Lam Research Corporation LRCX

Lam trades near 69 times trailing earnings — roughly three times its ten-year median of about 20 and at the very top of its decade range — because the market is pricing an AI-driven memory super-cycle as permanent. The March 2026 quarter was a record: $5.84 billion in revenue (+24% year over year), a 35.0% operating margin and $1.45 of EPS. The multiple assumes that level of demand and profitability holds rather than mean-reverting, which is a strong claim for a business whose spending has always moved in cycles.

Near $367 the stock already trades above its average analyst price target of about $334, so even the desks that spent June raising estimates see, on average, less upside than the price implies. Conservative intrinsic-value models — crediting a forward EPS growth of 20–25%, well above Lam's ~8% ten-year pace — land between roughly $86 and $218 a share. That doesn't make the price wrong, but it shows how much future the multiple has already borrowed: good news is now the expectation, not the surprise.

At 69 times earnings the price discounts four things going right at once: the AI memory and HBM build-out keeps wafer-fab spending climbing, Lam's record ~35% operating and ~31% net margins hold, its etch-and-deposition franchise keeps gaining content as chips go 3D, and China — about a third of revenue — stays resilient under tightening US rules. In short, it discounts peak demand and peak margins and a benign regulatory backdrop simultaneously, leaving little margin for a single disappointment.

China is Lam's largest market at about 34% of revenue — roughly $2 billion last quarter and about $6.2 billion in fiscal 2025 — down from a ~42% peak in 2024 and guided lower toward ~30%. The risk is regulatory: late-2025 US rules revoked the Validated End-User status for foreign-owned fabs in China effective December 31, 2025, and will license existing fabs but not expansions. Applied Materials, similarly exposed, quantified the hit at roughly $600 million of 2026 revenue, a useful read-across for Lam.

Wafer-fab equipment is one of the most cyclical markets in technology, and Lam is the most memory-levered of the big three, more tied to NAND and DRAM capital spending than Applied Materials or KLA. Memory budgets swing hard: today's record ~35% operating margin reflects a cycle peak, not a steady state. As recently as the 2022–2023 downturn, semicap revenue and margins compressed and Lam's multiple fell toward the single digits — the ~8x low still in its ten-year range — which is why buying record earnings at 69x carries real cycle risk.

The consensus 12-month target is about $334 across roughly 34 analysts, with a range from $220 to a Street-high $450 (Citigroup). Notably, that average sits below the ~$367 price even after a June wave of upgrades — Cantor and Raymond James to $425, Oppenheimer to $400, UBS to $375 — so the most bullish desks still see room while the average reads the stock as already past fair value. MainRatios' own conservative models land far lower, around $86–$218, because they discount Lam's historical growth rather than the AI-cycle premium.
