[Cipher Agrees to Bear Approximately $359 Million Over-Budget Cost of Barber Lake First Floor] BlockBeats reported on November 6th, citing Miner Weekly, that one of the more indicative figures in Cipher Mining's quarterly financial report appeared in the lease notes: the company has agreed to initially bear $359.3 million in over-budget costs for the first floor of the Barber Lake project under a revised lease arrangement. Beyond this threshold, the tenant will share half of the additional costs with extra rent over the combined 20-year contract period, with corresponding returns agreed upon. This figure is a contract threshold, not the final total amount of the project's over-budget costs, but it highlights the issue of who will bear the increased delivery costs after the AI lease is signed. Cipher management stated that both parties were eager to move forward, and the lease was signed before the design was fully developed. There were more change orders than expected, and modifications to cooling facilities and other aspects increased construction work and disrupted other processes. Other issues included lower-than-expected productivity, equipment delays, and idle time, while the increased cost of the equipment itself was not the primary cause. The company stated that next-generation leases will be signed only after approximately 30%–60% of the design is complete. Riot Platforms also discussed industry cost overruns and the Rockdale budget, stating that about 70% of the total budget is expected to be included in the general contractor's guaranteed maximum price framework, and maintaining an estimate of approximately $11 million–12 million per critical IT megawatt; under the new arrangement for Corsicana, tenant procurement and modular deployment are estimated by Riot to be approximately $6 million per megawatt after tenant reimbursements and site works. Core Scientific disclosed approximately $4.4 billion in outstanding procurement and construction commitments, of which almost all modifications related to CoreWeave are funded by customers with capped company contributions, while AMD and Neocloud expansions have no similar protection.
