Context
Insider sales are common and do not necessarily signal a change in company fundamentals; purchases are generally viewed as a stronger bullish signal. This filing reports a straightforward sale by an executive and does not indicate an option exercise, gift, or tax-withholding event. The filing does not identify the insider as a 10% owner.
