Forward-Looking Statements

This Current Report on Form 8-K contains certain forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact included in this Current Report on Form 8-K, including statements regarding the Company’s future financial condition, results of operations, business operations and business prospects, are forward-looking statements. These statements are identified by the use of the words “could,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “may,” “continue,” “predict,” “potential,” “project” and similar expressions that are intended to identify forward-looking statements. All forward-looking statements are subject to important factors, risks, uncertainties, and assumptions, including industry and economic conditions that could cause actual results to differ materially from those described in the forward-looking statements. Such factors, risks, uncertainties and assumptions include, but are not limited to, the Company’s ability to successfully achieve its strategic initiatives, including its expectation that it will be able to secure additional miners; unexpected costs, charges or expenses resulting from the Acquisition; potential adverse reactions or changes to business relationships resulting from the completion of the Acquisition; risks related to the inability of the Company to successfully operate as a combined business; risks associated with the possible failure to realize certain anticipated benefits of the Acquisition, including with respect to future financial and operating results; competition in the Company’s markets; risks associated with the Company’s investment strategy, including digital asset market volatility, cybersecurity and custody of digital assets, potential changes in laws or accounting standards relating to digital assets and regulatory developments affecting digital assets; and volatility of the Company’s stock price. Forward-looking statements also are affected by the risk factors described in the Company’s filings with the U.S. Securities and Exchange Commission, including in the Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K. The risks and uncertainties that the Company has described are not the only ones the Company faces. Additional risks and uncertainties not presently known to the Company or that the Company currently deems immaterial may also affect the Company’s operations. All forward-looking statements speak only as of the date of this Current Report on Form 8-K. You should not place undue reliance on these forward-looking statements. Although the Company believes that its plans, objectives, expectations and intentions reflected in or suggested by the forward-looking statements are reasonable, it can give no assurances that these plans, objectives, expectations or intentions will be achieved. Forward-looking statements involve significant risks and uncertainties (some of which are beyond the Company’s control) and assumptions that could cause actual results to differ materially from historical experience. Actual results may differ materially from those in the forward-looking statements and the trading price for the Company’s common stock may fluctuate significantly Except as required by law, the Company undertakes no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, after the date on which the statements are made or to reflect the occurrence of unanticipated events.
