| 护城河评级 | 宽 The FY2026 10-K competition section describes tool-level qualification lock-in as the structural fact of the industry: 'semiconductor manufacturers must make a substantial investment to qualify and integrate new capital equipment into semiconductor production lines. As a result, once a semiconductor manufacturer has selected a particular supplier's equipment and qualified it for production, the manufacturer generally maintains that selection for that specific production application and technology node as long as the supplier's products demonstrate performance to specification in the installed base.' The filing then sizes what that incumbency is worth: of 23,232,690 thousand dollars of FY2026 revenue, 8,347,202 thousand - about 36% - was customer-support-related revenue and other, which the same document defines as 'sales of customer services, spares, upgrades, and non-leading-edge equipment' sold back into the installed base. A qualified position plus a third of revenue annuitised against it is a durable barrier rather than a cyclical one. | 窄 The FY2025 20-F positions Nebius as 'one of the few global, at scale, multi-tenant clouds purpose built for AI,' but the same filing names its central dependency plainly: 'We currently rely on Nvidia for the GPU chips we use' — a purpose-built neocloud renting a supply the hyperscalers it competes with also control, which is a real but narrow position. | 宽 In its 2025 Universal Registration Document the Group states a #1 market position in electrical distribution in each of its four end markets, plus #1 in grid and #1 in industrial data and safety, reached through a channel it sizes at more than 1.4 million contractors and electricians alongside panel builders, integrators and distributors; FY2025 closed with a record-high backlog of EUR 25,362 million and, per the CFO section, a fifth consecutive year of profitability expansion, with adjusted EBITA margin at 18.7% (+50bps organic). |
| 护城河类型 | 转换成本 The 10-K grounds the advantage in the cost of requalification, not in scale or patents: a customer that has qualified a competitor's tool is hard to win, and conversely Lam's own qualified positions persist for that application and node. The same section adds that the company must keep serving 'our installed base of customers through the delivery of high-quality and cost-efficient spare parts', naming the installed base as the asset being defended. | 成本规模 The moat the filing describes is engineering: designs that 'optimize power and cooling efficiency, lower latency' plus 'a consistent track record of being one of the first-to-deploy the latest generation of NVIDIA GPU chips' — density and time-to-deploy at scale, not a switching lock. | 转换成本 The URD's own durability table assigns a Reference Service Life of 20 years to low-voltage equipment and 15 years to medium-voltage products, and the Group monetizes that installed stock repeatedly: it attributes Field Services growth to an increasing installed base, notably from Data Center, and reports recurring revenue at 79% of its agnostic-software revenues (AVEVA, ETAP, RIB), up 2 points year on year, with AVEVA ARR up +12% as of December 31, 2025. |
| 领先地位 | 并列领先者 The 10-K claims position but not primacy: 'We believe we are in a strong position with our leadership and expertise in deposition, etch, and clean markets.' The same document names Applied Materials as primary competitor in deposition and Applied Materials, Hitachi and Tokyo Electron as primary competitors in etch, which is a shared-leadership structure rather than a clear single leader. | 快速追随者 The 20-F's own claim is 'one of the FEW global, at scale' AI clouds — a differentiated challenger to the hyperscalers it names as the competitive field, not a claimed leader of it; the first-to-deploy record is a follower's speed advantage, not category leadership. | 明确领先者 The URD's end-market pages report #1 positions in electrical distribution across all four end markets, #1 in grid, #1 in industrial data and safety, and the most complete data-center portfolio including liquid cooling. These are the Group's own stated positions rather than a third-party ranking, and the same document names ABB, Legrand, Siemens, Eaton, Emerson, Honeywell, Johnson Controls, Rockwell Automation, Fuji Electric, Mitsubishi Electric and Yokogawa as the peer panel it is benchmarked against for TSR, a panel its compensation policy characterizes as business competitors. |
