Circular No. 381 “Requirement to Report Beneficial Owners”

Dear Participants,

The Central Securities Depository hereby announces that, in accordance with the provisions of Law 19,913 on the Financial Analysis Unit (UAF) and Law 21,453, which introduced amendments to the Tax Code, our depositors are required to report the beneficial owners and/or controllers of their accounts. As established in UAF Circular No. 62, beneficial owners are defined as:

• The natural person(s) who ultimately holds, directly or indirectly, through companies or other mechanisms, a stake equal to or greater than 10% of the capital or voting rights of a specific legal entity or legal structure.
• The natural person(s) who, notwithstanding holding directly or indirectly a stake of less than 10% of the capital or voting rights of a legal entity or legal structure through companies or other mechanisms, exercises effective control over the decision-making of the legal entity or legal structure.

To comply with this requirement, the DCV is making available to the parties the affidavit for the identification of beneficial owners and the customer information update form, which must be submitted during the month of April 2026. Please send these documents to the email address [email protected].

Depositors are reminded of the importance of keeping information regarding beneficial owners, controlling parties, powers of attorney, legal history, and other relevant details up to date.
