Sigma Lithium Corporation's stock (NASDAQ: SGML) experienced a significant increase on Monday due to the company's announcement of recommencing the sales of its primary product after remobilizing its mine operations. This led to total net sales of approximately $67 million in the fourth quarter of FY25 and first quarter of FY26. The surge in stock value was driven by the sale of about 650,000 tonnes of high-purity lithium fines and roughly 5,000 tonnes of high-grade premium lithium oxide concentrate. However, the Q4 and FY earnings report showed an EPS loss of 22 cents, falling short of the predicted five cents. Additionally, the sales of $16.903 million were below the estimated $45.678 million.
