Prospectus regime changes in the EU and U.K. – a debt capital markets outlook

There are other changes in application from December 4, 2024 in the areas of use of languages, equivalence and the universal registration document.

Are any of the March 5, 2026 changes relevant to debt securities?

The changes that will apply from March 5, 2026 relate to alleviated prospectus regimes. The PR’s simplified disclosure regime for secondary issuances is replaced by an EU follow-on prospectus concept, available where an issuer has securities already admitted to trading on a regulated market or SME growth market for 18 months. Further details on content of the follow-on prospectus are expected and will require analysis before it is possible to gauge whether this will be more popular than the simplified prospectus it replaces.

What changes come into play further down the track, on June 5, 2026?

These changes are more significant and will require extensive Level 2 work by ESMA and the Commission.

Proposals in respect of some of these changes are covered by ESMA’s consultation published on October 28, 2024 on draft technical advice concerning the Prospectus Regulation (the ESMA Consultation), which includes draft amendments to the existing delegated regulation (EU) 2019/980 on format, content, scrutiny and approval of the prospectus (the PR Delegated Regulation). These include:

• Prospectuses will be required to follow a standardised format and sequence, subject to a derogation for securities offered in a third country where an offering document is prepared under the law, rule or practice of that country. Based on the proposals included in the ESMA Consultation, ESMA seek to adopt a pragmatic approach, which is likely to be welcome as far-reaching changes would prove burdensome for issuers.
• Streamlining changes are also being introduced, such that financial information included in a non-equity prospectus will only be required for the last financial year (and not the last two as under the current regime). Furthermore, some combining of the currently separate retail and wholesale non-equity disclosure annexes into a single framework is being considered. The complete picture on what prospectuses will look like once the new regime is fully in application will not be available for a while as further ESMA and Commission workstreams are anticipated.
• The Amending Regulation gives the Commission the power to introduce a disclosure annex into the PR Delegated Regulation to be followed for debt securities advertised as taking into account environmental, social and governance (ESG) factors or pursuing ESG objectives. The ESMA Consultation includes a draft of this annex, which would operate as a building block to be followed in addition to the non-equity annexes when drawing up a prospectus. It builds on ESMA's public statement on sustainability disclosures from summer 2023. Other changes serve to acknowledge the EU Green Bond Regulation and the European Green Bond (EuGB) label under it, such as those requiring prospectuses to incorporate by reference relevant information from an issuer's factsheet under that regulation. ESMA are clearly thinking about how prospectus disclosure should fit together with EUGB requirements, including in the context of programmes.
• The Amending Regulation will amend the summary requirements for retail prospectuses, including to allow the inclusion of charts, graphs and tables, and to allow a small increase in the page limit if there are guarantors. Also, a statement warning that the issuer has identified environmental issues as a material risk factor will need to be included in the introductory section, if applicable.

The Amending Regulation provides grandfathering for prospectuses approved until June 4, 2026. Our understanding is that this means that programme issuers will not have to comply with the new rules due to apply from June 5, 2026 for the remainder of their validity, e.g. if a base prospectus is approved on June 4, 2026 the issuer will not need to comply with the new rules until June 2027.

U.K. prospectus regime: Potential changes and comparison with EU prospectus regime

The U.K.’s prospectus regime is currently based on the PR, which was retained in U.K. law after Brexit as the U.K. Prospectus Regulation (the U.K. PR). The U.K. has been reviewing its prospectus regime as part of its wider efforts to reform its capital markets and enhance its attractiveness as a listing venue. As part of this, the U.K. PR will be replaced by the Public Offers and Admission to Trading Regulations 2024 (the POATRs), with all detailed requirements relating to admission to trading to be covered in Financial Conduct Authority (FCA) admission rules. The FCA published a consultation paper (FCA CP 24/12) which closed in October 2024, setting out detailed proposals. A second consultation paper (covering retail bonds and related points) is expected in January 2025. Final FCA rules are expected towards the end of the first half of 2025, with application anticipated at the end of 2025 or early in 2026.

In relation to debt securities, the FCA proposes to stick broadly with current U.K. PR requirements, but expected changes include:

• The FCA is planning to streamline disclosure requirements by introducing a single disclosure framework for debt securities as the FCA considers that the current distinction between retail and wholesale disclosure regimes has been one of the factors holding back the development of a retail bond market in the U.K. The expectation is that the FCA will base its single framework on the existing wholesale disclosure requirements with further disclosure alleviations for "seasoned" U.K listed corporates issuing simple, standardised, unsubordinated, unsecured corporate bonds to a wide range of retail and wholesale investors. The FCA is expected to consult on the details of its single framework and these proposed alleviations in its second consultation paper due early next year. At this stage (and as a point of difference from the EU), it seems strict format and sequencing requirements for prospectuses are not planned.
• Unlike the EU, the FCA does not propose to introduce any mandatory sustainability disclosure requirements for prospectuses, other than a requirement that an issuer states whether the bonds have been marketed as green, social or sustainable and/or issued under an ESG framework. Instead, the FCA proposes to introduce voluntary disclosure considerations intended to guide issuers to provide relevant disclosures.
• Similarly to the EU, the FCA proposes to permit future financial information to be incorporated by reference without the need to publish a supplement.
• An area of potential significant divergence is in relation to supplements. The FCA are proposing more flexibility which would allow the use of a supplement to amend conditions in a base prospectus in such a way that amounts to the introduction of new products by way of a supplement. There are likely to be conditions attached to this (e.g., this may not be available for introducing asset-backed securities or securities linked to an underlying asset), but the flexibility being proposed by the FCA will be welcomed by issuers.

Whilst the proposed new rules do not reference the current regime's exemption from withdrawal rights for supplements to a wholesale prospectus prepared only for admission to trading on a regulated market, we anticipate that the current approach will continue to apply under the new regime.

• Like the EU, the FCA are looking at increasing the cap applicable to tap exemptions, although they are proposing a higher percentage limit of 75%. Changes to other exemptions from the requirement for a prospectus are being considered, including deletion of the exemption for non-profit making bodies, and expansion of the list of exempted securities to include instruments of Islamic finance benefitting from the credit support of a sovereign, which would facilitate the issuance of Islamic finance instruments.
• The FCA proposes an alleviated liability regime for protected forward-looking statements (PFLS), intended to encourage issuers to provide more forward-looking information to investors, subject to conditions and safeguards. There are limited circumstances in which the PFLS regime may be used by debt issuers (relevance is expected to be greater in the equity capital markets space). It nonetheless represents a noteworthy difference from the EU regime which does not provide similar protections, although change may be on the horizon. In the EU, the Amending Regulation requires the Commission to look at prospectus liability and ESMA recently published a Call for Evidence in connection with this. Questions in ESMA’s Call for Evidence address different aspects of prospectus liability, including whether safe-harbour provisions for forward looking statements (such as those in the U.S., or those planned for the U.K.) should be introduced at an EU level.
• In a further difference from the EU PR (which applies to regulated market admissions), the FCA proposes requirements for Primary MTFs that do not meet the “qualified investor condition”. For example, an MTF admission prospectus will be required, although the market operator will set the detailed content for this. Primary MTF requirements are not expected to impact London’s International Securities Market (ISM) due to the qualified investor condition.
