# Woojin 105840 — Nuclear Instrumentation Without the Hype Premium

Research commentary only. Not investment advice. Not a buy/sell recommendation.

## Thesis

Woojin is the grounded nuclear support candidate. The appeal is not a broad nuclear slogan; it is whether nuclear-plant measuring instruments and related products are material enough to create a cleaner, more verifiable nuclear exposure than higher-hype alternatives.

## Why this ticker, not just the theme

The agent task is to prove whether the listed company actually maps to nuclear instrumentation economics. If the exposure is not material to revenue, orders, or profit, the story should be deleted.

## What must be true

- Nuclear instrumentation is a real and material product line.
- Orders convert into revenue and cash flow.
- Customer concentration is understandable and acceptable.
- Financial quality supports the exposure.
- The stock does not already price a nuclear story beyond what filings support.

## Kill test

Delete or downgrade the thesis if nuclear instrumentation is immaterial, orders do not convert, financial quality is weak, or the market price already embeds the story without filing support.

## Agent verification checklist

- KRX/KIND identity check for `105840`.
- DART product/revenue mix review.
- Order conversion and customer review.
- Profit quality and cash conversion.
- Nuclear project materiality proof.
- Liquidity/spread/depth check.

## Agent output prompt

Given Woojin `105840`, decide whether the nuclear-instrumentation thesis survives after DART/KRX/KIND, product mix, order conversion, customer concentration, financial quality, and liquidity checks.
