Analysis · SGML · Energy & Transportation
A decisive Federal Court of Appeals ruling has reinstated Sigma Lithium's environmental licenses, allowing full resumption of mining and industrial operations. This reverses the September 30 suspension that had halted all production. The company also reaffirmed its 2027 production guidance of 330,000 tonnes of lithium oxide concentrate, stating existing capacity is sufficient with no additional investment needed. The legal victory removes a major overhang that had threatened the company's core operations in Brazil's Lithium Valley. Shares rose 6.3% pre-market after the appeals court upheld its licenses, and the company said it will not need additional capacity to meet its 330,000t 2027 target.
