Hey there, bargain hunter.
Somewhere between the chip sector’s ongoing bear market drama and the semiconductor selloff bleeding out of Seoul this week, one name has quietly done something the rest of the sector has not: it just kept going up.
Lam Research (NASDAQ: LRCX) is up sharply in 2026. The stock now sits near $284. And tomorrow night — July 29 — it reports fiscal Q4 2026 earnings after the close. The options market is watching. Morgan Stanley is watching. And if you have any interest in the AI infrastructure trade at the equipment layer, you should be watching too.
What the numbers look like going in
Analysts expect Lam to post Q4 revenue of roughly $6.65 billion and earnings of about $1.69 per share. That would be a significant step-up from last quarter. Last quarter, the company reported non-GAAP EPS of $1.47, beating the $1.36 consensus by $0.11, on revenue of $5.84 billion against expectations of $5.70 billion.
Morgan Stanley analyst Shane Brett is projecting Q4 revenue of $7.4 billion, above the $7 billion consensus, noting that Lam has topped Wall Street estimates by an average of 9% over the last five quarters.
That is not a company missing numbers. That is a company systematically beating them while analysts scramble to keep up.
The market it sells into is expanding fast
Here is the real story. Lam does not make chips. It makes the machines that etch and deposit the microscopic layers that turn a blank silicon wafer into a working chip. For years, that business grew slowly and steadily, until the AI megatrend accelerated top-line growth.
The wafer fab equipment market is projected by Lam’s CEO to reach about $140 billion in calendar 2026, with management describing a “bias to the upside.” As you may recall, Lam has also discussed a roughly $40 billion NAND conversion spending opportunity, with the majority now expected to occur before the end of calendar year 2027.
Morgan Stanley also expects Lam to raise its full-year WFE market forecast, from $140 billion to $145 billion, an increase of 32% year over year. If that happens tomorrow, every chip equipment name moves.
Why HBM is the hidden driver
Lam’s etch and chemical vapor deposition tools are the gating technology for HBM — high bandwidth memory — the memory type that every major AI accelerator depends on for bandwidth. As AI model complexity and training compute scales, demand for HBM grows super-linearly. Every $1 billion in HBM capacity expansion drives significant Lam equipment spend.
Advanced packaging and AI-driven demand are accelerating growth.
Slight tangent, but it matters: this is exactly why the Kimi K3 China AI model announcement last week hit chip stocks so hard. The fear was that a more efficient model means less compute demand, which means less HBM, which means less Lam equipment spend. The bull case says efficiency gains eventually lead to more deployments, not fewer. Tomorrow’s guidance will tell you which side has the better argument.
The valuation debate
At 38x forward P/E, Lam delivers 40.8% earnings growth and returned $1.16 billion in buybacks in a single quarter. Compare that to KLA, which trades at 41x forward P/E on just 12% earnings growth — Lam’s 38x with triple the growth looks like the stronger value.
Analysts tracking LRCX forecast revenue to increase from $23.3 billion in fiscal 2026 to $44.37 billion in fiscal 2030, with adjusted EPS projected to expand from $5.68 to $12.63 over the same period.
That is not a valuation you pay for a mature industrial. That is a valuation you pay for a compounding infrastructure monopoly with secular AI demand underneath it.
What could go wrong
Short-term volatility is expected from trade restrictions and global economic uncertainty. China export controls remain the biggest structural risk — Lam has significant China revenue exposure, and any escalation directly compresses revenue visibility. The stock is also up sharply in a year, which means the bar tomorrow is genuinely high. A beat without a WFE guidance raise probably doesn’t move it much.
Consensus Q4 revenue sits around $6.65 billion (with some estimates clustering closer to $6.7 billion), with Morgan Stanley at $7.4 billion. Fiscal 2027 guidance will set the tone for the next two quarters.
What to watch tomorrow
- Revenue vs. ~$6.65 billion consensus (Morgan Stanley’s bar is $7.4 billion)
- WFE market guidance — does it move from ~$140 billion toward ~$145 billion?
- Advanced packaging revenue growth rate
- NAND conversion spending timeline update
- FY2027 revenue outlook — this is the number that moves the stock
- China exposure commentary — any escalation language changes the calculus
With a strong “Strong Buy” tilt in the analyst community and an average target in the mid-$300s to around $400 depending on the source, the stock looks attractive at its current price near $284.
Whether that gap closes tomorrow depends entirely on whether Archer shows up with a bigger number on the WFE market and a FY2027 guide that justifies the run. The setup is there. The bar is also high. That is usually how the interesting trades work.
