Sigma Lithium Signs with a Major Brazilian Bank a US$100 Million Collateralized Bank Guarantee

Sigma Lithium Corporation has secured a significant US$100 million collateralized bank guarantee from a major Brazilian bank, marking a crucial milestone in the company's expansion strategy. The financing arrangement is fully collateralized by the company's clients through a combination of corporate guarantees, letters of credit, and export receivables, demonstrating strong customer support and confidence in Sigma Lithium's business model.

The bank guarantee will fund the construction and installation of Sigma Lithium's second Greentech Industrial Plant, which will double the company's nameplate annual production capacity from 270,000 tonnes to 520,000 tonnes of high-grade premium lithium oxide concentrate. This expansion represents a strategic move to capitalize on growing global demand for lithium materials used in battery production for energy storage applications. The new facility will replicate the environmentally sustainable technologies and processes already implemented in the company's operating Plant 1.

Sigma Lithium currently operates as the largest lithium oxide concentrate producer in the Americas, with its Grota do Cirilo operation in Brazil's Vale do Jequitinhonha region representing the world's fifth-largest industrial-mineral complex for lithium production. The company's operations have transformed the local economy, employing 13,000 people directly and indirectly while benefiting an additional 21,000 people through social inclusion programs. The region, once the second poorest in Brazil, now experiences annual growth exceeding 10%.

The financing structure reflects the strength of Sigma Lithium's customer relationships and the competitiveness of its industrialized lithium products in the global market. The expansion will further solidify the company's position in the critical minerals supply chain while continuing its commitment to environmental sustainability through the use of 100% renewable electricity, zero toxic chemicals, and complete water reuse. This development positions Sigma Lithium to meet increasing demand from battery manufacturers as the electric vehicle market continues its rapid expansion.
