YoY shift: Unscored

Year-over-year tone shift - average net-tone change across Risk Factors and MD&A vs the prior 10-K.

Why YoY instead of absolute: the LM lexicon has ~6.6× more negative words than positive (legal/risk-disclosure language is heavy on hedging), so every 10-K reads bearish on raw tone. Year-over-year change strips that bias and surfaces the actual shift in management's framing.

ITEM 1A. Risk Factors

Our business faces many risks. Before deciding whether to invest in our common stock, you should carefully consider the risk factors discussed in this Annual Report. If any of the risks or uncertainties described herein actually occurs, our business, financial condition, results of operations or cash flow could be materially and adversely affected. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment. The risks and uncertainties we have described are not the only ones facing our company. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business operations.

Risks Related to Our HPC and Data Center Business

Our HPC business strategy may not perform as planned.

We believe the potential for HPC hosting complements our current business model with expected stable, long-term and high margin revenue. However, the success of our HPC hosting services may not develop as anticipated, and may be affected by factors such as the reliability and timing of power supply, supply chain disruption (including local labor availability), the implementation of new tariffs and more restrictive trade regulations and changes in in-house specialized expertise to manage the business. A failure to successfully implement our HPC business strategy may adversely affect our business, prospects, or operations.

If we are unable to complete our data center campuses and future strategic growth initiatives in a timely manner or within anticipated cost estimates, our business and results of operations could be adversely affected.

Our business depends upon the completion and build-out of our HPC and AI-focused data center campuses (including the Lake Mariner Data Campus and the Abernathy HPC Campus) and other future strategic growth initiatives. Until we complete construction of the facilities required by our customer leases and hosting agreements, we will not realize the full amount of projected revenue from those leases. While our present expansion projects are proceeding on track with our expectations, we cannot guarantee we will complete these expansions or future strategic growth initiatives on time or within our anticipated cost estimates, if at all, due in part to ongoing challenges to the global supply chain, the implementation of new tariffs and more restrictive trade policies, increased inflation, and changing conditions within the United States labor market.

The expansion and build-out of our data center campuses expose us to significant construction risks, including risks related to construction delays; lack of availability of parts and/or labor; increased prices; labor disputes and work stoppages; unanticipated environmental issues and geological problems; delays related to permitting and approvals from public agencies and utility companies; and delays in site readiness leading to our failure to meet commitments. Construction-related projects depend on the skill, experience, and performance of designers, contractors, subcontractors and key suppliers. Should any such party experience financial difficulties or other problems, we could experience significant delays, increased costs and other negative impacts to our expected returns.

Delays in lease commencement, limitations in customer backstop arrangements and the potential insufficiency of completion guarantees could adversely affect our financial condition and results of operations.

Under certain circumstances, lessees may have the right to terminate applicable leases if there are significant delays in construction, subject to extension for force majeure events. We and certain affiliated entities have agreed to provide subsidiaries with funds necessary to achieve target commencement dates under applicable customer leases; however, these completion guarantees may not be sufficient. If we are unable to complete projects within anticipated cost

Table of Contents

estimates, we may not have sufficient funds to provide necessary support. The failure to complete projects in a timely manner could have a material adverse effect on our financial condition and results of operations.

Customer backstop arrangements of obligations under certain leases (for example, Google’s Backstop of Fluidstack’s obligations under the applicable Fluidstack Leases) are only effective following the commencement of the relevant lease. If one or more leases do not commence as of their respective targeted commencement dates, then the corresponding backstop may not become effective until completion of the applicable project. If completion of a data center campus is delayed beyond specified thresholds, the customer may have the right to terminate the applicable lease. Such termination event would not trigger the backstop. In addition, backstop arrangements are only triggered upon a payment or insolvency event of default under the applicable lease. There are other events of default or termination events that may result in the termination of a lease without triggering the applicable backstop. In addition, if we have a disagreement about whether a backstop has been triggered, there can be no assurance that such backstop will be honored in a timely manner or at all.

We may be harmed by increased costs to procure power, prolonged power and internet outages, shortages or capacity constraints as well as insufficient access to power.

Our bitcoin mining and HPC data center operations require a significant amount of electrical power and access to high-speed internet to be successful. Any power and internet outages, shortages, capacity constraints or significant increases in the cost of power may have an adverse effect on our business and our results of operations, including our mining and data center operations.

We rely on third parties, third party infrastructure, governments, and global supplies to provide a sufficient amount of power to maintain our bitcoin mining and HPC data center operations to meet the needs of our current and future HPC hosting and colocation customers. Any limitation on the delivered energy supply could limit our ability to operate our bitcoin mining and HPC data centers. These limitations could have a negative impact on our existing data center campuses or limit our ability to grow our business, which could negatively affect our financial performance and results of operations. Each new HPC data center requires access to significant quantities of electricity. Limitations on generation, transmission and distribution may limit our ability to obtain sufficient power capacity for potential expansion sites or existing markets. Utility companies may impose onerous operating conditions to any approval or provision of power or we may experience significant delays and substantial increased costs to provide the level of electrical service required by our current or future data center designs.

Our ability to successfully develop projects is impacted by the availability of, and access to, interconnection facilities and transmission systems.

In recent years, the time and costs required to secure and expand interconnection facilities and transmissions systems have increased, complicating project planning and creating additional contractual and financial risk for projects under construction. We may face difficulties in expanding our interconnection facilities and access to transmissions systems in a timely manner and at a reasonable cost as well as curtailment resulting from transmission facility downtime, which could materially and adversely affect our results of operations and cash flow.

Since the development, construction and operation of the Abernathy HPC Campus is subject to the terms of a joint venture agreement, TeraWulf may have less control over strategic decisions.

On October 27, 2025, the TeraWulf Member entered into the Abernathy Joint Venture Agreement with the Fluidstack Member. The Abernathy Joint Venture Agreement provides that, except for certain specified matters, decisions are to be made by a majority vote of the board of managers. The board of managers will initially comprise three designees of TeraWulf and two designees of the Fluidstack Member. Any significant disagreements between joint venture partners on strategic decisions or the inability of the Fluidstack Member to meet obligations to the Abernathy Joint Venture or third parties may impede TeraWulf’s ability to control aspects of the development, construction, and operation of the Abernathy HPC Campus.

We depend on significant customers for our HPC data centers.

Many factors, including global economic conditions, may cause our HPC data center customers to experience a downturn in their businesses or otherwise experience a lack of liquidity, which may weaken their financial condition and impact our estimates as to the probability of collectability of payments, and ultimately result in their failure to make timely rental and other payments or their default under their agreements with us. Further, the development of new technologies, the adoption of new industry standards or other factors could render our HPC data center customers’ current products and

Table of Contents

services obsolete or unmarketable and contribute to a downturn in their businesses, thereby increasing the likelihood that they default under their leases, become insolvent or file for bankruptcy. If a customer defaults or fails to make timely rent or other payments, we may experience delays in enforcing our rights as landlord and may incur substantial costs in protecting our investment, which could adversely affect our financial condition and results of operations.

If a customer becomes a debtor in a case under the U.S. Bankruptcy Code, we cannot evict the customer solely because of the bankruptcy. In addition, the bankruptcy court might authorize the customer to reject and terminate its contracts with us. Our claim against the customer for unpaid, future rent and other payments would be subject to a statutory cap that might be substantially less than the remaining amounts actually owed under their agreements with us. In either case, our claim for unpaid rent and other amounts would likely not be paid in full. Our revenue could be materially adversely affected if a significant customer were to become bankrupt or insolvent, suffer a downturn in its businesses, fail to renew its contract or renew on terms less favorable to us than its current terms.

Our contracts with HPC data center customers could subject us to significant liability.

In the ordinary course of business, we aim to continuously enter into agreements with customers pursuant to which we provide data center space, power, environmental controls, physical security and connectivity products to our HPC hosting and colocation customers. These contracts typically contain indemnification and liability provisions, in addition to service level commitments, which could potentially impose a significant cost on us in the event of losses arising out of certain breaches of such agreements, services to be provided by us or our subcontractors or from third-party claims. HPC data center customers increasingly are looking to pass through their regulatory obligations and other liabilities to their outsourced data center providers and we may not be able to limit our liability or damages in an event of loss suffered by such customers whether as a result of our breach of an agreement or otherwise. If such an event of loss occurred, we could be liable for material monetary damages and could incur significant legal fees in defending against such an action, which could adversely affect our financial condition and results of operations.

We may also develop space specifically for HPC data center customers pursuant to agreements signed prior to beginning or early in the development process. In those cases, if we fail to meet our development obligations under those agreements, these customers may be able to terminate their agreements and we would be required to find a new customer for this space. In addition, in certain circumstances we may lease HPC data center facilities prior to their completion. If we fail to complete the facilities in a timely manner, the customer may be entitled to terminate its agreement, seek damages or penalties against us or pursue other remedies and we may be required to find a new customer for the space. If we are not able to complete an HPC data center in a timely manner, if development costs are higher than we currently estimate, our financial condition, results of operations and cash flow could be materially adversely affected.

Additionally, a customer’s decision to lease space and power in our HPC data center typically involves a significant commitment of resources and due diligence on the part of our customers regarding the adequacy of our facilities. As a result, we may expend significant time and resources in pursuing a particular transaction that may not result in revenue. Economic conditions, including market downturns and the implementation of new tariffs and more restrictive trade regulations may impact customers’ ability to plan future business activities, which could cause customers to slow spending or delay decision-making. Our inability to adequately manage the risks associated with these developments may adversely affect our business, financial condition and results of operations.

Certain of our agreements with HPC data center customers may include restrictions on providing HPC hosting and colocation services to certain third parties, which could have a material adverse effect on us.

Certain of our customer agreements may prohibit us from providing HPC hosting and colocation services to certain third parties, including competitors of existing HPC data center customers. The existence of such restrictions could hinder our ability to enter into agreements with additional HPC data center customers, which could materially adversely affect our business, financial condition and results of operations.

We may be unable to access sufficient additional capital for future strategic growth initiatives, and any such capital raises may be dilutive or subject to restrictive terms.

The expansion of our digital infrastructure to support HPC hosting and colocation and our future strategic growth initiatives are capital-intensive. We expect to raise additional capital to fund these initiatives; however, we may be unable to do so in a timely manner, in sufficient quantities, or on terms acceptable to us, if at all. If we raise additional equity financing, our stockholders may experience dilution of their ownership interests, and the per share value of our common stock could decline.

Table of Contents

If we engage in debt financing, 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 and may require us to accept restrictive covenants. If we are unable to generate sufficient cash flows from operations to support our strategic growth, we may be required to reduce or delay investments, sell assets, or obtain financing on terms that may be onerous or highly dilutive.

Failure to successfully integrate acquired businesses could negatively impact our balance sheet and results of operations.

Strategic acquisitions and/or combinations are a component of our growth strategy and the success of any acquisition we make depends in part on our ability to integrate the acquired business and realize anticipated synergies. Integrating acquired businesses may involve unforeseen difficulties, may require a disproportionate amount of our management’s attention, and may require us to reallocate our resources, financial or otherwise.

