Monolithic Power (MPWR) Director Jeff Zhou Receives RSU Award

What Happened

  • Jeff Zhou (Director) received a grant of 189 restricted stock units (RSUs) on February 3, 2026. The acquisition price is reported as $0.00 (award/grant). The RSUs do not represent an immediate cash transaction and will convert to shares if/when they vest.
  • This is a routine director compensation grant rather than a market purchase or sale.

Key Details

  • Transaction date and price: 2026-02-03; 189 RSUs @ $0.00.
  • Filing date: 2026-02-05 (filed within the normal 2-business-day Form 4 reporting window).
  • Shares owned after transaction: Not specified in the filing.
  • Footnote: The board approved annual RSU grants to each independent director; these RSUs vest one year after the grant date, subject to continued service with the company (per footnote F1).
  • No 10b5-1 plan, tax-withholding sale, or option exercise noted.

Context

  • RSU awards to independent directors are common as non-cash compensation and do not indicate an immediate buy/sell signal. Vesting is time-based and contingent on continued service, so these shares will only become owned stock if Mr. Zhou remains on the board for the vesting period.
