Sigma Lithium Corporation shares rose 3% on Thursday following the company's announcement that it has entered into a $100 million collateralized bank guarantee with a major Brazilian bank.
The agreement calls for the bank guarantee to be fully collateralized by Sigma Lithium's clients through a combination of corporate guarantees, letters of credit and export receivables. Company executives said the facility is aimed at supporting the construction of a second Greentech industrial plant, which would increase annual production capacity from 270,000 tonnes to 520,000 tonnes of lithium oxide concentrate.
According to the company, the bank guarantee will allow access to development bank financing and is being treated as a milestone in its growth plan targeted for 2026. The second plant is planned to replicate the environmentally sustainable technologies and processes currently used at Sigma Lithium's operational first plant.
The transaction remains conditional. The bank guarantee is subject to the completion of definitive written agreements among all parties, with terms to be consistent with those set out in the preliminary letter of intention.
Company statement
Ana Cabral, Co-Chairperson of Sigma Lithium, commented on the backing from financiers and customers, saying, "the support from banking partners and global clients underscores the strength of relationships, competitiveness of the company’s product and confidence in its management team and business strategy."
Analyst action
Separately, BofA Securities analyst Rock Hoffman upgraded Sigma Lithium from Neutral to Buy and raised his price target to $17.00 from $14.00. Hoffman said, "We upgrade SGML to Buy from Neutral as we are more confident the company can navigate its near-term liquidity crunch to return to normal operations and scale."
The bank guarantee and the analyst upgrade together reflect developments intended to shore up financing and operational plans as the company advances toward a second processing facility planned to double its current output.
Contextual notes
- The guarantee is explicitly backed by client-provided collateral in three forms: corporate guarantees, letters of credit and export receivables.
- The new facility is designed to support a second plant using the same environmentally sustainable technologies as the first plant.
- The arrangement remains dependent on definitive documentation following the preliminary letter of intention.
