Sigma Lithium Announces Full Year 2025 Results: US$31M Cash Flow and 47% Cash Margin in 4Q25; Signed US$146M in Two Offtake Agreements

Sigma Lithium Corporation reported robust financial performance for 2025, highlighted by strong cash generation of US$31 million from operations in the fourth quarter and an impressive 47% operating cash margin. The company achieved net sales revenues of approximately US$67 million in Q4 2025 and Q1 2026, primarily from sales of 650,000 tonnes of high-purity lithium fines and 5,000 tonnes of high-grade premium lithium oxide concentrate. This marked a successful restart of sales following the remobilization of mining operations after a strategic restructuring period.

The company significantly strengthened its financial position by securing US$146 million in offtake agreements, comprising a US$96 million prepayment for 70,500 tonnes to be delivered in 2026 and a US$50 million agreement for 40,000 tonnes per year over three years starting in 2026. These agreements provide crucial working capital support and include flexible delivery timing to optimize market positioning. Concurrently, Sigma Lithium executed an aggressive deleveraging strategy, reducing trade finance debt by 60% and total debt by 35% during 2025.

Operationally, the company demonstrated strong cost discipline with a 77% year-over-year reduction in operating costs, more than offsetting a 64% decline in net sales revenues. The successful transition from external contractors to operational control achieved significant efficiency gains and cost optimization. Looking forward, Sigma Lithium projects production of 240,000 tonnes of high-grade premium lithium oxide concentrate over the next twelve months at an all-in sustaining cost of US$592 per tonne, with expansion plans targeting 520,000 tonnes by 2027.

The results underscore Sigma Lithium's position as the largest lithium oxide concentrate producer in the Americas, operating what it claims is the world's fifth-largest industrial-mineral complex for lithium oxide concentrate. With expected cash inflows of US$96 million in Q2 2026 and a strengthened balance sheet, the company appears well-positioned to capitalize on lithium market opportunities while maintaining its focus on environmentally sustainable production practices at its Grota do Cirilo operation in Brazil.
