Companhia de Saneamento Básico do Estado de São Paulo - SABESP (SBS) - Marketing Mix: Price

You're looking at how Companhia de Saneamento Básico do Estado de São Paulo - SABESP (SBS) prices its essential water and sewage services, which is heavily dictated by regulatory oversight. The entire pricing framework is built around the regulated tariff structure approved by ARSESP, the state regulator for these public services.

The most immediate change you need to note is the forthcoming adjustment. ARSESP has given the green light for an average user tariff increase of 6.5%, which Companhia de Saneamento Básico do Estado de São Paulo - SABESP (SBS) will apply starting January 1, 2026. This user-facing hike is calculated after incorporating inflation and tax effects. To put that in context for the regulatory side, the equilibrium rate, which is the benchmark Companhia de Saneamento Básico do Estado de São Paulo - SABESP (SBS) aims for to balance revenues and investments, was raised by 10.6% in late 2025. This difference between the equilibrium rate uplift and the user rate is key to understanding the regulatory mechanism.

The company is committed to maintaining accessibility for the most vulnerable. Companhia de Saneamento Básico do Estado de São Paulo - SABESP (SBS) keeps a low social tariff for eligible residential users, where the rate for consumption between 0-10 m³ remains at R$11.14. This is part of a broader social inclusion strategy that now benefits 1.8 million families. Anyway, this is balanced against other structural adjustments.

Here are some key components driving the equilibrium rate change, which is the contractual benchmark:

• Inflation adjustment (IPCA from July 2024 to October 2025) accounted for 6.11% of the rate change.
• A positive adjustment of 3.54% compensated for a lag in Regulatory Asset Base recognition since August 2024.
• Positive market effects, driven by volume and consumption mix changes, contributed a substantial 3.41% boost.
• A negative compensatory adjustment for the 4th regulatory cycle (2021-2024) was -5.37%.
• The removal of rate coverage for the Alto Tietê PPP resulted in a cost reduction of approximately R$130 million factored into the rate.

To show you how the new structure translates across customer types in the GT-O directorate, look at these specific brackets, effective January 1, 2026:

Still, you should know that commercial and industrial customers are facing sharper tariff adjustments compared to the average residential user. This reflects a gradual correction of structural distortions where, historically, these higher-consumption groups benefited from cross-subsidies from residential households. The new structure is designed to move toward cost recovery across all segments, meaning corporate users absorb some of the most significant nominal increases to achieve better cost alignment.
