Lam Research (LRCX) Posts Record Revenue and Earnings in Fiscal Q4 Amid AI-Driven Demand
Key Takeaways
- Record revenue: Lam Research reported $6.72 billion in revenue for the fiscal fourth quarter ended June 2026, up 30% year-over-year and surpassing the consensus estimate of approximately $6.66 billion.
- Earnings beat: Non-GAAP (adjusted) diluted earnings per share reached a record $1.82, exceeding the Zacks Consensus Estimate of $1.69 by roughly 8%.
- Margin expansion: Non-GAAP gross margin climbed to 52.0%, a 20-year high, while non-GAAP operating margin expanded to 38.4%, both exceeding company guidance.
- NAND resurgence: Revenue from NAND (non-volatile memory) more than doubled sequentially, reflecting robust demand for storage in AI systems.
- Bullish guidance: The company guided for fiscal Q1 2027 revenue of $8.1 billion and non-GAAP EPS of $2.15, both well above analyst expectations.
- Full-year records: Fiscal 2026 revenue totaled $23.23 billion (up 26% YoY) and diluted EPS reached $5.82 (up 41%), ahead of profitability goals set at the company's 2025 investor day.
Earnings Context and Why It Matters
Lam Research's fiscal fourth-quarter results carry outsized importance as a bellwether for the broader semiconductor equipment industry. As a leading supplier of wafer fabrication equipment — particularly in etch and deposition — LRCX's performance reflects the health of global chip manufacturing investment. The June quarter report arrived at a moment when AI-driven infrastructure spending is reshaping the semiconductor landscape, with major chipmakers committing to multi-year fab construction plans. Following four consecutive quarters of record revenue and a 165% stock surge over the prior 52 weeks, expectations were elevated. This earnings release served as a critical checkpoint on whether AI-related demand can sustain the company's extraordinary growth trajectory and whether elevated valuation multiples remain justified.
Reported Results
LRCX posted June quarter revenue of $6.72 billion, a 15% sequential increase and 30% year-over-year growth, exceeding both the midpoint of management's guidance range and the Wall Street consensus. Non-GAAP diluted earnings per share came in at $1.82, beating analyst estimates by $0.13 to $0.14 per share. GAAP net income rose to $2.28 billion, or $1.81 per share, compared with $1.72 billion, or $1.35 per share, in the same quarter a year ago.
The standout metric was profitability. Non-GAAP gross margin reached 52.0%, a level the company has not achieved in two decades, driven by pricing actions, operational efficiencies, favorable product mix, and scale benefits. Non-GAAP operating margin expanded to 38.4%, a record. The Customer Support Business Group (CSBG) delivered its third consecutive record quarter at nearly $2.5 billion, up 17% sequentially and 43% year-over-year, fueled by record upgrade revenue and growing adoption of Equipment Intelligence-enabled services.
Memory accounted for 46% of systems revenue, up from 39% in the prior quarter, led by a doubling of NAND revenue as customers accelerated conversions to 256-layer and higher devices for enterprise solid-state drives. DRAM (dynamic random-access memory) revenue held roughly flat at record levels. Foundry represented 44% of systems revenue, with investment in 2-nanometer and 3-nanometer nodes and advanced packaging largely offsetting lower mature-node spending from Chinese customers.
For the full fiscal year 2026, Lam Research reported record revenue of $23.23 billion and diluted EPS of $5.82, rising 26% and 41%, respectively, from fiscal 2025. I also checked comparable names in the sector using Tickeron’s AI Screener to see how LRCX stacks up on key metrics.
Market Reaction and Investor Sentiment
Market reaction to Lam Research's results was notably bifurcated. Shares fell 7.04% during regular trading on July 29, closing at $250.63, as broader market jitters and potentially some profit-taking weighed on the stock ahead of the print. However, the after-market response told a different story: the stock rebounded 5.31% to approximately $265.75 as investors absorbed the magnitude of the earnings beat and, more importantly, the September quarter guidance that handily exceeded consensus. The after-hours recovery suggests that while some caution had been priced in — perhaps around China exposure or sustainability of NAND demand — the forward outlook was sufficiently compelling to restore bullish sentiment. With the company having now beaten EPS estimates in every quarter for at least the past year, investor confidence in management's execution and the durability of AI-driven equipment demand remains a central theme.
Forward Outlook and Key Factors to Monitor
Lam Research raised its calendar 2026 wafer fabrication equipment (WFE) spending forecast to the low-$150 billion range, up from a prior estimate of approximately $140 billion. This upward revision, paired with September quarter guidance calling for $8.1 billion in revenue and non-GAAP EPS of $2.15, signals management's conviction that the current upcycle has substantial runway ahead.
Several factors will shape the quarters ahead. First, the sustainability of NAND-related spending will be a focal point. Management indicated that roughly $40 billion in NAND conversion investments is being pulled forward, with the majority expected before the end of calendar 2027. Investors will monitor whether this pull-forward represents durable demand or borrows from future periods.
Second, China exposure remains a variable. Mature-node spending from Chinese customers declined during the quarter, offset by advanced-node investments elsewhere. Any further regulatory tightening on semiconductor equipment exports could introduce headwinds.
Third, Lam's expanding served available market (SAM) — which management expects to reach slightly above the mid-30s percentage of total WFE — and growing advanced packaging revenue (projected to rise more than 50% in calendar 2026) represent structural growth drivers that could outlast cyclical fluctuations. The company's investment in robotics, collaborative maintenance tools, and Equipment Intelligence services also positions CSBG as a recurring revenue engine that may help smooth equipment-cycle volatility over time.
Finally, with the stock trading at a forward price-to-earnings ratio well above the semiconductor industry average, the burden remains on Lam Research to continue delivering outsized growth to support its premium valuation. The September quarter will provide the next major checkpoint. From what I see, these trends warrant close attention in the coming months.
