Sigma Lithium prices $125 million convertible bond, upsized 25% and fixes interest rate at 7%

Sigma Lithium Corporation priced a US$125 million, 5‑year convertible bond due November 2031, increasing the size by 25% from the originally announced US$100 million. The bond carries a fixed 7.00% coupon, replacing the prior 11.45% floating rate on its senior secured debt with Synergy Capital. Proceeds will be used to repay the US$125 million senior secured loan, cut short‑term debt by roughly 80%, and provide additional financing for growth and general corporate purposes. The conversion price is US$6.51, a 25% premium to the Nasdaq closing price of US$5.21 on 2 Nov 2026.

The fixed‑rate financing lowers Sigma Lithium’s cash interest expense and extends debt maturity to 2031, improving liquidity. Repaying the secured loan reduces short‑term liabilities by about 80%, which may enhance the company’s credit profile and give investors greater confidence in its balance‑sheet strength.
