IREN IREN Ltd

Iris Energy Limited (NASDAQ: IREN) (together with its subsidiaries, “IREN”) today provided a business update.

AI Operations Scaling with Strong Profit Contribution

IREN’s AI Cloud Services division is expected to be generating approximately $32 million in annualized hardware profit by the end of December 2024, contributing approximately 10% to the company’s overall earnings.1

Key updates include:

• GPU Utilization: The company’s current fleet of 816 NVIDIA H100 GPUs is nearing full utilization, with pending contracts expected to cover the remaining capacity.
• Expansion Plans: IREN is set to commission an additional 1,080 NVIDIA H200 GPUs in Q4 2024, more than doubling its existing AI capacity.
• Immediate Scalability: AI Cloud Services currently utilize less than 0.5% of IREN’s total data center capacity, providing ample room to scale as additional customer contracts are secured.2

• Next-Generation GPUs: Design and procurement underway to accommodate liquid-cooled hardware, including NVIDIA Blackwell GB200 GPUs, in existing Prince George and Childress data centers.

1.4GW Data Center Project Update

• Accelerated Timeline: The target energization date for IREN’s 1.4GW substation at its West Texas data center project has been brought forward to April 2026, earlier than the originally contracted date of October 2026.
• Key Electrical Items: IREN has engaged an EPC contractor to develop its high and medium-voltage substation infrastructure. Ongoing work on design & specifications continues, with the procurement process underway for the following key electrical items:
  • Four x 560MVA 345kV/138kV transformers, supporting 1,400MW of bulk power substation capacity, with redundancy and potential for future expansion.
  • Eight x 138kV/35kV transformers, supporting 1,400MW of primary substation capacity.
  • Various 345kV and 138kV circuit breakers and other ancillary equipment.
• Land Expansion: IREN has secured 800 additional acres of land, adding to its existing 500 acres of freehold land, bringing the total landholding to over 1,300 acres.
• Monetization: Planning is underway for both Bitcoin mining and HPC/AI pathways, with indicative interest from hyperscalers and other interested parties.

Assumptions and Notes

1. Refers to proportion of illustrative annualized exit run-rate hardware profit at the end of 2024 for AI Cloud Services ($32m) relative to Bitcoin Mining ($317m), calculated as illustrative revenue less assumed electricity costs (excludes all other site, overhead and Renewable Energy Certificate (“REC”) costs). Calculations assume hardware operates at 100% uptime. AI Cloud Services calculations assume 1.25kW power draw per GPU, $0.045/kWh electricity costs and lower end of a $2.00 - $2.50 per GPU hour revenue assumption range. Bitcoin mining calculations assume $60,000 (Bitcoin price), 658 EH/s (global hashrate), 3.125 BTC (block reward), 0.1 BTC (transaction fees), 0.15% (pool fees), 484MW (power consumption), $0.038/kWh electricity costs (4.5c/kWh BC, 3.5c/kWh Childress).
2. Assumes 1.25kW power draw per GPU, 510MW of operating data center capacity (by end of 2024) and 1,896 NVIDIA H100 and H200 GPUs.
