All information in this investor update is as at October 31, 2022 (unless otherwise specified) and does not give effect to the updates described in the November Updates (including the termination of the relevant hosting arrangements, the purported acceleration by the relevant lender of the Relevant Facilities or the current status and outcome of discussions with such lender in relation to the Relevant Facilities), which could have a material impact on the Company’s operating capacity, business, financial condition, cash flows and results of operations.

Canal Flats update (0.8 EH/s, 30MW) – BC, Canada

Canal Flats has been powered by 100% renewable energy since inception.⁴

The project increased average monthly operating hashrate to 862 PH/s in October compared to 848 PH/s last month. Canal Flats continued to exceed previously announced site capacity of 0.7 EH/s.

Mackenzie update (2.5 EH/s, 50MW operating / 30MW under construction) – BC, Canada

Mackenzie has been powered by 100% renewable energy since inception.⁴

The project achieved average monthly operating hashrate of 1,577 PH/s in October compared to 1,579 PH/s in September.

Construction activities at Mackenzie continue to progress for the expansion from 50MW to 80MW, which will utilize the remaining 10MW of the third data center building (20MW) and a fourth data center building (20MW).

Internal fit-out of the remaining 10MW of the third data center building (20MW) is complete. Foundations and erection of structural steel for the additional fourth data center building (20MW) is also complete, with internal fit-out ongoing. The substation and on-site electrical distribution works for the capacity increase are also underway. The additional 30MW remains on track for completion by the end of Q4 2022.

Prince George update (1.4 EH/s, 50MW) – BC, Canada

Prince George has been powered by 100% renewable energy since inception.⁴

The project achieved average monthly operating hashrate of 1,464 PH/s in October, being the first full month of operations at 50MW.

Childress update (1.3 EH/s, 40MW) – Texas, USA

Foundation and earthworks for the substation and data center area continued throughout the month in readiness for the 600MW transformer installation and first data center building structure respectively.

Key civil, data center building and substation contractors have mobilized to site and are being managed by a core group of Iris Energy employees based in Childress.

Community engagement

In Childress, Iris Energy continued to work with several of the successful recipients of the Community grants program including the 4-H Club that supports students studying Science, Technology, Engineering and Mathematics (STEM). The Texas 4-H Development Program provides inclusive opportunities to youth ages 8-18 in grades 3-12 for personal growth, community service, and fun.

Iris Energy also donated a drone to the Childress High School Athletics Department. The drone is being used by coaches of the football team to advance their training practices.

At the Mackenzie site, Iris Energy hosted eight high school students from the College of New Caledonia (CNC) Trade Discovery program. The tour provided insight into the role the electrical trades play in the construction and ongoing operations of our data centers.

Future development sites

Development works continued across additional sites in Canada, the USA and Asia-Pacific, which have the potential to support up to an additional >1GW of aggregate power capacity capable of powering growth beyond the Company’s 795MW of announced power capacity.

Technical commentary

The Company’s average operating hashrate was 3,903 PH/s in October (compared to 2,729 PH/s in September), with the increase being primarily attributable to the first full month of operations at Prince George at 50MW. The corresponding increase in Bitcoin mined (448 vs. 325 in September) and electricity costs ($4.2 million vs. $2.8 million in September) were also attributable to Prince George.

The increase in Bitcoin mined during the month (448 vs. 325 in September) was a result of the increased average operating hashrate and was partially offset by an increase in the average difficulty-implied global hashrate during the period (248 EH/s vs. 226 EH/s in September), which was also the primary driver behind the increase in the Company’s electricity costs per Bitcoin mined ($9.3k vs. $8.7k in September).

Avg operating hashrate (PH/s)	2,204	2,729	3,903

* Reflects actual recorded operating power usage and hashrate (not nameplate). Note: nameplate capacity is higher than actual operating power usage due to features of the Company’s proprietary data center design which utilizes variable speed fans to reduce power consumption during cooler months, as well as the Company maintaining a buffer within its infrastructure capacity that can be also directed to other site uses (e.g. in-house fabrication shop at Canal Flats is currently operating as Iris Energy has the advantage of saving time and costs by internally constructing certain components for its expansion sites).
