Insights

Financial Analyst

Sigma Lithium posts first-ever profit with strong margins despite industry headwinds, demonstrating operational efficiency and cost discipline.

Sigma Lithium has reached a significant milestone by reporting its first-ever quarterly profit of $4.7 million ($0.04 per share) in Q1 2025. This achievement comes amid challenging lithium market conditions, highlighting the company's operational resilience and cost management prowess.

The financial performance exhibits impressive margins, with a cash gross margin of 35% and adjusted EBITDA margin of 24%, underscoring the company's ability to maintain profitability despite price pressures. Revenue increased 28% year-over-year to $47.7 million, supported by production volumes of 68,308 tonnes (exceeding their target of 67,500 tonnes) and sales volumes of 61,584 tonnes.

What truly distinguishes Sigma's performance is its industry-leading cost structure. The company achieved CIF China cash operating costs of $458/t, 8% below its target of $500/t, and all-in sustaining costs (AISC) of $622/t, 6% below target. These metrics position Sigma among the lowest-cost producers globally, providing crucial buffer against commodity price volatility.

The balance sheet shows some pressure with cash decreasing 32% quarter-over-quarter to $31.1 million, driven by $4.8 million in capital expenditures, a $9 million increase in working capital, and $10.2 million in debt repayment. Total debt stands at $165.3 million.

A strategic advantage worth noting is Sigma's uncommitted production. Unlike many competitors, 100% of Sigma's production remains uncontracted, providing flexibility in a volatile market and potential leverage for securing favorable prepayment or offtake agreements to fund Plant 2 expansion.

The Plant 2 construction appears on track with long-lead equipment orders expected shortly and commissioning planned for late Q4 2025. This expansion represents a critical growth vector that should deliver economies of scale, potentially improving the already strong cost position.

While Q1 shows strong execution, investors should monitor working capital consumption and the declining cash balance, as successful funding of Plant 2 expansion will be crucial for maintaining growth momentum in this capital-intensive industry.

SÃO PAULO, May 14, 2025 /PRNewswire/ -- Sigma Lithium Corporation (TSXV/NASDAQ: SGML, BVMF: S2GM34), a leading global lithium producer dedicated to powering the next generation of electric vehicles with carbon neutral, socially and environmentally sustainable lithium concentrate, reports its results for the first quarter ended March 31, 2025.

Ana Cabral, Co-Chairperson and CEO, commented: "We reported our first net income this quarter and delivered both production volumes and costs in line with our targets. Our disciplined approach to cost management has driven strong margin performance. With our operations in Brazil strategically positioned, we have remained largely insulated from the broader effects of global trade measures. We continue to prioritize cash generation while responsibly advancing the construction of Plant 2, which is expected to deliver significant economies of scale and increased sales volumes. These initiatives reinforce our long-term resilience and support our strategic goals."

The CEO added, "As we prepare for a significant ramp-up in production, offtake and prepayment agreement options are standard industry practices that the Company has not yet employed. To date, 100% of our current and future production remains uncommitted. Any capital secured through such agreements would complement the BNDES reimbursement schedule, helping fund the construction of Plant 2 while also extending our debt maturities and reducing our cost of capital".

Revenues and Production

Sigma Lithium reported revenues of $47.7 million for 1Q25, representing a 28% year-on-year increase and a slight improvement over 4Q24 revenues, despite lower sales volumes in the quarter. Sales volumes totaled 61,584 tonnes in 1Q25, up 17% from 1Q24 but down 17% compared to 4Q24, primarily due to the timing of the accounting cutoff, which deferred a portion of shipments beyond the quarter-end.

The Company reported production volumes of 68,308 tonnes in 1Q25, slightly higher than quarter production target of 67,500 tonnes, and 26% higher compared to 1Q24. The Company expects its FY25 production to reach 270,000 tonnes.

Costs

The Company reported a cost of sales of $34.2 million for 1Q25, reflecting a 19% increase compared to 1Q24 and a 7% increase compared to 4Q24. On a per-tonne basis, the cost of sales averaged $556 per tonne of product sold, which represents a 3% increase year-over-year and a 28% increase from 4Q24. The year-on-year rise was primarily driven by higher production volumes, partially offset by lower operating costs. The increase from 4Q24 was mainly attributed to:

• Lower production volumes by 11% during 1Q25, which resulted in a higher operating cash cost per tonne;
• Higher freight and distribution costs, as CIF ocean freight costs for the last two shipments made in 4Q24 were recognized in 1Q25; and
• The allocation of stock-based compensation for operating personnel to operating costs, which began in 2025. Prior to 2025, all stock-based compensation was allocated to SG&A expenses.¹

Despite the increase in cost of sales in 1Q25, the Company's operating cash costs remain among the lowest in the industry, with CIF China cash operating costs averaging $458/t. This represents a 7% increase from $427/t in 4Q24, driven by lower production volume, and remains 9% below the 2025 cost target of $500/t.

Despite an 11% decrease in production volume in 1Q25 compared to 4Q24, all-in sustaining cost (AISC) increased by only approximately 5% to an average of $622/t, remaining below the full-year target of $660/t. While lower production was the main driver of the increase, the Company's ongoing efforts to optimize cost components within AISC partially offset the impact of lower production volume.

_________________________________

1 Starting January 1, 2025, the Company began allocating stock-based compensation for certain operational personnel directly to operating costs, in alignment with revised internal cost attribution practices. This change reflects a more accurate representation of total operating expenses. Prior to 2025, these costs were reported under general and administrative expenses.

