Yangtze Memory (YMTC) diligence pack

What they do

• China's NAND flash champion with Xtacking architecture.
• Primary segment: Memory / NAND.
• Key products in the dataset: 3D NAND.
• Market position in that segment: challenger.

Role in the chain

• Yangtze Memory (YMTC) is a market challenger in Memory (NAND), headquartered in China. China's NAND flash champion with Xtacking architecture.
• 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: 3. Tracked customers: 4.
• Named suppliers (first 3): Suzhou Crystal Clear Chemical (Jingrui), Hwatsing Technology, Piotech.
• Named customers (first 4): Dell Technologies, Apple, Hewlett Packard Enterprise, Super Micro Computer.
• 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

• None of the tracked suppliers are labelled monopoly or leader in this dataset.
• 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: China.
• 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

• Private company in this dataset: no ticker, no market cap. Do not invent a valuation.
• 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 3 tracked suppliers for Yangtze Memory (YMTC). 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: The dataset names 4 tracked customers for Yangtze Memory (YMTC). How concentrated is demand among those names, and which of them have a documented second source in this graph?
• Ask: Yangtze Memory (YMTC) is headquartered in China. What jurisdiction, export-control or logistics risk sits at that HQ, versus at the fabs or plants the filings actually name?
• Ask: Yangtze Memory (YMTC) is private in this dataset (no ticker). What primary-source filings or audited statements exist, and what is still only a one-liner?
• Ask: Before treating any edge as a verified relationship, check the provenance labels on the company page and the method note at /methodology.

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?
