On July 28, Entegris fell 5.04% in regular trading, trading at $120.515/share, with turnover of $41.07 million. The decline was driven by a broad sell-off across the global semiconductor equipment sector after the Korean KOSPI index plunged over 8% intraday, triggering a circuit breaker mechanism.

Major Korean chipmakers SK Hynix and Samsung Electronics dropped over 13% and 12% respectively, sending panic rippling through the global semiconductor supply chain. Within the Semiconductor Equipment sector, Amkor Technology fell 23.37%, Lam Research declined 8.22%, Applied Materials dropped 7.26%, KLA-Tencor lost 6.44%, and ASML slid 4.97%. The systemic selling pressure was compounded by pre-earnings caution, as Entegris is scheduled to report quarterly results on August 4, with consensus estimates calling for revenue of $835 million and adjusted EPS of $0.82. The proximity of the earnings window further intensified investor risk-aversion, weighing on the stock alongside sector-wide weakness.
