Pro-Rata Rights

Pro-Rata Rights

Quick Facts

  • Also called: Participation rights, pre-emptive rights
  • Purpose: Allows investors to maintain ownership percentage in future rounds
  • Standard: Typically granted to institutional investors (Series A+)
  • Variation: Super pro-rata (right to increase ownership)

Pro-rata rights give existing investors the right (but not obligation) to participate in future financing rounds to maintain their ownership percentage. If an investor owns 10% and the company raises more money, pro-rata rights let them invest enough to keep their 10% stake.

In Plain English

Pro-rata rights are like a "first dibs" clause for investors. When you raise your next round, your existing investors can say "we want to invest more to keep our same percentage." Without pro-rata rights, every new round would dilute them. With pro-rata rights, they can choose to avoid dilution by writing another check.

How It Works

Example: Series A investor with pro-rata rights

  1. Series A: Investor puts in $2M for 20% ownership
  2. Series B: Company raising $10M at $50M pre-money valuation
  3. Pro-rata calculation: Investor can invest 20% × $10M = $2M
  4. Result: If they invest $2M, they maintain ~20% ownership

Without participating, their 20% would be diluted to ~16.7% after the Series B.

Pro-Rata Calculation

The formula is straightforward:

Pro-Rata Amount = Current Ownership % × New Round Size

If you own 15% and the company is raising $20M:

Pro-Rata Amount = 15% × $20M = $3M

Who Gets Pro-Rata Rights

Investor TypeTypically Gets Pro-Rata?
Institutional VCsYes (standard)
Angel investorsSometimes (negotiated)
Strategic investorsUsually
SAFE/Note holdersRarely (until conversion)
EmployeesNo

Pro-rata rights are nearly universal in institutional venture deals but less common for small angel checks.

Major vs. Minor Investors

Many term sheets limit pro-rata rights to "major investors"—those exceeding a minimum ownership threshold:

  • Series A: Major investor = owns 5%+ of preferred
  • Series B+: Threshold may increase to 3-5% of total equity
  • Below threshold: May lose pro-rata rights or need lead investor approval

This prevents dozens of small investors from claiming pro-rata in future rounds.

Super Pro-Rata Rights

Some investors negotiate super pro-rata rights—the ability to invest more than their ownership percentage in future rounds. This is aggressive and typically resisted by founders because:

  • It limits space for new investors
  • It can signal the investor doesn't believe in competitive rounds
  • It reduces founder leverage in future negotiations

The Pro-Rata "Problem"

When companies perform well, everyone wants to exercise pro-rata:

  1. Oversubscribed rounds: Too much investor demand
  2. Existing investors demand their pro-rata allocation
  3. New lead investor wants meaningful ownership
  4. Conflict arises: Not enough room for everyone

Common solutions:

  • New lead takes smaller position than desired
  • Some existing investors voluntarily waive pro-rata
  • Company increases round size
  • Secondary sales create room

When Investors Don't Exercise Pro-Rata

Investors may pass on pro-rata for several reasons:

  • Fund constraints: No reserves left for follow-ons
  • Valuation concerns: Believe the price is too high
  • Signaling risk: Passing can signal lack of confidence
  • Portfolio construction: Need to diversify across companies

Not exercising pro-rata can be a red flag to new investors ("why aren't the existing investors investing more?").

Pay-to-Play Provisions

Some term sheets include pay-to-play: investors who don't participate in future rounds lose certain rights (conversion to common, loss of anti-dilution, etc.). This pressures investors to continue supporting the company.

Pro-Rata vs. Anti-Dilution

Pro-rata lets you choose to avoid dilution; anti-dilution automatically adjusts in certain scenarios.

Practical Takeaways

For founders: Pro-rata rights are standard for institutional investors and generally benign. Watch out for super pro-rata demands, which can limit your options in future rounds. Keep pro-rata limited to major investors to avoid complexity.

For investors: Always negotiate pro-rata rights if you believe in the company long-term. Understand the major investor threshold. Reserve capital in your fund for follow-ons—not exercising pro-rata can damage your reputation and signal lack of conviction.
