CEO Remarks:

"In our first quarter of revenue generation, Sigma Lithium has achieved positive operating profit, enabled by our impressive cost-efficient operating model," said Company Co-Chairperson and CEO Ana Cabral. "Looking ahead we expect to deliver increasing production volumes at a lower cost with a high standard of quality and purity. Our cost and purity advantages, combined with our industry-leading sustainability practices, provide Sigma Lithium with a preferential position in the marketplace. We believe this gives us the flexibility to expand our production capacity regardless of evolving market conditions to more efficiently utilize our existing cost structure. As production increases, so too should shareholder value as we continue our mission to sustainably power the next generation of electric vehicle batteries."

Key Performance Metrics for Quarter Ended 30 September 2023($ USD)

Sigma Lithium generated its first revenue from the sale of its Triple Zero Green Lithium concentrate (zero tailings, zero hazardous chemicals, zero carbon) and associated Green By-Products in the third quarter, marking a major milestone in the Company's journey to become one of the largest lithium ore producers globally. In total, revenues generated in the third quarter were USD$96.9 million (C$130 million) from the sale of 38,000 tonnes of its Triple Zero Green lithium concentrate and 16,500 tonnes of lithiated Green By-products. The average realized price for Sigma Lithium's concentrate in the quarter was $2,488/tonne.  

Adjusted cash operating costs⁽¹⁾ for lithium concentrate produced at the Company's Grota do Cirilo operations averaged $505/tonne in the quarter. The adjusted FOB Vitoria cost for the third quarter (which includes transportation, and warehousing) totaled $577/ tonne (or $649/tonne with royalties). Operating leverage in the quarter was impacted by the ramp process, particularly in July, when Greentech Plant throughput was minimal. For the month of October, the Company's on-site operating ash costs per tonne were $425, while the FOB Vitoria cost was $485/tonne. While Sigma Lithium expects month-to-month variability in costs, it is providing early October data as an indication of its anticipated cost trend as production ramps. The Company expects additional traction on lowering its cash operating costs per tonne from these levels.

EBITDA for the third quarter totaled USD $53 million. This includes $3.4 million of non-recurring expenditures, including those associated with the ongoing strategic review, partially offset by the reversal of a $1.8 million tailwind from stock-based compensation. Excluding these costs, the Company delivered third quarter adjusted EBITDA of USD $54.6 million. Net income in the quarter totaled USD $36.4 million, or $0.33 per diluted share outstanding.

Operational Update

In the third quarter, Sigma Lithium continued to build on its track record of achieving operational milestones on schedule. Dense Media Separation (DMS) plant recoveries averaged 49%, with results impacted by lower plant throughput, particularly exiting the second quarter and into July. The Company has taken additional steps to boost throughput and continues to target sustained plant recovery rates of 65%.  In October, throughput averaged 61.5%, with results boosted by a daily record production volume of 890 tonnes of Triple Zero Green Lithium concentrate. For the full year, the Company continues to expect lithium concentrate production of 130,000 tonnes, as ongoing production is supplemented by the sale of Green By-products.

During the third quarter, Sigma Lithium made two shipments of Triple Zero Green Lithium concentrate, totaling 38,000 tonnes. As previously reported, the Company successfully delivered its third shipment to port in October, trucking 20,000 tonnes of Triple Zero Green Lithium, to be shipped to Glencore as part of a collaboration to create a low carbon, environmentally and socially sustainable global lithium supply chain for electric vehicles. Sigma Lithium achieved operational net-zero carbon emissions for all three of its shipments to-date through the implementation of its environmentally sustainable production methods and the purchase of carbon credits from Carbonext (as verified through Verra Verified Carbon Standard).

Sales of lithium concentrate were supplemented by the sale of 16,500 tonnes of ultra-fine tailings to Yahua International Investment and Development Co. ("Yahua").

Sigma Lithium continues to progress towards completing its Definitive Feasibility Study (DFS) and Final Investment Decision (FID) for its Phase 2 and 3 expansions. The expansion would lift Greentech Plant nameplate throughput potential to 766,000 tonnes (104,000 tonnes lithium carbonate equivalent) from the current level of 270,000 tonnes (37,000 tonnes lithium carbonate equivalent). The Company plans to update the market on its expansion progress as soon as the DFS has been completed and the FID has been made. Given Sigma Lithium's high purity Triple Zero Green Lithium concentrate and ESG credentials, we believe the Company's material has priority at converter customers. Together with our low operating cost model, Sigma Lithium remains confident in its decision to continue expanding its production capacity in the current market conditions.     

Exploration Update

On November 1 Sigma Lithium announced a likely increase of its mineral resource estimate to over 110 million tonnes, representing a 25% potential increase to the prior estimate. Notably, the Company increased the exploration potential of Phase 4 to approximately 26 to 30Mt, with ore body extensions continuing to the east, based on the drilling results received to date. This is a significant potential increase to the Grota do Cirilo mineral resource estimate, delivering further consistent high grade assay results which are to be incorporated into an updated NI 43-101 compliant technical report expected to be released in the fourth quarter of 2023.

As part of the Exploration Program, Sigma Lithium has also identified additional pegmatites that could potentially yield up to 20 Mt of incremental mineral resource in a potential Phase 5.

The Company is conducting significant exploration RC drilling, trench work and sampling, in 57 mineralized pegmatites (out of the 200 pegmatites mapped within the Company's mineral concessions). The Exploration Program defined the surface area and the weathered mineralogy for these 57 pegmatites. The Accelerated Plan will include drilling exploratory core diamond drill holes into each of these targets.

Strategic Review Process

Sigma Lithium recently announced that its strategic review process has advanced to the final round and is expected to reach a decision by the end of 2023. Remaining interested parties have "agreed-in-principle" to preserve the Company's environmental and social sustainability centered business model in a potential strategic transaction. This update follows Sigma Lithium's announcement in September that its Board of Directors had received and is reviewing multiple strategic proposals, including from global industry leaders in the energy, auto, batteries and lithium refining industries. The Board of Directors is committed to maximizing value for Sigma Lithium's shareholders, employees and communities of Sigma Brazil at Vale do Jequitinhonha through the strategic review process.

Balance Sheet & Liquidity

Sigma Lithium ended the third quarter with USD $28.2 million in cash and cash equivalents. This represents a modest draw from the $33 million in cash at the quarter ended June 30, 2023. Positive earnings contributions were offset as the Company built working capital balances on account of the first commercial shipments. Capital expenditures spent during the third quarter were under $7mn as the Company made incremental investments to its Greentech Plant. In regard to the Phase 2 & 3 expansion, Sigma Lithium is finalizing the detailed engineering, but plans to fund the expansion through free cash flow generation and additional debt financing agreements. 

Conference Call Information

The Company will conduct a conference call to discuss its financial results for the third quarter, and its outlook for the fourth quarter and full year 2023, at 8:00 a.m. EST on Wednesday, November 15, 2023. Participating on the call will be Co-Chairperson and Chief Executive Officer, Ana Cabral. To register for the call, please proceed through the following link Register here.
