Context

• Transaction codes: M = exercise/conversion of derivative (options), S = open‑market sale. This filing shows an option exercise followed by sales — functionally similar to a cashless exercise/sell strategy.
• Sales under a pre‑arranged 10b5‑1 plan generally indicate scheduled disposition, reducing the implication that sales reflect immediate insider sentiment.
• All figures above are gross proceeds and do not account for taxes, fees, or other withholdings unless separately disclosed.
