IREN Iris Energy Ltd

Iris Energy Limited (NASDAQ: IREN) (together with its subsidiaries, “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, 2023. All $ amounts are in United States Dollars (“USD”) unless otherwise stated.

“FY23 was a transformational year for Iris Energy”, stated Daniel Roberts, Co-Founder and Co-Chief Executive Officer of Iris Energy. “We increased our operating hashrate to 5.6 EH/s but importantly also expanded our power capacity to an industry-leading 760MW, thereby activating an expansion pathway to 30 EH/s. We also remain excited by our next-gen compute and generative AI strategy, providing an additional potential growth area for the Company.”

Full Year FY23 Financial Results

• Record Bitcoin mining revenue of $75.5 million, as compared to $59.0 million in fiscal year 2022, primarily driven by increase in number of Bitcoin mined, partially offset by a decrease in the Bitcoin price
• Record 3,259 Bitcoin mined, as compared to 1,399 Bitcoin mined in fiscal year 2022, primarily driven by growth in operating hashrate
• Electricity costs of $35.8 million, as compared to $11.0 million in fiscal year 2022, primarily driven by growth in operating hashrate, with 3 new sites commissioned during the year
• Other costs of $38.3 million, as compared to $21.8 million in fiscal year 2022. Cost base reflects materially expanded business with growth beyond existing 5.6 EH/s
• Net loss after income tax of $171.9 million, as compared to a $419.8 million loss in fiscal year 2022. The decrease in net loss after income tax primarily reflects impact of non-cash mark-to-market of convertible instruments converted into equity at IPO during the prior period
• Non-cash impairment charge of $105.2 million recorded in fiscal year 2023, primarily relating to the limited-recourse financing SPVs and impairment of mining hardware. The limited-recourse financing SPVs were deconsolidated on February 3, 2023 with the appointment of the Receiver
• Adjusted EBITDA of $1.4 million as compared to $26.2 million in fiscal year 20221
• $68.9 million cash and cash equivalents as of June 30, 2023 and no debt facilities2

Key Operational and Corporate Highlights:

• Increased self-mining operating capacity by 380% from 1.2 EH/s to 5.6 EH/s3
• Announced 9.1 EH/s expansion plan and revitalization of HPC strategy
• Expanded available power capacity from 80MW to 760MW across the platform (180MW operating)
  • Energized additional 30MW at Mackenzie and 50MW at Prince George
  • Energized 600MW at Childress (20MW operating)
• Appointed Raymond Chabot Grant Thornton LLP as the Company’s auditor

Non-IFRS Financial Measures

This press 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.

EBITDA is calculated as our IFRS profit/(loss) after income tax expense, excluding interest income, finance expense and non-cash fair value loss and interest expense on hybrid financial instruments, income tax expense, depreciation and amortization, which are important components of our IFRS profit/(loss) after income tax expense. Further, “Adjusted EBITDA” also excludes share-based payments expense, which is an important component of our IFRS profit/(loss) after income tax expense, impairment of assets, loss on other receivables, loss on disposal of assets, foreign exchange gains and losses and other one-time expenses and income.
