On January 8, 2026, Bank of America (“BofA”) downgraded Sigma Lithium to Underperform from Neutral, citing unresolved operational and liquidity issues.  BofA asserted that management has not yet provided clarity on the resumption of mining or receipt of cash from prepayments, both of which are crucial to alleviating balance sheet concerns. 

Following the downgrade, Sigma Lithium’s stock price fell $2.36 per share, or 15.07%, to close at $13.30 per share on January 8, 2026.
