ALBANY, NY - November 13, 2025- Soluna Holdings, Inc. ("Soluna" or the "Company") (NASDAQ: SLNH), a developer of green data centers for intensive computing applications, today announced the completion and full energization of Project Dorothy 2, the 48 MW second phase of its flagship Project Dorothy in West Texas.

With this milestone, the 100 MW Project Dorothy campus is now fully operational - delivered on time and on budget - bringing Soluna's total energized data center capacity to 123 MW and over 5 EH/s, a 73.3% increase since April 2025.

"Dorothy 2 represents disciplined execution and a major step forward for Soluna," said John Belizaire, CEO of Soluna. "Our team delivered a complex, large-scale project on schedule, proving that Renewable Computing can be deployed quickly, reliably, and sustainably. It's exciting to be growing again."

Built behind the meter at a 150 MW wind farm, Project Dorothy converts curtailed renewable energy into productive computing power for Bitcoin mining and AI. The site's modular design enables rapid scaling while maintaining operational efficiency and flexibility.

Powered by Soluna's proprietary MaestroOS™ platform, the site leverages intelligent monitoring, precise data, and full-stack automation to enable faster decisions, higher uptime, and seamless grid integration.

Project Dorothy 2 Highlights:

Energized in three construction phases, each delivered on time and on budget
Early revenue generation began within six months of groundbreaking
Now Soluna's highest-performing site, managing over 2 EH/s independently

The transition to full operations for Projects Dorothy 1 and 2 has created 18 full-time local jobs, as well as additional indirect roles supporting maintenance, logistics, and services across the region.

With Project Dorothy 2 fully online, Soluna continues to advance its 1 GW+ of Renewable Computing projects, including 166 MW Project Kati, currently under construction. Each site is designed to transform underutilized renewable energy into scalable, sustainable computing infrastructure for the world's fastest-growing digital workloads, including Bitcoin mining and AI.

Soluna continues its tradition of naming its data centers after women scientists who help catalyze major innovation. Project Dorothy is named after Dorothy Vaughan, an African American mathematician and "human computer" who worked for the National Advisory Committee for Aeronautics and NASA in 1939, exemplifying innovation and excellence in computing.
