Alpha & Omega Semiconductor Ltd. reported a recent insider ownership change involving director Joshua C. Chien. The Form 4, filed July 21, 2026, reports a transaction dated July 20, 2026, involving the company’s common shares. The filing states that the reported securities represent common shares subject to restricted share units, or RSUs, granted to Chien for his service on the company’s Board of Directors. The award was made under Alpha & Omega Semiconductor’s 2018 Omnibus Incentive Plan. This indicates the transaction was a director equity-compensation grant rather than an open-market purchase or sale. The RSUs are scheduled to vest on the same dates as the annual grants made to directors at the preceding annual general shareholders meeting. The number of shares vesting on each vesting date will be calculated pro rata based on Chien’s period of service. That vesting structure suggests the award is tied to continued board service and aligned with the company’s regular director compensation program. The filing text provided does not include the exact number of RSUs or common shares covered by the award, the transaction code, a transaction price, or Chien’s beneficial ownership total after the transaction. No sale or disposition is described, and no market price is specified. The report was signed on Chien’s behalf by Yanbing Hong, attorney-in-fact, on July 21, 2026.
