Context

• This was a compensation-related vesting of performance shares, not an open-market purchase or routine sale; the surrender of shares to cover taxes is common and does not itself indicate a change in investment view.
• For retail investors, awards reflect company compensation outcomes (here tied to three-year TSR relative to the S&P 500) rather than a direct buy/sell signal from the insider.
