Exhibit 99.1
Buenos Aires
May 23, 2018
To: Comisión Nacional de Valores (Argentine National Securities Commission)
Re: Material Event
To whom it may concern,
We are writing to inform you that our main subsidiary, Banco de Galicia y Buenos Aires S.A. (“Banco Galicia”), has informed us that, as of today, ADUC (Asociación por la Defensa de Usuarios y Consumidores), a local consumer defense organization, has filed class action lawsuit number 8412/35.476/15 against it.
The lawsuit contests as illegitimate the amounts charged by Banco Galicia and the otherco-defendants—Prisma Medios de Pago S.A., American Express Argentina S.A. and First Data Cono Sur S.R.L. (MasterCard)—in relation to “collective life insurance on debit balance” for various credit products.
The plaintiffs seek cessation of the allegedly unlawful conduct and the return of the amounts allegedly overcharged.
Banco Galicia is analyzing the content and implications of the demand. It is believed that if there is 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.
