Material Changes vs. Prior Period
- Revenue Growth: Net revenue increased 18.3% year-over-year, driven by a 40.3% surge in construction revenues (R$ 3.63 billion) and an 8.5% increase in net sanitation revenue. Sanitation revenue growth was fueled by a 11.9% net price increase (tariff phase-in and commercial initiatives) and a 2.4% volume increase from new connections.
- Cost Efficiency: Operating expenses (OPEX) decreased 7.7% to R$ 2.24 billion. This was primarily due to a 13% reduction in headcount (saving R$ 170 million in personnel costs) and energy cost savings from migrating 86% of consumption to the free market.
- Financial Expenses: Net financial expenses increased significantly to R$ 1.03 billion (from R$ 0.59 billion in Q1 2025), reflecting higher interest rates and inflation adjustments on debt, partially offset by higher financial income from investments.
- Balance Sheet Expansion: Total assets grew by R$ 12.5 billion, largely due to the consolidation of EMAE assets (R$ 1.78 billion) and increased contract assets from construction projects. Total borrowings increased to R$ 51.6 billion, driven by new funding of R$ 13.9 billion to support CapEx and the acquisition.
Guidance, Outlook, and Risks
- Operational Targets: Management reports outperforming U-Factor benchmarks for the 2024-2026 cycle, with targets of 87% for water supply, 77% for sewage collection, and 71% for sewage treatment.
- Investment Program: CapEx of R$ 3.7 billion in Q1 2026 is focused on universalization targets. The company expects to sustain this investment momentum throughout 2026.
- Acquisition Integration: SABESP is assessing the feasibility of incorporating all remaining shares of EMAE not yet held by SABESP (Share Incorporation) to simplify corporate structure. A Unified Public Tender Offer has been submitted to the CVM.
- Risks and Contingencies:
- Financial Risk: Significant exposure to foreign currency (USD, EUR, Yen) and interest rate fluctuations. The company utilizes derivative instruments (swaps) to hedge these risks.
- Legal/Environmental: The company faces substantial contingent liabilities, including R$ 5.24 billion in environmental claims and R$ 1.93 billion in tax claims.
- Operational: A temporary reduction in billing volumes occurred in March 2026 due to a two-day cutover for the migration to SAP S/4HANA, expected to be recovered in subsequent months.
Investor Verification Checklist
- EMAE Acquisition Details: Verify the final purchase price allocation (PPA) and the status of the proposed Share Incorporation to determine the final ownership structure and potential dilution.
- Debt Servicing Capacity: Monitor the Adjusted EBITDA/Adjusted Financial Expense ratio (currently 3.50x covenant) given the sharp increase in financial expenses and net debt.
- Regulatory Tariff Adjustments: Confirm the sustainability of the 11.9% net price increase and the impact of the expansion of subsidized rate consumers on future margins.
- Construction Revenue Recognition: Review the accounting treatment of the R$ 3.63 billion in construction revenue to ensure it aligns with the company's long-term concession asset strategy.
- Legal Provisions: Assess the adequacy of provisions for the R$ 9.9 billion in total contingent liabilities, particularly environmental and tax claims.
