Forward Looking Statements

The information included herein and in any oral statements made in connection herewith include “forward-looking statements.” All statements other than statements of historical facts contained herein are forward-looking statements. Forward-looking statements may generally be identified by the use of words such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “should,” “would,” “plan,” “project,” “forecast,” “predict,” “potential,” “seem,” “seek,” “future,” “outlook,” “target” or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding estimates and forecasts of other financial and performance metrics, projections of market opportunity and market share. These statements are based on various assumptions, whether or not identified herein, and on the current expectations of the Company and BlueRiver’s management 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 prediction 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 control of the Company and BlueRiver. 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; risks relating to the uncertainty of the projected financial information with respect to the Company; the inability of the parties to successfully or timely consummate the transactions contemplated by the Merger Agreement, 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 transactions contemplated by the Merger Agreement or that the approval of the shareholders of BlueRiver or the members of the Company is not obtained; the failure to realize the anticipated benefits of the transactions contemplated by the Merger Agreement; risks related to the rollout of the Company’s business and the timing of expected business milestones; the effects of competition on the Company’s future business; the amount of redemption requests made by BlueRiver’s public shareholders; the ability of BlueRiver or the combined company to issue equity or equity-linked securities or obtain debt financing in connection with the transactions contemplated by the Merger Agreement or in the future and those factors discussed in BlueRiver’s final prospectus dated January 28, 2021, and any subsequently filed periodic or current reports, in each case, under the heading “Risk Factors,” and other documents of BlueRiver filed, or to be filed, with the SEC. If any of these risks materialize or BlueRiver’s or the Company’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 BlueRiver nor the Company presently know or that BlueRiver and the Company currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect BlueRiver’s and the Company’s expectations, plans or forecasts of future events and views as of the date hereof. BlueRiver and the Company anticipate that subsequent events and developments will cause BlueRiver’s and the Company’s assessments to change. However, while BlueRiver and the Company may elect to update these forward-looking statements at some point in the future, BlueRiver and the Company specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing BlueRiver’s and the Company’s assessments as of any date subsequent to the date hereof. Accordingly, undue reliance should not be placed upon the forward-looking statements. Additional information concerning these and other factors that may impact BlueRiver’s or the Company’s expectations and projections can be found in BlueRiver’s periodic filings with the SEC. BlueRiver’s SEC filings are available publicly on the SEC’s website at www.sec.gov.
