SEC filingSigma Lithium's FY2024 net loss widened to $70.0M from $38.2M, as a 15% revenue increase was more than offset by sharply lower gross margins and $45.3M in foreign exchange losses, while the company advances Phase 2 expansion to double capacity.
Sigma Lithium's revenue for FY2024 rose 15.2% to $208.7 million, driven by a 75.4% increase in sales volume to 236.8 thousand tonnes of lithium concentrate. However, this volume growth was partially offset by lower realized prices and negative provisional price adjustments totaling $64.2 million. Cost of goods sold surged 78.1% to $164.5 million, reflecting higher mining costs ($75.0 million vs $29.7 million) and processing costs ($39.7 million vs $34.5 million), resulting in gross profit falling 50.2% to $44.3 million and gross margin contracting from 49.0% to 21.2%.
Operating expenses declined significantly, with general and administrative expenses down 53.6% to $25.2 million and stock-based compensation down 76.2% to $11.2 million, reflecting cost control measures and lower share-based grants. As a result, the operating loss before financial items improved from $21.6 million to $6.2 million. However, net loss widened to $70.0 million ($0.63 per share) from $38.2 million ($0.35 per share), primarily due to a $45.3 million foreign exchange loss from the 28% depreciation of the Brazilian Real against the U.S. dollar and a $7.0 million contractual penalty for non-compliance with loan covenants.
Total assets decreased slightly to $470.6 million from $487.2 million, driven by a $36.9 million reduction in property, plant and equipment due to currency translation and depreciation. Cash and cash equivalents remained relatively flat at $66.1 million. Trade accounts receivable fell 43.9% to $16.7 million as fourth-quarter shipments were partially collected by year-end. Inventories increased 19.4% to $23.2 million, mostly from spare parts.
Total liabilities rose to $337.7 million from $273.0 million, with loans and export prepayment balances increasing 46.1% to $249.7 million. Current liabilities more than doubled to $156.5 million, driven by higher current debt. Equity declined to $132.8 million from $214.3 million due to the net loss and unfavorable currency translation adjustments. The debt-to-equity ratio increased to 1.88 from 0.80.
Cash used in operating activities improved to $24.3 million from $30.8 million, as net loss was partially offset by non-cash items such as stock-based compensation ($11.2 million), depreciation ($19.0 million), and interest accruals. Working capital changes consumed $26.1 million, mainly from increases in inventories and advances to suppliers. Interest payments totaled $43.6 million, up significantly from $0.5 million in 2023, reflecting higher debt levels.
Investing activities consumed $32.6 million (down from $82.2 million), with capital expenditures of $23.1 million for property, plant and equipment and $4.2 million for exploration. Financing activities provided $72.1 million, primarily from $233.6 million in new export prepayment trade finance lines, partially offset by $166.5 million in repayments. Free cash flow (operating cash flow less capex) was negative $56.9 million, indicating ongoing reliance on external financing.
Management highlighted the successful ramp-up of Phase 1 production, achieving 240,800 tonnes of lithium concentrate in 2024. The company issued a final investment decision for Phase 2 in March 2024, which will add 250,000 tonnes per annum of capacity to bring total nameplate to 520,000 tpa. Phase 2 construction began in late 2024, with commissioning of the crushing circuit expected in late Q2 2025 and commercial production in Q3 2025. The project is financed by a BRL 486.8 million development loan from BNDES, subject to providing a bank guarantee.
For 2025, Sigma set a production target of 270,000 tonnes and a unit operating cost target of US$500 per tonne on a CIF China basis. The company also filed an updated technical report with increased mineral reserves (76.4 Mt at 1.29% Li2O) and a combined after-tax NPV of US$5.7 billion at 5.3% concentrate grade.
Key risks identified include lithium price volatility, foreign exchange fluctuations (particularly BRL/USD), counterparty and liquidity risks, and challenges in obtaining permits and maintaining social license. Opportunities include growing EV battery demand, expansion to capture market share, and potential sales of by-products (petalite, hypofines) to improve economics.
The company operates as a single reporting segment. Revenue was entirely from high-grade lithium concentrate ($208.7 million) with no contribution from green by-products in 2024. Stock-based compensation expense totaled $11.2 million (down from $47.0 million), reflecting fewer new grants and forfeitures. Total debt increased to $249.7 million, comprising $86.5 million in short-term trade finance and $163.1 million in long-term export prepayment agreements. The contractual penalty of $7.0 million was recognized for non-compliance with certain covenants under the Synergy facility. Foreign exchange losses of $45.3 million were primarily related to BRL depreciation against the USD, which also affected the translation of Brazilian subsidiary assets. No dividends were declared or paid.
