(1)Beginning in the first quarter of 2025, the Company is excluding payroll tax expense related to stock-based compensation from Adjusted EBITDA because these taxes are directly related to stock-based compensation expense which is excluded from Adjusted EBITDA. The Company did not retrospectively apply this change to prior periods as the impact was immaterial to such periods. In the three and six months ended June 30, 2024 payroll tax expense related to stock-based compensation was $3.1 million and $4.1 million, respectively.
