Ive personally met him twice and he’s always been an extremely engaging and cordial person who genuinely make an effort to engage with a broad range of stakeholders.
He started in 2016 so leaving in 2022 makes it a 6 year innings. That’s not unusual in the corporate world to then want to move onwards and upwards to the next challenge. I worry more about the ones who are old, stale and uninspiring and stick around well past their used by date with no fresh ideas, experience or perspective.
