Did the COHU Form 4 show Klaus Ilgenfritz selling shares on the market?

No open-market sale was disclosed. The 1,098 COHU shares were automatically withheld to satisfy tax obligations tied to Restricted Stock Unit vesting, a non-market transaction exempt under Rule 16(b)-3, rather than a discretionary sale for investment purposes.

What happened to the 7,425 COHU Performance Stock Units reported as a transaction?

The 7,425 Performance Stock Units were forfeited because specified performance goals were not fully achieved. These units had been previously reported and are now removed from his equity awards, representing an adjustment based on performance rather than a market trade.
