CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (the “Quarterly Report”) contains forward-looking statements. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements contained in this Quarterly Report, other than statements of historical fact, including, without limitation, statements about our beliefs and expectations regarding our future results of operations and financial position, planned business model and strategy, our bitcoin mining and high-performance compute (“HPC”) data center development, timing and likelihood of success, capacity, functionality and timing of operation of data centers, expectations regarding the operation of data centers, potential strategic initiatives, such as joint ventures and partnerships, and management plans and objectives are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “seeks,” “intends,” “targets,” “projects,” “contemplates,” “believes,” “estimates,” “forecasts,” “predicts,” “potential” or “continue” or the negative of these terms or other similar expressions, although not all forward-looking statements use these words or expressions. The forward-looking statements in this Quarterly Report are only predictions and are largely based on our current expectations and projections about future events and trends that we believe may affect our business, financial condition and results of operations. Forward-looking statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements, including, but not limited to, the following:

Risks Related to Our Business, Industry and Operations

•If we are unable to complete the construction of our HPC data centers in a timely manner or within our anticipated cost estimates, it could have a material adverse effect on our business, results of operations, liquidity and our ability to make payments on our outstanding indebtedness.

•Our business is exposed to construction risks, including risks arising from construction safety incidents.

•Our tenants’ guarantees and other backstop arrangements under our HPC leases will only be effective after rent commencement under such leases and are subject to certain limitations, like event of default triggers or caps.

•Our HPC business strategy may not perform as planned.

•Our business depends on the demand for data centers.

•Constructing data centers for HPC hosting requires significant capital expenditures, and we may be unable to secure capital or financing for our construction efforts to develop data centers for HPC hosting.

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

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

•Any failure of our physical or information technology or operational technology infrastructure or services could lead to significant costs and disruptions.

•We depend on tenants for our HPC data centers.

•Our business has grown rapidly and we have an evolving business model and strategy, which includes our diversification into constructing and operating data centers for HPC companies.

•The further development of AI technology, which represents a new and rapidly changing industry, is subject to a variety of factors that are difficult to evaluate. The slowing or stopping of the development of AI technology may adversely affect the demand for HPC-focused data center development and thus, adversely affect an investment in us.

•Any unfavorable global economic, business or political conditions, such as geopolitical tensions, military conflicts, acts of terrorism, natural disasters, pandemics, trade restrictions, tariffs, or similar events could have a material adverse effect on our business, financial condition and results of operations.

•Operating HPC data centers is energy-intensive, which may have a negative environmental impact. Changing environmental regulation and public energy policy may expose our business to new risks.

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

•We depend on third parties, including engineering, procurement and construction contractors, transmission and distribution utilities, grid operators, electric utility providers and manufacturers of certain critical and specialized equipment, and rely on skilled labor, components and raw materials that may be subject to price fluctuations or shortages.

•We are vulnerable to severe weather conditions and natural disasters, including severe heat, winter weather events, earthquakes, fires, floods, hurricanes, as well as power outages and other industrial incidents or mechanical failures, which could severely disrupt the normal operation of our business and adversely affect our results of operations.

•If we or our third-party providers fail to protect our information technology systems, digital assets or confidential information, or experience cybersecurity incidents, our business, operating results, financial condition and reputation could be materially harmed.

•Our business and operating results historically have been highly dependent on bitcoin and the Bitcoin ecosystem, which are volatile and subject to risks beyond our control.

Risks Related to HPC

•Any potential use of emerging technologies like artificial intelligence could lead to unintended consequences and result in reputational harm and litigation.

•Regulatory developments surrounding AI may negatively impact our HPC data center operations.

•We are subject to a highly-evolving regulatory landscape and any adverse changes to laws and regulations, including changes in government policies, permitting requirements or land use regulations resulting from community opposition to data center development, or our failure to comply with, any applicable laws and regulations could adversely affect our business, reputation, prospects or operations.

Risks Related to Regulatory Framework

•We may face electricity market risks relating to changes in laws, regulations and requirements of market operators, network operators and/or regulatory bodies, including with respect to interconnection of facilities of large electrical loads to the ERCOT grid, (including ERCOT’s batch study process for large load interconnection requests and related governmental reviews), grid stability, voltage ride-through, frequency ride-through and curtailment obligations.

•We are subject to environmental, health and safety laws and regulations, including applicable zoning, building-code and energy-efficiency standards and worker health and safety laws and regulations, and these laws and regulations and any changes to them may materially adversely affect our brand, reputation, business, results of operations and financial position.

Risks Related to Our Indebtedness

•Our indebtedness and liabilities could limit the cash flow available for our operations, expose us to risks that could adversely affect our business, financial condition and results of operations and impair our ability to satisfy our debt obligations.

•We may not be able to generate sufficient cash to service all of our indebtedness and to fund our working capital and capital expenditures, and may be forced to take other actions to satisfy our obligations under our indebtedness that may not be successful.

•Our debt agreements contain restrictions that will limit flexibility in operating our business.

•The important factors discussed in Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 filed with the Securities and Exchange Commission (the “SEC”) on February 24, 2026 (the “2025 Form 10-K”), as updated in our subsequent filings with the SEC, including this Quarterly Report on Form 10-Q, and any additional risks as described in our other reports filed with the SEC.

The forward-looking statements in this Quarterly Report are based upon information available to us as of the date of this Quarterly Report, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

You should read this Quarterly Report and the documents that we reference in this Quarterly Report and have filed as exhibits to this Quarterly Report with the understanding that our actual future results, performance and achievements may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements. These forward-looking statements speak only as of the date of this Quarterly Report. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained in this Quarterly Report, whether as a result of any new information, future events or otherwise.
