Moat
moat: latest change 2026-08-07 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'.
Rating: wide
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.
Type: switching costs
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.
Leadership: co leader
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.
Pricing power: moderate
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).
