Properties, in its own words

Our corporate headquarters is located in Henderson, Nevada and is owned by us. In addition, we own and lease air-cooled bitcoin mining facilities in Georgia, Mississippi and Tennessee. We own a property in College Park, Georgia, that mines bitcoin through immersion technology and two fully constructed parcels of land in Cheyenne, Wyoming, that operate as immersion bitcoin mining facilities. On October 27, 2025, we acquired property in Texas supported by long-term power supply agreements to enable future data-center development. Our leases have expiration dates between March 2026 and June 2039.

We believe our existing facilities and equipment are in good operating condition and are suitable for the conduct of our business. Please refer to the discussions contained in our Item 1. – “Business” for additional information.

Risk factors and legal proceedings

The risks CleanSpark names in Item 1A of its 10-K filed Nov 25, 2025: 77 risks under these headings, as written.8

  • We are subject to various risks that may materially harm our business, prospects, financial condition and results of operations. An investment in our common stock is speculative and involves risk. In evaluating an investment in shares of our common stock, you should carefully consider the risks described below, together with the other information included in this Annual Report on Form 10-K.
  • Risks Related to Our Business
  • Risks Related to Governmental Regulation and Enforcement Operations
  • Risks Related to Our Securities
  • Our future success is difficult to predict because we operate in emerging and evolving industries that are subject to volatile and unpredictable cycles.
  • The markets in which we participate are highly competitive, and as we enter new markets, we are competing against companies with greater resources and capitalization.
  • We have an evolving business model and strategy, which includes an increasing focus on diversifying into constructing and operating data centers for AI and HPC companies, in addition to our bitcoin activities.
  • Our expansion into AI and HPC may divert resources from our core bitcoin mining operations, limit our power capacity for mining, and introduce operational complexity.
  • It may take significant time and expenditure to develop an AI and HPC hosting business through continued development at our facilities, and our efforts may not be successful.
  • We have engaged in, and in the future may engage in, strategic acquisitions and other arrangements that could disrupt our business, cause dilution to our stockholders, reduce our financial resources and harm our operating results.
  • A significant part of our success will depend on our reliance on and ability to manage our construction contractors and suppliers, including mining equipment suppliers, in order to meet our expansion efforts in keeping with planned timelines and cost estimates, and any failure to do so could materially and adversely affect our results of operations and relations with our customers.
  • We rely heavily on our management team, whose continued service and performance are critical to our future success. Any failure by management to properly manage growth, including hiring and retaining competent and skilled management and other personnel, could have a material adverse effect on our business, operating results and financial condition.
The other 68 risks
  • We may not be able to timely complete our future strategic growth initiatives or within our anticipated cost estimates, if at all.
  • We may experience increased compliance costs as a result of future strategic acquisitions.
  • In the future, we may require additional financing to sustain and expand our operations, and we may not be able to obtain financing on acceptable terms, or at all, which would have a material adverse effect on our business, financial condition, results of operations, cash flow and prospects.
  • Our business expansion into AI and HPC services may be capital intensive and could affect our liquidity, results of operations and financial condition.
  • We maintain our cash at financial institutions, often in balances that exceed federally insured limits.
  • Our ability to achieve profitability is currently dependent on the price of bitcoin, which has historically been volatile.
  • We have a limited operating history and a history of operating losses and negative cash flow, and we may never achieve consistent profitability.
  • The impact of geopolitical and economic events on the demand for bitcoin is uncertain.
  • The value of bitcoin has historically been subject to wide swings, and we are exposed to bitcoin’s price volatility and surrounding risks.
  • The development and acceptance of competing blockchain platforms or technologies may cause consumers to use alternative distributed ledgers or other alternatives.
  • Bitcoin is subject to halving; the reward for successfully solving a block will halve several times in the future and its value may not adjust to compensate us for the reduction in the rewards we receive from our mining efforts.
  • Our reliance on a third-party mining pool service provider for our mining revenue payouts may adversely affect an investment in us.
  • Forks in the bitcoin network may occur in the future, which may affect the value of bitcoins held by us.
  • The open-source structure of the bitcoin network protocol means that the contributors to the protocol are generally not directly compensated for their contributions in maintaining and developing the protocol. A failure to properly monitor and upgrade the protocol could damage the bitcoin network and an investment in us.
  • Banks and financial institutions may not provide banking services, or may cut off services, to businesses that engage in cryptocurrency-related activities.
