ASML's record quarter and a supply gap that now stretches to 2028

ASML reported total net sales of €11.662 billion (~US$13.1 billion) for the third quarter ended 27 September 2026, up from €9.326 billion (~US$10.5 billion) in the second quarter, according to its results release of 14 October 2026 (US GAAP). Gross profit was €6.700 billion (~US$7.51 billion) and the gross margin 57.5%, up from 54.0%. Net income was €4.960 billion (~US$5.56 billion) and basic earnings per share €12.95 (~US$14.5). Installed base management sales, ASML's service and upgrade business, were €3.289 billion (~US$3.69 billion).

ASML sold 113 new lithography systems in the quarter (86 in Q2) and 8 used systems. Cash and short-term investments ended the quarter at €12.735 billion (~US$14.3 billion).

Demand ahead of supply

In its release, ASML says customers keep raising short- and medium-term equipment forecasts, and some are interested in placing orders for 2029 and even 2030. The company now expects its supply as currently planned for both 2027 and 2028 will not fully meet customer demand, and is studying ways to add capacity for 2028 beyond the 30% increase it previously described.

For the fourth quarter ASML guides for net sales of €14.2–15.2 billion (~US$15.9–17 billion) and a gross margin around 57%. For 2026 it expects net sales of €44–45 billion (~US$49.3–50.4 billion) and a gross margin around 56%. On its investor call, ASML said it expects EUV sales to grow more than 45% in 2026 and China to account for around 20% of total net sales this year.

ASML also guides fourth-quarter R&D costs of around €1.2 billion (~US$1.34 billion) and SG&A of around €0.4 billion (~US$448 million). The figures are internally consistent: nine-month sales of €29,755.4 million (~US$33.3 billion) plus the Q4 range give €43.96–44.96 billion (~US$49.3–50.4 billion), in line with the full-year range.

What changed from Q2 and from a year ago

Against the second quarter, total net sales rose 25.0%, from €9,326.5 million (~US$10.5 billion) to €11,662.0 million (~US$13.1 billion). Against the third quarter of 2025 the increase was 55.2%, from €7,516.0 million (~US$8.42 billion). Gross margin rose 3.5 percentage points from the second quarter and 5.9 points from a year earlier, when it was 51.6%.

Income from operations reached €5,172.8 million (~US$5.8 billion), more than double the €2,468.4 million (~US$2.77 billion) of Q3 2025. ASML sold 113 new and 8 used lithography systems in the quarter, against 86 and 5 in the second quarter. Reported net income of €4,960 million (~US$5.56 billion) flatters the comparison slightly because it includes a €509.7 million (~US$571 million) gain on equity investments, which is not part of ASML's lithography business.

Revenue and margin: systems versus the installed base

ASML splits sales into new and used systems on one side and Installed Base Management on the other. System sales rose 27.5% from the second quarter to €8,373.2 million (~US$9.38 billion). Installed Base Management rose 19.1% to €3,288.8 million (~US$3.69 billion) and 67.6% from a year earlier.

ASML's chief executive said Installed Base Management came in above guidance "as a result of the continued strong demand for productivity upgrades" and that "this drove the gross margin above guidance". That is the company's own explanation, and it matters for interpretation. A higher margin here is not, on the evidence of this report, proof of price increases on new tools. It is consistent with a richer mix of upgrade work and higher volumes absorbing fixed costs. ASML does not disclose margins by segment, so the exact contribution of each cannot be measured.

What Installed Base Management covers

ASML defines Installed Base Management sales as its net service and field option sales. In practice that covers servicing machines already in customers' fabs and selling field options and upgrades that raise the output or precision of those machines.

Upgrades deserve attention because they add capacity without a new tool shipping. When new systems are scarce, an upgrade that lifts throughput on an existing scanner is one of the few ways a chipmaker can get more wafers through lithography quickly. ASML said so directly: it continues "to provide significant wafer capacity to our customers through our productivity upgrade portfolio".

That does not make the whole segment subscription income. Service contracts tend to recur as the installed base grows, but upgrade sales depend on customer decisions and can be lumpy. Of the quarter's €3,289 million (~US$3.69 billion), ASML does not disclose how much was service and how much was upgrades.

The capacity question

Several different things are easy to confuse here. Customer demand forecasts are what chipmakers tell ASML they expect to need. ASML says customers "continue to increase their short- and medium-term equipment demand forecasts", driven primarily by their views on the size and duration of AI-related investment. Some customers are "expressing an interest in placing orders" for 2029 and even 2030. Interest is not an order, and this article does not treat it as one.

Orders are a separate step. ASML describes "order book momentum that continues to increase quarter on quarter this year", but the Q3 materials reviewed do not publish a bookings or backlog figure, so the size of that momentum cannot be quantified here. Shipments and recognised revenue are later still: a system booked today may be shipped and recognised as sales quarters later.

The constraint ASML names sits between these stages. In its Q2 release it said it plans to raise low-NA EUV and DUV immersion capacity by 30% in 2027 and is investigating a further 30% for 2028. It now expects even that plan not to fully meet demand in 2027 and 2028, and is studying ways to go beyond it for 2028. ASML does not quantify the gap, so we do not chart it.

Cash and context

On the investor call ASML reported free cash flow of €11.4 billion (~US$12.8 billion) in the quarter, a non-GAAP measure. The release says ASML bought back around €4.1 billion (~US$4.59 billion) of shares in the quarter under its 2026–2028 programme.

For context, SEMI's mid-year forecast of 14 July 2026 puts global sales of semiconductor manufacturing equipment at a record $165.9 billion in 2026, up 23.2% (SEMI's forecast, not ASML's). Silicon Analytica reading (interpretation): an order book reaching into 2029 suggests customers treat lithography capacity as a constraint, not a discretionary purchase; the risk is that orders are not the same as shipments, and ASML itself lists cancellations and push-outs among its risks.

Risks and counter-arguments

Demand forecasts can be revised down as easily as up. ASML's customer base for leading-edge lithography is concentrated in a small number of chipmakers, so a delay at one large customer can move a year's shipments. Customer capital programmes depend on AI spending continuing at today's pace; a pause by cloud operators would travel up the chain.

Export restrictions remain a structural risk to where ASML can ship, and the company's own supply depends on specialised suppliers whose capacity must rise alongside ASML's. Raising output by 30% or more in a year is an execution challenge in itself. Finally, the margin gain is linked to strong upgrade demand, which may not repeat every quarter.

What the next report needs to show

The thesis that ASML is capacity-constrained by durable AI demand would be strengthened if the fourth quarter lands within the €14.2–15.2 billion (~US$15.9–17 billion) range, if ASML gives concrete 2027 capacity and shipment plans, and if it discloses order-book data that turns "momentum" into a number. It would be weakened if customers push out deliveries, if Installed Base Management falls back and takes the margin with it, or if the 2028 capacity investigation produces no additional plan.

For now, the report says that the limiting factor in ASML's business is shifting from whether customers want more machines to how many ASML can build.
