Compensation Actually Paid vs. Total Shareholder Return [Text Block]

Compensation Actually Paid and Cumulative TSR

The following graph illustrates the amount of “compensation actually paid” (“CAP”) to Mr. Weil and the average amount of CAP to the Company’s NEOs as a group (excluding Mr. Weil) relative to the Company’s cumulative total shareholder return (TSR) over the three years presented in the table. A significant portion of the CAP is comprised of equity awards, with special sign-on awards granted in the 2021 year to Mr. Weil, Mr. Pierce and Mr. Baker as part of new employment agreements or extensions. Approximately 50% of the sign-on RSUs awarded to Mr. Weil were conditioned on attainment of stock price targets and approximately 25% were conditioned on attainment of Adjusted EBITDA targets.

Compensation Actually Paid vs. Net Income [Text Block]

Compensation Actually Paid and Net Income

As demonstrated by the following table, the amount of CAP to Mr. Weil and the average amount of CAP to the Company’s NEOs as a group (excluding Mr. Weil) is not aligned with the Company’s net income over the three years presented in the table. The Company has not used net income as a performance measure in the overall executive compensation program.

Compensation Actually Paid vs. Company Selected Measure [Text Block]

Compensation Actually Paid and Adjusted EBITDA

The Company utilizes Adjusted EBITDA when setting goals for the Company’s annual performance bonuses and for the performance-based RSUs that are awarded to the NEOs. Approximately 51% of the value of total compensation awarded for target level performance to the NEOs is in the form of performance-based bonuses and restricted stock units tied to Adjusted EBITDA.

[1] The dollar amounts reported in column (b) are the amounts of total compensation reported for Mr. Weil in the “Total” column of the Summary Compensation Table for each applicable year. Mr. Weil was our Principal Executive Officer (PEO) for all applicable years. The dollar amounts reported in column (d) represent the average of the amounts reported for our Named Executive Officers (NEOs), other than our PEO, in the “Total” column of the Summary Compensation Table in each applicable year. Our NEOs, other than our PEO, were as follows —for 2021, Mr. Pierce and Mr. Baker; for 2022, Mr. Pierce and Mr. Silvers; and for 2023, Mr. Pierce, Ms. Damon and Mr. Silvers. Refer to “Executive Compensation – Summary Compensation Table,” including footnote 3 which discusses certain revisions that were made to the historical amounts reported.

[2] The dollar amounts reported in column (c) represent the amount of “compensation actually paid” to Mr. Weil, as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts reported in column (e) represent the average amount of “compensation actually paid” to the NEOs, other than our PEO, as a group, as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to determine the “compensation actually paid” amounts reported above for the PEO and the average paid to the other NEOs:

[3] Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period.

[4] The amounts shown in the columns for net income and Adjusted EBITDA for 2021 and 2022 reflect the restated amounts reported in the restated financial statements of the Company contained in the Company’s Annual Report on Form 10-K/A for the fiscal year ended December 31, 2022 filed with the SEC on February 27, 2024.

[5] Adjusted EBITDA, a non-GAAP financial measure, is defined as net income (loss) excluding depreciation and amortization, interest expense, interest income and income tax expense, and other additional exclusions and adjustments. Such additional excluded amounts include stock-based compensation U.S. GAAP charges where the associated liability is expected to be settled in stock, and changes in the value of earnout liabilities and income and expenditure in relation to legacy portions of the business (being those portions where trading no longer occurs) including closed defined benefit pension schemes. Additional adjustments are made for items considered outside the normal course of business, including (1) restructuring costs, which include charges attributable to employee severance, management changes, restructuring, dual running costs, costs related to facility closures and integration costs, (2) merger and acquisition costs and (3) gains or losses not in the ordinary course of business. This does not include any adjustments related to COVID-19. While the Company uses numerous financial and non-financial performance measures for the purpose of evaluating performance for the Company’s compensation programs, the Company has determined that Adjusted EBITDA is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the company to link compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to Company performance. For a discussion of Adjusted EBITDA and a reconciliation of net income to Adjusted EBITDA, see pages 52 – 55 of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023.
