Lam's Foundry Strength Highlights Valuation and Risk Concerns Amid AI Hype

What happened

A Zacks article projects strong Q3 systems sales for Lam Research driven by foundry demand and AI chip trends. This aligns with DeepValue's report, which shows Lam's revenue mix is 60% foundry versus 34% memory, contradicting the pure AI-memory narrative. DeepValue notes that export licensing risks and conversion delays are critical, with China accounting for 39% of revenue. At a P/E of 43.3, the stock prices in a sustained upcycle, but foundry-led growth may not support the premium without memory mix improvement. Investors should interpret the positive news cautiously, adhering to DeepValue's WAIT rating until clearer signals on China stability and conversion timing emerge.

Implication

The article's emphasis on foundry demand confirms DeepValue's finding that Lam's earnings are primarily foundry-driven, not memory-led, which tempers the AI beneficiary story. With a P/E of 43.3, any revenue miss or China issue could trigger significant downside, given the stock's elevated multiples. Monitoring the next quarter's revenue around $5.70B and China share above 33% is crucial to avoid thesis breakers. The crowded AI narrative increases volatility, making Lam sensitive to negative news on shipment delays or policy changes. Therefore, despite optimistic sales projections, a WAIT strategy is advisable until evidence of stable China revenue or a more attractive entry price materializes.

Thesis delta

The new article does not shift DeepValue's thesis; it reinforces the existing view that Lam's growth is foundry-centric and highlights persistent risks. No fundamental change is indicated, but the continued market optimism may delay necessary valuation corrections.
