Sigma Lithium Corp. reports first-quarter earnings before the market opens Friday, a pivotal moment for investors betting the Brazilian lithium producer can execute a sharp turnaround after a disastrous fourth quarter.
Analysts expect earnings per share of $0.12 alongside a forecasted revenue decline to $35.4 million. However, internal data shows consensus at $0.11 EPS and $43.5 million in revenue, representing a dramatic sequential improvement from the prior quarter’s $16.9 million and -$0.23 loss.
The company’s shares last traded at $18.83, giving it a market capitalization of $2.1 billion. Bank of America raised Sigma Lithium from neutral to buy and increased their price target from $14.00 to $17.00 in early April. All three analysts covering the stock rate it a strong buy.
EPS estimates have climbed 39.65% over the past 60 days, though both EPS and revenue estimates have edged lower over the past week. Revenue estimates have fallen 23.25% over two months, highlighting uncertainty around production volumes and pricing realization.
What Investors Are Watching: The earnings report will test whether Sigma Lithium’s operational restart is gaining traction. Sigma Lithium resumed mining at Mine 1 in Vale do Jequitinhonha, Brazil, with over 600 people on site and a staged ramp-up through Q1 2026 following a fourth-quarter restructuring. The question is whether the company reached steady-state production levels to generate meaningful revenue.
Investors will also scrutinize whether Sigma capitalized on surging lithium prices. Lithium prices surged in Q1 2026, with battery-grade lithium carbonate nearly doubling to US$26,278 per ton. On April 2, 2026, Sigma Lithium announced a US$100 million collateralized bank guarantee with a major Brazilian bank to unlock development bank financing for completing its Greentech Industrial Plant 2.
The path to profitability hangs in the balance. Last quarter, the company posted a -64.71% revenue surprise, missing estimates by nearly $31 million. Analysts now project a swing to positive earnings, but the company's gross profit margin of just 9.52% leaves little room for error.
Whether Sigma Lithium can deliver on its turnaround promises—or whether operational challenges persist—will determine if the recent rally holds or if the stock retreats from its 52-week high of $24.48. With lithium markets tightening and the company positioned as a key Americas producer, Friday’s report carries outsized weight.
