Insights

Financial Analyst

Soluna's 2024 results demonstrate solid financial momentum with 80.5% revenue growth to $38 million, driven by the first full year of Project Dorothy 1A/1B operations. The company's core Bitcoin mining and hosting businesses performed well despite the Bitcoin halving event in April 2024.

Most encouraging is the company's turnaround in Adjusted EBITDA, which improved to $0.9 million from a $3.5 million loss in 2023. This represents the first positive cash flow from core operations—a critical inflection point. Unrestricted cash increased 23.2% year-over-year to $7.8 million, strengthening Soluna's balance sheet.

The decision to terminate the HPE GPU-as-a-Service contract, while resulting in a substantial $28.6 million loss, appears to be a strategic move to eliminate a drag on performance amid softening GPU-as-a-Service market conditions. This decisive action to cut losses demonstrates management's willingness to make tough decisions to preserve long-term value.

Soluna's capital structure improvements—reducing Convertible Loan Notes to zero and restructuring Series B Preferred Stock—position the company more favorably for raising growth capital. The $25 million Standby Equity Purchase Agreement provides additional financial flexibility to fund expansion projects.

The gross profit metrics reveal a tale of two businesses: the core Bitcoin operations delivered $15.1 million in gross profit (excluding Project Ada/Cloud losses of $5.7 million), demonstrating the viability of the company's primary business model when properly executed. Q4 showed particular strength with gross profit margins in the Digital segment improving to 31.0% from 19.9% in Q3.

Energy Infrastructure Specialist

Soluna's integrated energy strategy is gaining traction with substantial capacity expansion underway. Project Dorothy 2 will increase Bitcoin hosting capacity by 64.0% to 123 MW, positioning the company to capture additional market share in the sustainable Bitcoin infrastructure space.

The company's diversified revenue streams show promising development. While Bitcoin hosting and mining form the core business, the addition of Demand Response Services (DRS) generated $2.1 million in its first full year of operation. This represents a strategic enhancement to Soluna's business model, allowing the company to monetize its power management capabilities during peak grid demand periods.

Soluna's project pipeline expansion is particularly noteworthy. Project Kati has successfully exited the ERCOT planning phase, potentially unlocking 166 MW of capacity for Bitcoin hosting and AI applications. Similarly, Project Rosa's power term sheets and land agreement could add another 187 MW of capacity. This combined 353 MW pipeline represents nearly triple the company's current capacity.

The strategic pivot away from small-cluster GPU-as-a-Service is sensible given market conditions. By refocusing on large-scale Bitcoin infrastructure and AI data centers built at their renewable energy projects, Soluna is playing to its strengths in power-intensive computing applications where energy efficiency and sustainable sourcing create competitive advantages.

The company raised over $31.5 million in capital for its data center projects, demonstrating investor confidence in Soluna's renewable energy computing model. This capital influx supports the company's expansion strategy while validating their approach of co-locating computing infrastructure with renewable energy sources to transform surplus power into valuable computing resources.

Project pipeline growth, cash growth, and capital structure simplification highlight the focus and execution in core business.

ALBANY, N.Y.--(BUSINESS WIRE)-- Soluna Holdings, Inc. (“Soluna Holdings” or the “Company”), (NASDAQ: SLNH), a developer of green data centers for intensive computing applications including Bitcoin mining and AI, announced financial results for the full year ended December 31, 2024.

Soluna Holdings, Inc., Cumulative Revenue by Quarter (2024)

“Our 2024 results reflect continued momentum and strong execution across our core businesses of Bitcoin hosting, mining, and demand response services,” said John Belizaire, CEO of Soluna Holdings.

“We broke ground on Project Dorothy 2, which will increase our Bitcoin Hosting capacity to 123 MW when fully ramped. We significantly expanded our project pipeline and launched our AI/HPC business to meet the growing demand for sustainable AI compute. These milestones mark a pivotal phase of growth and validate our long-term strategy to lead the next wave of clean, efficient infrastructure for Bitcoin Hosting and AI,” continued John Belizaire.

