Industry Context

This announcement positions Cipher Mining as a significant player in the rapidly growing high-performance computing (HPC) and AI data center market. The expansion of capacity and long-term agreements with key partners like Fluidstack and Google reflect the increasing demand for specialized infrastructure to support AI workloads. The high NOI margin suggests efficient operations in a capital-intensive industry, while Google's expanded backstop highlights the strategic importance and financial viability of such partnerships in the competitive data center landscape.

Comparison to Industry Standards

• The expected Site Net Operating Income (NOI) Margin of 85%-90% is exceptionally high compared to typical data center industry benchmarks, which often range from 50-70% for colocation facilities. This indicates strong operational efficiency and favorable lease terms for Cipher Mining.
• The estimated project costs of approximately $9-$10 million per MW of critical IT load are within the higher end of the industry range for advanced HPC data centers, reflecting the specialized infrastructure required for such operations.
• Google's substantial financial backstop of $1.73 billion for Fluidstack's lease obligations is a significant differentiator, providing a level of credit enhancement rarely seen in standard colocation agreements and demonstrating Google's commitment to the partnership and the underlying asset.

Related Party Transactions

• Google LLC is a party to the Amended and Restated Warrant Agreement and the Amended and Restated Recognition Agreement, providing a significant guarantee for Fluidstack's obligations and holding warrants for Cipher Mining's common stock.

Stakeholder Impact

• Shareholders: Positive impact due to increased contracted revenue, expanded capacity, strong profitability margins, and significant financial backing from Google, which de-risks the project and supports future growth.
• Customers (Fluidstack): Benefits from expanded critical IT load capacity and Google's guarantee, ensuring project completion and operational stability.
• Lenders: The proposed senior secured notes offering is attractive due to the first-priority liens on assets and the pledge of warrants by Google, enhancing security.
• Employees: Potential for job creation and stability related to the development and operation of the expanded data center facility.

Next Steps

• Completion and delivery of Phase I of the Barber Lake Facility to Fluidstack by September 2026.
• Completion and delivery of Phase II of the Barber Lake Facility to Fluidstack by January 2027.
• Cipher Compute LLC's proposed offering of $333 million in additional senior secured notes due 2030.
