•

Successfully completed $232 million IPO and listing on Nasdaq led by J.P. Morgan, Canaccord Genuity and Citigroup

•

Construction ahead of schedule at Mackenzie (BC, Canada) with commissioning of the first 0.3 EH/s (9MW) now expected in early Q2 2022 followed by full ramp up to 1.5 EH/s (50MW) expected during Q3 2022

•

Prince George (BC, Canada) on track to deliver 1.4 EH/s (50MW) in Q3 2022 and expansion to 2.4 EH/s (85MW) anticipated in 2023

•

Post quarter end, a transformational 600MW connection agreement was executed with AEP Texas, increasing power capacity to 765MW (~22 EH/s²)

SYDNEY, AUSTRALIA (February 9, 2022) – Iris Energy Limited (NASDAQ: IREN) (“Iris Energy” or “the Company”), a leading sustainable Bitcoin miner with 15 EH/s of secured miners, today reported its financial results for the quarter and half-year ended December 31, 2021. All $ amounts are in United States Dollars (“USD”) and all A$ amounts are in Australian Dollars (“AUD“), unless otherwise stated.

“We are pleased to report record financial and operating results as part of our inaugural quarterly and half-yearly report as a listed company,” stated Daniel Roberts, Co-Chief Executive Officer and Founder of Iris Energy. “Iris Energy is on track to be one of the largest listed Bitcoin miners with 15 EH/s³ of hardware secured (~10 EH/s expected to be operational by early 2023) and 765MW of grid-connected power operating or under construction. Led by a seasoned management team, we are building a global energy and specialized data center infrastructure platform targeting markets with excess and under-utilized renewables where we can solve a problem. We are looking forward to the upcoming 12 to 18 months, which we expect will be transformational for the Company.”

¹ Currently 98% directly from renewable energy sources; 2% from purchase of RECs.

² Equivalent hashrate potential for the power capacity assuming installation of Bitmain S19j Pro miners.

³ In addition to 0.8 EH/s currently operating, 14.4 EH/s of aggregate nameplate hashrate capacity has been secured through binding contracts for future delivery of miners.

Iris Energy’s President, Lindsay Ward, commented, “Construction at Mackenzie and Prince George, our two near-term expansion sites in British Columbia, continues to progress and remains on track to deliver material additional hashrate over the coming quarters. In addition, development works continue across our secured sites in Canada, the USA and Asia-Pacific, which are expected to support >1GW of additional aggregate power capacity capable of powering growth well beyond the Company’s 15 EH/s³ of secured miners (~530MW).”

Second Quarter FY2022 Results

Iris Energy generated record quarterly revenue ($20.0 million vs. $10.4 million during the previous quarter), Adjusted EBITDA ($14.3 million vs. $5.6 million during the previous quarter) and Adjusted EBITDA Margin (72% vs. 54% during the previous quarter). The increase in revenue, Adjusted EBITDA and Adjusted EBITDA Margin were attributable to a higher average Bitcoin price during the period as well as an increase in the Company’s average operating hashrate.

Net Profit After Tax for the quarter was $71.7 million (A$98.8 million), compared to a Net Loss After Tax of $418.9 million (A$580.0 million) during the previous quarter, which is primarily attributable to a one-off non-cash mark-to-market of convertible notes converted into equity at IPO.

Iris Energy continued to generate positive cash flow from operations during the quarter, demonstrating the attractive cash profitability of the Company’s business model and supporting reinvestment into mining hardware and infrastructure, and its total assets increased to $495.2 million (A$682.1 million) as of December 31, 2021.

Operating and Financial Overview

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. The below table reconciles (Adjusted) EBITDA to Net profit/(loss) after tax.

HODL considerations 16 Non-HODL HODL Rationale Immediate ownership of Bitcoin todayPotential to borrow against BitcoinInvestors not required to self-custodyLess complexity for management teams (trading Bitcoin vs. building infrastructure)‘Locking up’ Bitcoin circulating supply Considerations In down markets, double hit to profit and balance sheetRisk of liquidation / margin calls associated with Bitcoin price volatility. e.g. may require sale of Bitcoin and/or equity at unattractive levelsReliance on capital markets to continue funding capex and opexTrust in large corporates and third parties to custody Bitcoin Rationale Self-funding for rapid growth of computing powerReturn on investment today is extremely attractive (>100% cash yields1)Reinvest Bitcoin today to generate more Bitcoin tomorrow: 1 Bitcoin held on balance sheet; or10 x S19j Pro1 (1,000 TH/s) = 1 Bitcoin every ~7 months1 Future optionality to HODL greater amount of Bitcoin, continue reinvesting or distributions (investors could then self-custody)Less dilutive than raising equity to finance capex and opex Considerations Optics of no Bitcoin on balance sheet (some investors with higher time preferences may prefer to see Bitcoin today)Generating greater exposure to Bitcoin via expansionLower risk of margin calls on Bitcoin leverage Today’s strategy is to reinvest Bitcoin to fund rapid expansion to 15 EH/s, building one of the largest listed Bitcoin miners 1.

