- F1: RSUs granted under the 2014 Incentive Plan; these RSUs vest in 33.3% increments on March 15, 2027–2029 and convert to one share per RSU.
- F2: Some units are performance-based RSUs that vested.
- F3: Shares were withheld to pay tax withholding requirements on vesting (routine).

Context

These were restricted stock unit awards (not open-market purchases). The disposal was a company/plan tax-withholding action (common when RSUs vest), not an open-market sale that signals sentiment. RSU grants reflect compensation and vesting schedules; withheld shares to cover taxes are routine and do not necessarily indicate buying or selling intent.
