Lam Research Stock Price Drops 2.4%: Why LRCX Slid Even as AI Chip Demand Held Up

NEW YORK, March 22, 2026, 11:55 AM EDT

Lam Research (LRCX) fell 2.4% to $228.36 on Friday, as tech stocks slumped and the Nasdaq Composite dropped 2.01%. Oil was up and concerns about interest rates intensified.

This shift carries weight: Lam Research is widely seen as a barometer for wafer-fab equipment, those critical chipmaking machines underpinning the latest semiconductor advances. Back in January, Reuters noted Lam projected March-quarter revenue around $5.7 billion—topping what Wall Street had penciled in. CEO Tim Archer, for his part, pointed to “ramping execution velocity,” with AI-driven demand steering clients toward ever-smaller, increasingly complex chip designs. Reuters

Peers diverged. ASML slipped 3.5% on Friday. KLA edged down 0.8%. Applied Materials barely budged. That put Lam’s drop right in the middle of the semiconductor-equipment group.

Just a few weeks ago, things looked more solid for the sector. In February, Reuters noted Applied Materials had raised its forecast, citing AI-fueled demand and a tighter memory supply. Lam and KLA stocks jumped on the news. Morningstar’s William Kerwin called for a “massive” surge in wafer-fab equipment—chipmaking gear, essentially. Reuters

But Lam isn’t immune. According to an SEC filing, China made up 35% of revenue in the December quarter. Taiwan and Korea each contributed 20%. The company pointed to trade rules, export restrictions, tariffs, and geopolitical friction as possible threats to both sales and profit.

The wider downturn soon swept in. Global stocks tumbled, Treasury yields spiked, and oil surged to its priciest close since July 2022, with the Middle East war rattling nerves. Investors, spooked, began to factor in possible Fed hikes instead of cuts, according to Reuters.

Back in January, Lam projected March-quarter revenue at roughly $5.7 billion, give or take $300 million, alongside adjusted earnings pegged at $1.35 per share. With Friday’s slide, those figures probably set the next line in the sand for LRCX watchers.
