Lam Research Earnings Preview: Can HBM and NAND Expansion Keep Driving Equipment Orders?

The core question for Lam Research earnings is whether HBM and NAND expansion can continue pushing AI memory demand into equipment orders. HBM drives DRAM wafers, advanced packaging, and more complex processes, while NAND benefits from AI data center eSSD demand, higher-layer 3D NAND, and high-aspect-ratio etch requirements. The market will not only watch whether Lam delivers strong revenue, but also systems revenue, customer support revenue, gross margin, regional demand, and next-quarter guidance to judge whether this memory WFE upcycle has moved from price recovery into real expansion.

Key Takeaways

• Lam Research will hold its June quarter earnings call at 2 p.m. PDT on July 29, 2026.
• March quarter revenue was $5.841 billion, and June quarter guidance is $6.6 billion plus or minus $400 million.
• HBM expansion can drive demand for DRAM, advanced packaging, TSV, etch, deposition, and cleaning.
• NAND upside comes from higher 3D NAND layer counts, eSSD demand, and high-aspect-ratio etch.
• The market will focus on systems revenue, customer support revenue, gross margin, and next-quarter guidance.
• If orders are strong but margins or regional demand come under pressure, LRCX can still be volatile after earnings.

Why Are Lam Research Earnings an Important Signal for HBM and NAND Expansion?

Lam Research is an important window into HBM and NAND expansion because it does not directly sell memory chips, but it supplies key equipment for memory manufacturing and advanced packaging. HBM requires more DRAM wafers, advanced packaging, and complex interconnects. NAND needs to move toward higher-layer 3D structures. These changes raise demand for etch, deposition, cleaning, metallization, and customer support. If memory makers truly restart expansion, Lam's systems revenue and service revenue often provide early signals.

The company has announced that it will hold its June quarter earnings call at 2 p.m. PDT on July 29, 2026. Since today is July 28, 2026, the results have not yet been released. The market is currently trading around the prior quarter's strong results, June quarter guidance, AI memory demand, and expectations for higher memory WFE.

Lam's industry position is clear. In its discussion of etch and deposition trends in the AI era, the company noted that NAND, logic, DRAM, and packaging are all moving toward 3D, and the 3D era requires deeper etch and more precise deposition. That directly explains why HBM and NAND expansion are not only memory-maker revenue stories; they can also pass through into semiconductor equipment orders.

The value of this earnings report is that it can help separate memory price increases from real equipment-order expansion. If HBM and NAND are only recovering in price, equipment orders may not rise dramatically. If customers are increasing wafer starts, moving to new nodes, expanding advanced packaging, and upgrading 3D NAND layers, Lam is more likely to see sustained upside in systems revenue, orders, and customer support.

Summary: Lam Research is an equipment-side observation point for HBM and NAND expansion. The more HBM and NAND demand moves into DRAM wafers, 3D NAND, advanced packaging, etch, and deposition steps, the more Lam's systems and customer support revenue can benefit.

How Should Investors Read June Quarter Guidance: Can $6.6 Billion Revenue Be Raised Again?

Lam's June quarter guidance already reflects meaningful upside. Its March 2026 quarter results showed revenue of $5.841 billion, GAAP gross margin of 49.8%, non-GAAP gross margin of 49.9%, and non-GAAP EPS of $1.47. Management guided June quarter revenue to $6.6 billion plus or minus $400 million, gross margin to 50.5% plus or minus 1 percentage point, and EPS to $1.65 plus or minus $0.15.

This guidance means the market already expects Lam to continue growing strongly in the June quarter. If revenue approaches the $7.0 billion guidance high end, it would suggest AI memory, advanced logic, and customer investment timing may be stronger than management originally assumed. If revenue lands only near the midpoint, it is still growth, but may not be enough for a stock carrying high expectations. The common post-earnings debate for semiconductor equipment stocks is the gap between "good numbers" and "good enough."

Systems revenue and customer support revenue should be read separately. Systems revenue is closer to new equipment demand, and if memory customers increase HBM, DRAM, or NAND CapEx, it is usually more sensitive. Customer support revenue includes service, spares, upgrades, and non-leading-edge equipment, showing installed-base resilience. If both rise together, Lam is not only benefiting from new equipment orders, but also from stable service revenue tied to a larger installed base.

