Sigma Lithium posts US$31M 4Q25 cash flow and secures US$146M offtakes
Sigma Lithium generated US$31M cash from operations in 4Q25 with a 47% operating cash margin and reported US$35M inflows in 1Q26 alongside expected US$96M in 2Q26. It secured US$146M in prepayments through two offtake deals supplying 70,500 tonnes in 2026 and 40,000 tonnes annually over three years.
1. Strong Cash Generation
Sigma Lithium generated US$31 million in cash from operations in 4Q25, comprising US$41 million inflows less US$10 million in operating costs, and ended the quarter with US$6.2 million in cash. In 1Q26 it reported US$35 million in inflows and anticipates US$96 million in 2Q26, largely backed by offtake prepayments.
2. Significant Offtake Agreements
The company secured two prepayment-based offtake agreements totaling US$146 million: US$96 million for delivery of 70,500 tonnes of lithium oxide concentrate during 2026 and US$50 million for 40,000 tonnes per year over three years beginning in 2026. Flexible delivery schedules are designed to support working capital and leverage market seasonality.
3. Commercial Sales and Mine Remobilization
Net sales revenues reached approximately US$67 million in 4Q25 and 1Q26, driven by sales of about 650,000 tonnes of high-purity lithium fines and 5,000 tonnes of high-grade concentrate. These shipments followed the remobilization of mine operations in January 2026 after an October 2025 restructuring.
4. Deleveraging and Production Guidance
In 2025 Sigma Lithium cut trade finance debt by 60% and total debt by 35% to US$141 million, with a further 21% reduction in trade finance debt to US$19 million by 1Q26. The company forecasts producing 240,000 tonnes of concentrate over the next 12 months at an all-in sustaining cost of US$592 per tonne, with higher lithium prices driving additional cash flow upside.
