What IPO and pre-IPO mean for an investor

In an IPO a company offers its shares to the public for the first time and lists them on an exchange. The offering may consist of new shares, which bring money into the company, existing shares sold by current owners, or both. After listing, the shares trade freely and their price is set by the market rather than by the offering terms.

Pre-IPO usually means a private investment in a company before it lists: a late private round, a convertible instrument or a stake bought from existing shareholders. The investor buys an unlisted security, often at a valuation discount, but without the disclosure, liquidity and investor protection that come with a listing. Whether an IPO follows, and when, is not certain.

How subscription works: the Gulf example

Gulf IPOs are usually split into tranches. The institutional tranche is offered to professional investors, including local and international funds, through bookbuilding: banks collect orders at different prices within a published range and the final price is set at the end of the period. Cornerstone or anchor investors may commit in advance. The retail tranche is offered to individuals, who subscribe at the final price through receiving banks or the exchange's channels.

  • To subscribe on DFM or ADX, an individual normally needs an investor number with the exchange and a bank account for the subscription amount and any refund.
  • Retail investors pay the full subscription amount upfront; if the tranche is oversubscribed, allocation is reduced and the excess is refunded after allocation.
  • The split between tranches, the minimum subscription and the allocation method are set out in the prospectus of each offering and can be changed within the limits stated there.
  • In Hong Kong, rules in force since 4 August 2025 require at least 40% of the offering to go to the bookbuilding tranche, according to the HKEX profile on this site.

Main types of risk

RiskWhat it meansWhere to look
Price riskThe share price after listing can fall below the offering price, including on the first day.Offering terms, valuation section, market conditions
Liquidity riskTrading may be thin, especially for small issuers, so selling quickly at a fair price can be hard.Free float, number of shareholders, market maker arrangements
Business riskRevenue, margins or growth may not meet the expectations behind the price.Risk factors, business description, financial statements
Concentration and controlA controlling shareholder may take decisions that minority holders cannot block.Major shareholders, related party transactions, governance
Supply after lock-upWhen the lock-up ends, large holders may sell, adding supply to the market.Lock-up section, shareholder structure
Currency and jurisdictionReturns depend on the exchange rate, and investor rights depend on the issuer's law and courts.Incorporation, governing law, taxation
Allocation riskIn an oversubscribed retail tranche the investor may receive far fewer shares than requested.Allocation policy in the prospectus
General categories for reference. Each prospectus lists the risks specific to that issuer.

Lock-up and what it means for the price

A lock-up is an undertaking by existing shareholders, and sometimes the company, not to sell or issue shares for a period after listing. It is meant to show that the owners stay committed and to prevent a sudden wave of selling. Some lock-ups are set by exchange rules, others only by agreement with the banks.

  • Saudi Exchange Main Market: 6 months for substantial shareholders; Nomu: 12 months.
  • Nasdaq Dubai Growth Market: 12 months for all pre-listing shareholders.
  • DFM: no mandatory lock-up in the listing rules, so terms depend on the offering.
  • US markets: 180 days is common market practice, not a rule.

The expiry date is public and markets watch it. If a large part of the capital becomes free to trade on one day, the price may come under pressure even without news about the business. The prospectus states who is locked in, for how long and what exceptions apply.

How to read a prospectus

  1. Summary: the offer structure, price range, tranches and timetable in a few pages.
  2. Risk factors: read in full; issuer-specific risks matter more than general market warnings.
  3. Use of proceeds: how much goes to the company and how much to selling shareholders.
  4. Business and industry: what the company does, its market position and dependencies on key customers or licences.
  5. Financial information and management's discussion: audited accounts, trends in revenue, margins, debt and cash flow.
  6. Dividend policy: the stated intention and the conditions attached to it.
  7. Shareholders, management and related parties: who controls the company and on what terms it deals with them.
  8. Terms of the offering: allocation, lock-up, stabilisation, fees and the documents incorporated by reference.

Participating through a licensed intermediary

Access to an IPO normally runs through a bank or broker licensed in the relevant jurisdiction. Before opening an account it is reasonable to confirm the licence in the public register of the regulator, such as the CMA in the onshore UAE, the DFSA in the DIFC or the FSRA in the ADGM, and to understand the fees, the custody arrangements and how refunds are processed. A licensed intermediary will also carry out identity and suitability checks.

Why pre-IPO is risky for a private investor

  • Liquidity: there is no exchange, so the investor may be unable to sell for years, and the IPO may not happen at all.
  • Information: private companies are not bound by public disclosure rules; the investor relies on what the company chooses to share.
  • Valuation and dilution: the entry price is negotiated, and later rounds or the IPO structure can dilute early holders.
  • Legal restrictions: in the UAE, promotion of unlisted products requires a CMA licence and product registration; in the DIFC and ADGM financial promotion is limited to authorised firms or exempt cases.
  • Investor status: in Russia, public offering of certain foreign instruments to non-qualified investors is restricted under Article 51.1 of Federal Law No. 39-FZ, so qualified investor status is a separate topic to check; Saudi Nomu is also limited to qualified investors.
  • Fraud risk: unsolicited offers of 'pre-IPO shares' from unlicensed sellers are a common pattern of investment fraud.
