SGML · Sigma Lithium Corporation

The Company announced that a Court of Appeal Judge in the Court of Justice of Minas Gerais state overturned a lower court decision that included the potential for a legal collateral of US$10 million. The lower court ruling was originally disclosed by the Company on May 18, 2026. The appeal was successful based on robust quantitative evidence presented by Sigma Lithium, including one year of environmental monitoring data collected by third parties demonstrating low levels of dust, vibrations, and noise in four neighboring communities. The Court of Justice also requested that the Company fund an independent technical advisory firm to monitor the impacts of its operations. This legal victory removes a contingent liability and reinforces the Company's environmental compliance.
