SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS AND INDUSTRY DATA

This Quarterly Report on Form 10-Q (this “Quarterly Report”) contains forward-looking statements which reflect our current views with respect to, among other things, our operations and financial performance. Such statements are based upon our current plans, estimates and expectations that are subject to various risks and uncertainties that could cause actual results to differ materially from such statements. The inclusion of forward-looking statements should not be regarded as a representation that such plans, estimates and expectations will be achieved. Words such as “anticipate,” “expect,” “project,” “intend,” “believe,” “may,” “will,” “should,” “plan,” “could,” “continue,” “target,” “contemplate,” “estimate,” “forecast,” “guidance,” “predict,” “possible,” “potential,” “pursue,” “likely,” and words and terms of similar substance used in connection with any discussion of future plans, actions or events identify forward-looking statements. All statements, other than historical facts, including statements regarding our future product development plans; the potential, safety, efficacy, and regulatory and clinical progress of our product candidates, including the anticipated timing for potential regulatory submissions, approvals and timing thereof; and any assumptions underlying any of the foregoing, are forward-looking statements. In addition, forward-looking statements address various matters including statements relating to the assets to be held by the Company, the expected future market, price and liquidity of the digital assets the Company acquires, the macro and political conditions surrounding digital assets, the Company’s plan for value creation and strategic advantages, market size and growth opportunities, regulatory conditions, competitive position and the interest of other corporations in similar business strategies, technological and market trends, and future financial condition and performance. Important factors that could cause actual results to differ materially from our plans, estimates or expectations could include, but are not limited to: (i) our ability and plan to develop and commercialize sirexatamab (DKN-01) and our other programs; (ii) status, timing and results of our preclinical studies and clinical trials; (iii) the potential benefits of sirexatamab and our other programs; (iv) the timing of our development programs and seeking regulatory approval of sirexatamab and our other programs; (v) our ability to obtain and maintain regulatory approval; (vi) our estimates of expenses and future revenues and profitability; (vii) our estimates regarding our capital requirements and our needs for additional financing; (viii) our estimates of the size of the potential markets for sirexatamab and our other programs; (ix) the benefits to be derived from any collaborations, license agreements, or other acquisition efforts; (x) sources of revenues and anticipated revenues, including contributions from any collaborations or license agreements for the development and commercialization of products; (xi) the rate and degree of market acceptance of sirexatamab or our other products; (xii) the success of other competing therapies that may become available; (xiii) the manufacturing capacity for our products; (xiv) our intellectual property position; and (xv) our ability to maintain and protect our intellectual property rights. Additional risks and uncertainties include, among others, the risk that the Company will fail to realize the anticipated benefits of the digital asset treasury strategy; changes in business, market, financial, political and regulatory conditions; risks relating to the Company’s operations and business, including the highly volatile nature of the price of digital assets; the risk that the price of the Company’s Common Stock may be highly correlated to the price of the digital assets that it holds; risks related to increased competition in the industries in which the Company does and will operate; risks relating to significant legal, commercial, regulatory and technical uncertainty regarding digital assets generally; risks relating to the treatment of crypto assets for U.S. and foreign tax purposes; and our ability to comply with the continued listing requirements of the Nasdaq Capital Market (“Nasdaq”).

By their nature, forward-looking statements involve risks and uncertainties because they relate to events, competitive dynamics and industry change, and depend on economic circumstances that may or may not occur in the future or may occur on longer or shorter timelines than anticipated. Although we believe that we have a reasonable basis for each forward-looking statement contained in this Quarterly Report, we caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity, and the development of the industry in which we operate may differ materially from the forward-looking statements contained in this Quarterly Report. In addition, even if our results of operations, financial condition and liquidity, and events in the industry in which we operate are consistent with the forward-looking statements contained in this Quarterly Report, they may not be predictive of results or developments in future periods. You should carefully and completely read this Quarterly Report and any documents that we have filed as exhibits to this Quarterly Report.

You should refer to Part II, Item 1A, Risk Factors in this Quarterly Report and Part I, Item 1A, Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the Securities and Exchange Commission on March 26, 2025, for a discussion of important factors that may cause our actual results to differ materially from those expressed or implied by our forward-looking statements. As a result of these factors, we cannot assure you that the forward-looking statements in this Quarterly Report will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking statements, you should not regard any such statement as a representation or warranty by us or any other person that we will achieve our objectives and plans in any specified timeframe, or at all. Any forward-looking statement that we make in this Quarterly Report speaks only as of the date of such statement, and, except to the extent required by applicable law, we undertake no obligation to update such statements to reflect events or circumstances after the date of this Quarterly Report or to reflect the occurrence of unanticipated events. You should, therefore, not rely on these forward-looking statements as representing our views as of any date subsequent to the date of this Quarterly Report. Comparisons of results for current and any prior periods are not intended to express any future trends or indications of future performance, unless expressed as such, and should only be viewed as historical data.

Sirexatamab (DKN-01) is an investigational drug undergoing clinical development and has not been approved by the U.S. Food and Drug Administration (the “FDA”), nor has it been submitted to the FDA for approval. Sirexatamab has not been, and may never be, approved by any regulatory agency or marketed anywhere in the world. Statements contained in this Quarterly Report should not be deemed to be promotional.
