Sigma Lithium Announces Record Results for 1Q26: 39% EBITDA Margin; 26% Profitability; 21% of Total Debt Repaid

Sigma Lithium Corporation delivered exceptional first quarter 2026 results, achieving the highest profitability margins in the company's history. The lithium producer posted a 61% gross margin, 39% EBITDA margin, and 26% net margin, representing a significant improvement from previous quarters. Revenue generation reached $42 million from the sale of 23,000 tonnes of lithium oxide concentrate equivalent, with a realized price of $1,790 per tonne for high-grade concentrate (SC5 basis), a substantial increase from $630 per tonne in Q3 2025.

The company's financial position strengthened considerably during the quarter, with total debt declining 21% year-over-year and 33% over two years to $134 million. This deleveraging was achieved through strategic repayment of higher-cost short-term export financing lines, which fell from $102 million to $13 million. Cash position improved to $28 million as of May 15, 2026, the highest level since year-end 2024, supported by strong collections of accounts receivable and advance payments from offtake agreements.

Operationally, Sigma Lithium successfully completed the ramp-up of mining operations following a restructuring that began in October 2025. The company is on track to achieve its production guidance of 240,000 tonnes per year of high-grade lithium oxide concentrate. Management remains committed to aggressive expansion plans, with Phase 2 expected to increase capacity to 520,000 tonnes and Phase 3 to 770,000 tonnes, both targeted for completion by year-end 2027.

The results demonstrate Sigma Lithium's operational excellence and market positioning as the largest lithium oxide concentrate producer in the Americas. The company's Grota do Cirilo operation in Brazil represents the fifth-largest industrial-mineral complex for lithium oxide concentrate globally. With improved lithium pricing, operational efficiency gains, and a strengthened balance sheet, Sigma Lithium appears well-positioned to capitalize on growing demand for battery materials while maintaining its focus on environmental and social sustainability.
