Sigma Lithium Reports Strong 32% Operating Margin and Extends Debt Maturities
Key Facts
The update distinguishes preliminary indicators from results that have not yet been reported, contrary to the previous draft’s claim that the company achieved a 32% gross margin in the third quarter. That figure refers to the operating margin in the second quarter, when the company also reported a 60% gross margin and a 47% EBITDA margin. The company said that quarter’s EBITDA margin was the highest in its history, compared with 39% in the first quarter. Second-quarter performance provides a basis for comparison with the anticipated figures, while the third-quarter picture remains tied to the report scheduled for release in November.
In the second quarter, the company generated net revenue of $55 million from the sale of 24,400 tonnes of lithium oxide concentrate. The realized price rose to $2,089 per tonne, up 17% from $1,790 in the first quarter. CIF cost was $452 per tonne, down 33% from the previous quarter, while AISC reached $668 per tonne, down 6%. These earlier figures provide context for the costs and prices the company said it would report in its third-quarter results.
On financing, the company said in a separate filing that it extended the maturity of $100 million in secured debt to June 2027, and said the maturities of more than 90% of its debt had been extended. The company described the extension as giving it time to continue increasing production and building operating cash flow before the new maturity date. Available materials did not establish that the Hong Kong convertible bond issuance was conducted in partnership with Synergy Capital, or that its purpose was to reduce financing costs; accordingly, the company does not link the issuance to those claims. The company said it had repaid more than $90 million of debt since the second quarter of 2024 through cash generation. It also reduced total debt by about 40% over two years to $125 million on October 21, 2026, while net debt was $125 million at the end of June, compared with $134 million at the end of March, and cash stood at $17 million on June 30.
Sigma Lithium resumed operations on October 5 after a Federal Supreme Court decision reinstated its environmental licenses, according to the company. It produced 7,090 tonnes of lithium oxide concentrate between October 5 and 21, according to its debt extension filing. The resumption followed a shutdown linked to the dispute over the licenses, making the pace of production after the restart part of the monitoring of third-quarter results. In the first half of 2026, the company recorded operating cash flow of $27.2 million, compared with cash used of $8.2 million in the same period of 2025. This shift in cash flow provides context for the company’s reference to building operating cash flow, but by itself does not determine the trajectory of cash flows after production resumed.
The company set a target of increasing annual production to 330,000 tonnes by the end of 2027. It said its industrial clean-technology plant had previously demonstrated the ability to produce more than 950 tonnes per day following a technical upgrade in the fourth quarter of 2024. The target comes alongside the debt maturity extension and the resumption of operations, while the company said the time until the new maturity would allow it to increase production and build cash flow. Investors’ next focus is the report expected by November 13, which will cover third-quarter production, sales, realized prices, costs and cash. The company’s shares, listed under the ticker SGML, closed at $7 on October 30, according to EL7 data.
