You could lose all the money you invest in private markets
Private market investments are highly illiquid – there is no guarantee of liquidity, and you may not be able to sell your shares or realise your investment for several years or at all
These investments are high risk and not suitable for most investors
You should only invest if you can afford to lose all your investment
Private market investments should only form a small part (typically no more than 10%) of your investment portfolio
What is an IPO?
Introduction
An Initial Public Offering (IPO) is the process by which a private company offers shares to the public for the first time. This allows the company to raise capital from public investors and become a publicly traded company.

Why Companies Go Public
Companies pursue IPOs for several key reasons:
- Raise Capital: Access to public markets provides funding for expansion, research, or debt repayment.
- Liquidity: Existing shareholders (founders, employees, early investors) can sell their shares.
- Profile: Public listing increases company visibility, credibility, and brand recognition.
- Currency for Acquisitions: Public shares can be used as currency for mergers and acquisitions.

The IPO Process
- 1. Preparation: Company selects underwriters (investment banks) and prepares financial documentation.
- 2. Due Diligence: Underwriters conduct thorough review of the company’s financials and operations.
- 3. Filing: Company files registration documents with regulators (e.g. prospectus with FCA in UK).
- 4. Marketing: Roadshow presentations to potential institutional investors.
- 5. Pricing: Final offer price determined based on demand.
- 6. Allocation: Shares allocated to investors who placed orders.
- 7. Admission: Shares begin trading on stock exchange.
Retail Participation
Historically, IPOs were primarily available to institutional investors. Recent regulatory changes in the UK have made it easier for retail investors to participate in IPOs through platforms like RetailBook.
Retail investors can now access the same pricing and opportunities as institutional investors, democratising access to primary markets.

Key Considerations
Before Investing in an IPO:
- Read the prospectus carefully
- Understand the company’s business model and financials
- Review risk factors thoroughly
- Consider your investment objectives and risk tolerance
- Be aware that newly listed shares may be volatile
- Understand the allocation method and lock-up periods
Risk Factors
IPO investments carry specific risks:
- Limited History: Less public financial data available compared to established listed companies.
- Volatility: Share prices can be highly volatile in the initial trading period.
- Allocation Risk: You may not receive all shares requested, or any at all.
- Lock-up Expiry: Share prices may drop when insider lock-up periods end, increasing supply.