For example, we may encounter challenges in the integration process such as: difficulties associated with managing the resulting larger and more complex company; conforming administrative and corporate structures and standards, controls, procedures and policies, business cultures, hiring and retention of key employees, and compensation and benefits structures, coordinating geographically dispersed operations; and our ability to deliver on our strategy going forward.

Further, our acquisitions may subject us to new liabilities and risks, some of which may be unknown. Although we and our advisors conduct due diligence on the operations of businesses we consider acquiring, there can be no guarantee that we are aware of all the liabilities of an acquired company. These liabilities, and any additional risks and uncertainties related to an acquired company not known to us or that we may deem immaterial or unlikely to occur at the time of the acquisition, could negatively impact our future business, financial condition, and results of operations.

We can give no assurance that we will ultimately be able to effectively integrate and manage the operations of any acquired business or realize anticipated synergies. The failure to successfully integrate the cultures, operating systems, procedures and information technologies of an acquired business could have a material adverse effect on our financial condition and results of operations.

We may experience increased compliance costs as a result of our strategic acquisitions.

Future strategic acquisitions could carry substantial compliance burdens, which may limit our ability to realize the anticipated benefits of such acquisitions, and which may require our management and personnel to shift their focus to such compliance burdens and away from their other functions. Such increased costs and compliance burdens could affect our ability to realize the anticipated benefits of such strategic acquisitions, and our business, results of operations, and financial condition may suffer as a result.

The development and advancement in the efficiency of AI models presents risks and challenges that may adversely impact our business and operating results.

The introduction of, and advancement in the efficiency of AI models could potentially adversely affect data center usage by significantly reducing the computational power needed to train AI models, potentially leading to less demand for high-power density, liquid-cooled data center infrastructure and colocation facilities. New advancements in AI models could also alter the way data centers are currently designed and utilized and may adversely affect our business and results of operations.

Cyber-attacks, data breaches or malware may disrupt our operations and trigger significant liability for us, which could harm our operating results and financial condition, and damage our reputation or otherwise materially harm our business.

As a publicly traded company, at times we experience cyber-attacks, such as phishing, and other attempts to gain unauthorized access to our systems, and we anticipate continuing to be subject to such attempts. There is an ongoing risk that some or all of our bitcoin or customer or Company data could be lost or stolen as a result of one or more of these incursions. As we increase in size, we may become a more appealing target of hackers, malware, cyber-attacks or other security threats, and, despite our implementation of strict security measures, it is impossible to eliminate all such vulnerability. For instance, we may not be able to ensure the adequacy of the security measures employed by third parties, such as our service providers. Additionally, though we provide cybersecurity training for all employees, we cannot guarantee that we will not be affected by further phishing attempts. Efforts to limit the ability of malicious actors to disrupt the operations of the internet or undermine our own security efforts may be costly to implement and may not be successful.

Table of Contents

Such breaches, whether attributable to a vulnerability in our systems or otherwise, could result in claims of liability against us, damage our reputation and materially harm our business.

We are currently making considerable investments in our information technology systems and processes. Difficulties from or disruptions to these efforts may interrupt our normal operations and adversely affect our business and results of operations.

We have been making considerable investments in our information technology systems and processes and expect such investment to continue for the foreseeable future in support of our bitcoin mining operations and our expansion into HPC hosting and colocation. These continuing investments and upgrades include the implementation of new tools and technologies to further streamline and automate processes, including with respect to procurement, and to support our compliance with evolving U.S. GAAP. These investments and upgrades and may take longer to complete and cost more than originally planned. As a result of our continued work on these projects, we may experience difficulties with our systems and business disruptions. Any such difficulties or disruptions may adversely affect our business and results of operations.

We depend on attracting and retaining officers, managers, and skilled professionals.

Our success depends, in large part, on our ability to hire, retain and motivate talented officers, leadership, and professionals. We cannot guarantee that such employees will be retained which may inhibit our management functions, strategic development, and other critical functions. Our growth may be constrained by human capital resource limitations as we compete with other companies for skilled employees. We will need to take strategic action to develop our pool of management and skilled employees as well as grow such pool to meet the demands of our corporate functions. If we are not able to do so, our business, and thus our ability to grow, may be materially adversely affected.

Enhanced tariff, import/export restrictions, or other trade barriers may have an adverse impact on global economic conditions.

There have been, and continue to be, uncertainties with respect to the global economy and trade relations between the U.S. and other countries globally, including trade policies, treaties, tariffs, and customs duties and taxes. Implementation of more restrictive trade policies or the renegotiation of existing U.S. trade agreements or trade agreements of other countries where we procure supplies and materials for our digital infrastructure could negatively impact our business results of operations, cash flows, and financial condition. Tariffs, sanctions and other barriers to trade could adversely affect the business of our customers and suppliers, which could in turn negatively impact our net revenue and results of operations. If tariffs, trade restrictions or trade barriers are expanded or increased, then our exposure to future taxes and duties on imported products and components could be significant and could have a material effect on our financial results.

We cannot predict the extent to which the U.S. or other countries will impose new or additional quotas, duties, tariffs, taxes, or other similar restrictions upon the import of goods and services in the future, nor can we predict future trade policy or the terms of any renegotiated trade agreements and their impact on our business. The continuing adoption or expansion of trade restrictions, the occurrence of a trade war, or other governmental action related to tariffs or trade agreements or policies has the potential to adversely impact demand for our HPC data centers, our costs, our customers, our suppliers, and the U.S. economy, which in turn could have a material adverse effect on our business, operating results, and financial condition.

Increased scrutiny and changing expectations from stakeholders with respect to our environmental, social, and governance (ESG) practices and the impacts of climate change may result in additional costs or risks.

Companies across many industries are facing increasing scrutiny related to their ESG practices. Investor advocacy groups, certain institutional investors, investment funds and other influential investors are also increasingly focused on ESG practices and in recent years have placed increasing importance on the non-financial impacts of their investments. Furthermore, increased public awareness and concern regarding environmental risks, including global climate change, has resulted in and may continue to result in increased public scrutiny of our business and our industry, and our management team may divert significant time and energy away from our operations and towards responding to such scrutiny and reassuring our employees.

In addition, the physical risks of climate change may impact the availability and cost of materials and natural resources, sources and supply of energy, demand for bitcoin and other cryptocurrencies, and could increase our insurance and other operating costs, including, potentially, to repair damage incurred as a result of extreme weather events or to

Table of Contents

renovate or retrofit facilities to better withstand extreme weather events. If environmental laws or regulations or industry standards are either changed or adopted and impose significant operational restrictions and compliance requirements on our operations, or if our operations are disrupted due to the physical impacts of climate change, our business, capital expenditures, results of operations, financial condition and competitive position could be negatively impacted.

We have a history of operating losses, and we may report additional operating losses in the future.

We have recorded historical losses and negative cash flows from our operations, including from our bitcoin mining activities when the value of bitcoin mined did not exceed our associated costs. As we transition an increasing portion of our business toward HPC hosting and colocation, we are making substantial capital investments in developing and expanding our data center campuses. These investments are capital-intensive and revenue from HPC hosting is dependent upon the completion and commencement of customer leases. Future market prices of bitcoin remain difficult to predict, and demand for HPC hosting services may not develop as anticipated. There can be no assurance that revenue from our bitcoin mining operations and HPC data center operations will exceed our associated operating and capital costs.

Risks Related to the Bitcoin Mining Business

Our ability to achieve profitability is largely dependent on the price of bitcoin, which has historically been volatile.

Our existing bitcoin mining operations are largely based on our assumptions regarding the future value of bitcoin, which has been subject to significant historical volatility and may be subject to influence from malicious actors, real or perceived scarcity of bitcoin, political, economic, and regulatory conditions and speculation making bitcoin’s price more volatile or creating “bubble” type risks for the trading price of bitcoin. Further, unlike traditional stock exchanges, which have listing requirements and vet issuers, requiring companies to comply with rigorous listing standards and rules, which monitor transactions for fraud and other improprieties, markets for bitcoin and other cryptocurrencies tend to be unregulated or underregulated. In general, less stringent markets are perceived to have a higher risk of fraud or manipulation and any lack of oversight or perceived lack of transparency could reduce confidence in the price of bitcoin and other cryptocurrencies, which could adversely affect the price of bitcoin. Bitcoin and crypto asset markets generally may be subject to increased scrutiny and regulation by the U.S. legislature and government agencies, and such evolving regulatory and legal environment may impact our bitcoin mining activities and therefore an impact on our business.

These factors make it difficult to accurately predict the future market price of bitcoin and may also inhibit consumer trust in, and market acceptance of, cryptocurrencies as a means of exchange, which could limit the future adoption of bitcoin and, as a result, our assumptions could prove incorrect. If our assumptions prove incorrect and the future price of bitcoin is not sufficiently high, our revenue from our bitcoin mining operations may not exceed our costs, and our operations may not be profitable, which would have a material adverse effect on our results of operations and financial condition.

Instability, fraud, or failures within the broader cryptocurrency ecosystem may adversely affect the price of bitcoin and our results of operations.

Digital asset exchanges and cryptocurrency platforms are relatively new and, in many cases, lightly regulated. Certain exchanges have filed for bankruptcy or become subject to investigation by governmental agencies for fraud or other misconduct, resulting in increased volatility and loss of confidence in digital asset markets. Bitcoin is subject to price volatility resulting from financial instability, poor business practices, fraudulent activities of participants in the broader cryptocurrency market and heightened regulatory scrutiny.

A perceived lack of stability in the digital asset exchange market, the closure or temporary shutdown of exchanges due to business failure, cyber-attacks, government-mandated regulation or fraud, or other disruptions in the cryptocurrency ecosystem may reduce confidence in digital asset networks and result in greater volatility in bitcoin values. Such developments could adversely affect our bitcoin mining operations and our financial condition.

Bitcoin is subject to halving, and our bitcoin mining operations may generate less revenue as a result.

The number of new bitcoin awarded for solving a block is cut in half at mathematically predetermined intervals, known as “halving”. The next halving for the bitcoin blockchain is currently anticipated to occur in April 2028. While bitcoin prices have historically increased around these halving events, there is no guarantee that the price change will be favorable or would compensate for the reduction in mining rewards. If a corresponding and proportionate increase in the price of bitcoin does not follow future halving events, the revenue we earn from our bitcoin mining operations would see a decrease, which could have a material adverse effect on our results of operations and financial condition.

Table of Contents

Because our miners are designed specifically to mine bitcoin and may not be readily adaptable to other uses, a sustained decline in bitcoin’s value could adversely affect our business and results of operations.

