Binding hardware purchase contracts with Bitmain
Company: IREN
What the later record shows
Partly delivered
The Bitmain contracts were wound up with miners either 'delivered and installed, or on-sold to third parties'. Only about 5.6 EH/s was operating at June 30, 2023, so the 14.5 EH/s scope and the 15.2 EH/s total were not reached under these contracts. The remainder was on-sold rather than left pending.
“There are no remaining commitments under these agreements and all miners have since been delivered and installed, or on-sold to third parties.”
