Is Castellum, Inc. CTM stock Halal to invest in?

Yes, as of September 2026, Castellum, Inc. stock (CTM) is classified as a Shariah compliant stock. For a Muslim investor, the question is settled by AAOIFI Shariah Standard No. 21, and Castellum, Inc. satisfies it in full this month: incidental non-permissible income sits inside the 5% threshold, neither interest-bearing debt nor interest-bearing investments breaches the 30% market capitalisation caps, and no impermissible preference share structure exists. The stock's current purification factor is 99.24%. Compliance is reassessed every month as updated screening data arrives, and a stock's status can change when new financial reports are released. You can always check the current status of Castellum, Inc. and explore other Shariah compliant stocks in the Tabadulat app.

How often is Castellum, Inc. CTM reviewed for Shariah compliance?

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 Monthly screening ensures the status shown for Castellum, Inc. reflects current financial data rather than an outdated assessment, and Tabadulat app users are notified if a holding in their portfolio becomes non-compliant.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

Yes, as of September 2026, Castellum, Inc. stock (CTM) passes the AAOIFI non-permissible income screen. AAOIFI permits a small tolerance because large companies rarely avoid incidental impermissible income entirely, most often interest on cash balances. The ceiling is 5% of total revenue, and Castellum, Inc. sits inside it in the latest screening. 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 Castellum, Inc. CTM pass the AAOIFI Interest Bearing Investments criteria?

Yes, as of September 2026, Castellum, Inc. stock (CTM) passes the AAOIFI interest-bearing investments screen. AAOIFI caps interest-earning holdings at 30% of market capitalisation so that shareholders do not materially profit from Riba. Measured against the latest data, Castellum, Inc.'s interest-bearing investments sit within 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 Castellum, Inc. CTM pass the AAOIFI Interest Bearing Debt criteria?

Yes, as of September 2026, Castellum, Inc. stock (CTM) passes the AAOIFI interest-bearing debt screen. Each month Tabadulat measures Castellum, Inc.'s interest-accruing borrowings against AAOIFI's 30% market capitalisation cap. The current screening shows the company within the limit, so the debt screen passes. Because market capitalisation changes daily, a company's debt ratio can drift toward or away from the limit even without new borrowing, which is why this screen is reassessed every month.

What is the dividend purification factor for Castellum, Inc. CTM stock?

As of September 2026, the dividend purification factor for Castellum, Inc. (CTM) is 99.24%. Purification (Tazkiyah) is the practice of donating to charity the portion of dividend income attributable to incidental non-permissible sources, typically interest earned on a company's cash, and AAOIFI methodology requires it even for fully compliant stocks. The purification factor is the figure Halal investors use to work out that donation on Castellum, Inc. dividends. It is recalculated with each monthly screening as new financial data arrives, and the Tabadulat app can help you calculate and track purification across your whole portfolio.

Does Castellum, Inc. CTM pass the AAOIFI Preference Share screen?

Yes, as of September 2026, Castellum, Inc. stock (CTM) 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. Castellum, 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.

September 2026: PASS

Castellum operates as a diversified technology and services company, concentrating on cybersecurity, electronic warfare, and simulation technology. The primary function of Castellum is to provide specialized solutions and services to government and commercial sectors, emphasizing the importance of secure and advanced technological infrastructures. Notable features of Castellum include its focus on acquiring smaller tech firms to expand its capabilities and market reach in defense and intelligence sectors. For Muslim investors, though, the most pressing question is simpler: is Castellum a Halal investment?

Is Castellum Shariah compliant?

Technology companies rarely fail AAOIFI screening on what they sell. Software, hardware and digital services are permissible business activities, so for a company like Castellum the Shariah question moves to the balance sheet: how much of its market value sits in interest bearing debt, how much of its cash earns Riba in conventional deposits, and whether incidental income from impermissible sources creeps past 5% of revenue. These are exactly the ratios AAOIFI Shariah Standard No. 21 polices, and they move every month with the share price.

Does Castellum pass the business activity test?

Yes. In the September 2026 screening Castellum holds an overall PASS, which a stock only earns when its core business clears the activity screen. 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 Castellum's income Halal?

Yes, within AAOIFI's tolerance. Castellum's 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 99.24% tells holders of CTM what share of each dividend to keep and what remainder to donate to charity.

Does Castellum 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 CTM re-screened every month, and the result above always shows the latest verdict.
