Lam Research (LRCX) Earnings Date & Reports

Key Takeaways

• Lam Research posted record revenue of $6.72 billion in its fourth quarter of fiscal 2026, up 30% year over year and above the roughly $6.67 billion consensus estimate.
• Non-GAAP diluted earnings per share (EPS) came in at $1.82, beating the consensus estimate of about $1.69 and climbing nearly 37% from the prior-year quarter.
• Non-GAAP gross margin reached 52.0% and non-GAAP operating margin hit a record 38.4%, driven by pricing, scale efficiencies, and favorable product mix.
• NAND (a type of flash memory) revenue more than doubled sequentially, lifting memory to 46% of systems revenue amid strong artificial intelligence (AI)-driven storage demand.
• Management raised its calendar 2026 wafer fabrication equipment (WFE) spending outlook to the low-$150 billion range and guided to strong fiscal 2027 first-quarter growth.

Earnings Context and Why It Matters

Lam Research, a leading supplier of semiconductor wafer fabrication equipment, sits at the center of the AI buildout reshaping the chip industry. Its tools for deposition and etch are critical to producing the advanced memory and logic chips that power AI data centers. This fourth-quarter report therefore carried outsized weight: investors were watching whether AI-driven demand for memory and leading-edge foundry capacity could sustain the company's momentum. After three consecutive record quarters, the key questions were whether pricing power and mix could keep expanding margins, and whether forward guidance would confirm that the upcycle still has room to run into fiscal 2027.

Reported Results

For the fourth quarter of fiscal 2026, ended June 28, 2026, Lam Research reported revenue of $6.72 billion, a 30% increase year over year and roughly 15% higher sequentially. Non-GAAP diluted EPS of $1.82 topped the consensus estimate of about $1.69, while GAAP (Generally Accepted Accounting Principles) diluted EPS was $1.81. Net income on a GAAP basis was $2.28 billion.

Profitability set new records. Non-GAAP gross margin rose 210 basis points sequentially to 52.0%, which management called the highest quarterly level in two decades, and non-GAAP operating margin expanded 340 basis points to 38.4%. Systems revenue grew 23.6% year over year to $4.25 billion, while customer support-related revenue jumped 42.6% to $2.47 billion — a third consecutive record for the segment.

For the full fiscal year 2026, revenue increased 26% to $23.23 billion, with GAAP diluted EPS of $5.76 and non-GAAP diluted EPS of $5.82. Looking ahead, the company guided first-quarter fiscal 2027 revenue to $8.10 billion plus or minus $400 million, with non-GAAP EPS of $2.15 plus or minus $0.15 — both well above consensus expectations at the time.

Market Reaction and Investor Sentiment

The initial market response was mixed. Shares fell about 6.4% during the regular session on July 29, 2026, to close near $252, a move analysts attributed largely to broader semiconductor-sector volatility rather than the results themselves. The stock then rebounded in after-hours and pre-market trading as investors digested guidance that came in well above expectations, rising roughly 5% to 8%.

Over the following month, Lam Research shares added about 7%, outperforming the broader market, as analysts raised estimates in response to the strong outlook. Analysts at firms including Citi and Evercore ISI described both the results and guidance favorably. The general sentiment is constructive, though concerns about valuation, China-related export restrictions, and the cyclical nature of WFE spending remain key risk factors in the debate.

Forward Outlook and Key Factors to Monitor

The most consequential signal from this report was management's raised view on industry spending. Lam now expects calendar 2026 WFE spending in the low-$150 billion range, up from a prior $140 billion outlook with upside bias, and it sees an "extraordinary setup" for WFE growth in 2027. Management ranked next year's growth drivers as DRAM first, foundry logic second, and NAND third.

Investors should watch several factors in the coming quarters. First is whether the September-quarter guidance of $8.10 billion in revenue, implying more than 20% sequential growth, is delivered or exceeded. Second is margin sustainability: management signaled targets of mid-50% gross margin and mid-40% operating margin over several years, and execution against those goals will be closely tracked.

Third, the geographic mix is shifting. China's share of revenue fell to 26% from 34% sequentially, while Taiwan reached a record 27%. Export-control developments and any new trade restrictions remain a live risk. Finally, advanced packaging — tracking to more than 70% year-over-year growth — and the expansion of the customer support business both represent potential sources of more durable, higher-margin revenue that could smooth out equipment cyclicality.
