**Glossary of Abbreviations and Acronyms for Selected References**

The following list defines various abbreviations and acronyms used throughout this Annual Report on Form 10-K (this "Annual Report"), including the Business Section, the Management's Discussion and Analysis of Financial Condition and Results of Operations, the Consolidated Financial Statements, the Notes to Consolidated Financial Statements and the Financial Statement Schedules.

This glossary covers essential terms related to Bitcoin mining, high-performance computing, Artificial Intelligence and related fields, providing valuable context for readers of this Annual Report. A number of cross-references to additional information included throughout this Annual Report are also utilized throughout this Annual Report, to assist readers seeking additional information related to a particular subject.

**Artificial Intelligence ("AI")**: The simulation of human intelligence processes by machines, especially computer systems. These processes include learning (the acquisition of information and rules for using the information), reasoning (using rules to reach approximate or definite conclusions), and self-correction. AI applications include expert systems, natural language processing, speech recognition, and machine vision.

**Bitcoin**: A decentralized digital currency created in 2009 by an unknown person or group of people using the name Satoshi Nakamoto. It operates on a peer-to-peer network, allowing direct transactions without intermediaries. Transactions are verified by network nodes through cryptography and recorded on a publicly distributed ledger called a blockchain.

**Bitcoin Halving**: An event occurring approximately every four years where the reward for mining new Bitcoin blocks is halved. This reduces the number of new Bitcoins generated by miners, impacting their profitability and potentially affecting Bitcoin's value. Bitcoin Halving is part of Bitcoin's deflationary monetary policy, designed to control supply.

**Bitcoin Mining**: The process of adding new transactions to the Bitcoin blockchain. It involves solving complex cryptographic puzzles to discover a new block, rewarding miners with transaction fees and newly created Bitcoins. This process secures and verifies transactions on the network.

**Curtailment ("Curtailed" or "Curtailments"):** In energy management, the reduction in electrical power supply by power plants to balance the grid or avoid excess generation. In Bitcoin mining or other computing activities, curtailment - pausing computing activities and related energy usage - can occur during peak demand periods or insufficient energy supply.

**Data Center Colocation**: A service where businesses can be provided with services and infrastructure such as electrical power and network connectivity for servers and other computing hardware at a third-party provider's data center. This arrangement allows for cost savings, better infrastructure, and enhanced security compared to private data centers.

**Electric Reliability Council of Texas ("ERCOT"):** An independent system operator that manages the flow of electric power to more than 26 million Texas customers, representing about 90 percent of the state's electric load. ERCOT schedules power on an electric grid that connects more than 46,500 miles of transmission lines and over 680 generation units.

**Exahash ("EH/s")**: A unit of computational power equal to one quintillion (10^18) hashes per second. EH/s are used to measure the hashrate of the most powerful cryptocurrency mining equipment and the overall computational power of the Bitcoin network.

**Fork**: A fork refers to a change or divergence in the protocol of a blockchain network. It occurs when the blockchain's code is modified, resulting in two separate chains: one that follows the old rules and one that follows the new rules.

**Generative AI**: AI that can generate new content, such as text, images, or music, based on its training data. It learns from vast amounts of data to create outputs that mimic original human-generated content, often used in creative and analytical applications.

**Gigawatt ("GW")**: A unit of power equal to one billion watts. Often used to measure the capacity of large power plants or the power usage of large operations like data centers and industrial complexes.

**Graphics Processing Unit ("GPU")- as-a Service**: The sale of GPU clusters, ranging from bare metal to turnkey solutions, which may be either owned by the Company, or leased from another company and that are housed within data

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

centers which may be owned by the Company or leased from another company, typically on a "per GPU-hour" basis, either on a reserved or on demand basis.

**Grid Demand Response Services**: Services provided to support the basic services of generating and delivering electricity to the grid. They help maintain power quality, reliability, and efficiency. In the context of Bitcoin mining, the use of mining facilities to provide grid stabilization services is an emerging concept.

**Hashrate**: The measure of computational power per second used in cryptocurrency mining. It indicates the number of hash function computations per second by a miner's hardware, with higher hashrates implying greater efficiency and network security.

**High Performance Computing ("HPC")**: The use of supercomputers and parallel processing techniques for solving complex computational problems. HPC is used in fields such as scientific research, simulation, and large-scale data analysis.

**Joules**: A unit of energy in the International System of Units (SI). One joule is the energy transferred when one watt of power is exerted for one second. In Bitcoin mining, energy efficiency is often measured in joules per hash.

**Large Language Models ("LLMs")**: Advanced AI models designed to understand, generate, and respond to human language in a way that mimics human-like understanding. They are trained on vast datasets and can perform a variety of language-based tasks, such as translation, summarization, and question-answering.

**Machine Learning**: A subset of AI involving the creation of algorithms that can learn and make decisions or predictions based on data. It enables computers to improve their performance on a specific task with experience and data, without being explicitly programmed.

**Megawatts ("MW")**: A unit of power measurement equivalent to one million watts. Used to measure the electrical power consumption of large operations like data centers and Bitcoin mining rigs.

**Mining Pool**: A group of cryptocurrency miners who combine their computational resources over a network to increase their chances of finding a block and receiving rewards. The rewards are then divided among the pool participants, proportional to the amount of hashing power each contributed.

**NYDIG ABL LLC ("NYDIG")**

**Petahash ("PH/s")**: A unit of computational power equal to one quadrillion (10^15) hashes per second. It is used to measure the hashrate of extremely powerful cryptocurrency mining equipment.

**Power Usage Effectiveness ("PUE")**: A ratio that describes how efficiently a computer data center uses energy; specifically, how much energy is used by the computing equipment (in contrast to cooling and other overhead that supports the equipment).

**Overview**

Our mission is to make renewable energy a global superpower by using computing as a catalyst.

We develop, own, and operate digital infrastructure for energy-intensive computing applications by colocating data centers with renewable energy power plants. We refer to this model as Renewable Computing™.

Renewable Computing™ is designed to address two converging market conditions: increasing curtailment of renewable energy generation and growing demand for power-intensive computing applications, including artificial intelligence ("AI"), high-performance computing ("HPC"), and Bitcoin mining. By locating our data centers near renewable generation assets, we seek to convert underutilized energy into economically productive computing capacity.

We utilize two distinct data center designs to serve different computing markets. For our Bitcoin mining and hosting business, we deploy a modular data center design optimized for flexible, large-scale digital asset operations. For AI and HPC workloads, we are developing an AI-ready data center design intended to support higher-density compute environments and customer requirements associated with advanced computing infrastructure.

Our facilities are managed by MaestroOS™ ("MaestroOS"), our proprietary software platform, which analyzes factors such as local power pricing, weather conditions, grid demand, and market signals to optimize operating performance and power consumption across our operating assets.

Our business model is intended to enhance the monetization of renewable generation assets while supporting scalable digital infrastructure growth. We work with renewable energy developers and power partners to access low-cost or otherwise constrained energy resources. Our data centers operate on a behind-the-meter basis, enabling them to draw electricity directly from the co-located renewable power plant and from the grid through the plant's existing interconnection and substation infrastructure. By accessing both sources of power, our facilities are able to meet their energy needs while maintaining operating flexibility. In certain markets, our facilities also participate in demand response programs that support grid reliability.

A key element of our strategy is the colocation of data centers directly with renewable generation assets. By building behind the meter at renewable generation sites, we are able to access both on-site generation and existing grid interconnection infrastructure, which we believe can improve power economics and accelerate development timelines.

With a repeatable development approach and an expanding pipeline of projects, we are seeking to scale a differentiated digital infrastructure platform that supports renewable power utilization, flexible computing capacity, and long-term value creation.

***Lines of Business***

*Bitcoin Hosting Business*

*We* provide colocation and hosting services to third-party Bitcoin mining customers at our data centers. Customers typically contract for capacity based on their power requirements. Our customer base includes several large-scale Bitcoin mining operators. Contracts generally range from 12 to 24 months in duration.

We offer three primary commercial structures:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fixed-Fee Model – Customers pay a fixed fee based on energy consumed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Profit-Share Model – Customers pay a share of the profits from their mining activity, with power costs generally passed through.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fixed-Fee Service Agreement Model – Customers pay a fixed fee for managed Bitcoin mining capacity and hashrate over the term of the service agreement.

In 2025 and 2024, our Bitcoin Hosting Business accounted for approximately 57% and 50% of total revenue, respectively. Revenue in this business has been concentrated among a limited number of customers. In 2025, two customers accounted for 59% of hosting revenue and 34% of total revenue. In 2024, one customer accounted for 56% of hosting revenue and 28% of total revenue. That customer terminated its agreement during the fourth quarter of 2024. As of March 2025, we had replaced 100% of the lost hosting capacity with minimal operational disruption.

*Bitcoin Mining Business*

We engage in proprietary Bitcoin mining, a process that validates transactions and secures the Bitcoin blockchain. This process uses specialized computing equipment to solve complex cryptographic algorithms. Miners compete to solve these algorithms, and the first to do so is awarded a predetermined number of newly issued Bitcoins (the "Block Reward"), together with the transaction fees associated with that block.

We participate in one or more mining pools, which are collaborative networks of miners that combine computing power to improve the probability of earning rewards. Block Rewards earned by the pool are distributed among participants based on each participant's proportional contribution. We believe this model reduces revenue volatility as compared to operating on a solo mining basis.

Mining operations are energy-intensive and require significant computational resources. We operate data centers using both proprietary and third-party hardware and software. MaestroOS is used to optimize performance, manage power consumption, and improve operating efficiency.

Revenue from Bitcoin mining consists of Block Rewards and transaction fees and is recognized upon receipt in accordance with applicable accounting guidance. Upon receipt, digital assets are promptly converted into U.S. dollars through the Coinbase cryptocurrency exchange.

Mining profitability is affected by several factors, including the market price of Bitcoin, global network hash rate, mining difficulty, electricity and infrastructure costs, and mining pool fees. In addition, Bitcoin undergoes a periodic halving event, approximately every four years, that reduces the Block Reward and may adversely affect future revenue. For the years ended December 31, 2025 and 2024, our Bitcoin Mining Business represented approximately 38% and 45% of total revenue, respectively.

*High Performance Computing Business*

Our HPC business is being developed through Soluna HPC, Inc. and is focused on data center leasing and hosting solutions for AI and other HPC workloads, with an initial target customer base of Hyperscalers and Neoclouds, and enterprise customers over time.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

Unlike our Bitcoin mining and hosting operations, which use a modular data center design, our HPC business is based on an AI-ready data center design intended to support higher-density compute environments and the infrastructure requirements of AI and HPC customers.

We are currently advancing infrastructure projects intended to support AI and HPC workloads. These activities include site and feasibility studies, power and land procurement, engineering and design work, customer engagement, and evaluation of potential financing and partnership structures.

Our first planned large-scale HPC development is Project Kati 2, which is being engineered for more than 300 MW of capacity in partnership with Metrobloks. We expect Project Kati 2 to serve as the initial platform for Soluna HPC, Inc.'s leasing and hosting business. We are also advancing additional projects from our development pipeline that are in various stages of evaluation, engineering, and development.

In March 2025, we terminated our prior agreement with Hewlett Packard Enterprise Company ("HPE"), which had supported our earlier GPU-as-a-Service offering. Following that termination, we refocused our HPC strategy on the development of dedicated data center infrastructure for third-party leasing and hosting.

*Demand Response Business*

We provide demand response services to grid operators and utilities by using our data centers as dispatchable energy resources. In certain markets in which we operate, our data centers participate in ancillary services and other demand response programs that support grid reliability.

Under these programs, we commit to reduce a facility's power consumption to a predetermined level when called upon by the grid operator. In return, we receive compensation for maintaining this dispatch capability, provided we satisfy applicable performance requirements. These requirements typically include minimum uptime and availability thresholds during a measurement period, which is often monthly.

For the years ended December 31, 2025 and 2024, our Demand Response Business represented approximately 4% and 6% of total revenue, respectively.

***Operations and Project Pipeline***

As of December 31, 2025, we operate approximately 123 MW of capacity across two active sites located in Murray, Kentucky and Silverton, Texas. An additional 83 MW is under construction and 100+ MW is in development at our Kati project site, and as of December 31, 2025, we had over 900 MW of facilities in advanced development or near shovel-ready status. In total, our project pipeline includes approximately 4.3 gigawatts (GW) of renewable energy-powered data center developments.

We manage our data center operations using **MaestroOS.** MaestroOS continuously monitors and analyzes a variety of real-time signals, including local electricity prices, weather conditions, Bitcoin market metrics, and grid demand signals, to optimize facility performance. In addition, MaestroOS is used to coordinate and execute our participation in demand response programs.

We finance the development and construction of our data centers through a combination of public equity offerings, debt instruments, and partnerships with project-level capital providers. As of December 31, 2025, we had four primary project-level financing partners:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Spring Lane Capital ("SLC")** – a private venture capital firm with approximately $450 million in assets under management, focused on sustainability-oriented infrastructure. On May 3, 2022, SLC committed $35 million to finance Soluna's Project Dorothy 1A ("D1A"). On July 22, 2024, SLC committed an additional $30 million to support the development of D2. On July 22, 2025, SLC committed $20.0 million for the first phase of the construction on Project Kati, subject to customary conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Navitas West Texas Investments SPV, LLC ("Navitas")** – an investment vehicle organized by Navitas Global, a private equity firm focused on sustainable Bitcoin mining. On May 9, 2023, we entered into a strategic partnership with Navitas to support mining operations at Project Dorothy 1B ("D1B").

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Galaxy Digital, LLC ("Galaxy")** – a financial services and investment management innovator in the digital asset and blockchain technology sectors. On March 12, 2025, Soluna SW LLC (the "SW Borrower"), a Delaware limited liability company and subsidiary of Soluna SW Holdings LLC ("SW Holdings", and together with the SW Borrower, the "SW Loan Parties"), entered into a five-year term loan facility in the principal amount of $5.0 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Generate Capital ("Generate")** – a leading infrastructure investment firm. On September 12, 2025, we entered into an up to $100.0 million credit facility with Generate, and as of December 31, 2025, we had drawn approximately $17.0 million to fund refinancing and construction of active data center projects.

**Project Dorothy**

During 2023, we transitioned our flagship data center Project Dorothy from construction to operations. This data center is co-located with Briscoe Wind Farm ("Briscoe"), a 150 MW wind power generation facility in Silverton, Texas. The project comprises three phases: D1A (25 MW), and D1B (25 MW), and D2 (48 MW).

Project Dorothy is registered in one of the ERCOT's Demand Response Services ("DRS") programs. This designation positioned Project Dorothy as a contributor to grid flexibility and resilience in the Texas power market, while also enabling us to diversify our revenue streams.

Under the DRS program, we commit to maintaining a specified level of curtailment capacity—measured as load reduction availability—on a monthly basis. When called upon by ERCOT, we are required to reduce the facility's power consumption by the committed amount. In exchange, we receive compensation for maintaining this curtailment readiness, regardless of whether an actual dispatch occurs.

Participation in the program allows us to generate incremental revenue and offset power costs at Project Dorothy, enhancing its cost-efficiency. As a result, the facility ranks among the lowest-cost operators in the sector.

*Project Dorothy 1A*

D1A is focused on Bitcoin Hosting for some of the industry's hyperscale miners. For 2025, D1A completed all customer deployments and executed fleet upgrades across multiple hosting partners, driving measurable hashrate growth throughout the year.

D1A was constructed in partnership with SLC, a leading venture capital firm focused on sustainability solutions. SLC owns approximately 85% of the Class B Membership Units of D1A, while we own 15% of the Class B Membership Units of D1A and own 100% of the Class A Membership Units of D1A. After SLC achieves an 18% Internal Rate of Return hurdle, Soluna retains 50% of the profits on D1A.

*Project Dorothy 1B*

D1B is focused on proprietary Bitcoin Mining. D1B is co-owned by Navitas, which owns approximately 49% of D1B, while we own the remaining 51%. In 2025, fleet consolidation and reinvestment at D1B resulted in the deployment of 1,000 upgraded S19 XP miners, delivering hashrate gains and a strong competitive position heading into 2026.

*Project Dorothy 2* 

Project Dorothy 2 is a 48 MW expansion of the Company's Dorothy campus, which construction and commissioning were completed in 2025. The project was developed and energized in three phases (16 MW, 14 MW, and 18 MW), with initial commissioning beginning in the first quarter of 2025 and each phase brought online sequentially throughout the year, enabling customer deployments and revenue generation upon energization. By mid-August 2025, 32 MW was operational, with the remaining capacity commissioned in the fourth quarter. Construction was completed in November 2025, and the facility transitioned to full operations with all capacity deployed, operating at full capacity for the first full month in December 2025. Project Dorothy 2 is fully contracted with a mix of new and existing customers, including Blockware, Compass Mining, and a large-scale mining partner, and generates revenue through Bitcoin hosting and participation in demand response programs. D2 features a superior financial waterfall structure and enhanced management and development fees for Soluna compared to D1A, allowing us to benefit from improved income once the facility is operational.

Project Grace is a 2 MW project located at the D2 site focused on next generation data center designs for AI. It contemplates new direct liquid cooling technologies, proprietary building and power designs – called Helix. The Company is collaborating with Siemens, a leading technology company in electrification, automation and digitalization, to develop solutions addressing power demand fluctuations associated with AI workloads.

**Project Sophie**

Project Sophie is a 25 MW data center, based in Murray, Kentucky connected to the grid ("Sophie"). The project has a Power Purchase Agreement ("PPA") that requires the curtailment of the site during certain hours of the day to help balance the Kentucky grid. We own 100% of the facility, which was completed in 2021.

Sophie is focused on Bitcoin Hosting of multiple large customers. The data center generates revenue via a combination of fixed services fees and profit share, while energy cost is passed through. During 2025, Sophie completed three consecutive expansion agreements with long-standing hyperscale mining customers, reflecting sustained demand and high satisfaction with our hosting customers. In addition, Sophie closed a new 3.3 MW partnership with KULR Technology Group in October 2025, diversifying the customer base and expanding the site's renewable-powered computing footprint.

**Project Kati 1**

Project Kati 1 is the first phase of the Company's data center campus under development in Willacy County, Texas, co-located with a 272.6 MW wind farm. Project Kati 1 comprises 83 MW dedicated to Bitcoin hosting. Construction began on September 18, 2025, and on July 22, 2025, the Company finalized a contribution agreement with Spring Lane Capital for the initial 35 MW of capacity, with initial energization expected in the first half of 2026. Galaxy Digital has been secured as the initial customer for the project.

**Project Kati 2**

Project Kati 2 is the second phase of development at the Company's Kati site in Willacy County, Texas, and is focused on supporting AI and high-performance computing workloads. The project is being advanced through a joint venture with Metrobloks to develop an initial phase of 100 MW+ of AI and HPC capacity, with the potential to expand to a larger multi-hundred-megawatt deployment. The campus is designed to leverage behind-the-meter integration with renewable energy and support customers requiring large-scale, high-density compute infrastructure with accelerated time to power.

The project is currently advancing through land acquisition, power contract negotiation, and ERCOT interconnection planning.

***Our Growth Strategy***

Our growth strategy is focused on expanding our pipeline of renewable energy-powered data center projects and accelerating their development through joint ventures, co-ownership structures, and other strategic partnerships. Over time, we intend to increase our ownership stake in these projects to enhance long-term value.

Our renewable energy project pipeline—currently estimated at over 4.3 gigawatts (GW)—represents our most valuable strategic asset. We believe this pipeline has the potential to support the development of over 300 MW of new digital infrastructure annually over the next six to eight years.

In parallel with new project development, we are refining our operational model across existing sites to position ourselves as a partner of choice for both AI/HPC colocation and Bitcoin Hosting.

We continue to grow our pipeline by increasing the number of Curtailment Assessments completed with power generation partners. These assessments serve as a precursor to securing exclusive power purchase agreements (PPAs), acquiring or leasing land, and executing other pre-construction development activities necessary to advance projects to shovel-ready status.

In 2026, we are focused on advancing the following key initiatives:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Grow Pipeline:** Expand Soluna's Renewable Computing(™) pipeline by advancing projects in our 4.3 GW+ power pipeline to shovel-ready status and securing behind-the-meter access to curtailed energy resources. Enable scalable capacity with accelerated speed to power.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Develop AI**: Advance Project Kati 2 with Metrobloks to shovel-ready and tenant-ready. Build a pipeline of AI-ready campuses designed for rapid deployment from the 4.3GW+ pipeline through joint ventures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Optimize Projects:** Energize Project Kati 1. Enhance profitability across operating data centers through higher uptime, operational efficiency, and disciplined cost management, thereby strengthening long-term asset value and improving overall customer satisfaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Capital Formation:** Executing a disciplined capital strategy to fund pipeline growth, AI data center development, and construction. Leveraging project-level financing and strategic capital partnerships to scale data center development while maintaining balance sheet flexibility.

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

**Competition**

We operate in a highly competitive sector characterized by a growing number of participants and increasing capital investment. Our approach to sourcing renewable energy focuses on curtailed or underutilized power, which is typically priced below market rates. This enables us to offer competitively priced, sustainability-aligned computing solutions.

We believe one of our key strategic advantages is our model of co-locating data centers directly with renewable power generation assets. By building behind the meter, we are able to bypass long interconnection queues and source electricity directly from the generation site. This structure not only improves power economics, but also accelerates time-to-market—an increasingly important factor for companies with large, time-sensitive computing workloads such as AI and HPC.

We believe this combination of low-cost power access, grid efficiency, and sustainability focus positions us as a differentiated provider in the digital infrastructure space.

**Our emerging HPC Business** competes with leading data center firms such as Applied Digital, Digital Realty, NeoCloud companies such as Crusoe, CoreWeave, Lambda, FluidStack and Nebius. While some of these companies are much larger than we are today, we believe our competitive advantage lies in our ability to source renewable energy for the growth of this business faster and at better costs than our competitors.

**Our Bitcoin Hosting Business** competes with a large number of other hosting operators. We compete with public and private companies including: BitFuFu, Canaan, Cango, Blockstream, Blockware (who we have a dual relationship with), Foundry, Compass Mining (who we have a dual relationship with), Hut 8, Bitdeer, and Core Scientific. Our success in our hosting operations depends on our ability high quality data center facilities, best-in-class services, and industry leading power prices.

**Our proprietary Bitcoin Mining Business** competes globally to complete new blocks and earn Bitcoin rewards.

We may compete with the following publicly traded Bitcoin mining companies: Riot Platforms, Marathon Digital Holdings, Core Scientific, Cipher Mining, Hut 8 Mining, Hive Blockchain Technologies, Bitfarms, Bitdeer Technologies Group, Cleanspark, IREN, Bit Digital, TeraWulf, and Greenidge Generation Holdings.

Key competitive factors include our number of miners, mining difficulty, operational efficiency, and the fiat value of rewards. Bitcoin mining has shifted from individual participants to large-scale, industrial facilities. Mining pools allow participants to combine processing power and share rewards based on contributed hash power. We also compete for new miners, capital, and technological advancements to enhance mining efficiency.

Many of our competitors offer more locations in more markets worldwide and have well-established international operations. Many of our competitors may have significant advantages over us, including greater name recognition, longer operating histories and higher operating margins, pre-existing relationships with current or potential customers, the capacity to provide the same or additional products and services at a lower cost, more significant marketing budgets and other financial and operational resources, more robust internal controls and systems, and better established, more extensive scale and lower cost suppliers and supplier relationships.

We face significant competition from our competitors, and we expect such competition to continue to increase, which could significantly harm our business, financial condition, and results of operations. If we cannot compete successfully against our current and future competitors, we may not be able to retain and grow our customer base, and our business and prospects may be harmed.

**Intellectual Property**

We seek protection for our intellectual property as appropriate. To establish and protect our proprietary rights, we rely upon a combination of patent, copyright, trade secret and trademark laws and contractual restrictions such as confidentiality agreements and intellectual property assignment agreements.

As of the date of this Annual Report, Soluna has two issued US patents, three pending US patent applications with the U.S. Patent and Trademark Office, and four pending non-US patent applications. The non-US jurisdictions include Australia, Canada, China, European Patent Office ("EPO"), and Japan. Among other things, concepts in these patents/patent applications generally relate to modular architecture, cooling technology, data center control, simulation, variable power consumption and local co-optimization of power generation supply with demand. Specifically, the two issued patents

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

(US11,974,415 and US12,250,794) focus on the layout of modular data center buildings on a site, which is crucial for thermal efficiency.

We meet regularly with IP counsel to manage the portfolio and determine strategies to pursue protection of additional technologies. We maintain company policies requiring our employees, contractors, consultants and other third parties to enter into confidentiality and proprietary rights agreements to control access to our proprietary information. While there is no assurance that our pending applications will result in issued patents, we believe that our intellectual property portfolio provides us with a competitive advantage in our industry.

We also rely on trade secrets, proprietary know-how, and contractual agreements to protect our technology. However, our ability to maintain and enforce our intellectual property rights may be subject to challenges, including the risk of third-party disputes, opposition proceedings, and evolving patent laws in various jurisdictions. Loss of key patent rights or failure to obtain additional protections could adversely impact our business and competitive position.

We also hold a registered trademark for our Company name, Soluna.

We have developed a proprietary software system called MaestroOS™ to enable the automation, management, and operations of critical elements of our data centers. We have a dedicated team that engages in activities to continue to enhance the MaestroOS to drive innovation and growth in its business. MaestroOS incorporates software components licensed to the general public under open-source software licenses. We obtain many components from software developed and released by contributors to independent open-source components of our platform. Open-source licenses grant licensees broad permissions to use, copy, modify and redistribute those open-source components of our platform. As a result, open-source development and licensing practices can limit the value of our software copyright assets.

**Environmental**

Data centers, including those used for Bitcoin mining and AI workloads, are receiving increasing scrutiny regarding energy usage, carbon intensity, water consumption, land use and grid impacts. We seek to mitigate these concerns by colocating flexible computing loads with renewable energy resources and designing our facilities to use power and water more efficiently. However, the environmental benefits of our model may vary over time and depend on factors outside our control, including renewable resource availability, curtailment patterns, grid conditions, operating patterns and third-party assumptions and methodologies.

We may also face changing environmental laws, permitting requirements, water-use restrictions, emissions standards, climate-related disclosure obligations and other regulatory requirements that could increase costs, delay projects, require additional capital expenditures or limit operations. In addition, extreme weather, drought, heat, flooding and other climate-related events could reduce power availability, impair cooling efficiency, limit water access or disrupt our facilities. As AI and other high-density computing workloads expand, concerns over energy and water use may intensify, which could lead to additional public scrutiny, adverse publicity, permit challenges or operating restrictions. If we are unable to manage these risks effectively, our business, financial condition and results of operations could be materially adversely affected.

**Existing or Potential Governmental Regulations**

Cryptocurrency mining and related large-load computing activities are subject to an evolving regulatory framework at both the federal and state levels. Although the United States has not adopted a comprehensive federal statute governing cryptocurrency mining, federal and state agencies, grid operators, and policymakers have increased their focus on digital assets, electricity consumption, grid reliability, interconnection, environmental impacts, and related infrastructure planning. As a result, the regulatory environment applicable to our business is becoming more active and, in some respects, more prescriptive. The impact of future legislation, rulemaking, market rules, or enforcement actions on our operations remains uncertain and may vary by jurisdiction.

A substantial portion of our operations, including our Project Dorothy facilities, are located in Texas, which has historically maintained a comparatively favorable environment for digital asset mining and other large flexible loads. At the same time, Texas has increased its oversight of these facilities. In particular, Texas law and Public Utility Commission of Texas ("PUCT") rules now require certain virtual currency mining facilities in the ERCOT region that receive retail electric service and meet specified large-load and interruptibility thresholds to register with the PUCT. Existing facilities subject to the rule were required to register by February 1, 2025, and new facilities generally must register promptly after beginning service. In addition, ERCOT and the PUCT continued during 2025 and early 2026 to evaluate and refine interconnection

processes for large loads, including potential batch-study frameworks and related rule revisions intended to address study efficiency, transparency, cost allocation, and system reliability. These processes may affect the timing, cost, operating flexibility, or energization of existing and future projects, and we may experience delays or additional compliance burdens as those requirements evolve.

At the federal level, policy developments in 2025 generally reflected a more supportive posture toward digital assets and domestic infrastructure buildout, but they also signaled the potential for increased oversight. In January 2025, President Trump issued an executive order directing a federal working group to recommend a regulatory framework for digital assets. In March 2025, the President issued an executive order establishing a Strategic Bitcoin Reserve and a United States Digital Asset Stockpile. In July 2025, the White House released the working group's report on digital financial technology. During the same period, the federal government also increased its focus on electricity demand growth and infrastructure associated with large computing loads. For example, FERC in February 2025 initiated proceedings addressing colocation arrangements involving large loads such as AI-enabled data centers, and later opened a rulemaking process addressing the interconnection of large loads to the interstate transmission system, including questions regarding upgrade costs, reliability standards, and treatment of pending requests. Separately, the White House and the Department of Energy launched initiatives in 2025 aimed at accelerating permitting and power infrastructure needed to support AI-related demand growth. While many of these developments may benefit large-scale computing infrastructure, they could also result in new requirements, changed cost-allocation rules, expanded reporting obligations, or longer development timelines.

Although recent federal policy signals have generally been constructive for digital assets and large-scale computing infrastructure, the long-term regulatory trajectory remains uncertain. Other jurisdictions have taken or may take a more restrictive approach. For example, New York has continued to examine the environmental impacts of proof-of-work mining following its prior restrictions on certain fossil-fuel-based mining activity. We do not operate in New York, but similar legislation, permitting restrictions, environmental review requirements, grid-related rules, or market reforms in Texas or other jurisdictions could materially increase our costs, limit our operating flexibility, delay development, or otherwise adversely affect our business, financial condition, and results of operations. We continue to monitor legislative, regulatory, and market-rule developments at the federal, state, and ERCOT levels. For additional information on regulatory risks, see the section titled "Risk Factors" in this Annual Report.

**Human Capital Resources**

As of December 31, 2025, we had fifty-five (55) employees, including fifty-one (51) full-time employees, one (1) part-time employee, and three (3) full-time consultants. Of these employees, thirteen were in finance, twenty-six in operations, two in marketing, two in corporate development, six in information technology and engineering, two in human capital, two in power, and two executives. The operations personnel include both individuals directly involved in the strategy of our data centers as well as data center maintenance and supervisory roles. Certain positions within our organization require industry-specific technical knowledge. We have been successful in attracting and retaining qualified technical personnel for these positions.

None of our employees are subject to a collective bargaining agreement and we believe our relations with our employees to be positive, as reflected in our low voluntary turnover rate.

**Diversity, Equity, and Inclusion**

We support diversity and inclusion by ensuring a workplace where employees can thrive, and our policies are designed to promote equality and respect for everyone. Diverse backgrounds, experiences and opinions are encouraged and welcomed. In support of such diversity and inclusion, we act in accordance with our Code of Ethics and Business Conduct and our Non-Discrimination and Anti-Harassment Policy to create a safe environment free from discrimination or harassment that respects the human rights of our employees. We strive to achieve a workplace where opportunities for success are created and available for everyone equally.

**Item 1A. Risk Factors**

*An investment in our securities is highly speculative and involves a high degree of risk. We face a variety of risks that may affect our operations or financial results and many of those risks are driven by factors that we cannot control or predict. You should carefully consider the risks described below together with all of the other information in this Annual Report, including our consolidated financial statements and the related notes and the information described in the section entitled "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations," and in our other filings with the SEC. If any of the risks described below occur, our business, financial condition, results of operations and prospects could be materially adversely affected. In that case, the market price of our common stock would likely decline, and investors could lose all or a part of their investment. Only those investors who can bear the risk of loss of their entire investment should consider an investment in our securities. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our operations.*

***Summary Risk Factors***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our recurring losses from operations will require additional capital to support our business and objectives and grow our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have a limited operating history, and we may not recognize operating income in the future.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have financed our strategic growth primarily by issuing new shares of our common stock in public offerings and the issuance of debt, and plan to raise additional capital through similar offerings in the future, and our inability to do so on favorable terms may adversely affect our operations and the market price of our securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If we cannot achieve or maintain profitability, stockholders could lose all or part of their investment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our level of existing debt may negatively impact our liquidity, restrict our operations and ability to respond to business opportunities, and increase our vulnerability to adverse economic and industry conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may be unable to meet our remaining obligations under the terminated HPE Agreement (as defined below) which could lead to a default under that agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Joint ventures, joint ownership and strategic partner arrangements and other projects pose unique challenges, and we may not be able to fully implement or realize synergies, expected returns or other anticipated benefits associated with such projects.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may not be able to timely complete our future strategic growth initiatives or within our anticipated costs estimates, if at all.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our business plan is heavily dependent upon acquisitions and strategic alliances and our ability to identify, acquire or ally on appropriate terms, and successfully integrate and manage any acquired companies or alliances will impact our financial condition and operating results.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We are subject to risks associated with our need for significant electrical power.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Global economic and geopolitical events, policies and conflicts may adversely affect our business, financial condition and results of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may not be able to continue to develop our technology and keep pace with technological developments, or otherwise compete with other companies, many of which have greater resources and experience.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If we fail to effectively manage our growth, our business, financial condition, and results of operations could be harmed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our new services and changes to existing services could fail to attract or retain users or generate revenue and profits, or otherwise adversely affect our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have concentrated our operations and, thus, are particularly exposed to changes in the regulatory environment, market conditions and natural disasters in the state of Texas where our data centers are located.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our success depends on external factors affecting the Bitcoin industry.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our profitability depends in-part on Bitcoin prices and the stability of Digital Asset markets, which are highly volatile and largely unregulated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Regulatory changes or actions may alter the nature of an investment in us or restrict the use of cryptocurrencies in a manner that adversely affects our business, prospects, or operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Security breaches and irreversible transactions could result in the loss of our cryptocurrencies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Uncertainty around the adoption, use, and global demand for cryptocurrencies could adversely affect our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Because most of our and our hosted customers' miners are designed specifically to mine Bitcoin and may not be readily adaptable to mining other cryptocurrencies, a sustained decline in Bitcoin's value could adversely affect our business and results of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our data center business could be harmed by prolonged power outages, power and fuel shortages, capacity constraints and increases in power costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our reliance on a third-party pool service provider for our mining revenue payouts may have a negative impact on our operations. The same may be true in the case of our hosted customers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Declining block rewards, reliance on transaction fees, and network forks could adversely affect our mining operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Climate change and evolving regulations could adversely impact our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may be affected by price fluctuations in the wholesale and retail power markets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The development and acceptance of competing blockchain platforms or technologies may cause consumers to use alternative distributed ledgers or other alternatives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may be unable to secure, develop, finance, construct, commission and operate HPC and AI data center projects on the timetable or economics we expect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our HPC and AI data center business is subject to rapid changes in customer requirements, technology standards and infrastructure design, which may increase costs, delay development or make our facilities less competitive.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may be unable to procure, install or integrate specialized equipment required for HPC and AI workloads, including electrical, cooling, networking and other long-lead-time components, on acceptable terms or at all.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Tariffs, trade restrictions, import duties, export controls and other changes in trade policy may increase our capital costs, disrupt our supply chain and adversely affect the development and operation of our data centers..

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our business has and is expected to continue to have significant customer concentration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Failure to attract, grow and retain a diverse and balanced customer base, including key magnet customers, could harm our business and operating results.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We are heavily dependent on our senior management, and a loss of a member of our senior management team could cause the market prices of our securities to suffer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We depend upon third-party suppliers for power, and we are vulnerable to service failures and price increases by such suppliers and to volatility in the supply and price of power in the open market.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our business model depends upon the demand for data centers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Insiders continue to have substantial control over the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We are subject to complex environmental, health and safety laws and regulations that may expose us to significant liabilities for penalties, damages or costs of remediation or compliance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provisions in our Articles (as defined below), our Bylaws (as defined below), and Nevada law may discourage a takeover attempt even if a takeover might be beneficial to our stockholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If we are unable to protect our information systems against service interruption or failure, misappropriation of data or breaches of security, our operations could be disrupted, we could be subject to costly government enforcement actions and private litigation and our reputation may be damaged.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We incur significant costs as a result of operating as a public company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may become involved in litigation arising in the ordinary course of our business that may materially adversely affect us.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The market price of our securities is likely to be volatile, which may cause investment losses for our shareholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Because there has been limited precedent set for financial accounting of Bitcoin and other cryptocurrency assets, the determination that we have made for how to account for cryptocurrency assets transactions may be subject to change.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If we are not able to comply with the applicable continued listing requirements or standards of Nasdaq, Nasdaq could delist our common stock or Series A Preferred Stock or broker-dealers may be discouraged from effecting transactions in shares of our securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Substantial blocks of our common stock may be sold into the market as a result of our being party to the SEPA (as defined below) and you may experience immediate and substantial dilution in the net tangible book value per share of our common stock.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• It is not possible to predict the actual number of shares we will sell under the SEPA, or the actual gross proceeds resulting from those sales.

**Risks Relating to the Company and its Growth Strategy**

***Our recurring losses from operations will require additional capital to support our business and objectives and grow our business.***

We have incurred recurring losses since inception and, as of December 31, 2025, had an accumulated deficit of approximately $367.7 million. We anticipate operating losses to continue for the foreseeable future as we grow our business, and it is possible we will never achieve profitability.

Until such time as we can generate substantial revenue, we expect to finance our working capital requirements through a combination of equity offerings and debt financing. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making acquisitions or capital expenditures, or declaring dividends. If we are unable to raise additional funds through equity or debt financings or other arrangements when needed, we may be required to scale back or curtail our operations or expansion efforts, including limiting our ability to expand our hosting and cryptocurrency business to a larger-scale operation.

***We have a limited operating history and we may not recognize operating income in the future.***

We began our cryptocurrency and computer hosting operations in January 2020 and therefore our business is subject to all the risks inherent in a business with limited operating history in a rapidly developing and changing industry. Furthermore, in 2024 we began to implement a strategy to move into the HPC/AI hosting business to provide green energy to power-intensive AI applications, in an attempt to leverage our expertise in advanced data processing applications. This is a new strategic direction for the Company and we have no prior history of operations in either of these lines of business, from which we can evaluate our future operating performance in this segment. We have not yet been able to confirm that our business model can or will be successful over the long term, and we may not ever recognize operating income from this business. Our projections have been developed internally and may not prove to be accurate and our operating results will likely fluctuate moving forward as we focus on growing our operations. We may need to make business decisions that could adversely affect our operating results, such as modifications to our business structure or operations. There can be no assurance that we will be successful in either of these lines of business, which could significantly adversely affect our ability to scale the growth of our customer base or increase our revenue, which could have a material adverse effect on our results of operations in the future.

Given our status as an early operating stage company, without positive operating income, there is a substantial risk regarding our ability to succeed. You should consider our business and prospects in light of these risks and the risks and difficulties that we will encounter as we continue to develop our business model. We may not be able to address these risks and difficulties successfully, which would materially harm our business and operating results, and we could be forced to terminate our business, liquidate our assets and dissolve, and you could lose part or all of your investment.

***We have financed our strategic growth primarily by issuing new shares of our common stock in public offerings and the issuance of debt, and plan to raise additional capital through similar offerings in the future, and our inability to do so on favorable terms may adversely affect our operations and the market price of our securities.***

We have raised capital to finance the strategic growth of our business through public offerings of our common stock and the issuance of debt, and plan to raise additional capital through similar offerings to fund current and future expansion initiatives. We may not be able to secure additional debt or equity financing on favorable terms, if at all, which could hinder our growth and adversely impact our operations. In 2022 and 2023, a number of digital asset platforms and exchanges filed for bankruptcy and/or became the subjects of investigation by various governmental agencies for, among other things, fraud. These disruptions in the crypto asset market may impact our ability to obtain favorable financing. If we raise additional equity financing, stockholders may experience dilution of their ownership interests, and the per share value of our common stock could decline. If we are unable to generate sufficient cash flows to support our strategic growth, we may be required to adopt one or more alternatives, such as reducing or delaying investments or capital expenditures, selling assets, or obtaining additional equity financing on terms that may be onerous or highly dilutive. Furthermore, as we engage

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

in debt financing, in the event of bankruptcy, the holders of any debt we issue would likely have priority over the holders of shares of our common stock in terms of order of payment preference. We may be required to accept terms that restrict our ability to incur additional debt or take other actions, including accepting terms that require us to maintain specified liquidity or other ratios that could otherwise not be in the interests of our stockholders.

***If we cannot achieve or maintain profitability, stockholders could lose all or part of their investment*.**

We intend to continue scaling our company to increase our customer base and implement initiatives, including new business lines. As a result, we will incur increased costs associated with growth, expanding our customer base and being a public company. Our efforts to grow our business may be costlier than we expect, or the revenue growth rate may be slower than we expect and may not result in increased profitability in the short term or at all. As we pivot towards new markets such as the HPC/AI hosting business, our limited experience in these areas may impact our ability to accurately assess our prospects. The likelihood of our success must be considered in light of the expenses, difficulties, complications, problems, and delays frequently encountered in connection with the expansion of a business and operating a business in a competitive industry. There can be no assurance that we will ever operate profitably, and if we do, there can be no assurance that we would be able to maintain profitability. If we cannot achieve or maintain profitability, our stockholders could lose all or a part of their investment.

***Our level of existing debt may negatively impact our liquidity, restrict our operations and ability to respond to business opportunities, and increase our vulnerability to adverse economic and industry conditions.***

We currently use debt as part of our capital structure and may take on more debt in the future.

On June 20, 2024, we issued a $12.5 million secured promissory note, with approximately $7.8 million of principal outstanding as of December 31, 2025. This note, along with accrued interest, is due on June 20, 2027.

On March 12, 2025, Soluna SW, LLC, a subsidiary of Soluna Digital, Inc. ("SSW"), entered into a $5 million term loan with Galaxy Digital LLC under a loan agreement that matures on March 12, 2030, with approximately $4.6 million of principal outstanding as of December 31, 2025.

On September 12, 2025, we caused our subsidiaries, Soluna DVSL ComputeCo, LLC , Soluna DVSL II ComputeCo, LLC, and Soluna KK I ComputeCo, LLC (collectively, the "Borrowers") to enter into a Credit and Guaranty Agreement (the "Credit Agreement") with Generate Lending, LLC, as administrative agent and collateral agent (the "Agent"), and Generate Strategic Credit Master Fund I-A, L.P. (the "Lender"). The Credit Agreement provides for senior secured term loan commitments in an aggregate principal amount of up to $35.5 million, comprised of (i) Tranche A-1 ($5.5 million), (ii) Tranche A-3 ($11.5 million), and (iii) Tranche B ($18.5 million). In addition, the Credit Agreement permits the Borrowers to request one or more Additional Tranche Loan Commitments (as defined in the Credit Agreement), in the aggregate amount of up to $64.5 million, subject to the approval of the Lender and the Agent, for project-level financing of eligible projects. As of December 31, 2025, we have drawn $17.0 million and have approximately $16.2 million in principal outstanding.

Our current level of debt could limit our flexibility and pose risks to our business. It may:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Restrict our ability to raise new financing or make strategic investments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Require significant cash flows to cover interest and principal payments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Impose covenants that limit our ability to pay dividends, repurchase shares, make acquisitions, incur additional debt, or create liens;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Make us more vulnerable to downturns or limit our ability to pursue growth opportunities.

Our ability to manage our debt depends on our financial performance, which is subject to business and market conditions. If we fail to meet our debt obligations or violate covenants, lenders could declare defaults and accelerate repayment. This could trigger defaults on other obligations and, in the case of secured debt, lead to foreclosure on our assets. As of December 31, 2025, the Borrowers were not in compliance with the minimum Forward Contracted Debt Service Coverage Ratio covenant under the Credit Agreement. On March 26, 2026, the Agent provided a limited waiver of this covenant. There is no guarantee that we will be granted waivers in the future if we fail to meet our debt obligations or violate covenants.

We also provide guarantees for certain subsidiary debts. If called upon, we may need to cover those obligations, which could impact our cash position and require us to seek additional funding—potentially on unfavorable terms.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

To manage our debt, we may pursue refinancing options, which could include issuing new shares or convertible securities. This could dilute existing stockholders and reduce the market value of our stock.

***Soluna AL CloudCo, LLC, a wholly owned subsidiary of Soluna Cloud, Inc. may be unable to meet its remaining obligations under the terminated HPE Agreement which could lead to a default under that agreement.***

On March 24, 2025, Soluna AL CloudCo, LLC. notified Hewlett Packard Enterprise Company ("HPE") of its termination of the HPC & AI Cloud Services Agreement and HPE-Soluna Greenlake Statement of Work, dated June 18, 2024, entered into between Soluna AL CloudCo, LLC, a subsidiary of Soluna Cloud, Inc. ("CloudCo"), and HPE (together with the associated Statement of Work, the "HPE Agreement"). Under the HPE Agreement, we agreed to pay HPE an aggregate of $34 million payable over 36 months beginning June 2024, with $10.3 million pre-paid in June 2024 at contract execution and monthly payments of $667 thousand due until June 2027.

