Sigma Lithium Corporation ("Sigma Lithium" or the "Company") (NASDAQ:SGML, BVMF: S2GM34, TSXV:SGML), a leading global lithium producer dedicated to powering the next generation of electric vehicles with carbon neutral, socially and environmentally sustainable lithium concentrate, is pleased to announce it signed an inaugural deferred US$ 22.4 million letter of credit for export financing with Banco do Brasil at very low interest rates.

As Sigma matures as an industrial producer and demonstrates its ability to consistently deliver its Quintuple Zero Green Lithium, it gained access to access low-cost trade finance mechanisms through Banco do Brasil, available to the country's largest industrial exporters. These agreements enhance Sigma Lithium's commercial flexibility and market access.

As a result of the lower interest export credit lines, the Company will phase out the existing trade lines in its treasury, thus decreasing the Company's recurring interest expenses and further improving its competitiveness.
