Pro Rata Right
A pro-rata right is an investor's contractual right to buy enough of a company's future rounds to keep its percentage ownership from being diluted — an investor with 10% may take 10% of each new round. It is the mechanism through which early investors follow their winners, the term angels and seed funds fight hardest for, and the one new lead investors most often cut back, because the round they are pricing is only so large.
- Also known as
- Pro rata, Pre-emption right, Participation right
- Used at
- shareholders' agreements from seed onward; SAFE side letters; in listed companies the statutory version is pre-emption, which rights issues respect and placings are limited by
- Binding
- yes — a right to participate on the same terms as the new investors; not an obligation
- Typical scope
- "major investors" above a threshold (often 1–2% or a minimum invested) get it; smaller holders do not; it applies to equity financings and usually not to option grants, acquisitions or conversions
- Typical friction
- a new lead wants 20% of the company and the round is sized for that; if every existing holder takes its pro-rata, the lead's allocation shrinks, so leads negotiate the insiders' participation down or the round up
- Parties
- existing investors, founders (who prefer new money and new names), and the incoming lead
How a pro-rata right works in practice
A fund invests at the seed round for 12% and secures a pro-rata right. At the Series A the company raises €8m and the fund may take 12% of it — €960,000 — to hold its 12%; it takes it, from reserves. At the Series B, €20m, the pro-rata is €2.4m; the new lead wants €15m of the €20m and the other insiders also want their share, so the company either upsizes the round or asks the insiders to take less. The fund, which has €1.5m of reserves, takes that and is diluted slightly; a smaller angel without a pro-rata right is diluted fully.
The right's value is in the winners. In a company that fails, pro-rata is money added to a loss; in one that succeeds, it is the difference between a 12% stake and a 5% one at exit, which for a seed fund is the difference between a fund that returns 3× and one that returns 1×. Which is why seed funds insist on it, why they negotiate "super pro-rata" (the right to take more than their share) when they can, and why later leads cap or remove the rights of small holders whose participation is a nuisance.
In listed companies the same principle is statutory: existing shareholders must be offered new shares first unless they waive the right, which they do annually within limits — the reason a placing can be 10–20% of the capital and a larger raise needs a rights issue.
Example
A seed fund holds 12% of a payments fintech with pro-rata rights, and three angels hold 5% between them without. Series A: €8m at €32m pre-money; the fund takes €960,000 and stays at 12%; the angels dilute to 4%. Series B: €20m at €80m pre; the lead wants €16m; the fund's pro-rata is €2.4m but it agrees to €1.5m so the lead can have its allocation, diluting to 10.9%. Series C: €40m at €200m pre; the fund has no reserves, takes nothing, and dilutes to 9.1%. Exit at €500m: the fund's 9.1% is €45.5m on €3.5m invested — 13×. Had it held no pro-rata right and been diluted like the angels, its 12% would have become 6.4% and €32m; the right, exercised twice, was worth €13.5m.
Common mistakes
- Granting pro-rata rights to every angel, so the Series A round is oversubscribed by insiders before the lead arrives. - Taking pro-rata into every company regardless of prospects, because the right exists. - A lead investor sizing the round without asking who will exercise pro-rata. - Founders resenting insiders' pro-rata as "old money" when it is the cheapest signal of confidence the new lead can see. - Pro-rata rights that survive into a listed company's pre-emption disapplication, and complicate the first placing.
