Context

• Withholding shares to cover taxes upon RSU vesting is common and reported as a disposition (F). It is a routine administrative action and does not necessarily signal the insider is reducing economic exposure via a market sale.
• For retail investors, purchases or open-market sales by insiders can be more informative about sentiment; tax-withholdings on vesting are typically neutral operational events.
