Powerchip (PSMC) diligence pack

What they do

• Taiwanese foundry spanning memory and logic specialty processes.
• Primary segment: Foundry / Pure-Play Foundry.
• Key products in the dataset: specialty DRAM, logic foundry.
• Market position in that segment: challenger.

Role in the chain

• Powerchip (PSMC) is a market challenger in Foundry (Pure-Play Foundry), headquartered in Taiwan. Taiwanese foundry spanning memory and logic specialty processes.
• 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: 8.
• Named suppliers (first 1): Wafer Works.
• Named customers (first 8): Broadcom, MediaTek, NVIDIA, Qualcomm, AMD, Apple, SG Micro, Integrated Silicon Solution.
• 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: Taiwan.
• 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 TWSE:6770. 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.

• 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?
