Context

• This was not an open-market sale or purchase signal: it reflects PSUs vesting (an award) with a routine share withholding to cover taxes—a common administrative action that does not necessarily indicate a change in the insider’s market view.
• For retail investors, awards and tax withholdings are typically less informative about insider sentiment than outright purchases or large voluntary sales.
