ASML diligence pack

What they do

• Sole supplier of EUV lithography machines required for all leading-edge chips.
• Primary segment: Equipment (Front End) / Lithography.
• Key products in the dataset: EUV scanners, DUV scanners.
• Market position in that segment: monopoly.

Role in the chain

• ASML is a market monopoly in Equipment (Front End) (Lithography), headquartered in Netherlands. Sole supplier of EUV lithography machines required for all leading-edge chips.
• Ask: On the step you actually buy, is this company the process owner, a second source, or a distributor? The segment label is not a substitute for that answer.

Counterparties on the graph

• Tracked suppliers: 10. Tracked customers: 11.
• Named suppliers (first 8): Carl Zeiss SMT, TRUMPF, Atlas Copco, VAT Group, Advanced Energy, Brooks Automation, Horiba, MKS Instruments.
• Named customers (first 8): Mitsui Chemicals, Inc., Samsung Electronics, SK hynix, TSMC, GlobalFoundries, Intel, Micron Technology, SMIC.
• Ask: Which of those edges are in a filing or a primary-source quote, and which are segment-inferred? Do not treat the two as the same fact.

Concentration and replaceability

Operator section

• ASML itself is a monopoly in its primary segment.
• 4 of the tracked suppliers are a monopoly or leader: Carl Zeiss SMT, TRUMPF, Atlas Copco, VAT Group.
• Ask: If the named monopoly or leader supplier stopped shipping, is there a qualified second source on that process step? If the dataset does not name one, do not assume one exists.

Geography and jurisdiction

• Headquarters country in the dataset: Netherlands.
• Ask: Where do the fabs, plants or logistics nodes actually sit, versus the HQ country on this record? This dataset records headquarters, not every site.

Public-markets facts (only what is on the record)

Investor section

• Public company, ticker NASDAQ:ASML. A live market cap is on the company profile; this pack does not restate it as a diligence conclusion.
• Ask: What does the latest reported period (if any) say about capacity, backlog and customer concentration? If the company page has no revenue figure, that number is not in this dataset.

Operator checklist

Operator section

• Ask: The dataset records 10 tracked suppliers for ASML. Which of those edges are researched (named in a filing or primary source) versus segment-inferred, and what happens if one of them stops shipping?
• Ask: 4 of ASML's tracked suppliers are a monopoly or leader (including Carl Zeiss SMT, TRUMPF, Atlas Copco, VAT Group). Which of those are actually single-source for the process step you care about?
• Ask: The dataset names 11 tracked customers for ASML. How concentrated is demand among those names, and which of them have a documented second source in this graph?
• Ask: ASML is positioned as a monopoly in Equipment (Front End). How replaceable is this vendor on the process step you are buying?
• Ask: ASML is headquartered in Netherlands. What jurisdiction, export-control or logistics risk sits at that HQ, versus at the fabs or plants the filings actually name?

Investor checklist

Investor section

• Ask: Is the graph position (monopoly / leader / major / challenger / niche) the thing you are underwriting, or a product line the one-liner does not cover?
• Ask: Which named customers in this graph could switch, and which named suppliers could not be replaced in a year? Count only names this dataset actually lists.
• Ask: What is not in this dataset — site-level capacity, contract terms, revenue split by customer — that you still need from a filing or a call?
