Regulation (EU) No 596/2014, Chapter 3 — Disclosure requirements. 1. Issuers and any person acting on their behalf or on their account, shall each: 1. draw up a list of all persons who have access to inside information and who are working for them under a contract of employment, or otherwise performing tasks through which they have access to inside information, such as advisers, accountants or credit rating agencies (insider list); 2. promptly update the insider list in accordance with paragraph 4; and 3. provide the insider list to the competent authority as soon as possible upon its request. 2. Issuers and any person acting on their behalf or on their account, shall take all reasonable steps to ensure that any person on the insider list acknowledges in writing the legal and regulatory duties entailed and is aware of the sanctions applicable to insider dealing and unlawful disclosure of inside information. Where another person is requested by the issuer to draw up and update the issuer’s insider list, the issuer shall remain fully responsible for complying with this Article. The issuer shall always retain a right of access to the insider list that the other person is drawing up. 3. The insider list shall include at least: 1. the identity of any person having access to inside information; 2. the reason for including that person in the insider list; 3. the date and time at which that person obtained access to inside information; and 4. the date on which the insider list was drawn up. 4. Issuers and any person acting on their behalf or on their account shall each update their insider list promptly, including the date of the update, in the following circumstances:Each update shall specify the date and time when the change triggering the update occurred. 1. where there is a change in the reason for including a person already on the insider list; 2. where there is a new person who has access to inside information and needs, therefore, to be added to the insider list; and 3. where a person ceases to have access to inside information. 5. Issuers and any person acting on their behalf or on their account shall each retain their insider list for a period of at least five years after it is drawn up or updated. 6. Issuers whose financial instruments are admitted to trading on an SME growth market shall be entitled to include in their insider lists only those persons who, due to the nature of their function or position within the issuer, have regular access to inside information. By way of derogation from the first subparagraph of this paragraph, and where justified by specific national market integrity concerns, Member States may require issuers whose financial instruments are admitted to trading on an SME growth market to include in their insider lists all persons referred to in paragraph 1, point (a). The insider lists referred to in the first and second subparagraphs of this paragraph shall be provided to the competent authority as soon as possible upon its request. ESMA shall develop draft implementing technical standards to determine the precise format of the insider lists referred to in the second subparagraph of this paragraph. The format of the insider lists shall be proportionate and represent a lighter administrative burden compared to the format of insider lists referred to in paragraph 9. ESMA shall submit those draft implementing technical standards to the Commission by 1 September 2020. Power is conferred on the Commission to adopt the implementing technical standards referred to in the fourth subparagraph of this paragraph in accordance with Article 15 of Regulation (EU) No 1095/2010. 7. This Article shall apply to issuers who have requested or approved admission of their financial instruments to trading on a regulated market in a Member State or, in the case of an instrument only traded on an MTF or an OTF, have approved trading of their financial instruments on an MTF or an OTF or have requested admission to trading of their financial instruments on an MTF in a Member State. 8.

ESMA shall review the implementing technical standards on the alleviated format of the insider lists for issuers admitted to trading on SME growth markets to extend the use of such a format to all insider lists referred to in paragraph 1 and in paragraph 6, first and second subparagraphs. ESMA shall submit those draft implementing technical standards to the Commission by 5 September 2025.
