What Happened Klaus Ilgenfritz, Senior Vice President and Chief Product Officer of Cohu Inc. (COHU), had 998 restricted stock units (RSU) shares automatically withheld upon vesting to satisfy tax obligations on 2026-03-12. The filing reports these shares as a disposition with an exercise/price of $0.00 and no cash proceeds. The withholding transaction is reported as exempt under Rule 16b-3 (see footnote F1).

Key Details

  • Transaction date: 2026-03-12 (filed 2026-03-13).
  • Type: Tax withholding of RSUs (reported as disposition code F).
  • Shares withheld: 998; reported price/exercise: $0.00; reported value: $0.
  • Shares owned after transaction: not specified in the provided filing.
  • Footnotes: F1 confirms automatic withholding to cover taxes; F2 notes 82,630 RSUs remain scheduled to convert one-for-one into common stock upon future vesting (excluding future withholding).
  • Filing timeliness: Report appears timely (transaction 3/12, filed 3/13).

Context Withholding shares to cover taxes is a routine administrative action when RSUs vest and does not represent an open-market sale or a deliberate buy/sell decision by the insider. Such withholdings reduce the net shares the insider receives and are commonly exempt from short-swing profit rules under Rule 16b-3.
