Exhibit 99.1

Soluna Expands Partnership with Blockware by Over 50% at Project Dorothy 2

Now Totaling 8 MW of Sustainable Hosting Capacity

ALBANY, NY, June 18, 2025 – Soluna Holdings, Inc. (“Soluna” or the “Company”), (NASDAQ: SLNH), a developer of green data centers for intensive computing applications, including Bitcoin mining and AI, today announced that it has signed a hosting expansion agreement with Blockware, one of North America’s leading crypto mining infrastructure and services providers.

Following their initial 5 megawatt (MW) deployment in April, Blockware is adding 3 MW of hosting capacity at Soluna’s Project Dorothy 2 data center in Texas, bringing their total contracted footprint at the site to 8 MW.

The expansion underscores the strength of the partnership and the quality of execution on both sides. In just two months, Blockware’s team saw the value of Soluna’s vertically integrated, renewable-powered infrastructure and moved quickly to secure additional capacity ahead of growing market demand.

“We’re excited to deepen our relationship with Blockware,” said John Belizaire, CEO of Soluna Holdings. “This expansion is a testament to the trust we’ve built together and a reflection of the momentum our Project Dorothy platform is generating in the market. We’re proud to be the partner Blockware chooses to scale with.”

Soluna’s data center projects offer a cost-effective, sustainable environment for high-performance Bitcoin mining. As part of the agreement, Soluna continues to provide full-stack infrastructure, including power management, data center operations, and on-site support.

“Blockware is proud to continue building alongside Soluna, expanding from our initial 5MW deployment with an additional 3MW of capacity,” says Kentaro Masuda, Chief Operating Officer, Blockware. “The first phase has consistently delivered reliable uptime and operational efficiency, validating both the site and the partnership. This partnership with Soluna enhances the Blockware Marketplace by increasing the supply of next-generation ASICs, making profitable and efficient Bitcoin mining accessible to everyone.”

Blockware’s total deployment at Dorothy 2 now represents up to 8 MW and an estimated 450-550 PH/s of hashrate powered by renewable energy, further advancing both companies’ commitment to sustainable blockchain infrastructure in the United States.
