Soluna Holdings, Inc. (NASDAQ:SLNH) Reports Q2 2026 Results; Revenue Grows 145% Year-Over-Year

"This is Soluna's fifth consecutive quarter of sequential revenue growth, and a 145% year-over-year increase that reflects the operating leverage we are building across the portfolio," said John Belizaire, CEO of Soluna Holdings. "Kati 1 delivered its first positive gross profit, and Dorothy 1A had its strongest quarter to date. That operating base is the foundation for the much larger AI build-out now taking shape across our pipeline. And with Ryan Carver joining as Chief Development Officer, we've added hyperscale AI delivery experience to lead that build."

"This quarter, we expanded our development pipeline to approximately 6.3 gigawatts, with major capacity growth across our AI sites," Belizaire continued. "The Dorothy 3 campus grew to 300 megawatts, and our joint venture with Metrobloks gives Kati 2 a defined path from an initial 100 megawatts of critical IT capacity toward 350 megawatts. We also dedicated three additional development sites to AI capacity, with Projects Hedy, Ellen, and Fei advancing through power term sheets to a combined 583 megawatts of behind-the-meter power aimed at AI and HPC workloads. With Briscoe and full ownership of Dorothy 1 in hand, we control the generation-to-compute chain at our flagship campus, and we are moving quickly to convert existing sites to AI and advance Dorothy 3."

Recent Operational and Corporate Highlights:

Completed Vertical Integration at Project Dorothy - Consolidated ownership of Project Dorothy 1:
- Acquired 150 MW Briscoe Wind Farm on April 1 for a $53.0 million base price.
- Acquired Spring Lane Capital's 85.4% Class B interest in Dorothy 1A on April 15 for $16.5 million.
- Acquired Navitas' 49% interest in Dorothy 1B on May 19 for approximately $8.8 million.
- Soluna now owns both the generation and the compute across all 50 MW of Project Dorothy 1.
Signed Kati 2 AI Joint Venture with Metrobloks - On June 3, 2026, Soluna entered into a joint venture agreement with Metrobloks to develop Project Kati 2. Phase I is a 100 MW critical IT data center development, with Phase II adding a further 250 MW. Soluna holds all Class A interests and serves as manager of the joint venture.
Project Kati 1 Reached 48 MW, and Delivered First Gross Profit - Kati 1 completed 48 MW of construction on April 1, filled by Galaxy Digital. Site revenue grew 938% sequentially to $2.3 million¹ and the site delivered its first positive gross profit of $82 thousand.
Project Dorothy 1A Delivered Its Strongest Quarter — Dorothy 1A revenue grew 31% sequentially to $2.9 million on the Blockware and Canaan fleet ramps, producing $795 thousand of gross profit at a 28% gross margin - the highest of any site in the portfolio.
Development Pipeline of ~6.3 GW — As of August 1, 2026, Soluna operated approximately 192 MW across three fully energized sites, with an additional 14 MW under construction at Project Kati 1. Beyond operating and construction-stage capacity, the Company's development pipeline includes approximately 1.6 GW in planning and development, with PPA negotiations, ERCOT planning, AI feasibility, and land acquisition underway, and approximately 4.5 GW in assessment with power partners.
Major Expansions of Development Project Capacity and Transition to AI — During the quarter, Soluna's development pipeline expanded across several sites. New term sheets increased, and Soluna redesignated power for AI workloads at Project Rosa (187 MW to 242 MW), Project Hedy (120 MW to 198 MW), Project Ellen (100 MW to 145 MW), and Project Fei (120 MW to 240 MW). In addition, Soluna allocated Project Grace, its 2 MW AI/HPC technical validation effort with the Siemens PTI team, to Dorothy 3 capacity.
Added to the Russell 3000 and Russell 2000 Value indices - in the latest reconstitution, with new sell-side research coverage initiated on the company in recent weeks.
Appointed Ryan Carver as Chief Development Officer - On July 16, 2026, Soluna appointed Ryan Carver as Chief Development Officer.

Second Quarter Financial Highlights:

Effective Q2, pass-through electricity costs are presented on a gross basis in revenue and cost of revenue. This presentation change adds $4.4M to each, with no effect on gross profit, operating loss, or net loss.
Revenue grew for a fifth consecutive quarter to $15.1 million, up 60% sequentially compared to Q1 and 145% year over year (73% excluding the presentation change), driven by Dorothy 2's contributions, the Kati 1A ramp, and Briscoe's first quarter under ownership, partially offset by hashprice compression.
Gross profit was $766 thousand in Q2, compared to $1.9M in Q1, primarily impacted by $1.5M of Briscoe maintenance costs, Kati 1 ramp costs, and depreciation coming online ahead of full revenue contribution.
Net loss was ($22.6M), compared with ($17.9M) in Q1, driven primarily by a $4.2M loss on debt extinguishment and the new Briscoe overhead and depreciation base, partially offset by lower SG&A.
Adjusted EBITDA Loss of ($1.6M) improved 25% compared with ($2.1M) in Q1, driven by lower legal and consulting fees following the close of the Briscoe acquisition and lower compensation, alongside continued gross-profit contribution from Dorothy 2.
Ended the quarter with $113.4M of unrestricted cash and $33.1M of total debt. Subsequent to quarter-end, the Company raised approximately $23.6 million under its at-the-market (ATM) program, with approximately 244,590,575 shares outstanding as of the filing date of the Company's Quarterly Report on Form 10-Q.
