ASML - Not a normal industry company

ASML’s business model looks like low-volume hardware, but it behaves like installed-base compounding. Each system is extraordinarily expensive, runs for a long time, and becomes integrated into a fab’s workflow, tooling, maintenance routines, and process recipes. Once deployed, the relationship doesn’t end; it deepens. Service, upgrades, parts, and software grow as the installed base grows and as customers chase higher uptime and better yields. In other words, ASML sells a critical asset and then monetizes the lifetime of that asset. That combination, high upfront value plus recurring monetization, tends to produce resilient margins and strong free cash generation over full cycles.
Demand isn’t driven by consumer electronics whims so much as structural compute intensity. AI is the cleanest example: training and inference scale best when chips get denser, faster, and more power-efficient, which pushes fabs toward more advanced lithography and more layers of precision patterning. Even if end markets wobble quarter to quarter, the long-run direction stays the same: the world wants more compute, and the only way to get it economically is continued process advancement. Add in geopolitical “fab duplication” across regions, and you don’t reduce tool demand; you often multiply it, because redundancy means building more leading-edge capacity in parallel.

The core reason ASML compounds is simple: it sits at the intersection of physics, supply chain complexity, and customer lock-in. EUV systems are not “machines”; they’re industrial ecosystems in a box, combining extreme light sources, vacuum environments, optics polished to atomic tolerances, nanometer positioning, and software that calibrates reality into compliance. Even for the world’s richest chipmakers such as TSMC, Samsung, and Intel, there is no practical “build it yourself” path and no second vendor that can step in at scale. That creates a rare market structure where the most powerful buyers in tech still behave like price takers, because the alternative is falling behind on process technology.
