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:
Ammunition manufacturing (National Presto — AMTEC 40 mm grenades, defense segment ~70%)
What the company does
National Presto Industries has three units: defense (AMTEC — 40 mm grenades and ammunition for the US Army, about 70% of revenue), housewares (Presto cookers, popcorn makers) and safety (Rusoh fire extinguishers). Its money comes mostly from defense contracts.
What was checked
The AAOIFI standard has four steps: business activity first, then three financial ratios. Fail one and the stock is not halal.
