2026 Governance Report Rio de Janeiro, July 23, 2026, AXIA Energia S.A. (“Company” or “AXIA Energia”), informs
that has filled, on this date, its 2026 Governance report on the Company’s website and with the Brazilian Securities and Exchange
Commission (CVM). AXIA Energia achieved over 98% adherence to the practices recommended by the Brazilian Corporate Governance Code, reinforcing
its commitment to the continuous enhancement of its corporate governance framework. The key governance milestone in 2026 was the completion
of the Company's migration to B3's Novo Mercado segment in June 2026, together with the adoption of the "one share, one vote" principle,
while preserving the special class share (golden share) held by the Brazilian Federal Government, in accordance with applicable legislation.
Among the Company's main governance practices are: • A Board of Directors composed of 70% independent members; • Bylaw requirements
for the nomination and election of officers and directors that are more stringent than those established by law, including specific criteria
regarding disqualifications, overboarding, loss of independence, and conflicts of interest; • Annual evaluations of the Board of
Directors and Executive Management, including assessments of directors' independence and incentive mechanisms aligned with value creation
for the Company and its shareholders; and • A Compliance Program and Whistleblower Channel aligned with leading practices of integrity,
ethics, and compliance. AXIA Energia will continue to strengthen its corporate governance practices with a focus on sustainable value
creation. Eduardo Haiama Vice President of Finance and Investor Relations
