ASML says AI demand is outgrowing its 2027 and 2028 production plans

ASML says its planned production capacity for both 2027 and 2028 will fall short of customers’ equipment demand, as their expectations for AI investment keep rising. Reporting third-quarter results on 14 October, the company said it was examining a bigger expansion for 2028.[1]

Its lithography machines project miniature circuit patterns onto silicon wafers, one step in building a chip layer by layer. Their availability and speed help determine how much chipmaking work a factory can perform.[6]

The existing plan envisaged 30% more capacity in 2027 than in 2026, with another 30% increase in 2028 under investigation. Those figures concern low-NA extreme ultraviolet lithography and deep ultraviolet immersion systems. The new question is how far above the contemplated 2028 increase ASML can go. These are manufacturing plans and demand forecasts, with the additional expansion still being studied.[1]

The time horizon is striking. In its prepared remarks, ASML said orders were increasingly arriving for 2028, while some customers were expressing interest in ordering for 2029 and 2030. That later interest has not been presented as completed orders. Chief executive Christophe Fouquet linked customers’ confidence to longer commitments from their own buyers, particularly in advanced logic and memory.[3]

Demand is therefore travelling backwards through the supply chain. Expectations about future computing needs shape chipmakers’ factory plans; those plans become requests for the equipment that can make the chips. ASML’s announcement locates the constraint several investment decisions before a finished accelerator reaches a data centre.

The expansion already under way

ASML’s third-quarter net sales were €11.662 billion, up from €9.327 billion in the preceding quarter. Within that total, service and field-option sales reached €3.289 billion, compared with €2.762 billion in the second quarter. Gross margin rose from 54.0% to 57.5%. These are companywide results, covering more than equipment used for AI chips.[2]

The company expects roughly 65 low-NA EUV systems of output in 2026, compared with 44 shipped in 2025. Management’s immediate problem is thus how to extend an existing ramp. It also plans to introduce the NXE:3800F in small quantities at the beginning of 2027, specified at 260 wafers an hour against the NXE:3800E’s 230.[3]

That specification is about 13% higher, calculated as 260 divided by 230, minus one. It describes throughput at the lithography tool; it is not a forecast of 13% more finished AI chips. The early shipment plan also means the new model’s contribution will grow as more machines enter use.[3]

More capacity inside the same factory

A faster machine is a physical engineering project. ASML’s description of the existing NXE:3800E credits a redesigned bottom module, a new wafer handler, faster wafer stages and a more powerful light source for its increased throughput. Moving wafers, positioning them precisely and exposing them efficiently all contribute to how much work a system can perform.[5]

Upgrades offer another route. In the results interview, chief financial officer Roger Dassen described their appeal: customers can gain output within the space they already occupy. He said upgrades were the main reason installed-base revenue exceeded guidance by about €400 million. ASML is developing further upgrades alongside its new machines.[4]

This explains why counting future machine deliveries gives an incomplete picture of capacity. Output can also rise when each machine processes more wafers, or when equipment already installed becomes more productive. For a chipmaker waiting for additional tools, an improvement inside the existing factory can arrive on a different timetable from a new manufacturing line.

There is a commercial consequence as well. Dassen said ASML had completed discussions with key customers about pricing based on the value its products deliver. He expects the effect to start appearing partly during 2027, with the full effect in 2028 and beyond. That future pricing effect is separate from the upgrade business already helping current margins.[4]

For 2026, ASML now forecasts €44 billion–€45 billion in sales. The larger unanswered question concerns the production system being assembled for the years after it: how many additional machines can be built, and how much more work each can do. Both determine how much of today’s AI investment plans can become chipmaking capacity.[1]
