The newly updated EU rules simplify listings, expand green bond disclosures and modernise how financial information is shared across the Union
April 14th, 2026 – The European Commission has adopted a Delegated Regulation (EU) 2026/858 amending the technical standards governing prospectuses, with the aim of aligning disclosure and classification requirements with recent changes introduced under the EU Listing Act. The measure updates Delegated Regulation (EU) 2019/979, focusing on the data that competent authorities must submit to the European Securities and Markets Authority (ESMA) and expanding the scope of information that issuers may incorporate by reference into prospectuses.
A central element of the regulation is the revision of the metadata used to classify prospectuses. This update reflects the introduction of new prospectus types, such as the EU Growth issuance prospectus and the EU Follow-on prospectus, designed to simplify access to capital markets, particularly for SMEs. The revised framework also incorporates identifiers for financial instruments linked to sustainable finance, including European Green Bonds and sustainability-linked bonds, thereby improving transparency and enabling more detailed supervisory and statistical analysis.
The act further strengthens the integration of EU financial data systems by facilitating the transmission of prospectus-related information to the European Single Access Point (ESAP). By requiring standardised, machine-readable metadata, submitted through existing notification and storage mechanisms, the regulation hopes to streamline reporting processes for national authorities while improving accessibility of financial information at EU level.
In addition, the regulation expands the list of documents that may be incorporated by reference into a prospectus. This includes documents previously approved under the former Prospectus Directive, as well as pre-issuance disclosures for environmentally sustainable and sustainability-linked bonds. These changes are intended to reduce administrative burdens on issuers, increase flexibility in disclosure practices and support the broader development of sustainable finance markets within the Union.
Overall, the delegated regulation forms part of a wider effort to modernise EU capital markets legislation, improve data usability and reduce compliance costs. By aligning prospectus rules with the evolving regulatory landscape,particularly in relation to SME financing and sustainable investment, it seeks to enhance both market efficiency and the availability of high-quality information for investors and supervisors.
