What Happened Luis A. Muller, President & CEO of Cohu, had 8,851 shares withheld on March 12, 2026 to satisfy tax obligations upon vesting of restricted stock units (RSUs). The withheld shares were treated as a disposition with $0 proceeds (transaction code F — tax withholding).

Key Details

• Transaction date: 2026-03-12; filing date: 2026-03-13 (appears timely).
• Shares withheld/disposed: 8,851; price reported: $0.00; total proceeds: $0.
• Footnote F1: These shares were automatically withheld upon RSU vesting to cover taxes; transaction exempt under Rule 16b-3.
• Footnote F2: The filing also notes 598,819 RSUs (excluding shares expected to be withheld for taxes) that will convert one-for-one into Cohu common stock upon future vesting/achievement of performance goals.

Context This was a routine tax-withholding event tied to RSU vesting (not an open-market sale or purchase). Withholdings to cover tax liabilities are common and do not necessarily signal the insider's view of the stock.
