Sigma Lithium Business Summary

Sigma Lithium Corp (SGML) is a leading commercial producer of high-purity, environmentally sustainable lithium concentrate, primarily generating revenue through the sale of its proprietary "Quintuple Zero Green Lithium" from its 100%-owned Grota do Cirilo project in Brazil. The company operates as a pure-play lithium miner, with primary business segments focused on the extraction and industrial processing of spodumene ore into battery-grade concentrate. As of early 2026, Sigma has successfully diversified its revenue streams by monetizing high-purity lithium fines (tailings), transforming former waste into a significant secondary product line. The company is currently executing a phased expansion to increase its nameplate capacity from 270,000 tonnes per year to 520,000 tonnes by the end of 2026. Sigma competes directly with major hard-rock producers such as Pilbara Minerals, Liontown Resources, and Core Lithium, distinguishing itself in the market through a low-cost production profile and a verified net-zero carbon footprint. The company was co-founded by Ana Cabral and Marcelo Paiva through the investment firm A10 Invest, which remains the company's largest shareholder. The current leadership team is led by CEO and Co-Chairperson Ana Cabral, a former senior investment banker at Goldman Sachs with over 20 years of experience in global capital markets. Key executives include Felipe Peres, who serves as the sole Chief Financial Officer following a 2025 leadership consolidation, and Anna Hartley, the Head of Investor and Global Banking Relations. The Board of Directors features prominent figures such as Co-Chairperson Marcelo Paiva and recently appointed independent director Katia Abreu, a former Brazilian Minister of Agriculture. Notable institutional backing includes major positions from BlackRock, Van Eck Associates, and State Street Corp, reflecting strong investor confidence in Sigma's operational scaling and ESG-centric business model.
