ASML's Growth Story Now Runs Through a Lens Factory in Oberkochen
Published on 10/29/2026 at 20:42 | Editorial boerse-global.de
ASML's biggest constraint on future revenue may not sit in Veldhoven at all. It sits in Oberkochen, where Zeiss builds the precision optics that go into every EUV machine — and where production and metrology capacity, according to ITmedia, is now the binding limit on how fast ASML can expand output.
That supply-side bottleneck is the lens through which investors are increasingly reading the Dutch group's story. Demand is not the problem. ASML Korea said at a Tech Summit today that the shortfall in AI semiconductor supply could persist for at least five years, with demand for AI chips growing more than three times as fast as for general-purpose semiconductors. In an extended scenario, the undersupply could run into the early 2030s. That is a company forecast, not a settled outcome — and it does nothing on its own to prove ASML can convert fresh orders into shipped systems and profitable revenue.
A 30% Step-Up, and a Second Year Not Yet Decided
The plan described by ITmedia calls for production capacity for Low-NA EUV systems to rise 30% in 2027, with a comparable expansion pencilled in for DUV immersion tools. A further increase of similar magnitude is under consideration for both product groups the following year — but that second leg has not been signed off.
Zeiss is adding roughly 25,000 square metres of production-related facilities in Oberkochen. How much that translates into additional high-end EUV optics has not been disclosed. For shareholders, the usable optic supply matters more than the square footage: the running of precision optics equipment, the number of available optic modules and deliveries of finished systems are the metrics ASML itself tracks, and they are what tie capacity expansion to the bottom line.
Should investors sell immediately? Or is it worth buying ASML Holding?
The Numbers Behind the Debate
The operating base is already substantial. ASML reported third-quarter 2026 net sales of EUR 11.7 billion, a net profit of EUR 5.0 billion and a gross margin of 57.5%. Media reports suggest negotiated price increases on key EUV systems will begin feeding through to results from 2027 and take full effect in 2028. Should extra capacity and those pricing effects arrive together, the earnings base could strengthen further — though the timing remains a precondition rather than a promise.
The company has also said its planned supply will not fully cover customer demand, a remark that referred to intended capacity for 2027–2028. It points to a high utilisation outlook without guaranteeing open-ended growth.
Why the Dutch Economy Is Watching
ASML's reach extends well past its own accounts. An ING estimate published on Monday put the company's direct contribution to the Dutch economy at 1.6% in 2026, up from an estimated 1.3% in 2025. Including suppliers and investment, the wider economic share tied to ASML could climb to 2.2% — a broader measure that should not be confused with the company's direct contribution. For investors, the figure is context rather than an earnings pledge: it describes the scale of the business, not the durability of its growth.
Two Risks That Don't Start With a Demand Collapse
The bear case does not require orders to dry up. Delayed optics deliveries alone could stop ASML from serving existing demand at the pace it has planned, leaving customer interest as a positive signal rather than a reliable short-term growth gauge.
China adds a second layer. System sales to the country accounted for 23% of the total in the third quarter of 2026, and media reports say CXMT and YMTC have secured DUV lithography tools covering three years of growth. Such stockpiling makes subsequent demand harder to read and should not be extrapolated as a lasting order rate. Reports also indicate Washington is pressing The Hague for a full export ban on those tools to China — a step that has not been described as decided, but one that could narrow sales opportunities, especially if EUV capacity expansion were to slow at the same time.
ASML Holding at a turning point? This analysis reveals what investors need to know now.
What to Watch
Sentiment is clearly sensitive to the long view. On 15 October, Reuters reported investor doubts over the durability of AI infrastructure spending and the lofty expectations for 2028–2029, compounded by worries about financing costs and data-centre power supply.
The next hard test is the capacity increase scheduled for 2027, when the reported EUV price rises should also begin to show through. Both are forward-looking and must still appear in the accounts. The yardstick for investors is therefore not further declarations of demand but progress in optic modules, finished systems and profitable deliveries — and only their combined momentum would show that ASML can turn the demand it has announced into economic gain.
