Operating guidance increased from 3.7 EH/s to 4.3 EH/s in 2022

Mackenzie development activities progressing ahead of schedule

SYDNEY, Australia, July 07, 2022 (GLOBE NEWSWIRE) — Iris Energy Limited (NASDAQ: IREN) (“Iris Energy” or “the Company”), a leading sustainable Bitcoin miner which is building an institutional-grade infrastructure platform (4.3 EH/s expected to be operational by the end of Q4 2022), today published a monthly investor update for June 2022, containing its results from operations as well as construction and development updates.

Corporate update

On June 21, 2022, the Company announced that, given current market conditions, it intends to defer additional major capital expenditure for work beyond the initial 4.3 EH/s of operating capacity to preserve balance sheet flexibility.

The Company has explored multiple financing options presented to it in recent months, and has determined that maintaining balance sheet flexibility is prudent having regard to market conditions and available financing terms.

As market conditions have deteriorated, the Company continues to believe this is the prudent approach. As a result, the Company expects to defer major additional capital expenditure until the current market uncertainty subsides and financing terms improve. The Company will continue to monitor funding markets closely, and if conditions become favorable, the Company expects to explore raising additional capital.

The Company has made $130m of payments in respect of contracted miners above the initial 4.3 EH/s, which are subject to ongoing discussions.⁵ The Company’s planning and contractual arrangements have also mitigated material financial commitments to the broader buildout of Childress infrastructure beyond ongoing preparatory construction activities.

While the Company continues to target expansion of total operating capacity above 4.3 EH/s, such plans are expected to be delayed and the Company will continue to review such plans in light of evolving market conditions.

The Company expects to continue liquidating Bitcoin mining rewards on a daily basis, as has been the case since Iris Energy started mining Bitcoin in 2019, including when Bitcoin hit an all-time high of approximately $68,000 in November 2021.

As of May 31, 2022, the Company had approximately (preliminary unaudited)⁶:

• $454m of total equity
• Nil corporate-level debt⁷
• $93m of cash (after expected remaining capital expenditure to achieve the initial 4.3 EH/s)⁸
• $317m investment in miners and infrastructure expected in order to achieve the initial 4.3 EH/s⁹
• $130m of payments in respect of contracted miners above the initial 4.3 EH/s
• $19m of deposits and prepayments¹⁰ with AEP for the 600MW high-voltage electrical connection at Childress

4.3 EH/s of operating capacity would represent illustrative annualized mining profit of $67m (based on a $20k Bitcoin price¹¹) if installed and operating today.

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

Canal Flats has been powered by 100% renewable energy since inception.¹²

Canal Flats achieved average monthly operating hashrate in June of 872 PH/s, in line with May (873 PH/s). The project continues to exceed previously announced site capacity of 0.7 EH/s.

Mackenzie update (2.1 EH/s, 50MW initial / 80MW total) – BC, Canada

Mackenzie has been powered by 100% renewable energy since inception.¹²

The initial 9MW at Mackenzie achieved average monthly operating hashrate in June of 292 PH/s, in line with May (292 PH/s).

Construction of the remainder of the first 1.5 EH/s (50MW) remains on track for Q3 2022. The internal fit out of the data center buildings is complete and commissioning activities are underway.

All major electrical equipment has been installed in the substation and testing and commissioning activities are ongoing. Construction of the high voltage connection to the BC Hydro transmission network has commenced.

Upon completion, 80MW of proprietary data centers are expected to power an additional ~22,000 Bitmain S19j Pro and S19j miners (already under contract), generating 2.1 EH/s of incremental hashrate.

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

Foundations and structural steel for the three data center buildings (2 x 20MW, 1 x 10MW) is complete.

Remaining building construction is advanced on the first and second data center building (20MW and 10MW) and is underway for the third data center building (20MW). Internal fit out of the first data center building (20MW) and second data center building (10MW) is also progressing.

Prince George remains on track to be energized by the end of Q3 2022 and upon completion, 50MW of proprietary data centers are expected to power an additional ~15,000 Bitmain S19j Pro and S19j miners (already under contract), generating 1.4 EH/s of incremental hashrate.

Childress update – Texas, USA

As previously announced, the Company intends to defer additional major capital expenditure related to the broader buildout of Childress infrastructure. Preparatory construction activities are intended to continue at Childress in order to preserve the opportunity to scale once market conditions improve.

Procurement and early construction activities continued to progress (all required construction permits are in place). Construction of the access road to the main development area and site civil works are ongoing. Purchase orders have been placed on key long-lead items, including the 345kV step-down transformer, 138kV step-down transformer and associated circuit breakers.    

Community engagement

Iris Energy is proud to announce the Community Grants Program for Childress is open for applications. The program is a key component of our commitment to making a positive contribution to the local communities in which we operate. The program will provide funding for local initiatives that benefit the Childress community in the areas of community participation, sustainability, safety, diversity, technology and learning.

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 1,164 PH/s in June.

The decrease in electricity costs in June compared to May was primarily due to one less day in the month as well as foreign exchange impacts.

The comparatively higher electricity costs per Bitcoin mined across May and June (vs. April) are attributable to the Company paying a higher interim unit cost of power at Mackenzie via the 9MW temporary 25kV distribution feed. Rates at Mackenzie are expected to revert to the same lower transmission rate as Canal Flats upon commissioning of the remainder of the first 50MW in Q3 2022.

* 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).

* Reflects Bitcoin mined post deduction of mining pool fees (currently 0.5% x total Bitcoin mined).
** The decrease in electricity costs (vs. May) was primarily due to one less day in the month and foreign exchange impacts.
