SYDNEY, AUSTRALIA, September 13, 2022 (GLOBE NEWSWIRE) --
Iris Energy Limited (NASDAQ: IREN)
(“Iris Energy” or “the Company”), a leading owner and operator of institutional-grade, highly efficient Bitcoin mining data centers powered by 100% renewable energy, today reported its financial results for the full year ended June 30, 2022. All
$ amounts are in United States Dollars (“USD”) unless otherwise stated.
“We are pleased to report record financial and operating results as part
of our inaugural full year report as a listed company,” said Daniel Roberts, Co-Founder and Co-Chief Executive Officer of Iris Energy.
“FY22 was a transformational year for Iris Energy where we continued to
deliver on our plan to significantly expand our operations beyond our first site in Canal Flats (BC, Canada) that has been operating since 2019. Our average operating hashrate increased by 611% during the period (from 0.1 EH/s to 0.7 EH/s), and our
operating capacity is expected to be 3.7 EH/s by the end of September 2022 across three operating sites in BC, Canada.”
“Our proprietary data centers continue to lead the market in terms of
efficiency, with Iris Energy mining 16% more Bitcoin per EH/s compared to the peer average5. Further, our strategy of selling our mined Bitcoin daily has allowed us to achieve a 75% higher average realized price per Bitcoin for fiscal
year 2022 compared to the average Bitcoin price in June 20226. These factors helped grow our revenue by 647% to $59.0 million and operating cash flows by 1,124% to $21.6 million.”
Daniel Roberts concluded, “Looking forward, the recent volatility in the
Bitcoin price and related industry challenges reaffirms our confidence in our long-term, vertically integrated strategy. We remain focused on building a multi-decade, institutional grade, infrastructure platform while maintaining balance sheet
discipline.”
1 Adjusted EBITDA is a non-IFRS measure. See page 6 for
reconciliation to net profit/(loss) after income tax expense, the nearest IFRS measure.
2 Adjusted EBITDA Margin is a non-IFRS measure. See page 6 for
reconciliation to net profit/(loss) after income tax expense, the nearest IFRS measure.
3 Currently approximately 97% directly from renewable energy
sources; approximately 3% from purchase of RECs.
4 Existing equipment financing is limited recourse financing
within wholly owned subsidiaries of the Company.
5 Calculated as the average of monthly Bitcoin mined per EH/s
between January 1, 2022 and August 31, 2022 with reference to peer public disclosures. Peer group comprises Bitfarms, Core Scientific, Hut 8, Riot Blockchain, Argo Blockchain, Marathon Digital, Hive Blockchain, Cleanspark and Greenidge.
6 Iris Energy FY22 (July 1, 2021 – June 30, 2022) average realized
Bitcoin price of $42,216 compared to average June 2022 Bitcoin price of $24,182 (calculated using Nasdaq data feed).

“I am proud of what Iris Energy has accomplished over the last 12
months,” said Lindsay Ward, Iris Energy’s President. “Our team’s extensive in-house construction management and operational expertise has allowed us to efficiently and rapidly expand our operating footprint across North America ahead of schedule.
By calendar year end, we anticipate having 4.7 EH/s of our 6.0 EH/s of operating capacity energized.”
Full Year FY22 Results
Iris Energy generated record revenue during the period ($59.0 million
vs. $7.9 million in the prior period), attributable to the increase in the Company’s average operating hashrate and a higher average realized price per Bitcoin (despite an increase in the global hashrate).
Notwithstanding an increase in electricity and other site costs during
the period ($15.6 million vs. $2.9 million in the prior period), as well as an increase in the global hashrate and lower transaction fees, the Company’s average electricity costs per Bitcoin mined reduced ($7,850 vs. $9,888 in the prior year),
primarily as a result of materially improved power efficiency of our mining fleet (driven by ongoing installation of new generation miners).
Other corporate expenses, excluding foreign exchange gains and losses,
one-off expenses, depreciation and amortization and shared-based compensation expense, increased during the period ($17.2 million vs. $3.7 million in the prior period), primarily attributable to higher headcount to support our data center build out
and commencement of operations across North America, as well as related insurance costs.
The Company generated record Adjusted EBITDA1 ($26.2 million
vs. $1.4 million in the prior period) and Adjusted EBITDA Margin2 (44% vs. 18% in the prior period) during the period, demonstrating the attractive operating leverage within the business (i.e. higher average revenue and lower average
electricity costs per Bitcoin mined as compared to the prior period, partially offset by higher corporate costs).
Cash flow from operations was $21.6 million for the period (vs. $1.8
million in the prior period), primarily attributable to the increase in the Company’s average operating hashrate and a higher average realized price per Bitcoin (despite an increase in the global hashrate).
Net Loss After Tax for the period was $419.8 million for the period (vs.
Net Loss After Tax of $60.4 million in the prior period), primarily attributable to a one-off non-cash mark-to-market of convertible instruments converted into equity at IPO ($418.7 million impact during the period).
Cash and cash equivalents as of June 30, 2022 was $110.0 million, with
no corporate debt held by the Company on its balance sheet7.

