Record $5.84B Revenue + First $2B+ CSBG Quarter; CY26 WFE Raised to $140B "Bias Up" and NAND $40B Pulled Forward — Maintaining Outperform on Multi-Year Compounding Setup

Results vs. Consensus

Quarter-over-Quarter Comparison

Year-over-Year Comparison

Revenue Assessment

Q3 revenue of $5.84B is the third consecutive record (Sep $5.32B → Dec $5.34B → Mar $5.84B), with the 9% sequential and 24% year-over-year growth rates demonstrating that the structural setup of the prior two quarters has now broken into a clear acceleration phase. The +24% YoY growth materially outperforms the CY26 WFE growth rate of +27% (from $110B CY25 to $140B+ CY26) — the 2.5-3x SAM-vs-WFE outperformance has now closed somewhat as Lam's growth converges with the industry growth (a structural feature of being now at "slightly more than mid-30%s" SAM share), but the absolute dollar contribution is materially larger. The sequential acceleration into the June guide of $6.6B (+13% sequential) implies June quarter +30%+ YoY — extending the acceleration phase rather than flattening it. The Lam-specific drivers compound: foundry leading-edge, DRAM HBM + 1c node, NAND conversion pull-forward, advanced packaging +50% CY26 growth, CSBG installed-base monetization, and Equipment Intelligence + Dextro cobot commercial traction.

Critically, the foundry-DRAM-NAND mix shift this quarter reflects healthy diversification rather than concentration risk. Foundry moved from 59% to 54% of systems on essentially flat dollar revenue (~+35% YoY); DRAM increased to a record 27% on the HBM continuation plus the 1c node ramp (DDR5/LPDDR5); NAND ticked up to 12% with explicit guidance that growth continues through the remainder of the year. Korea and Taiwan each hit record dollar levels at 23% of revenue — a meaningful broadening from the historical regional concentration. The 11-consecutive-quarter growth streak is a structural execution proof point that the market typically does not give credit for in advance.

Margin Assessment

Q3 gross margin of 49.9% landed at the high end of the 49% ± 1pp guide and was up 20bps sequentially despite acknowledged customer mix dynamics. The drivers are now well-disclosed: (a) global manufacturing footprint efficiency — particularly Malaysia and the proximity-to-customer playbook the CFO laid out 4-5 years ago is delivering shorter logistics, lower labor, and better supply chain economics; (b) tool maturity reducing installation + warranty cost on new product introductions; (c) Lam being "paid for the value we're delivering to customers" via pricing discipline on next-generation tool sets. The June guide of 50.5% (+60bps from Mar 49.9%) is the most material disclosure — Lam is now hitting the long-stated target model of "above 50% gross margin" four years ahead of plan. The CFO's explicit instruction to "model gross margin for the rest of the year roughly at the levels we just guided you to in June" caps near-term enthusiasm but confirms 50%+ as the new operating regime.

Operating margin at 35% (high end of guide) demonstrates the embedded leverage on the revenue ramp. OpEx of $866M (+5% sequential) reflects seasonal employee-related costs + headcount additions (+900 QoQ to 20,600). R&D at 68% of OpEx is being deliberately scaled — the CFO was explicit that "we're going to grow spending this year because, frankly, we can afford to do so." The June guide of 36.5% operating margin materially exceeds the prior "greater than 35%" long-term model. Both Tim and Doug acknowledged the need to update the long-term framework "later in the year," which sets up either an Investor Day or a quarterly call disclosure event as a re-rating catalyst.

EPS & Cash Flow Assessment

Q3 EPS of $1.47 exceeded the $1.35 ± $0.10 guide high end by $0.02 and beat the Street $1.38 by $0.09. The June guide of $1.65 ± $0.15 implies another sequential record (+12% sequential). The compounding lever continues to operate: (a) revenue +9% QoQ, +24% YoY; (b) gross margin +20bps QoQ, +140bps YoY; (c) operating margin +70bps QoQ, +300bps YoY; (d) share count flat to slightly declining via the ASR + open-market buybacks ($800M at avg $211/share). The tax rate of 9.2% was a one-time benefit on equity-comp vesting that won't recur quarterly, but the CFO guided full-year CY26 below the mid-teens — well below the historical mid-teens rate.

Capital return was structurally aggressive — $800M buyback (including $200M ASR) + $326M dividends + $750M unsecured notes paydown = 139% of free cash flow returned. Cash declined to $4.8B from $6.2B, a $1.4B sequential decrease driven by the combined capital return + debt retirement + $332M capex. The CFO was explicit that "we don't need down payments" — customer down payments declined ~$300M sequentially to the lowest level in 4 years, reflecting that growth is coming from large-multinational customers who don't put down payments, rather than the smaller (often China) customers who do. This is a high-quality cash flow signal: the demand is from credit-worthy customers, not from customers needing to lock up Lam's capacity through prepayments. $4.3B remains on the board buyback authorization, providing multi-quarter optionality.

Segment Performance

DRAM — Record 27% of Systems on 1c Node Transition + HBM Continuation

DRAM hit a record 27% of systems revenue (vs 23% in Q2, 16% in Q1 FY26), driven by the industry transition to 1c-generation devices for HBM3E/4 and DDR5/LPDDR5. The structural disclosure was the explicit framing of Lam's silicon-carbide ALD (Stryker) as the tool of record at all leading memory makers for bitline spacer applications. As feature dimensions shrink at the 1c node, the industry is moving from traditional silicon nitride furnace-deposited dielectrics to ALD-deposited low-k SiOC. Studies cited by the CEO show the re-architected device structures combined with low-k bitline spacers can reduce capacitance by >60%. Lam's total dielectric deposition SAM in DRAM grows >20% with the 1c transition.

