Messrs:

Security and Exchange Commission

RE: “Argentine Consumer Defense Association("ADUC") vs. Banco BBVA Argentina S.A on Matter to be classified " (File 19318-2023), pending before the Court of FirstInstance on Civil and Commercial Matters Nº 9, Mar del Plata, Province of Bs. As.

With due consideration:

I hereby address you in my capacity as Head of Market Relations of Banco BBVA Argentina S.A., in order to inform that our entity has been notified of a class action brought by the Argentine Consumer Defense Association ("ADUC")

The Association challenges the collection of the stop-payment fee on checks issued by consumers, and requests not to pay and refund the money received as fee for the stop-payment to each of the affected clients plus interest and punitive damage

It is important to remark that this action is reported, without prejudice to the fact that it may not be determined to date whether it is of significant economic importance, as this claim is filed for an undetermined amount materially impossible to determine with certainty to date.

The Bank is analyzing the content and implications of the claim, considering to date that in the eventual and hypothetical case of an unfavorable resolution of this dispute, this shall not have a significant impact on its assets and business.

Yours faithfully,

BANCO BBVA ARGENTINA S.A.

Eduardo González Correas

Head of Market Relations of Banco BBVA Argentina S.A.
