ASML Says Its 2028 Tool Supply Will Miss Chip Demand
Matthew Leo · Published October 23, 2026 · Business & Policy
ASML says the chip industry wants more lithography equipment than it currently plans to supply in both 2027 and 2028. Customers are already expressing interest in orders for 2029 and 2030, according to the company’s October 14 results.
That is more consequential than a strong quarter. ASML’s extreme-ultraviolet and deep-ultraviolet systems are among the hardest parts of advanced chip production to expand. If its tools arrive late, new fab buildings and AI-chip designs cannot create finished capacity by themselves.
The quarter was already running faster
ASML reported third-quarter sales of €11.662 billion, up from €9.326 billion in the second quarter. That is a quarter-over-quarter increase of about 25 per cent, calculated from the company’s published figures.
New lithography systems sold rose from 86 to 113, an increase of about 31 per cent. Net income increased from €2.918 billion to €4.960 billion, or about 70 per cent. These calculations describe two reported quarters; they are not annual growth forecasts.
ASML now expects 2026 sales of €44 billion to €45 billion. It says the current plan to increase low-NA EUV and immersion DUV capacity by 30 per cent in 2027, and potentially by another 30 per cent in 2028, will still not fully satisfy demand.
Why adding tool capacity is slow
Lithography systems depend on specialized optics, light sources, precision stages and a deep supplier network. ASML cannot solve the shortage by adding a generic assembly line. It must raise output without compromising nanometre-scale accuracy or the service capacity needed to keep installed tools productive.
The company says it is investigating additional 2028 capacity. It can also increase customers’ wafer output by upgrading existing machines and selling higher-throughput versions. Reuters reported that ASML is considering price increases beginning in 2027, with the full effect visible in 2028.
The constraint reaches beyond chipmakers
Cloud providers and AI developers place orders for accelerators, not lithography machines. But their demand travels backwards through Nvidia, AMD and custom-chip designers to foundries, memory makers and equipment suppliers. A bottleneck at ASML can therefore affect how quickly new compute capacity appears and what it costs.
Canadian buyers are unlikely to negotiate directly with ASML, but they can see the effects in accelerator lead times, cloud pricing and delayed data-centre deployments. Procurement plans that assume a smooth fall in AI hardware prices should include a slower-capacity scenario.
Mapletechie has previously explained why High-NA EUV needs larger masks for big AI chips and how memory shortages can reach PC buyers. The new ASML warning adds another supply-chain layer: the machines that make advanced chips are themselves capacity constrained.