  • Bitcoins held by us are not subject to FDIC or SIPC protections.
  • Bitcoins we mine or hold for our own account may be subject to loss, theft or restriction on access.
  • If a malicious actor or botnet obtains control of more than 50% of the processing power on the bitcoin network, such actor or botnet could manipulate the network to adversely affect us, which would adversely affect an investment in us.
  • The loss or destruction of private keys required to access our bitcoins may be irreversible. Our loss of access to our private keys or our experience of a data loss relating to our bitcoins could adversely affect an investment in us.
  • The digital asset exchanges on which cryptocurrencies, including bitcoin, trade are relatively new and largely unregulated, and thus may be exposed to fraud and failure. Such failures may result in a reduction in the price of bitcoin and other cryptocurrencies and can adversely affect an investment in us.
  • We may face several risks due to disruptions in the digital asset markets, including but not limited to the risk from depreciation in our stock price, financing risk, risk of increased losses or impairments in our investments or other assets, risks of legal proceedings and government investigations, and risks from price declines or price volatility of digital assets.
  • During periods of market stress and extreme volatility, we may be unable to timely liquidate or hedge our bitcoin or related positions, and exchange-driven liquidations or auto-deleveraging could materially and adversely affect our liquidity, results of operations and financial condition.
  • We may not have adequate sources of recovery if our bitcoin holdings are lost, stolen or destroyed.
  • Our ability to adopt technology in response to changing security needs or trends and reliance on a third party, Coinbase, for custody pose a challenge to the safekeeping of our bitcoin holdings.
  • Any potential use of emerging technologies like AI, machine learning and generative artificial intelligence could lead to unintended consequences and result in reputational harm and litigation.
  • Security threats to us could result in a loss of our bitcoin holdings or damage to our reputation and brand, each of which could adversely affect an investment in us.
  • A loss of confidence in our security systems, or a breach of our security systems, may adversely affect us and the value of an investment in us.
  • Bitcoin transactions are irrevocable and stolen or incorrectly transferred bitcoin may be irretrievable. As a result, any incorrectly executed digital asset transactions could adversely affect an investment in us.
  • We may face risks of Internet disruptions, which could have an adverse effect on not only the price of bitcoin but also our ability to mine bitcoin.
  • A failure or degradation of cloud service providers or other critical Internet infrastructure, including our own, could disrupt our operations and third‑party platforms we rely on, including digital asset exchanges and custodians, and could materially and adversely affect our business, results of operations, cash flows and financial condition.
  • The limited rights of legal recourse available to us expose us and our investors to the risk of loss of our bitcoins for which no person is liable.
  • The sale of our bitcoins to pay for expenses at a time of low bitcoin prices could adversely affect an investment in us.
  • Demand for bitcoin is driven, in part, by its status as a prominent and secure cryptocurrency. It is possible that a cryptocurrency other than bitcoin could have features that make it more desirable to a material portion of the digital asset user base, resulting in a reduction in demand for bitcoin.
  • Our facility costs may exceed our revenues, which could seriously harm our business and adversely impact an investment in us.
  • The properties included in our operations may experience damages, including damages that may not be covered by insurance.
  • We are subject to risks associated with our need for significant electrical power.
  • Increased scrutiny and changing expectations from stakeholders with respect to our ESG practices and the impacts of climate change may result in additional costs or risks.
  • Our operations and profitability may be adversely affected by competition from other methods of investing in cryptocurrencies.
  • From time-to-time, as market conditions change, large holders of bitcoin may sell large amounts all at once into the market, thereby constraining the growth of the price of bitcoin.
  • Potential that, in the event of a bankruptcy filing by a custodian, bitcoin held in custody could be determined to be property of a bankruptcy estate and we could be considered a general unsecured creditor thereof.
  • Since there has been limited precedent set for financial accounting of digital assets, including bitcoin, it is unclear how we will be required to account for transactions involving digital assets.
  • If we fail to grow our hashrate, we may be unable to compete, and our results of operations could suffer.
  • Global economic conditions, including continuing or worsening inflationary issues and associated changes in monetary policy and potential economic recession, and geopolitical events such as the Russia-Ukraine conflict, and the subsequent imposition of sanctions as a result of the Russia-Ukraine conflict, and the Israeli-Palestinian conflict, could adversely affect our business, financial condition and results of operations.
  • Divestitures and discontinued operations could negatively impact our business, and retained liabilities from businesses that we have sold could adversely affect our financial results.
  • Our limited insurance protection exposes us and our stockholders to the risk of loss of our bitcoin for which no person is liable.
