Cautionary Note Regarding Forward-Looking Statements
Statements in this Current Report on Form 8-K about future expectations, plans, and prospects, as well as any other statements regarding matters that are not historical facts, may constitute “forward-looking statements” within the meaning of The Private Securities Litigation Reform Act of 1995. These statements include, but are not limited to, statements relating to the completion, size and timing of the offering, the anticipated use of any proceeds from the offering, and the terms of the notes. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “should,” “target,” “will,” “would,” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Actual results may differ materially from those indicated by such forward-looking statements as a result of various important factors, including uncertainties related to market conditions and the completion of the offering on the anticipated terms or at all, the other factors discussed in the “Risk Factors” section of TeraWulf’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 3, 2025 and the risks described in other filings that TeraWulf may make from time to time with the SEC. Any forward-looking statements contained in this Current Report on Form 8-K speak only as of the date hereof, and TeraWulf specifically disclaims any obligation to update any forward-looking statement, whether as a result of new information, future events, or otherwise, except to the extent required by applicable law.
