Context

• This was a withholding to cover tax liability on vested RSUs, a common administrative action and not a directional trade signal. It reduces the insider’s outstanding shares but does not represent a market sale or purchase.
• For retail investors: tax-withholding events are routine and typically less informative about insider sentiment than open-market purchases or sales.
