Sold-out demand confirms strong cycle but does not resolve valuation and China risks

What happened

Lam Research management publicly stated semiconductor equipment demand remains strong with customers seeking tools sooner than the company can provide, prioritizing customer execution and capacity readiness. This aligns with the guided revenue ramp to $6.60B ± $0.40B for the June 2026 quarter and supports the market's AI buildout narrative. However, latest filings show growth concentrated in DRAM with China representing 34-37% of revenue, exposing outsized risk to export licensing and localization. At a trailing P/E above 81 and EV/EBITDA above 85, the stock already prices sustained upcycle conditions with little room for error. The new commentary is positive for demand visibility but does not materially alter the base, bear, or bull scenarios from the WAIT-rated master report.

Implication

The sold-out demand signal supports the thesis that AI-led WFE spending remains robust, but it does not resolve the structural China exposure or narrow DRAM mix that underpin the bear case. At current prices, the market is already assuming sustained ~$6.6B+ quarterly revenue and no China-driven reset, leaving limited upside to a base case of $440. A more attractive entry near $360 would offer better compensation for the 25% probability of a China or cycle-driven drawdown. Investors should monitor the upcoming June quarter print and any change in China revenue share or licensing language before adding exposure. The WAIT rating remains appropriate until clearer evidence of mix broadening or a pullback in price.

Thesis delta

The new commentary moderately strengthens near-term demand conviction but does not change the valuation or China risk calculus; the WAIT rating and $360 attractive entry stand.
