Ana Cabral, CEO commented: "We are delighted with the overwhelming interest in our business from some of the most admired companies in the battery materials and electric vehicles industries globally, including automakers and battery manufacturers. We are also honored with the direct engagement of C-level executives and board members from the consortiums with our leadership during this strategic process, significantly strengthening our relationships with global leaders and key decision makers of our industry."

Lucas Melo, Chair of the Audit Committee complemented: "Brazil is building thriving and globalized lithium mining and materials industries: welcoming strategic partners from all over the world. The country's lithium industry has already received investments from companies headquartered in China, the United States, Canada, Australia and the United Kingdom. The Singaporean listing of Sigma Brazil aims to maximize value for all shareholders of Sigma Lithium by leveling the playing field across negotiating parties."

Cesar Chicayban, Lead Independent Board Member added: "As the Company is a completely ramped up producer, we can evaluate strategic alternatives from a position of maximum flexibility despite the current lithium cycle downturn. Sigma is one of the largest and lowest cost producers in the industry and reached Net Zero, achieving a key competitive advantage for the European Battery Passport. Therefore, Sigma Lithium in parallel to its strategic review, has been laser focused on consolidating its position as one of the majors by concluding the detailed engineering for its production capacity expansion plans."
