# Lam Research Corporation (LRCX) — Narrative, FY2026 Q3 Fiscal Q3 2026 ended March 29, 2026. Lam's fiscal year ends in late June; fiscal 2025 ended June 29, 2025. Sources: Annual Report on Form 10-K for fiscal year 2025, accession 0000707549-25-000075; Quarterly Report on Form 10-Q for the quarter ended March 29, 2026, accession 0000707549-26-000022; Current Reports on Form 8-K, accessions 0000707549-26-000020 (April 22, 2026 results and outlook), 0000707549-26-000012 and 0000707549-26-000014 (February 2026 board and management changes), and 0000707549-25-000094 (November 2025 annual meeting). --- ## Business *From the FY2025 10-K, accession 0000707549-25-000075.* Lam Research was incorporated in 1980, is a Delaware corporation, and is headquartered in Fremont, California. It is a global supplier of wafer fabrication equipment and services to the semiconductor industry, with core competencies in nanoscale manufacturing enablement, chemistry, plasma and fluidics, and advanced systems engineering. The company operates in **one reportable business segment**: manufacturing and servicing of wafer processing semiconductor manufacturing equipment. **Where the money comes from.** Lam sells into three process domains — deposition, etch, and clean — plus an aftermarket business: - **Deposition.** ALTUS (tungsten/molybdenum CVD+ALD for contacts, vias, wordlines; ALTUS Halo for selective/conformal metallization); SABRE (electrochemical copper deposition and damascene, cobalt for logic; SABRE 3D for advanced-packaging bumps, redistribution layers, TSV fill, wafer-level bonding including HBM); SPEED (HDP-CVD dielectric gapfill); Striker (single-wafer dielectric ALD for low-k spacers, high-aspect-ratio gapfill, spacer-based multiple patterning); VECTOR (PECVD dielectric films). - **Etch.** Flex (dielectric etch, multi-frequency confined plasma); Vantex (dielectric etch on the Sense.i platform, aimed primarily at 3D NAND high-aspect-ratio holes, trenches, contacts and capacitor cells); Kiyo (conductor etch with proprietary Hydra CD-uniformity technology); Syndion (deep silicon etch — CIS trenches, power devices, TSVs for HBM and advanced packaging); Versys Metal (metal etch and hardmask). - **Clean.** Coronus (plasma bevel clean with active die-area protection); DV-Prime, Da Vinci, EOS and SP Series (single-wafer spin wet clean and wet etch, including backside thinning for power devices, MEMS and image sensors). - **Customer Support Business Group (CSBG).** Service, spares, upgrades, Equipment Intelligence fleet software, and the **Reliant** line of new and refurbished non-leading-edge deposition, etch and clean tools. Upgrades let customers extend existing fab lines rather than buy new systems. In fiscal 2025 this and other non-systems revenue was **$6.94 billion of $18.44 billion total** (systems: $11.49 billion). Lam also serves back-end wafer-level packaging, including fan-out panel-level packaging and 3D stacking for high bandwidth memory, plus adjacent markets that use semiconductor processes (CMOS image sensors, MEMS). **Customers and concentration.** The customer base is leading memory, foundry and integrated device manufacturers making NVM, DRAM and logic. In fiscal 2025 two customers accounted for approximately **17% and 15%** of total revenue (one customer at ~17% in fiscal 2024; two at ~22% and ~16% in fiscal 2023). The most significant customers across fiscal 2023–2025 were **Samsung Electronics** and **Taiwan Semiconductor Manufacturing Company**. Systems can be priced up to tens of millions of dollars each, so the timing of a handful of tool acceptances moves a quarter. **Geography.** Non-U.S. sales were approximately **93% of revenue in fiscal 2025**, 93% in 2024 and 91% in 2023. Lam reports across seven regions: United States, China, Europe, Japan, Korea, Southeast Asia, Taiwan. Fiscal 2025 mix: China 34%, Korea 22%, Taiwan 19%, Japan 10%, U.S. 7%, Southeast Asia 5%, Europe 3%. Long-lived assets totaled $2.72 billion at fiscal year-end 2025, with $1.72 billion in the United States. **Manufacturing.** Operations mainly assemble and test components, sub-assemblies and modules into finished systems, largely in cleanrooms, with meaningful outsourcing of manufacturing, production warehousing and logistics. Certain components and sub-assemblies come from a **single supplier**; Lam qualifies alternates where practical and at times carries inventory above current need. **Competition.