Beyond the dielectric deposition franchise, Lam's HBM 3E/4 conductor etch and EUV-related applications continue to ramp. The Stryker plasma source is structurally differentiated — high productivity, conformal, tunable low-k films. With Q3 representing the third consecutive DRAM record (16% → 23% → 27% of systems mix), the franchise has structurally re-rated as the AI-memory bull case has compounded. Korea hitting a record dollar level at 23% of total revenue corroborates the DRAM-driven mix shift, since the bulk of Korea revenue is Samsung + Hynix DRAM (plus some NAND).

Assessment: DRAM is now the most-improved segment in the post-Investor-Day arc. The Q3 record at 27% mix combined with the >20% dielectric deposition SAM expansion at the 1c node implies DRAM holding 25-30% of systems mix is structurally durable. We model DRAM at ~$5-6B FY27 (vs ~$3.5B FY25), with the upside scenario tied to HBM4E/HBM5 timing through CY27-28.

Foundry — 54% of Systems; First Dielectric Etch Wins at Key Customer

Foundry at 54% of systems is down from Q2's 59% on mix shift (DRAM ramped), but foundry dollar revenue was approximately flat sequentially and +35% year-over-year. The drivers remain the multi-customer leading-edge cycle (TSMC N2/A16, Samsung 2nm, Intel 18A) plus ongoing mature node investment plus advanced packaging strength. The structurally important new disclosure was the first dielectric etch wins at a key foundry/logic manufacturer — these were not previously Lam wins, indicating share-of-wallet expansion at a specific customer where Lam had been blocked. This is a meaningful structural win in a competitively contested category.

Advanced packaging within foundry is growing materially. The CY26 advanced packaging growth outlook was raised to ">50%" from the prior ">40%" at the Q2 call. The drivers: copper plating + TSV etch leadership in HBM, increasing complexity at chiplet-style integration, and the use of PECVD in underfill applications. The CFO specifically called out PECVD in advanced packaging underfill as a major contributor to last year's PECVD share gain.

Assessment: Foundry remains the structural backbone of the franchise — 50-60% of systems mix is the operating range. The dielectric etch win at the new customer plus advanced packaging +50% CY26 growth combine to add multi-hundred-million-dollar revenue contributions. We model foundry contributing $13-15B of FY27 revenue.

NAND — 12% on Pull-Forward of $40B Conversion Cycle

NAND mix at 12% (vs 11% in Q2) is the smallest in dollar terms of the three device segments but is now the most structurally re-rated. The CEO disclosed the structural pull-forward of the $40B NAND conversion spending program — previously framed in early 2025 as occurring "over several years," now expected to have "the majority of spending occurring before the end of calendar year 2027." The drivers are explicit: data-center NAND bits are expected to exceed PC + mobile combined this year; AI data-center economics require QLC + >200-layer devices for SSD performance; the installed-base wafer capacity has declined >20% from prior highs as customers convert to higher-layer-count tools; the conversion is being supplemented by greenfield capacity additions to meet bit demand growth.

Lam has the largest installed base of 3D NAND tools in the industry. The conversion-plus-greenfield combination is asymmetric in the company's favor because: (a) conversions use Lam's high aspect ratio cryo etch + dielectric stack deposition + worldline metallization + backside stress management + gap fill technologies; (b) greenfield drives full-tool-set sales of the same product portfolio plus additional tool count as layer counts increase. The Vantex and Flex dielectric etch toolsets are described as having the industry's highest power density and productivity for dielectric channel hole edge applications, where Lam holds market-leading share. The Kioxia-style customer switch to Kio (Lam's conductor etch) in the middle of a production ramp due to superior defect performance is the kind of structural win that compounds over the conversion cycle.

Assessment: NAND is the highest-conviction CY26-27 upside vector. With AI memory-hierarchy adoption accelerating + the $40B conversion now front-loaded + greenfield needed on top, we model NAND at ~$4.5-5.5B FY27 (vs ~$2.2B FY25). The CY27 NAND revenue contribution could approach 18-22% of systems mix — a material re-acceleration from the current 12%.

China — 34% with Expected Further Decline

China region was 34% (vs 35% in Q2). The CFO explicitly guided that China revenue in the June quarter will decline from current levels. The CY26 China narrative is being absorbed cleanly: WFE in China is "flattish year-over-year from 2025 to 2026, maybe up a little bit" while global multinational customer growth materially exceeds China growth, causing China-as-percent-of-total to decline naturally. A secondary dynamic is that global multinationals operating fabs in China are spending more, broadening the geographic exposure within the China total.

The customer-down-payment decline of ~$300M sequentially (to the lowest level in 4 years) is correlated with the China dynamic — smaller customers (often China-domiciled) provide down payments, while the larger multinationals now driving growth do not. This is a quality-of-revenue improvement: cash flow is increasingly coming from credit-worthy multinational customers rather than smaller customers needing capacity commitments.

Assessment: China normalization on track. The decline to ~30% of revenue by year-end is structurally appropriate and removes a key bear-case concentration argument. We assume China remains a 25-30% revenue contributor through CY27.

