## Exhibit 99.1

**Exhibit 99.1**

**Soluna Expands Partnership with Galaxy Digital to Deploy 48 MW at Project Kati**

*New deployment— largest to date—secures its first operational partner at Project Kati 1, expands to 83 MW, and is construction-ready to launch.*

**ALBANY, NY, August 12, 2025** – <u>Soluna Holdings, Inc</u>. ("Soluna" or the "Company"), (NASDAQ: SLNH), a developer of green data centers for intensive computing applications, including Bitcoin mining and AI, announced today an expanded partnership with <u>Galaxy Digital</u> Inc. ("Galaxy") (NASDAQ/TSX: GLXY), a global leader in digital assets and datacenter infrastructure. Under the new agreement, Galaxy will deploy proprietary bitcoin mining operations – previously housed at their Helios datacenter campus in the Texas panhandle – at a 48 MW expansion of Soluna's Project Kati 1 in Texas. **The expansion brings Project Kati 1 to its full capacity of 83 MW and, having cleared tax abatement approvals, construction is expected to launch before the end of August**.

Soluna <u>previously entered into a $5 million loan facility</u> with Galaxy in Q1 2025. With this new deployment, the partnership extends into an operational collaboration.

Project Kati 1 is currently expected to be operational in Q1 2026. This expansion marks Soluna's largest deployment of a single partner to date, following a recent 30 MW rollout with another Top-Tier Bitcoin miner. Galaxy will be the first customer to begin mining operations at Project Kati 1 once construction is complete.

"As demand from hyperscaler miners continues to surge, Soluna is scaling to meet the moment," said John Belizaire, CEO of Soluna. "This partnership with Galaxy represents our largest MW deployment to date and underscores how our modular approach allows us to deliver efficient, renewable-powered infrastructure at scale. We're proud to deepen our relationship with Galaxy and help power the next wave of computing."

Key Deal overview:

● 48 MW of hosting of Galaxy Bitcoin mining containers and miners

● Deployment expected 1Q26 and 2Q26

● Turnkey power infrastructure and operations provided by Soluna

"As we transition our Helios campus to an AI and high-performance computing data center, we're pleased to relocate a portion of our existing Bitcoin mining assets to Soluna to manage," said Sam Kiernan, Business Development Lead at Galaxy.

The company expects that this expansion will bring Soluna's operating capacity to 206 MW once fully deployed.
