Grayscale Investments Sponsors, LLC intends to enter into a Third Amended and Restated Declaration of Trust and Trust Agreement for the Grayscale Solana Staking ETF on or around August 7, 2026. The proposed amendment would require the Trust to reduce its Staking Consideration to cash no less often than quarterly and distribute the net cash proceeds of staking rewards to shareholders. This change aims to conform to IRS Revenue Procedure 2025-31 to maintain the Trust's classification as a grantor trust for U.S. federal income tax purposes. The specific amount of future distributions remains uncertain as they depend on the Staking Consideration received during each period. The company operates in the digital asset investment management industry.

Grayscale Investments Sponsors, LLC announced the appointment of Kathryn Masci and Daniel Plourde as interim Co-Chief Financial Officers, succeeding Edward McGee, effective July 2, 2026. Ms. Masci will also serve as a member of the Board of Managers and Principal Financial and Accounting Officer of the registrant. Mr. McGee is stepping down for personal reasons and is leaving on good terms. Grayscale operates in the digital asset investment management industry.

Grayscale Solana Staking ETF entered into Amendment No. 3 to its Trust Agreement on June 25, 2026, reducing the annual Sponsor's Fee from 0.35% to 0.19% of the aggregate value of the Trust's assets. Additionally, the Sponsor's Staking Fee was reduced from 23% to 7% of gross Staking Consideration generated under the Staking Arrangements, effective the same day. The company operates in the digital asset investment management industry through its Solana-based staking ETF.
