What drove it
- Net revenues were generated from the sale of 24,400t of lithium oxide concentrate.
- Commercial flexibility improved the realized price by 17% to US$2,089 (SC5) from US$1,790 in 1Q 26.
- The reduction in costs reflected a 50% growth in production volumes to 35,400t following the continuous ramp-up of operations started in January 2026.
- The Company cited primarization of mining operations and upgrades in mining equipment as contributors to lower costs.
- Productivity improvements in the reprocessing circuit from a steady flow of spodumene delivered to the industrial plant support the FY 2027 Plant 1 production guidance.
Concerns
- Mining and plant operations have been temporarily paused since the week started July 17, 2026, pending closing of the TAC Agreement with the Minas Gerais state government.
- The partial suspension followed notification from the Vale do Jequitinhonha regional branch of the Minas Gerais state environmental agency, including fines totaling approximately US$540,000.
- The Company is evaluating financing alternatives for repayment of amounts outstanding under the export prepayment agreement with Synergy.
- Completion of the next industrial plant was pushed forward to the end of 2027, primarily to reflect the recent temporary suspension of operations.
- The Company states that lithium market prices may not remain at current levels.
What to watch
- Conclusion of the TAC Agreement and the timing of resumed mining activities.
- Continued sale of high-purity lithium fines from reprocessed tailings, which has continued without disruption.
- Ramp-up of mining haulage capacity and the next phase of equipment upgrades after mining activities resume.
- Financing negotiations for repayment of amounts outstanding under the Synergy export prepayment agreement.
- Delivery of 240,000t of lithium oxide concentrate within 12 months and 330,000 tonnes for the full year of 2027.
- Construction timing for Plants 2 and 3 and the targeted capacity expansion to 580,000tpy and 830,000tpy.
Balance sheet and cash flow
- Net debt cut to US$125 million from US$134 million at the end of 1Q 26.
- Sigma Lithium’s cash position stood at US$17 million as of June 30, 2026.
- The Company continued to receive advanced payments from the previously announced US$96 million offtake agreement.
- Amounts outstanding under the export prepayment agreement with Synergy totaled US$95 million as of June 30, 2026 (excluding $11 million cash held as collateral).
- The Company agreed to the payment of up to US$540,000 for fines.
- The Company estimates that proposed adjustments under the TAC Agreement will require estimated capex of approximately US$1,000,000.
Analysis
Sigma Lithium reported a record Q2 2026 on the measures disclosed in the release. Net revenues were US$55 million, compared with US$42 million in 1Q 26. Gross margin was 60%, compared with 61% in 1Q 26, while EBITDA margin increased to 47% from 39%. The Company also reported a 32% operating margin. Sales totaled 24,400t of lithium oxide concentrate, and the realized price increased 17% to US$2,089 (SC5) from US$1,790 in 1Q 26.
The operational ramp-up was the central cost driver. Production grew 50% to 35,400t, and the Company attributed lower costs to production growth, financial discipline, mining primarization and mining-equipment upgrades. Plant gate costs were US$ 401/t, down 36% from 1Q 26, while CIF costs were US$452/t, down 33%. Total Cash Costs of US$668/t, defined as AISC, were down 6% from 1Q 26.
Liquidity and debt reduction remain important. Net debt was US$125 million, down from US$134 million at the end of 1Q 26, and cash was US$17 million as of June 30, 2026. The Company continued receiving advanced payments under its previously announced US$96 million offtake agreement. Amounts outstanding under the Synergy export prepayment agreement totaled US$95 million as of June 30, 2026, excluding $11 million of cash held as collateral, and the Company is pursuing financing alternatives to enable a pre-payment.
The near-term operating outlook is constrained by the temporary partial suspension that began in the week started July 17, 2026. Mining and plant operations are paused while the Company negotiates a TAC Agreement with Minas Gerais state authorities, though sales of high-purity lithium fines from reprocessed tailings have continued. The Company agreed to payment of up to US$540,000 in fines and estimates approximately US$1,000,000 of capex for proposed procedural adjustments. The suspension led the Company to move its twelve-month 240,000t production guidance forward by a quarter and push completion of the next industrial plant to the end of 2027.
The longer-term production plan remains expansive. Sigma Lithium guides to 330,000 tonnes for full-year 2027 assuming Plant 1 operates throughout the year, with Plants 1 and 2 targeted for 580,000 tonnes and Plants 1, 2 and 3 targeted for 830,000 tonnes. The guidance table holds CIF China Cash Cost at ($452) across all periods and projects All-In Sustaining Cost declining from ($668) to ($620) and ($610) as additional plants are included. The immediate focus is the TAC conclusion, operational restart, financing for the Synergy balance and execution against the revised capacity timetable.
