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 MADDOCK ERNEST E purchased 8,000 shares at $7.79 amid -52.1% decline from 52-week high, stock down 44.1% in 30 days.

Director Maddock purchased 8,000 shares of OUST at $7.79 on 2024-08-16, increasing his holdings by 13.1% during a period of significant price deterioration: the stock is down 52.1% from its 52-week high of $16.39 and has declined 44.1% over the past 30 days. His cross-ticker track record shows a 66.67% 90-day win rate, but same-ticker history at OUST is mixed—a November 2023 buy returned +29.6% in 30 days and breakeven at 90 days, while an August 2023 buy returned -22.8% in 30 days and -10.5% at 90 days. The company remains unprofitable (net income of $-23.9M on revenue of $27.0M in the latest quarter) despite 103.0% annual revenue growth, raising questions about path to profitability. The purchase during a steep drawdown warrants tracking whether this reflects conviction in a recovery or is inconsistent with prior trade execution at this ticker.
