Sigma Lithium Resources Corp

Sigma Lithium reported record second-quarter 2026 results, with net sales revenue of $54.7 million, up 223.9% year over year, and an adjusted EBITDA margin of 47.0%, the highest in company history. Lithium oxide concentrate production reached 35,400 tonnes, a 52% increase from the first quarter, driven by the ramp-up of mining operations. The company realized a net lithium price of $2,089 per ton for SC5, a 17% sequential increase, while plant gate cost fell 36% to $401 per ton and CIF cost decreased 33% to $452 per ton. Sigma Lithium also reduced total debt by 25% over the last year and held $16.7 million in cash as of June 30, 2026, with management projecting an additional $60 million in cash inflows during the third quarter. The company maintained its Plant 1 twelve-month forward guidance of 240,000 tonnes, with the ramp-up timeline pushed forward by three months due to a temporary suspension, and raised its fiscal 2027 production guidance to 330,000 tonnes for Plant 1, exceeding nominal capacity due to improvements in the reprocessing circuit.

Sigma Lithium is generating enough cash to fully repay a $100 million debt facility by year-end, Co-Chair Marcelo Paiva said Friday in a Bloomberg interview. The loan, which accounts for the bulk of Sigma's $134 million in debt as of March 31, matures around December, four years after it was signed with the Brazilian miner's United Arab Emirates-based shareholder Synergy Capital. Paiva told Bloomberg that the company is producing and generating cash, and that the loan carries a high borrowing cost so there is no interest in renewing. Sigma's Grota do Cirilo complex is one of the world's largest hard-rock lithium deposits, and second-quarter production exceeded guidance by 6 percent despite an equipment upgrade. The company reported negative free cash flow in the first quarter but has since benefited from advance payments under lithium concentrate sales agreements, with cash reaching $28 million as of May 15, its highest level since the end of 2024.

Sigma Lithium exceeded its second-quarter production guidance by 6%, delivering 35,000 metric tons of high-grade lithium concentrate compared to its previous expectation of 33,000 tons. The company attributed the performance to the successful execution of a comprehensive mining upgrade following a primarization of its mining operations, while its Cleantech industrial plant achieved 70% recovery of lithium from spodumene ore and a roughly 20% yield. Sigma Lithium also reached a full operating run rate during the quarter from its expanded mining fleet, supported by an optimized mine plan and enhanced operational execution. The company stated that its mining operations team demonstrated readiness to supply raw materials for a second Cleantech industrial plant within 12 months and potentially a third.

Sigma Lithium Corporation announced that a Court of Appeal Judge in the Court of Justice of Minas Gerais overturned a previous lower court ruling that included a potential $10 million legal collateral requirement. The court requested that the company support the appointment of an independent technical advisory firm to assess and monitor the impact of its operations on residents in the municipalities of Aracuai and Itinga. Sigma Lithium welcomed the assessment process, stating that the independent review would provide an opportunity to establish factual information regarding operational impacts. Separately, the company reported filing one year of externally verified environmental monitoring data covering the 12 months through May 2026, which demonstrated compliance with dust, noise, and vibration standards.

Sigma Lithium Corporation shares rose 1.54% to close at $11.89, outperforming the S&P 500's 1.18% gain. The company is expected to report earnings per share of $0.15, a 188.24% increase from the same quarter last year, on revenue of $54 million, up 219.72%. For the full year, analysts forecast earnings of $1.15 per share and revenue of $342 million, representing growth of 355.56% and 210.88%, respectively. Sigma Lithium currently holds a Zacks Rank of 1, or Strong Buy, and trades at a forward price-to-earnings ratio of 10.18, a discount to the industry average of 15.98.
