Subject: Material news.

Dear Mr./Mrs.,

It is a pleasure to contact you in my capacity as Head of Market Relations of Central Puerto S.A. (the “Company”).

As informed through material news dated February 17, 2023 (“HR 17/02/23”), Proener S.A.U. (“Proener”), a subsidiary of the Company, entered into a shares purchase and sale contract with Enel Argentina S.A. (“Enel Argentina”) and Enel Américas S.A. (“Enel Américas”) whereby (i) Enel Américas agreed to sell Proener its interest in Inversora Dock Sud S.A. (“IDS”), and (ii) Enel Argentina agreed to sell Proener its interest in Central Dock Sud S.A. (“CDS”) (the “Transaction”), subject to certain precedent conditions, which include that IDS and CDS shareholders shall not exercise their preemptive right.

Within the context of the foregoing, it is informed Proener was informed by Enel Argentina and Enel Américas that YPF Energía Eléctrica S.A. and Pan American Sur S.A. have informed their intention to exercise their preemptive right regarding the shares subject matter of the Transaction.

With no further business at present, I remain sincerely yours,

Leonardo Marinaro
