Context

• The disposal (code F) is a routine tax-withholding or exercise-price payment — common when options/awards vest or are exercised; it is not the same as an open-market sale intended to take profits.
• The derivative entry and F2 vesting schedule indicate option-like awards that vest/exercise over 2027–2029. The restricted shares vest in 2029.
• These entries reflect compensation-related equity activity by an executive rather than a straightforward purchase or investment signal.
