## Copasa Privatization – Brazil (2026)
### Overview
Two bidder groups submitted offers to become the strategic investor in Companhia de Saneamento de Minas Gerais (Copasa), advancing the Minas Gerais state government's plan to privatize one of Brazil's largest water and sewage utilities, according to people familiar with the matter (Bloomberg, May 25, 2026). The bids were submitted by groups linked to Aegea investors and Equatorial, representing two of Brazil's leading infrastructure operators.
### About Copasa
Copasa is a publicly traded, state-controlled water and sewage company headquartered in Belo Horizonte, Minas Gerais. It serves millions of customers across the state and is one of Brazil's largest sanitation utilities by revenue and coverage. The Minas Gerais state government holds a controlling stake and initiated the privatization process as part of broader fiscal consolidation efforts.
### Bidders
- **Aegea Saneamento**: Brazil's largest private water and sewage operator, backed by major infrastructure investors including GIC and others. Aegea has aggressively expanded through acquisitions of state utility concessions.
- **Equatorial Energia**: A major Brazilian energy and infrastructure conglomerate that has diversified into sanitation, acquiring state utility concessions in Amapá, Pará, and Goiás.
Both groups reportedly submitted bids, according to people familiar with the matter (Bloomberg, May 25, 2026).
### Strategic Importance
Copasa's privatization is described as one of Brazil's biggest deals of 2026 (Bloomberg, May 25, 2026). For investors and attorneys, the transaction represents:
- A major test of Brazil's sanitation sector privatization framework under the 2020 Sanitation Legal Framework (Marco Legal do Saneamento).
- A precedent for other state-level utility privatizations, particularly in larger Brazilian states.
- Significant M&A activity in the Brazilian infrastructure sector with potential antitrust scrutiny given Aegea's market position.
### Open Questions
- Final selection timeline and state approval process.
- Regulatory conditions attached to any transfer of control.
- Antitrust review by CADE given Aegea's dominant position in the privatized sanitation market.
- Pricing and valuation given Copasa's listed status on the São Paulo exchange.
