Water and Sanitation
Strategic Profile
SABESP is aggressively expanding infrastructure investment and consolidating regional water assets through acquisitions. In January 2026, the company acquired controlling interest in EMAE (metropolitan water and energy company), and in February 2026 completed R$15.2 billion in capital investments—more than double 2024 levels—while executing a 1:5 stock split in April 2026 and raising capital through blue bonds and debentures to fund continued growth.
Cyborg Score Rationale
SABESP demonstrates strong execution on infrastructure expansion with investments accelerating 2.2x year-over-year (2025 vs 2024). The company is strategically consolidating regional water assets while maintaining dividend capacity and accessing international capital markets. Risks include execution on 2029 universal sanitation targets, currency exposure, and regulatory/political pressures in Brazil.
