This filing is highly significant as Sigma Lithium has secured a US$100 million collateralized bank guarantee, a crucial step towards funding the construction of its second Greentech industrial plant. This expansion is projected to nearly double the company's annual lithium oxide concentrate production capacity from 270,000 tonnes to 520,000 tonnes. The guarantee is fully collateralized by its clients, demonstrating strong customer confidence and mitigating direct financial risk to Sigma Lithium. This financing is particularly impactful given the recent 40-F filing on March 30, 2026, which disclosed an adverse auditor opinion on internal controls and significant doubt about the company's ability to continue as a going concern. Securing this substantial capital infusion provides a vital lifeline and enables the company to pursue its growth strategy despite these financial challenges, potentially alleviating immediate concerns about its operational runway and future viability.
