Risk factors and legal proceedings

The risks Soluna Holdings, Inc names in Item 1A of its 10-K filed Mar 30, 2026: 66 risks under these headings, as written.4

  • 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 a limited operating history and we may not recognize operating income in the future.
  • 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.
  • If we cannot achieve or maintain profitability, stockholders could lose all or 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.
  • 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.
  • 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.
  • 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.
  • We may not be able to timely complete our future strategic growth initiatives or within our anticipated costs estimates, if at all.
  • We may have difficulty in obtaining banking services for our cryptocurrency activities.
  • 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.
The other 55 risks
  • We are subject to risks associated with our need for significant electrical power.
  • Global economic and geopolitical events, policies and conflicts may adversely affect our business, financial condition, and results of operations.
  • If we fail to effectively manage our growth, our business, financial condition, and results of operations could be harmed.
  • 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.
  • 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.
  • Risks Related to our Bitcoin Mining and Hosting Business
  • Our success depends on external factors affecting the Bitcoin industry.
  • Our profitability depends on Bitcoin prices and the stability of Digital Asset markets, which are highly volatile and largely unregulated.
  • 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.
  • 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.
  • Security breaches and irreversible transactions could result in the loss of our cryptocurrencies.
  • Uncertainty around the adoption, use, and global demand for cryptocurrencies could adversely affect our business.
  • 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.
  • Our data center business could be harmed by prolonged power outages, power and fuel shortages, capacity constraints and increases in power costs.
  • Our properties may experience damages, including damages that are not covered by insurance.
  • 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.
  • Declining block rewards, reliance on transaction fees, and network forks could adversely affect our mining operations.
  • Climate change and evolving regulations could adversely impact our business.
  • We may be affected by price fluctuations in the wholesale and retail power markets.
  • The development and acceptance of competing blockchain platforms or technologies may cause consumers to use alternative distributed ledgers or other alternatives.
  • We have an evolving business model which is subject to various uncertainties.
  • 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.
  • 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.
  • 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.
  • 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.
  • Risks Related to our Company Generally
  • Our business has and is expected to continue to have significant customer concentration.
  • Failure to attract, grow and retain a diverse and balanced customer base, including key magnet customers, could harm our business and operating results.
  • 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.
  • 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 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.
  • We may not be able to compete with other companies, some of which have greater resources and experience.
  • Our business model depends upon the demand for data centers.
  • 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.
  • Insiders continue to have substantial control over 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 could incur significant costs related to environmental matters, including from government regulation, private litigation, and existing conditions at some of our properties.
  • 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.
  • 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.
  • 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.
  • Our risk management process may not identify all risks that we are subject to and will not eliminate all risk.
  • Our officers and directors are indemnified against certain conduct that may prove costly to defend.
  • We incur significant costs as a result of operating as a public company.
  • 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.
  • We may become involved in litigation arising in the ordinary course of our business that may materially adversely affect us.
  • 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.
  • 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.
  • 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.
  • Changes in accounting rules and regulations, or interpretations thereof, could result in unfavorable accounting charges or require us to change our compensation policies.
  • Risks Related to Our Securities
  • The market price of our securities are likely to be volatile, which may cause investment losses for our shareholders.
  • 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.
  • 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.
  • 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.
  • We do not anticipate paying dividends on our common stock, and investors may 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.
  • 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.
  • 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.

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.