8 Utilization of the remaining $83.3 million of payments in
respect of additional contracted miners above 6.0 EH/s continue to be subject to ongoing discussions with Bitmain. The Company has not made all recent scheduled payments under the separate $400 million hardware purchase contract and does not
currently expect to make upcoming scheduled payments in respect of future deliveries. The timing and volume of any additional future deliveries under that contract (including utilization of the remaining $83.3 million of payments) is subject to
ongoing discussions with Bitmain. The Company can make no assurances as to the outcome of these discussions, including the impact on timing of any future deliveries or payments made under that contract.
9 Operating capacity with respect to the final 30MW phase of
Mackenzie is expected to increase from 0.6 EH/s to 1.0 EH/s to support 0.4 EH/s of the recently announced 1.7 EH/s of additional Bitmain S19j Pro miners.

projections, objectives, performance or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking.
These forward-looking statements are based on management’s current expectations

hardware purchase contracts with Bitmain on a timely basis could result in liquidated damages, claims for specific performance or other claims against Iris Energy, any of which could result in a loss of all or a portion of any prepayments or
deposits made under the relevant contract or other liabilities in respect of the relevant contract, and could also result in Iris Energy not receiving certain discounts under the relevant contract or receiving the relevant hardware at all, any of
which could adversely impact its business, operating expansion plans, financial condition, cash flows and results of operations; the terms of any additional financing, which could be less favorable or require Iris Energy to comply with more
onerous covenants or restrictions, any of which could restrict its business operations and adversely impact its financial condition, cash flows and results of operations; competition; Bitcoin prices, which could adversely impact its financial
condition, cash flows and results of operations, as well as its ability to raise additional financing; risks related to health pandemics including those of COVID-19; changes in regulation of digital assets; and other important factors discussed

Non-IFRS Financial Measures
This release includes non-IFRS financial measures, including Adjusted
EBITDA and Adjusted EBITDA Margin. We provide Adjusted EBITDA and Adjusted EBITDA Margin in addition to, and not as a substitute for, measures of financial performance prepared in accordance with IFRS. There are a number of limitations related to
the use of Adjusted EBTIDA and Adjusted EBITDA Margin. For example, other companies, including companies in our industry, may calculate Adjusted EBITDA and Adjusted EBITDA Margin differently. The Company believes that these measures are important
and supplement discussions and analysis of its results of operations and enhances an understanding of its operating performance.
The Group uses EBITDA and Adjusted EBITDA as a metric that is useful for
assessing its operating performance before the impact of non-cash and other items.
EBITDA is net profit or (loss) from operations, as reported in profit
and loss, before finance income and expense, tax and depreciation and amortization.
Adjusted EBITDA is EBITDA adjusted for removing certain non-cash and
other items, including share- based payment expenses, foreign currency gains/(losses) and one-time transactions. See below for a reconciliation to net profit/(loss) after income tax expense, the nearest applicable IFRS measure, for the periods
presented.

