#Sigma Lithium Reports Record Q1 2026 Results
Sigma Lithium Corporation (NASDAQ: SGML) (TSXV: SGML) (BVMF: S2GM34) reported first-quarter 2026 results showing the highest profitability in the company's history, with a 61% gross margin, 39% EBITDA margin and 26% net margin. The Brazil-based lithium oxide concentrate producer also reduced total debt by 21% year-over-year to US$134 million.
The margin improvement followed a restructuring of mining operations that began in October 2025 and a recovery in realized prices. Sigma Lithium reported a realized price of US$1,790 per tonne SC5 (US$2,150 SC6) in the quarter, compared with US$630 per tonne SC5 (US$756 SC6) in the third quarter of 2025, the last quarter before the mining restructuring.
#Sigma Lithium Generates US$42 Million in Quarterly Revenue
Revenue for the quarter totaled US$42 million, up 150% from the fourth quarter of 2025, when sales were affected by the mining restructuring. The company said 1Q26 revenue represented the highest quarterly total since 1Q25, when revenue reached US$48 million.
Sales volume in the quarter was 23,000 tonnes of low-grade and high-grade lithium oxide concentrate, calculated on an equivalent basis for 5% Li2O content. Revenue was generated almost exclusively from concentrate sales, with only a small contribution from shipping service revenue.
Gross profit rose to US$26 million from US$13 million in 1Q25, while net income increased to US$11 million from US$5 million. Cost of sales fell to US$16 million from US$35 million a year earlier.
#Sigma Lithium Cuts Total Debt by 21% Over One Year
Total debt at the end of 1Q26 stood at US$134 million, down 21% from a year earlier and 33% from two years ago. The company said the reduction was achieved by progressively repaying higher-cost short-term export financing lines, which fell to US$13 million at the end of 1Q26 from a two-year high of US$102 million at the end of 2Q24.
"Sigma Lithium continued to reduce debt," the company said in its earnings release, noting that the deleveraging occurred against a backdrop of lithium market volatility.
Cash and equivalents stood at US$28 million as of May 15, 2026, the highest level since year-end 2024. Sigma Lithium ended the quarter with US$4 million in cash and US$22 million in accounts receivable, most of which the company said has since converted to cash. The balance also reflects advanced payments under a previously announced US$96 million working capital offtake agreement.
#Production Tracking to 240,000 Tonnes Annualized
Sigma Lithium said it has completed the ramp-up of mining operations following the restructuring and remains on track to deliver annualized production of 240,000 tonnes of high-grade lithium oxide concentrate. Nameplate capacity at the Grota do Cirilo operation in Brazil is 270,000 tonnes per year, equivalent to approximately 38,000 to 40,000 tonnes of lithium carbonate equivalent.
The company adjusted its cost-per-tonne guidance to reflect higher diesel prices and an appreciation of the Brazilian Real against the US Dollar. CIF China cash cost for the 12-month Phase 1 period is now estimated at US$624 per tonne, with an all-in sustaining cost of US$710 per tonne. The forecasts do not incorporate efficiency gains the company expects to realize over time from the mining restructuring.
Sigma Lithium operates in the hard-rock lithium concentrate segment alongside producers including Pilbara Minerals, Albemarle’s spodumene operations, and the Greenbushes joint venture operated by Talison Lithium and owned by Tianqi Lithium, IGO, and Albemarle. The lithium concentrate market has been characterized by price volatility over the past two years as supply additions met variable demand from battery cathode manufacturers.
#Expansion Phases Targeted for Year-End 2027
Sigma Lithium said it now expects to complete its Phase 2 and Phase 3 expansions by year-end 2027. Phase 2 is designed to lift nominal capacity to 520,000 tonnes from the current 270,000 tonnes, and Phase 3 is designed to take capacity to 770,000 tonnes. Industrial Plant 2 is fully funded, while Industrial Plant 3 remains unfunded.
The company's forward outlook is subject to lithium price volatility, execution risk on the Phase 2 and Phase 3 expansions, foreign exchange movements between the Brazilian Real and the US Dollar, and the pace at which the electric vehicle battery market develops. Sigma Lithium stated in its release that there can be no assurance lithium market prices will remain at current levels.
