São Paulo, Brazil–(Newsfile Corp. – February 13, 2026) – Sigma Lithium Corporation (TSXV: SGML) (NASDAQ: SGML) (BVMF: S2GM34) (“Sigma Lithium” or “the Company”), a leading global lithium producer dedicated to powering the next generation of electric batteries with socially and environmentally sustainable lithium concentrate, announces the sale of 150,000 tonnes of high purity lithium fines with 1% of lithium oxide content (“Low Grade Product”) at a net final price of US$140/t.
The same agreement gives the buyer an option to purchase an additional 350,000 tonnes of the Low Grade Product at market prices upon warehouse delivery at the port of Vitoria. The volume optionality ensures the flexibility to respond to robust market conditions for the Low Grade Product and customer requirements across the Company’s portfolio.
The commercial success of Sigma Lithium’s Low Grade Product can potentially generate the equivalent proceeds of sales of 70,000 tonnes of Sigma Lithium’s high-grade lithium oxide concentrate (“High Grade Lithium Concentrate”).
The sale of the Low Grade Product is the “sustainability reward” for the shareholders of the Company: the successful commercialization is made possible by the quality of the Low Grade Product, which is industrialized using the innovative lithium dense media separation technology of Sigma Lithium’s Greentech Plant that preserves the chemical integrity of the lithium crystal structure.
As a result of the superior quality of the Low Grade Product, Sigma Lithium’s clients achieved up to 60% recovery in re-processing, obtaining lithium concentrate with over 4% lithium oxide content (priced at approximately US$1,370/t currently on average by Shanghai Metals Market).
PRODUCTION-BACKED REVOLVER
The resumption of production cadence of the High Grade Lithium Concentrate triggers the commencement of pre-payments under the revolver facility of US$96 million, strengthening Sigma Lithium’s near-term liquidity.
The unsecured binding agreement signed with a leading company in the battery materials supply chain, provides for the supply of 70,500 tonnes of High Grade Lithium Concentrate by Sigma Lithium during 2026. Under the terms, each prepayment’s fixed installment of US$8 million occurs 30 days prior to production and delivery to the Port of Vitoria of an agreed upon quantity. The first prepayment was disbursed, as previously announced, on January 13th. . Each prepayment carries an interest of SOFR +1% for 30 days until final sale upon delivery to the Port of Vitoria.
The pricing of each sale is determined to match the prevailing spot market price for High Grade Lithium Concentrate, as per the major indexes, preserving full exposure to price upside and demonstrating a disciplined sales approach as lithium market fundamentals continue to improve.
Sigma Lithium’s VP of Commercial Catarina Noci said: “This production-backed revolving agreement reflects our client’s confidence in Sigma Lithium’s ability to deliver consistent High Grade Lithium Concentrate volumes at scale. It builds on a relationship that has developed steadily over time and underscores our role in the lithium supply chain. It follows more than a year of commercial collaboration through our trading partners, during which we have supplied High Grade Lithium Concentrate to support the client’s businesses. It speaks to the reliability and quality of our product, as well as to the strength of the partnership we have established.
Sigma Lithium’s VP of Business Development Marina Bernardini said: “Our sequential sales of the Low Grade Product show how this material can generate recurring value, demonstrating its marketability. Continuous demand for the Low Grade Product has supported the creation of an additional revenue stream for the Company. This opportunity stems from both our large existing inventory of Low Grade Product available for reprocessing and the ongoing annual generation of approximately 300,000 tonnes of this material through our Greentech Plant’s dry stacking technology. Our sustainability-centered relationships are mutually beneficial, as our clients generate additional value by concentrating our Low Grade Product into higher grade lithium material”.
