Is 374Water (SCWO) stock Halal?

374Water is a company at the forefront of sustainable waste management technology. It focuses on developing innovative solutions that transform waste streams into valuable resources, with an emphasis on environmental responsibility. The company's primary technology uses supercritical water oxidation to process waste materials safely and efficiently, converting them into clean water and non-toxic gases. This approach significantly impacts industrial sectors by offering a sustainable alternative for waste disposal and resource recovery. For Muslim investors, though, the most pressing question is simpler: is 374Water a Halal investment?

Is 374Water Shariah compliant?

Yes. In the October 2026 screening 374Water (SCWO) passes AAOIFI Shariah Standard No. 21: the business activity screen and every financial ratio screen hold. For industrial companies like 374Water, 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 374Water pass the business activity test?

Yes. In the October 2026 screening 374Water 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 374Water's income Halal?

Yes, within AAOIFI's tolerance. 374Water's income from non-permissible sources stays below 5% of revenue in the October 2026 screening, and the small impure portion is handled through purification: the factor of 99.2% tells holders of SCWO what share of each dividend to keep and what remainder to donate to charity. On a dividend yield of around None, the purification amount is modest but real.

Does 374Water 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, measured against a market capitalisation of $51.4M (market data as of 1 October 2026). Because the caps move with the share price, our Shariah Supervisory Board has SCWO re-screened every month, and the result above always shows the latest verdict.

Why do other halal screeners show a different verdict for 374Water?

Screeners can disagree without either being wrong. AAOIFI Shariah Standard No. 21, which Tabadulat applies, measures interest bearing debt and investments against market capitalisation with a 30% ceiling. MSCI and FTSE measure them against total assets with a 33% ceiling, and S&P and Dow Jones Islamic use a multi year average of market capitalisation. Data dates differ too, because each provider reads filings and prices on its own schedule. The same company can therefore pass one standard and fail another in the same month. Tabadulat publishes one answer, the AAOIFI result as of October 2026, and re-screens it every month.

Tabadulat is an ADGM regulated brokerage whose license covers Shari'a Compliant Regulated Activities, as the FSRA permission names them. New to the terminology? Gharar and Maysir, Sukuk, Zakat and purification are all explained in plain English.
