New Projects/Investments

Brazil's National Mining Agency (ANM) issued an official technical statement on February 2, 2026, explicitly attesting to the safety of Sigma Lithium's waste piles.

Sigma Lithium's management maintains that an administrative enquiry opened by the Brazilian Ministry of Labor and Employment in December 2025 regarding health and safety has no material effect on the Company's capacity to continue mining activities.

Guidance Update

Sigma Lithium has resumed mining activities at its Mine 1 in Vale do Jequitinhonha, Brazil, as scheduled, following a restructuring of operations.
The restructuring, which aimed to increase safety and operating efficiency, was partly financed by the commercial success of high-purity low-grade lithium oxide concentrate fines.
The new operational structure is expected to support a planned increase in production scale within the next 12 months, including the resumption of construction and commissioning of the Phase 2 Greentech Industrial Plant.
The company provided illustrative annual guidance for cash flow generation under various production and price scenarios, demonstrating its low costs and operational resilience.