In accordance with the terms of the HPE Agreement, upon our notice of termination for convenience, the obligations under the HPE Agreement accelerated and the remaining payments of $19.3 million became immediately due and payable, including all upfront payments and monthly charges, plus any fees incurred for the terminated Services (as defined in the HPE Agreement). Due to the termination of the HPE Agreement, prepaid assets and other long-term assets were reduced by approximately $8.6 million, increased termination liability by approximately $20.0 million and recorded a loss on contract of approximately $28.6 million for the year ended December 31, 2024 to account for the termination and our contractual payments.

Subsequently, on March 26, 2025, HPE sent notice of its termination of the HPE Agreement for cause, effective immediately, due to CloudCo's material breach of its payment obligations that remained uncured for more than thirty (30) days. This default could result in a range of actions that could include legal or collections actions by HPE against CloudCo, any and all of which could have a material adverse effect on our business, financial condition, and results of operations.

On December 3, 2025, the Company was contacted by and provided information to a third party collection agent in connection with the HPE claim. The agency contacted the Company on January 15, 2026 to inform the Company that its engagement had been terminated. As of December 31, 2025, no formal legal proceedings have commenced, and the outstanding contract liability was approximately $19.3 million.

***We may be unable to refinance our indebtedness at maturity or the refinancing terms may be less favorable than the terms of our original indebtedness.***

It is likely that we will need to refinance at least a portion of our outstanding debt as it matures. If we are unable to refinance or extend principal payments due at maturity or pay them with proceeds of other capital transactions, then our cash flow may not be sufficient in all years to repay all such maturing debt and to pay distributions. Further, if prevailing interest rates or other factors at the time of refinancing result in higher interest rates upon refinancing, then the interest expense relating to that refinanced indebtedness would increase. Refinancing our indebtedness may also require us to expense previous debt issuance costs or to incur new debt issuance costs.

***Joint ventures, joint ownership and strategic partner arrangements and other projects pose unique challenges, and we may not be able to fully implement or realize synergies, expected returns or other anticipated benefits associated with such projects.***

From time to time, and as we expand our operations into the cloud and HPC/AI hosting business, we may be involved in strategic joint ventures and other joint ownership and strategic partnership arrangements. As of December 31, 2025, we had four primary project-level capital partners: SLC (equity), Navitas (equity), Galaxy (debt) and Generate (debt). We may not always be in complete alignment with our joint venture, joint owner or strategic partner counterparties; we may have differing strategic or commercial objectives and may be outvoted by our joint venture or other strategic partners, or we may disagree on governance matters with respect to the joint venture entity or the jointly owned assets. As a result, when we enter into joint ventures, joint ownership, and strategic partnership arrangements, we may be subject to a number of risks. In some joint ventures and joint ownership arrangements we may not be responsible for the operation of projects and will rely on our joint venture. joint owner or strategic partner counterparties for such services. Joint ventures, joint ownership and strategic partnership arrangements may also require us to expend additional internal resources that could otherwise be directed to other projects. If we are unable to successfully execute and manage our existing and any proposed joint venture and joint owner arrangements, it could adversely impact our financial and operating results. Our inability to successfully execute and manage our joint venture/joint owner/strategic partner arrangements could also significantly impact our expansion strategy as we are heavily dependent on these arrangements to finance the expansion of our operations**.**

***We may not be able to timely complete our future strategic growth initiatives or within our anticipated costs estimates, if at all.***

Our strategic growth initiatives may require construction, expansion or conversion of associated power facilities, which may expose us to significant risks that we may otherwise not be exposed to, including risks related to: construction delays; lack of availability of parts and/or labor; increased prices as a result, in part, of inflation, and delays for data center equipment; labor disputes and work stoppages, including interruptions in work due to pandemics or other public health crises; unanticipated environmental issues and geological problems; delays related to permitting and approvals to commence operations from public agencies and utility companies; delays in site readiness leading to our failure to meet commitments made in connection with such expansion; and delay or halts related to evaluations of strategic growth initiatives.

All construction-related projects depend on the skill, experience, and attentiveness of our personnel throughout the design and construction process. Should a designer, general contractor, subcontractor or key supplier experience financial difficulties or other problems during the design or construction process, we could experience significant delays, increased costs to complete the project and/or other negative impacts to our expected returns.

If we are unable to mitigate these risks and complete our growth initiatives on schedule and within our anticipated costs, such delays or implementation failures may hinder our ability to realize anticipated benefits, and our business and financial condition may suffer as a result.

***We may have difficulty in obtaining banking services for our cryptocurrency activities.***

While the banking authorities in the United States do not prohibit banks from providing banking services to cryptocurrency-related businesses such us, the Federal Reserve, the FDIC, and the Office of the Comptroller of the Currency have issued directives to banks in the United States relating to their crypto-asset risks and as a result a significant number of banks have determined to limit such activities. Accordingly, we have had and may have in the future, difficulty in opening bank accounts, obtaining letters of credit and generally accessing the banking system for our operational needs.

***Our business plan is heavily dependent upon acquisitions and strategic alliances and our ability to identify, acquire or ally on appropriate terms, and successfully integrate and manage any acquired companies or alliances will impact our financial condition and operating results.***

As part of our growth strategy, we may seek to acquire other businesses or form strategic alliances and partnerships that expand our market presence, complement our offerings, or provide access to new technologies. We may also need to do so to remain competitive. However, we may not be able to identify suitable opportunities, negotiate favorable terms, secure necessary financing, or successfully complete or integrate any such transactions.

Even when successful, acquisitions and partnerships carry significant risks, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Failure to realize expected benefits or synergies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Challenges integrating operations, systems, personnel, or cultures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Disruption to ongoing operations and diversion of management time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Loss of key employees, customers, or partners;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Incompatibility of business practices or internal controls;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Financial risks, including write-offs, increased expenses, or underperformance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Entry into unfamiliar markets with greater competition;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Potential liabilities or unforeseen costs; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Negative impacts on our financial results, including accounting and tax implications.

We may finance future deals by issuing equity or convertible debt, which could dilute existing stockholders or increase leverage.

Our strategic relationships, including those with SLC, Navitas, Galaxy and Generate or any future partnerships, must be well-managed to avoid harming our operations or results. There is no guarantee that any acquisition or alliance will achieve its intended goals or deliver the expected return, and differences in cost structures could cause fluctuations in our financial performance.

***We are subject to risks associated with our need for significant electrical power.***

Our operations currently require significant amounts of electrical power, and we anticipate our demand for electrical power will continue to grow as we continue to expand our mining fleet, and as we expand our business to implement our strategy to move into the cloud service business and HPC/AI hosting business. The fluctuating price of electricity required for our operations and to power our expansion may inhibit our profitability. If we are unable to continue to obtain sufficient electrical power on a cost-effective basis, we may not realize the anticipated benefits of our significant capital investments.

***Global economic and geopolitical events, policies and conflicts may adversely affect our business, financial condition, and results of operations.***

We may be exposed to price volatility and uncertainty in our supply chain due to geopolitical crises and economic downturns such as recessions, rising inflation, tariffs, social, political, and economic risks, conflicts and acts of war, sanctions and other restrictive actions by the United States and/or other countries. Changes in policy positions and priorities from the new U.S. government administration could increase this price volatility and uncertainty. Such crises will likely continue to influence our ability to do business in a cost-effective manner. Inflationary pressures, as well as disruptions in our supply chain, have increased the costs of goods, services, and personnel, which have in turn caused our capital expenditures and operating costs to rise. Additionally, these crises may discourage investment in Bitcoin and investors may shift their investments to less volatile assets. The effects of such global economic shifts, worsening inflationary issues, changes in policy, and geopolitical events could adversely affect our ability to access the capital and other financial markets, as such, we may be required to consider alternative sources of funding for our growth and operations which may increase our cost of capital. Such events and conditions could have a materially adverse effect on our business, operations, or financial results and the value of the Bitcoin we mine.

We may not be able to continue to develop our technology and keep pace with technological developments, or otherwise compete with other companies, many of which have greater resources and experience.

We currently lack the financial resources to compete directly with larger, well-funded companies in cryptocurrency mining and advanced data processing, including cloud, AI, and HPC data center operators. These markets attract major players with far greater capital and scale, making it difficult for us to expand or introduce new offerings.

Rapid changes in technology further increase this challenge. We may not be able to keep up with new developments, adopt new technologies quickly, or do so in a cost-effective way. Some of our equipment may become outdated, and upgrading or replacing it—especially mining hardware or advanced AI infrastructure—could be costly and time-consuming. Supply chain constraints, long lead times, and competition for key components like semiconductors could further limit our ability to stay current.

Implementing new technology may also lead to system disruptions or fail to deliver expected benefits. If we cannot adapt effectively, our competitiveness and growth prospects could suffer.

Additionally, other North American companies with greater access to low-cost energy may outcompete us in securing strategic acquisitions or partnerships. If we are unable to expand, innovate, or maintain our position in the market, it could negatively impact our business, financial condition, and the trading price of our securities.

***If we fail to effectively manage our growth, our business, financial condition, and results of operations could be harmed.***

We are an early operating stage company with a small management team and are subject to the strains of ongoing development and growth, which will place significant demands on our management and our operational and financial infrastructure. Although we may not grow as we expect, if we fail to manage our growth effectively or to develop and expand our managerial, operational, and financial resources and systems, our business and financial results could be materially harmed.

In addition, our failure to effectively manage our growth could damage our reputation, further limiting our growth and negatively affecting our operating results. Further, we cannot provide any assurance that we will successfully identify emerging trends and growth opportunities in this business sector, and we may lose out on opportunities. Such circumstances could have a material adverse effect on our business, prospects, or operations.

***Our new services and changes to existing services could fail to attract or retain users or generate revenue and profits, or otherwise adversely affect our business.***

Our ability to retain, increase, and engage our customer base and to increase our revenue depends heavily on our ability to continue to evolve our existing services and to create successful new services, both independently and in conjunction with developers or other third parties. We may introduce significant changes to our existing services or acquire or introduce new and unproven services, including using technologies with which we have little or no prior development or operating experience. These efforts, including the introduction of new services or changes to existing services, may result in new or enhanced governmental or regulatory scrutiny, litigation, ethical concerns, or other complications that could adversely affect our business, reputation, or financial results. If our new services fail to engage users or developers, or if our business plans are unsuccessful, we may fail to attract or retain users or to generate sufficient revenue, operating margin, or other value to justify our investments, and our business may be adversely affected.

***We have concentrated our operations and, thus, are particularly exposed to changes in the regulatory environment, market conditions and natural disasters in the state of Texas where our data centers are located.***

We currently operate data centers in Texas, which generated the majority of our revenue in both 2024 and 2025. Our growth plans also focus on new projects in Texas, making our business highly dependent on the state's regulatory environment, market conditions, and exposure to weather events or natural disasters.

Texas has supported Bitcoin mining through favorable regulations and economic incentives, but this has also led to increased competition for suitable sites and skilled labor. Our operations could be impacted by construction delays, rising costs for equipment or labor, supply chain disruptions, or disputes with contractors.

In 2022, ERCOT—the operator of Texas' power grid—began requiring large-scale digital asset miners to apply for grid connection approval and established a task force to review how large flexible loads (like Bitcoin data centers) interact with the grid. This has led to delays for some miners in getting energized, and we could face similar delays in the future.

If Texas were to change its policies, increase taxes, or reduce its support for Bitcoin mining, our concentration in the state could significantly affect our business, financial condition, and results of operations.

**Risks Related to our Bitcoin Mining and Hosting Business**

***Our success depends on external factors affecting the Bitcoin industry.***

Our success is closely tied to the health of the Bitcoin market, which is influenced by factors beyond our control. Historically, Bitcoin ownership has been concentrated among a small number of holders, often called "whales." Although ownership has become more distributed, large holders still exist and could impact the market by selling large amounts of Bitcoin, which may reduce demand and drive down prices.

While more regulated and transparent exchanges have emerged, the Bitcoin market remains relatively new and less regulated than traditional financial markets. Some trading platforms may be more prone to technical issues, fraud, or unethical practices such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Wash trading (creating artificial trading volume),

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Front-running (using early access to trade information for unfair advantage), and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Lack of transparency in ownership, governance, and compliance.

These issues may erode public trust in Bitcoin markets and lead to price volatility. A significant drop in the price or perceived reliability of Bitcoin could negatively impact our business and financial results.

***Our profitability depends on Bitcoin prices and the stability of Digital Asset markets, which are highly volatile and largely unregulated.***

Our ability to achieve and maintain profitability is closely tied to the market price of Bitcoin, which has historically been highly volatile and influenced by factors beyond our control. These include market speculation, global economic and political events, regulatory changes, energy prices, activity by large holders ("whales"), and technical or operational issues at major exchanges.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

Digital asset exchanges—where Bitcoin and other cryptocurrencies are traded—are relatively new and largely unregulated. Many lack transparency in ownership, management, and compliance practices. This has led to market instability, particularly when major exchanges have collapsed, faced hacking incidents, or become subject to regulatory investigations. Notable examples include the collapse of FTX and scrutiny of Binance, which contributed to sharp price declines and increased negative publicity across the cryptocurrency industry. The price of Bitcoin has experienced substantial historical volatility, including its recent decline beginning in October 2025, and may continue to fluctuate widely due to a variety of factors, including the actions of malicious or manipulative actors, perceived or actual scarcity, political or economic developments, regulatory changes, and market speculation that may contribute to "bubble"-type price dynamics.

A lack of trust in digital asset exchanges or their closure—whether due to fraud, government action, or business failure—can further undermine public confidence in Bitcoin, increase market volatility, and negatively impact our business. These risks may continue to evolve in ways we cannot fully anticipate.

In addition, Bitcoin has a fixed supply of 21 million coins, with about 20.0 million already mined as of December 31, 2025. As block rewards decline through scheduled "halvings" and eventually phase out, our revenue from mining will increasingly rely on transaction fees. While these fees have grown, there is no guarantee they will be sufficient to support profitability in the long term.

Volatility also affects how much revenue we realize from converting mined Bitcoin into U.S. dollars and makes financial planning more difficult. A prolonged decline in Bitcoin prices could also affect the ability of our co-hosting customers to pay for services, reducing our revenue and delaying expansion.

If Bitcoin prices fall or fail to meet our expectations, or if instability in the broader digital asset market increases, our financial condition and results of operations could be materially and adversely affected.

***Regulatory changes or actions may alter the nature of an investment in us or restrict the use of cryptocurrencies in a manner that adversely affects our business, prospects, or operations.***

The regulatory environment for cryptocurrencies is evolving and uncertain. Governments around the world have taken varied approaches—some banning cryptocurrencies entirely, others permitting them with little restriction, and many (including the U.S.) applying complex and changing rules to mining, ownership, and trading.

In the U.S., regulatory momentum has increased. In January 2025, President Trump issued an executive order to create a federal framework for digital assets, and Congress has formed bipartisan working groups to pursue legislation on the topic. Discussions have included creating a national digital asset reserve that could include Bitcoin, and multiple states have proposed similar reserves. Additionally, in March 2025, the U.S. established the U.S. Bitcoin Strategic Reserve, which is reported to hold the largest Bitcoin reserve in the world, and at least twelve states have introduced legislation to create strategic Bitcoin reserves. Notably, in June 2025, the Governor of the State of Texas signed into law the Texas Strategic Bitcoin Reserve and Investment Act, making Texas the first state to formally establish such a reserve. In January 2026, new legislation was filed in Texas to expand the reserve's scope to include other major digital assets. While these developments may ultimately bring more clarity, their outcomes remain uncertain.

Past actions have shown that regulation can also become more restrictive. For example:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In November 2022, New York banned new fossil fuel permits for proof-of-work mining.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In January 2024, the SEC approved spot Bitcoin ETFs, leading to increased institutional adoption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In February 2024, the EIA launched, then suspended, a survey to monitor electricity use in crypto mining. The long-term regulatory impact of that effort remains unclear.

Although some recent enforcement actions have been scaled back, future regulations—especially those targeting electricity use, financial reporting, or market oversight—could increase our compliance burden, restrict our operations, or affect demand for our services.

Given this uncertainty, we cannot predict how future laws or agency actions may impact our business. Even well-intentioned or positive regulatory initiatives could have unintended consequences that negatively affect our operations, financial condition, or growth prospects.

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

***Our interactions with a blockchain may expose us to specially designated nationals ("SDNs") or blocked persons and new legislation or regulation could adversely impact our business or the market for cryptocurrencies.***

The Office of Foreign Assets Control ("OFAC") of the U.S. Department of Treasury requires us to comply with its sanction program and not conduct business with persons named on its SDN list. However, because of the pseudonymous nature of blockchain transactions we may inadvertently and without our knowledge engage in transactions with persons named on OFAC's SDN list. Our policy prohibits any transactions with such SDN individuals, but we may not be adequately capable of determining the ultimate identity of the individual with whom we transact with respect to selling cryptocurrency assets. We are unable to predict the nature or extent of new and proposed legislation and regulation affecting the cryptocurrency industry, or the potential impact of the use of cryptocurrencies by SDN or other blocked or sanctioned persons, which could have material adverse effects on our business and our industry more broadly. Further, we may be subject to investigation, administrative or court proceedings, and civil or criminal monetary fines and penalties as a result of any regulatory enforcement actions, all of which could harm our reputation and affect the value of our securities.

***Security breaches and irreversible transactions could result in the loss of our cryptocurrencies.***

Our operations rely on third-party platforms such as the Luxor mining pool and exchanges like Coinbase to store and manage our cryptocurrencies. Like others in the industry, we face risks from security breaches, including hacking, malware, or insider error. A successful attack on our systems or those of our partners could result in the theft or loss of our digital assets, compromise confidential information, disrupt operations, and damage our reputation.

Additionally, cryptocurrency transactions are typically irreversible. If coins are accidentally sent to the wrong address or stolen through fraud or theft, we may have no way to recover them. Any such losses—whether from security incidents or transactional errors—could negatively affect our business, financial condition, and results of operations, and may also impact investor confidence.

***Uncertainty around the adoption, use, and global demand for cryptocurrencies could adversely affect our business.***

Our business depends on the continued demand for, and value of, cryptocurrencies—particularly Bitcoin—which is influenced by a variety of factors, including adoption, usability, and global economic and geopolitical events. However, the future of cryptocurrency as a widely used payment method remains uncertain.

Despite growing awareness, cryptocurrencies face major adoption and scaling challenges. High transaction costs, slow processing times, and limited throughput have restricted their use in everyday transactions. Although efforts are underway to address these issues through protocol upgrades and second-layer technologies, there is no assurance that such solutions will succeed or gain broad acceptance. If these problems persist, demand for cryptocurrencies may decline, reducing the viability of mining and the need for services like ours.

Additionally, most cryptocurrency demand today is driven by investment and speculation rather than retail or commercial use. Widespread acceptance as a medium of exchange has not occurred—and may never occur. If adoption stalls or declines, the value of the cryptocurrencies we or our hosted customers mine could drop, impacting our revenues and growth prospects.

Geopolitical and economic events also create uncertainty. Crises can lead to sudden surges in demand, driving up prices temporarily, but also increasing the risk of sharp price declines once the crisis subsides. Alternatively, in times of global instability or economic downturns, investors may shift away from volatile assets like cryptocurrencies toward more traditional safe-haven investments, weakening demand further.

Taken together, these factors could materially impact our business, financial condition, and the long-term sustainability of our operations.

***Because most of our and our hosted customers' miners are designed specifically to mine Bitcoin and may not be readily adaptable to mining other cryptocurrencies, a sustained decline in Bitcoin's value could adversely affect our business and results of operations*.**

We and our hosted customers have invested substantial capital in acquiring miners designed specifically to mine Bitcoin as efficiently and as rapidly as possible on our assumption that we will be able to use them to mine Bitcoin and generate revenue from our operations. Therefore, our mining and hosting operations focus primarily on mining Bitcoin, and our

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

revenue is largely based on the value of Bitcoin. Accordingly, if the value of Bitcoin declines and fails to recover, for example, because of the development and acceptance of competing blockchain platforms or technologies, including competing cryptocurrencies which our miners or our customers' miners may not be able to mine, the revenue we generate from our operations will likewise decline. Moreover, we may not be able to successfully repurpose our operations in a timely manner, if at all, if we or our customers decide to switch to mining a different cryptocurrency (or to another purpose altogether) following a sustained decline in Bitcoin's value or if Bitcoin is replaced by another cryptocurrency. This could have a material adverse effect on our business, prospects, operations, and financial condition, as well as on the market value of our securities.

***Our data center business could be harmed by prolonged power outages, power and fuel shortages, capacity constraints and increases in power costs.***

Our data centers rely on consistent, high-capacity electricity supply, and any disruption—planned or unplanned—could negatively impact our operations and customer experience. Power outages caused by storms, fires, cyberattacks, utility failures, or infrastructure issues may lead to downtime and revenue loss. In some leased facilities, we may depend on landlords or utility providers to restore power, limiting our control in an outage.

While we may use backup generators and other measures to reduce downtime, they may not always be sufficient. Additionally, as customer equipment becomes more power-intensive, total energy consumption at our facilities may exceed original design expectations, potentially limiting available capacity and future growth.

We also face rising electricity costs driven by global energy market volatility, including supply disruptions from the Russia-Ukraine conflict, increased seasonal demand, and broader macroeconomic pressures. Over time, electricity prices may continue to rise due to climate change impacts, new environmental regulations, or our use of renewable energy. These cost increases could materially affect our financial condition, operating results, and cash flows.

***Our properties may experience damages, including damages that are not covered by insurance.***

Our properties are subject to a variety of risks relating to physical condition and operation, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the presence of construction or repair defects or other structural or building damage;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any noncompliance with or liabilities under applicable environmental, health or safety regulations or requirements or building permit requirements; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any damage resulting from natural disasters, such as hurricanes, earthquakes, fires, floods, and windstorms.

For example, our facilities could be rendered inoperable, temporarily, or permanently, as a result of a fire or other natural disaster or by a terrorist or other attack on the site. The security and other measures we take to protect against these risks may not be sufficient. Additionally, our processing equipment could be materially adversely affected by a power outage, loss of access to the electrical grid, or loss by the grid of cost-effective sources of electrical power generating capacity. Given the power requirement, it would not be feasible to run miners on back-up power generators in the event of a power outage. Our insurance covers the replacement cost of any lost or damaged miners but does not cover any interruption of our mining activities; our insurance therefore may not be adequate to cover the losses we suffer as a result of any of these events. In the event of an uninsured loss, including a loss in excess of insured limits, at any of the mines in our network, such mines may not be adequately repaired in a timely manner or at all and we may lose some or all of the future revenues anticipated to be derived from such mines.

***Our reliance on a third-party mining pool service provider for our mining revenue payouts may have a negative impact on our operations. The same may be true in the case of our hosted customers.***

We currently rely on Luxor's mining pool that supports Bitcoin to receive our mining rewards and fees from the network. Our mining pool has the sole discretion to modify the terms of our agreement at any time, and, therefore, our future rights and relationship with our mining pool may change. In general, mining pools allow miners to combine their computing power, increasing their chances of solving a block and getting paid by the network. The rewards are distributed by the mining pool operator, proportionally to our contribution to the mining pool's overall mining power, used to generate each block. Should the mining pool operator's system suffer downtime due to a cyber-attack, software malfunction, or similar issues, it will negatively impact our ability to mine and receive revenue. Furthermore, we and many other Bitcoin miners

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

are dependent on the accuracy of the mining pool operator's recordkeeping to accurately record the total processing power provided to the mining pool for a given Bitcoin mining application in order to assess the proportion of that total processing power we provided. While we have internal methods of tracking both our power provided and the total used by the mining pool, the mining pool operator uses its own recordkeeping to determine our proportion of a given reward. We and other miners have little means of recourse against the mining pool operator if we determine that the proportion of the reward that the mining pool operator pays out to us is incorrect, other than leaving the mining pool. If we are unable to consistently obtain accurate proportionate rewards from our mining pool operator, we may experience reduced reward for our efforts, which would have an adverse effect on our results of operations and financial condition.

***Declining block rewards, reliance on transaction fees, and network forks could adversely affect our mining operations.***

Our ability to generate revenue from Bitcoin mining depends on rewards received for solving new blocks. These rewards are designed to decrease over time through regularly scheduled "halvings." For example, the most recent halving on April 19, 2024, reduced the reward from 6.25 to 3.125 Bitcoin per block. This process will continue roughly every four years until the total supply reaches 21 million Bitcoin, expected around the year 2140.

If the price of Bitcoin does not increase proportionally—or if mining difficulty does not decrease—halvings may reduce our mining revenue and profitability. This may also impact our hosted customers, whose ability to cover operating costs depends on the value of rewards earned. Over time, the Bitcoin network is expected to rely more on transaction fees instead of block rewards. However, if those fees are not high enough to support ongoing mining activity, it could reduce incentives to mine and weaken the network's stability. Conversely, if transaction fees rise too high, users may avoid using Bitcoin, reducing transaction volume and fee opportunities.

If the aggregate computing power or hash rate on the Bitcoin network increases significantly, for proprietary Bitcoin mining, we may incur elevated capital expenses to maintain and upgrade our mining fleet in order to maintain market share.

In addition, we face risks from network "forks", where a blockchain splits into two incompatible versions—usually due to changes in protocol adopted by only part of the network. Forks can lead to the creation of new cryptocurrencies and may cause confusion, market volatility, or incompatibility with existing mining equipment. If we are unable to support both versions or secure the economic benefit of the new asset, our operations and financial results could be negatively affected. Forks can also expose our systems to cybersecurity risks and disrupt mining activity.

Together, declining rewards, uncertain transaction fee dynamics, and network forks pose significant risks to our mining business, which could materially impact our revenue, profitability, and overall financial condition.

***Climate change and evolving regulations could adversely impact our business.***

Our operations depend heavily on access to reliable and cost-effective electricity. As a result, our business is exposed to both the physical effects of climate change and the potential for new environmental and energy regulations. Physical risks—such as extreme weather, water shortages, and temperature changes—could disrupt our data centers, damage infrastructure, or impair our ability to operate efficiently, particularly in regions like Texas where we have significant operations.

The lack of consistent regulation also creates uncertainty, especially as investor groups, policymakers, and the public increasingly scrutinize companies for their environmental practices.

Additionally, future regulatory changes could affect our business planning and capital investment decisions. For example, assumptions we have made about the regulatory landscape—such as for our Dorothy facility—may change, resulting in unexpected costs or challenges in execution. In Texas, we currently participate in demand response programs to reduce

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

strain on the grid during high-demand periods. While beneficial today, future regulatory changes could impact our ability to participate in or benefit from such programs.

Given the uncertainty surrounding climate change policy and energy regulation, we cannot predict how these issues will evolve or the long-term effects on our operations. However, any of the risks described above could materially impact our financial condition, operating performance, and ability to compete.

***We may be affected by price fluctuations in the wholesale and retail power markets.***

While the majority of our power and hosting arrangements contain fixed power prices, some also contain certain price adjustment mechanisms in case of certain events. Furthermore, a portion of our power and hosting arrangements includes merchant power prices, or power prices reflecting market movements. Market prices for power, generation capacity and ancillary services are unpredictable. Over the past year, the market prices for power have generally been increasing, driven in part by the price increases in various commodities, including natural gas. Depending upon the effectiveness of any price risk management activity undertaken by us, an increase in market prices for power, generation capacity, and ancillary services may adversely affect our business, prospects, financial condition, and operating results. Long- and short-term power prices may fluctuate substantially due to a variety of factors outside of our control, including, but not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increases and decreases in generation capacity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in power transmission or fuel transportation capacity constraints or inefficiencies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• volatile weather conditions, particularly unusually hot or mild summers or unusually cold or warm winters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• technological shifts resulting in changes in the demand for power or in patterns of power usage, including the potential development of demand-side management tools, expansion and technological advancements in power storage capability and the development of new fuels or new technologies for the production or storage of power;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• federal and state power, market and environmental regulation and legislation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in capacity prices and capacity markets.

If we are unable to secure power supply at prices or on terms acceptable to us, it would have a material adverse effect on our business, financial condition, operating results, and prospects.

***The development and acceptance of competing blockchain platforms or technologies may cause consumers to use alternative distributed ledgers or other alternatives.***

The development and acceptance of competing blockchain platforms or technologies may cause consumers to abandon Bitcoin. As we exclusively mine Bitcoin, and expect to exclusively mine Bitcoin in the future, we could face difficulty adapting to emergent digital ledgers, blockchains or alternatives thereto. This could prevent us from realizing the anticipated profits from our investments. Such circumstances could have a material adverse effect on our business, prospects, or operations and potentially the value of any Bitcoin we mine or otherwise acquire or hold for our own account and therefore harm investors.

***We have an evolving business model which is subject to various uncertainties.***

As crypto assets and blockchain technologies become more widely available, we expect the services and products associated with them to evolve. Future regulations may require us and our co-hosting customers to change our or their business in order to comply fully with federal and state laws regulating crypto asset (including Ethereum and Bitcoin) mining. In order to stay current with the industry, our business model may need to continue to evolve as well. From time to time, we may modify aspects of our business model relating to our strategy. We cannot offer any assurance that these or any other modifications will be successful or will not result in harm to our business.

**Risks Related to our HPC/AI Business**

***We may be unable to secure, develop, finance, construct, commission and operate HPC and AI data center projects on the timetable or economics we expect.***

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

Our strategy includes the development and operation of data centers for high performance computing ("HPC"), artificial intelligence ("AI") and other advanced compute workloads. These projects are capital-intensive, technically complex and depend on the successful coordination of site control, permitting, power availability, design, procurement, customer contracting, financing, construction, commissioning and operations. Each stage involves substantial uncertainty and may be affected by factors outside our control, including regulatory approvals, market conditions, customer timing, contractor performance, supply chain disruptions, labor availability and the cost and availability of capital. Delays, cost overruns or operating shortfalls could increase our capital needs, defer revenue, reduce expected returns or cause us to abandon projects. If we are unable to execute these projects on the timetable or economics we expect, our business, financial condition and results of operations could be materially adversely affected.

***Our HPC and AI data center business is subject to rapid changes in customer requirements, technology standards and infrastructure design, which may increase costs, delay development or make our facilities less competitive.***

The markets for HPC and AI infrastructure are evolving rapidly. Customer requirements may change quickly with respect to power density, cooling architecture, rack design, network configuration, resiliency standards, security and deployment timelines. Advances in semiconductors, systems architecture, model efficiency and data center design may also change the infrastructure needed to support these workloads. As a result, facilities designed based on current assumptions may require redesign, retrofitting or additional capital to remain commercially attractive. If we do not anticipate and respond to these changes in a timely and cost-effective manner, our development timelines may be extended, our costs may increase and our facilities may become less competitive.

***We may be unable to procure, install or integrate specialized equipment required for HPC and AI workloads, including electrical, cooling, networking and other long-lead-time components, on acceptable terms or at all.***

The development and operation of HPC and AI data centers depend on the timely availability of specialized equipment and materials, including transformers, switchgear, generators, cooling systems, liquid cooling components, network equipment, fiber infrastructure, control systems and other critical components. Many of these items have long lead times, are available from a limited number of suppliers or are subject to allocation, pricing pressure, transportation constraints or import-related disruptions. Even when equipment is available, installation and integration may be delayed by design changes, contractor performance, site conditions, commissioning issues or interoperability challenges. Failure to procure, install or integrate this equipment on schedule and on acceptable terms could delay project completion, increase costs, limit capacity, impair performance or reduce profitability.

***Tariffs, trade restrictions, import duties, export controls and other changes in trade policy may increase our capital costs, disrupt our supply chain and adversely affect the development and operation of our data centers.***

Our business depends on equipment, materials and components that may be sourced, directly or indirectly, from foreign manufacturers or suppliers, including electrical equipment, cooling systems, generators, transformers, switchgear, networking equipment, semiconductors, servers and other specialized infrastructure. Changes in tariffs, import duties, trade restrictions, export controls, sanctions, customs rules or other trade policies may increase the cost of these items, reduce availability, lengthen delivery times or otherwise disrupt our supply chain. These measures may also increase our suppliers' and contractors' costs and create broader market uncertainty that delays customer decisions or infrastructure investment. If we cannot mitigate these impacts through pricing, sourcing alternatives or contractual protections, our capital expenditures, operating costs, development timelines and project economics could be materially adversely affected.

**Risks Related to our Company Generally**

***Our business has and is expected to continue to have significant customer concentration***.

We generate a large portion of our revenue from a small number of customers. If we were to lose one or more of our large customers, our operating results could suffer dramatically. There can be no assurance that if we lose a major customer in the future, we will be able to successfully replace such customer in a timely manner, or at all, without any significant impact to our results of operations.

We expect that the limited number of customers will continue to account for a high percentage of our revenue for the foreseeable future. In addition, demand for our services generated by these customers may fluctuate significantly from quarter to quarter. The concentration of our customer base increases risks related to the financial condition of our

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

customers, and the deterioration in financial condition of a single customer or the failure of a single customer to perform its obligations could have a material adverse effect on our results of operations and cash flow. If a subset or all of our customers were to experience harm or loss due to unforeseen circumstances, it could negatively impact their businesses. In the event that any of our customers experience a decline in their equipment usage for any reason, or decide to discontinue the use of our facilities, we may be compelled to lower our lease prices or risk losing a significant customer. Such developments could adversely affect our profit margins and financial position, leading to a negative impact on our revenue and operating results.

***Failure to attract, grow and retain a diverse and balanced customer base, including key magnet customers, could harm our business and operating results.***

Our ability to attract, grow and retain a diverse and balanced customer base, consisting of enterprises, cloud service providers, network service providers, and digital economy customers, some of which we consider to be key magnets drawing in other customers, may affect our ability to maximize our revenues. Dense and desirable customer concentrations within a facility enable us to better generate significant interconnection revenues, which in turn increases our overall revenues. In the future, our ability to attract customers to our data centers will depend on a variety of factors, including our product offerings, the presence of carriers, the overall mix of customers, the presence of key customers attracting business through ecosystems, the data center's operating reliability and security and our ability to effectively market our product offerings. Our inability to develop, provide or effectively execute any of these factors may hinder the development, growth and retention of a diverse and balanced customer base and adversely affect our business, financial condition, and results of operations.

***We are heavily dependent on our senior management, and a loss of a member of our senior management team could cause the market prices of our securities to suffer.***

If we lose the services of John Belizaire, our Chief Executive Officer and member of our board of directors, and/or certain key employees, we may not be able to find appropriate replacements on a timely basis, and our business could be adversely affected. We do not currently maintain key life insurance policies on these officers or key employees. Our existing operations and continued future development depend to a significant extent upon the performance and active participation of these individuals and certain key employees. We may not be successful in retaining the services of these individuals, and if we were to lose any of these individuals, we may not be able to find appropriate replacements on a timely basis and our financial condition and results of operations could be materially adversely affected.

***We depend upon third-party suppliers for power, and we are vulnerable to service failures and price increases by such suppliers and to volatility in the supply and price of power in the open market.***

Our data centers depend on third-party utility providers for electricity. If these providers fail to deliver sufficient power—due to supply shortages, outages, or delays in adding new capacity—our operations and customer service could be disrupted. Power outages, even temporary ones, may exceed the limits of our backup systems, potentially damaging equipment, harming customer relationships, and impacting our ability to generate revenue.

We are also exposed to rising and unpredictable energy costs. Power prices may increase due to fuel cost volatility (e.g., natural gas or coal), carbon regulations, grid modernization fees, recovery charges from extreme weather events, or geopolitical instability. Higher power costs at specific sites could make those data centers less competitive compared to others with cheaper electricity.

In some cases, we have entered long-term power purchase agreements (PPAs) for renewable energy and credits at fixed prices. If market prices fall, we may pay more under these agreements than we would on the open market. Additionally, disruptions to our renewable energy suppliers—such as from extreme weather or equipment failure—could limit our access to renewable energy or credits.

Any of these issues—supply failures, price increases, or contract imbalances—could materially affect our business, operations, and financial results.

***Our confidentiality agreements with employees and others may not adequately prevent disclosure of our trade secrets and other proprietary information, which could limit our ability to compete.***

In addition to the protection afforded by patents, we rely on trade secrets to protect much of our proprietary technology and processes. Despite such protection, however, it is possible that a third party may copy or otherwise obtain and use our proprietary information without our authorization and trade secrets can be difficult to protect. Policing unauthorized use of our intellectual property and trade secrets is difficult, particularly in light of the global nature of the Internet and because the laws of other countries may afford us little or no effective protection of our intellectual property. Potentially expensive litigation may be necessary in the future to enforce our intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement or invalidity. Additionally, we enter into confidentiality and intellectual property assignment agreements with our employees, consultants, and other advisors. These agreements generally require that the other party keep confidential and not disclose to third parties' confidential information developed by the party under such agreements or made known to the party by us during the course of the party's relationship with us. Our employees, consultants, and other advisors, however, may not honor these agreements and enforcing a claim that a party illegally obtained and is using our trade secrets is difficult, expensive and time-consuming and the outcome is unpredictable. Our failure to obtain and maintain trade secret protection could adversely affect our competitive position.

***We may not be able to compete with other companies, some of which have greater resources and experience.***

We may not be able to compete successfully against present or future competitors. We do not have the resources to compete with larger providers of similar products or services at this time. The crypto asset industry (mining and hosting) as well as the cloud and AI/HPC industry has attracted various high-profile and well-established operators, some of which have substantially greater liquidity and financial resources than we do. With the limited resources we have available, we may experience great difficulties in expanding and improving our services and product offerings to remain competitive. Competition from existing and future competitors, particularly those that have access to competitively priced energy, could result in our inability to secure acquisitions and partnerships that we may need to expand our business in the future. This competition from other entities with greater resources, experience and reputations may result in our failure to maintain or expand our business, as we may never be able to successfully execute our business plan. If we are unable to expand and remain competitive, our business could be negatively affected which would have an adverse effect on our business, results of operations, financial condition, and the trading price of our common stock, which would harm our investors.

***Our business model depends upon the demand for data centers.***

We intend to be in the business of owning, leasing and operating data centers. A reduction in the demand for data center space, power or connectivity would have an adverse effect on our business and financial condition. We are susceptible to general economic slowdowns as well as adverse developments in the data center, internet and data communications and broader technology industries. Any such slowdown or adverse development could lead to reduced corporate information technology ("IT") spending or reduced demand for data center space. Reduced demand could also result from business relocations, including to markets that we do not currently serve. Changes in industry practice or in technology could also reduce demand for the physical data center space we provide. In addition, our customers may choose to develop new data centers or expand their own existing data centers or consolidate into data centers that we do not own or operate, which could reduce demand for our data centers or result in the loss of one or more key customers. If any of our key customers were to do so, it could result in a reduction in our revenues and/or put pressure on our pricing. If we lose a customer, we may not be able to replace that customer at a competitive rate or at all. Mergers or consolidations could further reduce the number of our customers and potential customers and make us more dependent on a more limited number of customers. If our customers merge with or are acquired by other entities that are not our customers, they may discontinue or reduce the use of our data centers in the future. Our financial condition, results of operations, cash flows and ability to satisfy our debt service obligations could be materially adversely affected as a result of any or all of these factors.

***We rely on highly skilled personnel and the continuing efforts of our executive officers and, if we are unable to retain, motivate or hire qualified personnel, our business may be severely disrupted. In addition, increased labor costs and the unavailability of skilled workers could hurt our business, financial condition, and results of operations.***

Our performance largely depends on the talents, knowledge, skills, know-how and efforts of highly skilled individuals Our future success depends on our continuing ability to identify, hire, develop, motivate, and retain highly skilled personnel for all areas of our organization. Our continued ability to compete effectively depends on our ability to attract, among others, new technology developers and to retain and motivate our existing contractors. If one or more of our key personnel are

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

unable or unwilling to continue in their present positions, we may not be able to replace them readily, if at all. In such cases, our business may be severely disrupted, and we may incur additional expenses to recruit and retain new officers or other key personnel. In addition, if any of our executives or key personnel joins a competitor or forms a competing company, we may lose customers.

In addition, we compete with other businesses in our industries and other similar employers to attract and retain qualified personnel with the technical skills and experience required to successfully operate our businesses. The demand for skilled workers is high and the supply is limited, and a shortage in the labor pool of skilled workers or other general inflationary pressures or changes in applicable laws and regulations could make it more difficult for us to attract and retain personnel and could require us to enhance our wage and benefits packages, which could increase our operating costs.

***Insiders continue to have substantial control over the Company.***

As of December 31, 2025, the Company's directors and executive officers held the current right to vote approximately 23% of the Company's outstanding voting stock. In addition, the Company's directors and executive officers have the right to acquire additional shares of our common stock by exercising their equity awards under our equity compensation plans, which could increase their voting percentage significantly. As a result, many of the Company's officers and directors acting together, may have the ability to exert significant control over the Company's decisions and control the management and affairs of the Company, and also to determine the outcome of matters submitted to stockholders for approval, including the election or removal of a director, and any merger, consolidation, or sale of all or substantially all of the Company's assets. Accordingly, this concentration of ownership may harm the future market prices of our securities by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• delaying, deferring, or preventing a change in control of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• impeding a merger, consolidation, takeover, or other business combination involving the Company; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of the Company.

***We are subject to complex environmental, health and safety laws and regulations that may expose us to significant liabilities for penalties, damages or costs of remediation or compliance.***

We are subject to various federal, state, local and foreign environmental, health and safety laws and regulations. These laws and regulations govern matters such as: the emission and discharge of hazardous materials into the ground, air, or water; the generation, use, storage, handling, treatment, packaging, transportation, exposure to, and disposal of hazardous and biological materials, including recordkeeping, reporting and registration requirements; and the health and safety of our employees. We may incur significant additional costs beyond those currently contemplated to comply with these regulatory requirements. Further, if we fail to comply with these requirements we may be exposed to fines, penalties and/or interruptions in our operations that could have a material adverse effect on our business, operating results, and financial condition. Certain environmental laws may impose strict, joint and several liability for costs required to clean up and restore sites where hazardous substances have been disposed or otherwise released into the environment, even under circumstances where the hazardous substances were released by prior owners or operators, or the activities conducted and from which a release emanated complied with applicable law. Please see "*We could incur significant costs related to environmental matters, including from government regulation, private litigation, and existing conditions at some of our properties*" below for more detail.

Further, existing regulations, particularly in the environmental area, could be revised or reinterpreted, or new laws and regulations could be adopted or become applicable to us or our facilities and future changes in environmental laws and regulations could occur, including potential regulatory and enforcement developments related to air emissions, any of which could result in significant additional costs. Any of the foregoing could have a material adverse effect on our results of operations and financial condition.

***We could incur significant costs related to environmental matters, including from government regulation, private litigation, and existing conditions at some of our properties.***

We may face costs or obligations related to environmental laws and regulations, including for investigating or cleaning up contamination on our properties, even if the issue was caused by prior owners or operators. U.S. environmental laws, like

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

Comprehensive Environmental Response, Compensation, and Liability Act of 1980, can hold current or past property owners liable for contamination, regardless of fault, and these costs can be significant.

That said, we typically conduct environmental assessments on our project sites, and to date, we have not identified any material issues. Most of our sites have historically been farmland or similar low-risk uses. While these assessments do not include full subsurface testing or asbestos surveys, no significant concerns have been found.

We may also be subject to permitting requirements, including for air quality when installing backup diesel generators, or for water usage in certain markets. Climate-related risks—such as droughts, flooding, or regulations around energy efficiency—may increase over time and could affect data center development or operations. However, at present, we have not encountered any significant environmental obstacles.

***Provisions in our Articles (as defined below), our Bylaws (as defined below), and Nevada law may discourage a takeover attempt even if a takeover might be beneficial to our stockholders.***

Provisions contained in our Articles of Incorporation (as amended, the "Articles") and our Bylaws (the "Bylaws") could make it more difficult for a third party to acquire us if we have become a publicly traded company. Provisions of our Articles and Bylaws impose various procedural and other requirements, which could make it more difficult for stockholders to effect certain corporate actions. For example, our Articles authorize our Board to determine the rights, preferences, privileges, and restrictions of unissued series of preferred stock without any vote or action by our stockholders. Thus, our Board can authorize and issue shares of preferred stock with voting or conversion rights that could adversely affect the voting or other rights of holders of our other series of capital stock. These rights may have the effect of delaying or deterring a change of control of our company. Additionally, our Bylaws establish limitations on the removal of directors and on the ability of our stockholders to call special meetings.

For a more complete understanding of these provisions, please refer to the Nevada Revised Statutes ("NRS") and our Articles and Bylaws filed with the SEC. Though we are not currently, in the future we may become subject to Nevada's control share law. A corporation is subject to Nevada's control share law if it has more than 200 stockholders, at least 100 of whom are stockholders of record and residents of Nevada, and it does business in Nevada or through an affiliated corporation. The law focuses on the acquisition of a "controlling interest" which means the ownership of outstanding voting shares sufficient, but for the control share law, to enable the acquiring person to exercise the following proportions of the voting power of the corporation in the election of directors: (i) one-fifth or more but less than one-third; (ii) one-third or more but less than a majority; or (iii) a majority or more. The ability to exercise such voting power may be direct or indirect, as well as individual or in association with others.

