Sigma Lithium narrowed its net loss to US$2.6 million in the second quarter of 2026. A big improvement on the US$18.9 million loss it booked a year earlier.
The Brazil-focused miner managed it on record revenue and the fattest margins in its short history. Yet a one-off charge still tipped the bottom line into the red.
What Sigma Lithium reported
The numbers land in an awkward but honest place. Revenue and margins set records, yet the company still finished the quarter with a small loss.
Because the loss shrank so much from last year, the direction of travel is clearly upward. But a single accounting charge kept it from turning a profit.
So the story is really two stories. One is a business getting leaner and earning more per tonne, and the other is a lingering regulatory headache at home.
A record top line
Net revenue reached US$55 million, the most the company has ever booked in a single quarter. That was up from US$42 million just three months earlier.
Higher prices did much of the heavy lifting here. The company sold 24,400 tonnes of lithium concentrate and squeezed more value out of each shipment.
Why there was still a loss
Here is the part that needs a plain explanation. The quarter carried a US$9.4 million idle-capacity charge, an accounting cost for plant capacity sitting unused.
That charge is tied to a partial suspension of some operations in Minas Gerais. Strip it out, and the underlying business was comfortably profitable.
In short, the loss reflects a temporary regulatory snag rather than a broken business. The operating engine kept running well through the quarter.
Cutting costs hard
Costs are where management clearly pushed. The plant-gate cost, the price of getting rock ready at the mine, fell 36% to US$401 per tonne.
The broader all-in sustaining cost, which folds in shipping and other outlays, came in at US$668 per tonne. The company set that figure as its full-year target.
Lower costs matter enormously in this business. When lithium prices swing wildly, the cheapest producers are the ones left standing.
Selling for more per tonne
The realized price rose 17% to US$2,089 per tonne of concentrate, up from US$1,790 in the previous quarter. Smarter timing of sales helped lift that figure.
For a company still climbing out of a brutal price downturn, every extra dollar per tonne counts. Better prices and lower costs widened the gap between the two.
More rock out of the ground
Production climbed 52% from the first quarter to 35,400 tonnes of lithium concentrate. That beat the company’s own guidance for the period.
It sold 24,400 tonnes of that output. The rest builds inventory it can ship into stronger markets later, when prices allow.
The margin story
Adjusted earnings before interest, tax and other items reached US$25.7 million. That translated into a 47% margin, the highest the company has recorded.
For comparison, the same margin was 39% in the first quarter. Its gross margin, meanwhile, widened to 60%, a sign that pricing and cost discipline both worked.
The dispute behind the charge
The idle-capacity charge traces back to an environmental matter in the state of Minas Gerais. Sigma is negotiating a settlement known in Brazil as a TAC agreement.
A TAC is a standard deal between a company and regulators to adjust procedures and resolve complaints. It is a common, workable path, not a shutdown order.
The company expects to pay up to US$540,000 in fines and spend roughly US$1 million to bring the affected operations fully back online.
Where the lithium comes from
Sigma mines in the Vale do Jequitinhonha, a valley in Minas Gerais long known for its mineral wealth. Its Grota do Cirilo project sits at the heart of the operation.
It markets its output as low-carbon, green spodumene, aimed at buyers who want cleaner supply chains. That pitch has helped it win customers in a crowded market.
The expansion plan
The company is not standing still. Its current plant can produce about 270,000 tonnes of concentrate a year, and it wants to build well beyond that.
A planned second phase would lift capacity to roughly 520,000 tonnes a year. A later third phase targets around 770,000 tonnes, nearly triple today’s level.
Those expansions depend on prices holding up and financing falling into place. For now, the priority is proving the current plant can run cheaply and steadily.
What to watch next
The big question is whether Sigma Lithium can clear the Minas Gerais dispute and switch that idle capacity back on. Doing so would remove the drag on profit.
Investors will also watch lithium prices, which remain far below their frenzied 2022 peak. A firmer market would reward the company’s low costs quickly.
For Brazil, a healthy Sigma matters beyond one balance sheet. It is a test of whether the country can turn its lithium into a durable export industry.

How much did production and prices change?
Production rose 52% from the prior quarter to 35,400 tonnes. And the realized price climbed 17% to US$2,089 per tonne of lithium concentrate.
What are Sigma Lithium’s expansion plans?
It aims to lift annual capacity from about 270,000 tonnes toward 520,000 in a second phase. And roughly 770,000 tonnes in a later third phase.
