By Brazil Stock Guide – The government of Minas Gerais has put a clear cutoff price on the privatization of Copasa (CSMG3): R$47.23 per share. That is the newly disclosed minimum price for the sale of the state’s stake in the Brazilian water and sewage utility — and the level at which the transaction either moves ahead or returns to an impasse.
Until now, investors knew there was a floor price for the sale. They did not know the number. By making it public, Minas Gerais has taken the privatization out of the gray zone and put the core question on the table: investors must be willing to pay at least that amount, or the offering will have to be canceled, postponed or redesigned.
The transaction is a secondary share offering. The proceeds will not go to Copasa’s balance sheet, but to the state of Minas Gerais, the selling shareholder. The deal initially involves 171.1 million common shares, with the possibility of adding up to 19 million additional shares.
The R$47.23 floor is, in practice, the break point of the privatization. It is an attempt to bring the government and investors closer after the first round showed there was a limit to market appetite. Strategic investor proposals came below the minimum level initially expected by the government, according to market accounts obtained by Brazil Stock Guide.
The key point is not a lack of interest in Copasa. It is price. Proposals were submitted by a consortium linked to Aegea’s shareholders — Equipav, Itaúsa and GIC, Singapore’s sovereign wealth fund — and by Equatorial Energia, the Brazilian power utility that is also a shareholder in Sabesp, the São Paulo water utility privatized in 2024.
Copasa is a relevant sanitation asset, with a dominant presence in Minas Gerais. But the company also comes with municipal contracts, universal service targets, investment needs and a post-privatization governance structure that requires a long-term commitment from investors.
This is the classic privatization dilemma. If the government sets the floor too high, it protects itself from accusations of selling a public asset too cheaply, but risks making the transaction unworkable. If it accepts a lower price, it improves the chances of execution, but opens the door to political criticism. In Copasa’s case, that tension became more visible because the stock had already risen on expectations of privatization. Around 5 p.m. on Thursday, the shares were up 4.2%, at R$52.88.
The Market Decides
The disclosure of the floor price does not solve the offering. It changes the test. Before, investors were assessing the company without knowing exactly where the official barrier stood. Now they do. That may help organize demand, but it also leaves less room for ambiguity.
If the market decides that R$47.23 is an acceptable price for Copasa, the privatization gains momentum. If investors conclude that the price is still too high given the regulatory, governance, liquidity and execution risks, the deal returns to a stalemate.
The offering also has to pass a second test: sufficient demand. Under the rules of the process, reaching the minimum price is not enough. A minimum number of shares must also be sold for the transaction to move forward. In other words, the privatization depends on two answers at the same time: price and volume.
The new timetable is tight. Interested investors have an additional window to review or submit orders. The retail reservation period starts on June 5, pricing is scheduled for June 11 and settlement is expected on June 16.
