Morris John Christopher 4

What Happened
Morris John Christopher, EVP & CTO of Seagate Technology Holdings plc (STX), had RSUs convert to common shares on March 9, 2026. Two derivative conversions of 499 and 631 shares (total 1,130 shares) occurred at a $0.00 exercise price (RSU conversion). To cover tax withholding, 228 shares ($85,347) and 288 shares ($107,807) were surrendered at $374.33 per share, for a total withholding value of $193,154. Net shares retained by the insider after withholding were 614 shares (1,130 vested − 516 withheld). These transactions reflect routine RSU vesting and tax withholding rather than an open-market sale.

Context

• This was a vesting/net-settlement event (RSUs converting to shares with some shares withheld to cover taxes), common for executive compensation.
• Code explanations: M = exercise/conversion of a derivative security (here RSUs); F = payment of exercise price or tax liability (share withholding).
• Such tax-withholding disposals are routine and do not necessarily signal the insider’s view on the stock.
