Summary

PROTHERM is younger than twelve months; there is no public track record yet to compute a bankruptcy probability from. The company has been active since 2026 and the Belgian State Gazette contains no insolvency or warning signals. No processed annual-account figures are available; this conclusion rests on registry and State Gazette data only.
