São Paulo,Brazil – (October 23, 2024) – Sigma Lithium Corporation (“Sigma Lithium” or the “Company”) (NASDAQ:SGML, BVMF: S2GM34, TSXV: SGML), a leading global lithium producer dedicated to powering the next generation of electric vehicles with carbon neutral, socially and environmentally sustainable lithium concentrate, announces the shipment of 22,000t of Quintuple Zero Green Lithium to Abu Dhabi’s IRH, maintaining its consistent operational cadence with near-monthly shipments. This represents Sigma’s first transaction with IRH, broadening its commercial strategy with partners with strong balance sheets. This shipment demonstrates a shared commitment of Sigma Lithium and IRH to create a low cost, resilient global supply chain of lithium materials built upon a foundation of traceability and ethical sourcing of lithium chemicals.On September 30, 2024, Sigma concluded an export sale at its Victoria Port warehouse for 9,000t of Quintuple Zero Green Lithium concentrate with the additional 13,000t balance of the total 22,000t shipment to IRH booked in the fourth quarter.

The value of the Quintuple Zero Green Lithium for this 13^th^ shipment is initially set at a provisional floating price equivalent to 8.25% of battery grade lithium carbonate quoted at the Guangzhou Futures Exchange (GFEX).

The achievement of a near-monthly shipment cadence increases the commercial flexibility of the Company, allowing it to further its diversification strategy, and help global battery supply chains decarbonize.

All in, production of Quintuple Zero Green Lithium concentrate for the third quarter totaled 60,237t, surpassing the Company’s 60,000t target. This includes numerous daily production records and periods of sustained operations above 860t per day. The performance represents a 22% increase from 2Q24 levels and demonstrates the Company’s ability to achieve sustained production levels at annualized design capacity of 270,000t of lithium concentrate.

CEO and Co-Chairperson Ana Cabral notes: “Weare delighted to begin a commercial alliance with Abu Dhabi’s IRH, marking our collaboration to build a supply chain of lithiummaterials that are ethically produced, low carbon, environmentally and socially sustainable. This alliance will offer a resilient supplyof lithium materials that are an alternative to the prevailing opaque sourcing of lithium chemicals, which determine lithium pricing inthe industry irrespectively of traceability.

IRH is a leading participant in metals trading,backed by Abu Dhabi’s strong balance sheet. The relationship with IRH is evidence of a growing focus on battery metals by Abu Dhabimore broadly. As we continue to broaden our commercial alliances, Sigma Lithium is creating a more resilient commercial operation focusedon offering metallurgically unique and ethically sourced lithium materials: which should deliver superior price realizations over time.”

“We are also very pleased with our increasedoperational performance, which delivered on production targets for the third quarter and continues the same stride into the fourth quarter.We remain on track to deliver on our brownfield investments, while executing the strategic initiatives laid out at our recent investorday,” she concluded.
