MP Materials Corp. reported an insider ownership change by Connie K. Duckworth on June 30, 2026, involving the company’s common stock. The filing describes an award of deferred stock units, or DSUs, granted in connection with Duckworth’s election to defer cash retainers. Each DSU represents the right to receive one share of MP Materials common stock. The DSUs were fully vested at the time of grant, meaning no additional service-based vesting condition applies after the award date. The filing does not state a cash purchase price, indicating the reported securities were tied to deferred compensation rather than an open-market purchase or sale. The DSUs will be settled upon the earliest of three events: June 15 following the end of the fifth calendar year after the year in which the deferred cash retainers were earned; certain changes in control of MP Materials; or Duckworth’s separation from service. This structure is typical of director or insider deferred compensation arrangements, allowing cash compensation to be converted into equity-linked units payable later in shares. The filing text provided does not include the number of DSUs awarded, the transaction code, or Duckworth’s beneficial ownership total after the transaction. It does, however, make clear that the reported action was an insider acquisition of equity-linked compensation rather than a disposition of shares. The form was signed on Duckworth’s behalf by Elliot D. Hoops as attorney-in-fact.
