Compensation Actually Paid vs. Total Shareholder Return The following graph shows the relationship between the “compensation actually paid” to our CEO and the
average “compensation actually paid” to our Other NEOs and our reported annual net (loss) income for each
Covered Year. We do not currently use net (loss) income as a financial performance measure in our
executive compensation program.

Compensation Actually Paid vs. Net Income The following graph shows the relationship between the “compensation actually paid” to our CEO and the
average “compensation actually paid” to our Other NEOs and our reported annual revenue for each Covered
Year. The growth of annual revenue is a significant performance target in the Bonus Plan for our named
executive officers in the fiscal year ended December 31, 2025 and impacts the amount of annual cash bonus
that our named executive officers receive in the fiscal year.

Compensation Actually Paid vs. Company Selected Measure The following graph shows the relationships between the “compensation actually paid” to our CEO and the
average “compensation actually paid” to our Other NEOs, the cumulative TSR for our Series A common
stock, and the cumulative TSR for our peer group each Covered Year.

Total Shareholder Return Vs Peer Group The following graph shows the relationship between the “compensation actually paid” to our CEO and the
average “compensation actually paid” to our Other NEOs and our reported annual net (loss) income for each
Covered Year. We do not currently use net (loss) income as a financial performance measure in our
executive compensation program.

PEO Name Andrew Bialecki    
Additional 402(v) Disclosure For purposes of the adjustments to determine “compensation actually paid,” we computed the fair value of the RSUs awards in
accordance with FASB ASC Topic 718 as of the end of the relevant fiscal year, other than the fair values of equity awards that
vested in the Covered Year, which are valued as of the applicable vesting date. The valuation assumptions used in the calculation of
such amounts (as updated for purposes of this disclosure to reflect the relevant dates for purposes of calculating fair value) are set
forth in note 2 to our audited consolidated financial statements included in the 2025 Annual Report.
Reflects “Net (loss) income” for each Covered Year as set forth in our consolidated statements of operations included in our
Annual Report on Form 10-K for each of the Covered Years. For the avoidance of doubt, “Net (loss) income” is a GAAP measure.
Reflects “Revenue” for each Covered Year as set forth in our consolidated statements of operations included in our Annual Report
on Form 10-K for each of the Covered Years. For the avoidance of doubt, “Revenue” is a GAAP measure. The Company
determined that revenue is the financial performance measure that, in the Company’s assessment, represents the most important
financial performance measure used to link compensation actually paid to our named executive officers for the most recently
completed fiscal year to Company performance. We utilize revenue as a performance metric in our Bonus Plan.
