Toronto, September 7, 2026
–
Sigma Lithium Corporation (NASDAQ: SGML) (ASX: SAU) (TSX-V: SGML) (BVMF: S2GM34) (“Sigma Lithium” or the “Company”),
the largest producer of industrial-mineral lithium oxide concentrate in the Americas¹ and dedicated to supplying global producers
of batteries for energy security with sustainable and traceable lithium materials, confirms that its mining and industrial activities
continue operating and that the Company has not received any legal communication regarding a preliminary judicial ruling issued without
due process, allegedly suspending its environmental licenses.
Sigma Lithium remains focused on scaling
up its mining operations to advance its expansion plans and expecting to deliver 240,000 tonnes of lithium oxide concentrate within 12
months and 330,000 tonnes in FY 27, as per its recent announcement on the closing of a successful agreement with the Minas Gerais State
Authorities to resume activities (“TAC Agreement”).
This preliminary ruling suspending the
Company’s environmental licenses was reported to have been issued during a recess of Brazilian courts in the courts of the town
of Teofilo Otoni – over 300km away from Vale do Jequitinhonha and Sigma Lithium's operations, which support 19,000 job positions
and their approximately 80,000 family members.
THE COMPANY HAS NOT
RECEIVED ANY LEGAL COMMUNICATIONS
Sigma Lithium clarifies that
it has not received any legal communication regarding this preliminary ruling.
The Company believes this ruling
is unwarranted and in dissonance with Brazil's strong rule of law, as due process has not been followed.
The Company has taken appropriate measures
during the recess of the judiciary over a three-day national holiday and will begin its legal defense as soon as the courts resume regular
operations on September 8.

This preliminary ruling includes the potential
for a daily fine that would only be due only in the event the charges resulted in a final negative ruling – this would require the
full due legal process to be completed, including rights of appeal in the appropriate federal courts, including the Supreme Tribunals.
The other elements of the preliminary
ruling would also not be expected to be enforced until the completion of full due legal process. Legal jurisprudence for similar cases
indicates a timeline of multiple years until this happens. As such, no payments would be due or required.
Sigma Lithium has consistently acted in
a transparent manner with federal, state and municipal authorities and has provided extensive technical, environmental and quantitative
evidence regarding its operations. The Company remains committed to operating transparently, responsibly and in accordance with applicable
Brazilian laws and regulations.
INNACURATE REPORTS
Sigma Lithium vehemently denies media
reports stating that this preliminary ruling would have an overruling effect on the Company’s recent all-encompassing TAC Agreement
with the Minas Gerais State Authorities.
·
Brazil is entering the
final weeks leading up to the second round of its general election on November 15, which is expected to be decided by a narrow margin.
·
Minas Gerais is a key
battleground state, with the second largest numbers of eligible voters in Brazil.
·
Vale do Jequitinhonha
has become a swing district since the last general election.
·
As a result, until then,
the Company believes the frequency of inaccurate news reports about its business could increase.
ENVIRONMENTAL AND SOCIAL
SUSTAINABILITY PIONEER
Sigma Lithium has been active in Vale
do Jequitinhonha since 2012 and continues its 14-year track-record of impeccable regulatory compliance and respectful engagement with
neighboring communities.
Since inception, the Company has demonstrated
a commitment to the highest standards of environmental stewardship, recognized during several UNCCC/ COPs and by multiple global awards
for its “Quintuple Zero Lithium” that includes:
·
Absence of tailing dams
and 100% dry stacking of tailings.
·
Over 1,100 days without
accidents with lost days.
·
Absence of use of toxic
chemicals in purifying, separating and concentrating spodumene ore to create value and produce lithium oxide.
·
100% reuse of water
by the Cleantech Processing Plant, processed by the Company's inbound sewage treatment plant.
·
Bio-regeneration of
the Company's rock piles, visually evidenced by growing vegetation.
·
Low levels of noise
(even inside the mine pit).
·
Low levels of dust,
resulting from water trucks running full time at the mining operations conducting site wetting of mining pits and piles.
Sigma Lithium’s commercial success
has consolidated Brazil as a battery materials producer, establishing the country in the global lithium supply chain of industrialized
lithium oxide materials produced in an environmentally and socially sustainable manner to power data centers, battery storage and energy
security.
SIGMA LITHIUM UNWAVERING COMMITMENT
TO INTEGRITY AND TRANSPARENCY
The Company has demonstrated over the
last 14-years since inception that it has always respected the law and institutions of the Brazilian judicial system.

Sigma Lithium has always fostered the
traditions and spirituality of afro-descendants, who have enhanced the diversity of Brazilian culture into a legitimate religious syncretism
and multiculturalism.
Prior even earning a profit, the Company
pioneered support to the perpetuation of traditions practiced by our communities, including regular bus caravans to the Escrava Feliciana
(an Afro-Brazilian icon) burial ground, as well as providing ongoing financial support to cultural representative groups’ successful
endeavours.
The Company firmly opposes any attempt
to exert improper pressure or to mislead well-intentioned judicial or public officials through the submission of false, misleading or
fraudulent information, irrespective of the stated social purpose or interests such actions claim to represent. Sigma Lithium has always
conducted its business—and will continue to do so—in strict compliance with applicable laws and regulations.

FORWARD-LOOKING
STATEMENTS
This
news release includes certain “forward-looking information” under applicable Canadian and U.S. securities legislation, including
but not limited to statements relating to timing and costs related to the general business and operational outlook of the Company, the
environmental footprint of tailings and positive ecosystem impact relating thereto, donation and upcycling of tailings, timing and quantities
relating to tailings and Green Lithium, achievements and projections relating to the Zero Tailings strategy, achievement of ramp-up volumes,
production estimates and the operational status of the Grota do Cirilo Project, and other forward-looking information. All statements
that address future plans, activities, events, estimates, expectations, or developments that the Company believes, expects, or anticipates
will or may occur is forward-looking information, including statements regarding the potential development of mineral resources and mineral
reserves which may or may not occur. Forward-looking information contained herein is based on certain assumptions regarding, among other
things: general economic and political conditions; the stable and supportive legislative, regulatory and community environment in Brazil;
demand for lithium, including that such demand is supported by growth in the electric vehicle market; the Company’s market position
and future financial and operating performance; the Company’s estimates of mineral resources and mineral reserves, including whether
mineral resources will ever be developed into mineral reserves; and the Company’s ability to operate its mineral projects including
that the Company will not experience any materials or equipment shortages, any labor or service provider outages or delays or any technical
issues. Although management believes that the assumptions and expectations reflected in the forward-looking information are reasonable,
there can be no assurance that these assumptions and expectations will prove to be correct. Forward-looking information inherently involves
and is subject to risks and uncertainties, including but not limited to that the market prices for lithium may not remain at current
levels; and the market for electric vehicles and other large format batteries currently has limited market share and no assurances can
be given for the rate at which this market will develop, if at all, which could affect the success of the Company and its ability to
develop lithium operations. There can be no assurance that such statements will prove to be accurate, as actual results and future events
could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking
information. The Company disclaims any intention or obligation to update or revise any forward-looking information, whether because of
new information, future events or otherwise, except as required by law. For more information on the risks, uncertainties and assumptions
