RE: “Protegiendo al Consumidor (P.A.C.) c/ BBVA Banco Frances S.A. s/ Repetición de Sumas de Dinero" (File 27.694 /2025), pending before Civil and Commercial Court No. 14, Exclusive Office, of Mar del Plata.

Dear Sirs:

I hereby address you, in my capacity as Head of Market Relations of Banco BBVA Argentina S.A., in order to inform that Banco BBVA Argentina S.A. (hereinafter “BBVA”) has been notified of a class action filed by the Protegiendo al Consumidor (P.A.C.).

The Association seeks the unconstitutionality of Section 20 of Decree 70/2023, which modified Section 18 of Law 25.065 - whereby the limit on punitive interest was eliminated - and the limit of such interest was reestablished as provided by the previous Section 18, in force until December 20, 2023, and consequently, the reimbursement of the amounts collected in excess from users and consumers of credit cards issued by the Bank in the Province of Buenos Aires, plus interest and costs.

It is important to remark that this action is informed even though it is materially impossible to determine to date, whether the claim has a significant economic importance, since such claim is brought for an indeterminate amount, materially impossible to be determined with certainty today.

The Bank is analyzing the content of the lawsuit and defining the course of action, thus considering that even in the hypothetical case of an adverse decision regarding this dispute, such circumstance will not have a significant impact on its assets and activities.

Yours faithfully,

BANCO BBVA ARGENTINA S.A.
