Companhia de Saneamento Básico do Estado de São Paulo – SABESP announced that the São Paulo State Public Services Regulatory Agency (ARSESP) has validated its Regulatory Asset Base (RAB) for 2023 and 2024. The company reports a validated 2023 RAB of R$ 78.5 billion at June 2024 values and a validated 2024 RAB of R$ 88.0 billion at December 2024 values. These figures reflect adjustments such as reclassifications, construction margin, interest differences between IFRS and regulatory criteria, one-off asset revaluations, write-offs, inflation effects and depreciation, as summarized in the table. Management notes that forward-looking statements about future performance and strategies are subject to risks and uncertainties that could cause actual results to differ materially from current expectations.
Sabesp (SBS) furnished 3Q25 results via Form 6‑K, showing steady operating progress alongside heavy investment. Reported net income was R$2,158.6 million with EPS of R$3.16, which reflects prior-year accounting effects from concession asset bifurcation. On a comparable basis, adjusted EPS was R$1.88, up from R$1.72 a year ago, and adjusted EBITDA rose about 15% year over year.
The company invested R$4.0 billion in the quarter and R$10.4 billion year to date, focused on universalization projects; active connections increased, supported by 148,000 new units versus 3Q24. Operating costs fell, with OPEX down 15% year over year to R$2,270 million, aided by lower electricity expenses, leaner headcount, and provision reversals. Net revenue was R$9,425 million, including construction revenue tied to concession works.
Balance sheet liquidity improved with cash and cash equivalents of R$4,969 million as of September 30, 2025. Borrowings and financings totaled R$34,926 million, equity was R$42,710 million, and net debt was R$23,276 million. Results also included effects from court‑ordered debt payments, with approvals totaling R$1,950 million and R$1,118 million received.
Sabesp (SBS) filed a 6-K reporting 3Q25 results. Adjusted earnings were R$1.88 per share, up from R$1.72 a year ago. Reported EPS was R$3.16 versus R$8.94 in 3Q24, with the prior year inflated by the concession “financial asset” bifurcation. Management cited a 15% year-over-year increase in adjusted EBITDA and continued progress on universalization.
Investment and operations accelerated. The company invested R$4.0 billion in the quarter (a record) and R$10.4 billion year-to-date, adding 148,000 new active connections. Adjusted net sanitation revenue was R$5,468 million, essentially flat year over year, as higher volumes were offset by customer mix and FAUSP effects. Operating expenses fell 15% to R$2,270 million on efficiency measures including lower electricity costs and G&A reductions.
Non-recurring items were material. Court-ordered debt payments (precatórios) totaled R$1.950 billion, with R$1.118 billion received; a R$1,461 million monetary adjustment boosted financial results.

Companhia de Saneamento Básico do Estado de São Paulo – SABESP plans to become the controlling shareholder of EMAE – Empresa Metropolitana de Águas e Energia S.A. through two negotiated share purchase agreements. SABESP agreed to buy 74.9% of EMAE’s common shares at R$59.33 per share from a fiduciary agent representing debentureholders of Phoenix Água e Energia S.A., and 66.8% of EMAE’s preferred shares at R$32.07 per share from Eletrobras.
After closing and regulatory and antitrust approvals, SABESP expects to hold 70.1% of EMAE’s total share capital, for an aggregate acquisition cost of R$1,131,460,783.00. The company highlights two main strategic benefits: stronger water security in the São Paulo Metropolitan Region through integration of the Guarapiranga and Billings systems, and access to EMAE’s portfolio of power generation assets with long-term, inflation-indexed revenue contracts, which management believes supports financial stability and long-term value creation.
Sabesp (SBS) reports a pending legal dispute with Subcondominio Eldorado Business Tower over commercial charging schemes.
