IREN

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 announced that its 160MW of data center capacity is not affected by the recent announcement by the Government of British Columbia.

On December 21, 2022, the Government of British Columbia announced a temporary 18-month suspension on new and early stage BC Hydro connection requests from cryptocurrency mining projects due to unprecedented interest1.

According to the release, cryptocurrency mining projects that are operational, and a small number of projects that are well advanced in BC Hydro’s connection process, will not be affected.

As a result, the Company’s 160MW of data center capacity at Canal Flats (30MW), Prince George (50MW) and Mackenzie (80MW) is unaffected.

Iris Energy looks forward to continuing to work with BC Hydro and local communities in respect of its existing data centers and any additional development projects the Company may pursue in the future. In parallel, construction of the first 20MW data center at its 600MW project in Childress, Texas remains on track, with the Company continuing to progress development works across its globally diversified pipeline of future sites.

This investor update includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally relate to future events or Iris Energy’s future financial or operating performance. For example, forward-looking statements include but are not limited to, the Company’s expected power capacity and operating capacity, and the impact of an event of default and/or acceleration of amounts due under limited recourse equipment financing arrangements in the Company’s special purpose vehicles. In some cases, you can identify forward-looking statements by terminology such as “anticipate,” “believe,” “may,” “can,” “should,” “could,” “might,” “plan,” “possible, ”project,” “strive,” “budget,” “forecast,” “expect,” “intend,” “target”, “will,” “estimate,” “predict,” “potential,” “continue”, ”scheduled” or the negatives of these terms or variations of them or similar terminology, but the absence of these words does not mean that statement is not forward-looking. Such forward-looking statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward looking statements. In addition, any statements or information that refer to expectations, beliefs, plans, 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 and beliefs. These statements are neither promises nor guarantees, but involve known and unknown risks, uncertainties and other important factors that may cause Iris Energy’s actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements, including, but not limited to: Iris Energy’s limited operating history with operating losses; electricity outage, limitation of electricity supply or increase in electricity costs; long term outage or limitation of the internet connection at Iris Energy’s sites; any critical failure of key electrical or data center equipment; serial defects or underperformance with respect to Iris Energy’s equipment; failure of suppliers to perform under the relevant supply contracts for equipment that has already been procured which may delay Iris Energy’s expansion plans; supply chain and logistics issues for Iris Energy or Iris Energy’s suppliers; cancellation or withdrawal of required operating and other permits and licenses; customary risks in developing greenfield infrastructure projects; Iris Energy’s evolving business model and strategy; Iris Energy’s ability to successfully manage its growth; Iris Energy’s ability to raise additional financing (whether because of the conditions of the markets, Iris Energy’s financial condition or otherwise) on a timely basis, or at all, which could adversely impact the Company’s ability to meet its capital commitments (including payments due under its hardware purchase contracts with Bitmain) and the Company’s growth plans; Iris Energy’s failure to make certain payments due under any one of its 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 failure of Iris Energy’s wholly-owned special purpose vehicles to make required payments of principal and/or interest under their limited recourse equipment financing arrangements when due or otherwise comply with the terms thereof, as a result of which the lender thereunder has declared the entire principal amount of each loan to be immediately due and payable, and while no assurance can be provided as to what actions may be taken, we expect such lender will take steps to enforce the indebtedness and its rights in the Bitcoin miners with respect to certain of such loans (and potentially all such loans) and other assets securing such loans, which would result in the loss of the relevant Bitcoin miners securing such loans and materially reduce the Company’s operating capacity, and could also lead to bankruptcy or liquidation of the relevant special purpose vehicles, and materially and adversely impact the Company’s business, operating expansion plans, financial condition, cash flows and results of operations; the terms of any additional financing or any refinancing, restructuring or modification to the terms of any existing 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, global hashrate and the market value of Bitcoin miners, any of which could adversely impact the Company’s financial condition, cashflows and results of operations, as well as its ability to raise additional financing and the ability of its wholly-owned special purpose vehicles to make required payments of principal and/or interest on their equipment financing facilities; risks related to health pandemics including those of COVID-19; changes in regulation of digital assets; and other important factors discussed under the caption “Risk Factors” in Iris Energy’s Annual Report on Form 20-F for the fiscal year ended June 30, 2022 filed with the SEC on September 13, 2022, as such factors may be updated from time to time in its other filings with the SEC, accessible on the SEC’s website at www.sec.gov and the Investor Relations section of Iris Energy’s website at https://investors.irisenergy.co.

These and other important factors could cause actual results to differ materially from those indicated by the forward-looking statements made in this investor update. Any forward-looking statement that Iris Energy makes in this investor update speaks only as of the date of such statement.
