What the company does
Federal Signal makes specialty vehicles and equipment: street sweepers, sewer cleaners, tow trucks, plus emergency lights and sirens (police, fire). Its money comes from equipment sales.
What was checked
The AAOIFI standard has four steps: business activity first, then three financial ratios. Fail one and the stock is not halal.

No data
Figures from the company's filings (2026-06-30), USD. Market cap is a 36-month average (the S&P Shariah index approach), so a one-day price move does not flip the verdict. Today's market cap: $6.88B.
For information (AAOIFI 3/1 note): cash + receivables are 14.4% of total assets (2026-06-30). AAOIFI recommends tangible assets of at least one third — this figure does not affect the verdict, and other major screeners do not apply it either.
