By Brazil Stock Guide – Iberdrola Energía S.A. has finalized the purchase of Caixa de Previdência dos Funcionários do Banco do Brasil’s (Previ) stake in Neoenergia S.A. (B3: NEOE3), bringing its ownership in the Brazilian utility to 83.8%. The transaction, disclosed on Friday (Oct. 31), marks the conclusion of a process initiated in September and formally dissolves the shareholders’ agreement between Iberdrola and Previ that had governed Neoenergia since 2017.
The deal consolidates Iberdrola’s control over one of Brazil’s largest electricity groups, which operates five distributors, 18 transmission lines, and a renewable portfolio exceeding 3.8 GW. Neoenergia serves about 40 million people across six states and the Federal District, making Brazil Iberdrola’s most significant market outside Europe. The Spanish group has invested heavily in the country’s regulated grids and renewables as part of its global decarbonization and electrification strategy.
With its stake now approaching 84%, Iberdrola could soon be in a position to launch a tender offer (OPA) to take Neoenergia private — a scenario increasingly discussed among analysts. XP, BTG Pactual, and Citi have highlighted the potential for delisting as a key short-term catalyst, noting that Iberdrola’s control structure and strong liquidity would facilitate a buyout if strategic conditions align. Citi estimated that a premium offer could add nearly 20% upside to Neoenergia’s share price.
For Previ, Latin America’s largest pension fund, the sale concluded a long-term investment and aligns with its broader effort to rebalance its portfolio toward more diversified and liquid assets. Neoenergia said it will continue to update shareholders on any developments related to the transaction and corporate structure going forward.
