Pro-rata rights explained: how investors keep their stake

A pro-rata right lets an existing investor buy enough of a future round to keep its percentage ownership from falling. It is a right, not an obligation: the investor can take all, part or none of its allocation. In Indian shareholders' agreements it often appears as a pre-emptive right.

How the maths works

To keep its stake, an investor needs to buy the same percentage of the new round as it already owns. An investor with 10% of the company takes 10% of the new shares, which costs 10% of the round.

Term sheets commonly measure ownership for this purpose on a fully diluted basis, counting options and convertible instruments. Check the definition, because it changes the number.

Worked example

Illustrative figures. A seed investor holds 1,00,000 of a startup's 10,00,000 fully diluted shares: 10%. The company raises a ₹30 crore Series A at a ₹120 crore pre-money valuation.

The price per share is ₹120 crore ÷ 10,00,000 = ₹1,200, so the round issues ₹30 crore ÷ ₹1,200 = 2,50,000 new shares, for a total of 12,50,000.

If the seed investor does nothing, it holds 1,00,000 ÷ 12,50,000 = 8%. To stay at 10%, it needs 10% of the new shares: 25,000 shares × ₹1,200 = ₹3 crore. It then holds 1,25,000 ÷ 12,50,000 = 10%.

Unless the round is enlarged, that ₹3 crore comes out of the ₹30 crore, so the new lead invests ₹27 crore and gets 2,25,000 ÷ 12,50,000 = 18% instead of 20%. That is why leads look closely at existing investors' pro-rata rights.

Super pro-rata

A super pro-rata right lets an investor buy more than its pro-rata share, increasing its stake in later rounds. It is less common and can make it harder to bring in a new lead, who usually wants a meaningful stake of its own. Founders generally resist it, or limit it to one round or a fixed amount.

Major investor thresholds

Pro-rata rights are often limited to "major investors": holders who invested at least a set amount or own at least a set number of shares. The threshold is negotiated in the term sheet. It keeps the right with investors who can follow on meaningfully, and stops dozens of small holders from claiming slices of every round.

Other common limits are a "use it or lose it" clause that removes the right from investors who skip a round, carve-outs for shares issued to employees or in acquisitions, and an end to the right at an IPO.

Pro-rata in India

Indian venture rounds usually issue new shares to selected investors through a preferential allotment approved by shareholders, so an investor's pro-rata right comes from the SHA and is written into the articles of association. Before each new round, existing investors either take up their entitlement or sign a waiver, which is a routine part of closing. For foreign investors, any shares taken up must follow foreign-exchange pricing and reporting rules.

Why founders should care

  • Signalling: if an existing investor with pro-rata declines to invest, new investors will ask why.
  • Room for the lead: generous pro-rata rights can leave too little of the round for a new lead.
  • Friendly money: insiders taking up their pro-rata can anchor a round or fund a bridge.
  • Side letters: SAFE investors sometimes get pro-rata rights through a side letter, so track these alongside the cap table.

Questions founders ask

Are pro-rata rights an obligation to invest?

No. They give the investor the option to invest its share of a future round. It can take all, part or none.

Do angel investors get pro-rata rights?

Sometimes. Many term sheets give the right only to major investors above a threshold, so smaller angels may not have it unless it is agreed separately.

What happens to pro-rata that is not taken up?

It usually goes back into the round for the lead or other investors. Some agreements let the investors who did take up their share buy the unused part, called an over-allotment.

Is pro-rata calculated on a fully diluted basis?

Usually, but definitions vary. Some count only issued shares or only preference shares, so read how the term sheet defines ownership.

Do pro-rata rights end at an IPO?

They usually end at an IPO, and often on a sale of the company. Some agreements also remove them from investors who skip a round.