We have invested substantial capital in acquiring miners using ASIC chips designed specifically to mine bitcoin using the 256-bit secure hashing algorithm (“SHA-256”) 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 bitcoin mining operations focus exclusively on mining bitcoin, and our bitcoin mining revenue is based on the value of the bitcoin we mine. 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 may not be able to mine, the revenue we generate from our bitcoin mining operations will likewise decline. Moreover, because our miners use these highly specialized ASIC chips, we may not be able to successfully repurpose them in a timely manner, if at all, to other uses, following a sustained decline in bitcoin’s value or if the bitcoin blockchain stops using SHA-256 for solving blocks. This would result in a material adverse effect on our business and could potentially impact our ability to continue as a going concern.

Our reliance on third-party miners may subject our operations to increased risk of design flaws.

The performance and reliability of our miners and our technology is critical to our reputation and our operations. We currently predominantly use Bitmain Technologies Limited (“Bitmain”) miners, and if there are issues with those machines, such as a design flaw in the ASIC chips they employ, our system could be substantially affected. Any system error or failure may significantly delay response times or even cause our system to fail. Any disruption in our ability to continue mining could result in lower yields and harm our reputation and business. Any exploitable weakness, flaw, or error common to the Bitmain miners we currently utilize could affect substantial portions of our miners; therefore, if a defect or other flaw exists and is exploited, a majority of, or all of our miner fleet could be adversely impacted. Any interruption, delay or system failure could result in financial losses, a decrease in the trading price of our common stock and damage to our reputation.

Our use of a third-party mining pool exposes us to certain risks.

We receive bitcoin rewards from our mining activity through a third-party mining pool operator, Foundry. Mining pools allow miners to combine their processing power, increasing their chances of solving a block and getting paid by the network. The rewards are distributed by the pool operator, proportionally to our contribution to the pool’s overall mining power, after deducting the applicable pool fee, if any, used to solve a block on the bitcoin blockchain. Should the pool operator’s system suffer downtime due to a cyber-attack, software malfunction or other issue, it could negatively impact our ability to mine and receive revenue, if we are unable to quickly switch to another pool or to self-mine without a pool. Furthermore, it is possible that the mining pool operator could fail to accurately record the total processing power provided to the pool for a given bitcoin mining application, which would inhibit our ability to confirm the proportion of that total processing power which we provided. While we have internal methods of tracking both the hash rate we provide and the total used by the pool, the mining pool operator uses its own record-keeping to determine our proportion of a given reward, which may not match our own. If we are unable to consistently obtain accurate proportionate rewards from our mining pool operator, we may not receive accurate block rewards from the pool, and we would have limited recourse to correct these inaccuracies. This could lead us to decide against further participation in a mining pool, or mining pools generally, which may affect the predictability of our mining returns, which could have an adverse effect on our business and operations.

If Foundry were to cease operations, there would be some delay and consequently lost revenue until we pointed our miners at our backup pool provider, which we would do by using a mass command issued with our management software. Furthermore, while we receive daily reports from Foundry detailing the total processing power provided to its mining pool and our proportion of that total processing power to determine the distribution of rewards to us, we are dependent on the accuracy of Foundry’s record keeping. We have little means of recourse against Foundry if we determine the proportion of the reward paid out to us by Foundry is incorrect, other than leaving Foundry’s pool altogether. If we are unable to consistently obtain accurate proportionate rewards from our pools, we may experience reduced rewards for our efforts, which would have an adverse effect on our business and operations. Additionally, were Foundry to cease operations, declare insolvency or file for bankruptcy, there is a reasonable risk that recovery of any mining rewards or fees for any given day that had not yet been delivered into our wallet held at NYDIG would be delayed or unrecoverable.

We may not be able to realize the benefits of forks.

The bitcoin blockchain is subject to modification based on a consensus of the users on its network. When a significant minority of users on the network agree to a modification that is not compatible with the prior network protocol, a “fork” of the network results, with one prong running the pre-modified protocol and the other running the modified

Table of Contents

protocol. The effect of such a fork would be the existence of two “versions” of the blockchain running in parallel that are not interchangeable, which requires exchange-type transactions to convert between the two forks. Additionally, it may be unclear following a fork which of the two protocols represents the original and which is the new protocol. Different metrics adopted by industry participants to determine which is the original asset following a fork in the bitcoin blockchain may include: referring to the blockchain with the greatest network hash rate, or to the “length” of blockchain (i.e., the time between the first transaction recorded in the blockchain’s distributed ledger and the date of the most recent transaction). Accordingly, it is possible that a fork may occur on the bitcoin blockchain that results in an asset different from our current bitcoin holdings, or a protocol different from SHA-256 (which our miners are specifically designed to operate), gaining predominance, and the value of our bitcoin assets may suffer, or we may not be able to adapt our miners to the new protocol. Therefore, we may not realize the economic benefit of a fork in the bitcoin blockchain, either immediately or ever, which could adversely affect an investment in our securities.

Incorrect or fraudulent bitcoin transactions may be irreversible and we could lose access to our bitcoin.

Bitcoin transactions are not, from an administrative perspective, reversible without the consent and active participation of the recipient of the bitcoin from the transaction. Because of the decentralized nature of the bitcoin blockchain, once a transaction has been verified and recorded in a block that is added to the bitcoin blockchain, an incorrect transfer of a bitcoin or a theft thereof generally will not be reversible, and we may not have sufficient recourse to recover our losses from any such transfer or theft. It is possible that, through computer or human error, or through theft or criminal action, our bitcoin rewards could be transferred in incorrect amounts or to unauthorized third parties, or to uncontrolled accounts. Though recent high profile enforcement actions against individuals laundering stolen bitcoin have demonstrated some means of bringing malicious actors to justice for their theft, the stolen bitcoin is likely to remain unrecoverable. Furthermore, we utilize a third-party custodian for our bitcoin, and thus do not maintain a private key. However, if they lose access to our wallet, or if a malicious actor successfully denies the third-party custodian access to our wallet, we may be permanently denied access to the bitcoin held in the wallet corresponding to the lost, stolen or blocked keys. Though we have taken and continue to take reasonable steps to secure our data and to store our bitcoin with an institutional custodian, if we, or our third-party custodian were to experience data loss relating to our digital wallets, we could effectively lose access to and the ability to use our bitcoin assets. Moreover, we may be unable to secure insurance policies for our bitcoin assets at rates or on terms acceptable to us, if at all, and we may choose to self-insure. To the extent that we are unable to recover our losses from such action, error or theft, such events could have a material adverse effect on our business, results of operations and financial condition.

Digital assets held by the Company are not subject to FDIC or SIPC protections.

The Company does not hold its digital assets with a banking institution or a member of the Federal Deposit Insurance Corporation (“FDIC”) or the Securities Investor Protection Corporation (“SIPC”) and, therefore, its digital assets are not subject to the protections enjoyed by depositors with FDIC or SIPC member institutions.

Risks Related to Governmental Regulation and Enforcement

We are subject to a highly-evolving regulatory landscape and any adverse changes to, or our failure to comply with, any laws and regulations could adversely affect our business, reputation, prospects or operations.

As cryptocurrencies have grown in both popularity and market size, governments around the world have reacted differently to cryptocurrencies; certain governments have deemed them illegal, and others have allowed their use and trade without restriction, while some jurisdictions, such as the United States, subject the mining, ownership and exchange of cryptocurrencies to certain, and in some cases overlapping, unclear and evolving regulatory requirements.

We currently only operate in the United States, and do not currently have any plans to expand our operations beyond the United States. As bitcoin has grown in popularity and in market size, the U.S. regulatory regime, namely the Federal Reserve Board, U.S. Congress and certain U.S. agencies (e.g., the SEC, the CFTC, FinCEN and the Federal Bureau of Investigation) have begun to examine the operations of the bitcoin network, bitcoin users and the bitcoin exchange market. The complexity and evolving nature of our business and the significant uncertainty surrounding the regulation of the cryptocurrency industry requires us to exercise our judgment as to whether certain laws, rules, and regulations apply to us, and it is possible that governmental bodies and regulators may disagree with our conclusions. To the extent we have not complied with such laws, rules, and regulations, we could be subject to significant fines, revocation of licenses, limitations on our products and services, reputational harm, and other regulatory consequences, each of which may be significant and could adversely affect our business, operating results, and financial condition.

Potentially increasing regulation and regulatory scrutiny may result in new costs for the Company and Company’s management having to devote increased time and attention to regulatory matters, change aspects of the Company’s business or result in limits on the utility of bitcoin. In addition, regulatory developments and/or the Company’s business activities may require the Company to comply with certain regulatory regimes. Increasingly strict legal and regulatory requirements and any regulatory investigations and enforcement may result in changes to our business, as well as increased costs, and supervision and examination for ourselves and our service providers. Ongoing and future regulation and regulatory actions could also significantly restrict or eliminate the market for or uses of bitcoin and/or may adversely affect the Company’s business, reputation, financial condition and results of operations. Moreover, new laws, regulations, or interpretations may result in additional litigation, regulatory investigations, and enforcement or other actions. Adverse changes to, or our failure to comply with, any laws and regulations may have an adverse effect on our reputation and brand and our business, operating results, and financial condition.

Bitcoin and bitcoin mining, as well as cryptocurrencies generally, may be made illegal in certain jurisdictions, including the ones we operate in, which could adversely affect our business prospects and operations.

It is possible that state or federal regulators may seek to impose harsh restrictions or total bans on bitcoin mining which may make it impossible for us to do business without relocating our mining operations, which could be very costly and time consuming. Further, although bitcoin and bitcoin mining, as well as cryptocurrencies generally, are largely unregulated in most countries (including the United States), regulators could undertake new or intensify regulatory actions that could severely restrict the right to mine, acquire, own, hold, sell, or use cryptocurrency or to exchange it for traditional fiat currency such as the United States Dollar. Such restrictions may adversely affect us as the large-scale use of bitcoin as a means of exchange is presently confined to certain regions globally. Such circumstances could have a material adverse effect on us, which 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 thus harm investors.

Changing environmental regulation and public energy policy may expose our business to new risks.

Our bitcoin mining and HPC data center operations require a substantial amount of power and can only be successful, and ultimately profitable, if the costs we incur, including for electricity, are lower than the revenue we generate from our operations. As a result, any bitcoin mining and HPC data center facility we establish can only be successful if we can obtain sufficient electrical power for that facility on a cost-effective basis, and our establishment of new facilities requires us to find locations where that is the case. If new regulations are imposed, or if existing regulations are modified, the assumptions we made underlying our plans and strategic initiatives may be inaccurate, and we may incur additional costs to adapt our planned business, if we are able to adapt at all, to such regulations.

In addition, there continues to be a lack of consistent climate legislation, which creates economic and regulatory uncertainty for our business because the bitcoin mining industry, with its energy demand, may become a target for future environmental and energy regulation. New legislation and increased regulation regarding climate change could impose significant costs on us and our suppliers, including costs related to increased energy requirements, capital equipment, environmental monitoring and reporting, and other costs to comply with such regulations. Further, any future climate change regulations could also negatively impact our ability to compete with companies situated in areas not subject to such limitations.

