19x P/S and 65x P/E Valuations Heighten Risk for Lam Research
LRCX•Applied Materials trades at a P/S multiple of 19x and a P/E of 64.8x while KLA’s 78x P/E implies a 21.9% revenue CAGR over six years. These peak margins, supply-chain strains and flawless execution demands suggest similar valuation risks for Lam Research.
1. Valuation Peaks in Chip Equipment
Applied Materials now trades at 19x price-to-sales and 64.8x P/E, while KLA’s 78x P/E requires nearly 22% annual revenue growth over six years. These stretched multiples reflect market confidence but leave no margin for underperformance in a competitive AI equipment market.
2. Margin Sustainability Concerns
Applied Materials just reported its highest gross margin in over 25 years and a net margin of 29.3%, but such peaks often normalize as product cycles mature or competition intensifies. KLA’s last-twelve-month net margin of 35.7% also sits near its decade high, highlighting industrywide vulnerability to margin compression.
3. Supply-Chain Bottlenecks and Execution Risk
Both companies warn that the semiconductor equipment business could grow over 30% this year, yet supply-chain constraints for complex machine components pose a critical execution hurdle. Any delays or part shortages could cap deliveries and erode growth forecasts baked into current valuations.
4. Implications for Lam Research
Lam Research faces parallel pressures as investors price in flawless AI-driven demand. To justify similar multiples, LRCX must sustain peak margins and overcome the same sourcing and logistical challenges, making even minor execution missteps a catalyst for a sharp re-rating.
