Piggyback Registration Rights

Piggyback Registration Rights are contractual rights allowing eligible holders to request inclusion of their Registrable Securities in a qualifying registration or registered offering that the issuer or another holder is already pursuing.

Updated 2026-09-02 · Foundation

How it works

Unlike Demand Registration Rights, piggyback rights normally do not let the holder start the registration process. Instead, when the issuer proposes a qualifying offering, it gives covered holders notice and a period to elect participation. The agreement can exclude forms such as S-8 or S-4, employee-plan registrations, business combinations or other specified transactions. Underwriters can also reduce holder allocations when market conditions require a smaller offering.

Another registration creates the opportunity

The issuer or another qualifying holder initiates the registration, and the piggyback holder elects whether to join.

Notice and election periods can be short

Agreements commonly give only a few business days to request inclusion after the company provides notice.

Excluded registrations matter

Employee benefit plans, merger forms, exchange offers and other specialized filings can fall outside the piggyback right.

Underwriter cutbacks can reduce allocations

If the offering cannot support all requested securities, priority rules determine which shares remain included.

Worked example: secondary cutback

Holders request 10 million secondary shares, but the underwriter recommends only 4 million. The agreement’s priority formula determines each holder’s final allocation.

Why piggyback rights are weaker than demand rights

The holder benefits from an existing registration but generally cannot force the company to create the transaction in the first place.

Common mistakes

Calling piggyback rights demand rights; assuming inclusion is guaranteed; ignoring excluded forms; and assuming the holder can stop the issuer from abandoning the offering.

Example

A company plans a public offering of common stock and sends notice to holders with Piggyback Registration Rights. A holder requests inclusion of 3 million Registrable Securities, but the lead underwriter reduces secondary shares across participating holders to keep the offering at the desired size.

Professional note

Piggyback rights create participation access, not control over timing. The issuer can often abandon its own offering, which can eliminate the piggyback opportunity.
