An IPO (Initial Public Offering) is when a private company offers its shares to the public for the first time. It allows the company to raise capital and become publicly traded. Investors can then buy and sell its shares on a stock exchange.
What Is an IPO? (Simple Explanation with Examples)
An IPO marks a major transition in a company’s lifecycle: it moves from private ownership to being publicly traded on a stock exchange.
Before going public, a company is typically owned by founders, venture capital firms, and early institutional investors. After an IPO, its shares become available to public investors, and the company is listed on an exchange.
For investors, IPOs can be appealing because they offer exposure to companies at an early stage of their public journey. However, in practice, getting access at the IPO price is often difficult—retail investors are usually not first in line.
Companies typically go public to:
- Raise capital for expansion and growth
- Fund new projects or acquisitions
- Provide liquidity for early investors and founders
An IPO can include:
- Newly issued shares (raising fresh capital for the company)
- Existing shares sold by current shareholders
How Do IPOs Work? (Step-by-Step Process)
Here’s how the process usually unfolds:
Preparation
The company works with investment banks (known as underwriters) to prepare financial statements, valuations, and disclosures.
Regulatory approval
In Europe, detailed documents must be submitted to regulators for approval before the offering can proceed.
Book-building and pricing
A price range is set based on investor demand. Through the book-building process, institutional investors indicate how many shares they’re willing to buy and at what price.
Share allocation
Shares are allocated—primarily to institutional investors, with limited portions sometimes available to retail investors.
Listing on the exchange
The company’s shares begin trading on a public exchange, such as Euronext.
Post-IPO trading
Once trading starts, the share price is driven by supply and demand—often leading to significant price movements in the early days.
Lock-up period
Early investors (such as founders or venture capital firms) are typically restricted from selling their shares for a set period after the IPO. This helps prevent immediate large sell-offs.
IPO Example (European Company)
Imagine a European tech company listing on Euronext:
- IPO price: €20
- Investors subscribe to shares before listing
- On the first day of trading, the stock opens at €25
This kind of jump often reflects strong demand—but it can just as easily go the other way. Some IPOs open below their offer price if sentiment is weaker than expected.
After the IPO, the company must comply with ongoing reporting and disclosure requirements, making it more transparent than it was as a private business.
Pros and Cons of IPO Investing
Pros
- Access to newly listed companies
- Potential for strong early price movements
- Opportunity to invest in growing businesses
- Greater transparency after listing
- Liquidity for early shareholders
Cons
- High volatility, especially shortly after listing
- Limited access for retail investors
- Uncertainty around pricing
- Limited public track record
- Risk of overvaluation driven by hype
A common misconception is that IPOs are “easy wins.” In reality, many underperform after the initial excitement fades.
Are IPOs a Good Investment?
IPOs tend to attract investors looking for growth—but they’re not suitable for everyone.
They are more commonly considered by investors who:
- Understand higher-risk investments
- Are comfortable with short-term volatility
- Want exposure to newly listed companies
For most long-term investors, IPOs are better treated as a small part of a broader portfolio rather than a core strategy.
IPO Regulation and Access in Europe
How Are IPOs Regulated in Europe?
In Europe, IPOs are governed by the EU Prospectus Regulation.
Companies must publish a detailed prospectus that includes:
- Financial information
- Business model and strategy
- Key risks
This document must be approved by regulators before shares can be offered to the public.
Where Do IPOs Take Place? (Stock Exchanges)
Companies going public in Europe may list on exchanges such as:
- Euronext
- Deutsche Börse (including Xetra)
- Other regional European exchanges
The choice of exchange can influence visibility, liquidity, and investor base.
Can Retail Investors Buy IPO Shares?
Access to IPOs for retail investors is often limited.
In most cases:
- Institutional investors receive the majority of allocations
- Retail access depends on the broker, country, and structure of the offering
Some modern platforms are improving access, but availability is still uneven across Europe.
IPO vs Direct Listing vs SPAC
Not all companies go public through traditional IPOs. Alternatives include:
- Direct listings – Shares begin trading without a new capital raise
- SPAC mergers – Companies merge with a publicly listed shell company
These routes differ in structure, transparency, and risk profile.
Key IPO Terms to Know
- Stock – Shares issued during an IPO
- Stock Exchange – Where shares begin trading
- Market Capitalization – Often established based on IPO pricing
- Broker – Used to participate in IPOs or trade shares afterward
- Secondary Market – Where shares trade after the IPO
