Bitcoin miner Iris Energy will nearly triple hashrate after buying 4.4 EH/s in machines

Quick Take

  • Iris energy bought 4.4 EH/s in machines using Bitmain prepayments.
  • As they get installed in the coming months, the new machines will bring the company’s hashrate back up to 5.5 EH/s — above last year’s levels, before it unplugged machines used as loan collateral.
  • It currently has 1.7 EH/s miners online and 0.3 EH/s in transit or pending deployment.

Bitcoin miner Iris energy bought 4.4 EH/s worth of machines with $67 million in Bitmain prepayments and now expects to nearly triple its hashrate.

The company turned off about 3.6 EH/s worth of machines collateralizing over $100 million in loans in November after getting a default notice from its lender.

The new miners (S19j Pro) will be installed "over the coming months" and bring Iris's hashrate up to 5.5 EH/s, the company said.

"This is a significant milestone for Iris Energy. We are delighted to have been able to utilize our remaining Bitmain prepayments to acquire new miners without any additional cash outlay," said co-founder and co-CEO Daniel Roberts.

The company is also considering selling any surplus miners over 5.5 EH/s of self-mining capacity "to re-invest in growth initiatives and/or corporate purposes."

Iris is debt free after extinguishing its loans at the end of last year.

The firm said in November that given mining economics, the machines used as collateral weren't making enough money to pay for loans, generating around $2 million in BTC per month in gross profit, versus the $7 million in debt obligations.

"The facilities were intentionally structured for prudent risk management to protect the underlying business and data center infrastructure the Group has built (i.e., without a parent company guarantee and without recourse to any other Group entities)," the firm said.
