Disclaimer This presentation has been prepared by GlobalFoundries Inc. (the "Company") solely for informational purposes and is to be maintained in strict confidence. Neither the information contained in this presentation, nor any further information made available by the Company or any of its affiliates or employees, directors, representatives, officers, agents or advisers, in connection with this presentation will form the basis of or be construed as a contract or any other legal obligation. This presentation does not give and should not be construed as giving investment, legal, tax or other advice. By receiving these materials and/or attending this presentation, you agree to, or cause your representatives and advisors to, use the information contained herein only to evaluate the Company and for no other purpose. This presentation shall not constitute an offer to sell or the solicitation of an offer to buy securities, nor shall there be any sale of securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction. This presentation and the accompanying oral presentation include express and implied "forward-looking statements," including but not limited to, statements regarding our financial outlook, product development, business strategy and plans, and market trends, opportunities and positioning. Forward-looking statements are based on our management's beliefs and assumptions and on information currently available to our management. These forward-looking statements are based on current expectations, estimates, forecasts and projections. Words such as "expect," "anticipate," "should," "believe," "hope," "target," "project," "goals," "estimate," "potential," "predict," "may," "will," "might," "could," "intend," "shall" and variations of these terms and similar expressions are intended to identify these forward-looking statements, although not all forward-looking statements contain these identifying words. Forward-looking statements are subject to a number of risks and uncertainties, many of which involve factors or circumstances that are beyond our control. For example, our business could be impacted by the COVID-19 pandemic and actions taken in response to it; the market for our products may develop more slowly than expected or than it has in the past; our operating results may fluctuate more than expected; there may be significant fluctuations in our results of operations and cash flows related to our revenue recognition or otherwise; a network or data security incident that allows unauthorized access to our network or data or our customers' data could damage our reputation; we could experience interruptions or performance problems associated with our technology, including a service outage; and global economic conditions could deteriorate. For further discussion of potential risks and uncertainties, please see "Risk Factors" contained in our filings with the U.S. Securities and Exchange Commission. It is not possible for us to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results or outcomes to differ materially from those contained in any forward-looking statements we may make. Moreover, we operate in a competitive and rapidly changing market, and new risks may emerge from time to time. You should not rely upon forward-looking statements as predictions of future events. These statements are based on our historical performance and on our current plans, estimates and projections in light of information currently available to us, and therefore you should not place undue reliance on them. Although we believe that the expectations reflected in our statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances described in the forward- looking statements will be achieved or occur. Recipients are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date such statements are made and should not be construed as statements of fact. Except to the extent required by federal securities laws, we undertake no obligation to update any information or any forward-looking statements as a result of new information, subsequent events, or any other circumstances after the date hereof, or to reflect the occurrence of unanticipated events. This presentation and the accompanying oral presentation also contain estimates and other statistical data published by independent parties and by us relating to market size and growth and other data about our industry and business. These estimates and data involve a number of assumptions and limitations, and you are cautioned not to give undue weight to them. We have not independently verified the industry data generated by independent parties and contained in this presentation and, accordingly, we cannot guarantee their accuracy or completeness. In addition, projections, assumptions, and estimates of our future performance and the future performance of the markets in which we compete are necessarily subject to a high degree of uncertainty and risk.
