Proposed Corporate Name Change to Axia Energia S.A.

Centrais Elétricas Brasileiras S.A. – Eletrobras (the “Company”) informs its shareholders and the market that management has submitted for shareholder approval at the Annual and Extraordinary General Meeting scheduled for April 15, 2026 (the “AEGM”) a proposal to amend the Company’s bylaws to change its corporate name to “Axia Energia S.A.”. The proposal requires the approval of an absolute majority of the Company’s outstanding common shares and class “C” preferred shares.

If approved at the AEGM and, following registration of the minutes of the AEGM with the Commercial Registry of the State of Rio de Janeiro, the Company intends to adopt the new legal name. This change is consistent with the brand transition first announced on October 22, 2025, and, as previously reported, reflects the conviction that the future of energy will be built by solid, reliable companies capable of catalyzing businesses that drive sustainable economic development.

Trading Symbols and Identifiers

As previously disclosed, in connection with the brand transition, the Company’s trading symbols on B3 and the New York Stock Exchange were updated effective November 10, 2025, as follows:

Ticker B3

Ticker NYSE

No Change to Operations or Governance

If approved, the change of corporate name would not affect the Company’s corporate purpose, share capital, governance, operations, assets, liabilities, contractual or other obligations or regulatory commitments.
