Grayscale Investments Sponsors, LLC intends to enter into an amendment to the Grayscale Sui Staking ETF Trust Agreement on or around August 7, 2026. The proposed amendment would require the Trust to commence regular distributions of net cash proceeds from staking rewards to shareholders. To facilitate this, the Trust will reduce its Staking Consideration held in cash no less often than quarterly and distribute the proceeds net of Trust expenses. The specific distribution amounts are not predetermined and will depend on the Staking Consideration received during each period. This change aims to conform to IRS Revenue Procedure 2025-31 regarding grantor trust classification. The company operates in the digital asset investment management industry.
