Central Puerto S.A.

What it is

Central Puerto makes electricity and sells it into Argentina’s grid. It is the country’s largest private power producer, running 16 plants with about 6,938 MW of installed capacity — enough to cover a meaningful slice of national demand.

The company was constituted in 1992 as a direct result of Argentina’s energy-sector privatisation, taking over thermal plants from the former state utility SEGBA in Buenos Aires. Its fleet now spans gas, hydro, wind and solar.

It also runs two side businesses that hedge against Argentina’s wild currency swings: forestry, with more than 160,000 hectares of pine and eucalyptus, and a newer push into lithium mining.

Who owns it

This is the unusual part. After a 2025 reorganisation, no single shareholder is in charge.

As a consequence of the merger between Central Puerto and Operating S.A., Hidroneuquén S.A. and Sociedad Argentina de Energía S.A., none of the shareholders of Central Puerto holds a controlling interest.

In plain terms, the shares are widely scattered — what the market calls a high free float. The shares trade on the Buenos Aires Stock Exchange and on the New York Stock Exchange under the ticker CEPU since February 2018, with the majority of shares available for public trading.

The structured data shows insiders holding about 36% and institutions about 8% — a reminder that “no controlling shareholder” still leaves large blocks in known hands.

Who runs it

The chairman is Osvaldo Arturo Reca, named president of the board in May 2025; the board appointed Osvaldo Arturo Reca as President and Miguel Dodero as Vice President.

Day-to-day, Fernando Roberto Bonnet is chief executive and general manager, a role held since April 2021, and Enrique Terraneo is chief financial officer, appointed in April 2021.

The money, in plain words

Central Puerto keeps a lot of each sale as profit. For 2025 the company reported net income of ARS 346 million (US$237 k) (the data shows ARS 346 billion, about US$237 million) on sales of ARS 1.10 trillion (about US$751 million) — a net profit margin of 36.7%, very high for a utility.

Sales grew from ARS 971 billion (US$665 mn) to ARS 1.10 trillion (US$753 mn) year on year, up about 13% (our calculation) — though Argentina’s high inflation makes such figures hard to read.

For every peso owners have invested, the company earns about 19 back a year — a return on equity of 19.3%, strong. The shares look cheap: a price-to-earnings ratio of 8.0, meaning you pay eight pesos for each peso of yearly profit.

On dividends, the data shows no yield. The board proposed channeling retained earnings into an optional reserve for future dividends or share buybacks.

So cash is being held back, not paid out, for now.

What it is doing now

The big recent move is into batteries. Central Puerto won 205 MW from the Alma GBA tender for two battery storage projects.

These battery systems are scheduled to enter commercial operation in the first half of 2027.

It is also still buying solar. Its 2025 growth included the Cafayate solar farm and the completion of the Brigadier López combined cycle.

A rule change helps too: the government’s stated aim is to reduce its intervention in prices and contracts, giving private players greater freedom and legal security.

What to watch

• Argentina’s currency: most costs and the share price move with the peso, so US-dollar value can swing fast.
• Whether the held-back profit turns into actual dividends or buybacks.
• The lithium and forestry bets — do they grow into real businesses, or stay sidelines?
• Energy reform: if the government truly steps back from setting prices, margins could firm up further.