The effect of the control share law is that the acquiring person, and those acting in association with it, obtains only such voting rights in the control shares as are conferred by a resolution of the stockholders of the corporation, approved at a special or annual meeting of stockholders. The control share law contemplates that voting rights will be considered only once by the other stockholders. Thus, there is no authority to strip voting rights from the control shares of an acquiring person once those rights have been approved. If the stockholders do not grant voting rights to the control shares acquired by an acquiring person, those shares do not become permanent non-voting shares. The acquiring person is free to sell its shares to others. If the buyers of those shares themselves do not acquire a controlling interest, their shares do not become governed by the control share law. If control shares are accorded full voting rights and the acquiring person has acquired control shares with a majority or more of the voting power, any stockholder of record, other than an acquiring person, who has not voted in favor of approval of voting rights is entitled to demand fair value for the redemption of such stockholder's shares. Nevada's control share law may have the effect of discouraging takeovers of the corporation.

In addition to the control share law, Nevada has a business combination law which prohibits certain business combinations between Nevada corporations and "interested stockholders" for two years after the "interested stockholder" first becomes an "interested stockholder," unless our Board approves the combination in advance or thereafter by both the Board and 60% of the disinterested stockholders. For purposes of Nevada law, an "interested stockholder" is any person who is (i) the beneficial owner, directly or indirectly, of ten percent or more of the voting power of the outstanding voting shares of the corporation, or (ii) an affiliate or associate of the corporation and at any time within the two previous years was the beneficial owner, directly or indirectly, of ten percent or more of the voting power of the then outstanding shares of the corporation. The definition of the term "business combination" is sufficiently broad to cover virtually any kind of transaction that would allow a potential acquirer to use the corporation's assets to finance the acquisition or otherwise to benefit its own interests rather than the interests of the corporation and its other stockholders. The effect of Nevada's

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

business combination law is to potentially discourage parties interested in taking control of us from doing so if it cannot obtain the approval of our Board.

**General Risk Factors**

***We may become subject to claims of infringement or misappropriation of the intellectual property rights of others, which could prohibit us from selling our products, require us to obtain licenses from third parties or to develop non-infringing alternatives, and subject us to substantial monetary damages and injunctive relief.***

While we believe our current offerings—including Bitcoin hosting, renewable energy curtailment, and demand response services—do not infringe on others' intellectual property, there is a risk that third parties could claim otherwise. For example, we may receive claims alleging that our services infringe on existing or future patents, including in areas where patent applications may still be pending and not yet publicly known.

Defending against such claims could result in legal costs or require us to modify our offerings or obtain licenses, which may not always be feasible or cost-effective. Although we believe this risk is currently low, any disputes could potentially impact our operations or financial condition if they were to arise.

***If we are unable to protect our information systems against service interruption or failure, misappropriation of data or breaches of security, our operations could be disrupted, we could be subject to costly government enforcement actions and private litigation and our reputation may be damaged.***

We rely heavily on complex information systems—both internal and from third-party providers—to run our operations, manage data, and support our customers and employees. These systems store sensitive information, including personal and financial data, and are critical to our day-to-day activities.

Our systems face constant threats, including hacking, phishing, malware, ransomware, and other cyberattacks, as well as risks from human error, software bugs, and system failures. Some threats may come from sophisticated or state-sponsored actors and may not be detected until after they cause harm. Third-party vendors who handle data or support our systems may also introduce risk if they fail to follow proper security practices.

A security breach or system failure could lead to loss or theft of data, service disruptions, reputational damage, regulatory penalties, legal liability, and costly repairs. It could also result in the loss of customers or increased security and insurance expenses. Even with insurance coverage, the financial and reputational impact of a significant cybersecurity incident could materially affect our business and financial results.

***Our risk management process may not identify all risks that we are subject to and will not eliminate all risk.***

Our Enterprise Risk Management ("ERM") process seeks to identify and address significant risks. Our ERM process uses the most recent integrated risk framework in *Internal Control - Integrated Framework (2013)* issued by the Committee of Sponsoring Organizations of the Treadway Commission to assess, manage, and monitor risks. We believe that risk-taking is an inherent aspect of the pursuit of our growth and performance strategy. Our goals are to proactively manage risks in a structured approach in conjunction with strategic planning, with the intent to preserve and enhance shareowner value, and to manage prudently, rather than wholly avoiding, risks. We can mitigate risks and their impact on the Company, however, only to a limited extent, and no ERM process can identify all risks that we may face. Therefore, there may be risks that we are currently unaware of, that may develop in the future or that we currently consider immaterial. Further, our management of risks may prove inadequate. The emergence of risks of which we were unaware or are unable to manage could have a material adverse effect on our business, financial condition, results of operations and prospects,

***Our officers and directors are indemnified against certain conduct that may prove costly to defend.***

Our Articles and Bylaws generally provide broad indemnification to our officers and directors against judgments, fines, amounts paid in settlement and expenses, including attorneys' fees actually incurred in connection with most actions or proceedings to which they are or are threatened to be made a party that relates to their service as an officer or director, except as limited as set forth therein. We are also obligated to advance expenses as they are incurred by a director or officer in defending an action or proceeding prior to final disposition upon receipt of an undertaking by the applicable person to repay such advanced amount if the advancement is ultimately found to not be permitted by law or otherwise.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

In addition, the NRS provides that no director or officer is individually liable for damages as a result of an act or failure to act in his or her capacity as a director or officer except if (i) the presumption that such director or officer acted in good faith, on an informed basis and with a view to the interests of the Company is rebutted, and (ii) it is proven that such director's or officer's act or failure to act constituted a breach of his or her fiduciary duties as a director or officer, and such breach involved intentional misconduct, fraud or a knowing violation of law. Consequently, subject to the applicable provisions of the NRS and to certain limited exceptions in the Articles and Bylaws, the Company's officers and directors will not be liable to the Company or to its stockholders for monetary damages resulting from their conduct as an officer or director. As a result, we may have to spend significant resources indemnifying our officers and directors or paying for damages caused by their conduct.

***We incur significant costs as a result of operating as a public company.***

As a public company, we incur significant legal, accounting, and other expenses. For example, we are subject to the information and reporting requirements of the Securities Act of 1933, as amended (the "Securities Act"), the Exchange Act and other federal securities laws, rules and regulations related thereto, including compliance with the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act"), and the Dodd-Frank Wall Street Reform and Consumer Protection Act. In addition, the Nasdaq listing requirements and other applicable securities rules and regulations impose various requirements on public companies. Our management and other personnel are required to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations significantly increase our legal and financial compliance costs and make some activities more time-consuming and costly. Among other things, we are required to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• maintain and evaluate a system of internal controls over financial reporting in compliance with the requirements of Section 404(a) of the Sarbanes-Oxley Act and the related rules and regulations of the SEC and the Public Company Accounting Oversight Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• maintain policies relating to disclosure controls and procedures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• prepare and distribute periodic reports in compliance with our obligations under federal securities laws; institute a more comprehensive compliance function, including with respect to corporate governance; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• involve, to a greater degree, our outside legal counsel, and accountants in the above activities.

The costs of preparing and filing annual and quarterly reports, proxy statements and other information with the SEC and furnishing audited reports to stockholders is expensive and compliance with these rules and regulations involves a material increase in regulatory, legal, and accounting expenses and the attention of our board of directors and management. In addition, being a public company makes it more expensive for us to obtain director and officer liability insurance. In the future, we may be required to accept reduced coverage or incur substantially higher costs to obtain this coverage. These factors could also make it more difficult for us to attract and retain qualified executives and members of our board of directors. Furthermore, if we are unable to satisfy our obligations as a public company, we could be subject to fines, sanctions and other regulatory action and potentially civil litigation

***Certain natural disasters or other external events, including climate change or mechanical failures, could harm our business, financial condition, results of operations, cash flows, and prospects.***

As with any business, we could experience disruptions due to mechanical failure, human error, physical or electronic security breaches, war, terrorism, fire, earthquake, pandemics, hurricane, flood, and other natural disasters, sabotage, and vandalism. Our systems may be susceptible to damage, interference, or interruption from modifications or upgrades, power loss, telecommunications failures, computer viruses, ransomware attacks, computer denial of service attacks, phishing schemes, or other attempts to harm or access our systems. Such disruptions could materially and adversely affect our business and our financial condition, operating results, cash flows, and prospects.

***We may become involved in litigation arising in the ordinary course of our business that may materially adversely affect us.***

From time to time, we may become involved in various legal proceedings relating to matters incidental to the ordinary course of our business, including intellectual property, commercial, product liability, employment, class action, whistleblower and other litigation and claims, and governmental and other regulatory investigations and proceedings. Attending to such matters can be time-consuming, divert management's attention and resources, cause us to incur

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

significant expenses or liability or require us to change our business practices. Because of the potential risks, expenses, and uncertainties of litigation, we may, from time to time, settle disputes, even where we believe that we have meritorious claims or defenses, and we cannot assure you that the results of any of these actions will not have a material adverse effect on our business. Adverse outcomes in any current or future proceedings that we are involved in or claims against us could result in significant liabilities, monetary damages, fines, or injunctive relief, which may materially impact our financial condition, results of operations, or cash flows. Additionally, the uncertainty surrounding litigation and the potential for adverse publicity related to such matters could harm our reputation and brand image, affecting customer confidence and investor perception.

***If we fail to maintain effective internal controls, we may not be able to report financial results accurately or on a timely basis, or to detect fraud, which could have a material adverse effect on our business or share price.***

As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in those controls. A material weakness is defined as a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented or detected and corrected on a timely basis.

Our management evaluated the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15 and 15d-15(e) under the Exchange Act, as of December 31, 2025. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were not effective at a reasonable assurance level as of December 31, 2025. See "Item 9A Controls and Procedures."

Effective internal controls are necessary for us to provide reasonable assurance with respect to our financial reports and to effectively prevent financial fraud. Pursuant to the Sarbanes-Oxley Act, we are required to periodically evaluate the effectiveness of the design and operation of our internal controls. Internal controls over financial reporting may not prevent or detect misstatements because of inherent limitations, including the possibility of human error or collusion, the circumvention or overriding of controls, or fraud. If we fail to maintain an effective system of internal controls, our business and operating results could be harmed, and we could fail to meet our reporting obligations, which could have a material adverse effect on our business and our share price. Additionally, for as long as we are a "smaller reporting company" under the U.S. securities laws, our independent registered public accounting firm will not be required to attest to the effectiveness of our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act. An independent assessment of the effectiveness of internal control over financial reporting could detect problems that management's assessment might not. Undetected material weaknesses in our internal control over financial reporting could lead to further financial statement restatements and require us to incur the expense of remediation.

If we fail to maintain proper disclosure controls and procedures or have additional material weaknesses in our internal control over financial reporting, we may be unable to accurately report our financial results or report them within the timeframes required by law or any stock exchange regulations, and we could lose investor confidence in the accuracy and completeness of our financial reports, which would cause the price of our common stock to decline. Failure to maintain effective internal control over financial reporting also could potentially subject us to sanctions or investigations by the SEC or other regulatory authorities or stockholder lawsuits, which could require additional financial and management resources.

***If our estimates or judgments relating to our critical accounting policies are based on assumptions that change or prove to be incorrect, our results of operations could fall below the expectations of investors, resulting in a decline in the market price of our common stock.***

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("US GAAP") requires management to make estimates and assumptions that affect the amounts reported in our financial statements. Significant assumptions and estimates used in preparing our financial statements include those related to assets, liabilities, revenue, expenses, and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets, liabilities, equity, revenue, and expenses that are not readily apparent from other sources. Our results of operations may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our results of operations to fall below the expectations of investors, resulting in a decline in the market price of our common stock.

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

***Public health crises, such as pandemics, epidemics, or widespread outbreaks of infectious disease, have had, and could in the future have, an adverse effect on our business, financial condition, and results of operations.***

The occurrence of pandemics, epidemics, or widespread outbreaks of infectious diseases, as well as the imposition of related public health measures and travel and business restrictions or other actions that may be taken by governmental authorities in an effort to contain such pandemics, epidemics, or outbreaks, have had, and could in the future have, a material adverse effect on our business. Future pandemics and similar events could materially increase our costs, severely negatively impact business development, net income, and other results of operations, and impact our liquidity position. The duration of any such impacts cannot be predicted, and such impacts may also have the effect of heightening many of the other material risks we face.

***Changes in accounting rules and regulations, or interpretations thereof, could result in unfavorable accounting charges or require us to change our compensation policies.***

Accounting methods and policies for companies such as ours, including policies governing revenue recognition, leases, research and development and related expenses, and accounting for stock-based compensation, are subject to review, interpretation and guidance from our auditors and relevant accounting authorities, including the SEC. Changes to accounting methods or policies, or interpretations thereof, may require us to reclassify, restate or otherwise change or revise our historical financial statements, including those contained in this Annual Report.

**Risks Related to Our Securities**

***The market price of our securities are likely to be volatile, which may cause investment losses for our shareholders.***

The market price of our securities has been and is likely to continue to be volatile, and investors in our securities may experience a decrease, which could be substantial, in the value of their securities or the loss of their entire investment in the Company for a number of reasons, including reasons unrelated to our operating performance or prospects. The market price of our securities could be subject to wide fluctuations in response to a broad and diverse range of factors, including those described elsewhere in this "Risk Factors" section as well as the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• announcements by us regarding liquidity, significant acquisitions, equity investments and divestitures, addition or loss of significant customers and contracts, capital expenditure commitments and litigation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our issuance of securities or debt, particularly if in connection with acquisition activities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the sale of a significant number of shares of our common stock by shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• recent changes in financial condition or results of operations, such as in earnings, revenues, or other measure of company value;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• general market and economic conditions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• announcements of technological innovations or new product introductions by us or our competitors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Further, broad market and industry factors may have a material adverse effect on the market price of our securities regardless of our actual operating performance.

In addition, stock markets have experienced in the past and may in the future experience a high level of price and volume volatility, and the market prices of equity securities of many companies have experienced in the past and may in the future experience wide price fluctuations not necessarily related to the operating performance of such companies. These broad market fluctuations may adversely affect the market price of our securities.

We have issued, and may continue to issue, new shares of our common stock, which has a dilutive effect on existing stockholders.

In 2025, we have primarily financed our strategic growth through at-the-market ("ATM") offerings and other issuances of our common stock. Our ATM programs allow us to raise capital as needed by selling newly issued shares into the existing trading market at prevailing market prices. We expect to continue using ATM offerings and other equity issuances to fund

development plans, support capital-intensive expansion initiatives, and pursue strategic growth opportunities. However, the issuance of additional shares of our common stock dilutes the ownership interests of existing stockholders, and future equity sales could further dilute existing holdings and reduce the market price of our common stock. Any such dilution may adversely affect the value of an investment in our securities.

Finally, our relatively small public float and daily trading volume have in the past caused, and may in the future result in, significant volatility in the price of our securities. As of December 31, 2025, we had approximately 75,063,284 shares of our common stock outstanding held by non-affiliates and 3,239,854 shares of our 9.0% Series A Cumulative Perpetual Preferred Stock, par value $0.001 per share (the "Series A Preferred Stock"), outstanding held by non-affiliates. Our daily trading volume for the year ended December 31, 2025, averaged approximately 5,166,232 shares of common stock and 18,012 shares of Series A Preferred Stock.

***Because there has been limited precedent set for financial accounting of Bitcoin and other cryptocurrency assets, the determination that we have made for how to account for cryptocurrency assets transactions may be subject to change.***

Because there has been limited precedent set for the financial accounting of cryptocurrencies and related revenue recognition and no official guidance has yet been provided by the FASB or the SEC, it is unclear how companies may in the future be required to account for cryptocurrency transactions and assets and related revenue recognition. A change in regulatory or financial accounting standards could result in the necessity to change our accounting methods and restate our financial statements. Such a restatement could adversely affect the accounting for our newly mined cryptocurrency rewards and more generally negatively impact our business, prospects, financial condition, and results of operations. Such circumstances would have a material adverse effect on our ability to continue as a going concern or to pursue our new strategy at all, which would have a material adverse effect on our business, operations and prospects, as well as potentially on the value of any cryptocurrencies we hold or expect to acquire for our own account, and harm our investors

***If we are not able to comply with the applicable continued listing requirements or standards of Nasdaq, Nasdaq could delist our common stock or Series A Preferred Stock or broker-dealers may be discouraged from effecting transactions in shares of our securities.***

Our common stock has been listed on Nasdaq since March 2020, and our Series A Preferred Stock since August 2021. To maintain these listings, we must continue to meet Nasdaq's financial and corporate governance standards, including requirements for stock price, stockholders' equity, and board independence. While we are currently in compliance, our share price has previously fallen below Nasdaq's minimum, and there is no guarantee we will continue to meet all listing requirements. On May 8, 2025, we received notice from Nasdaq indicating that we were not in compliance with the requirement to maintain a minimum bid price of $1.00 per share for continued listing on Nasdaq (the "minimum closing bid price requirement"). We were provided an initial compliance period of 180 calendar days from the date of the notice, or until November 4, 2025, to regain compliance with the minimum closing bid price requirement, pursuant to Nasdaq Rule 5810(c)(3)(A). On October 3, 2025, we received formal written notice from Nasdaq indicating that we had regained compliance with the minimum closing bid price requirement and that this matter is now closed.

If we are unable to maintain our Nasdaq listings, our securities may be delisted and quoted on over-the-counter (OTC) markets instead. This would likely reduce the liquidity, market price, and visibility of our stock, and could make it more difficult for investors to sell their shares.

Delisting may also limit our ability to raise capital or use our stock as consideration for acquisitions. In addition, if our common stock trades below $5.00 per share and is no longer listed on a national exchange, it could be classified as a "penny stock." This would subject trading in our stock to additional regulatory requirements, which could discourage broker-dealers from making a market in our shares and make it harder for investors to buy or sell our stock.

***The rights of holders of our Series A Preferred Stock and Series B Preferred Stock (as defined below) rank senior to the rights of the holders of our common stock.***

The rights of the holders of shares of our Series A Preferred Stock and Series B Convertible Preferred Stock, par value $0.001 per share (the "Series B Preferred Stock" together with the Series A Preferred Stock, the "Preferred Stock"), while such shares remain outstanding, rank senior to the rights of the holders of shares of our common stock as to dividends and payments upon liquidation, dissolution or winding up of our affairs. Upon liquidation, dissolution or winding up of our affairs, the holders of shares of our Series A Preferred Stock are entitled to receive a liquidation preference of the stated value per share of $25 and the holders of shares of our Series B Preferred Stock are entitled to receive a liquidation preference of the stated value per share of $100, plus all accrued but unpaid dividends, prior and in preference to any

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

distribution to the holders of shares of our common stock or any other class of our equity securities junior to the Preferred Stock. In addition, the holders of the Series A Preferred Stock are entitled to receive, when, as and if declared by the board of directors, cumulative cash dividends at the annual rate of 9.0% of the $25.00 liquidation preference per year. Our holders of Series B Preferred Stock are entitled to receive an annual 10% dividend, which may be paid in cash or stock at our discretion at the earlier of (i) the date the Series B Preferred Stock is converted, or (ii) the Series B Dividend Termination Date (as defined in the Certificate of Designations of Preferences, Rights and Limitations for the Series B Preferred Stock).

These dividend payment obligations could impact our liquidity and reduce the amount of cash available to us for our working capital needs, capital expenditures, funding growth opportunities, acquisitions, and other general corporate purposes. Our obligations to the holders of Preferred Stock could also limit our ability to obtain additional financing or increase our borrowing costs, which could have an adverse effect on our financial condition. The preferential rights could also result in divergent interests between the holders of Preferred Stock and holders of our common stock.

***We do not anticipate paying dividends on our common stock, and investors may lose the entire amount of their investment.***

Cash dividends have never been declared or paid on our common stock, and we do not anticipate such a declaration or payment for the foreseeable future. Any future determination about the payment of dividends will be made at the discretion of our board of directors and will depend upon our earnings, if any, capital requirements, operating and financial conditions, contractual restrictions, including any loan or debt financing agreements, and on such other factors as our board of directors deems relevant. In addition, we may enter into agreements in the future that could contain restrictions on payments of cash dividends. We expect to use future earnings, if any, to fund business growth. Therefore, stockholders will not receive any funds absent a sale of their shares of our common stock. If we do not pay dividends, our common stock may be less valuable because a return on your investment will only occur if our stock price appreciates. We cannot assure stockholders of a positive return on their investment when they sell their shares of our common stock, nor can we assure that stockholders will not lose the entire amount of their investment.

***If securities or industry analysts do not publish research or reports about our business, or if they issue an adverse or misleading opinion regarding our stock, our stock price and trading volume could decline.***

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. We do not currently have and may never obtain research coverage by securities and industry analysts. We cannot assure you that brokerage firms will provide analyst coverage of our company in the future or continue such coverage if started. In addition, investment banks may be less likely to agree to underwrite secondary offerings on our behalf than they might if we became a public reporting company by means of an underwritten initial public offering, because they may be less familiar with our company as a result of more limited coverage by analysts and the media, which could harm our ability to raise additional funding in the future. The failure to receive research coverage or support in the market for shares of our common stock will have an adverse effect on our ability to develop a liquid market for our common stock, which will negatively impact the trading price of our common stock.

In the event we obtain securities or industry analyst coverage, if any of the analysts who cover us issue an adverse or misleading opinion regarding us, or if our operating results fail to meet the expectations of analysts, our stock price would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

**Risks Related to the SEPA**

***Substantial blocks of our common stock may be sold into the market as a result of our being party to the SEPA and you may experience immediate and substantial dilution in the net tangible book value per share of our common stock.***

The price of our common stock could decline if there are substantial sales of shares of our common stock, if there is a large number of shares of our common stock available for sale, or if there is the perception that these sales could occur.

Any issuances of shares of our common stock pursuant to the terms of the Standby Equity Purchase Agreement, dated August 12, 2024 ("SEPA"), between the Company and YA II PN, Ltd. ("YA"), will dilute the percentage ownership of stockholders and may dilute the per share projected earnings (if any) or book value of our common stock. Sales of a substantial number of shares of our common stock in the public market or other issuances of shares of our common stock,

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

or the perception that these sales or issuances could occur, could cause the market price of our common stock to decline and may make it more difficult for you to sell your shares at a time and price that you deem appropriate. Additionally, the offering price per share of our common stock under the SEPA may or may not exceed the net tangible book value per share of our common stock outstanding prior to the offering under the SEPA.

***It is not possible to predict the actual number of shares we will sell under the SEPA, or the actual gross proceeds resulting from those sales.***

The SEPA provides that, during the term of the agreement, and subject to issuance and effective registration of the shares issued thereunder and certain obligations and limitations, we may, at our discretion, from time to time direct YA to purchase our shares of common stock from us in one or more purchases under the agreement, for a maximum aggregate purchase price of up to $25 million. The purchase price per share to be paid by YA for the shares of common stock that we may elect to sell to YA under the SEPA, if any, will fluctuate based on the market prices of our shares of common stock at the time we elect to sell shares to YA pursuant to the SEPA. Therefore, it is not possible for us to predict the number of shares of common stock that we will sell to YA under the SEPA, the purchase price per share that YA will pay for shares purchased from us under the SEPA, or the aggregate gross proceeds that we will receive from those purchases by YA under the SEPA.

Although we may, at our discretion, from time to time direct YA to purchase our shares of common stock from us in one or more purchases under the SEPA, we shall not effect any sales under the SEPA to the extent that after giving effect to such sale YA would beneficially own more than 9.99% of the Company's outstanding common stock at the time of such issuance. Thus, the Company may not have access to the right to sell the full $25 million of shares of common stock to YA.

**Item 1B: Unresolved Staff Comments**

Not applicable.

**Item 1C: Cybersecurity**

We, like other companies in our industry, face several cybersecurity risks in connection with our business. Our business strategy, results of operations, and financial condition have not, to date, been affected by risks from cybersecurity threats. During the reporting period, we have not experienced any material cyber incidents, nor have we experienced a series of immaterial incidents, which would require disclosure. We proactively approach cybersecurity through a systemized thorough process established by our internal Management and IT teams as well as external IT providers.

These processes are specifically designed to adapt to the evolving cybersecurity environment, enabling us to respond swiftly and effectively to new and emerging threats. Our cybersecurity initiative incorporates elements from multiple industry benchmarks, including frameworks from the National Institute of Standards and Technology and the Center for Internet Security.

We regularly assess the threat landscape and take a holistic view of cybersecurity risks with a layered cybersecurity strategy based on prevention, detection, and mitigation. Our internal IT team works closely with our external IT management provider to comprehensively evaluate cybersecurity risks. They focus on monitoring, identifying, and addressing significant cybersecurity issues in real-time by employing advanced software monitoring platforms for effective mitigation and management. In addition, we have several avenues to gather risk intelligence and potential threats identified by various services and capabilities to adjust our security strategy.

We also have Company-wide policies and procedures concerning cybersecurity and technology standards, including a Resource and Data Recovery policy. In addition, we have other policies related to endpoint and network protection, encryption standards, malware/ransomware protection, multi-factor authentication, operational security, and confidential information. These policies go through an internal review process and are approved by appropriate members of management.

We have invested in IT security, encompassing various strategies such as enhanced end-user training, implementing layered defense systems, identifying and safeguarding critical assets, bolstering monitoring and alert capabilities, and consulting with expert advisors. On the management front, our IT security team diligently oversees alert systems and routinely convenes to evaluate current threat levels, analyze trends, and strategize effective remediation methods.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

In addition to assessing our own cybersecurity preparedness, we also consider and evaluate cybersecurity risks associated with the use of third-party vendors and service providers. The internal business owners of the hosted applications are required to review user access at least annually and provide a System and Organization Controls ("SOC") 1 or SOC 2 report from the vendor. If a third-party vendor is unable to provide a SOC 1 or SOC 2 report, we take additional steps to assess their cybersecurity preparedness and assess our relationship on that basis.

***Governance***

Under the direction of the Company's VP of Engineering and Director of Information Technology, with oversight from the Board, we maintain a security governance structure to evaluate and address cyber risk. The VP of Engineering and the Director of IT are responsible for developing and implementing our information security program. Our VP of Engineering has over a decade of experience in the Defense sector working directly with technology-driven Operational Security.

The Director of IT regularly oversees the Company's cybersecurity program. This comprehensive review includes examining management's initiatives to identify and detect potential threats, outlining planned responses and recovery strategies for potential incidents, evaluating recent improvements made to the Company's security detection and response capabilities, and assessing management's advancement along the cybersecurity strategic roadmap. The internal IT team also subscribes to various threat intelligence services to evaluate our security strategy or defense mechanism against such threats.

Our board of directors has ultimate oversight of our strategic and business risk management and, as such, has oversight responsibilities for risks and incidents relating to cybersecurity threats, including compliance with disclosure requirements, cooperation with law enforcement, and related effects on financial and other risks. Management is responsible for identifying, assessing, and managing material cybersecurity risks on an ongoing basis, establishing and updating processes to ensure such potential risks are monitored, putting in place appropriate mitigation measures, and will be providing regular reports on cybersecurity trends and risks, and should they arise, any material incidents with our board of directors.

**Item 2: Properties**

We lease approximately 3,478 square feet of office, in Albany, New York, which houses the corporate offices of SHI. The current lease agreement expires on December 31, 2027.

On March 4, 2021, Soluna SW, LLC acquired a 3.2-acre tract of real property located in Murray, Kentucky on which it has built an energy-efficient cryptocurrency mining facility, Project Sophie, that includes 22 buildings for data facility hosting.

On February 24, 2023, Soluna DV Services, LLC entered into a lease agreement for a 33.19-acre tract of land in Silverton, Texas. The agreement has an initial five-year term with the right to extend the term of the agreement for five additional one-year terms. The lease is associated with our Dorothy facilities for the purpose of constructing, installing, operating and maintaining modular data centers.

On April 3, 2025, Soluna KK Energy ServiceCo, LLC entered into a lease agreement for 50 acres of property located in Willacy County, Texas, for the purpose of constructing, installing, operating, and maintaining modular data centers and related facilities for a term of twenty-two years. This leased agreement will be used for Project Kati 1.

On October 1, 2025, Soluna KK Energy ServiceCo, LLC purchased 50 acres of property located in Willacy County, Texas for the purpose of constructing, installing, operating, and maintaining modular data centers and related facilities. This purchase of land will be used for Project Kati 2.

We believe these facilities are generally well-maintained and adequate for the Company's current needs and for expansion, if required. Our business growth, however, is dependent on developing additional properties, and we believe our project pipeline is strong enough to support our current business plan.

**Item 3: Legal Proceedings**

At any point in time, we may be involved in various lawsuits or other legal proceedings. Such lawsuits could arise from the sale of products or services or from other matters relating to our regular business activities, compliance with various governmental regulations and requirements, or other transactions or circumstances.

**PART II**

**Item 5: Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities**

**Market Information**

Our common stock is listed on the Nasdaq Capital Market under the trading symbol "SLNH."

**Holders**

We have one class of common stock, par value $0.001, and are authorized to issue 375,000,000 shares of common stock. Each share of our common stock is entitled to one vote on all matters submitted to shareholders. As of December 31, 2025, there were 102,531,089 shares of common stock issued and outstanding. As of March 9, 2026, there were approximately 123 shareholders of record of our common stock. The number of shareholders of record does not reflect the number of persons whose shares are held in nominee or "street" name accounts through brokers.

**Dividends**

As of December 31, 2025, we had 4,928,545 shares of our Series A Preferred Stock outstanding, which pursuant to the Certificate of Designations, Preferences and Rights of 9.0% Series A Cumulative Perpetual Preferred Stock, of the Company entitle such holders to monthly dividends, when, as and if declared by our board of directors. Our board of directors had not declared any Series A Preferred Stock dividends beginning October 2022 through December 31, 2024, as such the Company has accumulated approximately $18.5 million of dividends in arrears on the Series A Preferred Stock through December 31, 2024, and an additional $11.1 million of dividends in arrears for the year ended December 31, 2025, for a total of approximately $29.6 million.

Our Series B Preferred Stock included a 10% accruing dividend compounded daily for 12 months from the original issue date of July 20, 2022, and annually thereafter, that may be paid in cash or stock at the Company's option at the earlier of (i) the date the Series B Preferred Stock is converted, or (ii) the Series B Dividend Termination Date (as defined in the Certificate of Designation of the Series B Preferred Stock). Effective October 1, 2024, the dividend payment obligation has been modified to be annual. The amendment resulted in annual dividend payments going forward. As a result of the amendment, we would be obligated to make annual dividend payments for the period starting from July 2023 as per the Series B Preferred Consent and Waiver, however, the board of directors has not yet declared any dividends for that period through December 31, 2025. As such, we have accumulated approximately $1.6 million dividends in arrears in relation to the Series B Preferred Stock.

The Company does not intend to pay dividends on our common stock and do not anticipate or contemplate paying cash dividends on our common stock in the foreseeable future. We currently intend to use all available funds to develop our business. We can give no assurance that we will ever have excess funds available to pay dividends. Any future determination as to the payment of dividends will depend upon critical requirements and limitations imposed by our credit agreements, if any, and such other factors as our board of directors may consider.

**Item 6: [Reserved].**

**Item 7: Management's Discussion and Analysis of Financial Condition and Results of Operations**

*The following discussion of our financial condition and results of operations should be read in conjunction with our Consolidated Financial Statements and the related notes included elsewhere in this Annual Report. This discussion contains forward-looking statements, which involve risk and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of certain factors, including those discussed in Item 1A: "Risk Factors" and elsewhere in this Annual Report.*

**Recent Developments**

**Appointment of Chief Financial Officer**

On January 19, 2026, Michael Picchi was appointed as the CFO and Treasurer of the Company, effective April 1, 2026 (the "Effective Date"). Mr. Picchi began his employment with the Company on March 2, 2026, in the role of Head of Finance.

In conjunction with the appointment of a new CFO and Treasurer, the Company will accept David Michaels' resignation from his position as interim CFO and Treasurer of the Company, effective immediately upon the effectiveness of the appointment of a new CFO and Treasurer.

**2026 SEPA**

On March 24, 2026, we entered into a Standby Equity Purchase Agreement (the "2026 SEPA") with YA II PN, LTD., a Cayman Islands exempt limited company ("YA"). In accordance with the terms of the SEPA, YA has agreed to purchase up to an aggregate of $250.0 million of shares of common stock (the "2026 SEPA Shares") from time to time subject to the limits and the conditions of the 2026 SEPA. Pursuant to the 2026 SEPA, we issued to YA a commitment fee of $250 thousand of shares of common stock (the "Commitment Shares").

<u>Project Specific Developments</u>

**Project Kati 1**

In February 2026, we received approval from the Electric Reliability Council of Texas ("ERCOT") to commence the initial energization and phased commissioning of Project Kati 1. This milestone represents the transition of the project from the development phase to operational status. The Company expects to begin recognizing hosting and/or mining revenue from this facility as capacity is ramped up throughout the first half of 2026. Project Kati 1 is the Company's 83 MW wind-powered data center campus located in South Texas, specifically designed for high-density Bitcoin mining operations. The site's energization is structured in two primary blocks: Kati 1A (48 MW) and Kati 1B (35 MW). Both blocks are being deployed utilizing a three-phase commissioning approach, with full energization of the 83 MW campus expected to be completed during 2026. Kati 1B includes a 12 MW deployment with Cormint Data Systems ("Cormint"), where Cormint will design, procure, and deliver eight modular data center units to enable efficient deployment by minimizing on-site labor and accelerating energization timelines. Powered entirely by the Las Majadas wind energy project, Project Kati represents one of Soluna's largest sites to date and is designed to scale efficiently to support large industrial compute workloads.

**Project Kati 2**

We have signed a Memorandum of Understanding ("MOU") with Metrobloks, a data center developer and operator focused on AI-ready infrastructure, to enter into a co-development partnership to build Project Kati 2. The initial development will be a 100+ MW Critical IT ("CIT") AI and HPC data center at Soluna's Project Kati 2 campus in Willacy County, Texas. This is expected to be the first phase of a larger campus, with an expansion roadmap supporting more than 300 MW of total CIT capacity.

**Project Grace**

We have entered a MOU with Siemens, a leading technology company in electrification, automation and digitalization. The project will deploy and validate a behind-the-meter power-and-controls approach to manage rapid, GPU-driven swings in power demand when running AI and high-performance computing workloads directly on renewable energy. The 2 MW pilot, expected to be deployed at Soluna's Project Grace site in Texas, will integrate Siemens' electrical infrastructure, controls, and monitoring through a structured commissioning process to document performance under fast load steps and variable compute demand, creating a repeatable blueprint for future behind-the-meter AI deployments at renewable generation sites.

***Cryptocurrency Mining Revenue***: Cryptocurrency mining revenue decreased during the year ended December 31, 2025, compared to 2024, primarily driven by the April 2024 halving event which reduced block rewards by 50%. Average Hashprice declined year-over-year by 21.5% resulting in lower revenues. We earned 113.2 Bitcoins in 2025 compared to 274 in 2024. Average monthly hashrate was lower in 2025 by approximately 10.7% impacting revenue by $1.8 million versus prior year, the decrease in earned Bitcoin was driven by the halving event. The market price impact resulted in a $3.8 million revenue unfavorable versus prior year.

***Data Hosting Revenue***: Hosting revenue decreased for the year ended December 31, 2025, compared to 2024, driven by two primary factors. First, the April 2024 Bitcoin Halving reduced the effective dollar value per Petahash ("PH") per day, lowering yields across both fixed-fee and profit-sharing contracts. Second, the exit of a major 20 MW customer in December 2024 resulted in a shift in our contract mix. While this capacity was fully backfilled by March 2025, the new customers were onboarded under a profit-sharing structure which, while providing higher upside potential, resulted in a lower baseline revenue yield compared to the prior fixed-fee model. These declines were partially offset by the phased energization of the D2 facility, which began contributing to revenue in the third quarter of 2025.

***Demand Response Service***: Demand response service revenue decreased for the year ended December 31, 2025, compared to 2024, reflecting both unfavorable market conditions and operational constraints. Lower average ERCOT clearing prices per MW reduced the overall economic incentive per event. Operationally, our program participation was limited by planned outages at the Dorothy site related to the Project Dorothy 2 ("D2") substation interconnection. These factors collectively resulted in lower capacity bids and decreased total revenue from curtailment services.

***Cost of Cryptocurrency Mining Revenue, exclusive of depreciation****:* Cost of cryptocurrency mining revenue includes direct utility costs, site overhead expenses, and overhead costs that relate to the operations of our cryptocurrency mining facilities in Kentucky and Texas.

Cost of cryptocurrency mining revenue decreased slightly for the year ended December 31, 2025, compared to 2024. This variance was primarily driven by lower electricity consumption and associated operating expenses, reflecting a marginal reduction in total power utilization during the period.

***Cost of Data Hosting Revenue, exclusive of depreciation:*** Cost of data hosting revenue includes utility charges, site overhead expenses, and other charges.

Cost of data hosting revenue decreased for the year ended December 31, 2025, compared to 2024. This decline was primarily driven by a transition in the customer contract mix, as the Company moved from fixed-rate volume arrangements to electricity pass-through contracts. This shift reduced the Company's direct exposure to power costs for those hosting arrangements. The decrease was partially offset by the phased energization of D2 beginning in the second quarter of 2025, which resulted in higher total megawatt ("MW") capacity and an associated increase in operating expenses during the second half of the year.

***Cost of High-Performance Computing Services:*** Cost of High-Performance Computing Services represents the direct production expenses associated with providing AI and HPC processing capabilities. For the year ended December 31, 2024, this cost totaled approximately $5.7 million, which was related to the agreement executed with HPE effective July 1, 2024, to acquire access to essential datacenter and cloud services necessary for supporting our AI and HPC processes.

Cost of High-Performance Computing Services was not material for 2025 due to the termination of the HPE contract.

***Cost of Data Hosting Revenue- depreciation:*** Cost of data hosting revenue-depreciation increased mainly due to D2 becoming energized during fiscal year 2025.

***General and Administrative Expenses, exclusive of depreciation and amortization:*** General and administrative expenses, exclusive of depreciation and amortization include cash and non-cash compensation, benefits, and related costs in support of our general corporate operations, including general management, finance and accounting, human resources, marketing, information technology, corporate development, and legal services.

.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Stock-based compensation expense increased by $5.2 million to approximately $10.4 million for the year ended December 31, 2025. The growth was primarily driven by $3.7 million in new equity awards granted to directors, officers, and employees during 2025, and a $2.5 million increase attributable to the full-year expense impact of 2024 grants. Additionally, the Company recognized $0.8 million related to modifications of vesting terms for certain grants and a reduction in the estimated forfeiture rate from 10% to 5%. These increases were partially offset by $1.8 million in savings resulting from the forfeiture of unvested awards due to employee departures and the impact of awards that reached full vesting during the prior year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Salaries and benefits expense increased approximately $4.3 million for the year ended December 31, 2025, primarily due to performance-based and year-end bonuses for fiscal year 2025, as well as cost-of-living and merit-based salary adjustments for management and employees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Legal fees increased approximately $1.7 million for the year ended December 31, 2025, primarily due to expenses related to Project Kati structuring costs that were not incurred in the comparable prior-year period, business development of pipeline projects, expenses related to corporate governance and compliance driven by growth in organizational structure and debt, and current year changes in primary counsel.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Professional and consulting fees increased approximately $0.8 million related to increases noted in contracted services, debt consulting charges, and business development costs associated with pipeline growth.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Investor relations expense increased approximately $0.8 million for the year ended December 31, 2025, compared to the same period in 2024, primarily due to an increase in the number and scope of investor outreach and marketing campaigns conducted during the period.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provision for credit losses decreased approximately $0.8 million for the year ended December 31, 2025, as no credit losses were recognized during the current period, compared to the prior year, which included specific loss provisions recorded on outstanding receivables.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• All other fluctuations within general and administrative expenses for the period were not material to the overall results of operations.

***Depreciation and Amortization associated with general and administrative expenses:*** Depreciation and amortization expense was comparable for the year ended December 31, 2025 and the year ended December 31, 2024 in which the balances totaled approximately $9.6 million and $9.6 million, respectively. The balances mainly related to amortization expense related to the strategic pipeline contract that was acquired in October 2021.

***Loss on contract:*** Due to CloudCo's termination of the HPE Agreement on March 24, 2025, and HPE's subsequent termination of the HPE Agreement on March 26, 2025, and the acceleration of the remaining unpaid amounts of the contract in accordance with Section 8(h)(ii) of the HPE Agreement, a Type 1 Subsequent Event for the year ended December 31, 2024, we have recognized a liability for the remainder of the HPE Agreement on the consolidated balance sheet of our subsidiary CloudCo, and corresponding loss on contract on our consolidated income statement, in line with the terms and conditions of the HPE Agreement and relevant accounting standards. CloudCo also recognized a loss on the termination of the HPE Agreement for $28.6 million representing the remaining obligations for the year ended December 31, 2024, and a contract liability in the same amount. In addition, the outstanding balance of the prepaid deposit of $8.6 million was offset to the liability, leaving a net liability balance of $20.0 million as of December 31, 2024, in which another $0.7 million was paid, leaving an outstanding balance of $19.3 million as of December 31, 2025.

***Interest expense:*** Interest expense for the year ended December 31, 2025, was approximately $4.8 million, compared to approximately $2.5 million for the year ended December 31, 2024. This increase is primarily attributable to the new debt facilities entered into during fiscal years 2024 and 2025, including the Green Cloud secured loan and additional secured loan agreements, the Galaxy loan, the Generate loan, and the equipment loan. The expense for the current period also includes the amortization of deferred financing costs associated with these new facilities, partially offset by the full payoff of the Navitas loan and extinguishment of the NYDIG equipment financing. Further details on the components of interest expense are presented in the table below.

***Loss on sale of fixed assets and credit on equipment deposit:*** During the year ended December 31, 2025, we recognized a loss of approximately $1.2 million mainly related to the forfeiture of an equipment credit that had been recorded in prior periods. The credit was restricted for use on future equipment purchases for D2 and Project Kati through September 1, 2025. We did not execute an order prior to the expiration date, and no extension was granted; therefore, the credit was forfeited, and therefore had a loss of approximately $780 thousand. In addition, approximately $371 thousand of miners were disposed of due to aging and replaced with the purchase of new miners for the year ended December 31, 2025. The loss on sale of fixed assets for the year ended December 31, 2024 was not material.

***Other financing expense:*** We incurred approximately $5.9 million in financing expenses for the year ended December 31, 2025, primarily related to consent fees associated with the SEPA, draws under the At the Market Offering Agreement

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

entered into with H.C. Wainwright & Co., LLC (the "ATM Agreement") on April 29, 2025, and transaction costs incurred in connection with the July 2025 financing.

For the year ended December 31, 2024, other financing expense totaled approximately $3.7 million which was comprised primarily of a $1.0 million general release agreement with our former placement agent; approximately $1.9 million in consent fees, waiver fees, and other financing expenses in relation to the SEPA and related consents for the SEPA on October 1, 2024; a conversion debt inducement expense of approximately $388 thousand; and an extension fee expense of approximately $325 thousand.

***Fair value adjustment, net***: For the year ended December 31, 2025, we recognized a fair value adjustment loss of approximately $23.7 million related to the revaluation of the Series A and Series B warrants issued in connection with the July 2025 financing, which were classified as liabilities and exercised during the year ended 2025. The loss also includes a $14.7 million fair value adjustment related to the revaluation of outstanding warrant liabilities throughout 2025. These losses were primarily driven by the increase in the Company's stock price between July and October 2025, which resulted in a higher intrinsic value relative to the warrants' original fair value. Additionally, we incurred an approximate $9.1 million loss representing the excess of the fair value of warrants issued in connection with the July 2025 financing over the related proceeds received, and $0.1 million in fair value adjustments related to timing differences between SEPA draws and share issuances. These losses were partially offset by a gain of approximately $0.2 million from the revaluation of the Generate common warrant during the period.

For the year ended December 31, 2024, we recognized a net fair value adjustment loss of approximately $5.7 million, primarily related to the issuance and repricing of additional warrants with modified exercise features pursuant to the Fourth Amendment Agreement with the Noteholders, dated February 28, 2024 (the "Fourth Amendment"). As a result of these modifications, the warrants were reassessed and classified as warrant liabilities, requiring recurring fair value measurement each reporting period. The initial issuance and repricing resulted in a fair value adjustment loss of approximately $5.9 million, which was partially offset by revaluation gains recognized through May 30, 2024, the date of the Company's Annual Shareholder meeting . Upon shareholder approval, the cap-containment provision was removed, and since all other criteria for equity classification were met, the remaining warrant liability was reclassified to equity. Additionally, the Company recognized a gain on revaluation of approximately $0.3 million related to the Soluna Cloud warrants, which were subsequently written off during the period.

***Gain (loss) on Debt Extinguishment and Revaluation, net***: For the year ended December 31, 2025, we recognized a net gain on extinguishment of debt of approximately $10.7 million. The gain primarily related to the settlement of the NYDIG equipment financing loan and related interest obligations in September 2025, as well as the Assignment and Assumption Agreement for the Additional Notes executed on March 14, 2025. These gains were partially offset by a loss on extinguishment resulting from the satisfaction and redemption of the Project Kati equipment loan through the issuance of Class B Membership Interests in Project Kati, which were valued at approximately three and three-tenth times the original borrowing amount.

