These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause System1's actual financial results or operating performance to be materially different from those expressed or implied by these forward-looking statements. Readers or users of this presentation should evaluate the risk factors summarized below, which summary list is not exclusive. Readers or users of this presentation should also carefully review the “Risk Factors” and other information included in our registration statements on Form S-4 (including the related proxy statement/prospectus) with respect to the Business Combination with Trebia and on Form S-1, each filed with the Securities and Exchange Commission (the “SEC ”), as well as System1’s Form 10-K, Form 10-Q, Form 8-K and other reports filed with the SEC from time to time. Please refer to the SEC filings for additional information regarding the risks and other factors that may impact System1’s business, prospects, financial results and operating performance following completion of the business combination. Such risks, uncertainties and assumptions include, but are not limited to: (1) our ability to grow and manage growth profitably, and retain its key employees; (2) our ability to acquire businesses on acceptable terms and to successfully integrate and recognize anticipated synergies from acquired businesses; (3) use of cash and other available liquidity to grow and invest in our businesses; (4) continued growth of our digital media and subscription offerings; (5) international growth; (6) our ability to develop or introduce new products, services, features and technologies; (7) our liquidity and our ability to repay or refinance our outstanding indebtedness; (8) technology, platform and infrastructure systems capacity, coverage, reliability and security; (9) changes in or recent developments related to applicable laws or regulations (including those concerning data security, consumer privacy and/or information sharing); (10) the possibility that we may be adversely affected by other economic, business, and/or competitive factors; and (11) the impact of Covid-19 and other political or societal developments. The foregoing list of factors is not exclusive. 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. System1's independent auditors have not 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, do not express an opinion or provide any other form of assurance with respect thereto for the purpose of this presentation. 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. This presentation contains certain financial forecasts (or guidance) with respect to the System1’s projected financial results. System1’s independent auditors have not 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.

Disclaimer (Continued) 2 Explanatory Note For financial reporting purposes, S1 Holdco has been determined to be the accounting predecessor and therefore its financial results are presented for all periods prior to the Business Combination with Trebia. In order to present comparable financial information, year-over-year comparisons of financial results against the second quarter of 2021 combine the unaudited financial results of Protected with the unaudited financial results of S1 Holdco for the second quarter of 2021. The Company believes it is important to provide these combined financial results for investors and other stakeholders to properly evaluate its performance in 2022 relative to comparable information provided in prior periods. Please refer to the tables at the end of this release for a reconciliation of the combined financial results as presented herein to the individual financial results of S1 Holdco, Protected and System1, respectively, for the respective successor and predecessor periods. 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. All references to third-party trademarks are for identification purposes only and shall be considered nominative fair use under applicable trademark law. Non-GAAP Measures: Adjusted Gross Profit and Adjusted EBITDA Adjusted Gross Profit and Adjusted EBITDA are non-GAAP financial measures and represent key metrics used by System1’s management and board of directors to measure the operational strength and performance of its business, to establish budgets, and to develop operational goals for managing its business. Adjusted Gross Profit (Loss) is defined as Revenue less cost of revenue (exclusive of depreciation and amortization related to cost of revenue). Adjusted EBITDA is defined as net income (loss) before interest expense, income taxes, depreciation and amortization expense, stock-based compensation expenses, deferred compensation, management fees, minority interest expense, restructuring charges, impairment and certain discrete items impacting a particular segment’s results in a particular period. System1 believes Adjusted Gross Profit and Adjusted EBITDA are relevant and useful metrics for investors because it allows investors to view performance in a manner similar to the method used by management. There are limitations on the use of Adjusted Gross Profit and Adjusted EBITDA and it may not be comparable to similarly titled measures of other companies. Other companies, including companies in System1’s industry, may calculate non- GAAP financial measures differently than System1 does, limiting the usefulness of those measures for comparative purposes. Adjusted Gross Profit should not be considered a substitute for revenue. Adjusted EBITDA should not be considered a substitute for income (loss) from operations, net income (loss), or net income (loss) attributable to System1 on a consolidated basis that System1 reports in accordance with GAAP. Although System1 uses Adjusted Gross Profit and Adjusted EBITDA as financial measures to assess the performance of its business, such use is limited because it does not include certain costs necessary to operate System1’s business. System1’s presentation of Adjusted Gross Profit and Adjusted EBITDA should not be construed as indications that its future results will be unaffected by unusual or nonrecurring items. The Company is not able to reasonably reconcile Adjusted Gross Profit to Gross Profit and Adjusted EBITDA to net income, its nearest GAAP metrics, in its guidance for future periods due to uncertainties regarding purchase accounting, stock-based compensation, taxes and other potential adjustments. Use of Projections This presentation contains certain financial forecasts (or guidance) with respect to the System1’s projected financial results. System1’s independent auditors have not 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. This guidance 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 set forth 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 actually 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, including the proxy statement/prospectus, relating to its recently completed business combination with Trebia.
