Dear Mr./Mrs.,

I am hereby writing to you, in my capacity as Head of Market Relations of Central Puerto S.A. ("CPSA" or the "Company"), in accordance with the applicable regulations, to inform you that the Company, through Proener S.A.U. (a company wholly controlled by CPSA), signed a subscription agreement for shares of the company AbraSilver Resource Corp. (a company listed on the Canadian Stock Exchange) ("AbraSilver"), which owns the Diablillos silver-gold project located in northwestern Argentina.

The completion of the transaction is subject to certain conditions, including but not limited to acceptance by the TSX Venture Exchange and is expected to be met on or about February 6, 2025. CPSA's current shareholding, through Proener S.A.U., in AbraSilver is 4%, which, upon completion of the transaction, will amount to 9.9%.

AbraSilver owns 100% of the shares of the Diablillos silver and gold project located in the provinces of Salta and Catamarca. The current proven resources and

the estimated mineral reserves at Diablillos are 42.3 Mt grades 91 g/t Ag and 0.81 g/t Au, containing approximately 124 Moz silver and 1.1 Moz gold. The funds from the aforementioned subscription of shares will be used, among other destinations, to carry out the feasibility study of the Diablillos project, which will be completed by December. This will allow the start date of construction of the mine to be defined.

Kind regards
