What Does It Mean to Go Public? Selling Shares and Accepting the Consequences

A listing makes a company's shares tradeable on a public market, which requires satisfying the exchange's admission rules and the relevant securities regulation. The company publishes a prospectus describing its business, finances and risks in considerable detail, which carries legal liability if it misleads. Shares are offered, either newly issued to raise capital for the company or sold by existing holders, at a price set through a process involving investment banks assessing demand. From admission onward the company is subject to continuing obligations, and its shares have a public price that changes daily and that everybody can see, which is itself a substantial change in how the business is experienced by everybody in it.

The trade is real and both sides of it are substantial:

• •Access to capital from a broad pool of investors, repeatedly rather than only once
• •A market price, which allows shares to be used as currency for acquisitions and as employee compensation
• •Liquidity for existing owners, who can sell without finding a buyer privately
• •Continuing disclosure of results, of significant events and of directors' dealings
• •Regulatory and audit costs that are substantial and largely fixed regardless of size
• •Pressure towards short-term results, since performance is reported and judged quarterly

The number of listed companies in several major markets has fallen substantially over the past two decades, and the reasons are identifiable. Private capital has become abundant, so a company that would once have needed a public market to fund growth can raise very large sums privately and stay private far longer. Regulatory obligations increased after accounting scandals around 2001 and after the financial crisis, raising the fixed cost. Being private avoids disclosure that competitors read. Founders retain control, which public markets and activist investors erode. And acquisitions have removed listed companies faster than new listings replace them. The consequence is that ordinary investors have less access to the growth of companies that stay private, which is a genuine policy concern.

A listed company has a price, and what that price represents is worth stating carefully. In principle it reflects the market's collective estimate of the future cash the company will generate, discounted for time and risk, which is a statement about the future rather than a measurement of anything present. In practice it also reflects sentiment, liquidity, index membership, the availability of alternatives and the flows of money into and out of funds, none of which concerns the business at all. That is why a company's price can move sharply on no news about the company. It is also why the price is a poor guide to whether a business is well run and an excellent guide to what somebody would pay for it today, which are different questions.

Companies wanting some of the benefits without the whole package have several routes. Direct listing places existing shares on a market without raising new capital or using banks to set a price, which several large technology companies chose. Merging with an already listed shell company achieves a listing faster and with less scrutiny, an arrangement that boomed around 2020 and then collapsed amid poor outcomes and regulatory attention. Junior markets with lighter obligations exist in several countries for smaller companies. Dual class share structures allow founders to retain voting control while selling economic ownership, which major indices resisted and then accommodated. Each of these trades some protection for investors against some convenience for issuers, which is the recurring tension in the whole area.

Listing makes shares tradeable in exchange for publishing a prospectus carrying legal liability and accepting continuing disclosure, audit and regulatory costs that are largely fixed. It buys repeated access to capital, a usable share price and liquidity for existing owners. Abundant private capital and rising obligations have reduced the number of listed companies substantially over two decades.
