Soluna Holdings, Inc. (SLNH) How It Works

Soluna Holdings operates as a renewable computing company, fundamentally transforming otherwise wasted or curtailed clean energy-from wind, solar, or hydro-into high-performance computing capacity. They achieve this by co-locating modular data centers directly with renewable power plants, using their proprietary software to monetize surplus power for intensive applications like Bitcoin mining and Artificial Intelligence.

Soluna Holdings, Inc.'s Product/Service Portfolio

The company generates revenue through a diversified four-pronged model, with data center hosting being the primary income driver as of late 2025, surpassing proprietary mining. This diversification helps mitigate the volatility inherent in the cryptocurrency market.

Soluna Holdings, Inc.'s Operational Framework

Soluna's core operational strategy is built on a capital-efficient, 'power-plus-compute' model that directly addresses the problem of renewable energy curtailment (wasted energy). This is a defintely smart way to turn a liability into an asset.

• Co-location and Behind-the-Meter Setup: They strategically locate modular data centers directly next to wind, solar, or hydroelectric power plants, often 'behind-the-meter.' This setup allows them to consume energy that the main grid cannot accept, bypassing grid congestion issues and securing a lower, more stable power cost.
• Proprietary Software (MaestroOS™): Their operating system manages the power flow, dynamically directing stranded clean energy to computing tasks. This software is the brain, ensuring the data center load is flexible and responsive to the grid's needs, which enables the Demand Response revenue.
• Aggressive Capacity Expansion: The company is focused on scaling its infrastructure, evidenced by the completion of Project Dorothy 2, which increased operational capacity, and the groundbreaking of Project Kati 1 (a 35 MW phase of a 166 MW wind-powered site) in September 2025.
• Capital Structure Strengthening: Soluna secured a scalable credit facility of up to $100 million from Generate Capital in Q3 2025, with an initial draw of $12.6 million, to fund construction and refinance existing projects. This shows a clear focus on funding the project pipeline.

Soluna Holdings, Inc.'s Strategic Advantages

The company's market success is driven by its unique positioning at the intersection of clean energy and high-performance computing, giving it a distinct edge over traditional data center operators and pure-play miners.

• Lowest-Cost Power: By monetizing curtailed energy, Soluna accesses a power source that is significantly cheaper than standard grid power, translating to a competitive advantage in operating costs. This is the whole game.
• Diversified Revenue for Stability: The pivot to data center hosting, which generated 63% of Q3 2025 revenue and 87% of gross profit, provides a more reliable cash flow stream than just proprietary mining, which is subject to Bitcoin price and halving volatility.
• Massive Development Pipeline: Soluna has amassed a power pipeline exceeding 2.8 GW of AI and Bitcoin hosting capacity, including projects like Rosa, Hedy, and Ellen. This large pipeline provides clear visibility for multi-year growth and scale.
• AI/HPC Pivot: The strategic shift toward High-Performance Computing and AI-ready data centers, starting with Project Kati, positions the company to capture demand from the rapidly growing, high-margin AI compute market, moving beyond a sole reliance on Bitcoin mining.

Soluna Holdings, Inc. (SLNH) How It Makes Money

Soluna Holdings, Inc. (SLNH) makes money by transforming otherwise wasted renewable energy-like curtailed wind power-into a revenue-generating asset through its co-located data centers, primarily by providing data hosting services for cryptocurrency mining and, increasingly, high-performance computing (HPC) clients.

This model essentially creates a profitable buyer of last resort for clean power producers, monetizing energy that would otherwise be lost to curtailment (when a power plant must reduce its output below what it is capable of generating due to transmission or grid stability issues).

Soluna Holdings' Revenue Breakdown

The company's revenue mix is undergoing a significant strategic pivot, moving away from owning and operating its own cryptocurrency mining equipment (prop mining) toward a more stable, higher-margin data hosting model. This shift is clearly visible in the latest quarterly data.

In the third quarter of 2025, Soluna Holdings reported total revenue of $8.42 million, a strong 37% increase from the previous quarter, largely driven by new customer deployments at its Dorothy 2 facility in Texas. Hosting revenue, which constituted the majority at 63%, is the clear growth engine, while the company's own cryptocurrency mining operations are being de-emphasized.

Business Economics

Soluna Holdings' economic fundamentals are rooted in the arbitrage of stranded clean energy and the high demand for compute power. They are a 'Renewable Computing' pioneer, which means they build modular data centers right next to renewable energy sites, like wind farms, to capture the cheapest electricity available.

• Low Power Cost: The core advantage is securing power purchase agreements (PPAs) for energy that would otherwise be curtailed, resulting in a best-in-class power cost for their computing operations. This is a defintely critical factor in the post-halving Bitcoin mining environment.
• Hosting Margin Expansion: The shift to a Data Hosting model means Soluna Holdings earns a recurring fee for providing power and infrastructure to third-party miners, insulating them from direct Bitcoin price volatility. This is a much more predictable revenue stream.
• Proprietary Optimization: They use a platform called MaestroOS to manage and optimize the power draw of their data centers, allowing them to instantly curtail computing load when the grid needs the power, which is how they generate Demand Response Services revenue.
• Diversification into AI/HPC: The company is actively pivoting its development pipeline to serve High-Performance Computing (HPC) clients, particularly in the Artificial Intelligence (AI) space, which offers even higher margins and a more stable, enterprise-level customer base than cryptocurrency mining. Project Kati 1, a 35 MW wind-powered site in Texas, is a key part of this expansion.

Soluna Holdings' Financial Performance

As of the end of Q3 2025, the financial performance shows a company in transition, successfully executing a strategy shift but still managing significant non-cash items that impact the bottom line.

• Gross Margin Improvement: The gross profit margin improved substantially to 28% in Q3 2025, up from 19% in the prior quarter. This increase reflects strong cost discipline and the positive impact of the transition to the higher-margin hosting model.
• Adjusted EBITDA: Core business health is best seen in the adjusted figures; while the reported Adjusted EBITDA was a loss of $(6.37) million for the quarter, the figure excluding special charges (like certain compensation and financing fees) was near break-even at a positive $0.1 million. This shows the operational business is stabilizing.
• Net Loss and Non-Cash Charges: The reported GAAP net loss for Q3 2025 was a significant $(25.79) million. However, this was primarily driven by a large, non-cash $22.0 million fair value adjustment related to exercised warrants from a July equity offering, not core operational issues.
• Balance Sheet Strength: The company significantly bolstered its liquidity, increasing cash reserves by $45 million to a record $60.5 million as of September 30, 2025, following a successful capital raise of over $64 million gross. This capital is crucial for funding their extensive project pipeline, which exceeds 1 gigawatt in operation, construction, and development.
