Forward Looking Statements

The investor presentation referred to herein includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “will,” “expect,” “anticipate,” “believe,” “seek,” “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 also include, but are not limited to, statements regarding projections, estimates and forecasts of revenue and other financial and performance metrics, projections of market opportunity and expectations, the estimated implied enterprise value of the combined entity (the “Combined Company”) pursuant to the transactions contemplated by the Business Combination Agreement (the “Proposed Transaction”), the Company’s ability to scale and grow its business, the advantages and expected growth of the Combined Company, the Combined Company’s ability to source and retain talent, the cash position of the Combined Company following closing of the Proposed Transaction, the SPAC’s and the Company’s ability to consummate the Proposed Transaction, and expectations related to the terms and timing of the Proposed Transaction, as applicable. These statements are based on various assumptions, whether or not identified in the investor presentation referred to herein, and on the current expectations of the SPAC’s and the Company’s management and are not predictions of actual performance.

These statements involve risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to be materially different from those expressed or implied by these forward-looking statements. Although each of the SPAC and the Company believes that it has a reasonable basis for each forward-looking statement contained in the investor presentation referred to herein, each of the SPAC and the Company cautions you that these statements are based on a combination of facts and factors currently known and projections of the future, which are inherently uncertain. In addition, there will be risks and uncertainties described in the proxy statement/prospectus included in the registration statement relating to the Proposed Transaction, which is expected to be filed by the Combined Company with the Securities and Exchange Commission (the “SEC”) and other documents filed by the Combined Company or the SPAC from time to time with the SEC. These filings may identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Neither the SPAC nor the Company can assure you that the forward-looking statements in the investor presentation referred to herein will prove to be accurate. These forward-looking statements are subject to a number of risks and uncertainties, including, among others, the ability to complete the Proposed Transaction due to the failure to obtain approval from the SPAC’s shareholders or satisfy other closing conditions in the Business Combination Agreement, the occurrence of any event that could give

rise to the termination of the Business Combination Agreement, the ability to recognize the anticipated benefits of the Proposed Transaction, the amount of redemption requests made by the SPAC’s public shareholders, costs related to the Proposed Transaction, the impact of the global COVID-19 pandemic, the risk that the Proposed Transaction disrupts current plans and operations as a result of the announcement and consummation of the Proposed Transaction, the outcome of any potential litigation, government or regulatory proceedings, and other risks and uncertainties, including those to be included under the heading “Risk Factors” in the registration statement to be filed by the Combined Company with the SEC and those included under the heading “Risk Factors” in the annual report on Form 10-K for year ended December 31, 2022 of the SPAC and in its subsequent quarterly reports on Form 10-Q and other filings with the SEC. There may be additional risks that neither the SPAC nor the Company presently know or that the SPAC and the Company currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In light of the significant uncertainties in these forward-looking statements, nothing in the investor presentation referred to herein should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. The forward-looking statements in the investor presentation referred to herein represent the views of the SPAC and the Company as of the date of the investor presentation. Subsequent events and developments may cause those views to change. However, while the SPAC and the Company may update these forward-looking statements in the future, there is no current intention to do so, except to the extent required by applicable law. You should, therefore, not rely on these forward-looking statements as representing the views of the SPAC or the Company as of any date subsequent to the date of the investor presentation referred to herein. Except as may be required by law, neither the SPAC nor the Company undertakes any duty to update these forward-looking statements.

Additional Information and Where to Find It

In connection with the Proposed Transaction, the SPAC and the Company intend to cause a registration statement on Form F-4 to be filed with the SEC, which will include a proxy statement to be distributed to the SPAC’s shareholders in connection with the SPAC’s solicitation for proxies for the vote by the SPAC’s shareholders in connection with the Proposed Transaction and other matters as described in the registration statement, as well as a prospectus relating to the Company’s securities to be issued in connection with the Proposed Transaction. The SPAC’s shareholders and other interested persons are advised to read, once available, the preliminary proxy statement/prospectus and any amendments thereto and, once available, the definitive proxy statement/prospectus, in connection with the SPAC’s solicitation of proxies for its special meeting of shareholders to be held to approve, among other things, the Proposed Transaction, because these documents will contain important information about the SPAC, the Company and the Proposed Transaction. After the registration statement is filed and declared effective, the SPAC will mail a definitive proxy statement and other relevant documents to its shareholders as of the record date to be established for voting on the Proposed Transaction.