** Applied Materials is the primary competitor in dielectric and metals deposition; ASM International and Wonik IPS in ALD and PECVD; Applied Materials, Hitachi and Tokyo Electron in etch; Screen Holdings, Semes and Tokyo Electron in wet clean. The structural feature that matters is qualification lock-in: once a manufacturer qualifies a supplier's tool for a production application and technology node, it generally stays with that supplier for as long as the tool performs to spec — which protects Lam's installed base and equally blocks it where a competitor won first. **People.** Approximately **19,000 regular full-time employees** as of August 7, 2025 — over 29% in research and development; approximately 43% in the United States, 50% in Asia, 7% in Europe. (Headcount was approximately 20,600 as of March 29, 2026.) **Capital structure note.** Lam effected a **ten-for-one stock split** on October 2, 2024; all per-share figures here reflect the split. --- ## Risk factors *Condensed from Item 1A of the FY2025 10-K, accession 0000707549-25-000075, as updated in the Q3 FY2026 10-Q, accession 0000707549-26-000022. The two sets of risk factors are substantively the same.* **Industry and customer** - **Cyclicality and resource allocation.** Semiconductor capital equipment demand changes rapidly. Because many of Lam's technology programs are multi-year commitments, management must size supply chain, workforce and facilities against a demand picture that can invert. Expand too fast and excess fixed costs remain; too slowly and share is lost. Downturns can bring receivable and inventory reserves, deferred-tax valuation allowances, restructuring charges, goodwill and long-lived asset impairments, and supplier claims for inventory ordered against orders that never arrived. - **Customer concentration.** A limited number of large customers drive a significant portion of shipments, revenue, cash flow and profitability. Large customers can negotiate pricing and terms, limit technology sharing, and concentrate credit risk. - **Qualification lock-in works both ways.** Once a customer qualifies a competitor's tool for a production line application, displacing it is difficult. - **Technology change.** Lithographic shrink — the industry's primary advancement driver for 25+ years — may be approaching its limit, pushing manufacturers toward more complex multi-technology changes. Betting on the wrong technology path, or failing to commercialize on time, means lost share, obsolete inventory and stranded R&D. A shift in process flows that requires *fewer* steps using Lam's products would hurt Lam more than less concentrated competitors. - **Customer consolidation and strategic alliances** can standardize a competitor's tool set for a given process step, shrink the total equipment market through scale economies, or shift pricing and IP control toward customers. **Business and operational** - **Result variability.** Revenue and margin swing on customer order timing, acceptances, deferred revenue movements, product and customer mix, FX, procurement shortages, supplier and outsource-provider failure, and legal/tax/regulatory change including export restrictions and tariffs. - **International exposure and trade policy.** With ~93% of revenue outside the United States, Lam is exposed to trade disputes, tariffs, export controls, localization demands (locally sourced systems, spares and services; pressure to partner with local firms and transfer IP), differing IP enforcement, and retaliatory action. Broad U.S. export controls may cause customers with international operations to reconsider reliance on Lam's products, strengthening competitors not subject to those controls. FX exposure is primarily yen-denominated revenue and euro, Korean won, Malaysian ringgit and Indian rupee expenses; hedges can leave the company over- or under-hedged and can forfeit favorable moves. Because most cash is generated offshore while buybacks, dividends and note repayments generally require onshore cash, cash geography constrains capital allocation. - **Supply chain and single-source parts.** Some key parts have long lead times or one qualified supplier. Costs and availability are exposed to tariffs, inflation, transportation interruption and export approvals. Restrictions on **PFAS** — widely used in parts and materials in Lam's products — could force substitution with no assurance suitable replacements exist at similar cost, or at all. - **Concentrated facilities.