PART I

Item 1. Exchange Act Reporting History

A. AXIA Energia S.A. (the “Company”) became subject to reporting obligations under Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), in connection with the listing on the New York Stock Exchange (the “NYSE”) of American Depositary Shares (“ADSs”) representing its common shares (the “Common Shares,” and the ADSs representing the Common Shares, the “Common ADSs”) and its Class “B” preferred shares (the “Class B Preferred Shares,” and the ADSs representing the Class B Preferred Shares, the “Preferred ADSs”), on September 26, 2008, in connection with which the Company filed a registration statement on Form 20-F . The Company’s Class B Preferred Shares and Preferred ADSs were exchanged in a mandatory exchange offer (the “Exchange Offer”) for the Company’s Class “B1” preferred shares (the “Class B1 Preferred Shares”) or Class “B1” preferred ADRs (the “Class B1 Preferred ADSs”), as applicable, on December 22, 2025. The Exchange Offer was exempt from registration under the U.S. federal securities laws by Section 3(a)(9) of the Securities Act of 1933, as amended. Following and as a result of the Exchange Offer, the Preferred ADS ceased trading on the NYSE and the Class B1 Preferred ADS began so trading. The NYSE filed a Form 25-NSE with the U.S. Securities and Exchange Commission (the “SEC”) on December 29, 2025, with regard to the Exchange Offer and the Class B Preferred ADSs

On December 12, 2025, the Company filed a registration statement on Form F-6 with respect to the ADSs representing the Company’s Class “C” preferred shares (the “Class C Preferred Shares,” and the ADS representing the Class C Preferred Shares, the “Class C Preferred ADSs”) with the SEC, which was declared effective on December 23, 2025.

On April 1, 2026, the Company’s shareholders approved the Company's migration to the Novo Mercado listing segment of B3 S.A. – Brasil, Bolsa, Balcão (“B3”) and, as a result, the exchange of the Class B1 Preferred Shares into Common Shares (the “Common Share Exchange”).

On June 10, 2026, the holders of the Class B1 Preferred Shares and Class B1 Preferred ADS received Common Shares and Common ADS, as applicable, following the completion of the Common Share Exchange. On the same date, the NYSE filed a Form 25-NSE with the SEC with respect to the Class B1 Preferred ADSs, and, on June 22, 2026, the Company filed a Form 15F with respect to such ADSs.

B. The Company has filed or submitted all reports required under Section 13(a) or Section 15(d) of the Exchange Act and corresponding SEC rules for the 12 months preceding the filing of this Form 15F. The Company has filed at least one annual report under Section 13(a) of the Exchange Act.

Item 2. Recent United States Market Activity

The Common Shares and Class C Preferred Shares (collectively, the “Shares”) , the Common ADSs and the Class C Preferred ADSs have not been sold in the United States in a registered offering under the Securities Act of 1933, as amended, during the 12 months preceding the filing of this Form 15F.

Item 3. Foreign Listing and Primary Trading Market

A. The Company currently maintains the listing of the Shares in the Novo Mercado listing segment of B3, located in Brazil. Such foreign exchange is the primary trading market of the Shares.

B. The Common Shares started trading on the B3 on September 7, 1971 and the Class C Preferred Shares started trading in the B3 on December 22, 2025. The Common Shares have traded in the B3 for at least the 12 months preceding the filing of this Form 15F. The Company has maintained the listing of the Shares since the initial date of listing.
