Context

• This was a routine tax-withholding event tied to RSU vesting (cashless-like withholding), which is common and does not necessarily indicate the insider is reducing an investment position via open-market sales. For market-sentiment signals, open-market purchases or voluntary sales are typically more informative than tax-withholding dispositions.
