Initial Public Offering (IPO)
Last updated 17 July 2026
An initial public offering, or IPO, is the first offering of a company's shares to public investors alongside admission to trading on a stock exchange. The company usually issues new shares to raise capital, existing holders may sell some shares, or both. Underwriters help structure, market, price, and distribute the offering under the rules of the relevant market.
For a founding family, an IPO changes how ownership is valued and governed. Shares gain a quoted price and may become more tradeable, while the company takes on public disclosure, market scrutiny, and continuing obligations. The family can remain a controlling shareholder after the listing.
Why it matters for family offices
An IPO can create liquidity and a visible net worth, but it does not make a concentrated holding equivalent to cash. Founders and early investors are often subject to contractual lock-ups, securities-law restrictions, insider policies, and trading windows. The exact restrictions vary by offering and jurisdiction, and selling a large position can affect the market.
Planning spans tax, estate structures, philanthropy, custody, borrowing, diversification, and personal security. Actions involving shares must be coordinated before sensitive information or transaction restrictions limit the available choices. The office also prepares for price volatility and separates the company's needs from the family's portfolio needs.
How it shows up in practice
Suppose a family owns 40 percent of a company before its IPO and sells only a small portion in the offering. The remaining shares receive a public price, increasing the reported value of family wealth, but most are locked up for an agreed period and later sales must follow applicable rules. The family office records unrestricted, restricted, and pledged shares separately.
It builds a cash plan using only actual proceeds, coordinates tax payments, and presents diversification scenarios to the investment committee. When the lock-up expires, the family does not sell automatically. It weighs control, market liquidity, concentration, and family objectives under professional advice. The IPO is a transition in ownership and governance, not a one-day conversion of the entire stake into cash.
Related terms
Direct Listing
A route to the public markets in which a company lists existing shares on an exchange without raising new capital or using underwriters. Direct listings avoid dilution and underwriting fees and usually skip the traditional lock-up, giving existing holders immediate liquidity. They suit well-known companies whose shareholders, including founders and family investors, primarily want tradability.
Liquidity Event
A transaction, such as the sale of a family business, an IPO, or a large dividend, that converts illiquid ownership into investable cash. Liquidity events are often the moment a family office is founded, as families suddenly face the task of managing substantial financial capital. They trigger major decisions on structuring, allocation, and governance.
Public Markets
Exchanges and regulated venues where securities such as listed stocks and bonds are bought and sold, with continuous pricing and deep liquidity. Public markets form the liquid core of most family portfolios and the benchmark against which private investments are judged. Positions are visible on custodial statements, making them the easiest part of family wealth to aggregate and report.
Lock-Up
A period during which an investor cannot withdraw capital from a fund, standard in hedge funds and inherent in private equity's ten-plus-year structure. Lock-ups let managers pursue strategies without forced selling but concentrate liquidity risk with the investor. Family offices map lock-ups across all funds to understand how much of the portfolio is truly accessible at any time.
Concentration Risk
The risk that arises when a large share of a family's wealth is tied to a single asset, company, sector, or currency, often the original family business. While concentration frequently created the wealth, it can also destroy it. Measuring true concentration requires looking through all entities and accounts to the underlying exposures.
