⚠ Capital Intensity Cuts Customers' Appetite in DownturnsModerate threat

The capital intensity that forces customers to buy from ASML also makes them acutely cautious about when to buy, and that caution is a source of cyclical volatility. Because a fab and its machines cost tens of billions, customers are terrified of over-building into a downturn and being left with expensive idle capacity, so at the first sign of softening demand they defer, delay, and cut their capital spending hard — and lithography orders are among the biggest and most deferrable line items. The very expense that makes the machines a non-negotiable part of a fab makes the decision to commit to a new fab intensely cyclical.

This is why ASML, despite its monopoly, cannot escape the semiconductor cycle: its customers' capital-spending decisions swing violently with their view of future demand, and those swings drive ASML's order flow. In a boom, capital intensity works for ASML — customers race to build capacity and buy every machine they can. In a bust, it works against — the same customers freeze their vast commitments and wait. The monopoly guarantees ASML gets the orders whenever fabs are built; it does not guarantee the fabs are built on a smooth schedule, and the enormous cost of getting the timing wrong makes ASML's customers prone to lurching between feast and famine — when each machine costs €200 million or more, timing is everything¹ — a rhythm ASML, for all its power, must ride rather than control.
