Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

These statements are statements that are not historical facts, and are based on our management’s current view and estimates 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 condition and operating results.

Statements regarding the potential outcome of legal and administrative proceedings, the implementation of principal operating and financing strategies and capital expenditure plans, the direction of future operations and the factors or trends affecting our financial condition, liquidity or results of operations are examples of forward-looking statements. Such statements reflect the 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 and factors, including general economic and market conditions, industry conditions, and operating factors. Any changes in such 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.
