Corporate update

Increasing self-mining capacity from 2.0 EH/s to 5.5 EH/s

On February 13, Iris Energy announced it is increasing its self-mining capacity from 2.0 EH/s to 5.5 EH/s.

The Company successfully utilized remaining prepayments of US$67 million under its 10 EH/s contract with Bitmain, including a concurrent sale of 2.3 EH/s of the remaining 6.7 EH/s contracted miners to a third party, to acquire 4.4 EH/s of new S19j Pro miners without any additional cash outlay.

Following the transaction, the Group’s obligations under its existing 10 EH/s contract with Bitmain have been fully resolved, with no remaining commitments. The Group remains debt free⁴.

The Company subsequently completed the sale of certain surplus miners, above 5.5 EH/s of self-mining capacity, resulting in net cash proceeds of approximately $8 million.

Second quarter FY23 financial results

On February 15, Iris Energy reported financial results for the three and six-months ended December 31, 2022 and provided a general business update. 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 capacity) – BC, Canada

Canal Flats has been powered by 100% renewable energy since inception⁵.

The project achieved average monthly operating hashrate of 512 PH/s in February compared to 509 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 798 PH/s in February compared to 654 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 420 PH/s in February compared to 411 PH/s last month.

Childress update (0.6 EH/s, 20MW capacity) – Texas, USA

The first data center building (20MW) structure is complete, and installation of mechanical equipment including exhaust and recirculation fans has commenced. Internal data center electrical fit out continued during the month, while energization of the 600MW bulk substation (345kV) and commissioning of the 100MW primary substation (138kV) is expected in the coming months.

The initial 20MW data center is nearing completion in the coming months, with orders already placed for the next 20MW of low voltage building transformers.

Community engagement

Employees from our Mackenzie site volunteered during the Mackenzie ‘Strong Thank You to Front Line Workers’ event as well as providing a donation of C$5,000. This local community event, sponsored by the Mackenzie Chamber of Commerce, was a special occasion to honor and thank all the health care workers, emergency responders, and essential workers in Mackenzie who have been working hard during and following the pandemic.

In Childress, the High School chemistry department was one of our Community Grant recipients last year and purchased science experiment supplies which are now being used by the students this spring semester.

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 1,730 PH/s in February (compared to 1,575 PH/s in January), with the increase primarily attributable to the installation of additional miners at Mackenzie. Despite the increase in average operating hashrate, the number of Bitcoin mined decreased during the period (156 vs. 172 in January) due to an increase in the difficulty-implied global hashrate and three fewer days in the month of February. Adjusted electricity costs per Bitcoin was $10.6k in February (compared to $9.8k in January), with the increase also driven by the increase in the difficulty-implied global hashrate.

* Excludes ~3.6 EH/s of miners securing equipment financing facilities with the Company’s two remaining SPV borrowers in respect of which a receiver has been appointed.
** 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 ~$0.046/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 cost per Bitcoin to normalize at approximately 90MW of energy usage.
⁴ Reflects acceleration of outstanding loans under the Group's two outstanding limited recourse equipment financing facilities, in respect of which the relevant lender is pursuing enforcement proceedings, and assumes foreclosure by the lender thereunder against the collateral securing such facilities held by the relevant SPV borrowers. See the Company's Reports on Form 6-K filed on November 21, 2022 and February 15, 2023, and Registration Statement on Form F-1, as amended, initially filed on September 23, 2022, for further information. Following such acceleration and foreclosure, the Group would not have any indebtedness for borrowed money outstanding.
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 6% of the operating 1.7 EH/s.
⁸ Includes mix of lower efficiency hardware, which is estimated to represent less than 3% 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.
