The Swedish Financial Supervisory Authority has proposed new rules from 10 July 2026 for parties submitting major holdings notifications, applying for prospectus approval, and providing ongoing market information through its reporting portal. The changes would add new mandatory fields to the portal forms, require a Legal Entity Identifier for both the notifying party and the issuer, and remove the option to submit major holdings notifications on paper so that all such filings are made digitally through the portal. Issuers would also have to provide their sector and size. In major holdings notifications, the number of shares and voting rights before the transaction would become mandatory rather than optional. Prospectus approval applications would additionally need to state whether the prospectus contains personal data or historical information from before 2026, and include the information referred to in Article 21a of the Prospectus Regulation, including certain exemption documents. The proposal is linked to new European Union rules establishing the ESAP Regulation.
