Second Quarter FY24 Financial Results

“The business has continued to strengthen its position and execute upon significant planned expansion in 2024,” stated Daniel Roberts, Co-Founder and Co-Chief Executive Officer of Iris Energy.

“Our Bitcoin mining hashrate is on track to reach 10 EH/s over the coming months and 20 EH/s by the end of the year. Our AI cloud services business continues to outperform expectations and recently tripled in size with another significant purchase order for NVIDIA H100 GPUs. We also continue to remain excited about our new 1,400MW data center development site in West Texas, which should provide substantial growth potential for years to come.”

  • Bitcoin mining revenue of $42.0 million, as compared to $34.4 million in the first quarter of fiscal year 2024, primarily driven by an increase in average Bitcoin price realized
  • Mined 1,144 Bitcoin, as compared to 1,223 Bitcoin in the first quarter of our fiscal year 2024. Lower Bitcoin production was primarily driven by higher global hashrate rate during the period

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.
