Material Changes vs. Prior Period
- Revenue Growth: Driven by a 9.56% tariff adjustment effective May 2023, a 12.8% adjustment from May 2022, and a 3.0% increase in billed volumes. Construction revenue increased 15.1% due to higher investment execution.
- Profitability: Net income rose 12.9% despite a significant increase in net financial expenses (from R$ 372 million to R$ 1.59 billion), primarily due to higher interest rates and exchange variations. Operational performance improved, with costs as a percentage of net revenue (excluding construction) dropping from 73.8% to 69.1%.
- Investments: Capital expenditures reached a historical record of R$ 6.3 billion in 2023 (R$ 2.7 billion for water, R$ 3.6 billion for sewage). The Multi-Year Investment Plan (2024-2028) targets R$ 47.4 billion.
- Debt Structure: Total debt increased slightly, but foreign currency debt decreased by 1.1% to R$ 2.7 billion (14.1% of total debt) due to the depreciation of the USD and Yen against the Real. The company issued R$ 2.94 billion in ESG debentures in March 2024 (post-period).
Guidance, Outlook, and Risks
Management Commentary and Outlook
- Privatization: The State of São Paulo authorized privatization in December 2023. A public consultation on the new concession agreement concluded in March 2024. The process aims to advance universalization goals to 2029 and extend the concession term to 2060.
- Expansion: SABESP won a concession for the municipality of Olímpia in 2023, marking its first expansion outside its traditional state-operated area via a bidding process.
- Operational Goals: The company targets 98% water supply coverage and 93% sewage collection coverage by 2023, with plans to reach 100% water supply and 99% sewage collection coverage by 2028.
Risks and Contingencies
- Internal Control Deficiencies: The auditor identified significant deficiencies in internal controls regarding the measurement of PPP liabilities (São Lourenço) and the physical existence of materials in contract assets. These resulted in accounting adjustments and provisions against income in 2023.
- Legal and Tax Contingencies: Significant provisions exist for labor, environmental, and tax claims. A major tax dispute with the Municipality of São Paulo regarding sewage service taxation remains suspended pending higher court appeals.
- Health Plan Deficits: Post-period events (January 2024) revealed a judicial agreement regarding retiree health plans (Digna Mais), requiring a one-time contribution and ongoing payments to VIVEST, with an estimated impact of R$ 90.2 million in Q1 2024.
- Interest Rate and FX Risk: The company is exposed to interest rate fluctuations (mostly floating rates) and foreign exchange risk on USD and Yen-denominated debt, though it does not use derivative hedges.
Investor Verification Checklist
- Privatization Timeline: Monitor the progress of the public consultation and the finalization of the new concession agreement with URAE-1.
- Internal Control Remediation: Verify management's actions to address the significant deficiencies noted by the auditor regarding PPP liability calculations and inventory of contract assets.
- Debt Covenants: Confirm continued compliance with restrictive covenants, specifically the Net Debt/Adjusted EBITDA ratio (limit 3.50x) and Adjusted EBITDA/Financial Expenses (limit 2.35x).
- Health Plan Liability: Assess the full financial impact of the January 2024 judicial agreement regarding retiree health plans and the migration to VIVEST's Essência plans.
- Tariff Adjustments: Track the implementation of the 2024-2028 tariff cycle and the impact of the "X Factor" (productivity) on future revenue.
