Companhia de Saneamento Basico do Estado de Sao Paulo SABESP
Companhia de Saneamento Básico do Estado de São Paulo, commonly known as SABESP, stands as a crucial pillar in Brazil’s public utility landscape, particularly within São Paulo state. Born out of a necessity to tackle one of urban life’s most essential requirements – water supply and wastewater treatment – SABESP has transcended mere utility services to weave itself into the fabric of São Paulo's growth. The company, established in 1973, is akin to an engineer of urban sustainability, deftly managing a vast labyrinth of reservoirs, aqueducts, and sewage systems. It provides clean and safe water to millions, handling both its purification and distribution. Embedded in its operational core is an extensive infrastructure that not only facilitates the smooth transit of water but also ensures that wastewater is treated and returned to the environment in an ecologically responsible manner.
SABESP generates revenue primarily through the provision of these water and wastewater services, with its financial health hinging on its ability to efficiently serve a sprawling population in an ever-expanding urban area. Customers, ranging from residential households to large industrial complexes, are billed based on their usage, creating a direct correlation between water consumption patterns and the company’s income streams. Over the years, SABESP has navigated Brazil's economic fluctuations, regulatory dynamics, and various environmental challenges, all while striving to expand its reach and enhance service quality. The company’s ability to maintain an intricate balance between meeting immediate urban demands and strategizing long-term infrastructure developments speaks to its pivotal role not only as a provider of essential services but also as a guardian of the region’s water resources.

Profitability: Adjusted EBITDA expanded to BRL 3.4 billion in the quarter (60% margin) and BRL 13.2 billion for the full year, +13% Q/Q year‑ago and +17% year‑ago respectively, driven by cost discipline and efficiencies.
Revenue: Adjusted net revenue was BRL 5.7 billion in the quarter (up 2.1% YoY) and BRL 22.2 billion for 2025 (up 2.2% YoY) — growth mainly from removing large‑client discounts and volume from new connections, partly offset by expanded subsidized rates.
Investment surge: CapEx reached BRL 15.2 billion in 2025 (BRL 4.8 billion in Q4), more than double 2024, accelerating universalization and water‑safety projects; original cycle was BRL 70 billion at 2022 prices and management is updating/bringing forward parts of that plan.
Cash & leverage: Gross debt BRL 40 billion, net debt BRL 28 billion, cash BRL 12 billion (covers >3 years of amortizations); net debt / adjusted EBITDA ~2.2x and weighted average debt maturity ~5.6 years.
Operational progress: Water production 789 million m3 in the quarter; connections ~9.5 million water (+0.4% YoY) and 8.3 million sewage (+0.8% YoY); universalization targets met early with major projects delivered (3.8 million people gained sewage treatment in 2025).
Regulatory / legal wins: Captured ~BRL 450 million from removal of large‑client discounts in 2025, with only BRL 50–100 million of injunctions remaining and ~70% of injunctions already decided in SABESP's favor.
Acquisition update: Completed acquisition of controlling EMAE shares and now holds ~98% of EMAE common shares; tender offer for remaining voting shares expected in April.
