Forward-Looking Statements This presentation may contain “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. The expectations, estimates and projections of the businesses of MBAC or Syniverse may differ from their actual results and consequently you should not rely on these forward-looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “would,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” and similar expressions are intended to identify such forward-looking statements. These forward-looking statements include, without limitation, expectations with respect to future performance of MBAC and Syniverse and anticipated financial impacts of the proposed transaction, the satisfaction of the closing conditions to the proposed transaction and the timing of the completion of the proposed transaction. These forward-looking statements are not guarantees of future performance, conditions, or results, and involve significant risks and uncertainties that could cause the actual results to differ materially from the expected results. Most of these factors are outside of the control of MBAC and Syniverse and are difficult to predict. Factors that may cause such differences include, but are not limited to: (1) the inability to complete the transactions contemplated by the agreement and plan of merger with respect to the proposed transaction (the “Merger Agreement”), including due to failure to obtain approval of the stockholders of MBAC or other conditions to closing in the Merger Agreement; (2) the outcome of any legal proceedings that may be instituted against the parties following announcement of the Merger Agreement and the proposed transactions contemplated thereby; (3) the ability to recognize the anticipated benefits of the proposed business combination, which may be affected by, among other things, competition, the ability of the post-combination company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees; (4) the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement and the proposed transactions contemplated thereby; (5) risks related to the uncertainty of the projected financial information with respect to Syniverse; (6) the inability to obtain or maintain the listing of the post-acquisition company’s Class A Stock and public warrants on the NYSE following the proposed business combination; (7) risks related to the post-combination company’s ability to raise financing in the future; (8) the post-combination company’s success in retaining or recruiting, or changes required in, our officers, key employees or directors following the proposed business combination; (9) our directors and officers potentially having conflicts of interest with our business or in approving the proposed business combination; (10) intense competition and competitive pressures from other companies in the industry in which the post-combination company will operate; (11) the business, operations and financial performance of Syniverse, including market conditions and global and economic factors beyond Syniverse’s control; (12) the effect of legal, tax and regulatory changes; (13) the receipt by MBAC or Syniverse of an unsolicited offer from another party for an alternative business transaction that could interfere with the proposed business combination; (14) the risk that the proposed business combination disrupts current plans and operations of MBAC or Syniverse as a result of the announcement and consummation of the transactions described herein; (15) costs related to the proposed business combination; (16) changes in applicable laws or regulations; (17) the possibility that MBAC or Syniverse may be adversely affected by other economic, business, and/or competitive factors; (18) the amount of redemption requests made by MBAC’s public stockholders; (19) the impact of the continuing COVID-19 pandemic on MBAC, Syniverse and Syniverse’s projected results of operations, financial performance or other financial metrics or on any of the foregoing risks; and (20) other risks and uncertainties disclosed in MBAC’s preliminary proxy statement, including those under “Risk Factors,” and other documents filed or to be filed with the SEC by MBAC. MBAC and Syniverse caution that the foregoing list of factors is not exclusive. You should not place undue reliance upon any forward-looking statements, which speak only as of the date made. Syniverse and MBAC do not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in their expectations or any change in events, conditions or circumstances on which any such statement is based. This presentation also contains certain non-GAAP financial measures. These non-GAAP financial measures are in addition to, and not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP. Reconciliations between non-GAAP financial measures and GAAP financial measures are provided in the Appendices of this presentation. Due to rounding, the numbers and percentages reported in this presentation may not sum to totals or quarterly amounts.
