This report evaluates CETY's Shariah compliance based on financial ratios, business activities, index inclusions, and multi-perspective analyses. The company faces significant challenges due to high interest income ratio, leading to non-compliance across major standards. While the core business in the industry appears permissible, financial screening failures dominate the assessment. No inclusion in Shariah indices confirms overall non-compliance. Purification is required for any potential holdings, but investment is not recommended without restructuring.
