What is an IPO?
IPO stands for initial public offering: the first time a company offers shares to the general public and obtains a listing on an exchange such as Euronext. From that moment anyone with a brokerage account can become a part-owner, and the company must meet disclosure duties that private companies escape. This is information, not investment advice.
Why companies go public
The headline reason is capital: newly issued shares bring money into the business for growth, acquisitions or debt repayment. That is a primary offering.
There is often a second motive: existing shareholders such as founders, venture funds or private equity want an exit. When they sell, the proceeds go to them, not to the company. That is a secondary offering, and the prospectus says which is which.
- Primary offering: new money for the company
- Secondary offering: cash-out for existing owners
- A listing brings continuous reporting obligations
The process step by step
An IPO typically takes six to eighteen months, guided by investment banks acting as underwriters who set the price range, approach institutions and often guarantee placement.

How the price is set
During bookbuilding the company publishes a range, say 18 to 22 euro, and large investors indicate size and price. The final offer price comes out of that book.
It is a negotiated outcome, not an objective valuation. A first-day pop mostly means the offer price sat below market demand, not that the business is performing well.
What the prospectus tells you
The prospectus is the only legally binding, regulator-approved document. Read the risk factors, the use of proceeds, the capital structure and the voting rights before anything else.
The chapters that matter
| Section | What you learn |
|---|---|
| Risk factors | The most honest summary of what can go wrong |
| Use of proceeds | New capital for the company or cash-out for owners |
| Financial history | Growth, margin and whether profit ever existed |
| Capital structure | Debt and dilution from option plans |
| Voting rights | Whether founders keep control via dual-class shares |
| Lock-up | How long insiders cannot sell |
Lock-up, greenshoe and stabilisation
A lock-up of 90 to 180 days stops insiders from selling immediately. Its expiry is a well-known moment of supply pressure.
The greenshoe lets underwriters place up to roughly 15% extra shares and buy back stock to support the price in the first weeks, which means early pricing is not entirely free.
Can retail investors subscribe?
Sometimes. Many European IPOs allocate almost everything to institutions, with a retail tranche only for consumer brands. When demand is strong you are scaled back; when you receive your full request, that itself is a signal.
Waiting and buying after listing is a legitimate alternative: you pay a market-set price and can wait for the first results as a listed company.
What research says about IPO returns
Two patterns recur across decades of studies: positive average first-day returns (underpricing), and underperformance versus comparable listed peers over three to five years.
Companies choose their own timing, usually when sentiment in their sector is high. The seller knows more than the buyer.

Vanliga frågor
Is subscribing to an IPO easy money?
Rarely in a reliable way. Attractive deals scale you back heavily, weak deals fill you completely, and IPOs underperform peers on average over three to five years.
IPO versus direct listing?
An IPO offers shares and usually raises capital. A direct listing merely admits existing shares to trading, without underwriters or new money.
Why do shares often fall around lock-up expiry?
Insiders can sell for the first time, so supply increases abruptly even without company news.
Is an IPO the same as a crypto token sale?
No. An IPO is a regulated share offering with an approved prospectus and shareholder rights; token sales usually convey neither ownership nor votes.
