The IPO Process: How Companies Go Public
An Initial Public Offering (IPO) is when a private company sells shares to the public for the first time. This guide explains why companies go public, the steps in the IPO process, and the finance team's role.
Going public is one of the biggest milestones in a company's life. An initial public offering (IPO) is the process by which a private company sells shares to the public for the first time and lists on a stock exchange. It can raise substantial capital and transform a company's profile — but it's a complex, demanding journey. This guide explains what an IPO is, why companies do it, the steps in the process, and the trade-offs involved. It draws on related corporate-finance topics like due diligence and valuation.
What is an IPO?
An initial public offering is the first time a private company offers its shares to public investors and becomes listed on a stock exchange. Before an IPO, ownership is held privately — by founders, employees and private investors. After it, the company's shares can be bought and sold by the public, and the company becomes subject to the disclosure, reporting and governance requirements that come with being listed. It's the transition from a private to a public company.
Why do companies go public?
Companies pursue an IPO for several reasons. The headline one is raising capital — selling shares brings in funds to invest in growth, pay down debt or strengthen the balance sheet. An IPO also provides liquidity, giving early investors and employees a way to realise the value of their shares. It can raise the company's profile and credibility with customers, partners and talent, and create a publicly traded "currency" (the shares) that can be used for acquisitions. Set against these, going public brings significant cost, scrutiny and obligation — so it's a major strategic decision, not just a financing one.
The IPO process step by step
- Preparation and decision. The company assesses whether it's ready — in terms of size, financials, governance and growth story — and decides to proceed.
- Appointing advisers. Investment banks (underwriters), lawyers, accountants and other advisers are appointed to manage the process.
- Due diligence and the prospectus. Extensive due diligence is carried out, and a detailed prospectus is prepared, setting out the business, the risks and the financials for prospective investors.
- Regulatory review. The prospectus and listing documents are filed with the relevant regulator and exchange, and reviewed and approved.
- Marketing and the roadshow. Management presents the investment case to institutional investors to build demand and gauge appetite.
- Pricing. Based on investor demand and valuation work, the offer price (and size) is set.
- Listing and trading. The shares are allocated and begin trading on the exchange — the company is now public.
How the offer price is set
Pricing an IPO is part science, part judgement. The advisers value the business using methods like comparable company analysis and discounted cash flow, then gauge real investor demand during the roadshow to set a price (and offer size) that raises the intended funds while leaving enough upside to support a healthy debut. Price it too high and the shares may fall on listing; price it too low and the company leaves money on the table — which is why pricing is one of the most scrutinised parts of the whole process.
Alternatives to a traditional IPO
A traditional IPO isn't the only route to becoming public. A direct listing lets a company list its existing shares on an exchange without raising new capital or using underwriters, which can be cheaper but doesn't bring in fresh funds. A SPAC (special purpose acquisition company) is a listed shell that merges with a private company to take it public. And some companies simply stay private for longer, raising large rounds of private capital instead. Each route has different costs, speed and trade-offs, so the choice depends on the company's goals.
The advantages and the trade-offs
The advantages — access to capital, liquidity, profile and an acquisition currency — are significant. But going public has real downsides too. It's expensive and time-consuming, with substantial advisory fees and management effort. It brings ongoing obligations: regular public reporting, regulatory compliance and far greater scrutiny. It exposes the company to market pressures and short-term expectations, and dilutes the control of existing owners. For some companies the trade-off is clearly worth it; for others, staying private (or raising private capital) is the better path.