For the year ended December 31, 2024, we recognized a net loss on debt extinguishment and revaluation of approximately $1.6 million. On February 28, 2024, we entered into the Fourth Amendment, which reduced the conversion price and resulted in the issuance of new warrants and the repricing of existing warrants with revised exercise features. As a result, the Company recorded a gain on revaluation of convertible notes of approximately $1.3 million during the first quarter of 2024 (as of February 28 and March 31, 2024), primarily driven by changes in conversion assumptions, payout features, annualized volatility, and stock price conditions at the respective valuation dates. A subsequent fair value assessment as of June 30, 2024 resulted in a loss on revaluation of approximately $4.0 million, reflecting changes in conversion and payout assumptions and stock price volatility compared to conversion terms available to noteholders at that date. The convertible notes were remeasured again as of September 30, 2024, resulting in a gain of approximately $2.3 million, primarily due to the decline in the Company's stock price, which offset prior-quarter fair value losses. In the fourth quarter of 2024, we had additional conversions and ultimately fully converted the convertible notes payable creating an additional $247 thousand gain on debt extinguishment. As of December 31, 2024, no convertible notes remain outstanding. In addition to these fair value adjustments, we recognized a loss on debt extinguishment of approximately $1.4 million related to the satisfaction and redemption of the D2 equipment loan through the issuance of Class B Membership Interests in the D2 project, which were valued at approximately three times the original borrowing amount.

***Other (expense) income, net:*** Other expense, net increased by approximately $1.0 million year for the ended December 31, 2025 compared to December 31, 2024. For the year ended December 31, 2025, we incurred a loss compensation cost of approximately $713 thousand in relation to the Las Majadas wind farm due to outages during certain points of the year. For the year ended December 31, 2024, we had other income of approximately $304 thousand related mainly to a gain on

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

settlement of litigation with Atlas Technology Group LLC ("Atlas") of approximately $254 thousand, in addition to some small additional other income items.

***Income Tax Benefit:*** Income tax benefit for the year ended December 31, 2025 was approximately $2.3 million, compared to approximately $2.5 million for the year ended December 31, 2024. The balances were mainly related to deferred tax amortization impact of acquiring an asset in a transaction that is not a business combination when the amount paid exceeds the tax basis on the acquisition date. As such, we are required to adjust the value of the strategic contract pipeline by approximately $10.9 million at inception date (October 29, 2021), which was recorded as a deferred tax liability and this amount will be amortized over the life of the asset. For the years ended December 31, 2025 and 2024, we amortized approximately $2.2 million in each year, respectively.

***Net income attributable to non-controlling interest:*** We incurred a net loss attributable to non-controlling interest for the year ended December 31, 2025 compared to a net income attributable to non-controlling interest for the year ended December 31, 2024. The decrease related mainly due the variances in gross profit related to D1A and D1B noted above mainly due to the halving event in April 2024 and the increase in profit sharing fees for data hosting for the year ended December 31, 2025, which created an approximate $5.7 million variance between periods in non-controlling interest. In addition, we incurred a loss of approximately $1.7 million associated with the satisfaction of equipment loan through membership interest at Project Kati, in addition to Project Kati costs of approximately $2.0 million, in which no revenue had been generated yet for the year ended December 31, 2025, and no comparable costs were noted for the year ended December 31, 2024. The change at D2 was a gain of approximately $873 thousand, due to site energization which began in the second quarter of 2025 in which costs exceeded the revenue by approximately $1.0 million. For the year ended December 31, 2024, D2 had a loss on non-controlling interest due to the satisfaction in an equipment loan creating a loss of approximately $1.4 million and additional costs of $500 thousand.

**Non-GAAP Measures**

To supplement our consolidated financial statements included in this Annual Report presented under U.S. generally accepted accounting principles ("GAAP"), we are presenting certain non-GAAP financial measures. We are providing these non-GAAP financial measures to disclose additional information to facilitate the comparison of past and present operations by providing perspective on results absent one-time or significant non-cash items. We utilize these measures in the business planning process to understand expected operating performance and to evaluate results against those expectations. We believe that these non-GAAP financial measures, when considered together with our GAAP financial results, provide management and investors with an additional understanding of our business operating results regarding factors and trends affecting our business and provide a reasonable basis for comparing our ongoing results of operations.

These non-GAAP financial measures are provided as supplemental measures to our performance measures calculated in accordance with GAAP and therefore, are not intended to be considered in isolation or as a substitute for comparable GAAP measures. Further, these non-GAAP financial measures have no standardized meaning prescribed by GAAP and are not prepared under any comprehensive set of accounting rules or principles. Because of the non-standardized definitions of non-GAAP financial measures, we caution investors that the non-GAAP financial measures as used by us in this Annual Report have limits in their usefulness to investors and may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by other companies. Further, investors should be aware that when evaluating these non-GAAP financial measures, these measures should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. In addition, from time to time in the future there may be items that we may exclude for purposes of our non-GAAP financial measures and we may in the future cease to exclude items that we have historically excluded for purposes of our non-GAAP financial measures. Likewise, we may determine to modify the nature of the adjustments to arrive at our non-GAAP financial measures. Investors should review the non-GAAP reconciliations provided below and not rely on any single financial measure to evaluate our business.

*EBITDA and Adjusted EBITDA*

In addition to financial measures calculated in accordance with GAAP, we also use "EBITDA" and "Adjusted EBITDA." "EBITDA" is defined as earnings before interest, taxes, and depreciation and amortization. "Adjusted EBITDA" is defined as EBITDA adjusted for stock-based compensation costs, loss on sale of fixed assets and credit on deposit, loss on debt extinguishment and revaluation, fair value adjustments, placement agent release expense, loss on contract, provision for credit losses, convertible note inducement expense and impairment on fixed assets. Management believes that EBITDA and Adjusted EBITDA results in a performance measurement that represents a key indicator of our business operations of cryptocurrency mining, hosting customers engaged in cryptocurrency mining, demand service revenue, and high-performance computing services.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

We believe EBITDA and Adjusted EBITDA can be important financial measures because they allow management, investors, and the Board to evaluate and compare our operating results, including our return on capital and operating efficiencies, from period-to-period by making such adjustments. Non-GAAP financial measures are subject to material limitations as they are not in accordance with, or a substitute for, measurements prepared in accordance with GAAP. For example, we expect that stock-based compensation costs, which is excluded from the non-GAAP financial measures, will continue to be a significant recurring expense over the coming years and is an important part of the compensation provided to certain employees, officers, and directors. Similarly, we expect that depreciation and amortization of fixed assets will continue to be a recurring expense over the term of the useful life of the assets.

EBITDA and Adjusted EBITDA are provided in addition to and should not be considered to be substitutes for, or superior to net income, the comparable measure calculated in accordance with GAAP. Further, EBITDA and Adjusted EBITDA should not be considered as alternatives to revenue growth, net income, or any other performance measure calculated in accordance with GAAP, or as alternatives to cash flow from operating activities as a measure of our liquidity. EBITDA and Adjusted EBITDA have limitations as analytical tools, and you should not consider such measures either in isolation or as substitutes for analyzing our results as reported under GAAP.

Reconciliations of EBITDA and Adjusted EBITDA to net loss, the most comparable GAAP financial metric, for historical periods are presented in the table below:

Adjusted EBITDA decreased for the year ended December 31, 2025 compared to December 31, 2024 primarily driven by increases in general and administrative expenses, exclusive of depreciation, stock-based compensation costs, and provision for credit losses of approximately $7.4 million for the comparable periods. The general and administrative expense increase was driven by increases in 2025 salary and bonus expenses of $4.3 million, professional and legal fees of $2.5 million, and investor relations of $0.8 million for the year ended December 31, 2025 compared to the year ended December 31, 2024. We also incurred other financing costs increases of approximately $2.2 million for the year ended December 31, 2025 compared to the year ended December 31, 2024, due to Preferred B holder consent fees for draws under the ATM, the SEPA, and July 2025 financing, in which fees in the prior year were lower for comparable expenses such as SEPA consents and other financing expense items.

In addition, for the year ended December 31, 2025 compared to year ended December 31, 2024 , there was a decrease in revenue of approximately $8.3 million primarily in Cryptocurrency mining and data hosting revenue following the April 2024 Bitcoin halving and a customer ramp-up of 20 MW through the first quarter of 2025, partially offset by approximately $6.1 million decline in cost of revenue, excluding depreciation, largely due to no costs associated with high-performance computing services for 2025.

**Liquidity and Capital Resources**

As of December 31, 2025, we had a consolidated accumulated deficit of approximately $367.7 million and we had positive working capital of approximately $42.9 million. As of December 31, 2025, we had total debt outstanding of approximately $26.8 million as summarized further below in the Debt table. In addition, we had outstanding commitments related to Soluna Digital Inc. ("SDI") of approximately $27.0 million in capital expenditures related to Project Kati. In addition, due to CloudCo's termination of the HPE Agreement on March 24, 2025, and HPE's termination of the HPE Agreement on March 26, 2025, and the acceleration of the remaining unpaid amounts of the contract in accordance with Section 8(h)(ii) of the HPE Agreement, we have recognized a liability for the remainder of the HPE Agreement on the balance sheet of our subsidiary, CloudCo, of approximately $19.3 million. As of December 31, 2025, we had $76.4 million of cash available to fund our operations.

Based on business developments, including changes in production levels, staffing requirements, and network infrastructure improvements, we will require additional capital equipment in the foreseeable future. We are focused on developing and monetizing green cryptocurrency mining facilities, as well as facilities capable of hosting customers engaged in cryptocurrency mining, and data centers to provide specialized AI Cloud and colocation services.

In 2025, we had the following capital raise activities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• At the Market Offering Agreement (the "ATM Agreement") with H.C. Wainwright & Co., LLC ("Wainwright"), as sales agent, pursuant to which we may offer and sell, from time to time, through Wainwright, up to $87.65 million. As of December 31, 2025, we had drawn approximately $34.2 million in net proceeds pursuant to the ATM Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Standby Equity Purchase Agreement (the "SEPA") with YA II PN, LTD., a Cayman Islands exempt limited company ("YA"). In accordance with the terms of the SEPA, YA has agreed to purchase up to $25 million in aggregate gross purchase price of newly issued fully paid shares of our common stock from time to time subject to the limits and the conditions of the SEPA. As of December 31, 2025, approximately $6.2 million has been drawn on the SEPA.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In July 2025, we entered into a securities purchase agreement pursuant to which we received gross proceeds of $5.0 million from a public offering of common stock. In connection with this offering, we issued warrants, and as of December 31, 2025, we received approximately $10.0 million in gross proceeds from the exercise of such warrants.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In December 2025, we entered into a securities purchase agreement to which we received gross proceeds of approximately $32.0 million from a public offering of common stock.

We plan to continue funding operations, including working capital and operating deficits, from operating cash flows and cash flow debt and equity financings, including the ATM Agreement, SEPA, July 2025 financing, December 2025 financing, and others to be closed as needed consistent with management's plans.

The Company is dependent on generating profitable operations in the future and/or obtaining the necessary financing to meet its obligations and repay its liabilities arising from normal business operations when they come due. In the near term, management is evaluating and implementing different strategies to obtain financing to fund the Company's expenses and growth to achieve a level of revenue adequate to support the Company's current cost structure. Financing strategies may include, but are not limited to, stock issuances, project level equity, debt borrowings, partnerships and/or collaborations. If the Company is unable to meet its financial obligations, it could be forced to restructure or refinance, seek additional equity

capital or sell its assets. The Company might then be unable to obtain such financing or capital or sell its assets on satisfactory terms. There can be no assurance that additional financing will be available to the Company when needed or, if available, that it can be obtained on commercially reasonable terms. If the Company is not able to obtain the additional financing on a timely basis, if and when it is needed, it will be forced to delay or scale down some or all of its development activities or perhaps even cease the operation of its business.

**Operating Activities**

Net cash used in operating activities from operations was approximately $9.1 million for the year ended December 31, 2025. We had a net loss of approximately $57.0 million, which was offset by non-cash items of approximately $40.2 million. Non-cash items included approximately $6.9 million of depreciation expense, $9.5 million of amortization expenses, $23.7 million in fair value adjustments mainly related to warrants being exercised, and $10.6 million of stock compensation expenses. These non-cash items were offset with a deferred tax benefit of $2.3 million and gain on extinguishment of debt of approximately $10.7 million. The change in asset and liabilities of $7.6 million mainly relates to increase in accrued expense and interest of $4.3 million in relation to increase in construction fees for Project Kati and D2 , legal fees, financing costs, and bonus accrual. In addition, there was a $2.0 million increase in accounts payable due to timing and billing of invoices, and a $3.0 million increase in customer deposits due to new contract agreements being entered into. The other changes in assets and liabilities of approximately $1.7 million mainly related to increase in accounts receivable and other current assets related to timing and billing amounts of invoices, deferred revenue in relation to a revenue contract, in addition to the payment made of $0.7 million to HPE in January 2025, offset by a decrease in other long-term assets of $1.7 million in relation to receipt of Briscoe deposit in January 2025 and increase in customer deposits for hosting agreements.

Net cash used in operations was approximately $5.1 million during the year ended December 31, 2024. We had a net loss for the year ended December 31, 2024 of approximately $58.3 million. Results included cost of revenue in connection with the HPE Agreement for $5.7 million. Non-cash items included approximately $6.2 million of depreciation expense and $9.5 million of amortization expenses, approximately $28.6 million on loss on contract, $5.3 million of stock compensation expenses, $1.6 million of loss on debt extinguishment and revaluation, $5.7 million in fair value adjustment losses, $2.0 million in debt issuance costs, $760 thousand in provision for credit losses, and $351 thousand amortized deferred financing costs. These non-cash items were offset with a deferred tax benefit of $2.5 million. The change in assets and liabilities is mainly due to an increase in prepaid expenses and other long term assets by $8.1 million due to a prepayment of an arrangement with HPE of $10.3 million that was being amortized over the life of the agreement and a decrease in customer deposits and other liabilities of $1.7 million due to timing of deposits applied in December 2024, offset by an increase in accrued expenses and accounts payable of approximately $5.5 million in relation to NYDIG interest, and related bills associated with D2 and Project Kati. The other changes in assets and liabilities were not material.

**Investing Activities**

Net cash used in investing activities during the year ended December 31, 2025 was approximately $31.9 million consisting mainly of capital expenditures of $28.1 million, which consist of additions to property, plant, and equipment offset with transfers from deposits on equipment, and $3.7 million deposit on equipment purchases. Net cash used in investing activities during the year ended December 31, 2024 was approximately $13.2 million consisting mainly of capital expenditures of $8.9 million and increase in deposits on equipment of $4.4 million, primarily related to the development of D2.

As of December 31, 2025, the Borrowers were not in compliance with the minimum Forward Contracted Debt Service Coverage Ratio covenant under the Credit Agreement. On March 26, 2026, the Agent provided a limited waiver of this covenant.

On March 12, 2025, the SW Borrower, a Delaware limited liability company and subsidiary of SW Holdings, itself a subsidiary of SDI, a Nevada corporation and wholly owned subsidiary of the Company, entered into the Galaxy Loan Agreement with SW Holdings and Galaxy Digital LLC. The Galaxy Loan Agreement provides for a term loan facility in the principal amount of $5.0 million (the "Term Loan Facility"). The Term Loan Facility bears interest at a rate of 15.0% per annum, subject to an increase of 5.0% (for a total of 20.0%) in the event an Event of Default has occurred and is continuing. The Term Loan Facility matures on March 12, 2030 and includes scheduled payments over a five-year term. As of December 31, 2025, the outstanding principal balance is approximately $4.6 million as we were compliant with all debt covenants.

On June 20, 2024, pursuant to the terms and subject to the conditions of a Note Purchase Agreement (the "June SPA") by and among (i) Soluna AL CloudCo, LLC, a Delaware limited liability company ("CloudCo") and indirect wholly owned subsidiary of the Company, (ii) Soluna Cloud, Inc., a Nevada corporation, indirect wholly owned subsidiary of the Company, and parent of CloudCo ("Soluna Cloud"), (iii) the Company and (iv) the accredited investor named therein (the "Investor"), CloudCo issued to the Investor a secured promissory note in a principal amount equal to $12.5 million (the "Green Cloud Secured Note"). The Green Cloud Secured Note accrues interest at a rate 9.0% per annum, subject to adjustment upon an event of default. The Green Cloud Secured Note matures on June 20, 2027. On July 12, 2024, the Company, CloudCo, Soluna Cloud, and the Investor entered into a First Amendment to the Note Purchase Agreement. Additional Notes were issued to additional accredited investors (the "Additional Investors") for $1.25 million ("Soluna CloudCo Additional Secured Note") on July 12, 2024 and are subject to the same terms and conditions as the June SPA financing. On October 1, 2024, CloudCo, Soluna Cloud and the Company entered into assignment and assumption agreements (the "Assignment Agreements") with the Additional Investors with respect to an aggregate of $1.25 million of notes issued by CloudCo. Pursuant to the Assignment Agreements, the Company will be able to purchase such notes for a purchase price of $750 thousand, or 60% of face value. The assignment and assumption will be effective once all conditions of the agreement are met including fulfilling the purchase price. The assignment and assumption occurred on March 14, 2025, therefore we extinguished the remaining third-party outstanding debt on the Additional Note, and a gain on extinguishment of the debt of approximately $551 thousand was recorded. In relation to the Green Cloud Secured Note, as of December 31, 2025, the Company had an outstanding principal balance of approximately $7.8 million.

On May 16, 2024, the SL Borrowing – 1, LLC, an affiliate of the Company (the "SDI Borrower"), entered into a loan (the "Equipment Loan Agreement" and the "Loan") with Soluna2 SLC Fund II Project Holdco LLC (the "Lender"). The Equipment Loan Agreement provides for the SDI Borrower to borrow, from time to time, up to $4.0 million, as further amended on February 28, 2025, to be used to purchase necessary equipment for the progression of D2 and Project Kati. Any loans made under the Equipment Loan Agreement have a maturity date of May 16, 2027 and bear interest at a rate of 15% per annum. The Equipment Loan Agreement includes customary covenants for loans of this nature, as well as a multiple on invested capital provision, which requires us to pay, in addition to principal and interest, an amount equal to the difference of (i) the greater of (a) the principal amount of the Loan being repaid plus all interest previously paid or simultaneously being paid to Lender in respect of such principal of the Loan, and (b) the principal amount of the Loan being repaid multiplied by three, minus (ii) the sum of the principal amount of the Loan being repaid plus all interest previously paid or simultaneously being paid to Lender in respect of such principal of the Loan. On March 21, 2025, the SDI Borrower drew down $250 thousand of the Loan with the Lender, in relation to Project Kati. In addition, on June 11, 2025 and July 16th, the SDI Borrower drew down an additional $269.2 thousand and $291.4 thousand of the Loan with the Lender, in relation to Project Kati. The total amount of equipment loans of $810.6 thousand was outstanding prior to the assignment of equipment and payoff of the loan. The SDI Borrower shall repay the Loans under these Borrowing Requests with a different MOIC Payment than as defined in the Equipment Loan Agreement. The MOIC Payment for these Borrowing Requests only, shall be an amount equal to the difference of (i) the greater of (a) the principal amount of the Loan being repaid plus all interest previously paid or simultaneously being paid to Lender in respect of such principal of the Loan, and (b) the principal amount of the Loan being repaid multiplied by three and three tenths (3.3), minus (ii) the sum of the principal amount of the Loan being repaid plus all interest previously paid or simultaneously being paid to Lender in respect of such principal of the Loan. As of the date prior to the payoff, the Company had approximately $180.6 thousand in Accrued interest payable in relation to the MOIC and 15% interest accruing on the Loan that was outstanding. On August 1, 2025, the SDI Borrower satisfied and repaid the Borrowing amount in full by issuing the SLC Class B Membership Interests in Soluna KKSL JVCo LLC ("Kati") project for 3.3 times the membership units ($810.6 thousand payoff equal to fair value of approximately $2.7 million for Class B membership units issued to SLC), as part of the contribution agreement between the parties. Through initial contributions of $810.6 thousand (debt repayment), SLC received 2,675 Class B Membership units, which constituted a 100% initial membership interest of Kati. The redemption of debt through equity created approximately a $1.7 million loss on debt extinguishment for the year ended December 31, 2025. On October 1, 2025, the Borrower, and Soluna2 Kati Project Holdco LLC ("Kati Lender"), entered into a borrowing

request of $1.075 million to cover the purchase of land to support construction of Project Kati Phase 2 under the terms of the Equipment Loan Agreement. For the land purchase, the MOIC payment was revised to replace 3.00 with 1.00. The $1.075 million remains outstanding as of December 31, 2025.

On May 9, 2023, Soluna DV ComputeCo, LLC ("DVCC") and Navitas West Texas Investments SPV, LLC entered into a 2-year Loan Agreement for $2.05 million. The unpaid principal balance of the Term Loan shall bear interest at per annum rate equal to 15%. As of December 31, 2025, the Navitas loan has been fully paid off.

On January 14, 2022, the Company effected an initial drawdown under the Master Equipment Finance Agreement ("MEFA") with NYDIG in the aggregate principal amount of approximately $4.6 million at 14% interest, followed by an additional drawdown of $9.8 million on January 26, 2022. On December 20, 2022, Soluna MC Borrowing 2021-1 LLC ("Borrower"), an indirect subsidiary of the Company, received a Notice of Acceleration and Repossession (the "NYDIG Notice") from NYDIG with respect to the MEFA Obligations under the MEFA were ring-fenced to the Borrower and its direct parent, Soluna MC LLC, and the Company was not party to any guaranty or other support agreement. On February 23, 2023, NYDIG foreclosed on the collateral, repossessing assets valued at approximately $3.4 million, of which approximately $560 thousand was first used to pay off accrued interest and penalties. On December 7, 2023, NYDIG filed a motion for summary judgment seeking approximately $10.3 million for unpaid principal, interest, and penalties. Following court proceedings, the parties agreed that the total outstanding loan principal balance would be approximately $9.2 million (the "Agreed Judgment Amount"). On September 29, 2025, the Borrower, Soluna MC, LLC (together with Borrower, the "NYDIG Defendants") and NYDIG entered into a Settlement Agreement (the "Settlement Agreement"), pursuant to which the NYDIG Defendants and NYDIG agreed to fully settle and resolve the Agreed Judgment Amount and all other matters relating to the NYDIG loans in exchange for the NYDIG Defendant's agreement to make certain settlement payments to NYDIG in accordance with the Settlement Agreement. Upon payment, NYDIG agreed to release the NYDIG Defendants and their affiliates from all related claims, other than obligations under the Settlement Agreement. The Company has recorded a gain on extinguishment of debt for the outstanding principal and accrued interest and penalties. As of December 31, 2025, the Settlement Agreement amount has been fully paid and satisfied.

**Critical Accounting Policies and Use of Estimates**

The prior discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with GAAP. Note 2 of the Consolidated Financial Statements included in this Annual Report includes a summary of our most significant accounting policies. The preparation of these consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosure of assets and liabilities. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, income taxes and share-based compensation. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Periodically, our management reviews our critical accounting estimates with the Audit Committee of our Board of Directors.

The significant accounting policies that we believe are most critical to aid in fully understanding and evaluating our consolidated financial statements include the following:

***Revenue Recognition***

We have entered into customer hosting contracts whereby we provide hosting services which include, electrical power to cryptocurrency mining customers, other utilities, and management of hosting facilities. Customer contracts can be a combination of a stated fixed amount per megawatt-hour ("MWh") ("Contract Capacity"), a percentage of the profit share of the daily net income from the customer's mining operations, or a combination thereof. Some contracts also include pass-through expenses which are not recognized in revenue. The actual monthly amounts are calculated after the close of each month and billed to the customers.

Cryptocurrency revenue consists of revenue recognized from our cryptocurrency mining facilities. Revenue is recognized at the cryptocurrency's realized cash value based upon the rates at cryptocurrency exchanges where we are registered. Cryptocurrencies are earned through participation with mining pool operators where the company provides hash rate services to the mining pool. The consideration received is payable in BitCoin based on a published formula Cryptocurrency is converted to U.S. dollars on a daily basis.

Starting in December 2023, we began providing emergency demand response solutions to ERCOT pursuant to a contractual commitment over defined service delivery periods. This contract includes a single promise to stand ready, on a monthly basis, to deliver a set amount of curtailment (committed capacity) per month when and if called upon by ERCOT. The Company believes that an output measure based on the monthly contractual MW stand-ready obligation is the best representation of the "transfer of value" to the customer. Accordingly, the Company recognizes monthly revenue based on the proportion of committed stand-ready capacity obligation that has been fulfilled to date.

***Fair Value Measurement***

The estimated fair value of certain financial instruments, including cash, accounts receivable and short-term debt approximates their carrying value due to their short maturities and varying interest rates. "Fair value" is the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. We utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based on the observability of the inputs used in the valuation methods, we are required to provide the following information according to the fair value accounting standards. These standards established a fair value hierarchy as specified that ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities are classified and disclosed in one of the following three categories:

---

| | |
|:---|:---|
| **Level 1:** | Quoted market prices in active markets for identical assets or liabilities, which includes listed equities. |
| **Level 2:** | Observable market-based inputs or unobservable inputs that are corroborated by market data. These items are typically priced using models or other valuation techniques. These models are primarily financial industry-standard models that consider various assumptions, including the time value of money, yield curves, volatility factors, as well as other relevant economic measures. |
| **Level 3:** | These use unobservable inputs that are not corroborated by market data. These values are generally estimated based upon methodologies utilizing significant inputs that are generally less observable from objective sources. |

---

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

We had warrants issued during 2024 and 2025 for purposes of equity financing and debt exchanges. Some of the warrants were considered freestanding equity-classified instruments due to their detachable and separately exercisable features and meet the indexation criteria within derivative accounting. Accordingly, those warrants were presented as a component of Stockholders' Equity in accordance with derivative accounting. Other warrants did not meet equity classification and were recorded as a liability until such warrants were exercised or an amendment to the warrant agreement occurred. We used a Black-Scholes simulation module in performing its fair value assumptions in relation to warrants issued during the course of the year. Inherent in a Black-Scholes simulation are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield.

On October 1, 2024, we modified the Series B Preferred Stock Agreement, in order to obtain consent from holders, which led to extinguishment accounting. We recorded a deemed dividend between the fair value of the modified preferred stock against the carrying value of the original preferred stock. The fair value of the modified preferred stock considered the conversion price of the preferred stock, assumption on the lockup expiration date, and closing price of the common stock on the lockup expiration date using daily volatility.

Consistent with the guidance in purchase accounting, the value of the Strategic Pipeline Contract, see Note 5, as of the acquisition date of October 2021 was estimated using an expected value approach, which probability-weights various future outcomes and uses certain Level 3 inputs.

As of December 31, 2025, and 2024, the fair values of cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable, and accrued expenses approximated their carrying values because of the short-term nature of these instruments.

***Share-Based Payments***

We award restricted stock to our employees and directors under the 2021 Plan and the Soluna Holdings, Inc. Amended and Restated 2023 Stock Incentive Plan (the "2023 Plan," together with the 2021 Plan, the "Plans"). The benefits provided under these plans are share-based payments and we account for stock-based awards exchanged for employee service in accordance with the appropriate share-based payment accounting guidance. Stock-based compensation represents the cost related to stock-based awards granted to employees and directors. We measure stock-based compensation cost at grant date based on the estimated fair value of the award and recognize the cost as expense on a straight-line basis in accordance with the vesting of the options (net of estimated forfeitures) over the option's requisite service period. We estimate the fair value of stock-based awards on the grant date using a Black-Scholes valuation model. We use the fair value method of accounting with the modified prospective application, which provides for certain changes to the method for valuing share-based compensation. The valuation provisions apply to new awards and to awards that are outstanding on the effective date and subsequently modified.

The determination of the fair value of share-based payment awards on the date of grant using an option-pricing model is affected by our stock price as well as assumptions regarding a number of complex and subjective variables. These variables include our expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, risk-free interest rate, and expected dividends.

Theoretical valuation models and market-based methods are evolving and may result in lower or higher fair value estimates for share-based compensation. The timing, readiness, adoption, general acceptance, reliability, and testing of these methods is uncertain. Sophisticated mathematical models may require voluminous historical information, modeling expertise, financial analyses, correlation analyses, integrated software and databases, consulting fees, customization, and testing for adequacy of internal controls.

For purposes of estimating the fair value of stock options granted using the Black-Scholes model, we use the historical volatility of our stock for the expected volatility assumption input to the Black-Scholes model, consistent with the accounting guidance. The risk-free interest rate is based on the risk-free zero-coupon rate for a period consistent with the expected option term at the time of grant. The expected option term is calculated based on our historical forfeitures and cancellation rates.

***Income Taxes***

We are subject to income taxes in the U.S. (federal and state). As part of the process of preparing our consolidated financial statements, we calculate income taxes for each of the jurisdictions in which we operate. This involves estimating actual current taxes due together with assessing temporary differences resulting from differing treatment for tax and accounting purposes that are recorded as deferred tax assets and liabilities, loss carryforwards, and tax credit carryforwards, for which income tax benefits are expected to be realized in future years. Deferred tax assets are reported net of a valuation allowance when it is more likely than not that a tax benefit will not be realized. The effect on deferred taxes of a change in tax rates is recognized in the period that includes the enactment date.

Significant management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities, and any valuation allowance recorded against our net deferred tax assets. We considered all available evidence, both positive and negative, such as historical levels of income and future forecasts of taxable income amongst other items in determining our valuation allowance. In addition, our assessment requires us to schedule future taxable income in accordance with accounting standards that address income taxes to assess the appropriateness of a valuation allowance, which further requires the exercise of significant management judgment.

We account for taxes in accordance with the asset and liability method of accounting for income taxes. Under this method, we must recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. The impact of our reassessment of our tax positions for these standards did not have a material impact on its results of operations, financial condition, or liquidity.

We are also currently subject to audit in various jurisdictions, and these jurisdictions may assess additional income tax liabilities against us. Developments in an audit, litigation, or in applicable laws, regulations, administrative practices,

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

principles, and interpretations could have a material effect on our operating results or cash flows in the period or periods in which such developments occur, as well as for prior and in subsequent periods.

Tax laws, regulations, and administrative practices in various jurisdictions may be subject to significant change, with or without notice, due to economic, political, and other conditions, and significant judgment is required in evaluating and estimating our provision and accruals for these taxes. There are many transactions that occur during the ordinary course of business for which the ultimate tax determination is uncertain. Our effective tax rates could be affected by numerous factors, such as intercompany transactions, earnings being lower than anticipated in jurisdictions where we have lower statutory rates and higher than anticipated in jurisdictions where we have higher statutory rates, the applicability of special tax regimes, losses incurred in jurisdictions for which we are not able to realize the related tax benefit, changes in foreign currency exchange rates, entry into new businesses and geographies, changes to our existing businesses and operations, acquisitions and investments and how they are financed, changes in our stock price, changes in our deferred tax assets and liabilities and their valuation, and changes in the relevant tax, accounting, and other laws, regulations, administrative practices, principles, and interpretations.

***Impairment of long-lived assets***

Management reviews long-lived assets, including finite lived intangible assets, property, plant and equipment, and other assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset, asset group, or investment may not be recoverable.

**Recent Accounting Pronouncements**

A discussion of recently adopted and new accounting pronouncements is included in Note [2] of the Consolidated Financial Statements included in this Annual Report.

**Item 7A. Quantitative and Qualitative Disclosures About Market Risk**

Not applicable.

**Item 8: Financial Statements and Supplementary Data**

The Company's Consolidated Financial Statements begin on page F-1 and are incorporated in this Item 8 by reference.

**Item 9: Changes in and Disagreements with Accountants on Accounting and Financial Disclosure** 

Not applicable.

**Item 9A: Controls and Procedures**

**(a)Evaluation of Disclosure Controls and Procedures**

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of SHI's disclosure controls and procedures as of December 31, 2025. The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. We recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and we necessarily apply our judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2025, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were not effective at the reasonable assurance level due to the following material weakness:

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the close of Soluna Holdings, Inc.'s Form 10-K for the year ended December 31, 2025, it was noted that certain control activities over balance sheet classification and presentation were not performed with sufficient precision aggregating to a material weakness. Specifically, errors were identified related to (i) the classification of current and long-term debt, (ii) a lease classification and valuation, and (iii) an overstatement in deposits on equipment and current liabilities. Although management corrected these errors prior to issuance of the filing, the nature and number of adjustments indicate that the Company's controls over balance sheet classification and presentation were not operating effectively.

Notwithstanding the existence of this material weakness, management has concluded that the Company's consolidated financial statements in its Annual Report on Form 10-K for the period ended December 31, 2025 are fairly stated in all material respects in accordance with generally accepted accounting principles in the United States of America.

*Remediation*:

Our Board of Directors and management take internal control over financial reporting and the integrity of our financial statements seriously. Management continues to work to improve its controls related to our material weaknesses. The remediation actions include: (i) enhancing design and documentation related to complex transactions and control activities, and (ii) developing robust review procedures to ensure the proper recording and reporting of the complex transactions. To achieve the timely implementation of the above, management has commenced the following actions and will continue to assess additional opportunities for remediation on an ongoing basis:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Implement more robust internal policies and procedures relating to balance sheet presentations, with a specific focus on establishing reliable controls over lease accounting to ensure the accuracy of financial reporting.

We cannot provide any assurance that these remediation efforts will be successful or that our internal control over financial reporting will be effective as a result of these efforts. In addition, we continue to evaluate and work to improve our internal control over financial reporting related to the identified material weakness, management may determine to take additional measures to address control deficiencies or determine to modify the remediation plan described above.

**(b)Management's Report on Internal Control Over Financial Reporting**

Management of our Company is responsible for establishing and maintaining adequate internal control over financial reporting, as that term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including the principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting using the criteria set forth in *Internal Control-Integrated Framework* (2013 version) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation using the criteria set forth in *Internal Control-Integrated Framework,* Management has concluded that our internal control over financial reporting was not effective as of December 31, 2025.

This annual report does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting. Our report was not subject to attestation by our independent registered public accounting firm pursuant to rules of the SEC that permit us to provide only Management's Report in this annual report.

**(c)Changes in Internal Control over Financial Reporting**

There have been no changes in our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, during our fiscal quarter ended December 31, 2025, that have materially affected, or are reasonable likely to materially affect, our internal control over financial reporting.

In considering the independence of the directors listed above, our board of directors considered the association of our directors with the holders of more than 5% of our common stock. There are no family relationships among any of our directors and executive officers.

**Item 11. Executive Compensation**

**Compensation Philosophy**

The primary objectives of our compensation policies are to attract, retain, motivate, develop, and reward our management team for executing our strategic business plan, thereby enhancing stockholder value, while recognizing and rewarding individual and Company performance. These compensation policies include: (i) an overall management compensation program that is competitive with companies of similar size or within our industries and (ii) long-term incentive compensation in the form of stock-based compensation that is aimed towards encouraging management to continue to focus on stockholder returns. Our executive compensation program ties a substantial portion of our executives' overall compensation to key strategic, financial, and operational goals, including: establishing and maintaining customer relationships; meeting revenue targets and profit and expense targets; growing our assets under management; evolving our AI business; and improving operational efficiency.

We believe that potential equity ownership in the Company is important to provide executive officers with incentives to build value for our stockholders. We believe that equity awards provide executives with a strong link to our short-term and long-term performance while creating an ownership culture to maintain the alignment of interests between our executives and our stockholders. When implemented responsibly, we also believe these equity incentives can function as a powerful executive retention tool.

The Compensation Committee of the Board, consisting entirely of independent directors, administers our compensation plans and policies, including the establishment of policies that govern base salary as well as short-term and long-term incentives for our executive management team.

The Toporek Employment Agreement provides for (i) annual performance bonuses based on attainment of one or more individual or business performance goals proposed by Mr. Toporek and approved by the Compensation Committee in its sole discretion (the "Annual Performance Bonus" and such target Annual Performance Bonus for a given calendar year, the "Target Performance Bonus"); and (ii) eligibility for employee benefit plans in effect until Mr. Toporek's employment with the Company is terminated.

In May 2021, the Compensation Committee approved a cash bonus in an aggregate amount of up to $100,000 based on the satisfaction of certain financial goals to be proposed by Mr. Toporek and approved by the Compensation Committee. Further, the Compensation Committee approved a one-time grant of stock options to purchase 500,000 shares of Common Stock. The stock options vest in equal installments on the first, second and third anniversaries of May 13, 2021, so long as Mr. Toporek remains in the service of the Company on each anniversary. The stock options expire five years after each applicable vesting date.

Pursuant to the Toporek Employment Agreement, if Mr. Toporek is terminated for any reason other than termination without cause or resignation for good reason, he is entitled to receive (i) a lump sum payment in the amount equal to the sum of Mr. Toporek's earned but unpaid Toporek Base Salary through the date of termination, (ii) his earned but unpaid Annual Performance Bonus for the calendar year preceding the date of termination, (iii) his accrued but unused vacation days as of the date of termination, (iv) reimbursement for any unreimbursed business expenses incurred through the date of termination, and (v) any other benefits or rights Mr. Toporek will have accrued or earned through his date of termination under the terms of any employee benefit plan. Additionally, if Mr. Toporek is terminated without cause or he resigns for good reason, subject to satisfaction of certain release conditions, he will also be entitled to coverage under any health insurance plan covering Mr. Toporek for 12 months after the termination of his employment, three years of his then-current Toporek Base Salary and the Target Performance Bonus for the calendar year containing the date of termination, both paid in a single lump sum in cash on the first regular Company payroll date next following the 60th calendar day following the date of termination.

**David Michaels**

In connection with Mr. Michaels' appointment as interim CFO and Treasurer, effective August 21, 2025, the Company and Mr. Michaels entered into a consulting agreement, effective August 21, 2025 (the "Consulting Agreement"). The Consulting Agreement provides for a four month term providing for consulting fees of $30,000 per month, with the potential to extend the monthly term in the search for a new CFO. Under the Consulting Agreement, the Company agreed to provide Mr. Michaels with D&O insurance until the five year anniversary of the termination or expiration of the Consulting Agreement and to reimburse Mr. Michaels for all reasonable and approved out-of-pocket expenses incurred in connection with the performance of his duties under the Consulting Agreement. The Company may terminate the Consulting Agreement at any time upon thirty days written notice to Mr. Michaels.

**Long-Term Equity Incentive Compensation**

Equity awards typically take the form of stock options, restricted stock grants, or restricted stock units under our equity compensation plans. Authority to make equity awards to executive officers rests with the Compensation Committee. In determining the size of awards for new or current executives, the Compensation Committee consider the competitive market, strategic plan performance, contribution to future initiatives, benchmarking of comparative equity ownership for executives in comparable positions at similar companies, individual option history, and recommendations of our Chief Executive Officer and Chairman.

The timing of all equity awards for our named executive officers have coincided with either employment anniversary dates or our annual meeting dates, or such equity awards are granted at the next scheduled meeting of the Compensation Committee following the completion or assignment of the applicable objectives. We do not time equity grants to our executives in coordination with the release of material non-public information, nor do we impose any equity ownership guidelines on our executives.

**Outstanding Equity Awards at Fiscal Year End**

• We have been or are to be a participant;

• the amount involved exceeded or will exceed the lesser of $120,000 or 1% of our total assets at year-end for our last two completed fiscal years; and

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

• any of our directors, executive officers or beneficial owners of more than 5% of our capital stock, or any immediate family member of, or person sharing the household with, any of these individuals or entities, had or will have a direct or indirect material interest, other than compensation and other arrangements that are described in the section titled "Executive Compensation."

***HEL Transactions***

On October 29, 2021, the Company completed the Soluna Callisto acquisition pursuant to a merger agreement (the "Merger Agreement"). The purpose of the transaction was for SCI to acquire substantially all of the assets (other than those assets physically located in Morocco) formerly held by Harmattan Energy, Ltd. (formerly Soluna Technologies, Ltd.) ("HEL"), which assets consisted of SCI's existing pipeline of certain cryptocurrency mining projects that HEL previously transferred to SCI, which was formed expressly for this purpose, and to provide SCI with the opportunity to directly employ or retain the services of four individuals whose services it had retained through HEL prior to the merger. As a result of the merger, each share of common stock of Soluna Callisto issued and outstanding immediately prior to the effective time of the merger, other than shares owned by the Company or any of our subsidiaries, was canceled and converted into the right to receive a proportionate share of up to 118,800 shares (the "Merger Shares") of Mechanical Technology, Incorporated common stock, payable upon the achievement of certain milestones.

Due to conditions being met within the Merger Agreement in relation to energization and retention of employees, the Company has advised SCI US Holdings LLC, a Delaware limited liability company, who is the sole Effective Time Holder (as defined in the Merger Agreement) of the right to receive the Merger Shares of the Company and that 19,800 Merger Shares were issued on May 26, 2023, 39,600 Merger Shares were issued on October 10, 2023, and 17,820 Merger Shares were issued on October 8, 2025. SCI US Holdings LLC has consented to the issuance of such Merger Shares as required under the Merger Agreement and has directed the Company to issue such Merger Shares to its affiliate, HEL. Following the issuance of the 77,220 Merger Shares, a total of 41,580 Merger Shares remains available for possible issuance through October 29, 2026 pursuant to the terms of the Merger Agreement as of December 31, 2025. On February 6, 2026, the Company issued an additional 10,692 Merger Shares, due to 18 MW of energization being met, as such as of the date of these consolidated financial statements, a total of 30,888 Merger Shares remains available for possible issuance through October 29, 2026.

Four of the Company's directors have various affiliations with HEL.

Michael Toporek, the former Chief Executive Officer, and current Executive Director of the Company, owns (i) 90% of the equity of Soluna Technologies Investment I, LLC, which owns 57.9% of HEL and (ii) 100% of the equity of MJT Park Investors, Inc., which owns 3.1% of HEL, in each case, on a fully diluted basis. Mr. Toporek does not own directly, or indirectly, any equity interest in Tera Joule, LLC ("Tera Joule"), which owns 9.2% of HEL; however, as a result of his 100% ownership of Brookstone IAC, Inc. ("Brookstone IAC"), which is the manager of Tera Joule, he has dispositive power over the equity interests that Tera Joule owns in HEL.

In addition, one of the Company's directors, Matthew E. Lipman, serves as a director and is currently acting as President of HEL. Mr. Lipman does not directly own any equity interest in Tera Joule, which owns 9.2% of HEL; however, as a result of his position as a director and officer of Brookstone IAC, which is the manager of Tera Joule, he has dispositive power over the equity interests that Tera Joule owns in HEL. As a result, the approximate dollar value of the amount of Mr. Toporek's and Mr. Lipman's interest in the Company's transactions with HEL for the year ended December 31, 2025 was $0 and $0.

John Belizaire, the Company's Chief Executive Officer, and John Bottomley, who were elected to the Board upon the effective time of SCI's acquisition of Soluna Callisto, serve as directors of HEL. In addition, Mr. Belizaire is the beneficial owner of 1,317,567 shares of common stock of HEL and 102,380 Class Seed Preferred shares, which are convertible into 86,763 shares of common stock of HEL. These interests give Mr. Belizaire an ownership of 10.54% in HEL. Mr. Belizaire also owns an interest in HEL indirectly through his 5.0139% interest of Tera Joule's 965,945 Class Seed Preferred shares, which are convertible into 818,596 shares of common stock of HEL. Mr. Bottomley is the beneficial owner of 96,189, or approximately 0.72%, of the outstanding shares of common stock of HEL.

The Company's investment in HEL was initially carried at the cost of investment and was $750 thousand. Based on evaluation of projections for the Company's investment in HEL, the Company fully impaired the equity investment of $750 thousand as of December 31, 2022, writing it down to $0.

The Company owned approximately 1.79% of HEL, calculated on a converted fully diluted basis, as of December 31, 2025. The Company may enter into additional transactions with HEL in the future.

**Policies and Procedures for Related Party Transactions**

We have adopted a written policy requiring that all related person transactions be reported to our executive management and/or the Board and approved or ratified by the Audit Committee. In completing its review of proposed related person transactions, the Audit Committee considers the aggregate value of the transaction, whether the transaction was undertaken in the ordinary course of business, the nature of the relationships involved, and whether the transaction is on terms comparable to those that could be obtained in arm's length dealings with an unrelated third party.

**Director Independence**

Pursuant to the rules of Nasdaq, a director will only qualify as an "independent director" if, in the opinion of that company's board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Under such rules, the Board has determined that Messrs. Bottomley, Hazelip, Hirshfield, Marusak, and Phelan are "independent directors," as defined by the rules and listing standards of Nasdaq. Messrs. Michaels, Belizaire, Lipman and Toporek are not independent directors under the Nasdaq rules. In making such independence determinations, our board of directors considered the relationships that each non-employee director has with us and all other facts and circumstances that our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. In considering the independence of the directors listed above, our board of directors considered the association of our directors with the holders of more than 5% of our common stock. There are no family relationships among any of our directors and executive officers.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Board of Directors and

Stockholders of Soluna Holdings, Inc. and Subsidiaries

**Opinion on the Financial Statements**

We have audited the accompanying consolidated balance sheets of Soluna Holdings, Inc. and Subsidiaries (the Company) as of December 31, 2025 and 2024, and the related consolidated statements of operations, changes in equity, and cash flows for each of the years in the two-year period ended December 31, 2025, and the related notes (collectively referred to as the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

**Basis for Opinion**

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matters**

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

***Fair value of Warrants***

<u>Description of the Matter</u>

As discussed in Note 12 to the consolidated financial statements, the Company had a total of approximately 30.6 million common stock warrant shares outstanding as of December 31, 2025. The Company uses option pricing models to estimate the fair value of the warrants using various market-based inputs.

