| Adjustment To PEO Compensation, Footnote | The amounts listed in this column represent the amount of “compensation actually paid” to Mr. Comparato, in accordance with Item 402(v) of Regulation S-K. These amounts do not reflect the amount of actual compensation earned by or paid to Mr. Comparato in the applicable year.

| Compensation Actually Paid vs. Total Shareholder Return | Compensation Actually Paid and Cumulative TSR As demonstrated by the following graph, the amount of compensation actually paid to Mr. Comparato and the average amount of compensation actually paid to our named executive officers as a group (excluding Mr. Comparato) is generally aligned with our cumulative TSR over the three years presented in the table. The general alignment of compensation actually paid with our cumulative TSR over the period presented is because a significant portion of the compensation actually paid to Mr. Comparato and to the other named executive officers is comprised of equity awards, the value of which is tied directly to our stock price. Please refer to “Executive Compensation - Compensation Discussion and Analysis,” for information about our executive compensation programs. | | |
| Compensation Actually Paid vs. Net Income | Compensation Actually Paid and Net Income As demonstrated by the following graph, the amount of compensation actually paid to Mr. Comparato and the average amount of compensation actually paid to our named executive officers as a group (excluding Mr. Comparato) is not aligned with our net income results over the three years presented in the table. Our net income performance improved over the three year period reported in the table while the compensation actually paid to Mr. Comparato and the other named executive officers declined over the first two years of the same period. The lack of alignment of compensation actually paid with our net income over the period presented is because a significant portion of the compensation actually paid to Mr. Comparato and to the other named executive officers is comprised of equity awards, the value of which is tied directly to our stock price, and net income is not used as a metric in the Company’s compensation arrangements. Please refer to “Executive Compensation - Compensation Discussion and Analysis,” for information about our executive compensation programs. | | |
| Compensation Actually Paid vs. Company Selected Measure | Compensation Actually Paid and Adjusted EBITDA As demonstrated by the following graph, the amount of compensation actually paid to Mr. Comparato and the average amount of compensation actually paid to our named executive officers as a group (excluding Mr. Comparato) is aligned with our Adjusted EBITDA results over the three years presented in the table. Our 2022 short-term incentive bonus plan included Adjusted EBITDA %, which is derived from Adjusted EBITDA, as a bonus financial funding metric. Our 2023 short-term incentive bonus plan also includes Adjusted EBITDA as a bonus financial funding metric. Although the graph below shows alignment between compensation actually paid and our Adjusted EBITDA results over the period presented, the primary reason for the decline in compensation actually paid to Mr. Comparato and to the other named executive officers between the first and second years of the three year period is because a significant portion of the compensation actually paid to Mr. Comparato and to the other named executive officers is comprised of equity awards, the value of which is tied directly to our stock price. Please refer to “Executive Compensation - Compensation Discussion and Analysis,” for information about our executive compensation programs. | | |
| Total Shareholder Return Vs Peer Group | Cumulative TSR of the Company and Cumulative TSR of the Peer Group As demonstrated by the following graph, the Company’s cumulative TSR over the period presented in the table was (29%), while the cumulative TSR of the peer group presented for this purpose, the S&P 500 IT Index, was 25% over the same period. Our stock price performance was below that of the S&P 500 IT Index. Following our initial public offering in September 2021, we believe our stock price was subject to greater market volatility than the stock prices for technology companies in the S&P 500 IT Index since companies in the index had been in operation and trading publicly for longer periods of time. | | |