Moreover, in the State of New York, we currently participate in energy demand response programs to curtail operations, return capacity to the electrical grid, and receive funds to offset foregone operational mining revenue when necessary, such as in extreme weather events. Furthermore, we, as well as other bitcoin miners, received a mandatory survey from the U.S. Energy Information Administration (the “EIA”), seeking extensive information regarding our facilities’ use of electricity, and certain information regarding our operations, solely for the month of January 2024. This request was subsequently withdrawn by the EIA; however, it is possible that mandatory surveys such as this will be used by the EIA to generate negative reports regarding the bitcoin mining and HPC data center industries’ use of power and other resources, which could spur additional negative public sentiment and adverse legislative and regulatory action against us or the bitcoin mining and HPC data center industries as a whole. Surveys and other regulatory actions could increase our cost of operations or otherwise make it more difficult for us to operate at our current locations.

Given the political significance and uncertainty around the impact of climate change and how it should be addressed, and energy disclosure and use regulations, we cannot predict how legislation and regulation will affect our financial condition and results of operations in the future in the United States. However, due to the use of predominantly zero-carbon power in our operations, we believe we are advantageously positioned relative to our competitors in this regard. Further, even without such regulation, increased awareness and any adverse publicity in the global marketplace

Table of Contents

about potential impacts on climate change or energy use by us or other companies in our industry could harm our reputation. Any of the foregoing could result in a material adverse effect on our business and financial condition.

The compliance costs of responding to new and changing regulations could adversely affect our operations.

We are subject to various federal, state and local laws and regulations, including those relating to the generation, storage, handling, and disposal of hazardous substances and wastes. Certain of these laws and regulations also impose joint and several liability, without regard to fault, for investigation and cleanup costs on current and former owners and operators of real property and persons who have disposed of or released hazardous substances into the environment. Our operations may involve the use of hazardous substances and materials, such as petroleum fuel for temporary generators, as well as batteries, cleaning solutions, and other materials.

The course of future legislation and regulation in the United States remains difficult to predict, and potential increased costs associated with new legislation or regulation cannot be estimated at this time.

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

The Office of Financial 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 Company’s policy prohibits any transactions with such SDN individuals, and we take all commercially reasonable steps to avoid such transactions, but we may not be adequately capable of determining the ultimate identity of the individual with whom we transact with respect to selling bitcoin assets. Moreover, there is a risk that some bad actors will continue to attempt to use cryptocurrencies, including bitcoin, as a potential means of avoiding federally imposed sanctions, such as those imposed in connection with the Russian invasion of Ukraine.

We are unable to predict the nature or extent of new and proposed legislation and regulation affecting the bitcoin industry, or the potential impact of the use of bitcoin 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 common stock.

We may be at a higher risk of litigation and other legal proceedings due to heightened regulatory scrutiny of the cryptocurrency industry, which could ultimately be resolved against the Company, requiring material future cash payments or charges, which could impair our financial condition and results of operations.

The size, nature and complexity of the Company’s business could make it susceptible to various claims, both in litigation and binding arbitration proceedings, legal proceedings, and government investigations. The Company believes that since cryptocurrency mining, and the digital asset industry generally, is a relatively new business sector, it is more likely subject to government investigation and regulatory determination. Any claims, regulatory proceedings or litigation that could arise in the course of the Company’s business could have a material adverse effect on the Company, its business or operations, or the industry as a whole.

The Company may be classified as an inadvertent investment company.

The Company is not engaged in the business of investing, reinvesting or trading in securities and does not hold itself out as being engaged in those activities. Under the Investment Company Act, however, a company may be deemed an investment company under Section 3(a)(1)(C) if the value of its investment securities is more than 40% of its total assets (exclusive of government securities and cash items) on a consolidated basis.

The Company will be engaging in digital asset mining, the outputs of which are cryptocurrencies, which may be deemed a security. In the event that the digital assets held by the Company exceed 40% of its total assets, exclusive of cash, the Company may inadvertently become an investment company. An inadvertent investment company can avoid being classified as an investment company if it can rely on one of the exclusions under the Investment Company Act. One such exclusion, namely Rule 3a-2 under the Investment Company Act, allows an inadvertent investment company a grace period of one year from the earlier of (i) the date on which an issuer owns securities and/or cash having a value exceeding 50% of the issuer’s total assets on either a consolidated or unconsolidated basis and (ii) the date on which an issuer owns or proposes to acquire investment securities having a value exceeding 40% of the value of such issuer’s total assets (exclusive of government securities and cash items) on an unconsolidated basis. The Company is putting in place policies that it

Table of Contents

expects will work to keep the digital assets held by the Company at less than 40% of its total assets, liquidating its digital assets or seeking a no-action letter from the SEC if the Company is unable to maintain sufficient total assets or liquidate sufficient digital assets in a timely manner.

As Rule 3a-2 is available to a company no more than once every three years, and assuming no other exclusions are available to the Company, the Company would have to keep within the 40% limit for at least three years after it ceases being an inadvertent investment company. This may limit the Company’s ability to make certain investments or enter into joint ventures that could otherwise have a positive impact on the Company’s earnings. In any event, the Company does not intend to become an investment company engaged in the business of investing and trading securities.

Classification as an investment company under the Investment Company Act requires registration with the SEC. If an investment company fails to register, it would have to stop doing almost all business, and its contracts would become voidable. Registration is time consuming and restrictive and would require a restructuring of the Company’s operations, and the Company would be very constrained in the kind of business it could do as a registered investment company. Furthermore, the Company would become subject to substantial regulation concerning management, operations, transactions with affiliated persons and portfolio composition, and would need to file reports under the Investment Company Act regime. The cost of such compliance would result in the Company incurring substantial additional expenses, and the failure to register if required may adversely affect the Company’s business, financial condition and results of operations.

If federal or state legislatures or agencies initiate or release tax determinations that change the classification of bitcoins as property for tax purposes (in the context of when such bitcoins are held as an investment), such determination could have a negative tax consequence on the Company or its shareholders.

Current guidance from the Internal Revenue Service indicates that digital assets such as bitcoin should be treated and taxed as property and that transactions involving the payment of bitcoin for goods and services should be treated as barter transactions. While this treatment creates a potential tax reporting requirement for any circumstance where the ownership of a bitcoin passes from one person to another, usually by means of bitcoin transactions (including off-blockchain transactions), it would also apply capital gains treatment to those transactions which may adversely affect the Company’s business, financial condition and results of operations.

Risks Related to Ownership of Our Common Stock

The trading price of shares of our common stock has been subject to volatility.

The trading price of our common stock has been, and is likely to continue to be, volatile, and may be influenced by various factors including the risks, uncertainties and factors described in this Annual Report and our other filings with the SEC, as well as factors beyond our control or of which we may be unaware. If these risks happen and our business and results of operation suffer as a result, the market price of our securities may decline, which could have a material adverse effect on an investment in our securities.

Bitcoin is subject to price volatility resulting from financial instability, poor business practices, fraudulent activities of players in the market, and other factors outside of our control. Such factors may cause a decline in the price of bitcoin, which may affect the trading price of our shares of common stock. We have issued, and may continue to issue, new shares of our common stock, which has a dilutive effect.

We are and may continue to be subject to short selling strategies.

Short selling is the practice of selling securities that the seller does not own but rather has borrowed from a third party with the intention of buying identical securities back at a later date to return to the lender. The short seller hopes to profit from a decline in the value of the securities between the sale of the borrowed securities and the purchase of the replacement shares, as the short seller expects to pay less in that purchase than it received in the sale. As it is therefore in the short seller’s best interests for the price of the stock to decline, may short sellers publish, or arrange for the publication of, negative opinions regarding the relevant issuer and its business prospects to create negative market momentum and generate profits for themselves after selling a stock short. These short attacks have, in the past, led to selling of shares in the market.

We are, and may in the future may be, the subject of unfavorable allegations made by short sellers. For example, in August and October of this year, short sellers published reports that contained certain allegations against us that we believe to be misleading. Any such allegations may be followed by periods of instability in the market price of our shares

Table of Contents

of common stock and negative publicity. We may be constrained in the manner in which we can proceed against the relevant short seller by principles of freedom of speech, applicable federal or state law or issues of commercial confidentiality. In addition, any related inquiry or formal investigation from a governmental organization or other regulatory body, including any inquiry from the SEC or the U.S. Department of Justice, could result in a material diversion of our management’s time and could have a material adverse effect on our business and results of operations. Such a situation could be costly and time consuming and could distract our management from operating our business. SEC investigations are generally fact-finding inquiries and do not necessarily mean that the SEC has concluded that we have violated the federal securities laws or that the SEC has a negative view of the Company. Even if such allegations are ultimately proven to be groundless, allegations against us could adversely impact our business, and cause downward pressure and increased volatility in the price of our shares of common stock. In October 2024, we received an inquiry from the SEC relating to the allegations in the recent short seller reports relating to the sources of electricity used in our operations and the proportion of energy attributable to zero-carbon energy sources. We believe these allegations to be misleading and cooperated fully with the SEC. On January 31, 2025, the SEC informed us that the investigation was closed and that the SEC does not intend to recommend an enforcement action by the SEC against the Company.

We have financed our strategic growth through our at-the-market (ATM) offerings and issuances of our common stock.

Our ATM offerings allow us to raise capital as needed by tapping into the existing trading market for our shares by selling newly issued shares into the market depending on prevailing market prices. Our efforts to raise capital is for the purpose of executing on development plans and strategic growth opportunities as they arise; however, holders of our common stock may experience dilution as a result of our sales of newly issued shares of our common stock in such ATM offerings.

The issuance, conversion, or exercise of convertible notes and other convertible securities and warrants will dilute our stockholders' ownership.

We have issued, and may continue to issue, convertible securities and warrants to business counterparties and institutional investors. We have also issued convertible notes to certain institutional investors in private offerings. The exercise, conversion, or exchange of these instruments, including for other securities, will dilute existing stockholders’ ownership percentages. This dilution may negatively impact our ability to obtain additional capital. Holders of these securities may choose to exercise or convert them at times when we could otherwise secure equity capital on more favorable terms or when our common stock is trading above the exercise or conversion price.

Because we do not currently intend to pay any cash dividends on our common stock, our stockholders will not be able to receive a return on their shares unless they sell them.

We currently intend to retain any future earnings to finance the development and expansion of our business. We do not anticipate paying any cash dividends on our common stock in the near future. Unless we pay dividends, our stockholders will not be able to receive a return on their shares unless they sell them. There is no assurance that stockholders will be able to sell shares when desired.

ITEM 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the other Items included in this Annual Report and with the accompanying consolidated financial statements and notes thereto included elsewhere in this report. All figures presented below represent results from continuing operations, unless otherwise specified. Certain statements contained in this Management’s Discussion and Analysis of Financial Condition and Results of Operations may be deemed forward-looking statements. See “Forward-Looking Statements.”

Table of Contents

This MD&A generally discusses 2025 and 2024 items and year-to-year comparisons between 2025 and 2024. Discussions of 2023 items and year-to-year comparisons between 2024 and 2023 are not included, and can be found in "Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

Overview

We are a vertically integrated owner, developer, and operator of digital infrastructure assets in the United States, purpose-built to support HPC workloads, including AI, machine learning, and advanced cloud applications.

