• Filing date: Form 4 filed 2026-07-09 (appears to be timely; Form 4 is normally due within two business days).

• Relevant footnotes from the filing:
  • F1/F3: Shares were purchased by the ESPP administrator on behalf of the filer and are held under the ESPP.
  • F2: The reported US dollar price was translated from an average purchase price of NT$2,462.6361 using an exchange rate of NT$32.143 = US$1.
  • F4 appears in the filing set but does not appear to apply to this specific ESPP purchase.

Context

• This was a purchase (often viewed as a positive signal relative to sales), but it was a small, routine ESPP buy that may reflect normal employee-plan activity rather than a personal market-timing decision.
• ESPP purchases are typically made under pre-set plan terms (contribution schedule and purchase dates), so they are less informative about immediate insider sentiment than discretionary open-market buys.
