Material Changes vs. Prior Period
- Revenue Drivers: Adjusted net revenue grew 6.7% driven by an 8.7% increase in net price (rate phase-in) and a 1.1% volume increase. Growth was partially offset by lower per capita consumption due to milder weather and a shift in customer mix toward low-income discount rates.
- Cost Pressures: Operating costs and expenses rose 24.5% year-over-year. Key drivers included:
- Services: +39.0% increase due to investments in customer service (call centers, marketing, new stores).
- General Expenses: +977% increase, primarily due to a lack of favorable legal rulings recorded in the prior year (approx. R$200 million benefit in 2Q25).
- Treatment Supplies: +97% increase driven by inflationary pressures on key inputs from geopolitical factors.
- Financial Result: Net financial result deteriorated significantly (-R$1,076 mn vs -R$118 mn in 2Q25) due to a higher net debt balance (R$34 billion vs R$23 billion) and higher funding costs.
- Capex Execution: Investments totaled R$3.7 billion in 2Q26, with a focus on sewage infrastructure (R$2.68 billion) and water (R$1.05 billion).
Guidance, Outlook, and Risks
- Full Year Capex: Management expects to invest close to R$20 billion in capital expenditures for the full year 2026 to support universalization and operational resilience.
- Operational Targets: The company remains confident in delivering its "U-Factor" targets for the year.
- Strategic Focus: Continued acceleration of the transformation plan, including digital upgrades and proactive customer engagement, which may result in higher upfront costs but aim for long-term efficiency.
- Risks and Contingencies:
- Inflation: Ongoing pressure on chemical inputs and general supplies due to the geopolitical environment.
- Weather Sensitivity: Revenue is sensitive to temperature variations affecting per capita consumption.
- Debt Levels: Significant increase in net debt impacting financial results.
Investor Verification Checklist
- Debt Trajectory: Verify the sustainability of the R$34 billion net debt level and the impact of rising funding costs on future margins.
- Cost Normalization: Assess whether the 24.5% cost increase is a one-time step-up due to transformation investments or a structural shift in the cost base.
- Weather Impact: Monitor consumption trends to determine if the "milder temperature" effect in 2Q26 is a temporary anomaly or a trend affecting volume growth.
- Legal Accruals: Review the volatility in general expenses related to legal rulings, as the 977% increase was driven by the absence of prior-year benefits.
- Capex Efficiency: Confirm that the R$20 billion annual Capex plan aligns with projected cash flows and debt servicing capabilities.
