SIGMA LITHIUM RECOGNIZED FOR SUSTAINABILITY EXCELLENCE BY ITAUSA/ARAPYAU FOUNDATIONS; UPGRADES MINING OPERATIONS TARGETING HIGHER EFFICIENCY

Sigma Lithium Corporation has received significant recognition for its sustainability practices, being selected as a case study in an industry report by the ITAUSA/ARAPYAU Foundations. This recognition highlights the company's commitment to carbon neutral, socially and environmentally sustainable lithium production, positioning it favorably in an industry where ESG credentials are increasingly important for securing long-term partnerships with electric vehicle manufacturers.

The company is simultaneously implementing operational upgrades targeting higher efficiency across its mining operations. These improvements come as Sigma Lithium continues to establish itself as a leading global lithium producer focused on powering the next generation of electric vehicles. The timing of these announcements is strategic, as the lithium market faces growing scrutiny over environmental and social impacts of mining operations.

For the broader lithium sector, Sigma Lithium's sustainability recognition demonstrates that operators can achieve both commercial success and environmental stewardship. This is particularly relevant as automotive manufacturers and battery companies increasingly require ESG-compliant supply chains. The operational efficiency upgrades also reflect the industry's ongoing focus on optimizing production costs and throughput to meet growing demand from the electric vehicle transition.

The recognition from respected Brazilian foundations adds credibility to Sigma Lithium's sustainability claims and may provide competitive advantages in securing offtake agreements with environmentally conscious customers. As the lithium market matures, companies with strong sustainability credentials and efficient operations are likely to command premium valuations and preferred supplier status in the critical minerals supply chain.
