Context

• These entries are award vesting and tax-withholding transactions (transaction codes A and F). The withheld shares are routine tax-withholding (common when RSUs or performance shares vest) and should not be interpreted the same as an executive selling shares on the open market.
• The performance-share payout was certified by the compensation committee, which is why performance shares vested on March 5, 2026. This filing documents compensation-related equity vesting rather than a directional bet by the insider.
