NOTICE TO
THE MARKET Voluntary Delisting of ADSs from the New York Stock Exchange Rio de Janeiro, July 6, 2026 - AXIA Energia S.A., previously
known as “Centrais Elétricas Brasileiras S.A. - Eletrobras” (the “Company” or “AXIA Energia”),
hereby informs its shareholders and the market in general that, as previously announced on April 1, 2026, and pursuant to authorization
from its board of directors, the Company is proceeding with the voluntary delisting (the “Delisting”) of all of the Company’s
outstanding common American Depositary Shares (the “Common ADSs”) and all outstanding Class C preferred American Depositary
Shares (the “Class C Preferred ADSs” and, together with the Common ADSs, the “ADSs”) from the New York Stock
Exchange (the “NYSE”). Following the Delisting, the Company’s shares will remain listed on B3, which will continue
to serve as the Company’s primary trading venue. The ADSs subject to the Delisting are: (i) Common ADSs (Ticker: AXIA; CUSIP: 15234Q207);
and (ii) Class C Preferred ADSs (Ticker: AXIA PRC; CUSIP: 15236F100). • Reasons for Delisting. The Delisting aims to consolidate
the Company’s liquidity in the Brazilian market, considering that the ADSs currently represent only approximately 2.5% of the Company’s
outstanding shares. • Expected Timeline. The last day of trading of the ADSs on the NYSE is expected to be on or about August 6,
2026, at market close (the “Delisting Date”). The Delisting is expected to become effective 10 days after the filing of Form
25 with the U.S. Securities and Exchange Commission (the ”SEC”). Following the Delisting, the Company intends to file a Form
15F with the SEC to deregister its securities and suspend its reporting obligations under the Securities Exchange Act of 1934, as amended
(the “Exchange Act”). Following such filing, certain of the Company’s reporting obligations under the Exchange Act,
including its obligations to file or furnish Forms 20-F and 6-K, as applicable, will be suspended immediately. During the following 90-day
period, the Company and its directors and officers will continue to comply with any Exchange Act reporting obligations that are not suspended
by the Form 15F filing, including any Section 16(a) beneficial ownership reporting obligations. The suspension of all of the Company’s
reporting obligations under the Exchange Act is expected to become effective no later than 90 days after the Form 15F is filed, assuming
no objections from the SEC. • Continued Trading in the United States. Following the Delisting Date, the ADSs are expected to continue
to be available for trading in the United States through a Level 1 sponsored ADR program maintained by Citibank, N.A. (“Citibank”),
as depositary, on the over-the-counter market. No action is required to be taken by ADS holders at this time. Certain statements in this
notice, including statements regarding the Delisting and the withdrawal of registration, the expected Delisting Date and other expected
dates, regulatory processes, continued trading availability and reporting obligations, are forward-looking statements and are subject
to known and unknown risks and uncertainties. These risks and uncertainties include, among others, risks relating to the timing and completion
of the Delisting and withdrawal of registration under Section 12(b) of the Exchange Act, the filing and effectiveness of Forms 15F and
25, any action by the SEC, NYSE or Citibank, the availability and liquidity of the Company’s ADSs in the over-the-counter market,
depositary notice and operational processes, and other risks described in the Company’s annual report and other documents filed
with the SEC. This notice is furnished for informational purposes and does not constitute an offer to sell or a solicitation of an offer
to buy any securities. Investor Relations: Eduardo Haiama - Vice President of Finance and Investor Relations General Investor Relations:
