AI brief of an SEC Form 8-K · 21Shares Sui Staking ETF (TSUI)

21Shares Sui Staking ETF switches NAV benchmark to FTSE Sui Index from Aug 27

Neutral Impact 3 of 5 product/contract Written later

Starting August 27, 2026, the Trust will value its shares and calculate net asset value using the FTSE Sui Index instead of the CME CF Sui-Dollar Reference Rate - New York Variant, after the sponsor's license with CF Benchmarks ends August 31, 2026. The filing also changes the timing of the sponsor fee, which will now be paid at least quarterly in arrears instead of weekly, and renames the Trust from 21Shares Sui ETF to 21Shares Sui Staking ETF; the company says the other revisions do not materially affect shareholders' rights.

Key points

  • FTSE Sui Index replaces the CME CF Sui-Dollar Reference Rate - New York Variant for NAV calculations beginning August 27, 2026
  • Benchmark Licensing Agreement with FTSE International Limited is dated August 20, 2026, with a one-year initial term that renews automatically
  • Sponsor Fee moves from weekly to at least quarterly payment in arrears, still payable in SUI, under Amendment No. 1 dated August 26, 2026
  • Trust renamed on August 25, 2026 via Certificate of Amendment; Second Amended and Restated Trust Agreement signed August 26, 2026
