Lam Research: Record Operating Margin Strengthens the AI Equipment Thesis
RATING: STRONG BUY (maintained) | TARGET: $400 | PRICE: $318.84 as of October 9, 2026 | UPSIDE: 25.5%
Summary
Fiscal Q4 revenue rose 30% year over year to $6.72 Bn and adjusted EPS reached $1.82, beating consensus by about $57 Mn and $0.13, respectively.
The thesis strengthened: non-GAAP operating margin reached 38.4%, CY26 WFE moved to the low-$150 Bn range, and September-quarter revenue guidance jumped to $8.10 Bn.
My base case uses $41.30 Bn of fiscal 2028 revenue and $11.76 of EPS. A 39x future P/E discounted one year at 14.33% gives a present value near $401, rounded to $400.
I maintain a Strong Buy because the target offers 25.5% upside, although a high multiple, customer concentration, and export controls leave a wide bear case.
