2026-06-09SEC Filing 6-K (0001292814-26-003377)

Sigma Lithium Corporation announced a significant legal victory as a Court of Appeal Judge in the Court of Justice of Minas Gerais state overturned a prior lower court decision that had imposed a potential legal collateral of US$10 million. The appellate court's ruling was based on substantial evidence presented by Sigma Lithium, including a year's worth of environmental data collected by independent third parties. This data demonstrated the company's strong environmental track record, showing low levels of dust, vibrations, and noise in neighboring communities. The court accepted the company's data-backed defense, refuting the claims made by the local prosecution. Sigma Lithium welcomed the requirement for an independent impact assessment study as an opportunity to establish facts. The company highlighted its environmental performance, noting that its operations are significantly better than recommended standards for suspended particles and that noise and vibration levels are well within Brazilian standards. Sigma Lithium is a major producer of lithium oxide concentrate in the Americas and is committed to sustainable production for the global battery market.
