Is Phathom Pharmaceuticals, Inc. PHAT stock Halal to invest in?

No, as of September 2026, Phathom Pharmaceuticals, Inc. stock (PHAT) 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. Phathom Pharmaceuticals, Inc. 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 Phathom Pharmaceuticals, Inc. and discover Shariah compliant alternatives among the Halal stocks in the Tabadulat app.

How often is Phathom Pharmaceuticals, Inc. PHAT reviewed for Shariah compliance?

Tabadulat reviews Phathom Pharmaceuticals, Inc. PHAT 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screening ensures the status shown for Phathom Pharmaceuticals, Inc. reflects current financial data rather than an outdated assessment, and Tabadulat app users are notified if a holding in their portfolio becomes non-compliant.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 Phathom Pharmaceuticals, Inc. PHAT pass the AAOIFI Non Permissible Income criteria?

Yes, as of September 2026, Phathom Pharmaceuticals, Inc. stock (PHAT) passes the AAOIFI non-permissible income screen. In practice this screen asks a simple question: how much of the company's revenue comes from sources Islam prohibits, such as Riba, conventional financial services, alcohol, gambling or tobacco? AAOIFI allows at most 5%, and Phathom Pharmaceuticals, Inc. stays below that line this month. 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 Phathom Pharmaceuticals, Inc. PHAT pass the AAOIFI Interest Bearing Investments criteria?

Yes, as of September 2026, Phathom Pharmaceuticals, Inc. stock (PHAT) passes the AAOIFI interest-bearing investments screen. This screen looks at where the company parks its cash: conventional deposits, bonds, treasury bills and money-market funds all earn Riba, so AAOIFI caps them at 30% of market capitalisation. Phathom Pharmaceuticals, Inc. stays inside that cap in the latest screening. 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 Phathom Pharmaceuticals, Inc. PHAT pass the AAOIFI Interest Bearing Debt criteria?

No, as of September 2026, Phathom Pharmaceuticals, Inc. stock (PHAT) 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. Phathom Pharmaceuticals, Inc.'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 Phathom Pharmaceuticals, Inc. PHAT stock?

Phathom Pharmaceuticals, Inc. (PHAT) 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 Phathom Pharmaceuticals, Inc. returns to compliance in a future monthly screening, its purification factor will be published alongside its updated status in the Tabadulat app.

Does Phathom Pharmaceuticals, Inc. PHAT pass the AAOIFI Preference Share screen?

Yes, as of September 2026, Phathom Pharmaceuticals, Inc. stock (PHAT) 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. Phathom Pharmaceuticals, Inc. 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.

Phathom Pharmaceuticals is a clinical-stage biopharmaceutical company focused on developing and commercializing novel treatments for gastrointestinal diseases. Its primary function is to address unmet medical needs in the field of gastroenterology through innovative research and drug development. The company is notably advancing its pipeline with lead candidates targeting acid-related disorders, leveraging cutting-edge scientific methodologies and research partnerships to streamline novel solutions. Before any of that matters to a Muslim investor, one question comes first: is Phathom Pharmaceuticals stock Halal?

Is Phathom Pharmaceuticals Shariah compliant?

The Shariah case on a technology company like Phathom Pharmaceuticals is rarely about the product. What AAOIFI Shariah Standard No. 21 examines is the money around the product: cash parked in instruments that earn Riba, borrowing measured against a market capitalisation that moves daily, and any incidental income from sources Islam prohibits, which must stay below 5% of revenue.

Does Phathom Pharmaceuticals pass the business activity test?

The activity screen is only part of the picture this month: Phathom Pharmaceuticals currently fails the interest-bearing debt screen, so the overall verdict is not compliant regardless of the business itself. The watch item for technology names is incidental: cash returns and platform content can carry impermissible elements, which AAOIFI tolerates only below the thresholds.

Is Phathom Pharmaceuticals' income Halal?

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

Does Phathom Pharmaceuticals 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.
