IQE diligence pack

What they do

• Leading epitaxial compound-semiconductor wafer maker (GaAs, GaN, InP).
• Primary segment: Materials / Silicon Wafers.
• Key products in the dataset: epitaxial wafers (GaAs, GaN, InP).
• Market position in that segment: leader.

Role in the chain

• IQE is a market leader in Materials (Silicon Wafers), headquartered in United Kingdom. Leading epitaxial compound-semiconductor wafer maker (GaAs, GaN, InP).
• 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: 1. Tracked customers: 11.
• Named suppliers (first 1): AIXTRON.
• Named customers (first 8): Broadcom, Samsung Electronics, SK hynix, TSMC, GlobalFoundries, Intel, Lumentum Holdings, Micron Technology.
• 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

• IQE itself is a leader in its primary segment.
• 1 of the tracked suppliers are a monopoly or leader: AIXTRON.
• 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: United Kingdom.
• 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 LSE:IQE. The company is unpriced in this dataset — do not treat a missing cap as zero.
• 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 1 tracked supplier for IQE. 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: 1 of IQE's tracked suppliers are a monopoly or leader (including AIXTRON). Which of those are actually single-source for the process step you care about?
• Ask: The dataset names 11 tracked customers for IQE. How concentrated is demand among those names, and which of them have a documented second source in this graph?
• Ask: IQE is positioned as a leader in Materials. How replaceable is this vendor on the process step you are buying?
• Ask: IQE is headquartered in United Kingdom. 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?
