UK equity capital markets – the FCA's new prospectus rules for admissions to UK public markets

Key takeaways 

  • The UK Financial Conduct Authority (FCA) has published its new prospectus rules for admissions to trading on UK public markets.
  • In general, the FCA has adopted the rules proposed in its 2024 consultation paper, with some changes in the detail. The FCA anticipates that its new rules will come into effect on 19 January 2026.
  • The UK’s new regime for public offers and admissions to trading is based on the Public Offers and Admissions to Trading Regulations 2024 (POATRs), which will replace the current regime derived from the EU Prospectus Regulation.
  • The FCA’s new rules will be an important part of the new UK regime once the POATRs come fully into force, and will sit alongside the FCA’s reformed UK Listing Rules, which came into force at the end of July 2024.
  • This article highlights key aspects of the FCA’s proposed prospectus rules for the admission of equity shares to trading on UK public markets.

Background

  • Once in force, the POATRs will create a new framework consisting of a general prohibition on offering transferable securities to the public in the UK, subject to specific exemptions.
  • The scope of the new regime will also extend to certain non-transferable debt securities such as mini-bonds.
  • Key exemptions that are currently available will continue to apply, such as offers to qualified investors (e.g., institutional investors) and fewer than 150 other persons, and offers to directors and employees, among others.
  • There will also be new exemptions, including for offers of unquoted equity securities to existing shareholders and offers of unquoted securities made on an FCA-regulated ‘public offer platform’ (an electronic platform whose operator is authorised by the FCA to carry on this new regulated activity). Alongside its new prospectus rules, the FCA has issued the final form of its rules for firms authorised to operate these platforms.
  • A further exemption covers offers of securities admitted or to be admitted to trading on a UK regulated market, such as the London Stock Exchange’s main market, or a primary multilateral trading facility (MTF), such as AIM or the AQSE Growth Market. This is because the POATRs empower the FCA to set the prospectus and related rules for admission to these markets (although for certain matters these powers operate indirectly by enabling the FCA to require MTFs to have in place relevant rules).
  • Offers of securities to raise £5 million or less (in any period of 12 months) will also be exempt. Offers to raise larger amounts would need to fall within another exemption or be made on an FCA-regulated public offer platform.
  • Offers that would otherwise be exempt will still need to comply with an equality of information requirement unless they are below a £1 million threshold. This requires the offeror to ensure all material information disclosed to one investor is disclosed to all other investors.

FCA rules on admission to UK regulated markets and UK primary MTFs

  • Broadly, the FCA has adopted the rules proposed in its consultation, with some changes in the specifics. The new rules will therefore require a prospectus to be published when a company seeks admission of its shares for the first time to trading on a UK regulated market, such as the London Stock Exchange’s main market, or a UK primary MTF that retail investors can access, such as AIM or the AQSE Growth Market (other than for certain simplified routes to admission).
    • The content requirements for a prospectus for admission to a UK regulated market (which, as now, would require FCA approval), will be largely the same as the current requirements based on the EU-derived Prospectus Regulation and related regulations. As a result, prospectus documents, together with the associated rights and obligations, will remain largely unaltered. However, as outlined in the consultation paper, there will be some important changes, most notably in relation to clearly demarcated ‘protected forward-looking statements’ (PFLSs) (where liability will be based on a fraud standard, rather than a negligence standard, provided the statement is within the scope of the FCA’s three-part approach, as originally proposed in its consultation). The prospectus summary will also see an increase to a maximum of 10 pages and other minor changes. The FCA plans to consult later in 2025 on additional guidance for PFLSs, working capital statements (which will still be required), complex financial histories and the new content requirements for climate-related disclosures. As proposed in the consultation, to encourage companies to include retail investors in fundraisings, an IPO prospectus will only need to be available for three working days before the offer ends, rather than the current six.
    • Under the POATRs, an MTF admission prospectus will be subject to the same statutory responsibility and compensation provisions as apply to a prospectus for admission to a UK regulated market. However, primary MTFs such as AIM and the AQSE Growth Market will be able to set their own content and approval requirements for an MTF admission prospectus within the framework of the POATRs and the FCA’s rules. In particular, the FCA’s rules address the responsibility attaching to producing an MTF admission prospectus, supplementary MTF admission prospectuses, withdrawal rights, PFLSs and advertisements. As it originally proposed, the FCA has decided to base these broadly on the equivalent rules for admissions to UK regulated markets, with adjustments to reflect the remit of primary MTFs to determine the content of MTF admission prospectuses. Alongside these changes, the London Stock Exchange is considering some potentially deregulatory changes to the AIM rules designed to enhance the attractiveness of AIM as a market.
  • In relation to further issues of shares already admitted to trading:
    • The most significant change will be for secondary issues of shares already admitted to trading on a UK regulated market. Despite receiving mixed feedback to this proposal, the FCA intends to proceed as planned with only requiring a company to publish a prospectus for further issues of these shares if (over a 12-month period) they are equal to 75% or more of shares already admitted to trading. This is a significant increase from the current threshold of 20% and, as the FCA acknowledges, sets the UK regime apart from the EU-equivalent rules (where the EU has opted to make different changes, requiring publication of a further prospectus at the 30% threshold for the first 18 months after IPO and a summary document with a maximum length of 11 pages after that). However, the FCA will still be able to approve a prospectus to be published on a voluntary basis below the 75% threshold (which could be a simplified or full prospectus) if, for example, one is required for an international offering. For further issues by closed-ended funds, a higher threshold of 100% will apply. An issue of qualifying C Shares below this threshold will also not require a new prospectus. Following feedback, the FCA has opted not to impose different disclosure rules where a company in financial difficulties is proposing a rescue financing.
    • The FCA’s framework rules will not require a company with shares admitted to AIM or another primary MTF to publish a prospectus for a further issue of these shares (other than for certain types of reverse takeover), or, in a departure from its rules for UK regulated markets, for the issue of a new class of shares. However, the relevant MTF will be able to make its own rules on secondary offerings, if it wishes to do so.

Where a prospectus is not required for a follow-on offering, the FCA has opted not to require publication of a shorter disclosure document. However, companies will still need to be mindful of their obligations under the Market Abuse Regulation and the FCA’s Disclosure Guidance and Transparency Rules (as well as financial promotion rules), and to ensure they do not publish information that is inaccurate or misleading, or that omits important information.

  • In relation to takeovers where the consideration includes equity securities that are to be admitted to trading, as originally proposed, the FCA will retain the current concept of ‘exemption documents’, but plans to consult further in 2025 on guidance for their content.
  • Alongside these reforms, the FCA is making some changes to its rules designed to streamline the listing process. This includes removing the need to apply to the FCA to admit to listing a follow-on issue of the same class of shares, which will instead occur automatically. Companies will still need to obtain admission of the shares to trading on the market (within 60 days of allotment, or for overseas companies with a secondary listing, within 365 days of allotment), and to notify the admission to trading (within the subsequent 60 days).

Next steps

  • The FCA plans further work to amend the prospectus-related guidance in its Knowledge Base during the remainder of 2025 and anticipates its new rules will come into force on 19 January 2026, alongside the broader POATRs framework.
