Lam Research Q3 2026: A Constrained $200 Billion, and NAND Gets Its Own Trade Ratio

Ben Bajarin · October 22, 2026

Creative Strategies earnings read | October 22, 2026 | Lam Research September 2026 quarter results and conference call, October 21, 2026 Lam told investors that cleanroom space and component supply will set the pace of 2027 equipment spending while demand runs above it, and it gave NAND its first new reason in years to need more wafers for every bit it ships. Operating view: Lam's preliminary view of 2027 wafer fab equipment, more than $200 billion on a mid-$150 billion 2026, sits above our WFE Base case ($187 billion) and just under our High case ($208 billion), and management described it as a constrained number with real demand above it. That is the second equipment maker in two weeks to land on our High case for 2027, after ASML's roughly 85-system EUV plan.
