Sigma Lithium Generates $31M in Q4 Cash From Strong Operations
Sigma Lithium demonstrated significant financial discipline in its full-year 2025 results, reporting US$31 million in cash from operations for the fourth quarter. The performance was supported by a high operating cash margin of 47%, achieved through cost optimization measures that included restructuring its mining operations. This strong cash generation enabled the company to aggressively deleverage its balance sheet, cutting total debt by 35% during 2025. The company finished Q4 2025 with cash and equivalents of US$6.2 million, even after substantial debt repayments.
Offtake Agreements Worth $146M Lock In Future Revenue
On March 30, 2026, the company announced it had secured two major offtake agreements valued at a combined US$146 million, significantly de-risking future sales. The first deal provides a US$96 million prepayment for 70,500 tonnes of high-grade lithium oxide concentrate to be delivered during 2026. A second agreement locks in the supply of 40,000 tonnes per year for three years, starting in 2026, for a US$50 million prepayment. These contracts underpin the company's working capital and provide revenue certainty, with expected cash inflows of US$35 million in Q1 2026 and US$96 million in Q2 2026.
Company Guides for 240,000 Tonnes at $592/Tonne Cost
Looking ahead, Sigma Lithium expects to produce 240,000 tonnes of high-grade premium lithium oxide concentrate over the next twelve months. Management provided an all-in sustaining cost (AISC) estimate of US$592 per tonne, a key metric that highlights its cost-efficient production capabilities. This strong operational guidance and secured cash flow position Sigma favorably within the lithium sector, which has seen mixed performance from other producers. By controlling costs and locking in future sales, the company is well-positioned to capitalize on growing demand for lithium driven by the energy storage and electric vehicle markets.
