Explanation of Responses:

( 1 )Represents performance-based restricted stock units (PSUs) originally granted on June 5, 2023, under the Issuer's 2021 Long-Term Incentive Plan. The PSUs were subject to achievement of specified internal financial performance metrics over a performance period ending December 31, 2025. The award provided for (i) 45,000 target units based on the Company's average Ex-TAC Gross Profit growth from January 1, 2024 through December 31, 2025 ("the Ex-TAC Target"), and (ii) 45,000 target units based on the cumulative percentage of Adjusted EBITDA to Ex-TAC Gross Profit over the period January 1, 2023 through December 31, 2025 ("the EBITDA Target"). On March 11, 2026, the Compensation Committee certified achievement of 100% of the Ex-TAC Target and 64.08% of the EBITDA Target, resulting in the issuance of 73,836 shares of common stock.
