Factors that could cause actual results to differ materially from those described in such forward-looking information include, but are not limited to: market and other conditions, continued effects of the COVID-19 pandemic may have a material adverse effect on the Company’s performance as supply chains are disrupted and prevent the Company from operating its assets; a decrease in cryptocurrency pricing, volume of transaction activity or generally, the profitability of cryptocurrency mining; further improvements to profitability and efficiency may not be realized; the digital currency market; the Company’s ability to successfully mine digital currency on the cloud; the Company may not be able to profitably liquidate its current digital currency inventory, or at all; a decline in digital currency prices may have a significant negative impact on the Company’s operations; the volatility of digital currency prices; the availability of electricity at prevailing rates and on a continuous basis; the adequacy and security of custody for coins maintained in inventory; and, other related risks as more fully set out in the Annual Information Form of the Company and other documents disclosed under the Company’s filings at www.sedar.com.
