Is CytoSorbents Corp. CTSO stock Halal to invest in?

No, as of September 2026, CytoSorbents Corp. stock (CTSO) is not currently classified as a Shariah compliant stock. This verdict follows the screening methodology of AAOIFI (the Accounting and Auditing Organization for Islamic Financial Institutions), whose Shariah Standard No. 21 is the leading global benchmark for screening Halal stocks. To qualify as Halal under this standard, a company must keep non-permissible income below 5% of total revenue, keep both interest-bearing investments and interest-bearing debt below 30% of market capitalisation, and have no impermissible preference share structure. CytoSorbents Corp. currently does not meet the threshold for the interest-bearing debt screen. Because screenings are refreshed monthly as new financial reports are published, a non-compliant stock can regain compliant status if its financial structure changes. You can track the latest status of CytoSorbents Corp. and discover Shariah compliant alternatives among the Halal stocks in the Tabadulat app.

How often is CytoSorbents Corp. CTSO reviewed for Shariah compliance?

Tabadulat reviews CytoSorbents Corp. CTSO for Shariah compliance every month. Each review applies the AAOIFI Shariah Standard No. 21 methodology, screening the company's business activities, non-permissible income, interest-bearing investments, interest-bearing debt, and preference shares, against the company's latest available financial data. The process operates under the direct supervision of Tabadulat's dedicated Shariah Supervisory Board of Islamic finance scholars. Because compliance depends on financial ratios that move with market capitalisation and reported results, a stock's status can change from one review to the next. Monthly screening ensures the status shown for CytoSorbents Corp. reflects current financial data rather than an outdated assessment, and Tabadulat app users are notified if a holding in their portfolio becomes non-compliant.

Does CytoSorbents Corp. CTSO pass the AAOIFI Non Permissible Income criteria?

Yes, as of September 2026, CytoSorbents Corp. stock (CTSO) passes the AAOIFI non-permissible income screen. Under AAOIFI Shariah Standard No. 21, income from impermissible sources (such as interest or Riba, conventional financial services, alcohol, gambling, or tobacco) must remain below 5% of a company's total revenue. CytoSorbents Corp.'s income from non-permissible sources is currently within this 5% threshold. Even permissible levels of incidental impure income should still be purified: investors donate the corresponding share of dividends to charity, as reflected in the stock's purification factor. This screen is reassessed monthly using the company's latest financial disclosures.

Does CytoSorbents Corp. CTSO pass the AAOIFI Interest Bearing Investments criteria?

Yes, as of September 2026, CytoSorbents Corp. stock (CTSO) passes the AAOIFI interest-bearing investments screen. Each month Tabadulat compares CytoSorbents Corp.'s holdings in interest-earning instruments, such as conventional deposits, bonds and treasury bills, against AAOIFI's 30% market capitalisation cap. The current screening shows the company inside the limit. Because the ratio is measured against market capitalisation, it can move with the share price as well as the balance sheet, which is why Tabadulat rescreens the stock every month.

Does CytoSorbents Corp. CTSO pass the AAOIFI Interest Bearing Debt criteria?

No, as of September 2026, CytoSorbents Corp. stock (CTSO) does not pass the AAOIFI interest-bearing debt screen. Under AAOIFI Shariah Standard No. 21, a company's borrowings that accrue interest (conventional bank loans, bonds and similar Riba-based financing) must remain below 30% of its market capitalisation. CytoSorbents Corp.'s interest-bearing debt currently exceeds this 30% limit, meaning the company relies on Riba-based financing beyond the level AAOIFI permits for a Halal investment. A company can return to compliance by reducing debt or through changes in market capitalisation, and the screen is reassessed monthly.

What is the dividend purification factor for CytoSorbents Corp. CTSO stock?

CytoSorbents Corp. (CTSO) is currently classified as not Shariah compliant, so no dividend purification factor applies, because purification factors are calculated only for stocks that pass the AAOIFI screens. Purification (Tazkiyah) is the practice of donating to charity the small portion of dividend income that stems from incidental non-permissible sources, such as interest earned on a compliant company's cash deposits. For non-compliant stocks the issue is not purification but eligibility: under AAOIFI Shariah Standard No. 21 the stock does not currently qualify as a Halal investment. If CytoSorbents Corp. returns to compliance in a future monthly screening, its purification factor will be published alongside its updated status in the Tabadulat app.

Does CytoSorbents Corp. CTSO pass the AAOIFI Preference Share screen?

Yes, as of September 2026, CytoSorbents Corp. stock (CTSO) passes the AAOIFI preference share screen. AAOIFI Shariah Standard No. 21 prohibits investing in preference shares because they grant holders guaranteed or priority rights to dividends and capital ahead of ordinary shareholders, a structure that conflicts with the Shariah principle that investors should share profit and loss in proportion to their ownership. CytoSorbents Corp. has no impermissible preference share structure affecting its ordinary shares, so the stock is compliant on this criterion. Like all AAOIFI screens, this is verified in each monthly review.

CytoSorbents is a biotechnology company that specializes in advanced blood purification technologies designed to treat life-threatening conditions in intensive care units and other hospital settings. The company's flagship product, CytoSorb, is a hemoadsorption cartridge that removes cytokines and other inflammatory mediators from blood. This device aims to help control excessive inflammation, which is a critical factor in numerous conditions such as sepsis, cardiac surgery, and trauma. Before any of that matters to a Muslim investor, one question comes first: is CytoSorbents stock Halal?

Is CytoSorbents Shariah compliant?

Healthcare rarely troubles the activity screen; treating illness is permissible work. For CytoSorbents, the AAOIFI Shariah Standard No. 21 verdict turns on the balance sheet instead: research is capital hungry, and interest bearing debt and investments must each stay below 30% of market capitalisation.

Does CytoSorbents pass the business activity test?

The activity screen is only part of the picture this month: CytoSorbents currently fails the interest-bearing debt screen, so the overall verdict is not compliant regardless of the business itself. Treating illness is permissible work; the scrutiny belongs to the financing behind it.

Is CytoSorbents' income Halal?

Yes, within AAOIFI's tolerance. CytoSorbents' income from non-permissible sources stays below 5% of revenue in the September 2026 screening.

Does CytoSorbents meet AAOIFI's debt and investment ratio requirements?

Not in full. Interest bearing debt currently exceeds the 30% cap, while the other ratio stays within it. One breach is enough to fail the screening; the ratios are reassessed monthly under our Shariah Supervisory Board.
