---	---
·	The Transaction represents the inaugural solution for the Company developed in tandem with Banco do Brasil to deepen Sigma Lithium’s commercial partnerships during the seasonal lithium purchase cycles.
---	---
·	As a result of the Transaction, Sigma Lithium will gradually phase out existing trade finance lines (drawn but mostly unused in the Company’s treasury) and move from a position of receiving advance payments (at a higher cost) to providing vendor financing and widening its client base.
---	---
·	The Transaction allows Sigma Lithium to further improve its competitive position by strengthening commercial flexibility with the goal of institutionalizing a premium for its lithium concentrate.
---	---
·	The Company’s ability to access this category of export financing demonstrates it has achieved maturity as producer within its first year of operations.
