Corporate update

Operating capacity increased by 79% to 3.1 EH/s
Iris Energy is pleased to advise that it has increased its operating hashrate from 1.7 EH/s⁴ to a current level of 3.1 EH/s (as part of the Company’s recently announced increase in self-mining capacity to 5.5 EH/s).

An additional 2.0 EH/s of miners have been delivered and are pending installation, while the remaining 0.4 EH/s of miners are in transit and scheduled to be delivered imminently.

160MW of data centers (supporting ~4.9 EH/s) is available immediately, with commissioning of the first 20MW at Childress (supporting the remaining ~0.6 EH/s) expected to commence in the coming weeks.

Share acquisition by director
The Company advises that between March 13, 2023, and April 5, 2023, an entity affiliated with Mr. Michael Alfred, a director on the Company’s Board of Directors, acquired 355,461 ordinary shares in the Company (in aggregate) for total consideration of approximately $1,018,450.

Executive leadership appointments
Iris Energy is pleased to advise the following executive leadership appointments effective immediately.

• Kent Draper – Chief Commercial Officer. Kent has been with Iris Energy since 2020 and oversees commercial initiatives including project development, energy and hardware procurement, Government relations and JVs / M&A.
• Bom Shin – Head of Capital Markets. Bom has been with Iris Energy since 2019 and oversees capital markets initiatives including equity and debt financings, investor relations, marketing and public relations.

BC Hydro annual rate update
On March 21, 2023, as part of BC Hydro’s annual electricity rate review, the British Columbia Utilities Commission released an order approving, for the fiscal year commencing April 1, 2023: (i) an increase in the regulated rate by 0.97%; and (ii) setting of the Deferral Account Rate Rider (effectively a discount applicable to a user’s electricity costs) at 1.00% (vs. 2.00% for FY23).

The combined impact of the above order, all else being equal, is an expected increase in the Company’s all-in unit cost of electricity of ~2% (or an incremental increase of ~$0.001/kWh). This updated rate is fixed for the next 12 months, providing certainty across our BC projects.

Canal Flats update (0.8 EH/s, 30MW capacity) – BC, Canada
Canal Flats has been powered by 100% renewable energy since inception⁵.

The project achieved average monthly operating hashrate of 591 PH/s in March compared to 512 PH/s last month.

Mackenzie update (2.5 EH/s, 80MW capacity) – BC, Canada
Mackenzie has been powered by 100% renewable energy since inception⁵.

The project achieved average monthly operating hashrate of 862 PH/s in March compared to 798 PH/s last month.

Prince George update (1.6 EH/s, 50MW capacity) – BC, Canada
Prince George has been powered by 100% renewable energy since inception⁵.

The project achieved average monthly operating hashrate of 458 PH/s in March compared to 420 PH/s last month.

Childress update (0.6 EH/s, 20MW capacity) – Texas, USA
The 600MW bulk power substation is nearing energization, which will complete the connection of the site to the ERCOT grid. Commissioning of the first 20MW data center (supporting ~0.6 EH/s) is expected to commence in the coming weeks.

Structural and mechanical installation for the first 20MW data center building is complete and electrical fit out of the first three (of a total of eight) sections was completed during the month (with the remaining sections underway).

The Company’s significant upfront investment in key infrastructure at Childress (such as the 600MW bulk power substation and first 100MW primary substation) provides the ability to rapidly and efficiently expand beyond the Company’s first 20MW (580MW of potential expansion capacity). Planning is underway to utilize additional power on site.         

Community engagement

Texas, USA

• 4-H, one of the Company’s Community Grant recipients in Childress, recently launched a student’s robotics club. A member of the Iris Energy team stopped by during their last meeting and the children were able to show off their robotics-building and coding skills
• Iris Energy sponsored the Childress High School basketball team to attend a Spurs game in San Antonio to congratulate them on making the state championships
• David Shaw, COO of Iris Energy, spoke with the local Childress Rotary Club about the future of the Company in Childress, with local business representatives given the opportunity to ask questions about the project and its expected impact on the community

BC, Canada

• Iris Energy sponsored the BC Provincial Hockey Championship (Tier 4, Under 13) held in Invermere, British Columbia, near our site in Canal Flats. The community hosted teams from across the province to face off as part of this memorable experience
• The Mackenzie team hosted a booth at the McLeod Lake Indian Band Career Fair to actively engage with potential local candidates about career opportunities with Iris Energy, as active recruitment is underway

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 760MW of announced power capacity.

Technical commentary
The Company’s average operating hashrate was 1,912 PH/s in March (compared to 1,730 PH/s in February), with the increase primarily attributable to the installation of additional miners across the BC sites. The increase in Bitcoin mined (173 vs. 156 in February) and electricity costs ($2.2 million vs. $1.9 million in February) were primarily attributable to the installation of the additional miners as well as three additional days in the month (with Bitcoin mined partially impacted by an increase in the difficulty-implied global hashrate during the period). Adjusted electricity costs per Bitcoin was $11.5k in March (compared to $10.6k in February), with the increase primarily attributable to an increase in the difficulty-implied global hashrate during the period.

* Total miners comprise 5.6 EH/s of S19j Pro miners plus an additional ~0.1 EH/s of lower efficiency miners. As noted in the table below, the Company’s existing data center capacity is estimated to support ~5.5 EH/s of Bitmain S19j Pro miners.

¹ All timing references in this investor update are to calendar quarters and calendar years, 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 The Company’s unadjusted electricity costs per Bitcoin mined are currently elevated primarily due to excess demand charges attributable to average unutilized power capacity (due to termination of hosting arrangements in connection with certain of the Group’s limited recourse equipment financing facilities). The adjusted electricity costs per Bitcoin mined excludes such excess demand charges (i.e., assumes unit electricity costs of ~$0.045/kWh). As our operating capacity ramps up and demand charges are amortized over a greater energy consumption, all else being equal, we currently expect our electricity costs per Bitcoin mined to normalize at approximately 90MW of energy usage.
⁴ As at February 28, 2023.
⁵ Currently approximately 97% directly from renewable energy sources; approximately 3% from purchase of RECs.
⁶ Comprises actual power usage for Canal Flats, Mackenzie and Prince George.
⁷ Includes mix of lower efficiency hardware, which is estimated to represent less than 2% of the operating 3.1 EH/s.
⁸ Includes mix of lower efficiency hardware, which is estimated to represent less than 5% of non-operating miners in transit and/or pending deployment.
⁹ Reflects estimated hashrate capacity by site assuming full utilization of available data center capacity with Bitmain S19j Pro miners.
¹⁰ Decisions around how much, and when, data center capacity above an initial 20MW will be built at Childress are being assessed.
