Technical commentary

The Company recorded higher revenue ($11.2m vs. $10.3m in September) and average operating hashrate (5,571 PH/s vs. 5,554 PH/s in September). The decrease in Bitcoin mined (376 vs. 390 in September) was primarily attributable to an increase in network difficulty. The increase in electricity costs per Bitcoin ($15.6k vs. $13.7k in September) was attributable to lower energy trading proceeds at Childress as well as an increase in network difficulty compared to September, noting the Company retains flexibility to reduce future power costs through adjusting miner output in response to changes in mining economics.
