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 relating 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 some 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 urreasonable 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 fiscal years 2021 through 2026. The Company's independent auditors have not audited, reviewed, compiled or performed any procedures with respect to the projections 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 not 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.
