#### CEO PAY RATIO
Under SEC rules, we are required to provide a reasonable estimate of the ratio of the annual total compensation of Mr. Calkins, our CEO, to the median of the annual total compensation of our other employees. We identified the employee with annual total compensation at the median of the compensation of all of our employees (the “Median Employee”) by considering our employee population as of December 31, 2024 (the “Employee Population Determination Date”). We considered all individuals, excluding our CEO, who were employed by us (including our consolidated subsidiaries) on the Employee Population Determination Date, whether employed in the U.S. or outside the U.S., or on a full-time or part-time basis, including employees on a leave of absence. Contractors, interns, and other non-employees were not included in our employee population. The total number of our U.S. and non-U.S. employees considered for the calculation was 2,033.

To identify the Median Employee from the employee population described above, we determined each employee's compensation as the sum of the following components:

• Base pay - For hourly employees, base pay is calculated as the hourly rate in effect on December 31, 2024 multiplied by a reasonable estimate of hours worked during the year. For salaried employees, base pay is calculated as annual base salary in effect on December 31, 2024 regardless of the employee's hire date.
