ASML’s Capacity Shortfall Is Increasing the Value of Machines Already in Service

ASML reported €11.7 billion of quarterly revenue on October 14, alongside a warning that its currently planned supply for 2027 and 2028 would fall short of customer demand. For the Dutch semiconductor-equipment manufacturer, that combination creates two opportunities: delivering more machines and helping customers produce more chips with the equipment they already own.

The third-quarter announcement shows both contributing. Revenue from servicing and upgrading installed equipment reached €3.3 billion, helping lift gross margin to 57.5%. Management is now examining additional manufacturing capacity beyond its previously discussed expansion plans.

How ASML earns money from a chip factory

ASML supplies the lithography equipment that chipmakers use to print circuit patterns onto silicon wafers. Its technology combines precision optics, mechanics and software to reproduce those patterns repeatedly across a wafer and through successive manufacturing layers. Different layers require different levels of precision, so a factory uses several types of lithography equipment.

Extreme ultraviolet, or EUV, systems handle particularly small features; deep ultraviolet, or DUV, systems serve other layers and manufacturing requirements. ASML also sells services and upgrades for machines operating at customer sites. This gives the business an ongoing relationship with equipment after its initial installation.

For a chipmaker, the economics depend partly on how many usable wafers a machine can process within a given period. An upgrade that raises throughput can increase output within an existing factory footprint. Our interpretation is that this becomes especially attractive when new equipment takes time to obtain: customers can pursue additional production while their larger expansion projects progress.

Upgrades are contributing to the margin improvement

In the results interview, management said installed-base revenue exceeded its quarterly forecast by approximately €400 million, primarily because of upgrade demand. It also identified that business as a principal contributor to the gross-margin outperformance.

The product roadmap illustrates the mechanism. ASML expects its NXE:3800F system, initially available in small quantities in 2027, to increase throughput from 230 to 260 wafers per hour. That represents approximately 13% more nominal throughput. Actual factory benefits will also depend on utilization, process requirements and constraints elsewhere in production.

This offers a useful way to assess the business. Equipment shipments measure one source of growth, while productivity improvements create another route to customer value. The commercial opportunity depends on the value of additional wafer output relative to the cost and implementation requirements of an upgrade.

Pricing provides a further potential contribution. Management said discussions on value-based pricing had concluded with key customers, with effects beginning partly in 2027 and becoming fully visible from 2028. Consequently, the timing of pricing benefits extends beyond the current quarter’s improvement.

Expanding supply requires more than additional factory space

ASML’s July capacity plan started from approximately 65 conventional EUV systems and 130 DUV immersion systems of annual capacity in 2026. It envisaged a 30% increase in 2027 and was investigating another 30% increase in 2028. Two successive increases of that size would compound to approximately 69% above the starting capacity.

These plans concern specific equipment categories. They provide a framework for manufacturing expansion, with actual shipments dependent on execution and customer requirements. October’s warning indicates that customer demand forecasts have continued to rise against that framework.

The timing of ASML’s new Eindhoven campus helps explain why the response takes time. Construction began in September, with the first phase expected to finish in 2029. That phase will accommodate at least 3,000 employees, primarily teams relocating from existing locations.

A planned flow-factory model is intended to improve how modules, materials and installation work move through production. Our assessment is that manufacturing processes and supplier readiness deserve as much attention as the physical building: additional floor space becomes useful capacity only when the necessary components, people and production sequences are available. The 2029 completion date also places this investment beyond the immediate 2027–2028 supply challenge.

Reported profit includes an investment gain

ASML’s US GAAP financial statements reconcile third-quarter earnings as follows:

Management attributed approximately €500 million to revaluing its initial Mistral AI investment. Operating income therefore provides a cleaner starting point for examining equipment-business performance.

Operating cash flow was €11,797.6 million, including a €7,009.0 million contribution from changes in assets and liabilities. Deducting €413.3 million of property and equipment purchases and €33.9 million of intangible purchases gives calculated free cash flow of €11,350.4 million.

After all investing and financing flows and currency effects, cash increased €1,359.0 million to €8,030.9 million. Short-term investments added €4,704.2 million, taking combined liquidity to €12,735.1 million. The working-capital contribution makes quarterly cash conversion sensitive to payment timing.

A larger fourth quarter creates the next execution test

ASML expects fourth-quarter revenue of €14.2 billion–€15.2 billion, with gross margin around 57%. Full-year revenue guidance is now €44 billion–€45 billion, compared with July’s €43 billion–€45 billion range. The change raises the lower bound while retaining the previous upper bound.

For the investment case, the next evidence will come from three connected outcomes: delivery of the larger quarterly revenue target, sustained customer spending on upgrades, and a more concrete plan for additional manufacturing output. These will help establish how much of today’s demand visibility can become profitable sales within the next two years.

Longer-term customer forecasts still involve uncertainty. ASML identifies order delays, cancellations, export restrictions and component availability among its risks. Capacity investment therefore requires decisions before all future revenue is secured.

The issue to follow is whether additional machines, higher throughput and pricing can advance together. A delay in any one of those areas would change the timing of earnings growth even if customers’ underlying appetite for more wafer capacity remains intact.