The Company has undergone a deliberate strategic transition toward HPC hosting as its primary business. While TeraWulf historically operated bitcoin mining facilities and leveraged flexible compute loads to support early infrastructure development, going forward the Company’s capital allocation, development activities, and operating focus are centered on HPC data center development, long-term hosting arrangements, and infrastructure supporting AI-driven compute workloads.

Our strategy is grounded in controlling infrastructure at utility scale and pairing compute-optimized facilities with reliable, long-duration power resources. By controlling land use through ownership or long-term ground leases, together with interconnection rights, electrical and cooling infrastructure, and, where appropriate, on-site generation, the Company delivers resilient, cost-efficient capacity to hyperscale and enterprise customers under multi-year hosting arrangements.

The Company’s platform is differentiated by long-term control of utility-scale infrastructure, deep in-house power and grid expertise, and a scalable development model supported by long-term, credit-enhanced customer contracts.

Strategy Execution and Capital Allocation

Management’s execution of the Company’s strategy is focused on converting advantaged infrastructure positions into long-dated, contracted HPC capacity. This execution model emphasizes vertical integration, long-duration customer contracts supported by credit enhancement, and phased development aligned with customer deployment schedules and power availability.

A core element of this approach is infrastructure control. By retaining control over land use, interconnection rights, electrical and cooling systems, and on-site generation where appropriate, the Company is able to manage development risk, optimize capital deployment, and maintain operational oversight throughout the lifecycle of its facilities. Management believes this approach reduces execution risk relative to third-party development models and supports infrastructure-style returns.

The Company’s contracting strategy prioritizes multi-year hosting arrangements with credit-supported counterparties. These arrangements provide long-dated revenue visibility, support project-level financing, and reduce cash flow volatility as the platform scales. Credit enhancement associated with certain customer contracts has been a key factor in accelerating development timelines and enabling third-party financing.

Each campus is designed for modular, multi-phase expansion. Initial phases deliver near-term contracted capacity, while subsequent phases are developed in line with customer demand and power availability. Management believes this phased approach allows the Company to scale efficiently while maintaining capital discipline.

Consistent with this strategy, the Company has deliberately shifted capital allocation away from new bitcoin mining investments and toward HPC data center development. While legacy mining operations continue to utilize existing infrastructure, management does not intend to deploy incremental growth capital to mining activities.

Strategic Transactions

Acquisition of Beowulf E&D

On May 21, 2025 (the “Acquisition Date”), the Company acquired 100% o f the membership interests in Beowulf Electricity & Data LLC, Beowulf E&D (NY) LLC and Beowulf E&D (MD) LLC (collectively, “Beowulf E&D”). Additional detail regarding the consideration paid and contingent consideration associated with the Beowulf E&D acquisition is included in Note 3 to the consolidated financial statements.

Table of Contents

The acquisition materially expanded the Company’s internal capabilities across power infrastructure development, site operations, engineering, and project execution. Approximately 94 employees transitioned to the Company as part of the transaction. Management believes this acquisition strengthened operational integration and execution capability as the Company scales its HPC platform.

Cayuga Site Ground Lease

On August 12, 2025, the Company entered into a long-term ground lease for approximately 183 acres in Lansing, New York. Upon completion of permitting and site development, the Cayuga Site has the potential for up to 400 MW of gross capacity, supporting approximately 320 MW of critical IT load. The Cayuga Site provides an additional anchor location with existing interconnection and supporting infrastructure and represents a key component of the Company’s forward development pipeline.

Abernathy Joint Venture

On October 27, 2025, the Company entered into an amended and restated limited liability company agreement governing the Abernathy Joint Venture. The Company holds a 50.1% equity interest in the joint venture. The Abernathy HPC Campus represents the extension of the Company’s commercial relationship with Fluidstack, supported by the same credit enhancement framework, to an additional site.

The Abernathy HPC Campus is designed for 168 MW of critical IT load, representing the full build-out of the site. The campus is 100% pre-leased to Fluidstack under a 25-year data center sublease with contractual rent escalators and options for term contraction. Lease obligations are supported by investment-grade credit enhancement provided by Google, materially strengthening the credit profile of the contracted revenues and facilitating third-party debt financing.

Management believes the Abernathy Joint Venture reflects the extension of the Company’s commercial relationship with Fluidstack, supported by continued credit enhancement from Google, to an additional site.

Operations Overview

The Company’s primary operating campus is the Lake Mariner Data Campus, located in Barker, New York on the site of a former coal-fired power plant that was retired and repurposed into a modern digital infrastructure campus. The site benefits from substantial existing transmission infrastructure and is designed for scalable expansion.

As of December 31, 2025 the Lake Mariner Data Campus operated 245 MW of legacy bitcoin mining capacity and had 18 critical IT MW of HPC capacity. The Company commenced HPC leasing operations at the Lake Mariner Data Campus in July 2025 and is executing a phased expansion to support additional contracted HPC deployments.

The campus is capable of scaling to approximately 500 MW of gross capacity in the near term, with potential expansion to approximately 750 MW subject to additional approvals from the NYISO. Power for the Lake Mariner Data Campus is sourced from the NYISO Zone A grid, with 90 MW allocated under a long-term arrangement with the New York Power Authority.

The Company operates the Lake Mariner Data Campus through La Lupa and Akela. Together, the Company’s contracted HPC platform represents 522 MW of critical IT load, including the Company’s 50.1% attributable share of the Abernathy HPC Campus. As of December 31, 2025, the Company had energized 18 critical IT MW of HPC capacity and remains on track to deliver additional contracted capacity in phases aligned with customer deployment schedules.

Regional Diversification and Platform Resilience

The development of the Abernathy HPC Campus through the Abernathy Joint Venture provides the Company with meaningful regional diversification. By expanding its HPC platform beyond New York into the Southwest Power Pool region, the Company reduces concentration risk related to power markets, regulatory frameworks, weather events, construction timelines, and operational disruptions.

Geographic diversification also helps mitigate the potential impact of localized physical security incidents, natural disasters, and certain cyber events by distributing infrastructure across multiple regions and operating environments. Management believes this diversification enhances overall platform resilience, supports customer deployment flexibility, and strengthens the Company’s ability to maintain continuity of operations across its portfolio.

Power Strategy

The Company’s power strategy emphasizes reliability, efficiency, and responsible integration with regional electric grids. The Company’s development and operations team brings deep experience in power generation, transmission, interconnection, and large-scale energy infrastructure, which informs site selection, facility design, and operational execution.

This power and infrastructure expertise enables the Company to evaluate complex, power-intensive sites efficiently and provides meaningful differentiation relative to data center developers without comparable in-house energy capabilities. The Company expects certain sites to include on-site generation, battery storage and other dispatchable resources to enhance reliability for mission-critical compute and to support grid operations where appropriate.

Liquidity and Capital Resources

The Company’s primary sources of liquidity include cash on hand, cash generated from operations, sale proceeds from bitcoin, equity issuances, debt financing, and project-level financing arrangements. Capital requirements are driven primarily by HPC data center development, construction activities, and associated infrastructure investments.

Management expects future capital deployment to be focused on contracted HPC projects and disciplined expansion of the Company’s development pipeline. The Company continues to evaluate financing alternatives to support growth while managing balance sheet risk.

Outlook

The Company expects future results to be increasingly influenced by the development and operation of its HPC data center platform. As contracted HPC capacity is delivered and energized under existing hosting arrangements, management expects the Company’s revenue mix to continue shifting toward HPC leasing and away from legacy bitcoin mining operations.

Future performance will depend on the timing of construction, commissioning, customer deployment schedules, access to power and interconnection, and the availability of project-level financing. Management expects capital deployment in future periods to be focused primarily on contracted HPC projects and disciplined expansion of the Company’s development pipeline.

Number of miners

Bitmain S19 XP

Bitmain S19j XP

Bitmain S19k Pro

Bitmain S21

Bitmain S21 Pro

As of December 31, 2025, our fleet of miners ranged in age from 0.7 years to 3.6 years and have an average age of approximately 1.2 years. We do not have scheduled downtime for our miners and while we periodically perform unscheduled maintenance on our miners, such downtime has not been significant historically. When performing unscheduled maintenance, depending on the length of estimated repair time, we may replace a miner with a substitute miner to limit overall downtime. As of December 31, 2025, our fleet of miners at the LMD Bitcoin Mining Facilities had a range of energy efficiency from 15 to 23 joules per terahash (“j/th”) and has an average energy efficiency of 17.2 j/th.

Bitcoin Mining - Share of Global Hashrate

Several factors influence our ability to mine bitcoin profitably, including bitcoin’s USD value, mining difficulty, global hashrate, power costs, fleet energy efficiency, and overall data center efficiency. Among these, energy efficiency is a critical driver of profitability, as power costs represent the most significant direct expense in bitcoin mining. We believe we operate a highly efficient mining fleet, optimized to maximize output while minimizing energy consumption. To assess operational performance and effectiveness, the Company tracks key metrics, which we believe are also valuable to investors for evaluating our progress and benchmarking against industry peers.

The table below presents our miner efficiency and computing power as compared to the global computing power as of December 31, 2025 and 2024:

December 31, 2025

(1) Results as of December 31, 2024 reflect hashrate of mining operations at the LMD Bitcoin Mining Facilities and TeraWulf’s net share of hashrate produced at the Nautilus Cryptomine Facility.

(2) Total global hashrate obtained from YCHARTS (https://ycharts.com/indicators/bitcoin_network_hash_rate)

(3) Joules of energy required to produce each terahash of processing power

(4) While nameplate at the LMD Bitcoin Mining Facilities was 10.9 EH/s and 9.7 EH/s as of December 31, 2025 and 2024, respectively, actual operational hashrate depends on a variety of factors, including (but not limited to) performance tuning to increase efficiency and maximize margin, scheduled outages (scopes to improve reliability or performance), unscheduled outages, curtailment due to participation in various cash generating demand response programs, derate of ASICS due to adverse weather and ASIC maintenance and repair.

As of December 31, 2025, our operating hashrate represented approximately 0.9% of the total global hashrate, aligning with our share of global blockchain rewards. As of that date, this translated to approximately 4 bitcoin mined per day. To maintain profitability, we focus on optimizing operational efficiency and cost management, ensuring that our mining rewards consistently cover direct operating expenses.

(1) “Cost to mine one bitcoin” is a cash cost metric and does not include depreciation. Although the Company recognizes depreciation with respect to its mining assets, it does not consider depreciation in determining whether it is economical to operate its mining equipment. As a result, the Company does not consider the sunk costs or depreciation of past capital investments in its historical or forecasted breakeven analysis. If depreciation of our miner fleet were factored into the above cost of mining analysis, it would add $41,930 and $22,086 per bitcoin mined for the years ended December 31, 2025 and 2024, respectively, bringing the total “cost to mine one bitcoin” to $95,611 and $47,354 for the years ended December 31, 2025 and 2024, respectively.