Morgan, Cannaccord Genuity and Citigroup and raised total gross proceeds of US dollar (‘US$’) 231.5 million. The Group is a Bitcoin mining company that builds, owns and operates data center and electrical infrastructure powered by abundant and/or under-utilized renewable energy.

The unaudited interim consolidated financial statements were authorized for issue, in accordance with a resolution of Directors, on 10 February 2022. The Directors have the power to amend and reissue the unaudited interim consolidated financial statements.

Note 2. Significant accounting policies

These unaudited interim consolidated financial statements for the periods ended 31 December 2021 have been prepared in accordance with IAS 34 Interim Financial Reporting, and should be read in conjunction with the Group’s last annual consolidated financial statements as at and for the year ended 30 June 2021 (‘last annual financial statements’). They do not include all of the information required for a complete set of financial statements prepared in accordance with International Financial Reporting Standards (‘IFRS’). However, selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in the Group’s financial position and performance since the last annual financial statements for the year ended 30 June 2021.

The principal accounting policies adopted are consistent with those of the previous financial year and corresponding interim reporting period, except for the policies stated below.

Reverse share split

On November 4, 2021, the Company effected a 1-for-5 reverse share split of its ordinary shares. Unless otherwise indicated, the per ordinary share information has been retroactively adjusted to reflect the 1-for-5 reverse share split.

Note 2. Significant accounting policies (continued)

New or amended Accounting Standards and Interpretations adopted

The Group has adopted all of the new or amended IFRS and Interpretations as issued by the International Accounting Standards Board (‘IASB’) that are mandatory for the current reporting period.

Any new or amended Accounting Standards or Interpretations that are not yet mandatory have not been early adopted. The Group believes that the impact of recently issued standards or amendments to existing standards that are not yet effective will not have a material impact on the Group’s unaudited interim consolidated financial statements.

Going concern

The Group has determined there is material uncertainty that may cast doubt on the Group’s ability to continue as a going concern but has concluded it is appropriate to prepare the consolidated interim financial statements on a going concern basis which contemplates continuity of normal business activities, the realization of assets and settlement of liabilities in the ordinary course of business and securing additional capital.

Since inception of the Company in November 2018, the Group has raised over A$670 million including the recent IPO which raised A$297.5 million, net of underwriting fees.

The ability of the Group to continue as a going concern depends upon the Group maintaining sustained positive free operating cash flows and securing additional capital to fund the contracted mining hardware purchases and infrastructure spend, as part of its growth plan. There are other risks and uncertainties affecting the Group’s operations including, but not limited to, the viability of the economics of Bitcoin mining and the ability to execute its business plan.

For the six months ended 31 December 2021, the Group generated positive operating cashflows of A$13 million (31 December 2020: A$0.1 million) and had net current assets of A$327.7 million (30 June 2021: net current liabilities of A$173.5 million) with net assets of $615.2 million (30 June 2021: net liabilities of A$65.9 million). For the six months ended 31 December 2021, the Group incurred a loss after tax of A$580 million (31 December 2020: A$2.2 million), this loss included a A$540.9 million fair value loss on hybrid instruments which converted to equity on 16 November 2021.

As further background, the Group’s miners are designed specifically to mine Bitcoin and its future success will depend in a large part upon the value of Bitcoin, and any sustained decline in its value could adversely affect the business and results of operations. Specifically, the revenues from Bitcoin mining operations are predominantly based upon two factors: (i) the number of Bitcoin rewards that are successfully mined and (ii) the value of Bitcoin. A significant decline in the market price of Bitcoin, an increase in the difficulty of Bitcoin mining, changes in the regulatory environment and/or adverse changes in other inherent risks would significantly negatively impact the Group’s operations. Due to the volatility of the Bitcoin price and the effects of possible changes in the other aforementioned factors, there can be no guarantee that future mining operations will be profitable.

