potential tax liabilities for beneficial owners of Shares without receiving corresponding distributions from the Trust in connection with Staking;

the Trust’s reliance on third-party service providers to perform certain functions essential to the affairs of the Trust and the challenges replacement of such service providers could pose to the safekeeping of the Trust’s SUI and to the operations of the Trust; and

the Custodian’s possible resignation or removal by the Sponsor or otherwise, without replacement, which could trigger early termination of the Trust.

Consequently, all forward-looking statements made in this prospectus are qualified by these cautionary statements, and there can be no assurance that the actual results or developments the Sponsor anticipates will be realized or, even if substantially realized, that they will result in the expected consequences to, or have the expected effects on, the Trust’s operations or the value of the Shares. Should one or more of these risks discussed in “Risk Factors” in this prospectus, or other uncertainties materialize, or should underlying assumptions prove incorrect, actual outcomes may vary materially from those described in forward-looking statements. Forward-looking statements are made based on the Sponsor’s beliefs, estimates and opinions on the date the statements are made and neither the Trust nor the Sponsor is under a duty or undertakes an obligation to update forward-looking statements if these beliefs, estimates and opinions or other circumstances should change, other than as required by applicable laws. Moreover, neither the Trust, the Sponsor, nor any other person assumes responsibility for the accuracy and completeness of any of these forward-looking statements. Investors are therefore cautioned against relying on forward-looking statements.
