Context

• This was not an open-market sale or purchase by the insider; it reflects vesting/settlement of awards (RSUs and PSUs) and a routine withholding of shares to satisfy tax obligations (a common "sell-to-cover" mechanism). These filings document compensation realization rather than an active buy or sell signaling sentiment.
