What an IPO actually is
An initial public offering is the first time a company sells shares to the public and has them admitted to trading on a stock exchange. Two things happen at once, and it helps to keep them apart:
- The offering. New shares (primary) and/or existing shares (secondary) are sold to investors at a set price. Primary shares raise money for the company. Secondary shares turn existing owners' stakes into cash.
- The listing. The shares are admitted to a trading venue, which brings permanent obligations: regular financial reporting, disclosure of price-sensitive information, governance standards and scrutiny by investors, analysts and the press.
The offering lasts a few weeks. The listing lasts as long as the company stays public. Most of what makes an IPO hard, and most of what makes it valuable, sits on the listing side.
Good reasons to go public
Growth capital at scale. A listing gives access to a deep pool of investors who can fund a growth plan that exceeds what banks, the current owners or private funds are willing to provide. It also opens the door to follow-on offerings later.
A liquid currency. Listed shares can be sold by founders, early investors and employees over time. They can also be used to pay for acquisitions or to fund employee share plans that people actually value.
An independent valuation. The market sets a daily price for the business. That transparency helps with financing, with partners and with succession planning in family-owned companies.
Profile and credibility. Public companies get press coverage, analyst research and a certain standing with customers, suppliers and lenders. Larger counterparties often find it easier to sign long contracts with a listed supplier whose numbers are public.
Discipline. Many CFOs see the forced upgrade of reporting, controls and governance as a benefit in itself: the company becomes more professional, faster.
Weak reasons to go public
- "Our competitor listed." Market timing and peer pressure do not replace a story investors want to buy.
- "We need cash quickly." An IPO takes many months of preparation and can be postponed by market conditions at the last minute.
- "Exit for all owners at once." Investors are wary of offerings where insiders sell most of their stake; secondary sales are usually limited and followed by lock-ups.
- "We want a higher valuation than private buyers offer." Public market valuations move with the market and with sentiment towards the sector. They can be higher or lower than private bids.
What it costs
Costs come in two forms.
One-off costs include underwriting fees, legal counsel for the company and the banks, auditors (including comfort letters and any restatements), exchange and regulator fees, printing and data rooms, financial PR and roadshow expenses. Internal costs are easy to underestimate: the finance team, legal team and management will spend a large share of their time on the project for months.
Recurring costs include the audit and reporting cycle, investor relations, board and committee fees, directors' and officers' insurance, listing fees, compliance (insider lists, disclosure processes, managers' transactions) and the time management spends with investors.
Use the IPO cost budget tool to structure both, using your own quotes.
What changes for management
- Transparency. Results, strategy, risks, executive pay and related-party dealings become public.
- Rhythm. Reporting dates become fixed and visible. Missing guidance or delaying a report has consequences.
- Disclosure duty. Price-sensitive information has to be published promptly. That changes how deals, setbacks and management changes are handled internally.
- Control. Founders and families often keep control through retained stakes or share structures, but they now share the company with investors who vote and comment.
- Market noise. The share price will move for reasons unrelated to the business. Management needs the temperament for that.
The alternatives
| Route | What it is | When it fits | Watch out for |
|---|---|---|---|
| Traditional IPO | Underwritten offering with bookbuilding and a new listing | Companies raising meaningful primary capital that benefit from bank distribution and research | Cost, time, market windows, pricing discount |
| Direct listing | Shares admitted to trading without an underwritten offering; price set by the opening auction | Well-known companies with a broad shareholder base that do not need to raise capital | No price support or stabilisation; venue rules differ on whether new capital can be raised |
| SPAC merger | A listed shell company merges with the target, which becomes public | Companies wanting a negotiated valuation and faster timetable | Sponsor economics, redemptions, dilution, regulatory scrutiny of projections |
| Dual-track | Prepare an IPO and a sale process in parallel | Companies with strategic or private equity buyer interest | Double workload and cost; must keep both credible |
| Private capital | Private equity, growth funds, family offices, strategic investors | Companies not yet IPO-ready, or owners who prefer privacy | Governance rights for investors, exit expectations |
| Listing on an SME segment | Admission to a lighter-regulated growth market | Smaller companies building a capital-markets track record | Lower liquidity and investor attention |
Many companies that end up listing first seriously considered at least one alternative. That analysis is also useful later: it becomes part of the equity story ("why we chose to be public").
A first decision test
Before spending money on advisers, the board should be able to answer yes to most of these:
- Is there a growth plan that needs equity capital, or shareholders who need liquidity, and can that be explained in two minutes?
- Has the company shown a track record investors can analyse: several years of audited figures and a credible plan?
- Can the finance function close the books quickly and reliably, today, and produce figures that would survive an audit and a due diligence?
- Is management ready to spend time with investors and to work under permanent disclosure rules?
- Are the owners aligned on how much they sell, how much control they keep and how long they hold after listing?
- Is the business resilient enough that a delayed or repriced IPO would not hurt it?
The IPO readiness assessment turns this into a scored check across eight areas.
