This press release includes "forward-looking statements " within the meaning of the "safe harbor" provisions of the United States Private Securities Litigation Reform Act of 1995, particularly any statements or materials regarding System1's future results or "guidance" for fiscal year 2022. Forward-looking statements include, but are not limited to, statements regarding System1 or its management team's expectations, hopes, beliefs, intentions or strategies regarding the future. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words "anticipate," "believe," "continue," "could," "estimate," "expect," "intend," "may," "might," "plan," "possible," "potential," "predict," "project," "should," "would" and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.

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 press release 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 Acquisition Corp. and on Form S-1 filed with the Securities and Exchange Commission (the "SEC "), as well as System1's Form 10-K, 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 press release. 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 press release, and accordingly, do not express an opinion or provide any other form of assurance with respect thereto for the purpose of this press release. 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.

Non-GAAP Measure Adjusted EBITDA

Adjusted EBITDA is a non-GAAP financial measure and represents a key metric 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 EBITDA is defined as net income (loss) before interest expense, income taxes, depreciation and amortization expense, 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 EBITDA is relevant and useful information 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 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 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 EBITDA as a financial measure 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 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 EBITDA to net income, its nearest GAAP metric, in its guidance for future periods due to uncertainties regarding purchase accounting, stock-based compensation, taxes and other potential adjustments
