ASML

The only company that can print the leading edge of logic and memory. A true monopoly in EUV.

Hold

Ten-year thesis

If you understand lithography, this is the widest industrial moat in technology. EUV took decades and a captive supplier network (Zeiss optics, Cymer sources). No credible second source exists this decade. A ten-year hold is a bet that transistors keep shrinking or packing, and that geopolitics does not permanently cap the installed base in China. Cyclical orders will whip the stock. The franchise will not.

The moat

Process knowledge, exclusive optics, and switching costs measured in years of tool qualification. TSMC, Intel, and Samsung cannot dual-source EUV. Efficient scale is absolute: the market supports one winner.

Switching costs96

Pain, risk, or retraining required to leave.

Network effects40

The product gets better as more people use it.

Intangibles & IP98

Patents, data, licenses, process knowledge, regulation.

Scale advantage95

Fixed costs spread over a volume rivals cannot match.

Cost advantage88

Structural ability to be the low-cost producer.

Brand70

Pricing power from trust, habit, or identity.

Tech overlay

This is the kind of tech Buffett would have loved if he had spent time in a fab: one customer set, irreplaceable capital equipment, multi-year qualification, and pricing power. High-NA EUV extends the runway. You do not need to forecast a GPU vendor to own the pick-and-shovel layer.

Owner earnings yield 3.0%. Yield is judged against quality, not against a single hurdle — a fortress can be fairly priced at a lower yield than a fragile name.
