This price is final and non-provisional and represents a meaningful increase over the previous premium prices achieved by the Company.

As a reference, the final price net of VAT is equivalent to 8.75% of the LME Lithium Hydroxide CIF/Fastmarkets CJK price.
Price discovery was driven through closed private bidding, aiming to maximize the value of its commercial shipment strategy. Sigma Lithium will continue to adapt its marketing strategy to maximize value capture.

Included in the agreement is a cash prepayment clause, with 85% of the shipment's value collected by loading.

The shipment is part of a commercial distribution and marketing agreement with Glencore that aims to build a low carbon, environmentally and socially sustainable global lithium supply chain for electric vehicles.

This milestone achievement represents a significant improvement in commercial terms for Sigma Lithium, consolidating our leadership in the industry as a large-scale producer of Quintuple Zero Green Chemical Grade Coarse Lithium.

The premium achieved demonstrates the product's superior quality (chemically and physically quantifiable), as follows:

High-purity: low alkalines and low iron oxide enable improved performance of refineries during transformation of the material into high-purity battery grade chemicals certified by leading battery producers.
Coarse particles over 5.5mm: improve efficiency and performance for refiners during calcination.

Sigma Lithium Commercial Director, Catarina Noci, notes: "The Company continues to field inbound interest at a feverish pace for our next shipments. We were on the ground in China over the last month with Glencore where it became clear to us that our Quintuple Zero Green Chemical Grade Coarse Lithium concentrate gained significant market share, delivering measurable savings to our customers' refineries as a result of our Products' superior physical and chemical properties. Our Product becomes increasingly valuable to our customers when markets are soft, where non-integrated refiners and tollers alike are experiencing tighter operating margins. Sigma Lithium views the warm welcome, incredible demand and favorable commercial terms extended to us, as a reflection of the customers having experienced, over the last 7 months, the remarkable performance and cost savings that Sigma Lithium's Product brings to their refineries. Therefore, we were able to monetize these tangible costs savings provided to our customers by the Product into a "high quality premium".

Company CEO, Ana Cabral-Gardner notes, "The Company is now fully established as a leading producer, as a result of consistently delivering large scale shipments of a high-quality Quintuple Zero Green Chemical Grade Coarse Lithium over the last 9 months. Therefore, we entered negotiation rounds for our 8^th shipment with significant commercial leverage. The increased premiumization is attributable to the superior performance of our Product for our refining clients who were able to ascertain its efficiency gains and cost savings. Additionally, as a "free bonus" we deliver the only Quintuple Zero Green Lithium in the industry, without receiving a green premium.
