Cosan S.A. reported a 2Q26 net loss of R$320 million, a 66% improvement versus the R$946 million loss in 2Q25. Results include a R$233 million impairment on the Port São Luís asset held for sale, partially offset by lower financial expenses and reduced general and administrative costs.
Expanded net debt was R$9.2 billion, down 20% versus 1Q26 and 47% versus 2Q25, supported by a secondary IPO of Compass that generated about R$2.3 billion for Cosan and R$8.8 billion of early debt settlements in 6M26. The Debt Service Coverage Ratio fell to 0.2x, and the company now guides for DSCR to converge to 0.8x–1.2x by year-end 2026, assuming R$1.3–1.8 billion in 2026 dividends and equivalent distributions.
Cosan S.A. reported consolidated net revenue of R$ 19.8 billion for the six months ended June 30, 2026, slightly below the prior-year period. EBITDA rose strongly to R$ 6.69 billion, driven mainly by Compass, Rumo and Moove, but finance costs and impairments kept results weak.
The loss attributable to Cosan’s shareholders narrowed to R$ 1.90 billion from R$ 2.73 billion a year earlier, while non-controlling interests recorded R$ 746 million of profit. Cash and cash equivalents fell from R$ 27.24 billion to R$ 13.36 billion as the group executed large early redemptions of debentures and senior notes and settled a total return swap on its own shares. Cosan monetized part of its portfolio through the Compass IPO, receiving R$ 2.29 billion in a secondary offering while retaining 76.18% control, and sold its remaining stake in Vale. The investment in joint venture Raízen remains at zero; accumulated losses not recognized by Cosan reached R$ 9.54 billion, and Raízen entered a court-approved Extrajudicial Restructuring Plan that reprofiles about R$ 61.4 billion of unsecured financial debt, which may later change Cosan’s level of influence and accounting treatment.