CSBG — First $2B+ Quarter at $2.1B

CSBG hit a structural milestone with the first $2B+ quarterly revenue at $2.1B (+6% sequential; +25% year-over-year). Growth was broad-based across spares, upgrades, and services. Service revenue grew mid-teens sequentially, reflecting high industry utilization (which both Tim and Doug repeatedly emphasized as "very, very high" or "full out"). The new disclosure was a foundry/logic Equipment Intelligence services agreement for critical deposition applications — extending Lam's Equipment Intelligence offering from the original memory customer base into foundry, where the addressable opportunity is materially larger.

The Dextro cobot deployment expanded to 8 Lam tool types (up from 6 in Q2), with the introduction of next-generation Dextro packing 10x more compute power than the first generation in a smaller footprint. The first deposition Dextro cobot ships in Q4. Customers using Dextro are reporting both improved output (faster tool return-to-production after maintenance) and improved yield (better-placed parts inside chambers reducing defectivity). The installed-base monetization story is structurally compounding — at 100,000+ chambers and growing, the recurring revenue floor is high and growing.

The CFO indicated CSBG should sustain "roughly at these levels as we go through the remaining quarters in the calendar year, maybe up a little bit." Given the Q3 record + the foundry Equipment Intelligence + cobot expansion + continued utilization tailwind, we view this as conservatively framed.

Assessment: CSBG is now an $8B+ annualized run-rate business (vs $7.2B CY25) with structural upside from the Equipment Intelligence/cobot/services innovations layering on top. We model CSBG at $8.5-9.0B FY27.

Key Topics & Management Commentary

Overall Management Tone: Confident and execution-focused with multiple structural-disclosure events. The CEO opened with the framing that "Lam is off to a solid start in calendar year 2026" and tied the print directly to the multi-year compounding thesis. The CFO's commitment to update the long-term operating margin model "later in the year" — combined with management's explicit acknowledgment that they are above the prior model — signals the structural re-rating is being absorbed by management as well as by the Street. Both Tim and Doug framed the demand environment as "as strong as I can remember" with multi-year visibility into CY27 fab openings.

1. CY26 WFE Raised to $140B "With Bias to the Upside"

"In January, we shared our outlook for 2026 WFE in the $135 billion range. Since then, spending projections from customers have moved higher across all device segments. We now expect WFE of $140 billion with a bias to the upside as the industry continues to work through various constraints. We believe this sets the stage for another year of compelling WFE growth in 2027." — Tim Archer, CEO

The CY26 WFE upward revision from $135B to $140B "bias up" is the second consecutive upward revision in the same calendar year (the original initial January estimate was $135B; whisper-Street had moved to $140-145B going into the print). The "compelling WFE growth in 2027" commentary is the first explicit CY27 directional commitment from management — a structural change from the Q2 call where CY27 was framed only as "pretty good year" in response to a specific analyst question. The "bias to the upside" framing implies management sees a $145B+ scenario as credible if more clean-room availability unlocks in H2-26.

Assessment: The CY26 +$5B raise + the CY27 "compelling growth" commitment together represent the strongest structural WFE framing from any of the WFE OEMs this cycle. The implied CY26-27 WFE growth trajectory ($110B → $140B+ → $150-160B) is materially above the historical 5-7% growth rate. The structural setup supports continued multi-year revenue compounding for Lam.

2. NAND $40B Conversion Pulled Forward to End-CY27

"As you may recall, we said in early 2025 that roughly $40 billion in conversion spending would be required over several years to enable existing NAND installed wafer capacity to produce devices with more than 200 layers. We now anticipate that this conversion will be pulled forward with the majority of spending occurring before the end of calendar year 2027. In parallel, we expect growth in bit demand will drive greenfield capacity investment, especially considering that overall industry installed wafer capacity is expected to decline more than 20% from prior highs by the end of this year." — Tim Archer, CEO

This is the single most material new disclosure of the print. The previous framing of "$40B over several years" was widely interpreted as a multi-year tail through CY28-30. The new framing of "majority before end-CY27" implies $20B+ of NAND conversion spending in CY26-27. Combined with the greenfield capacity additions needed to offset the 20%+ wafer-capacity decline as conversions reduce per-tool throughput, the NAND-segment outlook for Lam is structurally re-rated.

The economic logic is compelling: AI data centers need higher-capacity QLC NAND at >200 layers for SSD performance economics. Existing installed-base wafer capacity at <200 layers does not meet those economics, so conversions accelerate. The wafer capacity reduction creates a structural bit shortage that requires greenfield additions on top of conversions. Lam, with the largest 3D NAND installed base + leadership in high-aspect-ratio cryo etch, dielectric stack deposition, worldline metallization, backside stress management, and gap fill, captures both the conversion and greenfield spending.

Assessment: The NAND pull-forward is structurally the most asymmetric data point in the print for Lam-specific upside. The CY26-27 NAND revenue trajectory is likely $7-10B over the two years combined (vs the prior expectation of perhaps $5-6B). This is the new key catalyst for CY27 revenue acceleration.

