AI Semiconductor Material Beneficiaries Lose Over $1 Billion in Market Value in a Day

Entegris Inc. (NASDAQ: ENTG), a U.S.-based advanced materials and process solutions provider for semiconductor manufacturing, tumbled 5.79% in New York trading on July 7, closing at $136.77. The drop wiped out about $1.1 billion (approximately KRW 1.5 trillion) in market capitalization, reducing its total market value to roughly $20.8 billion (about KRW 29 trillion). Trading volume reached 3.21 million shares, slightly above the one-year average of around 2.83 million.

In the first quarter of fiscal 2026, Entegris posted revenues of about $812 million (roughly KRW 1.1 trillion), marking year-over-year growth. For the second quarter, the company has issued revenue guidance in the range of $815 million to $845 million.

Earlier in 2024, Entegris secured subsidy funding under the U.S. CHIPS Act. Through the integration of CMC Materials, acquired in 2022, it has expanded its portfolio of advanced-process CMP slurries and high-purity materials, positioning itself to benefit from AI semiconductor investments.

Founded in 1966 and headquartered in Billerica, Massachusetts, Entegris employs approximately 7,700–8,000 people globally across its manufacturing and R&D facilities. For fiscal 2025, the company generated about $3.2 billion in revenue (around KRW 4.5 trillion).
