What the company does
Core Laboratories analyzes oil and gas reservoirs: lab studies of rock and fluid samples (to assess reserves) and production-enhancement technologies. Customers are oil companies; its money comes from analysis services and product 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: $440.49M.
For information (AAOIFI 3/1 note): cash + receivables are 23.7% 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.