“We terminated our HPE GPU-as-a-Service contract to mitigate losses seen in the second half of 2024 and enable us to focus on the growth of our substantial pipeline of projects into AI/HPC data centers during 2025, beginning with Project Kati,” said John Tunison, CFO of Soluna Holdings.

“Additionally, we have made substantial progress towards simplifying our capital structure, including reducing our Convertible Loan Notes to zero and securing modifications to the terms of our Series B Preferred Stock, which we believe strengthens our ability to raise the growth capital needed to execute on our strategic plan and has resulted in positive cash flow from our core business for the first time,” continued John Tunison.

2024 Operational and Corporate Highlights:

• Record revenue grew by 80.5%, reaching $38.0 million, compared to $21.1 million in 2023.
• Our sites operated at a high operational efficiency and produced strong financial results despite the “halving” of Bitcoin in April 2024.
• Project Dorothy 1A and 1B were online for the full year of 2024, generating $13.7 million and $17.0 million in Bitcoin hosting and mining revenue, respectively.
• Demand Response Services (“DRS”) commenced in December 2023 and generated $2.1 million in revenue in 2024, following substantial development and preparation over the prior year.
• Total revenue grew by 9.9% to $8.3 million in Q4 2024 compared to Q3 2024, driven by higher hash price and change in customers with higher profitability.
• Capital raised at Soluna Holdings and at the Data Center Projects exceeded $31.5 million - $2.3 million in warrant exercises and $29.2 million between Soluna AL CloudCo, LLC (“CloudCo” or “Project Ada”), a wholly owned subsidiary of Soluna Cloud, Inc. (“Cloud”), and Project Dorothy 2 in the form of debt and equity, respectively.
• Soluna Digital achieved a quarterly gross profit of $2.6 million, or 31.0%, in Q4 2024 compared to $1.5 million, or 19.9%, in Q3 2024.
• Current & Restricted Cash maintained at $10.5 million at the end of 2024, while unrestricted cash grew by 23.2% to $7.8 million from the end of 2023.
• We simplified our capital structure by fully converting Convertible Loan Notes and significantly restructuring the Preferred B equity.
• Construction of Project Dorothy 2 started in the third quarter of 2024, and the initial phase of powering up is underway, which aims to increase our Bitcoin hosting capacity by 64.0%, reaching a total of 123 MW, which is expected to be fully completed by Q4 2025.
• Project Kati successfully exited the ERCOT planning phase, which is expected to unlock up to 166 MW of new Bitcoin hosting and AI joint venture opportunities for the Company.
• Term Sheets for Power for Project Rosa in 2024 and a land agreement were subsequently secured in early 2025, which is expected to unlock up to 187 MW of new Bitcoin hosting and AI joint venture opportunities for Soluna Holdings.

“I am honored to lead this team,” John Belizaire continued. “Their dedication and grit have been the driving force behind our continued momentum and success.”

• Growth Capital Secured by entering into the Standby Equity Purchase Agreement (SEPA) - In Q4 2024, the Company filed a registration statement for the resale of the shares of common stock in connection with the $25 million SEPA entered into with Yorkville Advisors Global L.P. in August 2024. In early 2025, the registration statement was declared effective by the SEC, enabling us to raise capital to pay debt, invest in data center projects, and for working capital and general corporate purposes.
• CloudCo completed a strategic termination of the Hewlett Packard Enterprise Company (“HPE”) contract - Recognizing the 2024 downtrend in market pricing and softening demand for GPU-as-a-Service in small clusters, in March 2025, the Company’s indirect subsidiary, CloudCo terminated the HPE contract to access Nvidia GPUs and recorded a loss on contract of $28.6 million which is the sum of future payments due under the contract and the full write down of the prepaid asset. The strategic termination of the contract enables us to refocus on Bitcoin and the future development of AI data centers at our Projects. Following CloudCo’s termination, HPE terminated the contract for cause, effective immediately.

• Selling, General & administrative expenses grew by $3.3 million for the year ended December 31, 2024, as expected, through expanded hiring of key talent, consulting, and compliance costs - driven by company growth and progressing the company's strategy.
• Salary and wages increased by approximately $0.6 million during the year ended December 31, 2024 due to an increase in resources and salaries.
