Iberdrola Tightens Its Grip On Brazil As B3 Loses Listed Champions

Brazil’s stock market is shrinking. In recent years, companies such as Zamp, Santos Brasil and Wilson Sons have launched buyouts or restructurings that end with their shares leaving the B3 exchange, blaming high interest rates, heavy rules and depressed valuations.

Iberdrola is also delisting a company — but in order to own more of Brazil, not less. The Spanish utility already controls Neoenergia, Brazil’s largest electricity distributor by number of customers.

It now wants to buy the remaining 16 percent it does not own for R$ 32.50 ($6) per share, spending about R$ 6.5 billion ($1.2 billion) and valuing the group at roughly R$ 39 billion ($7.2 billion).

The price matches what Iberdrola paid in September, when it spent around R$ 11.5 billion ($2.1 billion) to purchase the stake held by pension fund Previ and lift its holding to about 84 percent. Neoenergia is a classic infrastructure play.

It supplies electricity to roughly 40 million people in 18 states and the Federal District, with a portfolio that includes a large share of renewable generation. Its core business is regulated “wires and poles” — networks whose returns are set by formula over long periods.

Strategic Moves Amid Brazil’s Market Noise

In the first nine months of 2025, the company invested about R$ 7.6 billion ($1.4 billion) in its networks and generated profits of R$ 3.6 billion ($700 million), numbers that help explain why the parent wants full control.

To keep leverage in check, Neoenergia has been trimming non-core assets. Shortly before the new offer, it agreed to sell the Dardanelos hydropower plant in Mato Grosso to France’s EDF for roughly R$2.5 billion ($500 million), while retaining a minority stake.

The deal pushes net debt to around three and a half times annual cash flow — a level still compatible with a regulated utility focused on stable returns. Globally, Iberdrola is withdrawing from more politicised or uncertain environments while concentrating on rule-based networks.

It has taken its U.S. arm Avangrid off the New York Stock Exchange and is selling its Mexican assets, redirecting capital into countries where regulation is clearer and contracts are more predictable.

For Brazil and for foreign readers, the message is subtle but important. The local equity market is losing solid, cash-generating names just when the country needs deeper capital markets.

At the same time, a disciplined foreign operator is quietly locking up strategic infrastructure, confident that regulated tariffs, long-term demand and a more market-friendly approach to utilities will outlast today’s political noise.