3. June Q Guide $6.6B + GM 50.5% — Target Model Hit 4 Years Early

"We're expecting revenue of $6.6 billion, plus or minus $400 million. Gross margin of 50.5%, plus or minus 1 percentage point. We're expecting this expanding gross margin despite slight headwinds that we're seeing from customer mix. Forecasting operating margins of 36.5% plus or minus 1 percentage point. And finally, we're forecasting record earnings per share of $1.65, plus or minus $0.15." — Doug Bettinger, CFO

The June Q guide of $6.6B implies +13% sequential and +24% YoY growth — the largest sequential step-up of this cycle. Gross margin guide of 50.5% breaks the long-stated "above 50%" target model 4 years ahead of the original timeline. Operating margin guide of 36.5% materially exceeds the prior ">35%" long-term target. Management explicitly acknowledged the prior framework is now obsolete and committed to update "later in the year" — likely at an Investor Day or as part of a CY27 guidance discussion.

The CFO's instruction to "keep [gross margin] roughly in the levels we just guided you to in June" for the rest of the year is informal Q3-Q4 (Lam fiscal) gross margin guidance — implying 50% sustained through Q1 FY27 (Sep). The 36.5% operating margin guide demonstrates the embedded leverage as revenue ramps without proportional OpEx growth (despite the deliberate R&D + headcount increases).

Assessment: The June Q guide is the cleanest forward-acceleration signal of any of the four LRCX prints in this backfill arc. The +13% sequential + 50.5% gross margin + 36.5% operating margin + $1.65 EPS combination implies FY26 revenue trajectory of $23.5-24B (~+25% YoY from $18.4B FY25) and EPS of $5.85-6.10. The implied CY26 revenue is $23.8-24.5B (calendar basis) — comfortably above prior models.

4. Advanced Packaging Growth Raised to ">50% in CY26" (from ">40%")

"We see growing demand for our advanced packaging solutions where we bring unmatched experience in equipment design and process technology for copper plating and TSV etch. Lam's advanced packaging revenue growth is expected to exceed 50% in calendar year 2026." — Tim Archer, CEO

The advanced packaging growth outlook was raised from ">40%" at the Q2 call to ">50%" at Q3, a meaningful upward revision in just one quarter. The driver is the combination of HBM-related TSV etch + copper plating demand and the broader chiplet-style integration adoption across foundry/logic. The PECVD share-gain commentary specifically called out advanced packaging underfill as a key contributor, further evidence that the franchise extends beyond the HBM-direct categories into adjacent applications.

Assessment: +50% growth on a base we estimate at $3-3.5B = $1.5-1.75B incremental revenue contribution. The advanced packaging franchise is now structurally one of the highest-growth components of the Lam revenue mix, and the share-gain trajectory implies multi-year compounding beyond CY26.

5. SAM Share at "Slightly More Than Mid-30%s"; "Well On Track" to High-30%s

"In 2026, we see Lam's served available market or SAM, percent of WFE, expanding to slightly more than the mid-30s percent level, well on track towards our stated goal of high 30s percent over the next few years." — Tim Archer, CEO

The "slightly more than mid-30%s" framing represents incremental progress from the "mid-30%s" stated at the Q2 call (CY25 close). The multi-year north star of "high 30%s" — implied to be reached "over the next few years" — represents structural share gain that compounds beyond WFE growth. Each percentage point of SAM share at $140B+ WFE = $1.4B+ incremental Lam revenue, so the multi-year gain from mid-30%s to high-30%s could represent $4-6B of incremental SAM beyond the WFE growth contribution.

Assessment: The SAM expansion vector is structurally underpriced by the market. At current trajectory, Lam captures ~36% of CY26 $140B = ~$50B SAM; at high-30%s of CY27 $150-160B WFE = $55-62B SAM. The conversion of SAM to revenue is dependent on Lam's share-within-SAM, which remains an ongoing share-gain story.

6. First Dielectric Etch Wins at Key Foundry/Logic Customer

"Most notably, this quarter, we achieved both dielectric etch wins at a key founder logic manufacturer. Our first dielectric etch wins at this customer." — Tim Archer, CEO

This is a meaningful share-of-wallet expansion disclosure. Dielectric etch at leading-edge foundry/logic has historically been an area where Lam has lower share — the win at a "key" customer represents new revenue + the structural validation that the Vantex/Flex toolsets compete effectively at the leading edge. The CEO did not name the customer, but the framing of "key foundry/logic manufacturer" plus the dielectric etch category implies this is at the 2nm/A16 generation where competition is most intense.

Assessment: Dielectric etch share gain at a major foundry/logic customer is a multi-year revenue catalyst as the customer's node ramps. Initial win revenue is likely $100-300M in the qualifying year, scaling to $500M-1B+ as the production node ramps over 2-3 years. This is a structurally important win for the foundry franchise composition.

7. Equipment Intelligence + Dextro Cobot Commercial Traction

"Customers using Dextro and production are benefiting from higher output and in some cases, improved yield from existing capacity. In the March quarter, we expanded Dextro coverage to 8 Lam tool types up from 6 last quarter. We also introduced the next generation of Dextro, which packs 10x more compute power than the first generation into a smaller footprint." — Tim Archer, CEO

The Equipment Intelligence + Dextro cobot story progressed from "rollout" at the Q2 call to "commercial traction" at Q3 with specific customer-yield outcomes. The new foundry/logic Equipment Intelligence services agreement for critical deposition applications + a separate top-memory-customer R&D Equipment Intelligence deployment for NAND/DRAM new-node ramps demonstrate the offering is being adopted across both major customer cohorts. The Dextro tool-type expansion (6 → 8) + 10x compute upgrade + first deposition cobot in Q4 indicate accelerating product velocity.

