On September 14, Advanced fell 5.26% in pre-market trading, trading at $270.41/share, with turnover of $7,220.4.

On the news front, the semiconductor equipment sector came under broad-based selling pressure as escalating US-China trade friction combined with tightened semiconductor export controls weighed heavily on the industry. Major peers across the sector posted significant declines, with Applied Materials down 4.71%, Lam Research down 4.86%, KLA Corporation down 4.11%, ASML down 4.02%, and Teradyne down 5.19%, reflecting pronounced sector-wide linkage effects.

As a supplier of precision power conversion solutions for semiconductor equipment markets, Advanced was dragged lower by the systemic downturn across the sector. The company's products, including plasma power systems, RF power supplies, and electrostatic clamping power modules, are integral to advanced chip fabrication processes such as etch and deposition. Meanwhile, recent regulatory developments have further expanded export restrictions on advanced semiconductor equipment and components, intensifying uncertainty for equipment-related suppliers.