** Manufacturing and R&D sit in a limited number of locations, exposed to earthquake, wildfire, flood, heat, utility interruption, unrest and IT disruption. - **Product concentration.** A substantial share of revenue comes from a limited number of products; a narrow line can also make Lam look less strategically important to customers than broader-line competitors. - **IP protection and talent.** Patents run roughly one to twenty years and are selectively filed by jurisdiction; trade secret loss, non-issuance and weaker foreign enforcement are all live. Competition for engineering talent is intense and cyclical hiring/reduction cycles complicate retention. - **Cybersecurity.** Lam states it experiences cybersecurity threats and incidents in the ordinary course; past incidents have not been material, but future losses could be. Hiring cybersecurity talent has been and may remain difficult. - **Acquisitions and dispositions** may not be available for regulatory or other reasons, forcing reliance on joint development and collaboration that carries its own IP-sharing and value-sharing problems and lacks an acquisition's synergies. **Legal, regulatory and tax** - **China.** The single most specific named risk. China revenue — global customers plus domestic Chinese customers with China facilities — was approximately **34% of total revenue in fiscal 2025, 42% in 2024 and 26% in 2023**. U.S. rules have expanded export license requirements, added Chinese companies to restricted entity and unverified lists, restricted service and transfer at customer facilities engaged in certain end-uses, and extended the foreign direct product rule to Huawei-linked transactions. Licenses may not be granted timely or at all; further Commerce Department action could expand requirements. Lam states this has already limited its market, adversely affected revenue, and increased exposure to foreign competition. - **Environmental.** Handling, discharge, sale and disposal of hazardous substances — with PFAS regulation specifically called out — could require altered operations, added equipment, fines or remediation. - **IP and indemnity claims.** Infringement, misappropriation, product liability and contract claims; officer/director and customer/supplier indemnity obligations; insurance may not cover full losses. - **Tax.** Effective rate depends heavily on the geographic split of earnings; U.S.-heavy deferred tax assets depend on generating future U.S. taxable income. **BEPS 2.0** global minimum tax adoption across jurisdictions could materially affect the effective rate. - **Delaware exclusive forum.** The bylaws designate the Delaware Court of Chancery as sole forum for certain stockholder claims, which may discourage such suits. **Financial, accounting and capital markets** - **Leverage.** $4.5 billion aggregate principal of senior unsecured notes outstanding at fiscal 2025 year-end, plus a commercial paper program and a $2.0 billion revolving credit facility backstopping it (expandable by $750 million to $2.75 billion). Debt service diverts cash from operations, working capital, capex and acquisitions, and can impair future financing. - **Covenants** in credit agreements restrict additional debt, liens, affiliate transactions, changing the nature of the business, asset sales and mergers; breach could trigger acceleration. - **Dividends and buybacks are not assured.** Quarterly dividends have been declared since April 2014, but continuation depends on capital availability, board determination, covenants, onshore cash availability and tax law. Reduction or suspension could hurt the stock. - **Goodwill and long-lived asset impairment** risk if industry or economic trends, cash flow estimates or the company's own stock price deteriorate. - **Stock price volatility** — historically significant, tied in part to semiconductor prices and markets — and the securities class action exposure that tends to follow it. - **Counterparty risk** from derivative counterparties and from cash and investments held at banks in and outside the United States. --- ## Management's discussion and analysis — fiscal year 2025 *From the FY2025 10-K, accession 0000707549-25-000075. Fiscal 2025 ended June 29, 2025; fiscal 2024 ended June 30, 2024; fiscal 2023 ended June 25, 2023.