(2) Computed as the weighted-average opening price of bitcoin on each respective day the mined bitcoin is earned. Excludes bitcoin earned from profit sharing associated with a bitcoin miner hosting agreement that expired in February 2024 at the LMD Bitcoin Mining Facilities.

(3) Excludes bitcoin earned from profit sharing associated with a bitcoin miner hosting agreement that expired in February 2024 at the LMD Bitcoin Mining Facilities of 0 and 6 bitcoin for the years ended December 31, 2025 and 2024, respectively, and includes TeraWulf’s net share of bitcoin mined at the Nautilus Cryptomine Facility, based on the hashrate share attributed to the Company.

(4) Excludes energy expenses associated with a bitcoin miner hosting agreement that expired in February 2024 at the LMD Bitcoin Mining Facilities and includes TeraWulf’s net share of energy expense at the Nautilus Cryptomine Facility, based on aggregate nameplate power consumption of deployed miners attributed to TeraWulf’s contribution to Nautilus.

Power costs are the most significant expense in our bitcoin mining operations, accounting for 52.9% and 40.1% of the total value of bitcoin mined for the years ended December 31, 2025 and 2024, respectively. The increase in power costs as a percentage of bitcoin mined in 2025 compared to 2024 was primarily driven by an approximate 30% increase in the realized cost per kWh and a near doubling of network difficulty and the bitcoin halving event in April 2024, which reduced block rewards. These impacts were partially offset by growth in our average operating hashrate for a portion of 2025 and an increase in the average market value of each bitcoin mined.

Energy prices are highly volatile, influenced by global events that can drive nationwide fluctuations in power costs. At the LMD Bitcoin Mining Facilities, power costs are subject to variable market rates, which can change hourly based on wholesale electricity pricing. While this introduces some unpredictability, it also provides us with the flexibility to actively manage our energy consumption, optimizing for profitability and efficiency. Energy prices are also highly sensitive to weather conditions, such as winter storms and polar vortices, which can increase regional power demand and drive up costs. During such events, we may curtail operations to avoid consuming power at peak rates, or we may be curtailed under demand response programs in which we participate. For the years ended December 31, 2025 and 2024, the average aggregate realized power prices at the LMD Bitcoin Mining Facilities and Nautilus Cryptomine Facility were $0.060 and $0.043 per kilowatt hour, respectively.

Table of Contents

Our management team continuously monitors market conditions to determine when and for how long to curtail operations. If curtailment is not mandated under demand response programs, we make real-time decisions to curtail mining whenever power prices exceed the value of the fixed bitcoin reward. As a result, curtailment increases when bitcoin’s value declines or energy prices rise, and decreases when bitcoin’s value appreciates or energy costs fall. These decisions are actively managed on an hour-by-hour basis to optimize profitability.

During the years ended December 31, 2025 and 2024, we curtailed operations at the LMD Bitcoin Mining Facilities in response to weather events, energy price spikes, and participation in demand response programs. The Company records expected payments to be received for demand response programs as a reduction in cost of revenue, which amounted to $17.7 million and $8.6 million for the years ended December 31, 2025 and 2024, respectively.

The Company has purchased all miners with cash, without relying on limited recourse equipment financing for miner acquisitions. To support operations, invest in our previously owned Nautilus joint venture, and purchase miners and other fixed assets, we have raised capital through both equity issuances and corporate-level debt. Costs related to these capital raises are not included in this analysis.

Miner acquisition costs, or capital expenditures, are not factored into the cost of mining analysis, as they do not impact the marginal cost of producing one bitcoin. Instead, these costs are recorded as property, plant, and equipment in the consolidated balance sheets. Depreciation of property, plant, and equipment is calculated using the straight-line method, with estimated useful lives of four years for miners and five years for computer equipment.

During the year ended December 31, 2025, the Company recorded accelerated depreciation expense of $19.6 million related to a certain miner building and related miners of which the Company shortened their useful lives based on expected shutdown of operations for purposes of supporting the HPC operations. During the year ended December 31, 2024, the Company recorded accelerated depreciation expense of $5.1 million related to certain miners of which the Company shortened their estimated useful lives based on replacement by April 30, 2024. While our standard depreciation period for miners is four years, historically low power costs may allow for a longer actual useful life in certain cases. However, if depreciation were included in the cost of mining analysis, it would add $41,930 and $22,086 per bitcoin mined for the years ended December 31, 2025 and 2024, respectively.

Estimating asset useful lives requires management judgment, particularly given the rapid evolution of next-generation mining rigs in industrial-scale bitcoin mining. Depreciation schedules may be adjusted if events, regulatory changes, or shifts in operating conditions indicate a need for revision. Management continuously evaluates factors such as future energy market conditions, operating costs, maintenance practices, and capital investment needs to ensure depreciation assumptions remain reasonable. When an asset’s estimated useful life is adjusted—either shortened or extended—depreciation provisions are updated accordingly, which could have a material impact on future financial results.

Recent Developments

On February 2, 2026, the Company entered into an Agreement of Purchase and Sale for a former industrial site in Hawesville, Kentucky (“Hawesville”). The Company exercised an exclusivity option to purchase Hawesville, which includes more than 250 buildable acres with immediate access to power infrastructure, including multiple high-voltage transmission lines, an on-site energized substation, and a direct connection to the regional transmission network. The Hawesville seller was granted a 6.8% minority equity interest in TeraWulf’s Hawesville development entity, which is intended to develop and own a high-performance computing/artificial intelligence data center on the property. The Hawesville seller has the right to request the redemption of its minority interest starting on the first anniversary of the data center’s commencement of operations (the “Operations Anniversary Date”). The Hawesville seller will not participate in the development, financing, construction, management or operation of the data center and will not have any obligations to contribute capital, unless its minority interest is not redeemed in full within 30 days after the Operations Anniversary Date. The Hawesville acquisition does not require any third-party consents or regulatory approvals and closed effective February 2, 2026.

Additionally, on February 2, 2026, the Company issued a press release announcing the entry into an Equity and Asset Purchase Agreement (the “Morgantown Purchase Agreement”) for the Morgantown generating station in Charles County, Maryland, The Morgantown Purchase Agreement was signed in late 2025 and contemplates the acquisition of the Morgantown generating station, a grid-connected power generation facility with approximately 210 MW of current operational capacity, including electrical infrastructure, associated real property, contracts and other assets (“Morgantown”). The closing of the Morgantown acquisition is subject to certain third-party consents and customary regulatory approvals, including from the Federal Energy Regulatory Commission. The Company expects to close on the Morgantown acquisition in the second quarter of 2026, subject to receiving these consents and approvals.

Results of Operations - Comparative Results for the Years Ended December 31, 2025 and 2024

The Company generates revenue in the form of bitcoin by providing hash computation services to a mining pool operator to mine bitcoin and validate transactions on the global bitcoin network using miners owned by the Company. The earned bitcoin are routinely sold for U.S. dollars. The Company also previously earned revenue by providing bitcoin miner hosting services to third parties.

In July 2025, the Company commenced its HPC leasing operations. HPC lease revenue is generated by leasing datacenter space and providing related services to our HPC customers. These leasing agreements include lease components, nonlease components (such as power delivery, physical security, maintenance), as well as non-component elements such as taxes. Under these leases, customers pay fixed payments (based on electric capacity) and variable payments on a recurring basis. HPC power costs are passed through to the customer without markup and are included on a gross basis in HPC lease revenue.

The Company’s business strategy centers on maximizing revenue and profitability of our bitcoin mining fleet while expanding our datacenter infrastructure to support HPC leasing activities. We plan to operate infrastructure necessary for profitable bitcoin mining while pursuing high-value HPC leasing opportunities that leverage our power utilization and digital infrastructure. We are confident our expertise in power infrastructure and digital asset mining can be favorably applied to the design, development, and operation of large-scale datacenters. These datacenters are optimized for high-value applications such as cloud computing, machine learning, and artificial intelligence. We are actively seeking opportunities to expand into these areas using our knowledge, expertise, and existing infrastructure wherever favorable market opportunities arise.

Total revenue

Total revenue for the years ended December 31, 2025 and 2024 was $168.5 million and $140.1 million, respectively, representing an increase of $28.6 million.

Digital asset revenue for the years ended December 31, 2025 and 2024 was $151.6 million and $140.1 million, respectively, an increase of $11.5 million. The increase was primarily attributed to an increase in the average price of bitcoin during the year ended December 31, 2025 of $101,658 as compared to $65,824 during 2024. This increase was partially offset by a decrease in the total bitcoin mined to 1,496 bitcoin during the year ended December 31, 2025 as compared to 2,177 bitcoin mined during the same period in the prior year. Although the Company expanded its mining infrastructure capacity at the LMD Bitcoin Mining Facilities to approximately 245 MW as of December 31, 2025 as compared to 195 MW as of December 31, 2024, total bitcoin mined decreased due to the halving in April 2024 and the increase in network hashrate.

During the years ended December 31, 2025 and 2024, revenue from bitcoin miner hosting was $0 and $0.8 million, respectively, a decrease due to the expiration of the Company’s bitcoin miner hosting contract with a customer in February 2024.

HPC lease revenue for the year ended December 31, 2025 was $16.9 million. In July 2025, the Company commenced its HPC leasing operations and as of December 31, 2025 had energized 18 critical IT MW of HPC leasing capacity at the Lake Mariner Data Campus.

Costs and Expenses

The following table presents cost of revenue (exclusive of deprecation) (in thousands):

Year Ended December 31,

Cost of revenue (exclusive of depreciation)

Cost of revenue (exclusive of depreciation) for the years ended December 31, 2025 and 2024 was $82.7 million and $62.6 million, respectively, an increase of approximately $20.1 million. Cost of revenues is primarily comprised of power expense which increased for the year ended December 31, 2025 as compared to the year ended December 31, 2024, resulting from higher realized power prices during the 2025 period partially offset by higher proceeds from participation in demand response programs.

Proceeds from participation in demand response programs are recorded as a reduction in cost of revenue in the period in which the underlying program occurs. These proceeds totaled $17.7 million and $8.6 million for the years ended December 31, 2025 and 2024, respectively. The Company is actively expanding its enrollment in such available programs in New York State.

The following table presents operating expenses (in thousands):

Year Ended December 31,

Operating expenses

Operating expenses - related party

Operating expenses (including related party expenses) for the years ended December 31, 2025 and 2024 were approximately $19.7 million and $7.6 million, respectively, a net increase of $12.1 million. Operating expenses increased primarily due to higher miner repairs of $2.9 million and increased site labor of $2.6 million driven by the expansion of operations at the Lake Mariner Data Campus. Operating expense - related party increased primarily due higher rent subsequent to the New Ground Lease in October 2024 of $4.4 million, partially offset by $1.0 million of site labor at the Lake Mariner Data Campus which was previously reported in operating expenses-related party and since the acquisition of Beowulf E&D in May 2025 is included in operating expenses.

