Item 1.01 Entry into a Material Definitive Agreement. Benchmark Licensing Agreement On August 20, 2026, 21Shares US LLC (the “Sponsor”) entered into a licensing agreement (the “Benchmark Licensing Agreement”) with FTSE International Limited (“FTSE” or the “Benchmark Provider”). Entry into the Benchmark Licensing Agreement follows the Sponsor’s notice, provided on June 30, 2026 and previously disclosed, of the termination, effective August 31, 2026, of the Sponsor’s licensing agreement with CF Benchmarks Ltd. relating to the use of the CME CF Sui-Dollar Reference Rate - New York Variant. Pursuant to the Benchmark Licensing Agreement, FTSE will provide each of the Sponsor, 21Shares Sui Staking ETF (the “Trust”), and their affiliates a non-exclusive, non-transferable, non-sub-licensable, worldwide license to access, view and use the FTSE Sui Index (the “Pricing Benchmark”) to develop, create, calculate, settle, maintain or support and market the Trust. Beginning August 27, 2026, the Trust will value its shares of beneficial interest (“Shares”) and calculate its net asset value by reference to the Pricing Benchmark in place of the CME CF Sui-Dollar Reference Rate - New York Variant. Such license is expected to have a one-year initial term and will automatically be renewed for successive one-year periods, unless terminated pursuant to its terms. FTSE is a company incorporated and registered in England, and its principal offices are located at 10 Paternoster Square, London, EC4M 7LS, United Kingdom. FTSE is experienced in calculating and administering digital asset indices. FTSE is unaffiliated with the Sponsor. Amendment No. 1 to the Sponsor Agreement On August 26, 2026, the Trust entered into Amendment No. 1 to the Sponsor Agreement, by and between the Trust and the Sponsor (the “Amendment No. 1 to the Sponsor Agreement”), to change the timing of payment of the sponsor fee the Sponsor receives from the Trust as compensation for the Sponsor’s services rendered to the Trust (the “Sponsor Fee”) from weekly in arrears to at least quarterly in arrears, in each case payable in SUI. The foregoing descriptions of the Benchmark Licensing Agreement and Amendment No. 1 to the Sponsor Agreement are summaries, do not purport to be complete, and are qualified in their entirety by reference to the full text of the Benchmark Licensing Agreement and Amendment No. 1 to the Sponsor Agreement, copies of which are filed as Exhibits 10.1 and 10.2 hereto, respectively, and are incorporated by reference herein.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

In addition, on August 26, 2026, the Sponsor and CSC Delaware Trust Company, the Trustee of the Trust, entered into a Second Amended and Restated Trust Agreement (the “Trust Agreement”). The Trust Agreement made changes to the Amended and Restated Trust Agreement to reflect (i) the Trust’s use of the FTSE Sui Index in place of the CME CF Sui-Dollar Reference Rate - New York Variant, (ii) the change in timing of payment of the Sponsor Fee, (iii) the change in the Trust’s name and (iv) various other ministerial, technical, conforming and clarifying revisions, none of which materially impact the rights of the Trust or holders of Shares.
