Soluna Holdings, Inc. (SLNH) is a pioneering digital infrastructure company that is transforming the intersection of renewable energy and high-performance computing. With a mission to make renewable energy a global superpower, Soluna is leveraging its expertise in modular data centers to create cost-effective and environmentally friendly computing solutions for a wide range of applications, from Bitcoin mining to Artificial Intelligence (AI) workloads.

Business Overview and History

Soluna was originally incorporated in 1961 as Mechanical Technology, Incorporated, and later reincorporated in Nevada in 2021, changing its name to Soluna Holdings, Inc. The company's journey truly began in 2021 when it acquired Soluna Computing, Inc. (SCI), a private green data center development company. This strategic move allowed Soluna to expand its focus towards the convergence of renewable energy and computing, a vision that has since defined the company's growth trajectory.

In the same year, Soluna commenced mining operations at its Murray, Kentucky location Project Sophie and Calvert City, Kentucky site Project Marie. The company also completed the Soluna Callisto acquisition, which provided the opportunity to directly employ or retain the services of four individuals whose services it had previously retained through Harmattan Energy, Ltd. This acquisition involved various transactions with Harmattan Energy, Ltd., negotiated on behalf of the company via an independent investment committee of the Board and separate legal representation.

Soluna's business model has evolved to encompass three distinct revenue streams: Cryptocurrency Mining, Data Center Hosting, and High-Performance Computing (HPC) Services. However, the company faced significant challenges in 2022 and 2023. A sharp drop in Bitcoin prices, compounded by geopolitical tensions and surging global energy costs, led to market destabilization and industry setbacks. In February 2023, Soluna's asset-backed-lender NYDIG accelerated their loan and repossessed their collateralized assets, resulting in the decommissioning of Project Marie.

Despite these challenges, Soluna has made progress in diversifying its operations. The company transitioned Project Sophie from proprietary mining to hosting services in the second quarter of 2023 and began participating in demand response programs to generate additional revenue. In September 2022, Soluna divested specific mining assets at its Wenatchee, Washington facility Project Edith while continuing to manage operational contracts for the new owner. The company later divested the legal entity and ceased management of operational contracts for Project Edith in August 2024.

Soluna has also focused on improving operational efficiency and profitability across its existing projects through cost-cutting initiatives and the implementation of a new Financial Planning and Analysis function. These efforts, combined with the company's strategic diversification, demonstrate Soluna's ability to adapt to the dynamic landscape of the technology and energy sectors.

Business Segments

Soluna Holdings, Inc. operates in three primary business segments: Cryptocurrency Mining, Data Center Hosting, and High-Performance Computing Services.

1. Cryptocurrency Mining Segment: This segment generates revenue from the cryptocurrency Soluna earns through its mining activities. Currently, the focus is on Project Dorothy, a 25 MW data center located in Silverton, Texas that began energization in the third quarter of 2023. For the three months ended September 30, 2024, 100% of the company's cryptocurrency mining revenue was generated from Project Dorothy 1B. Over the nine months ended September 30, 2024, Project Dorothy 1B accounted for 100% of the company's cryptocurrency mining revenue. The increase in cryptocurrency mining revenue from the prior year was primarily due to Project Dorothy 1B being fully operational throughout 2024, whereas it was still ramping up during the third quarter of 2023. Additionally, the average price of Bitcoin increased by 118% from the three months ended September 30, 2023 to the same period in 2024, and by 128% for the nine-month comparison, further contributing to the year-over-year growth in cryptocurrency mining revenue.

2. Data Center Hosting Segment: This segment generates revenue from contracts for the provision and operation of data center services for customers engaged in cryptocurrency mining. This includes fees for hosting third-party mining hardware as well as potential additional service fees. Data hosting revenue was $4.27 million for the three months ended September 30, 2024, up 6% from $4.01 million in the prior year period. The increase was primarily driven by the continued energization and deployment of hosting customers at Project Dorothy 1A, which began operations in the second quarter of 2023. Project Dorothy 1A accounted for 82% of data hosting revenue in Q3 2024, compared to 75% in the prior year quarter. Over the nine months ended September 30, 2024, data hosting revenue was $14.45 million, up 165% from $5.45 million in the same period of 2023, largely due to the ramp-up of hosting operations at both Project Dorothy 1A and Project Sophie.

3. High-Performance Computing Services Segment: This segment was newly launched in 2024. It provides GPU-as-a-Service and colocation services at Soluna's data centers to support companies' artificial intelligence and other high-performance computing workloads. For the three and nine months ended September 30, 2024, this segment did not generate any revenue, as the company's new Project Ada facility was still in the process of building its customer base. However, the company did incur $2.86 million in costs related to the HPE agreement to acquire datacenter and cloud services for AI and HPC processes.

Financial Performance and Ratios

Soluna's financial performance has been marked by significant strides in recent years, despite the challenges faced by the broader technology and cryptocurrency industries. The company's revenue has grown from $14.35 million in 2021 to $28.55 million in 2022, representing a year-over-year increase of approximately 99%. This impressive growth has been driven by the company's ability to successfully execute its diversification strategy and capitalize on the growing demand for sustainable computing solutions.

For the fiscal year 2023, Soluna reported revenue of $29.75 million, net income of -$27.70 million, operating cash flow of -$2.99 million, and free cash flow of -$12.71 million. In the most recent quarter (Q3 2024), the company's revenue reached $7.53 million, representing a 29.8% year-over-year growth. However, the company continued to incur a net loss of $8.09 million in Q3 2024.

The company's profitability, as measured by net income, has been impacted by various non-recurring charges and impairment expenses related to the optimization of its asset portfolio. In 2022, Soluna reported a net loss of $98.72 million, which included a $63.34 million charge for unusual items. However, the company's Adjusted EBITDA, a key metric that excludes the impact of these one-time items, has shown a more positive trajectory, improving from a loss of $593,000 in 2021 to a loss of $8.23 million in 2022.

Liquidity

Soluna's liquidity position remains a point of focus. As of September 30, 2024, the company's debt-to-equity ratio stood at 0.50x, indicating a moderate level of leverage. The company's cash balance was $8.77 million, with a current ratio of 0.59x and a quick ratio of 0.59x. Soluna has a $1 million unsecured line of credit with KeyBank, which was fully paid down as of September 30, 2024. The company does not currently plan to draw on this facility.
