Rogerio Marchini Appointed Executive Vice President of Corporate Finance and CFO

Sigma Lithium is also pleased to announce the appointment of Rogerio Marchini to its senior leadership, as the new Executive Vice President of Corporate Finance and Chief Financial Officer ("CFO"). Rogerio is a prominent executive in Brazil, with a deep experience of 24+ years in finance. For the last 7 years Rogerio was the CFO of Origo, a private equity portfolio company of TPG International in the energy transition space. Here, he led the 40-person team through business transformation from start-up to final monetization. Rogerio also served as Director of Finance at Embraer where he worked for 13 years (the leading regional aircraft manufacturer and exporter).

Rogerio will be supported by the current high caliber team of finance executives, including Caio Araujo, who remains at the Company as a Director of the Controller's Office and Felipe Peres, who led Sigma Lithium to its Nasdaq listing and was on medical leave in 2023, having returned to the Company as Director of Site Administration and Finance. Felipe will also be leading procurement and controls for the construction of the Phase 2 expansion of the Greentech Lithium Processing Plant, which will double Company capacity to 520,000t of Quintuple Zero Green Lithium (equivalent to approximately 80,000t of LCE).

CEO and Co-Chairperson Ana Cabral notes: "We are very pleased with our commercial partnership and deepening relationship with Mitsubishi. Mitsubishi's market visibility, as a Japanese industrial conglomerate keiretsu (carmaker, commercial bank, trading) has helped Sigma Lithium successfully navigate the pronounced seasonality of demand and price swings displayed by the lithium market this summer," she concluded.

"We are also delighted to welcome Rogerio Marchini to our senior leadership. Rogerio is a tremendous addition to our finance team, a seasoned Brazilian executive with significant experience in comparable companies encompassing key aspects of our business: energy transition and global exporting. In a testament to our culture of excellence and teamwork, Rogerio will be supported by two former Sigma Lithium CFOs who have been deployed to lead critical areas within the finance department. Rogerio's appointment further bolsters the strength of our finance team."
