Soluna Achieves Record Low Power Costs Paving the Way for AI Computing at Project Dorothy

Offers Comprehensive Updates on Company and Project Sites; Launches new data center design program

Soluna Holdings, Inc. (“SHI” or the “Company”), (NASDAQ: SLNH), the parent company of Soluna Computing, Inc. (“SCI”), a developer of green data centers for Bitcoin mining and other intensive computing applications, announced today detailed company and site level updates, including its record low power costs being realized in October at its Project Dorothy 1 site, and its plans to include a high performance computing and AI pilot as part of Project Dorothy 2.

John Belizaire, CEO of Soluna Holdings, commented, “Our business fundamentals continue to improve. We are proud to say that we are executing well against our plan. Project Dorothy 1 is now fully operational and our costs are optimized. Our technology, data centers and MaestroOS software, is working as planned, and we are poised to take advantage of the exploding AI market. This is beginning to attract new strategic partners. I want to thank our investors who have been patient with us and are with us for the long haul.”

The Company has provided the following Corporate and Site Updates.

Corporate Highlights:

• Project Dorothy 2 Plans to include AI - Site layout finalized for an initial phase of the second 50 MW of Project Dorothy. Equipment specification bids have been obtained. Financing is being finalized for an initial 16 MW phase, to begin in the first half of 2024, and will include a scalable pilot for high performance computing which Soluna expects will be used to run AI workloads for future customers.

• AI Data Center Design Underway – The company has been working with new strategic partners to design and upgrade its existing data center design to more specifically address the needs of generative AI training workloads – codenamed internally as “Helix.” The company believes the overwhelming unmet demand for power and computing space in the AI field will allow Soluna to transform its super low cost computing infrastructure to meet AI’s exponentially growing needs. Soluna’s data centers and proprietary MaestroOS software have been designed for this opportunity since inception. As Soluna converts its asset base to be AI-centric, it expects to offer its AI customers purpose-built facilities powered by renewable energy at ground breaking costs.

• Curtailment Solution Hits Record- Soluna has exceeded the expectations of its wind farm partners by monetizing over 4,000 MWh of curtailed (wasted) energy. That’s enough energy to charge a typical smartphone 1 billion times. Soluna has demonstrated that when coupled with a wind farm, 100% of generated energy is monetized. This improves the economics of our wind farm partners and helps to put more renewables on the grid.

• Power Costs Hit Record Levels – Project Dorothy has been experiencing record low power costs in October of less than $26/MWh level without ancillary services.*

• Project Sophie Moving to More Profitable Customers - 60% of the site is being transitioned to new customers, and more profit. The Company is expanding its relationships with leading bitcoin miners in the market.

• Inched closer to launching Ancillaries – The company is on track to complete its registration for ERCOT Ancillary services market in Q1.

• Soluna CTO Attends Water Tower Research Fireside Chat - Dip Patel, CTO of Soluna Computing, gave an update on Project Dorothy (Phase 1), and an in depth look at Soluna's Modular Data Centers, including performance of its proprietary software, MaestroOS. The energizing discussion can be viewed here.

• Pipeline Continues to Grow – Over 250 MW was added to Soluna’s long term pipeline.