Assessment: Equipment Intelligence + cobots are a structural CSBG growth lever that does not depend on new-fab capex. The recurring-services revenue + the productivity-share-of-wallet expansion combine to add multi-hundred-million-dollar opportunities across the 100K+ chamber installed base.

8. Capital Return Discipline — 139% FCF Return + $750M Notes Retired

Capital return in Q3 was structurally aggressive: $800M buyback at avg $211/share (including a $200M ASR) + $326M dividends + $750M unsecured notes retirement = 139% of free cash flow returned. The notes retirement reflects the previously-disclosed paydown plan; the buyback at $211 average is materially above the Q2 average of $154/share, indicating management's view on intrinsic value at higher absolute price levels. Cash declined to $4.8B from $6.2B; $4.3B of buyback authorization remains.

The CFO's commitment to return "at least 85% of free cash flow to our shareholders over time" — with current trailing return well above that — implies the buyback pace can moderate in coming quarters as cash rebuilds from FCF generation. The free cash flow generation at the new revenue scale is structurally supportive: at $24B FY26 revenue + 35%+ operating margin + ~9% tax rate + ~$1.3B capex = ~$6.5-7B FY26 FCF, of which 85%+ = $5.5-6B returned.

Assessment: Capital return remains a multi-year tailwind to EPS via share count reduction. The $4.3B buyback authorization at current pace implies 6-8 quarters of incremental buyback runway before re-authorization.

9. Long-Term Model Update "Later in the Year"

"We're talking internally about the fact that we're above the previous model that we gave. And yes, I know we need to give you an updated framework and we will do that later in the year. And we haven't bottomed out on exactly when or exactly how we're going to do it, but we know we need to and we will be doing that." — Doug Bettinger, CFO

This is a structural re-rating catalyst telegraph. The current "above 50% gross margin" + "above 35% operating margin" long-term model is being breached in real time. The promised update "later in the year" — combined with the CY27 "compelling growth" framing — sets up either an Investor Day or a CY27-guide event as a near-term re-rating catalyst. The market typically rewards explicit long-term-model updates with multiple-expansion when the prior model is clearly breached.

Assessment: The framework-update event in H2 CY26 is a high-probability re-rating catalyst. We expect the updated long-term model to land at "above 51-52% gross margin / above 37% operating margin / CY27 revenue $26B+" framing.

10. Demand Environment "As Strong as I Can Remember"

"Demand has always been there. Demand is as strong as I can remember it. Frankly, it was strong 90 days ago. It continues to be maybe even a little bit stronger right now, and everybody found a little bit more clean room and so they were able to take a little bit more equipment." — Doug Bettinger, CFO

The CFO has been at Lam since 2013; "as strong as I can remember" covers 12+ years of WFE cycles including the prior peak years (2018, 2022). The structural framing is that demand is uniform across customer segments — "everything is just a little bit stronger" — which is the inverse of the historical cyclical pattern where one or two segments lead. Clean-room availability remains the binding constraint, not demand.

Assessment: The demand-strength qualitative framing is unusually unambiguous. Combined with the structural CY27 commitment, this is a multi-year setup rather than a cyclical peak.

11. Workforce Optimization Alongside Growth

Headcount increased +900 sequentially to ~20,600 (up from ~19,700 in Q2), primarily within manufacturing, field organizations, and R&D. Concurrently, Lam executed a "small workforce optimization focused on efficiency" — visible in the non-GAAP reconciliation. The simultaneous expansion (+900) and efficiency action signals that the company is selectively re-shaping the workforce composition rather than reducing total scale. The Malaysia 2nd manufacturing facility coming online H2-CY26 (approximately the same size as the first ~700K sq ft facility) supports the manufacturing headcount expansion.

Assessment: The workforce re-composition demonstrates discipline on margin maintenance alongside growth investment. Operating margin guide of 36.5% June validates the leverage path.

Guidance & Outlook

Implied FY26 Trajectory: H1 FY26 actuals (Sep $5.32B + Dec $5.34B) = $10.66B; Mar $5.84B + Jun $6.6B (mid) = $12.44B H2 FY26. Total FY26 revenue ~$23.1B (+26% YoY from FY25 $18.4B), with bias up if June Q lands at the high end of the $6.6B ± $400M range. FY26 non-GAAP EPS likely $5.85-6.10. The H2-26 weighted year called out at the Q2 call is materializing: H2 FY26 (Mar + Jun) of $12.4B is materially above H1 FY26's $10.7B.

Analyst Q&A Highlights

Gross Margin Pace + Capacity Plans

The opening question on the call sought to deconstruct the rapid gross margin expansion and the implied operating-model breach. The CFO walked through the multi-year drivers — manufacturing footprint proximity to customers, factory efficiencies, pricing for value — while signaling that the levels just guided are the new operating regime for the remainder of the calendar year. The CEO added that the focus on tool maturity at field deployment reduces installation and warranty cost, flowing directly to gross margin.

