Key Details

  • Transaction date: 2026-05-08; SEC filing date: 2026-05-11 (timely filed).
  • Price: $71.82 per share (price translated from NT$2,257.1777 at NT$31.429 = US$1).
  • Shares acquired: 160; total value: $11,491.
  • Shares owned after transaction: not reported in this Form 4.
  • Footnotes: purchase executed by the ESPP administrator on filer’s behalf (F1, F3); USD price is a translation from New Taiwan dollars (F2); some shares were acquired by a trust funded by the issuer’s LTI Bonus Plan over which the filer has investment control (F4).

Context
This was a company plan purchase (ESPP/trust-funded) made under pre-set plan terms — common for executives and generally viewed as routine compensation/benefit activity rather than a direct market-timing signal. Purchases under ESPPs can indicate ongoing company participation but do not, by themselves, prove insider sentiment about near-term stock moves.
