Reported fundamentals
There is no stock score on this page. The score is computed from audited XBRL filings on SEC EDGAR and includes a 20-point insider component built from Form 4s, and a Korean company files neither, so a grade here would be measuring something different from the same letter on a US hub. These are the reported figures instead.

What Soulbrain does
Soulbrain makes the chemicals a fab consumes: high-purity etchants that remove material precisely, cleaning solutions, and electrolyte materials for batteries. These are consumables, bought and used continuously rather than installed once, so revenue tracks how much production is actually running.
Materials became a strategic question in Korea after Japan restricted exports of several semiconductor chemicals in 2019, and domestic supply of those inputs has been a national priority since. Soulbrain is one of the companies that position addresses. The business is less exciting than the equipment names and more predictable, which is the trade.
Soulbrain is run by Park Young-soo (박영수), CEO, since March 2025.
Soulbrain has no US listing. Buying the shares means buying the Seoul line, which most US brokerage accounts cannot do directly.