The strategy to mitigate these risks and uncertainties is to execute a business plan aimed at continued operational efficiency, revenue growth, improving overall mining profit, managing operating and capital expenditure and working capital requirements, and securing additional financing, as needed. The Group is also in a position to wind down its operations (including not acquiring any additional mining hardware and/or incurring the associated infrastructure growth capital expenditure) in the event of unfavourable pricing in Bitcoin. The continuing viability of the Group and its ability to continue as a going concern and meet its debts and commitments as they fall due, are therefore dependent upon a number of factors which have been considered in preparing a cash flow forecast over the next 12 months to consider the going concern of the Group and the ability of the Group to achieve its growth plans. The key assumptions include:

●	the Bitcoin price remaining at a level higher than prior financial years and a lag in global hashrate, thereby contributing to sustained forecast positive free cash flow; and

●

the Group’s contracted mining hardware purchases and infrastructure spend will be funded by a combination of available cash (A$351.7 million as at 31 December 2021), operating cashflow and additional financing. Of the total contracted mining hardware purchases, US$326.7 million (A$450 million) is due to be paid before 31 December 2022, with a further US$172.4 million (A$237.5 million) due in 2023 giving a total contracted mining hardware purchases of US$449.1 million (A$687.5 million) (including estimated shipping and provincial sales tax) as at 31 December 2021.

Note 3. Operating segments

Identification of reportable operating segments

The Group operates primarily within one operating segment, being the operation of building and operating data center sites for the purpose of Bitcoin mining and reports to the Executive Leadership Team, which is made up of the Executive Directors and their Executive Officers (who are identified as the Chief Operating Decision Makers ‘CODM’) on the performance of the Group as a whole.

Unless stated otherwise, all amounts reported to the Board of Directors are determined in accordance with accounting policies that are consistent with those adopted in these unaudited interim consolidated financial statements. The information reported to the CODM is on a monthly basis.

The CODM 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. The accounting policies adopted for internal reporting to the CODM are consistent with those adopted in the financial statements.

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.

Note 15. Share-based payments

There Group has entered into a number of share-based compensation arrangements. Details of these arrangements, which are considered as options for accounting purposes, are described below:

Employee Share Plan

The Group’s Employee Share Plan is a loan-funded share scheme. These loan-funded shares generally vest subject to satisfying employment service periods (and in some cases, non-market-based performance milestones). The employment service periods are generally met in three equal tranches on the third, fourth and fifth anniversary of the grant date. Under this scheme, the Company issues a limited recourse loan (that has a maximum term of up to 9 years and 11 months) to employees for the sole purpose of acquiring shares in the Company. Upon disposal of any loan-funded shares by employees, the aggregate purchase price for the shares shall be applied by the Company to pay down the outstanding loan payable. The recourse on the loan is limited to the lower of the initial amount of the loan granted to the employee and the proceeds from the sale of the underlying shares. Employees are entitled to exercise the voting and dividend rights attached to the shares from the date of allocation. If the employee leaves the Company within the vesting period, the shares may be bought back by the Company at the original issue price and the loan is repaid. Loan-funded shares have been treated as options as required under IFRS 2 Share-based Payments. Vesting of instruments granted under the Employee Share Plan is dependent on specific service thresholds being met by the employee.

2021 Executive Director Liquidity and Price Target Options

On 20 January 2021, the Group’s board approved the grant of 1,000,000 options each to entities controlled by Daniel Roberts and William Roberts (each an Executive Director) to acquire ordinary shares at an exercise price of A$5.0005 with an expiration date of 20 December 2025. All ‘Executive Director Liquidity and Price Target Options’ vested on completion of the IPO on 17 November 2021 in accordance with the following vesting thresholds:

●	If the liquidity price or volume weighted average market price (‘VWAP’) of an ordinary share over any consecutive 20 trading day period is equal to or exceeds A$7.00: 300,000 options vest.

●	If the liquidity price or VWAP of an ordinary share over any consecutive 20 trading day period is equal to or exceeds A$9.00: 300,000 options vest.

●	If the liquidity price or VWAP of an ordinary share over any consecutive 20 trading day period is equal to or exceeds A$11.00: 400,000 options vest.

Notes to the unaudited interim consolidated financial statements
31 December 2021

Note 15. Share-based payments (continued)

The option holder is entitled to receive, in its capacity as a holder of the options, an income distribution per vested option equal to any dividend, distribution, capital return or buyback proceeds (collectively, ‘Distribution’) paid by the Company per ordinary share as if any vested options were exercised and ordinary shares issued to the option holder at the relevant time of such Distribution. The options are subject to customary adjustments to reflect any reorganization of the Company’s capital. As at 31 December 2021, none of the 2,000,000 outstanding vested ‘Executive Director Liquidity and Price Target Options’ have been exercised.

