Disclaimer Cautionary Note Regarding Forward-Looking Information This presentation includes “forward-looking information” and “forward-looking statements” within the meaning of Canadian securities laws and United States securities laws, respectively (collectively, “forward looking information”). All information, other than statements of historical facts, included in this presentation that address activities, events or developments Hut 8 Corp. (“Hut 8” or the “Company”) expects or anticipates will or may occur in the future, including statements relating to the Company’s AI data center lease at River Bend, the total lease contract value over the lease term with and without extensions, the Company’s plan to implement and institutional-grade execution model designed to de-risk the project, expected NOI contribution of the lease, the potential extension of the lease term for up to three additional terms of five years each, Google’s commitment to backstop of the lease payments and related pass-through obligations under the lease, the anticipated delivery timeline for the site, the Company’s anticipated financing plan for the project, the potential execution of an additional Operations Services Agreement backed by an additional Google backstop of payment obligations, the Company’s potential expansion plans for the River Bend site, the Company’s development pipeline, and the Company’s future business strategy, competitive strengths, expansion, and growth of the business and operations more generally, and other such matters is forward-looking information. Forward-looking information is often identified by the words “may”, “would”, “could”, “should”, “will”, “intend”, “plan”, “anticipate”, “allow”, “believe”, “estimate”, “expect”, “predict”, “can”, “might”, “potential”, “predict”, “is designed to”, “likely,” or similar expressions. In addition, any statements in this presentation that refer to expectations, projections or other characterizations of future events or circumstances contain forward-looking information. Statements containing forward-looking information are not historical facts, but instead represent management’s expectations, estimates, and projections regarding future events based on certain material factors and assumptions at the time the statement was made. While considered reasonable by Hut 8 as of the date of this presentation, such statements are subject to known and unknown risks, uncertainties, assumptions and other factors that may cause the actual results, level of activity, performance, or achievements to be materially different from those expressed or implied by such forward-looking information, including, but not limited to, risks relating to the construction of new data centers, including cost overruns, delays, supply chain issues, permitting or regulatory hurdles, unexpected technical challenges, and dependency on contractors; risks relating to the financing of new data centers, including the potential dilutive impact of equity issuances (if any), access to capital markets, timing and cost of financing, and market conditions such as increases in interest rates, declining equity valuations, volatility in credit markets, or tightening lending standards; risks impacting our ability to expand the power capacity at the River Bend campus, such as limitations of transmission and/or generation resources; failure of critical systems; geopolitical, social, economic, and other events and circumstances; competition from current and future competitors; risks related to power requirements; cybersecurity threats and breaches; hazards and operational risks; changes in leasing arrangements; Internet-related disruptions; dependence on key personnel; having a limited operating history; attracting and retaining customers; entering into new offerings or lines of business; price fluctuations and rapidly changing technologies; predicting facility requirements; strategic alliances or joint ventures; operating and expanding internationally; failing to grow hashrate; purchasing miners; relying on third-party mining pool service providers; uncertainty in the development and acceptance of the Bitcoin network; Bitcoin halving events; competition from other methods of investing in Bitcoin; concentration of Bitcoin holdings; hedging transactions; potential liquidity constraints; legal, regulatory, governmental, and technological uncertainties; physical risks related to climate change; involvement in legal proceedings; trading volatility; and other risks described from time to time in Company’s filings with the U.S. Securities and Exchange Commission. In particular, see the Company’s recent and upcoming annual and quarterly reports and other continuous disclosure documents, which are available under the Company’s EDGAR profile at sec.gov and SEDAR+ profile at sedarplus.ca. These factors are not intended to represent a complete list of the factors that could affect Hut 8; however, these factors should be considered carefully. There can be no assurance that such estimates and assumptions will prove to be correct. Should one or more of these risks or uncertainties materialize, or should assumptions underlying the forward-looking statements prove incorrect, actual results may vary materially from those described in this presentation as intended, planned, anticipated, believed, sought, proposed, estimated, forecasted, expected, projected or targeted and such forward-looking statements included in this presentation should not be unduly relied upon. The impact of any one assumption, risk, uncertainty, or other factor on a particular forward-looking statement cannot be determined with certainty because they are interdependent and Hut 8’s future decisions and actions will depend on management’s assessment of all information at the relevant time. The forward-looking statements contained in this presentation are made as of the date of this presentation, and Hut 8 expressly disclaims any obligation to update or alter statements containing any forward-looking information, or the factors or assumptions underlying them, whether as a result of new information, future events or otherwise, except as required by law. Except where otherwise indicated herein, the information provided herein is based on matters as they exist as of the date of preparation and not as of any future date and will not be updated or otherwise revised to reflect information that subsequently becomes available, or circumstances existing or changes occurring after the date of preparation. No Offer or Solicitation This presentation is not intended to and shall not constitute an offer to sell or the solicitation of an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended (the “Securities Act”) or in a transaction exempt from the registration requirements of the Securities Act. Non-GAAP Financial Measures This presentation includes a non-GAAP financial measure, expected net operating income (NOI) contribution, which the Company defines as expected lease revenue for a particular lease less any non-reimbursable operating expenses attributable to the leased property. The Company’s management team uses expected NOI contribution to measure the expected operating performance of a particular lease. Operating income is the GAAP measure most directly comparable to expected NOI contribution. In evaluating expected NOI contribution, you should be aware that in the future the Company may incur non-reimbursable lease operating expenses that are not currently known. The Company’s presentation of expected NOI contribution should not be construed as an inference that its future results will be unaffected by unusual or non-recurring items. Expected NOI contribution has important limitations as an analytical tool and you should not consider expected NOI contribution in isolation or as a substitute for analysis of results as reported under GAAP. For example, expected NOI contribution excludes the impact of selling, general and administrative expenses and depreciation and amortization, which have real economic effect and could materially impact the Company’s consolidated financial results. Other companies, including Real Estate Investment Trusts, may calculate expected NOI contribution differently than the Company does and, accordingly, the Company’s expected NOI contribution may not be comparable to similar measures published by such companies. No reconciliation of expected NOI contribution is included in this press release because the Company is unable to quantify certain amounts that would be required to be included in operating income without unreasonable efforts as such quantification would imply a degree of precision that would be confusing or misleading to investors. Third Party Information This presentation includes market and industry data which was obtained from various publicly available sources and other sources believed by Hut 8 be true. Although Hut 8 believes it to be reliable, it has not independently verified any of the data from third party sources referred to in this presentation or analyzed or verified the underlying reports relied upon or referred to by such sources, or ascertained the underlying assumptions relied upon by such sources. Hut 8 does not make any representation as to the accuracy of such information.
