Ref.: Relevant fact

To whom it may concern,

I am pleased to address you in my capacity as Capital Markets Relations Officer of Central Puerto S.A. (the “Company”), in order to inform you that: (i) within the framework of the share repurchase plan approved by the Company on October 11, 2022, and (ii) pursuant to the provisions of Article 67 of Capital Markets Law No. 26,831, the automatic cancellation of 252,034 common shares, each entitled to one vote per share, has taken place.

Since their acquisition (carried out between October 20 and November 23, 2022), the aforementioned treasury shares remained in the Company’s portfolio without having been disposed of, nor has any shareholders’ meeting resolution been adopted regarding their allocation, as required by the applicable regulations.

As a result, the Company’s share capital is automatically reduced by an amount equal to the nominal value of the canceled shares, and the new share capital amounts to AR$ 1,513,770,222, represented by 1,513,770,222 common shares, each entitled to one (1) vote and with a nominal value of AR$ 1 per share.

Consequently, the Company’s Board of Directors has resolved to proceed with the registration of the share capital reduction with the Public Registry.

Yours faithfully,

Leonardo Marinaro
