The Choi Plan provides for the sale of shares of Class A common stock (i) net of certain shares sold pursuant to Ms. Choi’s prior Rule 10b5-1 Plan dated August 12, 2025 (the “Prior Choi Plan”), (ii) to be received upon the future grant, vesting and settlement of certain restricted stock units, and (iii) to be received upon the future vesting and settlement of certain outstanding restricted stock units and performance restricted stock units, net of any shares withheld or mandatorily sold by the Company to satisfy applicable tax obligations. The number of shares (i) to be sold under the Prior Choi Plan, (ii) to be received by Ms. Choi upon the future grant, vesting, and settlement of restricted stock units for shares of Class A common stock, and (iii) to be withheld or mandatorily sold by the Company, and therefore the exact number of shares to be sold pursuant to the Choi Plan, can only be determined upon the occurrence of future events. For purposes of this disclosure, we have included the maximum aggregate number of shares to be sold without (i) subtracting any shares sold under the Prior Choi Plan, (ii) including any shares to be sold upon the future vesting and settlement of any restricted stock units that have not yet been granted, and (iii) subtracting any shares to be withheld or mandatorily sold by the Company upon future vesting events.
