SABESP (SBSP) Q2 2026: 9.4% Revenue Growth Amidst Rising Costs and Accelerated Universal Access Investment
SABESP advanced its universal access program with robust revenue growth despite cost pressures and weather impacts. Elevated investments in customer experience and safety protocols signal a strategic pivot prioritizing long-term operational resilience. The company’s strong backlog and funding position underpin confidence in meeting ambitious infrastructure goals through 2029.
Summary
- Investment Acceleration: Universalization efforts and infrastructure expansion continue at unprecedented scale.
- Operational Complexity: Rising costs and enhanced safety measures reflect growing execution challenges.
- Strategic Customer Focus: Significant commercial investments aim to improve service amid transformation.
Business Overview
SABESP is Brazil’s leading water and sanitation utility, providing water supply and sewage services primarily in the state of São Paulo. The company generates revenue through regulated tariffs applied to its customer base, which includes approximately 9.5 million water and 8.2 million sewage connections. Its core business segments encompass water production, sewage collection, and treatment, with ongoing investments focused on universal access and infrastructure modernization.
Performance Analysis
In the second quarter of 2026, SABESP reported adjusted net revenue growth of 9.4% year-over-year, driven mainly by tariff increases and customer base expansion. However, water production declined 4.3%, influenced by milder weather and operational adjustments such as pressure management to enhance system resilience. Despite revenue growth, adjusted EBITDA decreased 2.3%, reflecting inflationary pressures, increased investments in customer service, and the absence of prior year legal accrual reversals amounting to BRL 230 million.
The company’s net income declined due to higher financial expenses linked to elevated net debt used to fund its accelerated universal access program. Capital expenditures rose 16% year-over-year to BRL 7.5 billion year-to-date, supported by a substantial backlog exceeding BRL 40 billion through 2029. This investment surge underpins SABESP’s commitment to expanding sanitation coverage and system resilience, with recent commissioning of sewage treatment plants adding significant capacity.
- Revenue Drivers: Price increases accounted for 8.7% of growth, with volume and new connections contributing modestly despite negative weather impacts.
- Cost Pressures: Inflationary effects, particularly on chemicals linked to geopolitical factors, and expanded customer service initiatives weighed on margins.
- Capital Investment: Backlog and execution of large-scale projects demonstrate operational momentum despite seasonality and execution complexity.
Overall, SABESP’s financial performance reflects a transitional phase where accelerated growth and investment are accompanied by rising costs and operational complexity, setting the stage for future scale benefits and improved service delivery.
Executive Commentary
"The acceleration of our investment program cannot come at the expense of safety. As our construction program grows, our safety standards, controls, and capabilities must grow with it."
Carlos Piani, CEO
"About half of the increased commercial costs will be recovered through tariff cycles, with approximately 20 to 25 percent expected to remain as a structural increase."
Daniel Szlak, CFO
Strategic Positioning
1. Universal Access and Infrastructure Expansion
SABESP is aggressively advancing its universalization program, targeting 99% coverage by 2029. The company’s CAPEX execution is ramping up with over 1,500 active construction sites and a backlog exceeding BRL 40 billion. Investments focus heavily on sewage treatment and water supply infrastructure, with a two-thirds allocation to sewage projects. The recent commissioning of new treatment plants and the initiation of countryside projects demonstrate progress in expanding service reach and capacity.
2. Customer Experience Transformation
Recognizing the increased demand on customer-facing operations, SABESP has significantly expanded its commercial plan. This includes hiring over 200 new personnel, opening and upgrading physical service centers, and enhancing call center capabilities. These efforts aim to reduce complaint volumes and improve service responsiveness, particularly for low-income customers benefiting from social tariffs that have nearly doubled since privatization.
3. Safety and Operational Resilience
In response to recent incidents and the scaling complexity of its operations, SABESP has raised safety standards beyond regulatory requirements. Measures include expanded underground infrastructure monitoring zones, tripling field inspectors, mandatory training, and use of AI technologies for risk detection. An operational safety group reporting directly to the CEO underscores the company’s commitment to embedding safety into its growth trajectory.
4. Financial Strategy and Capital Allocation
SABESP has proactively secured funding for its investment program, raising approximately BRL 14 billion early in 2026 and expecting to meet full-year targets by Q3. The company maintains a net debt to EBITDA ratio of 2.5x, deemed appropriate for its infrastructure scale-up phase. Management anticipates that cash flow generation will improve by 2028, reducing reliance on debt financing for ongoing CAPEX.
5. Efficiency and Cost Management
While personnel expenses remain controlled, the company faces inflationary pressures on chemicals and power costs. SABESP is pursuing technological initiatives such as smart metering and integrated operations centers to drive productivity gains. Cultural shifts emphasizing frugality and operational ownership complement these initiatives, aiming to deliver sustainable cost efficiencies alongside growth.
Key Considerations
SABESP’s Q2 2026 results reflect a company navigating rapid growth and transformation, balancing investment scale with operational challenges.
- Weather Sensitivity: Milder temperatures and operational pressure management reduced water consumption, highlighting volume volatility risks.
- Tariff and Regulatory Dynamics: Price increases underpin revenue growth, but regulatory reforms and discounts to large clients create revenue gaps to be addressed.
- Commercial Investment Impact: Elevated spending on customer service is partly temporary, with management expecting normalization post-2026.
- Safety Investments: Enhanced safety protocols increase operational costs but are critical to sustaining construction pace and workforce expansion.
- Capital Program Seasonality: CAPEX execution is back-ended, with acceleration expected in H2 2026 and into 2027, driven by countryside universalization projects.
Risks
SABESP faces risks from regulatory uncertainty, particularly regarding tariff reviews and recognition of investments in the regulatory asset base. Inflationary pressures on input costs, especially chemicals and power, may persist, challenging margin recovery. Operational complexity and safety incidents could disrupt project timelines and increase costs. Weather variability remains a material factor affecting consumption and revenue.
Forward Outlook
For Q3 2026, SABESP expects to continue ramping CAPEX execution, supported by a robust project backlog and contract pipeline. The company anticipates partial recovery of temporary cost pressures related to ERP implementation and chemical prices. Commercial investments will persist but are expected to normalize over time.
- CAPEX is projected to accelerate in the second half of 2026 toward year-end targets of approximately BRL 20 billion.
- Revenue growth will continue to be supported by tariff adjustments and customer base expansion, offset by weather effects.
Management maintains full-year guidance, emphasizing disciplined capital allocation and a commitment to improving customer experience and operational resilience.
Takeaways
SABESP’s Q2 2026 earnings reveal a utility in the midst of a large-scale transformation supported by aggressive investments and strategic initiatives.
- Financial Performance Reflects Transition: Revenue growth is robust but offset by cost inflation and investments in customer service and safety, compressing EBITDA margins temporarily.
- Strategic Execution Is Intensifying: The company is scaling universal access aggressively with a strong project backlog and expanding workforce, increasing operational complexity and risk.
- Future Focus on Efficiency and Customer Experience: Investments in technology and culture aim to drive productivity gains and service improvements, critical for sustaining growth and profitability beyond the current investment cycle.
Conclusion
SABESP’s Q2 2026 results underscore a company balancing rapid growth and investment with operational challenges. The strong backlog and funding position provide confidence in meeting universal access goals, while rising costs and safety initiatives highlight execution risks. Investors should monitor progress on efficiency gains and regulatory clarity as key drivers of future financial stability.