We identified the fair value measurement of the warrants as a critical audit matter. Specifically, there was a high degree of subjectivity and judgment in evaluating the determination of the expected volatility inputs used in the option pricing

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

models for the warrants. Historical, implied, and peer group volatility levels provide a range of possible expected volatility inputs and the fair value estimates for the warrants are sensitive to the expected volatility inputs.

<u>How We Addressed the Matter in Our Audit</u>

The primary procedures we performed to address this critical audit matter included gaining an understanding of certain internal controls over the Company's process to measure the fair value of the warrants. This included understanding of controls related to the evaluation of observable market information used in the determination of the expected volatility inputs. We didn't test the operating effectiveness of these controls. We obtained and evaluated the underlying warrant agreements and traced the inputs into the fair value calculation. We also involved our firm's valuation professionals with specialized skills and knowledge, who assisted in:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evaluating the expected volatility inputs by comparing them against our separately derived shadow calculation of volatility; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• developing a shadow calculation of value of the warrants using our separately derived volatility and comparing it to the value calculated by the Company.

***Going Concern Assessment***

<u>Description of the Matter</u>

As discussed in Note 1 to the consolidated financial statements, the Company incurred recurring operating losses, had negative cash flows from operations, and has significant outstanding debt and commitments for capital expenditures. These conditions raised substantial doubt about the Company's ability to continue as a going concern within one year after the issuance of the consolidated financial statements.

Management evaluated these conditions and developed plans to alleviate the substantial doubt, including securing additional debt and equity financing and, if necessary, implementing cost reduction initiatives.

We identified the evaluation of the Company's ability to continue as a going concern as a critical audit matter due to the significant judgment involved in assessing the feasibility and sufficiency of management's plans, particularly regarding projected cash flows and access to financing.

<u>How We Addressed the Matter in Our Audit</u>

Our audit procedures related to this matter included, among others:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Evaluating management's going concern assessment in accordance with relevant accounting standards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Assessing the reasonableness of key assumptions used in cash flow forecasts including timing of projected debt &nbsp;&nbsp;&nbsp;&nbsp;and equity financing, revenue projections, margins and timing of expenditures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Inspecting agreements related to new financing arrangements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Testing the mathematical accuracy of the forecast model.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Assessing the Company's historical accuracy in forecasting results.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Evaluating whether management's plans, including additional financing, were probable of being effectively implemented.

**Notes to Consolidated Financial Statements**

**1. Nature of Operations**

***Description of Business***

*Unless the context requires otherwise in these notes to the Company's consolidated financial statements (the "Consolidated Financial Statements"), the terms "SHI,", " the "Company," "we," "us," and "our" refer to Soluna Holdings, Inc. together with its consolidated subsidiaries, "SDI" refers to Soluna Digital, Inc. and previously, "SCI" refers to Soluna Computing, Inc., formerly known as EcoChain, Inc., "Soluna Cloud" or "Cloud" refers to Soluna Cloud, Inc., and "SEI" refers to Soluna Energy, Inc.*

Soluna Holdings, Inc. ("SHI") is a digital infrastructure company that specializes in transforming surplus renewable energy into computing resources. The Company's strategy is to operate modular data centers co-located with wind, solar, and hydroelectric power plants, supporting compute-intensive applications, including Bitcoin mining, generative AI, and high-performance computing ("HPC"). This approach aims to create a more sustainable grid while providing cost-effective and environmentally friendly computing solutions.

Soluna Holdings, Inc., was originally incorporated in the State of New York in 1961 as Mechanical Technology, Incorporated and reincorporated in the State of Nevada on March 24, 2021. Headquartered in Albany, New York, the Company changed its name from "Mechanical Technology, Incorporated" to Soluna Holdings, Inc. on November 2, 2021. On October 29, 2021, Soluna Callisto merged into Soluna Computing, Inc. ("SCI"), a private green data center development company. SHI currently conducts its business through its wholly owned subsidiary, Soluna Digital, Inc. ("SDI"). Additionally, SHI formed Soluna Cloud, Inc. ("Soluna Cloud") on March 24, 2024, to operate cloud, colocation, and data hosting services related to high performance computing and AI. On April 2, 2024, SHI formed Soluna Energy, Inc. ("SEI") to own and manage renewable energy power purchase agreements and land leases through a series of service subsidiaries.

Currently the Company has four operating sites under management. In 2021, the Company constructed a 25 MW data center and commenced operations in its Murray, Kentucky location ("Project Sophie"). The Company's Texas site ("Project Dorothy"), located at a wind farm, holds the potential for up to 100 MW of power generation. By June 2024, SHI had energized 50 MW of the site across two phases, Project Dorothy 1A and 1B. As of December 31, 2025, SHI holds a 15% Class B membership interest in Soluna DVSL ComputeCo, LLC ("DVSL"), owner of Project Dorothy 1A, and a subsidiary of SHI holds a 100% Class A membership interest in DVSL. SHI also holds a 51% ownership interest in Soluna DV ComputeCo, LLC ("DVCC"), owner of Project Dorothy 1B. On July 22, 2024, the Company closed financing for the 48 MW modular data center (the "Project Dorothy 2"). Project Dorothy 2 is financed by Soluna2 SLC Fund II Project Holdco LLC, an investment vehicle of Spring Lane Capital ("SLC") and SDI. As of December 31, 2025, SDI has a 100% Class A membership and a 0% Class B membership interest in Project Dorothy 2. On July 22, 2025, the Company closed financing with Spring Lane Capital for a 35 megawatt (MW) expansion of Project Kati in Texas with Project Kati 1. The funds and further contributions are being used for the construction of Project Kati 1 that began in the third quarter of 2025. As of December 31, 2025, SDI has 100% Class A membership and 20% Class B membership interest in Project Kati 1.

***Liquidity and Capital Resources***

The Company has historically incurred recurring operating losses and negative cash flows from operations. For the year ended December 31, 2025, the Company reported a net loss of $57.0 million and used $9.1 million in net cash for operating activities. As of December 31, 2025, we had total debt outstanding of approximately $26.8 million as summarized in Note 8. In addition, we had outstanding commitments related to Soluna Digital Inc. ("SDI") of approximately $27.0 million in capital expenditures related to Project Kati. Additionally, as of December 31, 2025, the Company maintained an outstanding contract liability of approximately $19.3 million related to the termination of a prior cloud services agreement. These conditions initially raised substantial doubt about the Company's ability to continue as a going concern.

*Management's Mitigating Plans*

Management has implemented several strategic plans to mitigate these conditions, which have significantly improved the Company's liquidity profile:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Substantial Liquidity and Capital Markets Access:** The Company dramatically improved its financial position in 2025, raising $119.4 million in net proceeds from financing activities. For further information on the

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

Company's Standby Equity Purchase Agreement ("SEPA"), At-the-Market Offering Agreement ("ATM") with H.C. Wainwright ("Wainwright"), July Securities Purchase Agreement ("July SPA"), and December Securities Purchase Agreement ("December SPA"), please refer to Note 9 for further details. The Company's had cash on hand for available use of approximately $76.4 million as of December 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Committed Equity Financing:** The Company maintains a SEPA with YA II PN, LTD ("YA"), with $18.8 million in remaining capacity available at the Company's sole discretion. Furthermore, on March 24, 2026, the Company has finalized a commercial agreement to extend this SEPA capacity to $250.0 million. See Note 17 for details on the updated SEPA.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Project Debt and Expense Management:** Management successfully closed project-level financing with Generate for commitment up to $100.0 million and is in compliance with all debt covenants. See Note 8 for details. Furthermore, management maintains strict control over discretionary Selling, General, and Administrative expenses and capital expenditures, with the proven ability to curtail expenses if funding availability changes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Operating Performance and Scale:** Management's 2026 operating plan forecasts growth in consolidated revenue and in adjusted EBITDA. Notably, the majority of the Company's revenues are fixed-fee or demand-response, providing stability against cryptocurrency price volatility.

The future use of the Company's available liquidity will be based upon the ongoing review of the funding needs of the Company's businesses, proper allocation of its resources, and the timing of cash flow generation. To the extent that we desire to access alternative sources of capital, market conditions could adversely impact our ability to do so at that time and at terms favorable to the Company.

The Company believes that its working capital, cash position and restricted cash to be released over the next 12 months, together with other key assumptions, support the Company's conclusion that it has sufficient capital to fund its on-going operations for a period of at least 12 months subsequent to the issuance of the accompanying consolidated financial statements. Key assumptions are based on factors such as forecasted sales and costs, debt obligations, the Company's right to direct Wainwright to purchase shares from the Company under the ATM equity offering program, and the Company's right to direct YA to purchase shares from the Company under the SEPA.

**2. Accounting Policies**

***Basis of Presentation***

In the opinion of management, the Consolidated Financial Statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair statement of the results for the periods presented in accordance with U.S. GAAP.

***Principles of Consolidation***

The Consolidated Financial Statements include the accounts of the Company and its subsidiaries, including the Company's variable and voting interest entities disclosed in Note 15. All intercompany balances and transactions are eliminated in consolidation.

***Reclassification***

Certain prior year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the reported results of operations or net assets.

***Correction of an Error***

While preparing the Company's Form 10-Q for the three and nine months ended September 30, 2025, the Company identified the following error related to the presentation of basic and diluted Earnings Per Share ("EPS") in its historical filing for the year ended December 31, 2024, and for the quarters ended June 30, 2024, September 30, 2024, March 31, 2025, and June 30, 2025:

 ● Inclusion of the restricted stock awards that had not yet vested.

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

In accordance with SEC Staff Accounting Bulletin No. 99, "Materiality," and SEC Staff Accounting Bulletin No. 108, "Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements;" the Company evaluated the errors and has determined that the related impacts were not material to any prior annual or quarterly report, but that correcting the cumulative impact of such errors would be significant to our EPS for the year ended December 31, 2025. Accordingly, the Company has corrected such immaterial errors by adjusting its December 31, 2024 consolidated statement of operations related to the calculation of earnings per share. The Company also corrected previously reported interim financial information for such immaterial errors in future filings, as applicable. The following summarizes the effect of the revision on each financial statement line item.

The following analysis provides a comparison amongst the basic and diluted EPS as reported on the Form 10-Q for the quarter ended June 30, 2024, and the final revised basic and diluted EPS calculation to correct all identified errors:

***Use of Estimates***

The Consolidated Financial Statements have been prepared in accordance with U.S. GAAP, which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

***Property, Plant, and Equipment***

Property, plant and equipment are stated at cost and depreciated using the straight-line method over their estimated useful lives as follows:

---

| | |
|:---|:---|
| Leasehold improvements | Lesser of the life of the lease or the useful life of the improvement |
| Computers and related software | 3 to 5 years |
| Cryptocurrency miners | 3 years |
| Machinery and equipment | 5 to 15 years |
| Office furniture, equipment and fixtures | 2 to 10 years |
| Buildings | 30-40 years |
| Purchased pre-fabricated buildings | 15-20 years |

---

Significant additions or improvements extending assets' useful lives are capitalized; normal maintenance and repair costs are expensed as incurred. The costs of fully depreciated assets remaining in use are included in the respective asset and accumulated depreciation accounts. When items are sold or retired, related gains or losses are included in net (loss) income.

***Intangible assets***

Intangible assets include the Strategic Pipeline Contract with an estimated useful life of 5 years, assembled workforce of individuals included as part of the asset acquisition that occurred in October 2021 with an estimated useful life of 5 years and patents with an estimated useful life of 15-25 years. The Company amortizes the intangible assets over their estimated useful lives on a straight-line basis. The Company does not recognize internally developed patents as intangible assets, however legal costs associated with defending such patents are capitalized as long-lived assets.

***Income Taxes***

The Company is subject to income taxes in the U.S. (federal and state). As part of the process of preparing the Consolidated Financial Statements, the Company calculates income taxes for each of the jurisdictions in which the Company operates. This involves estimating actual current taxes due together with assessing temporary differences resulting from differing treatment for tax and accounting purposes that are recorded as deferred tax assets and liabilities, loss carryforwards and tax credit carryforwards, for which income tax benefits are expected to be realized in future years. A valuation allowance has been established to reduce deferred tax assets, if it is more likely than not that all, or some portion, of such deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized in the period that includes the enactment date.

Significant management judgment is required in determining the Company's provision for income taxes, deferred tax assets and liabilities, and any valuation allowance recorded against the Company's net deferred tax assets. The Company considers all available evidence, both positive and negative, such as historical levels of income and future forecasts of taxable income amongst other items in determining the Company's valuation allowance. In addition, the Company's assessment requires the Company to schedule future taxable income in accordance with accounting standards that address income taxes to assess the appropriateness of a valuation allowance, which further requires the exercise of significant management judgment.

The Company accounts for taxes in accordance with the asset and liability method of accounting for income taxes. Under this method, the Company must recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. The impact of the Company's reassessment of its tax positions for these standards did not have a material impact on its results of operations, financial condition, or liquidity.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

The Company is currently subject to audit in various jurisdictions, and these jurisdictions may assess additional income tax liabilities against us. Developments in an audit, litigation, or in applicable laws, regulations, administrative practices, principles, and interpretations could have a material effect on the Company's operating results or cash flows in the period or periods in which such developments occur, as well as for prior and in subsequent periods.

Tax laws, regulations, and administrative practices in various jurisdictions may be subject to significant change, with or without notice, due to economic, political, and other conditions, and significant judgment is required in evaluating and estimating the Company's provision and accruals for these taxes. There are many transactions that occur during the ordinary course of business for which the ultimate tax determination is uncertain. The Company's effective tax rates could be affected by numerous factors, such as intercompany transactions, earnings being lower than anticipated in jurisdictions where the Company has lower statutory rates and higher than anticipated in jurisdictions where the Company has higher statutory rates, the applicability of special tax regimes, losses incurred in jurisdictions for which the Company is not able to realize the related tax benefit, entry into new businesses and geographies, changes to its existing businesses and operations, acquisitions and investments and how they are financed, changes in the Company's stock price, changes in its deferred tax assets and liabilities and their valuation, and changes in the relevant tax, accounting, and other laws, regulations, administrative practices, principles, and interpretations.

***Equity Investments without Readily Determinable Fair Values***

The Company owns approximately 1.79% of Harmattan Energy Limited ("HEL")'s outstanding stock, calculated on a fully-diluted basis, as of December 31, 2025 and 2024. Our equity investment in HEL is accounted for under the measurement alternative. Equity securities measured and recorded using the measurement alternative are recorded at cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes. Adjustments resulting from impairments and observable price changes are recorded in the income statement. The Company currently holds a cost of investment of $0 as of December 31, 2025 and 2024.

***Equity Method Investments***

The Company's consolidated net income or loss will include our proportionate share, if any, of the net income or loss of our equity method investee. When the Company records its proportionate share of net income, it increases equity income (loss), net in our consolidated statements of operations and our carrying value in that investment. Conversely, when the Company records its proportionate share of a net loss, it decreases equity income (loss), net in our consolidated statements of operations and our carrying value in that investment. When the Company's carrying value in an equity method investee company has been reduced to zero, no further losses are recorded in the Company's financial statements. When the investee company subsequently reports income, the Company will not record its share of such income until it equals the amount of its share of losses not previously recognized.

As of December 31, 2025, the Company owned approximately 47.5% of MeOH Power, Inc.'s outstanding common stock, or 75,049,937 shares. The number of shares of MeOH Power, Inc.'s common stock authorized for issuance is 240,000,000 as of December 31, 2025. The Company records its investment in MeOH Power, Inc. using the equity method of accounting. The fair value of the Company's interest in MeOH Power, Inc. has been determined to be $0 as of December 31, 2025 and December 31, 2024, based on MeOH Power, Inc.'s net position and expected cash flows.

***Variable Interest Entities and Voting Interest Entities***

Soluna consolidates those entities in which it has a direct or indirect controlling financial interest based on either the Variable Interest Entity ("VIE") model or the Voting Interest Entity ("VOE") model.

VIEs are entities that, by design, either (i) lack sufficient equity to permit the entity to finance its activities independently, or (ii) have equity holders that do not have the power to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the entity's expected losses, or the right to receive the entity's expected residual returns. The Company consolidates a VIE when it is the primary beneficiary, which is the party that has both (i) the power to direct the activities that most significantly impact the VIE's economic performance and (ii) through its interests in the VIE, the obligation to absorb expected losses or the right to receive expected benefits from the VIE that could potentially be significant to the VIE.

To assess whether Soluna has the power to direct the activities of a VIE that most significantly impact the VIE's economic performance, Soluna considers all the facts and circumstances, including its role in establishing the VIE and its ongoing

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

rights and responsibilities. This assessment includes identifying the activities that most significantly impact the VIE's economic performance and identifying which party, if any, has power over those activities. In general, the parties that make the most significant decisions affecting the VIE (management and representation on the Board of Directors) and have the right to unilaterally remove those decision-makers are deemed to have the power to direct the activities of a VIE.

To assess whether Soluna has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, Soluna considers all of its economic interests, which primarily include equity investments in the entity that are deemed to be variable interests in the VIE. This assessment requires Soluna to apply judgment in determining whether these interests, in the aggregate, are considered potentially significant to the VIE. Factors considered in assessing the significance include: the design of the VIE, including its capitalization structure; subordination of interests; payment priority; and who handles the day-to-day activities.

At the VIE's inception Soluna determines whether it is the primary beneficiary and if the VIE should be consolidated based on the facts and circumstances. Soluna then performs on-going reassessments of the VIE based on reconsideration events and reevaluates whether a change to the consolidation conclusion is required each reporting period. Refer to Note 15.

Entities that do not qualify as a VIE are assessed for consolidation under the VOE model. Under the VOE model, Soluna consolidates the entity if it determines that Soluna holds control over significant decisions and the other equity holders do not have substantive voting, participating or liquidation rights. Refer to Note 15.

***Non-Controlling Interests***

The ownership interest held by owners other than the Company in less than wholly-owned subsidiaries are classified as non-controlling interests. The value attributable to the non-controlling interests is presented on the consolidated balance sheets separately from the equity attributable to the Company. Net income (loss) attributable to non-controlling interests are presented separately on the consolidated statements of operations.

***Fair Value Measurement***

The estimated fair value of certain financial instruments, including cash, accounts receivable and short-term debt approximates their carrying value due to their short maturities and varying interest rates. "Fair value" is the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based on the observability of the inputs used in the valuation methods, the Company is required to provide the following information according to the fair value accounting standards. These standards established a fair value hierarchy as specified that ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities are classified and disclosed in one of the following three categories:

---

| | |
|:---|:---|
| **Level 1:** | Quoted market prices in active markets for identical assets or liabilities, which includes listed equities. |
| **Level 2:** | Observable market-based inputs or unobservable inputs that are corroborated by market data. These items are typically priced using models or other valuation techniques. These models are primarily financial industry-standard models that consider various assumptions, including the time value of money, yield curves, volatility factors, as well as other relevant economic measures. |
| **Level 3:** | These use unobservable inputs that are not corroborated by market data. These values are generally estimated based upon methodologies utilizing significant inputs that are generally less observable from objective sources. |

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The Company has used a Black-Scholes simulation module in performing its fair value assumptions in relation to warrants issued during 2025. Inherent in a Black-Scholes simulation are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its common stock warrants based on implied volatility from its traded warrants and historical volatility of select peers' common stock with a similar expected term of the Warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield on the grant date with a maturity similar to the expected remaining term of the warrants. The expected term of the warrants is assumed to be

------

equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company expects to remain at zero. The warrants were collectively classified as a Level 3 measurement within the fair value hierarchy because these valuation models involve the use of unobservable inputs relating to the Company's estimate of its expected stock volatility which was developed based on the historical volatility of a publicly traded set of peer companies.

In relation to the Generate Common Warrant discussed in Note 8, on September 28, 2025, the Company executed a side letter with the Holder in relation to the outstanding Generate Common Warrant to waive a clause in the Generate Common Warrant that has a requirement to reserve 2.0 million shares of common stock until there is an increase in the authorized shares of the Company. If the Company did not get shareholder approval to increase the authorized shares, then the Company would have to repurchase shares of common stock in the open market and hold those shares in treasury as a reserve for the Generate Common Warrant. The Company was still required to reserve the Generate Pre-Funded Warrant. As the Generate Common Warrant was contingent upon shareholder approval of increase of authorized shares, and if the Company did not get approval, the Company would need to repurchase shares of common stock in the open market, it created the Company to classify the Generate Common Warrant as a liability as of September 30, 2025. The change in classification of the Generate Common Warrant created a deemed dividend of approximately $3.8 million, in which was adjusted in the earnings per share calculation, see Note 11 for further details. The Generate Common Warrant was classified as a Level 3 measurement within the fair value hierarchy due to the use of a valuation model which involves the use of unobservable inputs. The Company notes that it obtained shareholder approval on November 7, 2025 to increase the authorized shares to 375 million, thereby amending the Generate Common Warrant back to the original treatment of equity classification.

The following table represents the significant fair value assumptions used for the Generate Warrants issued or revalued during the year ended December 31, 2025.

On July 15, 2025, the Company entered into a securities purchase agreement with the purchasers signatory thereto, pursuant to which the Company sold in a public offering (the "July 2025 Offering") an aggregate of (i) 8,794,544 shares of common stock (each a "Share" and collectively, the "Shares"); (ii) pre-funded warrants (the "Pre-Funded Warrants") to purchase 296,365 shares of common stock; (iii) Series A warrants (the "Series A Warrants") to purchase 9,090,909 shares of common stock; and (iv) Series B warrants (the "Series B Warrants," and together with the Series A Warrants, the "Common Warrants") to purchase 9,090,909 shares of common stock.

Based on review of the Series A and Series B warrants in relation to the July 2025 Offering, the warrants were liability treated. Based on a fair value assessment on July 17, 2025, the Series A and Series B warrants had a fair value of approximately $8.6 million. For the year ended December 31, 2025, all the Series A and Series B warrants were exercised in which the Company received approximately $10.0 million in gross proceeds, and due to change in fair value on date of exercise and the original fair value on July 17, 2025, there was a fair value adjustment loss of approximately $12.8 million for the year ended December 31, 2025.

direct offering: (i) 5,929,944 shares (the "December Shares") of the Company's common stock, (ii) pre-funded warrants (the "December Pre-Funded Warrants") to purchase up to 12,149,200 shares of Common Stock, and (iii) Series C Warrants (the "Series C Warrants") to purchase up to 18,079,144 shares of Common Stock (the "December Offering"). The purchase price for each share of Common Stock and accompanying Series C Warrant sold in the December Offering was $1.77. The Series C warrants have an exercise price of $1.65 per share, are exercisable immediately upon issuance, and will expire five years following the date of issuance. In addition, Placement Agent Warrants were issued to purchase up to 903,957 shares of Common Stock. The Placement Agent Warrants were classified within Mezzanine Equity on the consolidated financial statements as of December 31, 2025.

On October 25, 2021, pursuant to a securities purchase agreement dated October 20, 2021 (the "SPA), the Company issued to certain accredited investors Class A, Class B and Class C common stock purchase warrants (collectively, the "Warrants") The Warrants were considered freestanding equity-classified instruments due to their detachable and separately exercisable features and meet the indexation criteria within derivative accounting. Accordingly, the Warrants were presented as a component of Stockholders' Equity in accordance with derivative accounting. Any modifications or new additional warrants were subsequently revalued, including the Fourth Amendment on February 28, 2024, see Note 8 for details.

Following the debt extinguishment on July 19, 2022 as noted further in Note 8, the Convertible Notes will be accounted for under the fair value method on a recurring basis upon issuance (e.g., upon execution of the Addendum) per guidance within ASC 480, and at each subsequent reporting period, with changes in fair value reported in earnings. The Company had a subsequent Addendum Amendment on September 13, 2022, a Second Amendment on May 11, 2023, a Third Amendment on November 20, 2023, a Fourth Amendment on February 28, 2024, and Final Conversion inducement on December 12, 2024, which each caused a revaluation of the fair value on the executed Addendum Amendment, Second Amendment, Third Amendment, Fourth Amendment, and final inducement date. Although the Convertible Notes are not being accounted for under ASC 825-10, the substance of the debt is considered to be the same and is therefore considered outside the scope of ASC 470-60. As such, the Company performed a fair value analysis of the Convertible Notes. For the year-ended December 31, 2025 and 2024, the Company had Monte Carlo simulations run-out for the expected conversion dates of the Convertible Notes using risk free rates, annual volatility, daily trading volumes, likely conversion profiles, and other assumptions based on principal and accrued interest as of the year-end. The Company determined the fair value of the Convertible Notes using certain Level 3 inputs.

On December 12, 2024, the Company entered into an agreement with the remaining three Note Holders who held an outstanding principal balance as December 12, 2024, pursuant to which the three remaining Note Holders elected to immediately convert all of the outstanding principal of certain convertible notes into shares of the Company's common stock. The agreement satisfied the full outstanding debt owed to the remaining three Note Holders under the Convertible Notes and as such no further obligation remained for the Convertible Notes, see Note 8 for details.

On October 1, 2024, the Company modified the Series B Preferred Stock Agreement, which included a fixed reprice conversion of $5 per share from originally $135.25 per share, reprice of additional 60,000 warrants to a penny, an additional 140,000 new penny warrants being issued, and dividend payments being changed to annually from originally a one-time payment, which led to extinguishment accounting. The Company would record a deemed dividend of approximately $1.7 million between the fair value of the modified preferred stock against the carrying value of the original preferred stock. The Company performed a Monte Carlo simulation as of October 1, 2024 to determine the fair value of the modified preferred stock, in which the fair value considerations included the fixed conversion price of the preferred stock, assumption on the lockup expiration date, closing price of the common stock on the lockup expiration date using daily volatility, and risk free interest rates. The Company determined the fair value of the modified preferred stock using certain Level 3 inputs. In addition to the fair value of the preferred stock, as part of the modified preferred stock consideration, the Company performed a Black-Scholes simulation on the repriced and new penny warrants, using assumptions considered above similar to the convertible debt, and lastly applied a present value calculation on future dividends to be paid. See Note 9 for details on the modified Series B Preferred Stock.

***Revenue Recognition***

*Cryptocurrency Mining Revenue*

The Company recognizes revenue under ASC 606, Revenue from Contracts with Customers. The core principles of the revenue standard are that a company should recognize revenue to depict the transfer of promised good or services to customers in an amount that reflects the consideration to which the Company expects to be entitled for those goods or services. The following five steps are applied to achieve that core principle:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Step 1: Identify the contract with the customer

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Step 2: Identify the performance obligations in the contract

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Step 3: Determine the transaction price

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Step 4: Allocate the transaction price to the performance obligations in the contract

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Step 5: Recognize revenue when the Company satisfies a performance obligation

In order to identify the performance obligations in a contract with a customer, a company must assess the promised goods or services in the contract and identify each promised goods or service that is distinct. A performance obligation meets ASC 606's definition of a "distinct" good or service (or bundle of goods or services) if both of the following criteria are met: The customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer (i.e., the good or service is capable of being distinct), and the entity's promise to transfer the good or service to the customer is separately identifiable from other promises in the contract (i.e., the promise to transfer the good or service is distinct within the context of the contract).

If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct.

The transaction price is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer. The consideration promised in a contract with a customer may include fixed amounts, variable amounts, or both. When determining the transaction price, an entity must consider the effects of all of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Variable consideration

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Constraining estimates of variable consideration

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The existence of a significant financing component in the contract

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Noncash consideration

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Consideration payable to a customer

Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The transaction price is allocated to each performance obligation on a relative standalone selling price basis. The transaction price allocated to each performance obligation is recognized when that performance obligation is satisfied, at a point in time.

Providing computing power to solve complex cryptographic algorithms in support of the Bitcoin blockchain (in a process known as "solving a block") is an output of the Company's ordinary activities. The provision of providing such computing power is the only performance obligation in the Company's contracts with mining pool operators. The transaction consideration the Company receives, if any, is noncash consideration, which the Company measures at fair value on the date received, which is not materially different than the fair value at contract inception or the time the Company has earned the award from the pools. The consideration is all variable. Because it is not probable that a significant reversal of cumulative revenue will not occur, the consideration is constrained until the mining pool operator successfully places a block (by being the first to solve an algorithm) and the Company receives confirmation of the consideration it will receive, at which time revenue is recognized. There is no significant financing component in these transactions.

Cryptocurrencies are earned through participation with mining pool operators where the company provides hash rate services to the mining pool. Fair value of the cryptocurrency award received is determined using the quoted price of the related cryptocurrency where the Company is registered at the time of receipt. The mined cryptocurrency is immediately paid to the Coinbase wallet. Cryptocurrency is converted to U.S. dollars nearly everyday, as SDI is not in the business of accumulating material amounts of cryptocurrency on its balance sheet.

*Cryptocurrency data center hosting*

The Company has entered customer hosting contracts whereby the Company provides hosting services which include electrical power, other utilities, network connectivity, and management of hosting facility to cryptocurrency mining customers, and the customers pay a stated amount per MWh, a fixed rate, as well as a percentage of the profit share of net income from the customer's mining operations, or a combination thereof. Some contracts also include pass-through expenses which are not recognized in revenue. The actual monthly amounts are calculated after the close of each month and billed to the customer. If any shortfalls due to outages are experienced, service level credits may be made to customers to offset outages which prevented them from cryptocurrency mining. Customer contract security deposits are reflected as other liabilities and are made at the time the contract is signed and held until the conclusion of the contract relationship. In addition, the Company has a service agreement in which the Company provides managed Bitcoin capacity and hashrate over the term of the service agreement.

Deferred revenue is primarily from advance monthly payments received and revenue is recognized when service is completed. The Company has one agreement in which they received an upfront payment for a two-year term, in which contained a significant financing component in which the Company applied at a discount rate on the advance payment. As of December 31, 2025, the outstanding deferred revenue is approximately $1.0 million, in which the current portion of approximately $518 thousand is currently presented within Deferred revenue, and the noncurrent portion of approximately $495 thousand is presented within Other liabilities on the consolidated financial statements.

*Demand Response Service*

The Company provides emergency demand response solutions to ERCOT pursuant to a contractual commitment over defined service delivery periods. This contract includes a single promise to stand ready, on a monthly basis, to deliver a set amount of curtailment (committed capacity) per month when and if called upon by ERCOT. The Company has concluded this represents a series of distinct monthly services that are substantially the same, with the same pattern of transfer to the customer. Accordingly, the monthly promise to stand ready is accounted for as a single performance obligation. The Company is the principal in these arrangements as it has control over the services prior to those services being transferred to the customer.

Capacity fees are paid to the Company by ERCOT for its stand ready commitment to curtail MWs and are typically based on the Company's ability to deliver the committed capacity throughout the contractual delivery period. In general, if the Company fails to curtail the contracted MWs during energy or emergency dispatches, the MW shortfall results in a penalty that could require the Company to reduce the fees paid by the customer during the contract period.

In order to determine the transaction price, the Company estimates the amount of variable consideration at the outset of the contract either utilizing the expected value or most likely amount method, depending on the facts and circumstances relative to the contract. These estimates consider i) the contractual rate per MW, and ii) historical performance. The Company constrains (reduces) the estimates of variable consideration such that it is probable that a significant reversal of previously recognized revenue will not occur throughout the life of the contract. When determining if variable consideration should be constrained, management considers whether there are factors outside the Company's control that could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and magnitude of a potential reversal of revenue. These estimates are re-assessed each reporting period as required. In the event of an emergency dispatch, any earned energy fees are associated and allocated to the specific month of performance, as these fees meet the criteria to allocate variable consideration to a distinct monthly service within a series of distinct services that comprise the single performance obligation. Therefore, energy fees are recognized in the month in which the Company is called upon to deliver on its stand-ready obligation to curtail capacity.

The Company believes that an output measure based on the monthly contractual MW stand-ready obligation is the best representation of the "transfer of value" to the customer. Accordingly, the Company recognizes monthly revenue based on the proportion of committed stand-ready capacity obligation that has been fulfilled to date.

*High performance computing services*

The Company provided high performance computing ("HPC") services to support customers' generative AI workstreams. We have determined that HPC services were a single continuous service consisting of a series of distinct services that are substantially the same and have the same pattern of transfer (i.e., distinct days of service).

These services were consumed as they are received, and the Company recognized revenue over time using the variable allocation exception as it satisfies performance obligations. We applied this exception because we concluded that the nature of our obligations and the variability of the payment terms based on the number of GPUs providing HPC services were aligned and uncertainty related to the consideration was resolved on a daily basis as we satisfied our obligations. The Company recognized revenue net of consideration payable to customers, such as service credits, and accounted for as a reduction of the transaction price in accordance with guidance in ASC 606-10-32-25.

The Company, as it seeks to develop AI/HPC data center projects, may enter into customer hosting contracts whereby the Company, or its JV partners or affiliates, may provide hosting services which include electrical power, other utilities, network connectivity, and management of hosting facility to AI/HPC customers, and the customers pay a stated amount per megawatt-hour MWh, a fixed rate, as well as a percentage of the profit share of net income from the customer's mining operations, or a combination thereof. Some contracts may also include pass-through expenses which are not recognized in revenue. The actual monthly amounts will be calculated after the close of each month and billed to the customer. If any

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

shortfalls due to outages were to be experienced, service level credits may be made to customers to offset outages which prevent them from utilizing the AI/HPC facility. Customer contract security deposits, if applicable, would be reflected as other liabilities created at the time the contract is signed and held until the conclusion of the contract relationship.

***Cost of Cryptocurrency Mining and Data Center Hosting Revenue***

The Company's cost of revenue consists primarily of (i) direct production costs related to mining operations, including electricity costs, profit-sharing fees, and other relevant costs, but excluding depreciation and amortization, which are separately stated in the Company's consolidated statements of operations, (ii) service fee costs for capacity at a data center for high performance computing, and other relevant costs.

***Accounts Receivable and Allowance***

The Company's accounts receivable balance consists of amounts due from its data center hosting customers and receivables for demand response services. The Company records accounts receivable at the invoiced amount less an allowance for any potentially uncollectable accounts under the current expected credit loss ("CECL") impairment model and presents the net amount of the financial instrument expected to be collected. The CECL impairment model requires an estimate of expected credit losses, measured over the contractual life of an instrument, that considers forecasts of future economic conditions in addition to information about past events and current conditions. The model also provides a practical expedient, that allows entities to forego developing forecasts of economic conditions. The Company has elected to apply this practical expedient to determine the expected credit losses for current accounts receivable and contract assets, assuming conditions as of the balance sheet date do not change for the remaining life of the asset. Based on this model, the Company considers many factors, including the age of the balance, collection history, and customer creditworthiness. The Company determines the allowance based on historical write-off experience and current exposures identified. The Company reviews its allowance for potentially uncollectible accounts under CECL monthly. Past due balances over 90 days and over a specified amount are reviewed individually for collectability. All other balances are reviewed on a pooled basis by type of receivable. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered. The Company does not have any off balance-sheet credit exposure related to its customers. Bad debts are written off after all collection efforts have ceased.

Allowances for credit losses are recorded as a direct reduction from an asset's amortized cost basis. Credit losses and recoveries are recorded in G*eneral and administrative expenses* in the Consolidated Statements of Operations. For the years ended December 31, 2025 and 2024, the Company had a provision for credit losses of approximately $0 and $760 thousand, respectively. Recoveries of financial assets previously written off are recorded when received. Based on the Company's current and historical collection experience, management recorded an allowance for expected credit losses of approximately $244 thousand and $244 thousand as of December 31, 2025 and December 31, 2024. The Company did not record any recoveries as of December 31, 2025 and December 31, 2024, respectively.

***Employee Receivables***

Certain employees have a receivable due to the Company based on their stock-based awards, in which $15 thousand and $178 thousand was outstanding as of December 31, 2025 and December 31, 2024, respectively. The balance is currently presented as $15 thousand and $82 thousand, respectively within Prepaid expenses and other current assets as of December 31, 2025 and 2024, and $0 and $96 thousand, respectively within Other assets on the financial statements.

***Deposits and Credits on equipment***

As of December 31, 2025 and December 31, 2024, the Company had approximately $1.4 million and $5.1 million, respectively, in deposits and credits on equipment that had not yet been received by the Company as of the year end. Once the Company receives such equipment in the subsequent period, the Company will reclassify such balance into Property, Plant, and Equipment. Included in the December 31, 2024 balance was a credit on equipment of $975 thousand, of which approximately $195 thousand had been used during the year ended December 31, 2025, and the remaining $780 thousand to be used on future purchases for Project Dorothy 2 and Project Kati until September 1, 2025 ("expiration date"). The Company did not execute an order by the expiration date, and no further extension was granted, and as such the credit was forfeited. The Company recorded a loss on the credit deposit of approximately $780 thousand which was included in Loss on sale of fixed assets and credit on equipment deposit on the consolidated financial statements for the year ended December 31, 2025.

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

***Long-Lived Assets***

The Company accounts for impairment or disposal of long-lived assets, which include property, plant, and equipment and also finite-lived intangible assets, in accordance with accounting standards that address the financial accounting and reporting for the impairment or disposal of long-lived assets, specify how impairment will be measured, and how impaired assets will be classified in the Consolidated Financial Statements. On a quarterly basis, the Company analyzes the status of its long-lived assets at each subsidiary for potential impairment. Recoverability of assets to be held and used are measured by a comparison of the carrying amount of an asset to undiscounted future cash flows expected to be generated by the asset. Because the impairment test for long-lived assets held in use is based on estimated undiscounted cash flows, there may be instances where an asset or asset group is not considered impaired, even when its fair value may be less than its carrying value, because the asset or asset group is recoverable based on the cash flows to be generated over the estimated life of the asset or asset group. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. During the year ended December 31, 2025 and 2024, the Company has impaired approximately $12 thousand and $130 thousand, respectively, of property, plant, and equipment, and there was no impairment for the intangible assets for the year ended December 31, 2025 and 2024.

***Cash and Cash Equivalents***

Cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of less than three months.

***Restricted Cash***

Restricted cash relates to cash that is legally restricted as to withdrawal and usage or is being held for a specific purpose and thus not available to the Company for immediate or general business use. As of December 31, 2025, the Company had restricted cash of approximately $12.4 million, of which $4.5 million was classified as current and $7.9 million was classified as non-current. As of December 31, 2024, the Company had restricted cash of approximately $2.6 million, of which $1.1 million was classified as current and $1.5 million was classified as non-current. Currently, the balance in restricted cash relates to a restricted deposit held with a customer that was for less than 12 months. The Company has a long-term restricted cash balance in relation to a collateralized deposits for lines of credit for Project Dorothy 2 and Project Kati.

***Warrant Liability***

Under the guidance in ASC 815, *Derivatives and Hedging* (ASC 815), certain Company warrants associated with the Fourth Amendment described further in Note 8 on February 28, 2024 did not meet the criteria for equity treatment, due to being subject to shareholder approval, the cap containment provision. As such, the warrants were recorded as a liability on the balance sheet at fair value. This valuation was subject to re-measurement at each balance sheet date. With each re-measurement, the warrant valuation was adjusted to fair value, with the change in fair value recognized in the Company's consolidated Statement of Operations. On May 30, 2024, shareholder approval was obtained removing the cap containment provision, and as such, the liability accounting treatment was no longer required. Since all other criteria were met to be treated as equity, the Company adjusted the warrant liability as of the date of shareholder approval and reclassified the balance to equity. As such, the Company accounted for the change in the fair value of the warrant liability as of the date of the shareholder approval (May 30, 2024). In addition, on October 1, 2024, the Company issued 140,000 new penny warrants to the Series B holder in which was subject to shareholder approval that was obtained on November 15, 2024. The Company adjusted the fair value of warrants as of the date of shareholder approval and reclassified the balance to equity, as it no longer required to be treated as a warrant liability as of December 31, 2025 and December 31, 2024.

As discussed in Footnote 8, on June 20, 2024, Cloudco, a subsidiary of Soluna Cloud, entered into a Promissory Note Agreement of $12.5 million with an accredited investor. In addition, on July 12, 2024, CloudCo, Cloud, and the accredited investor noted above entered into a First Amendment to the Note Purchase Agreement (the "June SPA Amendment"). This amendment allows CloudCo to issue additional secured promissory notes totaling $1.25 million to new accredited investors (the "Additional Investors"). In consideration of entering into the promissory note, Cloud issued warrants to the accredited investors. Since the warrants were determined to not be indexed to the Company's own stock under ASC 815-40-15, and since the warrants to be delivered upon exercise are not readily convertible to cash, they do not meet the net settlement criteria within ASC 815-10-15-83. While Soluna Holdings, Inc is publicly traded, the shares provided are specific to Soluna Cloud, Inc, which is a subsidiary of Soluna Holdings, Inc. The shares of Soluna Cloud, Inc are not publicly traded

and therefore the common stock underlying the warrant is not readily convertible to cash. Further evaluation of the Warrants under ASC 815-10 was required to determine if the Warrants meet the definition of a derivative. The warrants are classified as a liability that are required to be adjusted to fair market value. The Company applied a discounted cash flow method in relation to the valuation of Cloud in which assumptions from forecasted projected cash flow data and other key operating assumptions such as working cash flow were used to determine an enterprise value less any current debt in order to determine an equity value for Cloud. The warrants were fair valued in 2024 and written down to $0, and the Company noted that there were no changes for the year ended December 31, 2025.

Certain Company warrants associated with the July 2025 Equity Financing discussed in Note 9 did not meet the criteria for equity treatment. In addition, due to a side letter execution in relation to the Generate Common Warrants as discussed in Note 8, the Generate Common Warrants were reclassified to liability treatment. As such, the warrants were recorded on the balance sheet at fair value. This valuation was subject to re-measurement at each balance sheet date, or when the warrant was exercised. With each re-measurement, the warrant valuation was adjusted to fair value, with the change in fair value recognized in the Company's consolidated statement of operations. The warrants were collectively classified as a Level 3 measurement within the fair value hierarchy due to the use of a valuation model which involves the use of unobservable inputs. As of December 31, 2025, the Series A and Series B warrants associated with the July 2025 Equity Financing warrants had been fully exercised, and on November 4, 2025, shareholder approval to increase authorized share limit and amend the Generate Common Warrants back to the original treatment of equity classification, therefore as of December 31, 2025, the Company's warrant liability outstanding was $0. Please refer to Fair value Measurement note above in relation to the fair value assumptions for the Series A and B Warrant in association with the July 2025 Equity Financing, and in relation to the Generate Common Warrants fair value assumptions.

***Net (loss) Income per Share***

The Company computes basic income per common share by dividing net income by the weighted average number of common shares outstanding during the reporting period. Diluted income per share reflects the potential dilution, if any, computed by dividing income by the combination of dilutive common share equivalents, comprised of shares issuable under outstanding investment rights, warrants and the Company's share-based compensation plans, and the weighted average number of common shares outstanding during the reporting period. Dilutive common share equivalents include the dilutive effect of in-the-money stock options, which are calculated based on the average share price for each period using the treasury stock method. Under the treasury stock method, the exercise price of a stock option and the amount of compensation cost, if any, for future service that the Company has not yet recognized are assumed to be used to repurchase shares in the current period.

***Share-Based Payments***

The Company grants options to purchase its common stock and awards restricted stock to our employees and directors under the Company's equity incentive plans. The benefits provided under these plans are share-based payments and the Company accounts for stock-based awards exchanged for employee service in accordance with the appropriate share-based payment accounting guidance. Stock-based compensation represents the cost related to stock-based awards granted to employees and directors. The Company measures stock-based compensation cost at grant date based on the estimated fair value of the award and recognizes the cost as expense on a straight-line basis in accordance with the vesting of the options (net of estimated forfeitures) over the option's requisite service period. The Company estimates the fair value of stock-based awards on the grant date using a Black-Scholes valuation model. The Company uses the fair value method of accounting with the modified prospective application, which provides for certain changes to the method for valuing share-based compensation. The valuation provisions apply to new awards and to awards that are outstanding on the effective date and subsequently modified. Under the modified prospective application, prior periods are not revised for comparative purposes. Stock-based compensation expense is recorded in the lines titled "Cost of cryptocurrency mining revenue," "Cost of data hosting revenue," and "General and administrative expenses" in the Consolidated Statements of Operations based on the employees' respective functions.

The Company records deferred tax assets for awards that potentially can result in deductions on the Company's income tax returns based on the amount of compensation cost that would be recognized upon issuance of the award and the Company's statutory tax rate. All income tax effects of awards, including excess tax benefits, recognized on stock-based compensation expenses are reflected in the Consolidated Statements of Operations as a component of the provision for income taxes on a prospective basis.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

The determination of the fair value of share-based payment awards on the date of grant using an option-pricing model is affected by the Company's stock price as well as assumptions regarding a number of complex and subjective variables. These variables include the Company's expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, risk-free interest rate, and expected dividends.

Theoretical valuation models and market-based methods are evolving and may result in lower or higher fair value estimates for share-based compensation. The timing, readiness, adoption, general acceptance, reliability, and testing of these methods is uncertain. Sophisticated mathematical models may require voluminous historical information, modeling expertise, financial analyses, correlation analyses, integrated software and databases, consulting fees, customization, and testing for adequacy of internal controls.

