now holds 100 shares worth $800. The total value is unchanged.Case study
Seen in the real world.
Brightwater Energy is a fictional company used in an illustrative scenario. Its shares fall to $0.60 after two years of losses, and the exchange warns that it will delist the stock if the price stays below $1 for another month.
The board proposes a 1-for-10 reverse split, shareholders approve it, and the price resets to about $6.00 with the share count dropping from 80,000,000 to 8,000,000. The market value stays near $48,000,000 on the day. Over the next quarter the price drifts down to $5.20 because the company still has not returned to profit, and the finance director reminds investors that the split was only a technical fix.
The finance director later wrote a short note for the board to explain what had and had not changed. The split had kept the shares on the exchange and improved how the stock was perceived by some funds, but it had not repaired the income statement. The board used the breathing space to agree a cost-cutting plan and to open talks with lenders about restructuring its debt.
Watch out
Common mistakes.
- Thinking a reverse split creates value. The total value of each holding is unchanged on the day, and the price can fall afterwards.
- Confusing a reverse split with a regular split. A regular split increases the number of shares and lowers the price; a reverse split does the opposite.
- Forgetting to restate per-share figures. Earnings per share and dividends per share have to be adjusted so that comparisons over time still make sense.
Questions
People also ask.
Is a reverse split bad news?
It is often a warning sign because it is commonly used by companies with falling share prices, but the reasons vary.
What happens to fractional shares?
They are usually paid out in cash at the post-split market value.
Do shareholders need to approve a reverse split?
Often yes, because it can require a change to the company's charter, but the exact requirements depend on local law.
