Every Form 4 sale as filed, every proxy pay year, no matched open-market purchases; all captured filings, not complete lifetime history. Former officer Zachary K. Bradford's 2025 pay is 1.50% of the $3.26B market capitalization on Sep 4, 2026. Definitions

All captured retains imported filings across refreshes. Missing filings and periods before capture are not zero; this is not complete lifetime history. Coverage: ownership filings predate the window.
