Technical commentary

The Company’s average operating hashrate was 5,510 PH/s in May (compared to 3,965 PH/s in April), with the increase primarily attributable to the installation of additional miners across our sites (including the first full month of operations at Childress). The increase in Bitcoin mined (508 vs. 319 in April) and electricity costs ($6.1 million vs. $4.2 million in April) were also primarily attributable to the increase in installed miners. Electricity costs per Bitcoin were $11.9k in May (compared to $12.6k in April), with the decrease primarily attributable to an increase in network transaction fees.

1 All timing references in this investor update are to calendar months, in each case unless otherwise specified.2 Bitcoin and Bitcoin mined in this investor update are presented in accordance with our revenue recognition policy which is determined on a Bitcoin received basis (post deduction of mining pool fees as applicable).3 Reflects USD equivalent, unaudited preliminary cash, cash equivalents and term deposits as of April 30, 2023.4 Assumes ~0.1 EH/s from optimization of current operating capacity plus ~0.9 EH/s from purchase of high efficiency Bitmain S19 XP miners. Additional miners have not yet been purchased and we will continue to monitor the market for purchase opportunities.5 Currently approximately 97% directly from renewable energy sources; approximately 3% from purchase of RECs.6 Comprises actual power usage for Canal Flats, Mackenzie, Prince George and Childress. Childress has been powered by 100% renewable energy since inception via the purchase of RECs.7 The Company’s unadjusted electricity costs per Bitcoin mined were elevated in March and April primarily due to excess demand charges for our BC sites attributable to unutilized power capacity. The adjusted electricity costs per Bitcoin mined excludes such excess demand charges (i.e. assumes demand charges based on average demand for the period).8 Includes mix of lower efficiency hardware, which is estimated to represent less than 1% of the operating 5.6 EH/s.9 Includes S19 XP hardware which is estimated to represent ~25% of hashrate pending deployment or in transit. Excludes some lower efficiency hardware.10 Reflects estimated hashrate capacity by site assuming full utilization of available data center capacity with Bitmain S19j Pro miners.11 Assumes installation of high efficiency Bitmain S19 XP miners. Additional miners have not yet been purchased and we will continue to monitor the market for purchase opportunities.
