Lam Research trades at an unsustainable 57.2 times trailing earnings on peak cyclical optimism. Even assuming 77% earnings growth through FY28, multiple compression to 26 times forward earnings yields a 12-month target of $265.00, or a 19.6% decline.
Key points
- $329.51 share price prices in uninterrupted equipment expansion and commands a rich 57.2 times trailing earnings multiple.
- $10.20 per share in FY28 earnings represents a 77% expansion over FY26, yet still falls short of justifying the current valuation.
- 26 times forward peak earnings yields a 12-month target of $265.00, implying a 19.6% decline as cyclical momentum moderates.
The call
The current price of $329.51 requires Lam to sustain over 40% operating margins and mid-teens annual revenue compounding past $38 billion through FY28. This assumes memory conversions continue without supply digestion, mature-node China spending does not retrench, and wafer fab equipment spending expands unchecked beyond $165 billion annually.

We project instead that equipment demand normalizes by late 2027 as enterprise solid-state drive upgrades mature and fab cleanroom bottlenecks delay installations. Lam's strong technological edge in etch and deposition remains unchallenged, but semiconductor capital equipment remains cyclical. Valuation multiples contract as peak earnings approach, leaving risk skewed to the downside.

Valuation
| Valuation driver | Estimate |
|---|
| FY27E revenue | $33.20 billion |
| FY28E revenue | $37.50 billion |
| FY28E operating margin | 40.3% |
| FY28E diluted EPS | $10.20 |
| Target forward P/E multiple | 26.0 times |
| 12-month price target | $265.00 |
A 26 times forward multiple balances Lam's secular gains in high-aspect-ratio etch and advanced packaging against late-cycle earnings risk. Historical peak equipment earnings rarely trade above 25 times. The resulting asymmetry offers negligible upside against steep downside if industry spending pauses, justifying a Sell rating.
Risks
- Accelerated high-bandwidth memory stacking and panel-level packaging adoption could drive customer tool orders above current shipment capacity.
- Earlier-than-expected digestion in enterprise solid-state drive capacity would cut high-margin upgrade revenue in the Customer Support Business Group.
- Intensified export restrictions on mature-node tools could curtail Chinese foundry shipments, which represented 34% of revenue in fiscal 2026.
What would change my mind
We would turn positive if customer fab construction accelerates to absorb expanded equipment deliveries without triggering memory bit oversupply.
