Amkor Technology diligence pack

What they do

• Second-largest OSAT; building advanced packaging capacity in Arizona.
• Primary segment: OSAT / Outsourced Assembly & Test.
• Key products in the dataset: assembly, test, 2.5D packaging.
• Market position in that segment: major.

Role in the chain

• Amkor Technology is a market major in OSAT (Outsourced Assembly & Test), headquartered in United States. Second-largest OSAT; building advanced packaging capacity in Arizona.
• 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: 16. Tracked customers: 6.
• Named suppliers (first 8): ASMPT, BE Semiconductor Industries, DISCO, Kulicke & Soffa, Mitsui High-tec, Teradyne, TOWA, Chang Wah Technology.
• Named customers (first 6): Broadcom, MediaTek, NVIDIA, Qualcomm, AMD, Apple.
• 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

• 7 of the tracked suppliers are a monopoly or leader: ASMPT, BE Semiconductor Industries, DISCO, Kulicke & Soffa, Mitsui High-tec, Teradyne.
• 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 States.
• 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:AMKR. 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 16 tracked suppliers for Amkor Technology. 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: 7 of Amkor Technology's tracked suppliers are a monopoly or leader (including ASMPT, BE Semiconductor Industries, DISCO, Kulicke & Soffa). Which of those are actually single-source for the process step you care about?
• Ask: The dataset names 6 tracked customers for Amkor Technology. How concentrated is demand among those names, and which of them have a documented second source in this graph?
• Ask: Amkor Technology is headquartered in United States. What jurisdiction, export-control or logistics risk sits at that HQ, versus at the fabs or plants the filings actually name?
• Ask: Amkor Technology trades as NASDAQ:AMKR. What does the latest reported period say about capacity and backlog versus the graph position above?

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?