  • There are risks in connection with noise pollution and community opposition related thereto that may have a negative effect on our business.
  • There are risks related to technological obsolescence, the vulnerability of the global supply chain for cryptocurrency hardware disruption, potential trade restrictions and difficulty in obtaining new hardware which may have a negative effect on our business.
  • We are exposed to risks relating to our bitcoin treasury function.
  • If regulatory changes or interpretations of our bitcoin mining activities require our registration as an MSB under the regulations promulgated by FinCEN under the authority of the BSA, or otherwise under state laws, we may incur significant compliance costs, which could be substantial or cost-prohibitive. If we become subject to these regulations, our costs in complying with them may have a material adverse effect on our business and the results of our operations.
  • Current regulation regarding the exchange of bitcoins under the CEA by the CFTC is unclear; to the extent we become subject to regulation by the CFTC in connection with our exchange of bitcoin, we may incur additional compliance costs, which may be significant.
  • If the SEC or another regulatory body considers bitcoin to be a security under U.S. securities laws, we may be required to comply with significant SEC registration and/or other requirements.
  • It may be illegal now, or in the future, to mine, acquire, own, hold, sell or use bitcoin or other cryptocurrencies, participate in blockchains or utilize similar cryptocurrency assets in one or more countries, the ruling of which could adversely affect us.
  • Changing environmental regulation and public energy policy may expose our business to new risks.
  • If we fail to qualify for certain state government tax incentives or to comply with local tax regulations, we may suffer financial losses.
  • Future developments regarding the treatment of digital assets for U.S. federal income and applicable state, local and non-U.S. tax purposes could adversely impact our business.
  • Our interactions with the bitcoin network may expose us to SDN or blocked persons or cause us to violate provisions of law that did not contemplate distributed ledger technology.
  • The U.S. political and economic environment could materially impact our business operations and financial performance, and uncertainty surrounding the potential legal, regulatory and policy changes by the current U.S. presidential administration may directly affect us and the global economy.
  • Regulations and taxes that target energy could increase our costs and adversely affect our business.
  • Regulatory developments surrounding AI and HPC may negatively impact our efforts to expand into AI and HPC hosting.
  • The price of our common stock may be volatile and could fluctuate widely, which could result in substantial losses for investors.
  • We have the right to designate and issue additional shares of preferred stock. If we were to designate and/or issue additional preferred stock, it is likely to have rights, preferences and privileges that may adversely affect the common stock.
  • We are currently the subject of a shareholder class action, and may be subject to shareholder litigation in the future; our costs of defending such litigation, arbitration and other proceedings and any adverse outcome of such litigation, arbitration or other proceeding may have a material adverse effect on our business and the results of our operations.
  • We have financed our strategic growth primarily by issuing new shares of our common stock and convertible debt in public offerings, which dilutes the ownership interests of our current stockholders, and which may adversely affect the market price of our securities.
  • We have not paid dividends on shares of our common stock in the past and have no immediate plans to do so in the future.
  • If securities or industry analysts do not publish or do not continue to 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.
  • Our indebtedness could adversely affect our financial health and prevent us from fulfilling our debt obligations.
  • We incur significant costs and demands upon management and accounting and finance resources as a result of complying with the laws and regulations affecting public companies; any failure to establish and maintain adequate internal controls and/or disclosure controls or to recruit, train and retain necessary accounting and finance personnel could have an adverse effect on our ability to accurately and timely prepare our financial statements and otherwise make timely and accurate public disclosure.
  • Provisions in the Nevada Revised Statutes and our bylaws could make it very difficult for an investor to bring any legal actions against our directors or officers for violations of their fiduciary duties or could require us to pay any amounts incurred by our directors or officers in any such actions.

Legal proceedings

For a description of our material pending legal proceedings, refer to Note 19 - Commitments and Contingencies included in our notes to Consolidated Financial Statements.

We are subject to other legal proceedings and claims that have not been fully resolved and that have arisen in the ordinary course of business. We routinely are subject to and resolve matters that do not individually or in the aggregate have a material impact on our financial condition or operating results. The outcome of litigation is inherently uncertain. If one or more legal matters were resolved against us in a reporting period for amounts above management’s expectations, our financial condition and operating results for that reporting period could be materially adversely affected.
