| 護城河評級 | 正在侵蝕 The FY2025 10-K (filed 2026-01-23) repeats the concession, now broadened: 'we have lost market share in recent years, including in both client and data center markets, in the market for x86-based semiconductor products, and more generally in the markets for semiconductor compute products, as competitors have introduced highly competitive data center and client platform products.' It adds that the data-center business 'has been further negatively impacted in the past few years by the significant shift of customer spend toward GPUs optimized for AI workloads' — a historically wide moat still actively eroding. | 寬 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. | 寬 TSMC's 2025 Form 20-F reports a 59.9% gross margin (up from 56.1% in 2024) and describes the company as "the technology leader among the dedicated foundries" in advanced (7-nanometer-and-below) node revenue — a durable, hard-to-replicate process-and-scale advantage that rivals with "greater financial and other resources" have not matched. |
| 護城河類型 | 無形資產與智慧財產 The durable assets remain the x86 architecture and process-technology IP: the FY2025 10-K claims 'We are a global leader in the design and manufacturing of CPUs and other semiconductor products' and stakes the recovery on process IP — 'Intel 18A introduces two industry firsts in high-volume semiconductor manufacturing: gate-all-around transistors (RibbonFET) and backside power delivery (PowerVia).' | 轉換成本 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. | 無形資產與智慧財產 Per its 2025 Form 20-F, TSMC "compete[s] primarily on process technologies, manufacturing excellence, customer trust and service quality" and has "been issued a substantial number of patents," with 2-nanometer in volume production in 2025 and 16-angstrom risk production targeted for 2026 — proprietary process-technology know-how and IP, not merely capital (the filing explicitly notes some competitors may have greater financial resources yet still trail), are the core barrier. |
| 領先地位 | 快速追隨者 The FY2025 10-K still opens 'We are a global leader in the design and manufacturing of CPUs', yet concedes lost share 'in both client and data center markets' and a spend shift 'toward GPUs optimized for AI workloads' where Intel participates via 'Xeon, AI PCs, Arc GPUs and our open software stack' plus 'inference-optimized GPUs on a targeted annual cadence' — following the AI compute market rather than setting its pace. | 並列領先者 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. | 明確領先者 Self-described in its 2025 20-F as "the technology leader among the dedicated foundries" in net revenue of advanced semiconductors at 7-nanometer and below; reached 2nm volume production in 2025, and Epoch AI estimates ~90% share of global advanced-node fabrication. |
| 定價權 | 弱 The FY2025 10-K states the mechanism itself: higher-priced products 'have lower margins as they are produced at external foundries rather than in our manufacturing facilities. To the extent demand shifts from our higher-margin to lower-margin products in any of our market segments, our gross margin percentage has decreased and may decrease again' — plus $878 million of 2025 inventory reserves on the early Intel 18A ramp. | 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). | 強 2025 gross margin of 59.9% (up from 56.1% in 2024), attributed in the 20-F to higher capacity utilization and cost improvement, reflects strong pricing power at the leading edge despite the heavy capital intensity of new-node ramps. |
| 綜述 | Still the incumbent x86 CPU designer-manufacturer — FY2025 revenue was $52.9 billion, roughly flat — but the filing concedes lost share in client and data center and an AI-driven customer shift toward GPUs; the counter-thesis is process IP, with Intel 18A shipping in Core Ultra Series 3 ('the first products to be manufactured using our new Intel 18A process technology') and Intel 14A 'designed from inception as an offering to external customers.' | 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'. | TSMC is the world's largest dedicated semiconductor foundry and, per its 2025 Form 20-F, the self-described technology leader among dedicated foundries in advanced (7nm-and-below) node revenue, having reached 2-nanometer volume production in 2025 with 16-angstrom risk production on track for 2026. Independent research (Epoch AI) estimates it controls roughly 90% of global advanced-node fabrication; sustained by US$7.9 billion of 2025 R&D, a large patent portfolio and 59.9% gross margins, this process-technology and scale advantage has proven durable even against rivals with greater financial resources. |
| 產業鏈位置 | x86 compute incumbent and would-be US leading-edge foundry; its 18A/14A ramp is the main Western alternative to TSMC at the leading edge. | 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. | The critical leading-edge fabrication and advanced-packaging (CoWoS) layer of the AI supply chain — high-performance computing was 58% of TSMC's 2025 revenue, and it supplies leading-edge N2/N3/N4 logic to the fabless IC-design and system companies that design AI accelerators. |
