What it means
The holder of escrowed shares usually keeps the economic rights that come with them, such as dividends and voting, but loses the right to sell. A registrar, transfer agent or trustee holds the certificates or applies an electronic restriction, and only lifts it when the release conditions in the escrow deed are satisfied.
Escrowed shares exist because markets and buyers price commitment. If a founder can dump their entire stake the week after a listing, new investors will demand a lower price to compensate for that risk, so voluntary or exchange-mandated escrow supports the valuation.
Releases are normally staged over time or tied to performance milestones. A typical structure releases a quarter of the escrowed block every six months over two years, while a milestone structure might release shares only once revenue or a regulatory approval target has been hit.
Escrowed shares also affect the free float, which is the number of shares actually available to trade. A large escrowed block makes a stock thinner and more volatile, and analysts watch upcoming release dates because a wave of newly tradable shares can weigh on the price.
The concept overlaps with, but is not identical to, a lock-up. A lock-up is a contractual promise not to sell, whereas escrow puts the shares physically or electronically beyond reach, which makes it harder to breach and easier for an exchange to police.
Escrowed shares appear on the other side of acquisitions too, where a buyer pays part of the price in its own stock and locks it up as security for warranty claims. Cancelling escrowed consideration shares is often far simpler for a buyer than suing the sellers for cash, so the structure quietly strengthens the buyer's position while still giving the sellers a stake in the combined business.
In practice
Real-world examples.
Example
A mining exploration company lists on a growth market and the exchange requires the two founders to place 60% of their holdings in escrow for two years. Institutional buyers accept the offer price partly because the founders cannot exit before the drilling results are known.
Example
A private equity buyer acquires a services business and pays 20% of the price in its own shares, escrowed for 18 months. If a warranty claim arises, the buyer can cancel escrowed shares instead of chasing the sellers for cash.
Example
A biotechnology company issues shares to a university in exchange for a patent licence, with release tied to milestones. The university receives its first tranche only when the compound clears an early-stage trial, which aligns the licensor with the outcome rather than the signing.
Formula
Calculation
Escrowed shares = shares held x escrow percentage, and free float = total shares outstanding - escrowed shares. Suppose a founder holds 4,000,000 shares in a company with 10,000,000 shares outstanding, and the listing rules put 60% of the founder's stake into escrow: 4,000,000 x 0.60 = 2,400,000 escrowed shares. Free float is therefore 10,000,000 - 2,400,000 = 7,600,000 shares, or 7,600,000 / 10,000,000 = 76% of the company. The escrow deed releases 25% of the block every six months over 24 months, which is 2,400,000 x 0.25 = 600,000 shares per release, and at a $3.50 share price each tranche is worth 600,000 x $3.50 = $2,100,000.Case study
Seen in the real world.
This illustrative case involves a fictional company, Northgate Analytics. When it listed, the two founders between them held 4,000,000 of the 10,000,000 shares outstanding, and the exchange required 2,400,000 of those shares to be escrowed for two years with releases every six months.
Six months after the listing the share price had risen from the $2.80 offer price to $3.50, and the first tranche of 600,000 shares became tradable, worth $2,100,000. One founder sold half of her released tranche and kept the rest, while the other sold nothing, and the market barely moved because the release had been disclosed in the prospectus.
The finance director's main lesson was about communication rather than mechanics. Because Northgate published the escrow release calendar and each founder's intentions in advance, the illustrative story ended with an orderly market rather than the price shock that surprise selling can cause.
Watch out
Common mistakes.
- Assuming escrowed shares do not count when calculating earnings per share. They are issued and outstanding, so they sit in the share count even though they cannot be traded.
- Confusing escrow with forfeiture. Escrowed shares are already owned; unvested shares under a vesting schedule can still be lost entirely.
- Ignoring release dates when modelling share price support. A block coming free can add meaningful selling pressure in an otherwise quiet stock.
Questions
People also ask.
Do escrowed shares still receive dividends?
In most structures yes, and they usually carry voting rights too, because only the right to sell is suspended.
Can escrowed shares be used as loan collateral?
Normally not, since the whole point is that they cannot be transferred or pledged while the escrow lasts.
Who decides the escrow period?
Either the stock exchange rulebook, the underwriters as a condition of the offer, or the buyer in an acquisition, depending on the situation.
