Material Changes vs. Prior Period
- Net Loss Expansion: The consolidated net loss widened significantly to R$2.5 billion from R$0.7 billion in the prior year. This was primarily driven by a R$2.0 billion loss from the equity accounting method of the jointly-owned subsidiary Raízen, due to lower margins, higher interest expenses, and a R$900 million provision for deferred taxes.
- Impairment Reduction: Operating income improved by R$2.6 billion compared to the prior year, largely due to a R$1.9 billion reduction in impairment losses. The prior year included a significant write-off for Rumo Malha Sul assets damaged by extreme weather in Rio Grande do Sul.
- Segment Performance:
- Moove: Revenue declined 8.6% due to a fire at the Rio de Janeiro plant, which temporarily halted production.
- Rumo: Revenue was flat (-0.6%) as strong performance in the Northern operation offset a 23.6% drop in the Southern operation due to weather-related shutdowns.
- Compass: Revenue remained stable (+0.1%) driven by gas sales and managed services.
- Radar: Revenue increased 16% due to the sale of agricultural properties.
- Financial Costs: Net financial expenses decreased by 13.8% to R$3.7 billion, aided by R$5.7 billion in gains from exchange rate variations on foreign debt, partially offset by higher interest costs and mark-to-market losses on derivatives.
Guidance, Outlook, and Risks
- Preliminary Q3 Estimates: For the nine months ended September 30, 2025, Cosan estimates a net loss between R$3.0 billion and R$4.0 billion, a significant deterioration from the R$320.8 million profit in the same period of 2024. This is attributed to higher interest rates (SELIC at 15.0%), lower productivity at Raízen, and the absence of prior-year one-time gains from Vale S.A. and tax credits.
- Strategic Divestitures: Raízen announced the sale of the Santa Elisa plant (approx. R$1.0 billion), distributed generation assets (R$600 million), and two industrial units (R$1.5 billion) to reduce debt and optimize the portfolio. Additionally, the Grupo Nós joint venture with FEMSA was terminated via a share exchange.
- Corporate Governance: A new Shareholders' Agreement is expected, granting Anchor Investors significant board representation and veto rights on strategic matters. The company is also considering the potential delisting of its ADSs from the NYSE and deregistration with the SEC.
- Risks: Key risks include exposure to interest rate volatility (CDI/SELIC), foreign exchange fluctuations, extreme weather events impacting logistics and agriculture, and regulatory changes in Brazil. The company maintains compliance with all financial covenants.
Investor Verification Checklist
- Raízen Performance: Verify the impact of the R$900 million deferred tax provision and the sustainability of margins in the sugar/ethanol sector given weather disruptions.
- Debt Management: Confirm the execution of announced asset sales (Santa Elisa, Rio Brilhante, Passa Tempo) and their actual contribution to debt reduction.
- Moove Recovery: Assess the timeline for full production recovery at the Rio de Janeiro plant following the fire.
- Delisting Intent: Monitor official announcements regarding the potential delisting of ADSs from the NYSE and the implications for U.S. investor liquidity.
- Interest Rate Sensitivity: Evaluate the impact of the elevated SELIC rate (15.0%) on future financial expenses and cash flow generation.
