PNR’s Redemption
Rio de Janeiro, December 19, 2025, AXIA Energia, further to
the Notice to Shareholders and Material Fact disclosed on December 8, 2025, announces that, as resolved at the Extraordinary General Meeting
held on this date, the compulsory redemption of the class “R” preferred shares - PNR (“Redemption”) was
approved.
The Redemption will be carried out on a compulsory and automatic
basis, immediately after the completion of the mandatory conversions of all currently outstanding preferred shares issued by the Company,
at the price of R$ 1.2994705188032 per redeemed PNR share (“Redemption Value”).
For purposes of the Redemption, the shareholding position
as of the end of December 19, 2025 will be considered as the record date. The payment of the Redemption Value will be made in Brazilian
currency, in a single installment, on January 13, 2026.
1. Brazilian resident investors
Any gains realized by shareholders holding PNR shares who
are residents in Brazil, including individuals and legal entities, investment funds or other entities, as a result of the Redemption may
be subject to the levy income tax and other taxes, pursuant to the legal and regulatory rules applicable to each category of investor.
Such shareholders are responsible for consulting their own advisors to assess the applicable taxation and for payment of any taxes due.
2. Non-resident investors
Pursuant to applicable law, the Company may withhold a portion
of the amount payable to shareholders who are not resident in Brazil, in an amount corresponding to the withholding income tax - IRRF
levied on any capital gain determined as a result of the Redemption.
The capital gain will correspond to the positive difference,
if any, between:
| · | | the Redemption Value;
and |
| · | | the acquisition
cost of the Company’s shares held by the non-resident investor. |
The IRRF will be withheld and collected by the Company in
accordance with the legal and regulatory rules applicable to each type of non-resident investor, subject to the following rates:
| (iii) | | 25%, in the case
of a shareholder resident in a country or dependency with favorable taxation, pursuant to the legislation and regulations of the Brazilian
Federal Revenue Service. Any withholding IRRF that may be withheld and paid by the Company will be deducted from the amount payable to
shareholders as the Redemption Value. |
In order to enable the calculation of any capital gain, non-resident
shareholders must complete and electronically submit to the Company, directly or through their custody agents, the template spreadsheet
attached hereto as Schedule I to this Notice to Shareholders.
The spreadsheet must be completed and sent by e-mail to the
following electronic address: resgate@axia.com.br, with the subject line “PNR Redemption – Capital Gain,” together with
proper and supporting documentation evidencing the reported acquisition cost (e.g., broker statements), which must be attached
to the same email. The information and documents must be sent to the Company by 6:00 p.m. on January 2, 2026.
The Company will rely exclusively on the information and documents
provided by the shareholders for purposes of calculating the capital gain, and such shareholders shall be fully responsible for the truthfulness,
accuracy and completeness of the information provided.
Pursuant to the applicable legislation and regulations of
the Brazilian Federal Revenue Service, the Company will:
| (i) | | deem the acquisition
cost to be zero for non-resident shareholders who fail to submit the information and supporting documentation within the deadline and
in the manner indicated above; and |
| (ii) | | apply a 25% tax
rate to the gains of non-resident shareholders who fail to inform their country or dependency of residence or tax domicile. |
For additional clarifications, shareholders may contact the
Company’s Investor Relations department at the e-mail ri@axia.com.br.
