Re.: Relevant event.

I write to you as Head of Market Relations at Banco Macro S.A. (the "Bank"), in order to inform that the Bank has acquired 49.9939% of the Class B shares held by the protector partners of "Fintech SGR" and therefore currently holds 24.99% of the capital stock and votes of such company.

In addition, please be advised that the Bank has decided to purchase shares representing 50% of the capital stock and votes of "Finova S.A.". The main purpose of Finova S.A. is to develop and market the website www.facturbo.com.ar, a digital solution that allows customers to negotiate credit instruments issued and accepted by large companies in favor of MiPyMES (small and medium-sized companies).

Sincerely,
