Context

• These were vested RSUs converted to shares and sold; part of the sale primarily addressed tax withholding obligations and was executed under a written plan (10b5-1) to provide an affirmative defense. Such sales are commonly routine tax or liquidity transactions and do not, by themselves, indicate the insider’s view of the company’s long-term prospects.
