 employment records and the methodology described below.

We identified our median employee using our employee population as of April 1, 2024. As permitted by the SEC's pay ratio rules, we used the same median employee to calculate our fiscal 2025 pay ratio that we used to calculate our fiscal 2024 pay ratio, as we believe that there have been no changes in our employee population or employee compensation arrangements that would result in a significant change to our pay ratio disclosure. See our 2024 proxy statement for information regarding the process we utilized to identify our "median employee."

– Our CEO's total annual compensation for fiscal 2025, calculated pursuant to SEC rules, was $10,229,945.

– Our median employee's total annual compensation for fiscal 2025, calculated pursuant to SEC rules, was $112,956.

– The resulting CEO pay ratio for fiscal 2025 is approximately 91:1.

The SEC rules for identifying the median compensated employee and calculating the CEO pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their compensation practices. As such, the CEO pay ratio reported by other companies, including in our own industry, may not be comparable to the CEO pay ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own CEO pay ratios.

Our Summary Compensation Tables disclose the total compensation paid to our PEOs and Other NEOs during the reported fiscal years, including the grant date fair value of stock-based awards granted during each fiscal year. As detailed further below, CAP for our PEOs and Other NEO
