Sigma Lithium has signed an agreement with Synergy Capital to extend the maturity of its US$100 million senior secured debt by six months, moving the repayment date from December 2026 to June 2027. The interest rate remains unchanged at SOFR plus 6.95% per annum, and existing covenants are maintained. This extension defers final repayment, providing additional financial flexibility as the company ramps up production following the October 5 restart of operations after environmental licenses were reinstated. Since restarting, Sigma Lithium has produced 7,090 tonnes of lithium oxide concentrate. Total debt has been reduced by approximately 40% over the past two years to US$125 million as of October 21, 2026. The company aims to scale annualized production to 330,000 tonnes by year-end 2027. Sigma Lithium is a producer of lithium oxide concentrate in Brazil.
A Federal Court of Appeals upheld Sigma Lithium's environmental licenses, overturning a local emergency ruling that had suspended them. This benchmark legal decision enables the full resumption of mining-industrial operations at the Grota do Cirilo project in Brazil. The court recognized the significant economic importance of the company to the Vale do Jequitinhonha region, noting it supports approximately 19,000 direct and indirect jobs across 12 municipalities. Sigma Lithium confirmed that existing mine and processing capacity is sufficient to meet its guidance for annualized lithium oxide concentrate production of 330,000 tonnes by year-end 2027 without requiring additional capital expenditure. The company operates as the largest producer of industrial-mineral lithium oxide concentrate in the Americas.
Sigma Lithium Corporation temporarily suspended all mining and industrial production at its Grota do Cirilo complex on September 30, 2026, following a 15-day delay by the Federal Court of Appeals in reviewing its legal defense against an environmental injunction. The company maintains its full-year 2027 guidance of 330,000 tonnes of lithium oxide concentrate but has postponed its 12-month production target of 240,000 tonnes by three months due to the suspension. Commercial and recycling operations continue to generate cash flow while the legal dispute proceeds. This operational halt poses significant near-term risk to revenue and regional economic impact in Minas Gerais, Brazil. Sigma Lithium operates as a producer of industrial-mineral lithium oxide concentrate for battery materials.
Sigma Lithium was selected by Nasdaq to ring the closing bell during United Nations Climate Week in New York, marking five years since its listing and recognizing its sustainability leadership in critical minerals. The company also disclosed a preliminary judicial ruling concerning its environmental licenses related to surface rights and potential land expropriation from small-scale farmers near its Grota do Cirilo operation in Brazil. Sigma Lithium strongly contests the ruling, citing lack of due process and technical evidence showing operations are more than 12 kilometers from the claimed Quilombola community, exceeding the relevant legal threshold. The company confirmed that mining and industrial operations continue normally and that its mineral rights remain unaffected by the dispute, which carries a potential R$100,000 penalty for non-compliance.
