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.

The FY2025 10-K shows a moat that still pays but no longer compounds: total gross margin of 64.9% and remaining performance obligations of $43,533 million (up 6%) against a Networking product category that fell from $34,570 million in fiscal 2023 to $29,229 million in fiscal 2024 to $28,304 million in fiscal 2025, and a product gross-margin bridge in which 'Product pricing' subtracted 1.6 percentage points. All of the reported category growth came from Splunk-carrying lines - Security +59% and Observability +26%. Real and durable, but bounded: narrow, not wide.

The FY2026 10-K (filed 2026-07-29) restates both structural mechanisms verbatim. On cost: the cloud business 'benefits from three economies of scale' — datacenters with 'significantly lower cost per unit than smaller ones', demand aggregation, and multi-tenancy that lowers maintenance labor. On ecosystem: 'A well-established ecosystem creates beneficial network effects among users, application developers, and the platform provider that can accelerate growth.' Both are load-bearing at the new scale — 'Microsoft Cloud revenue increased 27% to $214.4 billion' and 'Commercial remaining performance obligation increased 84% to $678 billion.' Rated wide but held below full confidence because the same filing still cautions that 'Barriers to entry in many of our businesses are low.'

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.

The durable piece is the contracted annuity attached to installed equipment: total remaining performance obligations of $43,533 million, of which $21,961 million is services and $21,810 million is long-term (recognised beyond twelve months), carried at a services gross margin of 68.5% that has risen for three consecutive years from 66.4% and 68.1%. Customers keep paying for support on gear they already run.

The FY2026 10-K keeps the ecosystem passage scoped to the firm: 'An important element of our business model has been to create platform-based ecosystems on which many participants can build diverse solutions. A well-established ecosystem creates beneficial network effects among users, application developers, and the platform provider that can accelerate growth.' That remains the one moat mechanism the filing asserts about Microsoft as a whole; the cost-of-scale passage stays scoped to 'our cloud business'.

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.

The 10-K names no competitor and discloses no market share anywhere in Management's Discussion and Analysis. The positional facts it does give are scale and direction: Networking product revenue of $28,304 million in fiscal 2025 - by far the largest of its four categories - but down $6.3 billion from fiscal 2023, with channel partner financing volume falling from $32.1 billion to $27.1 billion to $24.9 billion across fiscal 2023-2025.

The FY2026 10-K asserts leadership nowhere. Its AI offerings 'compete with AI products from hyperscalers, as well as products from other emerging competitors and other open-source offerings, many of which are also current or potential partners' — one of a small set at hyperscale in cloud and AI, an incumbent in productivity and PC operating systems.

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).

The product gross-margin bridge attributes fiscal 2025's 0.2-point improvement to productivity (+2.0 points) and mix (+1.1 points) while 'Product pricing' subtracted 1.6 points; a legal dispute with a supplier cost a further 0.8 points. Total gross margin of 64.9% (product 63.7%, services 68.5%) is held by cost and mix, not by price.

The FY2026 10-K reports 'Gross margin increased $31.6 billion or 16% with growth across each of our segments', with 'Microsoft 365 Commercial revenue ... mainly affected by a combination of continued installed base growth and average revenue per user expansion'. The honest caveat: gross margin percentage 'decreased slightly driven by continued investments in AI infrastructure and growing AI product usage', with Microsoft Cloud gross margin down to 66%.

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.

Supplies networking into AI datacenters: the 10-K ties Americas service provider and cloud growth to 'AI infrastructure revenue from webscale customers' and to Cisco Silicon One manufacturing commitments.

Hyperscale AI-infrastructure buyer and platform distributor: monetizes upstream compute through Azure, Microsoft 365 Copilot, and the developer ecosystem.