Q: "Doug, I wanted to ask about gross margin. The guidance is great, it's 50.5%. It sounds like despite the mix being against you. So you're kind of already edge at your target model, right, because you were saying above 50. And I'm not asking you to update that model. But sort of can you like deconstruct how you got here so fast?"
— Timothy Arcuri, UBS

A: "It's been a lot of real hard work from the company, honestly. I think you'll remember, 4, 5 years ago, we talked about expanding our factory footprint to be closer to where our customers were. And that has delivered efficiencies from just a proximity standpoint, from shorter frame logistic lanes. From slightly lower cost from a labor standpoint, a better supply chain set up all of those things. Those were self-help activities that we undertook and frankly, we've delivered on it... I would encourage you to kind of keep it roughly in the levels that we just guided you to in June. This is going to kind of level out at where it's at, I think, for the rest of the year."
— Doug Bettinger, CFO

Assessment: The "level out at June levels" framing is informal Q1 FY27 (Sep) gross-margin guidance at ~50.5%. The structural driver attribution (footprint + tool maturity + pricing for value) is multi-year and not cyclical, supporting durability of the new gross margin regime through cycle transitions. The framework-update commitment "later in the year" sets up the formal re-rating event.

CY27 Visibility + Supply Chain Readiness

The CY27 visibility question pressed management on whether the conversations with customers have moved beyond an 18-24 month window. The CEO confirmed that with mid-2026 already in view, customer conversations now extend into CY27 fab openings, with engineering resource planning conversations extending even further. The CFO added the explicit "good year in 2027" framing.

Q: "I just wanted to touch on your commentary around '27 visibility. And can you kind of speak to your discussions, conversations exceeding 18, 24 months, whether you're starting to see real slotting and desire to lock in time frames for delivery? And I guess as part of that, how are you kind of working your supply chain for readiness for that ramp?"
— Christopher Muse, Cantor Fitzgerald

A: "We're about halfway through '26. And so given our lead times, of course, we're having conversations with customers about '27. And in some cases, for planning purposes, like getting resources ready engineers hired and trained in the right locations, those — some of those conversations even extend beyond that... We're working a lot with customers on near-term constraints, things they can do within their existing fabs. But at the same time, preparing for those new fab openings and true kind of greenfield shipments as they roll out later this year and through next year."
— Timothy Archer, CEO

"It feels like it's setting up to be a pretty good year in '27 right now based on what we can see."
— Doug Bettinger, CFO

Assessment: The CY27 visibility framing is materially firmer than at the Q2 call (where CY27 was framed as "pretty good year" in response to an analyst-specific question). The mid-CY26 conversations + engineering-resource-planning extension imply CY27 customer commitments are advancing on the typical 18-24 month lead-time pattern. Management's willingness to use "compelling growth" and "good year" language for CY27 is a meaningful directional commitment.

NAND Market Dynamics — Pull-Forward Reasoning

The NAND question pressed on what has changed in 90 days to support both the pull-forward of the $40B conversion and the growth-through-the-year framing. The CEO walked through the AI memory hierarchy thesis — data-center bits exceeding PC + mobile, QLC + >200-layer required for AI economics, installed-base under-investment over the prior period.

Q: "My question is on the NAND market. It seems like near-term NAND is still low, like 12% sales, but something has changed versus 90 days ago, you guys are talking about NAND growing through the year and the pull forward in that the $40 billion number. So can you describe what has changed in the NAND market?"
— Atif Malik, Citi

A: "There is increased demand for NAND coming from AI data centers, and that's helpful. But also, if you think of the on a relative basis, what under investment in that area, partly as customers make choices about clean room allocation and obviously some other devices like HBM were so hot during that period. Also, going back to what we said early last year, the installed base had gotten a little bit behind in terms of the state-of-the-art technology. And so most of the installed base at that time, early 2025, about 2/3 of it was still running in the 1xx 100-plus layer technologies really when you need to get those incremental bits out now, you need to be 200-layer plus. And so that's what's caused this acceleration is you need more bits. You need those bits to be more capable, you need QLC to meet AI data center demands and so you've started to see the push for accelerated conversions in the technology."
— Timothy Archer, CEO

Assessment: The NAND acceleration logic is structurally compelling: AI inference + data-center NAND demand exceeds installed-base capability + clean-room-allocation choices in CY24-25 created under-investment in NAND while HBM scaled = a sharper-than-expected conversion cycle now front-loaded into CY26-27. This is the highest-conviction CY26-27 upside vector for Lam-specific outperformance.

OpEx Trajectory + Long-Term Model Update Timing

The question on OpEx growth and the operating-margin model breach gave management an opportunity to commit to the model update event. The CFO confirmed the model needs to be updated, framed the spending discipline ("top line growing faster than spending"), and committed to deliver "later in the year."

Q: "Your OpEx grew 5% sequentially in the March quarter, implied OpEx growth in June is 7% and given the leverage, it's allowing you to actually exceed your long-term operating margin target of 35%. So how should we think about the OpEx growth through the remainder of this year? And I guess when is the team going to update its long-term targets?"
— Harlan Sur, JPMorgan

A: "At the end of the day, this management team likes to see the top line growing faster than spending so that we can deliver leverage and that's absolutely how we're thinking about things this year. Having said that, we're going to grow spending this year because, frankly, we can afford to do so, and we have some things that I think are quite innovative that we've been thinking about that we've wanted to put a little more money towards. So we're going to do that. We've decided we're going to do that this year. And yes, we're talking internally about the fact that we're above the previous model that we gave. And yes, I know we need to give you an updated framework and we will do that later in the year."
— Doug Bettinger, CFO

Assessment: The framework-update commitment is the most important structural-catalyst telegraph of the call. We expect the updated long-term model (likely H2 CY26) to land at ~51-52% gross margin / ~37% operating margin / CY27 revenue $26B+ — a multi-bp re-rating event when delivered.

