Grayscale Sui Trust

Grayscale Sui Staking ETF is a Delaware Statutory Trust formed on April 30, 2024. The Trust's primary purpose is to hold Sui tokens ("SUI"), which are digital assets created and transmitted via the peer-to-peer Sui Network. This network is a decentralized system of computers operating on cryptographic protocols. As of December 31, 2025, the Trust holds approximately 0.08% of the SUI in circulation. The Trust's position size does not allow its Sponsor or the Trust to participate in or influence the development of the Sui Network. The Sui Network is a decentralized digital asset network with various stakeholders, including core SUI developers, users, services, businesses, validators, and other groups, with the Trust being one such constituent. Ownership of SUI does not grant rights to participate in the governance of the network. On February 17, 2026, the Trust changed its name from Grayscale Sui Trust (SUI) to Grayscale Sui Staking ETF. Since its inception and before listing its Shares on NYSE Arca, the Trust issued common units of fractional undivided beneficial interest ("Shares"), representing ownership in the Trust, periodically to "accredited investors" as defined by Rule 501(a) of Regulation D under the Securities Act of 1933, as amended, in exchange for SUI deposits.
