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).
