Cosan (CSAN) Q1 2026 earnings review
Deleveraging Promises Kept, Raízen Bleeding Stopped
Cosan is finally executing the aggressive deleveraging plan the market demanded. While Q1 Net Sales declined 6.5% YoY to R$ 9.0 billion, the real story is on the balance sheet. Management prepaid R$ 6.2 billion in debt and completely wrote down its disastrous investment in Raízen to zero, insulating the HoldCo from further equity-accounted losses as Raízen enters extrajudicial reorganization. Core operations remain highly resilient, with Consolidated EBITDA growing to R$ 3.16 billion and the net loss narrowing by 30% YoY to R$ 1.34 billion. A subsequent R$ 2.08 billion cash injection from the Compass secondary offering in May proves management is serious about fixing the capital structure.
🐂 Bull Case
Total loans and debentures dropped from R$ 64.2B at year-end to R$ 58.5B. Post-quarter, the Compass IPO raised another R$ 2.08B, providing immense liquidity to tackle HoldCo leverage.
By writing the Raízen investment down to zero and citing no legal obligation to fund it, Cosan has amputated its biggest liability. The equity loss drag is officially over.
🐻 Bear Case
Despite debt paydowns, finance expenses actually increased YoY to R$ 2.85 billion in Q1 (from R$ 2.71B), eating all operating profit. The high CDI rate remains a massive headwind.
Rumo Malha Sul took a R$ 168 million impairment hit due to extreme weather damage in Rio Grande do Sul, highlighting the physical climate risks inherent in the logistics portfolio.
⚖️ Verdict: ⚪
Cautiously Optimistic. The underlying businesses (Compass and Rumo) are performing well, and management is relentlessly executing asset sales to fix the balance sheet. However, until the R$ 2.8 billion quarterly finance expense normalizes, bottom-line profitability remains a distant hope.
Key Themes
Execution of Asset Sales: Compass IPO Secures Liquidity
Accelerating. Cosan proved it can monetize assets without a 'fire sale.' In May 2026, the company successfully executed a secondary offering of Compass shares, pricing at R$ 28.00 per share. Cosan pocketed R$ 2.08 billion in net proceeds while retaining control of the asset. This cash injection, combined with the R$ 319 million from the final Vale stake sale in January, provides the exact ammunition needed to continue dismantling HoldCo debt.
Raízen Collapse Reaches Conclusion
Reversing. The long-standing Raízen saga hit rock bottom. With Raízen filing for extrajudicial reorganization in March 2026 due to negative equity of R$ 1.13 billion, Cosan completely zeroed out the investment on its balance sheet. While this destroys historical value, management confirmed they have 'no legal or constructive obligations to provide financial support.' This effectively halts the equity-method bleeding that severely damaged Cosan's 2025 results.
Deleveraging vs. High Rates: The Finance Expense Paradox
Despite paying down R$ 6.2 billion in debt (including the early redemption of 2029, 2030, and 2031 bonds), Cosan's Q1 finance expense worsened, rising from R$ 2.71B in 25Q1 to R$ 2.85B in 26Q1. This directly contradicts the positive deleveraging narrative in the short term. The culprit is a stubbornly high average cost of debt (CDI + 0.97%) and the immediate costs associated with early redemptions. Meaningful bottom-line recovery is impossible until these expenses compress.
Moove Recovers from Fire, Insurance Settled
Stable. The Moove segment has fully normalized following the February 2025 fire. In January 2026, insurers fully settled the remaining R$ 433 million indemnity for material damages and lost profits. Operationally, Moove maintained its profitability, delivering R$ 235 million in Q1 EBITDA (flat YoY), proving the resilience of the new manufacturing ecosystem established after the disaster.
Climate Macro Risk: Malha Sul Impairment
Physical climate risk generated a direct financial hit this quarter. Extreme weather events in Rio Grande do Sul severely damaged Rumo Malha Sul's railway infrastructure. Given high reconstruction costs and uncertainty around the 2027 concession renewal, Cosan recognized a full R$ 168 million impairment loss. This highlights the vulnerability of the infrastructure portfolio to increasing extreme weather patterns.
Biomethane and Energy Transition Traction
Accelerating. The company is steadily advancing its transition portfolio. The Biometano Verde Paulínia S.A. venture (recorded under Compass non-controlling interests) and investments managed through the Climate Tech Fund indicate a strategic pivot toward renewable natural gas and proprietary technology to capture future energy transition margins.
Other KPIs
Accelerating. Despite a 6.5% drop in consolidated Net Sales, Gross Profit grew 7.1% YoY (from R$ 2.87 billion). This margin expansion was driven by a sharp 12.3% reduction in the Cost of Sales, reflecting lower commodity (natural gas) costs and operational efficiencies at Rumo.
In January 2026, Cosan settled its Total Return Swap (TRS) with Santander, acquiring 52.6 million of its own shares for R$ 270.5 million (average cost R$ 5.14). The company immediately began monetizing this, selling 10.1 million shares in March and 21.9 million in April at higher prices (R$ 5.32 - R$ 5.41), generating highly accretive cash inflows.
Guidance
While no quantitative earnings guidance was provided for FY26, management's stated strategic goal remains bringing HoldCo structural debt 'closer to zero.' The R$ 6.2 billion debt prepayment in Q1 and the subsequent R$ 2.08 billion Compass IPO proceeds confirm the company is aggressively executing this trajectory.
Key Questions
Raízen Extrajudicial Reorganization
You have written down the Raízen investment to zero and stated there is no legal obligation to fund it. Under what specific conditions, if any, would Cosan consider injecting fresh capital into Raízen as part of the reorganization plan?
Use of Compass IPO Proceeds
With the R$ 2.08 billion received from the Compass secondary offering in May, what is the exact pecking order for debt retirement? Are you targeting specific high-cost debentures or focusing on extending duration?
Finance Expense Inflection
Despite a massive R$ 6.2 billion debt paydown in Q1, finance expenses increased YoY. At what point in FY26 do you expect the absolute value of quarterly finance expenses to visibly inflect downward?
Malha Sul and Climate Risk
Following the R$ 168 million impairment at Malha Sul due to weather events, how is management adjusting CapEx and insurance strategies across the rest of the Rumo network to mitigate future climate-related disruptions?
