Lam Research (LRCX) slips after report China tightens “50% domestic tools” push
Lam Research shares fell 1.2% to $173.78 in after-hours trading Tuesday after Reuters reported China now requires chipmakers to source at least 50% of equipment domestically for new capacity approvals. Applied Materials and KLA also declined, while ASML rose. The policy could pressure foreign suppliers like Lam, which derives about 93% of revenue from non-U.S. sales. Investors are watching for details on enforcement and possible waivers.
