Acceleration of Bitmain miner delivery
Company: Cipher Mining
What the later record shows
Delivered; the record does not say when
A May 2025 filing refers to payment obligations for machines delivered in 2024. The August 2025 10-Q says all miners under the agreement were delivered. Neither confirms the September/October 2024 timing.
“Approximately $27 million of the Revised Payment Amount will satisfy remaining payment obligations in respect of machines delivered in 2024.”
