This transaction is part of a pre-arranged 10b5-1 trading plan, meaning it was scheduled rather than discretionary.

At the current price of $83.93, the stock has declined -11.6% from its 52-week high of $94.95. Across Savage's prior five same-ticker sales at UCTT, her 90-day post-sale returns have consistently been negative, ranging from -25.6% to -30.2%, establishing a pattern of selling before subsequent declines at this specific ticker.

CFO Sheri Savage sold 15,766 shares for $1,410,556.23 via 10b5-1 plan on 2026-06-04, reducing stake 23.7%.

Sheri Savage, CFO of Ultra Clean Holdings, executed 17 separate sales totaling 15,766 shares for $1,410,556.23 under a pre-arranged 10b5-1 trading plan on 2026-06-04, reducing her holdings from 66,476 to 50,710 shares. As a scheduled transaction, this sale reflects plan mechanics rather than discretionary timing decisions. The company reported a net loss of $-17,900,000.00 in its most recent quarter and negative full-year net income, while the stock trades at $83.93, down 11.6% from its 52-week high of $94.95. In her prior five trades at UCTT, Savage's sales were followed by 90-day returns of -36.1%, -26.9%, -30.2%, -25.7%, -25.6%, and -26.0%, while the blended transaction price of $89.47 for this sale sits above the current price, creating an immediate underwater position for shares sold at the higher end of the distribution ($91.76–$91.63).

Chief Accounting Officer sells 16,988 shares ($1.5M) on single day via 22 transactions under 10b5-1 plan

Brian E Harding, Chief Accounting Officer at Ultra Clean Holdings, executed 22 separate sales totaling 16,988 shares for $1,519,891.98 on 2026-06-04 at prices ranging from $85.86 to $91.65, reducing his holdings by 37.7% from 45,043 to 28,055 shares. This transaction was scheduled under a pre-arranged 10b5-1 trading plan, meaning it was automatic and not a discretionary decision. The company is currently unprofitable with net income of $-17,900,000.00 on revenue of $533,700,000.00, and has experienced annual revenue decline of -2.1%, though the stock has appreciated 49.2% over the past 90 days from its earlier 52-week lows. The mechanical nature of the sale under a 10b5-1 plan removes any timing signal, but investors should note the context: a significant reduction in CAO holdings during a period of corporate unprofitability.

UCTT President divests roughly one-tenth of stake while stock trades near 52-week highs amid revenue and earnings pressure.

Christopher Cook, President of Ultra Clean Holdings' Products Division, sold approximately one-tenth of his shareholding in two transactions totaling nearly $849,000 as the stock trades near its 52-week high. This sale contrasts sharply with his prior purchase just over a year ago at substantially lower valuations—a trade whose outcome remains too recent to assess. The timing is notable: Cook is executing this sale into a stock that has rallied strongly over recent months, which could suggest profit-taking or a shift in conviction as the company faces deteriorating fundamentals. Ultra Clean is currently unprofitable with declining revenue, creating an environment where an insider officer reducing exposure at elevated prices warrants closer attention. Without visibility into Cook's broader portfolio strategy or near-term company catalysts, the sale alone is routine, but the juxtaposition of near-term buying followed by meaningful selling during a price spike suggests this insider's conviction may not be as durable as the purchase suggested.

Director Clarence Granger sells ~$2.26M in UCTT shares across four tranches on single day.

Director Clarence Granger executed a sizable liquidation of approximately $2.26 million worth of Ultra Clean Holdings stock in four transactions on a single day, reducing his holdings by nearly 30 percent total. This is a meaningful departure from holding, though the company's fundamentals provide important context: Ultra Clean is currently unprofitable with declining revenues, making the timing of a director's exit notable. Notably, the stock had rallied significantly over the prior three months before this sale, which often prompts insiders to take chips off the table after momentum gains. Granger's directorship gives him material visibility into operations, but the sale itself does not necessarily signal crisis — rather, it reflects a deliberate portfolio management decision by a board member who may be rebalancing or locking in recent gains rather than expressing conviction about deteriorating business prospects.

President of Products Division sells $896K in stock on same day as three stock-comp withholdings; company unprofitable with declining revenue.

