Stock exchange listing (IPO, direct listing or SPAC)
Become a public company by listing your shares on a national securities exchange such as the New York Stock Exchange or Nasdaq, through an initial public offering, a direct listing or a merger with a SPAC. Access to large amounts of capital, with ongoing public reporting, costs and scrutiny.

How it works
There are three main ways to become a listed public company, as the SEC describes them:
- Initial public offering (IPO): the company sells newly issued shares to investment banks (underwriters), which sell them on, mainly to institutional investors. The traditional route, with an underwriter's help in marketing the shares and managing early trading, but with high transaction costs, including underwriter fees, and a long process.
- Direct listing: existing shareholders sell their shares directly to the public, typically without the company raising new money. Potentially lower costs, but no underwriter and no control over the first investors, so it has suited a few very large, well-known companies.
- Merger with a special purpose acquisition company (SPAC): a shell company that has already raised money in its own IPO merges with your company, usually within two years of that IPO. More certainty over the amount raised and possibly a shorter timetable, but high transaction costs and dilution from the SPAC's sponsors and other investors.
Registration: an IPO needs a registration statement filed with the SEC, describing the business, the securities offered and management, with financial statements audited by an independent public accountant. To list, the company must also meet the exchange's financial and other listing standards, and keep meeting them to stay listed.
After listing: public companies file annual, quarterly and current reports with the SEC, and major shareholders, officers and directors report their holdings and trades. The company and its leaders can be liable if these duties are not met.
Emerging growth companies: a company with total annual gross revenues of less than $1.235 billion in its last fiscal year can use scaled rules for up to five years after its IPO, including two years of audited financial statements instead of three, no auditor attestation of internal controls under Sarbanes-Oxley section 404(b), and "test-the-waters" talks with institutional investors before filing.
Upsides and downsides
Upsides
- Access to large amounts of capital, now and later
- Shares that existing investors and staff can sell more easily
- A higher profile, and shares that can be used to reward staff
Downsides
- High transaction costs and a long, demanding process
- Ongoing reporting, governance rules and public scrutiny
- Founders may lose control as ownership spreads
Risks
- Market conditions can close the window for an IPO at short notice
- Liability for misleading disclosure falls on the company and its leaders
- Failing to meet continued listing standards can lead to delisting
What it costs
- How it is priced
- New shares sold to the public, with underwriting fees, legal, audit and listing costs, plus ongoing reporting costs
- Costs that are easy to miss
- Underwriter fees and other transaction costs, which the SEC calls high
- Ongoing costs of SEC reporting, audits, internal controls and exchange fees
- Management time spent on investors, analysts and disclosure
Usually large. A direct listing typically raises no new money for the company.
