Why CSAN dropped

Cosan is a Brazilian holding company whose biggest business, the Raízen fuel/sugar joint venture with Shell, filed for an out-of-court debt reorganization in March 2026 covering about R$65 billion of debt after years of cash burn, forcing Cosan to write its stake down to zero and post billions in losses.
