The legal win removes a material overhang that had halted operations since September 8. With operations resumed and 2027 guidance intact, the key catalyst to watch is the Phase 2 expansion to 580,000 tonnes and Phase 3 to 830,000 tonnes, which the company plans to resume in 2027.

Executive Summary
Sigma Lithium announces it has resumed mining-industrial operations after a Federal Court of Appeals overturned a local judge's emergency ruling that had suspended the company's environmental licenses. The company reaffirms its 2027 production guidance of 330,000 tonnes of lithium oxide concentrate, citing existing capacity. The filing also notes the conclusion of Brazil's general elections in Minas Gerais with a pro-lithium industry governor elected, which management believes reduces political headwinds.
Key Facts
- Federal Court of Appeals reinstated Sigma Lithium's environmental licenses, enabling full resumption of mining-industrial operations
- Company reaffirms 2027 guidance of 330,000 tonnes annualized lithium oxide concentrate production by year-end 2027
- Existing Mine 1 and Cleantech Industrial Plant capacity sufficient to meet guidance without additional capacity
- Plant previously demonstrated capability to produce above 950 tonnes per day after Q4 2024 technological upgrade
- Pro-lithium industry governor elected in Minas Gerais in first round with majority votes
- Jequitinhonha Valley region secured 18 seats across state and federal legislatures, with 95% supporting development agenda
- Company supports approximately 19,000 direct and indirect jobs and around 80,000 family members across 12 municipalities

Financial Impact
Resumption of operations removes existential operational risk; 330,000t annual production guidance maintained. No financial figures provided in filing.
Risk Factors
- Ngolo association may continue legal challenges despite this appellate ruling
- Brazil presidential election second round on October 25 could shift political landscape
- Lithium price volatility could impact economics of production guidance
- Phase 2 and Phase 3 expansion plans remain subject to future permitting and financing
