On July 22, 2026, Applied Optoelectronics, Inc. President and CEO Lin Chih-Hsiang (Thompson) reported four Form 4 transactions in which a total of 15,640 shares of common stock were surrendered to the issuer at an implied price of $119.26 per share to cover tax-withholding obligations upon the vesting of previously granted restricted stock units from awards dated June 26, 2023, April 29, 2024, April 11, 2025, and February 9, 2026. These dispositions are coded as transaction type “F,” indicating tax withholding rather than open-market sales, and are therefore generally considered routine compensation-related events.
