(1) Represents shares issuable to Mr. Spice upon the exercise of all outstanding vested stock options held by Mr. Spice as of the date of the Rule 10b5-1 Trading Plan, all of which are scheduled to expire in August 2028.
(2) The aggregate number of RSU Shares that will be available for sale under the Rule 10b5-1 Trading Plan is not yet determinable because the shares available will be net of shares sold to satisfy tax withholding obligations that arise in connection with the vesting and settlement of such RSU awards. Additionally, certain provisions within the Rule 10b5-1 Trading Plan specify a certain percentage of the net shares that can be sold at the vesting date of the underlying equity award. As such, for purposes of this disclosure, the shares included in this table reflect the aggregate maximum number of gross shares underlying the equity awards subject to the Rule 10b5-1 Trading Plan, adjusted to represent the maximum percentage specified in the plan for each vesting date of such award, but without excluding the shares that will be sold to satisfy the tax withholding obligations.
On June 3, 2026, Mr. Spice terminated his Rule 10b5-1 trading plan, originally adopted on March 27, 2026. No shares of common stock were sold pursuant to Mr. Spice’s terminated 10b5-1 trading plan.
