Corporate, financial and operational updates

On November 21, the Company provided a corporate update and announced certain preliminary financial information and operational updates for the three months ended September 30, 2022, as well as certain additional preliminary financial information with respect to the month of October 2022.

The update can be accessed via the following link: https://investors.irisenergy.co/node/7706/html

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

Canal Flats has been powered by 100% renewable energy since inception¹⁰.

The project achieved average monthly operating hashrate of 570 PH/s in November (0.8 EH/s of capacity)¹¹.

Mackenzie update (2.5 EH/s, 80MW) – BC, Canada

Mackenzie has been powered by 100% renewable energy since inception¹⁰.

The project achieved average monthly operating hashrate of 268 PH/s in November (2.5 EH/s of capacity)¹¹.

Expansion from 50MW to 80MW was energized on December 6, 2022, three weeks ahead of schedule, and will utilize the remaining 10MW of the third data center building (20MW) and a fourth data center building (20MW) with both internal fit-outs complete.

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

Prince George has been powered by 100% renewable energy since inception¹⁰.

The project achieved average monthly operating hashrate of 607 PH/s in November (1.4 EH/s of capacity)¹¹.

Childress update (0.7 EH/s, 20MW) – Texas, USA

Foundations and earthworks for the substation were completed during the month. Structural steel for the first data center building (20MW) was erected as earthworks, and the substation area is prepared for the upcoming delivery and installation of the 600MW transformer and main power transformers.

Key civil, data center building, substation, and electrical contractors continue to progress construction activities and are being managed by a core group of Iris Energy employees based in Childress.

Approximately $18 million in previous deposits with AEP Texas are expected to be refunded following energization at Childress.

Community engagement

In November 2022, Iris Energy sponsored the Windermere Valley Saddle Club, a non-profit horse club that aims to encourage and educate the youth of the Canal Flats Valley about horsemanship. In Mackenzie, Iris Energy team members honoured those who have served by laying a wreath in the Remembrance Day ceremony.

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 1,445 PH/s in November 2022 (compared to 3,899 PH/s in October⁸), with the decrease primarily attributable to the termination of hosting arrangements during the month in connection with certain of the Company’s limited recourse equipment financing facilities as described above⁹. The corresponding decrease in Bitcoin mined (151 vs. 448 in October) and electricity costs ($1.9 million vs. $4.2 million in October⁸) were also primarily attributable to the termination of these hosting arrangements.

The energization of the 30MW expansion at Mackenzie ahead of schedule, increases the Company’s total available data center capacity to 160MW, capable of powering approximately 4.7 EH/s of miners (via self-mining and/or hosting).

The increase in the Company’s unadjusted electricity costs per Bitcoin mined ($12.6k vs. $10.2k adj vs. $9.3k in October⁸) was primarily driven by excess demand charges attributable to average unutilized power capacity (due to termination of relevant hosting arrangements as described above) as well as the increase in the average difficulty-implied global hashrate during the period.

Restatement of prior period metrics

The Company has refined its methodology for calculating electricity costs and monthly average operating hashrate to align with the respective reported Bitcoin mined each month by one day as a result of time zones and mining pool payout timing.

Please see below for the restated average operating hashrate.

2022	Jan	Feb	Mar	Apr	May	Jun	Jul	Aug	Sep	Oct	Nov
Avg operating hashrate (PH/s) – restated	802	844	849	1,028	1,165	1,164	1,120	2,162	2,679	3,899	1,445
BTC mined – unchanged	126	110	121	137	151	148	154	301	325	448	151*

* Under the previous methodology, Bitcoin mined divided by average operating hashrate (1.347 EH/s) would have been ~112 for November (vs. ~105 under the restated methodology).

Miner Shipping Schedule*	Hardware	Units	EH/s (incremental)	EH/s (cumulative)
Operating (as of December 12)**	S19j Pro¹³	12,042	1.1	1.1

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 increase in the Company’s unadjusted electricity costs per Bitcoin mined ($12.6k vs. $10.2k adj vs. $9.3k in October) was primarily driven by 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) as well as the increase in the average difficulty-implied global hashrate during the period. The adjusted electricity costs per Bitcoin mined ($10.2k) excludes such excess demand charges (i.e. assumes unit electricity costs of ~$0.046/kWh).
⁴ Reflects USD equivalent, unaudited preliminary cash balance as of November 30, 2022 (excluding cash held by the two relevant SPV borrowers). Reflects acceleration of outstanding loans under two of the Group's three outstanding limited recourse equipment financing facilities and assumes foreclosure by the lender thereunder against the collateral securing such facilities held by the applicable non-recourse SPV borrowers, and also assumes repayment by the Group on behalf of the applicable SPV borrower of $1m of outstanding loans under the Group's third limited recourse equipment financing facility. See the Company's Report on Form 6-K filed on November 21, 2022 for further information. Following such acceleration and foreclosure, and such repayment, as applicable, the Group would not have any indebtedness for borrowed money outstanding.
⁵ Indicative estimated remaining net capital expenditure to build out 180MW of infrastructure and repay $1m of outstanding loans under the Group’s third limited recourse equipment financing facility (net of anticipated proceeds from hardware sales and anticipated tax and deposit refunds). Excludes impact of all other potential future cash movements (e.g. operating cashflows and financing cashflows).
⁶ Subject to market conditions and regulatory approvals.
⁷ Comprises ~1.1 EH/s of miners in operation as of December 12 (including ~0.2 EH/s of miners securing the facility with the Company’s third limited recourse equipment financing facility in respect of which the Company has received a notice of acceleration as described in the Company's Report on Form 6-K filed on November 21, 2022) and ~0.9 EH/s of miners in transit and/or pending deployment. The Company is currently finalizing monetization transactions with respect to ~0.4 EH/s of miners which are in transit and/or pending deployment. There can be no assurance as to the timing or terms of any such transaction, or whether any such transaction will be consummated at all.
⁸ Certain metrics reported for prior periods have been restated in this investor update to reflect refined methodology. See section ‘Restatement of prior period metrics’ for further details.
⁹ Refer to the Company’s announcements on November 7, 2022 and November 21, 2022.
¹⁰ Currently approximately 97% directly from renewable energy sources; approximately 3% from purchase of RECs.
¹¹ However figures are post impact of termination of hosting arrangements associated with certain of the Company’s limited recourse equipment financing facilities as described above.
¹² Comprises actual power usage for Canal Flats, Mackenzie and Prince George.
¹³ Includes mix of lower efficiency hardware, which is estimated to represent less than 10% of the operating 1.1 EH/s.
¹⁴ Includes mix of lower efficiency hardware, which is estimated to represent less than 4% of miners in transit and/or pending deployment.
¹⁵ Reflects estimated hashrate capacity by site assuming full utilization of available data center capacity with additional Bitmain S19j Pro miners.
¹⁶ Decisions around how much, and when, data center capacity above an initial 20MW will be built at Childress are being assessed.
