#1Cyxtera Q2 2022 Earnings Supplemental Data August 11, 2022 Cyxtera#2Disclaimer This presentation includes "forward-looking statements" within the meaning of the federal securities laws. Forward-looking statements contained in this presentation include statements concerning Cyxtera's estimated financial performance for 2022. Because forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of Cyxtera's control. Actual results and conditions (financial or otherwise) may differ materially from those indicated in the forward-looking statements. These forward-looking statements 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, including supply chain disruptions; increases in interest rates; fluctuations in energy prices; fluctuations in foreign currency exchange rates in the markets in which Cyxtera operates internationally; inflation; prolonged power outages, shortages or capacity constraints; physical and electronic security breaches and cyber-attacks, which could disrupt Cyxtera's operations; any failure of Cyxtera's physical infrastructure or negative impact on its ability to provide its services, or damage to customer infrastructure within its data centers; inadequate or inaccurate external and internal information, including budget and planning data, which could lead to inaccurate financial forecasts and inappropriate financial decisions; Cyxtera's fluctuating operating results; Cyxtera's ability to maintain its credit ratings; Cyxtera's government contracts, which are subject to early termination, audits, investigations, sanctions and penalties; Cyxtera's reliance on third parties to provide internet connectivity to its data centers; the incurrence of goodwill and other intangible asset impairment charges, or impairment charges to Cyxtera's property and equipment, which could result in a significant reduction to its earnings; Cyxtera's 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 requirements of being a public company, including maintaining adequate internal controls over financial and management systems; Cyxtera's ability to manage its growth; volatility of the market price of Cyxtera's Class A common stock; future sales, or the perception of future sales, of Cyxtera Class A common stock by existing securityholders in the public market, which could cause the market price for Cyxtera's Class A common stock to decline; 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 that could accelerate or permanently increase taxes owed. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the "Risk Factors" disclosed in Cyxtera's filings with the Securities and Exchange Commission ("SEC") from time to time. There may be additional risks that Cyxtera does not presently know or that it currently believes are im material 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. Statement Regarding Non-GAAP Financial Measures This presentation contains Transaction Adjusted EBITDA, which is a supplemental measure that is not required by, or presented in accordance with, accounting principles generally accepted in the United States ("GAAP"). Transaction Adjusted EBITDA represents the measure of EBITDA disclosed to Starboard Value Acquisition Corp ("SVAC") in connection with its consideration of the business combination transaction between SVAC and Cyxtera. Cyxtera defines Transaction Adjusted EBITDA as net income (loss) before the following items: depreciation and amortization, interest and other expenses, net, income tax expense (benefit), equity-based compensation, straight-line rent adjustment, amortization of favorable / unfavorable leasehold interest & asset retirement obligation accretion, stand-up separation & other, restructuring costs & other, and change in fair value of warrant liabilities. As a Non-GAAP financial measure, Transaction Adjusted EBITDA excludes items that are significant in understanding and assessing Cyxtera's financial results or position. Therefore, this measure should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. You should be aware that Cyxtera's presentation of this measure may not be comparable to similarly-titled measures used by other companies. Refer to the Appendix to this presentation, which includes a reconciliation of the non-GAAP financial measures included in this presentation to the most directly comparable GAAP financial measures. This presentation also includes certain projections of non-GAAP financial measures concerning Cyxtera. Due to the high variability and difficulty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, Cyxtera is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measures without unreasonable effort. Consequently, no disclosure of estimated comparable GAAP measures is included and no reconciliation of the forward-looking non-GAAP financial measures is included.