For purposes of estimating the fair value of stock options granted using the Black-Scholes model, the Company uses the historical volatility of its stock for the expected volatility assumption input to the Black-Scholes model, consistent with the accounting guidance. The risk-free interest rate is based on the risk-free zero-coupon rate for a period consistent with the expected option term at the time of grant. The expected option term is calculated based on our historical forfeitures and cancellation rates.

The fair value of restricted stock awards is based on the market close price per share on the grant date. The Company expenses the compensation cost of these awards as the restriction period lapses, which is typically a one- to three-year service period to the Company. The shares represented by restricted stock awards are outstanding at the grant date, and the recipients are entitled to voting rights with respect to such shares upon issuance.

***Notes payable***

The Company records notes payable net of any discount or premiums. Discounts and premiums are amortized as interest expense or income over the life of the note in such a way as to result in a constant rate of interest when applied to the amount outstanding at the beginning of any given period.

***Operating segments***

Operating segments are defined as components of an entity for which discrete financial information is available that is regularly reviewed by the chief operating decision maker ("CODM"), which is composed of several members of its senior leadership team, directed by the CEO and CFO. The CODM uses segment operating income (loss) to assess the performance of, manage the operations of, and allocate capital and operational resources to the Company's three reportable segments: Cryptocurrency Mining, Data Center Hosting, and High-Performance Computing Services as described further in Note 16.

***Concentration of Credit Risk***

Financial instruments that subject the Company to concentrations of credit risk principally consist of cash equivalents and trade accounts receivable. The Company's trade accounts receivable are from data hosting revenue with the Company's customers throughout the year. The Company does not require collateral and has not historically experienced significant credit losses related to receivables from individual customers or groups of customers in any particular industry or geographic area. The Company requires that hosting customers make a prepayment of the next month's estimated expenses or make a security deposit to the Company.

The Company has cash deposits in excess of federally insured limits but does not believe them to be at risk. The Company notes that as of December 31, 2025, the cash deposits in excess of federally insured limits was approximately $88.1 million.

***Other Comprehensive Income***

The Company had no other comprehensive income items for the years ended December 31, 2025 and 2024.

***Leases***

*Operating leases*

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets and operating lease liability on our consolidated balance sheets.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU assets also include any lease payments made and excludes lease incentives and initial direct costs incurred. The Company's lease terms may include options to extend or terminate its leases when it is reasonably certain that the Company will exercise those options. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. For real estate leases, the Company accounts for lease components together with non-lease components (e.g., common-area maintenance).

*Finance leases*

Finance leases are included in finance lease ROU assets, finance lease liabilities - current, and finance lease liabilities - noncurrent on the consolidated balance sheets. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Finance lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, the Company generally uses an incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. The finance lease ROU asset may also include any lease payments made and excludes lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Interest expense is determined using the effective interest method. Amortization is recorded on the right-of-use asset on a straight-line basis. Interest and amortization expense are generally presented separately in the consolidated statement of operations.

***Accounting Updates Effective for fiscal year 2025***

Changes to U.S. GAAP are established by the Financial Accounting Standards Board (the "FASB") in the form of accounting standard updates ("ASUs") to the FASB's Accounting Standards Codification ("ASC"). The Company considered the applicability and impact of all ASUs. ASUs not mentioned below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations.

*<u>Improvements to Income Tax Disclosures</u>*

In December 31, 2023, the FASB issued ASU 2023-09, *Income Taxes (Topic 740): Improvements to Income Tax Disclosures* (ASU 2023-09), which requires disclosure of incremental income tax information within the rate reconciliation and expanded disclosures of income taxes paid, among other disclosure requirements. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. See Note 6 in relation to the Company's Income Tax disclosures.

*<u>Stock Compensation</u>*

In March 2024, the FASB issued ASU 2024-01, *Compensation—Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards* ("ASU 2024-01"), to clarify the scope application of profits interest and similar awards by adding illustrative guidance in *ASC 718, Compensation—Stock Compensation* ("ASC 718"). ASU 2024-01 clarifies how to determine whether profits interest and similar awards should be accounted for as a share-based payment arrangement (ASC 718) or as a cash bonus or profit-sharing arrangement *(ASC 710, Compensation—General,* or other guidance*)* and applies to all reporting entities that account for profits interest awards as compensation to employees or non-employees. In addition to adding the illustrative guidance, ASU 2024-01 modified the language in paragraph 718-10-15-3 to improve its clarity and operability without changing the guidance. ASU 2024-01 is effective for fiscal years beginning after December 15, 2024, and interim periods within fiscal years beginning after December 15, 2025. Early adoption is permitted. The amendments should be applied either retrospectively to all prior periods presented in the financial statements, or prospectively to profits interests and similar awards granted or modified on or after the adoption date. The Company notes that this ASU did not have an impact on the consolidated financial statements for the year ended December 31, 2025. If any new awards are issued in the future, the Company will evaluate the scope application of this ASU.

***Accounting Updates Not Yet Effective***

*<u>Improvements to Comprehensive Income- Expense Disaggregation</u>*

In November 2024, the FASB issued ASU 2024-03, *Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40)* ("ASU 2024-03"). ASU 2024-03 requires, in the notes to the financial statements, disclosures of specified information about certain costs and expenses specified in the updated guidance. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is evaluating the impact the updated guidance will have on its disclosures.

*<u>Debt with Conversion and Other Options</u>*

In November 2024, the Financial Accounting Standards Board ("FASB") issued ASU No. 2024-04, *Debt - Debt with Conversion and Other Options* (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments. ASU 2024-04 clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion to improve relevance and consistency. The new standard is effective for the Company for its annual periods beginning after December 15, 2025 and interim periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact of adopting the standard.

In connection with the strategic contract pipeline acquired in the Soluna Callisto acquisition as further discussed in Note 5, ASC 740-10-25-51 requires the recognition of a deferred tax impact of acquiring an asset in a transaction that is not a business combination when the amount paid exceeds the tax basis on the acquisition date. As such, the Company is required to adjust the value of the strategic contract pipeline by approximately $10.9 million and this amount will be amortized over the life of the asset.

***Valuation Allowance:***

The Company believes that the accounting estimate for the valuation of deferred tax assets is a critical accounting estimate because judgment is required in assessing the likely future tax consequences of events that have been recognized in our financial statements or tax returns. The Company based the estimate of deferred tax assets and liabilities on current tax laws and rates and, in certain cases, business plans and other expectations about future outcomes.

As a result of its assessment in 2025, the Company increased its valuation allowance against its deferred tax assets. The increase in the valuation allowance caused incremental tax expense of $3.3 million to be recognized in 2025. The increase of the valuation allowance was based upon the uncertainty surrounding the Company's projected future taxable income, causing the Company to evaluate what portion of the Company's deferred tax assets it believes are more likely than not to be realized. The Company has determined that it will not generate sufficient levels of pre-tax earnings in the future to realize the deferred tax assets relating to net operating loss carryforwards and research and development credit carryforwards recorded on the balance sheet as of December 31, 2025. Taking into consideration existing levels of permanent differences, non-deductible expenses and the reversal of significant temporary differences, the Company has determined that all other deferred tax assets recorded on the balance sheet as of December 31, 2025, will not be fully realized.

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

The valuation allowance on December 31, 2025 and 2024 was $41.8 million and $38.5 million, respectively. Activity in the valuation allowance for deferred tax assets is as follows as of December 31:

***Net operating losses:***

As of December 31, 2025, the Company has unused Federal net operating loss carryforwards of approximately $171.0 million after reducing the total by $14.2 million which expired in 2025. Of what is remaining, $33.9 million will begin to expire in 2026 and the remainder being carried forward indefinitely.

The Company's and/or its subsidiaries' ability to utilize their net operating loss carryforwards may be significantly limited by Section 382 of the IRC of 1986, as amended, if the Company or any of its subsidiaries undergoes an "ownership change" as a result of changes in the ownership of the Company's or its subsidiaries' outstanding stock pursuant to the exercise of the warrants or otherwise.

***Unrecognized tax benefits:***

The Company has unrecognized tax benefits of $0 and $0 thousand as of December 31, 2025 and 2024, respectively.

Additionally, the Company does not have uncertain tax positions that it expects will increase or decrease within twelve months of this reporting date. The Company recognizes interest and penalties related to uncertain tax positions as a component of tax expense. The Company did not recognize any interest or penalties in 2025 or 2024.

The Company files income tax returns, including returns for its subsidiaries, with federal and state jurisdictions. The Company is no longer subject to IRS or state examinations for any periods prior to 2021, although carryforward attributes that were generated prior to 2023 may still be adjusted upon examination by the IRS if they either have been or will be used in a future period.

*Contract liability*

In June 2024, Soluna AL Cloudco, LLC ("CloudCo"), a subsidiary of Soluna Cloud, entered into an agreement (the "HPE Agreement") with Hewlett Packard Enterprise Company ("HPE"), with an initial pre-payment of $10.3 million and a total commitment of $34.0 million over a 36-month period. On March 24, 2025, CloudCo notified HPE of its termination of the HPE Agreement and, on March 26, 2025, HPE notified CloudCo of its termination of the HPE Agreement for cause, effective immediately, due to CloudCo's material breach of its payment obligations that remained uncured for more than thirty (30) days. The HPE Agreement provided the Company access to datacenter and cloud services for AI and supercomputing applications utilizing NVIDIA H100 GPUs. In accordance with the terms of the HPE Agreement, CloudCo was required to pay all of the unpaid fees that were payable over the entire term of the HPE Agreement. In accordance with the terms of the HPE Agreement, upon a termination for cause by HPE, CloudCo must pay HPE the remaining payment stream under the term of the HPE Agreement, including all upfront payments and monthly charges, plus any fees incurred for the terminated Services (as defined in the HPE Agreement). As of December 31, 2024, the Company reduced its prepaid assets and other long-term assets by approximately $8.6 million, increased termination liability by approximately $20.0 million and recorded a loss on contract of approximately $28.6 million to account for the termination of the contract and CloudCo's contractual payments. As of December 31, 2025, the outstanding contract liability was approximately $19.3 million.

\*Due to event of default- the entire NYDIG Financing became current, see note below.

On December 30, 2021, Soluna MC Borrowing 2021-1 LLC (the "Borrower"), a subsidiary of Soluna MC, LLC, a subsidiary of Soluna Digital, a subsidiary of the Company, entered into a Master Equipment Finance Agreement (the "Master Agreement") with NYDIG ABL LLC ("NYDIG") as lender, servicer and collateral agent (the "NYDIG facility"). The Master Agreement provided for up to approximately $14.4 million in total equipment financing (the "NYDIG Loans").

On January 14, 2022, the Borrower effected an initial drawdown under the Master Agreement in the aggregate principal amount of approximately $4.6 million that bore interest at 14% and was to be repaid over 24 months. On January 26, 2022, the Borrower had a subsequent drawdown of $9.8 million. Soluna MC LLC, the Borrower's parent, provided a guaranty, and the Borrower pledged its assets, including a certain digital asset accounts, as collateral for the NYDIG Loans.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

On December 20, 2022, after the Borrower defaulted on the NYDIG Loans, NYDIG issued a Notice of Acceleration and Repossession under the Master Agreement. The obligations under this facility were ring-fenced to the Borrower and its direct parent, Soluna MC LLC. The Company itself was not a guarantor of the NYDIG Loans.

On February 23, 2023, NYDIG foreclosed on the collateral, repossessing assets valued at approximately $3.4 million, of which approximately $560 thousand was first used to pay off accrued interest and penalties. On December 7, 2023, NYDIG filed its Motion for Summary Judgment seeking entry of a judgment against Soluna in the approximate amount of $10.3 million for unpaid principal, interest, and penalties. Following court proceedings, the parties agreed that the total outstanding loan principal balance would be approximately $9.2 million (the "Agreed Judgment Amount").

On September 29, 2025, the Borrower, Soluna MC, LLC (the "Guarantor" and together with Borrower, the "NYDIG Defendants") and NYDIG executed a Settlement Agreement to fully resolve the Agreed Judgment Amount and all related claims. Under the Settlement Agreement, the NYDIG Defendants agreed to make certain settlement payments to NYDIG, and in return, NYDIG and its affiliates released the NYDIG Defendants and its related parties from all claims related to the NYDIG Loans.

As a result, the Company recorded a gain on extinguishment of debt for the remaining principal, accrued interest, and penalties. As of December 31, 2025, the settlement amount had been paid, and no further obligations remain as of the date of this filing.

On June 20, 2024, pursuant to the terms and subject to the conditions of a Note Purchase Agreement (the "June SPA" or "Green Cloud secured note") by and among (i) CloudCo, a Delaware limited liability company and indirect wholly owned subsidiary of the Company, (ii) Soluna Cloud, a Nevada corporation, indirect wholly owned subsidiary of the Company, and parent of CloudCo, (iii) the Company and (iv) the accredited investor named therein (the "Investor", and collectively the "Note Parties"), CloudCo issued to the Investor a secured promissory note in a principal amount equal to $12.5 million (the "Note"). The Note accrues interest at a rate 9.0% per annum, subject to adjustment upon an event of default. The Note matures on June 20, 2027. CloudCo's obligations under the Note will be secured by all or substantially all of CloudCo's assets, including pursuant to a security agreement to be executed and delivered by CloudCo in favor of the Investor (the "CloudCo Security Agreement", and together with the June SPA and the Note, the "CloudCo Agreements").

As further inducement for the Investor to purchase the Note, Soluna Cloud issued to the Investor a warrant (the "Warrant") exercisable within three years from June 20, 2024 for a number of shares of common stock of Soluna Cloud equal to the sum of (a) 12.5% of Soluna Cloud's issued and outstanding common stock as of the date of the Warrant divided by 0.875, plus (b) the percentage of each Qualified Issuance (as defined below) divided by 0.875. For purposes of the Warrant, "Qualified Issuance" means (y) each issuance of common stock of Soluna Cloud during the period commencing on the day after the date of the Warrant and ending on the earlier to occur of (i) the conclusion of up to an additional $112.5 million of capital raised, whether in the form of debt, equity, mixed or otherwise, by Soluna Cloud and its subsidiaries and (ii) December 31, 2025 and (z) the number of shares of common stock of Soluna Cloud issuable upon the exercise or conversion of any convertible securities of CloudCo issued during such period (other than certain issuances pursuant to CloudCo's equity compensation plans). On June 20, 2024, the Company determined that the warrant should be treated as a warrant liability and based on valuation, the Company booked a warrant liability of approximately $314 thousand and a related debt discount which will be amortized over the life of the loan. Further evaluation of the Warrants under ASC

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

815-10 was required to determine if the warrants meet the definition of a derivative. The warrants are classified as a liability that are required to be adjusted to fair market value. The Company applied a discounted cash flow method in relation to the valuation of Cloud in which assumptions from forecasted projected cash flow data and other key operating assumptions such as working cash flow were used to determine an enterprise value less any current debt in order to determine an equity value for Cloud. As of December 31, 2025 and December 31, 2024, the warrants were fair valued, and deemed to not have any further value, as such the Company wrote down the liability balance to $0.

For the years ended December 31, 2025 and 2024, the Company incurred approximately $1.3 million and $847 thousand in interest expense in relation to the Green Cloud secured note.

***June SPA Modification to Green Cloud secured note***

On March 23, 2025, the Note Parties entered into a Modification Agreement (the "Modification Agreement") to, among other things:

(i) &nbsp;&nbsp;&nbsp;&nbsp;provide for the deposit of 1,000,000 shares (the "Escrow Shares") of the Company's common stock, par value $0.001 per share (the "Common Stock"), into an escrow account maintained by Northland Securities, Inc., pursuant to an escrow agreement (as further described below),

(ii) &nbsp;&nbsp;&nbsp;&nbsp;provide for the issuance to the Investor of a warrant to purchase shares of Common Stock upon the release by the Investor of its lien on the property of the Company,

(iii) &nbsp;&nbsp;&nbsp;&nbsp;amend the payment schedule of the Note to provide (a) for each of the six scheduled payments occurring after the earlier of the effectiveness of a registration statement for the resale of the Escrow Shares and the Conversion Shares (as defined below) or the date that the Escrow Shares and the Conversion Shares may be sold pursuant to Rule 144 under the Securities Act of 1933, as amended (the "Securities Act"), without any information requirements, the amount of principal and interest payable on such date shall be reduced by 50% (the aggregate amount of the six months of such reductions, the "Specified Amount") and (b) if the aggregate amount of payments on the Amended Note applied from the proceeds of the sale of the Escrow Shares on or prior to the last six scheduled payments is less than the Specified Amount (such difference, the "Make Whole Amount"), than the amount of each of the remaining scheduled payments shall be increased by an amount equal to the Make Whole Amount divided by the number of remaining scheduled payments,

(iv)&nbsp;&nbsp;&nbsp;&nbsp; modify the Note such that the Note is now convertible into up to 2,500,000 shares (the "Conversion Shares") of Common Stock based on a conversion price of $5.00,

(v) &nbsp;&nbsp;&nbsp;&nbsp;amend the Note to provide that the Company will be a direct co-obligor with CloudCo under the Note, and

(vi)&nbsp;&nbsp;&nbsp;&nbsp;amend the SPA to allow the Company to organize or incorporate any subsidiary, over which the Company shall have voting or beneficial control, which is being formed with the intent to engage in a business or line of business substantially similar to that of Soluna Cloud or the Company, without first paying all of the principal and interest due under the Note and without first obtaining Investor's prior written consent (collectively, the "June SPA Modification").

The joint-and-several liability arrangement is between the Company and CloudCo. While no written agreement has been created to establish the amount that each entity agrees to pay under the obligation, the nature of the relationship is such that the Company has taken a significant role in the economics of the Notes. The Company expects to make any necessary payments on behalf of CloudCo in order to prevent default on the Notes because the Investor has a lien on all property and assets of the Company in connection with the Notes. Based on quantitative analysis performed by the Company, it was determined that the terms of the debt instrument before and after the June SPA Modification were not substantially different. Accordingly, the June SPA Modification is accounted for as a debt modification.

Subsequently, the Company and the Investor mutually agreed that the 1,000,000 Escrow Shares would instead be issued directly to the Investor and, on April 29, 2025, the Company issued 1,000,000 shares of common stock to the Investor. When the Investor sells the 1,000,000 shares in the open market, the net proceeds from dispositions of the Escrow Shares (i) at a price of up to $4.00 per share shall be applied to reduce the outstanding principal balance of the Note and (ii) at a price greater than $4.00 per share shall be applied first to reduce the outstanding principal balance of the Note in an amount equal to $4.00 per share of Common Stock and then to the Investor. The Investor has until March 31, 2026 (the "Sales Period") to sell the 1,000,000 shares to reduce the outstanding principal balance, or would have to return the shares. As of the date of these consolidated financial statements, the Company and Investor are looking to extend the Sales Period to April 30, 2026.

\* On March 14, 2025, the Company satisfied the assignment and assumption agreement, as such a gain on extinguishment was recorded.

On July 12, 2024, the Company, CloudCo, Soluna Cloud, and the Investor entered into a First Amendment to the Note Purchase Agreement (the "June SPA Amendment"). This amendment allows CloudCo to issue additional secured promissory notes totaling $1.25 million (the "Additional Notes") to new accredited investors (the "Additional Investors"). These Additional Notes are subject to the same terms and conditions as the June SPA financing.

To further incentivize the Additional Investors, Soluna Cloud issued warrants (the "Cloud Additional Warrants") to each Additional Investor. These Cloud Additional Warrants are exercisable within three years from the effective date of the June SPA Amendment. They allow the purchase of a number of shares of Soluna Cloud common stock equal to 1.25% of Soluna Cloud's issued and outstanding common stock as of the Cloud Additional Warrant date, divided by 0.9875, plus 1.25% of each Qualified Issuance, divided by 0.9875.

A "Qualified Issuance" includes any issuance of common stock by Soluna Cloud from the day after the date of issuance of the Cloud Additional Warrant until the earlier of raising an additional $111.25 million or December 31, 2024, as well as shares issuable upon exercise or conversion of convertible securities issued during this period, excluding certain equity compensation plan issuances.

On October 1, 2024, CloudCo, Soluna Cloud and the Company entered into assignment and assumption agreements (the "Assignment Agreements") with the Additional Investors with respect to an aggregate of $1.25 million of notes issued by CloudCo. Pursuant to the Assignment Agreements, the Company will be able to purchase such notes for a purchase price of $750 thousand, or 60% of face value. The assignment and assumption will be effective once all conditions of the agreement are met including fulfilling the purchase price.

On March 14, 2025, the Company fulfilled the purchase obligations, and assumed the Additional Notes through payment of $750 thousand through principal and 50% interest payments and use of 20% SEPA funds. Effectively, the remaining debt assignment was assumed by Soluna Holdings, Inc. and was recorded as an intercompany debt obligation that was eliminated on the Company's consolidated financial statements as of December 31, 2025. The Company recorded a gain on extinguishment of the July 2024 Additional Secured Notes of approximately $551 thousand for the year ended December 31, 2025. For the years ending December 31, 2025 and 2024, the Company incurred approximately $33 thousand and $54 thousand in interest expense in relation to the July Additional Secured Note.

On March 12, 2025, Soluna SW LLC (the "SW Borrower"), a Delaware limited liability company and subsidiary of Soluna SW Holdings LLC ("SW Holdings", and together with the SW Borrower, the "SW Loan Parties"), a subsidiary of SDI, a Nevada corporation and wholly owned subsidiary of Company, entered into a Loan Agreement (the "Galaxy Loan Agreement") with SW Holdings and Galaxy Digital LLC (the "Lender").

The Galaxy Loan Agreement provides for a term loan facility in the principal amount of $5.0 million(the "Term Loan Facility"). The Term Loan Facility bears interest at a rate of 15% per annum, subject to an increase of 5.0% (for a total of 20.0%) if an Event of Default (as defined in the Galaxy Loan Agreement) has occurred and is continuing. The Term Loan Facility matures on March 12, 2030 and includes scheduled payments over a five-year term. For the year ended December 31, 2025, the Company incurred approximately $694 thousand in interest expense in relation to the Term Loan Facility, which includes interest paid on the note and amortization of deferred financing costs.

The SW Borrower may voluntarily prepay all or part of the Term Loan Facility at any time together with accrued and unpaid interest on the principal amount to be prepaid up to the date of prepayment. The SW Borrower shall prepay all or part of the Term Loan Facility with 100% of the Net Cash Proceeds (as defined therein) received upon the occurrence of (i) an Asset Sale or Casualty Event (each as defined therein), (ii) an Equity Issuance (as defined therein), (iii) an issuance or incurrence of Indebtedness (as defined therein), or (iv) an Extraordinary Receipt (as defined therein), each subject to certain exceptions. In addition, certain principal payments are subject to the payment of a premium amount equal to 50% of the remaining amount of interest payable on such principal amount through the scheduled maturity date, if paid on or prior to the 30-month anniversary of the closing date, and 25% of the remaining amount of interest payable on such principal amount through the scheduled maturity date, if paid after the 30-month anniversary of the closing date.

The Galaxy Loan Agreement includes certain restrictions (subject to certain exceptions outlined in the Galaxy Loan Agreement) on the ability of the SW Loan Parties and their subsidiaries to undertake certain activities, including to incur indebtedness and liens, enter into sale or lease-back transactions, merge or consolidate with other entities, dispose or transfer their assets, pay dividends or make distributions, make investments, make Restricted Payments (as defined therein), enter into burdensome agreements or transact with affiliates. In addition, the SW Loan Parties are subject to three financial covenants – a minimum debt service coverage ratio, a minimum current ratio, and cash in customer deposit account must equal or be greater than related customer liabilities. As of the date of these consolidated financial statements, the Company is in compliance with all covenants in relation to the Galaxy Loan Agreement.

Proceeds of the Term Loan Facility will be used to issue a distribution to SW Holdings, the proceeds of which may be used to make a distribution to SDI.

In connection with the Galaxy Loan Agreement, on March 12, 2025, the SW Loan Parties and the Lender entered into a security agreement to secure the obligations under the Term Loan Facility by a lien on substantially all the assets and properties of SW Borrower and SW Holdings, subject to certain exceptions. The SW Borrower is the owner and operator of the Company's Project Sophie data center.

In connection with the Galaxy Loan Agreement, on March 12, 2025, SDI and the Lender entered into a Limited Guarantee Agreement pursuant to which SDI guarantees the Loss Liabilities (as defined therein) and, after the occurrence of a Recourse Trigger Event (as defined therein), the obligations under the Loan Agreement.

On September 12, 2025, the Company caused its subsidiaries Soluna DVSL ComputeCo, LLC ("Dorothy 1A Borrower"), Soluna DVSL II ComputeCo, LLC ("Dorothy 2 Borrower"), and Soluna KK I ComputeCo, LLC ("Tranche B Borrower" and collectively with Dorothy 1A Borrower and Dorothy 2 Borrower, the "Borrowers") to enter into a Credit and Guaranty Agreement (the "Credit Agreement") with Generate Lending, LLC, as administrative agent and collateral agent (the "Agent"), and Generate Strategic Credit Master Fund I-A, L.P. (the "Lender"). The Credit Agreement provides for senior secured term loan commitments in an aggregate principal amount of up to $35.5 million, comprised of (i) Tranche A-1 ($5.5 million), (ii) Tranche A-3 ($11.5 million), and (iii) Tranche B ($18.5 million). In addition, the Credit Agreement permits the Borrowers to request one or more Additional Tranche Loan Commitments (as defined in the Credit Agreement), in the aggregate amount of up to $64.5 million, subject to the approval of the Lender and the Agent, for project-level financing of eligible projects. As of December 31, 2025, the Borrowers borrowed approximately $17.0 million under the Credit Agreement, comprised of Tranche A-1 loans and Tranche A-3 loans. The Company can draw upon Tranche B from September 12, 2025 until October 31, 2026, subject to the conditions set forth in the Credit Agreement. The maturity date for the Tranche A and Tranche B loans is the earlier of (i) payment of outstanding principal, interest, and fees and (ii) September 12, 2030. Additional Tranche Loan Commitments will have maturity dates as set forth in their respective amendments to the Credit Agreement. For the year ended December 31, 2025, interest expense was approximately $1.1 million.

Proceeds from the Generate Credit Agreement will be used to finance, refinance, develop and construct the Company's Dorothy 1A, Dorothy 2 and Kati data center projects, fund a debt service reserve account, and pay fees and expenses. The loans bear interest at a variable rate based on either ABR or Term SOFR, as set forth in the Generate Credit Agreement. The applicable interest rate for SOFR loans is equal to Term SOFR plus a margin of 10.0% per annum, and for ABR loans is equal to the ABR plus a margin of 9.0% per annum. The Generate Credit Agreement provides for a SOFR rate floor of 3.5% per annum. The Borrowers are required to pay a commitment fee of 1.0% per annum on undrawn amounts of the Tranche B Loan Commitments and any Additional Tranche Loan Commitments. During the continuance of an event of default, a default rate applies equal to the otherwise applicable rate plus 2.0% per annum.

The loans are subject to scheduled amortization, fees and prepayment premiums which will be paid through excess cash sweeps. The classification of the outstanding principal balance of the Generate loan balance into current and non-current liabilities is contingent upon management's estimate of the future application of mandatory debt repayments. The Credit Agreement contains a mandatory prepayment provision, or "cash sweep," requiring a percentage of free cash flow, as defined in the Credit Agreement, to be applied to principal reduction on a periodic basis. The amount expected to be prepaid via this sweep mechanism during the next twelve months is classified as current debt. This classification relies on management's internal cash flow forecast, which incorporates assumptions regarding future operating performance, capital expenditures, and working capital needs. Assumptions include market volatility risks, which are inherently unpredictable. Because the classification is dependent upon these management estimates, the actual amount of debt paid down through the cash sweep mechanism may differ materially from the amounts classified as current liabilities. The obligations are guaranteed by certain Company subsidiaries and secured by first-priority liens on substantially all assets of the Borrowers and guarantors, including pledges of equity interests, security interests in deposit and other collateral accounts (subject to control agreements), and mortgages/deeds of trust on the relevant project sites.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

The Credit Agreement contains customary representations and warranties, affirmative and negative covenants, and events of default for financings of this type. Events of default under the Credit Agreement include, among other things, non-payment of principal, interest or fees, inaccuracy of representations and warranties, breach of covenants, cross-default to certain material indebtedness, bankruptcy and insolvency, and change of control. Upon the occurrence and during the continuance of an event of default, the lenders may declare all outstanding principal and accrued but unpaid interest under the Credit Agreement immediately due and payable and may exercise the other rights and remedies provided under the Credit Agreement and related loan documents. Negative covenants in the Credit Agreement include, among other things, restrictions on the Borrowers and guarantors with respect to incurring additional indebtedness, creating liens on assets, selling assets or making fundamental changes, making restricted payments, entering into affiliate transactions, and using loan proceeds for unauthorized purposes. The Credit Agreement also restricts investments, capital expenditures, and speculative transactions, and requires that all deposit and securities accounts be subject to control agreements. Financial covenants require (i) a minimum trailing Debt Service Coverage Ratio of 1.60:1.00 and (ii) a minimum Forward Contracted Debt Service Coverage Ratio of 1.20:1.00, in each case as further described in the Credit Agreement. The facility also includes customary mandatory prepayment provisions. As of the date of these consolidated financial statements, the Company received a waiver and is in compliance with all covenants in relation to the Generate Credit Agreement.

Pursuant to the Credit Agreement, the Company issued to Generate Strategic Credit Master Fund I-B, L.P., an affiliate of the Lender and the Agent (the "Holder"), in a private placement (the "Private Placement"): (i) a pre-funded warrant (the "Generate Pre-Funded Warrant") to purchase up to 2,000,000 shares of common stock at an exercise price of $0.0001, terminating on the five year anniversary, September 12, 2030; and (ii) a common warrant (the "Generate Common Warrant" and, together with the Generate Pre-Funded Warrant, the "Generate Warrants") to purchase up to 2,000,000 shares of common stock at an exercise price of $1.18 terminating on the five year anniversary, September 12, 2030. The Holder does not have the right to exercise any portion of the Generate Pre-Funded Warrant or Generate Common Warrant, if the Holder, would beneficially own in excess of 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to such exercise.

***Equipment Loan Agreement***

On May 16, 2024, SDI SL Borrowing – 1, LLC, an affiliate of Soluna Holdings, Inc. (the "Borrower") entered into a loan agreement (the "Equipment Loan Agreement" or the "Loan") with Soluna2 SLC Fund II Project Holdco LLC (the "Lender", and collectively, the "Parties"). The Equipment Loan Agreement provides for the Company to borrow, from time to time, up to $1.0 million, and further amended on February 28, 2025 to $4.0 million to be used to purchase necessary equipment for the progression of Project Dorothy 2 and Project Kati. Any loans made under the Equipment Loan Agreement have a maturity date of May 16, 2027 and will bear interest at a rate of 15% per annum. The Equipment Loan Agreement includes customary covenants for loans of this nature, as well as a multiple on invested capital ("MOIC") provision, which requires the Company to pay, in addition to principal and interest, an amount equal to the difference of (i) the greater of (a) the principal amount of the Loan being repaid *plus* all interest previously paid or simultaneously being paid to Lender in respect of such principal of the Loan, and (b) the principal amount of the Loan being repaid multiplied by three (3.0), *minus* (ii) the sum of the principal amount of the Loan being repaid *plus* all interest previously paid or simultaneously being paid to Lender in respect of such principal of the Loan.

On May 17, 2024, the Borrower drew down $720 thousand of the equipment loan with the Lender. On July 22, 2024, the Borrower satisfied and repaid the borrowing amount in full by issuing the Investor Class B Membership Interests in the Dorothy 2 project valued at three times the borrowing amount (i.e., $2.16 million). The redemption of debt through equity created approximately a $1.4 million loss on debt extinguishment for the year ended December 31, 2024.

On March 21, 2025, the SDI Borrower drew down $250 thousand of the Loan with the Lender, in relation to Project Kati. In addition, on June 11, 2025 and July 16, 2025, the SDI Borrower drew down an additional $269.2 thousand and $291.4 thousand, respectively of the Loan with the Lender, in relation to Project Kati. The total amount of equipment loans of $810.6 thousand was outstanding prior to the assignment of equipment and payoff of the loan. The SDI Borrower shall repay the Loans under these Borrowing Requests with a different MOIC Payment than as defined in the Equipment Loan Agreement. The MOIC Payment for these Borrowing Requests only, shall be an amount equal to the difference of (i) the greater of (a) the principal amount of the Loan being repaid plus all interest previously paid or simultaneously being paid to Lender in respect of such principal of the Loan, and (b) the principal amount of the Loan being repaid multiplied by three and three tenths (3.3), minus (ii) the sum of the principal amount of the Loan being repaid plus all interest previously paid or simultaneously being paid to Lender in respect of such principal of the Loan. As of the date prior to the payoff, the

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

Company had approximately $180.6 thousand in Accrued interest payable in relation to the MOIC and 15% interest accruing on the Loan that was outstanding that was written off.

On August 1, 2025, the SDI Borrower satisfied and repaid the borrowing amount in full by issuing Spring Lane Capital ("SLC") Class B Membership Interests in Soluna KKSL JVCo LLC ("Kati") project for 3.3 times the membership units ($810.6 thousand payoff equal to fair value of approximately $2.7 million for Class B membership units issued to SLC), as part of the contribution agreement between the Parties. Through initial contributions of $810.6 thousand (debt repayment), SLC received 2,675 Class B Membership units, which constituted a 100% initial Class B membership interest of Kati. The redemption of debt through equity created approximately a $1.7 million loss on debt extinguishment for the year ended December 31, 2025.

*Land Purchase Loan*

On October 1, 2025, the Borrower, and Soluna2 Kati Project Holdco LLC ("Kati Lender"), entered into a borrowing request of $1.075 million to cover the purchase of land to support construction of Project Kati Phase 2 under the terms of the Equipment Loan Agreement. For the land purchase, per the terms of a letter agreement between Spring Lane and the Company, the Company is allowed to apply 1.00 MOIC and interest free obligation on the loan in relation to the land purchase.

Per ASC 835-30-S45-1, debt issuance costs related to line of credits should be recorded as an asset and amortized over the life of the line of credit agreement. As such, the Company recorded $64 thousand and $53 thousand within Prepaid expenses and other current assets as of December 31, 2025 and 2024 and $25 thousand and $75 thousand within Other assets on the consolidated balance sheet as of December 31, 2025 and 2024, of which $62 thousand and $35 thousand has been amortized and recorded within Interest Expense for the years ended December 31, 2025 and 2024.

On May 9, 2023, DVCC and Navitas West Texas Investments SPV, LLC entered into a 2-year Loan Agreement ("Term Loan") for $2,050,000. As of December 31, 2025, the Company has paid the remaining outstanding balance of approximately $137 thousand, therefore fulfilling its debt obligation with Navitas. Interest expense related to the Navitas Term Loan for the years ended December 31, 2025 and 2024 was approximately $2 thousand and $138 thousand, respectively, which includes interest associated with the debt issuance costs.

***Convertible Notes***

On October 25, 2021, pursuant to a Securities Purchase Agreement (the "October SPA"), the Company issued to certain accredited investors (the "Noteholders") (i) secured convertible notes in an aggregate principal amount of $16.3 million for an aggregate purchase price of $15 million (collectively, the "October Secured Notes"), which were, subject to certain conditions, convertible at any time by the investors, into an aggregate of 1,776,073 shares of the Company's common stock, at a price per share of $9.18 and (ii) Class A, Class B and Class C common stock purchase warrants (collectively, the "October Warrants") to purchase up to an aggregate of 1,776,073 shares of common stock, at an initial exercise price of $12.50, $15 and $18 per share, respectively. The October Warrants are legally detachable and can be separately exercised immediately for five years upon issuance, subject to applicable Nasdaq rules.

On July 19, 2022 and on September 13, 2022, the Company entered into an Addendum and Addendum Amendment which adjusted the terms such as maturity date, conversion prices, and the issuance of new warrants to the Noteholders. Pursuant

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

to the Addendum and Addendum Amendment, the Company evaluated whether the new addendums qualified as debt modification or debt extinguishment. Based on ASC 470, Debt, the Company determined the Addendum and Addendum Amendment to fall under Debt Extinguishment treatment and the Company would be required to record the new debt at fair value, and in turn write off the existing debt on the books.

Following the debt extinguishment on July 19, 2022 as noted above, the Convertible Notes have been accounted for under the fair value method on a recurring basis upon issuance (e.g., upon execution of the Addendum) per guidance within ASC 480, and at each subsequent reporting period, with changes in fair value reported in earnings. See below for rollforward of the fair value of the convertible debt:

---

On February 28, 2024, the Company and the Noteholders entered into a Fourth Amendment Agreement to amend the Notes, SPA and related agreements to facilitate future financings by the Company. In addition, the Company was permitted to unilaterally extend the maturity date of the Notes for two 3-Month extensions if prior to the then in effect maturity date the Company gives notice to the Noteholders and increases the principal amount of the Notes on the date of each such extension by two percent (2%) the principal amount of the Notes outstanding on the date of such extension.

In consideration of the foregoing, the Company:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reduced the conversion price of the Notes to $3.78 per share;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Noteholders received an aggregate of 850,000 three year warrants exercisable at $0.01 per share;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An aggregate of 320,005 warrants held by the Noteholders had the exercise price reduced to $3.78 per share (the "$3.78 Warrants"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An aggregate of 478,951 warrants held by the Noteholders had the exercise price reduced to $6.00 per share (the "$6.00 Repriced Warrants"). For every one $6.00 Repriced Warrant exercised by a Purchaser, such Purchaser shall receive 1.36 new five-year warrants with an exercise price of $0.01, 1.6 new five-year warrants with an exercise price of $4.20, and 1.6 new five-year warrants with an exercise price of $5.70.

In June 2024, pursuant to the Fourth Amendment Agreement, the Company exercised its right to extend the maturity date of the Notes for an additional six months, or until January 24, 2025, to enable the Company to continue to pursue its significant project development opportunities for Soluna Cloud, Dorothy 2, and other projects. The extension of the notes caused an increase in the convertible note balance of approximately $325 thousand and the extension fee was recorded within Other Expense, net for the year ended December 31, 2024.

The effect of the additional penny warrants, $3.78 warrants, and the $6.00 repriced warrants including additional warrants if exercised with the Noteholders, created a loss on debt extinguishment of approximately $5.8 million due to the fair value associated as of February 28, 2024. Such amounts were recorded as a loss on debt extinguishment and affected the Company's warrant liability and additional paid in capital balance account. Due to the requirement of the shareholder approval associated with the Fourth Amendment, the warrants associated were initially treated as a liability. In addition, a warrant revaluation was done on March 31, 2024, which created a gain on revaluation associated with the warrant liability of approximately $1.5 million. On May 30, 2024, shareholder approval was obtained removing the cap containment provision for the warrants, and as such, the liability accounting treatment was no longer required. Since all other criteria were met to be treated as equity, the Company adjusted the warrant liability as of the date of shareholder approval and

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

reclassified balance to equity. As such, the Company accounted for the change in the fair value of the warrant liability as of the date of the shareholder approval (May 30, 2024), in connection with its loss on revaluation of the warrant of approximately $1.6 million.

Pursuant to additional agreements with holders of another 51,618 outstanding warrants, similar adjustments with those warrants, resulted in a total adjustment to 530,569 warrants. As the 51,618 warrants were not with the Noteholders, the treatment of $6.00 repriced warrants was recorded as a deemed dividend and adjusted the Company's earnings per share calculation noted in Footnote 11 for the year ended December 31, 2025. The fair value associated with the 51,618 warrants with non-Noteholders totaled approximately $386 thousand. On May 17, 2024, the Company permitted the holders of the Company's Amended Class C Warrants, previously exercisable at $6 per share, to exercise such warrants at a reduced exercise price of $4 per share, provided that each such holder exercised at least 61.83% of their Amended Class C Warrants by the close of business on May 17, 2024. The Company also agreed to reduce the exercise price on all remaining Amended Class C Warrants. The adjustment in the exercise price, resulted in an additional deemed dividend which amounted to approximately $66 thousand for the year ended December 31, 2024.

For the year ended December 31, 2024, 529,161 of the Amended Class C warrants have been exercised by both the Noteholders and non-Noteholders, resulting in the issuance of 719,658 shares of $0.01 warrants, 846,657 shares of $4.20 warrants, and 846,657 shares of $5.70 warrants.

As discussed in Footnote 9, the Company entered into a SEPA with YA II PN, LTD on August 12, 2024. Access to the SEPA was subject to a number of conditions precedent including, but not limited to, various consents from the Company's Note Holders. On October 1, 2024, the Noteholders entered into a Consent, Waiver, and Mutual Release Agreement (the "Master Consent") which provides the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• consent to the Company's entry into the SEPA;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• waiver of any rights of first refusal or participation rights in connection with the SEPA;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• standstill of the rights to exercise certain $0.01 warrants pursuant to the SPA;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the right to prepay the convertible notes with a 20% premium;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• termination of the SPA and related agreements upon the full payoff of the convertible notes; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mutual limited release of claims between the Noteholders and the Company.

In return for these consents, the Company agreed to pay a $750 thousand waiver fee and to prepay to the remaining Note Holders the 20% premium for the prepayment of the Notes of approximately $625 thousand. Such amounts were recorded as within Other Expense, net within the Consolidated Financial Statements for the year ended December 31, 2024.

For the year ended December 31, 2024, the Company issued 2,512,581 shares of common stock for conversion of the debt, which includes the final conversion shares noted below.

On December 12, 2024, the Company entered into an agreement with the remaining three Note Holders who held an outstanding principal balance as of December 12, 2024, pursuant to which the three remaining Note Holders elected to immediately convert all of the outstanding principal of certain convertible notes into shares of the Company's common stock. The agreement satisfied the full outstanding debt owed to the remaining three Note Holders under the Convertible Notes. Following the conversion, 335,661 shares of common stock were issued to the Note Holders in accordance with the terms of the Convertible Notes, as amended. The Company recorded a debt inducement conversion expense of approximately $388 thousand within Other Expense, net on the Consolidated Financial Statements for the year ended December 31, 2024. No further amounts are owed by the Company under the Convertible Notes as of December 31, 2025.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

*Series A Preferred Stock*

The Series A Preferred Stock is not convertible into or exchangeable into common stock of the Company, except upon the occurrence of a delisting event or change of control. Per the Company's Certificate of Designations, Preferences and Rights of 9.0% Series A Cumulative Perpetual Preferred Stock ("Series A Certificate of Designations"), if there is an occurrence of delisting or change of control, the holders of Series A Preferred Stock will have the right to convert the number of preferred A shares into a number of common shares by the lesser of (a) the sum of the $25.00 liquidation preference per share of Series A Preferred Stock plus the amount of any accumulated and unpaid dividends divided by the closing price of the common stock on ten consecutive trading days preceding a delisting event, or (b) the share cap of 0.2817.

*Series B Preferred Stock*

On July 19, 2022, the Company entered into a Securities Purchase Agreement (the "Series B SPA") with an accredited investor (the "Series B Investor") pursuant to which the Company sold to the Series B Investor 62,500 shares of Series B Preferred Stock, for a purchase price of $5.0 million. The shares of Series B Preferred Stock are initially convertible, subject to certain conditions, into 46,211 shares of common stock, at a price per share of $135.25 per share, a 20% premium to the closing price of the common stock on July 18, 2022, subject to adjustment as set forth in the Certificate of Designations of Preferences, Rights and Limitations for the Series B Preferred Stock ("Series B Certificate of Designations"). On October 1, 2024, the Company agreed, as a condition of a waiver of the Series B Investor's right of first refusal and participation rights in connection with the SEPA, to reduce the conversion price to $5.00 upon stockholder approval, which was obtained on November 15, 2024.

In addition, in 2022, the Company issued to the Series B Investor 60,000 common stock purchase warrants (the "Series B Warrants") to purchase up to an aggregate of shares of common stock. In connection with the above referenced waiver, the exercise price of these warrants was reduced to $0.01 per share and an additional 140,000 warrants exercisable for $0.01 per share were issued. The Series B Investor exercised the 60,000 Series B Warrants on April 22, 2025 through a cashless warrant exercise resulting in the issuance of 59,131 shares of common stock.

Effective from October 1, 2024, the sale of common stock as a result of conversion of Series B Preferred Stock and exercise of the new 140,000 warrants is subject to a 12-month lockup, followed by a 12 month leak out where the holder may not sell shares during the lockup period and may sell up to 1/12<sup>th</sup> of total conversion and warrant exercise shares per month during the leak out. The effects of the modification of the Series B Preferred Stock on October 1, 2024, including repriced and newly issued penny warrants, and dividend amendments, created an extinguishment on the Series B preferred stock in which the Company recorded a deemed dividend of approximately $1.7 million which relates to the fair value consideration of the modified preferred stock less the original carrying value for the year ended December 31, 2024, excluding the consideration of the Preferred B dividend as discussed below.

Effective on February 5, 2026, per the terms of the Series B Certificate of Designations and lock up, the conversion price was adjusted to $0.96, and therefore can result in a conversion of 6,510,416 shares of common stock. It is noted that the conversion of shares is in a leak out period of 12 months from February 6, 2026 to February 6, 2027 in which the holder may sell up to 1/12th of total conversion and warrant exercises during the leak out.

***Common Stock***

The Company has one class of common stock, par value $0.001 per share. Each share of the Company's common stock is entitled to one vote on all matters submitted to stockholders. As of December 31, 2025 and December 31, 2024, there were 102,531,089 and 10,607,020 shares of common stock outstanding, respectively.

