Pro Rata Rights

The right of existing investors to invest in future rounds to maintain their ownership percentage.

Full Definition

Pro rata rights give existing investors the right (but not obligation) to participate in future funding rounds to maintain their proportional ownership in the company. This is a valuable protection against dilution.

How Pro Rata Works

If an investor owns 10% of a company and the company raises a new round, pro rata rights allow them to invest enough in the new round to maintain their 10% ownership stake.

Significance

  • Protects investors from dilution in successful companies
  • Common in seed and Series A term sheets
  • Sometimes called "participation rights" or "preemptive rights"
  • Major pro rata rights can indicate investor confidence
  • Can create challenges if too many investors exercise pro rata in oversubscribed rounds

Real-World Example

A seed investor with pro rata rights who owns 8% exercises their right to invest $2M in the Series A to maintain their 8% stake.
