Pro-rata rights

Investor's right to participate in future rounds to maintain ownership percentage.

Definition
Pro-rata rights are an investor's contractual right to participate in future financing rounds, up to the amount needed to maintain their existing percentage of ownership. They protect investors from dilution by giving them first option to invest before new outside investors come in.

How pro-rata rights work in practice

A Series A investor holds 15% of a company. The company raises a Series B that would issue 25% new equity. Without pro-rata rights, the Series A investor would be diluted to 11.25%. With pro-rata rights, the investor can purchase enough Series B shares to maintain their 15% position (or close to it, depending on the exact mechanism).

  • Mechanism is contractual, typically in the investor rights agreement or the convertible/SAFE terms
  • Typically granted to major investors only (above a threshold like $1M invested or 5% ownership)
  • Not all SAFE and convertible note holders get pro-rata, but it's a common ask
  • Investor can choose to participate (in full or partially) or pass — it's a right, not an obligation

Pro-rata vs super pro-rata

Standard pro-rata lets an investor maintain their current percentage. 'Super pro-rata' (uncommon, occasionally negotiated by lead investors) lets them increase their stake by buying more than their pro-rata share. Most term sheets resist super pro-rata because it constrains the company's ability to bring in new strategic investors.
