Welcome to Wall Street.© lucky-photographer—iStock/Getty ImagesApple. Microsoft. IBM. Amazon. The legends of American business are pretty much all publicly traded companies—and at one time, they were all quite small.

　　The traditional way for companies to get listed and begin trading on a stock exchange is via an initial public offering (IPO), a process that introduces the company, shares its financial information, and invites orders from the investing public. An IPO can help a company attract a wide pool of capital and make a big splash in the market.

　　It’s not the only way to go public, nor is it the only way for founders to cash out. In addition to IPOs, businesses can go public through a direct listing, merger with a special purpose acquisition company (SPAC), or by selling the business to a public company.

　　Why should a company go public?Being publicly traded can be a huge advantage for a company. First, because shares of stock represent a slice of ownership in the company, a public listing makes it easy to change shareholders without affecting day-to-day management. The listing can also raise the company’s visibility in financial media and the marketplace in general.

　　After the company goes public, it must comply with exchange listing requirements and government regulations, including filing regular financial reports with the Securities and Exchange Commission (SEC). These reports become public information, so anyone can access them. Having the company’s financials—and its market capitalization—on public display at all times can make it easier (and cheaper) for the company to issue bonds and other debt securities.

　　But it’s typically more expensive to be a publicly held company. When a company prepares for an IPO, executive teams need to budget for the legal, accounting, and public relations services to support it. Remember: It’s a compliance no-no for any company insider to distribute material information in a nonpublic setting.

　　Deciding the terms and selecting funding partnersThe IPO process can take as long as a year or more. It starts with the company’s board of directors deciding to go public, then setting up the internal and external teams to manage the process. The firm’s accountants and lawyers have to be involved, along with any venture capital partners and others involved in the pre-IPO funding process, as there are several decisions that need to be hammered out:

　　How much of the company’s enterprise value should be tendered in an IPO? Typically, a company will issue shares at 40% to 50% of its value, but it may be more or less, depending on how much capital the current owners want to raise and how much ownership they want to keep. What do the current owners wish to receive in return for tendering their shares in the IPO? Some private investors prefer to cash out on the IPO, while others—particularly the founder(s)—may want to hang on to help guide the company after the transition. Plus, some creditors who have loaned the company money along the way may have structured their investments as convertible bonds. That might affect the share count, and thus the value of the IPO. What lockouts or other restrictions should be placed on existing owners’ shares? Frequently, after an IPO, insiders’ ownership stakes are converted into shares, but those shares can’t be sold until after a “lockout period” of perhaps six months or a year. Should employees be granted shares? One benefit of working for a publicly held company is the potential to receive stock options and/or other incentive compensation. Plus, during the transition, it’s important to demonstrate to investors that the company has a robust employee retention plan in place.Once these and other pre-IPO decisions have been made, the current owners will hire the investment bank that will lead the underwriting process, and later, the transition from private to public. Most companies hire more than one bank, but one has the primary responsibility for getting the deal done.

　　Filing SEC Form S-1Once the team is in place, its members work on writing the registration statement, which consists of a  prospectus—the “selling document” that’s required by the SEC for any entity offering securities—along with other information required by the SEC to help with the review process.

　　Although some smaller and emerging companies may opt for a less formal and more streamlined filing process, the standard registration filing is through SEC Form S-1. The S-1 covers every aspect of the company’s business that investors would need to understand to make an investment decision, including:

　　Financial statementsA business descriptionA market analysisA risk analysisBiographies of board members and key employeesRed herrings and road showsThe SEC reviews the registration documents and either signs off on them or requests revisions. Before the deal closes, the S-1 is considered to be a preliminary document, and it must carry a warning—printed in red—that information is subject to change. Because of the mandatory red warning label, preliminary S-1s are often called red herrings.

　　When the SEC approves the S-1 for distribution, the investment bank organizes a road show. It usually creates a video presentation that can be viewed by any prospective investor, as well as remarks that the company’s CEO and CFO can give in person. The underwriters organize group meetings in financial centers, as well as one-on-one meetings with interested institutional investors.

　　Assuming the road show and other pre-IPO buzz have generated significant interest in the company’s shares, the bankers will begin soliciting orders, asking interested investors to indicate how many shares they might be willing to buy and at what price. At this point, the bankers are “putting together a book”—they’re deciding how to structure the IPO share count and offering price to maximize the value of the IPO.

　　If demand for shares outstrips the company’s interest in selling, the deal is said to be oversubscribed. This is good for the company, because it can then raise more money at a lower cost. Of course, IPOs are often undersubscribed, and sometimes the deal is so undersubscribed that it can’t close at all.

　　If the IPO does close, the company will issue a final prospectus that includes the number of shares issued, the price of those shares, and total amount of money raised.

　　Alternatives to initial public offeringsBecause an IPO is expensive, a lot of work, and not guaranteed to raise money, many companies that want to go public look for alternatives. These include:

　　Direct listing. In a strategy also known as a direct public offering (DPO), the company simply allows its shares to be traded. It must work with an exchange to make this happen, and the exchanges will require a minimum listing amount. (For the New York Stock Exchange, it’s $100 million, or a minimum of $250 million in newly issued and existing shares.) Some well-known companies, such as crypto platform Coinbase (COIN), music streamer Spotify (SPOT), and software developer Palantir Technologies (PLTR) came to market as DPOs. Merger with a SPAC. A special purpose acquisition company (SPAC) is a public company that’s formed to collect money from investors, then use it to acquire a private company. When the SPAC closes an acquisition, the company is public. Companies that successfully went public via SPACs include sports betting company DraftKings (DKNG), electric vehicle maker Lucid Group (LCID), and financial company SoFi Technologies (SOFI).Reverse merger. A private company can go public through a merger with a penny stock—a low-priced stock that has few real assets and thus could be acquired quickly and perhaps more cheaply compared to the costs of an IPO. Analysts may refer to such deals as reverse mergers or shell transactions.Sale of the company. A private company may decide that it’s easier to merge with—or be acquired by—a public company, with all the effort that combining two businesses entails, rather than go through the IPO process.No matter how a company goes public, it’s responsible for complying with all listing and reporting requirements.

　　The bottom lineGoing public is a long process, but with a potentially big payoff in terms of capital infusion, attention from stock analysts and financial media outlets, and—as the company grows—perhaps inclusion in one or more stock indexes.

　　But as glamorous as a stock exchange listing may be, it comes with compliance and reporting requirements that not all companies are prepared to meet. For those that can do the work, it can turn a business into a household name, and perhaps even a legend.
