What the company does
Zai Lab is a Chinese biopharma: it sells licensed Western drugs in China (Zejula, Vyvgart, Nuzyra) and develops its own. Revenue comes from drug sales in China; still loss-making.
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-bearing debt / market cap
limit 30%
Interest-bearing debt $238.10M ÷ current market cap $2.65B = 9.0%

Pass
Cash & investments / market cap
limit 30%
Cash + interest-bearing securities $617.52M ÷ current market cap $2.65B = 23.3%

Pass
Non-compliant income / total revenue
limit 5%
Interest income $33.05M ÷ annual revenue $460.16M (2025) = 7.2%
7.2%
Fail
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 64.3% 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.
