São Paulo, BRAZIL – (October 26, 2023) – Sigma Lithium Corporation (“Sigma Lithium” or the “Company”)
(NASDAQ: SGML, TSXV: SGML , BVMF: S2GM34), a leading global lithium producer dedicated to powering the
next generation of electric vehicles with carbon neutral, socially and environmentally responsibly sourced Triple
Zero Green Lithium, is pleased to announce that it continues to add experienced top talent to senior leadership
roles as it becomes one of the world’s largest lithium producers, consolidating its leading sustainability position.
Sigma Lithium is honored to announce that Matthew DeYoe is joining the Company from Bank of America,
where he was the leading coverage research director for lithium and chemical companies over the past four
years.
Matthew will join as the Company’s Executive Vice President for Corporate Affairs and Strategic
Development, based in the United States. This appointment seeks to enhance Sigma Lithium’s direct personal
interface with global investors, maximizing the value of Sigma Lithium’s common shares listing on the Nasdaq
Stock Exchange, where the Company’s public float currently trades. Matthew will start his new position
effective immediately.
Matthew will also advise the management team on its growth strategy and new market opportunities. Prior to
Bank of America, Matthew held positions on the buy-side at hedge funds where he specialized in chemical,
lithium, and energy investments. Matthew holds a Bachelor of Science degree in Business Administration
from Georgetown University and is a CFA charterholder.
Sigma Lithium is also augmenting its world-class environmental team by hiring Alexandre Mattos as Environmental
Director. Alexandre has 18 years of experience running every operational environmental aspect of a large
producer in metals and mining. He joins Sigma Lithium from Kinross Mineração Brazil, which has over 1,700 people
at its operating site in Brazil. He served there for over 10 years and oversaw a team of 53 full-time employees and
an additional 30 contractors.
Alexandre’s role extended across Kinross’ largest mining operations as well as its hydroelectric plants. His
oversight encompassed various critical areas, including environmental controls, biodiversity preservation, water
resources, integrated management systems, and licensing. Alexandre’s responsibilities also included work safety,
occupational hygiene, emergency preparedness and management, and critical risk mitigation. Alexandre is an
environmental engineer and holds a master’s degree in Land Planning and Environmental Management from
Universitat de Barcelona, Spain. He also holds a post graduate degree in Occupational Safety from PUC in Brazil

as well as an MBA in Environmental Studies from Fundação Getulio Vargas in Brazil. Alexandre will be based at
Sigma Lithium headquarters at Vale do Jequitinhonha, where he will work alongside Sigma’s general managers
and senior operating team.
Matthew DeYoe commented, “Sigma Lithium appealed to me as a company that is executing at a high level. The
team at Sigma has delivered on its commitments time and again. With a low cost position and significant opportunity
for growth, it is easy to see Sigma becoming a market leader in the lithium supply chain. The company is also doing
it the right way. Sigma's commitment to sustainability and carbon neutrality make it a force for good in a world which
often sacrifices these issues.”
“I look forward to contributing my experience to Sigma Lithium's Canadian and Brazilian investor relations teams to
unlock significant shareholder value as the company has transitioned to a producer and cash flow generator,” he
continued.
Commenting on the appointment, co-Chairperson and CEO Ana Cabral said, "Sigma Lithium has delivered on
every operational and sustainability milestone on time. Matt’s willingness to lend his expertise and experience
is a testament to his belief in our execution expertise and vision to join the select group of global lithium super
majors: large scale and low-cost producers. We are now shipping over 20,000 tonnes a month, reaching over
90% of ramp up capacity, and annualizing 270,000 tonnes a year. Several of our exceptionally driven teams will
be further bolstered by the appointment of Matthew DeYoe, with his depth of knowledge and experience in the
lithium industry. He has hit the ground running, visiting our Greentech Plant and production site and teams in
Brazil this week, and will join me in Sydney, Australia at our investor event during the International Mining and
Resources Conference (IMARC).”
