What it means
When a company sells shares to the public, it must file a registration statement with the securities regulator describing the business, its finances and the risks of investing. Shares sold privately earlier, such as those held by founders and early investors, are usually restricted and cannot be freely resold until they are registered or an exemption applies.
A piggyback registration lets those holders travel along with the company's own filing. The right is normally written into an investor rights agreement or registration rights agreement at the time of the original investment.
It says that if the company decides to register shares for its own sale, it must notify the holders and give them a window, often a few weeks, to ask for their shares to be included. The company then adds those shares to the same document.
The main benefit is cost and timing. A registration is expensive because of legal, accounting, printing and filing fees, and a holder running a separate filing would carry that burden alone.
By joining an existing filing, the holder shares a document that already exists and usually pays only a modest share of the extra costs. The right is rarely unlimited.
The company's underwriters (the banks that sell the shares to investors) can decide that too many shares on offer would depress the price, and they can cut back the number of holder shares included. Agreements usually say the company's own shares come first, with holders trimmed in proportion to their holdings.
Piggyback registration differs from demand registration, where a holder can force the company to start a filing, and from shelf registration, where a company registers shares in advance to sell later. Piggyback rights are weaker than demand rights because they depend on the company choosing to register in the first place.
For that reason investors often negotiate several types of registration right together. For managers, the practical point is planning.
A finance lead should keep a list of who holds piggyback rights, the notice periods, the cutback rules and the expense-sharing terms, because missing a notice can breach the agreement. Later investors may hold rights that rank equally with or behind earlier holders, which affects who is trimmed first.
In practice
Real-world examples.
Example
A software company files to list on a stock exchange and notifies a venture fund that holds 500,000 shares with piggyback rights. The fund asks to include 100,000 shares in the offering. Those shares are sold at the same price as the company's own, and the fund bears its share of the selling costs.
Example
A privately held manufacturer plans a share offering to raise $40,000,000 for a new factory. A former executive holding restricted shares uses her piggyback rights to sell part of her stake in the same filing. She avoids the legal bill of arranging a separate sale.
Example
A biotech company raising $60,000,000 sees its underwriters recommend a smaller total offering because demand looks soft. An early seed investor with piggyback rights is cut back from 200,000 shares to 120,000 shares. The investor keeps the remaining shares for a later sale.
Case study
Seen in the real world.
Brightwater Analytics is a fictional software company, and this story is illustrative. Four years after a venture round, its board decided to prepare a public share offering and asked the finance director to list every holder with registration rights.
The finance director found that two early investors and one former co-founder held piggyback rights, each with a 20-day window to respond after notice. She sent formal notices the same week, because a late notice would have exposed the company to a claim for breaching the agreement. All three holders replied within the window, and together they asked to sell 450,000 shares.
The underwriters then advised that the offering could only absorb 300,000 holder shares without hurting the price. Under the cutback clause, each holder was reduced in proportion to the shares requested, and each was told in writing how the figure was reached. The illustrative lesson is that piggyback rights are valuable but conditional, and careful record keeping avoids disputes.
Watch out
Common mistakes.
- Assuming piggyback rights guarantee that every share a holder requests will be sold, when underwriters can cut the number back.
- Confusing piggyback rights with demand rights, which allow a holder to force the company to begin a registration.
- Ignoring the notice window, since many agreements treat silence as a decision not to participate.
Questions
People also ask.
Who pays the costs of a piggyback registration?
Usually the company pays the main filing costs, while each selling holder pays its own selling commissions and often its own legal advisers, but the agreement sets the exact split.
Does a piggyback right apply to every share offering?
No, agreements normally exclude registrations for employee share plans and for shares issued in an acquisition.
Is a piggyback right the same as a tag-along right?
No, a tag-along right lets a minority holder join a sale of control by another shareholder, while piggyback rights concern a company's own registration filing.
