Context

• This sequence shows equity awarded/issued (RSUs/PSUs) and the routine mechanics that follow: shares were withheld to satisfy tax obligations and a portion was sold under a pre-existing 10b5-1 plan. Withholding for taxes and sales pursuant to a trading plan are common post-vesting actions and do not by themselves indicate stewardship intent beyond liquidity/tax needs.
• Transaction codes: A = Award/Grant, F = payment of exercise price or tax liability (withholding), S = Sale (open market).
