Insights

CFO executed a series of open-market share sales but retains a substantial equity stake.

Ultra Clean Holdings CFO Sheri Savage reported selling 15,766 shares of common stock in 17 open-market transactions on June 4, 2026. All trades involve non-derivative common shares, with no option exercises or grants disclosed in this filing.

Footnotes show weighted-average sale prices across several ranges, from $85.76 up to $91.95 per share, indicating execution throughout the trading day rather than a single block. This pattern is consistent with liquidity management rather than a structural change in compensation.

Following the sales, Savage directly owns 66,080 shares, so she maintains a meaningful equity position. The filing does not reference any Rule 10b5-1 trading plan, and there is no information here about company fundamentals; the event is best viewed as a routine insider disposition.

"aff_10b5_one is the filing's document-level Rule 10b5-1 checkbox"
Rule 10b5-1 is a regulation that allows company insiders to buy or sell their shares at predetermined times, even if they have access to non-public information. It acts like setting a schedule in advance for transactions, helping prevent accusations of unfair trading. This rule provides a way for insiders to plan trades transparently, giving investors confidence that these transactions are not based on hidden information.
