Subject: Material News. Rectification of the values of the Company’s Optional Reserves informed in the Shareholders’ Meeting Minutes dated September 15, 2023.

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”) so as to inform that during the last Shareholders’ Meeting held on September 15 of the current year (the “Meeting”), shareholders were informed that: a) the amount of the Optional Reserve reached ARS 423,378,553,738 and b) the amount of the Optional Reserve for the payment of dividends reached ARS 48,676,863,668, in both cases expressed in constant currency as of August 31, 2023 as per the last rate published by INDEC (National Statistics Bureau) as of the date of the Shareholders’ Meeting as per the regulations in force.

Avda. Tomás A. Edison 2701 – C1104BAB – City of Buenos Aires – Argentina

Telephone (54 11) 4317 5000 – Fax (54 11) 4317 5099

It is hereby informed that after the Meeting was held, the fact that such amounts are incorrect was noticed since the update calculation was made on the basis of balances as per financial statements as of June 30, 2023 and the updating period January-August 2023 period was included when the only one that should have been included is the July-August 2023 period. For such reason, the Company’s Board of Directors corrected such amounts putting on record that as of the date of the Meeting (September 15, 2023), the amount of the Optional Reserve reached ARS 281,080,210,661, while the amount of the Optional Reserve for the payment of dividends reached ARS 32,316,476,527, in both cases expressed in constant currency as of August 31, 2023, as per the last rate published by INDEC as of the date of the Shareholders’ Meeting as per the regulations in force.

It is hereby clarified that the foregoing does not affect what was decided in the mentioned Meeting.

Lastly, we inform that the Company will publish the Minutes with the correct amounts.

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