Gemini Space Station, Inc.

During the three months ended June 30, 2026, no director or Section 16 officer adopted, modified orterminated any Rule 10b5-1 trading arrangements or non-Rule 10b5-1 trading arrangements, as each term is defined in Item 408 of Regulation S-K, except for the following:

On May 18, 2026, the Company adopted an automatic sell-to-cover policy (the “Automatic Sell-to-Cover Policy”) that is intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act. The Automatic Sell-to-Cover Policy applies to all employees—including Section 16 officers—for whom the Company can legally and administratively satisfy applicable tax withholding obligations through automatic sell-to-cover transactions and provides for the mandatory sale of shares of Class A common stock otherwise issuable upon the vesting and settlement of equity grants made under the Company’s 2025 Omnibus Incentive Plan (as may be amended from time to time, and any successor plan or plans providing for the grant of equity awards to service providers to the Company or any subsidiary) in an amount sufficient to cover the federal, state, local and foreign tax withholding obligations incurred in connection with such vesting and settlement. The actual number of shares to be sold will vary based on futures events, including applicable tax withholding rates and the market price of the Class A common stock. The Automatic Sell-to-Cover Policy has no durational limit.
