These statements are based on various assumptions, whether or not identified in this press release, and on the current expectations of SES's and Ivanhoe's man agement and are not predictions of actual performance. These forward - looking statements are provided for illustrative purposes only and are not intended to serve as and must not be relied on by any investor as a guarantee, an assurance, a pred ict ion or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and may differ from assumptions, and such differences may be material. Many actual events and circumstances are beyond the co ntr ol of SES and Ivanhoe. These forward - looking statements are subject to a number of risks and uncertainties, including changes in domestic and foreign business, market, financial, political and legal conditions; the inability of the p art ies to successfully or timely consummate the business combination, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the business combination or that the approval of the shareholders of SES or Ivanhoe is not obtained; the failure to realize the anticipated benefits of the business combination; risks relating to the uncertainty of t he projected financial information with respect to SES; risks related to the development and commercialization of SES's battery technology and the timing and achievement of expected business milestones; the effects of competition on SES's business; the ris k that the business combination disrupts current plans and operations of Ivanhoe and SES as a result of the announcement and consummation of the business combination; the ability to recognize the anticipated benefits of the business com bination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and retain its management and key employees; risks relati ng SES’s history of no revenues and net losses; the risk that SES’s joint development agreements and other strategic alliances could be unsuccessful; risks relating to delays in the design, manufacture, regulatory approval and launch of SES’s ba ttery cells; the risk that SES may not establish supply relationships for necessary components or pay components that are more expensive than anticipated; risks relating to competition and rapid change in the electric vehicle battery market; safet y r isks posed by certain components of SES’s batteries; risks relating to machinery used in the production of SES’s batteries; risks relating to the willingness of commercial vehicle and specialty vehicle operators and consumers to adopt electric vehic les ; risks relating to SES’s intellectual property portfolio; the amount of redemption requests made by Ivanhoe's public shareholders; the ability of Ivanhoe or the combined company to issue equity or equity - linked securities or obtain debt financin g in connection with the business combination or in the future and those factors discussed in Ivanhoe's Annual Report on Form 10 - K filed with the SEC on March 31, 2021 and in Ivanhoe’s proxy statement/prospectus relating to the proposed business com bination, filed with the SEC on January 7, 2022, including those under “Risk Factors” therein, and other documents of Ivanhoe filed, or to be filed, with the SEC relating to the business combination. If any of these risks materialize or Ivanho e's or SES's assumptions prove incorrect, actual results could differ materially from the results implied by these forward - looking statements. There may be additional risks that neither Ivanhoe nor SES presently know or that Ivanhoe and SES currently belie ve are immaterial that could also cause actual results to differ from those contained in the forward - looking statements. In addition, forward - looking statements reflect Ivanhoe's and SES's expectations, plans or forecasts of future events and views onl y as of the date of this press release. Ivanhoe and SES anticipate that subsequent events and developments will cause Ivanhoe's and SES's assessments to change. However, while Ivanhoe and SES may elect to update these forward - looking statements a t some point in the future, Ivanhoe and SES specifically disclaim any obligation to do so. These forward - looking statements should not be relied upon as representing Ivanhoe's and SES's assessments as of any date subsequent to the date of th is press release. Accordingly, undue reliance should not be placed upon the forward - looking statements. USE OF PROJECTIONS This Presentation contains projected financial information with respect to SES. Such projected financial information constitu tes forward - looking information, is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such financial forecast information are inherently uncertain and are subject to a wide variety of significant technical, business, economic, competitive and other risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. See the “Forwa rd - Looking Statements” paragraph above for a description of many of such risks and uncertainties. Actual result s may differ materially from the results contemplated by the financial forecast information contained in this Presentation, and the inclus ion of such information in this Presentation should not be regarded as a representation by any person that the results reflected in such forecasts will be achieved. Neither Ivanhoe’s nor SES’s independent auditors have audited, reviewed, compil ed or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation, and accordingly, neither of them expressed an opinion or provided any other form of assurance with respect thereto for the purpos e o f this Presentation. FINANCIAL INFORMATION; NON - GAAP FINANCIAL MEASURES The financial information and data contained in this Presentation is unaudited and does not conform to Regulation S - X promulgate d under the Securities Act. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in, any proxy statement/prospectus or registration statement to be filed by Ivanhoe with the SEC. So me of the financial information and data contained in this Presentation, such as projections of Free Cash Flow and EBITDA, have not been prepared in accordance with United States generally accepted accounting principles (“GAAP”). Ivanhoe and SES be lie ve these non - GAAP measures of financial results provide useful information to management and investors relating to SES’s potential future results of operations. Management does not consider these non - GAAP measures in isolation or as an alterna tive to financial measures determined in accordance with GAAP. The principal limitation of these non - GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in SES’s financial sta tem ents. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non - GAAP financial measures. A reconciliation of no n - GAAP financial measures in this Presentation to the most directly comparable GAAP financial measures is not included, because, without unreasonable effort, SES is unable to predict with reasonable certainty the amount or timing of no n - G AAP adjustments that are used to calculate these forward - looking non - GAAP financial measures. The non - GAAP financial measures included in this Presentation may not be comparable to similarly - titled measures presented by other companies .
