On July 29, Ultra Clean fell 8.03% in regular trading, trading at $71.275/share, with turnover of approximately $50.44 million.

On the news front, the semiconductor equipment sector continued its multi-day selloff, with industry peers broadly declining: KLA-Tencor down 8.58%, Applied Materials down 6.15%, Lam Research down 5.24%, and ASML down 2.44%. Ultra Clean had already recorded approximately 8% or greater declines on July 24, 27, and 28, with cumulative pullback becoming significant.

The stock faces dual headwinds from systematic sector selling pressure and pre-earnings uncertainty. The company is scheduled to report quarterly results on August 3 after market close, with consensus expectations calling for revenue of approximately $587 million, representing 17.11% year-over-year growth, and adjusted EPS of $0.53. However, institutional views remain cautious. The combination of broad sector weakness and upcoming earnings risk has driven Ultra Clean to consistently underperform its peers during this correction.
