Lin Chih-Hsiang (Thompson) 4

What Happened

• Chih‑Hsiang Lin, President, CEO and Director of Applied Optoelectronics, reported dispositions on June 12, 2026. He had 86,655 shares withheld to satisfy tax withholding related to an option exercise (86,655 @ $172.78, ~$14.97M) and sold 59,000 shares in open-market transactions (weighted avg $166.53, ~$9.83M). Combined disposals total 145,655 shares for about $24.8 million.
• These were disposals (sales/withholding), not purchases — a common way insiders cover tax obligations after exercising options and to liquidate holdings.

Key Details

• Transaction dates & prices: June 12, 2026. Tax-withheld shares: 86,655 @ $172.78 ($14,972,251). Open-market sale: 59,000 @ weighted average $166.53 ($9,825,270). Footnote indicates open-market sale prices ranged $163.78–$171.80 per share.
• Shares owned after transaction: not specified in the filing.
• Notable footnotes:
  • F1: The 86,655 shares were withheld to satisfy tax withholding obligations.
  • F2: The 59,000-share sale occurred in multiple transactions; the filing reports a weighted average price and will provide per-transaction details upon request.
  • F3: Some securities are indirectly held in an irrevocable Family Trust via an LLC for the benefit of heirs; the reporting person disclaims beneficial ownership except to the extent of voting power.
• Filing timing: Form 4 was filed June 16, 2026 for trades on June 12, 2026 (filed four days after the trades). Form 4s are generally due within two business days of a transaction, so this filing was later than the typical 2-business-day window.

Context

• The withheld shares indicate a cashless element of an option exercise (shares withheld to cover taxes) rather than an additional cash purchase by the insider.
• Open-market sales can be routine liquidity events and do not, by themselves, indicate the insider’s view on company prospects.
