When an institutional investor leads a primary round in a private company, the term sheet almost always includes a pro-rata right: the contractual right to participate in future financing rounds up to the investor's proportionate ownership. It is one of the most valuable rights attached to an early stake, because it lets an investor maintain their percentage as the cap table grows.

Secondary buyers frequently ask whether they inherit that right when they purchase membership interests or shares from a seller. In the overwhelming majority of cases, the answer is no — and understanding why changes how you should evaluate the economics of a secondary purchase.

Why pro-rata rights almost never transfer

Pro-rata rights are typically granted in an Investor Rights Agreement (IRA) or a Side Letter between the company and a specific named investor. The right belongs to the legal entity or individual named in that document — not to the underlying share class itself. When you buy shares or units in a secondary transaction, you receive the economic interest in those shares, but you do not automatically become a party to the IRA.

Companies guard these agreements carefully. Allowing unlimited transfer of pro-rata rights would give every secondary buyer a queue position in future rounds, which would complicate fundraising and dilute the company's ability to reserve allocation for lead investors in the next round. Most IRAs include an explicit non-assignability clause for exactly this reason.

There is a narrow exception: some IRAs allow transfer of rights to an affiliate or to a vehicle that the original investor controls. If you are buying through a fund-to-fund transaction or an institutional seller is transferring to a related SPV, it is worth reviewing the IRA language directly with counsel. But in a standard secondary marketplace transaction involving an employee seller or a small early investor, the right is gone the moment the original holder exits.

The share you buy in a secondary sale carries its economic strip — the right to receive proceeds on exit — but not the relationship rights the original investor negotiated at the table.

What this means for your expected returns

The loss of pro-rata rights matters most in companies that are still in high-growth, multi-round trajectories. If a company raises two or three additional primary rounds before an exit, an investor with pro-rata rights can maintain their ownership percentage and compound their position at each step. A secondary buyer starting with the same percentage cannot follow on, so dilution from those rounds is a one-way street.

Consider a simplified scenario. You buy a 0.10% stake in a private company at a $20 billion valuation. Over the next three years the company raises two rounds, each diluting existing holders by roughly 10%. An original investor with pro-rata rights participates and holds close to 0.10% at exit. You, as the secondary buyer who cannot follow on, hold closer to 0.081% by the time an exit event occurs. At a $50 billion exit valuation, that gap is material.

This dilution effect is one reason why sophisticated secondary buyers price in a discount to the last primary round — not just to reflect uncertainty or illiquidity, but to account for the asymmetry in future capital rights.

The SPV structure question

Buying through an SPV (special purpose vehicle) rather than via direct share transfer does not solve the pro-rata problem, but it does add another layer to examine. When you invest in an SPV that holds shares, you are a passive limited partner in a fund managed by a general partner. The GP may or may not have its own pro-rata rights, and even if it does, the GP has discretion about whether to exercise them and whether any follow-on economics flow to you as an LP.

Read the SPV operating agreement carefully. Some GPs carve out the right to run a follow-on SPV for the same issuer and charge fresh carry on that vehicle. Others simply allow dilution to happen. Neither approach is inherently improper, but you should understand which situation you are entering before you wire funds.

What to ask before signing

  • Does the seller hold any contractual pro-rata or follow-on rights? If so, do those rights transfer to a buyer under the IRA?
  • Has the company waived its right of first refusal (ROFR) on this transfer, and does that waiver affect any ancillary rights in the IRA?
  • If you are buying through an SPV, does the GP have independent pro-rata rights, and how are follow-on economics handled in the operating agreement?
  • What is the company's expected funding trajectory? If multiple future rounds are likely, how does your model hold up under 8–12% dilution per round?
  • Does the purchase price already reflect a meaningful discount to last round that compensates for the inability to maintain ownership percentage?

The rights that do transfer

Not everything falls away in a secondary transfer. Economic rights — the right to receive your proportionate share of proceeds in a liquidation, acquisition, or IPO — generally do travel with the shares, subject to any liquidation preferences stacked above you on the cap table. Information rights are more variable: some IRAs attach information rights (audited financials, quarterly updates) to the share class; others attach them to the named investor. The former transfer; the latter generally do not.

Registration rights — the right to have shares registered under the Securities Act ahead of or at an IPO — are another common IRA provision. Like pro-rata rights, these are typically personal to the original investor, though some IRAs allow transfer to buyers above a minimum ownership threshold. If registration rights matter to your post-IPO liquidity plan, verify their transferability explicitly before closing.

Economic rights tend to follow the shares. Relationship rights — pro-rata, information, registration — tend to stay with the original investor. That distinction is worth more than any single line item in the term sheet.

How to incorporate this into your diligence

Build two versions of your return model: one that assumes no dilution beyond the current cap table, and one that assumes two to three additional primary rounds of 8–10% each. If the investment still makes sense at the diluted ownership figure, the missing pro-rata right is priced in. If the investment only works at the undiluted figure, you need a steeper entry discount or a company that is genuinely close to an exit event.

Secondary due diligence is rarely about finding hidden information the market does not have. It is mostly about identifying the asymmetries that exist in plain sight — dilution from future rounds being one of the clearest — and pricing them correctly.
