Glossary · Equity and dilution · Updated
Pro rata rights let an existing investor participate in later rounds up to their current ownership, so they are not diluted. It is a right to participate, never an obligation, and how a fund uses it is read closely by incoming investors.
For the investor the right is valuable. It lets them put more money into their best holdings, the ones whose trajectory they already know from the inside. That is exactly where fund performance concentrates, which is why follow-on reserves are often half the size of a fund.
For the company the cost is less visible: it takes up space in later rounds. If every existing investor exercises on an oversubscribed round, there is not enough left for the new fund you wanted. Negotiating with your own shareholders to free up allocation is common.
Exercising is a signal. A fund that does not follow on sends a message to incoming investors, who will ask why. The reasons can be entirely neutral, such as a fund at the end of its investment period, but you need to be able to explain it clearly.
Example: exercising and declining pro rata rights
A fund holds 15%. The company raises €4M at a €20M post-money valuation.
| Investor's current holding | 15% |
|---|---|
| New round size | €4,000,000 |
| Post-money valuation | €20,000,000 |
| Round dilution | 20% |
| Amount reserved under pro rata | 15% × €4M = €600,000 |
| If they exercise in full | they keep 15% |
| If they decline | 15% × 80% = 12% |
| Ownership lost | 3 points |
Three points of equity in a single round, for a €600,000 cheque. That is the trade a fund reruns at every round, and its answer says a lot about what it really thinks of the company.
The common mistake
Granting pro rata rights to every small holder in a pre-seed round. You end up with twenty people holding a contractual right over every future round, which complicates allocation and deters funds that want a meaningful position.
Frequently asked questions
What are pro rata rights?+
The right of an existing investor to subscribe to the next round up to their current percentage in order to maintain their holding. On a €4M round, a 15% shareholder can subscribe €600,000. It is an option, not an obligation.
What does it mean when an investor declines their pro rata?+
Incoming investors often read it as a negative signal and will ask. Neutral explanations exist, notably a fund at the end of its investment period or with exhausted reserves, but you need to give them without hesitation.
