Sigma Lithium (SGML) tops Q2 2026 guidance and outlines multi-phase growth plan
Rhea-AI Filing Summary
Sigma Lithium Corporation reported that it produced 35,000 tonnes of high-grade lithium concentrate in the second quarter of 2026, exceeding its prior guidance of 33,000 tonnes by 6%.
The company attributes this performance to a comprehensive upgrade and “primarization” of its mining operations, which improved efficiency and reliability. Its Cleantech Industrial Plant achieved 70% lithium recovery from spodumene ore and an approximate 20% yield. Sigma Lithium remains on track for annualized Phase 1 production of 240,000 tonnes and is planning Phase 2 and Phase 3 expansions toward 520,000 and 770,000 tonnes per year, respectively.
A cost and cash flow scenario table shows all-in sustaining costs as low as US$610 per tonne for all three phases combined, and illustrative annual cash flows ranging from US$130 million to US$1.135 billion at realized prices between US$1,500 and US$2,500 per tonne.

Insights
Sigma Lithium beat Q2 production guidance and outlined scaled cost and cash flow scenarios.
Sigma Lithium produced 35,000 tonnes of concentrate in Q2 2026 versus 33,000-tonne guidance, reflecting successful mining upgrades and full run-rate from its expanded fleet. The Cleantech Industrial Plant’s 70% recovery and roughly 20% yield support this operating performance.
The company targets annualized Phase 1 production of 240,000 tonnes and outlines plans to expand capacity to 520,000 and 770,000 tonnes in Phases 2 and 3. A cost table indicates all-in sustaining costs from US$710/t at 240,000 tonnes down to US$610/t at 770,000 tonnes, excluding environmental, social and financial expenses.
Scenario cash flow forecasts range from US$130M to US$1.135B annually at realized prices between US$1,500/t and US$2,500/t, illustrating leverage to lithium pricing. Actual outcomes depend on achieving planned expansions, maintaining costs, and realized market prices, with fuller detail expected in the Q2 2026 financial results scheduled for August 14, 2026.

SIGMA LITHIUM PRODUCED 35,000T LITHIUM CONCENTRATE IN 2Q26, BEAT GUIDANCE, DELIVERING SUCCESSFUL MINING OPERATIONS UPGRADE
HIGHLIGHTS
| · | Produced of 35,000t of lithium oxide concentrate in 2Q26, exceeding previous guidance of 33,000t |
| · | Demonstrates successful execution of the Company’s mining operations upgrade |
| · | Cleantech industrial operations continue to exceed expectations, achieving 70% recovery of lithium from spodumene ore, delivering approximately 20% yield |
· On track to deliver annualized production of 240,000t for Phase 1
Toronto, July 9, 2026 – Sigma Lithium Corporation (NASDAQ: SGML, TSX-V:SGML BVMF: S2GM34) (“Sigma Lithium” or the “Company”), the largest producer of lithium oxide concentrate in the Americas¹ and dedicated to industrializing sustainable and traceable lithium materials to supply global producers of batteries for energy security, announces that it exceeded by 6% its production guidance for the second quarter of 2026, delivering 35,000 tonnes of high grade lithium concentrate, compared with the previous guidance of 33,000 tonnes.
The production performance was a result of the successful execution by Sigma Lithium of a comprehensive mining upgrade, following a primarization of its mining operations. The Company’s Cleantech Industrial Plant continued to exceed expectations, achieving 70% recovery of lithium from spodumene ore and delivering an approximate 20% yield. During the quarter, the Company reached full operating run-rate from its expanded mining fleet, supported by an optimized mine plan and enhanced operational execution. The upgrade to the mining operations improves operating efficiency and strengthens production reliability, providing greater operational flexibility.
As a result of the primarization, Sigma Lithium’s own mining operations team demonstrated its readiness to deliver the raw materials to support the Company’s industrial growth plans to build a second Cleantech Industrial Plant within 12 months and potentially a third Cleantech Industrial Plant, as indicated in Table 1 below.
