Manually identified reason
Automatic screening reads the industry label, not what's inside. This company's filings were checked by hand and a hidden prohibited activity was found:
Doubtful: pivot to an autonomous defense/drone-warfare platform — share not disclosed (Quantum Cyber; the 'Diagnostics' label is stale)
What the company does
Quantum Cyber (formerly Mainz Biomed, fully pivoted in 2026) is building post-quantum cryptography and an AI-driven autonomous defense platform (drone warfare, counter-UAS, naval mine countermeasures). The Yahoo label ('Diagnostics') is outdated; revenue is tiny (the defense line is considered by the screener).
What was checked
The AAOIFI standard has four steps: business activity first, then three financial ratios. Fail one and the stock is not halal.
