Watch for the Federal Court of Appeals ruling on the Emergency Motion For Suspensive Relief. The outcome is binary: if granted, operations could resume quickly; if denied, the company will appeal to superior courts, extending the suspension. Monitor any updates on the court's decision timeline, especially after the October 25 election conclusion.

Executive Summary
Sigma Lithium temporarily suspended all mining and industrial production on September 30, 2026, due to a 15-day delay by the Federal Court of Appeals in reviewing its emergency legal defense against a preliminary injunction that challenged its environmental licenses. The company maintains its FY 2027 guidance of 330,000 tonnes of lithium oxide concentrate but will postpone its 12-month guidance of 240,000 tonnes by three months. The suspension creates material operational uncertainty with no clear timeline for resolution, compounded by Brazil's general elections concluding October 25, which may further delay the court ruling.
Key Facts
- All mining and industrial production temporarily suspended as of September 30, 2026
- Suspension caused by a 15-day delay by the Federal Court of Appeals in reviewing the company's Emergency Motion For Suspensive Relief
- Company maintains FY 2027 guidance of 330,000 tonnes of lithium oxide concentrate
- Company postpones 12-month guidance of 240,000 tonnes by 3 months
- Commercial and recycling operations continue, generating cash flow to self-fund during suspension
- Second round of Brazil's general elections concludes October 25, potentially delaying legal decision
- Company will seek secondary appeal in superior federal courts if negative ruling from Federal Court of Appeals
- Preliminary injunction was issued by a local federal court in a lawsuit filed by NGO Ngolo, challenging environmental licenses
Financial Impact
Complete production halt with no end date; company expects to self-fund via commercial/recycling operations but revenue from primary lithium concentrate production is zero during suspension
Risk Factors
- Prolonged production suspension if Federal Court of Appeals rules against the company
- Negative ruling could lead to extended legal process through superior federal courts, delaying operations for months
- Brazilian general elections may introduce political bias or further delay in legal proceedings
- Loss of customer contracts or market share during extended suspension
- Cash burn from maintaining operations without primary production revenue
