New procedure for redemption or conversion of
PNC shares
Rio de Janeiro, August 5, 2026, AXIA
Energia S.A. (“Company” or “AXIA Energia”) hereby informs, in addition to the Market Announcement and the Material
Fact disclosed on June 9 and June 14, 2026, respectively, that, following the successful completion of the first redemption or conversion
transaction of the Class “C” preferred shares (“PNC Shares”), the deadlines applicable to future transactions
have been revised.
The new deadlines will be counted based
on the number of trading sessions on B3 S.A. – Brasil, Bolsa, Balcão (“B3”), consisting of 9 trading sessions
for the delivery of common shares resulting from the conversion and 13 trading sessions for the payment of the redemption amount, replacing
the 12 and 16 business-day periods adopted in the first transaction.
The deadlines applicable to future transactions
will be as follows:
·
D0 - Announcement of the transaction: The Board of Directors will
resolve on the amount to be redeemed, and the redemption value per PNC Share will correspond to the closing price of the Company's common
shares on the trading session immediately preceding the respective resolution date (D-1).
·
D+2 tradings - Record date: The record date for determining
shareholders eligible for redemption or conversion will correspond to the second trading session following the disclosure of the respective
transaction.
If the announcement is made before the opening
of trading on D0, the record date will correspond to the trading session of the business day immediately following the announcement, considering
the shareholding position as of the close of that trading session.
If the transaction announcement is made
after the close of trading on D0, the record date will correspond to the second trading session following the announcement, considering
the shareholding position as of the close of that trading session.
·
D+3 tradings - Ex-rights date: PNC Shares will begin trading ex-rights
as of the third trading session following the announcement of the transaction.
·
D+3 a D+6 tradings - Tax treatment for non-resident investors: non-resident

redeemed. |
Election channels:

The PNC Shares underlying such ADRs will be mandatorily redeemed, and Citibank N.A., as depositary, will receive the redemption proceeds
and distribute them to the respective ADR holders.
Payment to ADR holders will be made within
up to seven business days following the redemption payment date applicable to holders of PNC Shares traded on B3.
