A public company, also known as a publicly traded company, is a business entity whose ownership is represented by shares of stock that can be freely traded on public stock exchanges or over-the-counter markets. These companies are required to disclose regular financial and operational information to the public and regulatory bodies, allowing investors to access detailed data before making investment decisions.

Core Regulatory and Operational Significance

Public companies serve as a critical vehicle for raising large-scale capital from the general public, enabling expansion, research and development, and large-scale business operations. They also provide transparency requirements that help protect investor interests, though this also creates compliance costs and operational burdens for leadership teams.

Key Distinctions from Private Companies

Unlike private companies, public firms cannot limit their shareholder base, must hold regular shareholder meetings, and are subject to mandatory public filings. This difference creates both opportunities—broader access to capital—and challenges, such as short-term market pressure affecting long-term strategic planning.

Global Variations in Public Company Models

Regulatory frameworks vary by region: for example, the U.S. uses a disclosure-based system overseen by the SEC, while the EU has harmonized public company rules through directives like the Shareholder Rights Directive. Emerging markets often have simplified listing requirements to attract domestic and foreign investment.

A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets.[1][2] A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are private enterprises in the private sector, and "public" emphasizes their reporting and trading on the public markets.

Public companies are formed within the legal systems of particular states and therefore have associations and formal designations that are distinct and separate within the polity in which they reside. In the United States, for example, a public company is usually a type of corporation, though a corporation need not be a public company. In the United Kingdom, it is usually a public limited company (PLC). In France, it is a société anonyme (SA). In Germany, it is an Aktiengesellschaft (AG). While the general idea of a public company may be similar, the differences between types are meaningful and are at the core of international law disputes with regard to industry and trade.

Advantages

Publicly traded companies are able to raise funds and capital through the sale (in the primary market or secondary market) of shares of stock. Prior to their existence, it was very difficult to obtain large amounts of capital for private enterprises, as significant capital could come only from a smaller set of wealthy investors or banks willing to risk typically large investments. The profit on stock is gained in form of dividends or capital gains to the holders.

The financial media, analysts, and the public are able to access additional information about the business, since the business is commonly legally bound, and naturally motivated (so as to secure further capital), to disseminate public information regarding the financial status and future of the company to its many shareholders and the government.

Because many people have a vested interest in the company's success, the company may be more popular or recognizable than a private company.

The initial shareholders of the company are able to share risk by selling shares to the public. For example, the founder of Facebook, Mark Zuckerberg, owned 29.3% of the company's class A shares in 2013,[3] which gave him enough voting power to control the business and allowed Facebook to raise capital from and to distribute risk to the remaining shareholders. Facebook had been a privately held company prior to its initial public offering in 2012.[4]

If some shares are given to managers or other employees, potential conflicts of interest between employees and shareholders (an instance of principal–agent problem) will be remitted. As an example, in many tech companies, entry-level software engineers are given stock in the company upon being hired and so they become shareholders. Therefore, the engineers have a vested interest in the company succeeding financially and are incentivized to work harder and more diligently to ensure that success.

Public companies have fiduciary duty to their shareholders, in addition to the directors' fiduciary duty to the company itself.

Disadvantages

Many stock exchanges require that publicly traded companies have their accounts regularly audited by outside auditors and then publish the accounts to their shareholders. Besides the cost, that may make useful information available to competitors. Various other annual and quarterly reports are also required by law. In the United States, the Sarbanes–Oxley Act imposes additional requirements. The requirement for audited books is not imposed by the exchange known as OTC Pink.[5][6] The shares may be maliciously held by outside shareholders and the original founders or owners may lose benefits and control. The principal–agent problem, or the agency problem is a key weakness of public companies. The separation of a company's ownership and control is especially prevalent in such countries as the United Kingdom and the United States.[7][8]

Privatization

In corporate privatization, more often called "going private," a group of private investors or another company that is privately held can buy out the shareholders of a public company, taking the company off the public markets. That is typically done through a leveraged buyout and occurs when the buyers believe the securities have been undervalued by investors. In some cases, public companies that are in severe financial distress may also approach a private company or companies to take over ownership and management of the company. One way of doing so would be to make a rights issue designed to enable the new investor to acquire a supermajority. With a supermajority, the company could then be relisted, or privatized.

Alternatively, a publicly traded company may be purchased by one or more other publicly traded companies, with the target company becoming either a subsidiary or joint venture of the purchaser(s), or ceasing to exist as a separate entity, its former shareholders receiving compensation in the form of either cash, shares in the purchasing company or a combination of both. When the compensation is primarily shares then the deal is often considered a merger. Subsidiaries and joint ventures can also be created de novo, which often happens in the financial sector. Subsidiaries and joint ventures of publicly traded companies are not generally considered to be privately held companies (even though they themselves are not publicly traded) and are generally subject to the same reporting requirements as publicly traded companies. Finally, shares in subsidiaries and joint ventures can be (re)-offered to the public at any time. Firms that are sold in this manner are called spin-offs.

Most industrialized jurisdictions have enacted laws and regulations that detail the steps that prospective owners (public or private) must undertake if they wish to take over a publicly traded corporation. That often entails the would-be buyer(s) making a formal offer for each share of the company to shareholders.
