Sigma Lithium Pauses Operations While Awaiting Appeals Court Ruling

02:00 PM EDT, 10/01/2026 (MT Newswires) -- Sigma Lithium (SGML) said Thursday it has temporarily suspended its mining and industrial production operations due to a 15-day delay by Brazil's Federal Court of Appeals in reviewing the company's emergency motion for suspensive relief. The company said it still expects to deliver 330,000 metric tons of lithium oxide concentrate in 2027, but will postpone by three months its 12-month guidance of 240,000 metric tons. The company challenged a preliminary emergency injunction related to a lawsuit filed by Ngolo non-governmental organization requesting Minas Gerais state authorities to suspend the company's environmental licenses. Sigma has denied the allegations in the lawsuit, saying that its Grota do Cirilo mining project falls outside the Quilombo and the legal distance of environmental impact. Sigma Lithium shares were down 12.7% in Thursday trading. Price: 8.21, Change: -1.20, Percent Change: -12.71
