Sigma Lithium Resumes Sales of High-Grade
Premium Lithium Oxide; Closes Inaugural Sale
at Plant of 400,000t of High-Purity Low Grade
Fines Expecting a US$20 Million Profit
HIGHLIGHTS
Sigma Lithium is pleased to announce the resumption of sales of high-grade premium
lithium oxide concentrate in 1Q26, achieving
industrial production cadence.
In 1Q26, the Company is expected to generate gross revenues equivalent to the sale of
approximately 28,000 tonnes of high purity premium lithium oxide concentrate at a grade-
adjusted price of US$1,712 per tonne.
This achievement is a result of industrially beneficiating its dry-stacked tailings and its
inventory of raw materials into both high-purity premium lithium oxide fines and high-
purity lithium oxide.
Sigma Lithium also announces that it has executed its inaugural sale of 400,000 tonnes of
high- purity lithium fines for delivery at the plant (ex-works
EXW) with an expected profit
generated of
approximately US$20 million and at a binding fixed price for delivery of
US$50/t.
The Company now has a remaining inventory of high-purity lithium fines of 300,000
tonnes at the plant, which is expected to generate at least an additional US$15 million of
profit under current robust market conditions.
São Paulo, Brazil--(Newsfile Corp. - March 20, 2026) - Sigma Lithium Corporation (NASDAQ: SGML)
(TSXV: SGML) (BVMF: S2GM34) ("Sigma Lithium" or the "Company"),
the largest producer of lithium
oxide concentrate in the Americas¹ and dedicated to industrializing socially and environmentally
sustainable lithium materials to supply global producers of batteries for energy security, announces that it
has resumed sales of high-grade premium lithium oxide in 1Q26, achieving industrial production
cadence.
In the 1Q26, the Company expects to generate gross revenues equivalent to the sale of approximately
28,000 tonnes of high-purity premium lithium oxide at a grade-adjusted price of approximately US$1,712
per tonne. This performance reflects Sigma Lithium's ability of industrially beneficiating its dry-stacked
tailings of fines, as well an existing inventory of raw materials
into both premium high-grade lithium
oxide and high-purity lithium fines.
The Company has also executed its inaugural sale of 400,000 tonnes of high-purity lithium fines at the
plant gate to be delivered on an ex-works EXW basis at a binding fixed price of US$50 per tonne. This
transaction is expected to generate approximately US$20 million in profit.
Following this sale, Sigma Lithium retains an inventory of approximately 300,000 tonnes of high-purity
lithium fines at its plant, which is expected to generate at least an additional US$15 million in profit
considering the robust conditions for the lithium market expected to prevail during the next few months.
The commercialization of low-grade lithium fines by Sigma Lithium demonstrates a considerable
"sustainability reward and green premium" to its shareholders.
Ana Cabral, Co-Chairperson of Sigma Lithium, said:
"The resumption of sales of high-grade premium lithium oxide is in accordance with the outlook we
highlighted at our investor presentations this year. By recovering, reprocessing and thus, upgrading,
through our proprietary Greentech technology, the previously untapped lithium materials idling at our
dry stacked piles, Sigma Lithium
delivered a direct financial return on its investment in the clean
technology developed for its Greentech Industrial Plant's dry stacking processing module and
reprocessing lithium circuits, while creating a permanent new business unit that increases the volume
of high-purity lithium materials delivered to our customers, enhancing the diversification of our
product portfolio.
Sigma Lithium's VP of Business Development Marina Bernardini said:
"Our inaugural sales of high-
purity lithium fines, delivered at the plant on an ex works basis, confirms the profitability of these sales
and highlights the potential for future cash flow to be generated from the remaining inventories of high-
purity fines currently at the plant. They also further reinforce the sustainability reward for shareholders
that we have demonstrated through successive profitable sales of these products."
