JPMorgan cuts Sigma Lithium stock rating on mining suspension

JPMorgan downgraded Sigma Lithium (SGML) to Neutral, lowering its price target to Cdn$16.00 from Cdn$20.00 due to a temporary mining suspension and increased uncertainty. The stock has fallen 13% in the past week and 42% in six months. JPMorgan reduced its 2027 volume and EBITDA forecasts, while raising its cost of capital. Despite challenges, InvestingPro notes the stock may be undervalued. Sigma Lithium reported record Q2 2026 revenue of $55 million but faces legal and operational hurdles.
