of future economic and other circumstances, industry conditions, company performance and financial results, including any potential
or projected impact of the geological event in Alagoas and related legal proceedings and of COVID-19 on our business, financial

current views of our management and are subject to a number of risks and uncertainties, many of which are outside of the our control.
There is no guarantee that the expected events, trends or results will actually occur. The statements are based on many assumptions

assumptions or factors, including the projected impact of the geological event in Alagoas and related legal proceedings and the
unprecedented impact of COVID-19 pandemic on our business, employees, service providers, stockholders, investors and other stakeholders,
could cause actual results to differ materially from current expectations. Please refer to our annual report on Form 20-F for the
year ended December 31, 2019 filed with the SEC, as well as any subsequent filings made by us pursuant to the Exchange Act, each
of which is available on the SEC&rsquo;s website (www.sec.gov), for a full discussion of the risks and other factors that may impact
