Is Tantalus Systems (GRID) stock Halal?
Under AAOIFI Shariah Standard No. 21, a Halal stock keeps non-permissible income below 5% of revenue and interest-bearing debt and investments each below 30% of market capitalisation. Tantalus Systems Holding, Inc. (GRID) passes all four screens as of September 2026, with a dividend purification factor of 98.77%.
Tantalus Systems is a technology company specializing in smart grid solutions designed to help utilities modernize and digitize their electricity distribution grids. By harnessing real-time data from both legacy infrastructure and advanced two-way devices, the company empowers utilities to improve operational efficiency, reliability, and sustainability. Its product ecosystem includes advanced metering infrastructure, intelligent connected devices, industrial IoT networks, and a comprehensive grid modernization platform that offers edge computing, enterprise software applications, and data analytics. For Muslim investors, though, the most pressing question is simpler: is Tantalus Systems a Halal investment?
Is Tantalus Systems Shariah compliant?
For industrial companies like Tantalus Systems, the product is rarely the problem; aircraft, vehicles and machinery are permissible. The exposure is leverage: fleets and factories are financed, and the 30% cap that AAOIFI Shariah Standard No. 21 places on interest bearing debt is the screen that decides most verdicts in this sector.
Does Tantalus Systems pass the business activity test?
Yes. In the September 2026 screening Tantalus Systems holds an overall PASS, which a stock only earns when its core business clears the activity screen. The activity itself raises no Shariah objection; the scrutiny belongs to the financing.
Is Tantalus Systems' income Halal?
Yes, within AAOIFI's tolerance. Tantalus Systems' 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 98.77% tells holders of GRID what share of each dividend to keep and what remainder to donate to charity.
Does Tantalus Systems 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 GRID re-screened every month, and the result above always shows the latest verdict.
