Mr. Blachar has served as the PEO since July 1, 2020 and for the entirety of 2023, 2022, 2021 and 2020. Mr. Angel is labeled as “PEO 1” and Mr. Blachar as “PEO 2.” Our other NEOs for the applicable fiscal years are labeled as “Other NEOs” and are as follows:

	•	2023: Assaf Ginzburg, Shimon Hatzir, Ofer Ben Yosef and Jessica Woelfel.
	•	2022: Assaf Ginzburg, Shlomi Argas, Shimon Hatzir and Ofer Ben Yosef.

Amounts reported in these columns represent (i) the total compensation reported in the Summary Compensation Table (“SCT”) for the applicable year in the case of Mr. Angel (PEO 1 for 2020) and Mr. Blachar (PEO 2 for 2020, and otherwise the sole PEO for subsequent years), and (ii) the average of the total compensation reported in the SCT for the applicable year for our Other NEOs.

(3)

Amounts reported in these columns represent the amount of “Compensation Actually Paid” (“CAP”) as computed in accordance with Item 402(v) of Regulation S-K. A reconciliation of the adjustments for PEOs and for the average of the Other NEOs is set forth in the following table. The CAP amounts do not reflect the actual amount of compensation earned by or paid to the PEOs or Other NEOs in the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to each applicable executive officer’s total compensation reported in the SCT for each year to determine the CAP:

TABULAR LIST OF MOST IMPORTANT FINANCIAL PERFORMANCE MEASURES

The following is a list of performance measures, which in our assessment represent the most important performance measures used by the Company to link NEO compensation to Company performance. Each performance metric below is used for purposes of determining payouts under either our Management Plan or vesting of our PSUs. Please see “Compensation Discussion and Analysis” for a further description of these performance metrics (including, in the case of Adjusted EBITDA, how it is calculated) and how they are used in our executive compensation program. As noted above, we do not in practice use any performance measures to link “compensation actually paid” (as calculated herein) to Company performance. However, we are providing this list in accordance with Item 402(v) of Regulation S-K to provide information on performance measures used by the Compensation Committee to determine NEO compensation, as more fully described in “Compensation Discussion and Analysis.”
