Controlling shareholding

As a consequence of the merger between Central Puerto S.A., in its capacity as parent company and Operating S.A. (“OPER”), Hidroneuquén S.A. (“HNQ”) and Sociedad Argentina de Energía S.A. (“SADESA”), all in their capacity as acquired companies and, as a consequence of the corresponding acquired companies’ shares swap, none of the shareholders of Central Puerto S.A. holds a controlling interest.

Finally, it is important to highlight the fact that share capital is under public offering and it is listed in the Buenos Aires Stock Exchange (“BCBA”) and; since February 2, 2018, in the New York Stock Exchange (“NYSE”). Therefore, shareholding may experience variations, which the company may not be aware of.

Yours sincerely,
