Lam Research Packaging Growth of 50% Adds AI Demand Vector, but China Risk Remains

What happened

Lam Research has highlighted that its advanced packaging business is seeing 50% growth, driven by AI chip demand that requires more etch and deposition equipment. This new catalyst aligns with the company's raised CY2026 WFE view to ~$140B and supports the bull case of sustained AI-led spending. However, the latest 10-Q reveals that China still accounts for 34% of revenue and management warns that export licenses could materially and adversely affect sales. Meanwhile, non-leading-edge equipment spending is declining, creating a bifurcated cycle that pressures margins if services don't offset. The stock's high valuation (P/E 48x) leaves no margin of safety, making the packaging growth a positive but insufficient counterweight to policy and mix risks.

Implication

Investors should view the packaging growth as a positive incremental development that reinforces the AI-driven demand thesis, but it does not alter the fundamental risk from China export controls, which remain the dominant swing factor. The master report's WAIT rating hinges on whether China revenue falls below 25% and gross margins hold above 50% in the next quarter. The packaging growth could help diversify revenue away from China over time, but the near-term China concentration is 34% and management's language on licenses is unusually severe. Valuation at 48x P/E already prices in significant AI growth, leaving no room for disappointment if license delays or mixed non-leading-edge spending weigh on results. Until the June 2026 quarter confirms a cleaner growth mix and margin resilience, the risk/reward is not attractive enough to initiate or add positions.

Thesis delta

The thesis now includes an incremental bullish driver from advanced packaging demand, which could support a higher bull case value. However, this does not change the core bear risk from China export controls and the stock's rich valuation. The overall rating remains WAIT, with the packaging catalyst potentially accelerating the timeline for the 'Increases If' condition if it helps reduce China mix.
