RE: “Asociación Civil por
los Consumidores y el Medio Ambiente (ACYMA) vs. Banco BBVA Argentina S.A.- Ordinary proceeding " (File 15.087/2024), pending before
the First Instance Court on Commercial Matters Nro 27 Secretariat Nro. 53 Ciudad Autónoma de Buenos Aires.”
With due consideration:
We hereby address you in order to inform that
Banco BBVA Argentina S.A. (hereinafter “BBVA”) has been notified of a class action filed by ACYMA – Asociación
Civil por los Consumidores y el Medio Ambiente.
The purpose of the complaint is to defend consumers
and users - physical persons - who have made purchases in a foreign currency other than the US dollar, abroad and or in the country paying
with credit cards issued by the Bank and whose amount was converted into dollars at the time of its settlement. Such transaction was carried
out without reporting the exchange rate used for said conversion and with an assumed overcharge or commission.
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.
Eduardo González Correas
Head of Market Relations.
