Exhibit 99.1

Soluna

Acquires Full Ownership of Project Dorothy 1A, Accelerating Vertical Integration and AI Campus Development

$16.5M

acquisition consolidates Dorothy campus control; positions Soluna to convert existing infrastructure to AI and market Dorothy 3 to prospective

customers

ALBANY,

NY, April 16, 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 the acquisition of Spring Lane Capital’s equity interest in Project

Dorothy 1A (“D1A”) for $16.5 million. The transaction gives Soluna complete equity ownership of D1A, located in

Silverton, Texas, and marks the second major step in the Company’s vertical integration of the Dorothy campus, following the $53

million acquisition of the Briscoe Wind Farm earlier this month.

With

full ownership of D1A and Briscoe providing 150 megawatts of owned renewable power, Soluna is positioning itself to convert the Dorothy

campus to AI computing as Dorothy 3 development advances and opens the door to bringing new equity partners onto the site on terms

aligned with the Company’s AI-first strategy.

The

acquisition represents a natural conclusion to Soluna’s partnership with Spring Lane Capital on the D1A project. SpringLane’s

Fund I receives cash liquidity for its ownership interest, while Soluna gains the full equity control necessary to change the business

plan of its Dorothy projects to support AI workloads and accelerate the development of Dorothy 3.

“Spring

Lane Capital was the right partner for the first chapter of Dorothy,” said John Belizaire, CEO of Soluna. “With Briscoe secured

and Dorothy 1A now fully owned, we have the foundation for what comes next: a vertically integrated AI campus, from energy generation

to compute infrastructure, that we control end to end. That control is what gives us an accelerated path to power for AI customers.”

Transaction

Details

The

$16.5 million acquisition will be paid in cash in two installments: $6 million at closing, with the balance due in July 2026. Soluna

previously held 14.6% interest in the Class B Membership Interests of D1A; this acquisition of the remaining 85.4% brings Soluna’s

ownership of D1A to 100%, as it already owns 100% of the Class A Membership Interests. To finance a portion of the transaction, Soluna

signed an unsecured promissory note with a lender in the principal amount of $12 million, maturing on

May 15, 2027, which closed concurrently with the acquisition. Additional details regarding the

transaction and the promissory note will be described in the Company’s Current Report on Form 8-K to be filed with the Securities

and Exchange Commission (“SEC”).

Path

to Full Campus Ownership

Soluna

intends to pursue full ownership of the entire Project Dorothy campus. Discussions regarding Dorothy 1B and Dorothy 2 are underway. For

Dorothy 3, the Company’s plan is to obtain significant ownership with the option to bring in new equity partners aligned with the

AI infrastructure buildout. In the medium term, as Dorothy 3 development matures, the campus will transition to AI as its primary workload.

Soluna expects to provide updates on campus ownership consolidation and Dorothy 3 development in its regular SEC filings and investor

communications.

The

D1A acquisition follows a series of strategic actions in 2026, including the Briscoe Wind Farm acquisition, the achievement of substantial

completion at Kati 1 ahead of schedule, and the advancement of AI-focused development at Kati 2 and Grace. Soluna’s development

pipeline now exceeds 4.3 gigawatts across multiple sites.
