Kioxia Holdings diligence pack

What they do

• NAND inventor (ex-Toshiba Memory); operates JV fabs with SanDisk.
• Primary segment: Memory / NAND.
• Key products in the dataset: BiCS NAND, SSDs.
• Market position in that segment: major.

Role in the chain

• Kioxia Holdings is a market major in Memory (NAND), headquartered in Japan. NAND inventor (ex-Toshiba Memory); operates JV fabs with SanDisk.
• 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: 4. Tracked customers: 8.
• Named suppliers (first 4): Adeia Inc., Phison Electronics, Silicon Motion, Powertech Technology (PTI).
• Named customers (first 8): Dell Technologies, Kingston Technology, Silicon Motion, ADATA Technology, Apple, Hewlett Packard Enterprise, SanDisk, 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

• 3 of the tracked suppliers are a monopoly or leader: Adeia Inc., Phison Electronics, Silicon Motion.
• 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: Japan.
• 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 TSE:285A. 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 4 tracked suppliers for Kioxia Holdings. 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: 3 of Kioxia Holdings's tracked suppliers are a monopoly or leader (including Adeia Inc., Phison Electronics, Silicon Motion). Which of those are actually single-source for the process step you care about?
• Ask: The dataset names 8 tracked customers for Kioxia Holdings. How concentrated is demand among those names, and which of them have a documented second source in this graph?
• Ask: Kioxia Holdings is headquartered in Japan. What jurisdiction, export-control or logistics risk sits at that HQ, versus at the fabs or plants the filings actually name?
• Ask: Kioxia Holdings trades as TSE:285A. 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?
