Cosan S.A. - Q1 2026 Earnings Analysis

Performance Highlights

Cosan posted consolidated net revenue of R$9.03 billion in Q1 2026, down 6.6% from R$9.66 billion in Q1 2025, missing expectations, while the consolidated net loss attributable to owners narrowed to R$1.58 billion from R$1.79 billion a year earlier. The standout metric was consolidated EBITDA of R$3.17 billion, up 59.8% year-on-year from R$1.98 billion, driven by structural improvement across all operating segments after the removal of Raízen from segment reporting.

Rumo was the primary operating driver, growing EBITDA to R$1.58 billion from R$1.35 billion, while Compass contributed R$1.33 billion and Moove added R$236 million, both modestly ahead of the prior year. Gross profit expanded to R$3.08 billion from R$2.87 billion despite lower revenues, reflecting better cost control across logistics and distribution, with group depreciation and amortization stable at R$971 million.

Management Outlook and Forward Catalysts

Management executed approximately R$6.2 billion in debt repayments during the quarter, including early redemption of multiple debenture series and offshore bonds, signalling a deliberate pivot toward balance sheet repair over growth investment. Compass raised R$2.73 billion in new debentures during the period, suggesting selective refinancing continues even as gross leverage contracts, and Rumo maintained R$1.77 billion in capital additions consistent with its ongoing rail infrastructure expansion.

The central investor debate heading into Q2 2026 is the resolution of Raízen's extrajudicial reorganization, filed March 11, 2026, which presents binary outcomes: a successful creditor plan could restore meaningful equity value to Cosan's zero-carried investment, while a disorderly restructuring raises contingent liability and reputational risks. Bears will also scrutinise the R$3.99 billion put option liability on subsidiary shares and the pace at which the holding company's accumulated losses, now R$11.31 billion, can be arrested.
