Material Changes vs. Prior Period
- Revenue Growth: Net revenue increased 4.7% YoY in 2Q25, driven by a 5.6% growth in Mobile Service Revenue (MSR). Postpaid revenue expanded 10.7% YoY, while Prepaid revenue declined 10.6% YoY due to migration to higher-value plans and lower recharge frequency.
- Profitability: Normalized Net Income grew 25.0% YoY in 2Q25. Normalized EBITDA margin reached a record 50.8% for a second quarter, up 0.8 percentage points YoY.
- Cost Management: Normalized Operating Costs and Expenses grew 3.1% YoY, below the inflation rate (5.35%). Selling & Marketing expenses decreased 5.0% YoY due to digitalization efficiencies. Network and Interconnection expenses rose 15.6% YoY.
- Financial Position: Total debt increased to R$16.8 billion, primarily driven by higher lease liabilities, partially offset by a reduction in financial debt. Cash and marketable securities rose 65.3% YoY to R$5.5 billion.
- Partnership Termination: The partnership with Banco C6 was terminated in March 2025, impacting Customer Platform Revenue (down 5.0% YoY in 2Q25) and resulting in the write-off of related subscription warrants.
Guidance, Outlook, and Risks
- Outlook: Management highlights consistent cash generation and disciplined cost control. Investments remain focused on 5G network expansion, particularly in São Paulo and Minas Gerais.
- Dividends: The Board approved R$320 million in Interest on Shareholders' Equity for payment in October 2025. Additional dividends of R$2.05 billion related to fiscal year 2024 were approved in March 2025.
- Legal and Regulatory Risks:
- TFF (Operating Supervision Fee): Payments have been suspended since 2020 due to injunctions. As of June 30, 2025, the outstanding obligation is R$3.8 billion (R$2.9 billion principal + R$903 million interest).
- Legal Provisions: Provisions for legal and administrative proceedings totaled R$1.48 billion. Significant litigation includes consumer protection actions and tax disputes (Federal, State, and Municipal).
- Regulatory Compliance: The company is subject to ANATEL proceedings regarding quality indicators and service obligations.
- Unusual Items: The filing includes non-recurring impacts related to the settlement of the dispute with Banco C6 and adjustments to legal provisions following favorable court decisions (e.g., a R$169 million reversal in a Public Civil Action).
Investor Verification Checklist
- TFF Liability Status: Verify the current legal status of the suspended R$3.8 billion TFF payment obligation and potential cash flow impacts if injunctions are lifted.
- Lease Liability Growth: Confirm the trajectory of lease liabilities, which drove the increase in total debt, and assess the impact on future interest expenses.
- Postpaid vs. Prepaid Mix: Monitor the sustainability of Postpaid revenue growth (10.7% YoY) against the decline in Prepaid revenue (-10.6% YoY) and the associated churn rates.
- Legal Provision Reversals: Review the details of the R$169 million provision reversal regarding the Public Civil Action to understand the precedent for future litigation outcomes.
- 5G Capex Efficiency: Assess whether the R$2.2 billion Capex in 6M25 is delivering expected returns in terms of network coverage and ARPU growth.
