The Mechanics
In a reverse stock split, a company combines its existing shares into fewer shares. In a one for ten split, every ten shares become one. A holder of 10,000 shares ends up with 1,000, and in theory the share price rises tenfold on the same day.
Nothing about the business changes. Market value, cash, debt and each holder's percentage ownership stay the same at the moment of the split. The investor education site of the SEC notes one exception: some small holders may be cashed out for fractional shares rather than receiving part of a share.

| Before | After | |
|---|---|---|
| Shares outstanding | 100,000,000 | 10,000,000 |
| Share price | $0.80 | $8.00 |
| Market value | $80,000,000 | $80,000,000 |
| A holder of 10,000 shares | 10,000 shares, $8,000 | 1,000 shares, $8,000 |

Why Companies Do It
According to Investor.gov, companies usually reverse split to raise the trading price, often because the price is too low to attract investors or to regain compliance with an exchange's minimum bid price requirement. For microcaps, the second reason is the common one.
Both major US exchanges require a $1.00 minimum price. On Nasdaq, a deficiency arises when a stock closes below $1.00 for 30 consecutive business days. The company generally gets 180 days to cure it and may get a second 180 day period. On the NYSE, the test is an average closing price below $1.00 over 30 consecutive trading days, with a six month cure period.

The Rules Got Stricter in 2025
Exchanges tightened the rules on companies that reverse split repeatedly. Under amendments approved in January 2025:
- Nasdaq: a company that falls below $1.00 gets no compliance period if it effected a reverse split in the prior year. A 2020 rule already removed the compliance period after reverse splits with a cumulative ratio of 250 to 1 or more over two years.
- NYSE: no compliance period after a reverse split in the past year, or after splits with a cumulative ratio of 200 to 1 or more over two years. The exchange moves straight to suspension and delisting.
- Nasdaq notice: since January 30, 2025, companies must notify Nasdaq at least 10 calendar days before a split takes effect and disclose it publicly at least two business days before.
In practice, a company that reverse splits and then slips back under $1.00 within a year now faces delisting proceedings rather than a new cure period.

What a Reverse Split Can Signal
The split is arithmetic. The reason behind it is the information. Questions worth asking:
- Why did the price fall below $1? A price under $1 usually follows either a long decline in the business or repeated share issuance. The 10-Q cover page shows which: compare the share count with a year earlier.
- Is this the first split? A company on its second or third reverse split in a few years has been issuing shares faster than it creates value. The new exchange rules exist because of that pattern.
- What happens to authorized shares? If a company reduces outstanding shares but keeps the number of authorized shares the same, it has more room to issue new stock afterwards. The proxy statement or 8-K describing the split will say.
- Is a financing attached? A split followed shortly by an offering is common, because a higher share price makes it easier to sell new shares.
Where to Find It in the Filings
Investor.gov notes that companies filing with the SEC may disclose a reverse split on Forms 8-K, 10-Q or 10-K, and may need a proxy statement on Schedule 14A if shareholders must approve it. Whether shareholder approval is needed depends on state law and the company's charter and bylaws. On a stock chart, past prices are usually adjusted for the split, so a history of reverse splits can hide in plain sight. The filing record does not hide it.

Frequently Asked Questions
Does a Reverse Stock Split Change What My Shares Are Worth?
Not at the moment it happens. You hold fewer shares at a higher price, and your ownership percentage is the same, apart from any cash paid for fractional shares. What the shares are worth afterwards depends on how the market prices the company.
Why Do Companies Do Reverse Splits?
Most often to raise the share price above an exchange's $1.00 minimum bid requirement, or to make the stock more attractive to investors who avoid low priced shares.
Can a Company Do Several Reverse Splits?
It can, but since January 2025 both Nasdaq and the NYSE deny a compliance period to companies that fall below $1.00 within a year of a reverse split, or after large cumulative splits over two years.
Where Is a Reverse Split Disclosed?
Usually in a Form 8-K, and in a proxy statement if shareholders vote on it. The next 10-Q or 10-K will reflect the new share count.
