System1 SPAC Presentation Deck

Disclaimer (Continued) Should one or more of these risks or uncertainties materialize, they could cause our actual results to differ materially from any forward-looking statements contained in this presentation. Neither Trebia's nor System1's independent auditors have audited, reviewed, compiled or performed any procedures with respect to the forward-looking statements 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 purpose of this presentation. Trebia and System1 will not undertake any obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise. You should not take any statement regarding past trends or activities as a representation that such trends or activities will continue in the future. Accordingly, you should not put undue reliance on these statements. This presentation is not intended to constitute, and should not be construed as, investment advice. An investment in Trebia is not an investment in any of our founders' or sponsors' past investments or companies or any funds affiliated with any of the foregoing. The historical results of these investments are not indicative of future performance of Trebia (including after the closing of the proposed business combination), which may differ materially from the performance of the founders or sponsors past investments, companies or affiliated funds. Trademarks This presentation may contain trademarks, service marks, trade names and copyrights of other companies, which are the property of their respective owners. Solely for convenience, some of the trademarks, service marks, trade names and copyrights referred to in this presentation may be listed without the TM, SM or Ⓒ symbols, but System1 will assert, to the fullest extent under applicable law, the rights of the applicable owners, if any, to these trademarks, service marks, trade names and copyrights. Use of Non-GAAP Financial Measures This presentation includes non-GAAP financial measures, including Pro Forma Adj. EBITDA. Trebia and System1 believe that these non-GAAP measures are useful to investors for two principal reasons: (1) these measures may assist investors in comparing performance over various reporting periods on a consistent basis by removing from operating results the impact of items that do not reflect core operating performance; and (2) these measures are used by System1's management and board of directors to assess its performance and may (subject to the limitations described below) enable investors to compare the performance of System1 to its competitors. Trebia and System1 believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends. These non-GAAP measures should not be considered in isolation from, or as an alternative to, financial measures determined in accordance with GAAP. Other companies may calculate these non-GAAP measures differently or use different non- GAAP measures financial from those used in this presentation, and therefore such measures may not be directly comparable to similarly titled measures of other companies. For reconciliation of these non-GAAP financial measures used in this presentation, see "Net Income to Pro Forma Adj. EBITDA" included in the Appendix at the end of this presentation, as well as information included in the registration statement on Form S- 4 relating to the proposed business combination. Use of Projections This presentation contains financial forecasts with respect to the System1's projected financial results. Neither Trebia's nor System1's independent auditors have audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this presentation, and accordingly, they did not express an opinion or provide any other form of assurance with respect thereto for the purpose of this presentation. These projections should not be relied upon as being necessarily indicative of future results. The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of System1 or that actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved. You should review this information together with System1's historical information, as well as information included in the registration statement on Form S-4 relating to the proposed business combination. Important Information About the Proposed Business Combination and Where to Find It In connection with the proposed business combination, a registration statement on Form S-4 was filed by Trebia with the U.S. Securities and Exchange Commission ("SEC") that will be distributed to holders of Trebia ordinary shares in connection with Trebia's solicitation for proxies for the vote by Trebia's shareholders in connection with the proposed business combination with System1 and other matters as described in the registration statement on Form S-4. Trebia and System1 urge investors, shareholders and other interested persons to read, when available, the effective registration statement on Form S-4, including the proxy statement/prospectus, as well as other documents filed with the SEC in connection with the proposed business combination, as these materials will contain important information about Trebia, System1 and the proposed business combination. Such persons can also read Trebia's final prospectus, as amended, dated June 16, 2020 (SEC File No. 333-238824), which was filed with the SEC on June 18, 2020, for a description of the security holdings of Trebia's officers and directors and their respective interests as security holders in the consummation of the proposed business combination. After the registration statement on Form S-4 has been declared effective, the definitive proxy statement/prospectus will be mailed to Trebia's shareholders as of a record date to be established for voting on the proposed business combination. Shareholders will also be able to obtain copies of such documents, without charge, once available, at the SEC's website at www.sec.gov, or by directing a request to: Trebia Acquisition Corp., 41 Madison Avenue, Suite 2020, New York, NY 10010.
