Context

• These are derivative/award transactions (PSUs). PSUs were "earned" by the Compensation Committee for fiscal performance and generally remain subject to future vesting and conversion dates (per footnotes). A portion was converted/vested solely to cover tax withholding (a routine, non‑market-sale action).
• Transaction codes: A = award/grant; M = exercise/conversion of a derivative; F = shares disposed to satisfy tax liability. This is not an open-market sale or intentional liquidity event beyond standard tax withholding.
