Bitcoin Mining as a Service (BMaaS) financial
"a partnership with Sazmining, a pioneer in Bitcoin Mining as a Service (BMaaS)."
Cumulative Perpetual Preferred Stock financial
"9.0% Series A Cumulative Perpetual Preferred Stock, par value $0.001 per share"
A cumulative perpetual preferred stock is a share that acts like a long-lasting hybrid between a bond and a dividend-paying stock: it promises regular fixed payments that, if missed, accumulate and must be paid later before common shareholders get dividends, and it has no set maturity date. Investors care because it can provide steady, higher-priority income similar to interest, but with limited capital upside, sensitivity to interest rates, and the risk that payments can be delayed even though they continue to accrue.
forward-looking statements regulatory
"This press release contains forward-looking statements."
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
safe harbor regulatory
"These statements are made under the “safe harbor” provisions of the U.S. Private Securities Litigation Reform Act of 1995."
Safe harbor is a rule that protects companies or individuals from legal trouble if they follow certain guidelines or procedures. It’s like having a safety net that allows them to act without fear of punishment, as long as they stick to the rules. This helps encourage honest behavior and clear standards in financial and legal activities.
vertical integration financial
"as part of its strategy to vertically integrate power generation and computing infrastructure."
Vertical integration occurs when a company controls multiple stages of its production or supply chain, such as making its own products and also distributing or selling them. This can help the company reduce costs and increase control over quality and delivery. For investors, it often signals a company’s effort to become more self-sufficient and competitive in its industry.
high-performance computing technical
"to support high-performance computing applications, including Bitcoin mining and AI."
A cluster of very powerful computers, special chips and fast networks designed to tackle huge, complex calculations far faster than a normal PC — like replacing a single delivery van with a synchronized fleet to move a city’s worth of packages. For investors, high-performance computing matters because it enables faster product development, more accurate simulations and data analysis, and new revenue streams for hardware, software and services, making firms that supply or use it potentially more competitive and scalable.

Soluna and Sazmining Announce 3 MW Bitcoin Mining Operation at Project Dorothy 1B

 

Marks Sazmining’s second U.S. deployment, with potential to scale subject to customer demand and capacity availability

 

ALBANY, NY, April 28, 2026 – 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 a partnership with Sazmining, a pioneer in Bitcoin Mining as a Service (BMaaS). The collaboration will support Sazmining’s second U.S.-based mining operation with an initial 3 MW deployment at Soluna’s Project Dorothy 1B. The partnership has the potential to scale over time, subject to customer demand and facility availability.

 

“We’re excited to welcome Sazmining to Project Dorothy and support their continued U.S. expansion,” said John Belizaire, CEO of Soluna. “As Project Dorothy evolves to support both Bitcoin mining and AI workloads, partnerships like this highlight our ability to convert stranded renewable energy into high-performance computing across multiple use cases.”

 

Project Dorothy, located in West Texas, is powered by the 150 MW Briscoe Wind Farm, which Soluna recently acquired as part of its strategy to vertically integrate power generation and computing infrastructure. With full ownership of the energy source, the company is advancing development across the broader Dorothy campus, including a planned third phase that the Company expects could deliver up to 300 MW of compute capacity for AI workloads.

 

“This is exactly the kind of partnership that proves Bitcoin mining is a net positive for energy grids,” said Kent Halliburton, CEO and Co-Founder of Sazmining. “We’re not just showing up in Texas and plugging in; we’re maximizing the value of a carbon-free energy asset. That unique alignment between Bitcoin miners and energy producers is what this industry should look like moving forward.”