Regional mix should not be ignored. In the March quarter, China, Korea, and Taiwan represented large shares of Lam revenue. That shows Asian memory and advanced manufacturing customers remain central, but it also means export restrictions, customer concentration, regional CapEx timing, and currency changes can affect guidance quality. On the earnings call, management commentary on Korea, China, Taiwan, memory, and foundry/logic will carry more information than a single EPS number.

Summary: The key June quarter hurdle for Lam is whether revenue can approach the $6.6 billion guidance high end, margins can hold near 50%, and systems revenue and customer support revenue can both strengthen. Next-quarter guidance and management's tone on memory WFE may matter more than a single-quarter beat.

How Do HBM and Advanced Packaging Push Lam Equipment Orders Higher?

HBM expansion can push Lam equipment orders higher because it passes upstream into DRAM wafer manufacturing and downstream into advanced packaging and interconnect structures. HBM is not simply stacking DRAM dies. It involves higher yield requirements, more complex TSV, wafer thinning, bonding, RDL, interposers, and package validation. The faster AI GPU and AI ASIC platforms iterate, the more memory makers need capacity expansion and process upgrades, and the more equipment demand can continue.

TrendForce's HBM pricing and capacity analysis noted that HBM wafer input as a share of total DRAM wafer input among the top three DRAM suppliers is expected to rise from about 18% at the end of 2025 to about 22% by the end of 2026, then to about 30% by the end of 2027. This shows HBM is taking a growing share of advanced DRAM capacity, which means memory makers need clearer capital spending to avoid HBM and conventional DRAM crowding each other out.

HBM equipment elasticity also comes from generational upgrades. HBM3E, HBM4, and higher stack counts increase bandwidth, capacity, and power-management requirements. To meet AI accelerator customer roadmaps, memory makers need not only more capacity, but also more stable process windows and higher yields. If Lam can improve process control and throughput in DRAM and advanced packaging steps, it can translate the HBM cycle into stronger equipment orders.

Advanced packaging strengthens the same logic. In May 2026, Lam announced a Panel-Level Packaging Center of Excellence in Salzburg, Austria, intended to expand panel-level processing R&D and help customers evaluate, optimize, and scale packaging solutions for the AI era. Panel-level packaging matters because it could support advanced packaging expansion with larger area, higher throughput, and lower unit cost. If HBM expansion and panel-level packaging move forward together, Lam's order logic becomes more balanced than a single DRAM expansion story.

Investors should avoid one misconception: strong HBM demand does not guarantee Lam orders rise linearly. If memory makers mainly improve profitability through price increases, existing-line optimization, or long-term customer contracts, equipment-order elasticity may lag HBM revenue growth. Lam's order elasticity becomes more visible only when HBM demand forces customers to add wafer capacity, upgrade processes, expand advanced packaging, and improve yields.

Summary: HBM and advanced packaging matter to Lam because they can simultaneously drive DRAM wafers, TSV, panel-level packaging, deposition, etch, and customer support demand. If management clearly says HBM, DRAM, and advanced packaging customer investment remains strong, the LRCX order thesis becomes more solid.

Can NAND Expansion Become a Second Growth Line: 3D NAND Layers and AI Storage Demand

NAND is Lam's second important growth line because AI data centers need not only HBM, but also eSSD, high-capacity storage, and 3D NAND with lower cost per bit. If NAND moves from price recovery into capacity expansion and technology upgrades, Lam's opportunity in high-aspect-ratio etch, deposition, fill, cleaning, and installed-base upgrades becomes more visible. If NAND customers only restore profitability while still controlling CapEx, equipment-order elasticity will be weaker.

Lam's cryogenic etching solution directly explains the 3D NAND technology path: AI applications are driving memory technology forward, and chipmakers need to scale beyond 200-layer 3D NAND. Lam Cryo 3.0 is aimed at future 400-layer and higher 3D NAND devices for device-critical channel hole etch. For equipment orders, the higher the layer count, the deeper and narrower the structure, and the more complex stress and yield challenges become, the greater the need for etch and deposition intensity.

AI storage demand is a new variable in NAND recovery. Training and inference require not only GPUs and HBM, but also larger data sets, vector databases, caching, logs, model checkpoints, enterprise data lakes, and high-performance SSDs. In its Q1 2026 results, SK hynix listed eSSD alongside HBM and high-capacity server DRAM as a high-value product demand source, showing that NAND-related demand is no longer only a consumer electronics cycle.

