This Notice to the Market may contain forward-looking statements. These statements are not historical facts, but rather are based on the
current view and estimates of the Company's management regarding future economic and other circumstances, industry conditions, financial
performance and results, including any potential or projected impact regarding the geological event in Alagoas and related legal procedures
on the Company's business, financial condition and operating results. The words “project,” “believe,” “estimate,”

businesses, employees, service providers, shareholders, investors, and other stakeholders of the Company could cause effective results
to differ significantly from current expectations. For a comprehensive description of the risks and other factors that could impact any
forward-looking statements in this document, especially the factors discussed in the sections, see the reports filed with the Brazilian
