Monolithic Power Systems (MPWR) EVP Maurice Sciammas Receives Award
What Happened
- Maurice Sciammas, EVP, WW Sales & Marketing at Monolithic Power Systems (MPWR), was awarded 57,170 shares on February 3, 2026 when performance-based restricted stock units (PSUs) vested. The Form 4 lists the acquisition price as $0.00 because these shares were issued on settlement of a prior PSU grant rather than an open-market purchase.
Key Details
- Transaction date: February 3, 2026 (Form filed February 5, 2026).
- Transaction type: A = Award/Grant (vesting/settlement of PSUs); reported acquisition price $0.00.
- Shares awarded/received: 57,170 shares (subject to tax withholdings per footnote).
- Footnote: PSUs were originally granted Feb 7, 2023; the Compensation Committee certified performance achievement and all shares vested and were released on Feb 3, 2026. Shares are subject to tax withholding.
- Shares owned after the transaction: not specified in the filing.
- Timeliness: Filing appears timely (period ending 2026-02-03; filed 2026-02-05).
Context
- These were performance-based RSUs that vested after a three-year performance period; the reported $0.00 acquisition reflects issuance on vesting rather than a cash purchase. Awards and vesting are routine forms of executive compensation and do not by themselves indicate a buy or sell decision. Tax withholding may have reduced the net shares delivered to the insider.