The following table presents selling, general and administrative expenses (in thousands):

Year Ended December 31,

Selling, general and administrative expenses

Selling, general and administrative expenses - related party

Selling, general and administrative expenses (including related party expenses) for the years ended December 31, 2025 and 2024 were $147.8 million and $70.6 million, respectively, a net increase of $77.2 million. Selling, general and administrative expenses increased primarily due to increased expense during the year ended December 31, 2025 as compared to the same period in the prior year of (i) employee compensation and benefits of $47.7 million, (ii) stock-based compensation of $20.0 million, (iii) travel expenses of $2.4 million, (iv) legal and other professional fees of $5.1 million, (v) and Beowulf E&D acquisition-related costs of $1.5 million.

Selling, general and administrative expenses – related party decreased a net $4.5 million primarily due to a full year of fees incurred under the Services Agreement with Beowulf E&D for the year ended December 31, 2024 as compared

to 2025 in which fees were only incurred up to the termination of the Services Agreement in May 2025 upon the acquisition of Beowulf E&D.

Depreciation for the years ended December 31, 2025 and 2024 was $88.6 million and $59.8 million, respectively. The increase was primarily due to mining and HPC infrastructure constructed and placed in service between December 31, 2024 and December 31, 2025 at the Lake Mariner Data Campus. Additionally, during the year ended December 31, 2025, the Company recorded accelerated depreciation expense of $19.6 million related to a certain miner building and related miners of which the Company shortened their useful life based on expected shutdown of operations for purposes of supporting the HPC operations. The increase was partially offset by (i) decrease in depreciation on certain electrical equipment and leasehold improvements related to a change in accounting estimate of useful lives in connection with the New Ground Lease in October 2024 and (ii) accelerated depreciation expense of $5.1 million during the year ended December 31, 2024 related to certain miners of which the Company shortened their estimated useful lives based on expected replacement by April 2024.

Loss (gain) on fair value of digital assets, net for the years ended December 31, 2025 and 2024 was $0.6 million and $(2.2) million due to the volatility in the price of bitcoin during the year ended December 31, 2025 as compared to a steady increase during the year ended December 31, 2024.

Change in fair value of contingent consideration was $10.4 million during the year ended December 31, 2025 related to fair value remeasurement of contingent consideration liabilities related to the acquisition of Beowulf E&D based on milestones achieved during the year ended December 31, 2025.

During the year ended December 31, 2025, the Company sold or otherwise disposed of 17,228 miners and received proceeds of $11.6 million resulting in a net loss on disposal of property, plant and equipment of $4.9 million in the consolidated statement of operations. During the year ended December 31, 2024, the Company sold or otherwise disposed of 62,970 miners and received proceeds of $23.3 million resulting in a net loss on disposal of property, plant and equipment of $17.8 million in the consolidated statement of operations.

Interest expense for the years ended December 31, 2025 and 2024 was $80.2 million and $19.8 million, respectively, an increase of $60.4 million. The increase is primarily attributed to stated interest expense of $58.0 million and amortization of debt issuance costs of $22.2 million related to the 2030 Secured Notes, 2031 Convertible Notes and 2032 Convertible Notes which were issued during the year ended December 31, 2025 as well as the 2030 Convertible Notes issued in October 2024. The $19.8 million of interest expense recognized in the year ended December 31, 2024, primarily related to the borrowings under the Loan, Guaranty and Security Agreement with Wilmington Trust (the “Term Loans”), which were fully repaid in July 2024 ahead of maturity.

Change in fair value of warrant and derivative liabilities during the year ended December 31, 2025 was $429.8 million related to the Google Warrants and the conversion feature of the 2031 Convertible Notes which was originally accounted for separately as a derivative liability.

Loss on extinguishment of debt during the year ended December 31, 2024 was $6.3 million related to voluntary prepayment of the Term Loans in February and July 2024, reflecting $1.3 million of prepayment fees and the derecognition of unamortized debt discount of $5.0 million associated with the principal repaid. No loss on extinguishment of debt was recorded during the year ended December 31, 2025.

Income tax provision was $76,000 and $0 for the years ended December 31, 2025 and 2024, respectively. Based upon the level of historical U.S. losses and future projections over the period in which the net deferred tax assets are deductible, at this time, management believes it is more likely than not that the Company will not realize the benefits of the remaining deductible temporary differences, and as a result the Company has recorded a full valuation allowance against its net deferred tax assets as of December 31, 2025 and 2024, except for a $76,000 deferred tax liability as of December 31, 2025 arising from indefinite-lived assets (e.g., tax-deductible goodwill related to the acquisition of Beowulf E&D) that cannot be used as a source of taxable income to support the realization of deferred tax assets when a full valuation allowance is in place.

Equity in net loss of investee, net of tax for the year ended December 31, 2025 was $4.1 million which represents TeraWulf’s proportional share of net loss of the Abernathy Joint Venture which was formed in October 2025 and has not yet commenced operations. The $3.4 million equity in net income of investee, net of tax for the year ended December 31, 2024 represents TeraWulf’s proportional share of the net income of Nautilus prior to the Company’s divestiture of its entire 25% equity interest in Nautilus in October 2024.

Additionally the Company recorded a gain on sale of equity interest in investee of $22.6 million in the consolidated statement of operations for the year ended December 31, 2024 as a result of the sale of its interest in Nautilus in October 2024.

Non-GAAP Measure

To provide investors with additional information in connection with our results as determined in accordance with generally accepted accounting principals in the United States (“U.S. GAAP”), we disclose Adjusted EBITDA as a non-GAAP measure. This measure is not a financial measure calculated in accordance with U.S. GAAP, and it should not be considered as a substitute for net loss, operating loss, or any other measure calculated in accordance with U.S. GAAP, and may not be comparable to similarly titled measures reported by other companies.

We define Adjusted EBITDA as net loss adjusted for (i) impacts of interest, taxes, depreciation and amortization; (ii) stock-based compensation expense, amortization of right-of-use asset and related party expense to be settled with respect to common stock, all of which are non-cash items that the Company believes are not reflective of its general business performance, and for which the accounting requires management judgment, and the resulting expenses could vary significantly in comparison to other companies; (iii) one-time, non-recurring transaction-based compensation expense related to the 2030 Convertible Notes (iv) equity in net (loss) income of investee, net of tax, related to the Abernathy Joint Venture and Nautilus and the gain on sale of interest in Nautilus; (v) other income which is related to interest income or income for which management believes is not reflective of the Company’s ongoing operating activities; (vi) change in fair value of contingent consideration, change in fair value of warrant and derivative liabilities, loss on extinguishment of debt and net losses on disposals of property, plant and equipment, net, which are not reflective of the Company’s general business performance; and (vii) acquisition-related transaction costs which management believes are not reflective of the Company’s ongoing operating activities. The Company’s Adjusted EBITDA also includes the impact of distributions from investee received in bitcoin related to a return on the Nautilus investment, which management believes, in conjunction with excluding the impact of equity in net (loss) income of investee, net of tax, is reflective of assets available for the Company’s use in its ongoing operations as a result of its investment in Nautilus.

Management believes that providing this non-GAAP financial measure allows for meaningful comparisons between the Company's core business operating results and those of other companies, and provides the Company with an important tool for financial and operational decision making and for evaluating its own core business operating results over different periods of time. In addition to management's internal use of non-GAAP Adjusted EBITDA, management believes that Adjusted EBITDA is also useful to investors and analysts in comparing the Company’s performance across reporting periods on a consistent basis. Management believes the foregoing to be the case even though some of the excluded items involve cash outlays and some of them recur on a regular basis (although management does not believe any of such items are normal operating expenses necessary to generate the Company’s revenues). For example, the Company expects that share-based compensation expense, which is excluded from Adjusted EBITDA, 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, directors and consultants.

The Company’s Adjusted EBITDA measure may not be directly comparable to similar measures provided by other companies in the Company’s industry, as other companies in the Company’s industry may calculate non-GAAP financial results differently. The Company's Adjusted EBITDA is not a measurement of financial performance under U.S. GAAP and should not be considered as an alternative to net loss or any other measure of performance derived in accordance with U.S. GAAP. Although management utilizes internally and presents Adjusted EBITDA, the Company only utilizes that measure supplementally and does not consider it to be a substitute for, or superior to, the information provided by U.S. GAAP financial results. Accordingly, Adjusted EBITDA is not meant to be considered in isolation of, and should be read in conjunction with, the information contained in the Company’s consolidated financial statements, which have been prepared in accordance with U.S. GAAP.

Liquidity and Capital Resources

As of December 31, 2025, the Company had balances of cash and cash equivalents of $3,266.4 million, working capital of $1,742.4 million, total stockholders’ equity of $140.4 million and an accumulated deficit of $993.7 million. The Company incurred a net loss of $661.4 million for the year ended December 31, 2025. The Company began mining bitcoin in March 2022 and had 9.3 EH/s of operating capacity as of December 31, 2025. In 2025, the Company commenced its HPC operations. To date, the Company has relied primarily on proceeds from the sale of bitcoin, both self-mined and distributed from the joint venture which owned the Nautilus Cryptomine Facility, and its issuances of debt and equity to fund its principal operations.

The principal uses of cash are for the operation and buildout of data center facilities, debt service, and general corporate activities and, to a lesser extent in 2024, investments in the Nautilus joint venture related to mining facility buildout and activities.

Operating activities

Cash used in operating activities for continuing operations was $123.2 million and $24.4 million for the years ended December 31, 2025 and 2024, respectively, reflecting an increase of $98.8 million. During the year ended December 31, 2025, the Company began HPC operations which resulted in segment profit of $7.1 million. While the Company continued to profitably mine bitcoin during the year ended December 31, 2025, the Company reported $10.9 million lower digital asset segment profit as compared to the prior year primarily due to the halving in April 2024 and the increase in network hashrate as compared to prior year. The Company also received inflows from (i) prepaid rent from customers net of commissions paid of $51.6 million and (ii) interest income proceeds net of interest paid of $28.1 million, partially offset by outflows resulting from (i) increased selling, general and administrative expenses (including related party, but exclusive of noncash stock based compensation) of $57.2 million and (ii) cash paid for unearned HPC tenant fit-out of $11.0 million, during the year ended December 31, 2025 as compared to the prior year.

Additionally, prior to the repayment of the Term Loans in July 2024, the Company converted its bitcoin holdings nearly immediately to cash and the related proceeds from sales of digital assets of $97.6 million were included within cash flows from operating activities in the consolidated statements of cash flows.

Investing activities

Cash used in investing activities was $1,368.9 million and $91.2 million for the years ended December 31, 2025 and 2024, respectively, reflecting an increase of $1,277.8 million. The increase is primarily attributed to (i) an increase in purchases of plant and equipment of $792.2 million related to infrastructure intended to support expansion into HPC leasing operations, (ii) lower proceeds from sales of property, plant and equipment of $11.7 million, (iii) investments in joint venture of $450.0 million, and (iv) $21.7 million for the acquisition of Beowulf E&D. The increase in cash used in investing activities were partially offset by increases in cash provided by investing activities related to proceeds from sales of digital assets of $84.0 million during the year ended December 31, 2025 as compared to the prior year, as the Company began classifying proceeds from sales of digital assets in investing activities starting July 2024. Additionally, during the year ended December 31, 2024, the Company received proceeds from sale of equity interest in investee of $86.1 million related to the sale of Nautilus.

