The company anticipates continued growth in this sector, driven by the increasing demand from Tier 1 hyperscalers for data center capacity, particularly in non-traditional areas like Texas. Future plans include delivering 300 MW of AI capacity to AWS in 2026 and energizing the 1-gigawatt Colchis site in West Texas by 2028, with a total pipeline of 3.2 GW of site capacity.

Management Comments

• CEO Tyler Page stated that the third quarter was 'truly transformative' for Cipher.
• Page highlighted that the pivotal transaction with Fluidstack and Google 'firmly established our credibility in the HPC space'.
• He noted that signing the direct lease with a Tier 1 hyperscaler like AWS is 'another major step forward'.
• Page expressed confidence that Cipher is 'among the best-positioned companies in the world to seize additional opportunities created by the growing power shortfall' as the industry evolves and validates their thesis regarding hyperscalers turning to Cipher and Texas.

Industry Context

This announcement positions Cipher Mining as a significant player in the rapidly evolving data center industry, particularly at the intersection of cryptocurrency mining and High-Performance Computing (HPC) for AI workloads. The shift towards providing infrastructure for AI aligns with broader industry trends where demand for specialized, high-power data centers is surging due to the exponential growth of AI and machine learning. By securing major contracts with 'Tier 1 hyperscalers' like Amazon Web Services and Google (via Fluidstack), Cipher is capitalizing on the 'growing power shortfall' faced by traditional data center providers, leveraging its expertise in large-scale power infrastructure development in regions like Texas.

Comparison to Industry Standards

• The 15-year, $5.5 billion lease with Amazon Web Services for 300 MW of AI capacity is a substantial contract, comparable in scale and duration to agreements seen with leading data center REITs or specialized AI infrastructure providers.
• The development of a 1-gigawatt site like Colchis, supported by a Direct Connect Agreement with American Electric Power, positions Cipher among a select group of companies capable of delivering hyperscale power solutions, a critical need for the largest cloud and AI companies.
• The company's strategy to pivot towards AI/HPC hosting, with a pro-forma capacity mix of approximately 67% AI/HPC and 33% Bitcoin mining, reflects a proactive adaptation to market demands, similar to how other energy-intensive data center operators are diversifying their revenue streams.

Related Party Transactions

• Receivables, related party, amounted to $308,000 as of September 30, 2025, down from $2,090,000 as of December 31, 2024.

Stakeholder Impact

• **Shareholders**: Significant potential for increased shareholder value due to large, long-term contracts with Tier 1 hyperscalers and substantial capacity expansion, backed by a strong capital raise.
• **Employees**: Growth in operations and strategic diversification likely create new opportunities and job stability within the company.
• **Customers (AWS, Fluidstack/Google)**: Benefit from Cipher's ability to provide large-scale, specialized data center infrastructure for critical AI workloads.
• **Suppliers/Partners (AEP)**: Strengthened relationships and potential for future collaborations through large-scale infrastructure projects like the Colchis site.
• **Creditors**: The successful $1.3 billion convertible note offering indicates strong market confidence and provides substantial liquidity, enhancing the company's financial stability.

Next Steps
