SIGMA LITHIUM CO-CHAIRS CONCLAVE AT SAUDI ARABIA’S FII SUMMIT IN BRAZIL; HOSTS DELEGATION FROM THE WHARTON SCHOOL AT ITS GREENTECH PLANT IN VALE DO JEQUITINHONHA

FUTURE INVESTMENTS INITIATIVES

Sigma Lithium was honored to join a delegation from Saudi Arabia, the President of Brazil, the Governor and Mayor of Rio de Janeiro and business leaders at Saudi Arabia’s Future Investments Initiatives Priority Summit held in Rio de Janeiro, ahead of the 2024 G20 summit in Brazil.

Under the theme "Invest in Dignity,” Saudi Arabia's first flagship summit in Brazil explored investing in the energy transition, technology, and how social inclusion can build a global order that prioritizes dignity for all.

Sigma Lithium’s Vice President of Institutional Relationships and Government Affairs, Ligia Pinto, co-chaired a discussion conclave with Saudi Aramco on “Transforming Foundations Beyond Energy: The Imperative of Materials Transition” and joined the CEO of Vale and the President and CTO of Lilac Solutions in a discussion about the “Geoeconomics of Mining & Critical Resources.”

Sigma Lithium shared its sustainability journey on a topic that is at the core of the Company’s purpose and ethos: improving the lives of the people of Brazil’s Jequitinhonha Valley, where its operations are based.

WHARTON

Sigma Lithium also hosted a delegation of professors from the Wharton School of the University of Pennsylvania at its industrial site in Brazil’s Vale do Jequitinhonha in Minas Gerais.

The tour provided a concrete experience of Brazil's burgeoning role in the global lithium industry and the energy transition and an opportunity to learn more about the production of Sigma Lithium’s Quintuple Zero Green Lithium.

São Paulo, Brazil – (June 19, 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, was honored to join the Saudi Arabian delegation, the President of Brazil, the Governor and Mayor of Rio de Janeiro and several prominent business leaders at Saudi Arabia’s Future Investments Initiatives Priority Summit held in Rio de Janeiro, ahead of the 2024 G20 summit in Brazil.

FII: INVEST IN DIGNITY

Sigma Lithium’s Vice President of Institutional Relationships and Government Affairs, Ligia Pinto, Co-Chaired with Saudi Aramco the Conclave “Transforming Foundations Beyond Energy: The Imperative of Materials Transition.”

Sigma Lithium shared its sustainability journey on a topic that is at the core of the company’s purpose and ethos: improving the lives of the people of Brazil’s Jequitinhonha Valley, where its operations are based.

“Invest in Dignity” is a theme that’s close to Sigma Lithium’s founding principles and to the people of Brazil’s Jequitinhonha Valley, where Sigma Lithium’s operations are based. Formerly one of the country’s poorest regions, the valley’s economy is now growing by 20% a year, a result of the creation of over 14,000 jobs, billions of reals in planned investments and Sigma Lithium’s social inclusion programs (microcredit and family agriculture support, amongst Brazil’s largest).

“We delivered to the world a new lithium project in the Brazilian way, socially and environmentally sustainable,” Pinto said.

Pinto also spoke in the panel discussion “Geoeconomics of Mining & Critical Resources”, where she joined the CEO of Vale, the President and CTO of Lilac Solutions (a U.S.-based designer and builder of lithium extraction solutions backed by Gates Ventures) and Jose Luis Manzano, (President of Argentina’s Integra Capital). Here, she stressed that “the world ought to ponder putting aside geoeconomic rivalries to achieve a just and inclusive energy transition that collectively accelerates tackling climate change”.

“Brazilians should be proud of Sigma because it has brought worldwide good practices to the lithium industry,” said Jose Luis Manzano, President of Argentina’s Integra Capital.

“At Sigma Lithium we are enablers,” Pinto said. “We're shipping a new product to the world, the Quintuple Zero Green Lithium, which has superior technical qualities and embodies the environmentally sustainable just transition as it is produced in line with the ethos of electric vehicles. We are here to supply every supply chain focused on these attributes, in all countries."

“A stark reminder of the urgency of tackling climate change for humanity is demonstrated by Brazil’s recent tragic experience with the floods in the south of the country, leaving hundreds of thousands Brazilians displaced from their homes” She added.

WHARTON

Sigma Lithium also hosted a delegation of professors from the Wharton School of the University of Pennsylvania at its industrial site in Brazil’s Vale do Jequitinhonha in Minas Gerais.

Following the Wharton Global Forum, which was hosted in São Paulo this year, the tour provided a concrete experience of Brazil's burgeoning role in the global lithium industry and the energy transition and an opportunity to learn more about the production of Sigma Lithium’s Quintuple Zero Green Lithium (zero carbon, zero usage of potable water, zero tailing dams, zero dirty power, zero toxic chemicals).

The senior group of professors visited Sigma Lithium’s integrated mining and processing facilities at Araçuaí and met some of the more than 700 female entrepreneurs who have participated in Sigma’s microcredit program.
