| Moat rating | narrow Integrated Report 2026 (issued 2026-09-15) documents strong positions across the line: by Tokyo Electron's own estimate it ranks No. 1 in diffusion furnaces, batch deposition, metal deposition, coater/developers, gas chemical etch and wafer probers, No. 2 in plasma etch and bonders and No. 3 in cleaning, and holds a "100% share" of coater/developers for EUV lithography; its installed base, industry-leading by its own estimate, is approximately 100,000 units, growing by approximately 4,000-6,000 units a year; and its 26,592 patents rank No. 1 in the semiconductor production equipment industry on the LexisNexis PatentSight+ database. Reported returns stayed high through a sales decline: gross profit margin stayed between 44.6% and 47.1% and ROE between 21.8% and 37.2% across fiscal 2022-2026, including fiscal 2024 when net sales fell to ¥1,830.5 billion. The share ranks, the EUV share and the installed-base lead are company estimates, not third-party data. | wide The FY2025 10-K positions Synopsys as 'a global leader in supplying the mission-critical EDA solutions' and, after the Ansys merger, 'the global leader in engineering S&A software' — two adjacent franchises the filing says now sit in one portfolio. | wide The FY2025 10-K describes the nation's largest nuclear fleet — approximately 22 GW across 14 stations producing 68% of 2025 electric supply — running at a 94.7% capacity factor that 'has been approximately four percentage points better than the industry average annually since 2013', with NRC licences extending to 2054 and an IRA nuclear production tax credit floor from 2024. |
| Moat type | intangibles ip The report calls its patent portfolio its "fifth strength" and says that "by supporting our other four strengths, it serves a vital role as the foundation" for medium- to long-term corporate value: 26,592 patents as of March 31, 2026, 1,415 inventions created in Japan and 345 overseas in 2025, and Clarivate Top 100 Global Innovators recognition for the fifth consecutive year. The other strengths rest on the same proprietary process know-how — co-created technology roadmaps that evaluate technologies "for the next four generations and beyond" with customers, "numerous development PORs" (process of record) in the frontend business, and the EUV coater/developer position — so proprietary process technology, reinforced by qualification in customers' process flows, is the moat source. | switching costs The 10-K describes EDA as 'mission-critical' software licensed mostly as network licences across a customer's whole design flow, with post-contract support providing 'frequent updates to maintain the utilization of the software due to rapid changes in technology' — a dependence that renews at every process node. | cost scale The cited edge is operating cost at scale: average refuelling outages of 22 days in 2025 against industry averages of 33 and 38 days in 2024 and 2023, a capacity factor about four points above the industry every year since 2013, and 'significant economies of scale' in what the filing calls the largest US customer-facing energy platform. |
| Leadership | co leader The CEO's message describes Tokyo Electron as "one of the world's leading suppliers of semiconductor production equipment" and states a "goal of becoming number one globally" — it does not claim to be the largest supplier overall — while by its own estimate it ranks No. 1 in six charted segments (diffusion furnace, batch deposition, metal deposition, coater/developer, gas chemical etch, wafer prober), No. 2 in plasma etch and bonders, and No. 3 in cleaning. | co leader The 10-K claims global leadership in EDA while stating 'The EDA industry is highly competitive' and that Synopsys competes against other EDA vendors and against customers' own internally developed design tools. | clear leader The 10-K states Constellation is 'the largest nuclear energy company in the U.S.', is 'the nation's largest energy supplier for C&I and residential power volumes' based on EEI data, and has 'over 32% of the C&I market share of direct customer business'. |
| Pricing power | moderate Gross profit margin held in a 44.6%-47.1% range over fiscal 2022-2026, including fiscal 2024's sales decline, but in fiscal 2026 it fell 1.8 points to 45.3% "due to factors such as higher raw material prices and increased labor costs" even as net sales reached a record, and the CEO lists "revising prices appropriately with respect to cost increases caused by inflation" among five initiatives needed to improve the operating margin. | moderate The 10-K lists 'license terms, price and payment terms' among the principal competitive factors and states 'No single factor drives an EDA customer's buying decision'; licence fees depend on licence type, product mix and the number of copies licensed. | moderate The 10-K states 'While providing customers with a competitive price is a key focus' in retail, on roughly two-year average C&I contract terms with 77% power and 84% gas renewal rates in 2025, and the nuclear fleet's downside is set by the IRA nuclear PTC 'as unit revenues decline below levels established in the IRA'; SEC-reported operating income was 13.6% of revenue in 2025. |
| Summary | Tokyo Electron makes wafer fab equipment for what its Integrated Report 2026 calls the "four key processes necessary for semiconductor scaling: deposition, coater/developer, etch, and cleaning", plus wafer probers and bonders for test and advanced packaging. The report grounds its edge in breadth and incumbency: leading share estimates in most of its segments, an estimated 100% share of EUV coater/developers, an installed base of approximately 100,000 units, industry-leading by its own estimate, feeding a Field Solutions business that sold ¥626.0 billion of parts, services, used equipment and modifications in fiscal 2026, and the industry's largest patent portfolio. Fiscal 2026 net sales were a record ¥2,443,533 million, but gross profit margin fell 1.8 points to 45.3% on higher raw material prices and labor costs, and operating margin fell 3.1 points to 25.6% as R&D expenses rose 11.1% to ¥277,866 million. China accounted for 34.1% of fiscal 2026 net sales, down from 41.7% the year before. | Synopsys sells the sign-off tools (PrimeTime static timing, IC Validator physical verification) and the silicon-proven IP that chip designs are built against, and the FY2025 Ansys merger added the multiphysics sign-off products (RedHawk-SC, Totem-SC) to the same portfolio, growing headcount about 40% to roughly 28,000. | Constellation pairs the largest US nuclear fleet with the largest competitive retail book, which lets it sell around-the-clock carbon-free power under long-term contracts such as the 20-year Microsoft PPA restarting Three Mile Island Unit 1 as the 835 MW Crane Clean Energy Center. |
| Chain position | Upstream equipment supplier to chipmakers: fiscal 2026 new-equipment sales of ¥1,775.4 billion went 59% to non-memory (logic, foundry, others), 31% to DRAM and 10% to NAND; by region, China took 34.1%, South Korea 22.3% and Taiwan 20.4% of net sales. | Design-and-IP layer feeding both the chip designers and, post-Ansys, the systems companies that simulate the products those chips go into. | Generator and retailer in one — the fleet is the physical supply behind the long-term carbon-free contracts it sells to large corporate buyers. |
