## Key facts

- Facility principal: US$100 million
- Revised maturity: June 2027
- Interest rate: SOFR + 6.95% per year
- Restart-period output: 7,090 tonnes through 21 October

Sigma Lithium said on 23 October that it had signed an agreement to extend the maturity of its US$100 million senior secured debt with Synergy Capital by six months, from December 2026 to June 2027. The company said the facility’s interest rate remained SOFR plus 6.95% a year, with covenants and events of default similar to the original agreement. The extension changes the repayment date; the announcement did not describe a new borrowing or an increase in principal.

Sigma said the extension defers its final repayment requirement and lengthens 93% of its debt profile to June 2027. It reported total debt of US$125 million as of 21 October, down about 40% over two years, and said it had repaid more than US$90 million since the second quarter of 2024 through cash generation. These are company-reported figures; the release did not include a balance sheet reconciliation or audited financial statements for the period ending 21 October.

The financing update comes shortly after a temporary suspension and restart at the company’s Grota do Cirilo lithium operation in Minas Gerais, Brazil. Sigma reported that operations resumed on 5 October following a Federal Court of Appeals decision reinstating its environmental licences. The company’s 23 October release said it produced 7,090 tonnes of lithium oxide concentrate between 5 and 21 October. Its earlier 6 October announcement described the restart and maintained a target of 330,000 tonnes of annualized concentrate production by year-end 2027, relying on existing mine and processing capacity. That target remains forward-looking and is not the output rate reported for October.

The current release says Sigma expects the extended repayment schedule to give it more time to ramp production and build operating cash flow before the new maturity date. It did not publish a quantified cash-flow forecast or revised debt-service schedule. The company said it plans to report third-quarter 2026 production, sales, realized prices, costs and cash by 13 November. The 7,090-tonne restart-period production figure is therefore a company update for a short interval, rather than the company’s full third-quarter results.

The loan originated in 2022 as a senior secured pre-export financing agreement with Synergy Capital, which Sigma’s original announcement identified as a current shareholder based in the United Arab Emirates. That announcement described a multi-draw facility of up to US$100 million, with a four-year maturity and interest at the 12-month Bloomberg Short-Term Bank Yield Index plus 6.95%. The 2026 announcement identifies the original scheduled maturity as December 2026 and the revised date as June 2027, while stating that the rate remains unchanged. The 2022 agreement therefore provides background on the facility’s initial structure; the October extension terms are taken from the current company announcement. Synergy’s current website names Synergy Management (DIFC) Limited as its investment manager and says it is regulated by the Dubai Financial Services Authority. The financing counterpart provides the UAE connection in this story; the lithium operation itself is in Brazil.

The company’s announcement describes the extension as supporting operational ramp-up after the court decision, but does not establish that the new maturity alone will secure the production target or improve realized lithium prices. It also does not disclose Synergy’s rationale or any conditions beyond maintaining similar covenants and default terms. The next stated operational disclosure is the planned third-quarter report in November.
