SAO PAULO (May 16, 2024) – SIGMA Lithium Corporation (“Sigma Lithium” or the “Company”) (NASDAQ: SGML, TSXV: SGML, BVMF: S2GM34), a leading global lithium producer dedicated to powering the next generation of electric vehicles with carbon neutral, responsibly sourced chemical grade lithium concentrate, today announced its results for the first quarter ended March 31, 2024. The Quarterly Filings and accompanying Management Discussion and Analysis (“MD&A”) are available on SEDAR+ (www.sedarplus.ca), EDGAR (www.sec.gov) and the Company's corporate website.


Ana Cabral, Co-Chairperson and CEO said: "During 2024, Sigma has delivered on several key milestones aimed at doubling industrial capacity by 2025. We made the final investment decision to initiate construction of a second Greentech plant, and we extended operational life to 25 years at Grota do Cirilo by increasing our audited proven and probable mineral reserve by 40%. Our entire team is focused on the execution of this industrial and mineral capacity expansion, repeating the success of Phase 1 by delivering this second stage of operational growth on time and on budget.”









She added: “Operationally, our team has been progressing consistently towards achieving robust cash flow generation for 2024. We continue to premiunize the price of our Quintuple Zero Green Lithium, increasing May prices by 11% from April, and a nearly 30% from the 1Q24 average realized prices. We reduced reported cash cost by 16% vs 4Q23, approaching guidance.

Sigma Lithium made two full shipments of its Quintuple Zero Green Lithium concentrate during the first quarter as the March shipment was concluded in the first week of April.

·Sales were supplemented by an additional sale to Glencore AG of volumes at port totalling 8,700/t at the end of the quarter.
·Revenues associated with volumes sold in the first quarter totaled $49 million, implying a realized FOB sales price of $930/t.
·Reported revenues for the first quarter totaled $37.2 million (C$50.4 million).
oProvisional price adjustments reduced 1Q24 revenues by USD $12 million, an improvement from the $30 million price adjustment in 4Q23, as lithium concentrate prices turned upward after the Lunar New Year.


Cash unit operating costs(1) for lithium concentrate produced at the Company’s Grota do Cirilo operations in the first quarter averaged USD $397/t. The 4Q cash cost FOB Vitoria (which includes transportation and port charges) averaged USD $462/t (or $483/t with royalties).

·This is a nearly 16% improvement from the reported FOB costs in 4Q23 and is an important step to meeting Company cost targets of $370/t plant gate and $420/t FOB.
·Sigma Lithium has already seen an improvement in its cost structure given productivity actions taken, and notes that production at the processing plant was the primary hinderance to achieving guided costs during the first quarter. The Company reiterates its expectation to achieve guidance within 2Q24 for 3Q average realization.


The Company delivered first quarter adjusted EBITDA of $5.9 million (C$8.1 million), reflecting a margin of 15.8%. Reported EBITDA for the first quarter totaled $3.1 million (C$4.3 million).

·This number includes $0.5 million (C$0.7 million) of non-recurring expenditures, including those associated with the strategic review, and $2.3 million (C$3.1 million) in non-cash stock-based compensation expenses.


1Q24 results had a $12 million provisional price adjustment to revenues resulting from shipments in the 4Q23. Without this provisional price adjustment, the Company delivered a pro forma adjusted EBITDA for business conducted in 1Q24 of $17.4 million, implying a margin of more than 35%.


Net income in the quarter was a loss of $7.0 million (C$9.3 million), or ($0.06) per diluted share outstanding.


Operational Update and Phase 2 Expansion


Lithium concentrate production in the first quarter totaled 54,168 tonnes, compared to the 59,938 tonnes produced in 4Q23. No single factor weighed materially on production, but it was impacted, in part, by holiday seasonality and fewer work days. Sigma maintained a delivery schedule of approximately 35 days. The Company has successfully continued to improve Greentech plant efficiency in 2024, and notes that production improved sequentially through the course of the first quarter.








On April 1, 2024, the Board of Directors announced a Final Investment Decision (“FID”) for the Company’s Phase 2 Greentech Plant expansion. The project is expected to add 250,000 tonnes of production capacity to the current 270,000-tonne Phase 1 operation. Earthworks engineering is ongoing. Building and commissioning are expected to occur within 12 months of the FID announcement, with the first commercial production expected in 2Q25. The total expected capex for the Phase 2 construction is $100 million (C$136 million), and the Company has already secured all relevant environmental licenses to build and operate the second Greentech Plant.


Ninth Shipment Scheduled for the week of May 20


The Company is also announcing today that it has finalized pricing discussions for its ninth shipment of Quintuple Zero Green Lithium concentrate scheduled for the week of May 20th. The 22,000/t shipment will be priced at the formula of 9% of the LME/Fastmarkets lithium hydroxide benchmark, implying $1,290/t at today’s market ($1,459/tonne gross of VAT).


The current value of the May shipment reflects an 11% price increase over the Company’s eighth shipment in April, where the $1,160/tonne secured price was equivalent to 8.75% of the LME/Fastmarkets Lithium Hydroxide prices.


A similar price discovery process was followed through closed private bidding for the fixed portion of the price formula, though the final economics will depend on LME/ Fastmarkets lithium hydroxide benchmark at one month after the landing of the shipment. Sigma Lithium will continue to adapt its marketing strategy to maximize the commercial value of its premium Quintuple Zero Green Lithium


Sigma Lithium Commercial Director Catarina Noci, stated: “The economics for our May shipment represent a continuation in the market recovery that started in the days following the Lunar New Year. Indications from the market point to a firm outlook for lithium concentrate as we enter the price discovery process for our next shipment in June. Demand for our Quintuple Zero Green Lithium continues to be robust as a result of its superior chemical properties and coarse particles. We will evolve our pricing strategy to follow market dynamics in order to capture as much as possible of the 20-30% cost savings embedded in the “value-in-use” we deliver to our downstream clients.”


Balance Sheet & Liquidity


Sigma Lithium ended the first quarter with $108.2 million (C$146.4 million) in cash and cash equivalents. This represents a material increase from the $48.5 million in cash at the quarter ended Dec. 31, 2023. At the end of the quarter, the Company had $201 million (C$272 million) in short and long-term loans and export prepayment liabilities. This included $89 million in drawn and available, but unutilized, liquidity through trade finance lines.


Capital expenditures during the first quarter totaled $5.6 million (C$7.6 million) directed towards maintenance, exploration as well as incremental investments in the Greentech Plant to boost production. In total, the Company’s net debt position over the course of 1Q increased by $13 million, reflecting the annual interest payment made in connection with the outstanding debt.


Free cash flow was a modest drag as a result of lower market prices in the quarter, higher receivables, as well as the conclusion of the March shipment taking place in the first week of April (resulting in one less shipment made during the 1Q24 compared with 4Q23).

(1)Cash Operating Costs per tonne include mining, crushing, processing, and site administration expenses. When shown as Freight on Board (FOB), these expenses include transport and port charges. For clarity, non-site G&A, and royalty costs are excluded unless otherwise noted.
(2)Adjusted EBITDA represents a cash operating profit metric that nets revenues against cost of goods sold, selling, general, administrative and other cash operating expenses. Adjusted EBITDA also excludes stock-based compensation and certain non-recurring expenses, such as those related to the Company’s strategic review.
(3)Pro forma Adjusted EBITDA utilizes the same formula as Adjusted EBITDA, though it backs out the implications of the provisional price adjustment to associated revenues and costs. The Company believes this is a more accurate reflection of business conducted within the quarter.