The real question is whether NAND customers move from price recovery into expansion. If NAND price increases mostly come from supply cuts, equipment orders may not rise immediately. If customers believe AI eSSD, enterprise storage, and higher-layer 3D NAND demand can last, they will be more willing to invest in new equipment and technology upgrades. Lam's earnings commentary on memory customer spending, 3D NAND, and installed-base upgrades will directly affect market judgment.

Summary: NAND can become Lam's second growth line, but only if customers do more than enjoy price increases. They need to restart 3D NAND layer upgrades, eSSD expansion, and high-aspect-ratio etch investment. Lam's cryogenic etching, deposition, and customer support capabilities are central to judging NAND equipment-order elasticity.

Valuation Pressure: Why Strong Orders May Still Not Be Enough

Strong orders may not be enough to support LRCX after earnings because the market has already priced in HBM, NAND, advanced packaging, and memory WFE recovery. Lam's fundamentals may be strong, but if the June quarter only lands in the mid-to-high guidance range, next-quarter guidance is conservative, margins miss expectations, or regional demand diverges, the stock can still move sharply. In a high-expectation phase for semiconductor equipment stocks, the risk is being strong, but not stronger.

Lam's valuation pressure comes from three layers. First, AI storage demand has already been repeatedly priced by the market, especially after HBM and NAND price increases. Second, equipment orders are cyclical, and customers may place concentrated orders across a few quarters before entering digestion. Third, Asian customers represent a large share of Lam revenue, and export restrictions, regional capital spending, and customer concentration can all affect how investors judge order quality.

A more practical way to read the earnings report is to divide signals into three layers. The first layer is whether revenue, EPS, and gross margin exceed guidance. The second is whether systems revenue, customer support, regional mix, and cash flow are all healthy. The third is whether management remains optimistic on HBM, DRAM, NAND, advanced packaging, and FY2027 capital spending. Only if all three layers are positive can valuation pressure be easier to absorb.

If the opposite combination appears, such as good revenue but weak margins, strong HBM but cautious NAND, or strong systems revenue without a stronger next-quarter guide, the market may treat LRCX as a stock with expectations already full. For ordinary investors, earnings should not be judged only by one sentence about strong AI demand. The questions are whether orders are sustainable, margins can hold, and customer investment is broad-based.

Summary: Lam's post-earnings stock reaction depends not only on whether equipment orders are strong, but whether orders, margins, systems revenue, customer support, regional demand, and next-quarter guidance are all strong together. The more HBM and NAND demand has already been priced in, the higher the earnings bar becomes.

How to Track LRCX After Earnings: From Equipment Orders to Trading Costs

After earnings, LRCX is best tracked within the semiconductor equipment and AI memory chain, not as a standalone EPS story. Lam, AMAT, KLAC, ASML, TER, MU, SK hynix, Samsung, and TSMC all cross-check each other. Memory maker CapEx determines equipment orders, while equipment company orders validate whether AI memory expansion is real. If HBM, NAND, advanced packaging, and WFE all strengthen together, Lam's order logic becomes more complete.

For earnings trades, LRCX risk lies in volatility and expectation gaps. The company will hold its call after the market closes, and the market will quickly process revenue, EPS, margins, guidance, memory demand, and regional mix. After-hours liquidity, bid-ask spreads, order types, and market depth may differ from regular hours. Looking only at headline beats can miss execution slippage and second-day moves driven by analyst interpretation.

If you need to track LRCX, AMAT, KLAC, TER, MU, or other AI memory-chain names, Biya U.S. stock quotes can help you build a watchlist that compares semiconductor equipment, memory, advanced packaging, and AI chip companies. During earnings season, the point is not only price movement, but also volume, bid-ask spreads, order types, and premarket or after-hours liquidity.

Trading costs also need to be checked in advance. Biya is a global multi-asset trading wallet that supports U.S. stocks, Hong Kong stocks, cryptocurrencies, and other assets. In U.S. stock trading scenarios, Biya charges $0 commission for U.S. stock trades, while platform fees, external institutional fees, and other costs are subject to Biya U.S. stock trading fees and order display. If you later need to manage watched assets, complete account information, or prepare for trading, you can enter the personal account system through Biya registration, and you can also use the Biya App to track post-earnings market moves. Availability of related services depends on the user's location, identity verification results, platform rules, and applicable laws and regulations.

Summary: Tracking Lam Research after earnings means watching equipment orders, memory WFE, HBM, NAND, advanced packaging, margins, and trading costs together. LRCX is a high-volatility semiconductor equipment stock, so earnings trades should not be judged only by direction; liquidity, spreads, and personal risk tolerance matter too.
