Cyxtera Results Presentation Deck

Disclaimer This presentation includes "forward-looking statements" within the meaning of the federal securities laws. Any statement that is not a statement of historical fact is a forward looking statement. Forward-looking statements generally are identified by words such as "expects," "will," "projected," "continue," "increase," and/or similar expressions that concern Cyxtera's strategy, plans or intentions, but the absence of these words does not mean that a statement is not forward-looking. The forward- looking statements contained in this presentation are subject to a number of risks and uncertainties that could cause actual results and conditions to differ materially from those indicated in the forward-looking statements, including, but not limited to, the effects of the COVID-19 pandemic on Cyxtera's business or future results; the ability to access external sources of capital on favorable terms or at all, which could limit Cyxtera's ability to execute its business and growth strategies; the ability to compete successfully against current and future competitors; Cyxtera's fluctuating operating results; Cyxtera's ability to continue to develop, acquire, market and provide new offerings or enhancements to existing offerings that meet customer requirements and differentiate it from its competitors; the requirements of being a public company, including maintaining adequate internal control over financial and management systems; Cyxtera's ability to lease available space to existing or new customers, which could be constrained by its ability to provide sufficient electrical power; Cyxtera's ability to manage its growth; volatility of the market price of Cyxtera's Class A common stock; and Cyxtera's ability to use its United States federal and state net operating losses to offset future United States federal and applicable state taxable income may be subject to certain limitations which could accelerate or permanently increase taxes owed. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the "Risk Factors" section of the definitive proxy statement related to the business combination filed by Starboard Value Acquisition Corp. and other documents filed by Cyxtera from time to time with the SEC. There may be additional risks that Cyxtera does not presently know or that it currently believes are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Cyxtera's expectations, plans or forecasts of future events and views as of the date of this presentation. Accordingly, you should not place undue reliance upon any such forward-looking statements in this presentation. Neither Cyxtera nor any of its affiliates assume any obligation to update this presentation, except as required by law. This presentation also contains estimates and other statistical data made by independent parties and by Cyxtera relating to market size and growth and other data about Cyxtera's industry and estimated total addressable market. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. Neither Cyxtera nor any other person makes any representation as to the accuracy or completeness of such data or undertakes any obligation to update such data after the date of this presentation. This presentation contains certain financial measures that are not calculated pursuant to U.S. generally accepted accounting principles ("GAAP"). These non-GAAP financial measures are in addition to, and not as a substitute for or superior to measures of financial performance prepared in accordance with GAAP. There are a number of limitations related to the use of these non-GAAP financial measures versus their nearest GAAP equivalents. For example, other companies may calculate non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. Reference the Appendix for a reconciliation of non-GAAP financial measures to the nearest GAAP measure. Cyxtera 2