Cook Christopher S, President of Ultra Clean Holdings' Products Division, executed a sale of approximately $896K in stock alongside three separate tax withholding transactions on the same day—a common pattern when executives receive restricted stock units and elect cash settlement for tax obligations. The cumulative effect disposed of roughly 17.6% of his holdings. The timing coincides with the stock trading near the middle of its 52-week range, having recovered significantly from its lows but still short of its 52-week high. Cook has only one prior open-market trade at this ticker, a purchase made too recently to measure outcomes, so there is no track record of successful timing at this company. Notably, Ultra Clean is currently unprofitable with declining annual revenue, which provides context for why an executive might scale back ownership—fundamentals are pressured rather than bullish. The sale itself is substantial enough to exceed the executive threshold, but the transaction breakdown shows it represents forced stock-comp withholding alongside a discretionary sale rather than a single coordinated exit.

UCTT President of Products buys 4,100 shares at $25.30; 4 other insiders also bought within 14 days in cluster pattern.

Christopher S Cook, President of the Products Division, purchased 4,100 shares at $25.30 on 2025-03-07 for a total value of $103,709.50, marking an initial position entry. This transaction occurs as part of a broader cluster buy pattern, with 4 other insiders also purchasing shares within the past 14 days. The stock is currently trading at $35.45, representing a price 30.2% above the transaction price, though the stock remains -36.9% from its 52-week high of $56.18. Ultra Clean Holdings reported net income of $-2.3M in the latest quarter despite strong annual revenue growth of +20.9%, indicating operational challenges persist despite topline expansion. The coordinated buying activity across multiple insiders warrants attention to whether such acquisitions reflect internal confidence or represent a programmatic response to market conditions.

Chief Accounting Officer buys 4,000 shares at $24.00; stock at $35.45 (-36.9% from 52-week high); 4 other insiders also bought in past 14 days

Brian E. Harding, Chief Accounting Officer, purchased 4,000 shares at $24.00, increasing his holdings to 38,212 shares (+11.7%). The transaction occurs as UCTT trades 36.9% below its 52-week high and down 9.8% over 90 days. Most notably, this buy is part of a cluster pattern with 4 other insiders also purchasing within the past 14 days, suggesting coordinated board-level or executive conviction during a period of price weakness. However, fundamental headwinds are present: the company reported net income of -$2.3M in the latest quarter despite 20.9% annual revenue growth, and the P/E of 27.48 remains elevated against that recent loss. The cluster buying activity warrants tracking whether it reflects confidence in a turnaround or is driven by other factors such as equity compensation timing.

Director Maddock buys 10,000 UCTT shares at $24.29; holdings surge 1000.0% to 11.0K. Cluster pattern with 4 other insiders in 14 days.

Ernest Maddock, a director of Ultra Clean Holdings, purchased 10,000 shares at $24.29 on 2025-03-07, expanding his holdings from 1,000 to 11,000 shares (+1000.0% increase). This transaction occurs amid a coordinated buying pattern: 4 other insiders have also purchased within the past 14 days. The director's purchase was made at a price substantially below the current market level of $35.45, and notably below the 52-week high of $56.18 (current price is -36.9% from that high). Across his cross-ticker track record, Maddock has generated a 100.00% win rate on 90-day holdings (4 prior buys, avg 90d return +16.3%), suggesting a consistent ability to time purchases favorably, though this prior success is not specific to Ultra Clean.

Director Granger buys 1,000 shares at $25.15; joins cluster of 4 other insiders buying in past 14 days

Clarence L. Granger, a Director, purchased 1,000 shares at $25.15 on 2025-03-07, establishing an initial position in UCTT. This purchase is part of a cluster pattern, with 4 other insiders also buying within the past 14 days, suggesting coordinated insider interest at this price level. While the current price of $35.45 sits 36.9% below the 52-week high and the stock has declined 9.8% over 90 days, the company maintains revenue of $540,400,000.00 and annual revenue growth of +20.9%, despite a recent quarterly net loss of $-2,300,000.00. The presence of multiple concurrent insider purchases in a growth-stage company signals management's assessment of intrinsic value amid near-term volatility.