* **Headline results** | | FY2025 | FY2024 | FY2023 | |---|---|---|---| | Revenue | $18,435.6M | $14,905.4M | $17,428.5M | | Gross margin | $8,979.1M (48.7%) | $7,052.8M (47.3%) | $7,776.9M (44.6%) | | Total operating expenses | $3,078.1M | $2,788.9M | $2,602.1M | | Net income | $5,358.2M | $3,827.8M | $4,510.9M | | Diluted EPS | $4.15 | $2.90 | $3.32 | Revenue rose **23.7%** in fiscal 2025 on strong equipment demand across memory and foundry plus higher customer support revenue for upgrades, spares and services. Gross margin expanded 140 bps on improved factory efficiencies and favorable product mix, partly offset by increased transformational charges. Operating expenses rose 10.4% on higher employee-related costs from increased headcount, transformational activity spend and higher outside services. Fiscal 2024's 14.5% revenue decline came primarily from non-volatile memory weakness, partly offset by DRAM strength and higher China regional revenue. **Composition of fiscal 2025 revenue.** Systems $11,491.3M; customer support-related and other $6,944.3M. By market: **Foundry 45%, Memory 42%, Logic/IDM 13%** (fiscal 2024: 40/42/18; fiscal 2023: 38/42/20). By region: China 34%, Korea 22%, Taiwan 19%, Japan 10%, U.S. 7%, Southeast Asia 5%, Europe 3%. **Deferred revenue** rose to **$2.7 billion** at fiscal 2025 year-end from $1.6 billion, primarily on higher advance deposits from newer customers. **Operating expense detail.** R&D $2,096.4M (11.4% of revenue, up 10.2%), driven by $118M more employee-related cost on higher headcount and $35M higher outside services including transformational and lab activity. SG&A $981.7M (5.3% of revenue, up 13.1%), driven by $112M more employee-related cost. **No restructuring charges in fiscal 2025** ($61.6M in 2024, $120.3M in 2023); the fiscal 2023 plan terminated approximately 1,760 employees and was substantially complete as of June 30, 2024, with cumulative cost of $181.9M. **Other income (expense).** Interest income $231.3M (down 8.2%); interest expense $178.2M; deferred compensation plan gains $39.1M; FX losses $26.4M. **Taxes.** The effective rate fell in fiscal 2025, primarily on recognition of previously unrecognized tax benefits from statute lapses and the mix of income across jurisdictions. Gross deferred tax assets were $1,897M (from $1,516M), offset by $197M of gross deferred tax liabilities and a **$424M valuation allowance** representing essentially the entire California deferred tax asset balance. The **One Big Beautiful Bill Act** was signed July 4, 2025 — after fiscal 2025 year-end — so its effects, including changes to the taxation of non-U.S. income, land in fiscal 2026. **Liquidity and capital allocation.** Cash, cash equivalents and restricted cash of **$6.4 billion** at fiscal 2025 year-end versus $5.9 billion. Operating cash flow **$6.2 billion** (versus $4.7 billion). Uses: **$3.4 billion of treasury stock purchases** including net share settlement of stock-based compensation, **$1.1 billion of dividends**, **$759 million of capital expenditures**, and $507 million of principal payments and debt issuance costs. Working capital sources included a $1.1 billion increase in deferred gross profit; uses included an $859 million increase in accounts receivable. **Debt actions during fiscal 2025.** $500 million of 2025 Notes settled at maturity in March 2025 from cash on hand. In January 2025 Lam entered a Third Amended and Restated Credit Agreement, raising the unsecured revolver from $1.5 billion to **$2.0 billion** and extending maturity from June 2026 to **January 2030**, with a $750 million expansion option to a potential $2.75 billion. At fiscal year-end, **$4.5 billion principal** of fixed-rate long-term debt was outstanding with a fair value of $3.9 billion. Cancellable open purchase order commitments expected to be fulfilled within one year were approximately $387 million. **Management's framing of the cycle.** Wafer fabrication equipment spending was strong in fiscal 2025 across memory and non-memory. Near term, management flags trade restrictions and tariffs as a negative on revenue and operating margin. Longer term, it argues secular semiconductor demand plus technology inflections — 3D device scaling, multiple patterning, process flow, advanced packaging chip integration — expand Lam's served available market in deposition, etch and clean. Management also notes it exercises discretion over the timing and prioritization of manufacturing and deliveries, which has affected and may affect when revenue is recognized. --- ## Current quarter — fiscal Q3 2026 (quarter ended March 29, 2026) *From the 10-Q, accession 0000707549-26-000022, and the results release furnished on Form 8-K, accession 0000707549-26-000020.