This purchase equals about 11% of the average reported total pay of the company's named executive officers other than the CEO, fiscal 2025 ($8.07M)

An average across the officers named in the pay versus performance table of the company's proxy statement (DEF 14A), filed 2026-04-30. This person may not be one of them, so it is not their own pay. A size comparison, not a judgement
