Toronto, Ontario--(Newsfile Corp. - September 16, 2026) - Sigma Lithium Corporation (NASDAQ:
SGML) (ASX: SAU) (TSXV: SGML) (BVMF: S2GM34) ("Sigma Lithium" or the "Company"), the largest
producer of industrial-mineral lithium oxide concentrate in the Americas¹ and at the intersection of clean
energy for data centres and sustainable development, was selected by Nasdaq to ring closing bell
during United Nations Climate Week in New York in recognition of upholding one of the highest
sustainability standards in critical minerals.
This is a demonstration of Sigma Lithium's successful pioneer business model combining the highest
standards of environmental and social inclusion in the critical minerals industry with shareholder value
creation, as it built the fifth largest lithium industrial mineral complex in production globally.
SUSTAINABILITY EXCELLENCE RECOGNIZED BY NASDAQ
Sigma Lithium was once again selected by Nasdaq to participate in its Closing Bell Ceremony during
New York Climate Week, recognizing the Company's pioneering sustainability leadership and
impeccable track record of translating environmental and social principles into measurable action.
This year's Closing Bell Ceremony carries particular significance, as Sigma Lithium celebrates five
years since its Nasdaq listing, marking the Company's remarkable evolution from pre-construction
development into the largest industrial mineral producer of lithium oxide concentrate in the Americas,
while maintaining sustainability at the core of the way it has designed, built and operates its business.
Ana Cabral, CEO and Co-Chairperson of Sigma Lithium, stated:
"Being selected once again to ring the
Nasdaq Closing Bell during Climate Week is a recognition of Sigma Lithium's unique journey.
During
the last five years we have resiliently navigated volatile lithium price cycles without diluting
shareholders, while diplomatically managing through domestic political democratic polarization,
multipolar geopolitics, and increased fuel costs resulting from international wars. We are immensely
proud of our team for working relentlessly since the inaugural listing in the United States, to deliver on
all our business targets and a wave of prosperity to our neighbours in Lithium Valley.
"
The Company has turned environmental and social commitments into concrete and measurable
sustainability action in one of the most economically disadvantaged regions in South America resulting
into unwavering community support for Sigma Lithium, with over 2,000 people demonstrating support for
the Company at its last environmental licenses public hearing.
Sigma Lithium believes that its neighbors are fundamental to its success and that the economic
opportunities generated by the Company's operations should translate into lasting benefits for the
communities where it operates. As a key economic growth engine in the Vale do Jequitinhonha, Sigma
Lithium has contributed to the creation of 19,000 job positions, benefiting approximately 80,000 family
members in one of the most economically underserved regions of the State of Minas Gerais.

SIGMA LITHIUM STRONGLY CONTESTS PRELIMINARY RULING;
OPERATIONS CONTINUE NORMALLY
Sigma Lithium confirms that its mining and industrial operations continue normally. The Company
strongly contests the preliminary ruling concerning its environmental licenses and has pursued the legal
remedies available under Brazilian law to seek its prompt reversal. Importantly, the dispute has no effect
on Sigma Lithium's mining rights or the ownership of its mining concessions. The matter relates
exclusively to surface rights and the potential expropriation of land from small-scale farmers.
Sigma Lithium's mining and industrial assets and mineral rights remain unaffected by the preliminary
ruling. The Company does not hold any mining concessions within either the original or the newly
claimed areas proposed for recognition as Quilombolas. Since 2017, the Company's operations have
been measured to be approximately 50% farther from the Afro-Brazilian heritage community than the
applicable legal distance threshold.
The preliminary ruling was issued during a holiday period by a judge acting on weekend duty. The
Company maintains that the ruling was issued without observance of due process, without adequate
legal grounds and without providing the Company with an opportunity to present its environmental
technical defense. Sigma Lithium believes the ruling is inconsistent with the prevailing legal framework
and applicable jurisprudence and remains confident that, upon full judicial review, Brazil's strong Rule of
Law will prevail, as it has in previous claims brought against the Company that did not ultimately
succeed.
Importantly, Sigma Lithium has not been personally served with the preliminary ruling. The decision
remains subject to review by the competent appellate courts, before which the Company has presented
a robust legal defense seeking its reversal. Sigma Lithium therefore remains firm in its legal position and
continues its operations while pursuing all remedies available under Brazilian law.
The preliminary ruling provides for a R$100,000 penalty in the event of non-compliance. This amount
does not alter the Company's assessment of the merits of the case or its confidence in the legal
remedies already pursued.
The Company believes that the broader legal framework governing projects located in proximity to
traditional communities has generated an evolving and substantial body of administrative and judicial
precedent requiring case-specific technical evidence, clearly established territorial boundaries and full
observance of due process. According to the Company, comparable claims have frequently been
overturned or otherwise failed to prevail upon appellate review, and these principles strongly support its
position in the current proceedings.
In recent years, Brazil has experienced an increasing number of territorial claims involving areas located
near major infrastructure, mining, agricultural and industrial projects, including claims seeking recognition
of progressively larger areas as traditional Quilombola territories. These cases have generated an
evolving body of administrative and judicial precedent emphasizing the importance of technical
evidence, properly established territorial boundaries and strict adherence to due process.
With respect to the specific claim involving the Company:
The number of families and the boundaries of the claimed heritage area have been the subject of
controversy within the relevant federal regulatory process. Three contradictory decrees concerning
the Quilombola claim were issued within a period of less than one year, including one decree that
entirely cancelled the rights arising from the request.
The claim alleges that the Company's operations affect a Quilombola community located more
than 12 kilometres away from the operations, exceeding the applicable eight-kilometre distance
referenced in the proceedings.
The Company conducted a baseline social study of population origins several years prior to
initiating operations.
According to the Company's technical evidence, the nearest residence occupied by individuals
who self-identify as members of the relevant Quilombola agricultural community is located beyond
the referenced 8 kilometre distance.
The request for the assignment of agricultural land to establish the claimed Quilombola territory
was presented by an individual described in the proceedings as a self-appointed community
leader who resides in the city of Araçuaí, approximately 20 kilometres from the claimed heritage
area.
According to information made public by the 14 heirs of the deceased owner of land within the
claimed area, an alleged real-estate arrangement existed between their father and the individual
presenting himself as the community leader.
The original request sought recognition of approximately 500 hectares (2,3km2 or 1,235 acres).
A new request filed in 2025 increased the claimed area to 15,000 hectares (182 km2 or 37,000
acres).
The expanded area claimed in 2025 is larger than the municipality itself and each of 14
neighbouring municipalities in the Jequitinhonha Valley.
Sigma Lithium maintains that the facts and technical evidence demonstrate that its environmental
licenses remain legally valid. The Company remains confident that a complete judicial review, supported
by the applicable legal framework, established territorial evidence and full observance of due process,
will result in the reversal of the preliminary ruling. Sigma Lithium will continue operating normally while
firmly defending its rights and pursuing all remedies available under Brazilian law.
