S21 and T21 miners shipment
Company: IREN
What the later record shows
Delivered; the record does not say when
Later filings say all S21 miners (October 2023 agreement) and all T21 miners (November 2023 agreement) were delivered in full. They do not say when, so it cannot be told whether shipment was in Q1 2024.
“All Bitmain S21 miners under this purchase contract have been delivered in full.”
