What the company does
Rubico (Greece/Marshall Islands, spun off from Top Ships in 2025) owns and operates two Suezmax oil tankers, with a chemical/product tanker and a megayacht under construction. Its money comes from vessel charters.
What was checked
The AAOIFI standard has four steps: business activity first, then three financial ratios. Fail one and the stock is not halal.
Business activity
No prohibited activity

Interest income $62K ÷ annual revenue $23.52M (2025) = 0.3%

Pass
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.
For information (AAOIFI 3/1 note): cash + receivables are 8.8% 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.
