Barber Lake property exclusive arrangement with SoftBank
Company: Cipher Mining - Project: Barber Lake Facility
What the later record shows
Outcome not yet confirmed
No passage mentions SoftBank or any Barber Lake sale, transfer or encumbrance before February 28, 2025. The Fluidstack lease (September 24, 2025) came after the exclusivity window, so it says nothing about compliance.
