Sale of Shareholding. Partial Reversal of the Optional Reserve and Distribution of Dividends
Dear Sir/Madam:
I am pleased to address
you, in my capacity as Head of Market Relations of Central Puerto S.A. (the “Company” or “CPSA”),
in order to inform you that:
a)
In the context of a review of the investment in AbraSilver Resource Corp. (“AbraSilver”),
it was concluded that the equity interest held in such company was no longer strategic in nature. As a result, the Company proceeded to
sell one hundred percent (100%) of its shareholding in AbraSilver.
The total amount collected
through such transaction amounted to two hundred twenty-eight million four hundred six thousand eight hundred eighty-five Canadian dollars
(C$228,406,885). It should be noted that the amount originally invested in such interest amounted to thirty-five million seven hundred
forty-one thousand four hundred seventy-seven Canadian dollars (C$35,741,477), resulting in a gain of one hundred ninety-two million six
hundred sixty-five thousand four hundred eight Canadian dollars (C$192,665,408), which was duly recognized in the Company’s financial
statements.
b)
With the funds resulting from the transaction reported in the preceding paragraph, and for purposes
of paying an extraordinary cash dividend, CPSA’s Board of Directors, as of the date hereof, resolved to partially reverse the Optional
Reserve for the Payment of Dividends in the amount of $247,344,290,288, corresponding to the Company’s undistributed, realized and
liquid earnings computed as from January 1, 2025, pursuant to the balance sheet closed and audited as of December 31, 2025, approved by
the General Ordinary Shareholders’ Meeting held on April 30, 2026, equivalent to $164.00 per share (the “Dividend”).
The Dividend will be
paid to shareholders in cash, in Pesos, in accordance with their respective shareholdings.
Pursuant to Section 3.4
(Payment of Profits and Dividends) of the Foreign Exchange Regulations (Texto Ordenado de Exterior y Cambios) of the Central Bank of Argentina,
foreign shareholders will have the option to collect the Dividend in U.S. dollars abroad, to the extent the Company has access to the
MULC, at the exchange rate applicable on the Payment Date, as determined by the financial institution involved in the relevant transaction
(the “Option”); otherwise, they will collect the Dividend in Pesos. To this end, foreign shareholders wishing to exercise
the Option must notify Caja de Valores S.A. between Monday, September 21 and Tuesday, September 22, 2026, from 9:00 a.m. to 3:00 p.m.,
in accordance with the procedures established for such purpose by such entity (the “Exercise Period”). The Option may
not be exercised in part and, accordingly, its exercise shall comprise the entire dividend receivable by each shareholder. The Company
reserves the right to request any documentation it deems reasonable in order to verify a shareholder’s status as a foreign
shareholder, and to declare the Option invalid if such status is not confirmed.
It is expressly stated
that only the shareholdings of record as of September 18, 2026 shall be taken into account for purposes of the dividend payment (the “Cut-off
Date”).
The Dividend Payment
Date is September 25, 2026 (the “Payment Date”).
Finally, shareholders are informed
that, pursuant to the unnumbered paragraph added following Section 25 of Law No. 23,966, as incorporated by Law No. 25,585, the Company
will, where applicable and at the time the Dividend is made available, reimburse itself for the amounts paid on account of the Personal
Property Tax, in its capacity as substitute obligor for the shareholders subject to such tax. Likewise, with respect to income tax, a
7% withholding will be applied to the dividend distribution, where applicable, pursuant to Section 97 of the Income Tax Law.
Yours sincerely,
