Ref.: CEPU-ECOGAS Corporate Reorganization. Relevant Fact.
From my consideration:
I am hereby writing to you, in my capacity as Head
of Market Relations of Central Puerto S.A. (hereinafter, the "Company" or "CEPU"), in relation
to the Split-off-merger operation (the "Split-off-Merger") between the Company and ECOGAS Inversiones S.A. ("ECOGAS"),
to inform the Shareholders that, after obtaining due authorizations from the National Securities Commission (the "CNV")
and the Buenos Aires Stock Exchange ("BCBA"), in relation to the Split-off-merger operation (the "Split-Off-Merger")
between the Company and ECOGAS Inversiones S.A. ("ECOGAS"), as authorized by the CEPU and ECOGAS Extraordinary General
Shareholders' Meetings of May 22, 2025, the Company will proceed with the Split-Off on October 1, 2025.
For this reason, the investing public is informed
that, in accordance with the terms of the definitive corporate reorganization agreement signed on June 17, 2025 between the Company and
ECOGAS (the "Definitive Corporate Reorganization Agreement"), the following events will take place on October 1, 2025,
among others:
1)
ECOGAS will receive the entirety of the Split-Off CEPU Equity, consisting of: (a) 59,986,580 Class "A" book-entry ordinary
shares, with a par value of $1 each and with the right to one vote per share of ECOGAS; (b) 33,369 non-endorsable registered ordinary
shares, of $1 par value each and entitled to one vote per share of Energía Sudamericana S.A.; (c) 27,597,032 Class "B"
book-entry ordinary shares, with a par value of $1 each and entitled to one vote per share of Distribuidora de Gas del Centro S.A.; and
(d) the sum of $305,000,000 in cash;
2)
All Class "A" shares of ECOGAS (59,986,580 shares with a par value of $1 each and with the right to one vote per share)
will be cancelled;
3)
80,973,264 new Class "D" shares of ECOGAS will be issued, with a par value of $1 each and with the right to one vote
per share, to be distributed among CEPU shareholders based on their shareholdings in said company according to the register of Caja de
Valores S.A. as of the date of registration, which will be September 26, 2025 (the "Registration Date")."), and
to the Exchange Ratio determined in one Class "D" share of ECOGAS for every 18.6694 shares held in CEPU. Fractions of shares
will not be delivered.
As indicated in the Corporate Reorganization
Agreement, the new shares of ECOGAS to be delivered to those shareholders of CEPU who hold their interests in such company through CEPU's
American Depositary Receipts program ("CEPU ADRs") as of the Record Date, will be delivered to JPMorgan Chase Bank,
N.A. ("JPMorgan") in its capacity as depositary of the CEPU ADR program and, if they are not capable of being delivered
in the form of certificates representing such New ECOGAS Shares, they will be retained by JPMorgan, in its capacity as depositary of the
CEPU ADR program, which will dispose of them, in accordance with the provisions of the Amended and Restated Deposit Agreement dated
October 16, 2023 between CEPU, JPMorgan, and CEPU ADR holders, and any agreements or instructions JPMorgan enters into with, or receives
from, CEPU.
In this regard, ECOGAS is in the process of creating
a program of Global Depositary Receipts of ECOGAS (the "GDR Program"), which will represent Global Depositary
Shares ("GDSs") whose assets will have as an underlying part of the new shares of ECOGAS, in order to offer investors
who have their shares in CEPU through CEPU ADRs the possibility of receiving securities representing the New Shares abroad and grant them
a reasonable period of approximately 90 days from the date of the Restricted Deposit Agreement to carry out operations aimed at receiving
their shares in the local market, at their discretion.
Given that the Split-Off-Merger is an operation
exempt from registration with the U.S. Securities Exchange Commission ("SEC"), the Program must be restricted, and may
only be accessed by investors who have their shares in CEPU through ADRs as of the registration date determined by JPMorgan and who submit
the certifications required pursuant to Regulation S and Rule 144 A of the Securities Act of the United States of America. 1933 (Securities
Act) and investors who, after the initial distribution, acquire GDRs issued as a result of the Split-Off-Merger through the trading
mechanisms and with the applicable restrictions.
Consequently, the GDRs will be delivered to
those holders of CEPU ADRs that are eligible under the standards mentioned, to the extent that they have complied with the certifications
and other documentation required by JPMorgan, in the times and forms that said entity provided accordingly.
4)
The amount corresponding to the fraction of undelivered share will be transferred to the shareholders of CEPU on the Registration
Date, in accordance with the registry of Caja de Valores S.A. and as applicable to each, valued in accordance with the price of the Class
"D" share of ECOGAS at the close of the Registration Date;
5)
The new share capital of ECOGAS will be $250,217,264, as a result of the cancellation and issuance of shares referred to in points
2) and 3), and own shares may remain in the possession of ECOGAS as a result of fractions of shares not delivered.
Kind regards