The Board of Directors had not declared any Series A Preferred Stock dividends beginning October 2022 through December 31, 2025, as such the Company has accumulated approximately $18.5 million of dividends in arrears on the Series A Preferred Stock through December 31, 2024, and an additional $11.1 million of dividends in arrears for the year ended December 31, 2025, for a total of approximately $29.6 million.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

The Company's Series B Preferred Stock included a 10% accruing dividend compounded daily for 12 months from the original issue date of July 20, 2022, and annually thereafter, that may be paid in cash or stock at the Company's option at the earlier of (i) the date the Series B Preferred Stock is converted, or (ii) the Series B Dividend Termination Date. On August 11, 2023, the Company paid a mandatory dividend on its outstanding Series B Convertible Preferred Stock in the amount of approximately $656 thousand. Pursuant to the Certificate of Designation for the Series B Stock, the Company had the option to pay the dividend in cash or shares of Common Stock. In fiscal year 2023, pursuant to a Dividend Payment Agreement, the Company and the holder of the Series B Stock agreed to satisfy the payment of the dividend through the issuance of 44,000 shares of its Common Stock and 70,300 pre-funded warrants (the "Pre-funded Warrants").

Effective October 1, 2024 the dividend payment obligation has been modified to be annual. The amendment resulted in annual dividend payments going forward. As a result of the amendment, the Company would be obligated to make annual dividend payments for the period starting from July 2023 as per the Series B Preferred Consent and Waiver, however, the board of directors has not yet declared any dividends for that period. As such, the Company has accumulated approximately $941 thousand dividends in arrears in relation to the Series B Preferred Stock through December 31, 2024, and an additional $686 thousand of dividends in arrears for the year ended December 31, 2025, for a total of approximately $1.6 million.

Company matching contributions were approximately $239 thousand and $200 thousand, for the years ended December 31, 2025 and 2024. The Company may also make additional discretionary contributions in amounts as determined by management and the Board of Directors. There were no additional discretionary contributions by the Company for the years 2025 or 2024.

The Company notes as continuing operations was in a net loss for the years ended December 31, 2025 and 2024, basic and diluted EPS is the same balance as continuing operations acts as the control amount which would cause antidilution. Not included in the computation of earnings per share, assuming dilution, for the year ended December 31, 2025, were options to purchase 2,645 shares of the Company's common stock, 508,980 nonvested restricted stock units, 26,831,293 unvested restricted stock awards, and 22,309,840 outstanding warrants not exercised which excludes penny warrants that can be potentially exercised. These potentially dilutive items were excluded because the calculation of incremental shares resulted in an anti-dilutive effect.

Not included in the computation of earnings per share, assuming dilution, for the year ended December 31, 2024, were options to purchase 3,245 shares of the Company's common stock, 210,312 nonvested restricted stock units, 3,220,632 nonvested restricted stock awards, and 2,793,798 outstanding warrants not exercised.

**12. Stock Based Compensation**

Stock-based incentive awards are provided to employees and directors under the terms of the Company's 2012 Equity Incentive Plan (the "2012 Plan"), which was amended and restated as of October 20, 2016, the 2014 Equity Incentive Plan (the "2014 Plan"), the 2021 Stock Incentive Plan (the "2021 Plan"), which was amended and restated effective as of October 29, 2021, May 27, 2022, and March 10, 2023, respectively, and the 2023 Stock Incentive Plan (the "2023 Plan"), which was amended and restated effective as of June 29, 2023, (collectively, the "Plans"). Awards under the Plans have generally included at-the-money options and restricted stock grants.

***2023 Plan***

The 2023 Plan was adopted by the Board on February 10, 2023 and approved by the stockholders on March 10, 2023.

On June 29, 2023, at the Annual Shareholder Meeting, the Amended and Restated 2023 Stock Incentive Plan was approved. The Amended and Restated 2023 Plan, among other things, increased the number of shares of our Common Stock reserved for issuance thereunder, on a quarterly basis, to 23.75% of the shares of our Common Stock outstanding on the measurement date. Subject to certain adjustments as provided herein, the maximum aggregate number of Common Shares that may be issued hereunder (excluding the number of Common Shares subject to Specified Awards (as hereinafter

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

defined)) (i) pursuant to the exercise of Options, (ii) as unrestricted Common Shares or Restricted Stock, and (iii) in settlement of RSUs shall be limited to, beginning with the third quarter of our fiscal year ending December 31, 2023 (or July 1, 2023), 23.75% of the number of Common Shares outstanding as of the first trading day of each quarter. Subject to certain adjustments as provided herein, (A) Common Shares subject to this Plan shall include Common Shares which reverted back to this Plan in a prior quarter, and (B) the number of Common Shares that may be issued under this Plan may never be less than the number of Common Shares that are then outstanding under (or available to settle existing) Awards. For purposes of determining the number of Common Shares available under this Plan, Common Shares withheld by the Company to satisfy applicable tax withholding or exercise price obligations pursuant to Section 10(e) of this Plan shall be deemed issued under this Plan. In the event that, prior to the date this Plan shall terminate, any Award granted under this Plan expires unexercised or unvested or is terminated, surrendered, or cancelled without the delivery of Common Shares, or any shares of Restricted Stock are forfeited back to the Company, then the Common Shares subject to such Award may be made available for subsequent Awards under the terms of this Plan. As used in this Plan, "Specified Awards" shall mean (i) Awards to Eligible Persons who are not employed or engaged by the Company or any of its subsidiaries as of the last day of any fiscal quarter of the Company, commencing with the fiscal quarter ending March 31, 2023 and (ii) Awards that have a grant date at least three (3) years prior to the last day of any fiscal quarter of the Company, commencing with the fiscal quarter ending March 31, 2023.

***2021 Plan***

The Company's 2021 Plan was adopted by the Board on February 12, 2021 and approved by the stockholders on March 25, 2021. The 2021 Plan was amended and restated effective as of October 29, 2021, and May 27, 2022, respectively. The 2021 Plan authorizes the Company to issue shares of common stock upon the exercise of stock options, the grant of restricted stock awards, and the conversion of restricted stock units (collectively, the "Awards"). The Compensation Committee has full authority, subject to the terms of the 2021 Plan, to interpret the 2021 Plan and establish rules and regulations for the proper administration of the 2021 Plan.

On March 10, 2023, at the Special Shareholder Meeting, the Third Amended and Restated 2021 Stock Incentive Plan was approved. The Third Amended and Restated 2021 Plan, among other things, (a) increased the number of shares of our Common Stock reserved for issuance thereunder, on a quarterly basis, to 18.75% of the shares of our Common Stock outstanding on the measurement date and (b) allows us to grant awards of shares of our 9.0% Series A Cumulative Perpetual Preferred Stock ("Series A Preferred Stock") (with and without restrictions). Subject to certain adjustments as provided in the Third Amended and Restated 2021 Plan, the maximum aggregate number of shares of our Common Stock that may be issued under the Third Amended and Restated 2021 Plan (excluding the number of shares of our Common Stock subject to Specified Awards (as defined below)) (i) pursuant to the exercise of stock options, (ii) as unrestricted or restricted Common Stock, and (iii) in settlement of RSUs shall be limited to, beginning with the first quarter of our fiscal year ending December 31, 2023 (or January 1, 2023), 18.75% of the number of shares of our Common Stock outstanding as of the first trading day of each quarter. Subject to certain adjustments as provided in the Third Amended and Restated 2021 Plan, the maximum aggregate number of shares of our Series A Preferred Stock that may be issued under the Third Amended and Restated 2021 Plan as unrestricted or restricted Series A Preferred Stock shall equal $3,600,000 valued as of the effective date of the Third Amended and Restated 2021 Plan as determined at the lower of the closing price of our Series A Preferred Stock on Nasdaq on such date or the average of the daily volume weighted average price of our Series A Preferred Stock on Nasdaq as reported by Bloomberg L.P. for a period of five (5) consecutive trading days ending on such date. Subject to certain adjustments as provided in the Third Amended and Restated 2021 Plan, (i) shares of our Common Stock and Series A Preferred Stock, as applicable, subject to the Third Amended and Restated 2021 Plan shall include shares of our Common Stock and Series A Preferred Stock, as applicable, which revert back to the Third Amended and Restated 2021 Plan in a prior quarter or fiscal year, as applicable, pursuant to the paragraph below, and (ii) the number of shares of our Common Stock and Series A Preferred Stock, as applicable, that may be issued under the Third Amended and Restated 2021 Plan may never be less than the number of shares of our Common Stock and Series A Preferred Stock, as applicable, that are then outstanding under (or available to settle existing) 2021 Plan Award grants. For purposes of the Third Amended and Restated 2021 Plan, "Specified Awards" means (i) 2021 Plan Awards issued to Eligible Persons who are not employed or engaged by us or any of our subsidiaries as of the last day of any fiscal quarter, commencing with the fiscal quarter ending March 31, 2023, and (ii) 2021 Plan Awards that have a grant date at least three (3) years prior to the last day of any fiscal quarter, commencing with the fiscal quarter ending March 31, 2023. The exclusion of Specified Awards from the determination of the maximum aggregate number of shares of our Common Stock available for issuance under the Third Amended and Restated 2021 Plan could have material effect on the number of shares of our Common Stock available for issuance thereunder and could have a material dilutive effect on our stockholders.

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

The Board approved an amendment to the 2021 Plan on October 16, 2024. The amendment was subsequently approved by the stockholders at the Special Meeting on November 15, 2024. Under the Plan, the number of shares of common stock available for awards is limited to 18.75% of the number of Common Shares outstanding as of the first trading day of each quarter. The amendment to the Plan would change this limitation to 22.75% from the first quarter of our fiscal year ending December 31, 2025 through the second quarter of our fiscal year ending December 31, 2027. However, under the amendment to the Plan, effective at the end of the second quarter of our fiscal year ending December 31, 2027 the percentage will revert to 18.75% of the number of Common Shares outstanding as of the first trading day of each quarter.

Under the 2023 Plan and 2021 Plan, the Company may grant stock options, restricted stock awards (RSAs) and restricted stock units (RSUs) to executive, management, employees, directors, and certain nonemployee personnel. The awards issued under the Plans can vest immediately, over time or based upon the achievement of market, performance, or service conditions. RSAs and RSUs can vest immediately but generally vest ratably over three years and Performance RSUs generally fully vest after three years, subject to achieving market, service or performance conditions. In addition, the Company recognizes certain Awards held by certain employees and nonemployees that vest upon separation. Each share granted subject to an Award reduces the number of shares available under the 2023 Plan and 2021 Plan by one share.

The fair value of stock options is estimated based on the Black-Scholes model, taking into account the historical volatility of our stock, consistent with the accounting guidance. The risk-free interest rate is based on the risk-free zero-coupon rate for a period consistent with the expected option term at the time of grant. The expected option term is calculated based on our historical forfeitures and cancellation rates.

During April 2024, the Company cancelled certain vested Awards and modified the terms of certain unvested Awards, to permit different settlement outcomes. The service period and vesting terms were changed at the time of modification. All such vested Awards were fully vested as of the cancellation date and all compensation costs had been recognized. All such unvested equity awards were probable of vesting as of the modification date and the change was accounted for as a Type I modification. In a Type I modification, the Company is required to calculate the incremental difference of the awards, which equals the difference of new award value inclusive of estimated forfeitures and the fair value of the original award as of the modification date. As of the modification date, there is no reversal or adjustment of previously recognized stock compensation expenses.

Within the 2021 and 2023 Plans, certain master grant agreements were executed on April 15, 2024 that have the potential for future additional grants based on additional stock activity through certain anti-dilution provisions. A mutual understanding of the terms and conditions for the specific awards cannot be obtained until a later date after all stock activity has occurred in the future period and necessary approvals are obtained. In addition, and as discussed below, Board approval is the initial step in establishing the grant date, following which two discrete conditions must be met: (i) the recipient must still be employed or acting as a director as of such date, and (ii) availability to grant such awards under the Plan is present. This methodology applies to all grants under the Master Stock Agreements, as discussed further below. When Board approval is obtained and the two grant conditions are met, the grant date will be identified and evidenced through an additional restricted stock agreement. The compensation cost will be recognized per the vesting schedule within the agreement with no catch-up for the reduced period.

The accounting impact resulting from the recognition of this equity-based compensation limits the comparability of the Company's financial statements between periods.

***2014 Plan***

The 2014 Plan was adopted by the Company's Board of Directors on March 12, 2014, and approved by its stockholders on June 11, 2014. The 2014 Plan provides an initial aggregate number of 500,000 shares of common stock that may be awarded or issued. The number of shares that may be awarded under the 2014 Plan and awards outstanding may be subject to adjustment on account of any stock dividend, spin-off, stock split, reverse stock split, split-up, recapitalization, reclassification, reorganization, combination or exchange of shares, merger, consolidation, liquidation, business combination, exchange of shares or the like. Under the 2014 Plan, the Board-appointed administrator of the 2014 Plan is authorized to issue stock options (incentive and nonqualified), stock appreciation rights, restricted stock, restricted stock units, phantom stock, performance awards and other stock-based awards to employees, officers and directors of, and other individuals providing bona fide services to or for, the Company or any affiliate of the Company. Incentive stock options may only be granted to employees of the Company and its subsidiaries.

***2012 Plan***

The 2012 Plan was adopted by the Company's Board of Directors on April 14, 2012, and approved by its stockholders on June 14, 2012. The 2012 Plan was amended and restated by the Board of Directors effective October 20, 2016. The October 2016 amendment allowed for the award agreement, or another agreement entered into between the Company and the award grantee to vary the method of exercise of options issued under the 2012 Plan and an agreement entered into between the Company and the award grantee to vary the provisions governing expiration of options or other awards under the 2012 Plan following termination of the award recipient. The 2012 Plan provides an initial aggregate number of 600,000 shares of common stock that may be awarded or issued. The number of shares that may be awarded under the 2012 Plan and awards outstanding may be subject to adjustment on account of any recapitalization, reclassification, stock split, reverse stock split and other dilutive changes in our common stock. Under the 2012 Plan, the Board of Directors is authorized to issue stock options (incentive and nonqualified), stock appreciation rights, restricted stock, restricted stock units and other stock-based awards to employees, officers, directors, consultants and advisors of the Company and its subsidiaries. Incentive stock options may only be granted to employees of the Company and its subsidiaries.

38,153 of the restricted stock awards vested immediately, 3,302,485 of the restricted stock awards vest at separation from the Company, 690,223 of the restricted stock awards vest 33% on June 1, 2024, 33% on June 1, 2025 and 34% on June 1, 2026, 334,289 of the restricted stock awards vest 33% on June 1, 2025, 33% on June 1, 2026 and 34% on June 1, 2027, 14,505 of the restricted stock awards vest on June 1, 2025, 14,894 of the restricted stock award vest on June 1, 2026, 1,710 of the restricted stock awards vest on June 1, 2027, 462,212 of the restricted stock awards vest 33% on September 1, 2025, 33% on September 1 , 2026 and 34% on September 1, 2027, 264,000 of the restricted stock awards vest 33% on December 1, 2024, 33% on December 1 , 2025 and 34% on December 1, 2026, and 467,388 of the restricted stock awards vest 33% on December 1, 2025, 33% on December 1 , 2026 and 34% on December 1, 2027.

No options were granted under the 2023 Plan, the 2021 Plan, the 2014 Plan and the 2012 Plan for the years ended December 31, 2025 and December 31, 2024.

During August 2025, upon the successful election to the Board, certain Awards with separation vesting incurred an extension of the vesting term by three years. As such, a modification occurred. All such unvested equity awards were probable of vesting as of the modification date and the change was accounted for as a Type I modification. In a Type I modification, the Company is required to calculate the incremental difference of the awards, which equals the difference of new award value inclusive of estimated forfeitures and the fair value of the original award as of the modification date. As of the modification date, there is no reversal or adjustment of previously recognized stock compensation expense. The modification related to 492,645 awards of restricted stock granted to two board members. There was no incremental compensation cost resulting from the modification since the awards are grants of restricted stock. The difference between the fair value of the original award as of the modification date and the fair value of the new award as of the modification date are identical, as fair value is determined based on the stock price as of that date.

During November 2025, the Compensation Committee revised the vesting conditions of all common stock grants to non-employee directors from time-based vesting to separation vesting. As such, a modification occurred. All such unvested equity awards were probable of vesting as of the modification date and the change was accounted for as a Type I modification. In a Type I modification, the Company is required to calculate the incremental difference of the awards, which equals the difference of new award value inclusive of estimated forfeitures and the fair value of the original award as

------

of the modification date. As of the modification date, there is no reversal or adjustment of previously recognized stock compensation expense. The modification related to 462,508 awards of restricted stock granted to two board members. There was no incremental compensation cost resulting from the modification since the awards are grants of restricted stock. The difference between the fair value of the original award as of the modification date and the fair value of the new award as of the modification date are identical, as fair value is determined based on the stock price as of that date.

There were no other modifications during the year ended December 31, 2025.

On April 15, 2024, a modification related to the cancellation of 48,547 underwater stock options was granted to eight board members. The options were replaced with new awards of restricted stock. The amount of incremental compensation cost resulting from the modification was approximately $4.0 million. There were no other modifications during the year ended December 31, 2024.

Stock-based compensation expense for the years ended December 31, 2025, and 2024 was generated from stock options, restricted stock units and restricted stock awards. Stock options are awards that allow holders to purchase shares of the Company's common stock at a fixed price. Certain options granted may be fully or partially exercisable immediately, may vest on other than a four-year schedule or vest upon attainment of specific performance criteria. Option exercise prices are generally equivalent to the closing market value price of the Company's common stock on the date of grant. Unexercised options generally terminate ten years after the date of grant. Restricted stock units and restricted stock awards generally vest one to three years after the date of grant, although certain awards may vest immediately or vest upon attainment of specific performance criteria.

Share-based compensation expense recognized in the Consolidated Statements of Operations is based on awards ultimately expected to vest, therefore, awards are reduced for estimated forfeitures. The accounting standard requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company will recognize the compensation expense on a straight-line basis over the service period for the entire awards. As of December 31, 2025 and December 31, 2024, the awards from the Plans are presented within the stockholders' equity section of the Company's balance sheet.

Total share-based compensation expense, related to the Company's share-based awards, recognized for the years ended December 31, was included within the representative group comprised as follows:

---

| | | |
|:---|:---|:---|
| | **2025** | **2024** |
| (Dollars in thousands) |  |  |
| Cost of cryptocurrency mining revenue, exclusive of depreciation | $45 | $48 |
| Cost of data hosting revenue, exclusive of depreciation | 120 | 112 |
| General and administrative expenses, exclusive of depreciation and amortization | 10401 | 5151 |
| Share-based compensation expense | $10566 | $5311 |

---

Total unrecognized compensation costs related to non-vested stock options as of December 31, 2025 and December 31, 2024 is approximately $16 thousand and $54 thousand, respectively, and is expected to be recognized over a weighted-average remaining vesting period of approximately 0.41 years and 1.42 years, respectively.

Presented below is a summary of the Company's stock option activity for the Plans for the years ended December 31:

**13. Commitments and Contingencies**

**Commitments:**

***Leases***

The Company determines whether an arrangement is a lease at inception. The Company has operating and financing leases for certain manufacturing, land, office facilities and certain equipment. The leases have remaining lease terms of two years to less than twenty-two years. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

Lease expense for these leases is recognized on a straight-line basis over the lease term. For the twelve months ended December 31, total lease costs are comprised of the following:

---

| | | |
|:---|:---|:---|
| (Dollars in thousands) |  |  |
|  | **2025** | **2024** |
| Operating lease cost | $82 | $157 |

| &nbsp;&nbsp; Total finance lease costs | 128 |  |
| &nbsp;&nbsp;Total net lease cost | $260 | $157 |

---

Short-term leases are leases having a term of twelve months or less. The Company recognizes short-term leases on a straight-line basis and does not record a related lease asset or liability for such leases. On April 3, 2025, Soluna KK Energy ServiceCo, LLC ("Soluna KK Energy"), a subsidiary of the Company, entered into a lease agreement for 50 acres of property located in Willacy County, Texas, for the purpose of constructing, installing, operating, and maintaining modular data centers and related facilities. Soluna KK Energy had the ability to terminate the lease within six months of April 3, 2025. Through July 2025, there was uncertainty over project funding and whether the Company would extend the lease agreement. As such, the Company recorded the lease agreement as short-term. In August 2025, Soluna KK Energy extended the lease agreement for the additional term of twenty-two years. Accordingly, the Company recorded a right-of-use asset and lease liability.

**Contingencies:**

***Spring Lane Capital Contingency***

The Company has a potential contingency associated with an agreement with Spring Lane of up to $250 thousand which would be reduced by a proportion of funding received from Spring Lane up to the $45.0 million aggregate contribution cap. The Company considers the probability of a payment for the contingency to be remote.

***Legal***

We are subject to legal proceedings, claims and liabilities which arise in the ordinary course of business. When applicable, we accrue for losses associated with legal claims when such losses are probable and can be reasonably estimated. These accruals are adjusted as additional information becomes available or circumstances change. Legal fees are charged to expense as they are incurred.

On December 29, 2022, NYDIG filed a complaint against the NYDIG Defendants regarding the NYDIG Loans made by NYDIG to Borrower pursuant to a Master Equipment Finance Agreement, dated December 30, 2021, that were secured by certain assets of Borrower and guaranteed by Guarantor pursuant to a written guaranty agreement. The NYDIG Defendants s and NYDIG entered into a Stipulation and Agreed Judgment which was approved by the Court on February 23, 2024, whereby judgment was granted to NYDIG on the counts in the complaint and the NYDIG Defendants became jointly and severally liable for an aggregate amount of approximately $9.2 million plus interest (the "Agreed Judgment Amount").

On September 29, 2025, the NYDIG Defendants and NYDIG entered into a Settlement Agreement (the "Settlement Agreement"), pursuant to which the NYDIG Defendants and NYDIG agreed to fully settle and resolve the Agreed Judgment Amount and all other matters relating to the NYDIG Loans in exchange for the NYDIG Defendants ' agreement to make certain settlement payments to NYDIG in accordance with the Settlement Agreement. As of the date of filing these consolidated financial statements, the Settlement Agreement has been fully satisfied and paid.

**14. Related Party Transactions**

***HEL Transactions***

As discussed in the Company's 2023 Annual Report, on October 29, 2021, the Company completed the Soluna Callisto acquisition pursuant to the merger agreement (the "Merger Agreement"). The purpose of the transaction was for SCI to acquire substantially all of the assets (other than those assets physically located in Morocco) formerly held by Harmattan Energy, Ltd. ("HEL"), which assets consisted of SCI's existing pipeline of certain cryptocurrency mining projects that HEL previously transferred to SCI, which was formed expressly for this purpose, and to provide SCI with the opportunity to directly employ or retain the services of four individuals whose services it had retained through HEL prior to the merger. As a result of the merger, each share of common stock of Soluna Callisto issued and outstanding immediately prior to the effective time of the merger, other than shares owned by the Company or any of our subsidiaries, was cancelled and converted into the right to receive a proportionate share of the Merger Consideration.

In connection with the Soluna Callisto acquisition, effective as of October 29, 2021, upon and subject to the terms and conditions of the Termination Agreement, on November 5, 2021: (1) the existing Operating and Management Agreements between HEL and SCI were terminated in all respects; and (2)(A) SCI paid HEL $725 thousand, (B) SHI issued to HEL the Termination Shares, and (C) HEL and SHI entered into an Amended and Restated Contingent Rights Agreement that, among other things, amended the existing Contingent Rights Agreement by and between HEL and SHI, dated January 13, 2020, to provide SHI the right to invest directly in certain cryptocurrency mining opportunities being pursued by HEL. SHI filed a registration statement with the SEC to register the resale of the Termination Shares on February 14, 2022.

Due to conditions being met within the Merger Agreement in relation to energization and retention of employees, the Company has advised SCI US Holdings LLC, a Delaware limited liability company, who is the sole Effective Time Holder (as defined in the Merger Agreement) of the right to receive the Merger Shares and that 19,800 Merger Shares were issued on May 26, 2023, 39,600 Merger Shares were issued on October 10, 2023, and 17,820 Merger Shares were issued on October 8, 2025. SCI US Holdings LLC has consented to the issuance of such Merger Shares as required under the Merger Agreement and has directed the Company to issue such Merger Shares to its affiliate, HEL. Following the issuance of the 77,220 Merger Shares, a total of 41,580 Merger Shares remains available for possible issuance through October 29, 2026 pursuant to the terms of the Merger Agreement as of December 31, 2025. On February 6, 2026, the Company issued an

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

additional 10,692 Merger Shares, due to the 18 MW of energization being met, as such as of the date of these consolidated financial statements, a total of 30,888 Merger Shares remains available for possible issuance through October 29, 2026.

Four of the Company's directors have various affiliations with HEL. The Company notes that the only transaction with HEL for the year ended December 31, 2025 was in relation to the issuance of Mergers Shares noted above.

The Company owned approximately 1.79% of HEL, calculated on a converted fully diluted basis, as of December 31, 2025 and December 31, 2024. The Company may enter into additional transactions with HEL in the future.

***MeOH Power, Inc.***

On December 18, 2013, MeOH Power, Inc. and the Company executed a Senior Demand Promissory Note (the Note) in the amount of $380 thousand to secure the intercompany amounts due to the Company from MeOH Power, Inc. upon the deconsolidation of MeOH Power, Inc. Interest accrues on the Note at the Prime Rate in effect on the first business day of the month, as published in the Wall Street Journal. At the Company's option, all or part of the principal and interest due on this Note may be converted to shares of common stock of MeOH Power, Inc. at a rate of $0.07 per share. Interest began accruing on January 1, 2014. The Company recorded a full allowance against the Note. As of December 31, 2025 and December 31, 2024, $403 thousand and $385 thousand, respectively, of principal and interest are available to convert into shares of common stock of MeOH Power, Inc. Any adjustments to the allowance are recorded as miscellaneous expenses during the period incurred.

**15. Variable Interest Entities and Voting Interest Entities**

On January 26, 2022, DVSL was created in order to construct, own, operate and maintain variable data centers in order to support the mining of cryptocurrency assets, batch processing and other non-crypto related activities (collectively, the "Project"). On May 3, 2022, SCI entered into a Bilateral Master Contribution Agreement (the "Bilateral Contribution Agreement") with Spring Lane Capital, pursuant to which Spring Lane agreed, pursuant to the terms and conditions of such agreement, to make one or more capital contributions to, and in exchange for equity in, SCI or one of its subsidiaries up to an aggregate amount of $35 million, amended to $45 million in the third quarter of fiscal year 2024 to fund certain projects to develop green data centers co-located with renewable energy assets (the "Spring Lane Commitment").

On August 5, 2022, the Company entered into a Contribution Agreement (the "Dorothy Contribution Agreement") with Spring Lane, Soluna DV Devco, LLC ("Devco"), an indirect wholly owned subsidiary of SCI, and DVSL an entity formed in order to further the Company's development for Project Dorothy, (each, a "Party" and, together, the "Parties"). Pursuant to the Dorothy Contribution Agreement, the Company committed to a capital contribution of up to approximately $26.3 million to DVSL (the "Company Commitment"), and on August 5, 2022, the Company was deemed to have contributed approximately $8.1 million, through payment of capital expenditures and development costs made on behalf of DVSL by the Company prior to August 5, 2022. Further under the Agreement, Spring Lane committed to a capital contribution of up to $12.5 million to DVSL (the "Spring Lane Dorothy Commitment"), and as of December 31, 2023, Spring Lane had actually contributed approximately $4.8 million. Under the Dorothy Contribution Agreement, the Company and Spring Lane have committed to make subsequent contributions, up to their respective Company Commitment and Spring Lane Dorothy Commitment amounts, on a pro rata basis, upon receipt of a contribution request from DVSL, as set forth in the Dorothy Contribution Agreement and subject to the satisfaction of certain conditions described therein. The proceeds of any subsequent commitments will be applied to pay project costs in accordance with the project budget.

In exchange for their contributions, the Company and Spring Lane were issued 67.8% and 32.2% of the Class B Membership Interests in DVSL, respectively, and were admitted as Class B members of DVSL. Further pursuant to the Dorothy Contribution Agreement, DVSL issued 100% of its Class A Membership Interests to Devco.

The Company evaluated this legal entity under *ASC 810, Consolidations* and determined that DVSL is a variable interest entity ("VIE") that should be consolidated into the Company, with a non-controlling interest recorded to account for Spring Lane's equity ownership of the Company. The Company has a variable interest in DVSL. The entity was designed by the Company to create an entity for outside investors to invest in specific projects. The creation of this entity resulted in the Company, through its equity interest in DVSL, absorbing operational risk that the entity was created to create and distribute, resulting in the Company having a variable interest in DVSL.

On March 10, 2023, the Company along with Devco, and DVSL, a Delaware limited liability company (the "Project Company") entered into a Purchase and Sale Agreement (the "Purchase and Sale Agreement") with Soluna SLC Fund I

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

Projects Holdco, LLC, a Delaware limited liability company ("Spring Lane") that is wholly owned indirectly by Spring Lane Management LLC. The Project Company was constructing a modular data center with a peak demand of 25 MW (the "Dorothy Phase 1A Facility").

Under a series of transactions in February 2023 and March 2023, culminating in the March 10, 2023 Purchase and Sale Agreement, the Company sold to Spring Lane certain Class B Membership Interests for a purchase price of $7.5 million (the "Sale"). After giving effect to the Sale, the Company owned 6,790,537 Class B Membership Interests (constituting 14.6% of the Class B Membership Interests) and Spring Lane owns 39,791,988 Class B Membership Interests (constituting 85.4% of the Class B Membership Interests). The cash portion of the purchase price paid by Spring Lane to the Company was approximately $5.8 million, which represented the purchase price of $7.5 million less the Company's pro rata share of certain contributions funded entirely by Spring Lane in the earlier portion of this series of transactions occurring during February 2023 and March 2023. As a further part of these transactions, the parties agreed that from January 1, 2023 onwards, the Company would bear only 14.6% of the costs relating to the construction and operation of the Dorothy Phase 1A Facility, compared to its 67.8% share until that time, including during the calendar year 2023. After Spring Lane Capital realizes an 16% Internal Rate of Return hurdle on its investments, the Company retains the right to 50% of the profits on DVSL.

Concurrently with the Sale, the Company, Spring Lane, Devco and the Project Company entered into (a) the Fourth Amended and Restated Limited Liability Company Agreement of the Project Company, dated as of March 10, 2023 (the "Fourth A&R LLCA"), an amendment and restatement of the Third Amended and Restated Limited Liability Company Agreement of the Project Company dated as of March 3, 2023, and (b) the Amended and Restated Contribution Agreement, dated as of March 10, 2023 (the "A&R Contribution Agreement"), an amendment and restatement of the Contribution Agreement dated as of August 5, 2022. The Fourth A&R LLCA provides for certain updates in respect of Spring Lane's majority ownership. The A&R Contribution Agreement reflects updated pro rata member funding percentages as a result of the Sale as well as updated contribution caps for each of the Company and Spring Lane.

As of January 1, 2023, there were no changes in the Limited Liability Agreement of DVSL other than those related to incorporating the new investment and the purpose and design of DVSL has not changed. The Company evaluated this legal entity under ASC 810, Consolidations and determined that this entity is a VIE, as the equity holders as a group do not have the characteristics of a controlling financial interest. Even though SLC has a significant portion of the Class B membership, the Company holds all the Class A membership, which gives them the ability to control the significant decisions made in the ordinary course of business. The Company has the right to receive benefits that could potentially be significant to the VIE through its Class A membership interest, as it is eligible to receive 50% of distributions upon SLC obtaining a specified internal rate of return. The non-controlling shareholders do not hold substantive participating rights, voting rights or liquidation rights. Effective January 1, 2023, the Company's ownership in DVSL was reduced from 67.8% to 14.6%; see above for details.

In September 2025, the Company agreed to terms of a debt facility with Generate under a Credit and Guarantee Agreement, as discussed in Note 8. Several events occurred in connection with the debt facility, [1] the Company completed a restructuring of the subsidiaries that comprise "Project Dorothy 1A" and "Project Dorothy 2" (herein referred to as the "Dorothy Restructuring"), [2] Soluna DVSL ComputeCo LLC, Soluna DVSL II ComputeCo LLC, and Soluna KK I ComputeCo LLC entered into a First Priority Leasehold Deed of Trust (the "Deed of Trust") with Generate which provides Generate with the power of sale and right of entry and possession of the Trust Property.

Following the Dorothy Restructuring, Project Dorothy 1A consists of Soluna DVSL JVCo, LLC ("DVSL JVCo"), which has Class A units owned by SDI and Class B units owned by SLC (Soluna SLC Fund I). DVSL JVCo is then the sole parent of Soluna DVSL HoldCo, LLC ("DVSL HoldCo"), which holds 100% of the Class A units in DVSL. The Class B units of DVSL ComputeCo are held by the Company. The total ownership of Project Dorothy 1A remains such that the SDI holds all Class A units and that SLC holds 85.4% of Class B units with the Company holding the remaining 14.6% of Class B units.

The Company noted that 1) there is no substantive change to the ascending view of the organizational chart since the Company (through SDI and newly created DVSL JVCo and DVSL ComputeCo) beneficially own the Class A units (i.e., managing units) of DVSL and 2) there are no substantive kick-out rights that exist within Project Dorothy 1A that would cause SDI to not have the ability to direct the activities that most significantly impact the economic performance of DVSL. In addition, the entity's obligation to absorb losses and right to receive benefits has not changed. As such, Soluna would continue to consolidate the entity since a change in control has not occurred following the execution of Generate Credit Agreement and Deed of Trust.

On May 9, 2023, the Company's indirect subsidiary DVCC completed a strategic partnership and financing with a special purpose vehicle, Navitas West Texas Investments SPV, LLC**,** ("Navitas") organized by Navitas Global, to complete the second phase of the Dorothy Project ("Dorothy 1B"). Under a Contribution Agreement among the parties, the Company owned a substantially complete 25MW data center under construction, in which the Company had contributed capital expenditures for the data center. Soluna and Navitas amended and restated the Initial LLCA (the "Existing LLCA") to reflect Navitas' contribution of $4.5 million and its receipt of 4,500 Membership Interests, constituting 26.5% of the outstanding Membership Interests of DVCC. On June 2, 2023, Soluna and Navitas amended and restated the Existing LLCA to (a) reflect (i) Navitas's additional capital contribution of approximately $7.6 million and receipt of an additional 7,597 Membership Interests, for a total of 12,097 Membership Interests and 49% ownership of DVCC, and (ii) Soluna's additional capital contribution of $1.34 million and receipt of an additional 1,340 Membership Interests, for a total of 12,590 Membership Interests and 51% ownership of DVCC, and (b) describe the respective rights and obligations of the Members and the management of DVCC. As of December 31, 2025, Navitas owns 49% and Soluna owns 51% of DVCC.

The Company evaluated this legal entity under *ASC 810, Consolidations* and determined that DVCC is a VIE that should be consolidated into the Company, with a non-controlling interest recorded to account for Navitas' equity ownership of DVCC. The Company has a variable interest in DVCC. The entity was designed by the Company to create an entity for outside investors to invest in specific projects. The creation of this entity resulted in the Company, through its equity

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

interest in DVCC, absorbing operational risk that the entity was created to create and distribute, resulting in the Company having a variable interest in DVCC.

DVCC is a VIE of the Company due to DVCC being structured with non-substantive voting rights. This is due to the following two factors being met as outlined in *ASC 810-10-15-14* that require the VIE model to be followed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.The voting rights of the Company are not proportional to their obligation to absorb the expected losses of the legal entity. The Company gave Navitas veto rights over significant decisions, which resulted in Soluna having fewer voting rights relative to their obligation to absorb the expected losses of the legal entity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.Substantially all of DVCC's activities are conducted on behalf of the Company, which has disproportionally fewer voting rights.

Also, the Company is the primary beneficiary due to having the power to direct the activities of DVCC that most significantly impact the performance of DVCC due to its role as the manager handling the day-to-day activities of DVCC as well as majority ownership and the obligation to absorb losses or gains of DVCC that could be significant to the Company.

Accordingly, the accounts of DVCC are consolidated in the accompanying financial statements.

The carrying amount of the VIE's assets and liabilities was as follows for DVCC:

On July 22, 2024 (the "Effective Date"), Soluna Holdings, Inc. (the "Company") closed financing for the Dorothy 2 project. This project involves Soluna Digital, Inc. (the "Developer") and Soluna DVSL II ComputeCo, LLC ("DVSL II"), a special purpose vehicle initially owned solely by the Developer. They are collaborating on the development, design, procurement, and construction of a 48 MW modular data center (the "Project Dorothy 2") in Silverton, Texas. This facility

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

is owned by DVSL II and operated by Soluna US Services, LLC, and may engage in cryptocurrency, batch processing, and other non-crypto related activities. It is adjacent to two other company modular data center projects at the same site.

Project Dorothy 2 is financed by Soluna2 SLC Fund II Project Holdco LLC, an investment vehicle of SLC with a capital contribution of up to $29.98 million, and the Developer, as the parent company of DVSL II, with an initial capital contribution of up to $4.6 million. As of the Effective Date, the Company and the Developer became co-owners of DVSL II. In exchange for contributions to DVSL II, the Company and SLC were initially issued 42% and 58% of the Class B Membership Interests in DVSL II respectively, and were admitted as Class B members of DVSL II. Further, DVSL II issued 100% of its Class A Membership Interests to SDI. In relation to distributions, once ERCOT Achievement Date has been met (date on which SLC and the Company have mutually agreed upon the parameters for power trading or demand response program in the ERCOT market) until the Target Return Date (last day of quarter in which the Class B members achieve an 18% internal rate of return), the Class A members will obtain 7.5% of the distributable cash with the remaining 92.5% being distributed to the Class B members on a pro-rata basis. After the Target Return Date is met, 50% of distributable cash will be allocated to the Class A members and 50% allocated to the Class B members in accordance with their membership interests.

Project Dorothy 2 allows the Developer to invest in DVSL II, with the total ownership of the Developer and its affiliates capped at 49% of the Class B Membership Interests. This investment can occur within 30 days after the Effective Date (treated equally to the initial Investor), from day 31 to 180 days after the Effective Date (subject to a purchase price formula with a 20% discount rate), or after 180 days with the initial Investor's approval.

On May 16, 2024, the Company secured $1.0 million in financing from SLC for equipment and machinery for Project Dorothy 2 through an Equipment Loan Agreement (the "ELA") between SDI SL Borrowing - 1, LLC (the "Borrower") and SLC. On that date, SLC lent the Borrower $720 thousand to purchase medium voltage cables and low voltage switchboards. This debt was later assigned to DVSL II on the Effective Date. Subsequently, the Borrowing amount in full by issuing the Investor Class B Membership Interests in the Dorothy 2 project valued at three times the borrowing amount (i.e., $2.16 million).

On April 4, 2025, the Company transferred its Class B Membership to SLC, resulting in 0% Class B Membership Interests held by the Company. SDI still retains 100% Class A Membership Interests in DVSL II as of December 31, 2025. Based on evaluation, the Company would be able to consolidate this entity.

The Company evaluated this legal entity under ASC 810, Consolidations and determined that this entity is a VIE, as the equity holders as a group do not have the characteristics of a controlling financial interest. Even though SLC has all of the Class B membership, the Company holds all the Class A membership, which gives them the ability to control the significant decisions made in the ordinary course of business. The Company has the right to receive benefits that could potentially be significant to the VIE through its Class A membership interest, as it is eligible to receive 50% of distributions upon SLC obtaining a specified internal rate of return. The non-controlling shareholders do not hold substantive participating rights, voting rights or liquidation rights.

In September 2025, the Company agreed to terms of a debt facility with Generate under a Credit and Guarantee Agreement, as discussed in Note 8. Several events occurred in connection with the debt facility, [1] the Company completed a restructuring of the subsidiaries that comprise "Project Dorothy 1A" and "Project Dorothy 2" (herein referred to as the "Dorothy Restructuring"), [2] Soluna DVSL ComputeCo LLC, Soluna DVSL II ComputeCo LLC, and Soluna KK I ComputeCo LLC entered into a First Priority Leasehold Deed of Trust (the "Deed of Trust") with Generate which provides Generate with the power of sale and right of entry and possession of the Trust Property.

Following the Dorothy Restructuring, Project Dorothy 2 consists of Soluna DVSL II JVCo, LLC ("DVSL II JVCo"), which has Class A units owned by the Developer and Class B units owned by SLC. DVSL II JVCo is then the sole parent of Soluna DVSL II HoldCo, LLC ("DVSL II HoldCo"), which is the sole owner of DVSL II ComputeCo. The total ownership of Project Dorothy 2 remains such that the Developer holds all Class A units and that SLC holds all Class B units.

The Company noted that [1] there is no substantive change to the ascending view of the organizational chart since the Company (through the Developer and newly created DVSL II JVCo and DVSL II ComputeCo) beneficially own the Class A units (i.e., managing units) of DVSL II and [2] there are no substantive kick-out rights that exist within Project Dorothy 2 that would cause the Developer to not have the ability to direct the activities that most significantly impact the economic performance of DVSL II. In addition, the entity's obligation to absorb losses and right to receive benefits has not changed.

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

As such, Soluna would continue to consolidate the entity since a change in control has not occurred following the execution of Credit Agreement and Deed of Trust.

The carrying amount of the assets and liabilities was as follows for DVSL II JVCo:

On July 22, 2025 (the "Effective Date"), Soluna Digital, Inc. ("SDI"), a subsidiary of the Company, finalized a contribution agreement and operating agreement for Project Kati, a 166 MW facility located in Willacy County, Texas, which is expected to be delivered in two phases at 83 MW each. This project involves SDI as the Developer, Soluna KKSL JVCo LLC (the "KKSL JVCo"), a special purpose vehicle initially owned solely by SDI, and Soluna2 Kati Project Holdco LLC ("Spring Lane"). This facility is owned by KKSL JVCo, and operated by Soluna US Services, LLC, and may engage in cryptocurrency, batch processing, and other non-crypto related activities.

Currently Project Kati 1 is financed by Soluna2 Kati Project Holdco LLC, an investment vehicle of Spring Lane Capital ("SLC") with a capital contribution of up to $48.98 million. In exchange for contributions to KKSL JVCo, SDI was issued 100% of Class A Membership Units and SLC was initially issued 100% of the Class B Membership Interests in KKSL JVCo, respectively, and were admitted as Class B members of KKSL JVCo. Further, SDI and Spring Lane entered into a Developer Investment Side Letter in which allows SDI to invest into KKSL JVCo up to 49% of ownership in the Class B

**16. Segment Information**

The Company applies ASC 280, *Segment Reporting*, in determining its reportable segments. The Company has adopted ASU) 2023-07, *Segment Reporting (Topic 280): Improvement to Reportable Segment Disclosures* (ASU 2023-07), which

------

<u>[**Table of Contents**](#ib7fc3eff18db4e65b009fbd4412e117d_7)</u>

requires disclosure of incremental segment information on an annual and interim basis, primarily through enhanced disclosures of significant segment expenses for the year ended December 31, 2025. Operating segments are aggregated into a reportable segment if the operating segments have similar quantitative economic characteristics and if the operating segments are similar in the following qualitative characteristics: (i) nature of products and services; (ii) nature of production processes; (iii) type or class of customer for their products and services; (iv) methods used to distribute the products or provide services; and (v) if applicable, the nature of the regulatory environment. The Company's reportable segments are identified based on the types of service performed. The Company has three reportable segments: Cryptocurrency Mining, Data Center Hosting, and High-Performance Computing. In the third quarter of 2024, the Company initiated Soluna Cloud Services, a new business line to provide high performance computing services to support generative AI workstreams, but decided to exit active provision of these services during the first quarter of 2025 and will focus in the future on provision of colocation services at our datacenters to host customers in the AI generative space.

The guidance requires that segment disclosures present the measure(s) used by the Chief Operating Decision Maker ("CODM") to decide how to allocate resources and for purposes of assessing such segments' performance. The Company's CODM is composed of several members of its senior leadership team directed by the CEO and CFO who use revenue and cost of revenues which formulate gross profit (loss), as well as total general and administrative expenses of the reporting segments to assess the performance of the business of our reportable operating segments and allocate resources. Operating profit (loss) is used to evaluate actual results against expectations, which are based on comparable prior results, current budget, and current forecast. Non-cash items of depreciation and amortization are included within both costs of sales and general and administrative expenses, however only depreciation through the Company's site levels are evaluated for segment performance.

In the adoption of ASU 2023-07 *Segment Reporting (Topic 280): Improvement to Reportable Segment Disclosure*s, the most significant provision was for the Company to disclose significant segment expenses (ie: costs of revenue) that are regularly provided to the CODM. Utility costs, wages and benefit related costs, facility and equipment costs, and depreciation costs at the site level were determined to be significant segment expenses. The CODM only reviews general and administrative expenses by site level as a whole, and not by significant expenses. No operating segments have been aggregated to form the reportable segments. The Company does not allocate all assets to the reporting segments as these are managed on an entity-wide basis. Therefore, the Company does not separately disclose the total assets of its reportable operating segments.

