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 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.

The moat is narrow rather than wide. The filing names real entry barriers in launch — capital, technological expertise, licences and established government and commercial relationships — and adds spectrum and orbital resources in connectivity, while warning that the company's "leadership position in various markets, especially in orbital launch services" could attract competition-law scrutiny. The AI segment has barriers too: "Our AI businesses likewise compete in markets characterized by significant barriers to entry." Durability is capped by three-to-five-year satellite lives that force perpetual replacement launches, but the moat is not eroding: subscribers are 12.0M against 6.0M.

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 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.

The advantage is cost and scale. The stated model is extreme vertical integration plus reusability driving unit cost down: per NASA, the first Falcon 9 cut launch cost to about $2,700/kg, roughly 85% below the $18,500/kg historical average, and Falcon 9 has "demonstrated the ability to refly a first-stage 34 times" (3/31/26). The filing credits rising cadence, cargo capacity and "declining unit costs—driven by rapid reusability—have generated a compounding competitive advantage". SpaceX also launches its own constellation, and Competition notes "some of these service providers are also launch customers of SpaceX". Spectrum and licence intangibles reinforce the cost advantage.

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 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.

SpaceX leads clearly in its two established segments but not in its newest. The prospectus calls it "the primary launch provider for the U.S. government" — 11 of 12 NSSL medium and heavy lift missions and all five U.S. crew and cargo ISS missions for NASA in 2025 — and says Starlink is "the sole low-latency network available globally", low-latency self-defined as under 70ms; it flags competition-law scrutiny risk from that leadership. AI is the exception, with OpenAI, Anthropic, Google, Meta and Microsoft named as competitors, some with greater resources, in a segment the filing calls early stage. Cadence slipped: H1 2026 Falcon launches 77 versus 81, mass to orbit 1,041t versus 1,102t.

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 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.

Pricing power is moderate — a deliberate give-back from a cost position rather than weakness. Management states its strategy is "rather than prioritizing increases in ARPU" and expects Starlink ARPU to keep declining as it adds lower-priced plans and adjusts monthly service fees; the Q2 10-Q shows ARPU of $66 versus $85 while Connectivity operating income rose 79.4%. Launch sells on fixed-price contracts, one to five years for Launch Services and up to fourteen for Launch and Development. Concentration is material: about one-fifth of 2025 revenue came from U.S. federal agencies, with all launch contracts firm fixed-price and terminable at the government's convenience without advance notice.

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.
