Pre-emptive rights give existing shareholders the first opportunity to buy newly issued shares, in proportion to their current holding, before those shares are offered to outsiders. By participating, a shareholder can maintain their ownership percentage instead of being diluted by the new issuance.
Why it matters to you
In private companies, pre-emptive rights are usually reserved for major investors through the shareholders' agreement — small retail holders often do not get them. Knowing whether you have them tells you whether you can defend your stake when the company raises its next round, or whether each round will steadily shrink your percentage.
Example: An institutional investor used its pre-emptive right to buy into a new round and hold its 12% stake, while ordinary unlisted holders without the right saw their percentage fall.