* **Results** | | Q3 FY26 (Mar 2026 qtr) | Q2 FY26 (Dec 2025 qtr) | Q3 FY25 (Mar 2025 qtr) | |---|---|---|---| | Revenue | $5,841.5M | $5,344.8M | $4,720.2M | | Gross margin | $2,910.5M (49.8%) | $2,651.2M (49.6%) | $2,313.7M | | R&D | $583.2M (10.0%) | $573.3M (10.7%) | $525.9M | | SG&A | $280.3M | $267.7M | $226.0M | | Operating income | $2,047.0M (35.0% margin) | — (33.9% margin) | $1,561.8M | | Net income | $1,825.5M | $1,594.0M | $1,330.7M | | Diluted EPS | $1.45 | $1.26 | $1.03 | Nine months ended March 29, 2026: revenue **$16,510.5M** (versus $13,264.2M), gross margin **49.9%** (versus 48.2%), R&D $1,733.0M, SG&A $827.3M, net income **$4,988.1M**, diluted EPS **$3.95** (versus $2.81). **What drove the quarter.** Revenue rose 9% sequentially on higher systems revenue from **increased DRAM investment**, plus higher customer support revenue from an expanding installed base and higher spares, upgrades and services — partly offset by lower customer spend on non-leading-edge equipment. Systems revenue was $3,730.6M and customer support-related revenue $2,110.9M. Gross margin improved 20 bps sequentially on better factory efficiencies. Operating expenses rose on beginning-of-calendar-year employee cost seasonality, higher headcount and **workforce optimization costs**, offset by lower elective deferred compensation costs and less outside services spend. For the nine months, gross margin improvement came from favorable customer mix, slightly offset by reduced factory efficiencies from **higher tariff-related spend**. CEO Tim Archer characterized the quarter as record revenue and EPS "as AI-driven demand reshapes the semiconductor industry." Management's outlook language in the 10-Q says wafer fabrication equipment investment was strong in calendar 2025 and that it believes there will be **continued growth in 2026, with the AI market driving higher industry spending across both memory and non-memory**. **Mix.** By market, Foundry fell to **54%** from 59% sequentially on lower mature-node investment, while Memory rose to **39%** from 34% on strengthening DRAM and non-volatile memory; Logic/IDM was 7%. Nine-month mix: Foundry 58%, Memory 36%, Logic/IDM 6% — a sharp shift from the prior-year nine months (42/43/15). By region for the quarter: **China 34%**, Korea 23%, Taiwan 23%, Japan 8%, U.S. 6%, Southeast Asia 4%, Europe 2%. Nine-month China share was 37% versus 33% a year earlier. **Deferred revenue and Japan shipments.** Deferred revenue was **$2.22 billion**, down slightly from $2.25 billion, with roughly **$300 million of decline in customer down payments** largely offset by increases in other components tied to growing business levels. Of the $2.22 billion, $1,508.9M is expected to be recognized in under a year. Separately, deferred revenue excludes shipments to Japanese customers, where control transfers on acceptance; estimated future revenue from those shipments was approximately **$434 million** at March 29, 2026, up from $226 million at December 28, 2025. **Taxes.** Tax expense of $186.1M, an effective rate of **9.3%**, down from 13.2% in the December quarter on higher stock-based compensation excess tax benefits and recognition of previously unrecognized tax benefits. Nine-month rate 12.6%, essentially flat year over year. BEPS 2.0 global minimum tax is fully effective this fiscal year; management expects to meet transitional safe harbor requirements in most jurisdictions, with limited jurisdictions subject to the tax. **Balance sheet at March 29, 2026.** Cash and equivalents $4,750.9M (from $6,390.7M at fiscal year-end); accounts receivable $4,132.9M (from $3,378.1M); inventories $4,000.0M (from $4,308.0M); property and equipment, net $2,853.6M; goodwill and intangibles, net $1,882.0M; total assets $20,791.9M. Deferred profit $2,091.3M; current portion of long-term debt $4.1M (from $754.3M); long-term debt and finance leases $3,730.4M; total liabilities $10,207.1M; stockholders' equity $10,584.8M. Warranty reserves ended at $255.0M. Guarantees and standby letters of credit outstanding: **$241.6 million**. **Cash flow and capital returns (nine months).