Context
These sales were executed under a pre-established 10b5‑1 plan to cover tax withholding for vested RSUs, which is a common, routine reason for insider sales and not necessarily a directional signal about the company. For investors, purchases or unscheduled sales by insiders can be more informative; this filing reflects a tax-driven disposition rather than an opportunistic market trade.
