The earnings webcast and the Company’s latest investor presentation are available on the Company’s website here: https://investors.irisenergy.co/events-and-presentations.

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

Canal Flats has been powered by 100% renewable energy since inception.³

The project increased average monthly operating hashrate to 848 PH/s in September compared to 825 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.³

The project achieved average monthly operating hashrate of 1,579 PH/s in September compared to 1,380 PH/s in August, reflecting a full month of operations at 50MW.

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 is progressing, while the foundations are complete for the fourth data center building and erection of structural steel has commenced. The additional 30MW remains on track for completion by the end of Q4 2022.

Upon completion of the final phase at Mackenzie, 80MW of proprietary data centers are expected to power up to ~26,000 Bitmain S19j Pro and S19j miners⁴ (already under contract), generating 2.5 EH/s of operating hashrate.

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

Prince George has been powered by 100% renewable energy since inception.³

On September 27, the Company announced the full energization of 1.4 EH/s (50MW) at Prince George. The project was delivered on schedule and has been performing consistently since completion.

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

The Company is planning the build out of an initial 40MW development at the 600MW Childress site.

All required construction permits are in place and earthworks continued during the month for the substation area, the first data center building (20MW) and internal road network. Substation foundation preparations are also underway in readiness for scheduled transformer deliveries. Furthermore, purchase orders continue to be placed for key high and low voltage electrical equipment, building structures and data center equipment.

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

Iris Energy was one of the primary sponsors of the Mackenzie Senior’s Week celebrating seniors who have been recognized for their contributions and the impact they have had on the community. They were recognized through an appreciation lunch and an upcoming wine and cheese event.

A dinner was held in Childress to celebrate the successful recipients under the Company’s Childress Community Grants Program for 2022. Over US$85,000 is being awarded to 12 recipients including for the provision of safety equipment for the Little League, jackets for the disadvantaged, shade at a local playground, and chemistry class labs at a local high school. Iris Energy also joined the Childress Rotary Club (another Childress Community Grants recipient) to serve the community and partner with other local businesses.

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 2,729 PH/s in September (compared to 2,204 PH/s in August), driven by the energization of 50MW at Prince George, with total Company operating capacity exceeding 3.7 EH/s from September 27 onwards. The corresponding increase in Bitcoin mined (325 vs. 301 in August) and electricity costs ($2.9 million vs. $2.4 million in August) were also primarily attributable to full energization of Prince George during the month.

The increase in Bitcoin mined during the month (325 vs. 301 in August) was not proportional to the growth in the Company’s average operating hashrate due to an increase in the average difficulty-implied global hashrate during the period, which was also the primary driver behind the increase in the Company’s electricity costs per Bitcoin mined during the month.

Operating*	Jul-22	Aug-22	Sep-22

Avg operating hashrate (PH/s)	1,117	2,204	2,729

* 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).
