Investing.com – Sigma Lithium Corporation (NASDAQ:SGML) (TSXV:SGML) (BVMF:S2GM34) shares rose 3% on Thursday after the company announced it has signed a $100 million secured bank guarantee agreement with a major Brazilian bank.

The bank guarantee will be fully secured through a combination of corporate guarantees, letters of credit, and export receivables provided by the company’s customers. The financing will support the construction of Sigma Lithium’s second green-tech industrial plant, which will double the company’s annual production capacity for spodumene lithium concentrate from 270,000 tons to 520,000 tons.

The bank guarantee enables Sigma Lithium to obtain development bank financing and represents a milestone in the company’s 2026 growth plan. The second plant will replicate the environmentally sustainable technologies and processes used in the company’s existing first plant.

The bank guarantee is conditional upon reaching final written agreements with all parties, with terms consistent with those set out in the preliminary letter of intent.

Ana Cabral, co-chair of Sigma Lithium, said that support from the bank partner and global customers highlights the strength of the partnership, the competitiveness of the company’s products, and confidence in its management team and business strategy.

Additionally, U.S. bank securities analyst Rock Hoffman raised his rating on Sigma Lithium from Neutral to Buy, lifting the price target from $14.00 to $17.00. The analyst said, “We upgraded SGML from Neutral to Buy because we are more confident the company can address its recent liquidity challenges, resume normal operations, and achieve scale expansion.”