| 定价权 | 中等 Real but bounded, and the filing is explicit that the recent gain was mix rather than price. Gross margin as a percent of total revenue rose 180 basis points to 50.5% in fiscal 2026 from 48.7% in fiscal 2025 (gross margin of 11,725,308 thousand dollars on revenue of 23,232,690 thousand, against 8,979,059 on 18,435,591; 7,052,791 on 14,905,386 in fiscal 2024), and the MD&A attributes that: 'Gross margin as a percentage of revenue increased in fiscal year 2026 compared to fiscal year 2025 largely due to favorable customer mix, partially offset by aluminum and steel tariff-related spend.' Against it, the same filing says manufacturers evaluate suppliers on 'overall cost of ownership', that the spares business competes with third-party spare parts providers, and that the customer list is a handful of very large buyers (Micron, Samsung, SK hynix and TSMC named as the most significant customers). | 弱 The filing frames a 'highly competitive' market with 'frequent introduction of new or improved solutions' and a GPU cost base set by a single supplier (NVIDIA) — a renter of compute competing on efficiency has little list-price control. | 中等 Price is real but has not been covering input costs. FY2025 gross margin fell to 42.1%, down 40bps organic, with the URD stating that accelerating Q4 product pricing was insufficient to fully offset mix and raw-material cost inflation inclusive of tariffs; in the July 30, 2026 half-year release, gross pricing on products of +EUR 280 million was outweighed by a raw-material impact of -EUR 330 million and net tariffs of -EUR 104 million for a net price impact of -EUR 154 million, and the Group says it expects to be net-price positive only in H2 2026. |
| 综述 | Lam sells etch, deposition and clean tools into a per-node, per-application qualification process that its own 10-K says customers generally do not revisit once a supplier is qualified. The result is two linked economics, and the FY2026 filing splits them: systems revenue of 14,885,488 thousand dollars and customer-support-related revenue and other of 8,347,202 thousand, on total revenue of 23,232,690 thousand. The second line is the installed-base annuity - services, spares, upgrades and refurbished Reliant tools sold wherever Lam already holds the process step. The 10-K names Applied Materials as the primary competitor in dielectric and metals deposition, ASM International and Wonik IPS in ALD/PECVD, and Applied Materials, Hitachi and Tokyo Electron in etch, so this is shared rather than sole leadership. The live erosion risk is policy, not a rival product: China was 34% of revenue in both fiscal 2026 and fiscal 2025 (7,859,811 thousand dollars in FY2026, the largest single region), and the filing states that U.S. export controls on sales to customers in China, including entity listings of multiple customers, restrict sales of equipment and spare parts by U.S. suppliers and thereby 'provides an advantage to our international competitors that are not subject to these restrictions'. | Nebius sells a 'unified full-stack AI cloud that spans the complete AI journey – from compute capacity to software and services,' with hardware and software built in-house — the neocloud pitch of hyperscaler reliability at purpose-built efficiency, and a first-to-deploy record on new NVIDIA silicon. Two things bound the moat, both from the filing: it 'currently rel[ies] on Nvidia for the GPU chips,' the same constraint every neocloud shares, and it is a Nasdaq 'Controlled Company' whose founding shareholder holds concentrated voting power. The three non-core segments (Toloka, Avride, TripleTen) are separate businesses, not the cloud moat. | Schneider sells electrification, automation and digitalization into four end markets — Data Center & Networks (30% of 2025 orders), Buildings (29%), Industry (27%) and Infrastructure (14%) — and its 2025 URD claims a #1 position in electrical distribution in every one of them, sold through an ecosystem of panel builders, integrators, distributors and more than 1.4 million contractors and electricians. Energy Management is the larger and higher-margin half: EUR 33,130 million of FY2025 revenue, 83% of the Group, up +10.3% organic at a 21.8% adjusted EBITA margin, against EUR 7,022 million and 14.2% at Industrial Automation. In the July 30, 2026 half-year release the Data Center end-market continues to lead growth: Systems, 35% of Q2 revenues, grew +28% organic with prefabricated solutions, cooling technologies and 3-phase UPS all seeing significant growth. |
| 产业链位置 | Upstream wafer-fabrication-equipment supplier; the 10-K names Micron, Samsung, SK hynix and TSMC as its most significant customers across FY2024-FY2026, so Lam sits one step above the memory and foundry capacity that AI compute depends on. | Layer-8 neocloud — a purpose-built AI compute provider reselling NVIDIA silicon at scale. | Supplies the power and cooling layer beneath AI compute: Data Center & Networks was 30% of 2025 orders, a market the URD places on a market CAGR above 10% from 2025 to 2030. |
