ASML: a difficult-to-substitute production technology inside the semiconductor chain

ASML's structural relevance comes from advanced lithography capabilities that can be difficult to replace within semiconductor investment horizons. The company supplies technology; the Dutch state separately controls covered export licences.
Context
Advanced semiconductor production depends on specialized equipment, supplier ecosystems and regulatory access whose substitution can take years.
Key risk
Treating ASML's technical position as control of the entire semiconductor chain or as sovereign export authority overstates its rights.

ASML is structurally relevant for a reason different from financial scale or commodity ownership: it supplies lithography systems used at critical stages of semiconductor manufacturing, including extreme-ultraviolet (EUV) systems for advanced chips. The decisive variable is substitutability. If chipmakers cannot reproduce or replace a production capability within the relevant investment horizon, access to the supplier becomes a constraint on downstream manufacturing capacity.

The structural claim must remain specific. ASML does not control the entire semiconductor stack, does not issue export licences and does not decide where every advanced chip is manufactured. Its capability sits inside a wider chain that includes optics, light sources, chemicals, masks, deposition and etch equipment, fabs, design tools, packaging, electricity, capital and sovereign trade rules.

System shipments show industrial scale, not the magnitude of the chokepoint

ASML reported €32.7 billion of net sales in 2025, with €4.7 billion of R&D. It recognized revenue on 48 EUV systems and 279 DUV systems during the year. In the first half of 2026, it sold 67 new lithography systems in Q1 and 86 in Q2. ASML — 2025 Annual Report ASML — Q2 2026 results

Shipment count is not a direct measure of strategic importance. EUV and DUV systems have different capabilities and prices, while installed machines continue to produce after the original sale. The structural question is which manufacturing steps require technology that cannot be substituted at acceptable yield, cost and time.

The mechanism is a production dependency, not financial ownership

Lithography transfers patterns onto wafers repeatedly through the semiconductor process. For advanced manufacturing, the relevant dependency is not simply purchasing a machine; fabs must integrate the system with process recipes, masks, materials, metrology and other equipment to achieve usable yield.

Transmission chain
  1. ASML R&D and supplier network
  2. lithography system
  3. semiconductor fab process integration
  4. patterned wafers
  5. advanced chips
  6. computing, industrial and security applications
  1. ASML service and upgrades
  2. installed system availability and productivity
  3. fab throughput and process economics

A delay in system delivery can therefore affect the timing of fab capacity additions. But it is only one potential binding constraint: power, clean-room construction, other semiconductor equipment, skilled labor and customer demand can all become binding instead.

Low substitutability depends on engineering time, not on brand status

The strongest structural claim concerns advanced EUV capability. Replacing a complex lithography platform requires more than a competing corporate balance sheet. It requires years of accumulated optical engineering, precision mechatronics, source technology, software, process integration, supplier qualification and customer learning.

That is why the appropriate horizon matters. A capability can be difficult to substitute over one to five years without being permanently irreplaceable. Customers can also redesign process flows, extend DUV multi-patterning in some applications, adjust node choices or delay capacity. Those responses may be costly, but they are alternatives and should be part of the dependency assessment.

Export authority belongs to the Dutch state, not to ASML

The Netherlands subjects specified advanced semiconductor-manufacturing equipment to national export authorisation requirements. Its 2025 revision explicitly noted that lithography equipment was already among the technologies covered and that licences are decided by the government case by case. The measure applies to exports from the Netherlands to destinations outside the EU and is not a blanket export ban. Government of the Netherlands — semiconductor equipment export controls

That creates two distinct capabilities in the same chain:

Transmission chain
  1. ASML
  2. technical capability to manufacture and service specified lithography systems
  3. potential supply to customers
  1. Dutch state
  2. legal authority over covered exports
  3. licence granted, conditioned or refused
  4. geographic access to specified equipment

Conflating them would overstate ASML's sovereign authority and understate the state's regulatory role. Export controls can also alter ASML's commercial opportunities without changing the underlying technical capability of its systems.

The installed base creates a longer-lived relationship than a one-time equipment sale

ASML reported €8.2 billion in installed-base-management sales in 2025. In Q2 2026, installed-base-management sales were €2.762 billion. ASML — 2025 Annual Report ASML — Q2 2026 results

This service relationship matters because semiconductor tools operate for many years and their productivity can change through maintenance and upgrades. The installed base therefore creates recurring technical dependence after the initial capital purchase. It is still bounded by contracts, customer engineering capacity, spare-parts inventories and the possibility of eventually replacing systems.

Assessment

ASML is a strategic actor because it supplies a difficult-to-substitute production capability at a consequential point in semiconductor manufacturing. Its structural relevance is strongest where a fab's feasible process technology depends on ASML equipment over a horizon in which alternative systems cannot be qualified and scaled.

The correct boundary is equally important. ASML does not control chip design, fabs, the full equipment stack or export policy. The dependency emerges from a chain of technical requirements, customer integration and regulatory access. Monitoring should therefore focus on EUV and High-NA adoption, system productivity, customer qualification, supplier capacity, installed-base service, competing process routes and changes in export-control scope.