** Operating cash flow **$4.40 billion**; investing used $778.4M, essentially all capital expenditures for manufacturing capacity and lab infrastructure; financing used $5.24 billion — **$3.60 billion of repurchases** including net share settlement and excise tax, **$945.3 million of dividends**, and **$754.1 million of debt principal and issuance costs**. In the March quarter alone: $1.16 billion of repurchases, $751.2 million of debt principal, $331.6 million of capex, $325.8 million of dividends, against $1.14 billion of operating cash generation. Cash fell to $4.77 billion from $6.20 billion sequentially. Dividends declared were **$0.26 per share** in the quarter ($0.78 for nine months), up from $0.23 ($0.69) a year earlier. **Buybacks.** Under the May 2024 authorization of up to an additional $10.00 billion, **$4,288.7 million remained available** at March 29, 2026 (from $7,517.2 million at fiscal year-end). Quarterly activity: 9,686k shares for $990.0M at $105.67 average (Sept quarter), 9,387k for $1,442.1M at $153.62 (Dec quarter), 3,516k for $796.4M at **$210.57** (March quarter) — the average price paid nearly doubled across three quarters. On **March 11, 2026** Lam entered a **$200.0 million accelerated share repurchase** agreement, taking initial delivery of approximately 685 thousand shares (75% of the prepayment divided by the March 11 closing price); the final share count depends on the VWAP over the repurchase period. The April 2025 ASRs ($500.0 million) settled finally in September 2025 with approximately 317 thousand additional shares, a weighted-average $91.00 per share for the transaction period. **Debt.** The **$750.0 million 2026 Notes settled at maturity** during the March quarter, which is why interest expense fell sequentially. On **March 10, 2026** the commercial paper program size was increased from $1.50 billion to **$2.00 billion**; there were **no outstanding CP borrowings** at March 29, 2026. The program is backstopped by the revolving credit facility. **Legal.** Lam states it is not currently party to any legal proceedings it believes material and has recorded no material litigation accrual. **Governance and management changes during the quarter.** On **February 3, 2026** the board appointed **Anirudh Devgan, Ph.D.** — CEO of Cadence Design Systems — as a director, expanding the board by one; he joined the Innovation and Technology Committee. The same day, Lam announced that **Patrick J. Lord, Ph.D. is retiring as chief operating officer effective March 6, 2026** after more than two decades with the company (including at Novellus), having given notice on January 30, 2026, and that **Seshasayee (Sesha) Varadarajan**, previously senior vice president of the Global Products Group, was appointed **executive vice president and chief operating officer effective March 6, 2026** (Form 8-K, accession 0000707549-26-000012, as amended by accession 0000707549-26-000014). Earlier, at the November 4, 2025 annual meeting, stockholders approved the **Lam 2025 Stock Incentive Plan** (Form 8-K, accession 0000707549-25-000094). Employee headcount was approximately **20,600** at March 29, 2026, up from roughly 19,000 in August 2025. --- ## Subsequent events Neither the Q3 FY2026 10-Q (accession 0000707549-26-000022) nor the FY2025 10-K (accession 0000707549-25-000075) contains a subsequent-events note. **No post-period acquisitions, divestitures, financings, borrowings or litigation outcomes are disclosed in either filing.** The 10-Q's notes end with segment reporting; the 10-K's end with restructuring charges. Post-period items that are on file elsewhere: - **Fourth-quarter fiscal 2026 guidance**, issued April 22, 2026 (Form 8-K, accession 0000707549-26-000020), for the quarter ending June 28, 2026: - Revenue **$6.60 billion ± $400 million** - Gross margin **50.5% ± 1%** - Operating margin **36.5% ± 1%** - Diluted EPS **$1.65 ± $0.15** - Diluted share count **1.255 billion** - GAAP-to-non-GAAP reconciling items are small — $2.7 million on gross margin, $3.0 million on operating margin, $3.3 million on EPS — all essentially acquisition-intangible amortization and note discount amortization. Guidance explicitly excludes any effect of business combinations, asset acquisitions, divestitures, restructuring, balance sheet valuation adjustments or financing arrangements completed after the release date. - **Settlement of the March 2026 accelerated share repurchase.** The $200.0 million ASR entered on March 11, 2026 had delivered only its initial ~685 thousand shares as of quarter end; the final share count is determined by the volume-weighted average price over a repurchase period extending past March 29, 2026.