Cash Operating Margin⁽²⁾, Adjusted EBITDA⁽⁴⁾ and Adjusted EBITDA Margin⁽⁴⁾

Sigma Lithium reported cash gross profit of $16.7 million, representing cash gross margin of 35% for 1Q25, lower than 42% reported for 4Q24. The decrease in cash gross margin is primarily driven by higher cost of sales, as outlined above.

For the first quarter of 2025, EBITDA totaled $10.0 million, representing a 21% EBITDA margin, an increase of more than three times compared to the first quarter of 2024. Adjusted EBITDA, which excludes non-cash stock-based compensation, totaled $11.4 million, reflecting a 24% Adjusted EBITDA margin, more than double the level reported in 1Q24.

Net Income

Sigma Lithium reported net income of $4.7 million, or $0.04 per share, for 1Q25, representing its first quarterly profit since commencing production. This milestone reflects the Company's continued progress in scaling production, maintaining disciplined cost control, and delivering strong operational and financial performance.

Balance Sheet & Liquidity

As of March 31, 2025, the Company's cash and cash equivalents totaled $31.1 million, representing a 32% decrease from $45.9 million as of December 31, 2024. The main uses of cash during 1Q25 were:

• Capital expenditures of $4.8 million;
• Increase in working capital of $9.0 million, mainly due to higher accounts receivable ($14.7 million) and inventories ($3.4 million) at period-end, as payment for a quarter-end deal was settled in early 2Q25; and
• Repayment of short-term debt of $10.2 million.

The Company reduced its short-term trade finance by approximately $10 million in 1Q25, bringing the balance to $51.1 million as of March 31, 2025. The total amount of short and long-term debts (net of accrued interest) was $165.3 million as of March 31, 2025. The net interest paid in 1Q25 totaled $1.1 million or approximately $17/t of quarterly production.

The Company is evaluating potential long-term prepayment and offtake agreements, in line with standard industry practices. To date, it has maintained full commercial flexibility, with 100% of its production uncommitted. Any agreements executed would form part of the Company's strategy to optimize its capital structure and support Phase 2 funding alongside BNDES reimbursements.

Operational and Phase 2 Expansion Updates

In 2025, the Company continued its process optimization initiatives at the current Greentech plant, focusing on improving ultrafines screening efficiency and stabilizing the DMS cyclones, efforts that contributed to higher recoveries in the plant's production process. As part of the 2Q25 maintenance plan, the operations team will upgrade the thickener module to enhance processed water filtration and recovery, thereby further contributing to the overall efficiency of the plant.

In the second half of May, the scheduled crusher module maintenance will involve replacing the current screens with newly designed screens, which are expected to enhance the overall quality and reliability of the crusher module, reducing the maintenance time and costs going forward.

During the first quarter of 2025, the Company continued civil works at the Plant 2 site, with approximately 200 workers engaged in construction activities. Having completed procurement and contractual negotiations, the Company expects to place orders for long-lead items in the coming months, with initial deliveries beginning in 3Q25, followed by the assembly of mechanical structures.

Footnotes & Reconciliations:

To provide investors and others with additional information regarding the financial results of Sigma Lithium, we have disclosed in this release certain non-IFRS operating performance measures such as unit operating costs, EBITDA, EBITDA margin, Adjusted EBITDA, and Adjusted EBITDA margin. These non-IFRS financial measures are a supplement to and not a substitute for or superior to, the Company's results presented in accordance with IFRS.  The non-IFRS financial measures presented by the Company may be different from non-GAAP/IFRS financial measures presented by other companies. Specifically, the Company believes the non-IFRS information provides useful measures to investors regarding the Company's financial performance by excluding certain costs and expenses that the Company believes are not indicative of its core operating results. The presentation of these non-U.S. GAAP/IFRS financial measures is not meant to be considered in isolation or as a substitute for results or guidance prepared and presented in accordance with U.S. GAAP/IFRS.  A reconciliation of these financial measures to IFRS results is included herein.

1. Cash unit operating costs include mining, processing, and site based general and administration costs. It is calculated on an incurred basis, credits for any capitalised mine waste development costs, and it excludes depreciation, depletion and amortization of mine and processing associated activities. When reported on an FOB basis, this metric includes road freight, and port related charges. When reported on a CIF basis it includes ocean freight, insurance and royalty costs. Royalty costs include a 2% government royalty and a 1% private royalty.

For CIF operating cost analysis purposes, the Company uses the ocean freight costs of products that sailed during the reporting period. However, for accounting purposes, and therefore in this quarter's reported cost of good sold and revenues, ocean freight is treated as a service provided to a customer and is recognized when the product is delivered. 

Cash unit all-in sustaining cost includes unit CIF China cash operating cost, SG&A, maintenance capex and financial expenses.

2. Cash operating profit represents revenue less cost of sales (COGS), excluding depreciation and amortization (D&A) expenses. Cash operating margin is cash operating profit divided by total revenue for the period.

3. Average revenue per tonne is calculated as total revenue for the period divided by total sales volume in tonnes. Average COGS per tonne is calculated as total cost of sales (COGS) for the period divided by total sales volume in tonnes.

 4. Adjusted EBITDA is a measure of the Company's recurring core earnings profile. It is calculated as revenue minus cash operating and selling expenses. The calculation excludes non-cash items such as depreciation and amortization (D&A) and stock-based compensation expenses. Adjusted EBITDA margin is calculated by dividing Adjusted EBITDA by total revenue for the period.