Financing activities

Cash provided by financing activities was $4,940.8 million and $335.2 million for the years ended December 31, 2025 and 2024, respectively. reflecting an increase of $4,605.6 million. The increase is primarily attributed to the proceeds from issuance of long-term debt and convertible notes, net of issuance costs paid, of $5,106.7 million for the year ended December 31, 2025 as compared to $487.1 million in the prior year. Additionally, the Company purchased treasury stock of $33.3 million during the year ended December 31, 2025 as compared to $118.2 million in the prior year. These increases were partially offset by increases in cash used to purchase capped calls of $40.6 million, payments related to finance leases of $8.2 million, and payments for tax withholdings related to net share settlements of stock-based compensation awards of $4.8 million. Additionally, during the year ended December 31, 2024, the Company made principal payments of long-term debt of $139.4 million as compared to $0 during the year ended December 31, 2025.

Financial Condition

The Company incurred a net loss of $661.4 million and reported cash used in operating activities of $123.2 million for the year ended December 31, 2025. As of December 31, 2025, the Company had balances of cash and cash equivalents of $3,266.4 million, working capital of $1,742.4 million, total stockholders’ equity of $140.4 million and an accumulated deficit of $993.7 million. For the year ended December 31, 2025, the Company leveraged its strategic transition toward HPC leasing and execution of long-term lease agreements with Fluidstack, which benefit from substantial credit support provided by Google, to enable efficient financing and funding of the phased development of the La Lupa and Akela facilities. Prior to these developments, the Company historically relied primarily on proceeds from sales of digital assets, both self-mined and distributed from the joint venture which owned the Nautilus Cryptomine Facility, and its issuances of debt and equity to fund its principal operations.

Critical Accounting Estimates

The above discussion and analysis of the Company’s financial condition and results of operations are based upon its consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of the Company’s consolidated financial statements requires management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Future events and their effects cannot

be determined with absolute certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results inevitably will differ from those estimates, and such differences may be material to the financial statements.

See Note 2 of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report for a summary of the Company’s significant accounting policies.

HPC Leasing

In December 2024, the Company entered into long-term datacenter lease agreements (the “HPC Leases”) with a customer for specified datacenter infrastructure at the Lake Mariner Data Campus to support the customer’s HPC operations. In accordance with ASC 842, Leases, the Company determined at contract inception that these agreements contained a lease, comprising lease components related to the right to use datacenter space and nonlease components for power delivery, physical security, and maintenance services. Certain of the HPC Leases commenced in 2025 and the remainder of the HPC Leases are expected to commence in 2026.

The Company has elected the practical expedient available under ASC 842, Leases, to combine the nonlease revenue components that have the same pattern of transfer as the related operating lease components into a single combined component. The single combined component is accounted for under ASC 842 as an operating lease if the lease components are the predominant components and is accounted for under ASC 606 if the nonlease components are the predominant components. The lease components are the predominant components in the Company’s long term lease agreements and the single combined component in these arrangements are accounted for under the operating lease guidance of ASC 842. Recognition of HPC lease revenue begins when the Company determines the asset has been made available for the customer’s use.

The Company has concluded that it is probable that substantially all of the payments will be collected over the term of the arrangements and recognize the total combined fixed payments under the agreements on a straight-line basis over the noncancellable term. The Company recognizes the difference between straight-line revenue recognized during the period and the lease payments due pursuant to the underlying arrangement as deferred rent liability or accrued rent receivable in the consolidated balance sheets. Certain arrangements include options to extend the term. These extension options are not reasonably certain to be exercised and are excluded from the lease term and calculation of lease payments at lease commencement.

Payments for physical security and other routine maintenance services are included in the fixed lease payments. The lease agreements provide for variable payments for power delivery. Power delivery services represent a stand-ready obligation to make power available to the customer over the coterminous lease term and have the same pattern of transfer as the related operating lease components. Customers are charged monthly for actual power costs incurred at current utility rates. These payments from customers for power delivery are recognized as variable lease payments in accordance with the practical expedient elected. Variable lease payments are presented on a gross basis and are included in HPC lease revenue in the consolidated statements of operations.

The lease agreements also provide for variable payments for certain fit-out services as requested by the customer and the Company recognizes revenues as performance obligations are satisfied. In the course of providing its services, the Company routinely subcontracts for services and incurs other direct costs on behalf of its customers. These costs are passed through to the customers, generally with a mark-up, and, in accordance with U.S. GAAP, are included in the Company’s HPC lease revenue.

Digital assets

Digital assets is comprised of bitcoin earned as noncash consideration in exchange for providing hash computation services to a mining pool as well as consideration for bitcoin miner hosting services. From time to time, the Company also receives bitcoin as distributions-in-kind from its joint venture.

Bitcoin are accounted for as intangible assets with indefinite useful life and is included in current assets in the consolidated balance sheets due to the Company’s ability to sell it in a highly liquid marketplace and because the Company reasonably expects to liquidate its bitcoin to support operations within the next twelve months. The Company elected to early adopt ASU 2023-08 effective January 1, 2024, which requires digital assets to be valued at fair value each reporting period in accordance with ASC 820 with changes in fair value recorded in net income. Gains and losses from the remeasurement of digital assets are included within gain on fair value of digital assets, net in the consolidated statements of operations. The Company sells bitcoin and gains and losses from such transactions, measured as the difference between the

cash proceeds and the cost basis of bitcoin as determined on a first-in-first-out basis, are also included within gain on fair value of digital assets, net in the consolidated statements of operations.

Prior to the adoption of ASU 2023-08, bitcoin was assessed for impairment annually, or more frequently if events or changes in circumstances indicate it is more likely than not that the asset is impaired. The Company elected to bypass the optional qualitative impairment assessment and to track its bitcoin activity daily for impairment assessment purposes. The Company performed an analysis each day to identify whether events or changes in circumstances, principally decreases in the quoted price of bitcoin on the active trading platform, indicated that it was more likely than not that its bitcoin were impaired. For impairment testing purposes, the lowest intraday trading price of bitcoin was identified at the single bitcoin level (one bitcoin). The excess, if any, of the carrying amount of bitcoin and the lowest daily trading price of bitcoin represented a recognized impairment loss. To the extent an impairment loss was recognized, the loss established the new cost basis of the asset. Subsequent reversal of previously recorded impairment losses was prohibited.

Bitcoin earned through mining activities is recorded as an adjustment in the consolidated statements of cash flows, reconciling net loss to cash flows from operating activities. Bitcoin received as distributions-in-kind from equity investees is disclosed in supplemental noncash investing activities.

Prior to the repayment of the Term Loans in July 2024 (see Note 10), bitcoin sales proceeds were included in cash flows from operating activities, as bitcoin was converted into cash immediately during that period. Following repayment of the Term Loans, bitcoin sales proceeds are now classified under cash flows from investing activities, as the Company no longer converts bitcoin into cash immediately upon mining.

Long-lived Assets

Property, plant and equipment are recorded at cost, net of accumulated depreciation. Judgment is necessary in estimating the Company’s various assets’ useful lives. This includes evaluating the Company’s own usage experience with its currently owned assets, the quality of materials used in construction-related projects and, for its miners, the rate of technological advancement and market-related factors such as the price of bitcoin and the bitcoin network hashrate, which impact the value of the miners. Depreciation is computed using the straight-line method over the estimated useful lives of the assets (generally 5 years for computer equipment and 4 years for miners). Leasehold improvements and electrical equipment are depreciated over the shorter of their estimated useful lives or the lease term. Changes in depreciation and amortization, generally accelerated depreciation, are determined and recorded when estimates of the remaining useful lives or residual values of long-term assets change.

The Company reviews its long-lived assets, including property, plant and equipment, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset, or asset group, may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted cash flows expected to be generated by the asset. Significant judgment is used when estimating future cash flows, particularly the price of bitcoin and the network hashrate. Any impairment loss recorded is measured as the amount by which the carrying value of the assets exceeds the fair value of the assets. Should our estimates of useful lives, undiscounted cash flows, or asset fair values change, additional and potentially material impairments may be required, which could have a material impact on our reported financial results.

Stock-based compensation

The Company measures stock-based compensation cost related to share-based payment awards at the grant date of the award, based on the estimated fair value of the award. For restricted stock units (“RSUs”) with time-based vesting, the fair value is determined by the Company’s common stock price on the date of the grant. For RSUs with vesting based on market conditions (“PSUs”), the effect of the market condition is considered in the determination of fair value on the grant date using a Monte Carlo simulation model. Stock-based compensation expense for PSUs is recorded over the derived service period unless the market condition is satisfied in advance of the derived service period, in which case a cumulative catch-up is recognized as of the date of achievement. Stock-based compensation for PSUs is recorded regardless of whether the market conditions are met unless the service conditions are not met. The Company accounts for forfeitures as they occur. The Company uses significant judgment in determining the likelihood of meeting milestones and market conditions. Inputs into valuation models such as Monte Carlo simulations include both the Company’s and guideline public company historical and expected annual volatility and, depending on the inputs selected, the Company could calculate significantly different estimated grant date fair values, materially impacting the valuation of our stock-based awards and the stock-based compensation expense we recognize in future periods.

Income Taxes

The Company accounts for income taxes pursuant to ASC 740, Income Taxes (“ASC 740”), which requires, among other things, an asset and liability approach to calculating deferred income taxes. The asset and liability approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. A valuation allowance is provided to offset any net deferred tax assets for which management believes it is more likely than not that the net deferred tax asset will not be realized. The Company follows the provision of ASC 740 related to accounting for uncertain income tax positions. When tax returns are filed, it is more likely than not that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. In accordance with the guidance of ASC 740, the benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely that not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. The tax benefits recognized in the consolidated financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with the tax positions taken that exceeds the amount measured as described above should be reflected as a liability for uncertain tax benefits in the Company’s balance sheets along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The most critical estimate for income taxes is the determination of whether to record a valuation allowance for any net deferred tax asset, including net loss carryforwards, whereby management must estimate whether it is more likely than not that the deferred tax asset would be realized.

Assets Acquired and Liabilities Assumed in a Business Combination

The Company accounts for business combinations under the acquisition method of accounting in accordance with ASC 805 - Business Combinations, by recognizing the identifiable tangible and intangible assets acquired and liabilities assumed, measured at the acquisition date fair value. The determination of fair value involves assumptions,estimates and judgments. Any purchase consideration in excess of the estimated fair values of net assets acquired is recorded as goodwill.

Goodwill Impairment

Goodwill is not subject to amortization, and instead, assessed for impairment annually, or more frequently when events or changes in circumstances indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount in accordance with ASC 350.