The Cryptocurrency Mining segment generates revenue from the cryptocurrency the Company earns through its Bitcoin mining activities, which is currently generated from Project Dorothy, and previously from Project Sophie and Marie. The Data Center Hosting segment generated revenue from hosting services performed to third-party Bitcoin mining customers at the Company's data centers, which were previously at Project Marie and currently from Project Sophie and Project Dorothy. The High-Performance Computing Services segment may generate revenue from either the sale or lease of HPC assets (such as Project Ada which leased GPUs), or from HPC/AI data centers to be leased to third-party HPC/AI customers. This segment began generating revenue in December 2024, as Project Ada worked to build its customer base. With the termination of the HPE Agreement, revenue was minimal for the year ended December 31, 2025, and for the year ended December 31, 2024, the Company incurred approximately $28.6 million on the loss on contract associated with the termination of the HPE Agreement .

The Company includes Demand Response revenue as a reconciling item of revenue and is not included within the three reportable segments. The Company utilizes our data centers to deliver demand response services to grid operators or utilities. Under these arrangements with a grid operator, the Company agrees to be available to ramp down a registered data center's power consumption to a specific target level. In exchange, the grid pays the company a fee for this dispatch right, provided the Company can perform within certain parameters. The Company can be providing any type of service at the data centers whether it be Cryptocurrency Mining, Data Center Hosting, or AI to generate demand service revenue.

**Exhibit 4.8**

**DESCRIPTION OF THE REGISTRANT'S SECURITIES**

**REGISTERED PURSUANT TO SECTION 12**

**OF THE SECURITIES EXCHANGE ACT OF 1934**

Soluna Holdings, Inc., or the Company, we, us or our, has three classes of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended, or the Exchange Act, common stock, $0.001 par value per share, or common stock, 9.0% Series A Cumulative Perpetual Preferred Stock, par value $0.001 per share, or Series A Preferred Stock, and Series B Convertible Preferred Stock, par value $0.001 per share, or Series B Preferred Stock (together with the Series A Preferred Stock, the "preferred stock").

The following description of the terms of our shares of common and preferred stock is a summary only. This summary is not complete and is qualified in its entirety by reference to the Company's articles of incorporation, as amended (the "Articles of Incorporation"), and the Company's bylaws (the "Bylaws"), the Certificate of Designation, Preferences and Rights of the Series A Preferred Stock, or the Series A COD, Certificate of Designations of Preferences, Rights and Limitations for the Series B Preferred Stock, or the Series B COD, and applicable Nevada law. The Company's Articles of Incorporation and Bylaws, the Series A Certificate and the Series B Certificate are filed as exhibits to this Annual Report on Form 10-K.

**General**

Our Articles of Incorporation authorizes us to issue up to 375,000,000 shares of stock, consisting of 365,000,000 shares of common stock and 10,000,000 shares of preferred stock, of which 6,040,000 shares were classified as shares of Series A Preferred Stock and 187,500 were classified as Series B Preferred Stock, as of March 27, 2026.

Under our Articles of Incorporation, our Board of Directors, or the Board, without stockholder approval, is authorized to provide for the issuance of shares of common stock or preferred stock in one or more classes or series, to establish the number of shares in each class or series, and to fix the terms thereof.

**Common Stock**

*Voting rights*

The holders of our common stock are entitled to one vote per share held on all matters on which a vote of our common stockholders is taken. Stockholders do not have cumulative voting rights in the election of directors. The election of directors of the Company is decided by plurality vote and all other questions are decided by a majority of the votes cast by our stockholders present in person or by proxy, except as otherwise required by the Nevada Revised Statutes ("NRS") or our Articles of Incorporation. Our Articles of Incorporation provide that notwithstanding any other provision of our Articles of Incorporation or our Bylaws (and notwithstanding the fact that some lesser percentage may be specified by law, the Articles of Incorporation, or the Bylaws), any director or the entire Board may be removed at any time, but only for cause upon the affirmative vote of 75% or more of the outstanding shares of capital stock entitled to vote for the election of directors at a meeting called for that purpose.

The Board is divided into three classes, with each class consisting, as nearly as may be possible, of one-third of the total number of directors, with the terms of the classes scheduled to expire in successive years. At each annual meeting of the Company's stockholders, the stockholders elect the members of a single class of directors for three-year terms.

*Dividends*

The holders of our common stock are entitled to receive dividends when, as, and if declared by the Board, out of funds legally available therefor.

------

*Liquidation*

Except as otherwise provided under our Articles of Incorporation (including the terms of any preferred stock), upon liquidation, dissolution, or the winding up of the Company, holders of our common stock are entitled to receive any remaining assets of the Company in proportion to the respective number of shares held after payment of and reservation for Company liabilities.

*Preemptive Rights*

The holders of shares of our common stock do not have any preemptive right to subscribe for or purchase any shares of any class or series of our capital stock.

*Redemption Rights*

The outstanding shares of common stock are not subject to redemption by the Company. To the extent that the Company issues additional shares of common stock, the relative interest in the Company of existing stockholders will likely be diluted.

**Preferred Stock**

Our Articles of Incorporation authorize the Board, without obtaining stockholder approval, to issue up to 10,000,000 shares of preferred stock, from time to time, in one or more series, and to fix the number of shares and determine for each such series such voting powers, designations, preferences, and relative participating, optional, or other rights and such qualifications, limitations, or restrictions thereof. The Board is also expressly authorized to increase or decrease (but not below the number of such series then outstanding) the number of shares of any series subsequent to the issuance of shares of that series. If the number of shares of any series is decreased, the shares no longer designated as shares of such series will resume the status of "blank check" preferred stock and may be designated, again, as a new series of preferred stock by the Board.

As of March 27, 2026, 6,040,000 shares of our preferred stock were designated as shares of Series A Preferred Stock and 187,500 shares were designated as Series B Preferred Stock. Unless the applicable prospectus supplement indicates otherwise, we will have the right to "reopen" a previous issue of a series of preferred stock by issuing additional preferred stock of such series.

**Series A Preferred Stock**

The following is a summary of some general terms and provisions of our Series A Preferred Stock. Because it is a summary, it does not contain all of the information that may be important to you. If you want more information, you should read our Articles of Incorporation (including the Series A COD and Series B COD) and Bylaws, copies of which are filed as exhibits to this prospectus.

*Voting Rights*

Holders of the Series A Preferred Stock do not have any voting rights, except as described below or as otherwise required by law. In any matter in which the Series A Preferred Stock may vote (as expressly provided in the Series A COD or as may be required by law), each share of Series A Preferred Stock will be entitled to one vote per $25.00 of liquidation preference; provided that if the Series A Preferred Stock and any other stock ranking on parity to the Series A Preferred Stock as to dividend rights and rights as to the distribution of assets upon the Company's liquidation, dissolution or winding up are entitled to vote together as a single class on any matter, the holders of each will vote in proportion to their respective liquidation preferences.

*Dividends*

------

Subject to the preferential rights, if any, of the holders of any class or series of capital stock of the Company ranking senior to the Series A Preferred Stock as to dividends, the holders of the Series A Preferred Stock are entitled to receive, when, as and if declared by the Board (or a duly authorized committee of the Board), only out of funds legally available for the payment of dividends, cumulative cash dividends at the annual rate of 9.0% of the $25.00 liquidation preference per year (equivalent to $2.25 per year).

*Liquidation*

In the event of the voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, holders of shares of Series A Preferred Stock will be entitled to be paid out of the assets of the Company legally available for distribution to its stockholders (*i.e.*, after satisfaction of all the Company's liabilities to creditors, if any) and, subject to the rights of holders of any shares of each other class or series of capital stock ranking, as to rights to the distribution of assets upon the Company's voluntary or involuntary liquidation, dissolution or winding up, senior to the Series A Preferred Stock, a liquidation preference of $25.00 per share, plus an amount equal to any accumulated and unpaid dividends to the date of payment (whether or not declared), before any distribution or payment may be made to holders of shares of our common stock or any other class or series of the Company's capital stock ranking, as to rights to the distribution of assets upon any voluntary or involuntary liquidation, dissolution or winding up, junior to the Series A Preferred Stock (the "liquidation preference").

If, upon such voluntary or involuntary liquidation, dissolution or winding up of the Company's affairs, the assets of the Company legally available for distribution to the Company's stockholders are insufficient to pay the full amount of the liquidation preference on all outstanding shares of Series A Preferred Stock and the corresponding amounts payable on all shares of each other class or series of capital stock of the Company ranking, as to rights to the distribution of assets upon any voluntary or involuntary liquidation, dissolution or winding up, on parity with the Series A Preferred Stock, then the holders of the Series A Preferred Stock and each such other class or series of capital stock of the Company ranking, as to rights to the distribution of assets upon the Company's voluntary or involuntary liquidation, dissolution or winding up, on parity with the Series A Preferred Stock will share ratably in any distribution of assets in proportion to the full liquidation preference to which they would otherwise be respectively entitled.

*Preemptive Rights*

Holders of Series A Preferred Stock do not, as holders of Series A Preferred Stock, have any preemptive rights to purchase or subscribe for our common stock or any other security of the Company.

*Redemption Rights*

The Company is not required to redeem the Series A Preferred Stock at any time. The Series A Preferred Stock is perpetual and has no maturity date. On or after August 26, 2025, the Series A Preferred Stock may be redeemed at the Company's option, in whole or in part, from time to time, at a redemption price of $25.00 per share, plus all dividends accumulated and unpaid (whether or not declared) on the Series A Preferred Stock up to, but not including, the date of such redemption. The Company also has a special optional right to redeem the Series A Preferred Stock, by paying a redemption price of $25.00 per share, plus all dividends accumulated and unpaid(whether or not declared) on the Series A Preferred Stock up to, but not including, the date of such redemption, if a Delisting Event or Change of Control (each as defined in the Series A COD) occurs. The Series A Preferred Stock is not subject to any sinking fund.

*Conversion Rights*

The shares of Series A Preferred Stock are not convertible into or exchangeable for any other property or securities of the Company or any other entity, except upon the occurrence of a Delisting Event or Change of Control (each as defined in the Series A COD), in which case (unless the Company has already elected to redeem such shares), shares of Series A Preferred Stock are convertible into shares of our common stock (or equivalent value of alternative consideration), as calculated pursuant to the terms of the Series A COD.

------

*Ranking*

The Series A Preferred Stock will, as to dividend rights and rights as to the distribution of assets upon the Company's liquidation, dissolution or winding up, rank: (1) senior to all classes or series of our common stock and to all other capital stock issued by the Company expressly designated as ranking junior to the Series A Preferred Stock, (2) on parity with any future class or series of the Company's capital stock expressly designated as ranking on parity with the Series A Preferred Stock; (3) junior to any future class or series of the Company capital stock expressly designated as ranking senior to the Series A Preferred Stock; and (4) junior to all the Company's existing and future indebtedness (including subordinated indebtedness and any indebtedness convertible into common stock or preferred stock) and other liabilities with respect to assets available to satisfy claims against the Company and structurally subordinated to the indebtedness and other liabilities of (as well as any preferred equity interests held by others in) existing or future subsidiaries of the Company. The Company may issue junior capital stock and parity capital stock, as described above, at any time and from time to time in one or more series without the consent of the holders of the Series A Preferred Stock. The Company may not issue any senior capital stock, as described above, without the consent or affirmative vote of the holders of at least two-thirds of the outstanding shares of Series A Preferred Stock and each other class or series of our preferred stock entitled to vote thereon, voting as a single class.

**Series B Preferred Stock**

The following is a summary of some general terms and provisions of our Series B Preferred Stock. Because it is a summary, it does not contain all of the information that may be important to you. If you want more information, you should read our Articles of Incorporation (including the Series A COD and Series B COD) and Bylaws, copies of which are filed as exhibits to this prospectus.

*Redemption Rights*

The Series B Preferred Stock is perpetual and has no maturity date. Provided that no shares of Series A Preferred Stock are outstanding, either the Company or the holder may, at its option, at any time on or after the later of (i) the third anniversary of the Original Issue Date and (ii) Note Release Date (each as defined in the Series B COD and together, the "Redemption Date"), if all of the shares of Series B Preferred Stock have not been converted to shares of common stock prior to the Redemption Date, redeem the outstanding shares of Series B Preferred Stock, in whole or in part, at any time after the Redemption Date, at a cash redemption price per share of Series B Preferred Stock equal to the Stated Value, or $100.00. In the event that our common stock ceases to trade on a national exchange for twenty consecutive Trading Days, if at least a majority of the holders so elect, they may present the Company with a Notice of Redemption. The Series B Preferred Stock is not subject to any mandatory redemption, sinking fund or other similar provisions.

*Conversion Rights*

Each share of Series B Preferred Stock shall be convertible, at any time and from time to time on or after the later of a date that is (i) 180 days after the Original Issue Date (as defined in the Series B COD) or (ii) the date on which those certain senior secured convertible notes in the original aggregate principal amount of $16,304,348 that were issued on or about October 25, 2021 have been fully redeemed, defeased, or converted, at the option of the holder thereof, into that number of shares of our common stock determined by dividing the Stated Value of such share of Series B Preferred Stock by the Conversion Price (as defined below). Holders shall also be paid any accrued and unpaid cash dividends and/or issued shares of our common stock, if dividends are payable in shares of our common stock, based on the applicable rate of conversion, at the same time such shares are issued to the holders. If a Fundamental Transaction (as defined in the Series B COD) occurs, then immediately prior to the closing of such Fundamental Transaction, each share of Series B Preferred Stock shall, without further action from the holder thereof, automatically convert into common stock at the then effective conversion rate, without regard to any beneficial ownership limitation under the Series B COD.

*Conversion Price*

------

The conversion price for the Series B Preferred Stock shall equal $0.96 (the "Conversion Price"), subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of our common stock that occur after the First Amendment Effective Date (as defined in the Series B COD).

*Dividends*

Holders of Series B Preferred Stock shall be entitled to receive, and the Company shall pay, by issuing shares of our common stock (or cash at the Company's option) to such holders, dividends on shares of Series B Preferred Stock, based on the Stated Value, at a rate of ten percent (10%) per annum, commencing on the Original Issue Date (as defined in the Series B COD) until the date that such share of Series B Preferred Stock is converted to common stock or otherwise redeemed (the "Dividend Termination Date"). Such dividends shall accrue and be compounded daily on the basis of a 360-day day year and twelve 30-day months and shall be paid annually on each anniversary of the Original Issue Date (or within five (business days thereof) and, in the event that shares of Series B Preferred Stock are converted to common stock or otherwise redeemed, on the Dividend Termination Date (or within five (5) business days thereof). No other dividends shall be paid on shares of Series B Preferred Stock.

*Voting Rights*

Series B Preferred Stock will vote with the shares of common stock, on an as-converted to common stock basis, with respect to all matters on which the holders of common stock are entitled to vote, provided, that no holder (together with such holder's Affiliates and Attribution Parties (each as defined in the Series B COD) shall be entitled to vote an amount of shares of common stock (including Series B Preferred Stock on as an-converted to common stock basis) in excess of the Beneficial Ownership Limitation (as defined in the Series B COD), with any remaining amount of shares held by such holder, its Affiliates and Attribution Parties deemed non-voting. In addition, as long as any shares of Series B Preferred Stock are outstanding, the Company shall not, without the affirmative vote of the holders of a majority of the then outstanding shares of the Series B Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Series B Preferred Stock or alter or amend the Series B COD, (b) amend its Articles of Incorporation or other charter documents in any manner that adversely affects any rights of the holders, (c) increase the number of authorized shares of preferred stock, or (d) enter into any agreement with respect to any of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the amount the holder would be entitled to receive if the Series B Preferred Stock were fully converted (disregarding for such purposes any conversion limitations hereunder) to common stock, which amounts shall be paid pari passu with all holders of common stock.

In addition, in the case of either (a) or (b) above, the holders will be entitled to the payment of all accrued and unpaid dividends on the Series B Preferred Stock and, in the event any of such dividends are payable in shares of common stock, the cash value of such shares of common stock upon Liquidation. The Company shall mail written notice of any such Liquidation, not less than forty-five (45) days prior to the payment date stated therein, to each holder.

*Ranking*

Except to the extent that the holders of at least a majority of the outstanding Series B Preferred Stock (the "Required Holders") expressly consent to the creation of Parity Stock (as defined below) or Senior Preferred Stock

------

(as defined below), all shares of common stock and all shares of capital stock of the Company authorized or designated after the date of the designation of the Series B Preferred Stock shall be junior in rank to the Series B Preferred Stock with respect to the preferences as to dividends, distributions and payments upon the liquidation, dissolution and winding up of the Company (such junior stock collectively, "Junior Stock"). Without limiting any other provision of the Series B COD, without the prior express consent of the Required Holders, voting separate as a single class, the Company shall not hereafter authorize or issue any additional or other shares of capital stock that is (i) of senior rank to the Series B Preferred Stock in respect of the preferences as to dividends, distributions and payments upon the liquidation, dissolution and winding up of the Company (collectively, "Senior Preferred Stock"); provided, however, that the Series B Preferred Stock shall be pari passu to the Series A Preferred Stock, including any Series A Preferred Stock that shall be issued subsequent to the designation of the Series B Preferred Stock, or (ii) of pari passu rank to the Series B Preferred Stock in respect of the preferences as to dividends, distributions and payments upon the liquidation, dissolution and winding up of the Company (collectively, the "Parity Stock").

**Terms of the Preferred Stock That We May Offer and Sell to You**

We summarize below some of the provisions that will apply to the preferred stock that we may offer to you unless the applicable prospectus supplement provides otherwise. This summary may not contain all information that is important to you. You should read the prospectus supplement, which will contain additional information and which may update or change some of the information below. Prior to the issuance of a new series of preferred stock, we will further amend our articles of incorporation, as amended, by filing a certificate of designation designating the stock of that series and the terms of that series. We will file a copy of the certificate of designation that contains the terms of each new series of preferred stock with the Nevada Secretary of State and the SEC each time we issue a new series of preferred stock. Each certificate of designation will establish the number of shares included in a designated series and fix the designation, powers, privileges, preferences and rights of the shares of each series as well as any applicable qualifications, limitations or restrictions. You should refer to the applicable certificate of designation as well as our articles of incorporation, as amended, before deciding to buy shares of our preferred stock as described in the applicable prospectus supplement.

Our board of directors has the authority, without further action by the stockholders, to issue preferred stock in one or more series and to fix the number of shares, dividend rights, conversion rights, voting rights, redemption rights, liquidation preferences, sinking funds, and any other rights, preferences, privileges and restrictions applicable to each such series of preferred stock. The issuance of any preferred stock could adversely affect the rights of the holders of common stock and, therefore, reduce the value of the common stock. The ability of our board of directors to issue preferred stock could discourage, delay or prevent a takeover or other corporate action. The terms of any particular series of preferred stock will be described in the prospectus supplement relating to that particular series of preferred stock, including, where applicable:

 ● the designation, stated value and liquidation preference of such preferred stock;

 ● the number of shares within the series;

 ● the offering price;

 ● the dividend rate or rates (or method of calculation), the date or dates from which dividends shall accrue, and whether such dividends shall be cumulative or noncumulative and, if cumulative, the dates from which dividends shall commence to cumulate;

 ● any redemption or sinking fund provisions;

------

●  the amount that shares of such series shall be entitled to receive in the event of our liquidation, dissolution or winding-up;

 ● the terms and conditions, if any, on which shares of such series shall be convertible or exchangeable for shares of our stock of any other class or classes, or other series of the same class;

 ● the voting rights, if any, of shares of such series; the status as to reissuance or sale of shares of such series redeemed, purchased or otherwise reacquired, or surrendered to us on conversion or exchange;

●  the conditions and restrictions, if any, on the payment of dividends or on the making of other distributions on, or the purchase, redemption or other acquisition by us or any subsidiary, of the common stock or of any other class of our shares ranking junior to the shares of such series as to dividends or upon liquidation;

 ● the conditions and restrictions, if any, on the creation of indebtedness by us or by any subsidiary, or on the issuance of any additional stock ranking on a parity with or prior to the shares of such series as to dividends or upon liquidation; and

 ● any additional dividend, liquidation, redemption, sinking or retirement fund and other rights, preferences, privileges, limitations and restrictions of such preferred stock.

**Anti-Takeover Effects of Certain Provisions of Our Articles of Incorporation and Bylaws, and Nevada Law**

Our Articles of Incorporation and Bylaws contain provisions and terms that may delay, defer, or prevent a tender offer or change in control of the Company that a stockholder might consider to be in his, her, or its best interests, including attempts that might result in a premium being paid over the market price for shares of our Common Stock. The Company expects that such provisions and terms may have the effect of discouraging extraordinary corporate transactions with respect to the Company, such as hostile takeover bids, and will instead encourage any potential acquiror of the Company to first correspond with our Board. These provisions and terms include:

●  Special meetings of stockholders may only be called by the by the chairman of the board or the chief executive officer, or, if there be no chairman of the board and no chief executive officer, by the president, and shall be called by the secretary upon the written request of at least a majority of the Board or the holders of not less than a majority of the voting power of the Company's stock entitled to vote.

 ● The Company maintains a classified Board that is divided into three classes serving for respective three-year terms. As a result, it would take at least two successive annual meetings of shareholders to replace a majority of the members of our Board.

●  Vacancies on the Board may be filled by majority vote of remaining directors then in office, even ifless than a quorum, with the individual elected to serve for the remainder of the unexpired term.

●  Any director of the Company may be removed from service as a director only after the affirmative voteof 75% or more of outstanding shares of stock entitled to vote for the election of directors, at a meetingcalled for that purpose.

Nevada's "combinations with interested stockholders" statutes, NRS 78.411 through 78.444, inclusive, prohibit specified types of business "combinations" between certain Nevada corporations and any person deemed to

------

be an "interested stockholder" for two years after such person first becomes an "interested stockholder" unless the corporation's board of directors approves the combination (or the transaction by which such person becomes an "interested stockholder") in advance, or unless the combination is approved by the board of directors and sixty percent of the corporation's voting power not beneficially owned by the interested stockholder, its affiliates and associates. Further, in the absence of prior approval certain restrictions may apply even after such two year period. However, these statutes do not apply to any combination of a corporation and an interested stockholder after the expiration of four years after the person first became an interested stockholder. For purposes of these statutes, an "interested stockholder" is any person who is (1) the beneficial owner, directly or indirectly, of ten percent or more of the voting power of the outstanding voting shares of the corporation, or (2) an affiliate or associate of the corporation and at any time within the two previous years was the beneficial owner, directly or indirectly, of ten percent or more of the voting power of the then outstanding shares of the corporation. The definition of the term "combination" is sufficiently broad to cover most significant transactions between a corporation and an "interested stockholder." These statutes generally apply to Nevada corporations with 200 or more stockholders of record. However, a Nevada corporation may elect in its articles of incorporation not to be governed by these particular laws, but if such election is not made in the corporation's original articles of incorporation, the amendment (1) must be approved by the affirmative vote of the holders of stock representing a majority of the outstanding voting power of the corporation not beneficially owned by interested stockholders or their affiliates and associates, and (2) is not effective until 18 months after the vote approving the amendment and does not apply to any combination with a person who first became an interested stockholder on or before the effective date of the amendment. We made an election to opt out of these statutes in our original articles of incorporation and have not amended such provision.

Nevada's "acquisition of controlling interest" statutes (NRS 78.378 through 78.3793, inclusive) contain provisions governing the acquisition of a controlling interest in certain Nevada corporations. These "control share" laws provide generally that any person that acquires a "controlling interest" in certain Nevada corporations may be denied voting rights, unless a majority of the disinterested stockholders of the corporation elect to restore such voting rights. These laws will apply to us as of a particular date if we were to have 200 or more stockholders of record (at least 100 of whom have addresses in Nevada appearing on our stock ledger at all times during the 90 days immediately preceding that date) and do business in the State of Nevada directly or through an affiliated corporation, unless our Articles of Incorporation or Bylaws in effect on the tenth day after the acquisition of a controlling interest provide otherwise. These laws provide that a person acquires a "controlling interest" whenever a person acquires shares of a subject corporation that, but for the application of these provisions of the NRS, would enable that person to exercise (1) one-fifth or more, but less than one-third, (2) one-third or more, but less than a majority, or (3) a majority or more of all of the voting power of the corporation in the election of directors. Once an acquirer crosses one of these thresholds, shares which it acquired in the transaction taking it over the threshold and within the 90 days immediately preceding the date when the acquiring person acquired or offered to acquire a controlling interest become "control shares" to which the voting restrictions described above apply. These laws may have a chilling effect on certain transactions if our Articles of Incorporation or Bylaws are not timely amended to provide that these provisions do not apply to us or to an acquisition of a controlling interest, or if our disinterested stockholders do not confer voting rights in the control shares.

Further, NRS 78.139 provides that directors may resist a change or potential change in control of a corporation if the board of directors determines that the change or potential change in control is opposed to or not in the best interest of the corporation upon consideration of any relevant facts, circumstances, contingencies or constituencies pursuant to NRS 78.138(4).

We expect the existence of these provisions may have an anti-takeover effect with respect to transactions that our Board does not approve in advance and could result in making it more difficult to accomplish transactions that our stockholders may see as beneficial such as (i) discouraging business combinations that might result in a premium over the market price for the shares of our Common Stock; (ii) discouraging hostile takeovers which could inhibit temporary fluctuations in the market price of our Common Stock that often result from actual or rumored hostile takeover attempts; and (iii) preventing changes in our management.

Upon the request of the Investor, the Company shall promptly (but no later than the next Business Day on which the transfer agent for the Common Shares is open for business) confirm orally or in writing to the Investor the number of Common Shares then outstanding.

In connection with an Advance Notice where the Company selects an Option 1 Pricing Period, if the total number of Common Shares traded on the Principal Market during the applicable Pricing Period is less than the Volume Threshold, then the number of Advance Shares issued and sold pursuant to such Advance Notice shall be reduced to the greater of (a) 35% of the trading volume of the Common Shares on the Principal Market during such Pricing Period as reported by Bloomberg L.P., or (b) the number of Common Shares sold by the Investor during such Pricing Period, but in each case not to exceed the amount requested in the Advance Notice.

If no Minimum Acceptable Price is specified in an Advance Notice, then no Minimum Acceptable Price shall be in effect in connection with such Advance.

------

greater of (a) the number of Common Shares sold by the Investor on such Excluded Day(s), if any, or (b) such number of Common Shares elected to be subscribed for by the Investor, and the subscription price per share for each Additional Share shall be equal to the Minimum Acceptable Price in effect with respect to such Advance Notice multiplied by 97%, provided that this increase shall not cause the total Advance Shares to exceed the amount set forth in the applicable Advance Notice or any limitations set forth in Section 2.01(c).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Unconditional Contract</u>. Notwithstanding any other provision in this Agreement, the Company and the Investor acknowledge and agree that upon the Investor's receipt of a valid Advance Notice from the Company the Parties shall be deemed to have entered into an unconditional contract binding on both Parties for the purchase and sale of the applicable number of Advance Shares pursuant to such Advance Notice in accordance with the terms of this Agreement and (i) subject to Applicable Laws and (ii) subject to Section 6.18, the Investor may sell Common Shares during the Pricing Period for such Advance Notice (including with respect to any Advance Shares subject to such Pricing Period).

In connection with each Closing, the Company and the Investor shall fulfill each of its obligations as set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)On each Advance Date, the Investor shall deliver to the Company a written document, in the form attached hereto as Exhibit B (each a "<u>Settlement Document</u>"), setting forth the final number of Advance Shares to be purchased by the Investor (taking into account any adjustments pursuant to <u>Section 2.01</u>), the Market Price, the Purchase Price, the aggregate proceeds to be paid by the Investor to the Company, and a report by Bloomberg, L.P. indicating the VWAP for each of the Trading Days during the Pricing Period (or, if not reported on Bloomberg, L.P., another reporting service reasonably agreed to by the parties), in each case in accordance with the terms and conditions of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Promptly after receipt of the Settlement Document with respect to each Advance (and, in any event, not later than one Trading Day after such receipt), the Company will, or will cause its transfer agent to, electronically transfer such number of Advance Shares to be purchased by the Investor (as set forth in the Settlement Document) by crediting the Investor's account or its designee's account at the Depository Trust Company through its Deposit Withdrawal at Custodian System or by such other means of delivery as may be mutually agreed upon by the parties hereto, and transmit notification to the Investor that such share transfer has been requested. Promptly upon receipt of such notification, the Investor shall pay to the Company the aggregate purchase price of the Advance Shares (as set forth in the Settlement Document) in cash in immediately available funds to an

------

account designated by the Company in writing and transmit notification to the Company that such funds transfer has been requested. No fractional shares shall be issued, and any fractional shares that would otherwise be issued in connection with an Advance shall be rounded to the next higher whole number of shares. To facilitate the transfer of the Advance Shares by the Investor, the Common Shares will not bear any restrictive legends so long as there is an effective Registration Statement covering the resale of such Advance Shares (it being understood and agreed by the Investor that notwithstanding the lack of restrictive legends, the Investor may only sell such Common Shares pursuant to the Plan of Distribution set forth in the Prospectus included in the applicable Registration Statement and otherwise in compliance with the requirements of the Securities Act (including any applicable prospectus delivery requirements) or pursuant to an available exemption).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)On or prior to the Advance Date, each of the Company and the Investor shall deliver to the other all documents, instruments and writings expressly required to be delivered by either of them pursuant to this Agreement in order to implement and effect the transactions contemplated herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Notwithstanding anything to the contrary in this Agreement, if on any day during the Pricing Period (i) the Company notifies the Investor that a Material Outside Event has occurred, or (ii) the Company notifies the Investor of a Black Out Period, the parties agree that the pending Advance shall end and the final number of Advance Shares to be purchased by the Investor at the Closing for such Advance shall be equal to the number of Common Shares sold by the Investor during the applicable Pricing Period prior to the notification from the Company of a Material Outside Event or Black Out Period.

Section 2.03<u>Hardship</u>. In the event the Investor sells Common Shares after receipt of an Advance Notice and the Company fails to perform its obligations as mandated in this Agreement, the Company agrees that in addition to and in no way limiting the rights and obligations set forth in Article V hereto and in addition to any other remedy to which the Investor is entitled at law or in equity, including, without limitation, specific performance, it will hold the Investor harmless against any loss, claim, damage, or expense (including reasonable legal fees and expenses), as incurred, arising out of or in connection with such default by the Company and acknowledges that irreparable damage may occur in the event of any such default. It is accordingly agreed that the Investor shall be entitled to an injunction or injunctions to prevent such breaches of this Agreement and to specifically enforce (subject to Applicable Laws and the rules of the Principal Market), without the posting of a bond or other security, the terms and provisions of this Agreement.

Section 2.04<u>Completion of Resale Pursuant to the Registration Statement</u>. After the Investor has purchased the full Commitment Amount and has completed the subsequent resale of the full Commitment Amount pursuant to the Registration Statement, the Investor will promptly notify the Company in writing (which may be by e-mail) that all subsequent resales are completed and the Company will be under no further obligation to maintain the effectiveness of the Registration Statement.

The indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually reasonably satisfactory to the indemnifying party and the Investor Indemnitee or Company Indemnitee, as the case may be; provided, however, that an Investor Indemnitee or Company Indemnitee shall have the right to retain its own counsel with the actual and reasonable third party fees and expenses of not more than one counsel for such Investor Indemnitee or Company Indemnitee to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Investor

------

Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Investor Indemnitee or Company Indemnitee with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The indemnification required by this Article V shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received and payment therefor is due.

Section 5.04<u>Remedies</u>. The remedies provided for in this Article V are not exclusive and shall not limit any right or remedy which may be available to any indemnified person at law or equity. The obligations of the parties to indemnify or make contribution under this Article V shall survive expiration or termination of this Agreement.

**Insider Trading Policy**

<br>For Employees, Associates, Officers and Directors

**NOVEMBER 6, 2025**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**I.Introduction, Scope and Purpose of Policy**

In an effort to protect against prohibited "insider trading" by Soluna Holdings, Inc. (the "Company") personnel, the Company's Board of Directors adopted this insider trading policy (the "Policy") applicable to directors, officers, and associates of the Company and its subsidiaries as well as certain additional persons identified herein. The purpose of this Policy is to establish and communicate the Company's requirement that all directors, officers, and associates of the Company and its subsidiaries (and other persons subject to this Policy) comply with the laws prohibiting insider trading and tipping. Questions regarding this Policy should be directed to the Chief Financial Officer. Violation of the laws prohibiting insider trading and tipping could result in substantial criminal and civil penalties, including (1) imprisonment for up to 20 years, (2) criminal fines of up to $5 million, and (3) civil penalties of up to three times the profit gained or loss avoided, so please take time to read and understand the provisions below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**II.Definitions**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.Insider**. For purposes of this Policy, the term "Insider" refers to any person who, in the course of their employment or as a result of their relationship with the Company, is expected to regularly come into possession, or does come into possession, of material nonpublic information about the Company or its securities and/or of other entities. Therefore, in the case of the Company, directors and officers will be considered Insiders, as will other associates as well as independent contractors, auditors, consultants, attorneys, and other individuals who come into possession of such material nonpublic information. A person may retain his or her Insider status even after leaving the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.Material information**. Information is generally deemed material if a reasonable investor would consider such information important in making the decision to buy, sell, or hold a security to which the information relates; information reasonably likely to affect the price of a security will generally be material. Material information can be positive or negative and can relate to any aspect of the Company's business or any type of Company security, whether debt, equity, or hybrid. It is not possible to define all categories of material information. While materiality is always a facts and circumstances determination, there are various categories of information that are particularly sensitive and, as a general rule, should always be considered material. Exam- ples of such information are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Financial results or projections;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Major events regarding the Company's securities, including the declaration of stock splits or stock dividends, calls, redemptions, repurchases, dividends, changes in dividend policy, or the possibility of a public or private offering of securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The possibility of mergers, acquisitions, joint ventures, tender offers, or takeovers, the possible initiation of a proxy fight, and similar business developments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Significant changes in corporate objectives, operations, business plans, or strategy, or a restructuring;

1<br>

------

![picture2.jpg](picture2.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A significant cybersecurity incident, such as a data breach, or any other significant disruption in the Company's operations or loss, potential loss, breach, or unauthorized access of its property or assets, whether at its facilities or through its information technology infrastructure;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Development of a significant new product or service;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Execution or termination of significant agreements with suppliers, customers, and other business partners;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Significant related party transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Defaults under agreements or actions by creditors, customers, or suppliers relating to a company's credit standing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Major changes in previously disclosed financial information;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes in debt ratings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A change in auditors or notification that the auditor's reports may no longer be relied upon;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The disposition of a subsidiary or of material assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Significant developments in legal proceedings or regulatory actions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Significant changes in management or relations among major shareholders (including a change in control), customers, or suppliers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Impending bankruptcy or financial liquidity problems.

The above list is only illustrative; many other types of information may be considered "material," depending on the circumstances, and questions concerning the materiality of any information should be resolved in favor of materiality, meaning securities transactions should be avoid- ed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.Nonpublic information**. Information is "nonpublic" if it has not been previously disclosed to the general public. In order for information to be considered public, it must be wide- ly disseminated in a manner making it generally available to investors, including in a report or other document filed with the U.S. Securities and Exchange Commission through its EDGAR website or through an established media outlet such as Dow Jones, Returns Economic Ser- vices, The Wall Street Journal, or The Associated Press; disclosure even to large groups of investors or analysts or solely on the Company's website would not constitute public disclosure. The circulation of rumors, even if accurate and reported in the media, does not constitute effective public disclosure. In addition, even after a public announcement of material information, information will not be considered public until a sufficient time period has elapsed for the dis- closed information to be absorbed by the market. **Generally, information should not be considered public until at least *one full trading day* following the publication or release of such information.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.Related Person**. For purposes of this Policy, a Related Person includes: (1) your spouse, children, and anyone else living in your household and persons who do not live in your household but whose transactions in Company securities are directed by you or are subject to your influence or control, such as parents or adult children who consult with you before they trade in Company securities; (2) partnerships in which you are a general partner or corporations in

------

![picture2.jpg](picture2.jpg)

which you are a controlling shareholder; (3) trusts of which you are a trustee; (4) estates in which you are an executor; and (5) any other entities that you control. This Policy applies to your Related Persons to the same extent that it applies to you, and therefore you should make them aware of their need to comply with this Policy and to confer with you before they

trade in Company securities, and you should treat all such transactions for the purposes of this Policy and applicable securities laws as if the transactions were for your own account. This Pol- icy does not, however, apply to personal securities transactions of persons or entities who would otherwise fall within the definition of Related Person where the purchase or sale decision is made by a third party not controlled by, influenced by, or related to you or your Related Persons.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**E.Securities Transactions**. "Securities transactions" subject to this Policy include, among other things, open-market purchases and sales, gifts (other than gifts to Related Per- sons as such persons are subject to the restrictions of this Policy), placing a purchase or sell order, transactions in a 401(k) account or changes in 401(k) account allocation elections or contributions, and the sale of securities acquired upon the exercise of options or similar instruments. "Securities" refers not only to common stock but to all securities of the Company or other applicable entity, including but not limited to bonds, debentures, options, warrants, and partnership or limited liability company interests.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**III.Guidelines**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.Non-disclosure of Material Nonpublic Information**. Insiders must maintain the confidentiality of any material nonpublic information about the Company or about other entities (including information about transactions being considered by the Company that involve other entities) obtained while carrying out their duties to the Company. You may not disclose such information to anyone, except the persons within the Company or third-party agents of the Company (such as investment banking advisors, outside legal counsel, or outside accountants) whose positions require them to know it, until such information has been publicly disclosed. If any material nonpublic information is inadvertently disclosed, the facts of such disclosure should be immediately reported to the Chief Financial Officer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.Prohibited Trading in Company Securities**. Insiders may not engage in trans- actions in Company securities (nor recommend that another person or entity do so), either directly or through a Related Person or any other person or entity, while in possession of material nonpublic information about the Company or its securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.Quarterly Trading Restrictions ("Blackout" Periods)**. Insiders may not engage in securities transactions in Company securities (either directly or indirectly) or recommend that others do so during the period beginning 5 (five) business days before the end of a fiscal quarter and ending 1 (one) full business day after the public release of the Company's quarterly (or in the case of the fourth fiscal quarter, quarterly and annual) earnings results.

------

![picture2.jpg](picture2.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.Additional Blackout Periods**. In addition to the quarterly blackout period set forth in paragraph C above, the Company may also impose from time-to-time temporary blackout periods prohibiting all transactions in Company securities by all or certain Insiders, including in instances when items of significant importance have been communicated to associates prior to its public disclosure. These temporary blackout periods can extend into, and remain in place beyond, the Company's normal recurring quarterly blackout period. The Company will notify you if you are subject to a blackout period. You must not communicate the imposition of a temporary blackout to any other person.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**E.Pre-Clearance**. From time to time, the Company may issue a notification to certain Insiders that engaging in transactions in the Company's securities or the securities of other companies must receive prior approval. Immediately upon promulgation of such notification, all such Insiders, or persons under their supervision who have access to material nonpublic information, may not trade in the securities of the Company or any such other companies, as applicable, without the prior permission of the Chief Financial Officer. Insiders may seek such per- mission by submitting a "Request for Prior Approval of Stock Trading" (see Exhibit A attached to this Policy). If the Chief Financial Officer refuses permission, he or she is not obligated to specify the reason for denying the requested permission. You must not communicate the imposition of pre-clearance requirements to any other person.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**F.Tipping**. Insiders may be liable for, and are prohibited from, communicating or "tip- ping" material nonpublic information to any third party (a "tippee"). A person may qualify as a tippee even if he or she is not a Related Person. Insider trading violations are not limited to the disclosure of material nonpublic information or the use of such information by Insiders. Persons other than Insiders, including tippees, may be liable for insider trading if they trade or take other action based on material nonpublic information that has been misappropriated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**G.Certain Transactions**. To avoid the appearance of impropriety or inadvertent violations of insider trading restrictions, Insiders (and, where indicated, associates generally) may not engage in the types of transactions set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Short Sales*. Short sales of Company securities (i.e., the sale of shares of Company common stock that the seller does not own) may evidence an expectation on the part of the seller that the securities will decline in value, and therefore have the potential to signal to the market that the seller lacks confidence in the Company's prospects. In addition, short sales may reduce a seller's incentive to seek to improve the Company's performance. For these reasons, short sales of Company securities by directors, officers, and associates are prohibited.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Publicly Traded Options*. Given the relatively short term of publicly traded options, transactions in options may create the appearance that a director, officer, or associate is trading based on material nonpublic information and focus a director's, officers, or other

------

![picture2.jpg](picture2.jpg)

associate's attention on short-term performance at the expense of the Company's long-term objectives. Accordingly, transactions in put options, call options, or other derivative securities, on an exchange or in any other organized market, by directors, officers, and associates are prohibited.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Hedging Transactions*. Hedging or monetization transactions can be accomplished through a number of possible mechanisms, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars, and exchange funds. Such transactions may permit a director, officer, or as- sociate to continue to own Company securities obtained through employee bene- fit plans or otherwise, but without the full risks and rewards of ownership. When that occurs, the director, officer, or associate may no longer have the same objectives as the Company's other shareholders. Therefore, directors, officers, and associates are prohibited from engaging in any such transactions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Margin Accounts and Pledges*. Securities held in margin accounts or pledged as collateral may be sold by the broker or lender without the account holder or debtor's consent if he or she fails to meet a margin call or defaults on the loan. Because a margin or foreclosure sale could occur at a time when the holder/ debtor is aware of material nonpublic information or otherwise is not permitted to trade in Company securities, Insiders are prohibited from holding Company securities in a margin account or otherwise pledging Company securities as collateral for a loan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Standing and Limit Orders*. Standing and limit orders create heightened risks for insider trading violations due to the lack of control over the timing of purchases or sales that result from standing instructions to a broker because the broker could execute a transaction when the Insider is in possession of material nonpublic information about the Company. Therefore, Insiders are prohibited from placing standing or limit orders on Company securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**H.Trading in Other Securities**. Insiders may not engage in transactions in the securities of another entity (nor recommend that another person or entity do so), either directly or through a Related Person or any other person or entity, while in possession of material nonpublic information about the other entity or its securities obtained through his or her position at or the carrying out of his or her duties to the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**I.Exceptions**. The restrictions set forth in Paragraphs B, C, D, E, and H of this Section III do not apply to the exercise of stock options <u>for cash</u> under any Company equity compensation plan as the other party to the transaction is the Company itself and the price is fixed by the terms of the option agreement or the plan (but note that such requirements **<u>do</u>** apply to any sale of stock acquired by exercising any such option, including any such sale as part of a broker-assisted cashless exercise of an option or any other market sale for the

------

![picture2.jpg](picture2.jpg)

purpose of generating the cash needed to pay the exercise price of an option). Similarly, such limitations do not apply to the sale of shares of Company common stock to the Company pursuant to any stock repurchase program approved by the Company's Board of Directors. Such restrictions also do not apply to transactions pursuant to an approved Rule 10b5-1 trading plan.[1](#ic14d99abbdb94ea09bad2db908c1b4eb_4)

Please keep in mind that if a securities transaction ever becomes the subject of scrutiny, it is likely to be viewed with the benefit of hindsight. As a result, before engaging in any transaction, an Insider should carefully consider how his or her actions may be construed in the future. Any questions or uncertainties should be directed to the Chief Financial Officer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**IV.Individual Responsibility**

Insiders have ethical and legal obligations to maintain the confidentiality of information about the Company and to not engage in transactions in Company securities while in possession of material nonpublic information. Persons subject to this Policy must not engage in illegal trading and must avoid the appearance of improper trading. Each individual is responsible for making sure that he or she complies with this Policy and that any Related Person also complies with this Policy. In all cases, the responsibility for determining whether an individual is in pos- session of material nonpublic information rests with that individual, and any action on the part of the Company or any associate or director of the Company pursuant to this Policy (or otherwise) does not in any way constitute legal advice or insulate an individual from liability under applicable securities laws.

In addition, directors and executive officers should keep in mind other requirements applicable to the sale of Company securities by them, in particular, compliance with Rule 144 promulgated under, or Section 4(a)(7) of, the Securities Act of 1933, and be prepared to comply with such requirements in connection with any transactions in Company securities.

If you have any questions regarding this Policy or whether you possess material nonpublic information, it is always advisable to consult with the Chief Financial Officer prior to engaging in any securities transaction.

&nbsp;&nbsp;&nbsp;&nbsp;[1](#ic14d99abbdb94ea09bad2db908c1b4eb_4) Rule 10b5-1(c) under the Securities Exchange Act of 1934 provides an affirmative defense to a charge of insider trading where it is evident that inside information known to the trader did not play a role in trading decisions for trades made in compliance with the provisions of the rule, including pursuant to a written plan that complies with the requirements set forth therein. Such a Rule 10b5-1 plan may only be implemented by a person subject to this Policy while he or she is not aware of material nonpublic information regarding the Company and would otherwise be permitted to engage in transactions in Company securities under this Policy. Prior to entering into a trading plan under Rule 10b5-1, the individual adopting the trading plan must provide a copy of the proposed trading plan to the Chief Financial Officer and receive notification from the Chief Financial Officer that the Company has approved the trading plan before the implementation of the trading plan. The Company is not obligated to approve any Rule 10b5-1 trading plan or ensure that a trading plan submitted to the Company complies with Rule 10b5-1.
