For Lam Research, the new restrictions hit its largest market

• China made up 43% of Lam Research’s total revenue in the first quarter of fiscal 2026, making it the company’s largest market. The new US order lands on that business directly 1.
• Lam estimates earlier curbs could cut its China sales by US$600 million in 2026, and this latest move adds to that strain 1.
• Lam Research shares dropped 3.1% on Tuesday after the Hua Hong restrictions, even with broader trade tensions already weighing on the sector 2.

US export policy now singles out facilities, including fabs labeled as mature-node sites

• The US uses “is-informed” letters to block shipments to named chip plants, including Hua Hong facilities, when officials believe they could help produce China’s most advanced chips 2.
• That push is speeding up China’s self-sufficiency drive and encouraging state-backed tie-ups, including Hua Hong’s plan to buy 97.5% of Shanghai Huali Microelectronics, a chip manufacturing company 3.
• The policy reaches beyond leading-edge sites. It blocks shipments to a fab, or semiconductor manufacturing plant, that Huali’s website says uses 28/22-nanometer technology, over concerns it may support advanced chip production 2.
• That expands uncertainty for a wider range of semiconductor equipment and materials suppliers.