Memory Cycle Sustainability — "The D-Word"

The question on whether the current memory cycle differs from prior cycles touched the structural-vs-cyclical debate. The CEO offered the Lam-specific framing — etch + dep intensity scaling creates SAM expansion + share gain that outperforms underlying memory cycles. The CFO offered "disciplined investment" as the differentiator on this cycle vs prior episodes.

Q: "I had a more thematic question maybe for Tim or Doug. We've heard a lot of about reasons why this memory cycle is different with HBM and trade ratios and new applications like SOC and it does seem like AI is driving memory demand growth a lot faster than what we've seen historically. So I guess, do you ascribe to the view that this memory cycle is — I won't say the D-word, but there's a change this time around? And then what kind of actions are you taking to derisk the cyclical side of things while still being able to capture the upside?"
— Melissa Weathers, Deutsche Bank

A: "I think it's different for Lam in that — the most important thing about this memory cycle is it is a cycle in which you're seeing dramatic improvement and change in the etch and dep intensity. And so the complexity of 3D scaling has created a lot of new opportunities for Lam. And so that is driving both SAM expansion plus share gain for us through those new applications. So I feel like compared to prior upturns in memory, we are and we're doing even better just because of that extra layer of etch and dep intensity scaling."
— Timothy Archer, CEO

"Disciplined investment, right? I mean, everybody likes profitability that they're generating right now. Everybody is just kind of lugging into where demand is."
— Doug Bettinger, CFO

Assessment: The "different for Lam" framing reframes the cyclical-memory question as a structural-mix question. The etch+dep intensity scaling at every node creates structural SAM expansion + share gain that compounds even through cyclical memory cycles. The CFO's "disciplined investment" framing is the cycle-level argument: customers are not over-building.

Sustainability of Pricing + Margin in a Cycle Downturn Scenario

Vivek Arya pressed on whether the 50.5% gross margin is durable through a hypothetical memory pricing downturn. The CEO declined a specific forecast but offered the structural framing that the margin improvement is rooted in value delivery and operational efficiency rather than transactional pricing.

Q: "Maybe the subtext of my question is the gross margins that you're seeing, right, the 50.5%, how durable are there? So let's say if memory pricing goes down next year for whatever reason, do you still think these gross margins are sustainable? And maybe you can even expand from these?"
— Vivek Arya, Bank of America

A: "We have been building the gross margin improvement in our company around fundamental capabilities, either our own through our own operational efficiency or through the value that our equipment delivers... we have moved at a pace where we feel like the improvements we're making are sustainable because they're rooted in real value or real efficiency. And they're not — they're not leveraging sort of the opportunity, and they're not transactional in nature."
— Timothy Archer, CEO

Assessment: The "rooted in real value or real efficiency, not transactional" framing is a structural durability claim. If memory pricing declines but Lam's tool sets deliver productivity/yield value, the pricing is durable through customer-pressure cycles. We model gross margin durability at 49-51% range through cycle scenarios.

CSBG Sustainability + Acceleration

The CSBG question explored whether the $2B+ quarter is repeatable and whether services growth can accelerate. The CFO walked through the utilization-driven framework (spares/service driven by industry utilization, which is "very, very high" and unlikely to get higher); the upgrade growth contribution; and the Equipment Intelligence/cobot acceleration layer on top.

Q: "It does seem like the clean room issue is not going to get resolved. Demand is very strong. So my question is, should we — are you seeing any acceleration in terms of your services and spares business? Is this something structural in your view going forward?"
— Srinivas Pajjuri, RBC Capital Markets

A: "What drives a lot of spares and service, frankly, is utilization in the overall industry. Utilization right now and in the March quarter, is very, very high. And so a lot of the growth at least contributing to some of the sequential growth in CSBG was the uptick in spares and service from that utilization. I don't know that utilization can get any higher than it is. Frankly, it's pretty full out right now. And so when you think about growth sequentially over the next couple of quarters, those components of CSBG are probably kind of plus or minus where they are. Now Tim talked about advanced service and cobots and EI, that layers on top of that to a certain extent."
— Doug Bettinger, CFO

Assessment: The CSBG framework is informally guided to sustain ~$2.1B/quarter (~$8.4B annualized) through the remaining CY26 quarters, with upside from Equipment Intelligence and cobot adoption. We model FY27 CSBG at $8.5-9.0B with cobot/EI providing the incremental growth lever above baseline utilization.

What They're NOT Saying

1. CY27 WFE specific dollar framework: "Compelling growth" qualitative only; no $ range. Reading between lines: implies $150-160B credible scenario.
2. NAND $40B conversion period dollar pacing: "Majority before end-CY27" — but CY26 vs CY27 split not quantified.
3. Specific customer for dielectric etch win: "Key foundry/logic manufacturer" — undisclosed. Best inference: TSMC at N2/A16 or Samsung at 2nm.
4. Updated long-term operating-margin model: Committed "later in the year" but specific value (51%? 37%?) undisclosed.
5. Advanced packaging dollar contribution: >50% growth disclosed but base size not provided.
6. Stryker SiOC dielectric ALD specific revenue: "Tool of record at all leading memory makers for bitline spacer" but no $ contribution.
7. HBF (High Bandwidth Flash) timing: Customer-specific timing deferred to customer disclosures; Lam SAM framing only.
8. Malaysia 2nd facility revenue capacity: Same size as first (~700K sq ft) but no specific revenue capacity number.

