Technical commentary

The Company’s average operating hashrate was marginally higher this month (5,554 PH/s vs. 5,493 PH/s in August). The decrease in Bitcoin mined (390 vs. 410 in August) was primarily attributable to an increase in network difficulty and one less day during the month. The increase in electricity costs per Bitcoin ($13.7k vs. $10.6k in August) was primarily attributable to lower energy trading proceeds at Childress, however this resulted in a higher operating hashrate for the month.

1 All timing references in this investor update are to calendar months, in each case unless otherwise specified.2 Bitcoin and Bitcoin mined in this investor update are presented in accordance with our revenue recognition policy which is determined on a Bitcoin received basis (post deduction of mining pool fees as applicable). Electricity costs exclude REC purchases.3 The Company’s Childress site generated ~US$948k of power sales in September (~36 Bitcoin equivalent), which represents unaudited power credits (primarily driven by voluntary curtailment) under hedge contracts (based on current meter data and ERCOT real-time prices) and are reflected within the electricity costs. Figures are based on current internal estimates and exclude REC purchases.4 Reflects average all-in power price achieved at Childress between May 2023 and August 2023 (based on monthly electricity invoices received as well as internal estimates). Excludes April 2023 as this represented a partial period (reflecting initial ramp-up in operations). Excludes costs of purchasing RECs. Includes basis costs, ERCOT, retail and network fees, net of estimated power credits. There is no guarantee similar power credits will be achieved at Childress in the future (or at all). Includes internally estimated value of current enrolment in ERCOT’s Emergency Response Service program (“ERS”) for the period between June 2023 and August 2023 (based on actual observed ERS clearing prices during the period). Childress has not yet received any ERS benefit and there is no guarantee it may receive any benefit (e.g. due to unsuccessful participation) and ERCOT has not confirmed the value of the ERS benefit under the current enrolment (if any). Includes internally estimated value from load reduction to reduce four coincident peak (“4CP”) transmission network charges. Childress is not eligible to receive the 4CP benefit in its first calendar year of operations (2023), however it is currently anticipated Childress may be eligible to receive the benefit from the start of 2024. The internally estimated value of the benefit is based on actual 4CP peak demand at Childress between June 2023 and August 2023 and internally estimated 4CP peak demand for September 2023. Childress has not yet received any 4CP benefit and there is no guarantee it will receive any benefit (e.g. due to unsuccessful participation) and AEP has not confirmed the value of any 4CP benefit to date (if any). The actual all-in-power price achieved at Childress may differ materially in the future, including due to energy market volatility and seasonal factors (noting the site has only operated since April 2023).5 Illustrative potential Iris Energy hashrate if Childress is fully built-out to 600MW (i.e. 760MW of Company aggregate power capacity). Assumes purchase of Bitmain S19 XP miners. Additional miners have not yet been purchased and the Company will continue to monitor the market for funding and purchase opportunities. Hashrate figures may change depending on miner procurement selection. There can be no assurance that Iris Energy will be able to procure additional miners on the anticipated schedule or at all, or on terms that are favorable to Iris Energy.6 Reflects average all-in power price achieved at Childress between May 2023 and August 2023 (based on monthly electricity invoices received as well as internal estimates). Note, the power price at Childress in September 2023 was ~1.8c/kWh (based on internal estimates). Excludes April 2023 as this represented a partial period (reflecting initial ramp-up in operations). Excludes costs of purchasing RECs. Includes basis costs, ERCOT, retail and network fees, net of estimated power credits. There is no guarantee similar power credits will be achieved at Childress in the future (or at all). Includes internally estimated value of current enrolment in ERCOT’s Emergency Response Service program (“ERS”) for the period between June 2023 and August 2023 (based on actual observed ERS clearing prices during the period). Childress has not yet received any ERS benefit and there is no guarantee it will receive any benefit (e.g. due to unsuccessful participation) and ERCOT has not confirmed the value of the ERS benefit under the current enrolment (if any). The actual all-in-power price achieved at Childress may differ materially in the future, including due to energy market volatility and seasonal factors (noting the site has only operated since April 2023).7 Illustrative electricity cost per Bitcoin at Childress based on 2.0c/kWh and 1.4c/kWh respectively, assuming 388 EH/s difficulty-implied global hashrate, 6.25 BTC block reward per block and 0.20 BTC transaction fees per block.8 As of June 30, 2023.9 In addition to the $300m ATM, the shelf filing includes capacity for up to an additional $200m of other securities (e.g. debt, hybrid and/or equity). Sales of any securities under the ATM or otherwise are subject to market conditions and there are no assurances all or any portion of such securities will be sold.10 The Company’s Canal Flats, Mackenzie and Prince George sites have been powered by 100% renewable energy since inception of which approximately 98% is directly from renewable energy sources; approximately 2% is from the purchase of RECs. The Company’s Childress site has been powered by 100% renewable energy since inception via the purchase of RECs.11 Comprises actual power usage for Canal Flats, Mackenzie, Prince George and Childress.12 Reflects estimated hashrate capacity by site assuming full utilization of existing available data center capacity with Bitmain S19j Pro miners, except where otherwise stated.13 Assumes purchase of Bitmain S19 XP miners. Additional miners have not yet been purchased and the Company will continue to monitor the market for funding and purchase opportunities. Hashrate figures may change depending on miner procurement selection. There can be no assurance that Iris Energy will be able to procure additional miners on the anticipated schedule or at all, or on terms that are favorable to Iris Energy.14 Indicative timing for commencement of delivery of data centers.
