⚠ Essential to a Cyclical, AI-Dependent DemandHigh threat

Being essential to advanced chips is a magnificent position, but it chains ASML to the fortunes of an industry famous for its violent cycles. Semiconductor demand booms and busts; foundries over-build in the good times and slam the brakes in the bad, and when they do, orders for €200-million lithography machines are among the first things deferred. ASML is indispensable to the leading edge, but the leading edge itself is bought in waves, and the company's revenue, for all its backlog, ultimately rides those waves.

The sharper version of the risk today is concentration in a single driver: the artificial-intelligence build-out. Much of the current surge in demand — and the guidance raises and the soaring stock — rests on AI-driven capacity expansion continuing at its recent torrid pace. If AI investment cools, digests, or disappoints, the capacity plans of ASML's customers would follow, and the acceleration the market is now extrapolating could stall. Being essential does not make demand steady; it makes ASML a leveraged, indispensable bet on an industry — and, right now, on one boom within it — that has never grown in a straight line — the 2026 guidance raise to €43–45 billion is the boom half of that sentence¹.
