The Commission Implementing Regulation (EU) 2026/1291 (the “Implementing Regulation“) entered into force on 5 July 2026, introducing a revised set of implementing technical standards on insider list formats and repealing Implementing Regulation (EU) 2022/1210.
The amendments, introduced as part of the Listing Act’s objective of reducing administrative burdens, remove a number of personal data fields and extend the alleviated insider list format (previously available only to SME growth market issuers) to all issuers required to maintain insider lists under the Market Abuse Regulation (“MAR“).
Background
An insider list is a record that issuers and any legal person acting on their behalf or on their account are required to draw up and maintain of all individuals who have access to inside information, whether under a contract of employment or through otherwise performing tasks that give rise to such access, such as advisers, accountants, or credit rating agencies.
