Context
The disposal combined a tax-withholding disposition tied to RSU vesting (not a discretionary sale) and a planned sale under a 10b5-1 trading plan. Tax-withheld share disposals are routine administrative actions; 10b5-1 sales are prearranged and do not necessarily signal a change in the insider’s view of the company.
