Brasil │20030-900 Approval of Migration to the Novo Mercado Rio de Janeiro, April 1, 2026 - Centrais Elétricas Brasileiras
S/A - Eletrobras (“Company” or “AXIA Energia”), in continuation of the material fact disclosed on February 18,
2026, the Company informs that, at the shareholders’ meetings held on this date, all matters necessary for the advancement of the
migration to the Novo Mercado of B3 S.A. – Brasil, Bolsa, Balcão (B3) were approved—notably, the conversion of Class
“A1” (PNA1) and Class “B1” (PNB1) preferred shares, the authorization for the migration to the Novo Mercado, and
the amendment of the Company’s bylaws. On May 4, 2026, the deadline expires for the exercise of withdrawal rights by PNA1 and PNB1
shareholders who did not approve the respective conversions at the special shareholders’ meetings. After confirmation by the Company
of the number of shares that may be reimbursed, all PNA1 and PNB1 shares will be converted into common shares. The effective migration
to the Novo Mercado remains subject, among other matters, to review and approval by B3, pursuant to applicable regulations, as well as
to the operational procedures for the conversion of PNA1 and PNB1 shares. The migration to the Novo Mercado represents a relevant step
in the simplification of the Company’s capital structure, the increase in the liquidity of its shares, and the continuous evolution
of its corporate governance practices. Eduardo Haiama Vice-President of Finance and Investor Relations
