Context

• These were conversions of RSUs (derivative-to-share conversions), not an open-market purchase. The disposals reported were to satisfy tax withholding (common and routine), not indicative of an outright sale for investment purposes.
• Transaction codes: M = exercise/conversion of derivative (RSU conversion here); F = payment of tax liability via share withholding/sale. No 10% owner, 10b5-1 plan, or gift was indicated.
