AOSL CEO Stephen Chang Gifts 100,947 Shares to Family Trust

What Happened

• Stephen Chunping Chang, CEO of ALPHA & OMEGA SEMICONDUCTOR Ltd (AOSL), recorded a gift transaction on August 24, 2026 transferring 100,947 common shares to the "STEPHEN CHUPING CHANG TTEE TRUST" for no consideration (price $0.00; total value $0).
• The reporting person is the trustee of the trust, members of his immediate family are the sole beneficiaries, and he remains the beneficial owner of the securities held by the trust. As a gift, this is not a cash purchase or sale and does not necessarily signal a change in his market view.

Context

• Gifts are common estate-planning or family-transfer actions and do not necessarily reflect buying or selling sentiment. Because Chang remains the beneficial owner and is trustee, economic exposure may be unchanged despite the transfer.
• For retail investors, purchases and open-market sales usually carry clearer signals than intra-family trust transfers like this one.
