ASML Says Currently Planned Output Falls Short of Customer Demand in 2027 and 2028

Analysis

ASML said on October 14 that its currently planned output for 2027 and 2028 will not fully meet customer demand.

The statement came with record results. ASML reported third-quarter net sales of €11.7 billion, a 57.5% gross margin and €5.0 billion of net income. It guided fourth-quarter sales to €14.2 billion to €15.2 billion and full-year 2026 sales to €44 billion to €45 billion ( ASML results release, October 14 ). Third-quarter sales compare with €7.5 billion a year earlier, according to ASML's official quarterly financial statements .

What changed

Company statements in ASML's results release and official results transcript:

Chief executive Christophe Fouquet said customers have raised their short- and medium-term demand forecasts, mainly because of AI-related investment. Some now want to place orders for 2029 and 2030.

ASML had already committed to a 30% increase in low-NA EUV and DUV immersion capacity for 2027. A further 30% for 2028 is under review, and the company is now studying whether 2028 capacity can go higher still.

Even so, Fouquet said, "our supply as currently planned for both 2027 and 2028 will not fully meet the demand" of customers.

Finance chief Roger Dassen expects about 65 low-NA EUV systems in 2026, compared with 44 last year.

He expects memory system sales to grow about 75% in 2026 and logic about 10%. Third-quarter system sales were 54% logic and 46% memory.

ASML is raising prices on "the most critical products," with the effect starting in 2027.

China is expected to be about 20% of 2026 sales.

The results release and ASML's official video transcript are the primary records for these statements. The interest in 2029–2030 orders is not a booking figure: ASML did not disclose bookings for those years.

Why it matters: the causal chain

Observed: AI data-center investment → chipmakers raise demand forecasts for leading-edge logic and memory → they need more lithography tools → ASML says planned tool output for 2027–28 is below that demand.

Conditional: if tool supply is the binding limit, chipmakers' capacity additions could be paced by ASML deliveries rather than by their own budgets. That would support pricing for the tools, as ASML is already raising prices on critical products. It could also keep supply of the most advanced chips and memory tight, which matters for AI build-out costs.

The memory mix is the detail to watch. A 75% expected rise in memory system sales suggests chipmakers are adding capacity for the memory AI systems need, not only for processors.

Counter-case

Forecasts are not orders. Customer demand forecasts rose during earlier semiconductor booms and were later cut. Interest in 2029–2030 slots is a planning signal and can disappear if AI returns disappoint or financing tightens.

Financing is the other constraint. A financing squeeze could raise the bar for long-lived AI infrastructure and cause customers to delay fabs.

Execution risk on both sides. Dassen said customers must build new fabs on time in 2027–28 to take the tools. Construction delays could ease the shortage without any change in demand.

China exposure. About a fifth of 2026 sales come from China, which is subject to export-control decisions outside ASML's control.

Market reaction is not settled. Short-term share-price moves do not establish whether the capacity warning changed investors' long-term expectations.

What we're watching

Whether ASML delivers fourth-quarter sales within its €14.2–15.2 billion range.

ASML's 2027 guidance and any decision to go beyond 30% capacity growth for 2028.

Capital spending guidance from the largest logic and memory chipmakers, the customers whose forecasts drive this demand.

Memory pricing and any change in export-control rules affecting sales to China.

What would change our view

The shortage claim weakens if customers cut capital spending plans or delay fab openings in their next updates, or if ASML stops describing 2027–28 supply as short. It strengthens if ASML commits to more 2028 capacity and customers still report tool shortages.
