Production Beat and Share Reaction
Sigma Lithium Corporation (NASDAQ: SGML) saw its shares rise 3.3% in after‑hours trading on Thursday after the company disclosed that second‑quarter 2026 lithium‑oxide concentrate production reached 35,000 tonnes, exceeding its prior guidance of 33,000 tonnes by 6%.
Operational Highlights
The increase reflects a comprehensive upgrade to mining operations, with the expanded mining fleet achieving full operating run‑rate under an optimized mine plan. The company’s Cleantech Industrial Plant recorded a 70% recovery rate of lithium from spodumene ore and delivered an approximate 20% overall yield during the quarter.
Phase 1 Production Target and Expansion Plans
Sigma Lithium remains on track to achieve an annualised Phase 1 production capacity of 240,000 tonnes. Following the operational upgrade, the firm indicated readiness to construct a second Cleantech Industrial Plant within the next 12 months and is evaluating the addition of a third plant.
Cost Structure and Cash‑Flow Forecast
All‑in sustaining costs are projected at $710 per tonne for Phase 1 production, decreasing to $620 per tonne when Phase 2 is online and further to $610 per tonne with all three phases operational; these figures exclude environmental, social and financial expenses. Assuming a realized lithium price of $1,500 per tonne, the company forecasts cash flow of $130 million for Phase 1 alone, rising to $327 million with Phase 2 and $493 million when all three phases are running.
Upcoming Financial Release
Sigma Lithium will publish its full second‑quarter 2026 financial and operating results on August 14, 2026.
