Is Core Laboratories (CLB) stock Halal?
Core Laboratories, Inc. (CLB) is Shariah compliant in the September 2026 AAOIFI screening, passing all four AAOIFI screens. Dividends are purified using a factor of 100%. Tabadulat re-screens CLB monthly, and the status can change when new financial data arrives.
Core Laboratories is a global leader in providing reservoir description, production enhancement, and reservoir management services to the oil and gas industry. The primary function of the company is to optimize the production capabilities of its clients' reserves through advanced technology and specialized services. Core Laboratories engages deeply in areas such as fluid analysis, pressure-volume-temperature (PVT) testing, and core analysis, which are essential for understanding reservoir characteristics and maximizing hydrocarbon extraction efficiency. Before any of that matters to a Muslim investor, one question comes first: is Core Laboratories stock Halal?
Is Core Laboratories Shariah compliant?
For a resources company like Core Laboratories, AAOIFI Shariah Standard No. 21 has little quarrel with the product; the scrutiny falls on the financing. Heavy machinery and long project cycles are usually funded with debt, and the standard tolerates interest bearing borrowing only below 30% of market capitalisation.
Does Core Laboratories pass the business activity test?
Yes. In the September 2026 screening Core Laboratories holds an overall PASS, which a stock only earns when its core business clears the activity screen. The activity itself, extracting and selling resources, raises no Shariah objection; the scrutiny belongs to the financing.
Is Core Laboratories' income Halal?
Yes, within AAOIFI's tolerance. Core Laboratories' income from non-permissible sources stays below 5% of revenue in the September 2026 screening, and the small impure portion is handled through purification: the factor of 100% tells holders of CLB what share of each dividend to keep and what remainder to donate to charity.
Does Core Laboratories meet AAOIFI's debt and investment ratio requirements?
Yes. Both caps hold this month: interest bearing investments and interest bearing debt each stay below 30% of market capitalisation. Because the caps move with the share price, our Shariah Supervisory Board has CLB re-screened every month, and the result above always shows the latest verdict.
