This presentation has been prepared by Atento. The information contained in this presentation is for informational purposes only. The information contained in this presentation is not investment or financial product advice and is not intended to be used as the basis for making an investment decision. This presentation has been prepared without taking into account the investment objectives, financial situation or particular needs of any particular person.

This presentation contains forward-looking statements within the meaning of the U.S. federal securities laws, that are subject to risks and uncertainties. All statements other than statements of historical fact included in this presentation are forward-looking statements. Forward-looking statements give our current expectations and projections relating to our financial condition, results of operations, plans, objectives, future performance and business. Forward-looking statements can be identified by the use of words such as "may," "should," "expects," "plans," "anticipates," "believes," "estimates," "predicts," "intends," "continue“, the negative thereof and other words and terms of similar meaning in connection with any discussion of the timing or nature of future operating or financial performance or other events. These forward-looking statements are based on assumptions that we have made in light of our industry experience and on our perceptions of historical trends, current conditions, expected future developments and other factors we believe are appropriate under the circumstances. As you consider this presentation, you should understand that these statements are not guarantees of performance or results. They involve risks, uncertainties (some of which are beyond our control) and assumptions. Although we believe that these forward-looking statements are based on reasonable assumptions, you should be aware that many factors could affect our actual financial results and cause them to differ materially from those anticipated in the forward-looking statements.

Because of these factors, we caution that you should not place undue reliance on any of our forward-looking statements. Further, any forward-looking statement speaks only as of the date on which it is made. New risks and uncertainties arise from time to time, and it is impossible for us to predict those events or how they may affect us. We have no duty to, and do not intend to, update or revise the forward-looking statements in this presentation after the date of this presentation.

The historical and projected financial information in this presentation includes financial information that is not presented in accordance with International Financial Reporting Standards (“IFRS”). We refer to these measures as “non-GAAP financial measurers.” The non-GAAP financial measures may not be comparable to other similarly titled measures of other companies and have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our operating results as reported under IFRS.
