Forward - Looking Statements Certain statements included in this Presentation are not historical facts but are forward - looking statements for purposes of the safe harbor provisions under the Un ited States Private Securities Litigation Reform Act of 1995. Forward - looking statements generally relate to future events or the Company’s or SPAC’s future financial or operating performance. For example, projections of future EBITDA and EBITDA Margin are forward - looking statements. In some cases, you can identify forward - looking statements by terminology such as “may”, “should”, “would”, “seem”, “expect”, “inte nd”, “will”, “estimate”, “anticipate”, “believe”, “future”, “predict”, “potential,” “forecast” or “continue”, or the negatives of these terms or variations of them or similar terminolog y, but the absence of these words does not mean that a statement is not forward - looking. Such forward - looking statements are subject to risks, uncertainties, and other factors that could cause ac tual results to differ materially from those expressed or implied by such forward looking statements. These forward - looking statements are based upon estimates and assumptions that, while considered reasonable by the Company and its management, and SPAC and its management, as the case may be, are inherently uncertain. These forward - looking statements are provided for illustrative purpose s 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. Many actual events and circumstances are beyond the control of the Company or SPAC. Factors that may cause actual results to differ materially from current expectations include, but are not limited to: (i) the occurrence of any event, change or other circumstances that could give rise to the termination of negotiations and any subsequent definitive agreements with respect to the Proposed Business Combination; (ii) the outcome of any legal proceedings that may be instituted against SPAC, the combined company or others following the announcement of the Proposed Business Combination and any definitive agreements wit h respect thereto; (iii) the inability to complete the Proposed Business Combination due to the failure to obtain approval of the stockholders of SPAC or the Company, to obtain certain governmental and regulatory approvals or to satisfy other conditions to closing, including del ays in obtaining, adverse conditions contained in, or the inability to obtain necessary regulatory approvals or complete regular reviews required to complete the Proposed Business Combination; (iv) changes to the proposed structure of the Proposed Business Combination th at may be required or appropriate as a result of applicable laws or regulations or as a condition to obtaining regulatory approval of the Proposed Business Combination; (v) the ability to meet stock exchange listing standards following the consummation of the Proposed Business Combination; (vi) th e risk that the Proposed Business Combination disrupts current plans and operations of the Company as a result of the announcement and consummation of the Proposed Business Combination; (vii) the lack of a third party valuation in determining whether or not to pursue the Proposed Business Combination; (viii) the ability to recognize the anticipated benef its of the Proposed Business Combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees; (ix) costs related to the Proposed Business Combination; (x) changes in applicable laws or regulations; (xi) the possibility that the Company or the combined company may be adversely affected by other economic, business, and/or competitive factors; (xii) inaccuracies for any reason in the estimates of expenses and profitability and projected financial information for the Company; and (xiii) other risks and uncertainties set forth in the section entitled “Risk Factors” and “Cautionary Note Regarding Forward - Looking Statements” in SPAC’s final prospectus relating to its initial public offering dated October 4, 2021. Forward - looking statements speak only as of the date they are made. Nothing in this Presentation 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. You should not place undue reliance on forward - looking statements, which speak only as of the date they are made. Neither the Company nor SPAC undertakes any duty to update these forward - looking statements. Financial Information; Non - IFRS Financial Measures The financial information and data contained in this Presentation is unaudited and does not conform to Regulation S - X promulgated under the Securities Act of 1933, as amended. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in, the registration statement to be filed by SPAC and the Company with the United States Securities and Exchange Commission (the “SEC”). This Presentation includes certain financial measures not presented in accordance with International Financial Reporting Standards (“IFRS”) including, but not limited to, EBITDA and EBITDA Margin ,. These non - IFRS measures, and other measures that are calculated using such non - IFRS measures, are in addition to, and not a substitute for or superior to, measures of financial performance prepared in accordance with IFRS and may exclude items that are significant in understanding and assessing the Company’s financial results or future performance. Therefore, these measures should not be considered in isolation or as an alternative to operating income, net income, cash flows from operations or any other profitability, liquidity or performance measures derived in accordance with IFRS. You should be aware that the Company’s presentation of these measures may not be comparable to similarly - titled measures used by other companies. The Company believes these non - IFRS measures of financial results, including on a forward - looking basis, provide useful information to management and investors regarding certain financial and business trends re lating to the Company’s financial condition and results of operations. The Company uses these non - IFRS measures for trend analyses, for budgeting and planning purposes. The Company believes that the use of these non - IFRS financial measures provides an additional tool for investors to use in evaluating projected operating results and trends in comparing the Company’s financial measures with other similar companies, many of which present similar non - IFRS financial measures to investors. These non - IFRS financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non - IFRS financial measures. The management of the Company does not consider these non - IFRS measures in isolation or as an alternative to financial measures determined in accordance with IFRS. This Presentation also includes certain projections of non - IFRS financial measures. Due to the high variability and difficulty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with so me of the excluded information not being ascertainable or accessible, the Company is unable to quantify certain amounts that would be required to be included in the most directly comparable IFRS financial measures without unreasonable effort. Consequently, no disclosure of estimated comparable IFRS measures is included and no reconciliation of the forward - looking non - IFRS financial measures is included. For the same reasons, the Company is unable to address the probable significance of the unavailable information, which could be material to future results. Use of Projections This Presentation contains financial forecasts with respect to the Company’s projected financial results for the Company’s fi sca l years 2021 through 2026. The Company’s independent auditors have not audited, reviewed, compiled or performed any procedures with respect to the proje cti ons 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. These projections constitute forward - looking information and should not be relied upon as being necessarily indicative of future results. The assumptions and estimates underlying the projected, expected or target results are inherently uncertain and are subject to a wide variety of significant business, economic, regulatory and competitive risks and uncertainties that could cause actual results to differ materially from those contained in such projections, estimates and targets. See “Forward - Looking Statements” above. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of the Company, or that actual results will n ot differ materially from those presented in the prospective financial information. The inclusion of projections, estimates and targets in this Presentation should not be regarded as an indication that the Company, SPAC, or their respective representatives, considered or consider the financial projections, estimates and targets to be a reliable prediction of future events or as a representation by any person that the results reflected in such forecasts will be achieved. Industry and Market Data The information, data and statistics contained herein are derived from various internal (including data that the Company and SPAC have internally collected) and external third - party sources. While the Company and SPAC believe such third - party information is reliable, there can be no assurance as to the accuracy or completeness of the indicated information. Neither the Company nor SPAC has independently verified the accuracy or completeness of the information provided by third party sources. No representation is made, by the Company’s or SPAC’s management, as to the reasonableness of the assumptions made within or the accuracy or completeness of any projections or modeling or any other information contained herein. Any information, data or statistics on past performance or modeling contained herein is not an indication as to future performance. The Company and SPAC assume no obligation to update the information in this presentation.

Confidential computing leverages a hardware - based trusted execution environment to protect data being processed. Protection in Transit What is Confidential Computing? Protection at Rest Protection in Use Securing data being stored by encrypting it before storing it or encrypting the device itself Securing data transmitted between networks using end - to - end encryption or by using encrypted connections Protecting data by encrypting it while it is being used in the RAM or processor for computation Holistic data security model Prevalent data security model Current security models adequately mitigate risks involved with storage and transmission of data but fail to address risks of exposing data while being processed Page 8 Emerging security models encourage the adoption of a comprehensive protection model that mitigates risks across the data lifecycle from transmission to storage and usage, which can be achieved through confidential computing