subsidiaries of the Company. Net assets = $570m total assets less $108m total borrowings as of June 30, 2022. Indicative estimated net cash spend to fund miners and infrastructure required to reach 6.0 EH/s of operating capacity (as of
June 30, 2022). Net cash spend comprises expected remaining capex net of anticipated sales tax and connection deposit refunds. Please see the Coinwarz Bitcoin Mining Calculator (https://www.coinwarz.com/mining/bitcoin/calculator). Inputs
for 6.0 EH/s: 6,000 PH/s (hashrate), 190MW (power consumption) and $0.048/kWh (electricity costs) – prefilled link here. Note electricity cost assumption is based on existing BC operations; as Texas is a deregulated power market, future
electricity costs for Texas are currently unknown, and are expected to be to influenced by, amongst other things, prevailing market prices around the time of commissioning. Illustrative net revenue = Illustrative gross revenue less assumed
mining pool fees. Illustrative mining profit = Illustrative net revenue less assumed electricity costs. The illustrative outputs assume nameplate hashrate is fully installed and operating today using the above assumptions. These assumptions
are likely to be different in the future and users should input their own assumptions. Mining profitability potential Assuming 6.0 EH/s of hardware is fully operational today6 (annualized) Bitcoin Price Net Revenue5 Mining

and uncertainties surrounding deployment could delay or prevent Iris Energy from achieving the anticipated hashrate capacity. Operating capacity with respect to the final 30MW phase at Mackenzie is expected to increase from 0.6 EH/s to 1.0
EH/s to support 0.4 EH/s of the recently announced 1.7 EH/s of additional Bitmain S19j Pro miners. The average variable cost of electricity for our current operations is approximately C$0.05096/kWh. In addition, we pay a standing monthly
demand charge of approximately C$8.6960/kVA (assuming full load uptime). Average “all-in” power price assumes CADUSD exchange rate of 0.78 as well as application of a 2% Deferral Account Rate Rider (discount) applicable until April 1, 2023.

Financial Summary

FY22 results – strong revenue and earnings growth YoY +611% +422% +647% +1,791% Adjusted EBITDA is
a non-IFRS measure. Please refer to page 23 for reconciliation to the comparable IFRS measure. 22

FY22 results – Adjusted EBITDA 23 Non-cash. Founders primarily relate to $75 strike options ($370 -
$1,850 initial share price vesting) Non-cash mark-to-market of convertible notes converted into equity at IPO Electricity and other site costs includes electricity charges, site employee benefits, repairs and maintenance and site utilities.
Share-based payments expense includes expenses recorded on Founder options, including (1) Founder price target options (Executive Director Liquidity and Price Target Options) that vested on IPO during the quarter ended December 31, 2021. No
further expense will be recorded in relation to these price target options. (2) Founder long-term options (Executive Director Long-term Target Options) which were granted in September 2021 in connection with the IPO. These long-term options
are currently "out of the money" with an exercise price of $75 and initial share price vesting conditions of $370, $650, $925 and $1,850 for each tranche granted. See note 31 of the consolidated financial statements for further information.
Share-based payments expense includes expense recorded in relation to incentives issued under the Employee Share Plans, Employee Option Plan and Non-Executive Director Option Plan. Other expense items includes expenses incurred relating
to the IPO and the exploration of multiple financing options that did not proceed due to current market conditions and available financing terms. Includes fair value losses recorded on SAFE, convertible notes and associated embedded
derivatives that were converted into ordinary shares upon the Group’s listing on the Nasdaq. The net fair value losses recorded on these instruments represents the movement in the share price from date of issuance of these instruments to the
IPO listing price of $28. All of these instruments converted to ordinary shares on November 16, 2021, the associated fair value gains/(losses) are non-cash movements and do not impact the cash position of the Group. See note 8 of the
consolidated financial statements for further information. The Group uses EBITDA and Adjusted EBITDA as a metric that is useful for assessing its operating performance before the impact of non-cash and other items. EBITDA is net profit or
(loss) from operations, as reported in profit and loss, before finance income and expense, tax and depreciation and amortization. Adjusted EBITDA is EBITDA adjusted for removing certain non-cash and other items, including share-based payment
expenses, foreign currency gains/(losses) and one-time transactions. US$’000 Year ended June 30, 2022 Year ended June 30, 2021 Bitcoin mining revenue 59,037 7,898 Electricity and other site costs 1 (15,583) (2,855) Other
