How reverse split round-ups work
A reverse stock split merges several existing shares into one. In a 1-for-20 split, every 20 shares become 1 share and the price per share goes up roughly 20x. Companies usually do this to get their share price back above an exchange's $1 minimum bid requirement.
What happens to leftover fractions?
If you hold a number of shares that doesn't divide evenly by the ratio, say 1 share in a 1-for-20 split, you'd be left with 1/20 of a share. Companies say in their filing how they handle that. The usual options:
- Rounded up: the fraction becomes one whole new share.
- Cash in lieu: you get paid cash for the fraction, usually at the post-split price.
- Rounded down: the fraction is dropped, sometimes with cash.
- Discretionary: the board decides later, or the filing allows several options.
Why people track round-ups
When a company rounds up, a holder of a single pre-split share can end up with one full post-split share worth many times more. That's why some investors watch these announcements closely. It is not risk-free:
- Brokers implement round-ups differently. Some deposit a fractional share, pay cash, apply it late, or skip it.
- Some brokers charge reorganization fees that can exceed the gain, and some restrict accounts that trade this way.
- Round-ups "at the participant level" are applied to the broker's total position at DTC, not to each customer, so the broker decides how to allocate them.
- The stock price can drop sharply around a reverse split. Companies can change the ratio, the date, or the policy, or cancel the split.
- Rounded-up shares can take days or weeks to arrive.
How this site gets its data
We search SEC EDGAR filings (8-K and 6-K) every day for reverse split and share consolidation announcements and read the ratio, the date and the fractional-share wording automatically. We only label a split "Rounds up" when the filing text says so. Anything ambiguous is marked Unverified or Not stated. We quote the exact sentence and link the filing so you can check it.
