Context
- Because the exercise and sale involve the same share count on the same day, this looks like an immediate disposition following exercise (commonly done to cover exercise cost and tax withholding), but the filing simply reports the transactions — it does not state Eckert’s intent.
- The transaction was executed under a 10b5-1 plan, which generally means the trades were pre-planned and automated rather than ad hoc.
