Ref.: Material Event

Dear Sirs,

We are writing to you in order to inform that our main subsidiary, Banco de Galicia y Buenos Aires S.A.U. (“the Bank”), has been notified of a class action lawsuit captioned “Usuarios y Consumidores Unidos v. Banco Galicia y Buenos Aires S.A. s/ Ordinary Proceeding, Case No. 26152/2024.

The plaintiff challenges the manner in which Banco Galicia applies the Tax for an “Inclusive and Supportive Argentina” (Impuesto PAIS), established by Law No. 27,541 (Sections 37 et seq.), as well as the withholding applied on account of income tax and personal assets tax.

The lawsuit was filed before National Court of First Instance in Commercial Matters No. 7, Clerk’s Office No. 14.

The Bank is analyzing the content and implications of said lawsuit. It is estimated that in case of an unfavorable resolution of this dispute, it will not have a significant impact on Banco Galicia’s shareholders’ equity.

Yours faithfully,

A. Enrique Pedemonte

Attorney in fact

Grupo Financiero Galicia S.A.
