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 and its Class “B” preferred shares (“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.

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 3. Foreign Listing and Primary Trading Market

A.

The Company’s common ADSs and Class “C” preferred ADSs currently trade on the NYSE in the form of American Depositary Receipts (“ADRs”); the Class B1 Preferred ADSs ceased trading on the NYSE on June 5, 2026.
