Sigma Lithium Celebrated 1,010 Days Without Accidents and Zero Fatalities; Operations on Track to Reach 240ktpy Lithium Oxide; Categorically Responds to Inaccurate Media Reports
Sigma Lithium Stabilizes Operations Amid Regulatory Clarity, Yet Short-Term Hedging Signals Caution

Executive Summary
- Sigma Lithium reported a safety milestone of 1,010 days without accidents with lost time injury and zero fatalities in 14 years.
- The company confirmed operations are on track to reach production guidance of 240,000 tonnes per year (tpy) of lithium oxide concentrate.
- Management categorically refuted media reports claiming waste piles were "banned" by the Ministry of Labor and Employment (MLE), citing a technical statement from Brazil's mining regulator (ANM) attesting to safety.
- An administrative enquiry by the MLE resulted in an immaterial fine of R$10,000 (approx US$2,000).
- The company noted an unusual increase in put option volumes at $21.50 expiring May 15, 2026, coinciding with negative media reports and share price volatility.
- Deployment of heavy equipment (60-tonne trucks, 75-tonne excavators) across four shifts is ongoing to support ramp-up.
Material Impact
- The regulatory clarification regarding waste piles was previously addressed in February 2026 when ANM issued a technical statement confirming safety; this news serves as a reaffirmation rather than new information.
- Production guidance of 240ktpy aligns with previous announcements from March and February 2026, indicating no deviation from the established operational thesis.
- The mention of unusual put option volume introduces a negative sentiment factor, suggesting short-term bearish positioning or hedging by investors despite positive operational news.
- The safety milestone is positive but incremental for a company with a long operating history; it does not fundamentally alter valuation metrics.
- Overall impact is stabilizing rather than transformative, preventing potential downside from lingering rumors without providing new upside catalysts to justify further price appreciation beyond current levels.
