São Paulo, Brazil--(Newsfile Corp. - May 15, 2026) - Sigma Lithium Corporation (NASDAQ: SGML) (TSXV: SGML) (BVMF: S2GM34) ("Sigma Lithium" or the "Company"), the largest producer of lithium oxide concentrate in the Americas1 and dedicated to industrializing socially and environmentally sustainable lithium materials to supply global producers of batteries for energy security, announces the Company's results for the three months ended March 31, 2026 and provides an update on recent developments.
POSTED RECORD MARGINS
In 1Q26, Sigma Lithium achieved the highest profitability in the Company's history, posting record margins, with gross margin of 61%, EBITDA margin of 39% and net margin of 26%. The Company delivered solid sales volumes, maintained its low cost position and benefited from higher lithium prices. Sales volume in 1Q26 was 23,000 tonnes of both low grade and high grade lithium oxide concentrate, calculated on an equivalent basis for 5% Li2O content. The realized price for high-grade lithium oxide in 1Q26 was US$1,790 per tonne SC5 (US$2,150 SC6), which compares with 3Q25, the last quarter before the Company's restructuring of mining operations, with US$630 per tonne SC5 (US$756 SC6).
STRONG REVENUE GENERATION
In 1Q26, Sigma Lithium generated solid revenues of US$42 million, up 150% from 4Q25, when sales were impacted by the above mentioned mining restructuring, and represent the highest quarterly revenues achieved by the Company since 1Q25 (US$48 million). Revenue generation in 1Q26 was achieved almost exclusively through the sales of lithium oxide concentrate of different grades, with only a small about of shipping service revenues. This compares with 4Q25, when revenue was made up primarily of positive adjustments on provisionally priced sales and a substantial amount in shipping service revenue.
CONTINUED TO DELEVERAGE
In 1Q26, Sigma Lithium continued to reduce debt. Total debt at the end of 1Q26 stood at US$134 million, having declined by 21% in one year and by 33% in two years. The reduction was achieved despite lithium market volatility and via a strategy of progressively paying down higher cost short term export financing lines, which fell from a two-year high at the end of 2Q24 at US$102 million to US$13 million at the end of 1Q26.
SIGNIFICANT INCREASE IN CASH POSITION
Today, May 15, 2026, Sigma Lithium's position in cash and equivalents is US$28 million, which is the largest amount the Company has recorded since year end 2024. Sigma Lithium ended 1Q26 with US$4 million in cash and equivalents, but the strong sales in the quarter resulted in an accounts receivable balance of US$22 million, which has since been mostly translated into the Company's cash balances. The Company also continued to receive advanced payments for sales of high-grade lithium oxide concentrate, including from the previously announced US$96 million working capital offtake agreement, as well as from the sales of high purity low grade materials.
ON TRACK TO DELIVER PRODUCTION OF 240,000t
Sigma Lithium successfully concluded a full ramp up of mining operations following the restructuring started in October 2025 and is on track to achieve the production guidance provided at the end of 1Q26 of an annualized 240,000 tonnes per year of high-grade lithium oxide concentrate.
Sigma Lithium remains committed to deliver high near-term growth and now expects the next two phases of the Company's development to be concluded by year end 2027. These are the expansions Phase 2, designed to take nominal annual capacity from the current 270,000 tonnes of high-grade lithium oxide concentrate to 520,000 tonnes, and Phase 3, designed to lift annual capacity further to 770,000 tonnes.
Sigma Lithium adjusted the guidance previously provided for costs per tonne to reflect higher diesel prices and an appreciation of the Brazilian Real against the U.S. Dollar, which are shown in the table below. The forecasts do not incorporate savings from higher efficiency in mine operations following the recent restructuring, but the Company continues to expect these to be achieved over time.
