Context

• This sale was a routine tax-withholding sale tied to vesting and executed under a 10b5-1 plan, which is a prearranged program that allows insiders to sell shares according to a preset schedule. Such sales generally do not signal a change in insider sentiment the way voluntary, discretionary sales might.
