Industry Context

Soluna's focus on developing green data centers for intensive computing applications like Bitcoin mining and AI positions it at the intersection of two rapidly growing, energy-intensive industries. The achievement of 1 GW in renewable-powered computing capacity demonstrates a commitment to sustainable infrastructure, a key differentiator in an industry facing increasing scrutiny over energy consumption. The expansion of partnerships with institutional players like Galaxy Digital suggests a maturing market for large-scale, green hosting solutions.

Comparison to Industry Standards

• The achievement of 1 GW in renewable-powered computing capacity places Soluna among the larger players in the green data center and Bitcoin mining infrastructure space, comparable to companies like Marathon Digital Holdings or Riot Platforms in terms of scale, but with a distinct emphasis on renewable energy integration.
• The expanded partnership with Galaxy Digital, a prominent financial services and investment management company in the digital asset sector, for a 48 MW deployment at Project Kati 1, indicates strong institutional confidence in Soluna's hosting capabilities, similar to how other large-scale miners or hosting providers secure significant contracts with major industry participants.

• Employees: Potential for increased job opportunities and stability as the company expands its project portfolio and operational footprint.
• Local Communities: Project development (e.g., Project Kati) involves civil construction and infrastructure upgrades, potentially creating local employment and economic activity, while the focus on renewable energy aligns with environmental goals.

Next Steps

• Continue development activities for Projects Rosa, Hedy, Ellen, Annie, Gladys, and Fei, focusing on PPA negotiations, ERCOT planning, and land acquisition.
• Complete Phase 3 construction for Project Dorothy 2 by the end of October 2025, with commissioning activities beginning mid-September.
• Energize Project Kati 1 by December 2025, following ongoing civil construction and substation interconnection work.