Market Reaction

• Pre-print (Apr 21): $258.37, +10.7% from Q2 print T+2. Orderly grind into the print on whisper-Street CY26 WFE $140-145B already crept above the formal $135B guide.
• Day-of (Apr 22): Close $265.55 (+2.78%). Pre-print strength on industry-wide CY26 WFE upward bias.
• T+1 (Apr 23): Gap up to ATH $272.82 intraday, then sustained selling. Close $258.56 (-2.63%). Classic profit-taking after the print.
• T+2 (Apr 24): Close $267.78 (+3.57%). Dip-buying validates structural thesis.
• Net cumulative print to T+2: +0.84% on 32M shares volume.
• Sell-side: Multiple PT raises (3rd consecutive quarter); no upgrades to outperform from already-rated houses; no downgrades. CY27 visibility + GM target hit 4 years early cited as standouts.

The muted +0.84% net move despite the magnitude of the structural beat reflects that the thesis is now largely embedded in the price. The +57% post-Q1 run + +10.7% Q2-trough-to-Q3-pre-print rally combined had already priced the upward CY26 WFE revision. The genuine surprise that the market is processing is the NAND $40B pull-forward — which is more difficult to model quickly than the WFE-level revisions. The 32M shares of volume across T+1+T+2 indicates meaningful institutional positioning churn — buyers absorbing the profit-taking from earlier holders.

Street Perspective

Debate: Is the CY27 "compelling growth" framing $150B or $160B?

Bull view: Clean-room constraints unlock H2-CY26 + multi-year fab openings + NAND $40B conversion majority CY27 + advanced packaging compounding = $155-165B CY27 WFE. Lam's SAM share at high-30%s on a $160B base = $58B+ Lam SAM, with conversion to revenue at high share-within-SAM = $26-28B FY27 revenue.

Bear view: "Compelling growth" deliberately vague; could mean $145-150B if H2-26 pull-in is timing-shift rather than incremental. Memory cycle peak risk (Melissa Weathers' "D-word" question) caps CY27 enthusiasm. Lead-time signals (lead times "stretching out a little bit") could foreshadow demand normalization.

Our take: The CFO's "pretty good year" + "compelling growth" framing implies CY27 WFE +10-15% on the CY26 $140B base = $155-160B. With NAND conversion pull-forward concentrated H2-26 and CY27, plus continued advanced packaging compounding, the CY27 WFE is structurally constructive. We model CY27 WFE at $155-160B and Lam FY27 revenue at $26-28B.

Debate: Does the GM 50.5% target-model breach drive multi-year multiple expansion?

Bull view: Reaching the long-stated gross-margin target 4 years early + the explicit framework-update commitment "later in the year" + sustained 50%+ gross margin guidance through CY26 = re-rating event imminent. The combined 51-52% GM / 37% Op / CY27 $26B+ updated model would re-rate LRCX from current 27x forward EPS to 30-33x.

Bear view: Gross margin durability through cyclical scenarios untested. The "rooted in value" framing is management commentary, not empirically demonstrated through a memory pricing downturn. Multiple expansion requires the cycle to extend without a peak.

Our take: The model update is a high-probability re-rating catalyst. We assume modest multiple expansion (27x → 29-30x forward EPS) on framework formalization. Fair value $285-320.

Debate: Is the +$0.84% net reaction a thesis-embedded confirmation or a structural-fatigue signal?

Bull view: Thesis embedded = the structural narrative is now consensus. The cycle-extension/SAM-expansion combination supports continued multi-quarter compounding without requiring incremental positive surprises.

Bear view: Without further structural-positive surprises, the multiple compression risk on any cycle softness exceeds the multiple-expansion potential on continued growth. The risk-reward is asymmetric to the downside at current levels.

Our take: The thesis is largely embedded but the framework-update catalyst remains. We maintain Outperform with conservative position sizing (3-5%) and recognize that future re-rating requires either CY27 quantification (likely H2 CY26) or a step-function structural surprise (HBF ramp, share-of-wallet step-up at a specific customer).

Model Update Needed

Valuation impact: At April 24 close of $267.78 and ~1.255B diluted shares, market cap is ~$336B; net cash ~$2B; EV ~$334B. On FY27E revenue $27B and non-GAAP EPS $7.05, LRCX trades at 12.4x EV/Sales and 38x EV/EPS. Our 12-month fair-value range: $285-320 (6-20% above April 24 close), supported by (a) framework-update re-rating catalyst, (b) NAND conversion pull-forward providing incremental FY27 revenue contribution, (c) advanced packaging +50% CY26 growth compounding into CY27, (d) CY27 WFE "compelling growth" commitment.

Thesis Scorecard Post-Earnings

Action: Maintaining Outperform. The structural thesis is comprehensively validated by the Q3 print + CY26 WFE +$5B raise + CY27 commitment + NAND pull-forward + GM target hit 4 years early. Position sizing 3-5% reflects multi-year conviction tempered by cycle-late absolute valuation. Re-rate to high Outperform on (a) successful framework update event (likely H2 CY26), (b) CY27 WFE quantification, or (c) HBF ramp commercialization signal. Re-rate down to Hold on (a) memory cycle peak signal (DRAM/HBM pricing reversal), (b) lead-time normalization indicating demand softening, or (c) CY27 WFE framework softer than "compelling growth" implies.
