Key Financial Metrics (Consolidated)

All figures in thousands of Brazilian Reais (R$), unless otherwise noted.

Material Changes vs. Prior Period

• Profitability Improvement: Net loss attributable to owners narrowed significantly from R$ 2.73 billion in the prior year to R$ 1.90 billion, driven by improved EBITDA (up 39% to R$ 6.69 billion) despite a slight decline in net sales (-1.7%).
• Debt Reduction: Total consolidated debt decreased by approximately R$ 10 billion (from R$ 64.2 billion to R$ 54.3 billion) due to aggressive early repayments and optional acquisition offers totaling over R$ 8.6 billion in principal during the period.
• Impairment Charges: The company recognized R$ 569 million in impairment losses, primarily related to the Rumo segment (R$ 336 million) due to infrastructure damage from extreme climate events and the Parent Company (R$ 233 million) related to assets held for sale.
• Financial Results: Net finance costs remained high at R$ 4.21 billion, though slightly lower than the R$ 3.71 billion in the prior period, impacted by interest rates and foreign exchange variations.

Guidance, Outlook, Risks, and Unusual Items

• Raízen Joint Venture Restructuring: Raízen S.A. filed for Extrajudicial Restructuring. Cosan's investment is reduced to zero on the balance sheet. The restructuring plan, approved in July 2026, involves debt-to-equity swaps and capital increases by Shell and Aguassanta, which may dilute Cosan's interest and potentially lead to a loss of joint control.
• Compass IPO: Cosan completed a secondary offering of Compass shares, receiving R$ 2.29 billion. Cosan retained control (76.18%). The transaction was recorded as an equity transaction with no impact on the income statement.
• Rumo Malha Oeste Concession: The concession contract for Rumo Malha Oeste was terminated on June 30, 2026. A transitional regime is in place for asset preservation. Management expects no significant impact on consolidated results pending final accounting reconciliation.
• Legal and Tax Contingencies: Significant tax litigation remains, with R$ 6.13 billion in assessed values under discussion where acceptance is likely, and R$ 16.89 billion in possible losses (tax, civil, environmental, labor).
• Subsequent Events:
  • Rumo issued R$ 500 million in new debentures (July 2026).
  • Board approved the total spin-off of Radar II (effective Oct 1, 2026).
  • Letter of intent signed to sell TUP Porto São Luís for R$ 300 million.

Investor Verification Checklist

• Raízen Dilution Impact: Verify the final equity percentage retained by Cosan in Raízen following the restructuring plan implementation and the potential accounting reclassification from joint venture to associate or financial asset.
• Rumo Malha Oeste Settlement: Monitor the final settlement of accounts with the Federal Government regarding the terminated concession to confirm the absence of unexpected liabilities.
• Debt Maturity Profile: Review the liquidity risk given the R$ 8.57 billion in debt due within one year against the R$ 13.36 billion cash balance.
• Tax Litigation Resolution: Track the status of the R$ 6.13 billion in probable tax contingencies, particularly regarding PIS/COFINS credits and goodwill amortization.
• Compass Dividend Policy: Assess the impact of Compass's new public status on future dividend distributions to Cosan.