The Board approved an Employee Option Plan on 28 July 2021. The terms of the Employee Option Plan are substantially similar to the Employee Share Plan, with the main difference being that the incentives are issued in the form of options and loans are not provided to participants. If the employee leaves the Company within the vesting period of the options granted, the Board retains the absolute discretion to cancel any unvested options held by the employee. Vesting of options granted under the Employee Option Plan is dependent on specific service thresholds being met by the employee.

Non-Executive Director Option Plan

The Board approved a Non-Executive Director Option Plan (‘NED Option Plan’) on 28 July 2021. The terms of the NED Option Plan are substantially similar to the Employee Option Plan. Where an option holder ceases to be a Director of the Company within the vesting period of the options granted, the Board retains the absolute discretion to cancel any unvested options held by the option holder. Vesting of instruments granted under the NED Option Plan is dependent on specific service thresholds being met by the Non-Executive Director.

2021 Executive Director Long-term Target Options

On 18 August 2021, the Group’s shareholders approved the grant of 2,400,000 long-term options each to entities controlled by Daniel Roberts and William Roberts to acquire ordinary shares at an exercise price of US$75 per option (‘Long-term Target Options’). These options were granted on 14 September 2021, and have a contractual exercise period of 12 years.

The Long-term Target Options will vest in four tranches following listing of the Company, if the relevant ordinary share price is equal to or exceeds the corresponding vesting threshold and the relevant executive director has not voluntarily resigned as a director of the Company. The vesting thresholds are detailed below:

●	If the VWAP of an ordinary share over the immediately preceding 20 trading days is equal to or exceeds US$370: 600,000 Long-term Target Options will vest.

●	If the VWAP of an ordinary share over the immediately preceding 20 trading days is equal to or exceeds US$650: 600,000 Long-term Target Options will vest.

●	If the VWAP of an ordinary share over the immediately preceding 20 trading days is equal to or exceeds US$925: 600,000 Long-term Target Options will vest.

●	If the VWAP of an ordinary share over the immediately preceding 20 trading days is equal to or exceeds US$1,850: 600,000 Long-term Target Options will vest.

The VWAP vesting thresholds may also be triggered by a sale or takeover of the Company based upon the price per ordinary share received in such transaction.

The option holder is entitled to receive in its capacity as a holder of the options, a distribution paid by the Company per ordinary share as if the vested options were exercised and ordinary shares issued to the option holder at the relevant time of such distribution.

The options are subject to customary adjustments to reflect any reorganization of the Company’s capital, as well as adjustments to vesting thresholds including any future issuance of ordinary shares by the Company.

Valuation methodology

The fair value of instruments issued under the Employee Share Plan, Employee Option Plan and NED Option Plan have been measured using a Black-Scholes-Merton valuation model. The fair value of the Executive Director Liquidity and Price Target Options and 2021 Executive Director Long-term Target Options have been measured using a Monte-Carlo simulation. Service and non-market performance conditions attached to the arrangements were not taken into account when measuring fair value.

The following table list the inputs used in measuring the fair value of arrangements granted during the six months ended 31 December 2021:

Grant date	Dividend yield	Expected volatility	Risk free interest rate	Expected life (weighted average)	Grant date share price	Exercise Price	Fair value (weighted average)	Number of options granted

Significant Transactions with key management personnel

On or around 18 August 2021, the shareholders of the Company approved the issue of one B Class share each (for consideration of A$1.00 per B Class share) to entities controlled by Daniel Roberts and William Roberts, respectively. The B Class shares were formally issued on 7 October 2021. Each B Class share confers on the holder fifteen votes for each ordinary share in the Company held by the holder. In addition, a B Class share confers a right for the holder to nominate a director to put forward for election to the Board. Because of the increased voting power of the B Class shares, the holders of the B Class shares collectively could continue to control a significant percentage of the combined voting power of the Company’s shares and therefore be able to control all matters submitted to the Company’s shareholders for approval until the redemption of the B Class shares by the Company on the earlier of (i) when the holder ceases to be a director due to voluntary retirement; (ii) a transfer of B Class shares in breach of the Constitution; (iii) liquidation or winding up of the Company; or (iv) at any time which is 12 years after the Company’s ordinary shares are first listed on a recognized stock exchange. Aside from these governance rights, the B Class shares do not provide the holder with any economic rights (e.g. the B Class shares do not confer on its holder any right to receive dividends). The B Class shares are not transferable by the holder (except in limited circumstances to affiliates of the holder).
