A10 Global Fund, L.P. Continues to Raise Its Position in Sigma Lithium Corporation

A10 Global Fund, L.P., a specialized critical minerals investment vehicle, has announced continued accumulation of shares in Sigma Lithium Corporation (NASDAQ: SGML), remaining below the 5% reporting threshold. The fund, launched in June 2025 and managed by Sigma Lithium's Co-Chair Marcelo Paiva, has delivered exceptional performance with 177% annualized returns and a 1.94 Sharpe ratio.

Sigma Lithium's operational transformation has yielded impressive financial results in the first quarter of 2026, including record profitability metrics: 26% net margin, 39% EBITDA margin, and 61% gross margin. The company has successfully restructured its mining operations, expanding its hauling fleet by 40% and transitioning to an integrated team model, enabling it to remain on track for its 240,000 tonnes annual production guidance.

The investment thesis combines favorable macroeconomic trends and company-specific fundamentals. A10 Global identifies accelerated global electrification, AI-driven energy storage demand, and supply chain timing lags as key drivers supporting lithium demand that is effectively one year ahead of current utilization models. The fund believes lithium miners are supplying 2027 demand rather than 2026 demand, creating a significant market opportunity.

Sigma Lithium's financial position has strengthened considerably, with total debt falling 21% year-over-year and 33% over two years, while cash reached $28 million as of May 15, 2026. The company's expansion pipeline through Phase 2 and 3 developments targets increasing annual capacity from 270,000 to 770,000 tonnes by year-end 2027, supported by Brazil's relatively low capital intensity environment and constructive lithium pricing.
