NOTE REGARDING CERTAIN FINANCIAL MEASURES AND KEY METRICS This presentation makes reference to certain measures that are not recognized under International Financial Reporting Standards (“IFRS”) and do not have a standardized meaning prescribed by IFRS and therefore, are considered non-IFRS measures. They are not necessarily comparable to similar measures presented by other companies. Hut 8 uses non-IFRS measures including “EBITDA”, "adjusted EBITDA" and “mining profit” as additional information to complement IFRS measures by providing further understanding of Hut 8’s results of operations from management’s perspective. These non-IFRS financial performance measures are included because management has used the information to analyze the combined business performance and financial position of New Hut. These non-IFRS financial measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. In order to provide the business performance and financial position of New Hut, certain non-IFRS financial performance measures of each of Hut 8 and USBTC have been combined to show an aggregate number. Definitions and reconciliations of such measure can be found in Hut 8’s annual Management’s Discussion and Analysis for the year ended December 31, 2021, filed under its profile on SEDAR (www.sedar.com) and included in its Form 40-F filed on EDGAR (www.sec.gov).
